Abstract

One of the causes of the environmental problems is the tofu industry. Disposal of liquid waste in the river causes water pollution. To find out how far the burden of pollution in wastewater is by measuring COD and pH. In this case aquatic plants such as water hyacinth are an alternative way to overcome the waste pollution. Aim from this study the use of water hyacinth (Eichhornia Crassipes) in reducing levels of COD (Chemical Oxygen Demand) and acidity (pH) tofu industry liquid waste in Tawang Village, Wates District, Kediri Regency. Based on the type of this research istrue experimental. This research design uses True post test only design with the focus of his research directed to be analyzed the use of water hyacinth in reducing levels of COD and pH of tofu industry wastewater with 3 types of water hyacinth variations in treatment namely 5, 7 and 9 applied with 5L of tofu wastewater is then tested by a laboratory. Analysis of the data used is One Way Anova. The findings found the average levels of COD and pH after the administration of water hyacinth with plant variation 9 is 865.80 mg / l and 7.7220 mg / l, plant variation 7 is 4617.80 mg / l and 7.7180 mg / l , plant variation 5 is 6422.00 mg / l and 7.7180mg / l. Based on statistical tests using One Way Anova get a value of 0,000 <0.05 so it is concluded that the averageCOD level of liquid waste of tofu industry which are given water hyacinth significantly different. Based on statistical tests using One Way Anova get a value of 0.001 <0.05 so it can be concluded that the averagepH of tofu industry liquid waste which are given water hyacinth significantly different. The results of this study can be a community solution to problems in the use of water hyacinth to reduce levels of COD and pH so that the quality of water contaminated by industrial waste can be overcome

Abstract

Health belief model is a model used to describe an individual's belief in healthy living behavior, so that the individual will carry out health behavior in the form of preventive behavior. This health belief model is often used to predict preventive health behavior. The health belief model is used to predict various health-related behaviors. The main concept of the Health belief model is healthy behavior determined by individuals in Bandar Lor Village, Mojoroto District, Kediri City.This type of research is analytical observational with a cross sectional approach with a sample size of 54 respondents, taken using the Porposive Sampling technique. The data analysis used was univariate, bivariate, univariate analysis and the Chi Square test. The results of this research show that the statistical test results of Perceived Susceptibility (p=0.306), Perceived Severity (p=0.503), Perceived Benefit of Action (p=0.301), Cues to Action (p=0.209) have no relationship with sexual behavior. Meanwhile, Self Efficacy (p=0.003) has a relationship with sexual behavior. Based on the research results, it can be concluded that the perception related to sexual behavior is Self Efficacy. So it is hoped that teenagers can learn and increase their insight into the impact of sexual behavior so that they can avoid negative sexual behavior.
