Abstract

Motile Aeromonas Septicemia (MAS) disease caused by Aeromonas hydrophila is a common pathogen that attacks freshwater fish commodities, including triploid as the new strain of striped catfish. This study aimed to test the resistance of triploid striped catfish to MAS infection before being released to farmers as a new commodity to increase national striped catfish production. The test was carried out for two months at the Sukamandi Fish Breeding Research Institute, Subang by injecting A. hydrophila into triploid and diploid striped catfish. The challenge test was carried out by injecting the cultured A. hydrophila with a density of 107 cfu.mL-1 as much as 0.1 mL.ind-1 at fish intramuscularly in all treatments, while in the Control (-) treatment, 0.1 mL of PBS solution was injected.tail-1. The test striped catfish used for each treatment were 10 individuals measuring 9.23 – 9.65 cm, and weighing 7.1 – 9.23 g. Survival parameter data and blood description were analyzed quantitatively using Microsoft Excel 2010 and SPSS version 16.0 software with analysis of variance (ANOVA) at a 95% confidence interval. The results of re-characterization with biochemical tests showed that A. hydrophila were gram-negative, oxidase and catalase positive, motile, could fermentatively convert sugar, and could grow in blood media. The survival of triploid striped catfish after the test was 95%, total erythrocytes on day 7, and total leukocytes on the first day were significantly different from diploid striped catfish. Thus, it can be concluded that striped triploid striped catfish are more resistant to infection with A. hydrophila than diploid.

Abstract

Abstract Calculation of the beginning of the month and conversion of the Gregorian calendar to Hijri based on existing data. Calculating the beginning of the month is essentially calculating the position of the sun according to the established criteria. The position of the sun is not always the same every day. This research uses library research in the sense of looking for articles, theses, journals and books related to the author's title. The approach that the author uses is thesyar'I approach and the astronomical approach. According to the data source, research data is divided into two data, namely primary data and secondary data. The results of this study indicate that the perspective of astronomy on the calculation of the beginning of the month and the conversion of the Christian calendar to the Hijri used is the reckoning or calculation method. As for the month samples taken, namely Hisab at the beginning of Shawwal, Zulqaedah and Dzulhijjah 1444 H where istiqmal occurs, the number of days is made up to 30 days. Where the height of the new moon does not meet predetermined criteria. The conversion of the Gregorian calendar to the Hijri is used as a benchmark is the author's date of birth and the date of birth of the author's parents indicating that the calculation is in accordance with the method of astronomy, namely reckoning urfi. The implication of this research is that it is hoped that the government or religious leaders can broaden the horizons of those who already know or do not know about the procedure for calculating the beginning of the month and converting the Christian year to the Hijri year correctly and correctly in a modern way. It is hoped that students, especially the faculties of shari'ah and law and the department of astronomy, will be able to play an important and active role in providing knowledge to the public regarding the procedure for calculating the beginning of the month and converting the Christian year to the Hijri year.
