    ABSTRAKGapoktan Lembang Agri merupakan contoh kelompok tani yang sukses dalam mengembangkan bisnis pertanian sehingga menjadi contoh bagi kelompok tani lainnya. Gapoktan Lembang Agri mulai menerapkan teknologi Smart Farming di lahannya. Namun teknologi tersebut masih terlalu mahal untuk digunakan oleh kelompok tani lainnya. Atas kepeduliannya dalam menyebarkan teknologi Smart Farming kepada kelompok tani lainnya, maka Gapoktan Lembang Agri bekerjasama dengan Itenas Bandung untuk membuat beberapa teknologi terkait yang ekonomis. Salah satu teknologi yang dibuat adalah penyiraman tanaman otomatis berbasis IoT. Alat ini menggunakan mikrokontrol ESP32 dengan aplikasi Arduino IoT Cloud yang terhubung ke internet melalui router/Wifi di gedung packing house Lembang Agri yang terletak di samping lahan pertanian. Penyiram tanaman otomatis ini memantau kelembaban tanah dengan Capacitive Soil Moisture Sensor, kelembaban dan temperatur lingkungan dengan sensor DHT11, serta penggunaan solenoid valve dan modul relay dalam mengalirkan fluida untuk penyiraman tanaman. Sumber daya dari alat yang dipasang di lahan diperoleh dari rangkaian baterai 18650 yang dapat diisi ulang (charge). Hasil uji fungsionalitas alat diperoleh bahwa nilai kelembaban tanah, temperatur dan kelembaban udara telah dapat dipantau melalui internet menggunakan smartphone. Solenoid valve telah berfungsi pada batas kelembaban yang ditentukan melalui program. Namun terdapat delay/keterlambatan sekitar 3 detik dalam beraksi. Hal ini diakibatkan oleh kecepatan jaringan internet yang tersedia. Hasil uji lapangan belum diperoleh karena masih dalam proses. Atas pencapaian uji fungsi alat ini, telah dilaksanakan beberapa kali pelatihan terkait alat ini ke berbagai kalangan masyarakat yaitu: para petani milenial, guru/dosen, mahasiswa dan siswa.Kata kunci: smart farming, capacitive soil moisture sensor, DHT11, ESP32, solenoid valveABSTRACTGapoktan Lembang Agri is an example of a successful farmer group in developing an agricultural business, thus becoming an example for other farmer groups. Gapoktan Lembang Agri has started implementing Smart Farming technology in its land. However, the technology is still too expensive for other farmer groups to use. For their concern in spreading Smart Farming technology to other farmer groups, the Lembang Agri Farmers Association collaborated with Itenas Bandung to create several related technologies that more affordable. One of the technologies created is IoT-based automatic plant watering. This tool uses an ESP32 microcontroller with the Arduino IoT Cloud application which is connected to the internet via a router/Wifi in the Lembang Agri packing house building which is located next to agricultural land. This automatic plant sprinkler monitors soil moisture with a Capacitive Soil Moisture Sensor, ambient humidity and temperature with a DHT11 sensor, as well as the use of a solenoid valve and a relay module in flowing fluid for watering plants. The power source of the ground-mounted device is obtained from rechargeable 18650 batteries. The results of the tool's functionality test showed that the value of soil moisture, temperature and humidity can be monitored via the internet using a smartphone. The solenoid valve has functioned at the humidity limit, specified by the program. But there is a delay of about 3 seconds in action, this is caused by the speed of the available internet network. Field test results have not been obtained because they are still in process. For the achievement of the function test of this tool, several trainings related to this tool have been carried out to various circles of society, namely: millennial farmers, teachers/lecturers, college students and students.Keywords: smart farming, capacitive soil moisture sensor, DHT11, ESP32, solenoid valv

    Stress Simulation of Chassis Crossover Electric Vehicle

    The development of an electric vehicle chassis is one step in the design process of a vehicle, especially for crossover vehicles that are being designed. The chassis design of the vehicle must have a chassis that is solid and can sustain all the loads that occur on the chassis, such as passenger loads, electric motors and so on. In the chassis design process, stress analysis is needed to verify the strength of the chassis if the loads that are applied. Stress analysis begins with making an initial model of an existing chassis using CAD then stress analysis using FEA Solidworks software. Stress analysis includes static and crash load. The results of the analysis under static load conditions obtained a maximum stress that occurs at 206 MPa, a factor of safety = 1.69, and a deflection of 0.4 mm where the chassis deflection due to bending is less than 1 mm. Keywords: chassis, EV, strength simulation, FEA

    ABSTRAKDesa Cikiray belum mempunyai tempat pembuangan akhir sampah sehingga masyarakatnya membuang sampah rumah tangga ke sungai, lembah maupun dibakar di tempat-tempat terbuka. Hal tersebut mengakibatkan pencemaran lingkungan. Untuk itu masyarakat Desa Cikiray perlu dibekali pengetahuan dan keterampilan mengenai pengelolaan sampah rumah tangga. Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan pelatihan pengelolaan sampah rumah tangga kepada masyarakat Desa Cikiray serta membuat mesin press untuk memadatkan sampah non organik yang akan dijual ke pengepul. Peserta kegiatan ini adalah ibu-ibu Pemberdayaan Kesejahteraan Keluarga (PKK) dan staf Desa Cikiray. Selain teori, pada pelatihan ini juga dilakukan praktek pengolahan sampah rumah tangga. Hasil pelatihan menunjukkan bahwa ada peningkatan pengetahuan dan keterampilan masyarakat Desa Cikiray dalam pengelolaan sampah rumah tangga.Kata Kunci: Desa Cikiray, sampah rumah tangga, mesin press ABSTRACTIn general, household waste produced by people in rural areas is disposed of in rivers and valleys or burned in open areas, creating environmental pollution problems. Waste management is a problem often found in villages that do not have a landfill, one of which is Cikiray Village, Sukabumi Regency. It is important to provide waste management training and a press machine for managing waste in order to separate organic and non-organic waste in Cikaray Village. This activity's participants came from Family Welfare Programme and Cikaray Village staff. This training provided theoretical aspects and carried out the practice of processing household waste. The result showed an increase in the knowledge and skills of the people in Cikaray Village in managing household waste.Keywords: Cikiray Village, household waste, garbage machin

    ABSTRAK Crawler track merupakan sistem roda rantai pada kendaraan yang difungsikan untuk dapat melalui berbagai kondisi jalan yang sulit dilalui kendaraan beroda. System Crawler track dapat diterapkan pada kendaraan ringan yang digunakan untuk transportasi pada daerah yang mempunyai jalan yang sulit dilalui. Pada kendaraan system tersebut diperlukan komponen frame yang mampu menahan beban-beban kendaraan. Tujuan dari penelitian ini adalah untuk merancang Frame crawler track pada kendaraan ringan untuk dapat melewati jalan berkontur tanah.
