Abstract

Kuat dan aman merupakan syarat mutlak berdirinya suatu konstruksi, semua kontruksi yang direncanakan akan ditopang oleh tanah. Tujuan penelitian ini untuk Mengetahui sebrapa besar daya dukung tiang pancang tunggal dan kelompok yang bekerja pada fondasi Tangki Panel 16 m3. Perhitungan untuk daya dukung fondasi tiang pancang kayu galam menggunakan data Sondir dengan 2 metode yaitu metode deRuiter & Beringen dan Metode Schmertmann dan Nottingham (1975) dan untuk menghitung beban yang bekerja pada bangunan menggunakan perhitungan manual. Berdasarkan hasil perhitungan bebean struktur atas yang bekerja sebesar 21,0325 ton, dapat disimpulkan menggunakan metode Schmertmann-Nottingham fondasi aman terhadap beban yang bekerja dikarenakan Qgroup lebih besar dari beban yang bekerja, sedangkan dari hasil perhitungan menggunakan metode deRuiter & Beringen fondasi tidak aman terhadap beban yang bekerja dikarenakan Qgrup lebih kecil dari beban yang bekerja

Abstract

In 2022, the most extensive plantation in Balangan Regency was a rubber plantation, covering an area of 37,901 hectares and producing 24,375 tons. To enhance the role and competitiveness of rubber commodities, one of the necessary efforts is to improve the quality of processed rubber materials. This requires a facility for processing, storing, and marketing rubber raw materials, whether in the form of latex, lump, slab, smoked sheet, or crepe. PT. Asabaru Dayacipta Lestari (PERSERODA), a regional company in Balangan Regency with a rubber plantation of 31,383 square meters in Batumandi District, plans to construct a warehouse for processing, storing, and marketing Processed Rubber Materials, along with office and employee accommodations. To support this, a technical study is required for the planning and construction of a PRM warehouse and its supporting facilities, including an office and employee accommodations in Kasai Village, Batumandi District, Balangan Regency. Cost analysis based on the National Building Unit Price (HSBGN) issued by the Regent includes several classifications to determine the estimated cost of physical construction, planning, supervision, and activity management. The cost estimate in this technical study is a rough estimate to be used for budgeting and as a basis for evaluating project performance. The calculation is based on the 2021 South Kalimantan Province National Building Unit Price (HSBGN), which is converted to 2024 using inflation data from the Central Statistics Agency (BPS) of South Kalimantan Province. Based on the 2021 South Kalimantan Province HSBGN for Balangan Regency, the estimated cost (budget) for the construction of a Processed Rubber Materials warehouse, office, and employee accommodations is Rp. 18,778,365,000. This cost includes estimates for planning, supervision, activity management, and construction. This estimated cost (budget) is still at an early stage and can be continued to the next stage, which is detailed planning (DED), technical specifications, and a detailed budget plan (RAB). For data accuracy, a field survey or soil testing (sounding, etc.) should be conducted. Keywords : warehouse, processed rubber materials, cost estimation

Abstract

This research investigates an alternative structural design for the approach bridge of a pedestrian suspension bridge by replacing reinforced concrete with structural steel to address construction challenges in remote areas. The study focuses on the Lobang Baru Pedestrian Suspension Bridge in Banjar Regency, South Kalimantan, where the Kulur Tengah side faces significant logistical constraints including limited accessibility, frequent river flooding, and inadequate transportation infrastructure for concrete materials. Using finite element modeling analysis, two structural systems were comprehensively evaluated: the existing reinforced concrete design and a proposed steel-based alternative. The steel alternative design employs H-shaped steel sections for main girders (H350x350-12/19), diaphragms (H200x200-8/12), and cross girders (H300x300-10/15), with hollow structural sections (HSS 508x9.5) for columns and 8mm steel deck plates. Results demonstrate substantial improvements: total structural weight decreased by 72.2% from 55.92 tons to 15.55 tons, with the weight per unit length reduced from 3.43 ton/m to 0.65 ton/m. The steel design eliminated 23.79 m³ of concrete from the superstructure while requiring only a single support at the pillar block instead of dual supports at both pillar and anchor blocks, thereby reducing structural complexity and foundation loads. Although substructure concrete volume increased by 27.12 m³ due to the separate abutment construction, the overall design significantly improves constructability through prefabrication, modular assembly, and reduced vulnerability to environmental conditions. These findings validate the technical and practical feasibility of steel-based approach structures for pedestrian suspension bridges in challenging rural environments, offering a replicable solution for similar infrastructure projects across Indonesia and other developing regions facing comparable geographic and climatic constraints.
