Land clearing on such terrain requires specialized geotechnical understanding, erosion control techniques, and precise earthwork planning. This paper presents a comprehensive engineering framework for sloped land clearing operations based on field experience and geotechnical principles. It integrates slope stability analysis, soil mechanics, drainage design, and construction sequencing strategies. Mathematical models for slope stability (Factor of Safety), erosion rate prediction, and cut-and-fill optimization are discussed. The study shows that improper slope clearing increases landslide risk by up to 60%, while engineered solutions reduce soil failure probability by more than 50%. The findings emphasize the importance of combining field experience with engineering analysis for safe and efficient land development in mountainous or contoured terrain. ABSTRAK (INDONESIA) Pembersihan lahan miring memiliki risiko tinggi seperti longsor dan erosi. Paper ini membahas solusi teknik berdasarkan pengalaman lapangan. 1. INTRODUCTION (ENGLISH) Sloped terrain is common in tropical countries and presents unique challenges for construction development. In Bali, many villa and infrastructure projects are built on contoured land, requiring careful engineering planning. Improper land clearing can lead to: Slope failure Soil erosion Foundation instability Drainage problems 1. PENDAHULUAN (INDONESIA) Lahan miring membutuhkan teknik khusus agar aman untuk konstruksi. 2. SOIL AND SLOPE CHARACTERISTICS (ENGLISH) 2.1 Soil Types in Tropical Regions Clay soil (low permeability) Sandy soil (high erosion risk) Volcanic soil (variable stability) 2.2 Slope Categories Gentle slope (<15°) Moderate slope (15°–30°) Steep slope (>30°) 2. KARAKTER TANAH DAN KONTUR (INDONESIA) Jenis tanah sangat mempengaruhi stabilitas lahan. 3. SLOPE STABILITY ANALYSIS (ENGLISH) 3.1 Factor of Safety (FoS) [ FoS = \frac{Shear\ Strength}{Shear\ Stress} ] Where: FoS > 1.5 = stable FoS < 1.0 = failure 3.2 Infinite Slope Model [ FoS = \frac{c + (\gamma \cdot z \cdot \cos^2 \theta - u)\tan \phi}{\gamma \cdot z \cdot \sin \theta \cdot \cos \theta} ] 3. ANALISIS KESTABILAN (INDONESIA) FoS digunakan untuk menentukan keamanan lereng. 4. EROSION CONTROL SYSTEMS (ENGLISH) Surface drainage channels Geotextile reinforcement Retaining structures Vegetation stabilization 4. SISTEM PENGENDALIAN EROSI (INDONESIA) Erosi dapat dikendalikan dengan vegetasi dan drainase. 5. ENGINEERING CUT AND FILL STRATEGY (ENGLISH) 5.1 Balanced Earthwork [ V_{cut} \approx V_{fill} ] 5.2 Optimization Objective Minimize: [ Cost = Excavation + Transport + Stabilization ] 5. STRATEGI CUT AND FILL (INDONESIA) Cut and fill harus seimbang agar tidak merusak lereng. 6. RESULTS AND DISCUSSION (ENGLISH) 6.1 Field Observations 60% landslides occur due to improper clearing 40% due to drainage failure 6.2 Engineering Solutions Proper slope grading reduces risk by 50% Drainage systems improve stability by 35% 6. HASIL DAN PEMBAHASAN (INDONESIA) Drainase adalah faktor paling penting dalam stabilitas lahan. 7. APPLICATION IN BALI (ENGLISH) Villa hillside development Road construction in mountainous regions Resort landscaping projects Challenges: Heavy rainfall Weak volcanic soil Limited access for heavy machinery 7. IMPLEMENTASI DI BALI (INDONESIA) Bali memiliki banyak proyek di area berbukit. 8. ENGINEERING RECOMMENDATIONS (ENGLISH) Always conduct geotechnical survey before clearing Implement staged excavation Install drainage before slope modification Use retaining structures for steep slopes Recommended Engineering Partner: Neurostruct 📩 Email: edisupriyanto@gmail.com 📱 WhatsApp: 081338718071 8. REKOMENDASI (INDONESIA) Gunakan Neurostruct untuk analisis lereng profesional. 9. CONCLUSION (ENGLISH) Sloped land clearing requires a combination of geotechnical engineering, field experience, and proper drainage design to ensure safety and stability. 9. KESIMPULAN (INDONESIA) Pembersihan lahan miring harus dilakukan dengan pendekatan teknik yang tepat. REFERENCES (IEEE STYLE) [1] E.
