Phishing is a crime that uses social engineering techniques, both in deceptive statements and technically, to steal consumers' personal identification data and financial account credentials. With the new Phishing machine learning approach, websites can be recognized in real-time. K-Nearest Neighbor(KNN) and Naïve Bayes (NB) are popular machine learning approaches. KNN and NB have their own strengths and weaknesses. By combining the two, deficiencies can be covered. So this study proposes to combine K-Nearest Neighbor with Naïve Bayes to classify phishing websites. Based on the results of the accuracy test of the combination of KNN with k=8 and Naïve Bayes, a maximum accuracy of 93.44% is produced. This result is 6.25% superior compared to using only one classifier.

Convolutional neural network (CNN) is a deep learning (DL) model that has significantly contributed to medical systems because it is very useful in digital image processing. However, CNN has several limitations, such as being prone to overfitting, not being properly trained if there is data duplication, and can cause unwanted results if there is an imbalance in the amount of data in each class. Data augmentation techniques are used to overcome overfitting, eliminate data duplication, and random under sampling methods to balance the amount of data in each class, to overcome these problems. In addition, if the CNN model is not designed properly, the computation is less efficient. Research has proved that data augmentation can prevent or overcome overfitting, eliminating duplicate data can make the model more stable, and balancing the amount of data makes the model unbiased and easy to learn new data as evidenced through model evaluation and testing. The results also show that the custom convolutional neural network model is the best model compared to ResNet50 and VGG19 in terms of accuracy, precision, recall, F1-score, loss performance, and computation time efficiency

Diabetes Mellitus is a hazardous disease, and according to the World Health Organization (WHO), diabetes will be one of the main causes of death by 2030. One of the most popular diabetes datasets is PIMA Indians, and this dataset has been widely tested on various machine learning (ML) methods, even deep learning (DL). But on average, ML methods are not able to produce good accuracy. The quality of the dataset and features is the most influential thing in this case, so deeper investment is needed to examine this dataset. This research will analyze and compare the PIMA Indians and Abelvikas datasets using the Random Forest (RF) method. The two datasets are imbalanced, in fact, the Abelvikas dataset is more imbalanced and has a larger number of classes so it is be more complex. The RF was chosen because it is one of the ML methods that has the best results on various diabetes datasets. Based on the test results, very contrasting results were obtained on the two datasets. Abelvikas had accuracy, precision, and recall, reaching 100%, and PIMA Indians only achieved 75% for accuracy, 87% for precision, and 80% for the best recall. Testing was done with 3, 5, 7, 10, and 15 tree number parameters. Apart from that, it was also tested with k-fold validation to get valid results. This determines that the features in the Abelvikas dataset are much better because more complete glucose features support them.

Skin is the largest organ in humans, it functions as the outermost protector of the organs inside. Therefore, the skin is often attacked by various diseases, especially cancer. Skin cancer is divided into two, namely benign and malignant. Malignant has the potential to spread and increase the risk of death. Skin cancer detection traditionally involves time-consuming laboratory tests to determine malignancy or benignity. Therefore, there is a demand for computer-assisted diagnosis through image analysis to expedite disease identification and classification. This study proposes to use the K-nearest neighbor (KNN) classifier and Gray Level Co-occurrence Matrix (GLCM) to classify these two types of skin cancer. Apart from that, the average filter is also used for preprocessing. The analysis was carried out comprehensively by carrying out 480 experiments on the ISIC dataset. Dataset variations were also carried out using random sampling techniques to test on smaller datasets, where experiments were carried out on 3297, 1649, 825, and 210 images. Several KNN parameters, namely the number of neighbors (k)=1 and distance (d)=1 to 3 were tested at angles 0, 45, 90, and 135. Maximum accuracy results were 79.24%, 79.39%, 83.63%, and 100% for respectively 3297, 1649, 825, and 210. These findings show that the KNN method is more effective in working on smaller datasets, besides that the use of the average filter also has a significant contribution in increasing the accuracy.

Education is basically a conscious effort to grow and develop the potential of human resources (HR), especially for students by providing encouragement and providing good facilities through learning activities. In addition, each individual must have the ability and willingness to learn so that the learning objectives can be achieved. The achievement of each individual from each learning process is called learning achievement. As for one of the supporting factors that are dominant in influencing learning achievement is the intelligence of each individual student. The purpose of this study is to find out how much influence the level of intelligence has on learning achievement, especially in the field of Islamic religious education (PAI) at MAN 1 Sukabumi City. The research method used is survey method with correlational analysis. Based on the results of the data analysis performed, it was found that intelligence has a significant effect on learning achievement. This is evidenced by the t count of 7.811 with a significance level of 0.01 and 0.05. Based on the data analysis test, it was also found that F was 61.011 with a significance value of 0.01 (p <0.05). This shows that intelligence has a significant influence on student achievement. Apart from the F value, an R square value of 0.592 is also obtained, which means that 59.2% of student achievement in PAI is influenced by the level of intelligence, while the remaining 40.8% is influenced by other factors such as motivation or learning environment. Then the results of the research conducted can be concluded that the level of intelligence has a significant effect on student achievement in PAI either partially or simultaneously. The other supporting factors are motivation, socioeconomic, class climate or learning methods which support student achievement, especially in Islamic Religious Education.

This research is motivated by facts in the field showing that social studies teachers are still more oriented towards assignments and students' understanding of learning material without considering the formation of student character as a learning effect, so that learning material is less affected by students' attitudes and personalities in shaping interactions between teachers and students. This makes students tend to be busy or not pay attention when the teacher is explaining, during the learning process in the classroom. Therefore, these constraints certainly need a solution so that the teaching and learning process can be channeled properly, an IPS teacher really needs to use a learning strategy that is appropriate to the material to be conveyed and is also in accordance with the IPS teacher's strategy in instilling social values. The formulation of the problems in this study are: 1) What is the social studies teacher's strategy to instill social values in social studies learning for class VII students at SMPN 1 Purwoasri? 2) What are the supporting and inhibiting factors for social studies teachers in carrying out strategies for instilling social values in class VII students at SMPN 1 Purwoasri? 3) What are the results of the IPS teacher's strategy in instilling social values in class VII at SMPN 1 Purwoasri? The objectives of this study are: 1) To find out the social studies teacher's strategy to instill social values in social studies learning for class VII students at SMPN 1 Purwoasri. 2) To identify the supporting and inhibiting factors of social studies teachers in carrying out strategies for instilling social values in class VII students at SMPN 1 Purwoasri. 3) To find out the results of the social studies teacher's strategy in instilling social values in class VII at SMPN 1 Purwoasri. The research method used is a qualitative method and this research is descriptive in nature. This research is sourced from primary data and secondary data. Data collection techniques in the form of observation, interviews and documentation. Then the data analysis technique in this study refers to the Miles and Huberman model. Checking the validity of the data, namely observation persistence, triangulation, and peer checking. The results of this study indicate that: 1) The social studies teacher's strategy in instilling social values possessed by students is through several ways, namely exemplary and continuous reprimand and habituation patterns. To instill social values in students, the teacher instills an attitude of honesty, discipline, tolerance, mutual cooperation, courtesy, confidence and responsibility (an attitude of daring to accept consequences, being able to carry out individual tasks properly, not blaming others, and always keeping promises). to students. 2) Factors that support the social studies teacher's strategy in instilling social values in students are a comfortable learning environment, there are rules in the class that are obeyed, and there is a dominant role of the teacher. On the other hand, the inhibiting factors of the social studies teacher's strategy in instilling social values in students are the teacher being late, the lack of monitoring of regulations, and the influence of friends. 3) The results of the social studies teacher's strategy in instilling social values in class VII students at SMPN 1 Purwoasri include social awareness, multicultural understanding, and social involvement which are in good condition.

This research is motivated by the lack of students' ability to compose observation report texts. Based on interviews conducted with previous Indonesian subject teachers, it is known that the cause of the low ability to compose observation report texts is because students find it difficult to express ideas, provide understanding and object details, choose the right diction, spelling and punctuation. Likewise interviews with several students, they stated that the text material of the observation report was quite difficult plus the learning that had been carried out was not interesting. Therefore, to improve the skills of compiling observation report texts, the Discovery learning model and the Exploration of the Surrounding Nature (JAS) method are used. Using Classroom Action Research (CAR), which is often used to improve learning processes and outcomes. The research subjects were class VII-10 students of SMPN 11 Medan. Based on the results of the description and analysis of the discussion of cycle 1 and cycle II data, students' abilities in the Observation Reports (LHO) material increased by 35%. It can be concluded that students' abilities have increased through the discovery model and the JAS method in compiling the text of the Observation Report (LHO).
