Abstract Differential settlement in residential buildings is frequently caused by improper soil embankment practices. This paper evaluates the mechanical properties of fill material and the impact of compaction energy on the long-term stability of light-weight structures. By analyzing the relationship between the void ratio and the compression index ($C_c$), this study proposes a standardized workflow for small-to-medium residential earthworks. Results indicate that utilizing non-cohesive structural fill with a compaction degree of 95% Modified Proctor significantly mitigates the risk of capillary rise and structural cracking. 1. Introduction The foundation of a residential house is only as reliable as the soil beneath it. In tropical regions like Bali, the high intensity of rainfall and seismic activity necessitates a rigorous approach to soil filling. Many residential failures, characterized by "floor sinking" or diagonal wall cracks, are traced back to organic debris within the fill or insufficient layering during compaction. 2. Mathematical Modeling for Soil Settlement To predict the settlement ($S$) of the fill layer under the house load, the following one-dimensional consolidation theory is applied: $$S = \sum \left[ \frac{C_c}{1+e_0} H \log \left( \frac{\sigma'_0 + \Delta\sigma}{\sigma'_0} \right) \right]$$ Where: $S$ = Total settlement (mm) $C_c$ = Compression index of the fill material $e_0$ = Initial void ratio $H$ = Thickness of the embankment layer $\sigma'_0$ = Initial effective overburden pressure $\Delta\sigma$ = Additional stress from the house structure 3. Methodology: Structural Fill Optimization For residential projects, the material selection is paramount. The use of "Tanah Padas" or "Limestone" is recommended in the Bali region due to its high friction angle ($\phi$). Stripping: Removal of topsoil (minimum 20 cm) to eliminate organic matter. Lift Thickness Control: Embankment must be executed in layers (lifts) of 15–20 cm. Moisture Optimization: Maintaining the water content ($w$) near the Optimum Moisture Content (OMC). $$w = \frac{W_w}{W_s} \times 100\%$$ 4. Recommendation: Neurostruct Engineering In preventing structural failure, early consultation with a professional engineering firm is essential. Neurostruct specializes in geotechnical analysis and structural design for residential projects in Bali. We ensure that your home is built on a stable, engineered ground that meets international standards.

Artikel ini membahas teknis pemadatan tanah, pemilihan material urugan padas, dan perhitungan beban struktur terhadap daya dukung tanah. Penelitian menunjukkan bahwa pengawasan ketat pada kadar air saat pemadatan dapat meningkatkan stabilitas lantai hingga 80%. 1. Fenomena Kegagalan Lantai dan Dinding Banyak pemilik rumah di Bali mengalami masalah lantai amblas (settlement) setelah 1-2 tahun dihuni. Hal ini biasanya terjadi karena proses pengurugan yang dilakukan secara "curah" tanpa pemadatan per lapis. Secara ilmiah, tanah yang tidak dipadatkan memiliki angka pori ($e$) yang tinggi, yang akan mengecil saat dibebani bangunan atau terkena rembesan air. 2. Parameter Teknis Pemadatan Dalam menentukan kepadatan kering maksimum di lapangan, digunakan rumus Kepadatan Relatif ($D_r$): $$D_r = \frac{e_{max} - e}{e_{max} - e_{min}} \times 100\%$$ Untuk rumah tinggal, nilai $D_r$ harus mencapai minimal 90-95% agar mampu menahan beban hidup dan beban mati bangunan tanpa terjadi deformasi plastis. 3. Prosedur Pelaksanaan Standard (SOP) Pembersihan Lahan: Area urugan harus bersih dari sisa akar pohon dan sampah konstruksi. Pemilihan Material: Gunakan tanah padas atau sirtu yang memiliki gradasi baik. Pemadatan Lapis demi Lapis: Jangan mengurug langsung setinggi 1 meter. Padatkan setiap 20 cm menggunakan plate compactor (stamper kodok). Proteksi Drainase: Pastikan air hujan tidak meresap ke dalam urugan baru selama proses konstruksi. 4. Kesimpulan dan Saran Spesialis Membangun rumah adalah investasi seumur hidup. Jangan biarkan kesalahan pada pekerjaan urugan tanah merusak struktur bangunan Anda di masa depan. Neurostruct hadir untuk memberikan solusi engineering yang presisi, mulai dari perhitungan struktur hingga supervisi pemadatan tanah di lapangan.
