Abstract

Ectoparasites is a type of parasite that is generally found infecting the external organs of their host's body. Knowledge of the types of parasites and the host are reviewed as an effort to control parasitic attacks. This study aimed to examine the types of ectoparasites in various brackish aquaculture commodities. Research procedurewereincluding preparation of tools and materials, sampling, observation of clinical symptoms, necropsy, observation of parasites and data processing. This study used purposive sampling with 28 samples obtained from several locations consisting of 5 nemo fish (A. ocellaris), 2 tilapia (O. niloticus), 1 snapper (L. calcarifer), 3 crab (P. pelagicus), 5 mangrove crabs (Scylla spp.), 12 vaname shrimp (L. vannamei). The data obtained were analyzed descriptively by comparison between the commodities and the types of parasites found. The results showed that the clinical symptoms of each commodity were different, namely loss of appetite, inactivity, slow growth and morphological changes.Crab and mangrove crab were not showing clinical symptoms. Parasitic infections were found in all types of commodities except snapper fry, crab larvae, broodstock and vannamei fry. The types of parasites found were Cryptocaryon sp., Tricodina sp., Gyrodactilus sp., Ascarophis sp., Dactylogyrus sp., Octolasmis sp., Rabdostyla sp., Zoothamnium sp., Vorticella sp., Acinata sp. Each type of parasite has different characteristics, properties and control.

Abstract

Previous studies related to digestive enzyme activity have been carried out, but there is no information related to the effect of temperature on the trypsin-like activity and digestive amylase in Rsbora lateristriata. Therefore, the purpose of this study was to determine the effect of temperature differences on the activity of trypsin-like and amylase digestion of Rasbora lateristriata fish. The temperature treatments applied were 20, 30, 40, 50, 60, and 70ºC and each treatment was repeated five times. A total of 125 Rasbora fish with a body weight of 0.81 ± 0.09 grams were used in this study. Trypsin-like and amylase activities were measured using a spectrophotometer. The results showed that there were significant differences (p < 0.05) in the trypsin-like and amylase activities at different temperatures. The trypsin-like activity was not significantly different (p < 0.05) between 20-50ºC, but the activity was lower at 60-70ºC. Amylase activity at 30°C and 40°C was not significantly different (p < 0.05), but significantly different from 20, 50, 60, and 70°C. In conclusion, trypsin-like decreased activity at 60°C and amylase at 50°C.

Abstract

The presence of Hermetia illucens larvae in waste management systems is very beneficial because of their ability to degrade waste. The growth of Hermetia illucens larvae depends on the adequacy of nutrients contained in the growth media such as protein and fat. The purpose of this study was to determine the growth, density and nutritional correlation of pineapple and rice bran media on Hermetia illucens larvae. The study used a completely randomized design consisting of 5 treatments, namely: 1) 100% pineapple waste; 2) 75% pineapple waste and 25% rice bran; 3) 50% pineapple waste and 50% rice bran; 4) treatment of pineapple waste 25% rice bran 75%; and 5) 100% rice bran. Each treatment consisted of 5 replications. Hermetia illucens larvae were reared for 21 days in organic waste media. The results showed that Hermetia illucens larvae grew optimally on a combination of 75% pineapple waste and 25% rice bran, namely an average length of ±15.298 mm and an average weight of ±11.644 g (sig <0.05), while the population density of the larvae showed no significant difference between treatments. with a density of 0.023-0.024 fish/cm3. The results of Pearson correlation analysis showed that the nutrient content of the media such as protein, fat, ash, moisture content and crude fiber had an effect on the length and weight of Hermetia illucens larvae, but had no effect on the larval population density.

Abstract

A teacher's understanding of learning will be seen from how the teacher applies it in teaching and learning activities. A teacher must know the strategy in teaching. This is related to learning models, techniques, and learning methods. In addition, the teacher must also be able to create a conducive, safe, comfortable, and enjoyable learning atmosphere. So it is important for a teacher to explore related models, learning methods with new innovations. One of them is by integrating STEAM learning into these learning models and methods. So far, not much research has been done on STEAM-based learning models and methods in biology subjects. The purpose of this study was to analyze which learning models and methods are often used, as well as which materials are most often used to apply STEAM-based learning to high school biology material. This research is a qualitative descriptive study by distributing questionnaires via Google forms which are distributed via WhatsApp groups to high school biology teachers in Bogor Regency, with 48 people as respondents. The instrument is a questionnaire on the Google form which consists of 15 questions, which contain questions about the media that is often used in class, what models and methods are often used in biology subjects, as well as the teacher's knowledge of STEM, and in any material in biology subjects the teacher applies STEAM learning. The results showed that the most widely used learning model was the Problem Based Learning (PBM) model (43.8%), followed by Project Based Learning (PjBL) (20.8%). Teachers who use the discussion method 16.7%, the cooperative method 12.5%, and 6.3% use the lecture method. For knowledge about STEAM, the results show that 91.7% of respondents know about STEAM, and 68.8% of respondents have implemented STEAM-based learning. For the application of STEAM, most of it was done on material change and environmental preservation as much as 22.9%. The data obtained were analyzed qualitatively, then displayed in the form of pie charts and bar charts.
