Abstract

Skeletonema costatum (Greville) Cleve (Bacillariophyceae) is the unisel photosynthetic microalgae’s diatom which has the silica as the main composition of its cell walls. Diatoms have some life phases that can be observed in its batch culture The purpose of this research is to study the population growth of the diatom Skeletonema costatum populations in the f/2 medium and Conway medium of the growth curve is formed. This study also aims to determine the generation time and instantaneous growth rate of this the diatom species in both medium, in order to know which one is more appropriate medium for Skeletonema costatum.The batch culture of S. costatum was applied at f/2 medium and Conway medium with three replications for 7x24 hours in a sterile condition. Environmental parameters (pH, salinity, and temperature of the medium) were measured periodically. The population growth of the culture reached the lag phase in the first 24 hours, the exponential phase in the second 24 hours, whereas the stationary phase was in the third 24 hours. The growth of S. costatum in both medium were not significantly different. Skeletonema costatum growth rate in f/2 medium were 0.0282 cells/hour and its generation time were 25.5420 hours. On the other hand, Skeletonema costatum growth rate in Conway medium were 0.0228 cells/hour and its generation time were 30.3728 hours. This study proved that the growth of Skeletonema costatum populations in f/2 medium and Conway medium tends to be similar (Sig. 0.325, α = .10).Keywords: Skeletonema costatum, f /2 medium, Conway medium, growth rate, generation time

Abstract

Lighting is an important parameter of the poultry production because of strong exogenous factor in controlling a wide variety of physiological processes and behavior. The lighting allows the birds to establish harmony and sync or equate many essential functions, including body temperature and various steps that facilitate metabolic feeding and digestion. The lighting also stimulates the secretion of some hormones patterns that control most of the growth, maturity or adulthood and reproductionThis research aims to assess the influence of light color on the body weight and carcass kampung chicken. The main independent variable is the color red, blue and white. The main dependent variable consists of body weight and percentage of carcass. The variable control is the number of rations, health management, a type of chicken, and the age of the chicken.The results show that there is no real difference in the influence of different color variations of the lighting body weights (P>0,05), and the carcass of a chicken (P>0,05).Keywords : lighting stimulation, kampung chicken, body weights, carcass

Abstract

A study with R & D method focusing on improving the skills of arguing in the concept of human physiology was conducted through the development of model of Assessment Argumentative. The model was outlined in the form of argumentation observation sheet(LOAKp). A number of sixth semester students of Biology Education attending subject of Human Physiology (n=121) were involved as research subject. The implementation study applied Research and Development design. TAP (Toulmin Argumentation Pattern) comprising components of claim, warrant, backing and rebuttal had been used to analyze argumentation discourse. Arguing skills were qualitatively and quantitatively measured by complexity of argumentation pattern (PWArKp). The instrument of assessment argumentative model as observation sheet of argumentation discourse which had been implemented through stages (scaffolding) with particular standpoints. The results show that the aspects of PWArKp are generally developed from the early stages to the final stage. However, complexity of argumentationdiscourse still need to be improved because some standpoints have responed on level 1 or leve 2. Thus skills of arguing of students in complexity of argumentation pattern aspects need further in depth study by providing students more opportunities to engage in argumentative discourse.Key words: Assessment Arguementative, argumentation skill, human physiology concepts
