Abstract

Abstrak Kendaraan adalah suatu sarana angkut di jalan yang terdiri atas kendaraan bermotor dan kendaraan tidak bermotor sesuai dengan PP nomor 55 tahun 2012 pasal 1. Tekanan angin ban yang kurang pada kendaraan menimbulkan dampak negatif yaitu pengereman tidak maksimal. Penelitian ini membahas pengaruh perbedaan tekanan angin ban terhadap hasil pengujian rem di UPTD Pengujian Kendaraan Bermotor Wiyung Kota Surabaya, pada mobil barang Isuzu TLD 24 C bak terbuka menggunakan alat uji brake tester guna menentukan nilai pengaruh perbedaan tekanan ban terhadap efisiensi pengereman. Metode yang digunakan eksperimental pada kendaraan tanpa beban, beban < 10% JBI dan beban > 10% JBI. Efisiensi rem paling besar bernilai 80.5% dan paling kecil bernilai 41%. Nilai efisiensi rem kendaraan tanpa beban terdapat penyimpangan besar, sumbu 1 bernilai 18.8% dan sumbu 2 bernilai 8.5%. Keduanya tidak memenuhi standar yang ditetapkan JIS. Oleh karena itu, perlunya peninjauan kembali pada PM 134 tahun 2015 pasal 26 ayat 6 mengenai toleransi pemuatan beban kendaraan dan PP nomor 55 tahun 2012 pasal 67 ayat 1 mengenai kelulusan pengujian rem tidak hanya mencantumkan efisiensi rem tetapi juga mencantumkan peraturan mengenai penyimpangan rem pada kendaraan agar tidak membahayakan keselamatan di jalan. Kata Kunci : efisiensi rem, Isuzu TLD 24 C, brake tester

Abstract

The use of diesel engines in commercial vehicles is still the main choice and the most widely used. The increasing number of commercial vehicles that use diesel engines can pollute the environment and cause noise. In order to reduce exhaust emissions and noise in diesel engines, a particulate filter diesel technology was created which is installed in commercial vehicle diesel engines. This study uses an experimental method. The test was carried out on a Mitsubishi L300 commercial vehicle diesel engine type 4D56 4 cylinder with a cylinder capacity of 2477 cc. The diesel particulate filter technology uses a half honeycomb model made from galvalume plates, with variations in the addition of filters in the form of glass wool of 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams. Testing the exhaust emissions of a diesel engine using a TEN Automotive Equipment Innova 2000 multigas analyzer with a smoketester. Sound noise testing using a sound level meter test tool LT Lutron SL-4001. The test results with the addition of diesel particulate filter technology can reduce exhaust emissions and sound noise. The use of diesel particulate filter technology can reduce exhaust emissions in the form of Particulate Matter (PM) most optimally at the addition of a 100 gram filter with a decrease of 45.9%. The most optimal reduction in noise is the addition of a 50 gram filter with a decrease of 26.5%.

Abstract

Tabanan Regency is one of the regencies that is traversed by the main route connecting Gilimanuk-Denpasar so that the road is known as Jalan Raya Denpasar-Gilimanuk. The road is a National Road which is the main route connecting the districts in western Bali, namely Jembrana Regency, Tabanan Regency, Badung Regency and Denpasar City. In addition, with the increasing activities of the Tabanan community, especially those in the city of Tabanan who travel either to the city of Denpasar or to other areas, passing through this route which is the main route that serves transportation activities from Tabanan to Denpasar and vice versa. In this location there are many places that cause attraction, namely shopping centers, stalls and places of worship. Therefore, congestion on these roads often occurs, especially at peak hours of traffic flow (Peak Hour). This research was conducted on the performance of roads to determine the level of service. The data analysis process uses the method of calculating the Manual Kapasitas Jalan Indonesia (MKJI) 1997). The results showed that the Tabanan-Denpasar road, Jl Ahmad Yani, during the COVID-19 pandemic PPKM level 4 was obtained, the road capacity was 2,457 smp/hour, the free flow speed was 46.48 km/hour, the degree of saturation was 0.79, the light vehicle speed value was 36 km/hour with a travel time of 25 seconds. Based on the value of the degree of saturation on the Tabanan-Denpasar road, Jl Ahmad Yani during the COVID-19 pandemic PPKM level 4 of 0.79, then the level of service for the road was entered at Service level D.

Abstract

Under vehicle inspection is part of the vehicle inspection process and is the most important part of the vehicle because almost 80% of the most important parts of the vehicle cannot be seen directly under the vehicle. Observation of the vehicle with the help of IP Webcam with a qualitative descriptive approach. The equipment used in this study consisted of motor vehicles to be tested, Android phones handheld cameras, laptops/computers, monitors and HDMI/VGA cables, wireless/WiFi, printers. Processing of graded data with hypothesized mean. The results of the study show that an inspector can provide information about damage audio-visually and the vehicle owner can see it from the screen without having to go under the vehicle. Then 6 categories of utility values ​​were evaluated, indications of need, comfort, appearance, time to use an IP web camera at a high value/scale were obtained. Meanwhile, satisfaction and suitability on the value/moderate scale. Therefore, it can be concluded that the use of an IP web camera as a vehicle inspection tool has been successful.
