The students learning process is necessary in learning and teaching process because the result of the lesson determined by the process that the students got.Recording to this, the researcher was interested in conducting a study about the improvement of the students motivation in learning by using inquiry approach in physic at grade XI MULTIMEDIA term one SMKN 1 Gunung Talang. The method used in this study was decriptive with percent data analysis technique. The results of the study informed: [1].The using of inquiry approach in physic learning could increase students, [2].The motivation implementation and their grade of inquiry approach is one of the solution to overcome to the the low students motivation in learning.

Peresepan puyer untuk anak masih banyak dilakukan dikarenakan kemudahan pemberian dan pengaturan dosis. Pembuatan puyer di apotek pada proses pembuatannya hanya berdasarkan pada visual baik dalam pencampuran maupun pembagian kedalam bungkus puyer, hal ini dapat menyebakan heterogenitas bobot antara puyer yang satu dengan yang lainnya dan menyebabkan pemberian dosis yang tidak sama. Penelitian ini bertujuan untuk melihat dan menggambarkan mutu sediaan racikan puyer dari segi keragaman bobot dan keseragaman kadar. Evaluasi keragaman bobot dilakukan berdasarkan prosedur uji keragaman bobot kapsul keras yang tertera pada Farmakope Indonesia V menggunakan imbangan analitik dan uji keseragaman kadar dilakukan menggunakan Spektrofotometri UV-Vis. Hasil evaluasi keragaman bobot menunjukan tidak ada sampel yang memenuhi syarat keragaman bobot serta, tidak ada sampel yang memenuhi persyaratan keseragaman kadar menurut Farmakope Indonesia V.

Peracikan obat merupakan salah satu dari bentuk pelayanan kefarmasian yang menjadi tanggung jawab seorang apoteker di apotek dan sarana pelayanan kefarmasian lainnya. Proses peracikan yang baik akan menghasilkan sediaan yang bermutu, aman dan efektif. Sediaan obat termasuk sediaan hasil peracikan harus terjamin mutu dan keamanannya. Di Indonesia khususnya belum terdapat prosedur dan standar mutu sediaan racikan.Penelitian ini bertujuan melakukan evaluasi mutu puyer hasil racikan apotek di kecamatan Ciputat yaitu keseragaman sediaan. Sediaan puyer disampling dari semua apotek (8 apotek) yang terdapat di wilayah kecamatan Ciputat Timur. Analisa yang dilakukan adalah keragaman bobot dan keseragaman kandungan. Penetapan keragaman bobot dilakukan menggunakan timbangan analitik dan keseragaman kandungan menggunakan Spektrofotometer UV-Vis. Hasil dari penelitian ini menunjukkan bahwa, sediaan racikan puyer dari 8 apotek di kecamatan Ciputat Timur tidak memenuhi uji keragamanan bobot dan keseragaman kandungan menurut Farmakope Indonesia V.

Ethyl p-methoxycinnamate (1) is the main secondary metabolite found in Kaempferia galanga Linn and has various interesting pharmacological activities, including anti-inflammatory, sedative, vasorelaxant, and antiangiogenic activities. This study aimed to optimize the conditions for the conversion of 1 to 4-methoxychalcone (2) using a conventional synthetic reaction. The conversion was initiated by the hydrolysis of 1 to p-methoxycinnamic acid (3) and 3 to 4-methoxybenzaldehyde (4), and continued with the Claisen-Schmidt reaction of 4 with acetophenone (5). The temperature (room temperature and 45 °C) and ratio of 4 to 5 (1:1 and 1:2) were varied to determine the optimal conditions for the reaction. The results suggested that the reaction of 4 with 5 gave the best yield (42.1 %) when conducted at room temperature in a ratio of 4 to 5 (1:1). The structure of the reaction product was elucidated by spectroscopic analysis and compared with previously published data
