Abstract

Climate change has triggered increased rainfall intensity and exacerbated the risk of disasters, especially landslides in the tropical hilly areas of Ambon Island. This community service activity was carried out in Karang Panjang Village, Sirimau District, Ambon City, to increase public awareness and knowledge about the impacts of climate change and preventive strategies for slope landslides. Activities include geoscience and bioengineering-based education and direct practice of planting vetiver grass (Chrysopogon zizanioides) as a natural solution for slope prevention. The evaluation results showed an increase in public understanding by 24.7% after participating in a series of socialization activities. In addition to gaining knowledge about the causes and dynamics of slope stability, residents were also equipped with skills to plant and maintain vetiver independently and sustainably. This program proves that an educational and participatory approach can be a strong foundation for community-based disaster mitigation.

Abstract

This study aims to test the elasticity properties and calculate the elastic modulus (Young's modulus) of natural rubber produced by Castilla elastica trees that grow naturally in Hila Village, Ambon Island. This plant is an alternative source of rubber that has not been widely utilized in Indonesia. The research was conducted using quantitative experimental methods in a laboratory where sap from the Castilla elastica tree was tapped, dried, and formed into uniform-sized rubber strips. Elasticity tests were carried out by applying gradual loads to each sample and measuring the increase in length due to strain. The results showed that rubber from Castilla elastica has high tensile strength but a relatively low elastic modulus, ranging from 5,416 to 16,263 N/m². This value is significantly lower than the elastic modulus of natural rubber from Hevea brasiliensis, which typically ranges between 0.32–0.42 MPa. The decrease in modulus with increasing load indicates the non-linear elastic behavior of the material. These results suggest that rubber derived from Castilla elastica is soft and has potential applications in lightweight elastic products. These characteristics indicate its potential utilization as a base material for the fabrication of lightweight elastomeric products such as flexible protective membranes, elastic adhesive coatings, soft sleeves or gaskets, and lightweight vibration-damping pads in mechanical systems.

Abstract

Lumpur di Desa Kufar, Maluku, Indonesia, merupakan lumpur hasil pengeboran minyak yang berpotensi sebagai sumber mineral sekunder bernilai ekonomi. Penelitian ini bertujuan mengkarakterisasi komposisi unsur, struktur kristal, dan fasa mineral lumpur tersebut melalui pendekatan terpadu X-Ray Fluorescence (XRF) dan X-Ray Diffraction (XRD), yang dianalisis menggunakan perangkat lunak Match 3!, Rietica, dan MAUD berbasis metode Rietveld refinement. Analisis XRF menunjukkan dominasi kalsium (Ca, 57,9 wt.%), diikuti oleh besi (Fe, 21 wt.%) dan silikon (Si, 12 wt.%), dengan unsur minor seperti Cr, V, Ba, dan Mn masing-masing <1 wt.% jauh di bawah ambang toksisitas lingkungan. Analisis XRD mengidentifikasi lima fasa mineral utama: kalsit (CaCO₃), kuarsa (SiO₂), aluminium oksida, ulvoespinel, dan grimaldi deuterate. Refinement kuantitatif dengan Rietica mengungkap dominasi kalsit sebesar 81,63%, diikuti kuarsa (6,62%), aluminium oksida (4,49%), ulvoespinel (3,89%), dan grimaldi deuterate (3,37%), dengan nilai Goodness of Fit (GoF) = 1,27 yang menunjukkan kesesuaian tinggi antara model dan data eksperimen. Analisis ukuran kristal menggunakan MAUD menghasilkan kristal kalsit berukuran 137 nm dan kuarsa 94 nm, sedangkan fasa minor tidak dapat dikuantifikasi akibat intensitas difraksi yang rendah. Temuan ini menunjukkan bahwa lumpur bor di Desa Kufar merupakan sumber CaCO₃ alami yang aman dan berpotensi dimanfaatkan sebagai bahan baku dalam industri.

Abstract

The development of digital technology demands innovation in physics learning to make it more contextual and applicable. However, in it’s implementation, learning at the Senior High School (SMA) level still faces various problems, especially in physics learning. One of the main obstacles is the abstract and mathematical nature of physics material, making it difficult for students to understand if it is only delivered through lecture methods or text-based learning. This community service activity aims to introduce Arduino microcontroller technology as a practical-based physics learning medium to improve students conceptual understanding and interest in learning. The activity implementation method is designed gradually and participatively, including preparation stages, socialization and introduction to Arduino concepts, training and physics practicum based on Arduino, as well as evaluation and follow-up. The participants consisted of 20 twelfth-grade science major students from SMA Negeri 10 Ambon. Evaluation was conducted using a questionnaire instrument to assess students perceived understanding, interest, and responses to the activity. The results showed an increase in students perceived understanding of physics concepts after the activity, with 55% categorized as “very good” and 35% as “good.” In addition, students interest and enthusiasm for Arduino-based physics learning also increased, reaching 70% in the “very good” category. These findings indicate that the use of Arduino microcontrollers is effective as an interactive and contextual physics learning medium, with the potential to improve the quality of physics education in schools.
