Abstract

Perkembangan teknologi kelistrikan saat ini sangatlah pesat, hal ini sejalan dengan berkembangnya teknologi peralatan pendukung konsumen baik untuk bidang industri maupun rumah tangga. Perancanganan yang matang dibutuhkan untuk sistem instalasi listrik bangunan agar dapat memberikan suplai listrik ke beban listrik sesuai kebutuhan. Selain itu mampu mengatasi gangguan yang terjadi pada beban listrik, peralatan listrik dan melindungi konsumen yang berperan sebagai operator dari kemungkinan bahaya yang terjadi. Untuk mendapatkan sistem instalasi listrik yang baik diperlukan perancangan yang memperhatikan kebutuhan daya listriknya, ukuran kabel penghantar yang digunakan, besar pengaman yang dibutuhkan, jatuh tegangan, kemungkinan besar arus hubung singkat yang akan terjadi, dan lain sebagainya. Error checking yang bertahap pada perhitungan manual dapat dipermudah dengan bantuan sebuah software. Dalam hal ini penulis merancang instalasi listrik Pasar Klewer Surakarta menggunakan bantuan software SIMARIS dengan tujuan membandingkan hasil analisis SIMARIS dengan hasil perhitungan manual. Hasil perbandingan tersebut  menunjukkan bahwa software SIMARIS dapat digunakan dalam sebuah perancangan bangunan dengan jatuh tegangan dibawah 4%.

Abstract

The Lubuksikaping area is located between the main fault branching of the Sumateran Fault so it can be seen that there are many quite complex structures. This research was conducted to determine the structure pattern of the high (horst) and low (graben) that formed in the sub-surface of the Lubuksikaping area, West Sumatera. This research uses gravity data which will then be carried out by spectral analysis, upward continuation, separation of regional and residual anomalies, and Second Vertical Derivative (SVD) analysis. Furthermore, 2D forward modeling is carried out to determine the correlation between the 2D subsurface forward modeling and the resulting SVD graph. Based on the analysis of the regional anomaly map, it can be seen that the measured low anomaly is due to the area in the form of a structural valley formed due to the activity of the Sumatera Fault, while the high is thought to be a structural hill (horst) that forms an elongated mountain range and separated by graben. In addition, based on the analysis of the residual anomaly map, it can be seen that the low anomaly indicates the presence of a depositor (graben), whereas, the high anomaly is indicated as the presence of rocks with high-density contrast values. and is interpreted as a horst structure. Based on the analysis of the horst and graben patterns in the residual Bouguer anomaly, it can be seen that there is an elevation zone (horst) that are northwest and northeast on the residual map and it is known that there are 3 graben structures in Lubuksikaping, namely Panyabungan Graben, Rao Graben and Sumpur Graben with relative northwest-southeast direction. The 2D models of paths A-A' and B-B' show faults that are located relatively the same as the SVD graph obtained from the residual SVD anomaly map.
