Abstract

The purpose of this research is to design a spatial model of urban settlement areas using the Cellular Automata approach in South Minahasa Regency. The research location is located in a sub-district in South Minahasa Regency which has a delineation of urban settlement areas namely Tumpaan, Tareran, Amurang Timur, Amurang, Amurang Barat, Tenga and Sinonsayang Districts, covering an area of ​​656.6 Km2. Primary data collection methods are: Field observation and distribution of questionnaires to academics, government and local communities. Secondary data collection methods, namely: literature review and data request survey. The method of analysis is quantitative analysis using AHP and spatial analysis based on Cellular Automata. The results of the research show that the direction of modeling starts towards the east and south of the research location. Urban residential land in the research location experienced a growth of 4.19% from the previous year in 2014 covering an area of ​​11.96 Km2 increasing by 15.26 Km2 to 27.22 Km2 in 2034. The modeling results also show that in the 2014-2019 range is the range in which growth the highest settlement that occurred was 5.7%. The development of settlements resulted in the conversion of several land uses, namely alang-alang land and mixed gardens. Urban settlements in Tareran District are settlements that experience greater growth among settlements in other districts with a percentage reaching 9.1%.

Abstract

This study aims to analyze the location of land availability and the direction of land availability from the aspect of Spatial Designation Plans and land issues. The research was carried out from November 2021 to January 2022 which is located in the Likupang tourism area. The method used in this research is Overlay Analysis with GIS software and descriptive analysis obtained through Indepth Interview. The data used are primary data and secondary data. The results of the research analysis obtained that the availability of land at the location was classified into available and unavailable. The area of available land is 829.47 Ha (17.97%) while the area of land that is not available is 3,716.55 Ha (80.54%). The available land locations consist of available non-agricultural cultivation covering an area of 664.86 Ha (14.41%) and agricultural cultivation covering an area of 164.61 Ha (3.57%). The location of land that is not available is limited to protected activities covering an area of 1,030.06 Ha (22.32%), optimal use of non-agricultural land of 217.33 Ha (4.71 %), optimal use of agricultural land covering an area of 2,145.78 Ha ( 46.5%) and land use adjustment of 323.38 Ha (7.01%). The direction of land availability, namely the location of the available land is directed based on the allotment of space so that it is obtained for investment activities covering an area of 664.86 hectares and commodity activities covering an area of 164.61 hectares. At the location of the available land, there is a potential land dispute of 2 hectares. So that the availability of clean and clear land (no dispute) is (827.47%).

Abstract

Cropped paddy fields threaten rice self-sufficiency and rural livelihoods in many parts of Indonesia. This study examines the spatial dynamics and economic drivers of paddy field conversion in South Minahasa Regency, North Sulawesi, focusing on Tumpaan and Tatapaan Districts. Spatial analysis of land-use data for 2019 and 2024 was combined with farm-level surveys of 30 farmers and comparative farm-budget analysis for irrigated rice and four alternative crops (melon, watermelon, chilli and patchouli). The results show substantial paddy field loss, with net reductions of approximately 160.749 ha in Tumpaan and 82.68 ha in Tatapaan over the study period. Farm-budget comparisons indicate that irrigated rice on 0.62 ha yields only a small positive net cash income, whereas melon and watermelon on 1 ha each and chilli on 0.60 ha generate very high net cash returns in the observed season; patchouli, by contrast, is clearly unprofitable. Farmer interviews highlight high production costs and low margins for rice, labour shortages, difficulties in accessing fertiliser, deteriorating irrigation infrastructure and attractive market opportunities for horticultural crops as key drivers of conversion. The findings suggest that paddy field protection policies will remain ineffective if they are not accompanied by measures that improve the profitability and reliability of rice farming while recognising farmers’ rational responses to income opportunities from alternative crops. Keywords: paddy field conversion; farm income; horticultural crops; spatial analysis
