Abstract

Where rainwater is stored in the form of barrels, tubs, or ponds. Oil is as important as water for human life. Because the majority of Indonesians like fried food, cooking oil is still needed for household needs. Used cooking oil, oil produced from frying, is often used to save money, but its carcinogenic properties can cause cancer in the future. The purpose of this activity is to change the paradigm and change the paradigm of PTPN III Sei Mangke mothers. The results of this activity were 25 people, namely the age range of 28-37 years with a percentage of 36%, and the highest education level was high school with a percentage of 48% and there was a paradigm shift where previously they did not know until they understood based on the results of the questionnaire survey of the activity

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

Partnerships between universities and partner institutions are strategic for study program accreditation and for implementing the Tri Dharma of Higher Education. In 2025, Al-Azhar University established an international collaboration with Universiti Malaysia Perlis (UniMAP) and the Village Forest Management Institution (LPHD) of Pasar Rawa, Langkat Regency, in the field of community service. The activities included a networking session, strategic discussions on converting palm oil plantations back into mangrove forests, and a joint mangrove planting action. This initiative aims to restore coastal ecosystems as habitats for marine life, such as fish, crabs, and shrimp. Through this synergy, it is expected that the motivation of the Pasar Rawa Village community, particularly the LPHD, will increase in managing and preserving the mangrove area sustainably for the welfare of the coastal ecosystem.

Abstract

This study aims to design and manufacture a displacer piston for a Gamma-type Stirling engine using steam pipe material due to its heat-resistant properties. The manufacturing process involved cutting, turning with a conventional lathe, and TIG welding. The final product dimensions were 65.75 mm in diameter, 60.20 mm in height, and 321.20 mm. Measurement results showed that the dimensional tolerances were within the design limits, and no leakage was found in the joints after visual inspection and basic functional testing. The study demonstrates that a simple process can produce a piston suitable for laboratory-scale applications.

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.
