Abstract

Mangrove ecosystem is a coastal wetland has biodiversities such as flora, fauna, and microorganisms. Microorganisms are an importants component in the mangrove ecosystem and have many roles, including source the nutrition, decomposer, and a source of biotechnology products. Cellulolytic bacteria are a group of cellulase-producing bacteria capable of breaking down cellulose into glucose monomers. This study aims to screen and determine the diversity of cellulolytic bacteria from the mangrove ecosystem. The research method has been experimental by exploring the cellulolytic bacteria in soil and sediment from the mangrove ecosystem. Three sampling locations were selected such as the litter soil, soil in the root, and soil in the tidal area. The screened of potential bacteria-producing cellulase was obtained by bacteria growth on Carboxy Methyl Cellulose (CMC) agar medium. The isolates were cultured for 48 hours at 37°C. Then, the bacteria that produced the cellulolytic activity were characterized by morphological and physiological characteristics. The results were adjusted according to Bergey's Manual of Determinative Bacteriology. The determination showed that six isolates had the same characteristics as Bacillus, Cellulomonas, Lactobacillus, and Micrococcus. The cellulolytic activity index showed that three isolates were sequentially MS06 (9,73), MS03 (6,30), and MS08 (5,41).

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 analyzed to obtain the inundation area for the next 20 years, it turns out that the inundation area each year is 11.89 ha.

Abstract

Indigofera leaf meal can be used as an alternative raw material and has high potential as a source of vegetable protein for Hoven’s carp fry to reduce the use of imported raw materials. The purpose of this study was to examine the effect of using indigofera leaf meal with different combinations of feed as feed raw materials on growth performance and survival of Hoven’s carp (Leptobarbus hoevenii) fry. This study was carried out from July to August 2021 at the freshwater aquaculture center (BPBAT) Sungai Gelam Jambi. This study method used a completely randomized design (CRD) with 3 treatments and 3 replications, i.e: control (commercial feed 100%), treatment 1 (commercial feed 50%+ indigofera leaf meal 50%), and treatment 2 (indigofera leaf meal 100%). The data obtained were analyzed by Anova and further tested by Duncan's test. Based on the analysis of variance, the use of Indigofera zollingeriana leaf meal had a significant effect (P<0.05) on absolute weight growth, absolute length, specific growth rate, and feed conversion ratio, while survival rates were not significantly different (P >0.05). The results showed that the increasing proportion of the use of indigofera leaf meal experienced a decrease in the growth performance of Hoven’s carp fry.

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

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.
