This study was conducted based on the crucial role of diesel generator engines as the primary source of electrical power on board ships, making their operational reliability essential. One of the factors influencing generator engine performance is lubricating oil temperature. Excessive lubricating oil temperature may reduce lubrication effectiveness, increase friction between moving components, and lower engine efficiency. Therefore, this research aimed to identify the causes of high lubricating oil temperature in diesel generator engines and determine appropriate corrective actions. The study employed a descriptive quantitative approach. Data were collected through direct observation, interviews, and documentation during sea practice aboard MV. CL FLANDERS from 4 July 2024 to 5 July 2025. The data were analyzed using simple linear regression to examine the relationship between generator load and lubricating oil temperature. The findings revealed that generator load had a significant effect on the increase in lubricating oil temperature. Under normal operating conditions, the lubricating oil temperature ranged from 60°C to 72°C, while under abnormal conditions it increased to between 68°C and 81°C. The abnormal rise in temperature was mainly caused by cooling system problems, particularly a dirty LO cooler, scale deposits on the sea water pump impeller, and blockage in the cooling capillary pipes. The regression equation under normal conditions was Y = 45 + 0.30X, whereas under abnormal conditions it was Y = 53.5 + 0.30X. Elevated lubricating oil temperature resulted in lower oil viscosity, higher fuel consumption, and reduced diesel generator engine performance. Therefore, regular maintenance of the LO cooler, sea water pump, and continuous temperature monitoring are necessary to maintain optimum engine performance.

Cigarette smoke is a major source of free radicals that can cause various health problems, including disturbances in the male reproductive system. Nicotine and other harmful compounds in cigarettes increase oxidative stress and interfere with spermatogenesis. Gotu Kola (Centella asiatica) is a medicinal plant known for its antioxidant properties that may help neutralize free radicals. This study aimed to determine the effect of Gotu Kola leaf extract on the histopathological features of the testes in male Wistar rats exposed to cigarette smoke. An experimental study using a Post-Test Only Control Group Design was conducted on 24 rats divided into six groups: a normal group, a negative control group exposed to cigarette smoke, a positive control group treated with vitamin E, and three treatment groups receiving Gotu Kola extract at doses of 120, 180, and 240 mg/kg body weight for 28 days. The observed parameters were Leydig cell count and seminiferous tubule diameter. One-way ANOVA analysis showed that Gotu Kola extract significantly increased Leydig cell numbers and seminiferous tubule diameter in all treatment groups compared to the negative control group (p < 0.05). Post hoc analysis demonstrated significant differences in tubule diameter, with the highest improvement observed at the 240 mg/kg body weight dose. These findings indicate that Gotu Kola extract has potential protective effects against testicular damage caused by cigarette smoke exposure.

Climate change is a global issue that not only impacts the environment but also threatens a country's food security. Indonesia, as a country that relies heavily on the agriculture, fisheries, and livestock sectors, faces high vulnerability to climate change. This study aims to analyze the impact of climate change on the agriculture, livestock, and fisheries sectors. This study used a qualitative method with a literature study approach through data analysis derived from scientific journals, books, and institutional reports. The results of the study indicate that climate change has a significant impact on these three sectors through changes in weather, rainfall patterns, and extreme weather. The El Niño phenomenon can reduce agricultural production, reduce livestock productivity, and disrupt fishermen's catches. These conditions can disrupt national food availability and stability and can increase social and economic vulnerability of the community.

This study traces the history of the development of Islamic educational organizations in Indonesia from the pre-colonial period to the Reformation era using a descriptive qualitative approach through a literature review. The findings indicate that Islamic education developed gradually, beginning with informal institutions centered around mosques and pesantren, and later responding to colonial pressures with the emergence of organizations such as Muhammadiyah and Nahdlatul Ulama. This development continued through the formal recognition of madrasahs during the independence era, modernization under the New Order regime, and more dynamic institutional transformations during the Reform era. Amid various challenges such as educational dualism, resource constraints, and the threat of extremism, Islamic educational organizations continue to innovate by integrating religious and general knowledge without abandoning their Islamic identity. This study affirms that Islamic educational organizations are the primary foundation for building a character-based national education system.

Madrasas as formal Islamic educational institutions in Indonesia have undergone a long evolution from traditional systems to modern institutions that are integrated into the national education system. This study aims to examine the role of Islamic education management in the development of madrasah history using a literature research method with an analytical descriptive approach. The results of the study show that the development of madrassas takes place through several historical phases that are mutually sustainable. In the early 20th century, madrassas emerged in response to the limitations of the traditional pesantren system. In the pre-independence period, the discriminatory policies of the Dutch colonial encouraged the birth of modern madrassas that combined religious and general sciences. Post-independence, the establishment of the Ministry of Religion in 1946 strengthened the position of madrassas in the national education system. During the Old Order period, the number of madrassas increased rapidly even though the management was still community-based. Entering the New Order, the Decree of 3 Ministers of 1975 and Law Number 2 of 1989 encouraged the formal integration of madrasas, although they tended to be centralistic. The Reform Era through Law Number 20 of 2003 provided equal recognition to public schools and encouraged decentralization based on School-Based Management. Although the quantitative and legal development of madrasas is significant, the challenges of quality, funding, and relevance in the era of globalization remain a concern so that madrasas are able to produce graduates who excel intellectually and are solid in Islamic values.
