Abstract

The online student registration system at the Al-Qaaf Foundation is an effective solution to overcome registration problems that are usually done manually. Based on research and testing, 90.25% of respondents stated that this application is very suitable to help users in managing enrollment data in schools. This shows that the majority of respondents feel that this system is useful and able to meet their needs. However, 9.75% of respondents indicated that the app still needs further development, indicating that there are some shortcomings or features that need to be improved or added. Input from respondents who feel the need for development can be the basis for making improvements and improvements to the system. Overall, the use of the registration system at the Al-Qaaf Foundation can provide benefits in the management of student registration data. However, it is important to continue to evaluate, develop, and improve the system so that it can continue to meet user needs and contribute optimally in the field of education.

Abstract

ABSTRAK Polusi udara akibat dari peningkatan penggunaan jumlah kendaraan bermotor yang mengeluarkan gas-gas berbahaya akan sangat mendukung terjadinya pencemaran udara dan salah satu akibatnya adalah adanya pemanasan global. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penggunaan BRQ dan Eco Racing terhadap performa mesin dan emisi gas buang pada kendaraan tipe mesin 4 langkah yang menggunakan bahan bakar pertalite dan pertamax, serta untuk mengetahui efektifitas produk dalam meningkatkan performa mesin dan emisi gas buang. Hasil penelitian menunjukkan bahwa penggunaan BRQ dan Eco Racing berdampak pada performa mesin sepeda motor 4 langkah 110 cc. Peningkatan performa mesin dan emisi gas buang terjadi pada uji BRQ dan Eco Racing. Penggunaan BRQ lebih efektif dalam meningkatkan performa mesin jika dibandingkan dengan Eco Racing. Tetapi terjadi detonasi dan knocking pada penggunaan pertamax rendaman BRQ. Penggunaan pertalite campuran BRQ lebih menghemat biaya bahan bakar kendaraan. Disarankan untuk penelitian selanjutnya dapat menguji efek jangka panjang dari penggunaan kedua produk BRQ dan Eco Racing dan mencari cara untuk mengatasi efek detonasi dan knocking pada penggunaan bahan bakar pertamax rendaman BRQ. Kata kunci: brq, eco racing, performa mesin sepeda motor, emisi gas buang sepeda motor. ABSTRACT Analysis of the use of catalysts and fuel additives on performance and exhaust emissions on the Honda Beat esp. Air pollution as a result of the increasing use of the number of motorized vehicles that emit harmful gases will greatly support the occurrence of air pollution and one of the consequences is global warming. The purpose of this study was to determine the effect of using BRQ and Eco Racing on engine performance and exhaust emissions in 4 stroke engine type vehicles that use pertalite and Pertamax fuel, as well as to determine the effectiveness of the product in improving engine performance and exhaust emissions. The results showed that the use of BRQ and Eco Racing had an impact on the engine performance of a 110 cc 4 stroke motorcycle. Improved engine performance and exhaust emissions occurred in the BRQ and Eco Racing tests. The use of BRQ is more effective in improving engine performance when compared to Eco Racing. However, detonation and knocking occurred when using pertamax BRQ immersion. The use of BRQ mixed pertalite saves more on vehicle fuel costs. It is recommended for further research to examine the long-term effects of using both BRQ and Eco Racing products and find ways to overcome the effects of detonation and knocking on the use of Pertamax BRQ immersion fuel. Keywords: brq, eco racing, motorcycle engine performance, motorcycle exhaust emissions.
