Abstract

Community service is the main principle upheld by higher education institutions in fighting for the empowerment and advancement of society. This paper aims to illustrate the important role of the Department of Arabic Language and Literature at UIN Alauddin Makassar in implementing community service programs, with a case study at Pondok Pesantren al-Ikhlash Addary DDI Takkalasi, Barru Regency. Through a qualitative approach and direct observation, this article discusses the various service activities carried out by the department in improving the quality of life and empowering the local community. The results show that the role of the Department of Arabic Language and Literature is very significant in making a positive contribution to the pesantren and the surrounding community, especially in terms of scientific development and cultural maintenance.

Abstract

This study aims to analyze the thermal performance of the starboard main engine on a tugboat, specifically a Mitsubishi type S6R2-T2MTK3L, by focusing on the phenomenon of exhaust gas temperature increase. Measurements were conducted over six days under two operational conditions: towing an empty barge and towing a fully loaded barge. The results indicate that the exhaust gas temperature was significantly high in both conditions, with a temperature difference of 40 °C at low engine speed and up to 100 °C at high speed. These findings suggest incomplete combustion, indicating the need for further improvement in the engine's combustion process. Meanwhile, fuel temperature remained relatively stable in both conditions, with a maximum difference of only 3 °C at medium and high engine speeds, suggesting that the fuel delivery system is operating safely. The analysis of specific fuel consumption (SFC) revealed inconsistent trends in relation to engine speed. The highest SFC was recorded at 600 rpm while towing a fully loaded barge, at 0.01855 l/kWh. The highest engine torque was 7523.885 Nm at medium speed, while the lowest torque was 7165.605 Nm at high speed. This study concludes that high exhaust gas temperatures serve as a primary indicator of combustion inefficiency in the starboard main engine, requiring further evaluation to maintain operational efficiency and safety of the tugboat.
