Abstract

The Dumai City area is one of the regions currently designated as an industrial zone, a transportation route, and a busy international port. This situation puts significant pressure on the marine waters of Dumai City due to the waste produced. The primary source of marine pollution comes from oil spills, whether from ship operations, offshore drilling, or ship accidents. Pollution from oil spills in the ocean is a significant source of marine contamination that has consistently been a focus of public attention. This study aims to analyze the total oil content, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), and Total Organic Matter (TOM), as well as the effect of total oil content on DO, BOD, and TOM. The survey method used in this research involves collecting data from DO, BOD, TOM, and oil content measurements. The total oil content in Dumai City waters ranges from 0.14485 – 0.30214 ppm. The total oil content below the threshold still supports aquatic biota and does not damage the ecosystem. The DO content in Dumai waters ranges from 3.6 to 6.8 mg/L, and some measurements are below the threshold required to support marine biota. The BOD content of Dumai waters ranges from 10 to 11.3 mg/L, meaning that biological activity is still within optimal limits. The TOM content ranges from 17.38 – 35.22 mg/L, which does not support the life of aquatic biota, and there is potential for organic material pollution

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 process of processing smoked fish that does not pay attention to sanitation and hygiene standards, as well as open storage next to the road body, causes dust, germs, and bacteria to contaminate the quality of processed smoked flying fish in the Somba culinary tourism center. This study aims to evaluate the microbiological quality of smoked flying fish based on Total Plate Count (ALT) and water content to assess its compliance with food safety standards. This study used a combination method of sequential exploratory model, which is a combination research method that combines qualitative and quantitative research methods sequentially. Data collection was carried out by purposive sampling, and the parameters for this sampling were based on the 10 stalls with the most production and customers. The results showed that out of 10 samples, there were only four samples that met the SNI requirements of a maximum of 1.0×105 colonies/g, including samples S2 (2.74×104), S5 (2.53×104), S9 (2.33×104) and S10 (2.38×104). In contrast, the results of the water content test show that out of 10 samples, there are only three smoked flying fish samples that have a water content value that matches the maximum limit of smoked fish based on SNI, which is a maximum of 60% including samples S2, S5, and S9

Abstract

Nugget is one of the processed products from fish meat, whether fish is economically important or not. Nuggets are very popular with various circles of society because of their savory and delicious taste. Nuggets are made from fish meat and are believed to have a composition of nutritional value that is needed by the human body. This study aims to see the effect of adding egg whites to the organoleptic test of the nuggets produced and to see the level of preference of the panelists on the refined anchovy nuggets produced. The usefulness of this research is the diversification of processed fishery products that can be consumed by the community and has important economic value and it is hoped that the research results will be useful for the community about new sources of information regarding egg white substitution can produce anchovy nuggets (Stolephorus, sp) with good organoleptic tests. The method used is an experimental method. In this study, there were 2 treatments, namely there were two treatments A (egg white concentration) namely A1 = 50 g egg white, A2 = 100 g egg white A3 = 150 g egg white and treatment B ( heating temperature) namely B1 = 40 0C 15 minutes, B2 = 65 0C 20 minutes, B3 = 95 0C 30 minutes. In this study, subjective observations were made including color, texture, folding, and taste tests carried out by 15 panelists. The results showed that the administration of egg whites and heating at a temperature of 650C produced a good gel nugget color, due to a change in the color pigment. Egg whites can inhibit the softening of the gel because when heated, the value of the texture of the nugget becomes better. Meanwhile, the folding test value obtained was very high, namely 3.754, due to the fact that egg white inhibits serine proteinase so that the gelling strength increases.

Abstract

The macrozoobenthic community structure can be used as a bioindicator to determine water pollution. The macrozoobenthic community structure consists of species, abundance, diversity index (H '), dominance index (C) and species uniformity index (E). This research was conducted in July 2020 in the waters of the North Coast of Bengkalis Island. Water parameters measured include temperature, salinity and pH. In this study, it was divided into 3 stations, namely in Selat Baru Village (station 1), Jangkang Village (station 2) and Teluk Pambang Village (station 3). The results found that as many as 34 species from 4 classes of macrozoobenthos, namely Gastropods, Malacostraca, Bivalvia, and Merostomata. Gastropod class macrozoobenthos such as Volema pyrum, Littoraria scabra, Nassarius vibra, Drupella margariticola, Pirenella cingulata, and Nerita costata; from the Malacostraca class such as Uca dussumieri, Ocypode kuhlii, Clibanarius longitarsus, and Litopenaeus cetiferus; from the Bivalvia class such as Glauconome virens, Polymesoda expansa and Dinocardium robustum and from the Merostomata class such as Carcinoscorpius ratundicauda. The macrozoobenthic abundance values ​​from the three stations ranged from 0.01 to 1.29 Ind/m2, the diversity index value (H') ranged from 2.5589 to 2.8516, the dominance index value ranged from 0.2503 - 0.3312 and the uniformity index (E ) ranges from 0.6397 to 0.6838. Water quality parameters are as follows: temperature is 29-31°C, salinity ranges from 23-28 ppt, and pH ranges from 7.5-7.9. Sediment organic matter ranged from 6.88 to 11.26% and TSS ranged from 474-542 mg/L with the dominant sediment type at the three stations, namely sandy mud. This shows that the waters north of Bengkalis Island are classified as being polluted.

Abstract

Kasiak Island is one of the islands located in the waters of Pariaman, West Sumatra, and located right in front of Pariaman City. Around the sea, the island is surrounded by coral reefs and is a protected area. In the aquatic area of Kasiak Island has never been conducted research on the relationship of coral reef cover to the coral Pomacentridae and phytoplankton. Therefore, it is necessary to conduct research on this matter in the waters of Kasiak Island, West Sumatra Province. Data collection of coral reef cover is done by the LIT (Line Intercept transect) method with a transect length of 50 meters at a depth of 5 meters using scuba equipment. Coral fish observation is done by UVC (Underwater Visual Census) method with a transect length of 50 meters and an observation area of 2.5 meters left and right at a depth of 5 meters. Phytoplankton sampling is conducted during the day at 11.00 to 15.00 WIB at five points of the station with a depth of 5 meters using Vandorn water sampler volume 2 L with a total take of 100 L, then filtered using Plankton net no 25 and inserted into a sample bottle of 125 ml, then preserved using Lugol 4% as much as 4-6 drops, after which analyzed in the laboratory. Based on the results there is a very strong relationship between coral cover to the abundance of coral fish, where coral cover contributes to the abundance of coral fish by 93.87%, which means that the higher the percentage of coral cover the more species and abundance of coral fish are found. Then the a strong relationship between coral reef cover and phytoplankton abundance, where coral reef cover contributes to the abundance of phytoplankton by 56.37%, which means an increase in the percentage of coral reef cover along with the increasing abundance of phytoplankton.
