Abstract

The rapid advancement of remote sensing technology and Geographic Information Systems (GIS) has substantially enhanced the accuracy, efficiency, and comprehensiveness of spatial data acquisition and analysis. This study investigates land-use patterns within a selected area of Belayung Baru Village, Kertak Hanyar District, Banjar Regency, South Kalimantan, employing high-resolution drone imagery to generate detailed spatial information. A multirotor drone-based mapping survey was utilized, with data processed through Agisoft Metashape and ArcGIS to produce orthomosaic images and thematic land-use maps. The results reveal that the study area encompasses approximately 93.74 hectares, predominantly consisting of rice fields (65.86 ha), residential zones (17.15 ha), and wetlands (6.69 ha). Visual interpretation of drone imagery demonstrates pronounced seasonal contrasts between rice fields and wetlands in terms of spectral tone, texture, and spatial pattern. Furthermore, the dynamic hydrological conditions of the wetland ecosystem substantially influence local agricultural cycles, restricting cultivation to the dry season when the water table recedes. Overall, this study underscores the effectiveness of drone-based geospatial technology in delivering precise spatial mapping outputs that support sustainable land-use management and planning.

Abstract

Fluctuations in operating load at the Cilacap Steam Power Plant (PLTU) often cause changes in steam turbine performance that affect generation efficiency and fuel consumption. This study aims to assess the effect of load variations on turbine heat rate, measure changes in thermal efficiency, and analyse their impact on fuel consumption and generation costs. A quantitative correlational method was applied using secondary data from the December 2023 periode, including electrical load parameters, steam flow rate, inlet-outlet enthalpy, and generator output. Heat rate and thermal efficiency calculations were performed based on thermodynamic formulas, while fuel consumption and cost analysis were conducted through comparisons of values per kWh. The results show that an increase in operating load consistently reduces the heat rate and improves thermal efficiency, meaning that steam energy is utilised more optimally. Additionally, fuel consumption and generation costs tend to decrease as the load approaches optimal conditions. These findings underscore the importance of maintaining the operating load within an appropriate range to maximise energy efficiency, reduce fuel consumption, and minimise electricity production costs at the Cilacap Coal-Fired Power Plant

Abstract

Background: Global climate change significantly affects carbon dynamics in perennial crop ecosystems, including agroforestry systems. This study aims to analyze carbon dynamics in three types of agroforestry systems: agrosilvopastoral, agrosilvicultural based on horticultural crops, agrosilvicultural based on woody plants, and to identify the diversity and types of vegetation. Methods: The study was conducted from January to March 2025 using field surveys and purposive sampling in Wonosalam, East Java, Indonesia. Laboratory analyses included physical properties (soil texture and bulk density), chemical properties. Results: The regression model showed R2 =0,419 Idicating that 41,9% of soil orgnaik carbon variation is explained by plant biomass carbon stock, highlighting its significant contribution to soil carbon accumulation. Conclusions: The agrosilvicultural system based on woody plants provides the highest contribution to carbon dynamics compared to other types of agroforestry, due to its vegetation composition dominated by woody and perennial plants. The even distribution of the Importance Value Index (IVI) reflects a stable and balanced ecosystem, as observed in plot 3, where excelsa coffee (Coffea excelsa) has an IVI of 37.78%, Durian (Durio zibethinus) has 35.56%, and banana (Musa spp) also has 37.78%. Keywords: Agroforestry; Biomass; Carbon Dynamics
