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

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.

Abstract

High intensity rainfall that occurs can cause puddles if the condition of the drainage system is not well maintained. The development of Pontianak City Infrastructure has resulted in land use changes that was originally in the form of vacant land converted into residential areas or other economic activities. The existing condition of the drainage channel at M. Sohor Road is not able to accommodate rainwater discharge in the rainy season. In the existing conditions for land use, there is no rainwater catchment area. The management of floods with arranging the drainage system has been ineffective so we need an environmentally drainage system arrangement concept.  Identification of the hydrological and hydrolic conditions that exist in the catchment area of the M. Sohor channel is required. The hydrological analysis in this study includes testing the consistency of rainfall data in Pontianak City, selecting a rain distribution that matches the rainfall data pattern, calculating the time concentration, rainfall intensity and the total discharge from domestic discharge and design discharge of 2, 5, 10 years. The hydraulic analysis in this study includes the design of a channel cross section design as a channel normalization plan. The total flow discharge in M.Sohor channel for a 2-year return period is 2.22 m3/s, a 5-year return period of 2.75 m3/s and a 10-year return period of 3.09 m3/s. Environmental insight drainage can be done by planting shrub plants that can reduce air pollution such as Croton and Bougainvillea, arranging M. Sohor Road to be friendly with pedestrians controlling excess rainwater discharge caused by the rain process through rain water harvesting techniques.

Abstract

Curah hujan dengan intensitas tinggi yang terjadi dalam beberapa waktu bisa menimbulkan genangan jika kondisi sistem drainasenya tidak terpelihara dengan baik. Perkembangan infrastruktur di Kota Pontianak memberikan dampak perubahan tata guna lahan yang mengakibatkan lahan yang semula berupa ruang hijau beralih fungsi menjadi kawasan permukiman dan kegiatan ekonomi lainnya. Kondisi eksisting saluran drainase atau parit di Jalan M. Sohor tidak mampu untuk menampung debit air hujan pada musim penghujan. Pada kondisi eksisting lahan di Kota Pontianak sudah tidak terdapat ruang resapan air hujan atau ruang terbuka hujan. Penataan sistem drainase Kota Pontianak dengan hanya menata drainasenya saja sudah tidak efektif lagi sehingga memerlukan konsep penataan sistem drainase yang berwawasan lingkungan. Maka dengan kondisi tersebut diperlukan indentifikasi terhadap kondisi hidrologi dan hidrolika yang ada di daerah tangkapan hujan Parit M. Sohor. Analisis hidrologi pada kajian ini meliputi pengujian konsistensi data hujan di Kota Pontianak, memilih distribusi hujan yang cocok dengan pola data hujan, menghitung waktu konsentrasi, intensitas curah hujan serta debit total rencana yang berasal dari debit buangan domestik dan debit rencana 2, 5, 10 tahun. Analisa hidrolika pada kajian ini meliputi pembuatan desain penampang saluran rencana sebagai rencana normalisasi saluran. Debit total di Parit M.Sohor untuk periode ulang 2 tahun adalah 2,22 m3/s, periode ulang 5 tahun sebesar 2,75 m3/s dan periode ulang 10 tahun sebesar 3,09 m3/s. Penataan drainase dengan konsep berwawasan lingkungan mengedepankan penataan drainase yang ramah lingkungan dengan menanam tanaman perdu yang dapat menahan erosi permukaan seperti tanaman Puring dan Bogenvil dan mereduksi polusi udara, menata Jalan M. Sohor mengendalikan debit air hujan berlebih yang diakibatkan oleh proses hujan melalui teknik rain water harvesting.
