Abstract

Various studies and research have been conducted to find alternatives to liquid insulation. One that is considered the most potential is vegetable oil since it has various advantages, including non-toxic, biodegradable, renewable waste products due to reactions in the form of CO2 and water, high flash points, and better thermal characteristics. In this study, Palm Oil Mill Effluent (POME) was used as the raw material for insulation oil with the addition of an additive in the form of nano-silica, which improves the quality of the insulation oil. As for determining the feasibility of insulation oil, characteristic tests were carried out in the form of density, viscosity, moisture content, acid number, pour point, flash point, and breakdown voltage. Based on the results of the tests, it was obtained that the lowest density in pure oil was 0.8757 g / cm³, the lowest viscosity in oil with the addition of 0.13 wt% nano-silica was 4.0248 cSt, and the lowest acid number in pure oil was 0.5797 mgKOH / g. It was also discovered that the pour point value is the same for each sample, the moisture content is 0.05%, the flashpoint is > 104 °C, and the breakdown voltage is ≥ 60 kV for each sample. The data show that the insulation oil made from POME has the potential to be used as an alternative to insulation oil.

Abstract

ABSTRAKPenyebaran Covid-19 dapat diminimalisir dengan bebeberapa cara diantaranya penyemprotan antiseptik. Tujuan penelitian ini menghasilkan robot yang berguna meminimalisir penyebaran Covid-19 dengan sistem kontrol otomatis menggunakan Arduino Uno R3 serta panel surya yang dikoneksikan dengan sistem IoT (Internet Of Things). Penelitian ini menggunakan metode penelitian yang terdiri dari empat tahapan: 1). Mendesain (merancang) alat, 2). Tahapan pembuatan alat, 3). Tahapan ujicoba alat, 4) Tahapan analisis alat. Ketika ada benda yang berada pada titik atau jarak tertentu maka sensor ultrasonik akan mendeteksinya dan akan mengirimkan sinyal ke mikrokontroler selanjutnya robot akan bekerja kembali seuai perintah dari android. Hasil pengujian saat ada obstacle dengan nilai v= 11,40 Volt di dapat nilai acuan pengukuran dan nilai hasil pengkuruan memiliki nilai rentang error tertinggi pada saat nilai acuan 55 cm dan nilai hasil pengukuran 52 cm. Pengujian RPM pada roda kiri posisi (maju) nilai tertinggi sebesar 40,0 RPM dan roda kanan 39,7 RPM.Kata kunci: Arduino, robot, android, IoT, Covid-19, panel surya ABSTRACTThe spread of Covid-19 can be minimized in several ways, including spraying antiseptics. The purpose of this research is to produce a robot that is useful for minimizing the spread of Covid-19 with an automatic control system using Arduino Uno R3 and solar panels that are connected to the IoT (Internet Of Things) system. This study uses a research method consisting of four stages: 1). Designing (designing) tools, 2). Stages of making tools, 3). Stages of testing tools, 4) Stages of tool analysis. When there is an object that is at a certain point or distance, the ultrasonic sensor will detect it and will send a signal to the microcontroller then the robot will work again according to the command from the android. The test results when there is an obstacle with a value of v = 11.40 Volts the measurement reference value is obtained and the measurement result value has the highest error range value when the reference value is 55 cm and the measurement value is 52 cm. RPM testing on the left wheel position (forward) the highest value of 40.0 RPM and the right wheel 39.7 RPM.Keywords: Arduino, robot, android, IoT, Covid-19, solar panels
