Abstract

This study aims to determine the effect of the drying method and optimum temperature on the quality of coffee skin tea (cascara). This research was conducted at the Laboratory of Food Processing Technology and Agricultural Products, Department of Agricultural Products Technology, Faculty of Agriculture, Santo Thomas Catholic University, Medan. This research was conducted in March 2023 until completion. This research was conducted using a completely randomized design (CRD), which consisted of 2 factors. The first factor is the drying method (P), namely L : P1 = 4 hours, P2 = 6 hours, P3 = 8 hours and P4 = 10 hours. The second factor is the effect of drying temperature on the quality of tea from coffee skin (T), namely: T1 = 40°C, T2 = 50°C, T3 = 60°C and T4 = 70°C. The results showed that the drying method had a very significant effect (p<0.01) on the yield, water content, polyphenol content, organoleptic value of taste, organoleptic value of aroma and color organoleptic value of cascara tea produced. The longer drying time, the yield and organoleptic value of flavor increase, while the water content, polyphenol content, organoleptic value of aroma and organoleptic value of cascara tea produced decreases. The drying temperature has a very significant effect (p<0.01) on yield, moisture content, polyphenol content, the organoleptic value of taste, the organoleptic value of aroma, and organoleptic value of color. The higher the drying temperature, the higher the yield and taste organoleptic value, while the water content, polyphenol content, aroma organoleptic value and color organoleptic value decreased. The interaction of the drying method and temperature treatment had a significant effect (p<0.015) on the moisture content, polyphenol content, and aroma organoleptic value of cascara tea but had no significant effect (p>0.05) on yield, taste organoleptic value, and color organoleptic value of coffee skin tea (cascara). The best quality of cascara tea was obtained in the treatment combination P1T4.

Abstract. Hernosa SP, Tampubolon SDR, Siregar LAM. 2022. The use of Indole Butyric Acid on the growth of dragon fruit plant stem cuttings. Nusantara Bioscience 14: 211-216. The difficulty of root growth of dragon fruit cuttings is affected by stem rot; one way to increase the growth of cuttings is to use a growth regulator, namely Indole Butyric Acid (IBA), which is used to stimulate the growth of dragon fruit rootstock cuttings. This research was conducted in Sidorukun Village, Pangkatan Sub-district, Labuhan Batu District, North Sumatra, Indonesia, at an altitude of ± 40 m above sea level, from June to October 2020. The research design used was a randomized block design with five treatments. The concentration of the IBA hormone consists of B0 : 0 ppm, B1: 4,500 ppm, B2: 5,500 ppm, B3: 6,500 ppm, B4: 7,500 ppm, and five replicates, so the entire experimental plot was 25. Parameters observed were percentage of shoot emergence, age of shoot emergence, shoot length (cm), shoot fresh weight (g), shoot dry weight (g), root length (cm), fresh root weight (g), root volume (g), and root dry weight (g). Data analysis used a linear model followed by Duncan's test. It is known that the administration of Indole butyric acid (IBA) significantly affected the observed parameters on shoot emergence, age of shoot emergence, number of shoots, root length, fresh root weight, root volume, and root dry weight. However, it did not affect the observed parameters, namely, shoot length, shoot fresh weight and shoot dry weight. On the other hand, B4 concentration (7,500 ppm) gave better shoot growth, root weight, and root dry weight.

Abstract

This research aims to determine the growth response of vetiver, lemongrass and citronella plants in terms most resistant to soil salinity stress levels. The study was carried out at the screen house of the Faculty of Agriculture, Santo Thomas Catholic University, Medan, which is 32 meters above sea level. This research was carried out in January to March 2024. The study used a factorial, Completely Randomized Design, which consisted of two factors. The first factor is the influence of several aromatic grasses (R), which consist of 3 types: lemongrass, citronella, and vetiver. The second factor is the salinity soil stress (S) level, which consists of five levels: without saline, 25% saline soil, 50% saline soil, 75% saline soil saline, and 100% saline soil. Based on these treatment combinations, there were 15 combinations, and each treatment was repeated 3 times so that 45 plants/pots measured 5L. Parameter observations were carried out during harvesting; the parameters observed were shoot fresh weight, shoot dry weight, root fresh weight, root volume, and root cross-section anatomy. The results of the study can be stated that the factor of several aromatic grasses has a significant effect on shoot fresh weight, shoot dry weight, roots fresh weight, and roots volume, where the best aromatic grasses is vetiver even though it was not significantly different from citronella which is resistant to growth at salinity stress levels of 50% to 100%. The salinity level also has a significant effect where salinity starting from 25% causes a decrease in the fresh weight and dry weight of the shoot of the three aromatic grasses.
