The need for man and his interest in conditioning is due to ancient times. for example, ancients enjoyed drinking cold water without having any kind of ice in their countries by putting water in pottery vessels and leave them on the roofs of their houses at sunset and long nights, Dry desert air vaporizes the water that passes through the pores of pottery vessels and the water inside it becomes cold. The Romans and the Greeks used their slaves to bring the snow from the mountain tops and then store it in huge conical pits in the ground, lined with leaves and covered to use it when needed. Also the great Alexander used this natural ice to cool wine barrels that he offered to his soldiers in every battle they won. Emperor Nero was always offering chilled food at his concerts. Hundreds of slaves were used to store the natural ice in the vaults of his palace. People continued to use natural ice only as a way to cool their drinks for a long time.

The blended amine viscosities of N-Methyldiethanolamine and monoethanolamine (MDEA+MEA) are measured for temperature range from 293.15 to 413.15 K. The total amine strength in the solution is maintained at 0.2, 0.3 and 0.4 mass basis. Temperature range 293.15 to 303.15 K is performed with cooling system to achieve the lower stable temperatures during the experiment. Operating pressure is maintained at 1 bar for temperature range 293.15 to 353.15 K and 4.5 bar for higher temperatures. Measured viscosity data is compared with available literature data as well as with modeled data by Grunberg and Nissan model. Earlier viscosity values are available up to 353.15 K for some blended amine concentrations. Therefore, this study is given highly importance for gas absorption process while developing regression models for reacting systems in gas separation. The average absolute deviation between measured viscosity values and viscosity calculated by regression model is around 2.1%.

People who work will face a variety of stressful situations and pressures. Stress experienced by workers can be caused by various factors, generally caused by external factors and internal factors of the individual itself. Existing studies tend to focus on the influence of external factors on stress conditions experienced by workers, such as environment and work situation. Meanwhile, studies focusing on internal factors as a cause of worker stress, are still not widely practiced, particularly with regard to experience patterns and work-related behavior. Measurements used to measure experience patterns and work-related behavior are also newly adapted in some countries, using the AVEM test. Considering benefits from measuring individual experience patterns and work related behavior through the AVEM test, researchers are interested in adapting AVEM tests into Bahasa Indonesia. Respondents in this study were 357 respondents, with various educational and work background. The data were collected at various locations in Yogyakarta Province. Main instrument used in this study is a work-related behavior and experience patterns test known as Arbeitsbezogenes Vehaltens-Und Erlebensmuster (AVEM Test). In addition, this study also used other measurements to be correlated as part of instruments validation, namely Sense of Coherence Scale (SOC), Parental Stress Scale (PSS), and Family Hardiness Index (FHI). Based on results and discussion, it can be concluded that AVEM test in Bahasa Indonesia and among Indonesian produce items on AVEM test is divided into 2 main dimensions, namely Engagement dimension and Resilience dimension. Meanwhile, Emotion dimension that exists as its own dimension on English version of AVEM test goes into Engagement dimension. And referring to the results of reliability estimates, it can be concluded that Indonesia version of AVEM test is reliable for use on Indonesian. In addition, referring to the results of previous analysis, it can be concluded that Indonesia version of AVEM test can be used as a tool to measure experience patterns and work-related behavior among people of Indonesia.

This study aimed to improve the quality of blackwater by using a physical model consisting of 2 processes; stratified filters and wetland. The stratified filtration method utilized gravel, charcoal, and sand as the filter materials, meanwhile, the wetland system utilized the Cattail plant (Typha Angustifolia). Blackwater quality improvement was observed at the intervals of 2 days, 4 days and 6 days, and included parameters of pH, temperature, TSS, TDS, BOD and COD. The method of data analysis was Multiple Linear Regression. Generally, the final result showed that the blackwater quality was improved and met the standard of grade IV water quality (water for agricultural purposes). Furthermore, the equation of Regression analysis obtained was, Water Quality (Y) = 4.693 - 0.176 X1 * - 0.294 X2 * + e6 (X1 = sand thickness, X2 = residence time). This means that every 1 cm thickness of the sand layer contributes to the improvement of water quality by 0.176. In addition, each application of 1 day residence time in the wetland tube has the potential to increase the water quality by 0.294 units. Therefore, the use of filter materials and Cattail plants has been proven to be effective for pollutant removal in blackwater.

Text summarization is a process of summarize any text or document. There are many summarization tools for English language. There are also a few works for automated Bengali text or document summarization. The tools are seemed not much appropriate from application point of view. Summarization is categorized in two ways: extractive and abstractive approach. Most of the summarizer methods for Bengali text summarization are extractive. Those proposed methods can’t extract whole theme of a text document. Reader can be satisfied about summary if it gives full important information of input document. Our proposed method introduces an enhanced summarization method that can improved the quality of outputs. The proposed method is modeled combining a set mathematical rules and Bengali grammatical rules. This method also solves many problems of extractive summarizer and it also introduces the path of abstractive summarization methods. Although the method has been developed for Bengali language, it is a generic and platform independent approach and can flexible be extended for other languages.

Companies will make disclosures in excess of minimum disclosure obligations if they feel such disclosures will reduce their capital costs or if they do not want to miss competitive disclosure practices.Quality in decision making is influenced by the quality of disclosure provided through the annual report so that the information must be accompanied by adequate disclosure. Mandatory disclosure of information required by applicable regulations, in this case the regulation is issued by the financial services authority. Whereas voluntary disclosure is disclosure of information carried out voluntarily by the company without being required by applicable regulations or disclosures that are more than required.

These Wind turbines are media used to convert wind energy into electrical energy. Counter Rotating type Wind Turbine is a type of wind turbine that has a double rotor. This type of wind turbine was developed because it is very suitable for high-speed wind, in this study the length of the blade is 1.5 m. Therefore the counter-rotating type wind turbine is made with full scale and tested with the wind in nature, especially the coastal area so that it can be seen the counter-rotating type wind turbine performance when using the natural wind in Indonesia. This performance is known by measuring the amount of electric power, torque and radial speed of the front and rear rotors based on high wind speeds. In the end, the performance of the wind turbine can be known at wind speeds of more than 5 m / s where the higher the wind speed the greater the front and rear rotor radial speed. This is directly proportional to the electrical power produced and inversely proportional to torque, where the greater the speed of the second radial rotor, the smaller the torque produced. Based on data obtained at wind speeds of 5.01 m / s, the front and rear radial speeds of the motor are 25 rpm, 12 Nm Torque, and 0.0072 Watt electric power respectively. Whereas the wind speed of 8.17 m / s obtained the values of front and rear radial speeds of 428 rpm, the torque and also electric power respectively 0.700934 Nm and 4.7034 watts.

Molasses is a by-product of the sugar processing industry. Each year, molasses are produced in large quantities. Therefore, there is necessity for further treating molasses in order to have economical values. One of the utilization efforts is by using molasses as a substrate in fermentation process of citric acid manufacture. The purpose of this study is to determine the effect of fermentation time on the production of citric acid. The variables used were fermentation time of 3, 6, 9, 12, 15, and 18 days. Molasses of 250 ml were incorporated into a fermentor with 500 ml of nutrient solution and 16 ml of Aspergillus Niger. Fermentation is carried out under aerobic conditions. The concentration of citric acid from the result of fermentation was then analyzed by using gas chromatography. From the result of analysis, the best result of citric acid was obtained at fermentation time of 9 days as much as 72.3958 g/L.
