Abstract

Pertumbuhan jumlah kendaraan bermotor di Kabupaten Garut menimbulkan kemacetan pada simpang bersinyal, terutama di Simpang Maktal yang menjadi penghubung pusat kota dengan jalur menuju wilayah selatan. Penelitian ini bertujuan menganalisis kinerja simpang sebagai dasar penerapan Area Traffic Control System (ATCS). Metode penelitian menggunakan pendekatan kuantitatif melalui survei lapangan pada jam puncak sore untuk memperoleh data volume lalu lintas dan rasio belok. Analisis kinerja dilakukan secara manual berdasarkan Pedoman Kapasitas Jalan Indonesia (PKJI 2023) yang meliputi perhitungan arus jenuh, kapasitas, derajat kejenuhan, tundaan, panjang antrean, dan tingkat pelayanan, serta dibandingkan dengan hasil simulasi menggunakan perangkat lunak PTV VISSIM Student Version 25. Hasil penelitian menunjukkan bahwa volume tertinggi terjadi pada pendekat B dengan derajat kejenuhan lebih dari 0,9, yang menandakan kondisi hampir jenuh. Perhitungan manual menghasilkan tundaan rata-rata sebesar 60 detik detik per satuan mobil penumpang dengan tingkat pelayanan D - F, sedangkan simulasi menunjukkan tundaan lebih tinggi pada setiap pendekat hingga mencapai tingkat pelayanan F. Temuan ini mengindikasikan bahwa penerapan ATCS berpotensi mengoptimalkan distribusi waktu hijau, menurunkan tundaan, serta meningkatkan efisiensi kinerja simpang bersinyal di Kabupaten Garut. Penelitian ini diharapkan dapat memberikan kontribusi dalam bidang rekayasa lalu lintas, khususnya pengembangan transportasi cerdas berbasis evaluasi kinerja simpang dan simulasi mikroskopis.

Abstract

Traffic accidents that frequently occur on the Patrol-Kamojang road section in Bandung Regency indicate a high safety risk due to the incompatibility of geometric conditions, particularly vertical alignment, with applicable technical standards. This study aims to analyze the characteristics of vertical alignment on this section, assess its effect on accident rates, and provide recommendations for improvement. Primary data was obtained through field surveys in the form of measurements of elevation, segment length, and slope using a theodolite, measuring rod, and tape measure. Secondary data consisted of a recapitulation of accidents from 2022 to 2024 from the police, including the frequency, location, and type of accidents. The analysis was conducted by comparing the geometric data with Bina Marga standards, calculating the accident rate using the Equivalent Accident Number (EAN), and setting the Upper Control Limit (UCL) for blackspot identification. In addition, the critical length and geometric adjustment requirements were calculated as the basis for technical recommendations. The results of the study show that several segments have a slope of up to 33.84%, exceeding the safety limit and correlating with an above-average EAN value and exceeding the UCL, thus being designated as priority blackspots. This study identifies accident-prone locations and recommends vertical alignment improvements, and can be used as a reference for relevant agencies in improving traffic safety on hilly roads.

Abstract

The Sirnajaya–Papandayan road segment in Cisurupan District, Garut Regency, serves as a primary access route to mountainous tourist areas and is characterized by winding alignments, steep ascents, and sharp descents. These characteristics, combined with limited road width, pavement deterioration, and inadequate safety facilities, make this segment highly prone to traffic accidents. This study aims to analyze the geometric conditions of the road, evaluate their influence on accident rates, and formulate improvement recommendations to enhance road user safety. The research methodology includes surveys of existing conditions, geometric road measurements, accident analysis using the Equivalent Accident Number (EAN) and Upper Control Limit (UCL) methods, and evaluation based on the 2021 Bina Marga geometric design standards. The analysis results indicate the presence of sharp curves with small radii that generate high EAN values, namely 256 for horizontal curve 1 and 288 for horizontal curve 2. In terms of vertical alignment, the segments at STA 0+410–0+420 recorded an EAN value of 15 and STA 0+460–0+470 recorded a value of 12; both exceed the threshold and are classified as black spots. Furthermore, several segments exhibit gradients exceeding 20%, far surpassing the 10% maximum specified by the 2021 Bina Marga standard for collector roads in mountainous areas. Combined with pavement damage and insufficient warning signage, these conditions significantly increase the risk of traffic accidents. In conclusion, improvements are required through the redesign of horizontal and vertical alignments, pavement rehabilitation, and the installation of warning signs, road markings, guardrails, and street lighting. This study provides a scientific basis for road planning and safety enhancement in mountainous regions and can serve as a reference for relevant authorities in addressing road segments with similar characteristics.

Abstract

Early pavement damage is often caused by non-optimal asphalt mix composition, particularly related to filler selection. This study analyzes the effect of partial substitution of stone ash filler with silica (SiO2) on the Marshall characteristics of AC-WC asphalt mixtures using a quantitative experimental method. Marshall testing was conducted with silica contents of 0%, 2%, 4%, and 6% at an Optimum Asphalt Content of 6.3%, referring to the 2018 Bina Marga Specifications. The results show that silica contents of 2% and 4% satisfy all Marshall parameters, with stability values of 1011 kg and 950 kg, flow values of 2.97 mm and 3.43 mm, VIM of 3.62% and 4.17%, VMA of 16.22% and 16.70%, VFB of 78.88% and 79.26%, and MQ of 340.89 kg/mm and 276.72 kg/mm, respectively. The main contribution of this study is the identification of an overfilling mechanism at silica contents >=6% that leads to reduced stability. Practical implications indicate a potential material cost savings of 15-20% and the feasibility of silica as an alternative renewable filler, although durability performance (IKS of 89.28% and 69.91%) still requires improvement through anti-stripping treatment for long-term applications.

Abstract

Background: Road infrastructure development plays a crucial role in fostering economic growth and improving interregional connectivity. However, uneven distribution of benefits can generate or intensify existing social disparities. Objective: This study aims to analyze the role of community-based routine provincial road maintenance in mitigating social inequality by evaluating maintenance implementation and assessing community participation patterns. Methods: This study employs a mixed-methods quantitative-evaluative design across 20 provincial road sections in nine districts of West Java Province. Data were collected from 89 respondents for the routine maintenance variable and 140 respondents for the community participation variable. Results: The evaluation results indicate that all routine maintenance variables fall within moderate to excellent categories, except for the labor factor, which scored poorly (1.65) due to limited availability of certified skilled workers. For community participation, all variables scored moderate to excellent, except the willingness to contribute financially (1.83), largely influenced by low household income. SEM analysis identifies significant variables including shoulder damage level, labor factor, community attendance in meetings, and participatory contributions. Conclusion: The study concludes that social disparities can be mitigated by increasing community income through operational cooperation between government and villages, enabling communities to participate in routine maintenance—particularly in simple tasks requiring trained local labor.

Abstract

Inorganic waste management remains a significant environmental challenge in rural areas. This Community Service Program (PkM) aimed to evaluate the effectiveness of an educational intervention on inorganic waste management in improving the knowledge and attitudes of residents in Sirnajaya Village, Garut. The program was conducted on February 4, 2026, in collaboration with the Garut Zero Waste community using a pre-test and post-test design involving 18 participants, consisting of housewives, university lecturers, and community members. The assessment instrument covered five indicators: understanding the definition of inorganic waste, identifying examples of inorganic waste, recognizing the environmental impacts of improper waste disposal, attitudes toward waste segregation, and intentions to reduce the use of single-use plastics. The results showed that 83.3% of the participants already possessed a high level of baseline knowledge. Consequently, the improvement in post-education scores was relatively limited, with an average normalized gain (N-Gain) of 0.11. This finding reflects a common ceiling effect, rather than indicating the ineffectiveness of the educational program. Nevertheless, three out of eighteen participants with lower initial knowledge demonstrated substantial improvements, achieving moderate to high levels of learning gain. Overall, the program contributed primarily to strengthening participants' knowledge and behavioral intentions regarding inorganic waste management. However, measurable changes in actual household waste management practices require further medium-term observation and follow-up evaluation.
