Abstract

This research was conducted in February until March 2017 at Pandan Island island pandan area tourist Park Pieh Island. The purpose of this study was to investigate the characteristics of the nesting habitat of the hawksbill turtle (Chelonia mydas). The method used in this research is the survey method, with measuring directly on the habitat of hawksbill turtle covering the slope of the beach, texture of sediments, within the nest of tides, the temperature of the nest, fecundity, and the type of vegetation and predators in the nesting habitat. The results showed that the nesting habitat characteristics vary between nest with each other. Nesting beach ramps ranged 2,75-4,60º with medium sand sediment texture to coarse sand. Temperatures nest ranging between 27-31ºC. The dominant vegetation in the area is a nesting plant pandan laut (Pandanus tectorius) whereas the dominant predator was biawak (Varanus salvator).

Abstract

Sungai Kayu Ara Village, Siak Regency, Riau Province is a coastal village. The main livelihoods of the people in this village are farming, fishermen and breeders. Pellets and concentrate feed have been used by the community as fish and livestock feed. But the high price of this feed makes this business less profitable. Azolla microphylla as fish feed and livestock has been introduced in Indonesia. This community service activity aims to train coastal communities of A. microphylla cultivation techniques which will later be used as fish feed and other livestock. This activity was carried out with the following stages; 1) Location survey, group formation and coordination. 2) Get off to the field and prepare sites for training. 3) Training of growing substrate fermentation techniques A. microphylla. 3) Training to prepare A. microphylla growing containers. 4) Cultivation training of A. microphylla. 5) Harvesting and giving A. microphylla to livestock. 6) Monitoring and evaluating the results of the trainings. A group of cultivators of A. microphylla has been formed and training has also been carried out with the students of the 2018 UNRI LPPM KKN participants in this village. This group named "SUKARELA" stands for the Sungai Kayu Ara Pemelihara Azolla with 30 members. Initial monitoring results in the second, third and fourth weeks after training showed that these macrophytes can grow well. Some members have enlarged the maintenance container in the form of maintenance tanks.

Abstract

This research aims to determine the description of the presence of macrozoobenthos which is thought to have been affected by coastal stockpiling which has recently been carried out around the Mandeh Tourism Area. This research was conducted in January - March 2022, the method used in this research is purposive sampling with sampling using the transect method. The results of this study indicate that the water quality of Nagari Mandeh is sufficient to support the life of macrozoobenthos, the macrozoobenthos found consist of 10 families, namely Arciidae, Cardiidae, Cerithiidae, Fasciolariidae, Neritidae, Potamididae, Psammobiidae, Tellinidae, Turbinidae, and Strombidae. The type of sediment in the waters of Nagari Mandeh consists of gravel sand, colloid, sandy silt, silty sand, and sandy gravel. The content of total organic matter (BOT) from sediments in the waters of Nagari Mandeh was found to be in the range of 8.08% - 15.25% (medium). Coastal reclamation activities do not have an impact on the presence and diversity of macrozoobenthos but have an impact on the types of individuals living around the reclamation area

Abstract

Intensive observation of gastropods, every March from the year 2008 to the year 2012, was carried out to document some indicators of gastropod extinction. The purposive sampling technic was used in this work. The physicochemical parameters of its habitat were also monitored during every sampling done.  It was found that the intertidal substrate consist of sand, while the habitat parameters were more than 5,6 mg/L dissolved oxygen, pH around 7,0-7,2, salinity 30,2-32,2 ppt, temperature 28,6-29,60C, the visibility 100%.  The number of species, the number of found gastropods, the abundance, and the maximum shell size of found gastropods showed decreasing from year to year, while routine collecting by the visitor and the marine organism shell collector, and the disturbance by the fisherman activities occurred. This indication showed a tendency for gastropods extinction

Abstract

Padang City is one of the cities with a long coastline. The Padang City government has made many reforms to manage the beach area as a tourist attraction. This research aimed to determine the comparison of macrozoobenthos community structure, including species composition, species abundance, relative abundance, diversity index, similarity index, dominance index, and distribution patterns in the reclaimed and natural beaches of Padang City, West Sumatra Province. The method used was purposive sampling with sample collection using the transect method. The results of this study indicate that the water quality in Padang City, West Sumatra, is sufficiently good to support macrozoobenthos life. The highest species abundance of macrozoobenthos was found at the Reclamation Beach Station. The macrozoobenthos species found belong to 2 classes: Gastropoda and Crustacea. The Gastropoda class consists of 4 species: Babylonia spirata, Pila ampullacea, Pila occidentalis, and Nerita fulgurans, while from the Crustacea class, three species were found: Ashtoret lunaris, Hemigrapsus takanoi, and Emerita sp. Meanwhile, the lowest abundance was found at the Natural Beach Station, where the species belonging to the Crustacea class, specifically H.takanoi, was found. The species diversity of macrozoobenthos at the Natural Beach Station is considered low but moderate at the Reclamation Beach Station. Similarity at the Natural Beach Station is low, while at the Reclamation Beach Station, it is high. Additionally, there is a dominant species at the Natural Beach Station, whereas no dominant species were found at the Reclamation Beach Station. The distribution pattern of macrozoobenthos in the coastal waters of Padang City is categorized as clustered distribution

Abstract

This study was conducted in September 2021, around the coastal of Concong luar village Indragiri Hilir Regency with the aim to find out the abundance, distribution, and morphometrics of blood shell (Anadara granosa). The method used survey methods, in which blood shell sampling and aquatic substrates, as well as measurements of environmental parameters, were conducted in the field and in the laboratory. Determination of sampling location by purposive sampling is based on the character of the environment in the location of the research. Based on the results of research that has been obtained an abundance value at the station 1 = 4,8 Ind/m2, station 2 = 8,7 Ind/m2, and station 3 = 3 Ind/m2. The pattern of blood shell levy in the waters of Concong Luar Village stations 1 and 2 is clustered, while station 3 is evenly distributed. Furthermore, the results of measurement of the width of the highest blood shells are 16 - 30 mm in 70 individuals, followed by size >31 mm in 43 individuals, the lowest measurement result is <15 mm in 27 individuals and the highest measurement of the length of the blood shells 16 – 30 mm of 77 ind, followed by a size >31 mm of 42 ind, and the lowest measurement result is <15 mm of 29 ind
