Abstract

Pasar Pagi Samarinda, located in Gajah Mada, Samarinda, East Kalimantan, is a staple food market that is planned to be upgraded to a Type A market through a development project outlined in the Detail Engineering Design (DED). According to the DED document prepared by the consultant, the total project value is estimated to be IDR 364,459,686,000. To improve financing efficiency while maintaining construction quality, a Value Engineering (VE) analysis is required. The goal of Value Engineering is to analyze the construction design to achieve the desired function at a lower cost without compromising quality. This study aims to identify design components that can be replaced with more cost-effective alternatives while still being effective. The research method used is descriptive, both qualitative and quantitative, with analysis stages according to Value Engineering standards. The first stage involves gathering information about the initial project design. Next, a functional analysis is carried out to determine the needs of each component. During the creativity stage, alternative, more cost-efficient designs are proposed. The evaluation phase compares the alternatives based on cost and benefits, and finally, the recommendation phase provides the most cost-efficient design solution. The results show that replacing the bored pile foundation design with a pile foundation can significantly reduce construction costs. Using the pile foundation reduces the total project cost to IDR 379,536,168,000, lower than the initial design with a bored pile foundation valued at IDR 371,486,210,000. The cost savings of IDR 8,049,958,000, or about 2.12% of the total project value, indicate that the pile foundation alternative is an effective solution for reducing costs without compromising the construction quality of Pasar Pagi Samarinda

Abstract

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.

Abstract

Roofing work plays an important role in hospital building construction because it affects costs, time, comfort, and structural performance. In the Muhammadiyah Rodliyah Achid Moga Pemalang Hospital Building Construction Project, the existing Kliplok zincalume roofing system was costly and had low productivity. This study aims to obtain more efficient roof design alternatives through Value Engineering (VE) based on SAVE International standards, including information gathering, FAST function analysis, creative stage, evaluation, and development. Two alternatives were developed: Alternative 1 uses SDS tapping screws with 3.0 mm CNP purlins, and Alternative 2 uses 2.3 mm CNP purlins. Both alternatives fulfill the main function with a value index >1.0. Alternative 1 provides the highest cost savings of 27.96%, increases productivity from 25 to 35 m²/person-day, and reduces the implementation duration by four days. A 10-year Life Cycle Cost analysis shows the lowest cost in Alternative 1. Value Engineering has proven to be effective in improving the cost efficiency and performance of hospital roof work.

Abstract

Pengendalian proyek memiliki tiga factor penting yaotu, biaya, waktu dan mutu. Salah satu dari factor yang harus diperhatikan dalam memperhitungkan yaitu waktu dan biaya untuk dapat menjadikan proyek menjadi efektif dan efisien. Peneliti ini memiliki tujuan untuk mengukur kinerja proyek, membuat reschedule yang optimal, efektifitas waktu dan efisiensi biaya pada proyek Pembangunan Gedung Kantor Pengadilan Tinggi Agama Bali. Pada penelitian ini menggunakan Metode Earned Value Management (EVM) dan Crash Program dengan data yang dibutuhkan untuk Analisa yaitu data primer dan data sekunder. Data yang sudah terkumpul selanjutnya analisis kinerja waktu dan biaya proyek serta Analisa efisiensi biaya terhadap alternatif jam kerja lembur dan penambahan tenaga kerja. Hasil kinerja proyek pada Metode Earned Value Management (EVM) secara biaya surplus mulai pada Minggu ke 3 hingga minggu ke 37 dan minggu ke 42 hingga Minggu ke 47. Namun mengalami minus biaya pada minggu ke 38 hingg minggu ke 41, serta secara kinerja waktu penyelesaian sesuai dengan rencana time schedule. Sedangkan untuk reschedule dan Crash Program yang bisa dikatakan optimal, dengan memperhitungkan nilai penambahan tenaga kerja dengan efisiensi biaya sebesar 2,73% terhadap total cost dengan durasi normal dan efektifitas waktu selama 21 hari kalender lebih cepat dari rencana.
