Abstract

Cayratia trifolia leaves contain flavonoids compound that can dissolve well in polar solvents. This study aimed to evaluate the total flavonoids content of polar extracts which extracted sequentially from C. trifolia leaves. The dried C. trifolia leaves were macerated continually using n-hexane, ethyl acetate, and ethanolic solvent. The total flavonoids content was determined using spectrophotometric methods with a AlCl3 reagent. TLC chromatogram of the extracts were evaluate using chloroform: aceton: formic acid (10:2:1) as a mobile phase and silica gel F254 as a stationary phase. The citroborate and ammonia vapour were used as detection spray reagents. The highest total flavonoids content (27.95±0.62 mgQE/g) were found in 70% ethanol extract of C. trifolia leaves compared to ethyl acetate extract (17.98 ± 0.89 mgQE/g). The ethanolic extract is found six compound spots, while the ethyl acetate extract found four compound spots which were thought to be a flavonoid group. Thus, it can be concluded that the different polar extracting solvents are able to attract flavonoid compounds with different levels. The flavonoids in C. trifolia extract need to be separated to determine the types.

Abstract
Robusta coffee processors in Indonesia apply three methods of processing cherry coffee into green coffee beans, which can affect the quality of the coffee produced. Therefore, this study aims to determine the effect of those various processing methods on the coffee beans by finding out differences in Robusta coffee samples’ biochemical content, both as a pulped and green bean. Red-picked Robusta coffee samples were collected from the Kepahiang Bengkulu, one of Indonesia’s highest Robusta coffee producer areas. The primary biochemical contents of coffee, such as moisture, caffeine, chlorogenic acid, sucrose, and lipids, were tested using standard methods on cherry, pulped, and green bean samples. We observed that both pulped and green bean samples showed significant differences (p<0.05) in their biochemical content. Therefore, selecting the right processing method is necessary to get green beans with biochemical content that will produce coffee with preferable sensory attributes.

AbstractThe people of NTT, especially the Timor region, have still maintained their customs for generations. The use of natural dyes has also been increased to reduce environmental pollution due to the use of synthetic dyes that have the potential to contain heavy metals. There are more than 30,000 - 40,000 plant species in Indonesia and 150 of them are plants that can produce natural dyes. Indigofera spp. is a kind of natural blue plant. The problem faced in the use of plants as natural dyes is the availability of raw materials. So far, Timorese only harvest Indigofera spp which grows naturally from the environment around the house or in the nearby forest so that it cannot meet the needs on an industrial scale. This study aims to conduct cultivation techniques of 2 species of Indigofera and postharvest techniques to get the optimal blue color. The seeds used are the result of exploration from plants in Bosen, NTT and plant collections available at BPPTH Nursery, Nagrak, Bogor; Indigofera suffruticosa and Indigofera sp. The planting technique uses a completely randomized design (CRD) with 2 factors (2 species, 4 doses of humus). Each treatment combination consists of 3 replications. For postharvest techniques for making indigo paste using completely randomized design (CRD) with 2 levels of lime concentration. I. sufruticosa much better growth by adding humus at a dose of 1500 g/tree shows better branch improvement. For postharvest soaking techniques, it is enough to do 24 hours with the addition of 4% lime concentration.
