Abstract

Every living organism has the ability to reproduce that aims to maintain the kind ( species). Sexual maturity conditions of  Drosophilla melanogaster will affect the outcome of the offspring ,that is a number of offspring and a kind offspring sex. Sexual maturation of female D. melanogaster individuals also greatly affect to the offspring conditions. Genetic research using D. melanogaster as an experimental material will be interesting and challenging for the university students . The purpose of this study was to determine: 1)The effect of age of female D.  melanogaster strains tx on offspring number and the sex of F1. 2) The research results will use as a guide to the preparation of the genetics lab. The study was conducted using a completely randomized design methods . Data were analyzed using analysis of variance of the path (oneway Anova) followed  further test by 5 % BNT test. Data showed the effect of age of female D. melanogaster strains tx on a number of offspring and the kind sex of F1 . The average number of offspring at various ages females are 149.38 . The average of are 72.03 and 77.34 of the female. After further testing with BNT in 5% of level indicates that the number of F1 offspring in females treatment aged 12 , 24 , 36 and 48 hours resulted in a lot of different number of offspring significantly with the number of female progeny from crosses age 60 , 72, 84 and 96 hours resulted in the number of little offspring. From the study it can be concluded that the age of the female D. melanogaster strains tx effect on a number of offspring and a kind of F1 sex of progeny . The older females ,the number of offsprings produced are less, because females decreased fertility and fecundity . Individual males have a higher mortality compared with all age female D. melanogaster strains tx . Keyword : Females Age , D. melanogaster strain Tx, Practical Guidelines .

Abstract

This study aims to compare the salt content (NaCl) in the leaves of several types of coastal plants that grow in different formations, namely Mangrove, Barringtonia, and Pres-Caprae. The study was conducted in the coastal area of Lais District, North Bengkulu Regency using direct survey methods in the field and laboratory analysis using a refractometer. The results showed that there were 10 species of coastal plants from three formations, namely Barringtonia, Mangrove, and Pes-Caprae. The highest salt content was found in the Acanthus species ilicifolius (2.75‰) from the Mangrove formation, while the lowest levels were found in Canavalia maritima (0.75‰) from the Pes-Caprae formation. The difference in salt content is thought to be influenced by the location of its habitat in the coastal area and its ability to adapt both structurally and physiologically so that it can survive in an environment with extreme salt content. The results of this study provide important information about the adaptation of coastal plants to salinity and can be the basis for further research on salt concentration in coastal plants.
