Abstract

General Background: Bullying, as a persistent form of intentional oppression and violence, has become an escalating problem in schools, negatively affecting students’ academic and social development. Background (Specific): In the elementary school context, children often lack the resilience to face bullying, thus requiring character education rooted in moral and religious values. Knowledge Gap: Previous studies have explored patience in Islamic teachings generally, yet limited research has contextualized the story of Prophet Yusuf as a medium to cultivate patience specifically in addressing bullying among elementary students. Aim: This study seeks to examine whether the story of Prophet Yusuf can foster patience in 5th grade students at SDN Tales 2 in responding to bullying. Results: Using qualitative methods through interviews, observations, and documentation, findings reveal that storytelling about Prophet Yusuf inspires students to endure bullying experiences with patience and refrain from retaliation. Novelty: The integration of Qur’anic narratives into character formation provides a contextual and practical approach to reducing negative behaviors in schools. Implications: The study suggests that incorporating religious storytelling in educational settings not only enriches moral education but also offers an effective strategy for fostering resilience and patience in young learners against bullying. Highlights: Story of Prophet Yusuf fosters patience against bullying. Religious storytelling strengthens character education in elementary schools. Novel approach links Qur’anic values with anti-bullying strategies. Keywords: Character Formation, Patience, Bullying, Elementary Students, Prophet Yusuf

Abstract

The prevalence of stunting in Bakalaeng Village, Sangihe Islands Regency, reached 68,92% among at-risk families, despite the area's abundant fishery potential. The main issue lies in the low diversification of fish processing, leading to minimal consumption of fish as a protein source. This community service program aimed to empower the Family Welfare Empowerment organization through capacity building in the diversification of fishery products, as an effort to help reduce stunting and improve family economies. The implementation method consisted of four stages: (1) participatory problem identification; (2) program presentation and negotiation; (3) facilitation and mentoring using a problem-based learning approach; and (4) evaluation and monitoring. The results showed a significant increase in the knowledge and skills of the Family Welfare Empowerment organization. The partners have been able to produce innovative processed products such as kaki naga (drum stick) and fish balls, and have shown commitment to developing micro-enterprises. The program successfully created a dual impact: improved family nutritional intake and potential income increase. The local resource-based empowerment approach is effective in addressing stunting and can be a model for other coastal areas.

Abstract

This study aims to develop rice crackers into a functional food enriched with mangrove leaves (Rhizophora mucronata) from the Sangihe Islands, Indonesia, to improve their nutritional and antioxidant capacities. Mangrove leaves were extracted and analyzed using Gas Chromatography-Mass Spectrometry (GC-MS), revealing 10 fatty acid-derived compound profiles. Rice crackers were produced by adding R. mucronata leaf pulp and evaluated for proximate composition (moisture, ash, protein, fat, carbohydrate, and energy), sensory characteristics, and antioxidant capacity. Proximate analysis showed that the rice crackers contained 12.62% protein, 18.51% fat, and 59.75% carbohydrate and complied with the Indonesian National Standard (SNI) for rice crackers regarding moisture content (5.71%). Sensory evaluation showed that rice crackers with added mangrove leaves were well accepted by panelists, with “like” to “very like” ratings for appearance, aroma, taste, and texture. The antioxidant capacity of rice crackers with the addition of mangrove leaves showed moderate activity (IC50 = 123.38 µg/mL) despite a decrease due to the frying process. This study concluded that R. mucronata leaves can be a potential functional ingredient, providing nutritional benefits and antioxidant properties in rice crackers.

Abstract

This community partnership empowerment activity empowers mothers of the Family Welfare Development Team (TP. PKK) in Tahuna District, Sangihe Islands Regency, North Sulawesi through education on diversifying processed fish products to prevent stunting. This activity was carried out in September-October 2024 in three villages focused on handling stunting: Soataloara 1, Mahena, and Santiago, Tahuna District. The purpose of this empowerment activity is to empower the TP. PKK in diversifying processed fish products to help prevent stunting in the Sangihe Islands Regency. The methods used include hearings, initial observations, determining priority programs, facilitation and assistance, and monitoring and evaluation. Activities consisted of counseling on fish nutrition and technical guidance on making processed fish products such as meatballs, nuggets, and kaki naga. The evaluation was conducted through pre and post-tests to measure the improvement of participants' knowledge. The results showed a significant increase in the knowledge and skills of TP. PKK mothers. The average knowledge score on fish nutrition increased from 57% to 87%. As for the technical guidance on processed fish products, the skills improvement was seen in the making of meatballs (64% to 90%), nuggets (62% to 86%), and dragon feet (66% to 94%). This community partnership empowerment activity succeeded in increasing the understanding of PKK women in the Tahuna Sub-district about the importance of fish consumption in preventing stunting and improving the skills of TP. PKK mothers in processing fish into products with high nutritional value.

Abstract

This article examines the socio-political dynamics of agrarian issues surrounding the recognition of customary forests in Kasepuhan Karang, Lebak Regency, Banten. The recognition of customary forests is interpreted by indigenous peoples as a political victory. The political policy of recognition provides opportunities for indigenous peoples to reclaim their customary lands that have been subjected to agrarian colonialism, although this is limited to the recognition of customary forest areas. The data presented is based on the author's periodic research, which was intensive during 2018 and 2019, and continued through various field studies in 2020, 2023, 2024, and early 2025. Field data was collected using qualitative methods, through direct observation, live-in, in-depth interviews with key informants, and focus group discussions. The findings of this research show that the state's recognition of customary forests is half-hearted, partial, and fragmentary, so that socio-agrarian conditions remain unchanged and the previous structure of agrarian inequality remains intact. The state unilaterally recognized only some of the proposed customary forests, while ignoring the social dynamics and changes in the Kasepuhan Karang community, which experienced social differentiation due to the concentration of land ownership. The ideas and recommendations proposed are to encourage agrarian reform in indigenous peoples. This is to ensure agrarian justice, which has been ignored by the existing political recognition model. Among the requirements for agrarian reform in indigenous peoples is interconnectivity between ecological aspects, tenure systems, and local socio-cultural aspects, so that its implementation is flexible and contextual, and certainly cannot be standardized.

Abstract

An earthquake that occurred on December 30, 2024 in Gresik Regency, located at 7.05° S and 112.62° E with a focal depth of 14 km and magnitude M3.3, was a shallow earthquake felt with an intensity of II–III MMI. This study aims to analyze the earthquake shaking intensity map (Shakemap), determine the earthquake source mechanism, and perform earthquake scenario modeling using the maximum magnitude based on the Indonesian Earthquake Source and Hazard Map (PUSGEN). Shakemap analysis was carried out using the BMKG Shakemap server based on accelerograph network data. Fault mechanism analysis was performed using focal mechanism software with P-wave polarity input obtained from waveform signal picking using SeisGram2K software. Meanwhile, the Shakemap scenario was generated using the ShakeMap application available at the Pasuruan Geophysical Station. The results show that the distribution of Peak Ground Acceleration (PGA) and shaking intensity is influenced not only by the distance from the epicenter but also by local geological conditions that contribute to ground-motion amplification. Source mechanism analysis indicates that the Gresik earthquake was dominated by a strike-slip faulting mechanism with a weak oblique component, interpreted as sinistral strike-slip motion along the RMKS–Tuban 3 fault zone. Scenario earthquake modeling with a magnitude of M 6.2 indicates that Gresik Regency has the potential to experience strong ground shaking with maximum intensities reaching VI–VII MMI, while surrounding areas such as Surabaya City, eastern Lamongan Regency, and western Bangkalan Regency may experience intensities up to VI MMI. These findings indicate that although the Gresik earthquake had a relatively small magnitude, the potential earthquake impact in Gresik and surrounding areas could become significant if a maximum-magnitude earthquake occurs, therefore, this study provides important information for earthquake disaster mitigation efforts.

Abstract

Mangrove plants, particularly Bruguiera gymnorrhiza, are recognized as sources of bioactive compounds. This study analyzed the chemical profiles, safety, and antioxidant activity of B. gymnorrhiza leaf extract origin Sulawesi, a biodiversity-rich Wallacean region. Research on B. gymnorrhiza leaves from Sulawesi remains scarce. GC-MS analysis identified inositol, fatty acid, ester, and terpenoid derivatives as major chemical profiles related to stress tolerance and remedial properties. ADMET predictions showed good intestinal absorption but suggested potential hepatotoxicity at high doses. Brine shrimp lethality tests revealed low acute toxicity with an LD₅₀ of 873.381 µg/mL, supporting in silico findings. The extract exhibited strong antioxidant activity (IC₅₀ 49.78 µg/mL), comparable to Vitamin E, and higher than reports from other regions. These results indicate that Sulawesi mangroves store valuable chemical compounds and serve as environmental health indicators. Combining chemical profiling, computational prediction, and experimental validation highlights their pharmaceutical potential while emphasizing the need for careful dose optimization and ecological monitoring. This study reinforces the importance of conserving Wallacean biodiversity and offers a foundation for safe, natural antioxidant commercialization. Future work should assess in vivo effectiveness, long-term toxicity, and the ecological impacts of pollutant immobilization in mangrove ecosystems.
