Abstract

Brassica oleracea includes vegetables that are consumed as raw vegetables. The habit of eating raw vegetables in the form of fresh vegetables needs to be observed, especially if the method of washing them is not good so that there are still nematode eggs in the cabbage. This study aims to determine the type of intestinal nematode parasites found in raw cabbage sold at the MMTC market and at food stalls in Lau Dendang, Percut Sei Tuan District. This research method uses the Univariate Analysis method where the data that has been obtained is easy to simplify. Then the data can be made in tabular form according to laboratory standards. The results showed that there was contamination by intestinal nematode parasites based on the type of sampling location, namely at the MMTC market and at the food stalls in Lau Dendang. In the MMTC market, there were 5 positive samples (33%) containing hookworm larvae (Ancylostoma and Necator) on cabbage and 10 negative samples (66%) on cabbage. Meanwhile, at the food stall in Lau Dendang, there were 2 positive samples (13%) and 13 negative samples (86%) containing hookworm larvae (Ancylostoma and Necator) in cabbage which is a raw vegetable.

Abstract

Corn, rice, and sugarcane are included in the Poaceae family which have high economic value as staple foods. Nitrate reductase plays a role in reducing nitrate to ammonia. The nitrate reductase activity testing can help biotechnology studies, in this case, fertilizer production or organic waste treatment, because the nitrate reductase enzyme can be used to convert nitrate into more useful nitrogen compounds. The purpose of this study was to analyze the activity of nitrate reductase (ANR) from the leaves of the Poaceae family, namely corn, rice, and sugarcane. In vivo ANR measurements were carried out using the spectrophotometric method with two types of spectrophotometers, namely the Vis/UV Spectrophotometer, Genesys10UV, and Visible Spectrophotometer, with a wavelength of 540 nm. This study concludes that rice had the highest ANR of 0.1503 µmol/gram leaf weight/hour of incubation. The increase in nitrate reductase activity indicates that the energy for nitrate reduction also increases and provides a large capacity for synthesizing amino acids, proteins, or total N assimilation.

Abstract

Pandan Wangi (Pandanus amaryllifolius) is a plant that grows in the tropics and is known to contain antioxidants. Pandan Wangi can be a garden plant or deliberately planted in the yard. The preparations made in this study were pandan extract peel-off gel masks with varying concentrations of polyvinyl alcohol (PVA). PVA is a water-soluble eco-friendly polymer. This study aims to determine the effect of PVA concentration on the physical quality of peel off gel mask preparations of fragrant pandan leaf extract. The research was conducted using laboratory experimental methods. Three gel peel off mask preparation formulas were used in the study, namely FI (5% PVA), FII (10% PVA) and FIII (15% PVA). Parameters for observing the quality of the peel off gel mask preparations included organoleptic tests, namely changes in aroma, color and shape as well as viscosity. The results showed that after a storage period of 28 days, the physical quality of the pandan leaf extract peel-off gel mask was still good. The mask preparation is characterized by a pale yellow color, smells of fragrant pandan extract and has a soft texture. Variation of PVA concentration affected the viscosity of the pandan leaf extract gel mask preparation.

Abstract

Orangutans are the only great apes that inhabit Sumatra and Borneo, but the Bornean orangutan (Pongo pygmaeus) is critically endangered due to health-related issues. Orangutans in zoos or captivity face a higher risk of parasitic infections compared to those in their natural habitats. This is attributed to the unsuitable environmental conditions, such as confined enclosures that restrict their movements and daily activities. Conservation efforts are crucial to prevent orangutan extinction, including ex-situ conservation at Medan Zoo. However, ex-situ conservation also poses the risk of infection by soil-transmitted helminths, nematodes that require soil to reach their infective stage. This research aims to identify the species of soil-transmitted helminths (STH) in Bornean orangutan fecal samples and assess the level of infection. The research method involves descriptive analysis and fecal examination using the native method with six fecal samples from two orangutan individuals. The results revealed the presence of three types of soil-transmitted helminth eggs in both orangutans: Ascaris lumbricoides, Trichuris trichiura, and Necator americanus. The infection level falls into the moderate category (500-5000 eggs).
