Abstract

The calculation of indirect costs carried out by contractors so far has no reference or there is no standardized design to be a benchmark. For this reason, researchers will analyze the primary and secondary data of this study to determine the indirect costs of direct costs or against the contractors' contracts. This study analyzes the amount of indirect costs in the Kanor District Sports Facilities Development project of Bojonegoro Regency and looks for a relationship between indirect costs and bid prices with time performance on the Kanor District Sports Facilities Development project of Bojonegoro Regency. This research method uses data processing and indirect cost RAB making. and using analysis methods with linear regression statistical analysis. Indirect costs in the Kanor District Sports Facilities Development project are allocated to 4 (four) main things, namely tax and insurance costs (61.49%), risk costs (7.21%), and overhead costs (8.62%), general costs (8.325) quality costs 4.36%) where the percentage is calculated from the total amount of indirect costs. From the linear regression analysis it can be concluded that indirect costs affect the project work time. Bid price has no effect on project work time. Indirect costs and bid prices affect the time of work.

Abstract

The construction project management for Wadungasri Sidoarjo Market Drainage Normalization aims to achieve cost, quality, and time objectives within a 100-day timeframe. This study addresses a 7.44% delay experienced by contractors, seeking to establish early warning mechanisms for poor project performance. The Earned Value Method is employed, integrating time and cost value concepts. Key indicators such as Cost Variance (CV), Schedule Variance (SV), work productivity index (CPI), time productivity index (SPI), project completion cost forecast (EAC), and project completion schedule forecast (ECD) are utilized. The results reveal a required cost of Rp 563,044,547.85 (ETC) and a 65-day timeframe (ETS) at the end of the 7th week, with a 0.64% increase in project completion cost (EAC) over the contract cost. The project completion time (EAS) is estimated at 114 days, reflecting a 0.14% extension. The analysis emphasizes the importance for construction service providers to implement efficient methods and consistent supervision to avoid delays in the Wadungasri Sidoarjo Market Drainage Normalization project.

Abstract

Since customer support is time-limited, chatbot programs can assist potential online store visitors before they make a purchase. The general public cannot always answer inquiries or respond to customer requests. Virtual customer support allows potential customers to contact vendors regarding products they wish to purchase. This technology is very helpful in providing quick and accurate answers to various customer concerns and issues. The study focuses on the online retail environment where customer support is crucial for potential buyers before making a purchase. The Artificial Intelligence Markup Language (AIML) and Semantic Ontology were used by A.L.I.C.E. (Artificial Internet Linguistic Computer Agency) to develop an AI chatbot application. There are no online stores that use virtual customer service (chatbots) for customer support, so Batik Cloth, an application that offers batik textiles for sale in Malang, was chosen as the online store chatbot application for this study. Creating a chatbot with semantic capabilities involves using ontologies to process queries with more precise meaning. It achieves 92% accuracy for 15 types of relevant queries and responses, followed by 10 frequently asked questions as answers. Created by a potential buyer. Virtual customer support systems (chatbots) can respond to queries with similar terms or meanings by employing ontologies and semantics to deliver answers that fit the queries.

Abstract

The implementation of construction work has the main targets in construction management, such as construction costs, quality of construction work and construction implementation time. Construction activities can be declared successful in their management if they produce work products with the quality criteria that have been determined, on time, and according to the agreed costs. Using EVM (Earned Value Method) in project management can be used to determine cost performance and implementation time during the project and the indicators used for analysis include: BCWP (Budget Cost of Work Performance), BCWS (Budget Cost of Work Schedule), ACWP (Actual Cost of Work Performance), SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), EAS (Estimated At Schedule) and ETS (Estimated Temporary Schedule). By using this method in the Sports Facilities Construction Project, Kecamatan Kedewan, Kabupaten Bojonegoro, the ACWP (Actual Cost of Work Performed), BCWP (Budgeted Cost of Work Performed), and BCWS (Budgeted Cost of Scheduled) values were obtained. The CV value obtained <0 in weeks 1 to 7 indicates that the costs incurred were greater than the plan, but in weeks 8 to 15 the CV value >0 means that in that week the costs incurred were less than the plan. Meanwhile, meaning the project is experiencing a delay from plan. The estimated of the completion budget requirement obtained from the ETC (Estimate to Compile) value is Rp. 3,345,105,521.28, while the estimated final total project cost obtained from the EAC (Estimate at Complete) value is Rp. 5,680,868,593.22.

Abstract

Kediri is the third largest city in East Java after Surabaya and Malang with a population growth of 289,418 people in 2023. The International Airport will open at the end of 2023 in Kediri. However, rapid population growth has also led to an increase in mobility and the number of motorized vehicles on the streets of Kediri City, including at the research site in Dhoho Plaza. The analysis of the signaled intersection was carried out using the MKJI 1997 method, and Visual PTV Vissim for three days on Monday, Friday, and Sunday. Based on the results of the analysis, a cycle time of 90.7 was obtained which affected saturation in each arm of the intersection. There is a potential reduction in signal light waiting time from 135 seconds to 118 seconds by repairing side obstacles. The solution to overcome side obstacles is to improve facilities such as traffic lights and adjust the timing of signal lights. The change in the value of side barriers also has a significant impact on waiting times, queues, and fuel costs at the intersection of Pasar Pahing, with congestion cost efficiency reaching Rp. 22,679,183 in the next 5 years.

Abstract

In project implementation, change orders frequently arise post-contract signing between the owner and contractor. These changes often stem from design modifications or budget adjustments by the owner. Contractor-initiated change orders result from disparities between design plans and bill of quantities, insufficient design details, impractical field conditions, complex design execution, and challenges in material mobilization. Poorly managed change orders can lead to increased costs, delays, and diminished contractor performance. To mitigate change orders, this study employs change order correlation analysis using original data, evaluating change order ratio (COR), change order ratio in addition (CORA), and change order ratio in subtraction (CORS). Analyzing six construction projects, the study concludes that the average Change Order Ratio Index (COR) is 26%, indicating a 26% change from the original contract value. The average Change Order Ratio in Addition (CORA) is 16%, signifying 16% of changes result from additional work. The average Change Order Ratio in Subtraction (CORS) is 10%, indicating 10% of changes stem from work being less than the original contract value.

Abstract

Indonesia as an archipelago state is still need an equality development with the intention in achieving the goals to fulfill the requirement of structure and infrastructure. The economy that has experiencing growth, it can be seen with the rising of the demand for supply of electricity power whether it is coming from domestic moreover from industrial usages. Lampung Province, as one of the regions which is in a continuation to develop, requires the support of electric power, which at its peak load reaches 1200 MW, while the capacity of the existing power plant can only produce 700 MW, therefore the construction of a 275 kV Gumawang-Lampung 1 SUTET interconnection network with a capacity of up to 2000 MW was established to meet these requirements. Based on the time schedule which noted that the duration of foundation work started with the excavation, concreting until the reaches of it's curing time in 28 days is 42 days in 2023 December 13th is on try to speed up can be curing in 2023 December 8th, so the schedule tower installation in 2023 December 9th will be on time. Due to this delay, the researcher intends to carry out an acceleration analysis starting with preparing a network diagram using the Microsoft Project software, followed by the crashing process by adding groups of workers and tools of any activities on the critical path. The next step is to calculate the crash cost and cost slope values using the time cost trade off (TCTO) method.
