Abstract

Good project planning can minimize delays, high costs, and technical adjustments. However, the Nusa Guest House project in Banjarbaru by CV Senusa Group was carried out without comprehensive planning and without involving a formal planning consultant, relying only on floor plans and workers' experience. This study aims to evaluate the effectiveness of projects with and without planning by analyzing the Budget Plan and schedule using the Precedence Diagramming Method (PDM). The compiled budget shows a cost of Rp 2,918,133,500, while the owner allocated Rp 4,406,000,000, resulting in a difference of Rp 1,487,866,500 (excluding VAT). After adding 12% VAT, the difference becomes Rp 1,666,410,480. The project runs for 564 days, from January 2, 2023 to September 12, 2024, with 85% progress achieved. The study concludes that lack of comprehensive planning increases the risk of inefficiency in cost and time. Keywords: Project Planning, Budget Plan, Time Schedule, PDM

Abstract

The population and motor vehicle growth in Marabahan City, South Kalimantan, as a result of the designation of East Kalimantan as the new capital of Indonesia, has led to a significant increase in traffic volume, particularly at the Marabahan four-leg intersection—a non-signalized intersection that serves as a key route for community activities during peak hours. This study aims to evaluate the current performance of the intersection, determine when its performance begins to decline, and propose appropriate mitigation measures, using methods based on the 2023 Indonesian Highway Capacity Guidelines (PKJI 2023) and analysis conducted with Excel. Traffic volume data collected over 12 hours on November 24 and 25, 2024, along with population data from Barito Kuala Regency, were analyzed, revealing peak hours on Sunday at 17:00–18:00 and Monday at 07:15–08:15, with an existing performance showing a level of service C. Forecasting indicates a decline in performance to the level of service D by the 14th year,  necessitating intervention. Two alternative solutions are proposed: converting the intersection into a signalized (APILL) intersection with an average delay of 25 seconds/pcu (LOS B) and widening the geometric layout, resulting in a degree of saturation (DS) of 0.873, delay of 16.674 seconds/pcu, queue probability of 45.506%, and maintaining a level of service C.Keywords: Intersection Performance, Indonesian Highway Capacity Guidelines 2023 (PKJI 2023), Signalized Intersection (APILL), Level of Service Index, Capacity, Degree of Saturation.
