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.

Abstract

Nanopartikel Nikel Ferit (NiFe2O4) telah disintesis dengan metode kopresipitasi dengan memvariasi konsentrasi NaOH dan suhu sintesis. Struktur kristal, ukuran partikel, dan morfologi dari sampel dianalisa menggunakan X-ray diffraction (XRD) dan transmission electron microscopy (TEM). Ukuran butir pada konsentrasi NaOH 3, 5, dan 10 M masing-masing adalah 5,7; 4,3; dan 4,2 nm, sedangkan pada suhu 60, 80, dan 150°C berturut-turut adalah 4,2; 4,9; dan 5,5 nm. Analisa fourier transform infrared (FTIR) menunjukkan dua puncak serapan pada rentang ~400-600 cm-1 yang terkait dengan site oktahedral dan tetrahedral pada struktur NiFe2O4. Sifat magnetik NiFe2O4 hasil analisa vibrating sample magnetometer (VSM) menunjukkan bahwa sampel berperilaku ferromagnetik dengan nilai koersivitasnya pada rentang 42-47 Oe. Sampel dengan variasi konsentrasi NaOH, koersivitasnya cenderung menurun dengan menurunnya ukuran partikel. Sementara sampel dengan variasi suhu, semakin kecil ukuran partikel, koersivitasnya cenderung meningkat. Pada 15 kOe, nilai magnetisasi terbesar (6,17 emu/g) diperoleh pada sampel dengan rasio fasa α-Fe2O3 paling rendah.

Abstract

High side barriers cause road sections to experience traffic jams. On the Pantura road, Brebes Regency, many vehicles tend to stop or reduce their speed due to many side obstacles that interfere with the journey, including tricycles, parking vehicles and so on. This study aims to analyze the behavior of motorists on each type of motorized vehicle against side obstacles. The research method is carried out directly by observers and is qualitative in nature based on normative standards in the 1997 MKJI. The results of the research show that the driver's behavior is influenced by side barriers, in this case the vehicle speed that the larger the side obstacle class, the lower the vehicle speed. On roads with a higher left lane speed than the right lane, on that road heavy vehicles tend to choose the right lane, this condition is because heavy vehicles avoid side obstacles in the left lane and on the left lane more light vehicles pass. On the other hand, on roads with a higher right-hand lane speed than the left lane, heavy vehicles that pass tend to choose the left lane for this condition because the side barriers in the left lane do not have a major effect on traffic on that lane.

Abstract

Surveys were carried out on efforts to identify safe driving behavior for drivers using the Pejagan - Pemalang toll road. This is done to determine patterns of driving behavior, especially to identify the effect of understanding safe driving on aggressive driving behavior. The research method used is a quantitative descriptive method with accidental sampling with the independent variable safe driving and the dependent variable aggressive driving. The roughness value for the Pejagan – Pemalang toll road was obtained > 0.33 µm and the unevenness value was 4.95, Tegal access. Data on maximum speed (v) and 85th percentile speed for class I vehicles, i.e. 166.09 km/hour and 115.68 km/hour. Out of 100 respondents, 77% of respondents understood safe driving, but in driving behavior 89% showed aggressive driving behavior. This means that it is necessary to practice safe driving behavior, especially when going through the toll road. From the results of the interviews, it was found that the stretches of toll roads are monotonous, silent, and to overcome drowsiness are the reasons for drivers to drive above 100 km/hour, which shows that the driver is behaving aggressive when driving.
