Calcium Oxide (CaO) yang diembankan pada zeolit dikategorikan sebagai katalis heterogen. Penggunaan katalis CaO dapat digunakan dalam proses pirolisis katalitik guna meningkatkan produksi gas. Dalam penulisan ini, CaSO4.2H2O merupakan sisi aktif yang diembankan pada zeolit alam dan aktivitas dari katalis CaO-Zeolit disintesis dengan impregnasi sonokimia yang dibantu dengan proses pengeringan da…
Sintesis senyawa poliol sebagai bahan intermediate pada pembuatan pelumas dari minyak kelapa sawit (CPO) telah dilakukan untuk mensubstitusi pelumas dari minyak bumi. Penelitian ini bertujuan untuk mengetahui pengaruh suhu, waktu reaksi dan katalis terhadap konversi senyawa poliol yang dihasilkan dengan variabel suhu 45, 50, 55, dan 60 °C dan waktu reaksi 30, 60, 90, 120 menit serta katalis Be…
Background: Blood sugar test must be done to make the diagnosis of diabetes mellitus. Sometimes, blood sugar tests are considered less deseribes the situation of the patient's blood sugar. For that, a better another test is required, ie HbAlc test. There have been many studies which claimed there was a strong correlation between the value of HbAlc and fasting blood sugar levels. However, the de…

This research focuses on the synthesis of single layer Fe2O3 and Fe2O3/ZnO hybrid layers using the spray pyrolysis method with the aim of conducting photoelectrochemical studies on samples that have been synthesized with volume variations of 10 and 30 mL in each layer variation (Fe2O3, Fe2O3/ZnO, ZnO/Fe2O3) which was annealed at 500˚C. Photoelectrochemical studies using the LSV method showed t…
Seiring dengan meningkatnya tuntutan terhadap bahan-bahan yang ramah lingkungan dan biodegradable serta renewable, sehingga selain dari fungsinya, ada usaha untuk menggantikan pelumas non biodegradable yaitu pelumas bio (Biolubricant). Saat ini, pelumas berbahan dasar minyak nabati (Biolubricant) semakin banyak digunakan dalam industri pelumas untuk menggantikan pelumas berbasis minyak bumi kar…
The research on the adsorption of the procion red mx-5b dye using the CaO/Fe3O4 composite has been carried out. CaO/Fe3O4 composite with mass ratio (1:1) were synthesized using coprecipitation method. Material characterization using XRD, BET, VSM and FTIR. The results of XRD characterization of the CaO/Fe3O4 composite showed the presence CaO at the diffraction peak at 2θ = 53.66o and Fe3O4 at …
Introduction : Regional anaesthesia is the mostly used technique for caesarean section. One of the most preferred technique is spinal anesthesia because it has some advantages such as rapid administration and onset of anesthesia, the simplicity of technique, and a steady block, but on the other hand it often cause complications including hemodynamic changes, which are increase of heart rate, de…
Diabetes melitus ( DM) can attack all the human body System and generates assorted of sigh, including sigh in oral cavity. The oral manifestation of DM patient is xerostomia, caused existence of angiopathy, neurophathy and dehydration as diuresis osmotic. Xerostomia is not the only oral manifestation in DM, because degradation of stream saliva vvill have an effect on also at oral cavity defence…

Research aims to find out the influence of education about diet management through video media and booklets on the level of knowledge of member…
Background : Type 2 Diabetes mellitus is a chronic disease which is classified by the increase in blood glucose level. WHO predicted in 2004 more than 200 million people diagnose type 2 Diabetes mellitus. Indonesia is the fourth country that has a largest number of people with type 2 Diabetes mellitus, which is about 8 million people. For this reason research is needed on rational of oral hypog…
