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

The significant growth in the number of vehicles in Mamuju Regency, West Sulawesi, along with the development of infrastructure such as Tampa Padang Airport and Belang-Belang Port, creates the potential for traffic congestion, especially at the intersection of Jl. Poros Mamuju-Kalukku-Jl. Tampa Padang Airport Access. This study aims to analyze the existing conditions and performance of traffic movements at the unsignalized intersection based on the Indonesian Road Capacity Guidelines (PKJI) 2023. The method used is a quantitative approach through a seven-day traffic survey during peak hours. Data collected included traffic volume, intersection geometry, and environmental conditions around the intersection. Analysis using the Indonesian Road Capacity Guidelines (PKJI) 2023 was conducted on the intersection capacity, and intersection performance. The results showed that the peak hour of vehicles occurred on Monday, May 19, 2025 at 07.00-08.00 a.m. The volume of vehicles was 1111 vehicles / hour or 612.6 smp / hour with a degree of saturation (Dj) 0.20, delay (T) 6.8, queue opportunities (Pa) 2-9%. And on Sunday May 25, 2025 at 10:00-11:00 am, the volume of vehicles was 638 vehicles / hour or 412 smp / hour with a degree of saturation (Dj) 0.14, delay (T) 5.9, queue opportunities (Pa) 1-6%. Performance assessment based on PKJI 2023 parameters provides an overview of the traffic service of the intersection in the level of service (LOS) B category, which means that the traffic flow conditions are good.

Persimpangan merupakan bagian penting dari sistem jaringan jalan yang memerlukan pengaturan khusus untuk mengoptimalkan pergerakan dan meminimalkan konflik lalu lintas. Tujuan dari penelitian ini untuk mengetahui kinerja arus lalu lintas pada jalan mayor (Jalan Jend Ahmad Yani) dan jalan minor (Jalan Abu bakar lambogo dan Jalan Bukit Madani) dan mengetahui dampak arus lalu lintas terhadap tingkat pelayanan simpang jalan mayor dan jalan minor kota Parepare. Jenis penelitian yang digunakan adalah penelitian deskriptif kuantitatif. Dari hasil penelitian menunjukkan bahwa kinerja arus lalu lintas di hari kerja (Selasa) pada jalan mayor dan jalan minor memiliki volume kendaraan jam puncak sebesar 4.691 kend/jam pada pukul 08.00-09.00 WITA. Adapun nilai kapasitas (C) yang dihasilkan yaitu 3180,435 smp/jam dengan nilai derajat kejenuhan (DJ) sebesar 0,61, Sedangkan tundaan (T) yang dihasilkan selama 10,75 det/smp dengan peluang antrian (Pa) sebesar 0,19 sampai 33%.

Latar belakang penelitian ini didasari oleh kebutuhan untuk mengurangi dampak lingkungan akibat produksi semen, yang menghasilkan emisi karbon dioksida (CO₂) tinggi, dengan memanfaatkan fly ash untuk menggantikan sebagian penggunaan semen. Tujuan dari penelitian ini untuk menganalisis durabilitas bata ringan berbasis fly ash sebagai material konstruksi ramah lingkungan. Jernis pernerlitian yang digurnakan pada pernerlitian ini adalah erksperrimern kurantitatif dengan menentukan komposisi terbaik dari campuran bata ringan dengan tambahan fly ash yang di lakukan penelitian di labolatorium program studi teknik sipil dengan menggunakan variasi campuran fly ash pada bata ringan (CLC). Pengujian meliputi daya serap air, kuat tekan, dan keausan setelah masa umur 28 hari. Temuan penelitian ini menunjukkan bahwa penambahan fly ash 0%, 5%, 10%, 15% menghasilkan persentase optimal yang mampu menurunkan daya serap air sebesar 8,60% sehingga lebih tahan terhadap kelembapan air dan meningkatkan kuat tekan sebesar 5,33 MPa. Selain itu, keausan bata ringan cenderung menurun seiring bertambahnya kadar fly ash, hal ini ditunjukkan pada peningkatan ketahanan aus sebesar 7,60%. Variasi campuran dengan persentase fly ash tertentu terbukti memberikan performa terbaik, sehingga limbah industri ini berpotensi dimanfaatkan sebagai material konstruksi yang lebih ramah lingkungan dan mendorong pertumbuhan pembangunan yang berkelanjutan.

This study investigates the impact of road gradient on fuel consumption, fuel rate (FR), and CO₂ emissions in freight transport vehicles with two-axle and three-axle configurations. The research was conducted on a 250-meter road segment with a 0.067 rad (~7%) gradient in front of Taman Rekreasi Datae, Sidenreng Rappang Regency, South Sulawesi, Indonesia. A quantitative mathematical model, based on vehicle technical parameters and empirical formulations from previous studies, was applied. Results show that increasing the gradient from 0 to 0.067 rad raised fuel consumption in two-axle trucks from 0.0356 L to 0.0857 L and in three-axle trucks from 0.1463 L to 0.3269 L. The FR for two-axle trucks increased from 0.0014 L/s to 0.0056 L/s, while for three-axle trucks it rose from 0.0033 L/s to 0.0124 L/s. CO₂ emissions from two-axle trucks increased from 0.0958 kg to 0.3941 kg, and from 0.2310 kg to 0.8807 kg for three-axle trucks. The relative increase was higher for two-axle trucks (311%) than for three-axle trucks (281%), due to axle load distribution, engine capacity, and transmission ratio. These findings highlight the need to consider vehicle configuration and topography in route planning to minimize fuel consumption and emissions in hilly regions.
