Abstract

This study evaluates the effect of installation methods of low-cost capacitive soil moisture sensors on field measurement performance. Six sensors were tested using two installation methods, namely side mount and bottom mount, at three depth variations (0.2 m, 0.5 m, and 1 m). A monitoring system was developed using an ESP32 microcontroller integrated with the Firebase cloud platform for real-time data acquisition, powered by a solar panel. Field testing was conducted from March 10 to April 16, 2026, with GPM satellite rainfall data used as a supporting parameter. Calibration results showed a strong linear relationship between sensor output voltage and volumetric water content with R2>0.9 for all sensors. The bottom mount method produced valid readings from the beginning of the testing period with good response to rainfall events at all depths. In contrast, the side mount method experienced a delay in sensor–soil contact formation, resulting in invalid data during the early phase. The findings indicate that the quality of physical contact between the sensor and soil is a key factor in reading reliability, and the bottom mount method is more effective for long-term field soil moisture monitoring.

Abstract

Land-use change is one of the primary drivers influencing watershed hydrological conditions. Uncontrolled conversion of land in the Benanain watershed, particularly in the Temef sub-watershed, has the potential to increase surface runoff and accelerate soil erosion, which in turn increases sedimentation within the Temef Dam reservoir. This study aims to analyze the impact of land-use changes between 2018 and 2024 on surface runoff and soil erosion using the Soil and Water Assessment Tool Plus (SWAT+). Data used include rainfall, climate, DEM, soil type maps, and land cover maps which were processed through watershed delineation, HRU formation, and hydrological simulations. The results indicate significant land-cover changes, particularly a reduction of shrubland by 27.65% and an increase in forest area by 23.74%. These changes significantly affect runoff patterns, where in 2024 sub-watershed 6 produced the highest annual runoff of 611.96 mm and sub-watershed 8 the lowest at 209.93 mm. The findings provide a comprehensive understanding of hydrological dynamics in the Temef watershed and serve as a scientific reference for soil-water conservation planning and sustainable watershed management.

Abstract

This study aims to analyze the economic feasibility of utilizing peat-based briquettes as an alternative household energy source in rural Central Kalimantan. The research adopts a comparative literature review approach, examining previous studies on peat briquettes, rice husk briquettes, and bagasse briquettes. The analysis focuses on technical parameters (calorific value, moisture content, ash content, burning duration) and economic parameters (production cost, selling price, profit margin, and investment feasibility indicators). The findings indicate that peat briquettes have higher calorific values (5,800–6,200 kcal/g) and longer burning duration (±240 minutes) compared to other biomass fuels. Economically, peat briquettes demonstrate lower production costs (±Rp 3,500/kg), higher profit margins, and positive feasibility indicators, including a positive NPV, BCR of 1.8, and a payback period of approximately two years. Therefore, peat briquettes are economically feasible to be developed as a community-based alternative energy in rural Central Kalimantan, although environmental sustainability must be considered through biomass diversification and regulated peat utilization.

Abstract

Flooding on the Tangerang-Merak Toll Road at KM 50+000–51+000, Cikande, in January 2026 disrupted the national logistics corridor. This study evaluates the macro-level causes of inundation through integrated hydrological analysis using a Geographic Information System (GIS) approach with scoring, overlay, and hydrological modeling techniques across 14,516 spatial units in the Cidurian Watershed. The evaluation covers spatial drainage capacity, Digital Elevation Model (DEM), flow accumulation, SWAT+ modeling, and its alignment with the Cikande Industrial Area Detailed Spatial Plan (RDTR). Analysis indicates that 96.2% of the study area has low drainage capacity, an average Curve Number of 94.2, and a surface runoff ratio of 0.83. The flooding mechanism is identified as compound flooding involving three simultaneous processes: local channel tailwater submergence driven by high Cidurian River levels, backwater accumulation in upstream toll road depressions, and overtopping across the road body. DEM analysis confirms Bakung Village as the flow pathway and Songgom Jaya Village as the final accumulation zone. The findings confirm that the flood stems from the interaction of main river overflow, loss of hydraulic gradient, and watershed capacity limits rather than local drainage constraints alone. Three technical mitigation scenarios are recommended: elevating the road, river normalization with embankments, and expanding cross-drain capacity integrated with collector drains and downstream normalization.
