Abstract
Penyiraman merupakan salah satu aspek penting dalam budidaya bawang merah. Selain untuk pertumbuhan dan pembentukan umbi, penyiraman dapat mencegah penyakit akibat tumbuhnya jamur dan bakteri yang biasa muncul dimusim hujan. Pada umumnya petani masih menggunakan cara manual dengan ember untuk penyiraman sehingga membutuhkan banyak waktu, tenaga, serta kelelahan tinggi akibat kerja yang tidak ergonomis. Pada penelitian ini dilakukan usaha perbaikan kerja dengan mengaplikasikan mesin penyiram bawang merah berupa remote control (RC) boat. RC boat menggunakan radio control Fly Sky FS-T6 sebagai pengendali, pompa York DC 12 volt dengan suber energi baterai LiPo 3s 12 volt 5200 mAh, serta penggerak berupa motor brushless DC dengan sumber energi baterai LiPo 3s 12 volt 2200 mAh. Pengujian RC boat dilakukan pada lahan bawang merah yang memiliki petak dengan panjang 1,2 m, lebar 5,26 m, dan ketinggian 0,4 m, serta saluran drainase dengan lebar 0,5 m dan kedalaman air 0,22 m. Dilakukan pengujian kinerja pompa meliputi kapasitas, head, konsumsi daya, serta efisiensi pompa. Dilanjutkan pengujian mesin RC boat meliputi kapasitas kerja lapang, konsumsi daya mesin, serta hasil penyiraman berupa keseragaman dan kelembaban tanah. Berdasarkan pengujian pompa diperoleh kapasitas sebesar 48,24 l/mnt dengan head total 1,511 m. Pompa dapat bertahan selama 26,3 menit. Namun, kapasitas pompa tidak sebanding dengan daya input pompa sehingga nilai efisiensinya kecil yaitu 21,42% . Hal ini diakibatkan kerugian mekanis pompa, kondisi baterai, maupun kondisi zat cair. Pada pengujian mesin RC boat diperoleh hasil kecepatan gerak maju paling sesuai yang dapat memenuhi kebutuhan air bawang merah yaitu sebesar 0,146 m/s (skala 2) yang menghasilkan kedalaman curah 4,56 mm dan penambahan kelembaban tanah sebesar 35,8%. Pada kecepatan ini, baterai dapat bertahan selama 5,3 jam. Namun, nilai efisiensi lapang dan keseragaman distribsi air masih tergolong kecil. Dengan nilai KLE 0,083 ha/jam dan KLT 0,121 ha/jam menghasilkan efisiensi lapang sebesar 68,35%. Hal ini disebabkan oleh terbuangnya waktu akibat kondisi lahan dan kurangnya pemanfaatan lebar kerja alat. Sedangkan nilai keseragaman distribusi air yaitu 66,88%. Hal ini disebabkan oleh jenis sprayer, kehilangan tekanan, maupun kondisi air yang dapat menghambat penyiraman
English Abstract
Watering is one of the important aspects in shallot cultivation. In addition to the growth and formation of tubers, watering can prevent diseases caused by the growth of fungi and bacteria that usually appear in the rainy season. In general, farmers still use the manual method with buckets for watering so it takes a lot of time, energy, and high fatigue due to work that is not ergonomic. In this study, an effort to improve work was carried out by applying a red onion sprinkler machine in the form of a remote control (RC) boat. The RC boat uses a Fly Sky FS-T6 radio control as a controller, a 12 volt York DC pump with a 12 volt 5200 mAh LiPo 3s battery as a source of energy, and a brushless DC motor with a 12 volt 2200 mAh LiPo 3s battery as a source of energy. The RC boat test was carried out on shallot fields with a plot of 1.2 m long, 5.26 m wide, and 0.4 m high, as well as a drainage channel with a width of 0.5 m and a water depth of 0.22 m. Pump performance tests were carried out including capacity, head, power consumption, and pump efficiency. It was continued by testing the RC boat engine including field work capacity, engine power consumption, and the results of watering in the form of uniformity and soil moisture. Based on the pump test, the capacity of the pump is 48.24 l/min with a total head of 1.514 m. The pump can last for 26.3 minutes. However, the pump capacity is not proportional to the pump input power so that the efficiency value is small, namely 21,42%. This is due to mechanical losses of the pump, the condition of the battery, and the condition of the liquid. In testing the RC boat engine, the results of the most suitable forward speed that can meet the water needs of shallots are 0.146 m/s (scale 2) which results in a bulk depth of 4.56 mm and an additional soil moisture of 35.8%. At this speed, the battery can last for 5.3 hours. However, the value of field efficiency and uniformity of water distribution is still relatively small. With a KLE value of 0.083 ha/hour and KLT 0.121 ha/hour, the field efficiency was 68.35%. This is caused by wasted time due to land conditions and the lack of utilization of the working width of the tool. While the uniformity value of water distribution is 66.88%. This is caused by the type of sprayer, loss of pressure, and water conditions that can inhibit watering.
