PENGOLAHAN BUAH TERUNG POKAK (Solanum torvum) MENJADI TEH HERBAL SEBAGAI MINUMAN FUNGSIONAL

Pokak growing in fertile highlands is still classified as a wild plant and contains good bioactive and nutritional compounds. Drinks made from pokak are potential health drinks. The problem of pokak is relatively little consumed by the people of Indonesia. The results of the pokak research indicate that there are polyphenol compounds, tannins, flavonoids, caffeine, fumaric acid, maleic acid, alkaloids, carbohydrates, proteins, fats, vitamins, minerals. The aims of this research to process pokak eggplant fruit into 2 types of herbal teas, namely black tea and pokak green tea. The observation parameters were the organoleptic test, chemical component test including bioactive compounds and nutrients. The research method used the Fridman test, phytochemical screening, proximate test, Vitamin C, and minerals. The best organoleptic test results include aroma, taste, color, the most preferred by consumers is code 862 TB, namely pokak black tea. Qualitatively, pokak black tea contains saponins, glucosides, steroids, alkaloids. The nutritional test contains carbohydrates, fat, protein, ash content, moisture content, vitamin C. contains minerals Ca, Mg, Fe. The results of the study prove that Pokak herbal tea has a function for health and is potential as a functional drink

AKTIVITAS ANTIOKSIDAN EKTRAK METANOL DAN AIR TEH HERBAL POKAK ( Solanum torvum ) TERHADAP ANTIBAKTERI PATOGEN

Pokak (Solanum torvum) can thrive in Indonesia and had high phytochemical and antioxidant compounds. The aim of this study was to analyze the effect of antioxidant compounds on herbal tea products, namely methanol extract of pokak herbal tea and water extract of pokak herbal tea on the inhibition of the growth of pathogenic bacteria. The herbal tea processing method uses surface response. The measured parameters were the total phenol content, tannins, flavonoids, and antioxidant activity (% DPPH Imbibition) and test for pathogenic bacteria inhibition zone using the disc method. The results showed that the best treatment was pokak green tea water extract containing 93.81% antioxidant activity (% DPPH inhibition), total phenol 55.20 mgGAE/g, tannin content 1.70 mgTAE/g, flavonoid levels 1.78 mgQAE/g. Analysis of pokak green tea water extract at a concentration of 100% had an inhibitory power against pathogenic bacteria E coli 20 mm, 20 mm MRSA, 20 ml Salmonella typhi, 19 mm Streptococcus pneumonia. Pokak green tea water extract can be used as a drink that functions for health in inhibiting the growth of pathogenic bacteria

PENGARUH LOKASI TUMBUH TERHADAP SENYAWA FITOKIMIA PADA BUAH, BIJI, DAUN, KULIT BUAH TANAMAN TAKOKAK (Solanum torvum)

Takokak was a plant that was widespread in Indonesia and quite a lot is made culinary at this time. Research on takokak eggplant was developed due to the high content of phytochemical compounds. The problem that exists was that this plant had not been planted by many people but grows by itself in various locations. The purpose of this study was to know the content of phytochemical compounds in the fruit, seeds, and leaves of takokak that grow and develop in different locations. The experimental design used quantitative tests including antioxidant activity, total phenol, tannin content, flavonoids. The locations studied are at Mojokerto and Malang city. The research resulted show that there were differences in phytochemical content, the best data was eggplant takokak originating in the city of Batu, East Java. The Takokak eggplant plant thrives and had higher levels of bioactive/phytochemical compounds in the sub-tropical climate highlands near the mountains of Batu, Malang

EFEK JENIS MULSA DAN MACAM PUPUK TERHADAP PERTUMBUHAN DAN PRODUKSI KACANG PANJANG (VIGNA SINENSIS .L) VARIETAS PERSADA-355

The research aimed to study the interaction between the effects of various types of mulch and fertilizers on the growth and production of long beans. The research used a randomized block design, Factor I type of mulch consisting of 3 levels: M0 = No mulch, M1 = black and silver plastic mulch, and M2 = Straw mulch. Factor II is the type of fertilizer: including P1 = NPK Mutiara 600 kg/ha, P2 = biological Petrobio 90 kg/ha, P3 = NPK Mutiara 50% + biological Petrobio 50%. The results showed the effects of various types of mulch and fertilizers have significant interaction between the growth of leaf number and fruit weight of long beans, namely M1P3 (black silver mulch and application of 50% pearl fertilizer and 50% biological Petrobio)

Antioxidant activity assay of Roselle (Hibiscus sabdariffa) seeds Ethanol extract with DPPH radical scavenging using UV-Vis Spectrophotometer

Hibiscus sabdariffa (Roselle) is known to have a strong antioxidant compound. Thus, the calyx becomes the most important area to research. Another part of this plant that was starting to be known for its benefits is rosella seeds. Roselle seeds are a source of fat-soluble antioxidants. The aim of this study was to investigate the antioxidant activity of Roselle Seed Ethanol Extract (RSEE) with the DPPH (1,1-Diphenyl-2 Picrylhidrazyl) radical scavenging method. This research begins by doing the extraction of Roselle seeds using ethanol (96%) as a solvent and then assessing the antioxidant activity (Radical Scavenging Activity/RSA) of the extract, which is compared with the ascorbic acid standard at several concentrations (5-200 ppm). Antioxidant activity was assessed with DPPH Radical Scavenging using UV-Vis spectrophotometer and IC50 value parameters. The results of this study were the absorbance of DPPH from spectrophotometer at 517 nm was 0,824 (purple color). The absorbance of RSEE and ascorbic acid at 5 ppm to 200 ppm, respectively 0.523-0.124 and 0.594-0.112. The antioxidant activity (RSA) of the RSEE and ascorbic acid, respectively was  57.93% and 59.24%. The IC50 value of RSEE was 30.158 μg/ml and as comparison is ascorbic acid, the IC50 value was 26.948 μg/ml. Thus, the antioxidant activity of roselle seeds ethanol extract (RSEE) belongs to a very strong category (50 μg /ml). This is due to the presence of several phenolic compounds and unsaturated fatty acid derivatives
