Abstract

The increase in traffic volume is a problem that causes congestion of asection of road, especially on urban roads. The problem of congestion points generally occurs at intersections, which can be found at the intersection of four Jalan Jenderal Sudirman, Jalan Panembahan Bandala, and Jalan Basuki Rahmat which have the potential to cause accidents, queues for traffic jams and delays. The purpose of this study is to find out whether or not it is necessary to install traffic lights at the intersection. The secondary data used are ketapang regency penduduk data and a map of the research location. Primary data were obtained from direct observations in the field through geometric surveys and traffic volume surveys on Thursdays representing weekdays, Saturdays and Sundays representing holidays. Analysis data using MKJI1997. On weekdays, the afternoon capacity value (C) was2,794.13 smp/hour, traffic flow (Q) was 2.376,4 smp/hour, degree of saturation (DS) 0.85, queue opportunity (QP) of 57,40%-29,04%. On Sunday, the afternoon peak with a capacity value (C) of 2,948,14 smp/h, traffic flow(Q) of 2.680,4 smp/hour, degree of saturation (DS) 0.91, queue odds (QP) of 65,53%-33,22%.The results of the analysis at the Ketapang City Park intersection need to be carried out planning for the installation of traffic lights because it has exceeded 750 vehicles/hour for 8 hours which is one of the criteria for installing a traffic light signaling device (APILL).

Abstract

Gema Village, located in Simpang Dua District, Ketapang Regency, has significant potential in agriculture and plantation sectors but faces challenges in infrastructure quality control. This Community Service Program (PKM) aims to strengthen the technical capacity of village officials and the community in conducting effective, transparent, and sustainable construction quality supervision. The implementation methods include quality policy socialization, case-based technical training, application of on-site quality checklist systems, direct mentoring during construction activities, and performance-based evaluation. The results indicate a notable improvement in technical knowledge (from 54.3% to 79.4%), ability to create quality checklists (from 35% to 85%), and participant satisfaction (92%). The Village Empowerment Institution (LPM) is now capable of performing independent and documented quality control. The study concludes that nonformal education-based approaches significantly enhance technical literacy and infrastructure governance in rural areas. It is recommended that similar programs be conducted periodically with cross-institutional collaboration to ensure sustainability and replication of the PKM model in other villages.

Abstract

This study aims to analyze changes in the conceptual understanding of polytechnic students following the implementation of instruction that integrates metacognitive prompts into kinematics material, as well as to describe students’ metacognitive behaviors during the learning process. The study employed a one-group pretest–posttest pre-experimental design involving 32 first-semester students in the Road and Bridge Engineering Technology (TRKJJ) program at Ketapang State Polytechnic. Data were collected through conceptual understanding tests, diagnostic tests, metacognitive prompt sheets, and metacognitive behavior observation sheets. Conceptual understanding data were analyzed using normalized gain, the paired-samples t-test, the Wilcoxon signed-rank test, and Cohen’s dz effect size, while metacognitive behavior was analyzed descriptively based on the aspects of planning, monitoring, and evaluating. The results showed that the mean conceptual understanding score increased from 14.47 (36.17%) on the pretest to 29.38 (73.44%) on the posttest. The mean N-gain value of 0.59 falls into the moderate category. The difference between pretest and posttest scores was significant based on the paired-samples t-test (t(31) = 38.24, p < 0.001) and consistent with the Wilcoxon test (p > 0.001). The effect size was Cohen’s dz = 6.76. Among the metacognitive behaviors, monitoring received the highest mean score (M = 3.20), followed by planning (M = 2.80) and evaluating (M = 2.60). These findings indicate an increase in conceptual understanding following instruction that integrated metacognitive prompts, accompanied by a predominance of monitoring behavior during the learning process. However, because the study used a design without a control group, this increase cannot be fully attributed to the metacognitive prompts.
