Abstract

Background: Protected forests in the Moramo District play a critical role in maintaining ecosystem balance, but they are increasingly threatened by human activities such as illegal logging and land use change. Vegetation density shifts can disrupt ecosystem functions, particularly the hydrological cycle. This study aims to analyze spatial and temporal changes in vegetation density in the Moramo District Protected Forest using remote sensing. Methods: To detect vegetation density changes, the NDVI (Normalized Difference Vegetation Index) algorithm was employed using satellite imagery from Landsat OLI 8 (2013 and 2018) and Landsat OLI 9 (2023), processed with GIS software. NDVI values range from -1 to 1, allowing for vegetation condition assessment based on spectral reflectance. Findings: Results show a degradation trend in dense vegetation, with a decrease of 67.25 ha (2.86%) during 2013–2018 and 289.11 ha (12.31%) during 2018–2023. Conversely, moderately dense vegetation increased by 68.45 ha (2.91%) and 300.21 ha (12.78%) over the same periods, indicating signs of vegetation regeneration. Conclusion: Despite some vegetation recovery, forest ecosystems continue to face high pressure. More adaptive conservation strategies supported by spatial monitoring are needed to reduce degradation and support long-term sustainability. Novelty/Originality of this article: This study uniquely integrates a multi-temporal NDVI-based approach with socio-ecological analysis and GIS tools to monitor vegetation dynamics. It offers valuable insights for adaptive forest management in the Moramo District Protected Forest, an area previously lacking detailed environmental change analysis.

Abstract

Population of lactic acid bacteria (LAB) in the rumen of fattening livestock is relatively high and has the potential to be utilized. This study aimed to screen and identify LAB from the rumen as probiotic candidates. The research used rumen liquid from cattle, goats, and sheep collected from slaughterhouses in Bondowoso. The screening and identification processes were conducted at the Livestock Agroindustry Laboratory, Faculty of Agriculture, University of Jember. The screening included colony morphology, Gram staining, cell shape, catalase test, and Carbon dioxide (CO2) gas production ability. The final identification of potential probiotic bacterial candidates was based on their bile salt tolerance. The results showed that there were LAB candidates with 22 isolates (from sheep/OS), 19 isolates (from cattle/OC), and 18 isolates (from goats/OG). The bacterial colony shape included oval (2OS, 1OC), circular (11OS, 18OC, 12OG), irregular (7OS, 6OG), and spindle (2OS). Colony sizes ranged from small (0.5–1.2 mm: 7 OS, 9OC, 4OG), medium (1.2–3.0 mm: 7OS, 7OC, 7OG), to large (3.0–5.0 mm: 8OS, 3OC, 7OG), with the majority of colonies being white and cream-colored, and a minority being yellow. All bacteria were Gram-positive, with coccus (19OS, 14OC, 2OG) and bacillus (3OS, 5OC, 16OG) shaped cells. All samples were capable of producing CO2 gas, and 50% of the isolates possessed catalase enzymes. Based on bile salt tolerance tests, 15% of the isolates had a survival rate of over 50%. In conclusion, LAB from the rumen, particularly goats, were identified as potential probiotic candidates for further development.

Abstract

The physical quality of soil is determined by quantitative measurement tools, which are expressed in the form of soil quality indices. Methods for determining soil quality have been developed, but none have been standardized. This research aimed to determine the results of the soil physical quality index based on two methods, namely 1) simple additive SQI, and 2) statistically modeled SQI, followed by a sensitivity test to determine which method is more sensitive. This research was conducted in the Rembangan Sub-watershed, which comprises five sub-districts: Jelbuk, Arjasa, Patrang, Sukorambi, and Panti, with elevations ranging from 125.91 to 854.67 meters above sea level. Based on the paired t-test results, the soil physical quality index between the two methods was significantly different, with a p-value of 0.002. Meanwhile, the sensitivity test results showed that the statistically modeled method was more sensitive than the simple additive method. Thus, the statistically modeled method is the method that can be used to assess the soil physical quality index for land management guidance. The poor or low-quality class dominates the soil quality class, covering an area of 2,088.43 ha (79.43%). Land management actions based on soil quality are divided into three criteria: 1) “fixed efforts” for low-quality soil, 2) “enhanced efforts” for medium-quality soil, and 3) “maintenance efforts” for good-quality soil.

Abstract

Microlearning is a learning method that utilizes media in the form of videos to stimulate students' interest in learning. This research aims to produce microlearning-based learning media on the topic of environmental change and conservation for high school (SMA/MA) students. The research method used is a quantitative approach with a development research type, employing the 4D model (Define, Design, Development, Dissemination), which is limited to the Development stage.
