Abstract

B20 is a fuel that is widely used for combustion systems in diesel engines, especially in Indonesia. 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.

Abstract

Mesin diesel merupakan salah satu jenis mesin pembakaran internal yang sangat diperlukan dalam kehidupan manusia saat ini. Teknologi mesin diesel terus berkembang hingga saat ini. Namun mesin diesel sangat bergantung pada bahan bakar diesel fosil, sedangkan stok bahan bakar fosil semakin berkurang. Berkaitan dengan fenomena tersebut, maka dilakukan penelitian dengan tujuan mengaplikasikan heat recovery jacket cooler berbasis fuel heater dan menganalisis besarnya konsumsi bahan bakar. Penelitian ini menggunakan metodeeksperimental antara lain pembuatan instalasi fuel heater dan pengukuran konsumsi bahan bakar. Pada percobaan menggunakan bahan bakar biodiesel (B20) dengan variasi temperatur 30oC, 35oC, 40oC, 45oC, dan 50oC. Mesin diesel yang digunakan dalam penelitian ini adalah mesin 4 langkah, 4 silinder, 1500 rpm 18 kVA dan mesin diesel dalam kondisi tanpa beban. Hasil penelitian menunjukkan bahwa semakin tinggi temperatur bahan bakar semakin menurun konsumsinya, sehingga dapat disimpulkan bahwa pemanasan bahan bakar mempengaruhi efisiensi konsumsi bahan bakar.Kata kunci: Mesin Diesel; Konsumsi bahan bakar; Pemanas; Pendinginan Jaket;

Abstract

Cultivating vannamei shrimp using round ponds is an alternative way of cultivation to minimize the significant investment costs. 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. Keywords : cultivation, energy, optimization, pv panel, shrimp
