Abstract

Efforts to develop livestock in East Kalimantan can be carried out by utilizing post-coal mining land. However, the low level of soil fertility and the limited availability of topsoil as a cover soil on post-mining land are constraints that must be considered. Efforts that can be made include planting mycorrhizal cover crops and applying local microorganism-based organic fertilizers (MOL). The experiment was conducted by planting mycorrhizal legume seeds (Siratro) on topsoil and overburden soil placed in 10 kg polybags. Each type of soil was supplemented with local microorganisms (MOL) at concentrations of 0 mL, 10 mL, 20 mL, and 30 mL per litre of water. The experimental results showed that soil type influenced plant height, but both soil type and MOL concentration influenced the fresh weight and dry weight of Siratro plant crowns, as well as VAM root colonization, where higher MOL concentrations reduced Siratro crown production. Root colonization by VAM with increasing MOL concentration in topsoil showed a negative effect, where higher MOL concentrations resulted in lower VAM colonization on plant roots. Conversely, in overburden soil, increasing MOL concentration could increase VAM colonization.

Abstract

This study aimed to analyze the effects of the Group Investigation (GI) and Problem-Based Learning (PBL) models on students’ critical thinking skills and learning motivation in biology learning. A quantitative approach with a quasi-experimental design was employed, involving two experimental classes and one control class at SMA Negeri 1 Muara Wahau. The first experimental class implemented the PBL model, the second applied the GI model, while the control class received conventional instruction. Data on students’ critical thinking skills and learning motivation were collected using achievement tests and questionnaires and were analyzed using two-way ANOVA followed by the Least Significant Difference (LSD) post hoc test. The results revealed that the learning model had a significant effect on both critical thinking skills and learning motivation (p < 0.05). Students taught using the PBL model demonstrated the highest improvement in critical thinking skills and learning motivation, followed by those taught using the GI model, while the conventional learning group showed the lowest outcomes. These results indicate that student-centered learning models encourage active engagement, problem-solving, and collaborative learning, which contribute to enhanced cognitive and motivational outcomes in biology learning. In conclusion, both PBL and GI models positively influence students’ critical thinking skills and learning motivation; however, the PBL model is the most effective. Therefore, the implementation of problem-oriented and collaborative learning models is recommended to improve the quality of biology learning processes and outcomes.

Abstract

Coal mining activities in East Kalimantan have significantly contributed to regional economic development, but they have also resulted in extensive land degradation that requires effective reclamation strategies. The integration of forage crops in reclaimed mine lands offers an opportunity to simultaneously support ecological restoration and livestock production. However, the performance of forage grasses under shaded conditions created by revegetation trees remains insufficiently understood. This study aimed to evaluate the physiological responses, morphological characteristics, and nutritional quality of two forage grass species, Brachiaria humidicola and Stenotaphrum secundatum, grown under shaded conditions on reclaimed coal mine land. The experiment was conducted at the PT Kitadin Embalut reclamation site, East Kalimantan, using a split-plot design with two shading levels (0% and 50%) as the main plots and two grass species as subplots. Each treatment was replicated six times. Variables measured included dry matter yield, leaf-to-stem ratio, chlorophyll content (a, b, and total), crude protein, and crude fiber content. The results showed that a 50% shading level significantly influenced physiological and morphological responses of the grasses. Stenotaphrum secundatum exhibited a marked increase in chlorophyll content under shaded conditions, indicating a stronger acclimation to low light environments compared with Brachiaria humidicola. Shading also reduced the leaf-to-stem ratio in both species. However, dry matter production was not significantly affected by shading, suggesting that both grasses were able to maintain biomass accumulation under moderate shade conditions. Shading slightly reduced crude protein and crude fiber contents.
