Biofertilizer is an environmentally friendly fertilizer, has a long release time so it can be absorbed by plants long enough, and has enzymatic activities such as binding nitrogen and dissolving phosphate. Phosphate solubilizing bacteria (BPF) can dissolve phosphate that was previously unavailable to become available. This research aims to further examine the potential of BPF isolates from Kalimantan as a liquid biofertilizer agent using coconut water as a medium. The research was conducted for 3 months, from June to August 2023 at the Microbiology Laboratory, Biology Department, Faculty of Mathematics and Natural Science Tanjungpura University, Pontianak. This research used a Completely Randomized Design (CRD) with 8 treatments and 3 replications using the Total Plate Count method. The results of the study showed that the highest treatment is a treatment of A4 on day 6 with an average density of 9,4x108 CFU/mL. The BPF which has the highest potential as a biofertilizer is found in treatment A4, the combination bacterial isolates of Bacillus sp1 and Bacillus sp2, supported by the high population treatment of A4 during each storage. Liquid biofertilizers have many advantages compared to solid biofertilizers, including having a higher number of microbial cells, longer shelf life, greater protection against the environment and better effectiveness in the field. This study can provide information on the density of liquid biofertilizer bacteria using environmentally friendly coconut water media for the community by using phosphate-solubilizing bacteria (Bacillus spp.) from West Kalimantan peat soil.

This study aims to improve the learning motivation of fourth-grade students of SDN 3 Jambu in Javanese language subjects, especially in Javanese script material, through the implementation of the Teams Games Tournament (TGT) learning model combined with the use of flash cards. The background of this study is the low learning motivation of students as seen from the lack of active participation, low enthusiasm during learning, and lack of interest in the Javanese script material. These conditions have an impact on the achievement of unsatisfactory learning outcomes and an unpleasant learning atmosphere. This type of research is Classroom Action Research (CAR) which is conducted in two cycles. Each cycle consists of four stages, namely planning, implementation of actions, observation, and reflection. The subjects of the study were 20 fourth-grade students. Data collection techniques were carried out using observations of student activities, interviews with teachers and students, documentation of learning activities, and evaluation tests to measure learning outcomes at the end of each cycle. Data analysis was carried out descriptively qualitatively and quantitatively. The results of the study showed a significant increase in student learning motivation after the implementation of the TGT learning model assisted by flash cards. This can be seen from the increasing activeness of students in groups, their enthusiasm in participating in educational games, and the results of learning evaluations that show a positive trend from cycle I to cycle II. The TGT model, which is based on cooperation and healthy competition, creates a more lively and enjoyable learning atmosphere and stimulates active student involvement. Thus, it can be concluded that the implementation of the Teams Games Tournament learning model supported by flashcard media is effective in increasing student motivation and learning outcomes in the Javanese Language subject, Javanese Script material.

Indonesia is one of the countries with the highest levels of biodiversity in the world and possesses vast tropical forest areas that play a crucial role in maintaining the stability of global ecosystems. However, in recent decades, Indonesia’s forests have faced significant pressures due to deforestation and environmental degradation, which have broad impacts on ecological functions, climate balance, and the socio-economic lives of communities. This study aims to examine the role of biodiversity and ecological adaptation mechanisms in maintaining the stability of Indonesia’s forest ecosystems through a literature review approach. The findings show that deforestation directly affects biodiversity decline, habitat fragmentation, disruption of hydrological systems, increased erosion, and carbon emissions. Additionally, illegal activities such as logging and mining exacerbate environmental degradation. Biodiversity is proven to be an important factor in enhancing ecosystem resilience to disturbances, including climate change. Adaptation mechanisms such as the presence of bioindicator species, the formation of ecological corridors, and community participation in conservation can strengthen ecological resilience. Rehabilitation of degraded areas and the implementation of sustainable governance policies are necessary to restore the ecological functions of forests. This study emphasizes the importance of a multidisciplinary and collaborative approach in conservation strategies, supported by strong scientific, social, and institutional frameworks to ensure the sustainability of Indonesia’s forest ecosystems in the future.

Therefore, role playing has proven to be an effective learning approach in teaching noble moral values in Islamic secondary schools.

Petrochemical-based synthetic plastics pose significant environmental concerns due to their non-biodegradable nature. Bioplastics, particularly those derived from corn starch, offer a promising alternative because of their biodegradability and renewable origin. This article presents a narrative review analyzing the effects of various additives on the characteristics of corn starch-based bioplastics, including tensile strength, water absorption, and biodegradability. The review focuses on scientific publications from 2015 to 2025.  Three types of additives were examined: cellulose fibers, graphene oxide (GO), and polyvinyl alcohol (PVA). The results show that the combination of starch and PVA with glycerol yields the best overall performance, achieving the highest tensile strength (1.8 MPa), moderate water resistance 60%, and rapid biodegradation within 6–10 days. While cellulose improves mechanical properties, it tends to slow down the degradation rate. GO provides only slight enhancements in mechanical and water-resistant properties. Overall, the starch–PVA blend appears to be the most promising formulation for developing eco-friendly and applicable bioplastics in the future.
