This study investigated the accumulation of Zn in the earthworm Aporrectodea caliginosa after 15 days of exposure. The worms were grown in media with different concentrations of Zn between 750 and 1500 ppm. Each treatment consisted of three replicates, containing 30 worms. A control group without Zn was also used. Data were analyzed by using Duncan Multi–Range. The results revealed that A. caliginosa had a strong ability to accumulate Zn in its tissue compared to the control group. It was noticed that the increase of the heavy metal in the worm´s tissue is associated with the elevation of the metal in its media. The results show a significant loss of weight in the worm´s body and loss in the growth rate; they also shown a decrease in specific growth rate. Moreover, there was a significant decrease in the worm length, showing a high effect, especially after 15 days of breeding with all concentrations used in this study. The researchers recommend using earthworms to purify the soil from contaminants because earthworm has a great ability to get rid of all pollutants, whether metals or pesticides or parasites, especially in industrialized countries and agricultural lands.","PeriodicalId":17741,"journal":{"name":"Jurnal Riset Biologi dan Aplikasinya","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77467002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although its abundance in nature has begun to show signs of decreasing, studies on this species are still very limited. This study aimed to examine indicators that can be used to determine the sex of A. rosettis individuals. Acaudina rosettis samples were collected from Madura strait in the mid of Hijri month for three months. The sea cucumber samples were then dissected. Body wall without viscera and gonads was weighed. The gonads were then characterized macroscopically and microscopically, prepared into histological slides with hematoxylin-eosin staining. The results showed that A. rosettis samples could be classified into three sex groups based on the type of gamete cells observed in the tubules; male (spermatogenic), female (oogenic), and undetermined sex (no gamete cells found). Gonads had three colors; yellow, pink, and orange and were in five stages of reproductive phase; gametogenesis (G), mature (M), spawning (S), and post-spawning (PS). Male samples had yellow and orange gonads, female samples were pink and orange, and all undetermined sex were orange. The G gonads were yellow and orange, M were yellow and pink, while S and PS were orange. Body wall and gonad weight at the same reproductive phase did not show any difference between males and females. Based on the results, gonad color can be used as an indicator of sex determination, but only in G and M reproductive phases.","PeriodicalId":17741,"journal":{"name":"Jurnal Riset Biologi dan Aplikasinya","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77340053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This ecosystem provides a lot of functions for the living organism inhabiting here, such as fishes, mollusks, echinoderms, crustaceans, ect. The mangrove crab is one of the common crustaceans that can be found in the mangrove. This Purtunidae crab is very popular due to their role in the food chain as well as for the economic income that has a high value in the market. However, overexploitation may decrease the crab population. This study aimed to investigate the abundance and occurrence of the mangrove crabs from Munjang mangrove, Bangka Belitung Island from August 2020 to June 2021 using baited traps with the line transect method at four zones. A total of four species of mangrove crabs, Scylla olivacea, S. paramamosain, S. serrata and S. tranquebarica, were found in this location and dominated by S. serrata. Shannon diversity index (H’) was a in low category (<1), evenness index range (J) from 0.35 to 0.89, and there was dominant species in this study. The bed sediment iswas dominated by the muddy clay substratum except in zone 4 with sandy. Overall, this location is a suitable habitat for the Scylla spp. And better management is urgently needed before these crabs are exploited by humans.","PeriodicalId":17741,"journal":{"name":"Jurnal Riset Biologi dan Aplikasinya","volume":"116 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79732735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth of fungi depends on the chemical composition of the environment in which it grows. The growth media of fungi must contain high carbohydrates as a source of nutrients and high nitrogen content. One of the carbon sources that fungi can use in the growth process is glucose. BR 2.2 isolate is an oleaginous fungus capable of accumulating 28.44% lipids from the total dry biomass with glucose as a carbon source in 50 mL of growth media. Therefore, this study was conducted to determine the effect of variations in the volume of media and incubation time on the production of biomass and lipid isolate BR 2.2. Biomass and lipid production were analyzed at media with additional water volumes of 10, 20, 30, 40, and 50 mL with 48, 96, and 144 hours of incubation times. The results showed that lipid accumulation and biomass production increased with the reduction of water content in the growth media and reached the highest number in the media volume of 20 mL with an incubation time of 144 hours, i.e., 0.87±0.04 g/L and 12.53±0.29 g/L. It can be concluded that biomass and fungal lipid increased along with incubation time and nutrient concentration.","PeriodicalId":17741,"journal":{"name":"Jurnal Riset Biologi dan Aplikasinya","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82574431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
