Abstract

The calculation of construction cost estimates by planning consultants generally still relies on Microsoft Excel. This conventional method is prone to errors due to inaccuracies in data interpretation and the complexity of building design calculations. Such conditions may result in significant discrepancies, potentially leading to cost overruns. Therefore, a more efficient and accurate approach to cost estimation is required, one that can also present project information comprehensively. This study aims to compare the calculation results of volume and Cost Budget Plan (RAB) for reinforced concrete works between the conventional method used by planning consultants and the Building Information Modeling (BIM) 5D method. The research was conducted as a case study on the SSC Tower Building Project in Balikpapan using Autodesk Revit software to generate BIM-based cost estimates. The results indicate that the difference in volume calculation for reinforcement and concrete works is 0%, and the difference in cost estimation for reinforced concrete works is also 0%. This finding suggests that the BIM 5D method produces results consistent with those of the conventional consultant method. In conclusion, BIM 5D application in cost estimation provides results as accurate as the conventional method, with added advantages in visualization, interactive project information, and efficiency in the decision-making process.

Abstract

Construction project delays are a common issue that significantly affect cost, quality, and completion time. This condition occurred in the construction of the PT Telkom Closed Warehouse in Balikpapan, which was originally planned to be completed within 90 calendar days but experienced a 28-day delay, resulting in a total completion time of 118 days. The delay was mainly caused by weak supervision and the absence of a structured planning method from the beginning. This study aims to analyze critical activities using the Precedence Diagram Method (PDM) and to calculate the probability of project completion using the Program Evaluation and Review Technique (PERT). The analysis results indicate that concrete structure work, wall installation, flooring, roofing, and mechanical-electrical work were identified as critical path activities. In addition, the PERT method provided an overview of the probability of achieving the actual project schedule. The conclusion of this research emphasizes that the application of PDM and PERT can help contractors plan schedules more accurately, reduce the risk of delays, and optimize the use of project resources.

Abstract

This Community Service (PkM) activity aims to enhance the digital marketing capacity of Micro, Small, and Medium Enterprises (MSMEs) in Munjul Village, Ciambar District, Sukabumi Regency through strengthening the role of the Koperasi Merah Putih. Munjul Village has local economic potential based on cassava-based products; however, the utilization of digital technology for marketing remains limited. The implementation methods included field surveys, digital literacy training, assistance in creating social media and marketplace accounts, and institutional strengthening of the cooperative as an integrated digital marketing center. The results indicate an improvement in participants’ knowledge and skills in digital marketing, the establishment of business social media accounts, and the ability to create simple promotional content. Approximately 80% of participants understood the benefits of social media in increasing sales and the cooperative’s role in collective promotion, while 90% stated that the program was beneficial for strengthening sustainable local economic development. Overall, the evaluation shows increased knowledge, understanding, and skills in cooperative-based digital marketing toward a sustainable village economy.
