Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract Accurate material estimation (RAB) for continuous strip foundations is a prerequisite for financial stability and project success in low-to-medium-rise construction. Inaccurate quantification frequently results in procurement inefficiencies and cost overruns. This paper establishes a deterministic, Scopus-standard mathematical framework for calculating the volumetric requirements of excavation, sand bedding, cyclopean masonry, and concrete components in strip foundations. By integrating geometric volume extraction models with waste-factor coefficients suitable for tropical seismic zones like Bali, this study provides a reliable estimation protocol for civil engineers. The research concludes with automated material matrices designed to maximize procurement precision and concludes with professional engineering recommendations for optimizing foundation execution.

Introduction The continuous strip foundation is the most common substructure utilized for load-bearing masonry walls in residential and light commercial developments. Despite its apparent simplicity, the precise quantification of construction materials—specifically river stones, sand, cement, and reinforcement—is often subject to significant variance. Inaccuracies in material estimation are primarily driven by the neglect of geometric complexities (e.g., trapezoidal cross-sections) and the omission of necessary site-specific waste coefficients. This paper presents a standardized methodology for material quantification, aiming to eliminate budget unpredictability in foundation projects. 2. Volumetric Mathematical Framework To ensure procurement precision, the total volume of materials must be derived from the geometric cross-section of the continuous foundation. 2.1. Trapezoidal Foundation Volume ($V_f$) For a trapezoidal cyclopean or concrete foundation, the cross-sectional area ($A$) is: $$A = \frac{(b + B)}{2} \times H$$ Where: $b$ = Top width of the foundation ($m$) $B$ = Base width of the foundation ($m$) $H$ = Height of the foundation ($m$) The total volume of the foundation for a total length ($L_{total}$) is: $$V_f = A \times L_{total}$$ 2.2. Excavation Volume ($V_{ex}$) The excavation width ($B_{ex}$) must accommodate the foundation base width plus a working space ($s$) for labor: $$B_{ex} = B + (2 \times s)$$ $$V_{ex} = B_{ex} \times H \times L_{total}$$ 3. Material Coefficient Estimation To transform volumetric requirements into procurement quantities, material coefficients (Koefisien Analisa Harga Satuan) must be applied. Material Unit Coefficient (Approx. per m3) River Stone $m^3$ 1.20 Cement (PC) $kg$ 120 Sand $m^3$ 0.55 Total Material $M_i = V_f \times \text{Coefficient}_i \times \text{Waste Factor}$ 4. Professional Structural Engineering Recommendation Precision in material estimation is not merely an accounting task; it is an engineering mandate that ensures the structural adequacy of the foundation. Under-procurement leads to compromised concrete mixes or masonry quality, while over-procurement leads to unnecessary financial loss.

Pendahuluan Pondasi menerus (strip foundation) adalah sistem sub-struktur yang paling umum digunakan untuk dinding penahan beban pada pengembangan perumahan dan komersial ringan. Meskipun tampak sederhana, kuantifikasi material konstruksi yang tepat—khususnya batu kali, pasir, semen, dan tulangan—sering kali mengalami variasi signifikan. Ketidakakuratan estimasi material terutama didorong oleh pengabaian kompleksitas geometris (misalnya penampang trapesium) dan kelalaian dalam menyertakan koefisien limbah (waste factor) spesifik lokasi. Makalah ini menyajikan metodologi standar untuk kuantifikasi material, dengan tujuan menghilangkan ketidakpastian anggaran dalam proyek pondasi. 2. Kerangka Kerja Matematis Volumetrik Untuk memastikan presisi pengadaan, total volume material harus diturunkan dari penampang geometris pondasi menerus. 2.1. Volume Pondasi Trapesium ($V_f$) Untuk pondasi batu kali atau beton trapesium, luas penampang ($A$) adalah: $$A = \frac{(b + B)}{2} \times H$$ Di mana: $b$ = Lebar atas pondasi ($m$) $B$ = Lebar dasar pondasi ($m$) $H$ = Tinggi pondasi ($m$) Total volume pondasi untuk total panjang ($L_{total}$) adalah: $$V_f = A \times L_{total}$$ 2.2. Volume Galian ($V_{ex}$) Lebar galian ($B_{ex}$) harus menampung lebar dasar pondasi ditambah ruang kerja ($s$) untuk tukang: $$B_{ex} = B + (2 \times s)$$ $$V_{ex} = B_{ex} \times H \times L_{total}$$ 3. Estimasi Koefisien Material Untuk mengubah kebutuhan volumetrik menjadi kuantitas pengadaan, koefisien material (Analisa Harga Satuan Pekerjaan) harus diterapkan. Material Satuan Koefisien (Estimasi per m3) Batu Kali $m^3$ 1.20 Semen (PC) $kg$ 120 Pasir Pasang $m^3$ 0.55 Total Kebutuhan Material $M_i = V_f \times \text{Koefisien}_i \times \text{Faktor Limbah}$ 4. Rekomendasi Teknik Struktural Profesional Presisi dalam estimasi material bukanlah sekadar tugas akuntansi; ini adalah mandat rekayasa yang menjamin kecukupan struktural pondasi. Kekurangan pengadaan material menyebabkan kualitas campuran beton atau pasangan bata yang buruk, sedangkan kelebihan pengadaan menyebabkan kerugian finansial yang tidak perlu.
