Penelitian ini bertujuan untuk mengetahui kualitas reproduksi kambing Jawa Randu dengan estrus postpartum (EPP) abnormal dibandingkan dengan kambing Jawa Randu dengan EPP normal (n = 16 kambing) dilihat dari kadar hormon estrogen dan tampilan estrus. Data yang diperoleh dianalisis secara deskriptif dan secara non parametrik menggunakan Mann Whitney U-test dengan bantuan Statistical Package for the Social Science (SPSS) 16. Hasil analisis deskriptif pada kadar hormon estrogen menunjukkan bahwa EPP normal memiliki kadar yang lebih tinggi (133,8; 141,5; 155,6; 162;25, 167;75 pg/mL) dibandingkan dengan kadar hormon estrogen kambing Jawa Randu EPP abnormal (109,9; 111,35; 101,2; 132,2; 142,45 pg/mL). Hasil analisis Mann Whitney U-test untuk ferning dan kelimpahan lendir serviks menunjukkan tidak terdapat perbedaan antara kambing Jawa Randu EPP normal dibandingkan kambing Jawa Randu EPP abnormal. Jawa Randu dengan EPP normal mempunyai kadar estrogen yang lebih tinggi dibandingkan dengan EPP abnormal. Tetapi, kelimpahan dan lendir serviks antara kedua kelompok kambing tidak berbeda.

This research aims to examine the effect of tax authorities, tax knowledge and taxpayer awareness on taxpayer compliance with financial conditions and taxpayer risk preferences as a moderating variable. The sample in this study is 100 individual taxpayers who conduct business activities and free work in Pekanbaru Distribution of questionnaires is done by proportional sampling method. The questionnaire distributed was 110, but only 100 could be processed with a response rate of 90.9%. The data analysis technique in this research uses the classic assumption test, and Moderated Regression Analysis (MRA) through SPSS 23. The results of the testing of the research hypothesis indicate that of the nine hypotheses in this study, there were only 2 hypotheses that were not proven, namely hypothesis 5, moderated tax knowledge financial conditions have an effect on taxpayer compliance and hypothesis 7, namely tax service providers moderated wp risk preferences affect taxpayer compliance. Meanwhile, 5 more hypotheses have proved to be influential.

Cellulolytic bacteria are a group of bacteria that have an ability to degrade material containing cellulose and have potency to inhibit the growth of pathogenic bacteria. The bacteria can be found in soil or sediment in the mangrove ecosystem. This research aimed to: 1) isolate cellulolylitic bacteria from mangrove sediments in Dumai Marine Station, of Riau, Indonesia, 2) to examine the antagonism against pathogenic bacteria (Escherichia coli, Pesudomonas aeruginosa, Vibrio alginolyticus), and 3) to identify and the phenotype and genetic characters of the potential isolates. The bacteria were isolated on Zobell Marine Agar 2216 added with carboxymethyl cellulose (CMC). Cellulolytic index value was obtained by reducing clear zone diameter with the bacterial colony diameter. Disc diffusion agar method was used to examine antagonism of selected isolates against pathogens. The isolates were observed for the colony and cell morphology, biochemical and genetically characters. Twenty four isolates showed cellulolytic activity and index values ranged from 1.00 to 2.86 and 0.01 to 2.12, respectively. Nine of selected isolates performed ranges of zone inhibition against E. coli, P. aeruginosa and V. alginolyticus from 2.38 ± 0.21 mm to 3.58 ± 0.83 mm, 2.75 ± 0. 59 mm - 4.81 ± 0.57 mm and 2.28 ± 0.45 mm - 4.68 ± 1.40 mm, respectively. Based on the 16S rDNA sequence analysis, three cellulolytic isolates indicated similarity to Bacillus toyonensis (99.53 %).
