Abstract

Paloh, one of West Kalimantan's conservation areas, has a high biodiversity of marine resources, including seaweed. Seaweed has an important ecological role, such as increasing primary productivity, providing dissolved oxygen, as a food source, and as a habitat for several aquatic organisms. In addition, seaweed contains various bioactive compounds that have the potential to be used in various industrial fields. This research aimed to identify the variety of seaweed in the waters of Pantai Tanjung Api, Paloh District, Sambas Regency, West Kalimantan. Based on the abundance of seaweed, the sampling site was chosen. A quadratic transect measuring 10x10 m2 was used for the collection. Four seaweed genera were discovered, including Acetabularia, Ulva, Padina, and Sargassum. Ulvophyceae and Phaeophyceae had the same percentage contribution. The species abundance varied between 1.04-26.75 ind/m2, where Padina had the highest value. Paloh has a low level of seaweed diversity, high uniformity, and a low dominance index

Abstract

The purpose of this study was to determine the type, abundance, and community structure of epizoic diatoms attached to the shells of the snails Cerithidea obtusa and Nerita articulata in the mangrove ecosystem of Dumai City, Riau Province. This research was conducted in January 2022. A sampling of snail shells took place in the mangrove ecosystem of the city of Dumai, Riau Province, and was identified at the Marine Chemistry Laboratory, Department of Marine Science, Faculty of Fisheries and Marine, Universitas Riau. Based on the research that has been done, the results show that there are 13 genera of epizoic diatoms consisting of 5 genera centrales and 8 genera of pennales order. The highest abundance of epizoic diatoms in C.obtusa snail shells was at station II with a value of 29,687 ind/cm2. While the highest abundance of epizoic diatoms in N.articulata shells was at station I. Based on the average values of diversity index (H'), dominance index (D), and uniformity index (E) it can be concluded that epizoic diatoms in C.obtusa and N.articulata have a moderate biota community balance value, moderate polluted water quality, no dominant species and unbalanced organism uniformity and food competition occurs

Abstract

Research on the population structure of bamboo shells (Solen lamarckii) in the intertidal zone of Sri Tanjung Village, Rupat District, Bengkalis Regency was carried out in October 2021-March 2022. This study aimed to determine the population structure of bamboo shells and the relationship between the size of bamboo shells and the depth of bamboo shells in the sediment. The intertidal zone is divided into 5 subzones. Each subzone is placed in 3 plots measuring 1 x 1 m2 along the transect line as a replication by drawing a straight line from the boundary of the highest tide area to the lowest low tide area. The results showed that the average population density of bamboo shells was 1.20 ind/m2 or 12,000 ind/ha with the lowest density located in the highest tide area and the highest density located in the lowest low tide area. The distribution pattern of bamboo shells is uniform. The size of the most common bamboo shells found is 5.14-5.70 cm. The relationship between the size of the bamboo shells and the depth of the bamboo shells in the sediment is very weak

Abstract

The purpose of this study is to know the value of an economic benefit of the total mangrove forest located in the village of Pulau Cawan Indragiri Hilir regency, namely using the concept of valuation economic in calculating the benefits of mangrove existence that has the potential of existing natural resources. This research was conducted in August 2020, The observations made in the field use observations and direct interviews with the local government and the community around the village of Pulau Cawan. The results of the research obtained showed the ecosystem of the mangrove forest area of the village of Pulau Cawan which has an area of ±3,401.66 ha, and there is a value of existing benefits of IDR 21.200.000 ha/year. The factors that will affect the willingness to pay (WTP) of the community around mangrove forests in the form of the respondent's income level, the respondent's education level, the respondent's gender, the respondent's age, and the respondent's family dependents. The benefit value of the existence of The Village of Pulau Cawan can be used as a basis for decision-making by the local government and the surrounding community in the management of policies and utilization of mangrove forests in maintaining and preserving mangrove forest ecosystems for the sustainability of the future with the results obtained in knowing the existence of the value function of a mangrove ecosystem, it can result in the formulation of the mangrove forest conservation reserve area of Pulau Cawan village, namely the implementation and development of the “Ecu-Edu Wisata Mangrove” (EEWM) concept plan.

Abstract

This research was carried out in December 2021-January 2022 in Dumai City District, Riau Province. The purpose of this study is to determine the rate of sea level rise based on analysis of tide data from 2001-2021 and to predict inundation areas in the next 20 years. This research method is a descriptive survey using remote sensing as an additional tool to show the results. Acquisition needs are in the form of primary data (land use and tide data) and secondary (slope data, elevation, land use, and tide data). These parameters are processed and analysed to describe the extent of the inundation by displaying a map of the City of Dumai. The results showed that the waters of Dumai City have a Formzhal number of 0.5, which means that the water area is classified as a mixed tide, semi-diurnal prevalence, with a sea level rise of 2.003 cm/year. Then, the numbers used to predict the height of sea level rise in the next 20 years are 0.973 m each. Furthermore, sea level height was analysed to obtain the inundation area for the next 20 years, it turns out that the inundation area each year is 11.89 ha

Abstract

This study aimed to examine the antioxidant activity of bioactive peptides on protein hydrolyzes of Bombay duck (Harpodon nehereus)from hydrolysis using papain enzyme. This research used an experimental method, with a wholly randomized non-factorial design consisting of enzyme concentration factors (1,5, 2, and 2,5%). Parameters tested include chemical composition tests of Bombay duck's meat, flour, and protein hydrolyze, identification of short peptide chains, and antioxidant activity. The results showed that Bombay duck protein hydrolyzes with papain enzyme concentration. There was a significant difference, where the enzyme concentration of 2,5% has the highest degree of hydrolysis of 69,18%. The chemical composition of meat was water 73.15% (ww), protein 81.97% (dw), ash 5.57% (dw), and fat 4,49% (dw). The chemical composition of flour Bombay duck was water 8.32% (ww), protein 79.88% (dw), ash 4,89% (dw), and fat 3,41% (dw). The best treatment of Bombay duck protein hydrolyze at an enzyme concentration of 2.5% resulted in a chemical composition of water 6.73% (ww), protein 80,56 % (dw), ash 5,53 % (dw) and fat 3,11 % (dw). The results of the identification of peptide compounds were L-Pro-L-Ile, L-Leu-L-pro, L-Arg-D-Pro, Leu-Ala-Arg-Leu, and L-Thr-L-pro-L-lys. Furthermore, DPPH free radicals (IC50) scavenging power was 5.19%.

Abstract

This research was conducted in October - November 2021 in Rawa Mekar Jaya Village, Sungai Apit District, Riau Province. The study area includes the mangrove forest of Rawa Mekar Jaya Village and Rawa Mekar Jaya River. Managing mangrove forests sustainably requires an integrated and sustainable management strategy; therefore an evaluation of sustainability status is carried out through 27 indicators grouped into four dimensions, namely ecology, economy, socio-culture, and institutional law. Indicators were obtained from previous research, literature studies, and field observations. Sustainability index assessment categories (1-100) can show the status of sustainability in mangrove forest ecosystem management in a multi-dimensional. Overall, the sustainability status of the multidimensional mangrove forest ecosystem of Kampung Rawa Mekar Jaya is classified as less sustainable with an average of 45.62. Socio-cultural (14.92) and economic (26.34) dimensions need improvement but the ecological and legal dimensions of the institution must be maintained
