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

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

Pasta feed is an alternative replacement feed naturally occurring in cultivating Asian redtail catfish (Hemibagrus nemurus) larvae. However, pasta feed is not yet able to completely replace the Tubifex sp, and enrichment feed pasta with oils from mesenteric waste catfish is expected to improve the performance of pasta feed. This research aimed to determine the effect of enriching fermented pasta feed with waste oil from the mesenteric parts of catfish on the growth and survival of Asian redtail catfish larvae. This research used an experimental method with the design used, a Completely Randomized Design (CRD), one factor, and five treatments with three replications. This research was carried out from March to April 2024 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty, Universitas Riau. The research results show the influence of enrichment of fermented pasta feed with pangasius mesenteric fish oil on the growth and survival of Asian redtail catfish larvae. Given larvae feed fermented paste + fish oil from pangasius mesenteric waste 12 % produce growth and survival highest with an absolute weight of 1.63 g, absolute length of 5.33 cm, specific growth rate of 14.73%/day, survival of 84.44%, type A cannibalism index of 13.77%, and normal mortality of 1.77%.

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

Abstract

     This study aims to investigate the interannual variability of Sea Level Anomaly (SLA) along the western coast of Sumatra waters, focusing on the influences of the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) in modulating SLA patterns. Using 31 years (1993-2023) of a gridded dataset from Copernicus Marine Service (CMS) and climate indices as the reference, the interplay between SLA and climate modes (ENSO and IOD) was determined through lag/lead correlation and spatial distribution analysis. The analysis shows a clear inversive relationship between ENSO and SLA, with a one-month delayed negative correlation (r= -0.41), indicating that SLA increases during the La Niña phase due to shifting in atmospheric and oceanic conditions. Similarly, SLA exhibits a negative correlation with DMI (r= -0.46) without any lag, suggesting a rapid response of SLA to IOD. Spatial analysis further demonstrates that ENSO and IOD most strongly influence SLA along Sumatra’s coast within the first 1–3 months. These findings reveal that ENSO and IOD modulate SLA variability with distinct spatiotemporal characteristics, providing crucial insights for understanding coastal dynamics and enhancing mitigation strategy for sea level-related disasters in the western coastal region of Sumatra
