Abstract

Successful biodiversity cultivated in freshwater fish is farmed whitefish, tiger shrimp, vannamei shrimp and. While the grouper duck (Cromileptes Mozambique) export market prospects have never tried. This research would like to know how the seed of acclimatization grouper duck into fresh water against the survival rate and growth response. Using random design complete 5 x 4 treatment, seed samples with long range 12 cm, weight 22 gr. Acclimatization of habitat in salinity of 30 ppt ppt 4. Moderate decrease in salinity 0.0 A0 is the ppt/day (controls), A0,5 (0.5 ppt/day), A1 (1 PPT/day), A1.5 (1.5 ppt/day), and A2 (2 ppt/day). Data were analyzed with the survival rate of the t test (P ≤ 0.05) the results show a decrease in salinity of 0.5 ppt/day 35% real different with controls 92.5%, but is superior than the three other treatments (A1, A1.5 and A2) dead all before reaching 4 ppt. While the growth rate data were analyzed with anova followed duncan test (P ≤ 0.05) the results show A0.5 0.60% no different with real control of 0.61% real but different (fastest) compared to three other treatments (A1, A1.5 and A2). The conclusion is grouper duck capable cultivated in brackish water 4 ppt (mesohalin) through acclimatization with decreased salinity of 0.5 ppt/day.

Abstract

The study aims to find a comparison of the effectiveness of interactive learning media with powerpoint media on the results of studying the genetic substance of class XII students at Hang Tuah 4 Surabaya high school. The method used in this study is an experiment with research design is a nonfunctional control design group. The population in this study is 33 XII High School Science students Hang Tuah 4 Surabaya. The sample used in the study is to group into two large groups by odd absenbs and even Numbers.Research obtained from: (1) the average student study results from both groups, experiment groups 1 and experiment groups 2, were obtained that the average for experiment groups 1 of 80,63, for experiment groups 2 of 65.88. (2) based on the t test results on both groups, the result of thitung gained by 0.017, in which case it is stated that thitung is smaller than the ttabel 0.05. Based on the average results of student study and hypothetical tests made by researchers it results that the use of interactive learning medium suggests a postif and is more effective in the increased study of students the genetic substance of a class XII Science 2 High School Hang Tuah 4 Surabaya

Abstract

Indicators are substances that can be used to show the properties of a substance through a special change in its color. The types of plants used in this study as natural indicators are found in the surrounding environment for example purple sweet potatoes (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L). This research was conducted in 5 stages: 1) cut the purple sweet potato and butterfly pea into small pieces and then mash until smooth: 2) pour 5 tablespoons of alcohol and then leave until it settles; 3) pour the extract on 3 test tubes to test acid, base, and control; 4) drip the test solution on 2 test tubes; 5) then do testing to identify discoloration in purple sweet potato extract and butterfly pea a large amount of anthocyanin content in butterfly pea (Clitoria Ternatea L) affects the results of acid and alkaline testing so that the test results on butterfly pea extract (Clitoria Ternatea L) show a clear change in color. The purpose of this study is to identify the effectiveness of purple sweet potato extract (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L) as natural indicators of acid-base so that it can be used as an alternative learning medium.

Abstract

This study aims to determine the identification of acid-bases with natural indicators. This, is done because acid-base testing uses a lot of litmus paper. In dragon fruit extract and turmeric extract, there is a more concentrated color pigment content to determine the acid-base concentration. So we want to increase its sensitivity to detecting acid- bases. The method used in this study is experimental. The results of the study can be used to assist the public in knowing the benefits of dragon fruit and turmeric to detect acid-base solutions.
