Abstract

Intensification of catfish farming at high stocking density is often constrained by drastic water-quality degradation, including increased turbidity, which can trigger stress and mass mortality in commodities. This study aims to design and build an Internet of Things-based automatic catfish pond water turbidity control system to maintain water parameter stability according to quality standards in real-time. The research method applied is Research and Development, which includes microcontroller-based hardware design, optical turbidity sensor integration, and web-based monitoring interface development. The system uses an on-off control algorithm with a hysteresis technique to intelligently regulate the circulation pump's activation at a danger threshold of 50 Nephelometric Turbidity Units and a safe limit of 25 Nephelometric Turbidity Units. The main findings indicate that the system has a very fast dynamic response, with a sensor delay of less than 2 seconds. In maximum disturbance load testing, the device successfully restored water clarity in an average time of 165 seconds without actuator oscillation. This study concludes that integrating automatic control technology and remote monitoring effectively improves water quality management efficiency and mitigates the risk of harvest failure for farmers.

Abstract

Conveyor system efficiency is essential for maintaining smooth material flow in beverage manufacturing. At PT XYZ, frequent empty-can jamming (infeed stuck) in the multi-to-single conveyor section caused significant filler machine downtime and reduced production efficiency. This study investigated the effect of optimizing the side guard angle from 3° to 2° on reducing infeed stuck and improving Overall Equipment Effectiveness (OEE). Operational data were collected over five working days through direct observation, production reports, and angle measurements using a digital angle finder. Conveyor performance was evaluated using the availability, performance, and quality components of OEE. The results showed that reducing the side guard angle to 2° improved material flow by decreasing the average infeed stuck duration from 128.0 to 73.1 minutes. Product defects were reduced from 65 to 9 cans, while the production rate increased from 36,300 to 47,760 cans/h. Consequently, the OEE increased from 55.36% to 83.92%, representing an improvement of 28.56%. These findings demonstrate that optimizing the side guard angle effectively minimizes conveyor downtime and speed losses while enhancing production efficiency. The proposed adjustment provides a practical basis for standardizing conveyor setup to improve manufacturing productivity
