Natural fiber based composite materials are increasingly being developed as an environmentally friendly alternative to synthetic fiber-based composites. This study aims to characterize the thermal and mechanical properties of natural fiber composite materials and evaluate their potential use as sustainable materials. Composites are made using natural fibers as reinforcement and a polymer matrix through a specific molding method. Mechanical property characterization includes tensile tests, flexural tests, and impact tests, while thermal property characterization is carried out using thermal analysis to determine the thermal stability of the material. The test results show that the addition of natural fibers has a significant effect on improving the mechanical properties of the composite, especially tensile strength and elastic modulus, compared to the unreinforced matrix. In addition, natural fiber composites show quite good thermal stability over a certain temperature range, making them suitable for non-structural applications. Based on these results, natural fiber composite materials have the potential to be developed as environmentally friendly materials that have competitive mechanical and thermal performance.

The development of rural economies based on locally superior commodities is an integral part of inclusive and sustainable development strategies. Sumberdem located in Wonosari Subdistrict, Malang Regency, possesses significant potential for the development of coffee-based ecotourism. However, this potential remains largely underutilized due to several structural and institutional constraints. Key challenges include inadequate supporting infrastructure, limited capacity of local human resources, and the absence of downstream processing for coffee products. This community engagement program implemented an adaptive approach known as the Lumintu model, rooted in the Participatory Rural Appraisal (PRA) framework. Field assessments revealed critical limitations such as poor road access to plantation areas, insufficient agricultural irrigation, and weak digital connectivity. Moreover, the capacity of village institutions—such as the Village-Owned Enterprises (BUMDesa) and coffee farmer groups—remained low, resulting in local coffee products with limited added value. The initial implementation of the program has shown promising results, particularly in strengthening institutional capacity through training on tourism business management and high–value coffee processing. Furthermore, product diversification through the development of coffee-based agrotourism and digital marketing innovations has been successfully introduced. Overall, this community engagement initiative has provided a concrete solution to rural development challenges in Sumberdem Village. Moving forward, the village is expected to strengthen its position as a sustainable coffee ecotourism destination and improve the long-term economic well-being of its residents. The proposed development model also holds the potential for adaptation and replication in other rural areas with similar characteristics, thereby supporting the broader achievement of the Sustainable Development Goals (SDGs).

Knee osteoarthritis (OA) is one of the leading causes of disability among the elderly population. This degenerative joint disease is characterized by progressive damage to the articular cartilage and structural alterations of the knee joint, resulting in pain, reduced mobility, and diminished quality of life. This Community Service Program (PKM) aimed to promote early detection of knee OA through simple radiological screening as a preventive strategy to reduce the risk of musculoskeletal disability. The activity was conducted at Asisi Church, South Jakarta, involving 87 participants aged 54–87 years (mean 70.77 ± 7.32 years). Radiological examination was performed using standard anteroposterior knee X-rays, and results were classified according to the Kellgren–Lawrence grading system. Findings revealed that 98.9% of participants exhibited radiological signs of OA, predominantly grade II (60.9%), followed by grade III (21.8%), grade I (11.5%), and grade IV (4.6%), while only 1.1% showed normal results. Female participants (74.7%) predominated across all OA grades, indicating hormonal and biomechanical influences on disease progression. The mean age increased with OA severity, supporting the degenerative theory that aging leads to decreased chondrocyte function and cartilage elasticity. In addition to screening, participants received education on weight management, muscle strengthening exercises, and injury prevention. The results demonstrate that simple radiological screening is an effective, practical, and cost-efficient community-based approach for early detection of knee OA. Integrating such preventive strategies within primary care systems could significantly reduce the burden of disability among the elderly population.

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.

The Nurul Ikhlas Mosque, also known as Surau Parak Mujua, located in Pakan Akek, Jorong Kajai, Nagari Koto Baru, Solok Regency, is an important center of religious and social activities for the local community. In June 2023, the mosque suffered a major fire that destroyed the entire structure, creating an urgent need to redesign it to be more functional, ergonomic, efficient, and adaptable to local conditions. This community service project aimed to produce an architectural design that not only met structural and functional needs but also accommodated the social aspirations and cultural values of the local community. The methods used in this project included field observations to understand the community's conditions and needs, participatory discussions with local community leaders to explore aspirations and hopes, technical drawings using AutoCAD software, and structural analysis using ETABS to ensure the building's earthquake resistance. Ergonomics were a key consideration in this design, encompassing circulation flow, room dimensions, natural ventilation, and the selection of materials that were friendly and safe for the elderly, children, and people with disabilities. The output of this activity is a variety of design documents, including floor plans, elevations, building sections, floor plans, columns and beams, and 3D visualizations that can be used as a guide for phased construction. This program demonstrates the importance of collaboration between universities and the community in responding to post-disaster infrastructure needs. This knowledge-based, participatory approach is expected to produce a final design that is appropriate to real needs and the local context, and supports better and more sustainable post-disaster recovery.

Character in the sense of attitude or behavior is closely related to language, and this relationship is logical or structural because language is a reflection of a person's attitudes and behavior.  Language is a symbol of human existence that can be known about their desires, educational background, customs, even their region or country of origin.  When someone communicates by choosing polite words and expressions, that person will use good sentences. Providing direction and socialization about positive language attitudes can improve language skills and foster polite and polite character among teenagers. This community service activity was held at youth youth organization Rt.001/Rw.004 Tanah Baru, Beji, Depok City, West Java. The way to select partners is based on survey and interview results, namely that the majority of teenagers still often use slang and viral language that is not educational. The method of implementing this activity is education as well as direction and socialization. The results of this community service activity are Karang Taruna youth have gained knowledge and experience regarding polite and polite character through positive language attitudes so that it will really help teenagers in socializing with their surrounding environment.
