Abstract

Abstract. Biodegradable plastic is a low molecular weight polymer material that almost all of its constituent components come from renewable materials. One of the natural materials that can be used as biodegradable plastic raw materials is starch derived from sago. Sago is one of the plants that has starch about 75.88% so it has a potential to be used as raw material in the manufacture of biodegradable plastics. To improve the structure of biodegradable plastic, chitosan was used which was derived from the scales of Katamba fish. Synthesis of biodegradable plastic from sago extract by adding chitosan derived from Katamba fish scales which then analyzed its morphology characteristics by SEM (Scanning Electron Microscope). This research used pure experimental research design in laboratory (true experimental research), the research was the making of starch-chitosan composite as the main material in the production of plastic which was then done morphological analysis. The results of this study revealed the biodegradable plastic with the appearance of clear white transparent, smooth surface, and medium elasticity with the morphological characteristics through SEM observations with 5μm-20 μm magnification seen a solid plastic surface with a flat texture. Keywords: biodegredable plastics, extract of Sago, Katamba chitosan

Abstract

Abstract. Cassava has a low selling value because it contains cyanide acid (HCN) which is deadly, while papaya seeds contain flavonoids, tannins and saponins are beneficial to health. How to increase the selling value of cassava and papaya seeds by processing modified cassava milk with the initial method, ie cleaned cassava, soaked 72 hours with 4% w / v NaHCO3, soaked 1 hour with 15% w / v salt, soaked 24 hours with 0,1% w / w starter Bimo-Cf, then stirred at 75-80 oC and fermented for 3 days using Fermipan (Saccharomyces cerevisiae) and Raprima (Rhizopus oryzae). The fermentation results were added aquadest and papaya seeds (20 and 40% w / w) stirred at 70-75 oC. Then dried to produce modified cassava milk. Modified cassava milk was intervened in mice for 28 days with dysplinemic treatment. The results showed the greatest decrease in HCN content in modified cassava milk with addition of 40% w / w of papaya seeds at Saccharomyces cerevisiae (2.052 ppm) and Rhizopus oryzae (2,160 ppm). The best increase in protein content was obtained by addition of 40% w / w of papaya seeds in Rhizopus oryzae (4.06%) and Saccharomyces cerevisiae (3.30%). The decrease of total cholesterol total of the best dysplinemic rats was obtained from modified cassava milk of R. Oryzaae variation with the addition of 20% papaya seeds by 60.45% and 40% papaya seeds by 40.63%..Keywords: papaya seed, cholesterol, Rhizopus oryzae, Saccharomyces cerevisiae, cassava.

Abstract

Abstract. This study aimed to know the impact and contribution of awareness to group performance in learning chemistry. The purposive sampling technique is the sampling technique used. Data analysis technique used is multiple linear regression, partial regression coefficient, and correlation. The samples used 43 chemistry students. Data collection techniques used observations, instruments of emotional intelligence and ECGN (Emotional Competence Group Norms). The results showed that except for X1, the constant value of regression increased by the value of X2-X5 variable that increased, it means that there was a slight increase. The t test shows that there is no impact of self awareness on group performance with points t h < t tb (-0.817 < 2.026), lack of contribution of variable X to Y with R Square value 8,1% (0,081), and sign> 0,05.Keyword: Self-Awareness, Group Performance, Learning Chemistry.

Abstract

Abstract. Membrane layer ia a semipermeable material that serves as a separator based on its physical properties. One type of this material is a silica-based membrane that offers higher selectivity in the desalination process of water. However, this membrane also has a weakness in hydro-stability that will ultimately affect the final desalination water results. The aim of this research is to know silica gel fabrication using sol-gel process and under various pH from 1 to 9. The precursorused was TEOS which is then applied as a layer on top of membrane support for water desalination process. The method was employed TEOS as a precursor, ethanol, HNO3 and NH3 with a two-step acid-base catalysed sol gel process method at 500C for 3 hours. In order to characterize this thinnfilm, the silica sil was dried at 600C for 2 hours and characterized using FTIR. It was found that there are several peaks at wavelength 1084, 962 and 800 cm-1 on sol-gel with pH 6. Siloxane groups can be seen at wavelengths 1084 cm-1 and 800 cm-1 while silanol group at peak 962 cm-1. Thus, the silica thin film membrane pH 6 shows a tendency to form a good micro and mesoporous material applied in separating salt content in the feed solution compared to the other sols.Keywords: membrane, silica sol, TEOS, xerogel

Abstract

Abstract. Thinking skills is strongly influenced by the working of brain. The brain is the center of all activities including thinking. Therefore, the learning that regard and develop brain potential to develop high order thinking skills in students is required. The reason to do this research is because the lack of training given to students in optimizing the ability of their brain in thinking, which generally use the lower order thinking such as remembering and memorizing. The use of Brain-Based Learning (BBL) strategy will be an opportunity for students to develop their thinking skills for their cognitive achievement. This research aims to determine the effectiveness of BBL strategy to metacognitive skills of biology students in Borneo Tarakan University. This is quasi experiment research with pretest-posttest control group design. Population in this research is all of biology students who program Cell Biology course. Students of A and B class are the sample of this research. Data analysis used is descriptive and inferential statistic technique. The results showed that BBL strategy is more effective influencing metacognitive skills compared with multistrategy. The average score in the class with BBL is 51.81 higher than the average score on the class taught with multistrategy that is 41.94.Keywords: Brain-Based learning, thinking skills, metacognitive.
