Evaluasi Keselamatan Kerja Listrik Laboratorium Permesinan Kapal Universitas Maritim AMNI Semarang Dengan Metode Analitycal Network Process (ANP)

In the operation of electrical components in the ship engineering laboratory of the Maritime University of AMNI Semarang, various kinds of protection are needed. Errors in installing and operating electrical equipment can reduce protection. This protection aims to improve the safety of electrical work in ship engineering laboratories. And in the application of electrical work safety, it is necessary to evaluate based on the 2000 Electrical Installation General Requirements standard (PUILL 2000). The purpose of this study was to evaluate the use of the laboratory of the Maritime University of AMNI Semarang in the aspect of work safety. Based on the results of the evaluation, the criteria for electrical work safety are determined, namely: protection for safety, protection from overvoltages and currents, protection from thermal effects, and protection from fault currents. After the evaluation was carried out, alternatives were found to improve electrical safety: standard operating procedure (SOP), an inspection of cable installations, checking MCB panels and switches. The criteria and alternatives obtained then processed using the software super decision ver.2.10.0 with the Analytical Network Process (ANP) method so that the priority results of electrical safety improvements in the ship engineering laboratory of AMNI Maritime University Semarang are: repair of SOP 63.7%, cable installation 25.8%, MCB panel, and 10.5% switch.

Competence Based Training (CBT) Teknik Pengelasan Untuk Meningkatkan Keterampilan Taruna Teknika Kapal Niaga

The high demand for competence in the world of the shipping industry today demands an increase in the skills of the Commercial Ship Engineering Study Program cadets, especially in the field of welding techniques. This indicates that Taruna's welding technique skills are still low. This Community Service Activity aims to improve welding technique skills and welding understanding for cadets. The Community Service Activity method uses the Competence-Based Training (CBT) Model, which combines theory, demonstration, and practicum. Evaluation is done by doing a pre-test, and post-test. CBT participants are 11th grade cadets of SMK Pelayaran Muhammadiyah 1 Kalasan Yogyakarta, with the expertise of Commercial Ship Engineering, with a total of 25 cadets. The results of the evaluation of Community Service were an increase of 60% in theory mastery, an increase of 64% in understanding demonstrations, and an increase of 84% in the skills of cadets in welding practice

Application of New Energy Natural Gas in Ship Engineering

<p>Traditional ships are mainly fueled by diesel or gasoline, which are produced from the oil and are non-renewable. People are now rapidly consuming oil and burning oil generates poisonous gases day and night. Because of the soaring oil prices and the deteriorating ecology, many ship-owners are seeking an alternative energy to replace oil. Among all possible candidates, the calling of natural gas is getting higher and higher. This paper discusses the application of natural gas in ship engineering, and explains in detail the advantages and disadvantages. Natural gas may not be a new energy but has rarely been used in ship engineering so far. We conclude that its application in ship engineering helps to alleviate the fuel shortage in the future. </p>
