Abstract

The strength construction to know the reaction that received in the construction to keep froma load, this aims to determine the safety and security of a construction. This research willfind equivalent stress value from a main engine foundation because loading from mainengine weight and main engine operation to customized with Class standard and to findsafety factor value. The load modelling will use Ansys Workbench 17.2, the method will useto analisys is a Finite Element metode to find stress value. This method will be used whendoing meshing in the Ansys Software. Meshing used size meshing 700 mm and fine for typemesh. The result have got the maximum stress value occurs at main engine Trial Conditionswith power at 100% got 237,8 MPa. Of All conditions analysis that have done have safetyfactor exceed than 1, maximum safety factor got 1,144 when main engine trial condition, sothis constructions confirmed safety construction. Then, maximum equivalent stress notpermitted exceed 264,37 MPa because it regulated from Class. Critical Area will receive inthe frame number 22.

Abstract

This article mainly describes vibration on new ship’s main engine foundation. The highamplitude of vibration could damage ship’s hull structure and disturb ship’s passenger. The amplitudecan be reduced by adding damping in the main engine foundation. Thereby in this article, modellingthe matemathic equation to get the vibration response. In matemathic equation a software calledMATLAB is used to determine the best graphic response. The stiffness equivalen in the main enginefoundatioon is 1,29 × 106????/????????.In this article use two damping variastion. The first point graphicshow the displacement of main engine foundation in the amount of 0.3 mm on time 0 sec, The secondpoint o graphic show the displacement of main engine foundation in the amount of 0.278 mm on time 0sec, The third point graphic show the displacement of main engine foundation in the amount of 0.299mm on time 0 sec.

Abstract

Savonius wind turbine have the lowest efficientcy compared to other wind turbines. Based on the previous research, additional interfering cylinder and fin to the turbine was less efficient so there is still an opportunity to improved. Based on this condition, the experimental study was carried out by adding 1 fin to each turbine blade and placing an interfering cylinder in front returning blade to determine its improvement. It aslso compared between both of them in the experimental also used the myring equation n=1. Wind turbine dimension was 40 cm and variation of interfering cylinder diameter ratio was ds/d = 0,4;0,5;0,6; and 0,7. The speed variation was 5 m/s, 6 m/s and 7 m/s. The best performance of the savonius myring n=1 wind turbine is obtained at ds/d = 0,4 at a speed of 6 m/s. The coefficient of torque (Ct) performance increase 21.47% and the coefficient of power (Cp) 89.80%

Abstract

Biodiesel is a renewable fuel and is generally made from biological sources (vegetable and animal)and is environmentally friendly. Raw materials that can be used as biodiesel are palm oil, olive oil, andcanola oil. In this research, the mixing of the three raw materials into a composition (multi-feedstockbiodiesel) was carried out through the process of mixing biodiesel with HSD to produce B20, B35 andB100 fuel. This fuel will be tested on a four stroke diesel engine with a 1000 watt light load, as well asdata collection with variations of 900 rpm, 950 rpm, 1000 rpm and 1050 so that the most optimal testresults for power and torque are obtained, namely B100 while for gsfc test results the most optimal fuelis obtained, namely B35.
