The occurrence of scorch during the production of flexible polyurethane is a significant issue that negatively impacts foam products' resilience and generally jeopardizes their integrity. The likelihood of foam product failure can be decreased by optimizing production variables based on machine learning algorithms used to predict the occurrence of scorch. Investigating technology is required because prevention is the best approach to dealing with this problem. Hence, machine learning algorithms were trained to predict the occurrence of scorch using the thermodynamic profile of polyurethane foam, which is made up of recorded production variables. A variety of heuristics algorithms were trained and assessed for how well they performed, namely XGBoost, Decision trees, Random Forest, K-nearest neighbors, Naive Bayes, Support Vector Machines, and Logistic Regression. The XGboost ensemble was found to perform best. It outperformed others with an accuracy of 98.3% (i.e., 0.983), followed by logistic regression, decision tree, random forest, K-nearest neighbors, and naïve Bayes, yielding a training accuracy of 88.1%, 66.7%, 84.2%, 87.5%, and 67.5% respectively. The XGBoost was finally used, yielding 2-distinct cases of non(occurrence) of scorch. Ensemble demonstrates that it is quite capable and is an effective way to predict the occurrence of scorch.

The learning of physics, particularly mechanics, poses significant challenges for high school students. Concepts such as Newton’s laws, energy, and three-dimensional vectors are often difficult to grasp using traditional teaching methods. Virtual Reality (VR) has emerged as a promising solution by providing an immersive and interactive learning environment. This study aims to evaluate the effectiveness of VR-based learning media in enhancing students’ understanding of physics concepts, with a specific focus on mechanics. An experimental design was employed, consisting of two groups: an experimental group using VR for learning and a control group receiving traditional instruction. Pre-test and post-test assessments were used to measure the improvement in students' conceptual understanding of physics. The findings indicate that students in the experimental group demonstrated a significant improvement in their understanding of complex physics concepts, such as projectile motion, force, and Newton’s laws, compared to the control group. Students in the experimental group also exhibited higher levels of engagement and motivation, with VR's immersive nature encouraging active participation in learning. The study concludes that VR is an effective tool for enhancing students’ comprehension of abstract and complex physics concepts, improving their visualization and problem-solving skills. Furthermore, VR-based learning provides students with opportunities to conduct virtual experiments and simulations that may not be possible in traditional classroom settings. The implications of this study suggest that VR should be integrated into the physics curriculum to improve learning outcomes, especially in schools with access to the necessary technology. Educators and curriculum developers are encouraged to explore VR’s potential in fostering a more engaging and effective physics education.

Hypertension is defined as persistent blood pressure with a systolic pressure ≥140/90 mmHg. Hypertension is one of the risk factors that most influences the incidence of heart disease, blood vessels and stroke. Hypertension often shows no symptoms, so it is only realized when it has caused organ disorders such as heart dysfunction or stroke. One of the causes of hypertension is unhealthy lifestyle factors, one of which is a lack of vegetable consumption which has the risk of causing hypertension. Based on Field Learning Practice (PBL) 1 activities, namely community diagnosis in Citangkolo Hamlet, Kujangsari Village, Langensari District, Banjar City, in 2023, a priority health problem was found, namely hypertension, with the number of sufferers reaching a percentage of 54% of the total 231 people. This is due to the lack of vegetable consumption in the community. Based on this problem, PBL 2 activities were carried out, by carrying out innovative intervention activities for the SI ELNINO program (Alternative Intervention for Citangkolo Hypertension Reducing Plants) which was carried out so that people would pay more attention to consumption patterns by planting pak choy and celery vegetables as a form of control, namely reducing the blood pressure of hypertension sufferers. . This activity is carried out in the form of counseling and providing education, Training of Trainers, and planting by empowering the Women Farmers Group (KWT) with a vegetable planting movement. This activity was attended by posbindu cadres, KWT, and the Citangkolo hamlet community. Through outreach activities there is a significant increase in public knowledge regarding hypertension as proven by the results of the pretest and posttest with a p-value <0.001. So this activity has succeeded in increasing the knowledge of the Citangkolo hamlet community regarding hypertension.

This research was conducted as a response to students' low interest in learning in English subjects at Al Amin Islamic Middle School, North Cikarang, Bekasi Regency. Several factors that cause this low interest include the lack of attractiveness of the material, monotonous teaching methods, and the lack of connection between English language material and students' daily lives. The impact is a decrease in students' interest in these subjects, which can affect their interest in learning. In an effort to increase students' interest in learning, the Problem Based Learning (PBL) learning model is used, where the teacher gives students ample opportunities to determine problem topics that are relevant to the learning material, even though the teacher has prepared the material that will be discussed in the lesson. The learning process is focused on students' abilities to solve problems systematically and logistically. This research uses a qualitative approach with descriptive methods. Through observation, interviews and documentation, the research results show that the application of the PBL learning model at Al Amin Islamic Middle School, North Cikarang, Bekasi Regency can increase students' interest in learning. English teachers who use the PBL model get good responses from students, where students are active in the teaching and learning process, ask questions actively, and are able to answer questions well and appropriately during discussions. The PBL learning model also encourages students to be more diligent in doing their assignments and provides high motivation to learn. Students find it easier to solve problems and are able to apply the knowledge they have.

To improve the quality of the student learning process by increasing the quality of teachers' professional abilities, all teachers must go through a learning process that makes it possible to find and solve learning problems in their respective classes based on the principles of Classroom Action Research (PTK). Classroom Action Research is carried out with the aim of improving or enhancing student learning activities and achievements. PTK is an activity carried out to find out problems that arise in the classroom when the teacher is interacting with students in carrying out the teaching and learning process. PTK is research carried out by class teachers through self-reflection with the aim of improving teacher performance, so that the quality of learning increases (Mills, Geoffrey E, 2000, Schmuch, A. Richard, 1997) which can be seen in the percentage of students' success in completing the exercises systematically. verbally and in writing. In the learning process, learning means an activity carried out by the teacher and students together. The essence of the learning is the process of giving and receiving and ends with an evaluation which is deliberately carried out by the teacher to find out how far the students' level of understanding is

One of the efforts to overcome teacher problems in learning is by educational supervision. Supervision is guidance in the form of guidance or guidance towards improving the educational situation in general and improving the quality of teaching and learning. Supervision is carried out by the Principal (supervisor) whose role is to supervise teaching and learning activities, teacher performance etc. The purpose of supervision is to develop better situations to train the learning process and improve the teaching profession. The study was conducted because researchers wanted to get a better understanding of a special case This research reveals specifically about the implementation of teaching supervision and teacher performance in the learning process of Islamic religious education in MTSN 2 Bengkalis. Based on the entire series of analysis and discussion of data, it can be concluded that the implementation of principal supervision of the performance of Islamic religious education teachers in MTSN 2 Bengkalis is The planning of principal supervision is carried out in a planned, systematic and continuous manner. At this stage the principal determines the name of the teacher to be observed, forms a determination of the time for the implementation of the observation time, compiles an observation grid and determines whether the class observation is known to the teacher or not, this is based on an agreement between the principal and the Islamic religious education teacher. In the implementation of supervision, the principal's attitude did not interfere with the process of learning Islamic religious education in the classroom even the principal at the end of class hours gave motivation to students to continue learning diligently. In the follow-up stage, the results of supervision are discussed jointly between Islamic religious education teachers and school principals who discuss teacher deficiencies in teaching in the hope that in the future teachers can improve them.
