Abstract

The purpose of this study was to determine the effect of rainfall and wind on fish catches for fishermen at Bungus Ocean Port, West Sumatra. Rainfall and wind data were obtained from BMKG Teluk Bayur, Padang, while fish catch data were obtained from PPS Bungus staff, West Sumatra. The methods used in this research activity are the survey method and quantitative analysis. The results of this study showed that rainfall in the study area ranged from 0.01-15.4 mm, the average wind speed ranging from 1.0-1.6 m/s for the catch ranging from 334.983-560.145 kg. The results of the analysis between rainfall and wind on fish catches showed the correlation is not too intense because, based on the results of interviews, fishermen make voyage trips or fishing trips where fishing trips are carried out for more than one day, sometimes even more than one month, so additional data is needed for future research in the form of fishing trip data and data of ships departing per trip

Abstract

Muara Air Haji Village is a coastal area with various anthropogenic activities that can disrupt the aquatic ecology, especially in the intertidal zone. Biological indicators such as macrozoobenthos are needed to provide a correct and sustainable picture of water quality. This research uses a survey method to determine macrozoobenthos' type, abundance, diversity, uniformity, dominance, and distribution pattern in the intertidal zone. Sampling was carried out using three stations, and each station consisted of three transects and three subzones comprised of the upper, middle, and lower intertidal zones using a quadrant plot measuring 1 x 1 m. The results of this research found three classes of macrozoobenthos with five species. Abundance values ​​at each station ranged from 0.89–4.56 ind/m2, while abundance in the intertidal subzone ranged from 1.11–3.56 ind/m2. The diversity index (H') at stations I and III is 1.93 and 1.17, which means it is included in the medium diversity category, while the diversity index (H') at station II is 0.84, which means it is included in the low category, moderate distribution of individuals or non-uniform number of individuals, moderate ecological pressure and moderately polluted water stability. The uniformity index value ranges from 0.65–0.99, which means the uniformity category is balanced. At station II, macrozoobenton dominates with an index value of 0.62, while stations I and III have no dominant species with index values ​​of 0.30 and 0.45. The distribution pattern (Id) of macrozoobenthos is clustered with a value of 3.45–4.18.

Abstract

Bacillus cereus SN7 is a bacterium with potential applications in producing Single-Cell Protein (SCP). SCP can be an alternative to protein derived from traditional sources like agriculture, fisheries, and animal husbandry. Encapsulation is a process used to stabilize cells, aiming to potentially enhance probiotics' viability and stability throughout production, storage, and handling. This study aims to make capsules from B. cereus SN7 single-cell protein to protect them from contaminants. This study used a survey method, which carried out in-situ processing of bacteria, as well as conducting experiments on the formation of bacterial encapsulation, testing the effectiveness of encapsulation, and observing the viability of B. cereus SN7 bacteria by counting the number of colonies. B. cereus produced biomass with a total dry weight of 1.3708 g/mL. The alginate encapsulation experiments can be formed into capsule beads that protect bacteria. The best encapsulation process is an alginate-based coating, which is indicated by the ability of the alginate to withstand temperature, pH, and salinity.

Abstract

Bivalvia is a class of the Mollusca phylum. Bivalvia is also known as Pelecypoda and Lamellibrankhiata. Bivalvia occupies an area of the intertidal zone, one of which is in the intertidal zone of Pasumpahan Island. But information about bivalves in the area does not exist. To know/understand information about the density and distribution pattern of bivalves on Pasumpahan Island, this research was conducted in January 2022. The sampling area was in the intertidal zone of Pasumpahan Island. Sampling was carried out at three stations, each station was divided into three transects. Bivalve sampling was carried out using a 1 x 1mm sieve. The movement of bivalves to the gravel substrate is very fast to avoid splashing waves. Bivalves samples were then identified. The density of bivalves in the intertidal zone of Pasumpahan Island ranged from 1.78-3.56 Ind/m2. Station 2 has a higher density of bivalves, namely 3.56 Ind/m2, the calculation of bivalves in the intertidal zone of Pasumpahan Island obtained bivalves distribution pattern data in groups
