Abstract

Kegagalan isolasi peralatan listrik tegangan tinggi merupakan permasalahan utama yang dihadapi oleh penyedia jasa ketenagalistrikan, khususnya dalam menjaga keandalan penyaluran tenaga listrik. Salah satu factor penyebab kegagalan isolasi pada peralatan tinggi adalah efek korona yang mengakibatkan peralatan tenaga listrik mengalami kerusakan. Tujuan dari kegiatan penelitian ini adalah mengintegrasikan beberapa sensor untuk mendeteksi tanda tanda peralatan jaringan distribusi yang telah mengalami fenomena korona melalui pengamatan frekuensi, sinar UV, dan kadar gas ozon. Data masukan dari sejumlah sensor akan diproses oleh mikrokontroler dan melalui koneksi nirkabel Internet of Things akan ditampilkan melalui layar HMI Nextion di lokasi berbeda dan jika nilai yang dideteksi melebihi nilai referensi, mikrokontroler menginstruksikan alarm buzzer berbunyi. Hasil penelitian menunjukkan bahwa prototipe alat pendeteksi korona mampu mengidentifikasi nilai kadar ozon sebesar 35 ppb, frekuensi desis rata rata sebesar 157 dB, serta spektrum cahaya UV sebesar 336 nm. Frekuensi desis peralatan akibat korona dan spektrum cahaya yang terbentuk telah melewati ambang batas standar. Kondisi tersebut telah memenuhi 2 dari 3 parameter yang menunjukkan bahwa peralatan distribusi telah mengalami efek korona.

Abstract

Indonesia's tropical climate and high rainfall frequently lead to unnoticed river overflows, causing significant health and economic losses. A Flood Early Warning System (EWS) using LoRa communication and an Arduino Mega2560 microcontroller was developed, incorporating ultrasonic, DHT11, rain gauge, and anemometer sensors to measure water level, temperature, humidity, rainfall, and wind speed. Unlike previous systems, it applies fuzzy logic for improved accuracy by considering rainfall and wind speed. Sensor errors ranged from 2.14% to 3.19%, with data transmission to ThingSpeak taking 11 seconds (99.94% accuracy) and to a website averaging 15.03 seconds. Fuzzy logic enhanced the system's warning accuracy.

Abstract

The majority of the population of Banjarwaru Village are farmers. The price of fertilizer is getting higher from time to time while farmers need fertilizer for their plants. Problems arise when fertilizer shortages often occur. In addition, the type of fertilizer used is generally a type of chemical fertilizer that is not good for the human body because the substance can be carried into the food consumed. Organic fertilizer is one option to overcome this problem. This type of fertilizer is now starting to be widely available on the market, although the price is relatively expensive. The solution to this problem is that it can be done by making organic fertilizer independently. Another factor is that there is a lot of organic waste that can be processed into liquid organic fertilizer (POC). Therefore, to create a village that is independent in fertilizer, the PKM Team aims to create an organic fertilizer maker based on a PLTS electricity source and provide training in operating the tool. The method used is by making an organic liquid fertilizer maker, socializing it to residents of Banjarwaru Village, and training and demonstrating how to operate the tool.
