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

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

PENGARUH DOSIS PUPUK ORGANIK SARI ALAM DAN PUPUK PETROBIO TERHADAP PERTUMBUHAN DAN PRODUKSI JAGUNG MANIS (Zea mays sacharata) VARIETAS TALENTA

Sweet corn needs continue to increase along with the increase in population and the increase in processed foods made from sweet corn. In Indonesia the yield of sweet corn is classified as low, which is 3.5 tons / ha, while the potential for sweet corn production currently reaches 8.31 tons / ha. To meet the needs of sweet corn in the community that continues to increase, it is necessary to have an effective cultivation system by utilizing organic fertilizer, so that we get healthy products, safe for public health and the environment. This study aims to determine the interaction between the dose of Sari Alam organic fertilizer and Petrobio fertilizer on the growth and production of sweet corn (Zea mays sacharata) Talenta variety. In this study using factorial randomized block design. Observative vegetative parameters include plant height, stem diameter, and leaf area. While the harvest parameters include weight of corn cobs with weights, weight of corn cobs without weights, cob length without weights, Sugar Level Analysis (%). From the results of the study there was a very real interaction on the combination treatment of organic fertilizer dosage of natural juice and petrobio S3P2 fertilizer (dosage of natural extract 44gr / plant, petrobio dose 0.5gr / crop) at the observation of plant height at the age of 21 days and stem diameter at 28 days . There was a significant effect on the single factor dosage of S3 natural fertilizer organic fertilizer (dose 44gr / plant) on the weight of lobed cob
