Abstract

Indonesia is a country with abundant natural resources, one of which is green open spaces and vegetation. Land use change dynamics are the result of economic needs arising from development and community activities. This study was conducted to determine land use change dynamics and bird diversity as bioindicators of these changes. Land use change dynamics were mapped using remote sensing and satellite image analysis. The methods used in this research include field data collection on land cover and bird diversity, as well as analysis of diversity indices (H'), richness (R), and evenness (E) to evaluate biodiversity conditions. The study results show that vegetated areas experienced fluctuating increases (2014: 1,072.1 ha, 2019: 1,389.2 ha, and 2024: 1,538.8 ha), agricultural areas decreased (2014: 2,159.6 ha, 2019: 1,721.4 ha, and 2024: 1,538.8 ha), and built-up areas increased (2014: 1,295.1 ha, 2019: 1,721.4 ha, and 2024: 1,384.9 ha). The dynamics of change will affect bird diversity with values in vegetated areas H': 2.0532, agricultural areas H': 1.7350, and built-up areas H': 1.4415. Monitoring land changes is important as it is a key factor in regional spatial planning and one of the ways to protect existing green open spaces.

Abstract

Indonesia is one of the world's largest producers and exporters of coal. Approximately 60 percent of Indonesia's total coal reserves consist of low-quality coal, which is cheaper and has a calorific value of less than 6,100 kcal/gram. In addition to the combustion of low-quality coal waste, there are also Fly Ash and Bottom Ash (FABA). The circular economy has become an important part of the economic model approach, aiming to drive economic growth while minimizing social and environmental damage. Innovations related to coal waste utilization and post-mining reclamation solutions are key aspects of this approach. This study aims to utilize coal waste as a medium for land reclamation using the circular economy concept. Coal Ball Seed (CBS) is an innovation that packages coal into balls containing seeds, growing media, and nutrients, providing the necessary nourishment for seed growth. The best binder found in this study was soil. Coefficient tests showed that the significance level for the composition was below the 0.05 threshold. The test results indicated aSig. value of 0.00, confirming that Coal Ball Seed (CBS) significantly affects the growth of sengon seeds (Falcataria moluccana. The R-square summary test revealed a value of 38.1%, meaning that the growth of Falcataria moluccana seeds is influenced by the composition of CBS itself, while the remaining 61.9% is influenced by other factors. Thus, the optimal CBS composition uses a ratio of Bottom Ash: Clay: Antracol: Liquid Nutrient. The average nutrient content of CBS was measured at N 9 mg/kg, P 2.6 mg/kg, and K 4.3 mg/kg. The utilization of coal waste into CBS plays a role in the circular economy, and its spherical shape makes it highly feasible for distribution via drones in large-scale reclamation efforts
