Abstract

West Kalimantan, particularly the city of Pontianak, is known for its abundant peat soil reserves. Peat soil forms from the accumulation of organic material derived from decomposed vegetation under water-saturated conditions. In construction, the use of local materials such as peat soil can be a strategic alternative to reduce project costs and minimize environmental impact. In this study, peat soil was utilized as an additive in laterite soil mixtures intended for subgrade applications. The purpose of using peat is to reduce construction costs and minimize negative environmental impacts. This research aims to determine the effect of varying peat content—10%, 20%, 30%, 40%, and 50%—on the California Bearing Ratio (CBR) of laterite soil. The results show that the CBR value of natural laterite soil is 32.69%. When mixed with 10% peat, the CBR decreases to 12.53%; at 20%, it drops to 10.25%; at 30%, it further reduces to 6.8%; and at 40%, it falls to 4.56%. For mixtures containing 50% or more peat, no measurable CBR value was obtained. These findings indicate a significant reduction in bearing capacity as peat content increases.

Abstract

Kelurahan Sei Jawi Dalam merupakan wilayah di Kota Pontianak, Kalimantan Barat, yang rentan terhadap bencana banjir, terutama akibat kondisi geografis dan curah hujan tinggi, namun masyarakatnya belum memiliki pengetahuan dan keterampilan yang memadai dalam memetakan kawasan rawan banjir untuk mitigasi yang optimal. Oleh karena itu, tujuan utama kegiatan Pengabdian kepada Masyarakat (PKM) ini adalah memberdayakan masyarakat Kelurahan Sei Jawi Dalam melalui sosialisasi dan pelatihan pemetaan kawasan rawan banjir. Metode pelaksanaan melibatkan ceramah dan presentasi, demonstrasi langsung menggunakan teknologi GIS, diskusi kelompok, dan video edukasi untuk meningkatkan pemahaman dan keterampilan masyarakat serta aparatur sipil negara. Hasil PKM menunjukkan bahwa 100% peserta menyatakan peta mudah digunakan dan legendanya mudah dipahami, serta mereka merasa senang dan puas dengan kegiatan tersebut9. Kegiatan ini sukses mencapai tujuan utama dalam mensosialisasikan dan melatih pemetaan, yang secara nyata meningkatkan kesiapan dan respons masyarakat terhadap ancaman banjir. Manfaat signifikan yang dihasilkan adalah peta kawasan rawan banjir yang akurat sebagai acuan mitigasi dan perencanaan tata ruang, serta terjalinnya kolaborasi berkelanjutan antara akademisi dan pemerintah daerah/masyarakat.

Abstract

The Nuclear Medicine Building is a strategic healthcare facility that utilizes open radiation sources for diagnosis and treatment. Due to its high structural complexity and radiological risks, this study aims to analyze the construction management implementation of the Nuclear Medicine Building project at Dr. Soedarso Regional General Hospital, Pontianak. The research utilizes primary data from field observations and secondary data from project documents, analyzed through four critical aspects: cost, time, quality, and human resources. The study produces an Implementation Budget Plan (RAP) totaling IDR 7,904,689,106.53. Time management planning establishes a project duration of 15 weeks or 108 calendar days, utilizing Network Planning and Bar Charts to monitor the critical path. Quality management is implemented through a quality control table to ensure technical specification compliance, while human resource planning identifies a peak labor requirement of 100 workers per day during the 7th week. Analytically, the integration of cost and time in this project validates the "Iron Triangle" theory, where precision in substructure work (foundations) serves as the primary determinant of schedule success due to the specialized loading requirements of nuclear facilities. These findings suggest that for specialized medical infrastructure, radiation safety standards demand more stringent productivity coefficients compared to general building projects. The academic implication of this research indicates that the application of national AHSP regulations (PUPR No. 8 of 2023) requires adjustment for site-specific risk variables in high-hazard buildings to prevent deviations between technical planning and field reality. These results contribute to the project management literature on the necessity of integrated frameworks in enhancing the resilience of regional medical referral infrastructure.
