Abstract

The large demand for grouper conduce increase production intensively in various ways, by increasing the production of grouper aquaculture raises causing new problems, one of which is infection with VNN disease. The use of antibiotics to treat VNN infections is prohibited or no longer recommended by the government. An alternative way to deal with VNN infection is by increasing the body's immunity in the fish itself. One effort that can be done to increase the body's immunity in grouper is by administering Brachionus sp. protein extracts. This research was conducted to determine whether the Brachionus sp. has an effect on the immune system in cantang grouper (Epinephelus sp.) as indicated by the emergence of Cluster Differentiation-8 (CD8) expression in fish that have been infected with VNN. The proteins contained in Brachionus sp. that has three type molecular weight (122.73 kDa, 75.49 kDa, and 13.77 kDa) potential as an ingredient for treating VNN-infected fish. It is hoped that this can improve the immune system in Epinephelus sp. infected with VNN. Protein Brachionus sp. given by injection at a dose of 35 µl, 105 µl and 170 µl per 150 gr Epinephelus sp. 105 µl was the best concentration in boosting the immune system in the tested Epinephelus sp., as indicated by a decreased CD8 count.

Abstract

Currently and in the future, tourism is expected to make the biggest contribution to increasing the country's foreign exchange in the government's efforts to realize people's welfare and prosperity. One form of tourism product as a derivative of the concept of sustainable tourism development is the concept of ecotourism development. This study aims to map the research that has been carried out related to ecotourism in Indonesia. Data were obtained from scientific papers published on Google Scholar from 2010-2022 and there were 985 published scientific papers consisting of 968 from journals, 16 from proceedings, and 11 from books. Bibliometric analysis was carried out using the Vos Viewer application. The results of the study show that Indonesia has many tourist areas that can be developed into ecotourism areas, and these can be used as objects of research on ecotourism, but during the last 10 years research has only been conducted in a few areas. In addition, research on the same thing is often carried out in different research locations. This is the weakness of research on ecotourism in Indonesia. Thus, it is concluded that there are still many areas and keywords that are different and related to the concept of ecotourism which can be used as research subjects in Indonesia. research on the same thing is often done with different research locations.

Abstract

The split attribute in the decision tree algorithm, especially C4.5, has an important influence in producing a decision tree performance that has high predictive performance. This study aims to perform an attribute split in the C4.5 algorithm using the value of the termination coefficient (R2/R Square) which is combined with the aim of increasing the performance of the model performance produced by the C4.5 algorithm itself. The data used in this research are public datasets and private datasets. This study combines the C4.5 algorithm developed by Quinlan. The results in this study indicate that the use of the R2 value in the C4.5 algorithm has good performance in terms of accuracy and recall because three of the four datasets used have a higher value than the C4.5 algorithm without R2. Whereas in the aspect of precision, it has quite good performance because only two datasets have a higher value than the performance results of the algorithm without R2.
