Abstract

Garbage is one of the causes of environmental pollution. In waste disposal, people usually combine metal and non-metal waste in one place so that the quality of environmental health decreases. This study aims to create a portable smart trash can with Metal & Non Metal separator. This research is an experimental research conducted through two stages, namely the design stage and the testing stage. This system consists of metal detector, ultrasonic sensor, IR proximity sensor, Inductive Proximity Sensor and servo motor. The test results are that the lid will automatically open because it is driven by a servo motor if the ultrasonic sensor detects the presence of a maximum human within 72 cm. If the metal and non-metal trash bins are full the lid will not open and the buzzer will sound. Furthermore, when inserting trash, if the inductive proximity sensor and capacitive proximity sensor is worth 1 then what is detected is metal trash and the servo will rotate and direct the trash to the metal bin. Likewise, if only the capacitive proximity sensor has a value of 1 and the inductive proximity sensor detects a metal value of 0, the servo will rotate and direct the garbage to the non-metal trash can.

Abstract

Monitoring pH air sangat penting dilakukan untuk mengetahui baik buruknya kualitas air. Penyediaan air bersih dengan kualitas yang buruk dapat mengakibatkan dampak yang buruk bagi kesehatan masyarakat yaitu timbulnya berbagai penyakit. Perubahan pH air juga dapat menyebabkan berubahnya bau, rasa dan warna pada air. Sehingga pada penelitian ini dikembangkan sistem informasi secara terkomputerisasi berbasis Web dalam monitoring pH air yang diproduksi pada Balai Besar Industri Hasil Perkebunan (BBIHP) dilengkapi dengan Mikrokontroller WeMosD1, Sensor pH dan module sensor pH E-201-C. Berdasarkan hasil pengujian sistem monitoring ini dengan parameter kualitas air PDAM, air tanah dan air laut sebelum di desalinasi di peroleh nilai pH berkisar 6 sampai 8, sedangkan untuk air sesudah di desalinasi di dapat nilai pH berkisar 7. Paramater uji air ini sesuai dengan standar persyaratan kualitas air bersih berdasarkan Peraturan Menteri Kesehatan Nomor : 416/MEN.KES/PER/VII/2002 tentang persyaratan kualitas air bersih yang mensyaratkan nilai maksimum pH sebesar 6,5 - 9,0. Maka dapat disimpulkan bahwa sistem monitoring pH air berbasis Web pada pengukuran ini memenuhi syarat kadar pH yang diperbolehkan.
