Publisher : Faculty of Mathematics and Natural Science, Universitas Negeri Yogyakarta

Penelitian ini bertujuan untuk memudahkan identifikasi protein atau turunannya dalam matriks yang kompleks dengan molecularly imprinted polymer (MIP) yaitu imprinted PMAA-BSA. PMAA-BSA disintesis dengan Asam Metakrilat (MAA) sebagai monomer, Etilen Glikol Dimetakrilat (EDMA) sebagai cross-linker, BSA (Bovine Serum Albumin) sebagai template pencetak molekul protein dengan benzoil peroksida (dalam kloroform dan benzena) dengan metode polimerisasi bulk secara termal. Imprinted PMAA-BSA terbentuk setelah tahap ekstraksi template BSA dari PMAA-BSA dilakukan. Hasil penelitian menunjukkan bahwa PMAA-BSA berhasil disintesis dengan komposisi MAA : EDMA : BSA (20 mg/ml) = 5 : 1 : 1 (mol) dengan konsentrasi benzoil peroksida sebesar 0.5 mg/ml. PMAA-BSA memiliki BM 3440 g/mol, meleleh pada 131,730C, dan terdegradasi secara termal pada 374,980C dengan kehilangan berat hingga 69,78%. Pada spektra IR PMAA-BSA terdapat pita serapan penciri gugus amida sekunder, pada 1634 cm-1, sedangkan spektra IR PMAA tidak menunjukkan profil tersebut. Pita serapan penciri amida sekunder pada spektra IR imprinted PMAA-BSA menunjukkan masih ada penciri amida sekunder dengan intensitas yang lebih rendah. Pengukuran filtrat BSA pada tahap pembentukan imprinted PMAA-BSA dan tahap ekstraksinya menunjukkan recovery dan reproducibility terbaik 94,85% dan 8,029%. Kata kunci: polimer, MIP, BSA

Abstract This study aims to determine the optimum mass, optimum agitation times and the effect of the concentration of direct red dye was adsorbed by charcoal of ambon and kepok banana peels. And to determine the influence of activator concentration of NaOH on the adsorption capacity of ambon and kepok banana peels on the adsorption of direct red dye. The subject of this study is the ambon and kepok banana peels. The object of this study is the efficiency of adsorption. The parameters in this study are the mass of adsorbent, agitation times, dye concentrations, and the concentration of NaOH activator. Adsorption capacity of banana peels to direct red dye is determined by the difference of concentration before and after adsorption. The concentration of dye was determined using a spectrophotometer at an optimum wavelength of visible light. The result shows that the optimum mass and agitation time for direct red dye adsorption which are adsorbed by the charcoal both of ambon and kepok banana peels adsorbent is 0.5 grams per 50 mL of the adsorbate and 2 hours, respectively. Direct red dye concentration does not affect the efficiency of adsorption ambon banana peel charcoal but influences the efficiency of adsorption kepok banana peel charcoal. The greatest adsorption ability of ambon and kepok banana peels are given by NaOH activator at 0.5 M and 1 M. Key words: banana peel, banana peel charcoal, direct red, agitation time

The edible film is an alternative packaging with renewable and safe materials. The edible film used is methylcellulose from nata de coco with polyvinyl alcohol (PVA) plasticizers and cinnamon oil additives. This research aimed to determine the effect of PVA on the mechanical properties of edible film and the effect of adding cinnamon oil on the character of edible film. PVA added were 5%, 10%, 15%, 20%, 25% and cinnamon oil added were 2%, 4%, 6%, 8%, 10%. The mechanical properties of the edible film were observed by tensile strength tester, whereas water vapor absorption by gravimetric method. The result showed the optimum mechanical properties of the edible film was addition PVA 15% which was 1.565 MPa. The more cinnamon oil was added, the mechanical properties of edible film tend to decrease, however, the water vapor absorption tends to increase. The addition of cinnamon oil also showed antimicrobial activity that the fungus did not grow on the edible film.

The movement of educational systems on the 21st century need to be change from linearity to systemic form. The aims of this research is to determine the effect of Chemistry Systemic Learning Approach (CSLA) toward Students’ Analytical Thinking Skills (SATS). A pre-experimental with pre-test and post-test design was adopted in this research. The population of this study were all of the students of public senior high school in Kulon Progo regency, Yogyakarta, Indonesia. Two classes from a public senior high school in those regency were cluster randomly selected as the research samples. A Systemic Test on Analytical Thinking (STAT) was used to collect the data of SATS, before and after the implementation of CSLA. The STAT covering four indicators of analytical thinking, they are differentiating, organizing, and attributing indicators. Meanwhile, the CSLA was integrated in the teaching-learning process and in the STAT, the CSLA was presented in the form of cyclic diagrams. The data of SATS on CSLA were analyse according to paired samples t-test and n-gain category analysis. The results of these analysis indicates that there was significant effect of CSLA on SATS. Moreover, the profile of SATS shows a satisfied improvement after the implementation of CSLA. Overall, a high n-gain category was reached that indicates the enhancement of students’ understanding of the inter-related concept in chemistry. This study gives a significant contribution on the use of CSLA to improve SATS. Hence, the used of CSLA should be emphasized on chemistry learning to promote students’ higher order thinking skills.
