Abstract

Penggunaan fungisida sintetis sebagai agen antijamur telah banyak dilakukan, namun residunya dapat menimbulkan resistensi pada lingkungan. Oleh karena itu, pengembangan antifungi berbasis bahan alam yang aman dan efektif menjadi solusi yang yang ramah lingkungan. Daun cengkeh diketahui mengandung senyawa bioaktif seperti eugenol, flavonoid, dan tanin yang memiliki aktivitas antimikroba. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak etanol daun cengkeh dalam menghambat pertumbuhan A. niger. Metode yang digunakan eksperimen dengan rancangan posttest only control group design. Uji aktivitas antijamur dilakukan dengan metode difusi cakram pada media Potato Dextrose Agar (PDA) dengan variasi konsentrasi ekstrak sebesar 0%, 5%, 10%, 20%, dan 30%. Hasil penelitian menunjukkan peningkatan konsentrasi ekstrak berbanding lurus dengan luas zona hambat yang terbentuk. Zona hambat terluas ditemukan pada konsentrasi 30% dengan diameter rata- rata 15,0 mm (sangat kuat). Hasil ini menunjukan bahwa ekstrak etanol daun cengkeh memiliki potensi sebagai bahan aktif dalam formulasi biofungisida nabati, yang aman dan ramah lingkungan.

Abstract

Penemuan plastik telah membawa kemudahan bagi peradaban manusia karena plastik mempunyai daya tahan, fleksibilitas, dan biaya produksi yang rendah. Keberadaan plastik di lingkungan berasal dari kegiatan rumah tangga, industri, perdagangan, dan tempat umum. Hal tersebut akan berdampak dalam peningkatan sampah plastik. Proses dekomposisi plastik berlangsung sangat lambat sehingga diperlukan waktu ratusan tahun agar terdegradasi menjadi mikroplastik melalui berbagai proses fisik, kimiawi maupun biologis. Mikroplastik mempunyai ukuran kecil (<5 mm) dan memiliki berat 0,1-8,8 mg. Kekhawatiran tentang terjadinya distribusi dan toksikologi mikroplastik kini menjadi fokus perhatian publik di seluruh dunia. Saluran pencernaan diduga merupakan jalur utama masuknya mikroplastik ke dalam tubuh manusia. Tujuan penelitian ini adalah untuk mengetahui potensi risiko kesehatan pencernaan dengan adanya paparan mikroplastik. Penelitian ini menggunakan metode studi kepustakaan (library research) dan data dianalisis secara deskriptif sehingga akan diperoleh gambaran atau penjelasan dari topik yang diteliti. Berdasarkan hasil penelitian diketahui paparan mikroplastik secara terus-menerus pada manusia menimbulkan potensi risiko kesehatan pencernaan. Potensi tersebut telah dikaitkan dengan efek kesehatan pencernaan manusia seperti kerusakan saluran pencernaan, peradangan usus, dan dampak merugikan mikrobiota usus manusia. Efek tersebut masih dalam tahap penelitian tetapi bukti awal menunjukkan adanya potensi risiko kesehatan yang signifikan.

Abstract

Bongkasa Pertiwi Village, Abiansemal District, Badung Regency, is a highland area where the community maintains strong traditions, including raising Balinese pigs for both traditional and economic purposes. Balinese pigs have a genetic advantage in the form of high fat content, making them highly sought after as raw material for suckling pigs. However, since late 2021, pig farming in Bali has faced a serious threat in the form of an African Swine Fever (ASF) outbreak, which has caused mass deaths with a mortality rate of nearly 100%. This situation is exacerbated by the lack of understanding among farmers regarding disease prevention and management. This Community Service Program was implemented to address two main issues: (1) preventing the spread of ASF, and (2) developing Balinese pig fattening. The activities included outreach, training, mentoring, and the implementation of biosecurity practices in the barn. Additionally, training was provided on formulating high-fat, low-fiber feed to support optimal fattening. The results of this activity demonstrated improved knowledge and skills among farmers in implementing biosecurity measures, such as routine disinfection, pen waste management, and livestock movement restrictions. Farmers were also able to practice producing alternative feed based on local ingredients with a nutritional composition tailored to the needs of fattening Bali pigs. The resulting impacts included a reduced susceptibility to ASF, an average 12–15% increase in daily pig weight during the fattening period, and increased collective awareness among livestock groups for more professional business management. Thus, this activity not only provides a short-term solution to the ASF threat but also encourages the independence and sustainability of livestock groups in increasing Bali pig productivity, ultimately contributing to the economic resilience of village communities.

Abstract

The transformation of learning at the elementary school level requires teachers to apply instructional approaches aligned with 21st-century education demands, particularly Deep Learning–based instruction. However, preliminary observations indicated that most teachers at SDN 1 Gulingan, Badung still faced challenges in understanding the concepts, principles, and systematic implementation of deep learning in classroom practice. This community service program aimed to enhance teachers’ competencies in applying the Deep Learning approach through training, instructional design development, hands-on classroom implementation, and continuous mentoring. The implementation applied the Participatory Action Learning System (PALS) model consisting of five stages: socialization, theoretical and practical training, integration of technology to support learning, classroom mentoring, and program sustainability reinforcement through a professional learning community. The results demonstrated a significant improvement across four competency indicators: understanding of deep learning concepts (from 48% to 88%), ability to design lesson plans using the Deep Learning framework (from 42% to 81%), use of educational technology (from 55% to 90%), and classroom implementation of deep learning (from 38% to 82%). In addition, classroom observations during mentoring indicated a shift from teacher-centered to student-centered learning, characterized by increased collaborative, exploratory, and reflective student activities. The program also produced a sustainability outcome through the establishment of an Innovation-Based Teacher Working Group (KKG) as a platform for sharing best practices and continuous professional development. In conclusion, training and mentoring based on the PALS model proved effective in improving teachers’ pedagogical competence and fostering the implementation of innovative instructional practices aligned with future education demands.

Abstract

This study aims to analyze the characteristics and quality of a STEM-based science assessment instrument oriented toward the Programme for International Student Assessment (PSA) for tenth-grade students at SMA Negeri 1 Semarapura. This study used a mixed methods approach with a sequential explanatory design that integrates qualitative and quantitative analysis. The subjects were tenth-grade students in the 2025/2026 academic year. Qualitative data were collected through observation, interviews, and document studies to assess the suitability of the instrument's characteristics to the PISA scientific literacy framework, which includes aspects of context, content, and competency. Quantitative data were obtained through instrument trials to analyze item quality, including validity, reliability, difficulty level, and discriminatory power. The results showed that the developed instrument met the PISA assessment characteristics by incorporating real-world contexts, integration across STEM disciplines, and higher-order thinking skills. Quantitatively, most items had good validity, high reliability, moderate difficulty level, and adequate to good discriminatory power. However, some items needed revision to improve the instrument's quality. Thus, the developed assessment instrument is suitable for measuring students' scientific literacy and supporting the development of STEM-based assessments oriented towards international standards.
