Background: Green coconut water is a most popular functional drink in all tropical countries. The presence of toxic heavy metals in surface seawater is a major problem globally, with a large share in developing countries like Bangladesh. The objective of the study was to assess the concentration of heavy metals like Pb, Cr, Ni, Cu, and Cd in green coconut water and surface seawater around sea beach areas of Bangladesh. Methods: Green coconut water and surface seawater samples were collected from six sea beach areas and transferred to the laboratory. Then, they were allowed for digestion, and finally, the concentration of heavy metal was assessed by the atomic absorption spectrophotometer (AAS). Results: In green coconut water, the concentrations of heavy metal exist bellowing the safe limit with the following order: Pb > Cr > Cu > Ni > Cd. But, Pb, and Cr were prevalent in surface seawater and found to decrease in a sequence of Pb > Cr > Ni > Cd, Cu. Besides, Human health risks associated with the intake of these metals were evaluated in terms of metal pollution index (MPI), daily intake of metals (DIM), health risk index (HRI), and hazard index (HI). However, most of the index values were found to be bellowing the reference value. Conclusion: The concentration of green coconut water is almost proportional to surface seawater in sea beach areas. The high prevalence of Pb and Cr in surface seawater is alarming, and this impact is already seen in green coconut water. So, it is necessary to take action on seawater pollution in Bangladesh.

Background: High number of teenage marriages is a very worrying phenomenon because it causes various negative impacts on both reproductive health and social life. Indonesia is ranked second in ASEAN and eighth in the world for cases of early marriage. In the Mlarak sub-district, Ponorogo Regency, 8% of marriages were under 19 years of age. The purpose of the study was to determine the effectiveness of the Problem Based Learning (PBL) method to increased students knowledge and attitudes about early marriage. Method: Research design was pre- experimental with a pretest - post test one group design. The sample was class VIII SMP Negeri 1 Mlarak, Ponorogo Regency, taken by proportional random sampling technique followed by Simple Random Sampling as many as 60 students. Collecting data using a questionnaire instrument. The independent variable is the PBL method while the dependent variable is knowledge and attitudes about early marriage. Data analysis used Paired Sample T Test with 0.05. Results: The results showed there is increase in the average knowledge of student by 14.08 and student attitudes by 12.2 after using the Problem Based Learning method. The results of the Paired Sample T Test 0.000 for the knowledge variable and 0.000 for the attitude variable, which means Ho is rejected and Ha is accepted. Conclusion: PBL method is effective in increasing knowledge about early marriage. The PBL method is effective in increasing attitudes about early marriage. Suggestions for teenagers to increase their knowledge about early marriage so that students attitudes about early marriage can increase.

Background: Stunting is a public health problem that is associated with an increased risk of morbidity, death and obstacles to both motor and mental growth. This research aims to determine the effect of family education on maternal nutritional behavior for toddlers who experience stunting in Madura, Indonesia. Method: The type of research was quantitative analytical observational, the research design used in this research is Quasi Experimental with a Two Groups Pre-test Post-test with Control Group Design. The population is all stunted toddlers who were registered at the Community Health Center in Madura Indonesia, totaling 78 children and their mothers. The sample was 65 people using simple random sampling technique consisting of 33 control groups and 32 treatment groups. Data collection uses a questionnaire. The variables studied are the incidence of stunting in toddlers as the dependent variable and the independent variable is the mothers nutritional behavior. Result: The research results of the Wilcoxon test analysis showed that there was a significant influence on the average score of maternal nutritional behavior before and after being given family education, with a p-value of 0.001, namely p<0.05. Conclusion: There is an influence of family education on maternal nutritional behavior for toddlers who experience stunting in Madura Indonesia.

Background: The complex problems of different chronic degenerative diseases are spreading in human health across the globe. To combat this problem, fruits are the effective gear proved by many epidemiological studies. The aim of the study was to determine the antioxidant activity and three bioactive compounds like total flavonoids, total polyphenols and total anthocyanins in 23 species of fruits available in Bangladeshi market. Methods: Antioxidant activity (AOA) and bioactive compounds of fruits were determined by UV-visible spectroscopy. Antioxidant activity was undertaken by DPPH scavenging assay, total polyphenol content (TPC) was measured by folin-ciocalteu method and total flavonoid content (TFC) content was measured by aluminium chloride colorimetric method. Results: Among 23 species of fruits, AOA was higher in Katajamin (303 mg/100 g) followed by Dragon Fruits (171 mg/100 g), Guava (131 mg/100 g), Bael (130 mg/100 g) and average value was 125 mg/100 g of extract. TPC was varied from 10 to 305 mg GAE/100 g and average value was 87 mg GAE/100 g. Mango (305 mg GAE/100 g) showed higher TPC, followed by Pome Granate (222 mg GAE/100 g), Apple (207 mg GAE/100 g), Katajamin (141 mg GAE/100 g) and Bael (130 mg GAE/100 g). Again, TFC was ranged from Ashari (06±3.94 mg QE/g) to Tomato (84±13.69 mg QE/g) and the average TFC was 37 mg QE/g. In addition, total anthocyanin content (TAC) was highest in Mango (142±3.46 mg TA/100 g) and lower in Ashari (02±0.74 mg TA/100 g). There was a significant correlation (p=0.05) between antioxidant activity and bioactive compounds and among the bioactive compounds. Conclusion: Important messages from this study are, majority of the rare fruits are the important sources of antioxidant and bioactive compounds which helps to reduce the risk of chronic degenerative diseases and can be used in food processing industry for nutraceutical product development.
