Abstract

Cinnamon leaves contain active compounds such as polyphenols and flavonoids which have antioxidant properties and play a role in lipid metabolism processes. This active substance is known to reduce liver fat levels and has the potential to increase the immune response in catfish. This research aims to determine the effect of adding cinnamon leaf extract to feed on liver fat levels and the health of catfish. Cinnamon leaf extract was added to the feed at five different doses, namely 0 g/kg (control), 0.5 g/kg, 1 g/kg, 2 g/kg, and 4 g/kg feed. The results of the study showed that the addition of cinnamon leaf extract to the feed reduced the fat content in the liver of catfish as seen from the decrease in fat degeneration in the liver of catfish compared to the control. Total erythrocytes, hemoglobin levels and hematocrit levels of fish treated with the addition of cinnamon leaf extract to the feed were lower and significantly different (P<0.05) compared to controls, but total leukocytes were not significantly different between treatment and control.

Abstract

Fish is a fishery product that has high nutritional value. Fish can be processed into various processed products. Processed fish products generally have the characteristic of not lasting long when stored at room temperature so that in the food processing, additives are added. Hazardous food additives that are often used in processed fish products are formalin. Formalin is a preservative that can cross-link with protein so as to prevent damage to product and can extend its shelf life. This study aims to determine the formalin content in processed fish products, namely fish meatballs and salted fish in traditional markets in Jambi City. The research method used laboratory experiments with 4 treatments and 3 replications. The results showed that the samples of fish meatballs and salted fish as a whole were positive for formalin. This shows that the food safety of processed products in traditional markets in Jambi is still low. The knowledge and awareness of the fisheries processing community about hazardous food additives is still low.

Abstract

Porphyridium cruentum has advantages in pigments and exopolysaccharides, so it has the potential to be developed in the food, pharmaceutical, nutraceutical, and cosmetic industries. Porphyridium cruentum cultivation media uses synthetic and indoors, causing high costs. This study aims to determine the growth performance of Porphyridium cruentum in different mediums and method of cultivation. The research methods used cultivating Porphyridium cruentum for 7 days with four treatments, namely indoors Guillard media (IGM), outdoors Guillard media (OGM), indoors fertilizer media (IFM), and outdoors fertilizer media (OFM. Each treatment had three replications. Growth was identified using an optical density spectrophotometer uv-vis, gravimetrically dried weight of biomass and pH adjustment during 7 days of cultivation. The result shows the best growth performance in IFM, followed by IGM, OFM, and OGM. Fertilizer media is better for the growth of Porphyridium cruentum than Guillard media. pH growth Porphyridium cruentum during cultivation 7-7.5. Indoor cultivation is better than outdoor cultivation. The highest biomass was IFM, which had the best performance in IFM with OD 0.247, pH 7, and biomass 79.6%.

Abstract

Taman Nasional Perairan Natuna merupakan salah satu kawasan konservasi laut yang dilindungi karena memiliki keanekaragaman hayati yang sangat penting dalam menjaga keseimbangan ekosistem laut serta mendukung keberlanjutan sumber daya alam perairan Indonesia. Pengelolaan kawasan konservasi memerlukan berbagai pertimbangan dan pemahaman mengenai kondisi fisik seperti adalah parameter suhu dan salinitas. Penelitian ini bertujuan untuk memberikan gambaran yang lebih komprehensif mengenai distribusi suhu dan salinitas di TNPN, khususnya di Pulau Laut. Data pada penelitian ini menggunakan data Argo Float dan akan dianalisis secara spasial dan vertikal dengan analisis stratifikasi perairan. Distribusi horizontal nilai suhu berkisar 25.99-27.31°C dan salinitas berkisar antara 33.01-33.31‰. Distribusi vertikal suhu berkisar antara 25.5-26.5°C dan 33.25-33.4‰. pada awal musim Barat terdapat lapisan homogen pada kedalaman 0-5 m dan bervariasi didaerah pesisir. Variasi nilai suhu dan salinitas diduga karena percampuran vertikal yang diinduksi oleh angin musim barat yang bergerak dengan kecepatan rata-rata 6.69 m/s. Sehingga, Taman Nasional Perairan Natuna cocok untuk dikembangkan sebagai kawasan konservasi.
