ANALISIS LOKASI RAWAN KECELAKAAN REM BLONG

Repeated brake failure accidents occur on the Buntu-Banyumas Road section, which features a 1 km downhill geometric condition. The braking force required increases with a vehicle's weight, speed, and elevation. This research aims to identify the causes of brake failure accidents related to the long downhill geometric condition of the road. The methods include fault tree analysis, road accident mapping, and safe speed calculation. The data used have road geometric data, vehicle speed, and vehicle weight. The research findings indicate that brake failure accidents on the Buntu-Banyumas Road section are caused by driver behavior, repeatedly applying brakes on a road with a slope exceeding the critical maximum gradient, leading to overheating and brake failure. Road authorities must maintain guardrails, install speed limit signs, and implement emergency escape ramps.

LEVEL BERPIKIR METAKOGNISI MAHASISWA SELAMA PERKULIAHAN ONLINE DI MASA PANDEMI

The ability to reflect on yourself or think metacognition is very important for students. Because with this ability students can learn to analyze their mistakes or weaknesses to be corrected and developed in the future. During the pandemic, lectures were carried out online, this resulted in a tendency for students to not seriously attend lectures. The absence of direct supervision from lecturers is one of the reasons this can happen. Thus, researchers assume that the level of metacognition of students who carry out lectures online will also decrease. Therefore, the purpose of this study is to analyze the level of student metacognition during online lectures that have been implemented. Researchers used a qualitative descriptive research approach with a survey method. The research subjects were 120 students who had attended online courses at least 8 meetings or 2 months. The results showed that 83 students were at the lowest level of metacognition (Tacit Use). Meanwhile, students who are at the highest metacognition level are 2 students (Reflective Use). Thus, researchers can conclude that the level of student metacognition during online lectures is still very low

How Do Prospective Teachers Argue in Focus Group Discussion? Toulmin's Argumentation Study

Students’ argumentation ability is necessary for education today, which emphasizes the student-centered learning process. One way to see students’ argumentation ability is by having a discussion. Therefore, this study aimed to describe the Toulmin argumentation process for students during focus group discussions (FGD). This research is qualitative. The data collection instrument used was an open-ended questionnaire assisted by Google Form that contained common problems of the distance learning process during a pandemic. The subjects of this study consisted of fifty students from the University of Mataram. The results showed that the argumentation process was divided into three categories. The first category was the one-sentence argument. There were 58 %, or 29 students, who belonged in this category. The second category was the two sentences argument. There are 30 %, or 15 students belonged in this category. Lastly, 12 % or six students belonged to the more than three sentence argument category. The results of this study indicated that many students could not provide complete arguments. Thus, the role of lecturers is significant to improve students’ ability in providing complete argumentations. Therefore, the researchers suggest that lecturers should apply learning models that invite students to argue and discuss

Kajian Manajemen Lalu Lintas di Kawasan Pasar Bogor

Kota Bogor menjadi kota dengan jumlah kemacetan tertinggi ketiga di Provinsi Jawa Barat setelah Bandung dan Tasikmalaya. Banyaknya aktivitas warga Bogor di sekitar kawasan pasar mengakibatkan kawasan Pasar Bogor mengalami kemacetan seperti hambatan samping badan jalan, parkir dan bongkar muat, banyaknya PKL yang menjajakan dagangannya di badan jalan dan pejalan kaki menyebabkan kapasitas jalan di kawasan Pasar Bogor berkurang dan banyak terjadi tundaan kendaraan, pada ruas Jalan Suryakencana dan Jalan Roda terdapat kawasan pertokoan dan lapak pedagang dengan lokasi parkir yang berada di jalan (on street). Metode analisis yang digunakan dalam penelitian ini adalah metode Manual Kapasitas Jalan Indonesia (MKJI) 1997 untuk mengukur kinerja ruas jalan, kinerja simpang dan analisis parkir. Selanjutnya, menghitung kapasitas jalan berdasarkan perhitungan kinerja setelah penanganan dengan kondisi sama seperti eksisting. Dengan dilakukan manajemen lalu lintas, diperoleh peningkatan kapasitas jalan pada ruas Jalan Suryakencana dana Jalan Roda. Kondisi eksisting kapasitas pada Ruas Jalan Suryakencana adalah 1841 smp/jam dan Ruas Jalan Roda adalah 1841,79 smp/jam. Manajemen lalu lintas yang diterapkan pada kedua ruas tersebut adalah manajemen kapasitas dengan penanganan perubahan sudut parkir dari 60ﹾ menjadi 0ﹾ, maka lajur efektif jalan menjadi 3,5 meter dengan kapasitas jalan meningkat menjadi 3135 smp/jam dan 2117 smp/jam

The Relationship between Overloading and Over Dimension of Freight Vehicle

The freight vehicle, as the primary mode of goods distribution, has a relatively small carrying capacity.  However, it is forced to be able to meet the demand. As a result, many business actors overload their freight vehicles to reduce transportation costs. In organizing the transportation of goods, the indications are such violations in vehicle dimensions (over dimensions) in line with the business actors' vehicle overload. This study aims to determine the effect of over-size on an overload of the freight vehicle. This study's research method is a quantitative method that used a survey technique to collect the data and used the statistical method of regression and correlation as the analysis method. The study results reveal that the level of overloading at Widang weighbridge reached an average of 44.72% per day. In comparison, the level of overloading at the Losarang weighbridge reached 87.85% per day. The vehicle dimension measurement survey results showed that from 159 vehicle samples, there were 107 over-dimension vehicles in the form of length, width, and height, and there were 32 vehicles, which increased their tire size. The statistical analysis of regression and correlation tests showed that only the addition of the maximum vehicle dimensions, which had a significant effect on the overweight
