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.

Abstract

This article discusses a preliminary study of developing a paddlewheel aerator for shrimp ponds using an integrated intelligent aquaculture system to support intensification. Two paddlewheel aerators with different phases have been successfully installed. The test was carried out on two different types of motors, which were intended to comprehend the performance of every motor on a paddlewheel aerator. The ratio of the speed values for a single-phase motor was 102 rpm and for a 3-phase motor was 110.3 rpm. The data from the performance observation of the aeration wheel motor can be viewed via a smartphone using a website application. The data displayed from the observations are in the form of data on voltage, current, frequency, power, power factor, and the power generated by the pinwheel motor. The test results show the performance of the aeration wheel motor that works under normal conditions with an average measurement error of 0.23%, below the acceptable error limit of 0.5%. This research forms the basis for a smart aquaculture system that can be developed domestically to support local industries in Indonesia.

Abstract

Pemahaman pengelolaan limbah dan sumber daya alam merupakan salah satu aspek yang mempengaruhi terwujudnya kelestarian lingkungan. Pada kegiatan pengabdian masyarakat ini mengadakan forum dan pelatihan pengelolaan limbah dan sumber daya manusia untuk mewujudkan lingkungan lestari dan berkelanjutan. Kegiatan ini menggunakan metode sharing session dan diskusi dalam forum dengan menampilkan kondisi pengelolaan limbah dan sumber daya di Taiwan sebagai acuan pembanding untuk mengelola limbah dan sumber daya di Indonesia. Peserta forum pelatihan sebanyak 100 orang yang terdiri dari dosen akademisi dari 3 perguruan tinggi yaitu Politeknik Perkapalan Negeri Surabaya, Institut Teknologi Adhi Tama Surabaya dan Chung Yuan Christian University, serta pihak industri. Analisis data kuisioner pemahaman pengelolaan limbah dan sumber daya menggunakan metode Boxplot skor dan Paired t test. Hasil kegiatan ini menunjukkan bahwa terjadi peningkatan pemahaman dalam mengelola limbah dan sumber daya. Tingkat pemahaman ini akan mendukung terwujudnya kelestarian lingkungan yang berkelanjutan.
