Abstract

This research is a research and development (R&D) study utilizing the prototype development model. The aim of this study is to produce a development of an internet of things-based lighting control system. The functionality testing results achieved a 100% score, indicating that the prototype is suitable for use, and the user response results obtained a 100% score with the "Very Good" category. The testing results for the response time of the lamp for on/off commands showed a duration of 0-6 seconds, and the speed of feedback notifications from Telegram was 0-6 seconds. The testing for the speed of checking the lamp status ranged between 0-6 seconds. Meanwhile, for the LDR sensor trial, it successfully achieved 100% in sending notifications about the lamp's condition when a status check command is given.

Abstract

This research method is research and development which aims to produce and know the test results of the development of Arduino-based cigarette smoke detection devices at SMK Negeri 2 Makassar. This software system uses ISO 25010 using the system quality testing stage to obtain the results of functionality, usability, portability, Compatibility, Reliability, Security. This tool has been tested on 22 respondents. This tool has the potential to detect the presence of cigarette smoke or be used as a fire warning system. To improve the ability to detect cigarette smoke is to combine the Internet of Things (IoT) with the Arduino platform. The main components used in this system include Arduino, MQ7 sensor, Flame detector, NodeMCU ESP8266 module, Buzzer or speaker as audio alert, and electrical adapter. When smoke is detected past a predetermined threshold, this tool will issue a warning, both visual and audible, and send data through the Blynk application. In software reliability testing, we got 173 results from each coding and progress status is good or working which indicates the system has fulfilled the reliability aspect. For security testing using the OWSP ZAP application to determine vulnerability or security. As a result, the tool has a medium security level system, which states that the error rate on the server and coding (source code) in the application is categorized as safe

Abstract

Penelitian ini merupakan penelitian rancang bangun yang bertujuan untuk menghasilkan tempat sampah pintar mengunakan arduino uno. Penelitian ini adalah perancangan tempat sampah pintar menggunakan mikrokontroler. Pada penelitian ini, prosedur rancang bangun terdiri dari dua tahapan, yaitu perancangan perangkat keras dan perancangan perangkat lunak menggunakan bahasa C (terdiri dari pembuatan program utama dan pembuatan program controlling) dan diupload melalui arduino IDE. Teknik analisis data dalam penelitian ini adalah teknik analisis deskriptif. Hasil dari penelitian ini adalah sebuah prototype rancangan tempat sampah pintar yang memberikan pemberitahuan melalui aplikasi pada smartphone. Uji coba produk dilakukan dengan menguji komponen pendukung (sensor ultrasonik/jarak) dan menguji sistem secara keseluruhan. Hasil uji coba produk bahwa prototype ini berfungsi dengan baik yang diperlihatkan dengan kemampuan sistem memberikan pemberitahuan bahwa tempat sampah telah penuh melalui aplikasi.

Abstract

Penggunaan listrik adalah elemen yang sangat penting dalam kehidupan bermasyarakat, baik dalam rumah tangga, penerangan, komunikasi, industri dan sebagainya. Tenaga listrik merupakan salah satu faktor penting penunjang pembangunan, khususnya di bidang industri. Kehidupan modern menjadikan energi listrik sebagai elemen mutlak yang harus tersedia. Oleh karena itu, ketersediaan energi listrik harus terus terjamin. Upaya yang dapat dilakukan dengan pengendalian penggunaan energi listrik pada sisi hulu yaitu konsumsi (konsumen). Berdasarkan pertimbangan di atas, peneliti mengembangkan smart grid menggunakan sistem smart metering. Smart Power Meter ini bertujuan untuk menjadi sistem yang menggunakan teknologi IoT untuk memantau konsumsi daya dan mengontrol peralatan rumah secara real time. Penelitian ini merupakan penelitian dan pengembangan (R&D) yang bertujuan untuk mengembangkan prototipe jaringan sensor nirkabel untuk berkomunikasi dengan smart power meter dan menguji hasil prototipe jaringan sensor nirkabel untuk berkomunikasi dengan smart power meter. Penelitian ini menggunakan model pengembangan prototipe yang meliputi tahapan analisis kebutuhan, perancangan prototipe, pengembangan prototipe, dan pengujian prototipe. Data survei diperoleh melalui teknologi pengukuran dan kuesioner. Berdasarkan temuan tersebut, kami membuat prototipe jaringan sensor nirkabel untuk komunikasi smart power meter untuk memantau konsumsi daya listrik dan mengontrol perangkat listrik dengan smartphone berbasis Android. Hasil uji prototipe mencapai hasil yang sangat baik.

Abstract

This Uncontrolled and excessive use of water can lead to the scarcity of clean water supplies, considering that the world's fresh water supply is only about 3%. An example of uncontrolled water use is when a tap user forgets to close the tap so this causes water waste. Therefore, a tool is needed that can solve these problems. This research aims to develop an IoT-based system that is able to monitor water levels and detect the presence of a person in the bathroom automatically to reduce water waste and increase user comfort. The system utilizes HC-SR04 ultrasonic sensors to measure the water level in the bathtub and PIR sensors to detect motion as an indicator of the presence of people. The data from the sensors is processed by the ESP32 microcontroller and forwarded to the IoT Connect application, which allows users to monitor the water volume and presence in the bathroom in real-time. The system also features a solenoid valve that automatically opens and closes the water flow according to the data from the sensor, as well as an LED as a visual indicator. Test results show that the system is able to accurately monitor water levels and detect the presence of a person, as well as provide automatic control of water flow to prevent wastage. With the integration of the IoT Connect app, the system offers a practical and innovative solution for bathroom water management.
