Penentuan Fase dan Waktu Siklus Optimum Simpang Bersinyal dengan Graf Kompatibel dan Webster Modifikasi (Studi Kasus: Persimpangan Sokaraja, Banyumas)
Get PDFTraffic congestion at signalized intersections can be reduced through proper signal timing. This study aims to optimize traffic-signal settings at the Sokaraja intersection, Banyumas Regency, using a directed compatibility graph and a modified Webster method. Primary data collected from October 2025 to Desember 2025 include intersection geometry (approach widths), existing signal timings, and traffic volumes (heavy vehicles, light vehicles, and motorcycles) observed over two weeks during morning, midday, and afternoon periods. Traffic movements were modeled using a directed compatibility graph to identify non-conflicting movements that can run simultaneously; weighting based on approach width and traffic volume was then used to form phases and allocate green splits. The modified Webster calculation yields an optimal cycle length of 149 s for the maximum-demand condition (and 35 s for the minimum-demand condition). Compared with field timings (e.g., red/green 117/70 s on Jl Jendral Soedirman and 137/22 s on Jl Ajibarang–Secang), the recommended timings under maximum demand are 50/86 s and 81/54 s, respectively. Effectiveness evaluation indicates that the red intervals on Jl Jendral Soedirman and Jl Ajibarang–Secang are longer than required, while the other approaches are closer to the optimized settings. These results provide a practical basis for signal retiming and for developing more adaptive control at the Sokaraja intersection

SUSTAINABLE BUILDING MATERIAL COMPARISON BETWEEN THAILAND AND INDONESIA – TARBIATULWATAN MULNITI SCHOOL, PATTANI
Get PDFThis study compares sustainable building materials used in Thailand and Indonesia, focusing on the case of Tarbiatulwatan Mulniti School in Yala, Thailand, as part of an international community service (KKN Internasional) program. The research aims to identify the differences in material selection, sustainability performance, and cultural adaptation in both countries. The methods used include field observation, literature review, and comparative analysis based on material efficiency, environmental impact, cost, and social acceptance. The results show that Thailand adopts more sustainable materials, such as Autoclaved Aerated Concrete (AAC) blocks, light steel trusses, and energy-efficient coatings, supported by national policies like the Thai Green Building Standard (TGBS). In contrast, Indonesia still relies on traditional red bricks and reinforced concrete, which are cheaper and widely available but less environmentally friendly. The study concludes that Thailand’s approach demonstrates stronger integration of policy, technology, and cultural awareness toward sustainability, while Indonesia’s construction practices remain cost-oriented. The research recommends that Indonesia strengthen green building policies, improve public awareness, and promote cross-national collaboration to accelerate sustainable construction development
ANALYSIS OF THE INSTALLATION METHOD OF HALF SLAB PRECAST ON KARANG SINGA BEACON TOWER BUILDING
Get PDFABSTRACT
Innovation in construction methods is increasingly needed, especially in projects in extreme geographical conditions. This study analyzes the effectiveness of the precast half slab installation method in the Liang Liang Coral Beacon Tower Construction project in the Riau Islands, which is located ±4 nautical miles from Bintan Island, so that it does not allow the application of conventional casting. The half slab precast method was chosen to overcome the limitations of the working area, weather risks, and the need to accelerate construction time. The analysis was carried out through the stages of half slab design planning, fabrication, material distribution using a service barge, to the erection process using a crawler crane. The technical data of the half slab includes the configuration of HS1, HS2, and HS3 with a thickness of 200 mm and a concrete topping of 150 mm. The results of the analysis showed that the precast half slab met the technical requirements based on SNI 2847:2013 and the PCI Design Handbook, both in terms of lifting load capacity, bending moment control, and deformation during installation. The installation method has also proven to be efficient in terms of time and cost because it minimizes the use of formwork, reduces the risk of wet work at sea, and accelerates the implementation of erections. This study concludes that the half slab precast method is an effective and efficient solution for floor structure work in offshore projects, especially in locations with limited access and challenging environmental conditions
EFFECT OF GREEN INNOVATION ON RENEWABLE ENERGY CONSUMPTION IN NIGERIA
Get PDFRenewable energy plays a critical role in addressing global energy needs while mitigating climate change. With an emphasis on carbon intensity, domestic credit to the private sector, and electricity accessibility, this study investigates how green innovation affects Nigeria's use of renewable energy. The study uses secondary data from the World Bank Development Indicators (WDI) for the years 1990–2023 and employs an ex post facto design. The statistical link between the dependent variable, renewable energy consumption, and the independent variables, such as carbon intensity (CI), domestic credit to the private sector (DCPS), and access to electricity (AE), is evaluated using a multiple regression analysis. The results show that carbon intensity has no discernible effect on the use of renewable energy, indicating that the adoption of renewable energy is not solely influenced by emissions reduction. Investment in sustainable energy is increased with support. Conversely, access to electricity negatively affects renewable energy consumption, implying that grid expansion may reduce reliance on renewable sources. These results highlight the critical role of financial incentives in promoting renewable energy while underscoring the need for strategic electrification policies. The study recommends that policymakers introduce low-carbon technology incentives, enhance green financing through low-interest loans, and prioritize decentralized renewable energy solutions, such as off-grid solar systems, to ensure sustainable electrification. This information contributes to the broader discourse on green innovation and energy sustainability in Nigeria, offering empirical guidance for policymakers and investors
