Abstract

Telah dibuat sistem kontrol arus HHO generator menggunakan arduino dan menggunakan model linear quadratic regulator. HHO generator merupakan alat yang mengubah air menjadi gas hidrogen dan oksigen yang biasa digunakan untuk keperluan efisiensi mesin berbahan bakar minyak. Untuk menghasilkan gas hidrogen dan oksigen yang stabil, dibutuhkan sistem kontrol parameter arus. Kontrol terhadap arus dilakukan menggunakan arduino dengan sensor arus ACS712, sensor tegangan INA219, dan aktuator MOSFET IRF530n. Sedangkan pemodelan sistem ruang keadaan dan desain kontrol LQR menggunakan MATLAB. Dari hasil uji didapatkan model sistem yang observable, kontrolabel, dan stabil. Pada respon step sistem kontrol menunjukkan pengontrol memiliki kecenderungan yang kurang stabil.

Abstract

The use of control systems for industrial automation is currently achieving rapid movements, one of which is the Distributed Control System (DCS). DCS has several generations in terms of software and hardware. This research discusses DCS upgrades in terms of hardware. Upgrading DCS from Remote Input/Output (R I/O) to Network Input/Output (N I/O) has two stages, upgrade software and hardware upgrading run simultaneously. CS 3000 is still integrated with Windows 7, which is software from R I/O, while to keep up with the development of Windows technology, 10 R I/O cannot reach it. For N I/O itself, it uses Centum VP software that is integrated with Windows 10. R I/O is limited to using RJ45 cable, which has a range of tens of meters, so it must use a repeater to connect long-distance communication. While, in communication between Marshalling Cabinets with field instruments, fibre optics can reach 5 km, save costs, transfer data faster, and only need one connecting cable.

Abstract

Peranan gas LPG (Liquefied Petroleum Gas) pada saat ini sangatlah penting bagi bagi kehidupan manusia. Namun disaat yang bersamaan, dibalik penggunaan gas LPG yang semakin banyak, mulai muncul berbagai masalah. Gas LPG mempunyai dampak negatif terhadap manusia bahkan dapat menimbulkan potensi bahaya ledakan dan kebakaran. Maka perlu adanya sistem deteksi dan pengaman yang dapat mengatasi masalah yang timbul apabila terjadi kebocoran gas LPG. Pada makalah ini ini telah berhasil dirancang sistem deteksi dan pengaman kebocoran gas menggunakan sensor MQ-6 berbasis algoritma Bahasa C. Variasi pengujian dilakukan untuk mengetahui tingkat akurasi dan respon waktu sistem yang dibangun dalam mendeteksi kebocoran. Hasil pengujian menunjukkan bahwa sistem mampu mendeteksi kebocoran gas LPG dengan rentang persentase error sebesar 2.95%-6,09%. Selanjutnya sistem juga mampu mengamankan kebocoran gas LPG melalui aktivasi automatic shutoff valve pada regulator dalam rentang respon waktu sebesar 0.3-0,9 detik.

Abstract

The program to convert kerosene to LPG (Liquefied Petroleum Gas) launched by the government since 2007 has had a positive impact, among other things because energy consumption has become more economical and use is relatively cleaner and easier. However, this program has negative impacts, including the potential for explosion and fire hazards due to gas leaks in the cylinders. Factors that can cause leaks in LPG cylinders are improper installation of the regulator, poor quality cylinder sealing rings, and even regulators that do not have the Indonesian National Standard (SNI). Seeing the potential for great danger due to gas leaks in LPG cylinders, the solution that can be implemented is to build a safety shut off valve system on LPG cylinders. In this paper, a safety shut off valve system is described which is designed and placed in the tube regulator section. System test results with an LPG gas concentration of 5000 ppm (parts per million) show that the average response time of the system in automatically activating the safety shut off valve is 0.55 seconds. The accuracy value of the designed system is shown through comparison with the results of mathematical calculations, namely having an error in the range of 1.76 percent - 3.43 percent at a sensor reading distance of 0 - 100 cm.
