Combustion of coal and co-combustion of their co-fuel contribute to gas emissions. Among the gas emissions are SOx, NOx, CO and CO2. Introduction of calcium based adsorbent is addressed to absorb SO2 that release to the atmosphere during the combustion process. Objective of the research is at first to observe the physical characteristics of biobriquettes as a function of briquette compositions (coal to palm kernel shell ratios) and Ca/S ratios (Ca in adsorbent and S in briquette) using a natural adsorbent (shellfish waste). The second objective is to investigate desulfurization characteristics as a function of Ca/S ratios and desulfurization temperatures at coal to palm kernel shell ratio of 90:10 (wt %). Ratios of coal to palm kernel shell in this study are 90:10, 80:20, 70:30, 60:40 and 50:50; and Ca/S ratios are 1:1, 1.25:1, 1.5:1, 1.75:1 and 2:1. Binding agent used is the mixture of Jatropha curcas seeds and starch as much as 10% (wt). It was found that introducing the palm kernel shell and adsorbents in the coal briquette affect the water resistant and compressive strength. The highest water resistance and compressive strength were 5,165 second and 34 kg/cm2, respectively. The lowest SO2 level found in this study was 1 ppm for all Ca/S ratios, except for 1:1.

Empty Fruit Bunch (EFB) as a solid waste in Crude Palm Oil (CPO) industry does not utilized yet as an alternative energy source to generate electricity. It is well known that use of solid wate (biomass) as an energy source is part of the Clean Development Mechanism (CDM) scheme due to direct reduction of Green House Gases (GHGs) emission and provide a direct contribution to sustainable development. Utilization of EFB as a source of energy is very potential to be implemented in Aceh since this province has 25 CPO Mills at the moment which actively produce about 870,000 ton EFB per year. This study is subjected to evaluate the potency of electricity from EFB theoretically by using primary data (survey data) and secondary data. Potency of EFB and number of electricity produced from that EFB are estimated using primary data and direct combustion scenario, respectively. Calculation methods for emission reduction acieved are done by AMS-I.D: Renewable electricity generation to the grid and AMS-III.E: Methane emissions avoided from dumping at a solid waste disposal site. The result of this investigation shows that energy consumption in 25 CPO Mills is 45 GW(e)h per year. Evidently, the number of energy/electricity which is potential to be produced by using 75% EFB is 1,047 GWh per year; so that the GHGs emission reduction up to 171,232.21 tCO2e per year.

Calcium oxide-based material is available abundantly and naturally. A potential resource of that material comes from marine mollusk shell such as clams, scallops, mussels, oysters, winkles and nerites. The CaO-based material has exhibited a good performance as the desulfurizer or adsorbent in coal combustion in order to reduce SO2 emission. In this study, pulverized green mussel shell, without calcination, was utilized as the desulfurizer in the briquette produced from a mixture of low rank coal and palm kernel shell (PKS), also known as bio-briquette. The ratio of coal to PKS in the briquette was 90:10 (wt/wt). The influence of green mussel shell contents and combustion temperature were examined to prove the possible use of that material as a desulfurizer. The ratio of Ca to S (Ca = calcium content in desulfurizer; S = sulfur content in briquette) were fixed at 1:1, 1.25:1, 1.5:1, 1.75:1, and 2:1 (mole/mole). The burning (or desulfurization) temperature range was 300-500 °C; the reaction time was 720 seconds and the air flow rate was 1.2 L/min. The results showed that green mussel shell can be introduced as a desulfurizer in coal briquette or bio-briquette combustions. The desulfurization process using that desulfurizer exhibited the first order reaction and the highest average efficiency of 84.5%.

The purpose of this research is to find out how the content mastery service of SMA Muhammadiyah 09 Kualuh Hulu helps students become more interested in learning. Students' study habits are developed due to this learning, and if they already have good study habits, they must be maintained. This research uses qualitative methods with a Case Study approach. The sample of this study consisted of 36 students of SMA Muhammadiyah 09 Kualuh Hulu. The data collection instruments of this research are in-depth interviews and observation. The data analysis technique used is data reduction; data reduction is a thinking process that requires a depth of insight; after reducing the data, the data is described, or what is often called data presentation; after the data is processed properly, the researcher concludes. The data validity test technique in this study uses triangulation by asking the same thing with different sources. The results showed that the content mastery services provided positively impacted students' interest in learning. This result is supported by the assessment given to students in the written test group every time they complete the material mastery activities and observed by the observation that students often lose focus in learning and often do not write school notes when learning takes place and after the implementation of student access to content mastery services it is increasingly clear that the increase in learning interest is growing towards students.
