Background: Football players requires a high level of VO2max which is influenced by the available of energy. Tender coconut water and branded isotonic are as energy drinks containing of carbohydrates and the body’s electrolyte ions that can prevent dehydration. The increasing pulse describes a the condition of dehydrated players during match or training. Objective: To Examine comparison of tender hybrid coconut water and branded isotonic to pulse and the plyer’s level of VO2max in the Diponegoro University Football School in Tembalang, Semarang. Methods: Experimental study with an approach of randomized pretest - post test control group design at 41 soccer’s player aged 13-15 years at Diponegoro University Football School Tembalang in August 2015. The treatment group consumed consumed 250 mL tender coconut water (n=13) and branded isotonic (n=14) and group control consumed mineral water (n=14) every 15-30 minutes for 5 times. Observation  pre test and post test 1,2,3 with interval of 3 day after physical training, athlets test the pulse to palpation techniques for 15 seconds and VO2max test with multistage fitness test. Result: The VO2max and pulse recovery in the beginning of research for 3 group was similar (p = 0,454 and p = 0,294). Post test 1 VO2max on three group are same (p = 0,841) but the recovery pulse is better on the group of tender coconut water and branded isotonic (p = 0.006). Post test 2, VO2max and recovery pulse is more good by players who were given tender hybrid coconut water and branded isotonic (p = 0,004 and p = 0,017), as the same post test 3 VO2max and recovery pulse (p = 0.000 and p = 0,004).Conclusion: Giving the tender hybrid coconut water and branded isotonic to same to recovery pulse and increased VO2maks on athlete school football diponegoro unversity

The effect of pulsed light on the survival of E.coli MTCC 433 in tender coconut water was investigated. The sterilized liquid samples were inoculated with E.coli @ 1010 cfu/ml and treated with pulsed light intensities of 0.18, 2 and 5.6 W/cm2 for an exposure time between 0 and 15 sec. The results obtained were fitted with three different models such as log linear plus tail, Weibull and biphasic model. Biphasic model showed the best the performance with 7 smaller RSME values of 9 evaluated kinetics followed by Weibull model. Among the three models, biphasic model fitted well with the inactivation of E.coli MTCC 433 by using pulsed light treatment

Coconut water is a nutritious, natural, and refreshing drink. However, a challenge for the coconut water industry is its fast deterioration caused by naturally occurring enzymes mainly polyphenol oxidase (PPO) and peroxidase (POD). This study aimed to separate the PPO and POD using ultrafiltration and to evaluate its effect on the physicochemical properties and antioxidant attributes of tender and mature coconut water. The membrane used was polyethersulfone (PES) with two molecular weight cut-offs, namely 30 kDa (PES 30) and 50 kDa (PES 50) and conducted in a vacuum filter unit. The results showed that ultrafiltration with PES 30 completely separated the POD activity of both tender and mature coconut water. The ultrafiltration was also able to separate 86.07% PPO activity of tender coconut water and 100% separation on mature coconut water. While PES 50 could separate 49.60% PPO activity in tender coconut water. The ultrafiltration process also increased the clarity of mature coconut water and maintained the total sugar, sodium, and potassium contents in both maturities. However, ultrafiltration using these membrane types reduced total phenolic content and radical scavenging activity. In conclusion, this study revealed that ultrafiltration can remove the oxidative enzymes to extend the shelf life against oxidation deterioration. Further studies should be conducted to investigate the separation of enzymes without high significance loss of polyphenols, antioxidants, and nutritional properties

The purpose of this research is to determine the concentration of young coconut water that is appropriate for the growth of orchid plantlets (Dendrobium sp.) In vitro. This study used an experimental method, descriptive data analysis to compare several different concentrations of coconut water. The design of this study uses a completely randomized design (CRD). The treatments consist of 0% coconut water concentration (as a control), 15%, 30% and 60%. Each concentration was carried out 5 replications and each repetition consisted of 5 Dendrobium sp plantlets in each culture bottle conducted for 40 HST, for observing the root length carried out for 50 HST. The highest number of shoots and leaves were produced at the same concentration, namely 150 ml / L coconut water treatment (15% concentration) with an average of 2.8 shoots and the average number of leaves 10.8 leaves. The average number of roots and the longest root length was produced at a concentration of 600 ml / L coconut water (60% concentration) with an average of 6 roots, and the longest root length was 0.5 cm.Keywords: Young coconut water, (Cocos nucifera L.), Dendrobium sp., in vitro, growth.ABSTRAKTujuan penelitian ini ialah menentukan konsentrasi air kelapa muda yang tepat untuk pertumbuhan planlet anggrek (Dendrobium sp.) secara in vitro.
