Abstract

Upaya induksi persalinan adalah prosedur umum yang digunakan pada praktik kebidanan secara luas di seluruh dunia. Semua kehamilan akan menuju pada suatu keadaan aterm dan proses persalinan akan berlangsung secara spontan. Kenyataannya ada beberapa keadaan yang mengharuskan untuk mempercepat proses persalinan dengan mempertimbangkan keadaan ibu dan janin. Kehamilan postmatur adalah salah satu indikasi dilakukannya induksi persalinan. Meskipun di RSUD Wates sudah ditetapkan protap mengenai induksi persalinan, tetapi penggunaan jenis induksi masih beragam antara misoprostol per oral dan balon kateter dan sampai saat ini belum diperoleh metode induksi yang efektif dalam hal waktu.Tujuan penelitian untuk membandingkan lama pemberian induksi antara misoprostol per oral dan balon kateter pada kehamilan postmatur.

Abstract

Dalam proses industri sering terjadi masalah, salah satunya adalah adanya kebocoran/penipisan pada alat prosesproduksi yang disebabkan oleh korosi. Korosi merupakan proses kerusakan/degradasi pada material akibat berinteraksidengan lingkungan. Salah satu cara pencegahan korosi adalah dengan menambahkan inhibitor. Inhibitor adalah senyawakimia yang dapat mengendalikan atau memperlambat proses korosi. Polifosfat merupakan salah satu inhibitor yang baikuntuk mengendalikan laju korosi. Inhibitor polifosfat dapat mengurangi aktivitas proses korosi dan tidak menyebabkankerusakan pada material dan lingkungan. Penelitian ini bertujuan untuk mengetahui dan mempelajari pengaruh inhibitorpolifosfat dalam mengendalikan korosi pada pipa air, menghitung laju korosi yang terjadi pada bahan logam tanpainhibitor dan memakai inhibitor serta mengetahui jenis logam yang baik dan tahan korosi agar dapat digunakan padaalat proses industri. Penelitian ini dilakukan dengan cara merendam coupon corrosion (besi, stainless steel, danaluminium) selama 1 minggu di dalam larutan NaCl dengan berbagai konsentrasi yang berbeda (500, 5000, 15.000, dan30.000ppm), tanpa inhibitor dan dengan menggunakan inhibitor polifosfat dengan berbagai konsentrasi polifosfat (50,100, 200, 300, dan 400ppm). Hasil dari penelitian ini diperoleh untuk uji tanpa inhibitor bahwa semakin tinggikonsentrasi NaCl maka laju korosi semakin meningkat pada berbagai coupon korosi. Sedangkan untuk uji denganmemakai inhibitor polifosfat, laju korosi menurun sampai pada titik konsentrasi NaCl 300ppm pada berbagai couponkorosi. Laju korosi yang tertinggi diperoleh pada logam besi dibandingkan dengan aluminium dan stainless steel. Lajukorosi yang terendah terjadi pada stainless steel.Kata Kunci : Inhibitor, Inhibitor Polifosfat, Korosi

Abstract

The Study of the solar absorber with cobalt oxide as the heat absorbing surfaces has been conducted. A dip-coating technique has been used to deposit cobalt oxide coatings on aluminum substrates. A solution of cobalt oxide was prepared in a bath by first mixing Co(NO3)2.6H2O, ethanol and a small amount of propionic acid. The sol prekursor was stirred for 2 hours at room temperature. Pieces of aluminum with size 2x4x0.5cm were cleaned using a solution of phosphoric acid 10% at temperature 50oC for 10 minutes. The coating was synthesized by varying molar percursors 0.1M; 0.2M; 0.3M and the number of dipping-drying cycles 2x, 4x, 6x, 8x and 10x, then annealed at temperature 550 oC for 1 hour. The solar absorptance and emittance were parameters to characterize the performance of the absorber. In practical terms, this generally corresponded to absorbing short wavelengths up to a certain cut-off wavelength (solar spectrum, UV-VIS-NIR), and a low thermal emittance in the IR wavelength region. Consequently, this research attained high performance solar selective absorber of which solar absorptance was 80,14% and emittance was 7,65% on 4 cylcles. Values of selectivity, α/ɛ = 10,48 were obtained. XRD test showed the crystal structure of cobalt oxide, SEM test showed the surface structure of the coating was relatively homogenous and adhesion test showed the adhesion between the coating and the substrate can be categorized as very strong (5B scale ASTM D 3359).Keyword : coating, solar selective absorber, sol-gel dip-coating

Abstract

Magnetite is a material that can be used in a drug delivery aplication. The purpose of this study is to determine the effect of temperature and stirring rate on the magnetite crystal size and determine the kinetic equation of magnetite synthesis with Avrami model approach. The magnetite was synthesized using coprecipitation method by reacting FeCl3 and FeCl2 in 2:1 mole ratio and NH4OH 10% at temperature range of 40°C, 60°C, 80°C, and a stirring rate were 300, 400, 500 rpm in a beaker. Samples were taken about 20 mL in every 5 minutes for 30 minutes. Then the sample was filtered to separate solids and filtrate. Analysis of Fe concentrations in the filtrate was using AAS, while the precipitate was washed until neutral and dried at 100°C for 2 hours. Then the magnetite powder was characterized by XRD and SEM-EDX. From the characterization we found a cubic structure of magnetite and crystals size of magnetite is about 10-12 nm formed. The morphology of the magnetite particles tended to be aglomerated but if the temperature and stirring rate increased, the aglomeration of the particles would be uniform. This synthesis of the magnetite could be approximated by the Avrami model with the core of forming function value (n) is ranging from 1.3-1.6. If the temperature and the stirring rate increased, the value of the rate constant of transformation (k) increased too. At temperature 30 °C; 300 rpm obtained the constant rate of transformation of 0.01 min-1 and 0.08 min-1 at temperature 80 °C; 500 rpm.Keywords: aglomeration, avrami, coprecipitation, drug delivery, magnetite
