Abstract

Optimization of transformer performance in distributing electrical energy is determining by transformer insulating oilquality. Insulating oil temperature increases with the great of transformer workload released during the distributionof electric power to consumers. Then, it will be affected to the breakdown voltage (BDV) value and oil quality whichcan even lead to the insulating oil failure. This research is carried out by taking a sampling of new deck oil and usedoil at different temperatures. Then insulating oil is tested by using BDV test and Dissolved Gas Analysis (DGA) todetermining furan value and workability of insulating oil lifetime. Thus, this research expected to identify the feasibilityof transformer insulating oil lifetime based on breakdown voltage and furan value.

Abstract

Tobacco is the main raw material used to make cigarettes. Increasing of cigarette sales which have continued until now has led to an increasing of tobacco produced by tobacco farmers. Region of East Java has the largest percentage of tobacco producers and most of the peoples that work as tobacco farmers. Some of them still carried out the chopping process manually, thus requires more energy and longer time. This research is carried out by chopping tobacco leaves that have been dried and stacked with a thickness of 4mm. The procedure is carried out by pressing the start button, then conveyor moves to bring the container to the chopper. The container which attached to the magnet will be stop and detected by the reed switch sensor. The conveyor rotation is controlled by a DC motor gearbox and the operation of the chopper blades is controlled by a power window motor. All the chopping process is controlled using PLC

Abstract

Dengan adanya IoT kita dapat mengontrol alat yang diinginkan dimana pun dan kapan pun hanya dengan melalui jaringan internet / WiFi. Penelitian ini bertujuan untuk merancang alat kontrol on - off pada lampu tanpa berkontak secara langsung menggunakan teknologi IoT. Pada jurnal ini dibahas proses dari awal sampai akhir pengaplikasian alat berbasis IoT. Pertama Node MCU ESP32 sebagai mikrokontroler yang telah terintegrasi dengan WiFi mode yang nantinya akan terkoneksi dengan Smartphone dan diteruskan pada Relay Module yang bertugas untuk memutus dan menghubungkan input tegangan pada Lampu. Modul ini harus diprogram dahulu menggunakan software Arduino untuk menghubungkan antara perangkat Smartphone dan Node MCU ESP32. Jika sudah selesai, kita koneksikan Node MCU ESP32 dengan WiFi, maka dengan mudah kita dapat mematikan dan menyalakan lampu rumah dimana pun melalui aplikasi Telegram.

Abstract

Baby incubator is a tool for maintaining the warmth of the baby after birth so they are able to adapt with external environment. The main feature of incubator is setup room temperature for maintaining baby’s temperature to avoid hypothermia. However, for premature babies it is not only strict temperature regulation, but also many procedures, such as monitoring their body weight regularly as the indicators to determine the development of baby’s health. Baby incubator with temperature and baby weight control system is needed to make it easier for paramedics to monitoring the baby’s progress while in the incubator. System design of incubator is designed with the room temperature controller ON-OFF system in the range of 30oC – 35oC and wight scale system in the range of 0 kg – 5 kg. Incubator box will be installed using blower 12VDC and heater driver. Temperature and weight controller system is designed using BASCOM-AVR software. This research is hoped that this simple incubator design can be applied to small-scale baby health centers, such as baby clinics and community health centers.

Abstract

Bawang Merah adalah sebuah bumbu masak tradisional berwarna merah yang berbentuk umbi. Bawang merah dapat menambah cita rasa masakan dan terasa pedas apabila dikonsumsi langsung. Selain sebagai bumbu masak, bawang merah juga memiliki kegunaan untuk obat tradisional. Bawang merah banyak dibudidayakan di wilayah Indonesia untuk memenuhi kebutuhan bumbu masak tradisional. Salah satu tempat budidaya bawang merah berada di dusun Ledok desa Pacet Kecamatan Pacet Kabupaten Mojokerto. Di daerah ini bawah merah setelah dipanen langsung dijual atau disimpan. Penyimpanan bawah merah tidak dapat dilakukan terlalu lama, karena kadar air bawang merah masih terlalu tinggi yang menyebabkan umbi bawang merah mudah rusak atau akan tumbuh tunas bila kondisi udara lembab. Adanya rumah pengering bawang (RPB) menjadi solusi dalam meningkatkan kualitas bawang merah, sehingga kadar air dapat diturunkan, sehingga bawang merah disimpan dalam waktu yang lama. Dalam pengabdian kepada masyarakat ini, implementasi instalasi listrik pada RPB dilakukan untuk menyediakan sumber energi listrik. Sumber energi listrik ini digunakan untuk mensuplai beban listrik pada RPB antara lain lampu, kipas angin (exhaust fan) dan beban lainnya. Adanya RPB ini yang sudah dilengkapi dengan instalasi listrik membuat masyarakat merasa sangat terbantu karena dapat dijadikan tempat untuk mengeringkan bawang merah dan RPB dapat dibangun dengan memanfatkan lahan yang tidak terlalu luas.
