Abstract

Gas Production Generated from Crude Oil Biodegradation: Preliminary Study on its Aplication in Microbial Enhanced Oil Recovery (MEOR). The objective of this study is to observe the capacity of gas production generated from crude oil degradation by the isolated bacteria. The gas in the MEOR could increase pressure in the reservoir, decrease oil viscosity, increase oil permeability-due to the increase of the porosity and viscosity, and also increase oil volume due to the amount of dissolved gas. A research on gas analysis of oil degradation by 6 isolated bacteria has been conducted. The bacteria isolates including Bacillus badius (A), Bacillus circulans (B), Bacillus coagulans (C), Bacillus firmus (D), Pasteurella avium (E) and Streptobacillus moniliformis (F). The trial on gas production, gas analysis and oil degradation analysis, was carried out by using SMSS medium. The test of gas production was done by using microrespirometer at 40°C. The result shows that B, C, D, E produce more gas than A and F. Gas of CO2, O2, CO, N2, CH4, and H2 were analyzed by using GC. The results show that only three gases were detected by GC i.e. CO2, N2, and O2. The concentration of CO2 and N2 gas increased while the concentration of O2 decreased over an 8th day of observation. CO2 gas producted by mix culture was higher than by the pure culture. On the 8th day of incubation, the production of CO2 gas by mix culture was 4,0452% while pure culture C and D only produced 2,4543% and 2,8729%. The mix culture increase simple hydrocarbon by 12.03% and the formation of a complex hydrocarbon by 3.07%. The mix culture (C-D) generated the highest concentration of CO2 gas as well as a synergistic concortium that has ability to degrade crude oil.

Abstract

This study aims to determine the needs of students for android-based learning media in social studies. This research method is quantitative with research subjects homeroom and class IVB students at SDN Pabuaran 1 Tangerang. The instruments used in this study were a questionnaire and a structured interview. Based on the results of interviews with teachers, it shows that teachers have never designed android-based learning media. Meanwhile, based on the results of student needs, it shows that 100% of students use Android smartphones, 61.9% use them every day (morning, afternoon, and evening), but it is unfortunate that 45% use it to watch YouTube and only 10% of students use it to study. Meanwhile, based on the subjects of interest, it was shown that 47.6% Indonesian, 19% Natural Studies, 19% Mathematics, and 0% Social Studies. In addition, 95.2% of students agree with the development of android applications. Based on the results of these studies, it can be concluded that it is necessary to consider android-based learning media in social studies in elementary schools.

Abstract

Supervision is carried out as an effort by people in authority in the world of education to supervise everything done by people related to the world of education, be it teachers, students, and so on. This paper aims to discuss the effectiveness of the implementation of supervision, with the method used is a literature review or literature study that contains theories relevant to the problems to be discussed, and the study describes the concepts and theories used based on the available literature, from books and articles that have been published in scientific journals. Supervision is carried out to find out what happens in an educational institution, such as if there is an inequality or problem in an educational institution, and the best way will be found to overcome the problem. This is an example of one of the importance of supervision. The effectiveness of the implementation of supervision will be carried out if it has gone through the planning stage, which, of course, has been mutually agreed upon by the people in charge in the world of education, so supervision is carried out in a directed and measurable manner by the agreed provisions to achieve the goals that have been expected together.
