Abstract

This Community Service Program was conducted to introduce and implement hydroponic technology that utilizes waste from Nile tilapia farming as a source of organic fertilizer. This activity was located in Dolok Sagala Village, Dolok Masihul District, Serdang Bedagai Regency. The method used in this PKM included training and direct mentoring of the community in creating and managing a hydroponic system for cultivating Brassica Rapa plants. This activity showed that the hydroponic system using fish waste as organic fertilizer produced high-quality Brassica Rapa plants. Additionally, this program provided the community with new knowledge about the benefits and potential of hydroponic technology as a modern agricultural solution in limited land areas. The success of this program is expected to be adopted more widely by the community to enhance local food security and economic welfare.

Abstract

This study aims to analyze the operational effectiveness of the Ripple Mill machine using a TPM maintenance strategy approach by measuring OEE. The method used is descriptive quantitative, with primary data from observations and interviews, and secondary data from factory operational documentation. The evaluation was based on three leading OEE indicators: availability, performance, and quality. It was complemented by an analysis of the six significant losses to identify sources of lost production time. The results show that the average OEE value from January to March 2025 reached 96.53%, exceeding the international standard of ≥85%. The most significant losses came from equipment breakdowns (69.75%), followed by minor breakdowns and idling (18.48%). Preventive maintenance programs, operator training, and spare parts availability are recommended. These results demonstrate the effectiveness of the TPM approach in continuously improving machine performance.
