Abstract

Pada penelitian ini telah dilakukan rancang bangun pengukur suhu kalorimeter menggunakan sensor DS18B20 berbasis Arduino Uno. Tujuan pada penelitian ini yaitu untuk merancang dan mengaplikasikan sistem pengukur suhu pada percobaan Kalorimeter. Pada proses rancang bangun terdapat dua tahapan yaitu perancangan hardware dan perancangan software. Perancangan hardware dibagi menjadi input terdiri dari Kalorimeter dan Sensor DS18B20, pemroses yaitu Arduino Uno, RTC dan Module SD Card, serta bagian output yaitu LCD. Perancangan software melakukan coding dan mengupload sketch pemrograman pada Arduino menggunakan software Arduino IDE. Metode pengujian pada penelitian terbagi dua yaitu kalibrasi sensor dan pengujian alat keseluruhan. Hasil kalibrasi yang diperoleh untuk penentuan kalor jenis menunjukkan nilai persentase kesalahan terendah yaitu 0,39% dan persentase kesalahan tertinggi yaitu 4,14%, dengan nilai rata-rata persentase kesalahan adalah 0,94%. Hasil pengujian alat keseluruhan pada penentuan kalor jenis nilai tertingi pada Sensor DS18B20 sebelum kalibrasi yaitu 44,38 oC dan sesudah pengolahan data menggunakan persamaan kalibrasi yaitu 44,85 oC dengan suhu referensi 44,8 oC. The design of a calorimeter temperature meter has been carried out using the DS18B20 sensor based on Arduino Uno. The purpose of this research is to design and apply a temperature measuring system in the calorimeter experiment. In the design process there are two stages, namely hardware design and software design. The hardware design is divided into inputs consisting of Calorimeters and DS18B20 Sensors, processors namely Arduino Uno, RTC and SD Card Modules, and output parts namely LCD. Software design does coding and uploads programming sketches on Arduino using the Arduino IDE software. The test method in this study is divided into two, namely sensor calibration and overall tool testing. The calibration results obtained for determining the specific heat showed the lowest percentage error value, namely 0,39% and the highest error percentage, namely 4,14%, with an average error percentage value of 0,94%. The overall test results for determining the highest specific heat value on the DS18B20 sensor before calibration were 44,38 oC and after data processing using the calibration equation, namely 44,85 oC with a reference temperature of 44,8 oC.

Abstract

The Android-based GCS (Ground Control System) has been designed to operate the wireless prototype tractor. This research aims to design the GCS system as a controller for the prototype tractor. The research method employed is the sequential linear method. The conducted tests include data transmission time testing from the application, GPS testing, and prototype response testing. The testing involves comparing the command data transmission time from the application with the time it arrives at Firebase. Based on the obtained data, it can be seen that the data transmission speed and reception have no gaps. This is due to a stable network connection, enabling real-time communication between the application and Firebase. GPS testing is conducted to assess the accuracy of coordinate readings for determining the prototype's position. The prototype's position can be determined using the obtained coordinates, namely latitude and longitude, which are read from the GPS module installed on the device. The test results indicate a difference between the prototype's coordinate point (reference coordinate) and the coordinate point obtained from the timestamp application. The difference in coordinate readings between the prototype and the average plotted result is 0.2 meters. Prototype response testing is carried out to evaluate the device's responsiveness to commands from the control system on the smartphone. This test involves sending motion direction commands that the device needs to follow, followed by measuring how quickly the device responds to those motion commands. Based on the obtained data, the time required for the device to respond to the forward command provided is 01.61 seconds and 01.88 seconds.
