The Perintis Lake area in Bone Bolango Regency, Gorontalo Province, faces a growing conflict between tourism investment and environmental conservation. This study aims to analyze the impact of tourism infrastructure development on the lake’s ecosystem, highlight the importance of conservation, and provide strategic recommendations for sustainable tourism development. Using a qualitative-descriptive approach, the research is based on field observations, literature review, and regional policy analysis. Findings show that unregulated investment activities, particularly constructions along the lake's buffer zone, have led to environmental degradation, such as water pollution, habitat loss, and ecological imbalance. Conservation efforts remain fragmented and lack integration into broader development planning. The study recommends the implementation of sustainable spatial planning policies, stricter environmental regulations, and active community involvement. Collaborative governance between local authorities, private investors, and environmental stakeholders is essential to ensure that economic development aligns with ecological preservation. Striking a balance between investment and conservation is key to maintaining Perintis Lake as a resilient ecotourism destination for future generations.

Ferns are low-level plants whose distribution is quite wide and are often found on the campus of UIN Sunan Gunung Djati Bandung. The aim of this research is to determine the calcification and relationships of ferns that live in the campus area using direct exploration methods by observing their morphological characteristics. The data from morphological observations is then processed into a dendogrm so that relationships can be identified and read using the similarity index formula. The results of this research show that 2 divisions of ferns were found, namely pteridophyta and traceophyta. In the pteridophyta division, 1 class, 2 orders, 6 families and 9 species were found. Meanwhile, in the traceophyta division, 1 class, 1 order, 1 family and 1 species were found. The results of the kinship analysis show that the 10 species of ferns can be divided into 2 large groups based on 16 morphological traits. The relationship between species is measured using the Sorensen similarity index, which shows that several species have a relationship that is very close (? 75%), close (51-74%), not close (26-50%), and very not close (? 25%). For example, Pityrogramma calomelanos and Adiantum capillus are very closely related with a similarity index of 87.5%, while Pyrrosia piloselloides and Phymatosorus scolopendria are not closely related with a similarity index of 43%.

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.

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.

This study investigates the influence of Fear of Missing Out (FoMO), a psychological phenomenon amplified by social media platforms such as Instagram and TikTok, on the behavior of each individual. Focusing on the case of Agroeduwisata MarkazKomobid in Serang Regency, this study uses qualitative methods to explore how digital exposure shapes travel motivation. Referring to insights on digital culture, the psychological effects of FoMO, and social media-driven tourism strategies, this analysis reveals that online trends often serve as social benchmarks, pressuring individuals to engage in experiences that are considered popular or viral. These findings emphasize the strategic importance of social media in creating an attractive destination image and driving visitor interest, especially for active social media users.

This study explores the synergy between investment decisions and sharia compliance validation in developing financial products for SMEs, with a case study of PT Syariah Sejahtera. The research emphasizes the importance of integrating halal principles into investment analysis using methods such as Payback Period (PBP), Net Present Value (NPV), and Internal Rate of Return (IRR). The validation process involves systematic steps, including initial identification, legal analysis, consultation with the Sharia Supervisory Board, and issuance of fatwas to ensure products comply with Islamic law. Results demonstrate that effective integration enhances product credibility, attracts market interest, and contributes to economic and social welfare, especially in the agricultural SME sector. The findings suggest that combining financial analysis with strict halal validation fosters sustainable growth of sharia-based financial services, reinforcing trust and regulatory compliance.

This study aims to evaluate whether numerical results from IRE exams can accurately reflect students' overall spiritual comprehension. Through both quantitative and qualitative analysis, the study finds that relying solely on test scores is insufficient to assess students’ faith and spiritual insight. Significant differences in learning outcomes between schools suggest that variations in teaching methods and assessment systems contribute to these disparities. Interviews with students and teachers reveal that IRE exams, which tend to emphasize memorization, fall short in uncovering deeper understanding of religious values. In contrast, assessment approaches that are more relevant to everyday life, encourage reflection, utilize narrative methods, and observe student behavior are perceived as more effective. Therefore, an ideal model for assessing Islamic Religious Education should integrate both cognitive evaluation and spiritual reflection through a comprehensive, holistic approach. By combining written assessments with contextual inquiry, personal reflection, and behavioral observation, educators can gain a more accurate and authentic picture of students’ religious understanding. Such a multifaceted evaluation system not only enhances the relevance of PAI but also supports the formation of students who genuinely embody Islamic values in their daily lives.

This study aims to evaluate the effect of grafting and budding techniques on the growth and success of avocado (Persea americana) plant propagation. Grafting and budding techniques are vegetative methods commonly used in horticultural plant propagation to maintain the genetic quality of the parent plant. The study was conducted using avocado plants with grafting and budding techniques on the rootstock. The parameters observed included the level of success of unification (compatibility rate), shoot growth rate, survival percentage, and growth in stem diameter and plant height during a certain period. The results showed that the grafting technique provided a higher success rate than the budding technique on certain varieties, with a survival percentage reaching 85%. However, the budding technique showed advantages in the parameter of shoot growth rate, especially on varieties with specific or better environmental adaptation. This study shows that choosing the right propagation technique, depending on the characteristics of the variety and environmental conditions, is a key factor in supporting the success of avocado plant propagation. These findings are expected to be a reference for farmers and researchers in optimizing the production of high-quality avocado seedlings.

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.
