Penelitian ini bertujuan untuk merancang dan membuat interface komunikasi data antara Electronic Control Unit (ECU) sepeda motor dengan sistem Android. Masalah yang dihadapi oleh bengkel rumahan seperti Ngoprek Garage Motoshop adalah keterbatasan alat untuk mendeteksi kerusakan ECU secara otomatis. Penelitian ini menggunakan mikrokontroler ESP32 sebagai penghubung antara ECU dan aplikasi Android, yang dirancang menggunakan MIT App Inventor. Sistem ini mampu membaca data kesalahan (Diagnostic Trouble Code/DTC) dari ECU dan menampilkannya secara langsung pada aplikasi Android. Metode penelitian yang digunakan mencakup perancangan perangkat keras dan perangkat lunak, serta pengujian sistem terhadap sepeda motor Honda. Hasil menunjukkan bahwa sistem ini mampu membaca dan menampilkan kode DTC dengan akurasi yang cukup tinggi, meskipun terdapat keterbatasan pada pembacaan parameter data secara real-time. Sistem ini diharapkan menjadi solusi alternatif bagi bengkel kecil dalam melakukan diagnosa awal terhadap kerusakan ECU.

Electric Vehicles Require A Reliable Monitoring System To Maintain Their Efficiency And Safety.

The System Uses The Pzem 017 Sensor To Monitor Voltage, Current, Power, Energy, As Well As Battery Capacity And Health, And The Neo-7m Gps Module For Location Tracking. Data Is Displayed In Real Time Through An Android Application. Test Results Show That The System Provides Accurate Information, With Minimal And Statistically Insignificant Measurement Errors According To The Paired T-Test. The System Also Remains Stable At Various Vehicle Speeds (Anova), And The Location Tracking Demonstrates An Average Accuracy Of 4.77 Meters In Open Areas. In Enclosed Areas, The Error Increases To An Average Of 10.26 Meters. The System Is Also Capable Of Automatically Calculating Battery Capacity And Health. Overall, The Developed System Proves To Be Effective, Efficient, And Flexible In Supporting The Reliability And Safety Of Electric Vehicles.

The phenomenon that occurs in the load lifting system is the need for an efficient and reliable mechanism to move the crane hoist pulley vertically and horizontally. This study aims to design and test a crane hoist system that uses a DC motor and a stepper motor controlled by an L293D motor driver, and to develop an application based on MIT App Inventor to control the movement of the motor. The research method used is integrated hardware and software design, followed by testing the performance of the motor, driver, and the application developed. Testing was carried out under limited load conditions, to measure the motor speed, voltage, and current used at loads of 10 to 100 grams. The results of the study showed that the system can function well at varying speeds, and the motor is able to lift a maximum load of up to 100 grams with a speed that decreases according to the weight of the load. The MIT App Inventor application successfully controls the motor effectively via a WiFi connection with a maximum distance of 10 meters, and loads the operation of the crane vertically and horizontally. This study proves that the designed system is able to work optimally in lifting and moving loads, and the application developed provides easy and efficient control.

Stroke is a physical disability disease, which affects the upper extremity motor system. To support post-stroke motor rehabilitation, research on IoT-based elbow exoskeleton therapy devices that help elbow therapy with flexion and extension movements. The therapy device uses DS-SERVORD5160 as the main driver to provide flexible movement. By using the ESP32 microcontroller control system equipped with a Bluetooth connection that is connected via the MIT App Inventor application from a smartphone that can be done at home to increase the effectiveness of post-stroke recovery. The results of this study with low (20°), medium (40 °) and high (60 °) modes by providing a maximum load of 2 Kg. It can be concluded that the device shows stable performance in low (20 °) and medium (40 °) modes, but in testing with high mode (60 °) with a load of 2 Kg there is a decrease in servo performance which is indicated by the instability of the servo movement which shows an angle of 56 °.

In the era of globalization, technology increases efficiency in various human activities, including plant cultivation. Chili plants require special care, especially in meeting water needs according to ideal soil moisture, which is 30% -50% for chili. Conventional monitoring methods are inefficient because they require a lot of time and energy. A new breakthrough is needed to continuously monitor temperature, air humidity, and soil moisture. The designed tool will be placed in Cipadung Village to monitor soil moisture in chili plants, which require soil moisture that is not too high. This tool facilitates monitoring through the application, allowing automatic and manual watering. Soil moisture stability is also important for tomatoes, so watering can be regulated through the application display. This tool is useful for monitoring soil moisture levels effectively, supporting plant care with stable soil moisture needs, and facilitating the watering process through the application.

This research aims to create or design an interactive physics learning media application using MIT App Inventor on GLB and GLBB topics. This research applies the MDLC (Multimedia Development Life Circle) method by Luther-Sutopo in the application creation process. The following stages in MDLC are concept, design, material collecting, assembly, testing, and distribution. The Android application created was tested using two stages in MDLC, namely the alpha validator and beta validator, where the alpha validator consisted of material experts and media experts. In contrast, the beta validator comprised 14 students majoring in first-semester physics education. The analytical approach used is a qualitative method and a quantitative method to assess how appropriate the learning media created is. The research shows the results, namely a) Creation of interactive physics learning media based on Android applications using MIT App Inventor on GLB and GLBB topics, b) The level of feasibility of interactive physics learning applications based on Android applications based on media experts, namely 91% or very feasible, and based on material experts. Namely 90.6% or very feasible, and c) Based on the implementation and results of trials with students, the level of feasibility of the Android-based physics interactive learning application is 84.46% or worthy of being an alternative reference source for physics learning on GLB and GLBB topics.
