Design of Monitoring Device for the Process of Organic Waste Decomposition into Compost Fertilizer and Plant Growth through Smartphones based on Internet of Things Smart Farming

Abstract

Based on data published by the Ministry of Living Environment and Forestry in 2020, Indonesia produces at least 93,200 tons of waste per day in various types of composition or around 34 million tons of waste per year. From the collection of waste, it could be used as compost fertilizer which is taken from leaf waste. From these problems, a device was designed that could monitor the decomposition process of organic waste into compost fertilizer. This device is equipped with a temperature sensor, humidity sensor, sensor of soil pH, soil moisture sensor, and color sensor to monitor the composting fertilizer process. The device could also detect plant growth as an indication that the compost fertilizer made is in good condition. Our device was used on the Internet of Things (IoT) and the blynk application as a monitoring application. From the test results, the temperature sensor's accuracy is 98.2%, the humidity sensor is 96.1%, the soil pH sensor is 95.26%, the soil moisture sensor is 98.55%, and the color sensor successfully detects the results of plant growth well. The design of this device is expected to invite the public to be wiser in sorting waste and using it for the surrounding environment.

Pembuatan Mesin Fermentator Pupuk Organik Cair untuk Menunjang Efektifitas Produksi Kelompok Tani di Desa Gucialit, Kabupaten Lumajang, Jawa Timur

“…POC merupakan larutan hasil dari pembusukan bahan-bahan organik yang berasal dari sisa-sisa tanaman, kotoran hewan, dan manusia yang kandungan unsur haranya lebih dari satu. POC lebih mudah diserap oleh tanaman karena senyawa kompleks yang terkandung didalamnya terurai dan berbentuk cair sehingga mudah diserap oleh tanaman melalui akar [8] . Pada umumnya, POC tidak merusak tanah dan tanaman dikarenakan POC tidak meninggalkan residu pada tanah dan tanaman.…”

Desain Alat Monitoring Real Time Suhu Tubuh, Detak Jantung dan Tekanan Darah secara Jarak Jauh melalui Smartphone berbasis Internet of Things Smart Healthcare

“…Berkenaan hal tersebut, maka dikembangkan dan dirancang sebuah alat monitoring terpadu suhu tubuh, detak jantung dan tekanan darah secara realtime dan dapat dimonitoring jarak jauh melalui smartphone berbasis Internet of Things (IoT) [5,6]. IoT merupakan suatu konsep dimana obyek dapat bertukar informasi satu sama lain melalui jaringan internet yang tersambung secara terus-menerus.…”
