Abstract

Indonesia's drought and water crisis problems have grown significantly in importance in recent years, especially in light of the country's fast population expansion, urbanization, and growing awareness of the effects of climate change. By 2040, there may be a clean water crisis in every region along Java's north coast, from Banten to Surabaya, according to projections made by the Indonesian Institute of Sciences (LIPI). The water crisis could be a major worldwide concern and will be a highly complicated issue. One approach to resolving the water shortage is to design an air-to-water converter device. The purpose of this research is to design a device that can efficiently and effectively convert air into water through condensation processes. The design will be based on the VDI 2221 Method. The rationale behind selecting the VDI 2221 Method is that it is a methodical approach to design that can help a designer generate and guide multiple design options. The primary mechanism of this apparatus is condensation, which turns air into dew points. The author utilized Solidworks 2020 to create the air-to-water conversion device. Through the stages of VDI 2221, the finest design outcomes were obtained from this design. The air-to-water converter mechanism in this design is constructed by version 2, which was chosen as the best option. Based on ASTM A36 material, theoretical calculations on the frame produced a safety factor of 1.45 and a maximum stress of 1.72414 × 108 N/m2. Based on the turbine shaft calculation, the maximum stress of 1.07235 × 108 N/m2 and the safety factor of 2.57379 were obtained using Aluminum 6061 material

Abstract

Motor bensin merupakan salah satu jenis motor pembakaran dalam yang digunakan untuk menggerakkan atau sebagai sumber tenaga dari suatu kendaraan. Optimalisasi pada proses sebelum pembakaran dapat meningkatkan performa mesin seperti melakukan pergantian pada komponen reed valve. Reed valve atau katup buluh bekerja berdasarkan kehisapan pada ruang engkol dan mekanisme yang tidak terhubung dengan putaran mesin. Penelitian ini dilakukan untuk mengetahui pengaruh reed valve standar dan dual stage reed valve terhadap torsi, horsepower, konsumsi bahan bakar pada sepeda motor Yamaha RXK 135 cc. Penelitian ini menggunakan metode eksperimental dimana pengujian dilakukan secara bergantian untuk masing-masing variasi reed valve untuk memperoleh torsi, horsepower, dan konsumsi bahan bakar menggunakan Pertalite. Pengujian dilakukan pada tingkat putaran mesin 6800-16000 rpm menggunakan mesin dynotest di Alonso Lee Motor Workshop. Hasil penelitian menyimpulkan bahwa torsi dan daya tertinggi didapatkan oleh lidah membran standar dengan nilai 18,91 HP pada 9500 rpm dan 14,7 N.m pada 8450 rpm sedangkan pada lidah membran dual stage menghasilkan torsi dan daya sebesar 18,38 HP pada 14500 rpm dan 9,49 N.m pada 12540 rpm. Hal tersebut dikarenakan bahan dari lidah membran dual stage yang lebih kaku. Sehingga membuat penghisapan bahan bakar kurang responsif dibandingkan dengan lidah membran standar yang berbahan lebih lentur sehingga mampu melakukan penghisapan bahan bakar lebih cepat dan mengoptimasi kinerja mesin. Kata kunci : katup buluh; membran; mesin dua langkah; yamaha RX king.
