Csr Strategy

The objectives of this study were to examine whether (1) the students’ achievement on reading comprehension taught by using CSR Strategy is higher than that of taught by using REAP Strategy, (2) reading comprehension achievement of reflective cognitive style is higher than reading comprehension achievement of impulsive cognitive style, and (3) there is interaction between teaching strategies and cognitive styles on students’ achievement on reading comprehension. This study was conducted by using experimental research with factorial design 2X2. The data were analyzed by using Two-Way ANOVA. Based on the analysis, there were found that (1) CSR and REAP strategy significantly affect students’ achievement on reading comprehension, students’ achievement on reading comprehension taught by using CSR is higher than that of the students’ taught by using REAP; (2)the achievement on reading comprehension of the students with reflective cognitive style is higher than that of the students with impulsive cognitive style; and (3) there is an interaction between teaching strategies and cognitive style on students’ reading comprehension achievement. It showed that students who read with reflective cognitive style got higher result than students who read with impulsive cognitive style if they were taught by CSR, and students who read with reflective cognitive style got higher  result than students who read with impulsive reflective style if they were taught by REAP. Key words: cognitive style; reading comprehension; and teaching strategies

The main aim of the present work was to develop the microcapsules of tramadol hydrochloride for the oral sustained release drug delivery. Tramadol hydrochloride a BCS class I drug a centrally acting synthetic analgesic was complexed with Indion 254 ion exchange resin. The microcapsules were prepared by encapsulating the prepared resinates by o/o solvent evaporation technique. In the investigation 32 full factorial design was used to investigate the joint influence of two formulation variable amount of eudragit RS 100 and plasticized PEG 400. The results of multiple linear regression analysis indicated that for obtaining a sustained release drug delivery the optimum concentrations of both the plasticizer and coating solution to be used. The factorial models were used to prepare optimized microcapsules and optimized formulations showed sustained release profiles for the extended period of more than 12 hrs. From the present investigations concluded that resinate microcapsules of highly water soluble drug can provide controlled release of drug for extended period.Key Words: Tramadol hydrochloride, ion exchange resinate, microcapsules, sustained release

<p class="JurnalASSETSABSTRAK">ABSTRAK</p><p>Pengampunan pajak telah dilakukan berulang kali di Indonesia yaitu 1964, 1989, 2008 dan 2016. Penelitian ini menguji apakah ada perbedaan kepatuhan pajak antara yang mengetahui pengampunan pajak berulang serta merasakan kepastian penegakan hukum dan yang tidak. Penelitian ini menggunakan  quasi eksperimen faktorial 2 x 2 antarsubyek dengan mahasiswa akuntansi di FEB yang sedang mengambil matakuliah manajemen pajak sebagai partisipan. Hasil dari penelitian ini adalah terdapat pengaruh antara pengetahuan tentang pengampunan pajak berulang maupun kepastian penegakan hukum terhadap kepatuhan pajak. Hasil dari pengujian interaksi yang diperoleh adalah ketika wajib pajak tidak mengetahui adanya pengampunan pajak yang berulang dan merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang paling tinggi. Sebaliknya ketika wajib pajak mengetahui adanya pengampunan pajak yang berulang dan tidak merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang rendah.<em></em></p><p class="JurnalASSETSABSTRAK"><em>ABSTRACT</em></p><p><em>Tax amnesty has been repeadly implemented in Indonesia namely 1964,1989, 2008 and 2016.The purpose of the study is to examine is there any tax compliance differences between those who perceive recurring tax amnesty and feel legal certainty and to those who do not. This quasi experiment design was consisted of 2x2 between subject factorial design, with Bachelor’s Degree of Accountancy at FEB UKSW who took Taxation Management as participants. The result shown that there is influence between recurring tax amnesty knowledge and legal certainty in the tax compliance. The result of the interaction testing shown that when taxpayer are not aware of any recurring tax amnesty and feel the high legal certainty will result high compliance. Conversely, when taxpayers know that there is recurring tax amnesty and do not sense a high level certainty, it would result a low tax compliance.<br /></em></p>

The objective of this research is to know the optimal formula of Indole Butiric Acid (IBA), Naphthalene Acetic Acid (NAA), Vitamine B1 and the combination with shading intensities to the acclimatization of Gaharu stump (Aquilaria beccariana). This research used Factorial Design with basic analysis of Complete Randomized Design in order to know theeffect of treatment. The research was carried out in Agroindustry and Biotechnology Laboratory, Ciampea, Bogor, from July to September 2007. The results of the research showed that after 8 weeks of treatment: (a). The combination of 55 % shading intensity with IBA 15 mg/l + NAA 10 mg/l + Vitamine B1 1 mg/l was the best formula for increasingheight of Gaharu stump 4.660 cm. (b). The combination of 55 % shading intensity with IBA 15 mg/l + NAA 30 mg/l + Vitamine B1 1 mg/l was the best formula for increasing sum of Gaharu leaf stump 12.337 leafs, (c). The combination of 55 % shading intensity with IBA 15 mg/l + NAA 40 mg/l + Vitamine B1 1 mg/l was the best formula for increasing sumof Gaharu root stump 3.783 roots, and (d). The combination of 55 % shading intensity with IBA 15 mg/l + NAA 40 mg/l + Vitamine B1 1 mg/l was the best formula for increasing length of Gaharu root stump 3.686 cm.
