Abstract

Riset ini didasari oleh adanya anomali di tingkat pertumbuhan perbankan Syariah, yang awalnya dicanangkan pada dekade pertama berkisar 3,5%--5% tetapi hingga dekade terakhir stagnan di angka 5%. Penelitian ini ingin mengkaji lebih jauh minat masyarakat untuk menggunakan perbankan Syariah dengan menggunakan pendekatan Theory of Reasoned Action. Penelitian ini merupakan penelitian kuantitatif yang berusaha menemukan hubungan sebab akibat (causality) antara Variabel Sikap Terhadap Keperilakuan dan Norma Subyektif dengan Minat menggunakan Perbankan Syariah. Data diperoleh dengan menyebarkan 200 kuesiner di Kota Palembang. Analisis yang digunakan adalah analisis Structural Equation Modeling (SEM). Hasil penelitian menunjukkan bahwa sikap terhadap keperilakuan (attitude toward behavior/ATB) berhubungan positif dengan minat menggunakan produk perbankan syariah. Hal tersebut disimpulkan berdasarkan nilai probability yang menunjukkan nilai 0.000 (lebih kecil dari 0.05) dan C.R = 3,810 (lebih besar dari 1.96). Norma Subyektif berpengaruh secara negatif dan signifikan terhadap Minat. Hal tersebut disimpulkan berdasarkan nilai probability yang menunjukkan nilai 0.048 (lebih kecil dari 0.05) dan C.R = -1,980 (lebih kecil dari 1.96). Sikap terhadap Keperilakuan tidak berpengaruh secara positif dan signifikan terhadap Norma Subyektif. Hal tersebut disimpulkan berdasarkan nilai probability yang menunjukkan nilai 0.423 (lebih besar dari 0.05) dan C.R = 0,801 (lebih kecil dari 1.96). Minat berpengaruh secara positif dan signifikan terhadap Penerimaan perbankan Syariah. Hal tersebut disimpulkan berdasarkan nilai probability yang menunjukkan nilai 0.000 (lebih kecil dari 0.05) dan C.R = 5,651 (lebih besar dari 1.96).

Abstract

Introduction: Research has been carried out titled "Determining the Volume of Liquefaction Sediment Using the Geoelectric Resistivity Type Method in Balaroa Village". Methods: This research aims to identify subsurface lithology and determine the volume of liquefaction sediment in Balaroa Village. This research uses the resistivity method Wenner configuration. Result and Discussion: Measurements were carried out in 4 passes with the distance between electrodes on Tracks 1 - 3 being 7 m and on Track 4 a distance of 10 m. From the results of measurements and data interpretation, it was obtained that the type resistance value was 2.98 - 436.14 Ωm with lithology in the form of clay, sand, and gravel. The calculated volume of liquefaction sediment in Balaroa Village is 370,883 m³. Conclusion: Clay and sand rocks are liquefaction sediments with resistance values of less than 67.86 Ωm. Meanwhile, gravel and building debris are non-liquefaction rocks with resistance values of more than 67.86 Ωm. The calculated liquefaction sediment in Balaroa Village is around 370,883 m³. The volume of liquefaction sediment increases in thickness in the eastern part, which is caused by morphological conditions that tend to be more gentle in that part.

Abstract

Introduction: Aquifer layers have been identified in the oil palm plantation area of PT Unggul Widya Teknologi Lestari Pasangkayu Regency. This study aims to determine the lithology of subsurface rocks and the depth of the aquifer layer as a source of clean water in the study area. Method: This study uses the geoelectric method of type resistance with Wenner configuration, with the number of electrodes 24 rods and a spacing of 10 meters. 2D cross-sectional model using Res2Dinv software program. Results and Discussion: Based on the value of the type resistance of the subsurface constituent rock lithology at the research site is interpreted to consist of three layers, namely clay with a specific resistance value < 29.15 Ωm, sand and sandy clay with a specific resistance value of 29.15 Ωm to 72.89 Ωm, and conglomerate with a specific resistance value > 72.89 Ωm. The aquifer layer is interpreted with a specific resistance value of 29.15 Ωm to 72.89 Ωm. The aquifer layer is detected to spread from the northeast to the southwest of the research site with a depth of ±25-39 m. Conclusion: In the oil palm plantation of PT Unggul Widya Teknologi Lestari, the subsurface layer consists of clay (1.98 Ωm - 29.15 Ωm), sand and passive clay (29.15 Ωm - 72.89 Ωm), and conglomerate (72.89 Ωm - 1120.5 Ωm). Thin aquifers, with a thickness of 5-10 m and depth of 25-39 m, are detected in the sand and sandy clay layers.
