Abstrak. Seiring terjadinya penyimpangan penggunaan lahan sangat sering terjadi terhadap rencana tata ruang wilayah (RTRW). Daerah pinggiran kota merupakan wilayah yang banyak mengalami perubahan penggunaan lahan terutama perubahan penggunaan lahan pertanian menjadi non pertanian. Penelitian ini bertujuan untuk menganalisis perubahan penggunaan lahan pertanian di Kabupaten Aceh Selatan tahun 2013 dengan tahun 2017 dan menganalisis keselarasan penggunaan lahan pertanian eksisting tahun 2017 dengan pola ruang Kabupaten Aceh Selatan tahun 2013-2033. Metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan teknik survai. Sedangkan analisis data spasial menggunakan SIG dengan konsep extract, overlay dan intersect. Hasil kajian menunjukkan hasil koreksi pada pengunaan lahan pertanian tahun 2013 dengan tahun 2017 didapatlah luas penggunaan lahan pertanian yang telah beralih fungsi seluas 8.041,56 ha, yang mana pada lahan sawah seluas 3.680,30 ha dan pada pertanian lahan kering seluas 4.361,26 ha. Penggunaan lahan pertanian yang telah beralih fungsi tersebut telah menjadi berbagai macam penggunaan lahan lainnya yang tersebar di seluruh Kabupaten Aceh Selatan, penggunaan lahan pertanian yang selaras dengan rencana pola ruang memiliki luas 36.293,85 ha (91,30%), penggunaan lahan yang tidak selaras yaitu Penggunaan lahan eksisting tidak selaras dengan rencana pola ruang seluas 1.513,53 ha (3,81%), dan belum terlaksana atau belum terealisasi terhadap lahan pertanian yang direncanakan terhadap pola ruang atau masih dapat berubah sesuai dengan rencana pola ruang seluas 6.711,08  ha (14,44 %). Analysis of Functional Land Distribution of Agriculture in District Aceh SelatanAbstract. Absorption of deviation of land use is very frequent to spatial planning (RTRW). Suburban areas are areas that have undergone many changes in land use due to changes in agricultural land use to non-agricultural use. This research was conducted for 2013 with 2017 and analysis of existing agricultural land use in 2017 with South Aceh Regency spatial pattern year 2013-2033. The method used in this research is descriptive method with survey technique. While spatial data analysis using GIS concept with overlay and intersect concept. The results showed that agricultural land in 2013 with the year 2017 obtained the wide use of agricultural land that has a function conversion of 8,041.56 ha, which in the rice field area of 3,680.30 ha and on dry land of 4,361.26 ha. The use of converted agricultural land into various land uses scattered throughout the District of South Aceh, different use of agricultural land with plans of wide spatial pattern 36,29,85 ha (91,30%), land use that is not aligned Land use the existing is not aligned with the plan of the pattern of the space of 1,513.53 ha (3.81%), and has not been realized or not yet realized on agricultural land that allows the pattern of space can be changed in accordance with the Plan of Space Pattern covering 6,711,08 ha (14,44%).

Trade Off

Background The discovery-dominance trade-off is the inverse relationship between the ability of a species to discover resources and the species’ dominance of those resources; a paradigm used to explain species coexistence in ant communities dependent on similar resources. However, factors such as stress (e.g., temperature) or disturbance (e.g., removal of biomass) associated with the change in land use, can modify this trade-off. Here, we aimed to determine the potential effects of land use change on dominance hierarchy, food preferences and on the discovery-dominance trade-off. Methods An experiment with baits was used to investigate the dominance hierarchies of ant communities in a temperate mountain habitat in central Mexico. We evaluated the dominance index (DI), food preferences and discovery-dominance trade-offs of ants inhabiting two types of vegetation: a native oak forest and agricultural land resulting from agricultural land use and grazing. Results The ant communities in both environments were comprised of three species of ants (Monomorium minimum, Myrmica mexicana, and Camponotus picipes pilosulus), four morphospecies (Pheidole sp.1 and Pheidole sp.2, Temnothorax sp. and Lasius sp.) and one genus (Formica spp.). All Formicidae showed values of intermediate to low DI, and this factor did not seem to be influenced by the change in land use. Ants in the modified vegetation (i.e., agricultural land) were found to be numerically greater. Overall, a higher number of visits were registered to the tuna bait, although the duration of foraging events to the honey baits was longer. However, foraging times were dependent on the species considered: the generalized Myrmicinae, M. minimum, the ant species with highest DI, foraged for longer periods of time in the agricultural land and on the tuna bait. Meanwhile, the cold-climate specialist Formica spp., with a lower DI, foraged for longer periods of time in the oak (although not significant) and on the honey bait. We found little evidence of the discovery-dominance trade-off; instead, we found considerable diversity in the strategies used by the different species to access resources. This range of strategies is well represented by the generalized Myrmicinae M. minimum, the cold-climate specialists Formica spp. and Temnothorax sp., and the rare species, as the cold climate specialist Lasius sp. (insinuators). Conclusions Our evaluation shows that transformation of the original habitat does not appear to affect the hierarchical dominance of the ant communities, but it does affect their food preferences. Species with higher DI values such as the generalized Myrmicinae are more skilled at resource acquisition in modified habitats. Our results suggest that change in land use promotes an increase in the diversity of foraging strategies used by different ant species. This diversity may contribute to resource partitioning which favors coexistence.

The Impact

This study examines the impact of agricultural land use change into a petroleum mining area to farmers’ socioeconomic conditions around petroleum mining project area in Gayam District of Kabupaten Bojonegoro. The analyses used a mix method, using both quantitative and qualitative approaches. The quantitative approach is used to determine the impact of agricultural land use change on the social and economic aspects with the respondent farmers were supported with a scoring method to determine the condition of socioeconomic vulnerability of farmers, while the qualitative approach carried out through in-depth interviews to some informants who have been affected by the project. The results shows that the presence of the petroleum mining industry has not had a positive impact yet on the farmers’ socioeconomic conditions. By the 700 hectares of agricultural land conversion, the agricultural production capacity of the area tends to decrease, including by the decreasing of the productivity of some agricultural land in a radius of 500 m from the fenceof the mining area as they are affected by the fence’s spotlight. The farmers' income also tends to decrease because of the decreasing of their working hours as the big loss of agricultural land in the area. As a result, many farmers should work outside of the area to search replacement of the arable land. These situations lead to a moderate condition of social and economic vulnerability for the farmers, especially for those who still have sufficient assets to meet the needs of their economic.
