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.

This article reviews the history and transformation of madrasah management in Indonesia. Emerging in the early twentieth century, madrasahs developed as educational institutions that combined the traditional values of Islamic boarding schools (pesantren) with the organizational structure of modern schools. This study employs a literature review method to examine the evolution of madrasah governance from the colonial era to the reform era. The findings reveal three major stages in the development of madrasah management. The first stage was the early period, during which madrasahs were independently managed by religious leaders and Islamic organizations with limited government involvement. The second stage was the post-independence integration period, characterized by increasing government intervention in curriculum development, institutional regulation, and legal recognition. The third stage was the modernization era, marked by the issuance of the Joint Decree of the Three Ministers in 1975 and the enactment of the National Education System Law of 2003, which strengthened the position of madrasahs within the national education system and placed them on an equal footing with public schools. These developments encouraged madrasahs to adopt Madrasah-Based Management (MBM) as a strategy to improve educational quality, effectiveness, and competitiveness. Overall, the transformation of madrasah management reflects an adaptive process that enables madrasahs to respond to educational reforms and societal changes while maintaining their distinctive Islamic identity and educational mission.

Down syndrome, or Trisomy 21, is the most common chromosomal disorder in humans and is primarily caused by nondisjunction events during meiosis. Although advanced maternal age has long been recognized as the major risk factor, recent scientific evidence indicates that genetic mutations, gene polymorphisms, and meiotic recombination abnormalities also play important roles in the occurrence of Trisomy 21. This literature review aims to analyze the role of genetic mutations in the pathogenesis of Trisomy 21, with emphasis on the mechanisms of nondisjunction, oocyte aging, meiotic recombination errors, and folate metabolism disorders. The method used was a narrative literature review based on seven major scientific sources discussing the genetic and molecular factors underlying Trisomy 21. The findings indicate that genetic mutations and variations affecting meiotic regulation, recombination positioning, chromosome cohesion, and DNA methylation significantly increase the risk of chromosome 21 nondisjunction. In addition, age-related decline in oocyte quality and polymorphisms in folate metabolism genes further exacerbate chromosomal instability. Understanding these mechanisms is essential for the development of genetic counseling, early detection, and more effective prevention and management strategies in the future.
