Abstract

The kaolin detergent preparation as an alternative a dog saliva cleanser has been carried out by varying the concentration of Methyl Ester Sulfonate (MES) surfactant. This study aims to obtain the best kaolin detergent composition based on the results of physicochemical testing. The manufacture of kaolin detergent in this study has three stages. The first step is the preparation and characterization of kaolin using X-Ray Diffraction (XRD). The second step is the manufacture of kaolin detergent with various concentrations of MES surfactant by 10%, 14%, and 18% (w/w). The third step is testing the physicochemical properties which include organoleptic, pH, foam stability, and surface tension. The results showed that kaolin used in the manufacture of detergents has the main mineral content in the form of kaolinite is shown at 2θ=12,24o (d=7,24 Å) and 2θ=24,78o (d=3,58 Å). Based on the results of physicochemical testing, kaolin detergent F3 (MES 18%) was chosen as the best kaolin detergent because it has a thick and homogeneous liquid form, soft texture, white color, has a coconut milk smell, pH 8,270, and surface tension of 0,010 Nm-1.

Abstract

Rice (Oryza sativa L.) is the most nutritious staple food for most Indonesian people. The Ministry of Agriculture through the Agricultural Research and Development Agency has released about 300 rice varieties. Some of these varieties have advantages that are beneficial for health. The purpose of this article was to review literature describing the specialty rice varieties from Indonesia, with a particular focus on low Glycemic Index, high antioxidant and high mineral content. Low GI rice is one way of coping with diabetes mellitus (DM). Hyperlipidemia, diabetic syndrome, and cancer diseases could be prevented by consuming pigmented rice which is rich in antioxidants. Fortified rice could be used to overcome iron nutritional anemia and stunting problems. In order to to overcome nutritional and health problems in Indonesia, it is hoped that specialty rice could be used as a complementary program in the food diversification program that has been developed by the government. Specialty rice available in the market still has to pay attention to the quality class of the rice. Socialization about specialty rice needs to be conducted, and the availability of specialty rice opens up export opportunities.

Abstract

Flavonoid compound was isolated from Crinum amabile Donn. leaves. The separation of flavonoids was carried out by using chromatographic techniques to purify CH2Cl2 extract of Crinum amabile Donn. leaves. Column chromatography with silica gel and sephadex as stationary phases, thin-layer chromatography, and preparative thin-layer chromatography were the chromatographic techniques used in this research. The pure compound obtained in the form of white-yellow solid with the Rf value is 0.44. Compound identification using 1H-NMR spectrometer showed the presence of protons from the CH=CH ortho with the appearance of a doublet of doublet (dd) each having j values of 8.5 Hz and 8.1 Hz with chemical shifts in the range of 6.5 ppm and 7 ppm. The CH=CH ortho group with the appearance of doublet of doublet of doublet (ddd) each having j values 8.4 Hz and 9 Hz with chemical shifts in the range of 7.2 ppm to 7.4 ppm. The methoxy group (-OCH3) was detected on chemical shift 3.8 ppm. Spectrometries of analysis showed that flavonoid compound obtained was 4-Hydroxy-7-Methoxyflavan.

Abstract

Learning in the online era is not a barrier for tutoring institutions in providing online services. However, from the user's perspective, there is an inhibiting factor, namely decreased learning motivation when using online learning platforms. One of the aspects is usability and instructional design. In particular, students' approaches to learning through online tutoring systems were examined. Students from various types of education participate in this course namely junior high students, high school students, vocational high school students, universities and the general public. Using a qualitative research approach that examines data from the perspective of student experience. The study found that the completeness and clarity of instructional design had a dominant factor in influencing students' learning motivation. While the usability aspect is not significant enough in influencing the learning motivation of tutoring
