This study aimed to analyze and to map the ability of agricultural land in East Lombok Regency West Nusa Tenggara Province using Geographic Information System (GIS). The method used in this research is descriptive to analyze and match data on the condition of the study area with the criteria for land capability class refer to the Minister of Environment Regulation No.17 of 2009. The parameters observed were soil texture, slope, drainage, effective depth, erosion, and flood threat. The results showed that East Lombok Regency was included in 6th land capability classes, namely class II, III, IV, VI, VII and VIII. Land with class IV dominates the research area is 501.04 km2 which is spread almost in all districts in East Lombok Regency. Areas with class II, III, and IV land are the land that can be used for agricultural cultivation, while class VI, VII, and VIII land is the land with heavy inhibitor factors, so it is better left in natural conditions.

The research area was conducted within the Bukit Persekutuan, Kuala Lumpur, and it was located at the latitude 3° 8'32.93"N and longitude 101°40'32.80"E. The researcher carried out geological terrain mapping to evaluate the research area in accordance with the geological terrain classification attributes of each thematic map produced, namely, Terrain map, slope gradient map, erosion, and instability map, as well as construction suitability map. The occurrence of landslide events within the research area becomes a major contributing factor to thoroughly conducting an investigation by field mapping and analysing using the Geographic Information System (GIS) technology. The application of Geographic Information System (GIS) and drone photogrammetry images play an essential role to analyze and process the data, thus, generate the thematic maps. The research area indicates that about 79.11% of the overall area was not appreciable with erosion, 8.58% contribute to the erosion, 11.00% of recent general instability, and 2.97% represent a landslide event. The suitability for development mapping illustrated Class I (23.40), Class II (36.37%), Class III (26.39%), and Class IV (15.50%) where it can be referred to the construction suitability classification system, the suitability for development was high in class I, moderate in class II, low in class III and not suitable in class IV.

This research is aiming at the changing land use from agricultural land to photovoltaic power plant. Geographic information system (GIS) technology was used to indicate the unsuitable areas for five economic crops that are paddy, sugar cane, maize, cassava and para rubber. The assess cost, income, and CO2 emission of the economic crops and photovoltaic power plant are the major factors for the unsuitable agricultural land deciding that will be changed to build photovoltaic power plant. The results found that the unsuitable areas for the 5 economic crops are 241,142 rai and the average solar irradiance is 17.6 MJ/m2.day for this areas which is suitable to build the photovoltaic power plant. The profit/losing of paddy, sugar cane, maize, cassava and para rubber in the suitable areas are-1,193 baht/ton, 33 baht/ton, 85 baht/ton, 259 baht/ton and-9,150 baht/ton, respectively while photovoltaic power plant cost and income are 4.12 baht/kWh and 5.65 baht/kWh respectively. CO2 emission of paddy, sugar cane, maize, cassava, para rubber and photovoltaic power plant are 2,315 kgCO2eq/tonpaddy, 37.15 kgCO2eq/ton, 256.12 kgCO2eq/ton, 29.07 kgCO2eq/ton, 153 kgCO2eq/ton and-0.5743 kgCO2eq/kWh, respectively. From these results, land use changing from economic crops planting in unsuitable areas to build photovoltaic power plant is appropriate and worth in the environmental and the economic aspect.

Abstrak: Bencana banjir merupakan bencana yang sering terjadi di wilayah iklim tropis khususnya daerah yang letaknya dikelilingi oleh aliran air atau genangan air seperti danau. Banjir di Indonesia dipengaruhi oleh pergantian musim yang tidak menentu yang menyebabkan bencana banjir. Penelitian ini bertujuan untuk memetakan wilayah yang rawan terhadap banjir dan mengetahui sebarapa besar tingkat kerawananan banjir yang dapat terjadi di studi area penelitian pada wilayah Kabupaten Semarang. Penelitian ini menggunakan metode overlay dengan tumpang susun layer, berdasarkan hasil perhitungan total scoring dari nilai dan bobot dari tiap parameter. Pengumpulan data dilakukan dengan mengumpulkan data sekunder berupa data spasial dan non spasial dari lembaga resmi Negara Indonesia, yang dipakai untuk mendukung analisis yang dilakukan. Dari hasil analisis yang dilakukan pada studi area penelitian di wilayah Kabupaten Semarang, diketahui terdapat 159 desa pada daerah dengan tingkat kerawanan yang rendah, serta 109 desa pada daerah dengan tingkat kerawanan sedang, sisanya 20 desa berada pada tingkat kerawanan tinggi. Dari analisis yang dilakukan, dapat ditarik kesimpulan bahwa wilayah Kabupaten Semarang khususnya pada daerah studi area penelitian menghasilkan informasi dari empat kecamatan yang ada, memiliki tingkat kerentanan yang didominasi oleh tingkat tidak rawan dan cukup rawan. Kata kunci: Bencana Banjir, Overlay, Scoring, Sistem Informasi Geografi.Abstract: Disaster flood disasters that occur in climatic areas, especially areas associated with water flows or puddles such as lakes. Floods in Indonesia are inspired by the changing seasons that are disastrous floods. This study aims to map the areas that are prone to flooding and how much danger is the level of flood vulnerability that can occur in the study area of Semarang Regency. This study uses an overlay method with overlapping layers, based on the calculation of the total score of the values and weights of each parameter. Data collection was carried out by collecting secondary data in the form of spatial data and non-official Indonesian institutions, which were used to support the analysis carried out. From the results of the analysis carried out in the study area of research in Semarang Regency, it is known that there are 159 villages in areas with low levels of vulnerability, as well as 109 villages in areas with moderate levels of vulnerability, the remaining 20 villages are at high levels of vulnerability. From the analysis carried out, it can be concluded that the Semarang Regency area, especially in the study area the research area produces information from the four existing sub-districts, has a level of vulnerability which is dominated by a level of vulnerability which is not vulnerable and quite vulnerable. Keywords: Flood Disaster, Overlay, Scoring, Geographic Information System.

This research was conducted in the northeastern slopes of Mount Agung in Karangasem regency, Bali province. The research area is dry land with land use patterns that have not demonstrated compliance with existing land potential. On the other hand, technological advances in the field of agriculture has been growing rapidly, one by analyzing the ability of the land to determine the potential of land resources and minimize the risk of failure of farmers. The results of the analysis of land capability is expected to serve as guidelines in a more optimal use of land in accordance with expectations. The purpose of this study was to determine the potential of land and recommends referral based land use conditions existing land capability in the area of research. The design used is descriptive design, with the main objective to provide a picture or description of land use capability and suitability of the study area. Guidelines for land capability analysis in this study refers to Arsyad (2006) and the Regulation of the Minister of Environment No. 17 Year 2009 on Guidelines for Determining Environmental Carrying Capacity in Regional Spatial Planning. The results showed that 1) land capability class research in areas ranging from class III to class VI. Land capability class III is spread on the land unit 1, land unit 2, land unit 3,and land unit 8. Capability class IV land located on land unit 4, land unit 7, land unit 9, land unit 10 and land unit 12.Land capability classes VI located on land unit 5, land unit 6, and land unit 11; 2) land use suitability value obtained was 92.85%. This shows that almost the entire study area (92.85%) is in conformity between the ability of the land and its use. The rest (7.15%) classified as not appropriate. Suitability of the land use study area into the high criteria; 3) Referral land use adapted to the existing conditions of land units. In class III-IV land that does not meet the user or not used optimally, land use options to do that seasonal crops, plantation crops. While on a class VI land use that is not appropriate or not used optimally, land use options to do that forest production and non-agricultural land use.
