Abstract

Inverter adalah salah satu alat elektronika yang digunakan untuk mengubah tegangan DC (Dirrect Current) menjadi tegangan AC (Alternating Current). Gelombang output dari suatu inverter dapat berupa gelombang sinus (sine wave), gelombang kotak (square wave), dan gelombang sinus modifikasi (modified sine wave). Inverter 1 fasa full bridge ini dirancang menggunakan teknik PWM berbasis mikrokontroler Arduino uno, optocoupler sebagai driver 4 MOSFET, transistor 9014 sebagai penguat tegangan inverter, serta rangkaian double boost converter sebagai penaik tegangan pengganti transformator. Inverter ini mengubah tegangan dari double boost converter sebesar 311volt DC menjadi 220volt AC dan menggunakan baterai berkapasitas 12V-35Ah sehingga mampu digunakan untuk menyalakan beban lebih lama. Tegangan output yang dihasilkan oleh double boost converter sebesar 316volt DC. Inverter ini mampu mengubah dari tegangan 316volt DC ke 288,1volt AC frekuensi 49,50 Hz dengan gelombang output berbentuk gelombang kotak. Inverter ini diaplikasikan pada pembangkit listrik tenaga floating hydro portable.

Abstract

Food security is an important aspect in maintaining people's welfare. However, the main challenge in managing pekarangan as a food source is the efficient management of water for watering plants. Sengkolo Makmur has a yard that is used for food security in the Josenan area of Madiun City. So far, watering is done manually using human power. This watering is also not scheduled so that if the owner of the yard is busy then watering cannot be done. The use of an automatic watering system in the yard has become an innovative solution in increasing the efficiency of water management and plant care. The research method used includes discussions with the management, prototype design, and field trials. This activity describes the steps for designing and developing an automatic watering system involving temperature sensors, water pumps, and time controllers. The watering system is also equipped with a time controller to adjust the watering time according to the needs of plants at various times and seasons. This activity can be a guide for Sengkolo Makmur sustainable food garden managers in applying smart technology for water conservation and developing a greener environment.

Abstract

A transformer is an electrical device that is used to change the voltage from one level to another in order to transfer electrical energy from one place to another. One of the main benefits of a transformer is to reduce power loss in the electrical network. Transformers can be used to stabilize the electric voltage and keep the electric voltage within safe limits. The protection system on the transformer is very important to prevent damage or failure to the transformer which can cause disruption of the electricity supply or even fire. This protection will work to cut off electrical connections and prevent damage to the transformer. Overload interference occurs if the current read on the Smart Relay LCD is more than 10 A so that the contactor will work after a disturbance of 5 seconds and the green indicator light will turn off. Whereas for Overheat interference on the transformer if the temperature exceeds 450C then the contactor will work to turn off the system with a duration of 1-2 seconds then the green indicator light and the system will OFF. The voltage drop disturbance occurs if the voltage read on the Smart Relay LCD is less than 15 kV on the primary side of the transformer and less than 300 V on the secondary side of the transformer so that the contactor will work to cut off the voltage after a disturbance occurs for 8-10 seconds then the green indicator light will turn off.
