MEDIA ONLINE “MOGIGU” EFFECTIVE FOR INCREASING KNOWLEDGE ABOUT TOOTHBRUSHING ON ELEMENTARY SCHOOL

Dental caries is a dental health problem that is widely found in Indonesia. One way to improve a child's knowledge of maintaining dental and oral health is to provide dental health education on how to brush the teeth properly using appropriate and innovative tools or media. The type of research is quasi-experiment with pretest and posttest group design, sampling technique using Slovin formula. Media to increase knowledge is media online "mogigu" and offline media with a phantom. Differences between the groups in the test with the Wilcoxon and Mann Whitney tests. The results of the paired tests showed that counseling on how to brush your teeth using phantom media and using online media "mogigu" effectively increased knowledge of how to brush the teeth, a significant pretest and posttest value of p<0.05. The distributions in the two groups differed significantly showed that online media "mogigu" was more effective at increasing knowledge of how to brush the teeth than phantom media value p=0.000 (p<0.005). Media online "mogigu" more effectively improves knowledge on how to brush teeth than phantom media.


Introduction
Dental and oral health is an integral part of the overall health of the body so the maintenance of dental and oral health is important (Kemenkes, 2019). Dental and oral health cannot be separated from each other as it will affect the overall health of the body. According to the data, about 80% of Indonesians have damaged teeth for various causes, but the most common are caries or perforated teeth (Tambuwun;. To prevent the occur of teeth and to maintain good oral hygiene, one needs to maintain the cleanliness of his teeth and mouth by brushing his teeth properly and regularly. Brushing your teeth is a toothbrush or other tool (e.g. coconut fiber) with and or without toothpaste. Brushing your teeth every day is a routine tooth-cleaning activity every day outside of emergencies (illness, accident, crack or broken jaw, trismus or not being able to open the mouth), and other circumstances that do not allow a person to brush their teeth (Kemenkes RI, 2018) There are many things a human can do to keep his teeth and mouth clean. One of them is the awareness and behavior of the maintenance of individual oral hygiene. Ages 6-12 are the age of primary school children is an effective age to provide information that leads to the cognitive and skills of the child (Fatmasari, Purba, & Salikun, 2019). To improve dental and oral health maintenance efforts as well as especially in school age children needing special attention because at this age the child is in the process of growing. The state of the teeth will previously affect the development of dental health in adulthood (Prasko, Sutomo, & Santoso, 2016). Various ways can be done to influence the health behaviors of individuals, groups, or communities, one of which can be through health education. Counseling is considered to improve the knowledge and attitude of the participants who follow it (Yulinda & Fitriyah, 2018).
Knowledge is obtained as a result of stimuli captured by the five senses. Knowledge can be obtained naturally or in a planned way through the educational process. Knowledge is a very important domain for the formation of a person's behavior, the better the knowledge of how to maintain the health of a person's teeth and mouth, followed by awareness and behavior wanting to maintain the cleanliness of his teeth properly then it is more likely to prevent the caries (Tambuwun;. One way to improve the child's knowledge in maintaining dental and oral health is to provide dental health education on how to brush their teeth properly and using the right and suitable tools or media (Kristianto, Priharti, & Abral, 2018). One of the easy-to-use fortunetellers now is audiovisual media, which is an information-sharing medium that has audio (sound) and visual characteristics (images). This type of media has better capabilities because it includes both characteristics (Purnomo, 2014).
The delivery of counseling materials to the target in addition to having to comply with the method to be used must also be influenced by the absence of supporting media facilities for delivery. Demonstrations and other methods are one way of presenting information by showing the object directly or indicating a process or procedure for its implementation. This presentation is accompanied by the use of props and media as a material delivery tool. Effective counseling is given to less large (Prasko et al., 2016).
Mogigu is one of the innovations of the dental counseling method that uses audio and visual media in its presentation. Where audio involves the ear and visually involves the eyes, during counseling takes place students see and hear directly the instructions given by the counselor (Fatmasari, Santoso, Jati, & Utami, 2013).

Method
This type of research is Experimental Quasi which is with the design of research Group Pretest-posttest Design. This design makes the sample divided into two groups. In this design, observations are made twice before the experiment and after the experiment. The sample number is 75 elementary school-aged children who are divided into 2, the intervention group gets information about online media "mogigu" which can be uploaded via Youtube media while the control group gets counseling using phantom and toothbrush. Knowledge measurement is carried out before and after education for 2 weeks. Statistical test to measure differences in 2 groups using the Mann Whitney test.

Result and Discussion
Research conducted on students of SDN 01 and SDN 04 Klambu by providing counseling treatment on how to brush their teeth using phantom media and online media "mogigu" there are 17 question items used to increase knowledge about how to brush your teeth. At the research the condition of the sample in the study was active in following and very active in partitioning in the research.
Based on the research that has been done, the results obtained in the table below.  Jurnal Riset Kesehatan, 9 (2), 2020, 129 -131 The results from table 3 show that there was an increase before counseling was given using phantom and after counseling was given using phantom categories both from 26% to 52%. Table 4. Distribution student knowledge frequency before and after being given counseling using online media "mogigu" The results from table 4 show that there was an increase before counseling using online media "mogigu" and after counseling which is a category well before 22% while after 83%. Because the data is categorical and distribution is abnormal (non-parametric), then to know the effectiveness of "mogigu" compared to phantom used test different pairs Wilcoxon and different test not paired Mann Whitney. Table 5. Students' knowledge test results before and after counseling using phantom media.
Based on the table above, the calculation result Wilcoxon rank test shows, value p=0.003 which is <0.05. Ho was rejected, meaning there was a difference in students' knowledge before and after being given counseling using phantoms.
Students' knowledge of dental health, especially how to brush their teeth before being given knowledge on how to brush their teeth by talking method with phantom media and after counseling using phantom media is increased.
Increased knowledge occurs because at the time of counseling using phantom students demonstrated how to brush their teeth well and properly. This shows that providing information using interesting demonstrations and a pleasant atmosphere can make it easier for respondents to receive the information provided (Hestiani, Yuniar, & Eka Meiyana Erawan, 2017).
According to Susilawati, Damayanti, & Azhari (2017), in counseling, the materials provided must be tailored to the objective. The material (knowledge) given at the time of counseling can be distinguished based on the grade level, for example, grades IV and V students who are 10-11 years old, the mindset has been somewhat developed, so the right counseling material is to use props in the delivery of materials. The props used in this study are phantom dental media used to improve students' knowledge of how to brush their teeth as a means of providing information on how to brush their teeth well and properly to students.
This research is in line with research conducted by (Hestiani et al., 2017) which states that there has been a change in students' knowledge before and after counseling using demonstration methods. And this research is also in line with research conducted by (Aritonang dan Purba, 2017) in the study it can be concluded that there was a significant change in the knowledge of students given counseling using phantom media. Based on the table above, the calculation result Wilcoxon rank test shows, value p=0.000 that is < 0.05. Ho was rejected meaning there was a difference in students' knowledge scores before and after being given counseling using the online media "mogigu" The knowledge of students before being given counseling using audiovisual media or in this case online media "mogigu" and after counseling, there is an increase in monitoring. This occurs because online media "mogigu" uses media involving audio and visual. Where audio involves the ear while the visuals involve the eyes as senses Yulinda and Fitriyah (2018). This is also in accordance with the opinion expressed by Notoatmodjo (2010) which states that the senses that channel knowledge a lot are the eyes around (75%-80%) This study is in line with research conducted by (Fatmasari et al., 2019) which mentions that the use of online media "mogigu" is effective in improving students' skills because at the time of counseling on how to brush their teeth see and listen directly to the instructions given so that the information obtained will be more easily received and digested by the child.  Based on the table above it can be known that these results lead to a difference in the increased knowledge of students given phantom media and online media "mogigu". Based on the different tests not paired using Mann Whitney obtained p-value 0.000 < (0.005), this shows that online media "mogigu" more effectively improves the knowledge of brushing the teeth of elementary school students.
Based on the effectiveness test results it is known that online media "mogigu" is more effective than phantom media in knowing the changes in students' yearning on how to brush their teeth with p-value (0.000<0.05) which means that online media "mogigu" is more effective in influencing students' knowledge of how to brush their teeth, because at the time of research children were more enthusiastic about counseling when using online media "mogigu" and well receivable by students. This medium offers more interesting and non-monotonous counseling, counseling using this medium offers motion, image and sound compared to counseling using phantom that uses only the voice of counseling, because this medium is relatively new some students have a great curiosity about the content of the video and see the video until it is finished seriously. This is supported by research Muthia, Fitriangga, Syarifah, & Yanti (2016), the senses that channel a lot of knowledge into the brain are the eyes (approximately 75% to 87%), while 13% to 25%, human knowledge is obtained and channeled through other senses. The media should be able to stimulate or enter information through various senses. The more stimulated the information will be. Online media "mogigu" provides stimulation through the eyes and ears. The combination of information channels through the eyes that reach 75% and ears 13% will provide good enough stimulation so as to provide optimal results, as well as research Muthia et al. (2016) states counseling that is interesting and involves more senses will increase one's knowledge.

Conclusion and Suggestion
Based on the results of research on the effectiveness of counseling brushing demonstrations using phantom and online media "mogigu" against knowledge on how to brush their teeth in students of SDN 01 and SDN 04 Klambu Grobogan District in 2020 can be concluded that differences in the value of knowledge on how to brush your teeth before and after counseling using phantom media. There are differences in the value of knowledge on how to brush your teeth before and after counseling are given using online media "mogigu". This study online media "mogigu" was more effective compared to phantom media in influencing students' knowledge of how to brush their teeth with a significant score of 0.000 (p<0.005).
