Abstract

The aim of carrying out the research is to determine the abundance and diversity of phytoplankton. The method used in this research is a survey method, namely data collection, documentation, and direct observation in the field. Samples were analyzed at the Marine Biology Laboratory of Riau University. The results of the research show that there are six types of phytoplankton found in the waters of Teluk Lecah Village, Rupat District, Bengkalis Regency, namely Synedra sp, Dactylococcopsis sp, Nitzschia sp, Tribonema sp, Cylindrotheca sp, and Rhizosolenia sp. The first highest phytoplankton abundance was at station II, with an abundance of 0.1660, followed by the second highest phytoplankton abundance at station I, namely the residential area, with an abundance of 0.1494 Ind/L, while the lowest phytoplankton abundance was at station III, namely at the harbor with an abundance of 0. ,0996 Ind/L. The species diversity index at stations I and III, H' > 3, means the level of species diversity is high and the water conditions are not polluted. At station II, 1 ≤ H' ≤ 3 means the level of species diversity is moderate, and the water conditions are lightly polluted. It can be concluded that the H' value still meets the criteria. The species diversity index at all stations, E > 0.5, means that the uniformity of organisms is in balance, and there is no competition for certain places or food. It can be concluded that the E value also meets the criteria. Species dominance index at all stations, D < 0.5 means no dominant species exists

Abstract

Snakehead fish (Channa maruliodes) is a freshwater fish that is increasingly popular among ornamental fish enthusiasts, especially because of its beautiful colors. Color brightness is an important factor in the culture of snakehead fish. This study aims to evaluate the effect of astaxanthin addition on increasing the color brightness of snakehead fish. This study used a completely randomized design (CRD) experimental method consisting of 4 treatments with five replications. The treatment used was the addition of Astaxanthin (AST) with doses of 0% (AST0), 1% (AST1), 3% (AST3), and 5% (AST5). The snakehead fish used had a weight size between 30.4-30.8 g/individual. The parameters measured in this study were the increase in color brightness, growth, feed conversion and efficiency, and the quality of the maintenance media. The results showed that the addition of astaxanthin in the feed significantly affected the level of color brightness, growth, and feed utilization of snakehead fish (P <0.05). The best addition of astaxanthin was obtained in the AST5 treatment with a TCF value of 5.17, total carotenoids (136.68 ppm), absolute weight (23.00 g), absolute length (3.10 cm), specific growth rate (78.00%), feed conversion (4.35), and feed efficiency of 23.00%. These findings indicate the potential of astaxanthin in improving the quality of catfish culture

Abstract

Carocok Tarusan Fishing Port is one of the fishing ports in West Sumatra Province and is a place for fishing activities in Pesisir Selatan Regency with high productivity. Factors that affect the productivity of fishermen include social and economic factors, such as the amount of capital, number of ships, number of workers, distance traveled at sea, and experience. The fishing fleet commonly used is Bagan, with as many as 171 units. Bagan ships in the Carocok Tarusan are dominated by ships measuring ≤30 GT, as many as 162 ships, while those measuring >30 GT are nine ships widely used by fishermen in the Carocok Tarusan Waters are ships measuring ≤30GT. This study aimed to determine the productivity of Bagan Perahu catches based on differences in ship size. This study was conducted from July 2023 to August 2023. The method used in this study was the survey method, with direct observation in the field, conducting interviews with fishermen, and recording the catch using a bagan ship. The types of fish caught using Bagan are Anchovi, Mackerel Scad, and Mackerel Tuna (main catch). Peperek fish, skipjack tuna, Indian Mackerel, Selar fish and Squid (bycatch). Based on the study's results, it can be concluded that in the waters of the Carocok Tarusan, Anchovies are the most commonly caught catch using a boat lift net. Ships measuring 1-10 GT have a higher productivity value than ships measuring 11-20 GT and ships measuring 21-30 GT. With a correlation value (R) approaching 1, the relationship between the dependent variable and the independent variable is stated to be very strong. Meanwhile, the results of multiple linear regression show that 81.14% is influenced by the independent variables (trip, ship size (GT), crew, fuel, and logistics).

Abstract

Waters in Parit Keladi Village have potential fish resources that cannot be developed due to household and agricultural waste contamination. This study aims to analyze water quality and plankton composition in the waters of Parit Keladi Village for freshwater fish farming. The study used a survey method in three locations, namely waters upstream, around residential areas, and downstream. Water quality parameters analyzed were temperature, depth, brightness, salinity, IDS, DO, BOD, COD, ammonia, nitrite, and nitrate. Plankton species, density, and biological index were analyzed. The results showed that the three locations' temperature, salinity, brightness, IDS, DO, COD, ammonia, nitrate, and nitrite met the national water quality standards for freshwater fish farming. However, BOD and depth values still did not meet the standard values. Planktons found consisted of 29 phytoplankton species and I zooplankton species with a total density of 9,350x103 cell/mL at location I, 9,540x103 cell/mL at location II, and 8,300x103 cell/mL at location III. The level of diversity was low, with the dominance of Chlorella vulgaris and Chroococcus species. It is concluded that water quality and plankton composition in the waters of Parit Keladi Village still need to be managed to develop freshwater fish farming

Abstract

Pro coffee is a fermented beverage using Bacillus cereus bacterial consortium with single-cell protein. This study aims to determine the best composition of the B. cereus consortium bacteria mixture in organoleptic aspects that panelists most prefer and the effect of adding B. cereus consortium bacteria on proximate analysis and pro coffee flavor. Organoleptic testing of probiotic coffee was conducted on 20 panelists, then continued with proximate analysis of pro coffee. The composition with the best organoleptic flavor is obtained in code D, with the treatment of adding 5% bacterial consortium B. cereus for 15 days. The analysis of taste obtained has a value of 0.000 <0.05, and the study results show that the significance value is smaller than the significance level. Hence, the treatment results give the effect of adding bacterial consortium to pro-coffee. The addition of bacterial consortium B. cereus to probiotic coffee, in the form of moisture, ash, protein, fat, and carbohydrate content, is 0.000 <0.05. The analysis results show that the significance value is greater than the significance level, so the treatment results do not give the effect of adding bacterial consortium to pro coffee

Abstract

The cocoa drink is a beverage derived from processed cocoa beans. The antioxidant content of cocoa can be used as a basis for cocoa beverage development. One form of diversification of processed cocoa products is made drinks with Chlorella vulgaris fortification, which is rich in nutrients. This study aims to determine the effect of Chlorella vulgaris powder fortification on the quality characteristics of cocoa preparations and determine the best concentration for making cocoa drinks. The research method was experimental, using a factorial Completely Randomized Design (CRD) consisting of 4 different levels of formula concentration treatment, namely cocoa drink processing without Chlorella vulgaris powder fortification (KC0), 10% Chlorella vulgaris powder fortification (KC1), 15% Chlorella vulgaris powder fortification (KC2) and 20% Chlorella vulgaris powder fortification (KC3). The research parameters observed were characteristics of appearance, odor, flavor, and texture in hedonic testing, proximate composition (moisture, fat, protein, ash, carbohydrate content), solubility, antioxidant activity, and total phenolic testing. Based on the results showed that cocoa drink with 15% Chlorella vulgaris powder fortification (KC2) is the best concentration with organoleptic characteristics such as blackish brown cocoa drink, slightly fragrant chocolate odor typical of Chlorella vulgaris and cocoa, a slightly bitter taste, typical of Chlorella vulgaris and a slightly thick texture. The proximate composition is 3.18% moisture content, 11.10% fat, 7.95% protein, 3.86% ash and 73.92% carbohydrate. Meanwhile, the solubility is 67.69%, antioxidant activity is 177.92 mg/L, and phenolic content is 1.14 μg/mL. Therefore, this cocoa drink can be used as a functional drink
