Since 2007 PNPM Urban realize that poverty is a structural problem and multi-dimensional. In PNPM Urban perspective , the complexity of the various dimensions of poverty -related social , political , economic , and asset . this research aim is to know the Effectiveness of the National Program for Community Empowerment for Infrastructure Development Accelerated. In this research , the authors use an explanatory survey research methods . Selected number of samples in the analysis of the effectiveness of PNPM Urban infrastructure improvements are stakeholders involved in PNPM Urban population in the research area of all stakeholders involved in PNPM Urban in District Marpoyan Damai  , the authors take purposively respondents who meet the criteria and are associated with research. The results showed that increasing road infrastructure with the PNPM Mandiri. The average improvement of road infrastructure after the PNPM Urban amounted to 35.8 %. The average increase in the quality of infrastructure before the PNPM Urban program is only at 4.4 % per year . This indication shows that roads infrastructure and the quality of the road surface to be increased significantly in the presence of the PNPM Urban Marpoyan Damai  in the District . From interviews with relevant stakeholders PNPM Urban, respondents said PNPM Urban was very effective against the improvement of infrastructure in District Marpoyan Damai .

The geological disaster of landslide has occurred in Merangin Village, Kuok Subdistrict, Kampar Regency, Riau Province which located exactly in the national road of Riau - West Sumatra at Km 91. Based on the occurrence of landslide, this research was conducted to study geological structure and engineering geology to determine the main factors causing landslides. Based on measurement of the structural geology found on research area,  there were fractures, faults and fold rocks which having trend of stress N 2380 E,  plunge 60, trending NE-SW direction. Several faults that found was normal faults directing N 2000 E with dip 200 trending from northeast-southwest and reverse fault impinging N 550 E with dip 550, pitch 200 trending to the northeast. Fold structures showing azimuth N 2010 E trending southeast-northwest. From geological engineering analysis, the results of scan line at 6 sites that have RQD value ranges 9.4% - 78.7 % with discontinuity spacing 4 - 20 cm. So,  It can be concluded that the formed structure was influenced by the extensive northeast-southwest tectonic phase, then continued through north-south tectonic phase, and ended by a tectonic period with directing from northeast-southwest. Rock Mass Rating classification showing value 62 – 76,  Which also resulted that rocks in the study area have weathered on the outside but still in good condition (good rock). However, This condition of structure has caused the formation rocks producing weak zone that became one cause of the occurrence of landslides.

Research area is around Tanjung Balik, Koto Baru Sub Base, Lima Puluh Kota District, West Sumatra Province. Located along the highway Km 10-15 Riau – West Sumatra and the coordinate around 00˚08'40 '' LU - 0˚11'20 '' N and 100˚45'20 '' BT - 100˚47'00 '' BT. The purpose of research to identify petrography, microstructure, types of landslides and the geological condition. The methods using polarization microscope, stereography, landslide identification survey and geological mapping. The result of study shows the petrography analysis of lithology of study area are classified into three types of rocks are Feldspathic Greywacke, Lithic Arenite, and Slate. Microstructures trending system show the foliation structure that is relatively Southeast-Northwest. Types of landslide which dominates in the research area are debris avalanche and translational landslide. Geological analysis show some of rock units are classified into two units: Sandstone Unit and Slate Unit. Sandstone Unit spread in the northern part of the study area, while Slate Unit spread in the southern part of the study area. The characteristics of these rocks showed Pematang Formation.

The research area is located in the eastern part of Langgun Island, Langkawi, Malaysia. Several small islands in the area are included in the research scope, including Anak Tikus Island, Anak Berangan Island, Batang Tunggang Cape, and Langgun Cape. Research on karst geomorphology is still very poor in the research area, especially regarding the classification and the history of the formation. The main motivation for this research is to reveal the beauty and uniqueness of the karst morphology of the research area, which is one of the most valuable geological heritages. Chemical weathering caused by surface water and underground water causes the limestone exposed on this island to form an island karst landscape. The karst morphology in Langgun Island is classified into exokarst and endokarst geomorphology. The morphology of exokarst is divided into two, namely negative exokarst and positive exokarst. The negative exokarst geomorphology found in the study area is dolina and uvala. Meanwhile, the morphology of positive exokarst consists of weathering island karst, which is karst resulting from wave erosion (tombolo, sea stumps, abrasion platforms, sea notches), and residual hills (karst tower and karst cone). The endokarst morphology found is the stalactite feature. This research will be able to increase understanding of karst development so that it forms a unique, beautiful morphology and increases the value of tourism potential, especially in the research area to influence tourist to visit.
