One of the technologies that can be used to meet energy needs is biomass combustion. In this study, the oil palm biomass fuels used were empty fruit bunches, oil palm fibers, oil palm midribs, and palm kernel shells. This research was carried out by a direct combustion method using a fluidized-bed combustor. The purpose of this experiment was to investigate the reaction of kinetics and the mechanism of combustion of oilpalm biomass in fluidized-bed combustor. The characteristics observed in this test were the combustion temperature profile, flue-gas composition, and the composition of the ash-deposit chemical compound. The results of the experiments conducted showed that the best biomass combustion temperature profile was recorded at 2 kg biomass with an air flow rate of 0.9375 m 3 /s at 90.1%. The maximum temperature of biomass combustion recorded at biomass 3 kg with an air flow rate of 1.25 m 3 /s are 950 o C (95%). The higher conversion combustion of biomass was found at biomass condition of 3 kg with an air flow rate of 0.9375 m 3 /s. The value of O2 emissions from biomass combustion shows that it was very small 0.2%. While the highest CO2 value was recorded at 19.9%. The highest combustion efficiency on FBC found 1 kg of biomass fuel with an air flow rate of 0.0654 m 3 /s recorded 94.9%.

This is a community service related to the development of economic community through socialization on muamalah principle and the prohibition of maghrib (maysir, gharar and riba) in the daily transaction. Nowadays, some people in Indonesia have begun to care about the dangers of riba and its impact on the economy. Muslims have believed that riba is haram. Some of them certainly can define as well as interpret the term of riba, but not for maysir and gharar. According to the perspective, Islam always encourages the practice of good muamalah principle and forbids maghrib. Ironically, there are still many ordinary people do not understand the general rules of maghrib. In returning the daily transaction to avoid maghrib, it is necessary to learn deeply about this subject. For this reason, there is a need for socialization to the wider community to increase good understanding of the maghrib and get literacy about sharia transaction well and certainly can be implemented in the daily transaction of community in Indonesia.

The Sustainable Development Goals have become the UN's global goals in the 2015 to 2030 time frame. To achieve these goals, Indonesia has designated a National Roadmap for Sustainable Development Goals in Presidential Regulation Number 59 of 2017. The Presidential Regulation serves as a guideline for Ministries or Agencies in National Actions Plans on Sustainable Development Goals in their respective domains. Including in the Public Procurement of Goods/Services has been fostered to increase sustainable procurement. This Systematic Literature Review has been looking for research evidence to reveal the contribution of e-procurement in the Sustainable Development Goals in Indonesia for the last decade. The evidence has been systematically collected by following the SLR protocol from the indexing Portal Garuda (Garba Rujukan Digital) specific for published articles in Indonesia. Meanwhile, the international research on sustainable procurement has been ongoing since 2001; the review here shows that there has not been much research on sustainable procurement in Indonesia. The results of this review offer a future research agenda for sustainable procurement in Indonesia.

Investigation of combustion temperature through experiments with a wide range of fuels, both solid and liquid, is continuously being conducted by scientists around the world, while the measurement of heat transfer rate can be analyzed when the combustion process occurs. Previous research has generally been conducted using liquefied gas, fossil fuels, and alcohol additives. Specifically, the research in this work investigated the convection heat rate and combustion temperature through the modification of the perforated plate. The experiment was conducted in the fluidized-bed combustor (FBC) fuel chamber using solid waste fuel of oil palm biomass. Measurements were performed at four different points using the HotTemp HT-306 Digital Thermometer. The results of the experiment showed that the convection heat rate in measurement one (M-I) reached 8.258 W/m2 for palm kernel shell (PKS) fuel. Meanwhile, in measurement two (M-II), the convection rate of 7.392 W/m2 was produced by oil palm midrib (OPM) fuel. The highest combustion temperature was recorded with OPM fuel (884°C) at M-I. However, the combustion temperature of the PKS combustion process is higher at 896°C but shows a less good trend than OPM. Overall, the measurement results of the three types of fuel used to modify the perforated plate applied in the FBC fuel chamber are excellent. It can be proven that the fuel is put into the combustion chamber with nothing left.
