<![CDATA[This study analyzes the impact of U-turns on potential traffic accidents along Kaligangsa Highway, Tegal City, using the Traffic Conflict Technique (TCT) method. Although U-turns play a crucial role in road geometric planning, they often become critical points that may lead to accidents due to sudden vehicle maneuvers. The TCT method is applied to assess potential traffic conflicts based on vehicle speed, distance between vehicles, and road user interactions. Direct observations were conducted at several U-turn locations along the road. The analysis results indicate that the presence of U-turns significantly contributes to an increased risk of accidents, particularly during peak hours and at locations with suboptimal geometric design. Non-standard U-turn designs, unclear traffic signage, and undisciplined driver behavior further escalate the risk of traffic conflicts. Therefore, this study recommends improvements in U-turn design, enhanced traffic monitoring, and driver education to improve road safety..]]>

<![CDATA[The Bank Indonesia Gresik project, especially in the Khazanah area, has high formwork requirements for the wall elements. Payment to subcontractors is made without down payment and using a 45-day term system after invoice and work progress. The purpose of this study is to compare the cost and time efficiency between conventional and semi-system formwork methods. The research method used is the comparative method, with cost and time analysis on 11,736.48 m² of wall work. Conventional formwork uses materials such as plywood and meranti wood, while the semi-system method uses hollow and phenolic frames. The results showed that the cost of the conventional method was IDR 2,438,396,000, while the semi-system method was only IDR 1,425,760,695. In terms of time, the conventional method takes 187 days, while the semi-system method only takes 131 days. The semi-system method provides time efficiency of 29.95% and cost efficiency of up to 41.53%. In conclusion, the semi-system formwork method is more efficient in terms of cost and time than the conventional method, so it is more feasible to apply to the wall formwork work of the Bank Indonesia Gresik Area Project.]]>

<![CDATA[Pavement damage can occur due to excessive traffic loads, extreme weather and so on which have an impact on hampering surrounding activities so that road users feel less safe and less comfortable. Road damage also occurs on the Babat - Bts Jombang Regency road section. To keep the road condition in good performance, it is necessary to evaluate it with a road condition survey. In processing the data from the road condition survey, UPT Pengelolaan Jalan dan Jembatan Surabaya uses the Provincial / Regency Road Management System (PKRMS) application as a database for planning purposes that holds condition data, inventory, project data, historical data, and maps. The result of this PKRMS is statistical report data on road damage conditions with the Treatment Trigger Index (TTI) calculation method. From the observation locations reviewed, the results show that the Babat - Bts Jombang Regency road section which has a section length of 30.785 kilometers and a road width of 7 meters is in a stable condition with a percentage of 83.81% or along 25.88 kilometers and 16.19% or 5 kilometers is in a less stable condition.]]>

<![CDATA[The traditional market of Meulaboh, West Aceh is a vital economic centre, but its activities put significant pressure on the surrounding road network. Research method used was to analyse the performance of a road section using the Manual of Road Capacity in Indonesia (MKJI 1997). Results of traffic flow measurements showed a consistent pattern: the highest vehicle volumes occurred on Saturday with peaks of 95.7 smp/h on Jl. Daud Dariyah (13.15-13.30) and 92 smp/h on Jl. Chik Ali Akbar (17.45-18.00). Meanwhile, Jl. Blang Pulo recorded a steady flow of over 1750 smp/hr with a DS of 0.77 (morning) and a peak of 1940.4 smp/hr (afternoon). Temporal analysis reveals a distinctive pattern where morning activity (07.00-09.00) is dominated by goods transport vehicles, while afternoons (16.00-18.00) are packed with shoppers using motorbikes. Road level of service classifications varied: from the worst condition on Jl. Daud Dariyah (level D-E) to the best on Jl. Melati (level B-C) with an average vehicle speed of 35.67 km/hour. The findings indicate an imbalance between road capacity (2299 smp/h) and traffic volumes, especially in segments adjacent to the market loading and unloading area. The comprehensive solution proposed includes management strategies for the short, medium and long term.]]>

<![CDATA[This study examines the comparison of labor productivity during normal working hours and overtime in the ceramic installation work of the Transit Office renovation project of the Ministry of Finance in Balikpapan City.The main issue is how the value of labor productivity differs between normal working hours and overtime, and its impact on the decline in productivity and the increase in wage costs.The research method was conducted through direct observation in the field over 10 days during normal working hours (08:00–16:00) and overtime hours (19:00–22:00), focusing on the productivity of ceramic workers using 60cmx60cm ceramic tiles.The research results show a significant difference in labor productivity between normal working hours and overtime, where productivity during overtime decreases due to fatigue, which also leads to an increase in labor wage costs.In conclusion, although overtime can accelerate project completion in the short term, the implementation of overtime hours in the long term negatively impacts productivity and cost efficiency. Therefore, proper management of overtime hours is necessary to maintain a balance between time, cost, and quality in construction projects.]]>

<![CDATA[The Rodalink showroom is an existing four-story building constructed of reinforced concrete. To compare the different material requirements, a construction study of this building was conducted using a steel structure based on SNI 1729:2020. First, the steel structure was modeled using AutoCAD, then the structural analysis was carried out with the ETABS program. The steel structure consists of main beam elements namely WF 350.175.6.9, WF 350.175.7.11, WF 350.250.9.14, and WF 350.250.8.12. For the sub-beams, the optimal profile is WF 300.200.8.12, while for the column profile is WF 400.300.10.16, and for the X-bracing component is WF 300.200.8.12. The material cost comparison shows that the steel structure portal is 95.45% more expensive with a total cost of IDR 826,467,401 compared to the concrete structure portal of IDR 422,863,490. The high cost of steel structure materials is due to the high cost of production and raw materials, complex manufacturing processes, and additional protection required to prevent corrosion. The price does not include labor costs. Concrete construction takes longer than steel construction, so the potential labor costs for concrete structures tend to be higher.]]>

<![CDATA[Development in coastal areas has a problem, namely concrete construction will come into direct contact with seawater. Seawater is one of the causes of failure in building structures. Innovations in the field of concrete material technology, one of which is to improve the properties of concrete, including the addition of certain materials, namely admixtures or additives to the concrete mixture, one of which is supperplaticizer. In this study, the compressive strength value of concrete immersed in 3 curing media will be compared, namely normal water, seawater in laboratory conditions and seawater directly. Based on the results of compressive strength, it shows that concrete that is directly exposed to seawater will experience a decrease in compressive strength. And after added the concrete supperplaticizer experiences an increase in the compressive strength value, this is in accordance with the supperplacizier properties which accelerate the hardening of the concrete and increase the sealability or density of the concrete. However, at compositions above 1% concrete, the compressive strength value has decreased.]]>

<![CDATA[Genetic algorithms are used to determine the best duration for each activity in the project so as to produce the optimum duration, namely the project duration that produces the minimum total project cost. This study determine the optimum project duration and the minimum Total Project Cost in the Faculty of Health Sciences Building Construction project, Brawijaya University. Secondary data were obtained from PT Citra Mandiri Cipta as the contractor. The initial population is formed from 16 chromosomes, each chromosome contains 57 genes, each gene contains data on the duration of each activity obtained randomly. Each chromosome provides information about the duration and total cost of the project using the PDM calculation. The relationship between fitness and total project cost is that the lower the total project cost, the greater the fitness value. To produce a better fitness value, crossover and mutation are carried out in each cycle (generation). After 500 generations of repetition, the optimum duration was obtained at 238 days and the total project cost was Rp 36,653,132,882.00, resulting in cost savings of Rp22,397,054 and a duration acceleration of 7 days. The total project cost and optimum duration with the Time Cost Trade Off calculation gave the same results.]]>
