Abstract

Dalam kondisi pandemi Covid-19, dunia pendidikan tetap harus dapat memberikan pelayanan dengan kualitas yang terbaik kepada setiap peserta didiknya, maka diperlukan sebuah pengelolaan sistem yang cepat dan tepat, pihak pengelola harus segera dapat menghasilkan kebijakan-kebijakan terkait pelayanan yang diharapkan. Dalam usaha memutus mata rantai penyebaran Covid-19 maka pemerintah mengeluarkan beberapa kebijakan yang dapat dilakukan selama pandemi virus corona ini berlangsung. Salah satu kebijakan yang dilakukan yaitu mengubah kegiatan belajar mengajar menjadi sistem daring atau online atau sering disebut juga pembelajaran jarak jauh. Penelitian ini bertujuan untuk mengetahui 1) Efektifitas penggunaan aplikasi Zoom Cloud Meetings untuk pembelajaran jarak jauh, 2) Seberapa membantu aplikasi Zoom Cloud Meetings ini untuk peserta didik dan 3) Kelebihan dan kekurangan Aplikasi Zoom Cloud Meetings. Dari hasil penelitian ini, dapat disimpulkan bahwa aplikasi Zoom Cloud Meetings ini efektif dan sangat membatu peserta didik dalam memahami apa materi yang disampaikan. Namun terlepas dari itu, aplikasi Zoom Cloud Meetings ini masih mempunyai kekurangan saat digunakan oleh peserta didik.

Abstract

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.
