The Correlation Between Vocabulary Mastery and Students' Reading Comprehension

Penelitian ini bertujuan untuk mengetahui apakah ada hubungan antara penguasaan kosakata dan kemampuan membaca siswa. Populasi dalam studi ini adalah kelas dua MIA 3 siswa SMAN 1 Sidomulyo. Ada 30 siswa sebagai sampel. Instrumen yang digunakan adalah tes kosakata dan tes membaca. Hasil perhitungan SPSS menunjukkan persentase rata-rata kemampuan membaca adalah 63,4% dan persentase rata-rata penguasaan kosakata adalah 60%, dan hasil perhitungan SPSS untuk korelasinya adalah 0,989. Koefisien korelasi lebih tinggi bahwa nilai kritis tabel (0,989> 0,32). Analisis statistik menunjukkan korelasi antara penguasaan kosakata siswa dan membaca adalah signifikan (p .32). The statistical analysis showed that the correlation was significant (p< .01; p= .000). Therefore, the null hypothesis (H0) is rejected and the alternative hypothesis (H1) is accepted

Detection of Antimicrobial Compounds Isolated from Several Tropical Lentinus by Bioautographic Method

The antimicrobial compounds extracted either from culture filtrates or mycelia of several tropical Lentinus species could be detected their existences and locations by bioautographic method. For this purpose, the crude extracts were deposited as spots on silica gel plates and developed in a n-butanol-acetic acid-water mixture (3:1:1). The dry silica gel plates were then seeded with Bacillus subtilis and incubated at 35 oC for one night. On these plates, the extracts were separated into several bioautographic spots or growth inhibition zones. In parallel, the spots were detected by viewing with chemical revelations or under ultraviolet radiations at 254 nm or 366 nm. On silica gel thin-layer chromatograms, the crude extracts of Lentinus were separated into several bioautographic spots; for the filtrate extracts of L. squarrosulus 55A into three spots (Rfs 0.75, 0.50, 0.17), the mycelial extracts of L. sajor-caju LSC8 into two spots (Rfs 0.77, 0.54), the mycelial extract of L. torulosus LU3 into two spots (Rfs 0.77, 0.48), the filtrate extracts of L. cladopus LC6 into one spot (Rf 0.76) but the mycelial extracts of this mushroom separated into two spots (Rfs 0.79, 0.54), the filtrate and mycelial extracts of L. cladopus LC4 into three spots respectively (Rfs 0.75, 0.61, 0.45 for the filtrate extract and Rfs 0.83, 0.73, 0.60 for mycelial extract). By this method, the active compounds were detected directly and it is a usual method for further work on the purification of the target compounds

Modeling the Formation of Polylactide Microspheres

MODELING THE FORMATION OF POLYLACTIDE MICROSPHERES. Biodegradable polylactide microspheres have been developed from a dispersion solution of polylactide in chloroform with polyvinyl alcohol in water. The present paper focuses on developing an understanding of microspheres formation through simple dimensional analysis and principle of system similarity for microstructure observation of microsphere diameter formed. Theoretical correlation between microspheres diameter and agitation rate was derived with the concept of similarity. While the empirical correlation between Weber (We) number and microspheres diameter was derived from dimensional analysis of variables that is useful for prediction of microspheres diameter to support Holmium powder. The empiric equation of the microspheres diameter forming as a function of essential process parameters is: ln (dm/dp) = -4.81 + 0.593 ln We
