Abstract

Mapping of Climate Suitability and Variability for Corn Based on Geographic Information System (GIS). Each plant requires different growing conditions according to a certain climate. Climatic conditions can vary, such as El Nino and La Nina, which causes changes in the climate suitability of corn. Evaluation of climate suitability is important because climate factors are dynamic and difficult to control. This study aims to map the climate suitability of corn and map the climate suitability of corn when climate variability occurs in Bali Province. The analytical method used is matching and mapping using GIS. The results of this research showed that the climate suitability of normal period for corn in Bali Province is quite suitable (S2) and mostly (89.33%) is marginal (S3). Based on the limiting factors, it is divided into S2tc, S2wa, S2watc, S3wa and S3watc with the majority (498,568.26 ha) being S3wa. In general, climate variability causes changes in the area suitable for planting corn in Bali Province. El Nino had an impact on increasing the S2 area in the 2015 strong El Nino so that the S2watc area became 214,324.27 ha and the overall S2 area became 44.53%. The strong La Nina in 2010 reduced the overall S2 area to 0.49%, especially S2watc remaining only 2,756.75 ha.

Abstract

Application of Remote Sensing and GIS for Land Use Mapping and Impact on Food Supply in South Denpasar. The increasing demand for land, driven by population growth, societal development, and economic progress, leads to land use conversion. The conversion of agricultural land to non-agricultural purposes has implications for food availability. This research aims to assess land use changes over an 11-year period (2012-2023), determine the presence of subak (traditional Balinese irrigation system) in 2041 based on the Regional Spatial Plan (RTRW) map, and project the analysis of food availability in 2030 and 2040 due to land use changes. The methods employed include satellite image interpretation, digital mapping, map overlay, and food availability analysis. The research findings indicate land use changes from 2012 to 2018 resulted in a conversion of 140,66 hectares (23,44 ha/year), and from 2018 to 2023, a conversion of 18,8 hectares (3,76 ha/year), with a total conversion of 159,46 hectares (14,50 ha/year) from 2012 to 2023. Based on the RTRW spatial plan map for 2021-2041, South Denpasar is projected to potentially 4 subak located outside agricultural zones. Land use changes in South Denpasar have implications for the rice food balance, with a projected deficit of (-19.973) tons in 2030 and (-20.563) tons in 2040. Reevaluation of land use allocation policies is necessary due to their impact on food availability, environment, social, and culture.

Abstract

Monitoring The Conversion of Rice Fields and Mapping The Status of Farmers in Subak Kerdung and Subak Cuculan, Denpasar City. Subak Kerdung and Subak Cuculan are subaks that are included in the Green Open Space area of ??Denpasar City. The designation of this two subak as an open space areas for Denpasar City does not reduce the land conversion level. Therefore, it is necessary to have more protection by determining the area for Sustainable Food Agricultural Land (SFAL). Based on Government Regulation No. 25 of 2012, the preparation of SFAL needs to be equipped with a database, some of which are data on human resources and farmer status. This study aims to create a map of land-use change (2012-2021), a map of the distribution pattern of farmer status, and a human resources database. This study uses image analysis methods as well as surveys and mapping. The research stages include literature study, interpretation of satellite imagery, field surveys, image reinterpretation, and mapping and preparation of information systems. The results showed that for nine years, there was a conversion of 66.61 ha in Subak Kerdung and 22.62 ha in Subak Cuculan. The number of farmers in Subak Kerdung is 133 people, 121 people are sharecroppers with a total land area of ??93.2 (91.75%), and 18 people are owner farmers with a total land area of ??8.47 ha (8.25%). The number of farmers in Subak Cuculan was 24 people; 22 were sharecroppers with a total land area of ??7.43 ha (84.24%). Owner farmers opened two people with a total arable area of ??1.39 ha (15.76%). Farmers in Subak Kerdung and Subak Cuculan dominate the productive age (31-60 years). The average size of land cultivated by farmers in Subak Kerdung is 0.76 ha/person, and in Subak Cuculan is 0.36 ha/person. The results of this study are expected to be used by the Denpasar city government as a basis for evaluating and enforcing the law and as a reference for determining SFAL in Subak Kerdung and Subak Cuculan.

Abstract

Agricultural Commodity Land Suitability and Geospatial-Based Land Use Planning in Malaka District, East Nusa Tenggara. Data and information on land suitability classes for various plant commodities must be available in Malaka District on a geospatial basis so that they are easily accessible. The technology used is a geographic information system (GIS). The aims of this study were to: (1) obtain land characteristics for land suitability classes, (2) map actual and potential land suitability classes, (3) land use plans based on land suitability, (4) provide a land suitability information system. This research was conducted in two sub-districts in Malaka Regency, East Nusa Tenggara. The analysis carried out in this study included: physiographical analysis, field surveys, soil analysis in the laboratory, land suitability analysis, making land suitability maps and land use planning maps, building a geospatial-based land suitability information system. The actual land suitability class for food crops, horticulture and plantations is classified as marginal suitable (S3wa1wa2wa3rc3na1na2na3eh1eh2Ip1) to unsuitable (Nwa2xc) limiting rainfall, dry months, humidity, effective depth, N-total, P2O5, K2O, salinity, slope, erosion hazard and rocks surface. Improvement efforts include tillage, fertilizing urea, phonska, KCl, making drainage channels, setting planting times, making ponds and making bench terraces. Potential land suitability classes are very suitable (S1), moderately suitable (S2wa1wa2rc3xceh1eh2Ip1) to marginally suitable (S3wa2) limiting rainfall, dry months, effective depth, salinity, slope, erosion hazard and surface rocks. West Malaka and Central Malaka Districts first priority in flat areas to develop corn, cassava, cashew nuts, green beans, shallots, tomatoes and watermelons as an alternative. Whereas in the Central Malaka District, the hilly relief is more suitable for coconut, cocoa and cashew plantations and the karst hill relief is an alternative for the development of corn, cassava, green beans, shallots, tomatoes and watermelons.

Abstract

The existence of Sebangau National Park in Central Kalimantan is a government effort to save and protect ecosystems that have started to deteriorate in the Sebagau area due to logging, poaching, and forest burning for land clearing conducted illegally by the community. In addition to these problems, the existence of Sebangau National Park is also to minimize the impact caused by global warming in the form of high air temperatures, which can trigger forest and peatland fires which occur almost every year in Palangka Raya City. Forest fires can damage ecosystems, releasing carbon and greenhouse gases into the atmosphere so that they can pollute water, soil and air. In addition, the smoke produced can also interfere with public health. The involvement of Pentahelix actors in the management of the Sebangau National Park tourism destination in Palangka Raya City is to make tourism at this destination sustainable. This research is designed as qualitative research supported by quantitative data, often referred to as a mixed method. Data collection was conducted through observation, semi-structured interviews, document studies, and questionnaires. The analysis method used in this study is Interpretative Structural Modeling (ISM) to map the role of Pentahelix with three elements consisting of: actor elements, need elements, and constraint elements. The ISM analysis results identified the main actors in the management of the Sebangau National Park tourism destination in Palangka Raya City as the Sebangau National Park Office in Palangka Raya City (government) and the Getek Maju Mandiri Group (community). The primary need in management is the Pentahelix collaboration and sustainable ecotourism. The main constraints in management are the incomplete availability of facilities and infrastructure and the lack of coordination between the government, private sector, and community.
