KLASIFIKASI PENYAKIT KULIT BERBASIS SUPPORT VECTOR MACHINE DENGAN EKSTRAKSI FITUR ABCD RULE
Full text linkPenyakit kulit merupakan masalah kesehatan yang signifikan, gejala dari penyakit ini berupa gatal, nyeri, mati rasa, dan kemerahan. Penyakit ini dapat disebabkan oleh beberapa faktor seperti virus, jamur, dan mikroorganisme. Menurut data Dinas Kesehatan Surabaya tahun 2019, prevalensi penyakit kulit dan jaringan subkutan mencapai 4,53%, menjadikannya penyakit terbanyak keenam yang dialami masyarakat. Oleh sebab itu, pada penelitian ini diusulkan sebuah penelitian mengenai klasifikasi penyakit kulit menggunakan Support Vector Machine melalui analisis fitur ABCD Rule. Pada penelitian ini akan dilakukan labeling pada 5 kelas penyakit kulit yang akan digunakan sebagai data latih dan data uji melalui 7 tahapan utama yakni Pengumpulan Dataset Citra Penyakit Kulit, Pre-processing Inpaint Talea, Pre-processing Gaussian Blur dan Normalisasi Mask, Segmentasi Thresholding Otsu Bitwise, Restorasi Kontur, Ekstraksi Fitur ABCD Rule, dan klasifikasi menggunakan Support Vector Machine (SVM). Sebanyak 4 skenario pengujian dilakukan untuk menemukan model terbaik, dimana skenario pengujian melibatkan pengaturan pembagian data yang berbeda, kernel berbeda, dan parameter yang berbeda pada model Support Vector Machine (SVM). Melalui skenario tersebut didapatkan hasil terbaik, yaitu Akurasi sebesar 86,42%, Spesifisitas sebesar 96,60%, dan Sensitivitas sebesar 86,42%. Hal ini menunjukkan bahwa metode yang diusulkan memiliki kinerja yang cukup baik dalam mengklasifikasikan jenis penyakit kulit. Penelitian ini tidak hanya berpotensi dalam meningkatkan diagnosis penyakit kulit secara efisien, tetapi juga mendorong pengembangan sistem deteksi berbasis teknologi untuk mendukung layanan kesehatan kulit yang lebih terjangkau dan andal

Full text linkThe study aimed to describe the numeracy skills of SMPN 18 Samarinda students in working on AKM (Minimum Competency Assessment) questions based on FI (Field Independent) and FD (Field Dependent) cognitive styles. The study used qualitative research methods. The subjects were 30 students of class VIII of SMP Negeri 18 Samarinda, while the object of the study was the students' numeracy skills in solving AKM questions based on cognitive styles. The data collection techniques used included tests and interviews. The data analysis technique was conducted descriptively by determining the average score of the AKM test results. The results indicated that at the cognitive level of understanding, students with FI and FD cognitive styles were able to calculate and solve cognitive questions. At the cognitive level of application, students with FI and FD cognitive styles were able to apply and choose strategies for solving AKM questions. At the cognitive level of reasoning, students with FI cognitive style were able to present and evaluate in solving cognitive questions, while students with FD cognitive style were only able to present.

THE RELATIONSHIP OF SELF-CONFIDENCE WITH THE MATHEMATICAL PROBLEM-SOLVING ABILITY OF JUNIOR HIGH SCHOOL STUDENTS
Full text linkThe purpose of this study is to describe the relationship between self-confidence and mathematical problem-solving ability in finding solutions to linear equations among junior high school students. This study utilizes a qualitative approach with a correlational design. The subjects of this study are the 32 students of class VIII D at SMP Negeri 12 Pontianak. The instruments are used including a self-confidence questionnaire and a test on the ability to solve problems related to linear equations. Data analysis employs the Pearson Product Moment correlation. The data shows that the students of class VIII D have a good level of self-confidence in learning mathematics. The majority of these students also possess good mathematical problem-solving abilities. Based on the calculation of the Pearson Product Moment correlation, the obtained correlation coefficient (r-value) between self-confidence and mathematical problem-solving ability for the students of class VIII D at SMP Negeri 12 Pontianak is 0.366, indicating a low correlation. However, there is a positive and statistically significant relationship between self-confidence and mathematical problem-solving ability, implying that an increase in self-confidence tends to correspond with an improvement in students' problem-solving skills.
PENGARUH PENERAPAN PENDEKATAN RME TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA KELAS VIII SMP
Full text linkThe ability to answer mathematical issues gave pupils the chance to use it to overcome obstacles in everyday life as well as in the fields of mathematics and other sciences. A method known as Realistic Mathematics Education (RME) connected mathematical difficulties to pertinent real-world concerns. The purpose of this study was to ascertain whether the RME approach had an impact on the eighth-grade students at SMP Negeri 03 in Bengkulu City's capacity to solve mathematical problems. A quasi-experimental design with a nonequivalent control group was the study methodology employed. The treatment (X) or learning with the RME approach was applied to the first group, while the other group received conventional learning or no treatment. The sample was chosen using the purposive sampling technique. The study's findings demonstrated that the use of the RME approach affected the students' capacity to solve mathematical problems, as evidenced by a sig. (2-tailed) value of 0.001 significance level (α) = 0.05 based on the independent sample t-test statistical test on the two sample classes. Additionally, the average N-Gain score obtained was 0.40, which was classified as a "moderate" increase in understanding. Thus, it could be concluded that the use of the RME approach had a positive impact on the improvement of students' mathematical problem-solving abilities
