environment. Housewives have an enormous role in modeling their families in comparison to fathers. Housewives are also more dominant in managing the food menu and maintaining the sanitation of the house, not to mention they also participate in providing education and knowledge and instilling the value of environmental sanitation in the family. High environmental knowledge will make it easier for housewives to keep the environment clean.
The purpose of this research to understand the impact of knowledge and perception of environmental sanitation towards environmental sanitation behavior in the society of Semarang city.

LITERATURE REVIEW
The concept of environmental sanitation entails the control of water supplies, excreta disposal, waste water disposal, refuse disposal, vectors of diseases, housing conditions, food supplies and the safety of the working environment (Acheampong, 2010). Environmental sustainability could be defined as a condition of balance, resilience, and interconnectedness that allows human society to satisfy its needs while neither exceeding the capacity of its supporting ecosystems to continue to regenerate the services necessary to meet those needs nor by our actions diminishing biological diversity (Morelli, 2011). The Concept of Environmental Sanitation for Maintenance by Soekidjo Notoatmodjo (2007) suggests that environmental health in developing countries ranges from sanitation, drinking water, housing, garbage disposal, and waste water disposal.
Sanitation becomes an important factor to shape the personality of a person, a region and even a nation. Everyone has the right and obligation to clean and healthy environment and garbage is one of the sources of the cause of non-existence of clean and healthy environment, waste management must be carried out consciously, integrated and directed between each individual society and government (Nazarudin, 2014). Environmental sanitation obstacles factors are as follows. 1. Environmental-friendly development costs a lot. 2. The lack of shame culture so that people do not hesitate to throw garbage anywhere, anytime, and in front of anyone 3. lack of knowledge and understanding of society about the dirty environment hazard due to garbage, waste, and pollution. 4. Lack of knowledge about waste utilization and waste management.
Knowledge of environmental issues and appropriate actions to overcome them become one of the prerequisites for responsible behavior. Having knowledge and ability is not enough. Desire to realize the action of environmental sanitation is necessary. One's desires are strongly influenced by personality factors, namely attitude, locus of control and sense of responsibility. Knowledge is also influenced by factors of education, occupation, age, interest, experience, culture, environment, information. Individual knowledge about health risks is known to profoundly influence risk perception which, in turn, affects a person's attitude. Thus, an individual's knowledge, perception, and attitude are fundamental in determining how people behave about environmental hazards (Dhitinut Ratnapradipa, 2011). Results of research by Aswanthy (2015) stated that there is a positive correlation between level of knowledge and standard of practice. However there is no association between knowledge and practices of environmental sanitation and hygiene with selected socio personal variables.
Environmental perception has been defined as information processing system in which individuals actively explores their surroundings and extract and use information in constant interaction between themselves and their environment (Byoung, et.al, 2006). The importance of studying environmental perception stems from the fact that several spects of man's daily living are affected by his perception (Oluwole Daramola, 2016).
The study concluded that for homes and schools to act as correlates of evolving sustainable sanitation behavior among these future adults, teaching on how to develop good hygiene behavior must be matched with corresponding provision of environmental sanitation amenities (Afon, A.O. et.al, 2008). To determine how individuals behave when it comes to reducing risks associated with environmental health, four subscales evaluating student behaviors toward environmental health issues were analyzed: personal-level issues, food consumption practices and noise pollution, everyday recycling, and exercise. Results indicated that a person's attitude did predict whether a person engaged in behaviors that would reduce or eliminate the risk associated with environmental health issues. Additionally, there were knowledge and demographic variables that were determined to be significantly associated with two behavior subscales: food consumption practices and noise pollution, and everyday recycling (Dhitinut Ratnapradipa, 2011) The sanitation behavior observed is in the form of a series of various forms of behavior/actions that people do toward garbage, including environmentally responsible behaviors such as environmental soiling actions to responsible actions such as actions to preserve and clean the environment.

METHODS OF RESEARCH
The population in this study is the entire housewives aged 30 to 60 years old in Semarang City. While the samples are 100 housewives aged 30 to 60 years from the Sumurboto, Ngesrep and Karang Bendo Administrative Village in Semarang City. The minimum sample size is using Eq. (1).
Sampling Technique and Data Collection Method. Sampling technique used in this research is non-probability sampling. Type of sampling used is purposive sampling. Purposive sampling is a sampling technique based on certain considerations; the selected samples in the study are housewives aged 30 -60 years. After the data are collected, the questionnaire is analyzed through its validity and reliability to get feasible data for the research.
In order to measure the validity test, questionnaire or indicator is said to be valid, if r arithmetic > r table, that is comparing Total Item value -Total Correlation with result of r table calculation. Testing reliability with Cronbach alpha () statistical test. A construct / variable is said to be reliable, if it gives the value of cronbach alpha ()> 0.60.

RESEARCH MODEL AND HYPOTHESIS
The first hypothesis, about the presence or absence of positive and significant impacts between knowledge variables on environmental hygiene maintenance behavior and second hypothesis about the presence or absence of positive and significant impact between perceptual variables on the behavior of environmental hygiene  Table 1.  (Ghozali, 2011). A questionnaire is declared valid if the question on the questionnaire is able to reveal something that the questionnaire will measure. Validity test is done by comparing between r values counts with r table. If r count is greater than r table and positive value then the item or question or indicator is declared valid and vice versa (Ghozali, 2011).
The amount of sample which was used in testing research instrument was 30 respondent with df (degree of freedom) = n -2 = 30 -2= 28. On 5 % error -range therefore, the value of r tabel = 0,374. The result of validity test is presented below. The results of the validity test in table 2 shows that all question items used in this study have the value of r count greater than the r table (r count> 374). Therefore, it can be concluded that all the questions of each research variable can be said valid.
Reliability Test. Reliability is a tool for measuring a questionnaire which act as an indicator of a variable or construct (Ghozali, 2011). A questionnaire is said to be reliable if one's response to a statement is consistent or stable over time. Respondent's answer to this question is said to be reliable if each question is answered consistently or the answer should not be random because each question wants to measure the same thing. If the answer to this indicator is random, then it can be said that it is not reliable. The test equipment used is Cronbach's Alpha. With the following conditions:  If cronbach's alpha (α) > 0,6, then the questionnaire can be considered reliable.  If cronbach's alpha (α) < 0,6, then the questionnaire can be considered unreliable.
The results of reliability test, can be seen in Table 3. The results of reliability tests in table 3 showed that all variables in the study has a value of cronbachs alpha greater than 0.60 so it can be said all the measuring concepts of each variable of the questionnaire is reliable which means that the questionnaire used in this study is a reliable questionnaire.
Data Analysis Technique. To prove the first hypothesis, about the presence or absence of positive impact and significance between knowledge variable about environmental sanitation to environmental sanitation behavior and second hypothesis about the presence or absence of positive impact and significance between perception variable about environmental sanitation to environmental sanitation behavior, multiple linear regression analysis tool was used.
In order for multiple linear regression models to be used in this study, normality test and classical assumption test consist of heteroskedasticity, and multicollenearity test. Based on the calculations it fulfills the classical assumption.

RESULTS AND DISCUSSION
Equations of multiple linear regression lines based on calculations using SPSS version 22 obtained the following results: From the multiple linear regression analysis above it can be seen that the regression coefficient between knowledge about environmental sanitation (X1) to environmental sanitation behavior (Y) is 0.840 with significance of 0.000. This means there is a positive and significant influence, meaning that with knowledge about good environmental sanitation will increase the behavior of environmental sanitation significantly (meaning). Regression coefficient between perception about environmental sanitation (X2) to environmental sanitation behavior (Y) equal to 0,025 with significance 0,414. This means that there is a positive and insignificant effect (because sig <0,05), meaning perception of good environmental sanitation will improve environmental sanitation behavior but not significant (meaningless).
Classical assumption test consisting of normality test, heteroskedasticity test and multicollinearity test have fulfilled the requirement that multiple linear regression analysis can be used to analyze this research.

CONCLUSION AND SUGGESTIONS
The result of multiple linear regression analysis shows that: (a) there is positive and significant influence between knowledge about environmental sanitation to behavior for environmental sanitation, (b) there is a positive and insignificant influence between the knowledge of environmental sanitation to behavior for environmental sanitation Based on the responses of housewives about the knowledge, perception and behavior of environmental sanitation in the discussion, it is suggested: (a) The impact of perceptions on behavior that is not significant, so it needs to give understanding and understanding about environmental sanitation to the community, (b) There needs to be counseling about environmental sanitation especially related to household waste because many of housewife who have not done waste segregation to be organic and inorganic, and (c) the need for counseling about public health with less clean environmental conditions Recommendations in this study include: (a) the need to be counseling about environmental sanitation especially about pollution and clean & healthy food, (b) the need to be counseling about environmental sanitation especially related to household waste, c) the need for counseling about public health.
