“…Robusta coffee with decaffeination in 90% waste concentration for 9 hours has the highest antioxidant activity of 17,6061. A natural ingredient is said to contain very active antioxidants, if it has an IC50 of less than 50 ppm (Budryn et al, 2017;Fitmawati et al, 2017;Gebeyehu & Bikilla, 2015;Iswari & Susanti, 2016).…”

Robusta is the most widely cultivated coffee in Indonesia (90% of the total Indonesian coffee production). Antioxidant activity and polyphenol content of Robusta coffee is higher than Arabica coffee or the other plants. One of the efforts, for coffee market expansion is product diversification through decaffeination of coffee . Decaffeination is one of process to reduce caffeine content. Decaffeinated coffee (decaff coffee) began to become public demand. In addition to its more delicious taste, low caffeine coffee is beneficial for health because it is safer to eat. Coffee decaffeination can utilize organic solvents that contain proteases. Tofu waste was one of protease sources. So that, tofu waste had potential as solvent in decaffeination The objective of the study was to assess the antioxidant activity of Robusta green coffee after going through decaffeination by using tofu waste. The study was used Factorial Completely Randomized Design, i.e . concentration of tofu waste (30%,60%, 90%) and length of immersion (3, 6, 9 hours). Robusta green coffee antioxidant activity was examined by using DPPH method. The results showed that the highest antioxidant activity ( 17.6061) was in the treatment of 90% waste concentration and 9 hours of decaffeination time. In conclusion, the greater the concentration and the longer the decaffeination resulted in the higher antioxidant activity. This study provides information about coffee processing methods that can produce coffee with the best quality. So, It can increasing the value of domestic coffee products especially in the global market and utilizing tofu liquid waste to be more malleable.

Cardiovascular disease caused by hyperlipidemia is the highest case in term of fatality of non-infectious disease in Indonesia. Cnidoscolus chayamansa is well known as a herb that has nutraceutical potential for medicine and likely as a hypolipidemia agent. Therefore, this study aimed to identify the optimal dose of C. chayamansa as a candidate to treat cardiovascular diseases. A total of 30 white rats were acclimatized in the laboratory for 14 days. After that, the rats were grouped into six groups, randomly, which including a healthy control group (K0), a negative control group or hyperlipidemic rats (K-), a positive control group or hyperlipidemia-induced rats that was supplemented with atorvastatin (K+), then a hyperlipidemic rats treated with alcoholic extract of C. chayamansa leaves at doses of 100 mg /kgBB /day for K1, 200 mg/ kgBB/ day for K2 and 400 mg/ KgBB/ day for K3. The results showed that K3 treatment is the most effective and optimum dose for lowering total cholesterol level at 76.81±1.10 mg/dl, triglycerides 72.39±1.66 mg/dl and LDL-C at 21.47±0.58 mg/dl. The aortic histology assessment also showed that the K- group had putative thrombus or plaque in intima, and it was not found in other groups. This research focused on the optimum dose and new usage of C. chayamansa, as an anti-inflammatory in atherosclerosis. By understanding the optimum dose of C. chayamansa, the community can apply and control the herb consumption for their own therapeutic properties. For future application, the herb is potentially developed as anti-atherogenic medicine.

“…Tomato plants are one of the popular foodstuffs because they are known to have content that is beneficial to health, namely vitamin E, ascorbic acid, and lycopene which can act as antioxidants. Apart from being used as food, as an edible vaccine candidate, tomato plants are also used for scientific purposes (Concha et al, 2017;Gill and Kaur, 2019;Iswari & Susanti, 2016;Paduchuri et al, 2010;Raiola et al, 2014;Setiaji et al, 2020;Wu et al, 2011).…”

Effect of 6-Benzylaminopurine (BA) and Paclobutrazol (PBZ) with Light Intensity Variations for Cherry Tomatoes In vitro Flowering

et al. 2022

Utilization of Solanum lycopersicum L. and its varieties contribute to plant biotechnology to study the effect of genes and flower transition events. This study aims to optimize media and light intensity for in vitro flowering of a cherry tomato variety. Induction of flowering was carried out using seven types of media combined with 3 light intensities, followed by feeding by adding liquid medium MS+PBZ 1 mg/L. A positive response is shown at the light intensity of 2,600 lux; there are 5 explants that have flower buds. The percentage of flower buds for each treatment combination was 50% from two replications. The first shoots occurred at 142 days after planting (DAP) on explants grown on media containing 0.5 mg/L BA, 0.75 mg/L PBZ, with feeding treatment. It can also be assumed that the emergence of flower buds occurred not because of the PGR induction treatment, but because at that time the explants had entered the generative phase, considering that the plantlets had been growing for a long time. Although the effects of BA and PBZ have not been confirmed, the use of 2,600 lux light appears to be the best condition for cherry tomato in vitro flowering induction.
