Abstract

These marine natural resources include various types of fish, molluscs, and crustaceans. Maluku is a waters rich in benthic organisms, the coastal environment of Seri village can be said to be productive which shows various types of resources that can be utilized continuously in the presence of various types of marine organisms or marine biota such as Nerita. This research is a form of scientific contribution to learning marine biology. This research is a descriptive type of research, to describe or describe information about the density of Neritidae in the coastal waters of Seri Village which is made in the form of tables and figures. The results of the calculation of the density of Neritidae in the coastal waters of Desa Seri which were carried out as a whole from 3 transects found 7 species, 1 family, 1 genus and 207 individuals in the phylum Mollusca. By calculating the density on the coast of Seri Village, the values ​​for each species are as follows: Nerita squamulata is 0.001833, Nerita chamaeleon is 0.002167, Nerita maxima is 0.002167, Nerita polita is 0.026333, Nerita albicilla is 0, 0015, Nerita planospira was 0.000333 and Nerita patula was 0.000167 with a total absolute density of 0.0345. according to the density category according to Cox (1967) which explains that 0 = no density, 1-10 = less density, 10-20 = sufficient density and > 20 = very high density, thus it can be concluded that Neritidae in coastal waters of Seri village is no density.

Abstract

Education and teaching focusing on the interaction between educators with educated or teachers with students. The interaction of teachers and teaching in improving stundent learning outcomes especially on biological materials, desperately needs attention, motivation, and interest. It almost entirely uses a good teaching style. This study was conducted for 1 month starting from 05th of November until 05th of Desember 2021. The purpose of this study is to influence of teacher’s teaching style (Variable X) and motivation of student learning outcomes in Biology at SMP Hang Tuah Lantamal IX Ambon by taked sample of 35 respondents, are the students of class VIII. The results showed that there is a significant influence or perfect correlation between teacher teaching styles on the motivation of learning results ofhuman’s blood circulation system in grade VIII of SMP Hang Tuah Lantamal IX Ambon. It is provenby the product moment correlation value of pearson rarithematic = 1.00 when compared with rtable = 0, 334 and according to table interpretstion of pearson correlation coefficient. Thus the hypothesis H1 which states there is a significant influence between teacher teaching style on student learning outcomes motivation.

Abstract

Nerita sp. is a type of gastropod that is commonly consumed by the people of Ambon Island, especially in the villages of Hutumuri and Latuhalat, and has the potential to be an alternative food source. However, its nutritional content has not been studied in detail. This research aims to analyze the proximate content, including moisture, ash, protein, fat, carbohydrates, and fiber, in Nerita maxima and Nerita costata from both locations. The study used a descriptive approach with random sampling techniques from the waters of Hutumuri Beach and Latuhalat Beach. Proximate analysis was conducted in the laboratory using the standard AOAC (Association of Official Analytical Chemists) methods.The analysis results show that at Hutumuri Beach, Nerita costata has a moisture content of 79.24%, ash 1.18%, protein 12.80%, fat 1.79%, carbohydrates 2.16%, and fiber 0.18%. Meanwhile, Nerita maxima has a moisture content of 81.30%, ash 1.10%, protein 13.90%, fat 1.72%, carbohydrates 1.66%, and fiber 0.19%. At Latuhalat Beach, Nerita costata has a moisture content of 76.80%, ash 1.48%, protein 17.02%, fat 2.75%, carbohydrates 1.49%, and fiber 0.20%. Whereas, Nerita maxima has a moisture content of 78.31%, ash 1.44%, protein 15.47%, fat 2.90%, carbohydrates 1.51%, and fiber 0.23%This research shows that Nerita costata and Nerita maxima from the waters of Latuhalat have higher protein and fat content compared to those from Hutumuri. This indicates that the more fertile and rocky water environment of Latuhalat supports better nutritional value, making these two species potential alternative food sources for the community.
