Abstract

The loading and unloading process at the port determines the smooth running of the economy, and this cannot be separated from the role of the Loading and Unloading Workers (TKBM) at the port. In its development, TKBM in ports has become very important because it determines the smoothness of the loading and unloading process, so it requires loading and unloading workers with expertise and reliability in using tools during loading and unloading and applying K3 principles. Bitung Port is one of the important factors that drive economic growth and development in North Sulawesi. At Bitung Port, it was confirmed that more than 1000 TKBM were carrying out loading and unloading activities. This research aims to determine the effect of competency and training on TKBM performance at Bitung Port, North Sulawesi. The research method uses quantitative research with data collected through questionnaires. The research results show that TKBM competency and training simultaneously influence TKBM performance at Bitung Port.

Abstract

Induction Furnace is equipment that is widely used in the metal or steel industry, this equipment is usually used to process metallic or non-metallic minerals in the reduction or smelting process. Induction furnaces have a frequency value in an induction furnace that can reach 2000Hz, and the DC voltage can be adjusted to reach 800VDC. By using a filter you can reduce harmonics as small as possible until the waveform is closer to sinusoidal. Research to analyze the steps for installing a hybrid filter to reduce harmonic distortion. The analysis results from the hybrid filter simulation can reduce the total harmonic distortion value with the THD value according to IEEE 152-1992.

Abstract

Background: Waste management and pollution prevention in naval engineering operations are critical to minimizing environmental damage and ensuring regulatory compliance. The Sulawesi Sea’s fragile ecosystem and maritime sustainability goals necessitate an effective and structured waste management framework for naval institutions. Despite the existence of environmental regulations, challenges persist in compliance enforcement, cadet training, and operational waste disposal efficiency. Original Value: This research contributes to naval environmental sustainability by developing a structured waste management model tailored to naval engineering training institutions. Unlike previous studies that focus on commercial shipping waste, this study provides a specific analysis of waste generation in naval engineering settings and offers targeted improvements for pollution prevention. Objectives: The study addresses how an optimized waste management and pollution prevention model can improve environmental sustainability in naval engineering operations, while also identifying training gaps and regulatory compliance challenges. Methodology: The research employs qualitative analysis through expert interviews, field observations, and structured surveys to evaluate current waste management effectiveness, regulatory adherence, and cadet engagement. Results: Findings indicate that waste segregation and pollution prevention measures are effective (88-92/100), but regulatory enforcement and hands-on cadet training require improvement (85/100). The proposed model is feasible (87/100) and cost-effective (89/100), ensuring long-term operational sustainability. Conclusions: Implementing structured waste policies, enhanced training modules, and technological advancements will optimize waste management in naval institutions, reducing environmental impact while improving regulatory compliance and operational efficiency.

Abstract

As industries seek to improve product quality and reduce costs, automation tools like 3-phase induction motors have become indispensable due to their simplicity, cost-effectiveness, efficiency, and ease of maintenance. This study investigates the automation of monitoring for 3-phase induction motors through the integration of various components, including the A3114 Hall Effect sensor, PZEM-PP4T sensor, 20x4 LCD, ESP32 module, relay, Mitsubishi D700 inverter, and MCP 4725 sensor. Testing results show high accuracy in measuring critical motor parameters such as speed, voltage, and current. The Hall Effect sensor demonstrated an average accuracy of 4.12% compared to a tachometer, while the PZEM sensor exhibited a 0.90% accuracy for voltage and a 0.98% accuracy for current when compared to a multimeter, affirming the reliability of the system. Overall, the system provides consistent and precise measurements, transforming manual monitoring into an efficient automated process. This advancement significantly enhances the reliability and effectiveness of 3-phase motor monitoring in industrial applications
