Abstract

The many side effects of consuming chemical-based drugs in maintaining human health have led to a tendency to return to nature. Consumption of medicinal plants in fresh or dried form has been considered to minimize side effects. This research will examine the feasibility of cat's claw (Uncaria tomentosa Wild. Ex Schult) tea as a functional drink based on physicochemical parameters and total phenol content. The physicochemical parameters tested included pH, water content, ash content and organoleptic examination of herbal teas including taste, odor and color of the brewed solution, while the total content of phenolic compounds was carried out based on the Folin–Ciocalteu method. Organoleptic examination showed a characteristic odor of the leaves, such as the smell of herbal teas in general with a bland and astringent taste, and the juice of the solution was yellowish green. The results of the physicochemical parameter test showed that the pH of the solution was 6.9, the water content was 7.7, the ash content was 8.00%, while the total phenol content measured was 68.77 mg GAE/g sample.  The physicochemical parameters measured from the testing of cat's claw herbal tea in this study met the quality requirements of dry tea according to SNI No 3836 BSN 2013

Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the horticultural commodities that has high economic value and market demand. Cayenne pepper production in West Kalimantan is low due to soil conditions dominated by peatlands with high acidity and low soil fertility. Resetting soil fertility can be done using liquid organic fertilizers (LOF) such as coconut water waste and pineapple peel. Both types of LOF have nutrient values that are sufficiently beneficial for plants. This study aims to determine the response of cayenne pepper plants to applying both types of liquid organic fertilizer (LOF) alone and the effect of the combination of liquid organic fertilizer of coconut water waste and pineapple peel. This study uses a completely randomized design (CRD) with a factorial pattern consisting of 2 factors, namely coconut water waste and pineapple peel waste liquid organic fertilizer. Each factor consists of 4 treatment levels and is repeated 4 times, namely A (coconut water POC) A0 = 0 ml (control); A1 = 150 ml; A2 = 250 ml; A3 = 350 ml; B (pineapple peel POC) B0 = 0 ml (control); B1 = 50 ml; B2 = 100 ml; B3 = 150 ml. Data were analyzed using the Analysis of Variance (ANOVA) test and continued with the Tukey test at the 5% test level. The results showed that the treatment of  350 mL coconut water POC / 150 mL pineapple peel POC in combination gave a significantly different effect on height, number of branches, flowering time, number of flowers, number of fruits, wet weight and dry weight of plants.

Abstract

The high demand for N95 masks, especially during the COVID (Coronavirus disease)-19 pandemic, has caused shortages worldwide. This study aimed to examine the sterilization ability of the portable sterilizer prototype for N95 masks and its effect on the filtration ability and changes in air resistance on the N95 mask in order to thrift personal protective equipment (PPE) use during a shortage. The sample used was an N95 mask type 1860. The mask was contaminated with 0.6-0.8 MFU Staphylococcus aureus and Escherichia coli. The sterilization methods used were Ultraviolet Germicidal Irradiation (UVGI), Heat at 75°C, and a combination of both from 1 to 120 minutes. Next, the masks were cultured in a nutrient agar medium. For aerosol penetration and air resistance tests, masks were tested before and after the sterilization process, lasting from 5 to 60 minutes. This prototype sterilizer with Heat effectively killed E. coli and S. aureus starting from 3 minutes. The filtration ability of the N95 mask was maintained at >95% even after the sterilization process with 75°C heat, UVC, or a combination of both for up to 60 minutes. There was also no significant difference in air resistance between new masks and masks that had been sterilized using a portable sterilizer. This prototype sterilizer with Heat at 75°C can effectively sterilize against both gram-positive and negative bacteria in the N95 mask without reducing the aerosol filtration ability and changing the air resistance of the N95 mask.
