This research is caused by the need to improve time and cost efficiency in the implementation of construction projects, particularly in the construction of multi-story buildings such as the SDN 16 Pinrang project. Until now, project scheduling has relied on the Bar Chart method, which is not capable of optimally identifying dependencies between activities. The purpose of this study is to analyze the application of the Critical Path Method (CPM) in scheduling multi-story building construction projects to enhance project execution effectiveness. The research method used is a descriptive quantitative approach, with data collected through document studies, field observations, and secondary data analysis of the Bill of Quantities (RAB). The results show that the CPM method is effective in identifying critical activities that determine the total project duration. Out of 10 project activities, Five are non-critical and have slack time that can be utilized for acceleration without affecting the main critical path. Through the optimization of parallel work and the use of slack time, the project duration can be reduced from 26 weeks to 18 weeks, resulting in a cost saving of IDR 431,525,263.65 or approximately 23.55% of the initial total budget

Muh. Wahyu Yusuf, Jasman Jasman, Imam Fadly — Mon, 27 Oct 2025 08:18:36 +0000

Jenderal Sudirman Road, located in Pinrang Regency, is one of the main roads with high traffic intensity. The large traffic volume is influenced not only by daily community activities but also by the rapid development of shopping areas and its role as a primary access to several government offices. The growth of commercial and service centers has drawn significant vehicle movements, both private and public, leading to higher congestion. This condition requires a performance study to evaluate the road’s Level of Service (LOS), degree of saturation (DS), and capacity in accommodating increasing traffic flow. The objective of this study is to provide a clear picture of the existing condition of Jalan Jenderal Sudirman and serve as a foundation for effective urban traffic management and planning, with reference to the 2023 Indonesian Road Capacity Guidelines (PKJI). Data collection was conducted on Thursday, August 14, 2025 to represent a weekday and on Saturday, August 16, 2025 to represent weekend traffic conditions. The results indicate that congestion occurs mainly during peak hours, especially between 16:00 and 18:00 WITA. Analysis using PKJI 2023 recorded the road’s capacity at 2,632 PCU/hour under low side-barrier conditions. Peak traffic volume reached 2,426.07 PCU/hour, producing a degree of saturation of 0.92. This corresponds to LOS E, which reflects unstable flow, near-capacity conditions, and frequent reductions or halts in vehicle speed. Thus, Jalan Jenderal Sudirman can still accommodate current traffic demand but is operating under critical conditions, requiring immediate traffic management measures to handle congestion and anticipate future growth.

Based on several previous studies, it was found that there were differences in justifications regarding the influence of volume, speed, and traffic density on the level of noise on the highway. The aim of this research was to analyze the influence of volume, speed, and density on the noise level. The research method used a descriptive and parametric statistical approach. The results of the study indicated that the influence of vehicle volume on noise was 46.6% with a direct relationship. The influence of speed on noise was 5.6% with an inverse relationship. The influence of traffic density on noise was 64.8% with a direct relationship. The traffic density variable had the greatest impact on the noise level on the highway. The relationship between vehicle speed and noise was inverse only up to a speed of 70 km/h. If the average vehicle speed exceeded 70 km/h, it was possible for there to be a direct relationship, meaning that as the vehicle speed increased, the noise level also increased.

Anrias Anrias, Minson Simatupang, Hasmina Tari Mokui — Mon, 27 Oct 2025 08:27:35 +0000

Penelitian ini menyoroti pengelolaan risiko Keselamatan dan Kesehatan Kerja (K3) pada proyek pembangunan Gedung DPRD Kabupaten Bombana, yang bertujuan meminimalkan potensi kecelakaan serta mendukung peningkatan produktivitas konstruksi. Metode yang digunakan berupa pendekatan kuantitatif deskriptif melalui penyebaran kuesioner, observasi di lapangan, dan telaah dokumen Rencana Anggaran Biaya (RAB). Sebanyak 30 responden, meliputi manajer proyek, pengawas, petugas K3, serta pekerja, dilibatkan untuk mengidentifikasi risiko dan mengevaluasi implementasi K3. Temuan penelitian memperlihatkan bahwa faktor utama dalam penerapan K3 ialah ketersediaan serta pemakaian Alat Pelindung Diri (APD), konsistensi pengawasan, intensitas pelatihan, dan pemasangan rambu keselamatan. Walaupun K3 sudah diterapkan, pelaksanaannya masih kurang optimal karena disiplin pekerja dalam penggunaan APD rendah dan pengawasan belum maksimal. Analisis anggaran menunjukkan alokasi biaya K3 masih di bawah standar yang dipersyaratkan SE Kementerian PUPR No. 11/SE/M/2019. Oleh karena itu, peningkatan anggaran K3, pengawasan ketat, pelatihan berkesinambungan, dan pembentukan budaya keselamatan menjadi langkah penting untuk mewujudkan zero accident. Hasil riset ini diharapkan dapat menjadi rujukan praktisi maupun akademisi dalam memperkuat manajemen risiko K3 pada sektor konstruksi.

Pengaruh Substitusi Abu Sekam Padi terhadap Kuat Tekan dan Workability Beton Self-Compacting Concrete (SCC) sebagai Upaya Pemanfaatan Limbah Ramah Lingkungan

Mon, 27 Oct 2025 08:34:24 +0000

The increasing concern for environmental sustainability has prompted innovations in the construction industry, particularly through the utilization of agricultural waste as supplementary cementitious materials. This research examines how replacing cement with rice husk ash (RHA) influences the compressive strength and workability of Self-Compacting Concrete (SCC). A comparative experimental approach was used, with Portland Composite Cement (PCC) serving as the primary binder and RHA added as a partial cement substitute at proportions of 2.5%, 5%, and 10% by weight. Prior to developing the mix design, the physical and mechanical characteristics of the aggregates were assessed following Indonesian National Standards (SNI). The compressive strength of cylindrical specimens (15 cm × 30 cm) was measured at 14 and 28 days of curing. The findings show that replacing 5% of the cement with RHA yielded the greatest compressive strength, reaching 35.7 MPa at 28 days, exceeding the strength of the control mix and other replacement levels. This enhancement is attributed to the pozzolanic activity of the amorphous silica in RHA, which improves the concrete’s microstructure and decreases its porosity. However, exceeding 5% replacement leads to reduced performance due to excessive dilution of cementitious content. Therefore, rice husk ash can be effectively utilized as an eco-friendly cement replacement up to an optimal proportion of 5%, supporting the development of sustainable construction materials in Indonesia

Pengembangan Model Prediksi Kinerja Proyek Menggunakan Earned Value Management Berbasis Data Progres Mingguan

Annisa Azhar Firdausi, Iwan Ristanto, Faisal Burhanudin — Mon, 27 Oct 2025 15:55:26 +0000

Construction projects are inherently complex due to the involvement of human resources, materials, equipment, costs, and schedules. In Indonesia, project delays and cost overruns remain common issues, often caused by weak monitoring and control mechanisms. Conventional reporting methods, which rely mainly on progress percentages or S-curves, are limited because they do not provide integrated information on cost, time, and performance. This study develops a project performance prediction model using Earned Value Management (EVM) based on weekly progress data, with a case study on the construction of the LPPM & BPMI Building at Veteran Bangun Nusantara University. The research applies an applied case study approach, utilizing project documents and weekly progress reports as the primary data. Indicators such as Planned Value (PV), Earned Value (EV), Schedule Variance (SV), and Schedule Performance Index (SPI) were calculated for weeks 1–13. The analysis shows that while the project was initially ahead of schedule (positive SV and SPI > 1 in weeks 1–5), performance declined significantly after week 6. At week 13, the SV turned negative with an increasing gap between planned and actual progress, while the SPI dropped to 0.44, indicating serious schedule inefficiency. Forecasting results using EVM predict that the project, initially planned for completion in 25 weeks, will require 41 weeks, resulting in a delay of approximately 16 weeks.
