Profil Pelarutan Granulat Teofilina Dengan Berbagai Macam Kadar Etil Selulosa Sebagai Bahan Pengikat

Profil Pelarutan Granulat Teofilina Dengan Berbagai Macam Kadar 5,0 ± 1 jam) pada pemberian per oral, dibandingkan dengan subyek negara lain. Hal ini berarti subyek Indonesia membutuhkan dosis teofilina yang lebih sering. Pemberian do-sis yang lebih sering kurang menyenangkan serta menyebabkan ketidakpatuhan bagi pasien. Oleh karena itu perlu ki-ranya diberikan sediaan teofina dalam bentuk lepas lambat untuk melepaskan obat aktifnya dalam kurun waktu dan kadar plasma yang dikehendaki, sehingga lama kerja terapetiknya dapat ditingkatkan. Berdasarkan masalah ini maka dicoba untuk membuat rancangan bentuk sediaan lepas lambat dari granulat teofi-lina, yang pembuatannya berprinsip pada pembentukan rintangan fisika yakni perlekatan (embedding). Material ambedding yang berbeda-beda diharapkan mempunyai waktu disolusi yang berbeda-beda pula. Etil selulosa yang bersifat hidrofob digunakan sebagai pengikat yang dapat memperlambat pelepasan obatnya, dikombinasi dengan metil selulosa yang bersifat hidrofil untuk memperoleh kerja sama yang baik dalam melepaskan obatnya. ..

Study of chromium removal from wastewater using SSF-CW model: comparison between physical adsorption by coal CFA and phytoremediation by vetiver grass (Vetiveria Zizanioides L)

The study aims to compare the effectiveness of chromium removal from water using adsorption by coal fly ash (CFA) and phytoremediation by vetiver grass (Vetiveria zizanioides L) as well as a combination of both CFA and vetiver grass. The experiment was carried out in four different reactors, having size of 100 cm (length) x 60 cm (wide) x 80 cm (height). One reactor was filled with gravel and CFA, without vetiver grass (RI), while another one was filled with gravel and vetiver grass, without CFA (RIV). The other two reactors were filled with gravel, CFA, and vetiver grass with the mass ratio of gravel/CFA of (25:2) and (25:1), denoted as RII and RIII, respectively. Fifty (50) L of synthetic wastewater containing 14.612 ppm of chromium was filled into the reactors and continuously recirculated for 15 days. Chromium accumulation in CFA and plants was analyzed on day 15. The results of plant development are indicated by the presence of new shoots and roots that grow during phytoremediation processes. In addition, there was an increase in weight and number of vetiver stems indicating the persistency of vetiver grass in such a harsh wastewater condition. The removal of Cr from wastewater in RI, RII, RIII and RIV at days 15 were 81%, 93.2%, 85.8% and 75.7%, respectively. It can be concluded that: (1) vetiver grass (Vetiveria zizanioides L) has high potential as phytoremediator plant, (2) Chromium adsorption by CFA plays important role in Cr removal from wastewater, and (3) combination of adsorption by CFA and a phytoremediation by vetiver grass significantly increases the removal of chromium from wastewater

PENERAPAN STATISTICS PROCESS CONTROL DALAM PENGAMATAN SIFAT FISIKA DAN KIMIA AIR BUANGAN DARI AIR CONDITIONING (AC)

Statistics Process Control (SPC) is a tool used for on-line quality control in mass production. Control Charts or control charts are selected from statistical sampling theory that is effectively applied in SPC. This paper will explain the function and method of applying one of the tools in SPC to observe the physical and chemical properties of wastewater from air conditioner (AC). The physical and chemical properties observed were TDS, pH, DHL, temperature, and turbidity. The results of the application of SPC by using the control chart shows that the control chart makes it easy for the observer to do the analysis process of the observation data. The results obtained can be taken from SPC on the observation of the physical and chemical properties of AC waste water in the Environmental Laboratory of the Faculty of Biology, Jenderal Soedirman University, namely the average value of each parameter, namely TDS = (4.85 mg / L), pH = 6.53, DHL = 0.00117 (ms), temperature = 23.3C, Turbidity = 0.4265 (NTU). Referring to the requirements of distilled water, the AC waste water is still suitable for use as a substitute for distilled water. The ploting of data on the Xbar-chart TDS data, pH, and Turbidity is within the control limit with a confidence level of 99%, while the Temperature and DHL data are within the control limit with a 95% confidence level. While the results of plotting the data on the Rbar-chart of TDS, DHL, and Temperature data are within the control limits with a 99% confidence level, while the pH and Turbidity data are within the control limits with a 95% confidence level
