In regions with problematic soil conditions, such as the alluvial plains often encountered in Bali, proper geotextile installation is critical to prevent subgrade failure and ensure structural longevity. This paper evaluates the mechanical principles governing geosynthetic performance and establishes a rigorous field installation protocol to maximize engineering outcomes. 1. Introduction Geotextiles, both woven and non-woven, are synthetic fabrics that provide cost-effective solutions for soil instability. By preventing the intermixing of distinct soil layers and providing tensile reinforcement, they significantly improve the Load Bearing Capacity (LBC) of roads, embankments, and drainage systems. However, the efficacy of these materials is entirely dependent on the precision of their installation. 2. Mechanical Principles of Geosynthetic Reinforcement The function of a geotextile in subgrade stabilization is governed by the ability to distribute vertical stresses ($P_v$) over a wider area, thereby reducing the stress intensity on the soft subsoil. The Reinforcement Mechanism: The required tensile strength ($T_r$) of the geotextile to support a design load can be approximated by: T_r = (P * delta * K) / (2 * tan(phi)) Where: P = Applied pressure on the subgrade delta = Soil-geotextile friction angle K = Earth pressure coefficient phi = Internal friction angle of the soil 3. Installation Methodology To achieve maximum engineering performance, the following protocol must be strictly observed: 3.1 Site Preparation Clear the area of vegetation, sharp objects, and large boulders. The subgrade must be leveled to the design gradient. If the soil is excessively soft, perform a proof roll to identify weak spots. 3.2 Geotextile Unrolling The geotextile must be unrolled in the direction of the traffic flow or the primary stress direction. Avoid dragging the material over sharp debris. 3.3 Overlapping (Splicing) Overlapping is essential to maintain structural continuity. The width of the overlap depends on the California Bearing Ratio (CBR) of the subgrade: CBR > 3%: Overlap 300 mm CBR 1–3%: Overlap 600 mm CBR < 1%: Overlap 900 mm – 1000 mm 3.4 Tensioning and Backfilling Tension the geotextile to remove wrinkles before placing aggregate. When backfilling, maintain a minimum dump height of 150 mm to prevent equipment damage. Compaction should proceed in layers, avoiding heavy equipment directly on the exposed geotextile. 4. Quality Control Engineering supervision must verify: Integrity of seams (if stitched). No "ballooning" or tearing during compaction. Correct orientation of the fabric properties (machine direction). 5. Conclusion Geotextile installation is a high-precision task. Adherence to the specified overlap widths and material handling guidelines ensures that the geosynthetic acts as a true structural component rather than a failed barrier. PART 2: BAHASA INDONESIA TECHNICAL PAPER Abstrak Pemasangan geotextile pada pekerjaan tanah adalah praktik fundamental dalam teknik geoteknik modern, yang berfungsi sebagai pemisah (separation), penguat (reinforcement), filtrasi, dan drainase. Di wilayah dengan kondisi tanah bermasalah, seperti dataran aluvial yang sering dijumpai di Bali, pemasangan geotextile yang tepat sangat krusial untuk mencegah kegagalan tanah dasar dan menjamin usia pakai struktur. Makalah ini mengevaluasi prinsip mekanis performa geosintetik dan menetapkan protokol pemasangan lapangan yang ketat untuk memaksimalkan hasil rekayasa. 1. Pendahuluan Geotextile, baik jenis woven maupun non-woven , adalah kain sintetis yang memberikan solusi ekonomis untuk ketidakstabilan tanah. Dengan mencegah percampuran lapisan tanah yang berbeda dan memberikan penguatan tarik, material ini secara signifikan meningkatkan kapasitas dukung ( Load Bearing Capacity ) jalan, timbunan, dan sistem drainase. Namun, efikasi material ini sangat bergantung pada ketepatan pemasangannya. 2. Prinsip Mekanis Penguatan Geosintetik Fungsi geotextile dalam stabilisasi tanah dasar diatur oleh kemampuannya untuk mendistribusikan beban vertikal ($P_v$) ke area yang lebih luas, sehingga mengurangi intensitas tegangan pada tanah lunak di bawahnya. Mekanisme Penguatan: Kekuatan tarik yang dibutuhkan ($T_r$) dari geotextile untuk mendukung beban desain dapat didekati dengan: T_r = (P * delta * K) / (2 * tan(phi)) Keterangan: P = Tekanan beban pada tanah dasar delta = Sudut geser tanah-geotextile K = Koefisien tekanan tanah phi = Sudut geser dalam tanah 3. Metodologi Pemasangan Untuk mencapai performa rekayasa maksimum, protokol berikut wajib dipatuhi: 3.1 Persiapan Lokasi Bersihkan area dari vegetasi, benda tajam, dan batuan besar. Tanah dasar harus diratakan sesuai kemiringan desain. Jika tanah terlalu lunak, lakukan proof roll untuk mengidentifikasi titik lemah. 3.2 Penggelaran Geotextile Geotextile harus digelar searah dengan aliran lalu lintas atau arah tegangan utama. Hindari menyeret material di atas puing-puing tajam. 3.3 Tumpang Tindih (Overlap) Overlap sangat penting untuk menjaga kontinuitas struktural. Lebar tumpang tindih tergantung pada nilai CBR tanah dasar: CBR > 3%: Overlap 300 mm CBR 1–3%: Overlap 600 mm CBR < 1%: Overlap 900 mm – 1000 mm 3.4 Penegangan dan Penimbunan Tegangkan geotextile untuk menghilangkan kerutan sebelum menaruh agregat. Saat menimbun, jaga tinggi tumpahan minimal 150 mm untuk menghindari kerusakan oleh alat berat. Pemadatan harus dilakukan selapis demi selapis, hindari alat berat langsung di atas geotextile yang terbuka. 4. Pengendalian Mutu Pengawasan teknik harus memverifikasi: Integritas sambungan (jika dijahit). Tidak ada sobekan atau "gelembung" saat pemadatan. Orientasi properti kain (arah mesin) yang benar. 5. Kesimpulan Pemasangan geotextile adalah pekerjaan presisi tinggi. Kepatuhan terhadap lebar overlap dan pedoman penanganan material memastikan geosintetik bertindak sebagai komponen struktural yang nyata, bukan sekadar pembatas yang gagal. Neurostruct Professional Recommendations Kesalahan pemasangan geotextile—seperti overlap yang kurang atau prosedur pemadatan yang salah—dapat menyebabkan kegagalan struktur tanah yang fatal dan biaya perbaikan yang besar. Jangan ambil risiko pada pondasi proyek Anda.
