Abstract

Peripheral areas are areas on the outskirts of a city that usually have the structure and characteristics of a combination of village and city, both socially, physically, economically, and culturally. The outskirts of Surakarta City include the surrounding regency i.e., Sukoharjo, Boyolali, Karanganyar, Wonogiri, Klaten, and Sragen Regency. These areas have potential tofu and tempeh industry. This research was conducted to determine the spatial distribution patterns and factors influencing the location of tofu and tempeh traders. Data was collected using a questionnaire and analyzed using the average nearest-neighbor pattern. The results show that the spatial distribution pattern is dispersed. Dispersed means that each area is evenly distributed and far from other areas. This happens because the ANN (Average Nearest Neighbor) value is >1. The influencing factor for the location of tofu and tempeh traders in the markets is the location chosen relatively close to where tofu and tempeh traders live so that the distance is not too far. The location was chosen because it has been running a business for generations. The location has good facilities and cleanliness, making it comfortable to carry out buying and selling transactions. This place is busy with buyers from various regions

Abstract

The land cover change analysis in the Upper Bengawan Solo Watershed is crucial because Bengawan Solo is the largest watershed in Java. This study aimed to analyze the spatial and temporal dynamics of land cover change in the Upper Bengawan Solo Watershed during the period 1995-2040. Land cover data obtained from satellite image interpretation were analyzed to identify changes in the periods 1995-2010 and 2010-2025. Furthermore, land cover projections in 2040 were modeled using the CA-Markov method, while the driving factors of land cover change were analyzed using GeoDetector. The analysis showed that settlements, agriculture, and water bodies showed an increasing trend during the periods 1995, 2010, and 2025, while vegetation and bareland showed a decrease. Single-factor analysis showed that slope, soil type, and proximity to rivers and roads had a statistically significant effect on land cover change (p<0.001), although the resulting q statistic value was relatively small. Interaction analysis showed that the combination of factors produced a higher q value than the single factor, especially for the combination of soil and rivers, but the effect remained relatively low. The results of the 2040 projection modeling indicate that settlement and agricultural land cover are expected to continue to increase. Settlements are projected to become the most dominant land cover in the study area, replacing vegetation. If this trend continues without intervention through spatial planning and conservation policies, the ecological balance of the area could potentially be disrupted.
