Abstract

Perwujudan kota yang berwawasan lingkungan menjadi konsep penyeimbang aktivitas pembangunan yang kian pesat. Salah satu caranya adalah dengan memilih sarana transportasi yang lebih ramah lingkungan, dengan memilih kendaraan tidak bermotor. Sepeda merupakan moda alternatif yang ramah lingkungan sebagai alat transportasi yang dapat menggantikan kendaraan bermotor dalam upaya mengurangi dampak pemanasan global. Dimensi sepeda yang cukup mempengaruhi pengguna jalan lainnya, adapun jaringan jalan yang sangat perlu di tinjau dikarenakan mempunyai lajur khusus oleh sepeda adalah Jalan Sutan Syahrir – Jalan Jendral Urip – Jalan KHW. Hasyim – Jalan Merdeka, jalan tersebut adalah jalur penting di Kota Pontianak, sehingga perlu  dilakukan peninjauan analisis efektivitas lajur khusus sepeda. Pada penelitian ini pengambilan data primer berupa survey volume lalu lintas (LHR),survey kecepatan kendaraan bermotor, survey geometrik jalan, survey dokumentasi perkerasan jalan. Selanjutnya, data pertama yang dianalisis adalah jumlah arus lalu lintas kendaran per jam, di lanjutkan persentase kendaraan perjam, lalu kecepetan kendaraan bermotor,  kemudian dilakukan penilaian peringkat perkerasan di masing-masing jalan lokasi studi tersebut, setelahnya dilakukan analisis efektivitas dengan metode Bicycle Level Of Service (BLOS), sehingga dapat diketahui tingkat pelayanan sepeda pada masing-masing jalan lokasi studi. Sedangkan, Bicycle Level Of Service adalah metode yang paling akurat untuk menghitung tingkat pelayanan sepeda. Menggunakan lalu lintas dan jalan faktor terukur yang sama bahwa para perencana transportasi dan insinyur gunakan untuk mode wisata lainnya. Dengan presisi statistik, Model jelas mencerminkan efek pada bersepeda yang berkesesuaian atau "kompatibilitas" karena faktor-faktor seperti lebar jalan, lebar jalur sepeda dan kombinasi striping volume lalu lintas, kondisi permukaan perkerasan, kecepatan jenis kendaraan bermotor, dan parkir on street. Berdasarkan hasil analisa BLOS diketahui di jalan Jendral Urip arah Jalan Jendral Urip – Jend. Sudirman nilai BLOS “F”, arah Jendral Urip – Johar nilai BLOS “F”, di jalan KHW. Hasyim arah KHW. Hasyim – H. Rais A. Rahman nilai BLOS “F”, arah  KHW. Hasyim – KHA. Dahlan nilai BLOS “E”, di jalan Merdeka arah Merdeka – Hasanuddin nilai BLOS “F”, arah Merdeka – HOS. Cokroaminoto nilai BLOS “F”, sedangkan di jalan Sutan Syahrir arah Sutan Syahrir – Prof. M. Yamin nilai BLOS “F”, dan yang terakhir arah Sutan Syahrir – Sultan Abdurahman juga didapat nilai BLOS “F”. Dengan demikian, berdasarkan nilai BLOS perlu diadakan rekayasa lalu lintas di masing-masing jalan tinjauan lokasi studi.   Kata Kunci :     Lajur Khusus Sepeda, Persentase Kendaraan Berat, Peringkat Perkerasan.

Abstract

Indonesia is the world's largest producer of palm oil, with a production of 36 million tons in 2019. The construction of palm oil mills is expected to have an impact on the environment and traffic, including public attitudes, traffic flow, congestion, and safety. According to Minister of Transportation Regulation No. 17 of 2021, a traffic impact analysis is mandatory for developments that have the potential to cause disruptions, in order to assess the impact of palm oil mill construction. This study examines the impact of palm oil mill construction on traffic, particularly the influence of the Degree of Saturation (DS) and Level of Service (LOS). The research methodology includes data collection, road performance analysis using the 1997 Indonesian Highway Capacity Manual (MKJI), and micro-traffic simulation to evaluate road network performance and the transportation system. This study also employs four stages of traffic modeling as an analytical method. The analysis results indicate that in zones with the Do-Something scenario based on approach type and cycle time, the Degree of Saturation (DS) decreases annually, while the Level of Service (LOS) remains unchanged. Meanwhile, in zones with the Do-Something scenario based on geometric improvements, significant improvements are observed, with an increase of 29.3% on Jalan Raya Pulau Bendu and 13.8% on Jalan Raya Ngabang – Sanggau. However, the Level of Service (LOS) remains unchanged..

Abstract

This study presents an integrated approach to optimizing urban drainage infrastructure in Gg. Smile, West Pontianak—a flood-prone area facing increased hydraulic and environmental stress due to urbanization. Field observations revealed significant degradation in earthen drainage channels, prompting the development of a hybrid system that combines reinforced concrete with ecological features. The proposed design, implemented over six weeks, utilized concrete sheet piles, crossbeams, and biofiltration zones, resulting in a 300% increase in hydraulic capacity while maintaining 40% of the original infiltration potential. IoT-based monitoring systems were embedded for real-time flow surveillance and predictive maintenance. Cost analysis revealed financial feasibility, with material efficiency and safety compliance maintained throughout the project. Post-construction evaluation confirmed a 40–60% reduction in pollutant loads and a 25% increase in groundwater recharge. The successful use of the S-curve for progress monitoring and resource allocation validated the project’s management strategy. This study advocates for the replication of hybrid grey-green drainage systems across tropical urban centers, integrating structural resilience with environmental sustainability and intelligent monitoring.

Abstract

Traffic Impact Analysis involves assessing the effects caused by traffic resulting from the development of a particular area on the nearby transportation system. This study aims to evaluate the performance of road sections around the Swiss-Belhotel Pontianak vicinity. To achieve the goals and objectives of the study, it is necessary to develop a methodology that can systematically integrate all stages of the work process. Primary data is defined as data obtained through direct measurement or observation at the study location. Meanwhile, secondary data refers to data collected from other parties (individuals, agencies, institutions) without the need to conduct direct measurements or observations on-site. Based on the analysis results above, the performance of the existing road segments (weekend) shows the highest Volume to Capacity Ratio (VCR) on Pahlawan Street, reaching 1.02, with a Level of Service (LoS) of F. Meanwhile, the existing road performance in (weekday) indicates that the highest VCR is on Gajahmada Street, reaching 1.40, also with a Level of Service F. Based on the analysis, it can be concluded that due to the large number of road segments with poor Level of Service (LoS), several Do-Something scenarios need to be implemented to improve the LoS after the existing year. In this study, several recommendations are proposed to enhance the LoS, such as installing additional traffic signs and road markings or widening certain road segments.

Abstract

One of the negative impacts of modern transportation development is the increasing number of traffic accidents, including the rising fatality rates, resulting in serious injuries and loss of life. The low level of traffic safety remains a significant challenge for the government in realising a safe and orderly transportation system. This study aims to identify and categorise the factors that influence the safety level at unsignalized four-legged intersections in Pontianak City. The Research focuses on two intersections: Putri Daranante – Putri Darahitam – Alianyang Street (Intersection 1) and Harapan Jaya – Ampera – Prof. M. Yamin Street (Intersection 2). Data were collected through field surveys using the Traffic Conflict Technique (TCT), based on the Swedish Traffic Conflict Technique and PIARC guidelines. The analysis results indicate that the Time-to-Accident (TA) parameter is the main factor influencing traffic safety levels at both study locations. Intersection 1 exhibited more serious conflict conditions, with TA values ranging from 0.0 to 0.5 seconds and conflicting speeds between 40 and 45 km/h. This study recommends implementing traffic signals and enhancing traffic sign dissemination and enforcement to reduce the number of serious conflicts.

Abstract

Segara Anakan is a semi-enclosed lagoon that serves as a transitional zone between fluvial and marine environments, characterized by complex, dynamic morphological features. The hydrodynamic conditions in this area strongly influence sediment transport and deposition, which, in turn, affect the morphological evolution of the lagoon over time. This study aims to analyze current patterns and bottom sediment distribution in Segara Anakan and to identify the relationship between current dynamics and sediment characteristics. The data used include primary data from bottom sediment sampling at 21 observation stations and secondary data on bathymetry, tides, and river discharge. Current modeling was conducted using the Surface-water Modeling System (SMS) with the RMA2 module, while sediment analysis was conducted using a grain-size test by the sieve method. The modeling results show that the maximum current velocity reaches 0.907 m/s, with flow directions varying according to the lagoon’s morphology. Sediment analysis results indicate that sand is the dominant fraction at 13 stations, while mixed sediments are found in the central part of the lagoon. These findings suggest that tidal current strength plays a significant role in controlling sediment transport and deposition patterns within the Segara Anakan lagoon.

Abstract

This study examines public transportation accessibility in Bandung, the capital of West Java Province, located at 107 °36' E and 6 °55' S, covering 167.31 square kilometers and characterized by a mountainous "bowl-shaped" topography. Trans Metro Bandung (TMB) operates an integrated network of five main corridors and two feeder routes to enhance urban mobility. Corridor 1, the longest route, spans approximately 20 kilometers from Cibiru Terminal in the east to Cibeureum Terminal in the west, passing through major roads and serving 86 bus stops distributed across educational, commercial, office, and residential areas. The study utilizes secondary spatial data, including Bandung"™s road network and bus stop locations from the Trans Metro Bandung. Administrative boundary data delineates the study area. Using GIS software, the research compares two accessibility measurement methods: the circular buffer, which creates fixed-radius catchment areas around stops, and the service area buffer, which calculates accessible areas based on the actual street network. Both buffer types are merged to remove overlapping areas, producing union buffers representing unique coverage zones. Accessibility indices are calculated based on the union buffers: the Ideal Stop-Accessibility Index (ISAI) measures the ratio of circular buffer coverage to the ideal corridor buffer; the Actual Stop-Accessibility Index (ASAI) measures the ratio of service area buffer coverage to the ideal; and the Stop Coverage Ratio Index (SCRI) compares service area coverage to circular buffer coverage. These indices prevent overestimation caused by overlapping buffers and provide a realistic assessment of transit stop accessibility. This study provides valuable insights for developing more accurate and sustainable public transportation strategies in Bandung and similar urban contexts.
