Abstract

This research aims to analyze O2 sensor troubleshooting on exhaust emissions and fuel consumption. The research method is comparative. Research steps by analyzing exhaust emissions and fuel consumption without an O2 sensor and with an O2 sensor at idle, 1000, 1500, and 2000 rpm. Research results: 1. comparison of exhaust emissions without O2 sensor and with O2 sensor, namely: idle rotation, CO = 7.41>3.33%, HC = 489 <497%, CO2 = 9.7 <12.5%, O2 = 13.44>0%, 1000 rpm, CO = 7.35>1.52%, HC = 686>538 ppm, CO2 = 9.7>11.8%, O2 = 10.91>2.20%, 1500 rpm, CO= 5.43>1.32%, HC= 666>472 ppm, CO2= 6.7>12.4%, O2= 13.25>4.95%, 2000 rpm, CO= 7.10>0.37%, HC= 499>272 ppm, CO2= 10.1<13.0%, O2= 11.24>9.03. 2. comparison of fuel consumption without o2 sensor and with o2 sensor, namely: idle rotation: 35=35ml, 1000 rpm: 15=15ml, 1500 rpm: 25>15ml, 2000 rpm: 15=15ml.

Abstract

President of the Republic of Indonesia, Joko Widodo, emphasized that currently the focus of education is to provide job skills to the younger generation. Vocational education and training will continue to be strengthened in line with the shift in development strategies from physical infrastructure development to human development. The closer the student is in working life, the better and professional educational goals are achieved. The purpose of this study is to create a 5-speed manual transmission learning media that can be used for learning. There are media test and tool use test with implementation power test and user response. The results of the test showed that media trials and tool use trials resulted in 75% feasibility. Eligibility is taken by filling the expert judgment which is more than 51%. Keywords: Learning Media, 5-speed Manual transmission, feasibility test

Abstract

The research aims to determine the effect of different spark plug variations on fuel consumption. The method used is a descriptive method. The tools and materials used are: copper spark plugs, platinum spark plugs, iridium spark plugs, 5 liter measuring cup, and pertalite. Fuel consumption analysis compared copper, platinum and iridium spark plugs with rpm 700, 1000, 1500, and 2000. Test results: 1) Fuel consumption for copper spark plugs with rpm 700, 1000, 1500, and 2000, namely 40ml, 10ml, 15ml and 10ml. 2) Fuel consumption for platinum spark plugs with rpm 700, 1000, 1500 and 2000, namely 20ml, 5ml, 25ml and 20ml. 3) Fuel consumption for iridium spark plugs with rpm 700, 1000, 1500 and 2000 is 50ml, 10ml, 10ml and 10ml. So platinum spark plugs are more fuel efficient than copper and iridium spark plugs.

Abstract

The design and implementation of keyless entry and starter rfid on Daihatsu Xenia Type Xi Year 2010 aims to: 1) Know the tools and materials used in the design and implementation of keyless entry and starter rfid on Daihatsu Xenia type Xi year 2010; 2) Understand the steps of the design and implementation of keyless entry and starter rfid on Daihatsu Xenia type Xi year 2010; 3) Be able to find out the results of testing the design and implementation of keyless entry and starter rfid on Daihatsu Xenia type Xi year 2010. The research method used is research and development. The steps of making the design include: The process of assembling an Arduino Uno-based rfid system, the process of inputting rfid tag data to the Arduino Uno, the process of assembling the keyless entry module cable to the car's electrical system, combining the keyless entry module with the Arduino Uno-based rfid system, placing the keyless entry module and the rfid system, finishing. Design and implementation of keyless entry and starter rfid on the 2010 Daihatsu Xenia Type Xi as a security feature on the 2010 Daihatsu Xenia Type Xi car. Based on the test results, it can be concluded that the design and implementation of keyless entry and starter rfid can work well, according to the following: increasing security, increasing comfort, increasing prestige, facilitating access, damage to the electrical system, not easily duplicated, still vulnerable to theft, easy battery drop, susceptible to electromagnetic signal interference.

Abstract

Kelompok Wanita Tani (KWT) Desa Jlegiwinangun menjual berbagai produk makanan dan minuman dari hasil pertanian. Namun pemasaran produknya masih belum maksimal, sehingga KWT menjadikan pekerjaan tersebut sebagai pekerjaan sampingan. Pengabdian ini bertujuan untuk menganalisis implementasi digital marketing dan branding produk usaha di KWTsebagai upaya pemberdayaan perempuan di bidang ekonomi. Metode yang digunakan adalah pendekatan kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa implementasi digital marketing melalui pelatihan penggunaan media sosial dan marketplace berhasil meningkatkan visibilitas dan penjualan produk KWT. Selain itu, branding produk dengan pembuatan logo, kemasan menarik, dan sertifikasi halal turut meningkatkan nilai jual dan kepercayaan konsumen. Dampak dari program ini adalah peningkatan pendapatan anggota KWT sebesar 15% dan perluasan jangkauan pasar hingga ke kota-kota besar. Pemberdayaan perempuan melalui peningkatan keterampilan digital dan kemandirian ekonomi juga berdampak positif pada peran mereka dalam keluarga dan masyarakat.
