Efforts that can be made to limit nutrient losses and restore fertility of yan is by recycling organic waste such as crop residues, crop residues or residual crop residues even from weed plants.The result of recycling of organic waste is returned to the land either directly or after being processed into compost or fermented.This type of fertilizer serves as a benefactor of nutrients useful for the improvement of soil structure. Many composting processes can be accelerated by the addition of activators in the form of microorganisms that can accelerate the decomposition process of organic waste. This biotivator can be derived from local microorganisms (MOL).MOL is a fermented liquid that uses locally accessible resources. One of the natural resources that can be utilized in making MOL by mixing ingredients from the golden snail, banana hump, rumen cow and fruit waste. This MOL contains bacteria of organic matter, plant growth stimulants, pest control agents, and nutrients needed by plants. This research aims to: To make bioactivator and produce compost from kirinyuh which is rich in nutrients with the help of bio-activator of local mkroorganismeThe materials used in this research are the making of MOL is banana hump, fruit waste, golden snail, cow rumen, cow urine, coconut water, rice laundry water (leri), shrimp paste, brown sugar for MOL I. whereas For MOL II only distinguished by using white sugar .. Mol is made by fermentation. After the mole, it is continued with the maker of compost fertilizer with kirinyuh plant material, bran and fertilizer. Cage Making MOL is done in Laboratoriuam Production of State Agricultural Polytechnic of Samarinda.Based on the results of physical observations of compost kirinyuh on the 10th day (10) compost has been so with the characteristics of black, smelly soil, crumb texture while the chemical analysis of nutrients on the compost kirinyuh with bioactivator mole combination at each treatment is as followsK1M2 (N 1.37%, C organic fertilizer 29.31%, C 1M1 (N 1.45%, organic C 26.17%, C / N ratio 18.01%, P2O5 0.74%, K20 0.38%, Cao 10.47%, MgO 0.19%, pH 7.14), K1M2 (N 1.37%,, organic C 29.83% Ratio C / N 21.77%, P2O5 2.40%, K20 0.98%, Cao 10.90%, MgO 0.19%, pH 7.82), K2M1 (N 1.17%, C organic 22.90%, C / N ratio 19.57, P2O5 1.83%, K20 0.34%, Cao 10.90%, MgO 0.39%, pH 7.02), K2M2 (N 0.90%, C organic 23.17%, C / N ratio 25.74, P2O5 1.27%, K20 0.24%, Cao 10.69%, MgO 0.19%, pH 7.22), K3M1 (N 1.32%, C organic 19.72%, Ratio C / N 14.94, P2O5 3.81%, K20 0.45%, Cao 12.40%, MgO 0.39%, pH 8.04), while K3M2 (N 1.33%, C organic 21.60%, Ratio C / N 16.24, P2O5 4.07%, K20 0.98%, Cao 9.83%, MgO 0.19%, pH 8.38).

In India, from June 16th onwards fuel price is fixed by the oil companies by day today basis. The price fixation is based on the crude oil prices in the international market. This study probes the revised petrol price based on the estimated GST in India for the time span of October 2, 2017 to January 31, 2018. Neural network model is trained by this data and crude prices to predict the fuel price. From February 1, 2018 to 22, 2018 the fuel price is simulated and verified with the original price. The error percentage also reveals the exactness of the model simulated. In this paper, additionally fuel price is estimated along with GST. Even though GST is not yet implemented for fuel, with 4 different percentages it was simulated. Results revealed that there is a considerable amount of decrease in the petrol price if the GST is implemented in India. This study also breaks up the taxes involved in pricing of petrol in India and shows how GST helps the end consumer in the reduction of petrol prices by cutting down the taxes like excise duty and VAT.

Five samples of limestone collected from different locations at the Okeluse forest reserve, were petro graphically studied under the microscope at x80 magnification. Samples showed shell fragments of echinoderm, brachiopods surrounded by micrite envelope which indicate a low energy environment of formation .The presence of brachiopods indicate that the Okeluse Limestone belongs to the group of rocks of ancient marine of the Palaeozoic-Mesozoic era. Mudstone matrix in some samples could have caused the greyish colouration of the Okeluse Limestone since the detritus (sand or mud) was excreted by the constituent organism. Bivalves and gastropods are identified. They are made of aragonite and preserved as casts.

Evaluation of the effect of container types and size currently used by nursery rubber growers is important to reduce the problem of dieback and causalities during transplanting of seedlings. Assessment of the planting material is essential for replanting exercise to meet its objective of early growth and optimum yield in the later stage of the plants. The study was conducted to evaluate the impact of various container sizes on the growth of rubber seedlings. Containers of different volumes 600 ml 710 ml, and 900ml and polybag 15 ◊ 20 cm as control evaluation was used. All the containers except polybag greatly support plant stem diameter. Only the biggest container 900 ml maintained higher leaf area index (LAI). Plant biomass like total fresh and dry weight and the root-shoot ratio (RSR) were significantly different in the same container. Plants grown in this container recorded higher nitrogen content which could be considered suitable for rubber seedlings. Root length of the plants was greatly influenced by the container (900 ml) and significantly higher than those in other containers. Root average diameter was positively affected except for the plants grown in the poly-bag. This suggests that the polybag and the remaining container sizes inhibited the roots and this could have contributed to the poor growth and some of the morphological traits. Consequently, a large container size, 900 ml had resulted in a better and vigorous growth of the seedlings and it could be ideal pot size for use in raising rubber seedlings of H. brasiliensis.

The research was aimed to find the configuration of an elite in an extension of Obi Islands Regency of South Halmahera - North Maluku; to map on contrastive elites of extension and interest, and of pro-group conflict of Obi Islands Regency extension. The method used in this research is a case study method by qualitative approach. The research method is the purpose to describe, record, analyze and interpret conditions occurred in the field. The research result shows that extension of Obi Islands Regency is boosted by geographical aspect. The extension plan of Obi Islands Regency causes pro and contra between inside and outside elite of Obi Islands. The contrastive elite extension is the Regent of South Halmahera (Muhammad Kasuba). It is caused that the Regent has the economic interest (business entity) in Obi Islands. The interest competition happens to the pro-group extension of the elite in Obi Islands against the elite in Ternate City. The rivalry among pro-group of extension, basically, is competition to get an influence and support from Obi's society and effort to maintain and/or take resource away in Obi Islands after the extension become the rivalry factor of proĖextension elite. The conspiracy happens because of the economic interest in pro-extension elite (Abu Karim La Tara, and Hi, Subur) against with contra-extension elite (Muhammad Kasuba as the Regent). This conspiracy is in terms of defending and securing business entity (economic interest) in Obi Islands' territory. Whereas, the elite configuration happened, in fact, is the collaboration with/between ethnicity and religion aspect. Therefore, the geographical aspect occurred is polarity among Obi elites. Polarized Obi's elites based on region either Obi Islands' territory, Labuha-Bacan and Ternate as well have mounted interest rivalry among the individual elite of Obi existed in North Maluku Province.

most vehicular application calculating a vehicle speed is very important. In this paper when GPS is not available vehicle speed is calculated by using sensor in the smartphone. Vehicle speed is estimated by calculating the accelerometer and find the acceleration error since it leads to large deviation between calculated speed and the real speed. The acceleration error can be corrected at a point called reference point. Vehicle speed is exactly known through reference point. In urban environment which includes many turn, passing through uneven roads to eliminate the acceleration error caused by estimated speed deviation and to derive reference point. Estimation error on real time in local road is 32mph and in offline is 0.75mph and the GPS average error is 3.1mph and 2.8mph.

Wastewater from small scale gold mining (SSGM) milling facility contains high amount of suspended solids and elevated concentration of Hg and other heavy metals. Most of these milling facilities have inadequately designed sedimentation tanks as its only treatment method, thus releasing wastewater to the receiving water bodies with heavy metals and suspended solids. In this study, sedimentation tests were conducted to investigate the removal of suspended solids and heavy metals (As, Hg, Pb) from actual small scale gold mining (SSGM) wastewater gathered from SSGM area in Paracale, Camarines Norte using settling column. A glass column with a diameter of 7.5 cm and a height of 120 cm was used to determine the removal rate of total suspended solids at settling time up to 720 mins. After 600 min of sedimentation, 100% removal of TSS was achieved. Heavy metal removal in the wastewater were tested at 100 cm from the bottom and results showed that after 480 min, removal efficiencies of 98.69%, 93.60% and 93.70% for As, Hg and Pb, respectively were achieved. The sediments collected from the settling column were analyzed for heavy metal concentrations and particle size distribution by atomic absorption spectrophotometer (AAS) and hydrometer, respectively. The X-ray diffraction (XRD) analysis result of the sediments indicates that the major component is silica.

Due to the high demand of the management of waste sediment from industrial port in France. The reuse of this particular material is urgently needed to realize. The stabilization is one of the methods proposed. The high content of heavy metal in this waste makes it difficult to stabilize it just only with normal hydraulic binders. Fly ash utilized in this study is a byproduct of from local coalmines. The main idea is to maximize the utilization of waste material by stabilizing waste with a waste material. The application of the reuse of the waste sediment is as material in road construction work. First step is identifying the initial characteristics of waste sediment and binders used in this study. The chemical test is implemented as well to find out the heavy metal content in the waste. The next step is formulating the ideal composition of the binders in the mixtures. In order to verify the capabilities of stabilization process (with fly ash) to meet de needs on road construction is done by realizing several geotechnical tests. The result shows that the heavy metal content of the waste sediment is categorized in a medium level (non hazardous waste). The mixture with highest strength value is not exactly with the highest content of fly ash. The water sensitivity test confirmed that the mixture without any fly ash content couldnít survive to mouillage-sechage cyclic test. . The Unconfined compressive strength and tensile test shows that the addition of fly ash clearly provides an additional performance especially at long term of curing age. The fly ash addition helps to improve the engineering properties and the result confirmed that the waste sediment stabilized with fly ash could and safe to be used as replacement material in sub base course in road pavement.

The investigations involve the analyses of high resolution aeromagnetic data and satellite imagery over parts of Nasarawa and environs. Airborne magnetic data and satellite imagery were interpreted to delineate structures and lineament pattern of the study area as potential for minerals occurrence, field work was undertaken in the study area to relate the effect of the structures in field to result obtained from the interpretation of the high resolution aeromagnetic data. The lineaments identified on both aeromagnetic map and Satellite imagery are in agreement with the main structural trend of the Benue Trough. Results from the interpretations indicate anomaly trends in the NE-SW, NW-SE, E-W, and NNE-SSW directions. The rose diagrams obtained from the magnetic residual map and the satellite imagery suggest predominantly NE-SW, NW-SE directions, the consistency in the alignment of lineaments suggests a possible genetic association of these anomalies. The occurrences of lineaments which include pegmatites, fracture, faults joints veins and fold as revealed in the quantitative analysis of the magnetic residual contour map, satellite imagery and field work excercise show the interplay of tectonic activities due to multiple deformational episodes, this study highlight magnetic lineaments as key indicators to mineral occurrence.
