Abstract

Transportation problems in big cities in Indonesia, especially on Jalan R. Suprapto, Ketapang Regency are increasing from time to time in line with population growth, rapid growth in the number of vehicles and vehicle ownership, urbanization and an inefficient public transportation system. This has an impact on the decrease in the performance level of the road segment, including the U-Turn motion behavior at the road median opening. This study aims to determine traffic characteristics, road capacity, road service level (LOS), the average time for vehicles to perform U-turns, queue lengths and alternatives that will be applied in this study based on the 1997 MKJI guidelines. From the results of research and discussion on Jalan R. Suprapto the characteristic value of traffic flow which consists of traffic volume at rush hour from the direction of Jl. R. Suprapto – Jl. Gatot Subroto at 513.8 smp/hour and for the direction of Jl. Gatot Subroto – Jl. R. Suprapto at 651.35 smp/hour. The vehicle speed is 49.86 km/hour. Traffic density for the direction of Jl. R. Suprapto – Jl. Gatot Subroto of 10.24 smp/km and for the direction of Jl. Gatot Subroto – Jl. R. Suprapto 13.1 pcu/km. The road segment capacity is 5,422.3 pcu/hour. The value of the road service level obtained an A value.

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

Telah dilaksanakan pembangungan jembatan girder dengan profil I di Desa Kepuluk Kecamatan Sungai Melayu Rayak. Kabupaten Ketapang, sebagai salah satu alternatif dalam meningkatkan infrastruktur daerah yang baik. Pelat lantai jembatan menjadi dalah satu bagian penting karena menerima beban secara langsung baik beban hidup maupun beban mati. Oleh karena itu, dilakukan tinjauan ulang pada pelat lantai jembatan untuk mengetahui apakah terdapat perbedaan antara perencanaan dan pelaksanaan di lapangan. Tujuan penelitian ini yaitu untuk mengetahui beban maksimum yang bekerja, mengetahui momen yang terjadi, dan mengetahui desain struktur pelat lantai jembatan. Data dimensi jembatan dan data lalu lintas harian rata-rata menjedi data primer, sedangkan data faktor pembebanan pelat lantai jembatan, tabel jenis tumpuan, dan as built drawing menjadi data sekunder. Hasil perhitungan struktur pelat lantai diperoleh beban maksimum yang bekerja sebesar 6,57 kN/m2 pada alternatif 1 dan 2, nilai momen yang terjadi dari beban maksimum terdiri dari tipe VI A, III, II, dan VI B, serta dari perhitungan tulangan 16 mm arah lapangan x dan y memiliki jarak 250 mm dan tulangan berdiameter 13 mm arah tumpuan x memiliki jarak 120 mm dan y memiliki jarak 230 mm, sedangkan untuk penggunaan di lapangan diameter 16 mm dan 13 mm memiliki jarak 150 mm yang masih termasuk kategori aman karena tidak melebihi nilai kontrol tulangan.

Abstract

Ketapang Regency, West Kalimantan, is one of the regions with intensive industrial activity, particularly bauxite mining and coal-fired power plants (CFPPs), which generate large amounts of industrial waste such as bauxite tailings, red mud, fly ash, and bottom ash. To date, most of this waste has not been optimally utilized and has the potential to cause environmental issues. This study aims to conduct basic physical characterization of the four types of waste and assess their potential for utilization in concrete construction for sustainable transportation infrastructure. The methodology employed includes testing for moisture content, particle size distribution, bulk density, specific gravity, water absorption, and clay content. Test results indicate that fly ash exhibits pozzolanic properties, bauxite tailings have potential as an alternative fine aggregate, bottom ash approaches sand gradation though it requires preliminary treatment, while red mud is more suitable for use as a filler or cement substitute in limited quantities after chemical stabilization. These findings indicate that the utilization of industrial waste in Ketapang can serve as a strategic solution in supporting environmentally friendly infrastructure development while reducing dependence on conventional natural resources.
