Nuhjtst@untan.ac.id<p>Project performance is greatly influenced by labor productivity. The productivity of each worker is different and is influenced by several factors such as work experience, age, education level, wages, site conditions, weather, coordination and planning, and leadership skills. This study examines the value and level of labor productivity, the variables that influence productivity, and the efforts to improve labor productivity. Observations in this study were conducted using the construction sampling method to observe the work scope, construction time, number of workers, adequate time, contribution time, ineffective time of lightweight steel-roof frame construction work, and direct on-site observation. Next, the level of labor productivity must be analyzed using the Labor Utilization Rate (LUR) approach. The analysis shows that the average productivity values for horse labor were 2,581 m²/OH for ironworkers and 5,197 m²/OH for manual workers. The productivity value for ironworkers in lath construction is 5,256 m²/OH. From the analysis of the average level of labor productivity (results are more than 50% of her), it can be concluded that the level of labor productivity in the construction project of the catholic church of St. Maria Bunda Pengharapan Bunut Sanggau is satisfactory. The most significant variables affecting labor productivity are control variables. As a result of interviews with stakeholders, it was found that ways to increase labor productivity include effectively using time, creating a working system that is easy to work in, ensuring that workers have specialized knowledge, and ensuring thorough on-site supervision. Improvements are needed to create a good working environment.</p>2024-03-24T16:26:19+00:00Copyright (c) 2024 Jurnal Teknik Sipilhttps://jurnal.untan.ac.id/index.php/jtsuntan/article/view/75946PERFORMANCE ANALYSIS OF TUGU PANCASILA ROUNDABOUT IN PUTUSSIBAU CITY KAPUAS HULU DISTRICT2024-03-24T16:26:38+00:00Hifzhan Hanif Darmawanhanifdarmawan511@gmail.comElsa Tri Muktijtst@untan.ac.idS. Nurlaily Kadarinijtst@untan.ac.idTugu Pancasila Roundabout in Putussibau City is a 5-arm roundabout that organizes traffic in 5 directions of movement. Poor traffic management at this roundabout, such as the lack of roundabout signs and no separation island or median on roads other than the main road, makes motorists who should pass through the roundabout instead choose not to cross the roundabout and go against the flow because they want to reach their destination faster. In addition, due to the increasing population and the volume of vehicles traveling, it is anticipated that in the future, the Tugu Pancasila roundabout will have increasingly heavy traffic flows. The performance analysis of Tugu Pancasila Roundabout was calculated using MKJI 1997 and VISSIM software. The performance analysis of Tugu Pancasila Roundabout was carried out by taking roundabout geometric data, manually taking side obstacle data, and traffic volume data for three days using survey aids in the form of CCTV starting at 06.00 - 18.00 WIB. Analysis of the existing conditions in 2023, the highest degree of saturation is 0.62 with the level of service B; in the 2028 projection conditions, the highest degree of saturation is 0.73 with the level of service B; and in the 2033 projection conditions, the highest degree of saturation is 0.86 with the level of service E. With a poor level of service, the volume of vehicles and the roundabout capacity could be more balanced, so improvements are needed for the Tugu Pancasila Roundabout in Putussibau City. The improvement solution is to re-plan the roundabout following the Roundabout Planning Guidelines for Intersections (2004). For the results of the MKJI 1997 analysis of the roundabout re-planning solution, the 2028 projection obtained the highest degree of saturation of 0.54 with level of service B, and in the 2033 projection obtained the highest degree of saturation of 0.63 with level of service B. for the results of the VISSIM software simulation, the roundabout re-planning solution for the 2028 projection obtained a delay of 13.14 seconds with level of service B, and the 2033 projection obtained a delay of 15.60 seconds with level of service C.2024-03-17T08:33:24+00:00Copyright (c) 2024 Jurnal Teknik Sipilhttps://jurnal.untan.ac.id/index.php/jtsuntan/article/view/75575APPLICATION OF THE VISSIM PROGRAM IN EVALUATION AND IMPROVING THE PERFORMANCE OF UNSIGNALED INTERSECTIONS IN PONTIANAK CITY2024-03-24T16:26:38+00:00Elsa Tri Muktielsatrimukti@civil.untan.ac.idIrwandi Irwandiirwandih105@gmail.comM.Dzulfikar Andika Satriatamaelsatrimukti@civil.untan.ac.id<p>As part of transportation infrastructure, road infrastructure is essential in increasing community mobility and accessibility. When traffic volume increases or changes its characteristics, the intersection is the first thing that shows the inability to serve the increased traffic. Because intersections are critical points of the traffic system where vehicles from different directions meet, obstacles and traffic jams at intersections will affect the capacity of the road concerned, so the level of service at the intersection will decrease, including the speed, safety, and comfort of road users.</p><p>This research aims to evaluate the performance of the third and fourth unsignaled intersections in Pontianak City (with a case study of the intersection of Jl. Sultan Abdurrahman-Jl. Sulawesi and the intersection of Jl. Alianyang-Jl. Putri Dara Nante-Jl.

This increase in land demand can cause land use changes, affecting the runoff coefficient. Based on the reasons above, research was conducted to determine the effect of changes in land use on the magnitude of the runoff coefficient in the upstream part of the Kapuas River Basin from 2012 to 2017 and 2017 to 2022.</p><p>The runoff coefficient calculation uses the U.S. Forest Service, Hassing, Kodoatie, and Syarief methods. Each method uses different parameters to determine the results. Data processing is carried out using a Geographic Information System (GIS).</p><p>The analysis and calculations show that the runoff coefficient values obtained in the Upper Kapuas River Basin using the U.S. Forest Service method in 2012, 2017, and 2022 are 0,133, 0,136, and 0,145. The Hassing method results are 0,308, 0,309, and 0,312, and the Kodoatie and Syarief method results are 0,156, 0,167, and 0,173. This value shows that the Upper Kapuas River Basin is in reasonably good condition because the runoff coefficient value is far below 1.</p>2024-03-17T07:21:15+00:00Copyright (c) 2024 Jurnal Teknik Sipilhttps://jurnal.untan.ac.id/index.php/jtsuntan/article/view/73031MAPPING OF FLOOD-PRONE AREA UNDER IMPACT OF TIDAL INFLUENCE IN SINGKAWANG CITY2024-03-24T16:26:38+00:00Arif Senoajiarif.senoaji@student.untan.ac.idS.B. Soeryamassoekabenzsoerya72@gmail.comDanang Gunartojtst@untan.ac.id<p>Flood is a seasonal threat that occurs when a body of water overflows from the existing channel and inundates the surrounding area. In the last three years, Singkawang City has experienced frequent floods. Although they did not cause casualties, the floods caused much harm to the surrounding community, such as educational and office activities that could not run normally. To reduce the impact of the flood disaster in Singkawang City, a complete and integrated flood control and management effort is needed, which maps flood-prone areas in its initial stage. This research aims to provide information about the characteristics of the tides and the level of vulnerability to flooding caused by the influence of the tides in Singkawang City in the form of a zoning map.</p><p>In this research, the parameters used are the distance from the beach, river buffer, land slope, land elevation, and land cover. Then, flood-prone areas can be mapped using Geographic Information Systems (GIS) and the weight overlay method.</p><p>This research shows that in Singkawang City, the area considered safe from flooding is 24048.449 Ha or 43.947%. Areas classified as not vulnerable have an area of 19938.498 Ha or 36.436%. Areas classified as vulnerable have an area of 9068.206 Ha or 16.571%.

This study took the location of the Klakah Rejo-Benowo road section, Surabaya City—data analysis by calculating the Deduct Value, m, TDV, CDV, and PCI. The research results state it was concluded that five types of damage occurred in Jalan Klakah Rejo-Benowo, Surabaya City. The types of damage are Grooves, Patches, Alligator Cracks, Weathering and Loose Granules, and Pits. Damage caused by high rainfall conditions (> 900mm/year) & Daily Traffic Volume exceeds the provisions of the Binamarga. After analysis, it shows that the road pavement is in Moderate/Fair condition; field analysis results and values calculated using the PCI (Pavement Index Condition) method for damaged road conditions can provide recommendations for road repairs using the Asphalt Institute MS-17 method, namely patching and resurfacing. Based on the analysis of the road condition values obtained, the solution must be patched and re-coated so that water does not quickly seep into the road layer, which causes more severe road damage.</span>2024-02-28T15:58:00+00:00Copyright (c) 2023 Jurnal TEKNIK-SIPILhttps://jurnal.untan.ac.id/index.php/jtsuntan/article/view/67120CHARACTERISTICS OF TRAFFIC ACCIDENTS ON 4/2D ROAD TYPES ON THE SURABAYA - MOJOKERTO TOLL ROAD ( CASE STUDY: WARUGUNG - PENOMPO TOLL ROAD SECTION)2024-02-28T15:58:17+00:00Achmad Ipung Dwi LaksonoLaksonoipung46@gmail.comHary MoetrionoLaksonoipung46@gmail.com<span lang="EN-ID">In developing road infrastructure, keeping pace with the transportation sector and the rapidly growing economy is vital. Inadequate road infrastructure conditions will cause problems on the road, namely traffic accidents and congestion, which results in a lack of driver comfort. PT Jasa Marga can undoubtedly find out the leading cause of the accident. This study aimed to determine the characteristics of traffic accidents on the 4/2d road type, precisely on the Surabaya - Mojokerto toll road on the Warugunung - Penompo toll road. The Surabaya–Mojokerto Toll Road or Sumo Toll Road is a 36.27-kilometer-long toll road that connects the City of Surabaya with the City of Mojokerto, East Java Province. This toll road is connected to the Kertosono-Mojokerto Toll Road to the west. The class of vehicles on this toll road, such as trucks and large-laden cars, can also be said to be one of the characteristics of traffic accidents. Location of accident-prone points (BlackSpot) on the Warugunung – Penompo toll road in 2021 on line A, namely at Km 3+000 – 4+000 of the Warugunung – Driyorejo section, because at that location there are road slopes and bends, so many motorists drive at high speed high and have to slow down when there is a descent and many riders do not anticipate it.

The distribution of clean water from regional companies tends to be less than optimal, and there is high rainwater runoff, causing the channel discharge to increase along with the growth of land converted into residential and business areas. Therefore, houses often use fresh water storage, both raw and rainwater, to meet clean water needs. One type that is often used is concrete culverts. However, concrete culverts have gaps in the joints that have the potential to contaminate storage water. The development of modular wells can be an option that is superior in various aspects to concrete culverts. The results showed that installing polypropylene modular wells costs less than concrete culvert wells. In addition, the use of modular wells also has advantages in terms of ease of installation and maintenance, as well as efficiency in land use. Endurance strength Modular wells can carry a load of up to 24 tons/m2. Thus, the results of this study are expected to provide alternative methods of storing clean water in Pontianak City that are more effective and efficient in terms of cost and quality by considering technical and environmental factors.</span>2024-02-06T14:19:06+00:00Copyright (c) 2023 Jurnal Teknik Sipil Universitas Tanjungpura (JTST)
