Abstract

In transportation engineering, road pavement is commonly categorized as either flexible pavement or rigid pavement. The pavement demonstrates a distinct capacity to endure a variety of loads, including compressive and tensile loads. The capacity to endure compressive and tensile forces is extremely important, especially in the field of pavement construction, as it ensures both the longevity and the safety of the pavement. The objective of this study was to evaluate the capacity of hot mix asphalt to endure compressive and tensile pressures. The experimental methodology employed four different wire mesh deployment configurations on hot asphalt mixtures, utilizing three-point flexural test equipment. The data indicates the most effective method for mimicking hot mix asphalt involves adding a wire mesh layer at a depth of 30 mm below the surface of the experimental specimen. The particular modeling method showed a measurement of flexural resistance up to 291.85 kN. The study's findings indicate that the hot asphalt mixture exhibits a state of balance in its capacity to endure both compressive and tensile pressures. Incorporating a wire mesh layer within the middle section of the hot asphalt mixture has been perceived to enhance its ability to withstand tensile loads, hence improving its overall performance.

Abstract

The Occupational Safety and Health Management System (SMK3) is an integral part of the labor protection system. In construction services, it serves to minimize and prevent moral and material losses, loss of working hours, as well as risks to human safety and the surrounding environment, thereby supporting effective and efficient performance during the construction process. This study evaluates the implementation of SMK3 in the Krueng Keureuto Dam Construction Project in North Aceh Regency. A quantitative research approach was applied, with data collected from 30 respondents comprising the project manager, construction manager, safety officers, technical administration staff, document controllers, public relations officers, quality control staff, site engineers, field supervisors, logistics staff, warehouse staff, and project controllers. The research variables include the implementation of occupational safety and health, occupational safety and health regulations and procedures, management commitment to safety, work environment, and evaluation of occupational safety and health practices. The results show that the implementation of SMK3 in the Krueng Keureuto Dam Construction Project achieved a score of 94.22%, which falls into category 3, indicating a satisfactory level of performance

Abstract

Perencanaan dan pengendalian biaya merupakan aspek penting pada proyek konstruksi jalan karena menentukan kemampuan kontraktor menyelesaikan pekerjaan secara efisien tanpa mengurangi mutu dan spesifikasi teknis. Penelitian ini mengevaluasi efisiensi biaya pelaksanaan melalui perbandingan Rencana Anggaran Biaya (RAB) dan Rencana Anggaran Pelaksanaan (RAP) pada Proyek Pengaspalan Jalan Pelita Sagop Jaya - Indra Makmur Kabupaten Aceh Timur. Penelitian menggunakan pendekatan studi kasus kuantitatif dengan sumber data berupa dokumen kontrak, RAB, gambar rencana, spesifikasi teknis, observasi lapangan, dan data biaya pelaksanaan. Analisis dilakukan melalui identifikasi item dan volume pekerjaan, rekalkulasi RAP berdasarkan kebutuhan sumber daya aktual dan harga satuan lokal, serta perbandingan nilai agregat RAB dan RAP. Hasil penelitian menunjukkan nilai RAB/nilai kontrak sebesar Rp1.374.308.273,92, sedangkan nilai RAP hasil rekalkulasi sebesar Rp1.264.363.612,01. Selisih keduanya sebesar Rp109.944.661,91 atau 8,0% dari nilai kontrak. Setelah dialokasikan 10% dari selisih untuk overhead dan risiko, potensi margin pelaksanaan diperoleh sebesar Rp98.950.195,72 atau 7,20%. Hasil ini menunjukkan bahwa perbandingan RAB-RAP dapat digunakan sebagai indikator efektivitas pengendalian biaya pada proyek jalan skala kecil hingga menengah.
