Abstract

Turmeric (Curcuma domestica Val) is one of the agricultural commodities being developed by the Jambi Province of Indonesia. However, despite the high value of turmeric, its productivity in Jambi Province is low. This is because the crop is mostly cultivated in marginal lands dominated by Inceptisol, which has low fertility and low water availability. Organic mulch and chicken manure have the potential to be used to improve soil water availability and crop yield. This research aimed to evaluate the effect of organic mulch cover and chicken manure on soil water availability and turmeric yield. The treatments tested were combinations of various percentages of organic mulch cover (30%, 60%, and 90%, and chicken manure dosage (0, 5, 10, and 15 t ha-1). The twelve treatment combinations were arranged in a randomized block design with three replications. The results showed that the combination of the percentage of organic mulch cover and chicken manure dosage affected soil organic matter content, soil bulk density, soil pore size distribution, soil water availability, and turmeric yield. The application of 30% cover of organic mulch and 10 t ha-1 of chicken manure was found to be the best combination to improve soil available water and turmeric yield. The regression analysis results showed that soil bulk density, organic carbon, fast-drainage pores, and slow-drainage pores simultaneously affected the soil water content, with an R2 value of 0.85. The results of this study proved that soil available water is also closely correlated with turmeric yield.

Abstract

This Community Service activity was carried out at SMP Negeri 13 Pontianak, West Kalimantan, based on the growing exposure of misleading information that students can easily access in the current digital era. Students at the lower secondary school level are in an early adolescent transition phase, making them vulnerable to receiving and distributing information without having adequate skills to assess its reliability. The activity aimed to raise awareness of the risks of false information, introduce ways to evaluate the quality of information through considerations of timeliness, content relevance, source authority, data accuracy, and communicative purpose, and develop critical thinking skills in understanding various digital content they encounter. The implementation consisted of interactive presentations, group discussions, simulated video viewing, hands-on practice using fact-checking sites, and the creation of digital campaign posters as practical application. All activities carried out on April 25, 2025 were attended by 33 students divided into small groups to facilitate guidance. The results showed a significant improvement in digital literacy skills, indicated by an increase in the average understanding score from 67.88 at the beginning to 90.00 at the end. Each group successfully produced a digital campaign poster that was published through the school’s social media as a form of contribution to promoting responsible information sharing. The main outputs, including the final report and published news coverage, were completed, while additional outputs such as a submitted scientific article and a copyrighted digital module were also produced. This activity demonstrates that engaging students directly in training strengthens their critical awareness and encourages active participation in nurturing a healthier information ecosystem.

Abstract

This study aims to examine the symbolic structure and cosmological meanings embedded in the healing mantras of the Dayak Seberuang community in Gernis Jaya Village, Sepauk District, Sintang Regency. The research employs a descriptive qualitative method using the semiotic framework of Charles Sanders Peirce, focusing on the classification of signs into icons, indexes, and symbols. The data consist of eleven healing mantras recited by ritual practitioners and were analyzed through stages of sign identification, semiotic classification, meaning interpretation, and cultural contextualization. The findings reveal that the mantras function not merely as healing formulas but as a cosmological representation system that perceives illness as a disruption in the relationship between humans, spirits, and nature. Dominant symbols include the representation of spirits (antU), the concept of “tawar” as a marker of healing, the color black, sacred numbers, and medicinal plants such as muŋah and buŋkaŋ. Within Peirce’s framework, plants and herbal elements function as icons, symptoms of illness as indexes, and lexical terms such as pederak, sawan, and datai dara/bujaŋ as culturally constructed symbols. The study contributes to the development of semiotic analysis based on the icon–index–symbol classification in the study of Dayak oral literature and integrates textual and anthropological approaches in understanding mantras as cultural sign systems grounded in local wisdom.
