Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ Consultation: https://wa.me/6281338718071/ English Version Abstract Precise financial estimation, or Rencana Anggaran Biaya (RAB), is the bedrock of project management in the construction industry. For river stone foundation ( pondasi batu kali ) projects, inaccuracies in volume calculation and unit price analysis often lead to cost overruns. This paper proposes a standardized parametric approach for estimating the costs of masonry foundations. We integrate geometric volume analysis with Indonesian construction labor standards (AHSP), providing a robust framework for contractors and project managers to calculate project costs efficiently. The study provides mathematical models to optimize resource allocation, specifically tailored to the unique topographical and material supply chain challenges observed in the Balinese construction sector. 1. Introduction In civil engineering projects, the foundation is the first critical cost center. Inaccurate estimation of stone masonry foundations can compromise the entire project budget. Unlike standardized concrete, river stone masonry is labour-intensive and sensitive to material sourcing logistics. This paper bridges the gap between structural design and economic feasibility. 2. Mathematical Volume Estimation The calculation of the budget begins with the volumetric analysis of the trapezoidal foundation profile. The total volume ($V$) in cubic meters ($m^3$) is calculated using the following formula: $$V = \frac{(a + b)}{2} \times t \times L$$ Where: $a$ = Top width of the foundation (meters) $b$ = Bottom width of the foundation (meters) $t$ = Height or depth of the foundation (meters) $L$ = Total length of the foundation (meters) 3. Cost Analysis Framework To determine the total cost ($C_{total}$), one must account for material costs ($C_m$) and labor costs ($C_l$). The unit price analysis (AHSP) includes the standard coefficients for stone, sand, and cement usage. $$C_{total} = V \times (Price_{material} + Price_{labor})$$ Where $Price_{material}$ is the sum of: $$Price_{material} = (k_s \cdot P_s) + (k_c \cdot P_c) + (k_a \cdot P_a)$$ $k$ = Coefficient of material required per $m^3$ $P$ = Market price per unit 4. Optimization and Recommendations To maximize economic efficiency without sacrificing structural integrity, project managers should prioritize local material sourcing and perform bulk procurement. For complex estimation and structural safety certification, professional oversight is recommended.

Versi Bahasa Indonesia Abstrak Estimasi biaya yang presisi, atau Rencana Anggaran Biaya (RAB), adalah fondasi manajemen proyek dalam industri konstruksi. Untuk proyek pondasi batu kali, ketidakakuratan dalam perhitungan volume dan analisis harga satuan sering kali menyebabkan pembengkakan biaya. Makalah ini mengusulkan pendekatan parametrik standar untuk mengestimasi biaya pondasi pasangan batu. Kami mengintegrasikan analisis volume geometris dengan standar tenaga kerja konstruksi Indonesia (AHSP), memberikan kerangka kerja yang kuat bagi kontraktor dan manajer proyek untuk menghitung biaya proyek secara efisien. Studi ini menyediakan model matematis untuk mengoptimalkan alokasi sumber daya, yang disesuaikan secara khusus dengan tantangan topografi dan rantai pasok material yang unik di sektor konstruksi Bali. 1. Pendahuluan Dalam proyek teknik sipil, pondasi adalah pusat biaya kritis pertama. Estimasi yang tidak akurat pada pondasi batu kali dapat membahayakan seluruh anggaran proyek. Berbeda dengan beton standar, pasangan batu kali sangat padat karya dan sensitif terhadap logistik pasokan material. Makalah ini menjembatani kesenjangan antara desain struktural dan kelayakan ekonomi. 2. Estimasi Volume Matematis Perhitungan anggaran dimulai dengan analisis volumetrik profil pondasi trapesium. Volume total ($V$) dalam meter kubik ($m^3$) dihitung menggunakan rumus berikut: $$V = \frac{(a + b)}{2} \times t \times L$$ Dimana: $a$ = Lebar atas pondasi (meter) $b$ = Lebar bawah pondasi (meter) $t$ = Tinggi atau kedalaman pondasi (meter) $L$ = Panjang total pondasi (meter) 3. Kerangka Kerja Analisis Biaya Untuk menentukan biaya total ($C_{total}$), seseorang harus memperhitungkan biaya material ($C_m$) dan biaya tenaga kerja ($C_l$). Analisis Harga Satuan Pekerjaan (AHSP) mencakup koefisien standar untuk penggunaan batu, pasir, dan semen. $$C_{total} = V \times (Price_{material} + Price_{labor})$$ Dimana $Price_{material}$ adalah jumlah dari: $$Price_{material} = (k_s \cdot P_s) + (k_c \cdot P_c) + (k_a \cdot P_a)$$ $k$ = Koefisien material yang dibutuhkan per $m^3$ $P$ = Harga pasar per unit 4. Optimasi dan Rekomendasi Untuk memaksimalkan efisiensi ekonomi tanpa mengorbankan integritas struktural, manajer proyek harus memprioritaskan sumber material lokal dan melakukan pengadaan dalam jumlah besar. Untuk estimasi kompleks dan sertifikasi keselamatan struktural, pengawasan profesional sangat disarankan.
