BACKGROUND: Mangosteen (Garcinia mangostana L.) rind had been known as an agriculture waste. However, some recent studies reported that Mangosteen rind had some health benefit. The rind (skin) of Mangosteen fruit was reported to contain compounds such as xanthones and anthocyanin antioxidants. There is a need to examine the chemical compound content of Mangosteen rind and the activities of antioxidants contained in the Mangosteen rind, so as to increase natural source of antioxidants for human health. This study aimed to produce ethanol extract of Mangosteen rind, to identify chemical compound content, and test its antioxidant activity. SUBJECT AND METHODS: Ethanol extract of Mangosteen rind was produced to identify its chemical compound content. The DPPH method was used to test Mangosteen's antioxidant activity with EC50 as a measure of the fruit potency. Half maximal effective concentration (EC50) refers to the concentration of Mangosteen fruit which induces a response halfway between the baseline and maximum states after a specified exposure time. The EC50 of Mangosteen and vitamin C were compared. RESULTS: Mangosteen rind extract consisted of saponin, tannins, polyphenol, triterpenoid, flavonoid, alkaloid and glycoside. The DPPH test of antioxidant activity showed that the EC50 of Mangosteen was 8.85 µg/ml, which exceeded the EC50 of 4.55 µg/ml in vitamin C. CONCLUSION: Mangosteen rind extract consisted of saponin, tannin, polyphenol, triterpenoid, flavonoid, alkaloid and glycoside. Mangosteen rind extract has a strong antioxidant activity.
The Sidimpuan Salak fruit was the mascot of Padangsidimpuan City, North Sumatra, Indonesia. In this study, Salak formulates to be a high-calorie food bar. The primary elements for making food bars Salak are purple sweet potato flour, tapioca flour, and dried salak fruit. The others elements were egg whites, margarine, emulsifiers, and high glucose syrup. All elements were mixed evenly and molded into bars with a size of 3×8×1.5 cm and a weight of 50 g. Food bars from roasted salak fruit used temperatures of 80, 90, and 100. The results showed differences in the proximate composition, calorific value, and dietary fiber content of the food bars salak. The most increased carbohydrate, fat, and calorie content get at a roasting temperature of 80°C, the protein and mineral content obtain most increased at a roasting temperature of 100°C, and the most increased food fiber gets at a roasting temperature 100°C. A high-calorie food bar Salak gets at a roasting temperature of 80°C.

Disarankan kepada tenaga kesehatan untuk menggunakan promosi sebagai upaya untuk mendukung program pemerintah dan mencapai target cakupan pemberian imunisasi campak rubella 95%
Anaerobic physical activity is a high physical activity because the muscles contract in anaerobic conditions. The energy used by ATP through the process of anaerobic glycolysis tends to produce more lactic acid.This, study aims to determine the effect of massage in reducing lactic acid levels after anaerobic exercise. Research on experimental studies using the Experimental Pre and Post-test design.Student subjects, male, aged 19-20 years, amounted to 16 people, divided into 2 groups, anaerobic exercise group without massage and a anaerobic group treat with combine massage. Examination of lactic acid is carried out after anaerobic physical activity which is 200 m run. Data were analyzed statistically using t test. We found that lactic acid levels after anaerobic physical activity were lower in the combination massage anaerobic exercise group than the non-massage anaerobic exercise group. Massage can reduce lactic acid levels after anaerobic physical activity.
The study was conducted to determine the effect of orange juice on muscle damage and leucocytes count of Tarung Derajat Athletes. Subjects were 10 athletes of Tarung Derajat, divided two group: orange juice (OJ) and placebo (PLA), quasi experiment study. Participant were randomized to consume 300 ml OJ or 300 ml PLA and exercise of Tarung Derajat for 12 d. Blood sample were obtained at baseline and 48 post-intervention. Measurement of muscle damage (creatine kinase/CK) and leucocytes count. OJ consumption was no effect on CK level (p=0,296 > 0,05) and significantly correlated on leucocytes count (p=0,005 < 0,05). OJ have effect on exercise-induced decreases leucocytes count, but no effect on muscle damage.
