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.

Abstract

Perkembangan teknologi yang semakin maju sehingga penggunaan cara konvensional sudah tidak efesien lagi. Saat ini dibutuhkan alat yang dapat memudahkan manusia dalam melakukan pekerjaan seperti dalam proses pengemasan udang di industri masih menggunakan cara manual yaitu mengambil udang kemudian dimasukkan kedalam plastik kemasan lalu ditimbang sesuai dengan permintaan dari konsumen. Pembuatan model alat pengemasan otomatis berawal dari industri yang masih menggunakan penghitungan dan pengemasan dan penimbangan secara konvensional. Tujuan penelitian ini membuat sistem pengemasan udang otomatis berdasarkan berat menggunakan konveyor, pada penelitian ini digunakan konveyor sebagai alat penggerak box dan udang Setelah melakukan perancangan dan pengujian dan analisa alat dapat disimpulkan yaitu dari pengujian alat pengemasan udang berdasarkan berat ini sensor load cell sebagai sensor berat berfungsi dengan baik dengan data percobaan menggunakan berat 100 gram memiliki akuratan 90% sedangkan dengan data percobaan menggunakan berat 50 gr memiliki ke akuratan 100% Dalammendeteksi berat udang dalam box pengemasa, dengan menggunakan kecepatan 255 rpm motor dc konveyor serta proximity sebagai sensor kedatangan box pengemasan bekerja dengan baik sesuai program yang telah dibuat.

Abstract

Lack of understanding regarding electrical power usage is a common problem that often occurs. Consumers only know the amount of electricity used when they receive their monthly bill, which often causes confusion or dissatisfaction with the bill value which is considered unreasonable or too high. The aim of this research is to monitor electrical energy usage in real time and be able to display the costs of electrical energy usage. This protection system is designed using the PZEM-004t current sensor and ESP-32 microcontroller package. The reading of electrical quantities (voltage, current, active power, energy) carried out by the PZEM-004t sensor is then sent to the microcontroller, on the microcontroller the value of the electrical quantity is converted into rupiah prices and displayed on the LCD display. Monitoring via smartphone is made using a simple application creation platform, namely MIT App Inventor, connected to the internet network with a microcontroller so that electrical energy use can be monitored via smartphone. The test results show that the tool that has been created is capable of displaying the cost of electrical energy usage in accordance with the electricity tariff calculation of 900 Watts. and has a voltage measurement accuracy level of 99.4% and a current measurement accuracy level of 92.1%. If an overcurrent or short circuit occurs, the relay will disconnect the load from the PLN source. This condition will remain Off until the load returns to normal. If the load is reduced until the current is below the nominal current value of the current sensor that has been set, the relay will reconnect and the system will return to normal. In abnormal circuit conditions, before the relay breaks the circuit, the buzzer will sound.
