Evaluasi Critical Success Factors terhadap Keberhasilan Proyek Konstruksi menggunakan Metode Analytical Hierarchy Process (Studi Kasus: Proyek Gedung IME UNSOED)
type: item
description: Construction building projects play an important role in supporting infrastructure development; however, their implementation often faces delays, cost overruns, and quality deterioration. Therefore, a comprehensive evaluation of the factors influencing project success is required. Critical Success Factors (CSFs) are key factors conditions, characteristics, or variables that directly affect a project’s success because they determine what must be managed effectively to achieve project objectives. This study was conducted through interviews and questionnaire surveys administered to project stakeholders. The data were analyzed using the Analytical Hierarchy Process (AHP) to obtain priority weights for each aspect and factor. The results identify seven aspects and twenty-three factors that influence the success of the Integrated Medical Education (IME) Building Project at UNSOED. The quality aspect has the highest priority, with a weight of 0.192. The five most dominant factors are the effectiveness of schedule control and monitoring (0.0744), early risk identification (0.0684), the quality control system and quality documentation (0.0681), compliance with technical quality standards (0.0644), and the level of user satisfaction (0.0593). These findings indicate that the dominant factors should receive primary attention in project management particularly those related to quality, time, and risk management in order to improve overall project success.

Analisis Model Tarikan Perjalanan pada Kawasan Perdagangan Kota Purbalingga (Studi Kasus: Pasar Bobotsari Purbalingga)
type: item
description: Trip generatioan is a concept in transportation planning that explains the relationship between economic activity in an area and the traffic movements it generates. This concept is essential for understanding how market activities influence community mobility and transportation infrastructure needs. Travel, in this context, is defined as the movement of individuals from an origin to a destination to conduct various activities. This study aims to analyze the characteristics of people’s travel behavior to shopping areas and identify the factors that influence travel attraction to those areas. Data were collected through questionnaires distributed at Bobotsari Market in Purbalingga, involving a population of 11,125 people and a sample of 320 respondents. The analysis employed linear regression and correlation coefficient analysis using SPSS software. Based on the results, the model of travel attraction to the Bobotsari Market shopping area is represented by the equation: Y = 1.408 – 0.207(X3) + 0.231(X4) – 0.028(X10), where X3 refers to building floor area, X4 to parking area, and X10 to the price of goods. The characteristics of travelers show that most respondents have 3–4 family members and predominantly use private motorcycles. Motorcycle use is strongly associated with limited parking space, crowded market conditions, travel distances of 2–4.9 km, travel times of 6–10 minutes, and low transportation costs. Most travelers are women aged 21–40 years, originating from the Bobotsari area. The regression results indicate that the building floor area (X3) with sig. 0.023 < 0.05, parking area (X4) with sig. 0.009 < 0.05, and price of goods (X10) with sig. 0.013 < 0.05 significantly influence travel attraction (Y). These findings confirm that larger building space, adequate parking, and affordable goods play key roles in attracting visitors. Several recommendations can be proposed to manage trip attraction to the market, including integrating transportation and land-use p…

Beton Ramah Lingkungan menggunakan Serat Serabut Kelapa sebagai Bahan Tambah Campuran Beton
type: item
description: Concrete is the main construction material widely used throughout the world. The development of concrete technology demands better performance, both in terms of mix composition and the addition of additives to enhance concrete strength. This has led to the idea of finding additive materials that can improve concrete strength, one of which is by using coconut fiber as an additional material. This study aims to determine the compressive strength, flexural strength, and split tensile strength of concrete with the addition of coconut fiber at proportions of 0%, 0.7%, and 1.5% of the specimen weight. The study used a water–cement ratio (w/c) of 0.52, and the tests were conducted at the ages of 7 and 28 days. The research methodology used was experimental, with 18 cylindrical and 9 beam specimens. The average compressive strength test results at 12 days for concrete with 0%, 0.7%, and 1.5% coconut fiber additions were 21.27 MPa, 13.10 MPa, and 8.54 MPa, respectively. The estimated 28-day compressive strength results were 25.4 MPa for 0%, 16.2 MPa for 0.7%, and 10.6 MPa for 1.5% fiber content. The average split tensile strength results at 12 days for 0%, 0.7%, and 1.5% fiber content were 0.98 MPa, 1.15 MPa, and 0.75 MPa, respectively. The estimated 28-day split tensile strengths were 1.16 MPa, 1.43 MPa, and 0.92 MPa, respectively. The average flexural strength test results at 7 and 28 days for 0%, 0.7%, and 1.5% coconut fiber additions were 4.62 MPa, 3.16 MPa, and 2.94 MPa, respectively.

description: Juana River has a watershed area of ​​1,374.61 km2 stretching 67.26 km across Kudus Regency and Pati Regency, Juana River plays a vital role in Pati Regency and its surroundings. However, this river often faces flooding problems, especially when there is an increase in water discharge from the Wilalung Dam. This condition is exacerbated by sedimentation factors, narrowing, and changes in land use along the river flow. This study aims to analyze the maximum capacity of the Juana River in overcoming flooding when the Wilalung Dam water discharge increases. The research methods used include collecting secondary data in the form of rainfall data, topographic data and morphology of the Juana River, the data was obtained through BBWS Pemali Juana and other related agencies. These data are then processed and analyzed using HEC-RAS 6.1 to model river water flow and predict maximum capacity. The results of the hydrological analysis using the Nakayasu HSS method, the planned flood discharge with a 50-year return period of Q = 545 m3/s The river capacity was simulated by dividing the flow discharge to the Juana River by 50 % to 290 m3/s, Hydraulic analysis using HEC-RAS 6.1 software, the simulation results showed that there was still overflow on the existing and planned cross-sections, but the overflow on the planned cross-section was relatively reduced by 28.19 %. To overcome the overflow in the upstream section, a change in the cross-section design was planned with a base width of 30 m, a top width of 38 and a depth of 7 m. Land use arrangements to build flood control dams or carry out river diversion planning schemes used to slow down the flood arrival time and reduce the magnitude of the flood discharge.

Evaluasi Tingkat Pelayanan Simpang pada Persimpangan Jalan Raya Mranggen dan Jalan Raya Kauman
type: item
description: Transportation forms the foundation of economic development. Advances in transportation are crucial for supporting economic activities and accelerating both regional and national development. As economic activity increases, the demand for mobility also rises. To meet this growing demand, the number of motorcycles in Indonesia has increased by 5.95%. This growth has contributed to traffic congestion, particularly at intersections, which are convergence points for various traffic flows. According to data from Statistics Indonesia (BPS), Central Java Province ranks third in terms of the highest number of motorized vehicles, with Demak Regency being one of the areas most affected. One intersection in Demak Regency that frequently experiences traffic congestion is the intersection of Jalan Raya Mranggen and Jalan Raya Kauman. This condition disrupts community mobility and increases the risk of traffic accidents. Therefore, the purpose of this study is to analyze the intersection capacity, degree of saturation, and level of service in order to optimize traffic flow performance. The traffic performance at the intersection of Jalan Raya Mranggen and Jalan Raya Kauman can be evaluated by analyzing the level of service (LOS) at the intersection. This evaluation refers to the Indonesian Highway Capacity Guidelines (PKJI) 2023, which provides results in the form of intersection capacity, degree of saturation, delay, and level of service. The method used in this research involves direct observation and data collection at the study site. Based on the evaluation results, the intersection of Jalan Raya Mranggen and Jalan Raya Kauman has a capacity (C) of 2,952 PCU/hour, with a total traffic volume of 3,637 PCU/hour, resulting in a degree of saturation of 1.23 and a delay value of 50.57 seconds/PCU. The conclusion drawn from this study is that the level of service (LOS), as indicated by the delay value of 50.57 seconds/PCU, falls under level E. This signifies a poor level of service…

Analisis Tingkat Kerusakan Jalan Raya menggunakan Metode Bina Marga dan Surface Distress Index (SDI) (Studi Kasus: Jalan Lingkar Timur Kudus)
type: item
description: Roads are vital infrastructure in the land transportation system, playing a crucial role in supporting public mobility and the smooth distribution of goods and services. Good road quality is an important indicator of economic growth, regional connectivity, and equitable national development. However, over time and with high traffic intensity, road pavement conditions tend to gradually degrade. Factors such as extreme weather, poor drainage, low-quality materials, and non-compliance with technical specifications during construction and maintenance processes contribute to accelerating structural and functional damage. One of the affected road sections is the Kudus East Ring Road, which plays a strategic role in connecting industrial areas, residential areas, public facilities, and economic centers in Kudus Regency and its surroundings. This study aims to analyze the level of pavement damage on this section and determine its priority for treatment using two approaches: the Bina Marga method and the Surface Distress Index (SDI). The Bina Marga method classifies road conditions based on visual observation of the type and severity of damage, then determines the Priority Order (UP) as a reference in providing recommendations for periodic and routine maintenance actions. Meanwhile, the SDI method uses a quantitative approach by considering parameters such as the percentage of crack area, crack depth, and the number of holes, and the depth of wheel grooves, which are converted into an SDI score. Comparison of research results shows that the level of damage to the Kudus East Ring Road at STA 1+800 to 3+800 with the Bina Marga method is mostly categorized as light to moderate damage with UP 4-6, while the results of research with the SDI method at STA 1+800 to 3+800 show that the level of damage is mostly categorized as good with an SDI value of 15. This discrepancy reflects the differences in approach and sensitivity between the two methods in assessing road damage.

Analisis Sumur Resapan dalam Mengatasi Banjir di Perumahan Punden Arum Desa Kedunguter Kecamatan Karangtengah Kabupaten Demak
type: item
description: Flooding caused by high-intensity rainfall is a common issue in the Punden Arum residential area, located in Kedunguter Village, Karangtengah District, Demak Regency. This problem has prompted the search for effective solutions to reduce the risk of flooding in the area. This study aims to analyze the effectiveness of infiltration wells (resapan wells) in mitigating floods. The analytical methods used include field surveys, hydrological analysis, and infiltration well capacity analysis. The study is based on local rainfall parameters and appropriate design considerations. The hydrological analysis showed that the runoff discharge for a Type 45 house with an area of 846 m² is 0.85 m³/second for a 2-year return period, 1.00 m³/second for a 5-year return period, and 1.07 m³/second for a 10-year return period. Meanwhile, the calculation of the area’s total runoff discharge, which includes both residential and road catchment areas with a total area of 958 m², results in a discharge of 1.23 m³/second for the 10-year return period, based on the runoff coefficient (C) value. The planned infiltration wells are designed with a height of 2 meters and a radius of 0.5 meters (1-meter diameter), resulting in a total storage volume of 15.7 m³ and an infiltration discharge of 2.261 m³. In the study area, a total of 10 infiltration wells are planned, capable of accommodating a total rainwater runoff volume of 17.961 m³. The results of the infiltration well planning indicate that the design is effective in retaining rainwater runoff in the study area, as the total storage volume of the infiltration wells exceeds the required runoff volume.

Analisis Kinerja Simpang Bersinyal di Jl. Ahmad Yani Kota Semarang Menggunakan Alat Bantu Software VISSIM
type: item
description: The increase in traffic volume at the signalized intersection on Jalan Ahmad Yani Semarang City, causes congestion that has the potential to disrupt the smooth flow of traffic. The method used is to model the existing conditions of the intersection in VISSIM, then conduct simulations to obtain performance data such as traffic volume, degree of saturation, waiting time, and vehicle delay. The results of the study indicate that high traffic volume and suboptimal traffic light cycles cause vehicle deceleration at red lights and acceleration at green lights, resulting in congestion and congestion. The current simulation shows an average queue length of 127.63 meters with a maximum queue length of 227.20 meters, and an average vehicle delay of 99.69 seconds, which is categorized as Level of Service (LOS_F), indicating very poor traffic conditions. In reducing the very bad LOS, then for next 5 years it is necessary to have recommendations that can improve traffic flow such as diverting one-way traffic flow on the arms of Jl.

Komparasi Tingkat Kerusakan Jalan antara Metode PCI dan Bina Marga (Studi Kasus: Jalan Raya Demak-Kudus, Gajah, Kabupaten Demak)
type: item
description: Roads are a vital element of infrastructure that support public mobility and drive economic growth. Road damage can disrupt traffic flow, increase vehicle maintenance costs, and potentially cause accidents. In Demak Regency, particularly on the Demak-Kudus Highway in Gajah District, road damage has become a major challenge in infrastructure maintenance.This study compares two methods of road condition assessment: the Pavement Condition Index ( (PCI)) and the Bina Marga method. PCI evaluates road conditions on a scale of 0-100, while the Bina Marga method uses the Priority Order (UP) system to determine repair needs. The research results indicate that PCI scores range from 50 (Fair) to 89 (Excellent), suggesting that most roads are still usable but require maintenance. The Bina Marga method produces an average UP score of 6.17 highlighting the need for periodic maintenance. Based on the comparison, the PCI method provides a more detailed assessment of road damage, whereas the Bina Marga method is more effective in prioritizing repairs. A combination of both methods can serve as an optimal solution for road maintenance planning.

Analisis Kinerja Simpang APILL dengan Metode PKJI 2023 (Studi Kasus: Simpang Majapahit Kota Semarang)
type: item
description: The queue length at signalized intersections (APILL) significantly affects traffic congestion and overall traffic efficiency. This study analyzes the queue length at the Majapahit Intersection in Semarang through field measurements and the application of the 2023 Indonesian Highway Capacity Manual (IHCM/PKJI 2023) to identify approaches exceeding threshold values and validate the results against applicable standards. The findings indicate that queue lengths range from 71.72 m to 187.72 m, with the longest queue observed on the Gajah Raya Road approach (Degree of Saturation, DS = 1.15), surpassing the acceptable limit of 0.85. In contrast, the Brigjen Sudiarto Road and Majapahit Road approaches remain within safe operational thresholds. Validation results highlight the need for increased capacity and improved traffic management to reduce queue lengths. To enhance intersection performance, the study recommends improvements in road geometry, signal phase adjustments, and the implementation of more effective traffic management strategies aimed at minimizing queuing, reducing delays, and improving traffic flow.

Perancangan Ulang Guest House 6 Lantai Semarang
type: item
description: Alongside Indonesia's ever-accelerating development. A secure and cozy place to live is one of the infrastructure and supporting services. Planning for multi-story buildings housing apartments is not equivalent to planning for single-story structures. To enable the intended building to be constructed in compliance with technical principles that are both affordable and safe to use, building planning is required to ascertain the necessary dimensions and amount of reinforcement. Structures that require special planning are those that pose a significant risk because of various elements, including the building's purpose, the type of structure it uses, and its location—whether or not it is in an earthquake-prone area. This project was planned with the advancement of civil engineering and the passage of time in mind, taking into account architectural considerations.The project's functional stability, affordability and ease of execution, the structure's capacity to handle the building system, and the surrounding environmental factors as a new home or dwelling in the city of Semarang. If a structure is prone to being noticeably tipped, shifted, or flipped during the course of the intended building, structural planning is vital to ensure that the structure is considered stable. Structural planning must adhere to the government's regulations.

Analisa Kapasitas Sungai Rawalumbu terhadap Banjir pada Daerah Aliran Sungai (DAS) Rawalumbu
type: item
description: The Rawalumbu River is located in Rawalumbu District, Bekasi City. High population density, limited land, and poor drainage conditions have reduced water absorption areas, leading to erosion and an increased risk of flooding. This study aims to determine the design discharge and river dimensions required to prevent flooding. Hydrological analysis of planned rainfall was conducted using the Normal, Gumbel Type I, Log Pearson III, and Log Normal methods. The design flood discharge was calculated using the Nakayasu and Snyder Unit Hydrograph methods, while hydraulic analysis was conducted using the HEC-RAS application. Simulation results indicate that flooding occurs under existing conditions but not with the proposed design. It is necessary to increase river dimensions and levee elevation to accommodate larger discharge volumes. Each river section has different cross-sectional dimensions, with the main river featuring a base width of 20 meters, a height of 4 meters, and varying elevations at the upstream and downstream ends. The tributary has smaller dimensions, with a base width of 15 meters and a height of 4 meters. The Rawalumbu River is designed to accommodate a 25-year return period discharge of 81.24 m³/s, with the expectation that it will effectively prevent flooding.

Perencanaan Ulang Jembatan Glapan Timur Kabupaten Grobogan Girder 40 Meter
type: item
description: East Glapan Bridge, Grobogan Regency is an alternative bridge that connects Gubug with Kedungjati, and Grobogan with Semarang City. Because the bridge building is quite old, it needs to be replaced with a new bridge that can function as an alternative route forward. In addition, several years ago, frequent flooding in the river basin had resulted in instability in the nine bridge pillars. In this research, the author used the superstructure of the bridge using prestressed concrete beams and the working load method, where the I girder was chosen as the main structural element. Bridge planning is carried out through manual structural analysis assisted by MS Excel software, with reference to SNI-1725-2016 which explains Loading for Bridges, apart from that also SNI-2833-2016 which discusses Bridge Planning against Earthquake Loads, as well as the latest PKJI (Indonesian Road Capacity Guidelines) from 2023, as well as relevant regulations regarding bridge planning. The results of the planning for the East Bridge, Grobogan Regency from the analysis of calculations that have been carried out, obtained 2 pillars and 2 types of girders with dimensions of 1,7 m and 2,1 m. The research results show that the bridge is declared safe and suitable for use, because the capacity value obtained from the calculation analysis exceeds the permit capacity value. Control of 2-way overturning, control of 2-way shear, control of lateral bearing capacity, control of 2-way axial bearing capacity, and control of the allowable bearing capacity of drilled piles showed good results. This analysis concludes that the condition of the planned bridge structure is safe to accept the combination of loads and ultimate loads.

type: item
description: Workplace accidents are occurrences that have an impact on workers who carry out construction activities. The level of risk that has an effect ranges from low to severe risk in every workplace accident in construction activities. Data collection was carried out on the implementation of the K3 program in the construction project of the STIE II Semarang campus. Data were obtained by distributing questionnaires to both workers and development implementers. Furthermore, the results of the analysis can be used to evaluate the implementation of the Occupational Health and Safety (OHS) program to minimize workplace accidents that may occur in the construction process. The research method used is to determine the ranking of each item of the assessment of the implementation of the OHS program which is then analyzed by the Mean value. Based on the results of the analysis, it was found that the obstacle that became an inhibiting factor in implementing the OHS program in his construction process was the minimum paradigm of workers regarding occupational safety and health. The workers consider that Personal Protective Equipment (PPE) is not a basic need at work. The workers feel uncomfortable using PPE when they are at the construction site. In addition, workers are used to working as is without self-protection.

Rekayasa Lalu Lintas Jalan Tirto Agung akibat Aktivitas Antar Jemput Sekolah Al Azhar menggunakan Program VISSIM
type: item
description: Traffic congestion in urban areas has been a major issue for years, considering that the transportation demand cycle does not always allow for resolving congestion through road capacity expansion. Congestion caused by daily activities, such as the Al Azhar school pickup and drop-off, results in vehicle queues on Tirto Agung Street in Banyumanik. Therefore, it is necessary to analyze and apply traffic engineering strategies to improve intersection performance. Performance analysis of the intersection was conducted using PKJI 2023, and existing intersection conditions were modeled using VISSIM (Student Version) software. Based on the analysis using PKJI 2023, the existing intersection showed a degree of saturation (DJ) of 0.62, capacity (C) of 2776.48 vehicles/hour, intersection delay (T) of 11.32 seconds/vehicle, and queue probability (Pa) of 16%-34%, with a level of service index (ITP) of C (Sufficient). According to the VISSIM (Student Version) analysis, with the addition of traffic signals, the results showed a vehicle delay (VehDelay) of 8.50 seconds/vehicle, a queue length (Qlen) of 11.91 meters, and a level of service (LOS) of B (Good). Therefore, the traffic engineering recommendation for the Tirto Agung, Estetika Raya, and Klentengsari intersections is to implement a signalized intersection with a cycle time of 49 seconds.

Evaluasi Tingkat Pelayanan Simpang Fatmawati, Kota Semarang
type: item
description: Transportation is a means to support human activities and is also one of the pillars of economic growth. Economic growth also has an impact on population growth. Population growth affects the performance of traffic that occurs. The high traffic flow at Simpang Fatmawati occurs at each approach to the intersection, namely the approach from Brigjen Soediarto Street, the approach from Fatmawati Street, and the approach due Majapahit Street. The traffic performance at Simpang Fatmawati able to assess by reviewing the (LOS) or level of service that occurs. The assessment of the performance of Simpang Fatmawati can be done using the Indonesian Road Capacity Guidelines (2023) method, with results such as intersection capacity, degree of saturation, queue length, number of stopped vehicles, and delays that occur. Furthermore, based on the degree of saturation results, the Level of Service (LOS) of Simpang Fatmawati can be determined. Referring to the analysis results, at the approach from Brigjen Soediarto Street, the queue length is 284 meters. At the approach from Fatmawati Street, the queue length is 272 meters. While at the approach from Majapahit Street, it is 425 meters. At the approach from Brigjen Soediarto Street, the Degree of Saturation (DS) value is 1.09. At the approach from Fatmawati Street, a value of 1.32 is obtained. Meanwhile, at the approach from Majapahit Street, the Degree of Saturation (DS) reaches a value of 2.3. Based on the Degree of Saturation (DS) value and the queue length, the Level of Service of Simpang Fatmawati can also be determined to be at level (F).
