Abstract

Kondisi ruangan yang nyaman dapat mempengaruhi performa kognitif serta kreativitas penghuninya. Ini dapat menjadi salah satu perhatian dalam merencanakan ruang-ruang diskusi akademik di kampus yang mendukung pembelajaran dan kolaborasi mahasiswa serta dosen. Mengingat iklim tropis Indonesia, diperlukan sistem pendingin yang efektif untuk menjaga kenyamanan penghuni ruangan. Penelitian ini menganalisis beban pendinginan di suatu ruang yang peruntukan utamanya adalah untuk diskusi. Dalam penelitian ini, dilakukan analisis pada beban pendinginan serta perbandingan dengan kapasitas pendinginan terpasang dari salah satu ruang diskusi di Institut Teknologi Sumatera (ITERA). Tujuannya adalah untuk mengevaluasi serta merekomendasikan kapasitas pendinginan yang ideal. Metodologi yang digunakan mencakup pengukuran karakteristik ruangan, sumber panas internal dan eksternal, serta faktor transmisi panas. Hasil analisis menunjukkan bahwa kapasitas sistem pendingin ruangan yang terpasang saat ini lebih kecil daripada beban pendinginan yang diperlukan dalam dua skenario yang dianalisis, yaitu dengan semua lampu dinyalakan dan dimatikan. Faktor-faktor seperti jumlah penghuni, penggunaan peralatan, pencahayaan, serta transfer panas melalui dinding dan jendela berkontribusi terhadap tingginya beban pendinginan. Hasil studi ini menyarankan perlunya peningkatan kapasitas pendinginan guna memastikan kenyamanan termal di ruangan serta efisiensi energi.

Abstract

The inappropriate use of heavy equipment in the field's conditions and situations can result in various losses, including low production, failure to meet scheduled targets, or unnecessary repair costs. Troubleshooting in the lubrication system often occurs due to reduced flow in the distributor and clogged distributor lines. The aim of this research study is to understand the troubleshooting process performed on the automatic lubrication system of the Bucket Wheel Excavator-205 substructure. Although automatic lubrication systems are designed to enhance efficiency and operational reliability, technical issues can sometimes occur, disrupting system performance. Data collection methods include field observations, data analysis, and experiments. The research findings indicate that common problems include lubricant leaks, decreased lubrication pressure, and sensor malfunctions. Based on the analysis of causes, appropriate solutions have been implemented, including mechanical repairs, replacement of damaged components, and enhanced preventive maintenance. It is hoped that the results of this research will contribute to improving the efficiency, reliability, and lifespan of the automatic lubrication system on Bucket Wheel Excavator-205, as well as providing guidance for better maintenance in the future.
