Abstract

Technological developments in Indonesia are relatively rapid, and most people have become part of the Internet of Things era. There are a couple of new technologies in the Internet of Things, one of which uses long-range (LoRa) communication technology, a wireless delivery method using radio signals at a frequency of 433 MHz. Meikarta Central Park is a city park that provides tourist bicycle rentals. Problems often occur when visitors rent bicycles, resulting in tourist bicycles being lost or placed incorrectly. All these problems make it difficult for operators to find abandoned bicycle locations. This research develops a system to detect the location of Meikarta’s tourist bicycles using a GPS tracker with an Arduino microcontroller based on a long-range working principle. On the other hand, the location point can be seen on the map’s application so that the whereabouts of the bicycle can be known. The research results of the tracking from the tourist bicycle GPS tracker using LoRa were 5 test locations, the furthest range of 625 meters on the first tourist bicycle with an accuracy value of 11.2 meters. Meanwhile, the second tourist bike has the most extended range of 590 meters with an accuracy level of 4.4 meters.

Abstract

Energy is an object that can move through essentialreactions; increasing population growth is one of the factors forincreasing energy needs. One of the initiatives initiated was thecreation of a Thermal Electric Generator (TEG). The formulationof the problem in this study is to determine the output voltage,current, and power generated by the thermoelectric as analternative energy and to determine the effect of temperature onthe thermoelectric. The goal is to determine the amount of outputthe thermoelectric generates when it gets a heat source from thedispenser. The data source in this study was obtained from testingthe tools made. The test results show the effect of temperature onthe thermoelectric tested for 120th minutes test of max 5.96 Voltswith a water temperature in the dispenser tank of 73C withoutusing a step up using six pieces of thermoelectric arranged inseries.

Abstract

Sistem peringatan keamanan lalu lintas pada pertigaan jalan telah dikembangkan pada penelitian ini. Sistem ini dirancang untuk mengganti penggunaan rambu dan alat bantu seperti cermin yang kurang efektif karena keterbatasan bidang pantulan dan gangguan akibat kondisi cuaca. Sensor PIR dan mikrokontroler ESP8266 digunakan untuk pemrosesan program pendeteksi kendaraan yang mendekati area pertigaan dengan pembagian skema menggunakan modul DOT MATRIC219. Penelitian ini memberikan beberapa skema pesan seperti ”STOP”, ”SLOW”, dan “HATI-HATI” dalam pemberian perintah disertakan isarat lampu merah, kuning dan hijau sebagai peringatan konvensional. Metode perancangan menggunakan basic pemrograman Arduino IDE. Dengan penerapan peringatan, pengendara dari berbagai arah diharapkan dapat meningkatkan kewaspadaan sehingga risiko kecelakaan di area pertigaan dapat dikurangi. Hasil penelitian menunjukkan sensor PIR dapat mendeteksi pergerakan ketika objek ditempatkan dengan jarak 50 cm sampai 325 cm dari sensor. Uji efektivitas sudut sensor PIR pada jarak 50 cm sampai 300 cm dengan sudut 0º sampai 60º sensor PIR dapat mendeteksi pergerakan. Logika sistem ESP8266 yang sudah diprogram berjalan dengan baik ketika menerima perintah maupun dalam keadaan standby. This study developed a traffic safety warning system for T-junctions. It replaces traditional signs and mirrors, which are often less effective due to limited reflection and adverse weather. Specifically, the system uses passive infrared (PIR) sensors and ESP8266 microcontrollers to detect vehicles, while the DOT MATRIC219 module handles message display. Warning messages like "STOP," "SLOW," and "CAUTION" are shown with red, yellow, and green lights. These alerts provide clear visual warnings. For system design, an approach with Arduino IDE programming was employed. The purpose of these warning signals is to improve driver vigilance from all directions and reduce accident risk at T-junctions. Experimental results show that the PIR sensor reliably detects movement at distances between 50 cm and 325 cm and is effective within an angle range of 0º to 60º from 50 cm to 300 cm. Finally, the programmed ESP8266 logic works correctly in both command and standby modes.
