Abstract

Monitoring and Evaluation of Landuse Changes based on Remote Sensing in Klungkung District, Klungkung Regency. Bali Province is one of the tourism destinations in Indonesia, the tourist destinations, offered include beauty of nature, art, culture traditions, and historical buildings one of them is in the Klungkung District such as Kertagosa, Gunarsa Museum the Klungkung Monument. Klungkung District has a large population that a 65,273 people, which can changes in landuse, therefore the research about monitoring and evaluation of landuse change in Klungkung district is needed. The purposes of this research are to determine landuse changes in Klungkung District, the level of accuracy of the classification result of Landsat imagery in 2022, and the relation between classified land use map and spatial planning of Klungkung Regency. The method which is used in this research is the maksimum likehood classification (MLC) in the land use supervised classification. Digital classification for landuse landcover were analyst using semi-automatic classification plugin (SCP) in QGIS 3.22 LTR Apps. The result shows that, it was found that built-up land has a regularity of change of 28,155 ha/yr, rice fields with a regularity of change of 50.5 ha/yr, bare land with an area of 16.88 ha/yr, and dryland farming with a regularity of change reaching 61.7 ha/yr. The overall accuracy of this research was 82.42 % and a kappa index 0.75. The overlay by spatial planning was found that there was a discrepancy the land use in 2022.

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.
