Abstract

The research with the aim to know the effectivity (yield gap) of the application of Streptococcus agalactiae vaccine (pure whole cell) in prevention of streptococcosis on tilapia (Oreochromis niloticus) culture has been carried out. The isolate of S.agalactiae – N14G was used as a master seed on vaccine production. Priming vaccination was administered by immersion method, and booster vaccination was taken th place two months latter by oral method. Challenge test at the lethal dose (LD50) against active bacteria was done at 14 days post booster vaccination, and observation was taken place for 14 days post artificial infection. The results of the research showed that the highest survival rate and relative percent survival (RPS) was found in group treated with Streptovac vaccine (S. agalactiae and A. hydrophila combination) (65.58% and 35.36%) followed by S. agalactiae vaccine (52.08% and 10.01%). The lowest survival rate was found in control group (46.75%). The result of confirmation effectivity of the vaccines by challenge test in the laboratory showed that the highest survival rate and relative percent survival (RPS) was found in S. agalactiae vaccine (50.00% dan 37.50%) followed by Streptovac vaccine (40.00% and 25.00%), and the lowest survival rate was found in control group (20.00%). Vaccination is better than the non vaccinated.

Abstract

AbstractThis thesis presents a study that focuses on the study of oral literature, namely folklore. The rapid development of Science and Technology has led to a reduction in speakers and listeners of folklore, for that careful study of folklore texts needs to be done. The focus of the problem in this study is the structure, function, context and cultural value of the story and its implementation plan in learning folklore in schools. The method used is descriptive analysis. This research uses structural approach and sociology of literature. The data source in this study is in the form of folklore told by speakers. The steps of data collection are done by recording, transcribing, editing, translating, identifying and classifying. The data is then interpreted and analyzed by providing interpretations of meaning according to the problem under study. The results of the analysis of this study are: (1) the structure of the story, there is a forward plot, there is a human character, and there is a setting in the form of place, time setting and social setting; (2) the function of the story, found five functions, namely: as a means of entertainment; as a means of education and inculcation of moral values; as a cultural validator; as a means to pass down traditional ways of life, customs and habits; and as a tool so that the norms of society will always be obeyed by their collective members; (3) the narrative context consists of three contexts namely situation context, cultural context, and social context; (4) cultural values consist of human relations with God, human relations with oneself, human relations with the natural surroundings, and human relationships with each other; and (5) the results of this study can be implemented in Bahasa Indoneisa learning in schools because there are positive values that can be learned by students, namely in KD 3.7 identifying the values and content contained in folklore both oral and written, and KD 4.7 retell the contents of folklore heard and read. Keywords: Context, Cultural Values, Folklore, Function, Structure

Abstract

Abstract Mahseer "dewa" (Tor soro), snakehead "gabus" (Channa striata), and bagrid catfish "baung" (Hemibagrus nemurus) are local specific fish species that are promising to be developed as freshwater aquaculture commodities in Indonesia. Disease cases/outbreaks in those fish farming have often been reported, however, there is not much information on the epizootiology and disease status of those fish species. The susceptibility of those fish to parasitic infection was evaluated by natural and artificial infection. Natural infection was conducted by randomly sampling 20 fish at 5-day intervals and lasting for 30 days. In artificial infection, 150 tested fish cohabited with 40 parasite-carrying fish that were known to be definitely infected by the parasite. The observation was carried out by sampling 20 fish at 5-day intervals and lasting for 30 days. The results showed that the three fish species were susceptible to infection with Trichodina spp, Epistylis spp, Tetrahymena spp, Ichtyophthirius multifiliis, Dactylogyrus spp, and Gyrodactylus spp, while the helminth parasite Pallisentis nagpurensis (Acanthocephala) was only identified in snakehead. A number of parasites such as I. multifiliis, Dactylogyrus spp., and Gyrodactylus spp. are likely to be potential obstacles in the cultivation of those fish species, especially in hatcheries and nurseries. Keywords: mahseer, snakehead, bagrid catfish, parasites
