The aim of this study is to choose the most efficient irrigation contractors for government procurement based on a multi-criteria and data analysis. When proposals are presented, the awarding board will determine the tender assessment measures of the bids received in advance. The research recommend a decision-making framework to support the awarding board in this hard mission while retaining a clear process in line with government procurement rules and conditions, as well as ensuring equal and fair assessment of all proposals. In this respect, the cross-efficiency evaluation has been used among the eligible candidates to select the best contractor. The suggested methodology allows the evaluation of quantitative contractor choice data and preserves the transparency functionality required by government procurement. Additionally, all proposals are analyzed similarly without any subjective adjusting by the public officers according to the same quantitative weights. A case study linked to the tender of an Egyptian public organization for selecting the efficient irrigation contractors confirms the efficiency of this approach.

Palm date (Phoenix dactylifera L.) began to be popularly developed in the wet tropics, especially in Aceh Province. The cultivation is carried out on sub-marginal land that cannot be grown by land cover crops with sloping land more than 10. Without conservation efforts, gradually, the area used will experience degradation due to monoculture cultivation methods. The unavailability of data and conservation field testing in tropical date palm plantations makes it difficult for decision-makers and researchers to determine appropriate land conservation efforts. Therefore, this study aims to analyze the effect of one of the mechanical conservation methods in the form of silt pits in date palm plantations that are cultivated in the tropics. Two experimental plots (with and without using silt pit) with an area of 88 m2 each was designed at the date palm plantation in Blang Bintang sub-district, Aceh Besar Regency, Aceh Province. The parameters of natural rainfall, surface runoff, and erosion rates are measured, analyzed, and compared during the experiment. The results show that natural rainfall has a very significant effect in causing surface runoff and erosion rates that occur in date palm plantations. The application of the silt pit has been able to reduce the effects of surface runoff and erosion rates of 88.55%, 85.42%, respectively. A model for estimating erosion rates that occur on date palm plantations has also been developed with a reliable level of accuracy.

The engineering programs in most of the Jordanian Universities don’t include the essential basic background to use the thermal insulation in the building and the philosophy of teaching by hand. Additionally, the private construction sector in Jordan doesn’t have the vital information or the experience of using the thermal insulation concept in their constructions. This study aims to establish a roadmap for developing the engineering program in Jordanian Universities to intrude the concept of thermal insulation and teaching by hand philosophy. This will enhance the higher education institutions in the field of thermal insulation for engineering constructions in Jordan. The study will focus on establishing laboratories to receive the necessary equipment to improve the teaching by hands and modernising at least four courses mainly in the construction material and the heat transfer topics. These courses will be introduced in the civil engineering and the mechanical engineering curricula and built based on the Engineering courses. The study will, therefore, contribute to improve the quality of higher education and enhancing its relevance for the labor market and society. It will also initiate the awareness of thermal insulation into the Jordanian governmental and private construction sectors.

Solar Power Plants is a generator that utilizes solar energy to produce electricity. However, the solar power plants needs to be improved optimization in the measurement of electrical quantities on power and efficiency that is still done with a multimeter and manual calculations. Measuring the solar power plants electricity needs to be done regularly so that every condition can be monitored properly. One effective and efficient way to overcome this is to use a realtime measurement system. This tool has a voltage sensor to read the voltage value of solar panel and a current sensor to read the current generated by solar panel. The Raspberry Pi 3 microcontroller is used as the main processor to get the value of solar panel electrical power and absorption efficiency from the processing of voltage and current values. The solar panel is used as a source of electrical energy from sunlight stored in batteries. This tool also has a touch screen display connected to Raspberry Pi 3 to display solar panel data (voltage, current, power, and absorption efficiency) in numeric form and manage measurement data (intervals and data quantity) based on GUI (Graphical User Interfaces). The measurements of voltage, current, electric power, and the efficiency of solar panel yield an average error below 4%. The results of measurement data monitoring are displayed in graphical form through ThingSpeak cloud server that can be accessed via a smartphone and PC (Personal Computer).

This study is meant to assess the groundwater and surface water of Lashkergah City; in this study, drinking water pollution in terms of Heavy metal pollution index (HPI) and Correlation analysis performed. The water samples collected from five wells and one sample from surface water during the autumn season (October 2014). The concentration of metals like (Cr, Mn, Fe, Ni, Cu, Zn, Cd, Hg, Pb, and As) was tested and determined by Inductivity Coupled Plasma Mass Spectrometry (ICPMS). For analyzing the standard data methods, the HPI model, and resultant data utilized. Drinking water samples (n = 6), the highest value of heavy metal pollution index HPI = 96.82 has been recorded from the Lashkergah city area. Correlation analysis data showed that the sources of heavy metals in surface and groundwater analyzed between metals such as; Chromium positively correlated with Hg (r = 0.725801) and negative with other heavy metals. Mn has strongly positive correlation with Fe (r = 0.988553) and Arsenic (r = 0.909246), but some correlation with Nickle (r = 0.737467), Zinc (r = 0.664663) and Pb (r = 0.415797). And negative values with Cu, Cd, and Hg. A negative correlation means there is some difference between source amounts of metals. Still, a positive correlation shows that it obtained from the same amount of solid wastes and air pollutants in the study area. Wells and surface water metal-containing concentration is different, because surface water is directly contacted with wastes, air pollutants and used minerals than wells water, so it has less amount of heavy metals. Heavy metals like Cd, Hg, Pb, and As have bad impacts, and some of them are hazardous to all living things, especially to Human beings.

The movement of atmospheric particles, which decreases contrast, changes color as well as atmospheric particles difficult to identify by human vision as well as some outdoor computer vision devices, will be used in images captured in hazy or foggy weather conditions. Image dehazing is thus an important issue and has been widely explored in computer vision. The task of image dehazing is to remove weather factors' impact to enhance the image's visual effects and to gain post-processing. We were using a pre-method of dark channels to dehaze images and NPEA to increase the image's naturalness or edge detection to detect edges.

Cloud computing is a cutting-edge technology that has been recognised by the organisations and individuals for a wide range of potential applications. Software-as-a-Service (SaaS), one of the cloud computing models, is a service which is provided at the topmost service layer, that receives computing resources and services from external providers and allow the remote use of business applications. Since the first appearance of the concept, few researches are dedicated to determining the drivers and complexities of adopting SaaS cloud computing services thus, the literature is limited on this topic. As more adopters are becoming familiar with the technology and implementing cloud computing in their business work, understanding what determines adoption decisions is essential for future cloud technologies to be aligned with the consumer's needs. In this study, a research model is introduced based on the technology-organization-environment (TOE) framework to assess the determinants that influence the adoption of SaaS cloud computing services. This paper primarily aims to present the concept of SaaS service model and to critically evaluate the drivers and complexities for adopting SaaS cloud services. The results of the study will provide practical strategies not only for the organisations considering the adoption of SaaS cloud services, but also for the vendors supplying SaaS services.

The function of customer service includes serving customer complaints. The process is able to use as a control for customer satisfaction. The more consumers who are satisfied with the benefit of a product, the better the customer service will be. Currently, Chatbot has been widely used in companies to improve service and to simplify customer service. Its existence is beneficial in facilitating fast data access so that it can provide services to customers more quickly. Because of this easy access, companies are obliged to ensure that all devices they have are guaranteed security. Based on this reason, the researcher will increase the Security Framework on the Chatbot by using MAC address authentication which can only be accessed by the registered customer's hardware machine address, so that if it is accessed on a different hardware device (smartphone, laptop or tablet), then the chatbot menu will not be able to be run. MAC address authentication on hardware is expected to be the first stage to be authenticated by the system prior to software authentication such as hybrids such as matching name and password, unique code and email verification.

In Digital Communication System, the requirement of high-speed data transmission achieved through the channel is most important. But in transmission, the data flow rate is reduced due to the Inter Symbol Interference (ISI). For removing this ISI, we require a Channel equalizer. In this paper, we used the Least Mean Square (LMS) equalizer technique. LMS technique shows the convergence of weights with sampling instant and also compare the eye diagram before and after the adaptive equalizer. The adaptive LMS equalizer reduced the ISI and gives better performance.

Systems of linear equations appear in many areas either directly as in modeling physical situations or indirectly as in the numerical solutions of other mathematical models. The solution of the linear equations’ system is probably the most important issue in numerical methods like the finite element method (FEM). Using the finite element method in modeling various structures, with either simple or complicated configuration of elements, in structural engineering became prevalent many years ago. There are two main types of solvers depending on whether the used method is direct or iterative (indirect) method. In contrast to the iterative techniques, the direct techniques provide almost exact solutions, however they are not convenient for some situations, including but not limited to huge systems of equations. In such situations, the iterative solvers are favored as they have privileges concerning solving speed and storage requirements. In addition, indirect solvers are simpler to program. This research focuses on using the Classical (Stationary) iterative techniques for solving linear systems of equations. The main objective of this research is to develop a new modified version of the well-known Gauss-Seidel (GS) iterative technique which is adapted to solving problems in structural engineering. The proposed technique remarkably outperforms GS technique regarding the required number of iterations and the convergence speed. In this paper, the differences between the direct and iterative approaches have been discussed, along with a quick overview of some of the methods underlying these two classes. Then, the idea and algorithm of the new proposed “Modified Gauss-Seidel” (MGS) technique have been elucidated. Afterward, the algorithm has been programmed and used to solve some 2D Practical Examples, besides using the conventional Jacobi and GS techniques. Finally, the obtained results have been compared to assess the proposed MGS; it outperformed both Jacobi and GS.

This research aims to discuss ‘generation gap’ as a matter of emotional distance, as portrayed in the novel Hatimu Aisyah by Zurinah Hassan. The term ‘generation gap’ is usually associated with the difference in beliefs, thoughts, values and tastes of two different generations, particularly between the old generations and the younger ones. The differences thus cause difficulties in communication, inflict conflicts, and furthermore, may initiate emotional distance between the two generations. The research outlines three objectives to achieve, (1) to identify the characters conflicting with the issues of generation gaps in Hatimu Aisyah by Zurinah Hassan; (2) to classify causes of conflicts pertaining the issues of generation gaps in Hatimu Aisyah by Zurinah Hassan, and (3) to relate the issues of generation gap with social changes in Hatimu Aisyah by Zurinah Hassan. This research employs close reading method. The primary source is the novel Hatimu Aisyah by Zurinah Hassan, first published by Dewan Bahasa dan Pustaka in 1991. The secondary sources include journals, books, articles, references or other sources that enable further understanding on the issues highlighted in the primary source. To clarify further on the issues of generation gaps, the research also employs the theory of Psychosocial Stages of Development by Eric H. Erikson. Erikson outlines eight confronting stages in one’s life, namely (1) infant (basic trust vs basic mistrust), (2) toddler (autonomy vs shame & doubt), (3) preschooler (initiative vs guilt), (4) school-ager (industry vs inferiority), (5) adolescent (identity vs role confusion), (6) young adult (intimacy vs isolation), (7) middle age (generativity vs stagnation) and (8) older adult (ego-integrity vs despair). The results later indicate that there are four groups of people conflicting with the issues of generation gaps, each represented by Aisyah’s mother (grandmother), Aisyah (mother), Jamilah, Latifah, Hamid, Aziz and Rohani (sons and daughters) and Azizah, Rodiah and Anisah (granddaughters). The causes of conflicts are due to perception of these generations on (1) the types of education they received, (2) the influence of modernization and (3) the decline of traditional customs. It is later clear that the more the younger generations accustomed to the social changes, the wider the gap would be expanded, thus the more possibilities emotional distance occur among the older generations who are still bound to the inheritance.

Due to the scarcity of energy resources and the high cost of production and transmission, human beings are always looking to optimize energy consumption so that they can pay the lowest cost while using all the tools that need to consume energy. Consumption optimization is not only economically beneficial to the consumer but also beneficial to production units and the environment. Equipping residential buildings with smart equipment is a solution to this problem, the implementation of which can be costly at first, but in the long run can reduce many economic costs and environmental pollution. Smart control systems have high flexibility and can be easily adapted to different needs. The smart management system, using the latest technologies, is the percentage that creates ideal conditions, along with optimal energy consumption in buildings. Therefore, in this paper these systems examined, and we have tried to examine how to control and reduce electrical energy. In this regard, two optimization algorithms have been used to reduce energy costs, the results of which have been compared with each other. There is now a smart control tool that allows the consumer to schedule their home appliances on a daily or weekly basis while using them to pay less for non-peak times. Energy hub is a concept that has recently been introduced in energy systems integrated with multiple energy carriers. Specifically, it is the central energy hub in which all the activities related to a system, including production, storage and energy consumption in the application equipment are determined. In this paper, the YALMIP toolbox of MATLAB software is used in energy efficiency optimization with the aim of reducing the costs of fossil fuels by considering the production capacity of a photovoltaic production unit. With this toolbox, the right time to turn on each of the appliances is determined according to the practical limitations of each of them, and the most possible use is made of the photovoltaic unit that produces clean energy.

A workload adjustment is an important factor in any type of work. Adjustment of physical workload must be maintained in balance to make employees not burnt out by excessive workload when carrying out their activities. Excessive workload can lead to decreased work productivity, work motivation, work injuries, and reduced concentration. This service company is one of the state companies run in shipping and logistics services businesses. It must be able to control the workload to make it appropriate for its employees. The service company owns many subsidiaries throughout Indonesia, although difficult to evaluate, this company must be able to balance the physical workload in its entire company. One example from the branch of Malang Raya showed an unbalanced physical workload. Therefore it is necessary to measure the workload in this study by applying the Cardiovascular Load (CVL) Method. This method is used by several previous studies to measure the physical workloads. The measurement instrument to gauge the physical workload is an oximeter. Participants in this study were the employees with a total amount of 30 people. It conveys an average result of 40.75 % from 30 employees taken of the branch of Malang Raya. This result measurement categorized as high classification of workload so that improvements are needed to help in balancing the physical workload which experienced by most of its employees. From the workload measurement, this service company should consider the evenly distributed tasks or workloads over each employee in this company, especially for those who have experienced physical overload. In addition, it is necessary to consider additional employees at branches of service companies whose working conditions had reached the workload limit. As for the next researcher, it can be analyzed to see the mental workload and employee needs for each branch of this service company.

Smartphones have become an inseparable part of every individual globally and the users have become increasingly dependent on these multi-functional gadgets that help in our day-to-day activities. But a user never knows what is going on inside his phone. He cannot decipher seeing a mobile application, whether it has any malicious behaviour by its appearance for any downloaded application from play store, or any third-party store. That app may be transmitting your data to a remote server without your knowledge. Even Google play store sometimes cannot detect these applications due to code obfuscation techniques. This research analyses mobile sensors' behaviour in malicious and benign mode and tries to detect if any application performs any malicious activity. Sherlock dataset has been used for the behavioural analysis by applying four supervised machine learning techniques to detect unusual behaviour and comparison has been made. We have taken two feature sets, one containing only application features, and others containing global features along with application features. We have used the F1 score as a deciding parameter for the best performance. XGBoost performs best with an F1 score of 98.82% and 98.86% on applications dataset and global dataset, respectively.

Biodiesel seems to be an energy that has bright prospects and future, because Biodiesel is non-toxic, biodegradable, essentialy free of sulfur and carcinogenic benzene, produced from renewable materials, recyclable sources, does not add significantly to the accumulation of greenhouse gases. In general, biodiesel is made from transesterification reactions, i.e. alcohol reactions with triglycerides form methyl esters and glycerol with the help of base catalysts. In the manufacture of biodiesel, crude palm oil (CPO) raw materials are obtained from PT. Sinar Mas Sejahtera in Prabumulih, South Sumatra. This research was conducted by reacting the comparison ratio of CPO: Methanol (in this study the ratio is 1: 2, 1 : 3 and 1 : 4) with the help of NaOH catalysts (in this study catalysts used 1%, 1.5% and 2%) temperature of 70oC for ±3 hours. Through this experiment, biodiesel yield was obtained at cpo variation 1: 4 with NaOH catalyst of 1.5% by 70%. The final results of this study, from CPO and Methanol varying can be concluded that not all parameters correspond to SNI where the density obtained is 0.8387 while SNI (0.850 – 0.890 gr/ml). For viscosity it meets the standard of 4.8 – 5.5 cSt with SNI (2.3 – 6.0 cSt).

In India, all Tier -1 cities have METRO Rail and/or BRTS as a mass rapid transport system. Very few tier-2 cities have MRTS and currently they are depending on city bus service for public transportation needs. Even public transportation in these cities is depleting and expenditure is increasing. For providing more service to people and coverage area each year system expansion is done and basic cost is not recovered by operating the Transit service from normal fare (direct income). For this subsidy is given to ULB. In many case the indirect income is more than the direct income. For this improving the level of service is important to maintain and/ or improve the transit ridership. MoUD has developed the service level benchmark in 2008 based on expert’s opinion. In that quantitative criteria are based on the performance of the transit system and qualitative criteria are not consider. Also the users’ and operators’ perspective may differ from the expert opinion. Hence it’s required to measure the transit service attribute based on users’ perspective to know the actual demand/ exaptation from the people. Operators are driving the transit service based on the revenue generation and because of this they neglecting to enhance the important service attribute. Also it’s important to consider the operators’ requirement to maintain the transit service. Therefore, improving existing service levels of public transport systems is required, in order to counter the challenges of rising trends of private vehicle ownership and environmental pollution. Improved level of service for public transit will improve user perception (i.e, customer satisfaction) of existing transit service quality amongst captive riders, choice riders and potential transit riders.

The accuracy and smoothness of the husk fuel feed in a fixed bed combustion furnace is very important in improving the performance of the husk combustion. In this study, a screw feeder was designed to feed rice husks into the combustion chamber, according to combustion requirements smoothly. The feeding mechanism used is that the husk from the hopper is fed into a screw feeder which is rotated by an electric motor. The husk feeding rate can be regulated by controlling the rotational speed of the electric motor using an inverter. For smooth feeding, a tapered outer diameter screw was used with the screw outer diameter enlarging from 48 mm at the inlet to 69 mm at the outlet. The husk feeding performance was tested in: 1) the non-combustion conditions and 2) the combustion conditions in a fixed bed furnace. The results of the performance test without combustion showed that the feed rate of the husk increased linearly with the increasing of the screw rotating speed. The husk feeding rate at 10-35 rpm screw rotating speed was 2.85-10.91 g/s. In the combustion test, the screw feeder could feed the husks to the combustion chamber smoothly. The temperature of the combustion chamber increased as the husk feed increases. There was no significant increase in temperature in the screw feeder and no burning of husks in the screw feeder.

Recommendation systems are an integral part of information filtering system in data science, that are widely used in order to identify the pattern a user would likely choose on the basis of the previous choices of the user as well as from studying the pattern in which others have chosen. For a fact, the recommendation can never be a cent percent correct at providing recommendations to the user but can be close enough to please them to a certain extent. Thus, the same is widely used in the industries these days to get higher profit and have a good hold in the market. The data scientists of every company design some algorithm that studies the information from the social network and clusters the data. There can be a single algorithm for classification like k-Means clustering or Hidden Markov model or can be done by bagging and boosting techniques. With this technique of displaying the movies or products into the profile of a particular customer, they not only increase their business but also enhances the customer experiences but there are several issues related to the standard techniques like the cold start problem, shrill attack, etc. thereby increasing the scope of research in this field. This work deals with both Collaborative Filtering and Content-Based Filtering to form a product and movie recommendation system for the social networking sites that shows the effectiveness of collaborative filtering and portrays the challenges faced by content-based filtering.

Biomass is the world’s most commonly used source of renewable electricity today. It is used primarily in strong form and, to a smaller degree, oil fuels or petrol. In contemporary times, the use of biomass for energy generation has risen at only a small pace. Biomass is the primary source of energy in Indonesia. Biomass is used to fulfil a range of energy requirements, including producing electricity, heating households, fueling cars and supplying industrial equipment with a heat process. Biomass potential includes waste from timber, animals and plants. Among biomass power sources, fuelwood might be the most important since it accounts for a large 17% share of Indonesia total power manufacturing. The complete biomass energy potential in Indonesia is about 38 million tons of oil equivalents (Mtoe). The quantity of biomass that can be used in Indonesia is roughly 32 Mtoe. The potential for electrical manufacturing from usable bioenergy sources in 2012 is 83 MW and corporate revenue, representing more than 350,000 jobs. This research shows that the potential for climate change mitigation and power sustainability in Indonesia is significant for biomass energy.

The development of inter-city road infrastructure development in Indonesia has already increased sharply along with economic growth and regional development. The geometrical design of the road has already been designed by the standard provisions and needs of the functions of the road services built. The application of physics concept in designing geometrical platform as a function in applying theoretical physics to the standardized-geometrical design. A centrifugal force in the physics concept is a basic principle in designing geometric horizontal alignments of the road. Conceptual understanding of engineering students in term of designing geometrical design perspective, has been based on the implementation of centrifugal force in the case of work on vehicles ride in the road bends. The implementation has ever been based on variables which were determined by understanding to apply logic of thinking constructively. The variables are determining the students‘ conceptual understanding on the parameters of the centrifugal force equation which is working on the bend. The analytical method which is regarded on the categories of parameter functions used, is the approach of implementing centrifugal force. Civil engineering students‘ conceptual understanding on geometrical designs through the implementation of centrifugal forces are able to increase the ability of analyzing process on the functions of comfort and driving safety. These procedures are collocating with reducing the effect of greater centrifugal force. Moreover, the application is also able to reduce accident-prone areas due to the influence of magnitude-centrifugal forces on the geometrical design of the road.

This study mainly focuses on synthesis of AA6061 composites reinforced with granite particles using stir casting technique. The microstructure of Al6061 alloy and Al6061-granite composites were studied using scanning electron microscope. Friction and wear behavior of Al6061 alloy and Al6061-granite composite were evaluated under varied loads and sliding velocities using tribometer in accordance with ASTM-G99 standard. SEM of composites reveals that distribution of granite particles is homogenous in matrix material. Friction and wear tests demonstrate addition of granite particles in Al6061 alloy has led to fall in wear rate and friction coefficient. Rise in the applied load enhances the wear rate and drops the friction coefficient for all the combinations studied. Increase in sliding speed increases both friction coefficient and wear rate. However, at all the loads and sliding speed, Al6061-granite composite displayed lowest wear rate and friction coefficient.
