Analisis Geometrik Jalan Raya dengan Pendekatan Bina Marga (Studi Kasus : Jl. Poros Tikungan SP 4, Kelurahan Makbalim, Kilometer 37, Kabupaten Sorong)

The purpose of road geometry planning is to produce safe infrastructure and the maximum efficiency of traffic flow services. It can maximize the ratio of the level of use of the implementation cost on the road. The condition of Jalan Poros, Bend SP 4, Sorong Regency is a straight road and there are several steep and sharp bends, so it becomes one of the factors for accidents. Slippery road conditions are also often a factor in accidents for two-wheeled users. The purpose of this study is to analyze and describe the condition of the road geometry and also to evaluate the horizontal curve (bend) on the SP 4 bend axis road section and whether it is appropriate based on the 2020 Bina Marga Guidelines. The research method used is quantitative research. The primary data used in this study are road geometric data, environmental conditions, topographic maps, road width, and curve length. The secondary data are plan speed data, bend coordinate data, and plan drawings. The value of e in calculating the distribution curve coefficient f and e gives a value of 8.75%, while the value of Lc (calculating the length of the transition curve) = 207.07 m. The requirement for the spiral-circle-spiral curve is Lc ≥ 20m so this curve can be designed as a spiral-circle-spiral curve. The SP 4 bend in Sorong Regency has a flat terrain type. Based on calculations, the value of Lc = 206.893 and the value of Ls = 29.76. Both values are more than 20m, so they meet the requirements of a type bend.                                       &nbsp

Enhancing physics experiment skills using smartphone sensors for teachers in sorong regency

This community service program designed to enhance physics experimental skills using smartphone sensors for high school teacher aims to introduce and train teachers in utilizing simple yet effective technology in physics education. By using smartphone sensors, the goal is to enable teachers to conduct experiments that are not only captivating but also easily accessible and relevant to daily life, thus boosting students’ comprehension and interest. The program was conducted in two phases: first, a training session for teachers, followed by school visit with MGMP team to provide hands-on support, address any challenges teachers may encounter, and observe the implementation of the method. Furthermore, the effectiveness of the program was evaluated based on the results from both pre-assessment and post-assessment conducted on 20 teachers from MGMP group. The assessment results showed increases in understanding and preparing technology, collecting data, and analyzing and evaluating data. Despite several challenges such as limited access to compatible devices and varying levels of understanding regarding the concept, the training was overall successfully improved teachers’ skills in applying the technology for physics experiment
