STEM-based learning innovations have been massively developed especially related to 21st Century skills. This study was done to explore a relationship between creative thinking and science achievement through the implementation of integrated STEM-based module on Reproduction topic. A quasi-experimental study involved pretest-posttest non-equivalent group design with sample of 60 eighth graders from a boarding school in Baling, Kedah, Malaysia. The samples was divided into two groups - 30 students of treatment group and 30 students of control group. The data were collected from pre-post-Reproduction Test Questions (RTQ) scores and pre-post-Creative Thinking Test Questions (CTTQ) scores. Pearson Correlation and one-way ANOVA at a significance level p < .05 were performed in analysing data. Findings reveal no statistically significant relationship between creative thinking and science achievement for both treatment group (r = .220, p = .243) and control group (r = .308, p = .098). Besides, there is a statistically significant and moderate and positive relationship between creative thinking indicator of fluency and science achievement (r = .463, p = .010) of the treatment group. In conclusion, general finding is an evidence that between creative thinking and science achievement shows a consistency in whatever teaching strategy implemented. In which, educators need to realize that academic achievement does not necessarily be a necessity in shaping one’s creativity. Therefore, further study is needed to investigate the relationship between these variables in the execution of STEM teaching and learning so that the findings can be generalized to a larger population.

Nowadays, many researches were conducted in minimizing tissue culture technology due to the overhead of cost needed. The purpose of this study was to investigate the effects of using five kinds of organic additives at four level concentrations responsive to the number of shoots produced for eight weeks in culture. Stem segment explants of Celosia sp. were cultured on MS medium that have been supplemented with different kinds of extract juice that serve as organic additives which are mature coconut, young coconut, papaya, banana and tomato at 20, 30, 50 and 70 ml L-1. The numbers of shoot on each explant were recorded and the mean of ten replicates explants were calculated. Among the media used, young coconut water at 70 ml L1- induced the highest shoot regeneration (14.21+/-8.26), followed by mature coconut water at 50 ml L-1 (13.14+/-10.33). Banana and tomato juice promote highest shoot regeneration of stem segments at 50 ml L-1 that produced 9.57+/-4.68 and 9.28+/-5.82 shoots per explants, respectively. While the lowest concentration which at 20 ml L-1 of papaya juice showed highest shoot regeneration (10.50+/-3.45) produced among the three other concentration tested. Statistical results showed that there were significant differences interactions effects (p<0.05) in terms of number of shoot regenerated between the types of extracts juices determined by ANOVA test. Comparing number of shoots regenerated that were cultured in control media, it showed higher than all of experimental medium composition. There were no big different in cost required in preparation of control media and the experimental media. Applications of five kinds of local fruit in tissue culture media should be considered since it responsive in shoot regeneration.

Seaweeds, mainly brown species, have long been used as soil fertilizers and have several advantageous effects of spraying their crude extracts on plant growth. Unlike chemical fertilizer, biofertilizers derived from seaweeds or other organisms are usually biodegradable, non-toxic, non-polluting and nonhazardous to humans, animals and birds which will benefit to agriculture sector. In this study, four different concentrations (0.50; 1.00; 2.50; and 5.00 mg/L) of four different solvents extract (hexane, dichloromethane, methanol and water) were used to determine the effect on in vitro seed germination of Capsicum annum and Lycopersicon esculentum. The results showed that concentration 2.50 mg/L can be classified as optimum concentration for seedling development of Lycopersicon esculentum and this study has proven that DCM is the effective extract solvent that result in promoting hypocotyl and root growth of tomato plant. For Capsicum annum, hexane extracts solvent of Sargassum sp. Was found to be more effective than other extracts in promoting seedlings development. Phytochemical screening of Sargassum sp. exhibited the presence of alkaloids and terpenoids as the dominant compenants in all extract.

The seed of Sandoricum koetjape (Burm.f.) Merr., a member of Family Meliaceae, had been screened for its phytochemcial components and extracted using hexane, methanol, and water for antimicrobial activity towards three bacteria, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus. Phytochemical screening showed that the S. koetjape's seeds contain high amount of alkaloid and flavonoid. The crude methanol extracts showed inhibition zones towards the three bacteria with minimal inhibition zones of 0.25 mgL -1 for B.subtilis and of 0.50 mgL -1 for both P.aeroginosa and S.aureus.
