Abstract

Faktor penyebab kecelakaan disebabkan karena factor pengemudi dan kendaraan. Hal ini terjadi karena pengamudi kurang memperhatikan kecepatan, tata cara pemuatan, serta beban yang dibawa. Kecepatan serta beban muatan yang berlebih bisa mengakibatkan rem blong. Tata cara pemuatan yang salah juga mempengaruhi kinerja sistem pengereman. Pengujian efisiensi rem yang dilakukan secara statis belum bisa menjamin bahwa kendaraan tersebut dalam kondisi baik. Pada penelitian ini dilakukan dengan pengujian rem road test dengan penambahan beban, kecepatan, dan tata cara pemuatan untuk mengetahui jarak pengereman. Hasil dari penelitian ini menunjukkan bahwa penambahan beban muatan, perubahan kecepatan, dan perubahan tata cara muat dapat mempengaruhi jarak pengereman. Dari perhitungan perlambatan yang telah dilakukan dapat disimpulkan bahwa nilai perlambatan dipengaruhi oleh jarak pengereman, penambahan beban muatan, perubahan kecepatan, dan perubahan tata cara muat dapat mempengaruhi nilai perlambatan.

Abstract

In Indonesia, the Application-Based Taxis (ABT) operators argue that they are not required to undergo periodic testing, unlike in other countries. This research aims to address this issue by conducting a qualitative study using three approaches: regulatory review, comparison of policies from other countries, and in-depth interviews with ABT company officials and 100 drivers. The study found that 41% of drivers refused to follow the regulation, citing financial burdens. The study proposes that ABT vehicles undergo periodical testing for four years, repeated annually, similar to other countries. Random inspections of ABT vehicles on the road are also recommended to increase awareness of vehicle maintenance, with a focus on tire and brake condition. This study aims to improve the roadworthiness of ABT vehicles in Indonesia.

Abstract

An increase in the volume of waste if it is not accompanied by good management, will certainly have a bad impact on reducing the quality of the environment. In Jempong Baru village which has a population of 17,172 people, but currently only has 1 TPS located in the east Jempong neighborhood which has an area of 36 m3 with a capacity of 72 m3 and 1 damtruck with a capacity of 7 m3, which should be insufficient facilities, but in fact there is no garbage overflowing out of the TPS. For this reason, it is necessary to further study the current real condition (existing position) compared to the condition if all villages dispose of waste at the TPS in the environment of the research site (alternative position), in terms of the size of the volume of waste and the number of minimal waste facilities needed. The result of this study is that a dumptruck with a capacity of 7 m3 is able to transport waste from the TPS to the landfill, which is as much as 3 times / day (3 irritations). The total amount of waste generated in Jempong Baru Village in the existing position is 28.97 m3 / day and in the alternative position of 121.47 m3 / day. In the existing position, 1 TPS with a capacity of 72 m3 and 1 dumptruck with a capacity of 21m3 / day are sufficient. Meanwhile, in the alternative position, the facilities needed to handle the volume of waste as much as 121.47 m3 / day are at least 1 TPS and 6 dumptrucks

Abstract

Currently, the vehicles that are commonly used are vehicles with fossil fuels, but we all know that these fuels are non-renewable fuels and their availability in nature is very limited, so it is necessary to innovate to use other renewable energy sources. one of which is electrical energy. Besides that, the use of electrical energy for vehicles is currently very relevant because of its relatively high efficiency and friendly to the environment, namely no CO or CO2 gas is formed as in conventional vehicles. Indonesia has the potential to develop electric cars because there is a lot of nickel available to be processed into batteries. Thus, our country has a very large opportunity to produce electric cars. To realize this, it is deemed necessary to conduct a thorough study such as the level of comfort and safety. Thus, it is needed to conduct a study of the mechanical control system so that driving comfort and safety can be achieved. In this research, we will measure the turning radius of the vehicle at various TOE angles. The resulth of this study are the greater of TOE angle produce the higer the turning radius of the vehicle, The smallest turning radius is at a TOE angle 0 degrees which is 4.42 meters and the largest at a TOE angle 1.035 degrees which is 4.53 meters.

Abstract

Every three accidents occur every hour in Indonesia, according to the Director of Road Traffic at the Ministry of Land Transportation, with a percentage of over 50-70 percent and 30 percent of accidents occur due to poor performance of the brake system. Accidents occur due to insufficient braking distance and lack of understanding of the braking characteristics of the vehicle being driven. The aim of this research is to analyze the distance, time and braking force required for an electric car to move until it stops with variations in speed and vehicle load. This research was carried out using an experimental method where a prototype electric car was run by varying the speed and load of the vehicle to obtain braking time and distance and analyzing the data obtained. The shortest braking distance at a speed of 20 km/hour with a vehicle load of 950 kg is 4.39 meters. The longest braking distance is 14.78 meters at a speed of 40 km/hour with a vehicle load of 1050kg. The fastest braking time is at a speed of 20 km/hour with a vehicle load of 950 kg, namely 1.97 seconds. The longest braking time was at a speed of 40 km/h with a vehicle load of 1050 kg, namely 2.76 seconds. The smallest braking force is at a speed of 20 km/hour with a vehicle load of 1050 kg, namely 2098.36 N. The largest braking force is at a speed of 40 km/hour with a vehicle load of 950 kg, namely 4132.65 N.
