Abstract

The mangrove forest area is important for benthic epifauna because it is a habitat for benthic epifauna. This research was conducted in September 2020 in the mangrove forest rehabilitation area of ??Kedaburapat Village, Kepulauan Meranti. In this study, it was divided into 2 areas, namely the mangrove planting period 2018 and the planting period 2019. The result of this study found 18 species from 2 classes, Gastropods and Malacostraca. Gastropod class namely Littoraria melanostoma, Nerita balteata and Sphaerassiminea miniata; and Malacostraca classes namely Macrophthalmus convexus, Clibanarius longitarsus and Clibanarius ambonensis. Macrozoobenthic abundance values ??ranged from 50.33 to 46.63 ind/m2, the diversity index value (H ') was between 1.23-2.27, the dominance index value was 0.30-0.65, the uniformity index (E) ranged from 0.32-0.67 and the distribution ranges from 0.94-1.61. Water quality parameters measured include temperature, salinity, pH, organic matter, TSS and substrates that affect the presence of benthic epifauna

Abstract

This research was conducted in November 2020 at Nirwana Beach, Teluk Bayur, Padang City, West Sumatra Province. The organic carbon concentration in the sediments at Nirwana Beach ranges from 1.0320 – 3.03550%, the nitrate content ranges from 0.8599– 0.9577 mg/L, the phosphate 1.8231– 2.7616 mg/L. The C:N:P ratio of sediment is 18.75:1:2.25. The type of sediment found in this study is gravel-sand and seagrass found in the research location was  Thalassia hemprichii with a density of 105 - 312 stands/m2. The correlation between the concentration of organic carbon, nitrate, and phosphate on the density of seagrass species is positive

Abstract

This research was conducted in August 2021 in Apar Village, Pariaman City, West Sumatra Province. This study aims to determine the diversity and distribution pattern of gastropods in the mangrove ecosystem of Apar Village, Pariaman City. The method used in this research is a survey method. A sampling of gastropods was carried out by purposive sampling method and sediment sampling was carried out using a 10 cm paralon pipe with a depth of 10 cm. The results showed that the diversity of gastropods in the waters of Apar Village was included in the low category. The highest density of gastropods was Faunus ater which was found at each station, while the lowest density was Ellobium aurisjudae and Latirolagena smaragdulus which were only found on the coast of Apar Village, Pariaman City. The overall distribution pattern of gastropods at each station was evenly distributed and gastropods in the study area were in the high category. Based on the analysis of sediment organic matter in Apar Village, the highest average value was 29.43% and the lowest was 6.51%. The results of the analysis of the sediment fraction at each station of the sediment type were muddy sand

Abstract

Mangrove ecosystems are unique ecosystems found along the coast or river mouths that are still influenced by tides. Association is a process of interaction between organisms and their environment which is not simple but a complex process. One of the biota associated with mangroves is macrozoobenthos. This research was conducted in August 2021. The purpose of the study was to determine environmental conditions, mangrove species and density, macrozoobenthic species and density, and the relationship between macrozoobenthic density and mangrove forest density in Dumai waters. Based on the results of the study, the types of macrozoobenthos were found from the gastropod and bivalves classes. The type that is found in all stations is Nerita lineata. The highest density is at station III, which is 19.11 ind/m2. Mangroves in Dumai waters are classified as dense with the dominant species being Rhizophora apiculata and Xylocarpus granatum. The relationship between the density of macrozoobenthos and the density of mangroves belongs to the medium category

Abstract

This research was conducted in January 2021 in the Mangrove Area of Gogok Village, Meranti Islands Regency, Riau Province with the aim of knowing the abundance and distribution pattern of Thalassina anomala in the area. The method used is a survey method. Sampling used the line transect method. Sampling was carried out by drawing three transect lines, starting from the lowest low tide line along 45 m inland at each station. carried out on square plots measuring 5x5m. The parameters measured were temperature with an average value of 27.7oC, salinity with an average value of 26.7 ppt, and pH with an average value of 6,8. The results showed that the Thalassina anomala found in the mangrove area of Gogok Village, Meranti Islands Regency, Riau Province was 6.6 ind/25m2. Meanwhile, the distribution pattern of the Thalassina anomala in the area is completely random. The moths live in nests with sediments with low bulk density values, namely on fine-textured soils and granular structures with bulk density values between 0.1 - 0.9 g/cm3. Based on the analysis of organic matter content carried out in the mangrove area of Gogok Village, Meranti Islands Regency, Riau Province, it can be seen that the organic matter content is high between 42,1833 - 58,1833%

Abstract

Spirulina platensis is a microalga that has high economic value. The growth of S.platensis is influenced by environmental conditions and nutrients. The objectives of this study are to determine the best concentration of coconut water for media of S.platensis growth. The study was conducted at the Natural Feed Laboratory of the Brackish Water Aquaculture Center (BPBAP) Ujung Batee Aceh. This research is an experimental study using a completely randomized design (CRD) consisting of 3 levels of treatment and control using coconut water of the media with concentrations of 3%, 5%, and 7% with 3 replications. The highest cell density level of S.platensis reached 83.102 cells/ml in treatment A (3%), in treatment B (5%) 73.975 cells/ml, the density in the control treatment reached 70.850 cells/ml, and in treatment, C (7%) cell density only reached 54.658 cells/ml. The results of the ANOVA test on day 2, day 3, day 5, and day 6 showed that the addition of coconut water with different concentrations had a significant effect (p<0.05) on the growth of S.platensis
