Abstract

Mangroves are plants that have an important role in providing very complex and potential food components for the life of various things at there and terrestrial biota. Mangrove's high productivity is obtained from litter. This study aims to determine the rate of litter decomposition and the percentage of the leaf decomposition of Sonneratia alba mangroves in the Coastal area. This research was conducted from August to September 2021. The method used in this study was an experimental method, where mangrove leaf fall was taken and observed the decomposition rate of S.alba mangrove leaf litter in the field for 28 days, and then dried the mangrove leaf. S.alba at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau. Based on observations, it can be seen that the average temperature value ranges from 29.7 to 30.7˚C. The temperature at station I is relatively low compared to the other two stations. The measurement of the degree of acidity (pH) obtained the same results at each station, namely 7. For the measurement of salinity, the average obtained ranged from 34.3-35 ppt. The highest salinity known to be at station III is 35 ppt. In the measurement of Dissolved Oxygen (DO) the average value was obtained, which ranged from 4.60-5.89 mg/l. The decomposition process of S.alba leaf dregs which was carried out for 28 days showed that of rate of decomposition of S.alba mangrove leaf litter between stations, the highest rate of decomposition, is at station II an average of 3.92 g/day with a percentage of decomposition. 81.9% while at station III the average decomposition rate obtained was 3.35 g/day with a decomposition percentage of 75.8% and at station I is the station with the lowest rate of decomposition, which has an average of 3.25 g/day with a decomposition percentage of 67.0%.

Abstract

Community structure is a concept that studies the composition or composition of species and abundance in a community. Coastal waters are areas with a depth of less than 200 meters and there is a littoral area located between the highest tide and the lowest low tide or called the intertidal area. One of the community of organisms in this intertidal area is gastropods. This research was conducted from December 2021 to January 2022. The purpose of the study was to determine the structure of the gastropod community in the coastal waters of North Rupat District consisting of species, density, diversity index, uniformity index, dominance index, distribution pattern, and community similarity. As supporting data in this study, several environmental parameters were also measured which included water quality, sediment type and sediment organic matter content. The research method used is a survey method, where sampling using the quadrant transect method is carried out at 3 stations. Based on the results of the study found 14 species of gastropods. The species that were found in all stations were Indothais gradata. Gastropod density is 15.800 ind/ha. Diversity index value (H') 1.85, uniformity index (E) 0.70, dominance index (C) 0.24, distribution pattern (Id) 3.24 is clustered, species similarity index (Ss) between stations Tanjung Medang and Teluk Rhu 83% of species are almost the same and between stations Tanjung Medang and Tanjung Punak 15% and between stations Teluk Rhu and Tanjung Punak 17% are not the same. Water quality parameters as follows: temperature 27-28oC; salinity 30-31 ppt; pH 6-7. Sediment organic matter 0.50-2.28%, sand sediment type.

Abstract

Pasumpahan Island is one of the islands located in West Sumatra Province which has various activities of daily life, especially in the intertidal zone; it is suspected that it can interfere with the existence of aquatic organisms one of which is gastropods. Studying the structure of gastropod communities in the intertidal zone is an interesting natural laboratory to study. This research was conducted from December 2021 to January 2022 on Pasumpahan Island Padang City West Sumatra Province. The purpose of this study was to determine the structure of the gastropod community which includes species, abundance, diversity, uniformity, dominance, and distribution pattern of gastropods. As supporting data in this study, several environmental parameters were also measured which included water quality, sediment type, and sediment organic matter content. The research method used is a survey method, where sampling using the quadrat transect method is carried out at 3 stations. Based on the results of the study found 13 species of gastropods. The most common species found at all stations was Pythia scarabaeus, where the gastropod abundance values obtained between stations ranged from 2,78 to 5,00 ind/m2. The value of the species diversity index ranged from 1,50 to 2,02, which was moderate, the uniformity index value ranged from 0,77 to 0,88, which was high uniformity, and the dominance index value ranged from 0,16 to 0,29, meaning that there were no species found dominates and the value of the distribution pattern ranges from 1,31 to 2,47 with a clustered distribution pattern.

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

Razor clam (Solen lamarckii) is a type of pelecypoda that has high economic value on the Api api village waters, Bengkalis Regency. This research aims to study the population structure and reproduction of razor clam. The study was carried out over 2 month period from September to October 2019 at Api api village waters, Bengkalis Regency. Razor clam samples were collected by using a 1 x 1 m2 frame that laid along transect. There were 5 plots and 5 subplots along the transect as replications. The result showed, the population density of razor clams is 3.12 species/m2 in September and 2.88 species/m2 in October 2019. The distribution pattern of razor clams was uniform. While, the most common size of razor clam is the medium size category (40-60 mm) both in September and in October 2019. The average value of gonado somatic index (GSI) was 2.28-8.60%. Histological analysis indicated that maturity gonad stage of razor clam was commonly found in September is maturity gonad stage I (60%), while in October is stage III (40%) and stage IV(30%).

Abstract

Jalan di beberapa desa memiliki permasalahan besar yaitu kerusakan yang terjadi di beberapa titik jalan dan tidak adanya rambu-rambu jalan. Masalah ini juga terjadi di Desa Gerbang Sari, Kecamatan Tapung Hilir, Kampar. Untuk mengatasi permasalahan tersebut dan mempermudah akses jalan ke dusun-dusun yang ada di Desa Gerbang Sari, Mahasiswa KUKERTA telah melakukan kegiatan pengadaan rambu-rambu jalan bagi dusun-dusun setempat guna mempermudah dan melengkapi sarana prasarana penunjuk arah ke dusun-dusun. Kegiatan dilaksanakan dengan 4 (empat) tahapan kegiatan, yakni: 1. terlebih dahulu melakukan survei lapangan di lokasi yang nantinya akan menjadi titik pemasangan rambu-rambu jalan desa, 2. menyiapkan alat dan bahan untuk membuat rambu-rambu jalan desa, 3. dilakukan proses pengecatan dan 4. pemasangan rambu-rambu jalan desa oleh mahasiswa dibantu oleh pemuda dan masyarakat sekitar. Terdapat 11 rambu dengan nama jalur dan 1 denah lokasi. Program tersebut mendapat dukungan dan pendampingan dari pemuda dan masyarakat Desa Gerbang Sari sehingga dapat terlaksana dengan baik. Dalam proses kegiatan mulai dari persiapan hingga pelaksanaan program, tidak ditemukan kendala yang berarti. Selain itu, berdasarkan 3 indikator survei tingkat kepuasan masyarakat dan pengunjung desa terhadap pengadaan dan pemasangan rambu-rambu jalan menunjukkan bahwa masyarakat puas dengan program tersebut.
