Abstract

Pyrolysis is a thermo-chemical which decomposition of organic material through heating process with absent or little oxygen (anaerobic). The purposes of study are design pyrolyzer of coconut shell being to alternative fuels, knowing much of oil from pyrolysis process with method of counter flow and parallel flow, and knowing heat energy or caloric energy which was produced from pyrolysis process with method of counter flow and parallel flow in condenser. The research with through experiments the pyrolyzer which includes reactor, distribution pipe, and condenser. Research methods are the experiment of pyrolysis process at temperature 35oC during 60 minutes with condensation method, counter flow and parallel flow. Results of experiments are data of gas fuels mass obtained 42 grams which used pyrolysis process of coconut shell in the amount of 1000 gr, until produces pyrolysis oil as 198 grams (counter flow) and 196 grams (parallel flow). Counter flow method can absorb a heat as 1304,762 kJ and heat loss through gasses as 462,842 kJ, even though parallel flow no more than absorb as 1200,83 kJ and heat loss through gasses as 545,271 kJ.

Abstract

The use of plastic and goods made of plastic have been rising in day to day. Increasing use of plastics is a consequence of the development of technology, industry and population. On one hand, the invention of plastic has a remarkable positive impact, because it has many advantages compared to other materials. But on the other hand, the plastic waste has negative impact that too worried, so its solutions need to be looked for. One of the alternative handling of plastic waste that currently extensively researched and developed is converting plastic waste into fuel. Converting plastic waste into fuel oil can be done with cracking process. There are three kinds of process that is hydro cracking, thermal cracking and catalytic cracking. Fuel oil produced from the cracking of plastic waste depending on the plastic type, cracking process used, catalyst type, pyrolisis temperature and condenser temperature.

Abstract

The Nagan Raya coal-fired power plant in Aceh, Indonesia, serves as a major supplier of electricity to the region's power grid. However, the power generation unit of the plant, which supplies reactive power to the subsystem, often experiences disturbances that cause voltage values in the Banda Aceh substation system to decrease. This decrease in voltage can be detrimental to the quality of power supplied to the consumers. To address this issue, a capacitor bank with a capacity of 25 Mvar was installed at the end of 2016. The capacitor bank was successful in increasing the voltage value at the substation and proved to be an effective solution. However, with the anticipated growth in load in the coming years and the possibility of future disturbances in the power generation unit, it has been proposed that an additional capacitor bank unit with the same capacity be installed to further enhance the voltage quality at the Banda Aceh substation. To assess the feasibility of this proposal, simulations were carried out using ETAP 12.6.0 software. The simulation results show that the addition of a 25 Mvar capacitor bank unit would lead to an increase in the substation voltage value of around 5-6 KV. This increase in voltage would help to maintain the quality of power supplied to the consumers and ensure that the power grid remains stable even in the event of disturbances in the power generation unit. Overall, the proposed installation of an additional capacitor bank unit would be a cost-effective solution to enhance the voltage quality at the Banda Aceh substation and ensure the stability of the power grid. This solution could be adopted by other power plants facing similar issues in maintaining voltage quality in their power grid systems.

Abstract

In Aceh Besar, Suka Makmur and Lam Phueot villages, lotus root souvenir manufacturing faces several obstacles such as inadequate marketing strategies and lack of skill in the process. Therefore, this initiative seeks to provide partners with production-related solutions by integrating technology with Rencong souvenir molds. The implementation team also performs socialization and consulting related to internet marketing of products to increase market access and outreach. Program objectives were achieved using the Participatory Rural Assessment Act (PRA). From this initiative, his Mitra Pak Majid of Rencong Souvenir Crafts was able to provide capital support in the form of a bulk casting business.

Abstract

Charity activities in Limpok Village, Aceh Besar District, Darussalam District, Aceh State. This activity was carried out because there is a small river in the village and the water is not yet available as a source of water for the rice fields. The purpose of this activity is to obtain and distribute rice water to increase farmers' yields. As for the stage of activities, we hold round-table discussions with local residents about the water demand of paddy fields, investigate the locations of PVC pipes, and work with local residents to lay PVC pipes. This activity demonstrates the great enthusiasm of residents to participate in a series of community service activities. As a result of this activity, we succeeded in pumping up water from a small river to the rice fields, which had previously depended on rainwater. This charity should therefore serve as an example for other villages with similar problems and demonstrate the importance of cooperation between communities and government agencies in building and improving the quality of life in the region.
