One of the obstacles in vannamei shrimp cultivation is the availability of Dissolve Oxygen (DO) in water. By utilizing solar energy which is converted into electrical energy, DO levels can be maintained with an aeration system that utilizes solar energy. North Lombok Regency has the potential for solar energy which reaches 4.91 kWh / m2 / day with a minimum clearness index of 0.446 which is very potential to be utilized. The purpose of this research is to find the optimal design for a stand alone panel PV system to serve the electrical energy needs of vannamei shrimp farming in round ponds. The method used is to calculate the most optimal design with HOMER (Hybrid Optimization Model for Electric Renewables) software to be able to serve the average energy requirement of 38.2 kWh / day. From the analysis, it was found that the most optimal designs were the PV panel brand A 16.8 kW, the PV panel brand B 1 kW and the 200 Ah battery with a total of 104 units.

Apart from having the advantages, biodiesel B20 also has various disadvantages that affect the performance of diesel engines such as those that have a higher flash point than diesel so that biodiesel is more difficult to burn and has a high viscosity which causes less good atomization of fuel and eventually causes deposits in combustion chamber. One or the solution to the problem is that it can be done carefully. The aim of this research is to make a Shell and Tube Heat Exchanger (STHE) by including the insulation in it to improve the heat exchange performance. The method applied in this research is an experiment by testing the performance of the heat exchanger using a cooling water jacket. Some of the equipment used is a diesel engine from the Mitsubishi Diesel Engine, Type 4d35, 4 cylinder, 75 HP. Data were collected at a constant rotation of 1500 rpm at no load. The results showed that the higher the cooling water temperature of the jacket, the higher the biodiesel temperature. With a cooling water jacket temperature of 83oC, it can heat biodiesel at 74.8oC.

The shipyard uses a slipway type construction or a pull dock that uses an electric winch. The large number of ship repair requests at Bitung Marine and Fisheries Polytechnic shipyard is the reason for the need to increase the capacity of the shipyard.

This research was carried out from June to August 2021 using the case study method and analyzed by calculating the TCC value (technological contribution coefficient) of the technological components of technoware, humanware, infoware and orgaware.

(2) record the type and amount of catch. The flying bottom longline (RDL) in this study is a modified construction design of bottom long line, by shortening the branch line and reducing its distance on the main line. The fishing method was changed by spreading the main line on the bottom of the sea. Thus each branch line and hooks will float to the mid surface by taking advantage of the movement of the ocean currents. The research was conducted in August-October 2020 in the waters of the Lembeh Strait, Bitung City, North Sulawesi. The research method used was 6 fishing trips trials. The results of this study indicate that the normality and homogeneity test of the hook rate data distribution is obtained 0.635 for residual value of data normality and a 0.732 of residual value of homogenity, so the data is normally distributed and homogeneous The hook rate on the flying bottom longline (RDL) operated at a depth of 10 m with fresh squid fish bait illustrates that the flying bottom longline hook rate (RDL) is higher than the conventional bottom longline (Rdk).
