Abstract

Public perception generally limits the understanding of probiotic functions in broiler chickens to solely replacing the role of antibiotics, overlooking their other potential benefits. Therefore, a comprehensive systematic literature review (SLR) is warranted to elucidate the multifaceted advantages of probiotic addition on the development and overall performance of broiler chickens. This SLR adhered to the PRISMA guidelines. A total of 84 articles from 35 Scopus-indexed journals were screened and included following the PRISMA stages. The selected articles were subsequently visualized using covidence. The findings revealed eight key benefits of probiotics in broiler chickens: 1) enhanced growth performance; 2) improved gut health; 3) enhanced immune performance; 4) improved metabolic status; 5) reduced stress levels; 6) improved meat, carcass, and bone quality; 7) antibiotic replacement; and 8) enhanced synergistic effects with other feed additives Systematic Literature Review (SLR): Pengaruh Penggunaan Probiotik Terhadap Produktivitas Dan Tingkat Pertumbuhan Ayam Broiler ABSTRAK: Masyarakat pada umumnya mengetahui bahwa fungsi probiotik hanya bisa menggantikan peran antibiotik di ayam broiler, namun tidak mengetahui manfaat lain dari probiotik. Oleh karena itu perlu ada kajian SLR yang mengupas secara komprehensif manfaat suplementasi probiotik terhadap pertumbuhan dan performansi  ayam broiler. SLR yang dibuat berpadoman pada panduan prisma. Ada 84 artikel dari 35 jurnal terindkes scopus yang tersaring dalam tahapan prisma. Artikel yang tersaring kemudian divisualisasikan dengan covidence. Hasilnya ada 8 manfaat probiotik terhadap ayam broiler yaitu 1) meningkatkan performansi pertumbuhan 2) Memperbaiki kesehatan usus 3) meningkatkan performasi Imun 4) meningkatkan status metabolik 5) pengurangan tingkat stress 6) peningkatkan kualitas daging, karkas dan tulang 7) pengganti antibiotik dan terakhir 8) Meningkatkan efek sinergitas dengan zat adiktif lainnya.

Abstract

This study evaluates the Islam-oriented 9E Learning Cycle for enhancing scientific literacy and self-confidence in secondary school biology. Using a quasi-experimental pretest–posttest control-group design, two Grade X classes participated: the experimental class learned via the 9E model infused with Islamic values, while the control class received discovery learning. Data were collected through PISA aligned literacy tests and questionnaires, validated self-confidence scales, and observation sheets, all demonstrating reliability (Cronbach’s α > .70). Independent t-tests and correlation analyses showed that the experimental group achieved higher posttest scores and larger normalized gains in scientific literacy (N-gain = 0.70, high) and self-confidence (N-gain = 0.69, moderate). Explained-variance estimates indicated contributions of 17.3% to literacy and 14.8% to self-confidence. Findings suggest that integrating spiritual ethical dimensions within a structured inquiry cycle strengthens conceptual mastery and nurtures affective development, positioning the Islam oriented 9E model as a holistic pedagogical strategy for curriculum reform and teacher professional development in faith-based contexts. Menumbuhkan Literasi Sains dan Rasa Percaya Diri melalui Siklus Pembelajaran 9E Berorientasi Islam dalam Pendidikan Biologi ABSTRAK: Penelitian ini mengevaluasi efektivitas Learning Cycle 9E berorientasi Islam dalam meningkatkan literasi sains dan kepercayaan diri pada pembelajaran biologi di sekolah menengah. Dengan desain kuasi-eksperimental pretest–postest control grup design, kelas eksperimen belajar melalui model 9E yang orientasi nilai-nilai Islam, sedangkan kelas kontrol menggunakan discovery learning. Data dikumpulkan melalui tes dan kuesioner literasi sains framwork PISA 2025, skala kepercayaan diri tervalidasi, serta lembar observasi; seluruh instrumen menunjukkan reliabilitas baik (Cronbach’s α > .70). Uji t independen dan analisis korelasi menunjukkan kelas eksperimen meraih skor pascates lebih tinggi dan gain ternormalisasi lebih besar pada literasi sains (N-gain = 0,70; tinggi) dan kepercayaan diri (N-gain = 0,69; sedang). Estimasi variasi yang dijelaskan mengindikasikan kontribusi 17,3% terhadap literasi dan 14,8% terhadap kepercayaan diri. Temuan ini menyiratkan bahwa integrasi dimensi spiritual etis dalam siklus inkuiri terstruktur memperkuat penguasaan konseptual sekaligus menumbuhkan aspek afektif, sehingga model 9E berorientasi Islam layak diposisikan sebagai strategi pedagogis holistik bagi reformasi kurikulum dan pengembangan profesional guru di konteks pendidikan berbasis keagamaan.

Abstract

This study aims to inventory the types of food crops growing around tailings ponds and to quantify mercury concentrations in food crop tissues growing in the area around the gold mine. The samples taken are plants consumed by residents. Mercury content testing uses a mercury analyzer. The results of the study showed that from 4 observation locations, a total of 11 types of food crops were found, all of which contained mercury (Hg) with a concentration range of 0.01-0.54 mg/kg. Similarly, the soil as a growing medium contains quite high levels of mercury at location 1, namely 54.36 mg/kg, and the lowest at location 3 at 0.12 mg/kg. The concentration of mercury in vegetable leaves is much higher than in other organs such as tubers, flowers, and fruits. Furthermore, to plant plants for consumption, it is best to pay attention to the condition of the growing medium, as a prevention of heavy metal (mercury) contamination, such as the environment (air, soil, water) that is far from waste retention ponds or waste discharge streams containing heavy metals (mercury). Analisis Konsentrasi Merkuri pada Tanaman Pangan di Sekitar Tambang Emas Kabupaten Lebong ABSTRAK: Penelitian ini bertujuan untuk menginventarisasi jenis tanaman pangan yang tumbuh disekitar kolam penampungan limbah (tailing) dan untuk mengkuantifikasi konsentrasi merkuri dalam jaringan tanaman pangan yang tumbuh di area sekitar tambang emas. Sampel yang diambil merupakan tanaman yang memang dikonsumsi oleh warga setempat. Uji kandungan merkuri menggunakan mercury analyzer. Hasil penelitian menunjukkan dari 4 lokasi pengamatan, ditemukkan Sebanyak 11 jenis tanaman pangan yang semuanya mengandung merkuri (Hg) dengan kisaran konsentrasi 0,01-0,11 mg/kg. Demikian pula, tanah sebagai media tanam mengandung kadar merkuri yang cukup tinggi di lokasi 1, yaitu 54,36 mg/kg, dan paling rendah dilokasi 3 sebesar 0,12 mg/kg. konsentrasi merkuri dalam daun sayuran jauh lebih tinggi dibandingkan organ lain seperti tuber, bunga, dan buah. Selanjutnya, untuk menanam tanaman yang akan dikonsumsi sebaiknya memperhatikan kondisi media tumbuh, sebagai pencegahan dari kontaminasi logam berat (merkuri), seperti lingkungan (udara, tanah,air) yang jauh dari kolam penampungan limbah maupun aliran pembuangan limbah yang mengandung merkuri.

Abstract

Macaca fascicularis is a diurnal primate that lives in social groups. In Taman Nasional Way Kambas, particularly in the Elephant Training Center area, long-tailed macaques are frequently observed interacting with tourists, and such interactions through ecotourism activities are suspected to influence their natural behavior. Therefore, research on their daily behavioral patterns is essential as part of conservation efforts. Observations were conducted using the scan sampling method over a 30-day period during morning (06:00–10:00 WIB) and afternoon (16:00–18:00 WIB) hours at 5-minute intervals. The results indicate that feeding was the predominant daily behavior (42%), whereas mating was the least frequently observed (2%). Overall, Macaca fascicularis in the Elephant Training Center area of Taman Nasional Way Kambas still maintain their natural behaviors but have begun to show adaptations to human presence that may potentially alter their long-term activity patterns. Perilaku Harian Monyet Ekor Panjang (Macaca fascicularis) Di Kawasan Pusat Latihan Gajah Taman Nasional Way Kambas ABSTRAK: Macaca fascicularis merupakan primata diurnal yang hidup dalam kelompok sosial. Di Taman Nasional Way Kambas, khususnya di kawasan Elephant Training Center, monyet ekor panjang sering diamati berinteraksi dengan wisatawan, dan interaksi tersebut melalui aktivitas ekowisata diduga dapat memengaruhi perilaku alaminya. Oleh karena itu, penelitian mengenai pola perilaku harian monyet ekor panjang menjadi penting sebagai bagian dari upaya konservasi. Pengamatan dilakukan menggunakan metode scan sampling selama 30 hari pada waktu pagi (06.00–10.00 WIB) dan sore hari (16.00–18.00 WIB) dengan interval pengamatan setiap 5 menit. Hasil penelitian menunjukkan bahwa perilaku makan merupakan aktivitas harian yang paling dominan (42%), sedangkan perilaku kawin merupakan yang paling jarang diamati (2%). Secara keseluruhan, Macaca fascicularis di kawasan Elephant Training Center Taman Nasional Way Kambas masih mempertahankan perilaku alaminya, namun mulai menunjukkan adaptasi terhadap keberadaan manusia yang berpotensi memengaruhi pola aktivitas jangka panjangnya.
