The issue of climate change due to the greenhouse effect encourages various parties to try reducing emissions in energy fulfilment. In maritime sector, IMO has adopted mandatory measures to reduce emissions of greenhouse gases (GHG) from international shipping, under IMO's pollution prevention treaty (MARPOL). Besides Carbon Oxides (COX), statistics show that other exhaust emissions from ships, such as Sulfur Oxides(SOX), Nitrogen Oxides(NOX) and Particulate Matters(PM) have also increased significantly in the past years due to the rapid increase of the maritime transportation. It is necessary for the shipping industries to find out the available clear energy to reduce the emission of GHG. This paper will discuss application of solar and wind energy on ship power systems, current status and future prospect.

Pupuk Indonesia Logistik serves various activities that support shipping activities. In running its commercial business in sea transportation services, PT Pupuk Indonesia Logistik has nine ships, and one of them is KM Abusamah. PT Pupuk Indonesia Logistik encountered obstacles during unloading. These happened when KM Abusamah on Voyage 5 transported bulk urea fertilizer belonging to PT Pupuk Sriwidjaja Palembang, sailing from Tanjung Buyut Port in Palembang to Banyuwangi Port. However, when the unloading took place on April 21, 2021, the KRI Nanggala 402 accident occurred, which lost contact in the northern waters of Bali, thus hampering the unloading process. The purpose of the study was to identify the causes of return cargo at KM Abusamah, to know how to handle the return cargo of 124,893 MT of bulk urea fertilizer, and to know the responsibilities of the shipper, carrier, and consignee. This research aims to identify the cause of return cargo on KM Abusamah. The data analysis technique used is the descriptive analysis of fishbone diagrams with the application of 4M, namely Man, Method, Material, and Machine. The data was obtained through documentation, literature study, and interviews. The causes of cargo returns were maintenance activities and the KRI Nanggala 402 accident. How to handle cargo returns by bringing the cargo back to the port of origin and transporting it for the next voyage.

Baja telah lama digunakan secara luas didalam industri kapal sebagai komponen plat utama didalam badan maupun lambung kapal. Disatu sisi material baja didalam kapal sangat rentan terhadap serangan korosi yang dapat menurunkan kualitas material kapal. Derajat keasaman atau pH adalah jumlah ion H+ yang terdapat di dalam sistem perairan atau biasa dikenal tingkat keasaman. Air laut umumnya mempunyai pH yang rendah (cenderung asam) sehingga menyebabkan korosi yang cepat di bagian bagian terbuka pada lambung kapal akibat cat lambung kapal yang tergores. penelitian ini dilakukan untuk mengetahui seberapa besar faktor salinitas dan derajat keasaman (pH) mempengaruhi laju korosi terhadap baja pada material kapal dan mengidentifikasi air laut yang laju korosinya tinggi di lihat dari pengaruh faktor derajat keasaman dan salinitas air laut. Hasil penelitian ini yaitu dapat mengkonfirmasi dan membuktikan pengaruh kadar salinitas dan pH air laut terhadap laju korosi. Semakin tinggi salinitas maupun pH, semakin tinggi juga laju korosinya.

A turbocharger is an auxiliary engine that functions to supply air into the cylinder and in general every turbocharger has two sides, namely, the compressor side and the turbine side, the rotation of the turbocharger is generated from the remaining exhaust gases from combustion in the cylinder which goes to the turbine side of the turbocharger and produces rotation. on that side and also rotates at the same speed on the compressor side of the turbocharger. The amount of air that will enter the cylinder depends on the rotation of the turbocharger itself, if the rotation of the turbocharger is too fast it will produce too much air in the cylinder which results in knocking or knocking on the main drive engine, whereas if the turbocharger rotates too slowly it will result in too little quantity of air resulting in a misfire or failure of combustion in the cylinder. To determine the rotational speed of the turbocharger, we need a tool that can regulate the quantity of the remaining exhaust gases from combustion in the cylinder, namely the waste gate valve. When the writer carried out the sea practice, the writer experienced various interesting things about the waste gate valve, such as the opening that did not match the degree of the waste gate valve to the difference in the indicator readings on the waste gate valve. In this case the author will analyze the cause of the imperfect supply of air entering the cylinder caused by the non-optimal performance of the waste gate valve.

The reciprocating bilge pump is an important auxiliary device in the bilge system in the engine room which functions to pump bilge from the bilge tank or engine room gutter to the OWS (Oily Water Seperator) and forward it to the ship's overboard. Reciprocating bilge pump is a type of reciprocating pump (piston pump) which is widely used for pumping viscous liquids or water mixed with oil. This pump generally consists of a pump housing or pump cylinder in which there is a plunger or piston which works by moving from TMB (Bottom Dead Point) to TMA (Top Dead Point) to suck liquid into and push it back out of the cylinder. This study aims to find out the causes of the problems and the efforts that can be made on the reciprocating bilge pump so that it can restore the performance of the reciprocating bilge pump. The research method that the authors used in compiling this research is a qualitative descriptive research. While data analysis is to identify the data set that has been obtained, so that the data can be analyzed and the purpose is analyzed in order to get a clearer picture in the preparation of this research both from the problems and the final results. It is hoped that this research research can produce ideas, solutions and appropriate problem solving, both in observing and handling the problems raised in this research. Based on research on the reciprocating bilge pump at MV. Amanah Halmahera AMC this pump is not working. This is caused by the release of the piston head from the piston rod so that there is no pressure on the pump and the check valve does not work properly so that it is difficult for the fluid to be sucked into the pump chamber. To prevent this problem, it can be done by reinstalling the check valve and cleaning the check valve.

Background: Maritime professionals face intense physical and mental demands, yet vocational education often overlooks structured fitness and balanced nutrition, focusing primarily on technical skills. This study explored the impact of integrating these elements on cadet endurance, cognitive function, and career sustainability, addressing a gap in existing research that rarely assesses fitness and nutrition systematically. Through qualitative insights from lecturers, graduates, and cadets, this research aimed to identify implementation challenges and evaluate perspectives on fitness scheduling, dietary adequacy, and career preparedness, ultimately offering practical recommendations for enhancing maritime training programs. Methods: This study employed a qualitative descriptive approach, utilizing semi-structured interviews, focus group discussions, and participant observation to explore the integration of physical training and nutrition in maritime education. Participants included 5 lecturers, 10 graduates, and 25 cadets, providing diverse perspectives. Data analysis followed a thematic qualitative approach, including cross-group comparisons and narrative synthesis, to identify recurring patterns and develop evidence-based recommendations for enhancing maritime training programs. The study assessed cadet performance, endurance, and career preparedness through indicators such as engagement in physical activities and perceived nutritional adequacy. The findings aimed to contribute to a more resilient and health-conscious maritime workforce. Results: Findings indicate that structured physical training improves cadet endurance and teamwork, while nutritional planning remains inconsistent, affecting energy levels and long-term health. Cadets expressed challenges in balancing fitness with coursework, suggesting the need for optimized scheduling and nutritional education. Conclusions: To enhance maritime workforce sustainability, institutions should integrate structured physical training, standardized meal plans, and nutritional awareness programs. Future research should assess long-term effects of fitness and dietary habits on seafarer health and career performance.
