Abstract

Abstract-Widarapayung Wetan Village is developing a village that applies technology as well as an educational tourism object. Technology tourism combined with agriculture to become modern agricultural tourism. One of the applied agriculture is spinach cultivation so that the results from agriculture can be developed into a food product such as spinach chips. Hydroponic greenhouses that use Internet of Things technology can be used for modern agricultural implementation. Monitoring systems and automatic control systems will be able to assist in the maintenance of spinach cultivation. The application of modern agriculture is expected to add insight to the surrounding community. In addition, the greenhouse with this technology is expected to be an attraction to provide knowledge to visitors and the public as educational and technology tourism. The tour can introduce the planting process, controlling the environment around the plants using sensors and monitored through the website. The stages undertaken include constructing a green house framework, establishing a monitoring system, and placing the greenhouse at the destination location or related partners. In addition, further activities include manufacturing hydroponics, manufacturing and assembling control systems, as well as training on the use and maintenance of hydroponic greenhouses.

Abstract

Solar energy is a new renewable energy (EBT) that can be used as an alternative energy source for electricity generation to replace fossil fuels or supplies from the National Electricity Company (PLN). One of its uses can be applied in everyday life in household appliances, namely, coconut grater machines. Coconut grater machines used in the market still use fossil fuels to crush coconut meat, so solar energy is implemented as an alternative energy to operate the coconut grater machine. The use of solar panels in this study is highly dependent on sunlight exposure. In addition, the tilt position of the solar panel can also determine the power generated by the solar panel. The tilt position of the solar panel can be manually adjusted according to the direction of sunlight at certain times. Around midday, sunlight can be captured optimally. At that time, the accumulator/battery will quickly charge, and the coconut grater machine can be used at low or high speeds. The purpose of this study is to implement a PWM (Pulse Width Modulation) system-based control as a motor speed regulator on a coconut grater machine. PWM technology is installed to obtain optimal rotation results and has the potential to save electrical energy. The research results showed that the installed solar panels could produce an average of 4.86 watts of electrical power at 8:00 a.m. WIB and a maximum of 5 watts of electrical power at 12:00 p.m. WIB. Under no-load operating conditions, the current was 0.38 A and the motor speed was 3,724 Rpm. When the engine was tested under load, the speed was 2,926 Rpm.

Abstract

Termoelektrik merupakan suatu alat yang berbentuk modul atau peltier, yang dapat secara langsung mengubah energi panas menjadi energi listrik. Termoelektrik dapat dibangkitkan dengan memanfaatkan proses pembakaran biomassa pada tungku. Energi panas dari hasil pembakaran biomassa digunakan sebagai energi primer untuk membangkitkan generator termoelektrik. Pada penelitian ini, dilakukan pembuatan biomassa dari limbah kulit pisang dan daun kering dengan enam jenis briket. Komp    osisi jenis briket terbagi menjadi, jenis A (dengan perbandingan 20% perekat: 60% kulit pisang: 40% daun kering), jenis B (dengan perbandingan 20% perekat: 50% kulit pisang: 50% daun kering), jenis C (dengan perbandingan 30% perekat: 30% kulit pisang: 70% daun kering), jenis D (briket arang batok kelapa), jenis E (briket arang bambu), dan jenis F (briket arang kayu). Pembakaran briket maksimal adalah briket jenis D (briket batok kelapa) dengan tegangan 19,88 V dan arus 0,19 A pada perbendaan suhu (ΔT) 80oC. Pembakaran briket terendah adalah briket jenis A dengan tegangan 12,55V dan arus 0,12A pada perbedaan suhu (ΔT) 30oC. Sedangkan daya terbesar untuk modul termoelektrik adalah sebesar 3,76 Watt/Jam dengan spesifikasi aki 12V, 7.2Ah. Sehingga untuk melakukan pengisian aki dibutuhkan waktu 22,9 jam.
