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

Abstract

Pemanfaatan energi terbarukan menjadi salah satu solusi strategis dalam mendukung teknologi ramah lingkungan, khususnya untuk penanganan permasalahan sampah di perairan. Penelitian ini bertujuan untuk menganalisis kinerja sistem Pembangkit Listrik Tenaga Surya (PLTS) yang diterapkan pada prototipe robot pengangkut sampah perairan. Metode penelitian yang digunakan adalah eksperimental kuantitatif, dengan melakukan pengukuran langsung terhadap parameter kelistrikan sistem, meliputi tegangan, arus, dan daya keluaran panel surya, serta kinerja sistem pengisian baterai. Sistem PLTS terdiri atas panel surya polikristalin berkapasitas 10 Wp, solar charge controller tipe PWM, dan baterai VRLA 12 V sebagai penyimpan energi. Hasil pengujian menunjukkan bahwa kebutuhan daya total robot sebesar 27,82 W, dengan arus operasi sekitar 2,28 A pada tegangan baterai 12,2 V, sehingga robot mampu beroperasi selama ±1 jam per siklus kerja. Panel surya menghasilkan daya maksimum sebesar 7,70 W pada kondisi cuaca cerah sekitar pukul 11.00 WIB, sedangkan solar charge controller mampu menjaga kestabilan tegangan pengisian pada 14,4 V dengan daya keluaran maksimum mencapai 20,73 W. Hasil analisis menunjukkan bahwa sistem PLTS mampu mendukung operasional prototipe robot melalui mekanisme pengisian baterai, namun kapasitas panel surya masih memiliki keterbatasan untuk suplai daya langsung. Penelitian ini diharapkan dapat menjadi dasar pengembangan sistem PLTS yang lebih optimal pada aplikasi robot lingkungan perairan. The utilization of renewable energy represents a strategic solution to support environmentally friendly technologies, particularly in addressing waste problems in aquatic environments. This study aims to analyze the performance of a Solar Power Generation System (SPGS) applied to a prototype of an aquatic waste-collecting robot. A quantitative experimental method was employed by conducting direct measurements of the system’s electrical parameters, including voltage, current, and power output of the solar panel, as well as the performance of the battery charging system. The SPGS consists of a 10 Wp polycrystalline solar panel, a PWM-type solar charge controller, and a 12 V VRLA battery as the energy storage unit. The experimental results indicate that the robot requires a total power of 27.82 W, with an operating current of approximately 2.28 A at a battery voltage of 12.2 V, enabling the robot to operate for approximately 1 hour per working cycle. The solar panel produced a maximum power output of 7.70 W under clear weather conditions at around 11:00 a.m., while the solar charge controller successfully maintained a stable charging voltage of 14.4 V with a maximum output power of 20.73 W. The performance analysis shows that the SPGS is capable of supporting the robot’s operation through battery charging; however, the solar panel capacity remains insufficient for direct power supply. This study provides a foundation for further optimization of solar power systems in aquatic environmental robotics applications.
