⎯The Mayangan Beach Fisheries Port (BFP) in Probolinggo City is a fishing port that was established using a combination of funds from the State Revenue and Expenditure Budget and Regional Revenue and Expenditure Budget of East Java province and Regional Revenue and Expenditure Budget of Probolinggo city. Equipped with basic and functional facilities to support various fishing activities, fishing vessels generally use a mechanical propulsion system driven by a diesel engine. The results of the government's decision to increase fuel prices by IDR 8,000/liter, were then supported by a survey which showed that fishermen needed as much as 110 liters of fuel for a journey of approximately one hour for one trip, with these conditions making fishermen, especially in the Mayangan district, Probolinggo very objection by increasing the price of fuel that will be used to go to sea, so that with the problems complained of by fishermen on the Mayangan coast, Probolinggo about rising fuel prices, this refers to researchers planning a hybrid propulsion system to reduce consumption of the use of fuel that will be used for purse seine fishing boats. The results showed that the main engine specifications for the Mitsubishi ship were 6D24-Mpt (A) with 228 Kw power, then the Yanmar Ytg 15 Tlv generator, while the electric motor specifications that would be used were Weg Tru Metric 132 Kw / 175 HP, as well as batteries for storing battery energy which had specifications J185-Agm Vrla Agm / Non-Spillable. The difference in fuel consumption in the conventional system and the hybrid system looks quite significant. Using a hybrid propulsion system can produce fuel savings of up to 30% when compared to using a conventional engine.

“…Research on the conveyor wing shape type effect on ocean waste collection behavior was investigated by Sugianto al [9], the result showed that the circle wing holes are faster in collecting garbage. Research on effect of portable conveyor placement in ship on ocean waste collection behavior was done by Sugianto el al [10], the results show that the conveyor on the bow model is the easiest to get the ocean waste closer to the conveyor. This model also produces the smallest ship resistance compared to other models.…”

In this paper an attempt has been made to assess how effective waste-collecting use catamaran ship with conveyor in the front. Numerical investigation based on Reynolds Averaged Navier Stokes (RANS) for predicting the flow pattern characteristics, velocity contour, and ship resistance. The focus of the present study is the impact of catamaran ship hull front shape on waste collection in calm water through the numerical methods. The three variations of the front of the hull used are symmetrical hull type, inner flat, and outer flat. It is done using speed variations of 1 to 4 knots. The results show inner flat hull catamaran has the smallest total resistance value than others. In addition, analysis of the flow pattern in front of catamaran shows that outer flat hull catamaran is the easiest to make waste closer to conveyor. From analysis of velocity contours shows that outer flat hull catamaran also has fastest to make the waste close to conveyor.

⎯The continuous flow of marine debris in the sea has been a problem until now. Previous research on garbage collection vessels was conducted in calm water conditions, without waves and waves due to wind. This is different from the real conditions in the sea which are choppy and bumpy. In addition, research on the effect of wave length and amplitude on marine debris collection on garbage collection vessels does not yet exist. This study aims to determine the effect of wave length and amplitude on velocity contours, flow patterns, and ship resistance. The ship uses a circular hollow wing conveyor. Modelling using Rhinocheros software, then numerical simulation using Computational Fluid Dynamic (CFD). Verification of the simulation process uses grid independent by varying the mesh size, then validation of the results is done by comparing with previous experimental research. The results show that the best velocity contour in front of the conveyor is at a ship speed of 1.028 m/s (2 knots) using an amplitude of 0.5 T and a wavelength of 0.5 L. The velocity value in front of the conveyor is 1.551 m/s. This affects the speed of collecting marine debris. This affects the speed of collecting marine debris. The model that has a laminar flow pattern at the bow and at the stern is a speed of 1 knot at an amplitude variation of 0.1 T and a wavelength of 0.1 L. This is the best because it is easy to collect garbage. The smallest drag is the speed of 0.514 m/s (1 knot) at amplitude variation of 0.1 T and wavelength of 0.1 L. At this condition, the fuel consumption is the least. Thus, the greater the wavelength and amplitude of the waves the greater the drag and the smaller the speed.
