Abstract

In the village of Tanjung Meriah, Sitellu Tali Urang Jehe subdistrict, there are areca nut farmers who have the potential to increase the family's economy. The process of stripping areca nut from its fiber or skin is done traditionally using a makeshift machete. In the previous activity, a areca peeling machine was made using a machine, but currently it is constrained by periodic maintenance problems that need guidance. On this occasion, the areca nut farmers hope that the peeling of the areca nut will continue to run smoothly, of course, with the help of a machine, the stripping process will take a short time. The method of implementation is carried out by directly accompanying partners to practice how to maintain the areca peeler machine, starting with theory, machine demonstration and practice by each person in turn. The purpose of this activity is to provide knowledge on how to maintain the areca peeling machine after the community partnership program that was previously implemented, so that the community can maintain the continuity of the machine so that it can be used for a long time. The results of this program implementation have had a good impact on increasing partners' knowledge regarding the steps that must be taken in periodic engine maintenance. Another result that can be recommended to the Tanjung Meriah village community group is that they can make, develop their own without being accompanied by the PKM team because with sufficient knowledge from the results of the assistance that has been done before.

Abstract

Food security remains a major challenge for Islamic boarding schools with limited land and resources. This community service program aimed to optimize the use of vacant land at the Markaz Penghafal Al-Qur'an of Yayasan Layar Dakwah to improve food security. The implemented methods included raised-bed preparation, selection of superior seeds, and efficient crop maintenance. The results showed that proper land utilization increased food productivity while reducing dependence on external food supplies. Tomatoes achieved the highest productivity at 2.25 kg/m², followed by chili peppers at 1.75 kg/m² and shallots at 1.25 kg/m². To increase the added value of the harvest, female students received training on processing tomatoes into tomato sauce with a longer shelf life, as well as product packaging and marketing techniques. The program enhanced students' skills in post-harvest processing, enabled them to produce value-added products, and created entrepreneurial opportunities that can generate additional income while supporting the food security of the Islamic boarding school.

Abstract

This study investigates the effect of using Liquefied Petroleum Gas (LPG) as an alternative fuel to Pertalite on the performance, energy efficiency, and operating cost of a 6.5 HP gasoline engine-driven water pump. Experiments were conducted at three engine operating conditions: minimum, average, and maximum engine speeds. The evaluated parameters included engine speed, water discharge, hydraulic power, shaft power, brake specific fuel consumption (BSFC), thermal efficiency, overall system efficiency, and fuel operating costs. The results indicate that the pump's hydraulic performance, as measured by water discharge and hydraulic power, is not significantly affected by the type of fuel used. However, engines that use Pertalite tend to have slightly better thermal and system efficiencies than LPG engines. From an economic perspective, LPG offers a substantial advantage, with lower operating and energy costs per unit of power. Therefore, despite Pertalite's slightly superior technical efficiency, LPG is a more economical alternative fuel for long-duration water pump applications.

Abstract

The design and manufacturing of a heater for a Gamma-type Stirling engine on a small scale require careful consideration of key factors to ensure thermal efficiency and optimal performance. This study utilized AutoCAD software to design the heater precisely according to operational requirements. The heater functions as a critical component that transfers heat from the source to the working fluid positioned at the front of the Stirling engine. The manufacturing process employed carbon steel, chosen for its ability to withstand high temperatures and ensure even heat distribution. Test results demonstrated that the manufactured heater could achieve an average temperature of 484.50 °C, reflecting its stability and optimal heat distribution during operation. This stability is a crucial indicator of the heater's thermal efficiency and reliability in supporting the Stirling engine's performance. The study confirms that the applied design process, material selection, and manufacturing techniques successfully produced a heater that meets the design specifications. Thus, this research significantly contributes to developing heater technology for small-scale Stirling engine applications.

Abstract

The palm oil industry in Indonesia generates a large amount of solid waste in the form of Empty Fruit Bunches (EFB). This waste is often underutilized and poses environmental challenges. The high lignocellulosic content of EFB offers significant potential for its development as a renewable biomass fuel. This study aims to evaluate the proximate composition and calorific value of EFB to assess its feasibility as a raw material for bio pellets. The experimental procedures included drying, shredding, grinding, and palletization, followed by laboratory testing based on SNI 8021:2014, SNI 7709:2019, and EN ISO 17225 standards. The results showed a moisture content of 7.85% and an ash content of 7.97%, both within acceptable limits, although the ash level was relatively high. Furthermore, EFB contained 24.20% carbohydrates and 37.99% crude fiber, which contributes to the structural stability of the bio pellets. The calorific value obtained was 1200 kcal/kg, which is considerably lower than values reported in previous studies (≥3500 kcal/kg). These findings highlight the potential of EFB as a renewable energy source while underscoring the need for process optimization to meet quality standards, with possible applications in small-scale and household energy generation.

Abstract

This research focuses on developing a special LPG burner for the mCHPSE-012021 Stirling engine. The burner design was developed using CAD software and fabricated using machine tools and a welding process. Tests are carried out to verify how much the burner performance meets the desired specifications. The test results show that although the burner can reach the required high temperature, the thermal efficiency is still low, at 19.72%. This figure is far below the efficiency standard for household gas stoves, according to SNI 8660:2018. These findings highlight the urgency of improving burner design and efficiency to meet established standards, improving the mCHPSE-012021 Stirling engine's overall performance, and significantly increasing energy efficiency. These improvements are necessary to ensure optimal performance and efficiency in energy use in mCHPSE systems, underscoring the importance of developing more efficient and standards-compliant burner technology to support the use of Stirling engines in microenergy applications.
