Abstract

The textile industry is a major contributor to global water pollution, releasing an estimated 280,000 tons of synthetic dyes annually into aquatic ecosystems. These dyes, particularly azo compounds, are often toxic, mutagenic, and resistant to conventional wastewater treatment methods. Microbial enzymatic degradation, especially by white-rot fungi, offers a promising eco-friendly alternative. This study aimed to optimize the production of ligninolytic enzymes—Laccase (Lac), manganese peroxidase (MnP), and lignin peroxidase (LiP)—from Coriolopsis caperata, and assess their efficiency in degrading two azo dyes: Reactive Red 21 (RR21) and Reactive Orange 107 (RO107). The fungus, isolated from the Peat Swamp Forest in Sebangau, Central Kalimantan, was cultured in a modified glucose-peptone medium enriched with veratryl alcohol. The optimization parameters included variations in time, dye concentration, and the addition of hydrogen peroxide (H₂O₂). Enzyme activity was quantified spectrophotometrically, and dye decolorization was assessed over time at different dye concentrations. Among the enzymes, Lac showed the highest activity (4938.05 U/L), followed by LiP (995.26 U/L) and MnP (246.47 U/L). These values notably exceed several previously reported benchmarks for fungal enzyme activity. RO107 demonstrated greater susceptibility to enzymatic degradation, with 83.71% decolorization achieved at 24 hours, while RR21 reached 65.71% at 48 hours. The addition of 1 mM H₂O₂ significantly enhanced decolorization, increasing RR21 and RO107 removal to 95.71% and 99.30%, respectively. These results underscore the oxidative synergy between H₂O₂ and ligninolytic enzymes, particularly LiP and MnP. Overall, the study demonstrates the potential scalability of C. caperata-based enzymatic treatment systems for textile effluent bioremediation, supporting compliance with environmental discharge regulations and contributing to sustainable wastewater management.

Abstract

The socialization and educational program on creating presentations using the Canva application was conducted at SMPN 4 Tewah, Gunung Mas Regency, Central Kalimantan, as an effort to improve students’ digital literacy and communication skills in the technological era. Canva was chosen because it is an online-based design application that is accessible, user-friendly, and offers a wide variety of attractive templates to support students’ creativity in preparing presentation materials. The main objectives of this program were to provide a basic understanding of Canva usage, train students in designing effective presentation slides, and foster their confidence in delivering ideas. The implementation method included socialization, hands-on training, and practice in creating presentations based on learning themes. The results indicated that most students were able to understand Canva’s basic functions, utilize its features, and produce more engaging and communicative presentations compared to before. Moreover, this activity increased students’ enthusiasm and motivation to learn, particularly in using digital technology to support their academic progress. Therefore, this socialization and educational program made a positive contribution to enhancing the digital competence of SMPN 4 Tewah students, while also supporting the achievement of educational goals in the digital era.

Abstract

The Green Initiative conducted in Tumbang Habaon Village, Tewah District, Gunung Mas Regency, Central Kalimantan, aimed to improve environmental awareness and strengthen community capacity in the cultivation and sustainable management of potential plant species. Using a Participatory Action Research (PAR) approach, the program involved socialization activities, technical training, and the collaborative planting of 2,000 trees, including guava, petai, and jengkol. Community members received guidance on proper planting techniques, land preparation, and plant maintenance. The activity successfully increased community understanding of environmental conservation from 40% to 80%. The planted trees showed an 85% survival rate within the first six months, supported by routine mentoring. The program also generated early economic benefits for 50 households through the introduction of productive tree species and contributed to reducing flood risks and improving local biodiversity. Challenges faced during implementation—such as limited availability of quality seedlings and initial community reluctance—were addressed through cooperation with local government stakeholders. Overall, the Green Initiative serves as a practical community service model that promotes environmental sustainability, community participation, and local empowerment, with potential for replication in other rural villages facing similar environmental issues.

Abstract

The objective of this research is to assess the adsorption capacity of activated carbon derived from meranti wood (Shore spp) for mercury (Hg) removal from liquid waste. To establish the relationship between concentration and absorbance, the method employed involves calibrating mercury concentration using calibration curves. Additionally, the effects of pH and exposure time on adsorption capacity were examined. The results indicate that activated carbon from meranti wood can significantly adsorb mercury, achieving an efficiency level of 97.610% at pH 3, with adsorption stability reached within 80 minutes at an adsorption rate of 94.30%. The conclusions drawn from this study suggest that activated carbon from meranti wood is a sustainable and effective solution for addressing mercury contamination in wastewater. It also highlights the importance of regulating pH and exposure time. This research contributes significantly to the development of environmentally friendly methods for water purification.
