Abstract

A braking system in a vehicle has a very important role in maintaining the safety of drivers and passengers, and preventing accidents. The brake system functions to reduce speed (slow down) and stop the vehicle. A good braking system provides safety and comfort for the drivers. Therefore, it is necessary to design the right braking system for “Sakera” car. In this study, an analysis and calculation of the braking system was carried out to determine the required braking force at a speed of 50 km/hour and other speeds in a distance of 15 m. The data taken in this study was the specification of the braking system used in the Sakera car. The braking system analysis was carried out on flat roads with varying speeds, namely 30 km/h, 35 km/h, 40 km/h, 45 km/h, and 50 km/h with a distance of 15 m for braking. The conclusions of the analysis were obtained, namely the greater the speed of Sakera's car, the greater the braking force to stop the car, the hydraulic pressure on the hose, and the force of the driver's feet, as well as the braking force needed on road conditions with a slope angle of 20º, which is 839.362 N.

Abstract

The world's rapid population growth, technological progress, and industrialization lead to an increase in fossil energy demand such as oil, coal, and natural gas. It is feared that this could lead to a scarcity of fossil energy in the future, therefore the use of alternative energy must be considered. One interesting concept to develop is waste to energy by utilizing plastic waste and also tires on vehicles. This is very possible because the two wastes contain elements of hydrocarbons which are also contained in fossil fuels so they can be processed to become alternative energy which can simultaneously reduce the population of the waste due to the increase in the world's population. This study aims to investigate the thermal behavior of scrap tires (ST) and polypropylene (PP) plastic using thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC). TGA thermogram showed that the feedstock samples were degraded in the temperature range of 331,97 oC to 448,08 oC. The interpretation of the DSC thermogram that showing information about the glass transition point and the melting point of the feedstock polymer will also be presented in this study.

Abstract

Penggunaan bahan bakar fosil pada Internal Combustion Engine memberikan dampak yang sangat serius terhadap lingkungan. Strategi dalam meminimalisir dampak tersebut adalah dengan pengaplikasian catalytic converter (CC) untuk mereduksi gas buang tersebut. Studi ini menggunakan metode sistematik review meta-sintesis, yaitu metode tinjauan sistematis kualitatif yang bertujuan untuk mengumpulkan dan mengekstrak informasi dari artikel yang dianalisis. Data dalam penelitian ini meliputi 22 artikel jurnal internasional terindeks Scopus peringkat Q4-Q1, conference prosiding serta book chapter terkait desain substrat dan material CC terhadap efektivitas reduksi gas buangnya. Hasil ulasan dibahas secara mendalam sehingga diperoleh insight bahwasanya desain substrat dan material CC memberikan dampak yang variatif terhadap efektivitas reduksi gas buang Internal Combustion Engine.

Abstract

Sistem pengapian motor, atau busi memegang peranan penting. Busi berfungsi untuk memercikkan bunga api yang diperlukan untuk membakar campuran bahan bakar dengan udara yang telah dikompresi. Tujuan dari penelitian ini adalah mengetahui perbandingan torsi, daya, dan KBBS pada motor bensin 4 langkah yang dihasilkan dari busi standar, kaki dua, platinum dan iridium. Pengujian ini menggunakan motor Yamaha Jupiter z. Pengujian unjuk kerja motor dilakukan dengan menggunakan dynotest (dynotest V3.3). Pengujian dilakukan secara bergantian untuk masing-masing busi dengan variasi putaran mesin 4000-10000 RPM dengan kenaikan 250 RPM pada gigi transmisi 3 digunakan untuk memperoleh perbandingan torsi (T), daya (P), konsumsi bahan bakar spesifik (KBBS). Peak torsi tertinggi didapatkan pada busi iridium mencapai 8,75 NM pada putaran 5069 RPM, daya tertinggi dihasilkan pada busi iridium dan busi kaki dua mencapai 8,1 Hp dan 8,1Hp pada putaran 7692 RPM dan 7892 RPM, KBBS terbaik didapatkan pada busi iridium mencapai 0,078 Kg/h.Hp pada putaran 6000 RPM.
