Abstract

Kegagalan suatu lereng dapat dikaitkan dengan beberapa faktor seperti keadaan cuaca, jenis tanah, sudut lereng, topografi, atau gabungan faktor-faktor ini. Pada lereng yang bersudut kritis, jenis tanah berbatuan kurang padat dan ketinggian bukit dapat menyebabkan stabilitas tanah berkurang. Akar vegetasi memiliki peranan penting dalam meningkatkan stabilitas struktur tanah dan pergerakan tanah. Tujuan penelitian adalah mengidentifikasi nilai gaya cabut akar maksimum (Fmaks) berdasarkan beberapa jenis vegetasi yang menghasilkan kohesi tambahan sebagai kontribusi kekuatan geser terhadap stabilitas lereng. Jenis vegetasi yang diteliti yaitu Melastomamalabathri Cum , Lantana, Ceanothus Velutinus, Caliandra Calothyrsus dan Tsuga heterophylla. Pengujian gaya cabut akar vegetasi dilakukan pada lereng yang ditumbuhi oleh ke lima vegetasi tersebut. Sebuah tripod dilengkapi dengan strain gauge sebagai instrumen pencatat. Pengujian tersebut dikelompokan berdasarkan kecil, sedang, besar per tiap jenis vegetasi dengan mengamati lebar, panjang dan diameter akar. Metode pengujian ini dilakukan dalam kondisi jenuh tanah. Hasil gaya cabut akar terhadap jenis vegetasi didapatkan Caliandra Calothyrsus menghasilkan gaya cabut akar terbesar (Fmaks) yaitu 0,789 kN dengan diameter 11, 667 mm. Sedangkan pada jenis vegetasi Tsuga heterophylla menghasilkan gaya cabut akar (Fmaks) yaitu 0,533 kN dengan diameter 15,333 mm. Ini menunjukkan bahwa bentuk morfologi akar mempengaruhi besarnya gaya cabut akar maksimum (Fmaks). Kontribusi kohesi akibat interaksi akar-tanah kepada kekuatan geser tanah dapat meningkatkan stabilitas lereng.

Abstract This study was aimed to find out the relationship of body exercise toward the traditional dance major Study Result ondrama, music, and dance art Students 2107 in Padang State University.Type of the research was quantitative with correlational method. The population in this research were students of drama, music, and dance art2017 in Padang State University who were amounted 119students, meanwhile the sample were 41 students. Instruments which used by using observation, documentation and interviews. Types of data used in this research were primary and secondary data. Technique of data analysis was a correlational statistic of product moment.Results of this research showed that there was a relationship ofbody exercise toward the study results of traditional dance of Minangkabau. Value of rarithmetic 0.591 and rtable. 0.312 at significant levels of 5%, then it could be inferred thatrarithmeticwas bigger  than rtable so that the hypothesis of Ho was denied and Ha was received, it meant that there was a significant relationship ofthe body exercise toward the results of Minangkabau traditional dance learning. By using free degree n-2 (41-2 = 39) and the real degree 0.05 on t distribution table to the hypothesis test of significance limit (ttabel) was 1.68. Remind of tarithmetic (4.576) wasbigger than ttable (1.68), then it could be inferred that H0 was rejected and H1 was accepted because the test results proved that tarithmeticwasbigger than ttable i.e. 4.576 > 1.68, this meant there was a significant relationship of the body exercise toward the study results of traditional dance majors on drama, music, and dance artstudent 2017, the relationship was pretty strong on the interpretation. This study also expressed the magnitude of the contribution of a given variable X (the body exercise) toward the variable Y (Minangkabau traditional dance learning results), itwas amounted to 34.93% toward the variable Y and the rest (65.07%) were affected by other factors which not examined in this study. Keywords: The Relationship, Body Exercise, Minangkabau Traditional Dance.
