Strategy is a way that is used to apply access from thought ideas that are poured into concrete actions. In this context, strategy is the basic reference for implementing religious culture at MTs Ma'arif NU Randegansari. Religious culture has a meaning that smells of Islam with its application to produce cognitive and affective learning in schools. Values, meanings, norms in religious culture are the main foundation for determining the right steps to know and understand what is the meaning behind religious culture at MTs Ma'arif NU Randegansari. The focus of this thesis research is: What is the Strategy for Implementing Religious Culture at MTs Ma'arif NU Randegansari. This study uses a qualitative method with a case study approach, while the data collection technique used is the method of observation, interviews, documentation. In this study, the researcher used a triangulation data validation test. In this study, the results were found from research using interview, observation, and documentation methods. The results of interviews with school principals, deputy principals, and religion teachers at MTs Ma'arif NU Randegansari show that the strategies for implementing religious culture in students are: 1) through example or giving examples, 2) getting used to good things, 3) upholding discipline, 4) providing motivation and encouragement, 6) through advice (mauidzah), 5) creating a religious atmosphere for students. The strategy used to cultivate religious values at MTs Ma'arif NU Randegansari is a persuasive strategy which is a way or an attempt to be able to influence the attitudes, opinions and behavior of students both verbally and nonverbally. Persuasive strategies are not coercive, changes in attitude or behavior come from personal encouragement. Thus persuasive strategies create more consistent attitudes and behaviors. directing smoothly will prevent students from feeling afraid and coerced when students do something that is actually an order from the teacher.

Noise exposure can occur at any time and interfere with a person's psychological and biological condition. Alternative materials from banana midrib and soybean dregs can be used as sound absorbers based on their characteristics and abundance. This research aims to analyze the optimal composition for sound-absorbing composite materials from banana midrib and soybean dregs and the effect of adding a layer of varnish to its absorption capacity. The method includes the manufacture of the sample, the impedance tube, the box acoustic approach, and the CCD test. The drying process of banana midrib is divided into two types, namely those that are dried in the sun and oven with the banana midrib having gone through a 5% NaOH immersion process before drying. The application of varnish on the sample used the cold spray technique so the layer is not thick and provides durability and resistance to the sample. The impedance tube was carried out to analyze the value of the sound absorption coefficient of the sample at several frequencies which were then averaged. After being tested with the box acoustic approach, the sample has the ability to reduce sound when applied to the walls of the room with an average percentage decrease of 10.84%. Through the CCD test, it is known that the size and number of pores distribution affects the sound absorption capacity. Banana midrib and soybean dregs can be used as an alternative to sound absorbers with the average value meeting the ISO 11654 standard, which is 0.15.
