Abstract

Rhizophora apiculata leaf extract has benefits as an herbal supplement that can be added to feed, because it have componds like flavonoid, tannins, saponins, terpenoids, and steroids that can improve the health of jambal fish (Pangasius hypophthalmus). This research was carried out in August to October 2019. The aim of the research was to obtain the best dose of R. apiculata leaf extract added to feed to improve the health of jambal fish as seen from total erythrocytes, hemoglobin levels, hematocrit levels, and erythrocyte morphology. The method was used an experimental method with a Completely Randomized Design (CRD) one factor of four treatment levels consisting of P0: without the addition of extracts; P1: (1.5 mg/kg); P2: (1.7 mg/kg); and P3: (1.9 mg/kg) and repeated three times so that it takes 12 units of the experiment. Maintenance is carried out for 60 days in cages net with a size of 1x1.5x1 m3 out three times, at the beginning of maintenance, 30th day, and 60th day. The best dose was in the P2 treatment (1.7 mg/kg) seen in total erythrocytes 2.57x106 cells/mm3, hemoglobin level 13.13 g/dL, hematocrit value 38.43%, absolute weight growth 38.93 g, survival rate 97,33%, and showed normal erythrocyte morphology, it was supported by water quality during the reasearch such as DO 6.4-6,9 mg/L, pH 6.1-6.8, temperature 28.2 29.50C, and ammonia 0.04-0.08  mg/L. The Blood tests were carried.

Abstract

Mangrove leaves (R.apiculata) contain flavonoid compounds, terpenoids, steroids, saponins, and tannins which function as antibacterial and can improve fish health. This research was carried out in August to October 2019. This research purpose was to know the proper dose of mangrove leaf (R. apiculata) added to the feed to improve fish health as seen from total leukocytes, leukocyte differentiation, and phagocytic activity of P. hypophthalmus. The method in this research was the experimental method using the Completely Randomized Design (CRD) with one factor, four treatment levels and three times replication, so that it takes 12 units of experiments. The treatments were P0 (feed without additional extract R. apiculata), P1, P2, and P3 feed which were given extract R. apiculata at a dose of 1,5 mg/kg, 1,7 mg/kg and 1,9 mg/kg of feed. The fish used is P. hypophthalmus size 8-10 cm with a stocking density of 50 fish/m3. Feeding three times a day at 08.00, 12.00, and 17.00. Blood testing was performed three times, namely the beginning of the 1st, 30th, and 60th day of maintenance. The results showed that the addition of extract (R. apiculata) into the feed had a significant effect on total leukocytes, leukocyte differentiation, phagocytic activity, survival rate and growth of absolute weight of P. hypophthalmus. The best dose is 1,7 mg/kg of feed with total leukocytes 11,17x104 cells/mm3,  lymphocytes 84,33%, neutrophils 6,67%, monocytes 9,00%, phagocytosis activity 35,00%, survival rate 97,33%, and absolute weight growth of 38,93g.

Abstract

The Giam Siak Kecil—Bukit Batu Biosphere Reserve (GSKBB) is a UNESCO-designated protected area in Riau Province, Indonesia. Located within Bengkalis and Siak Regencies, GSKBB is renowned for its diverse ecosystems, including coastal wetlands, mangrove forests, and peatlands. To understand the economic viability of fishing activities within this biosphere reserve, a study was conducted in November 2023 in Siak Kecil District. The research focused on local fishermen using traditional fishing methods such as cast nets, lukah (traps), and hambat (scoops). Data analysis revealed that despite the environmental challenges faced by GSKBB, fishing remains a significant source of income for many local communities. The average investment made by fishermen was IDR 34,667,375, while annual revenue reached IDR 76,052,500. After accounting for costs such as fuel, equipment maintenance, and bait, fishermen realized an average profit of IDR 52,989,502 per year. The calculated revenue cost ratio (RCR) of 3.29, greater than 1, indicates a favorable financial performance for the fishing businesses in GSKBB. This suggests that the region's natural resources can sustainably provide a viable livelihood for local communities. However, it is essential to monitor the long-term sustainability of fishing practices to ensure the preservation of GSKBB's ecosystems and the continued economic well-being of its inhabitants

Abstract

Tanah Merah Village is one of the Fourfinger threadfin fish-producing areas. Most of the population works as fishermen as the basis of their economic income. Fourfinger threadfin fish is the main fishery commodity and has high economic value, thus encouraging the sustainable use of Fourfinger threadfin resources. This research aims to analyze the product flow, information, and finance mechanism in the supply chain of fourfinger threadfin (Eleutheronema tetradactylum) from Tanah Merah Village, Tanah Merah District, Indragiri Hilir Regency. The method used was in-depth interviews with a qualitative approach. The research results show that the flow of fourfinger threadfin fish products is spread across four provinces on the island of Sumatra. The payment systems used are cash, bank transfers, and loans. The selling price of delighted fish at the fisherman level is IDR 45.000/kg, and at the end consumer IDR 55.000-70.000/kg. Five Senangin fish supply chain entities, namely fishermen, fishermen, collectors, retailers, and final consumers form 3 chain patterns. The longest chain involves five entities and the shortest three entities. The farmer's share value for fishermen is relatively high at over 60%, with the highest value in chain three at 81.8%, indicating the most efficient chain. The product, financial, and information flow mechanisms have been running well. However, coordination and information integration still need to be improved to optimize the supply chain for fourfinger threadfin fish Tanah Merah Village

Abstract

Padang City is one of the cities with a long coastline. The Padang City government has made many reforms to manage the beach area as a tourist attraction. This research aimed to determine the comparison of macrozoobenthos community structure, including species composition, species abundance, relative abundance, diversity index, similarity index, dominance index, and distribution patterns in the reclaimed and natural beaches of Padang City, West Sumatra Province. The method used was purposive sampling with sample collection using the transect method. The results of this study indicate that the water quality in Padang City, West Sumatra, is sufficiently good to support macrozoobenthos life. The highest species abundance of macrozoobenthos was found at the Reclamation Beach Station. The macrozoobenthos species found belong to 2 classes: Gastropoda and Crustacea. The Gastropoda class consists of 4 species: Babylonia spirata, Pila ampullacea, Pila occidentalis, and Nerita fulgurans, while from the Crustacea class, three species were found: Ashtoret lunaris, Hemigrapsus takanoi, and Emerita sp. Meanwhile, the lowest abundance was found at the Natural Beach Station, where the species belonging to the Crustacea class, specifically H.takanoi, was found. The species diversity of macrozoobenthos at the Natural Beach Station is considered low but moderate at the Reclamation Beach Station. Similarity at the Natural Beach Station is low, while at the Reclamation Beach Station, it is high. Additionally, there is a dominant species at the Natural Beach Station, whereas no dominant species were found at the Reclamation Beach Station. The distribution pattern of macrozoobenthos in the coastal waters of Padang City is categorized as clustered distribution

Abstract

This research was conducted in January 2024 in the waters of Lukit, Merbau District, Meranti Islands. This study aimed to analyze the total oil content and abundance of planktonic diatoms and determine the relationship between total oil content and abundance of planktonic diatoms. This study used a purposive sampling method. The sampling location was divided into three stations with three sampling points. Station 1 is in the oil company jetty area, Station 2 is in the crossing port area, and station 3 is far away from residential areas. The results of the analysis of total oil content was 0,252 ppm. The highest oil content was found at station 2, which was 0,274 ppm, and the lowest oil content was found at station 3, which was 0,222 ppm. The results of the planktonic diatom abundance ranged from 75 – 187,5 ind/L. The highest abundance was found at station 3, which was 166,67 ind/L, and the lowest was found at station 2, which was 79,17 ind/L. The results of the simple linear regression test obtained the equation y= 177,77-225,55x with the value of R² = 0,1321 and the correlation coefficient r = -0,36, which shows that higher total oil content will cause a decrease in the abundance of planktonic diatoms
