php/bikes INTRODUCTION An emergency measure known as cardiopulmonary resuscitation (CPR) is basic life support (BHD) that aims to free the airway, assist breathing, and maintain blood circulation without the use of assistive devices.
Some steps to identify Basic Life Support (BHD) actions include identifying cardiac arrest, palpating the pulse, chest compressions, freeing the airway, breathing, and correct positioning.
(Romadoni et al.
, 2.
According to research (Nirmalasari & Winarti, 2.
, emergencies can happen anytime, to anyone, and anywhere.
Cardiac arrest is one of the most common types of emergencies (AHA, 2.
Apart from causing organ damage, cardiac arrest also experiences a high incidence rate in the hospital or outside the hospital or also called Out Of Hospital Cardiac Arrest (OHCA) (Pawiliyah et al.
, 2.
The success of helping patients who experience emergency conditions is not only determined by the quality of emergency services in the hospital but also the success of the help provided outside the hospital (Susilo et al.
, 2.
everyday life, it is also often found that someone suddenly loses consciousness or finds victims on the road facing this what must be done is to provide basic life support (BHD), which is a series of first attempts to restore respiratory and / or circulatory function in someone who has stopped breathing and / or cardiac arrest, but because they are unfamiliar with it, they are confused about what should be Resuscitation must begin when it is known that the victim is suffering from respiratory arrest and cardiac arrest (Fauzan et al.
, 2.
When finding victims of cardiac arrest outside the hospital, the first thing to do is to help, so lay people must have knowledge of basic life support.
But there are still many ordinary people or students who still do not know about first aid for victims of cardiac arrest.
(Year et al.
, 2.
Basic life support (BHD) knowledge is a knowledge and skill.
Basic life support in this case cardiopulmonary resuscitation (CPR), which is very important in the survival of victims of cardiac arrest.
This means that there is a need to increase the number of knowledge (BHD) in the (Triwianti, 2.
Knowledge is also closely related to education, because knowledge is obtained through formal and informal education, therefore the community and including adolescents, really need to have the knowledge and ability to provide assistance and can become first responders in providing assistance.
It is concluded that the survival of cardiac arrest people will increase with the provision of basic life support (Pawiliyah et al.
, 2.
Adolescents are one of the parts of society that also really need to know about first aid when finding victims of cardiac arrest.
Adolescents are expected to be first responders, or lay people who first provide help at the scene, because they grow in body size, strength, psychology, reproductive ability, are easily motivated, and learn quickly.
Adolescents who attend secondary level schools, i.
high school or vocational school, may exhibit these characteristics.
However, many students or young laypeople do not e-ISSN : 2807-2448 com/index.
php/bikes know basic life support.
This is due to the lack of information and publicity efforts regarding basic life support in the (Susilo et al.
, 2.
Students' knowledge can be seen from previous data, namely, based on the results of Wulandari's .
research (Susilo et al.
, 2.
on high school students' knowledge of basic life support, showing that 76% of respondents have insufficient knowledge in providing basic life support to victims of cardiac arrest or respiratory arrest and accident victims, 17% have sufficient knowledge and the remaining 7% have good knowledge in basic life support.
Results (Program et al.
, 2.
Knowledge of basic life support in students of SMK 5 Banjarmasin as much as 38% is still lacking.
This is due to the fact that most of the students have not attended the lesson and have never heard of BHD.
Data that researchers conducted at SMK Arinda Palembang, obtained data on the number of class XI students in the 2021-2022 school year as many as 60 The results of the preliminary study on April 06, 2022, researchers interviewed 12 respondents who were asked about first aid in cases of sudden cardiac arrest at SMK Arinda, the results concluded that students did not know much about basic life support (Nadela Prianis Utami et al.
, 2.
Basic life support that is not provided quickly can lead to many events outside of healthcare.
However, it is inevitable that these events cannot be prevented by medical personnel and ordinary people, including high school Researchers have information about victims who experience cardiac arrest or respiratory arrest based on previous The American Heart Association (AHA) says the latest statistics based on the Resuscitation Guidelines and the results of the Cardiac Epistry Consortium show that the rate of cardiac arrest across the country remains high.
In 2013, a total of 359,400 cardiac arrests occurred outside of hospitals in the United States.
This is in contrast to the 382,800 cardiac arrests that occurred in 2012.
(Fatmawati et al.
, 2.
According to data collected by the World Health Organization (WHO) in 2015, 70% of deaths in the world were caused by non-communicable diseases (NCD.
, with 39.
5 million people dying.
Heart and vascular diseases also accounted for 45% of the total deaths due to NCDs, which was 17.
7 million people out of 39.
5 million people.
(Triwianti.
According to previous studies, the incidence of cardiac arrest in the United States reaches 250,000 people every year, with 95% predicted to die before arriving at the hospital.
In Indonesia, there are no precise statistics on the number of cardiac arrests, but an estimated 10,000 people die each year.
Cardiac arrest, also known as cardiac arrest, is a life-threatening emergency condition that can result in death if not treated promptly.
It occurs at home and elsewhere when people are on the move (Kistan & Najman, 2.
In Indonesia alone, there is no clear data on how many people experience cardiac arrest on a daily basis or outside the hospital.
However, it is estimated that there are around 10,000 people in the e-ISSN : 2807-2448 com/index.
php/bikes country every year, which means 30 people experience cardiac arrest every The highest number of deaths are experienced by people with coronary heart disease.
It is estimated that by 2030, the number of deaths caused by vascular heart disease, particularly coronary heart disease and stroke, will increase to 23.
(Berutu & Silalahi, 2.
Based on these data, knowledge of Basic Life Support (BHD) is very important to be known by ordinary people or teenagers.
Knowledge of basic life support (BHD) or Basic Life support (BLS) is very important for ordinary people because emergencies can be found anywhere and anytime (Trinurhilawati et , 2.
One of the efforts to increase knowledge of basic life support is to increase knowledge to lay people or adolescents about basic life support, so that they are able to provide assistance to victims of respiratory arrest and cardiac arrest (Oktafiani & Fitriana, 2.
Research (Triwianti, 2.
The level of knowledge is a component that influences a person's behavior.
Knowing, which occurs after someone perceives something, is called knowledge.
Most human knowledge is obtained through the ears and eyes.
Education is also very close to knowledge because knowledge is obtained through formal and informal (Pawiliyah et al.
, 2.
Therefore, interested in examining teenage children to become respondents, especially at the level of children aged 15-16 years and over or can be called high school / vocational school age.
(Program et al.
However, students are still unfamiliar due to the lack of information and publication efforts about basic life support in the community (Susilo et al.
, 2.
So, education or counseling is a way to provide Health education is an effort or activity to assist people, groups, and communities in gaining the knowledge, attitudes, and skills needed to lead a healthy lifestyle.
(Year et al.
, 2.
One of the results of the effect of counseling is the knowledge of students at SMK Kesehatan Sentra Medika Medan Johor before the BHD simulation the majority of their knowledge is lacking, which is 55.
5%, the knowledge of students after the BHD simulation the majority of their knowledge is good, which is 77.
There is an effect of health education about basic life support (BHD) on the level of knowledge (Syapitri et al.
, 2.
The results of an initial survey conducted by researchers on January 11, 2024 showed that 5 students at SMA Santo Thomas 1 Medan had never received or provided basic life support because they did not know or understand about basic life support.
According to the researcher's observation, none of the students in the school knew or understood basic life support.
Based on the above background, the researcher is interested in conducting research on the effect of health education on basic life support (BHD) on the level of knowledge of Class XI Students At Santo
Thomas 1 Medan SMA in 2024
RESEARCH METHODS
The research design used was a preexperimental design.
The research design used was a one-group pre-post test e-ISSN : 2807-2448 com/index.
php/bikes This method involves one group of subjects to reveal a causal relationship.
Before the intervention, the subject group is observed, and then observed again after the intervention.
The treatment group will receive BHD intervention in the form of material explanation and lecture.
The population in this study were grade XI students at SMA Santo Thomas 1 Medan.
The total number of grade XI is 432 students.
Each class, starting from XI MB 1-XI MB 12 amounted to 36 students/class.
This study took samples from SMA Santo Thomas 1 Medan class XI students, taken through Probability sampling technique with Systematic sampling If a list of required subjects is available, this systematic sampling can be Where the population N= 432 and n=36 samples were selected.
Thus, the sample selected is based on the number of multiples of 12, namely sample number

So the number of respondents per class is 3 people.
The impact on the dependent is manipulated by the researcher.
The factor observed and measured as the dependent variable in this study is the knowledge of class XI students at SMA Santo Thomas 1 Medan about basic life support before and after counseling.
The instrument in this study used a questionnaire made by researchers (Rahmatullah, 2.
which contained 20 questions with multiple choices, covering students' knowledge of BHD, namely:
Definition of basic life support (BHD).
Basic life support (BHD) objectives Indications for basic life support (BHD) Basic life support (BHD) management After all the data is obtained, it will be given an assessment and scoring.
For the correct answer will be given a score of 5 and for the wrong answer given a score So that the minimum score obtained by the respondent is 0, while the maximum score obtained by the respondent is 100.

this is due to students who have not been exposed to material about basic life support.
This is supported by Fitri's research .
which states that someone who has never been given BHD material is less knowledgeable about BHD.
Students who lack information or have never been given health education about BHD is one of the factors that can affect the knowledge of respondents (Program et al.
, 2.
This is in accordance with previous research related to Cardiopulmonary Resuscitation at SMK N 1 Bawen that 71.
respondents before being given a Basic Life Support (BHD) education intervention had insufficient knowledge, this could be due to the absence of specific information they received about daily Basic Life e-ISSN : 2807-2448 com/index.

Lack of knowledge about everyday emergencies and their management can be due to the lack of information obtained.
Theory says that information obtained from either formal or non-formal education aims to improve and develop academic, social, and personal competencies or abilities in the fields of knowledge, skills and attitudes.
The lack of knowledge is evidenced when researchers ask questions related to the definition of basic life support, overall students still do not know and answer incorrectly, due to a lack of information and have never received learning about basic life support.

Changes in student knowledge were influenced by age and the learning methods used.
Young enough age tends to be younger and faster in terms of reasoning power and capacity to capture the information provided.
There are also students who still have sufficient knowledge due to the lack of student focus in paying attention to the interventions provided by researchers regarding basic life support.
This is supported by Susilo et al .
explained that not only counseling affects behavior, but it is also influenced by the ability to perceive the objects conveyed during counseling through the five human senses.
Sensing can produce knowledge that is influenced by the intensity of attention to the perception of objects and most human knowledge is obtained through the eyes and ears.

In previous studies related to increasing knowledge of basic life support out-of-hospital resuscitation to high school students.
From the post-test results, it was found that the participants' knowledge changed after being given BHD health education with audiovisual media to 60 high school students, indicating that respondents had a good level of knowledge about BHD with an average BHD knowledge of 84.
Significant changes in knowledge in participants This shows that the knowledge of high school students has almost entirely increased after being given an intervention because of health education through audiovisual media so that high school students can know how and the steps of BHD.
(Program et al.
Previous research related to basic life support (BHD) knowledge of PMR members of SMK Swadaya Temanggung, from 24 respondents, it was proven that the level of knowledge before being given BHD training was in the category of good knowledge of 2 students .

%).
After being given BHD training, the category of good knowledge increased by 18 students .

2%).
The thing that influences the increase in knowledge of PMR members is the provision of training using lecture and question and answer methods so that PMR members understand the correct basic life support information (Arafat et al.
, 2.
Previous research related to basic life support counseling at SMK Arinda Palembang the results of research that has been conducted to 60 respondents.
The results showed that the level of knowledge of respondents after being given health education about BHD was 78.
with a standard deviation of 442, the minimum value was 46 and the maximum value was 100.
From the estimation it is believed that the knowledge before being given health education is between 75.
191 to 81.
Based on the results of the research conducted, the success rate of health education in increasing knowledge is quite high so that researchers argue that health education can be a good alternative in increasing knowledge about basic life (Nadela Prianis Utami et al.
Previous research related to basic life support (BHD) knowledge at SMAN 2 Muara Enim The results of the study obtained before being given BHD health education with audiovisual media to 60 high school students showed that respondents had a level of knowledge with a poor category regarding BHD with an average BHD knowledge of 55.
63, after being given BHD health education with audiovisual media to 60 high school students showed that respondents had a level of knowledge with a good category regarding BHD with an average BHD knowledge of 84.
Efforts to increase knowledge require a method that is fun and not boring so that students are interested in learning, one method that e-ISSN : 2807-2448 com/index.

According to Mi's theory .
health education is one of the efforts that can be given in increasing knowledge.
One of the factors that influence a person's behavior is the level of knowledge.
According to Darsini et al .
knowledge is the result of knowing, and this occurs after people perceive a certain Sensing occurs through the five human senses, namely the senses of sight, hearing, smell, taste and touch.
Most human knowledge is acquired through the eyes and ears .
eeing and hearin.
Knowledge is also very close to education, because knowledge is obtained through formal and informal education.
The learning media used in this study to determine the level of student knowledge about basic life support is using lecture and audiovisual methods.
According to Nurmala .
this lecture and audiovisual method is suitable for use in large groups of about >15 people.
using lecture and audiovisual methods, students become less bored and more easily understand in receiving health education about basic life support (BHD).
The results of this study are in accordance with research conducted by Fatimah.
Selviana.
Otik, & Linda .
and Wardani.
Arif, and Galih .
where audiovisual media is effective in increasing respondents' knowledge and skills and is also able to stimulate many senses of learning, namely the sense of vision and the sense of hearing.
Research conducted by Fauzan .
states that watching videos that contain sound and movement can increase a person's ability to understand learning.
The more often a person is exposed to BHD, it will improve his ability in terms of BHD both aspects of knowledge and skills (Fauzan et al.
, 2.
So in conducting this study, researchers conducted interventions 3 times a meeting in 3 weeks.
So that in providing continuous intervention, the respondent's knowledge is good.
This is in line with research by Setiawan .
which explains that after being given basic life support counseling using lecture and audiovisual methods, respondents experienced an increase in knowledge due to the provision of Efforts knowledge require a method that is fun and not boring so that people are interested in learning, one method that can be used is lectures and audiovisuals (Program et al.
, 2.
Overall this research is supported by previous research that students as lay people can perform first aid on anyone in an emergency situation, especially on people who experience cardiac arrest and respiratory arrest which are generally found by lay people.
The role of the layperson as the first finder of the victim is very influential.
The role of ordinary people in this case high school adolescents is very important to increase one's life expectancy through knowledge and ability to perform Basic Life Support (BHD), therefore information in the form of health education, simulation of Basic Life Support needs to be carried out e-ISSN : 2807-2448 com/index.
