Abstract

Cosmos caudatus is a herb that benefits overall health. This study aimed to determine the effect of C. caudatus leaf supplementation in feed on blood glucose levels in catfish (Pangasianodon hypophthalmus) challenged with Aeromonas hydrophila. This study was conducted from March to August 2024 at the Marine Microbiology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The method used was an experimental design employing a completely randomized design (CRD) with four treatments and three replications: negative control (NC, no supplementation, no infection), positive control (PC, no supplementation, with A. hydrophila bacterial infection), supplementation with C. caudatus at doses of 10 g/kg (T1), 15 g/kg (T2), and 20 g/kg (T3) of feed, all tested against A. hydrophila. The fish fry used weighed 5.00 ± 1.00 g and were reared for 75 days in 100-L tanks integrated with an aquaponics system. The fish were fed the experimental feed for 60 days before challenge with A. hydrophila bacteria (10⁸ CFU/mL, intramuscular injection) and continued for 14 days after challenge. Blood glucose levels were measured at the beginning (day 1), day 30, pre-challenge (day 60), and post-challenge (day 75). The results showed that adding basil leaves to the feed affected blood glucose (P<0.05). The addition of C. Caudatus leaves maintained glucose homeostasis within the range of 68.33±10.59-79.67±7.77 mg/dL. These findings indicate that C. Caudatus supplementation effectively prevents hyperglycemia caused by A. hydrohila infection in striped catfish and suggest its potential as a natural immunostimulant and metabolic modulator in aquaculture

Abstract

Intensifikasi akuakultur sering kali diikuti dengan peningkatan stres dan kerentanan organisme budidaya terhadap penyakit, sehingga penggunaan antibiotik sintetis menjadi praktik umum. Namun, penggunaan secara berlebihan menimbulkan berbagai permasalahan, seperti resistensi bakteri, residu pada produk perikanan, dan dampak negatif terhadap lingkungan. Oleh karena itu, diperlukan alternatif pengendalian penyakit yang lebih aman dan berkelanjutan, salah satunya melalui pemanfaatan fitofarmaka. Daun kenikir (Cosmos caudatus Kunth) merupakan tanaman yang diketahui mengandung berbagai senyawa bioaktif, seperti flavonoid, fenolik, saponin, tanin, dan alkaloid, yang berpotensi sebagai imunostimulan alami. Kajian ini bertujuan untuk menelaah potensi daun kenikir sebagai imunostimulan dalam akuakultur berdasarkan studi-studi terdahulu. Metode yang digunakan adalah kajian literatur dengan mengumpulkan dan menganalisis hasil penelitian terkait kandungan fitokimia, aktivitas biologis, mekanisme kerja, serta aplikasi daun kenikir pada organisme akuakultur. Hasil kajian menunjukkan bahwa senyawa bioaktif daun kenikir memiliki aktivitas antioksidan, antibakteri, dan imunomodulator yang mampu meningkatkan respons imun nonspesifik, ketahanan terhadap penyakit, pertumbuhan, serta sintasan ikan dan udang budidaya. Dengan demikian, daun kenikir berpotensi dikembangkan sebagai alternatif fitofarmaka yang aman, efektif, dan ramah lingkungan untuk mendukung sistem akuakultur berkelanjutan, meskipun masih diperlukan penelitian lanjutan terkait dosis optimal, metode aplikasi, dan keamanan jangka panjang

Abstract

Waduk PLTA Koto Panjang merupakan infrastruktur nasional yang memiliki fungsi multidimensional sebagai pembangkit listrik, area perikanan, dan kawasan pariwisata di Provinsi Riau. Tekanan hidrologis yang meningkat akibat intensitas curah hujan tinggi, degradasi tutupan hutan di wilayah hulu Daerah Aliran Sungai Kampar, dan perubahan iklim berpotensi mengubah karakteristik fisika-kimia perairan waduk. Penelitian ini bertujuan untuk menganalisis kualitas air Waduk PLTA Koto Panjang berdasarkan parameter suhu, pH, dan oksigen terlarut, serta mengevaluasi status kualitas perairan berdasarkan baku mutu air nasional. Penelitian dilakukan pada bulan September-Oktober 2024 menggunakan metode survei dengan pengukuran in situ setiap 10 hari sekali selama 60 hari. Hasil penelitian menunjukkan suhu air berkisar 28-31°C, nilai pH 6-7, dan konsentrasi DO 6,1-7,4 mg/L. Ketiga parameter tersebut masih memenuhi baku mutu air kelas II untuk air danau dan sejenisnya. Simpulan, kualitas air Waduk PLTA Koto Panjang masih dalam kondisi baik dan memenuhi standar baku mutu nasional untuk mendukung fungsi ekologis dan ekonomisnya. Hasil kajian ini dapat menjadi baseline data untuk pemantauan kualitas air jangka panjang serta dasar ilmiah dalam penyusunan strategi pengelolaan waduk yang berkelanjutan dan adaptif terhadap perubahan lingkungan

Abstract

The Indo-Pacific region is the global center of marine biodiversity, home to more than 30% of the world's marine species. The order Decapoda, which comprises more than 17,000 species, plays significant ecological and economic roles in this region. This literature review aims to synthesize current knowledge on the genetic diversity and population structure of Decapoda in the Indo-Pacific and to identify the factors influencing these patterns. Molecular studies employing genetic markers such as mitochondrial DNA (mtDNA), microsatellites, and genomic sequencing indicate that Indo-Pacific Decapoda populations generally exhibit high haplotype diversity with relatively low nucleotide differentiation. Several factors, including larval dispersal capability, the duration of the planktonic phase, geographic and oceanographic barriers, and local adaptation to environmental conditions, shape population structure. Anthropogenic activities, particularly overexploitation, have led to declines in effective population size and genetic erosion in several commercially important species, such as Penaeus monodon and Scylla serrata. This review highlights the importance of integrating genetic data into sustainable fisheries management, including ecosystem-based stock assessment, periodic genetic monitoring, and the incorporation of genetic considerations in aquaculture and restocking programs to ensure the long-term sustainability of Decapoda populations in the Indo-Pacific region.

Abstract

Thalassemia is an autosomal recessive genetic disorder that remains a significant public health concern in Indonesia; consequently, early detection of carriers is crucial to prevent the birth of children with thalassemia major. This study aims to analyze the risk of thalassemia among Biology students at the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Riau, utilizing a simplified laboratory screening approach. The research involved 30 students who participated in genetic risk questionnaires, hemoglobin level assessments using digital hemometers, and erythrocyte counts via hemocytometers. The findings revealed a questionnaire risk score of 0.07 (categorized as very low), a mean hemoglobin level of 12.73 g/dL, and an erythrocyte count of 5.22 million cells/µL, both of which fall within normal physiological ranges. These results indicate that the risk of thalassemia among Biology students at FMIPA Universitas Riau is remarkably low. Simple screening through questionnaires, hemoglobin levels, and erythrocyte counts can serve as an effective method for both educational purposes and the preliminary screening of thalassemia carrier risk in students.
