Abstract

This study aims to analyze the impact of parking on the roadway on the performance of one-way streets, using the case study of Cengkeh Street in Masohi City District. Parking on the roadway is one of the factors contributing to the decline in road performance, especially on road segments that connect to economic activities, such as shopping centers and markets. The issues raised include reduced road capacity, decreased vehicle speed, and increased saturation degree due to parking on the roadway. The methodology used in this study involves a quantitative approach, collecting primary data through direct surveys and analysis using the Indonesian Road Capacity Manual (MKJI) 1997. The results show that the highest average daily traffic occurs on Sundays with 539 vehicles per hour. Parking on the roadway significantly affects road performance. Traffic volume increases when parking appears on the road, while road capacity decreases from normal conditions. The road capacity with parking on the road is 1,253.26 passenger car units per hour and 2,610.96 passenger car units per hour without parking on the road. The degree of saturation also significantly increases, reaching 0.43 in conditions with parking, with road service level up to level B, approaching the maximum road capacity limit. Parking characteristics show that the highest parking volume occurs on Tuesday from 10:00 AM to 12:00 PM WIT, with a high accumulation of vehicles on both sides of the road. This study provides recommendations for rearranging the parking system, implementing parking bans in certain zones, and optimizing parking spaces off the road to improve traffic performance. Keywords: Parking, performance, capacity, degree of saturation, level of road service

Abstract

The foundation of a substructure serves as the desired bearing capacity in a pile, which must be able to provide adequate support for the loads acting upon it. The foundation of the Religious Court building in Seram Bagian Barat Regency experienced discrepancies during the pile-driving process, which deviated from the initial plan. This raises the question of whether the pile foundation, with its bearing capacity, can adequately support the acting loads. The aim of this study is to determine the bearing capacity and settlement of the pile foundation of the Religious Court building in Seram Bagian Barat Regency using the Schertmann and Nottingham method, as well as the Meyerhof method, based on cone penetration test (CPT) data. This research showed that the calculated ultimate bearing capacity of a single pile, derived from the CPT data using the Schertmann and Nottingham method, was 34.3601 kN, while the Meyerhof method yielded a value of 202.58 kN. This indicated that the Schertmann and Nottingham method provided the highest bearing capacity, while the Meyerhof method resulted in the lowest. The calculation of pile foundation settlement for a group of three piles indicated a single settlement of 0.03 m and a group settlement of 0.06 m.

Abstract

Building Information Modelling (BIM) is one of the significant technological and communication advancements in the construction services industry. BIM represents one of the most promising developments in the construction sector. Using BIM technology, a virtual model of a building, known as a building information model, can be digitally constructed and used for planning, design, construction, and maintenance. According to the Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia No. 22/PRT/M/2018 concerning the Construction of State Buildings, the application of BIM is mandatory for non-simple Stateok buildings with an area exceeding 2000 m² and more than two floors. Based on this regulation, this study aims to evaluate the factors influencing the implementation of BIM among construction project stakeholders in Ambon City, Indonesia. Data for this research were collected through a survey, including questionnaires and interviews with respondents in the construction industry. The analysis employed descriptive statistical methods, including Central Tendency Measurement, Variability Measurement, and Relative Importance Index (RII). The results indicate that the main factor affecting the implementation of BIM in construction projects in Ambon City is the lack of BIM education or training.

Abstract

In the implementation of electric power distribution, various issues are frequently encountered. The distribution of electric energy through the distribution network often faces problems such as voltage drops. Power delivery through the distribution network to the load is prone to several challenges, particularly voltage drop. The Makariki feeder is classified as a relatively long radial feeder, with a total line length from the ULPL Masohi substation to the terminal point in Beben, Moti, measuring 63.37 km. Therefore, an analysis is needed to determine the voltage profile both before and after the use of a capacitor bank on the Makariki feeder distribution network. The longer the distribution line, the greater the voltage drop it experiences. The single-line diagram of the Makariki feeder was modeled in ETAP based on the obtained data. The simulation results showed that the voltage drop in the Makariki feeder under installed load conditions was 6.30%, under peak load conditions was 4.25%, and under off-peak load conditions was 3.25%. Based on these results, it can be seen that the voltage drop under installed load conditions exceeds the SPLN NO. 72 standard of 1987, which sets a maximum of 5%. After corrective measures using capacitor banks were applied to the installed load condition, voltage drops were reduced to 3.60% in scenario 1, 1.55% in scenario 2, and 2.85% in scenario 3. Among the three scenarios, all improvements showed a reduction in voltage drop on the Makariki feeder voltage profile under installed load conditions. However, the voltage drop percentages differed across scenarios. Scenario 2 demonstrated the most effective reduction in voltage drop among the three.

Abstract

This study aims to analyze and design the artificial lighting system of the Faculty of Engineering Building at Pattimura University, Ambon, to meet the standards specified in SNI 03-6575-2001. Measurements were carried out using a Lux Meter Kuber AS803 to obtain natural and artificial lighting data for each room across the building’s three floors. Primary data include room dimensions, lamp types and quantities, and existing conditions, while secondary data were obtained from literature and lighting standards. Analysis was conducted using DIALux Evo to determine the average illuminance level and assess compliance with SNI standards. The results show that most classrooms and lecturers’ rooms have lighting levels below the standard, with average illuminance values of 112,25 lux, whereas the minimum standard for classrooms is 250-350 lux. The low illumination levels are caused by limited lamp quantity and low lamp power. This study recommends adding more lighting points, increasing lamp wattage, and optimizing lighting layout through DIALux Evo simulation to meet the standard and improve visual comfort for users. Based on the analysis and planning results, the total cost required to meet the artificial lighting standard for the entire building is Rp 280,924,489.Keywords: Artificial lighting; Dialux evo; construction costs

Abstract

This research examines the application of the Cost Significant Model (CSM) for estimating costs in classroom rehabilitation projects at public schools in Maluku Province. Given the region’s challenging geographical characteristics and the urgent need to improve educational infrastructure, accurate and efficient cost estimation methods are essential to prevent budget overruns and delays. The study collects and analyzes historical budget data from similar projects implemented between 2019 and 2024. By identifying the most significant cost items that contributed to the largest share to total expenses, the CSM allows for targeted resource allocation and effective risk mitigation. The research employs quantitative methods, including inflation adjustments and multiple regression analysis, to develop a predictive cost estimation model. Model accuracy is assessed using the Mean Absolute Percentage Error (MAPE), which shows a low average error of just 2.26%, confirming CSM’s effectiveness and consistency with previous studies. The findings demonstrate that CSM is both efficient and reliable for early-stage cost estimation in educational facility rehabilitation, especially when detailed project information is limited. The study recommends integrating CSM with conventional methods for optimal results as project data availability improves.

Abstract

As a Public Service Agency, Pattimura University utilizes the potential of aquatic resources in the Inner Ambon Bay by using reinforced concrete fish cages. The construction of the Concrete Cage by BLU Pattimura University has not yet been supported by a financial feasibility study that could affect the business or investment outcomes, making it uncertain whether the project can achieve the required revenue targets to generate profit. This study aims to contribute by ensuring that the concrete cage project has the potential to become a profitable long-term investment through a review of its economic parameters. This serves as a reference in determining whether a project is feasible or not. The methods used include Net Present Value (NPV), Benefit Cost Ratio (BCR), Payback Period (PP), and Sensitivity Analysis. Based on the results of the sensitivity analysis, Scenario I shows an NPV value of Rp55,420,888, a BCR of 1.469086167, and a PBP of 3 years, 5 months, and 12 days. Scenario II has an NPV value of Rp76,200,487, a BCR of 1.644966103, and a PBP of 3 years, 1 month, and 1 day. Scenario III shows an NPV value of Rp87,811,946, a BCR of 1.743246279, and a PBP of 2 years, 10 months, and 26 days. Scenario IV has an NPV value of Rp77,430,028, a BCR of 1.625740809, and a PBP of 3 years, 1 month, and 2 days.
