Abstract

Kebutuhan pakan ternak di pedesaan sering terkendala oleh proses pencacahan rumput yang masih manual dan tidak efisien. Penelitian ini merancang mesin pencacah rumput berbasis motor DC yang digerakkan panel surya serta dilengkapi kendali Internet of Things (IoT) menggunakan Sonoff SV. Sistem terdiri atas panel surya 50 Wp, solar charge controller, dua akumulator SMT1212, dan motor DC 12 V–3000 rpm dengan pisau pencacah ganda. Hasil pengujian menunjukkan mesin mampu mencacah beban hingga 3000 g dengan penurunan kecepatan putar hanya 4%, serta menghasilkan 39,05% cacahan berukuran 2–5 cm sesuai standar SNI pakan ternak. Tegangan baterai relatif stabil, sedangkan arus meningkat seiring bertambahnya beban. Temuan ini membuktikan bahwa mesin pencacah rumput tenaga surya berbasis motor DC efisien, ramah lingkungan, dan aplikatif bagi peternak di wilayah minim listrik.

Abstract

Solar photovoltaic (PV) technology, which converts sunlight into electrical energy, is an environmentally friendly applied technology. PV installation on the roof of a building, also known as Rooftop PV, is used not only as a heater but also as an alternative source of electrical energy for a building. Rooftop PV on the Mushola Baiturrohim is used as a backup source of electrical energy when PLN cannot supply voltage. The installed 100 Wp solar photovoltaic system is capable of providing power to a setup consisting of 3 lamps, each with a wattage of 15, and a fan with a diameter of 12 inches, for approximately 2.5 hours. Socialization of the assembly and maintenance of the Rooftop PV system is also carried out for the management of the prayer room and the surrounding community, as a means of transferring renewable energy knowledge that all can utilize.

Abstract

A night light is a low-intensity lighting device designed to provide visual comfort in the dark. The research methodology includes designing an electronic circuit, placing the LDR sensor as an input element, and testing the system's effectiveness at various light levels. Parameters analyzed include the sensor's reaction to changes in light, the system's reliability in turning the light on and off, and its energy efficiency. The test results indicate that the system can operate automatically and stably, with a fairly good response to fluctuations in ambient light intensity. The lamp is optimally activated in dark situations and deactivated when exposed to bright light, providing the potential to improve energy efficiency and user comfort. Thus, an automatic night light using an LDR sensor can be a practical, economical, and simple choice for everyday use.
