Abstract

Hole injector memiliki peran terhadap campuran bahan bakar di ruang bakar. Penelitian ini bertujuan untuk mengetahui penggunaan hole injector variasi terhadap konsumsi bahan bakar, top speed, dan emisi gas buang pada sepeda motor type matic. Metode eksperimen dilakukan dengan membandingkan penggunaan hole injector standar (6 lubang) dan hole injector variasi (8 lubang). Data penelitian secara langsung diambil dari kinerja sepeda motor Honda Beat Street kemudian disajikan dengan metode deskriptif persentase. Hasil penelitian berupa konsumsi bahan bakar, top speed, dan emisi gas buang berhasil diperoleh dan dianalisa lebih lanjut. Dari analisa dapat disimpulkan bahwa injector variasi 8 lubang memiliki hasil yang tidak baik karena konsumsi bahan bakar menjadi boros dan peningkatan emisi gas buang. Sehingga penggunaan injector ini tidak direkomendasikan untuk digunakan pada sepeda motor matic. Hole injectors have a role in the fuel mixture in the combustion chamber. This study aims to determine the usage of hole injector variations on fuel consumption, top speed, and exhaust emissions on matic type motorbikes. The experimental method was carried out by comparing the use of standard hole injectors (6 holes) and hole injector variations (8 holes). Research data was directly taken from the performance of Honda Beat Street motorbike and then presented with descriptive percentage method. The research results in the form of fuel consumption, top speed, and exhaust emissions were successfully obtained and further analyzed. From the analyses it can be concluded that the 8-hole variation injector has poor results due to wasteful fuel consumption and increased exhaust emissions. So the use of this injector is not recommended for use on matic motorbikes.

Abstract

Buck converter merupakan salah satu jenis konverter DC-DC yang sangat berguna dalam mengubah tegangan DC tinggi menjadi tegangan DC yang lebih rendah. Hal ini menjadi kritis dalam sistem elektronika modern yang memerlukan tegangan yang lebih rendah untuk berbagai komponen seperti mikrokontroler, sensor, dan perangkat lainnya. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem kendali tegangan keluaran pada buck converter dengan menggunakan metode fuzzy logic dan GUI MATLAB. Dengan adanya penggunaan metode fuzzy logic, buck converter dapat beradaptasi dengan baik terhadap perubahan beban dan fluktuasi sumber tegangan masukan, sehingga menghasilkan tegangan keluaran yang lebih responsif dan stabil. Kemudian, dengan kehadiran GUI MATLAB, hal ini akan mempermudah pengguna dalam melakukan pengontrolan sistem atau aplikasi dengan cara yang lebih efisien dan mengontrol tegangan keluaran buck converter sesuai dengan kebutuhan aplikasi yang beragam. The buck converter is one type of DC-DC converter that is highly useful in transforming high DC voltage into lower DC voltage. This is crucial in modern electronic systems that require lower voltage for various components such as microcontrollers, sensors, and other devices. This research aims to design and implement an output voltage control system for the buck converter using fuzzy logic methods and a MATLAB GUI. By employing the fuzzy logic method, the buck converter can adapt well to load variations and input voltage source fluctuations, resulting in a more responsive and stable output voltage. Additionally, with the presence of the MATLAB GUI, this will facilitate users in efficiently controlling the system or application, allowing them to control the output voltage of the buck converter according to diverse application requirements.

Abstract

Tulisan ini membahas perancangan perangkat keras emulator sel surya, memonitoring keluaran emulator menggunakan MATLAB GUI, dan membandingkan karakteristik hasil pengukuran langsung dengan karakteristik hasil simulasi untuk mengetahui unjuk kerja sistem panel surya. Emulator panel surya ini akan dimodelkan dengan persamaan matematis di Arduino Uno dengan menginputkan nilai iradiasi, suhu, arus dan tegangan keluaran buck converter yang diberikan sebagai umpan balik dan menghasilkan arus referensi yang kemudian dibandingkan dengan arus keluaran buck converter dimana kesalahan perbandingan akan di kontrol oleh kendali PID. Hasil uji coba dengan hardware emulator sel surya menunjukkan karakteristik yang mirip dengan modul Solkar 36, dengan tingkat kesalahan rerata sekitar 5,16% untuk daya maksimum, 2,08% untuk arus short circuit, dan 0,28% untuk tegangan open circuit. Penurunan nilai iradiasi mengakibatkan penurunan rata-rata pada arus short circuit, tegangan open circuit, dan daya maksimum sekitar 0,761 A, 0,558 V, dan 17,034 W. Selain itu, rata-rata penurunan Voc dan daya maksimum akibat kenaikan suhu 10 ºC yaitu 0,26 V dan 1,11182 W, sedangkan Isc mengalami peningkatan sekitar 0,015 A. This study discusses the hardware design of a solar cell emulator, monitoring the emulator's output using a MATLAB GUI, and comparing the characteristics of direct measurements with the characteristics of simulation results to determine the solar panel system's performance. This solar panel emulator will be modeled with mathematical equations on an Arduino Uno by inputting values such as irradiance, temperature, current, and output voltage of the buck converter as feedback and generating a reference current, which is then compared with the buck converter's output current. The comparison error will be controlled by a PID controller. Experimental results with the solar cell emulator hardware show characteristics similar to the Solkar 36 module, with an average error rate of about 5.16% for maximum power, 2.08% for short-circuit current, and 0.28% for open-circuit voltage. A decrease in irradiance results in an average decrease in short-circuit current, open-circuit voltage, and maximum power by about 0.761 A, 0.558 V, and 17.034 W, respectively. In addition, the average decrease in Voc and maximum power due to a 10 ºC temperature increase is 0.26 V and 1.11182 W, while Isc increases by approximately 0.015 A.
