Abstract

Infrastructure development in Jombang Regency has increased, after the city returned to normal from the Covid outbreak over time. The natural gem subsidized housing project was built on an area of ​​7,410 m2. This landed house was built with Type 30/60 with a total of 71 housing units. This project was built by PT SAMI KARYA. In this research, data collection was obtained from developers such as weekly reports, daily reports, work schedules, RAB, and actual costs. In 2023, demand for houses in Jombang Regency will increase drastically because there are still many people who need a place to live. The methods used are Return of investment, Internal rate of return and Benefit cost ratio. The ROI calculation method is concluded to be still in profitable status as a long-term investment and can be used to invest in subsidized housing development projects with an ROI value above 16.19% as a return on investment parameter, but after carrying out a trial calculation, a profit value of 389 is obtained. % and of course achieve, even exceed the target.

Abstract

Jalan Raya Ploso, classified as a two-lane undivided road, serves as the primary route connecting Jombang Regency, Mojokerto Regency, and Lamongan Regency. This road is situated in a densely populated area that includes residential neighborhoods, commercial establishments, a terminal, and various vendors, resulting in a mix of vehicles such as large trucks, buses, motorcycles, and cars moving simultaneously. Traffic congestion frequently occurs due to several factors, including market activities, vehicle parking, and vehicles moving slowly or entering and exiting properties along the road. The aim of this research is to analyze the issues occurring on Ploso Highway and provide alternative solutions that can be implemented. The focus of the study is the unsignalized three-way intersection in front of Ploso Market. Observations indicated a road capacity of 2558 vehicles per hour (vph) with a degree of saturation (Dj) of 0.92. Since this degree of saturation does not meet the PKJI 2023 standard, which sets an ideal degree of saturation below 0.85, the researcher proposes an alternative solution involving widening the lane by 1.20 meters on the major road and 0.50 meters on the minor road.

Abstract

Profitability analysis is a key factor in evaluating the success of construction projects. This study focuses on the profitability of the Banjaragung - Pulosari road rehabilitation project in Jombang. The rehabilitation project spans 1,566 meters in length and 3 meters in width, with a project value of IDR 1,534,120,251. To determine the profit level, a profitability analysis is required. The main objective of this report is to provide an understanding of profitability analysis in the construction industry, particularly in the Banjaragung - Pulosari road rehabilitation project in Jombang, by presenting the Return on Investment (ROI), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR) methods as tools for evaluating profitability. The analysis results show a favorable outcome with an ROI of 29% and an IRR of 10.42% per year, which is higher than the East Java Regional Development Bank’s Prime Lending Rate (SBDK) of 6% per year. A BCR of 1.0669 also indicates that the benefits exceed the costs, signifying that the project has high investment return potential and is viable to undertake.

Abstract

Time Schedule is used as a guide and control tool for work execution time and productivity of workers, work tools on the project. In terms of productivity control, there are several aspects involved in the monitoring system, such as materials, tools, resources, and scheduling of project activities. Scheduling is the arrangement of resources to complete tasks in achieving targets. by involving components of activities, and time, In order to determine the optimal scheduling and budget. in accordance with time and cost limitations, this study uses the PDM (Precedence Diagram Method) method and the Crashing method through alternative scheduling with the addition of overtime of 1 hour, 2 hours, and 3 hours and knowing the acceleration cost. for each alternative. The results of the acceleration alternative with optimal costs are, alternative 1 adding 1 hour of overtime, the total cost decreased by 0.19% to Rp 3,067,337,201, -. This means that alternative 1 saves costs of Rp 5,984,598, - and is estimated to be one day faster to 119 days.

Abstract

This lesson is to construct a durable and efficient form rigid pavement by utilizing the structural analysis and material performance approach. Rigid pavement is the main choice in highway construction because of its ability to bear heavy loads and its relatively long service life. The research methodology involves structural analysis to determine the optimal thickness and type of material for rigid pavement. This structural analysis considers various factors, including the estimated traffic load, subgrade characteristics, and local environmental conditions. In addition, material performance evaluation is also carried out to select materials that are appropriate to environmental conditions and meet technical requirements. The results of this study are recommendations for rigid pavement planning that include the right thickness, optimal material type, and construction specifications that are in accordance with applicable technical standards. The results of Rigid Pavement Thickness Planning using the Bina Marga 2003 Method on the Sumbermiri - Gudo Jombang Road case study produced a concrete slab thickness of 20 cm with K-300 concrete quality. In addition, the reinforcement used has a diameter of Ø 12 mm with a distance between reinforcements of 8,5 cm.

Abstract

Proses fabrikasi baja merupakan tahapan penting dalam industri konstruksi sehingga memerlukan pengawasan dalam proses produksi untuk menghasilkan kualitas produk yang baik. Setiap tahap, mulai dari penerimaan material hingga pengiriman produk akhir, harus melalui serangkaian inspeksi untuk memastikan kesesuaian terhadap standar teknis dan spesifikasi proyek. Tujuan penelitian ini adalah memahami dan menerapkan proses inspeksi dalam proyek konstruksi, serta mengidentifikasi langkah-langkah penting dalam diagram alir inspeksi yang digunakan untuk memastikan kualitas produk dan kepatuhan terhadap standar yang ditetapkan. Metode yang digunakan dalam penelitian ini adalah metode pengamatan dan observasi yang dilakukan di PT. Pamitra Jaya Konstruksi selama tiga bulan, dari 2 September hingga 25 November 2024. Prosedur inspeksi mencakup pemeriksaan material awal, pemotongan (pre-cut), perakitan, pengelasan, pengujian non-destruktif (NDT), penyelesaian akhir, hingga perlakuan permukaan seperti pengecatan atau galvanisasi. Laporan inspeksi disusun di setiap tahapan untuk mendokumentasikan hasil pemeriksaan dan menjamin proses pelaksanaan dan kualitas material. Hasil inspeksi menunjukkan bahwa penerapan diagram alir inspeksi efektif dalam meningkatkan akuntabilitas dan efisiensi operasional.
