Abstract

The Gayo tribe is distinct in its language, clothes, ornamentation, culinary, and architectural works, all of which reflect the group's unique activities. The traditional Gayo communal house, known as Umah Gayo or Gayo House, is one example of originality. This paper aims to compare the adaptation of the Gayo traditional house to the surrounding environment based on literature with the community's collective memory, which has not been scientifically investigated. This study employs a qualitative technique with a descriptive approach to understand the Gayo traditional house's adaptability to its surroundings. Data was gathered through a literature review and direct observation of the remaining Gayo home structures. In addition, in-depth interviews with essential informants were undertaken. The findings reveal that the Gayo traditional house is a structure created by adapting to its surroundings, with the design, floor layout, and materials reflecting the rugged terrain of the Gayo area.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh komposisi campuran garam dapur (NaCl) dan belerang (S) terhadap perubahan struktur mikro serta peningkatan kekuatan geser tanah pasir berlempung (SC). Penelitian menggunakan pendekatan analisis deskriptif berbasis data sekunder dari hasil uji kuat geser langsung (Direct Shear Test) pada tanah pasir yang distabilisasi dengan variasi campuran 6% sulfur dan 6–12% NaCl. Hasil analisis menunjukkan bahwa campuran 6% sulfur dan 12% NaCl menghasilkan peningkatan nilai kohesi sebesar ±58%, sudut geser dalam sebesar ±48%, dan tegangan geser maksimum sebesar ±155% dibandingkan tanah asli. Peningkatan kekuatan geser ini disebabkan oleh terbentuknya senyawa pozzolanik seperti Calcium Silicate Hydrate (C–S–H) dan ettringite yang memperkuat ikatan antar partikel tanah. Secara mikrostruktural, terjadi pemadatan partikel, penurunan porositas, serta peningkatan interlocking akibat interaksi ionik antara Na⁺, Cl⁻, dan SO₄²⁻ dengan mineral tanah. Hasil penelitian ini menunjukkan bahwa kombinasi NaCl dan sulfur dapat berfungsi sebagai bahan stabilisasi kimia efektif yang mampu meningkatkan kekuatan mekanik dan kestabilan mikrostruktur tanah pasir secara signifikan. Penelitian ini diharapkan dapat menjadi dasar pengembangan teknologi stabilisasi tanah berbasis reaksi kimia alami yang ramah lingkungan dan ekonomis.
