Abstract

Abstract Soft clay deposits often cause excessive settlement and instability in road embankments. This study investigates ground improvement using prefabricated vertical drains under staged embankment loading through finite element modeling in PLAXIS 2D. The analysis examines consolidation rate, settlement, pore water pressure dissipation, and safety performance for square and triangular drain layouts with spacings of 1.25 m and 1.50 m. Results show that vertical drains accelerate consolidation, reducing the time to reach 90 percent settlement from 8.3 years to less than 3 years, while improving overall embankment stability. The triangular 1.25 m configuration produced the most uniform deformation and fastest consolidation response. The study confirms that optimized drain geometry significantly enhances soft ground performance and provides a practical numerical framework for design applications in tropical regions.

Abstract

Kelompok Usaha Kenje Bersinar yang merupakan produsen minyak goreng kelapa organik di Desa Kenje, Polewali Mandar, menghadapi permasalahan pemasaran yang masih terbatas dari mulut ke mulut dan produk yang belum memiliki merek. Kemasan produk belum terstandarisasi karena menggunakan botol plastik bekas dan jerigen, sehingga aspek sanitasi kurang diperhatikan dan tidak memiliki variasi ukuran. Selain itu, produk belum memiliki sertifikat halal dan izin Produksi Pangan Industri Rumah Tangga (PIRT) yang penting sebagai jaminan kualitas bagi pelanggan. Tujuan pengabdian ini adalah untuk membantu mitra melakukan diversifikasi kemasan, memberikan pelatihan pemasaran, dan mengembangkan kios digital berbasis web untuk memperluas jangkauan pasar. Metode pelaksanaan kegiatan ini terdiri dari beberapa tahapan, meliputi sosialisasi, pelatihan, pengembangan teknologi, pendampingan, serta monitoring dan evaluasi. Hasil dari program ini adalah terciptanya empat kemasan baru yang lebih steril dan sesuai standar pasar, yaitu kemasan gelas plastik 220 ml, standing pouch 500 ml, botol plastik 1000 ml, dan jerigen 1 liter. Sebuah kios digital berbasis web juga berhasil dikembangkan untuk menampilkan produk dan memfasilitasi pemesanan secara real-time yang terintegrasi dengan WhatsApp. Kegiatan pengabdian ini berhasil memberikan nilai tambah serta meningkatkan daya saing produk di pasaran.

Abstract

This study aims to formulate an effective airside infrastructure development strategy at Tampa Padang Airport (Class II Airport, Category 4C) to attract new airlines and support the economic potential of West Sulawesi. Using a qualitative descriptive method with SWOT analysis (IFAS and EFAS matrices) as the main strategic analysis tool, the results show that the airport is internally in a strong position (IFAS score: 3.68), supported by qualified human resources and adequate apron capacity. However, several critical weaknesses remain, namely the limited Taxiway Light System, the absence of a Precision Navigation System (ILS/PBN), and a PCN value that restricts larger or heavier aircraft. Externally, the airport is in a very favorable position (EFAS score: 3.91), driven by the potential recovery of the air transport market (LLAU) and strong tourism potential. The biggest threat is the difficulty of land acquisition for runway extension. The most effective development approach is an intensive strategy (SO strategy). Key recommendations include: (1) increasing the PCN and runway pavement strength to accommodate Code 4 aircraft (B737 series); (2) total rehabilitation of the Taxiway Light System and installation of ILS/PBN; and (3) acceleration of land acquisition to realize runway extension in accordance with the Master Plan.
