Population growthis linear tothe requrement of settlement area, while the area of the earth is limited. It was caused inappropriate use of the land. This study aims to identify, analyze, and describe dynamics and suitability of land for settlements in Padang. Determination of land suitablity for settlementis using Multi Criteria Evaluation (MCE) method. The indicators used in determining the suitability of land for settlement is the slope, the frequency of flooding, drainage, distrubusi gravel, rock distribution and effective depth. Weighting in the analysis of land suitability based on the opinions of experts from various fields related to as many as 15 experts. Analysis result for land suitability of settlements in the area show that: there were 12.543 ha (18%) very suitable for settlement; 52.390 ha (75,4%) were suitable for settletment; 4.279 ha (6,2%).were compatible with marginal for settlement; and 285 ha (0,8%) were unsuitable for settlement. The area is very suitable for residential areas is very limited, so expect optimal utilization.

Indonesia is one country that has the potential for development of tourist beach. The number of visits to both domestic and foreign travel has increased every year. This study aims to determine the priority of tourism development in the coastal city of Padang. Priority tourism development is determined by the suitability of land and tourism development potential index. Suitability of land for tourist beach area using eight indicators, namely: water transparency, type of beach, shore depth, substrate, current speed, live coral cover, hazards, and accessibility. Index development potential attraction beach using five criteria: community acceptance, facilities and supporting infrastructure, cultural performances, industry support, and government support. The results showed attraction Muaro peevish beach is the main priority areas of tourism development in the coastal city of Padang, while the beach a tourist attraction Muaro Anai is the lowest priority.

The flood disaster has caused much harm to human life. The Effort to reduce the disadvantages caused by the flood is to develop settlement area priority based natural disaster. The purpose of research to determine the priority zone of settlement development using geography information system method (GIS) with regards to hazard risk. The indicator used in determining of area suitability for the settlement are a slope, flood, drainage, gravel, texture, and effective depth. Meanwhile, the Indicators used to determine of flood hazard zone are kinds of soil, slope, landform, rainfall, elevation, land use, and geology. The result shows that the level of area suitability and flood hazard of Limapuluh Kota district were 46% and 50.6%, respectively, these results are categorized as prone to moderate. The analysis result for priority of settlement area development for Limapuluh Kota district shows that it was suitable for S2 (fourth level priority) and flood hazard to medium. Therefore, in the use of area needs more cost and environmental conservation as disaster mitigation efforts for the future.

In Indonesia the implementation of the spatial plan is only a small part of the plan. The impact of incompatibility with spatial planning is the deterioration of environmental quality. Tanah Datar District has a growth rate of settlements of 0.8 percent/year period 2000-2017. The purpose of this research is to determine index consistency of spatial plan and determination of policy direction of development of settlement area. To determine the consistency index of spatial planning to do a comparison between land use with the spatial plan. Land use map produced from Landsat ETM + 8, and map spatial plans resulting from the RTRW period 2008-2028 In Tanah Datar District. In addition, to determine the direction of the policy of settlement development using the ISM method. The number of elements analyzed by 10 elements, with 24 experts. The results show that around 43,7 percent of settlement development is incompatible with the spatial plan. Therefore, it is necessary for government policy to be consistent with spatial planning and law enforcement on spatial violation

Pagar Alam City is one of the cities in South Sumatera province which has a high number of people who are quite and fluctuating diarrhea caused by poor environmental sanitation. The research aims to produce a direction for the arrangement of a sanitary-based environment for diarrhea prevention in Pagar Alam City. This research is a qualitative study with an analysis of Analytical Hierarchy Process (AHP) which emphasizes comparative judgment based on data and literature study. From interviews and literature studies, there are three important criteria for structuring a sanitation-based environment, namely society, environment, and infrastructure. From these criteria, there are eight alternative policies related to the arrangement of sanitation based environment for diarrhea prevention, with priority as follows: Environment sanitation Program based on a case study, strengthening community empowerment facilitator, improving coordination and cooperation among related agencies, rescue environment through local wisdom, improvement of infrastructure access and sanitation facilities, forming sanitation clinics incorporated in Public health center, institutional strengthening and drafting strict rules, and Monitoring and evaluation of sanitation programs
