Abstract

In today's digital era, the use of information technology (IT) in public services is a must. One of the implementations is the use of websites in public services. This website is designed to improve information accessibility services to the public (users), making it easier for people to access public services at the Marine and Fisheries Polytechnic of Bitung without having to come to the office. Other benefits that have been felt include more transparent services, the public can see the status of services in real time and help increase campus accountability. In this research, in developing the website, the author used the Waterfall method. The reason for using it is that the stages of work are sequential, interrelated, and easy to develop. After implementing the Waterfall method on the Polytechnic Integrated Online System (PIOnS) website, the results show that it can save time and costs when using public services, accurate, effective, fast, realtime, accountable, and more useful. The next result is that on the PIOnS website there are five types of services, namely Basic Safety Training (BST), Air Blast Freezer (ABF)/Cold Storage, Ship Docking, Ship Machinery Workshop and Training Ship Fleet.

Abstract

This study aims to evaluate the responsibilities and work intensity of fishing vessel crews in the operation of purse seine gear, as well as to identify potential occupational hazards at each operational stage. The research was conducted aboard KM. Bintang Mas Maritim operating in Fisheries Management Area (FMA) 713 from January to April 2024. A descriptive quantitative approach was applied using Hierarchical Task Analysis (HTA) to map crew tasks into primary and secondary activities, enabling the analysis of workload and potential risks. Data were collected through direct observation and semi-structured interviews with crew members meeting the inclusion criteria. The results identified eight main activities and 57 sub-activities in purse seine operations, with a total work intensity (IKT) of 559 Occupational Activities (OA), comprising 526 primary OAs and 33 secondary OAs. The hauling stage was found to be the most hazardous, with the highest work intensity of 141 OAs. These findings highlight the importance of leadership and safety management in effectively allocating crew responsibilities. This study provides a foundation for improving both crew safety and operational efficiency in purse seine fishing.

Abstract

Fishing boat technology utilizing an electric motor drive system has been developed as one of the innovations in marine vehicle design. Electric boats can move using the torque force generated from the electric motor to rotate the motor shaft, which is connected to the propeller. The aim of this research is to evaluate the torque force produced by an electric engine using the prony brake method. The research method employed was an experimental approach, focusing on variations in load, external diameter of the motor shaft pulley, and motor rotation. The results of experimental calculations show that the prony brake test can be used as an instrument in the approach method for calculating torque. The torque value is influenced by the pulley diameter and load variations. The largest torque value for variations in load and pulley diameter is at a pulley diameter of 3 inches and a load of 8 kg, namely 3.10 Nm. Changes in motor shaft rotation (rpm) affect the increase in torque. The largest torque value in the rotation variation is at 800 rpm and a load of 8kg for each diameter variation; 4.31 Nm (2 inches), 5.34 Nm (2.5 inches), 6.46 Nm (3 inches). The torque obtained is used as a reference in determining the capabilities of the electric engine and the capabilities of the fishing boat prototype while operating at sea.
