Abstract

Former clay mining areas often face soil degradation that makes it difficult for vegetation to thrive, even after reclamation. This study explores the physical and chemical characteristics of soil in the reclaimed land of PT Solusi Bangun Indonesia Tbk in Cilacap, aiming to understand how effective the rehabilitation efforts have been. Soil samples were taken from six locations, chosen based on differences in vegetation cover and land elevation. The analysis focused on physical properties such as pH, moisture content, temperature, specific gravity, and porosity, along with chemical aspects like macronutrient levels and heavy metal content. Results showed that soil pH ranged from neutral to slightly acidic, with moisture content varying across the site. While macronutrients were generally adequate for plant growth, their distribution was uneven. Some heavy metals, particularly cadmium and silver, were found in concentrations above recommended environmental limits, whereas lead and arsenic levels remained within safe thresholds. Overall, the reclamation process has helped improve soil conditions, but additional steps—like adding lime, incorporating organic matter, and applying specific remediation techniques—are needed to boost soil fertility and reduce contamination risks. Continued monitoring and adaptive strategies will be key to sustaining the health of the reclaimed landscape

Abstract

Environmental quality in Indonesia remains under sustained pressure due to ongoing deforestation, resource-intensive economic growth, and persistent regional development disparities. This study analyzes the influence of the Human Development Index (HDI), Gross Regional Domestic Product (GRDP), deforestation, and regional government revenue and expenditure budgets on the Environmental Quality Index (EQI) across 33 Indonesian provinces. The analysis employs panel data regression, with a Fixed Effects Model selected based on the Hausman specification test. The results reveal that HDI exerts a positive and statistically significant effect on environmental quality, with a one-point increase in HDI corresponding to a 1.988-point rise in the EQI. Deforestation and regional government budget variables do not demonstrate statistically significant effects on the EQI. These findings suggest that higher levels of human development are associated with improved environmental conditions, whereas economic growth trajectories that are predominantly driven by natural resource exploitation continue to degrade environmental quality. Accordingly, regional development policies should be directed toward strengthening human development performance, integrating environmental considerations into economic growth processes, and enhancing the effectiveness of regional budget allocations for environmental sustainability, in order to achieve inclusive and sustainable development.

Abstract

Mangroves are coastal vegetation that lives in tidal zones, providing ecosystem services such as biota habitats, abrasion barriers, breakbreaks, and significant carbon sequestration for climate change mitigation. However, the mangrove ecosystem in Indonesia, including in Rembang District, which includes Pasarbanggi, Tireman, and Kabongan Lor Villages, has been degraded due to land conversion into ponds, logging, and reclamation. This study aims to analyze the spatio-temporal dynamics of mangrove cover in 1985-2025 in Rembang District using MVI based on Landsat 5 (1985, 1995), Landsat 7 (2005), and Sentinel-2A (2016, 2025) satellite imagery. The analysis was carried out with a composite of NIR, Green, and SWIR Bands, digitization, cropping, cover classification, and analysis of mangrove cover changes. The results of the study show that the area of mangrove cover has experienced very significant fluctuations. The period 1985–2005 was dominated by heavy degradation (-67.93%), while the period 2005–2025 recorded a very strong recovery of mangrove ecosystems (+339.56%), with the high cover class increasing from 17.39 ha to 27.40 ha. The success of rehabilitation and reduced land conversion have succeeded in restoring the area of mangrove forests while improving the quality of mangroves in Rembang District.

Abstract

Using appropriate bedding can enhance the welfare of beef cattle. This study was designed to evaluate the daily behavior of beef cattle kept on different types of bedding. Field research was conducted over a period of two months, using eight beef cattle, which were divided into two groups based on the type of bedding used, namely straw and rubber mats. The daily behaviors observed were the duration and frequency of eating, aggressive behavior, lying down, sleeping, standing, and elimination. The observation used was an intermittent method. The first group consisted of a pen block with straw bedding, and the second group consisted of a pen block with carpet bedding. Data analysis used the t-test and analysis of variance at a significance level of 5%. The results showed that all parameters did not reveal any differences; however, sleeping behavior was higher (P < 0.05) in the straw-bedded pens, with the highest percentage of sleep occurring in the afternoon. This study concluded that both straw and rubber carpet bedding are still capable of supporting the normal expression of the main daily behaviors of cows. Both types of bedding are still suitable for use in beef cattle husbandry systems.
