Abstract

Abstract The use of LPG fuel in spark ignition engines continues to be developed, including the use of converter kits as a conversion tool from gasoline to LPG. However, the use of converter kits is not optimal because the mixture of air and gas has not been mixed heterogeneously in the combustion chamber. Therefore, it is necessary to redesign the converter kits that speed up the mixing process between air and gas. This study aims to evaluate the use of LPG fuel in spark ignition engines with converter kits on variations in throttle valve openings on exhaust gas emissions and exhaust gas temperatures. The research method used is an experiment with variations in the throttle valve opening on the engine are 25%, 50%, 75%, and 100%. Data that will be compared on the use of gasoline and LPG fuels include carbon monoxide (CO), hydrocarbon (HC), and mean gas temperature. The results showed that the use of fuel between gasoline and LPG on exhaust gas emission levels in spark ignition engines with variations in throttle valve openings was able to reduce CO emissions by 92% on average, HC by 72%, and increase the mean average temperature by 17%. This shows that the use of converter kits at each valve opening is able to reduce levels of CO and HC exhaust emissions compared to gasoline. However, it is inversely proportional to the mean gas temperature, at each variation of the gas valve opening there is a significant increase in temperature. This is because the heating value of LPG is greater than that of gasoline.Keywords—Exhaust gas emission, spark ignition engine, throttle valve open

Abstract

The development of technology in the automotive sector, especially motorcycles is increasing. This is indicated by the use of Electronic Fuel Injection (EFI) technology for the inclusion of the fuel system. Therefore, motorcycle repair shops must continue to upgrade their mechanical skills and expertise to meet customer needs in vehicle servicing. Kiki Motor Workshop is a motorcycle repair shop that is engaged in the service and replacement of motorcycle spare parts on micro exhibits. Judging from the service activities in the workshop, the average category of motorcycle being serviced is conventional technology (carburetor). Efforts are needed to improve the quality of human resources so that the workshop is able to receive motorcycle service services with EFI technology. The application of injector cleaner technology is a community service program that aims to improve the quality of services at the Kiki Motor workshop. In addition to improving the quality of the workshop, this program is expected to increase the income of the workshop.

Abstract

Karakteristik motor induksi ialah kecepatan putar yang merupakan fungsi dari frekuensi sumber listrik dan slip motor. Secara umum, jumlah catu daya listrik selalu konstan dan slip motor berubah sebagai akibat dari perubahan daya dan torsi, sehingga laju motor induksi harus dikontrol. Permasalahan tersebut membuat respon tidak stabil. Kontroler Fuzzy PI mempunyai sifat yang efektif pada saat system bersifat non-linear yang kompleks. Kontroler ini dirancang untuk mengupdate parameter-parameter logika fuzzy secara online sehingga output dari system lebih kokoh dari gangguan. Metode ini adalah pilihan yang sangat tepat dalam pengaturan kecepatan motor induksi dengan berubahnya beban terhadap waktu. Teknik pemodelan dalam penelitian ini adalah dengan mempertimbangkan state pada plant. Ini menempatkan persamaan menjadi linier sehingga diperoleh persamaan SISO. Metode Fuzzy PI mampu menurunkan nilai percent overshoot, setting time lebih baik dan aksi kontrol yang lebih smooth di bandingkan dengan metode yang lainnya.

Abstract

In the food processing industry, such as various types of crackers, various fried peanuts and various other packaged foods, the durability and durability of these food products must of course be given great attention. One of the reasons why various foods are not durable and expire quickly is the high oil content contained in these various foods. Manually draining oil is certainly not effective for the production of various foods in large quantities on an industrial scale. For that we need a tool or machine that can drain and reduce the oil content that is still contained in these various foods. The machine used is honey sweet potato chip spinner machine. Tawangmangu Village, Tawangmangu District, Central Java is known as a tourist area which is located on the slopes of Mount Lawu with various kinds of tourist beauty presented. Tourists often come to enjoy the natural beauty of Tawangmangu which is also rich in natural products, one of which is sweet potato honey. However, local residents cannot maximize honey sweet potato as a special food which is used as souvenirs for tourists, so there is a need for an effort to engineer food processing made from honey sweet potato in the form of procurement and training of electric powered honey sweet potato chip spinner machines for Karang Taruna Orpega 02 (Organization Erlangga Youth) in the Tawangmangu Village, Central Java. At the time of implementation, Mitra's enthusiasm was very large to take part in a series of training events for making food slicer spinners. There were 20 members of the youth group who took part in a series of training activities.
