Abstract

Background: Problems that arise in students based on the results of the 2016 study indicate that more than 80% of students like to eat unhealthy snacks such as packaging snacks, fried foods, instant noodles, and meatballs. Where snacks contain high energy, carbohydrates, protein, saturated fat, and salt. The excess energy and nutrients intake are related to increasing the metabolic incidence of syndromes and the main risk factors for cardiovascular disease.Objectives: This study aims to determine the effectiveness of giving nutritional interventions to eating habits and anthropometric status of college students in Malang.Methods: The quasi-experimental design with 31 participants from college students in Malang. Nutrition interventions provided in the form of education related to healthy snacks and assistance in making healthy snacks. The instruments used were pretest-posttest, questionnaire, and semi FFQ. Data processing was carried out by descriptive statistical analysis and dependent t-test at a 95% confidence level.Results: There was a significant increase in knowledge related to healthy snacks for subyek penelitiants (p <0.01) indicated by the results of the pre-test and post-test. There was an increase in the influence with nutrition claims by 31% and there was a significant difference between before and after the intervention (p = 0.013). The results of a healthy semi FFQ snack for the fruit category experienced a significant increase after being given an intervention program (p <0.01), while the semi FFQ results for unhealthy snacks for the category of salted crackers, chocolate/candy, pudding, and market snacks tended to decrease in consumption although not significant. The prevalence of overweight and obese in participants before being given intervention was 29% and decreased after being given intervention to 22.6% even though there was no significant difference (p = 0.096).Conclusions: There is an increase in the influence of 'nutrition claims' and fruit consumption significantly. While the prevalence of obese tends to fall even though it is not significant between college students.

Abstract

Blusher is a decorative cosmetic whose purpose is to beautify the face and emphasize the shape of the cheekbones. Rhodamine B is a synthetic dye in the form of a crystalline powder which is prohibited from being used in cosmetics according to the regulation by Head of The Indonesian Food and Drug Administration No. 18 of 2015 concerning Technical Requirements for Cosmetic Materials, because they are dangerous if contact with the skin. The purpose of this study was to determine rhodamine B in blusher which is traded in Kandat Market, Kediri Regency. In this study, five samples were used, namely sample A, sample B, sample C, sample D, and sample E. The qualitative analysis method used was Thin Layer Chromatography (TLC). In this method, the eluent N-butanol:ethyl acetate:ammonia is used in the ratio (55: 20: 25). TLC results showed visually in pink color, then when viewed under UV light 254 nm was yellow fluorescence. From the five samples, the Rf value was 0.52; 0.56; 0.61; 0.52 and 0.57, while the average Rf of the standard solution of rhodamine was 2.1. So that from the five samples it can be seen that they do not contain rhodamine B dye.

Abstract

Pemanfaatan ekstrak bahan alam dalam biosintesis nanopartikel berkaitan dengan kandungan senyawa metabolit sekunder yang memiliki aktifitas antioksidan. Salah satu tanaman yang mengandung banyak antioksidan adalah sirsak (Annona muricata Linn). Sirsak merupakan tumbuhan yang memiliki banyak manfaat baik dari batang, kulit batang, daun maupun buahnya. Banyak penelitian telah melakukan pemanfaatan dari bagian-bagian dari tumbuhan sirsak. Tetapi belum banyak yang melakukan penelitian pada kulit buah sirsak. Seperti halnya buah manggis baik buah dan kulitnya ternyata memiliki kandungan antioksidan yang cukup tinggi. Antioksidan berasal dari senyawa metabolit sekunder yang ada di tanaman. Keberadaan metabolit sekunder ini dapat diambil dengan cara ekstraksi menggunakan pelarut yang sesuai dengan kepolaran senyawa yang akan diekstrak. Pada penelitian ini digunakan pelarut etanol dan campuran etanol:aquadest . Hasil yang didapatkan rata-rata rendemen menggunakan pelarut etanol:aquadest lebih tinggi (11,64%) dibandingkan menggunakan etanol saja (9,64%). Ekstrak yang didapatkan kemudian dilakukan uji fitokimia secara kualitatif dan didapatkan hasil adanya triterpenoid, saponin, polifenol dan tanin pada ekstrak yang didapat.

Abstract

Cumin leaf are medicinal plants that are used as treatment and useful for health. Cumin leaf contain secondary metabolites, one of which is flavonoids. Flavonoids are the largest phenolic compounds found in plants and function as antioxidant, antibacterial, antiviral, anti-inflammatory, antiallergic, and anticancer activities. The flavonoid content of a plant can be affected by the drying temperature in the manufacture of simplicia. The purpose of this study was to determine the total flavonoid content in cumin leaf if dried by several drying methods. In this study, cumin leaf simplicia was used with different drying methods, namely sun drying, wind drying, and oven drying. The simplicia powder was extracted using ethanol and then tested quantitatively using a UV-Visible Spectrophotometer at a wavelength of 440 nm. Total flavonoid content by sun drying, oven drying, and wind drying was 3,38 mg QE/g extract, 3,58 mg QE/g extract, and 5,83 mg QE/g extract respectively. Based on the research on the flavonoid test on cumin leaves with different drying methods, the lowest average total flavonoid content was obtained on Sun drying was 3.38 mg QE/g extract and the highest was wind drying with 5.83 mg QE/g extract while oven drying was 3.58 mg QE/g extract.

Abstract

Soursop peel can be used as a bioreductor in the green synthesis process of silver nanoparticle formation. This is because the content of secondary metabolite compounds in soursop peel can reduce Ag3+ to Ag0 in nano size. Secondary metabolites in soursop peel are obtained by extraction using a solvent whose polarity value is close to the polarity value of soursop peel secondary metabolites. In this study, ethanol-aquadest and ethanol solvents were used. The extract obtained was then formulated with AgNO3 solution with a concentration variation of 0.5; 1; 1.5 and 2 mM to determine the optimum concentration on the formation of silver nanoparticles. The maximum concentration was obtained at a concentration of 2 mM AgNO3, seen from the highest absorbance obtained at the maximum wavelength observation of 400-450 nm with the concentration of AgNO3 used 2 mM. The silver nanoparticles formed were then analysed using a Particle Size Analyzer (PSA) to determine the size of the nanoparticles formed. Nanoparticles using ethanol-aquadest solvent had a size of 92.83 nm, while those using ethanol solvent had a size of 301.3 nm.
