Abstract

This study aims to make a preventive maintenance plan for tofu presses and cutters with a pneumatic system with the methods carried out namely inspection, small repair, medium repair and overhaul (ISMO). The preventive maintenance time on presses and tofu cutters with this pneumatic system is carried out with this type of maintenance on a monthly and annual basis. The research stages of implementing preventive maintenance on tofu presses and cutters with a pneumatic system includes literature studies, making maintenance schedules and expert validation. Components carried out preventive maintenance on the mechanical system which includes the frame, drive system, compressor and blades. data collection using observation and documentation. data were analyzed descriptively quantitative. The results showed that the preventive maintenance of tofu presses and cutters with a pneumatic system was intended to maintain the condition of the tools as well as to extend their service life and streamline the production process.

Abstract

This study aims at hazard identification and risk assessment in an effort to prevent work accident at the Subang State Polytechnic's Combustion Engine Laboratory. This research is a qualitative-descriptive study with an observation stage using the hazard identification and risk assessment (HIRA) methods. Data were analyzed using Australian Standard/New Zealand Standard (AS/NZS) measurements. Conclusions from the results are: (1) occupational health and safety have not been implemented optimally in the Combustion Engine Laboratory; (2) 9 hazards were found in the laboratory consisted of 1 hazard in the H (high) category, 2 hazards in the M (moderate) category, and 6 hazards in the L (low) category, but none were in the extremely danger category; (3) recommended actions to be taken to reduce the danger in the laboratory are defining laboratory standard operating procedure, rearrangement of laboratory layout and equipment, and briefing students with clear instructions before and after practical work.Penelitian ini bertujuan untuk mengidentifikasi bahaya dan menilai risiko, harapannya dapat mencegah terjadinya kecelakaan kerja di Laboratorium Motor Bakar Politeknik Negeri Subang. Penelitian ini merupakan penelitian deskriptif kualitatif dengan tahap observasi menggunakan metode hazard identification and risk assessment (HIRA). Data selanjutnya dianalisis menggunakan pengukuran yang digunakan dalam Australian Standard/New Zealand Standard (AS/NZS). Hasil penelitian dapat disimpulkan bahwa: (1) penerapan kesehatan dan keselamatan kerja (K3) di Laboratorium Motor Bakar belum optimal; (2) ditemukan 9 bahaya (hazard) di Laboratorium Motor Bakar yang terdiri dari 1 bahaya dalam kategori H (high), 2 bahaya dalam kategori M (moderate), dan 6 bahaya dalam kategori L (low) namun tidak ada yang masuk dalam kategori bahaya ekstrem; (3) rekomendasi tindakan yang dapat dilakukan untuk mengurangi bahaya di Laboratorium Motor Bakar yaitu pembuatan SOP laboratorium, penataan kembali tata ruang dan peralatan, serta pemberian instruksi sebelum dan sesudah praktikum kepada mahasiswa.

Abstract

Community service activities are in the form of making tools and assistance in building clean and comfortable villages and reducing the risk of flooding due to accumulation of garbage in the coastal watershed (DAP) Mayangan Village, Legon Kulon District, Subang Regency, West Java Province. 12 August – 30 September 2021. The results of this community service are plastic waste processing machines and the formation of youth who care about waste in Mayangan Village. The results of this community service conclude that (1) the coastal watershed (DAP) environment is clean of plastic waste; (2) training on waste management and the dangers of waste is carried out to increase public awareness of the dangers of plastic waste; (3) plastic waste processing equipment is expected to reduce waste that causes flooding.

Abstract

The research in this final project aims to determine the preventive maintenance schedule for the plastic waste smelter and to determine the application of preventive maintenance to the plastic waste smelter. The maintenance process for this tool uses preventive maintenance with inspection, small repair, medium repair and overhaul (ISMO) methods. The implementation method of waste smelter into plastic involves data collection through direct observations of the smelter area, component identification, maintenance schedule planning, expert validation, and routine preventive maintenance execution. The research findings indicate that the systematic and scheduled application of maintenance effectively preserves the optimal performance of the smelter machine. These measures not only enhance operational efficiency but also reduce the risk of damages and potential downtime that could disrupt the production process, contributing to the sustainability and quality of plastic waste processing.
