Introduction: Plumbum (Pb) is the main air pollutant in urban areas, is one of the heavy metals contained in motor vehicle fuel. Pb is a heavy metal that will trigger the formation of Reactive Oxygen Species (ROS), can reduce the activity of antioxidant enzymes and cause oxidative stress in the kidneys. Tender coconut water contains compounds that are as antioxidants that can protect the effects of free radicals caused by Pb. This study aims to prove the effect of tender coconut water on ureum levels in wistar strain rats exposed to plumbum (Pb). Method: experimental research with posttest only control group design. The independent variable was administration of tender coconut water, while the dependent variable was ureum levels. The study population was wistar strain male rats that were kept in the Penelitian Antar Universitas (PAU) Gajah Mada University, Yogyakarta. The eighteen male wistar strain rats used in this study were divided into 3 random groups, namely the K1 (control); K2 (Pb of 10 mg / day given inhalation); K3 (tender coconut water 8mL /200grBW). Urea levels were analyzed by the Kruskal Walls test, because the data distribution was not normal. Results: The mean ureum levels K1: 11,13 ± 0,51 mg / dL; K2: 52.85 ± 1.97 mg/dL; K3: 19.71 ± 1, 25 mg / dL. The mean ureum level in K2 was higher with K1 and K3, but in K3 it decreased when compared to K2 although it was still higher than K1. The analysis test results obtained p: 0,000 (p value <0.05). Conclusion: Administration of tender coconut water is proven to reduce urea levels in wistar rats exposed to Pb.

Sensitive period is the right time to instill the basis of the importance of counting. In addition to counting skills that must be developed also pay attention to the application of learning used. However, in the learning process, teachers often forget the importance of playing methods. If too often with giving assignments the child will feel bored, therefore what is used is the method of playing. Play method is one method that can be used by teachers to teach the ability to count children in the beginning. Based on this background, the purpose of this study was to determine the effect of the use of playing methods on initial numeracy skills. This study used the Quasi Experiment method with the Nonequevalent Control Group Design research design. The results of the pre test showed that there were no significant differences in the experimental group and the control group with p-value> 0.05, which was 0.135> 0.05 which was tested by the two average test results. While the post-test results showed that the initial numeracy ability after the application of the playing method experienced a significant difference with the p-value <0.05, that is with the results of 0.0001 with the Mann-Whitney test. This method of playing can be used as a learning suggestion for educators to improve their ability to have an early start.

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

Abstract: Dental caries is a disease that attacks the hard tooth tissue. One of the causes of dental caries is the acidogenic bacteria. The bacterial growth is influenced by the condition of oral cavity such as the pH of saliva. The acidity of salivary pH causes increased growth of bacteria resulted in higher risk of caries. Various methods are used to reduce the risk of dental caries. One of them is the usage of natural materials that contain calcium such as coconut water (Cocos nucifera L.) that can help the remineralization process, therefore, can pH of saliva will increase. This study was aimed to determine whether the coconut water and improve the pH of saliva. This was a quasi experimental study with a pretest and posttest group design. There were 30 people as samples. Salivary pH measurements were done three times in each sample as follows: normal saliva, saliva after consumption of bread, and saliva after drinking coconut water. Salivary pH was measured with a pH meter. The results showed that coconut water did not increase the pH of saliva because its pH was acid and its sugar content lowered the pH of saliva.Keywords: salivary pH, coconut water, dental caries, coconut water to pH of saliva Abstrak: Penyakit karies gigi merupakan penyakit yang menyerang jaringan keras gigi.

Dysmenorrhea is a common cause of pain in young women. The discomfort of dysmenorrhea causes unstable emotions, sleep disturbances, diet changes, and increased stress and depression that can degrade women quality of life. This non-pharmacological Randomized Controlled Trial aimed to obtain the optimal dose of green coconut water as a magnesium source for reducing dysmenorrhea pain. Twenty-one participants divided into three groups. Treatment group 1 obtained 330 ml of green coconut water, treated group 2 obtained 165 ml of green coconut water, and the control group obtained 330 ml of mineral water where each dose repeated three times every 4 hours. VAS questionnaire used to measure the value of pain intensity before and after administration. The 330 ml green coconut water dose is the effective dose compared to control (VAS=4.14, p=0.000), while another dose has a weak effect (VAS=1.86, p=0.124). This finding proves that green coconut water can be a non-pharmacological alternative in handling dysmenorrhea pain.
