Methodology Result and Discussion

478 Extracted lineaments from four illumination directions are overlaid to show integrated extracted lineament. This extracted lineament utilized for lineament density and delineation lineament analysis. Figure 4. Extraction Digital Lineament 4.1.2 Lineament density Lineaments density map of lineaments from four directions is produced and shows in figure . Lineament density map is created by counting lines digitally per unit area lengthkm and then plotted in the respective grid centers and contoured. The high density of lineaments are located in the areas indicated as a main structure. igh anomaly lineament density shows by yellow and red contour, with density value ‐ mkm .These lineament may be caused by tectonic activity. These delineation lineaments with the parameter of lineament density are very important for knowing structural geology. 479 Figure 5. extraction digital lineament density 4.1.3 Structural Lineament Delineation lineament resulted structural lineament based on extracted lineament pattern, lineament density anomaly, and linear lower slope. Statistical lineaments are analysis structural lineament trend. Structural lineament maxima were classified by sub drainage area. Structural lineament rose diagram shows dominant lineament trends, these are NW‐SE, WNW‐ESE and NE‐SW. Structural lineament trend NW‐SE shows in Kepahiang sub drainage area C dan D, WNW‐ESE shows in sub drainage area A, and NE‐ SW shows in sub drainage area B.

Base on arding, et al. 8 structural lineament trend NW‐SE is associated with PDZ Principal Displacement Zone of Sumatera fault system, NNW‐SSE trend is associated with en echelon synthetic fault, and NE‐SW trend is associated with en echelon antithetic fault . Figure 7 structural lineament type 4.2 Manifestation Surface geothermal manifestations indicate the existence of active subsurface geothermal system. Geothermal manifestations are commonly associated with geological structures. Several geothermal surface manifestations found, which consist of hot springs, mud pool, fumarole, and solfatara. Manifestation associated with four structural trend, there is NW‐SE trend associated with hot spring in Kelobak, NNW‐SSE trend associated with hot spring, mud pool and fumarole in Kaki Kaba and Air Sempiang, WNW‐ESE trend associated with hot spring in Suban, and structural trend NE‐SW associated with hot spring in Sindang Jati. This structural play is believed to have an important role as discharge zones indicated by geothermal manifestation occurrences. The structural trend is related to tensional regime of Musi and Ketaun segment of Sumatera Fault. 481 Figure 8. geothermal manifestation

5. Conclusion

The extracted lineaments represent linear lineament patterns and distributions. The high densities of lineaments are located in the areas indicated as a main structure. Lineament delineation analysis is utilized to determine the structural geology in the surface study area. Structural plays trending NW‐SE, NNW‐SSE, WNW‐ESE and NE‐SW play an important role as discharge zone. Lineament distributions and patterns are important parameters for permeable zones indicated by geothermal occurrence. The structural trend is believed to be related to the tensional regime of Musi and Ketaun segment of Sumatera fault.

Government and community give attention to exploit it in accordance to potential existing of the region. The problem is low utilization arises multiplier effect, infrastructure concentrated in the industrial area, economic agglomeration problem between industrial and community area, disparities distribution of infrastructure between villages in Minas District. The purpose of this research is develop concepts and strategies for optimalization of infrastructure in the Minas District to exploit multiplier effect of the petroleum and palm oil industry. This study uses facility and utility analysis, identification of industry impact, and scoring analysis. Minas District has function and role as Strategic Economic Zone based on utilization of oil and gas resources. Physical carrying capacity of the area significantly in good condition, support of adequate infrastructure. The potential existence of the industry have a positive impact on the economic and physical development. While the negative impact of industrial produce pollution of water, soil and air. Spillovers from industrial activity is concentrated in several areas in direct contact to the industry area. Analysis of scoring against infrastructure priorities shows that drainage and water supply is the main priority in the area, roads at second priority and the third priority is electricity. Based on analysis, development concept of Minas District is infrastructure optimalization of petroleum and palm oil industry activities.

1. Introduction

Minas District has potential prospective industrial area in Siak. nternational petroleum industry Chevron Pacific ndonesia is one of the major industries located in Minas District, and the spread of palm oil plantations nationwide along with its processing plant is also located in this region. n addition, Minas District has a very strategic location, is the gateway Pekanbaru‐Medan so that the development of trade and services sector is also growing rapidly. The effects of these industrial activities influence for Minas District itself and the surrounding community, especially the growth of economic activities. The effect given by industry is expected to provide the major impetus for the growth of Minas District in social, economic, and physical.
