Abstract

Tujuan penelitian ini dilakukan pengujian untuk mengetahui sifat-sifat fisik (index properties) dari tanah yang berasal dari Dusun Paloh 80, Percut Sei Tuan dan mengetahui perbandingan kuat daya tekan tanah yang dicampur dengan abu cangkang sawit dan semen. Penelitian dilakukan dengan melakukan pengambilan sampel sebanyak 40 sampel tanah dan melakukan uji laboratorium untuk mengetahui nilai index properties dan engineering properties menggunakan uji UCT (Unconfined Compression Test). Dengan tanah asli dan tanah yang sudah distabilisasi menggunakan campuran abu cangkang sawit dan semen dengan persentase 0%, 6%, 12%, 18%, 24%, dan 30% pada kondisi kadar air optimum. Pengujian yang dilakukan berdasarkan metode ASTM. Semakin bertambahnya persentase campuran abu cangkang sawit dan semen, maka nilai koefisien semakin kecil. Hasil penelitian menunjukkan bahwa nilai kuat tekan bebas (qu) pada tanah asli sebesar 0.433 kg/cm2 . Pada variasi campuran 3% ACS + 3% semen, diperoleh nilai kuat tekan tanah (qu) maksimum sebesar 0.585 kg/cm2 . Nilai kuat tekan bebas tanah (qu) meningkat hingga variasi campuran 15% ACS + 15% semen sebesar 2.150 kg/cm2, nilai kuat tekan bebas campuran ACS + Semen masih diatas nilai kuat tekan bebas pada tanah asli.

Abstract

Steel column structures can be used for various types of buildings, various advantages can be obtained when using steel as a building material, but its use cannot be estimated. Each of these elements will bear forces such as moments, normal or latitude, although the percentages differ from one another. Structures that carry normal forces are generally found in columns, both compressive and tensile so that a normal stress occurs. At this time the framework for the column is conventional steel but at this time there are other alternative materials, namely frames made of mild steel. As we know so far that most of the use of mild steel for roof truss construction, technological advances in the field of steel materials, especially mild steel, have been able to produce high quality mild steel, namely with a minimum tensile strength of 550 MPa. (Zincalume). Based on the results of the analysis, there is a critical stress difference in two cross sections with the same size from different types of materials, namely mild steel and conventional steel.
