l untuk penanganan yang tepat. Penelitian ini bertujuan untuk membandingkan performa algoritma Naive Bayes dan Random Forest dalam mengklasifikasikan kanker payudara menggunakan dataset Breast Cancer Wisconsin. Metodologi penelitian dimulai dengan pengumpulan data dari dataset Breast Cancer Wisconsin yang terdiri dari 569 sampel dengan 32 atribut. Proses preprocessing data meliputi konversi data dari format nominal ke binominal untuk atribut diagnosis. Implementasi algoritma menggunakan tools RapidMiner dengan pendekatan cross validation (k=10) untuk evaluasi model yang lebih robust. Performa kedua algoritma dibandingkan menggunakan berbagai metrik evaluasi termasuk accuracy, precision, recall, dan analisis confusion matrix. Hasil penelitian menunjukkan bahwa algoritma Random Forest memberikan performa yang lebih unggul dengan tingkat akurasi 94,91% (±5,06%), precision 95,33%, dan recall 93,90%. Sementara itu, Naive Bayes mencapai akurasi 93,51% (±5,30%), precision 93,68%, dan recall 92,67%. Random Forest juga menunjukkan keunggulan dalam mengurangi false positive, dengan hanya 8 kasus dibandingkan 15 kasus pada Naive Bayes. Analisis confusion matrix menunjukkan bahwa kedua algoritma memiliki kemampuan yang baik dalam mengklasifikasikan kasus kanker payudara, meskipun Random Forest menunjukkan performa yang lebih stabil dan akurat. Kesimpulan dari penelitian ini menunjukkan bahwa kedua algoritma efektif untuk klasifikasi kanker payudara, dengan Random Forest menunjukkan keunggulan dalam hal akurasi dan presisi. Hasil ini dapat menjadi pertimbangan dalam pengembangan sistem pendukung keputusan untuk diagnosis kanker payudara, dimana Random Forest dapat menjadi pilihan utama ketika akurasi menjadi prioritas, sementara Naive Bayes tetap menjadi alternatif yang valid ketika kesederhanaan implementasi dan efisiensi komputasi diperlukan.
Abstract:The purpose of this study is to find out and prove how much influence brand image has on the purchase decision of bakery products in CV. Lemona Cake &Bakery Tasikmalaya. This study uses quantitative methods with an associative…
iative approach that is causal aims to determine the influence between independent variables on dependent variables. The population in this study is respondents who have bought bakery products at Lemona Cake &; Bakery Tasikmalaya, while the number of respondents is as many as 97 respondents. In this study using Non Proability Sampling techniques, Non Proability Sampling, namely sample selection with non-probability methods or non-randomly, population elements do not have the same opportunity to be selected as samples. This is done based on the consideration of relatively fast hang times and relatively cheap costs, then the sampling method uses Accidental Sampling, Accidental sampling is a sampling technique based on chance, that is, anyone who accidentally meets the researcher can be used as a sample, if it is considered that the person who happened to meet is suitable as a source of data. From the results of this study shows that the value of t-count obtained is 8.204 and t-table 1.661 it can be seen that t-count is greater than t-table (8.204 > 1.661) so that H0 is rejected and Ha is accepted meaning that the hypothesis is accepted, so it can be explained that brand image has a positive and significant effect on purchasing decisions, with a value I of 0.644 and a value of coefficient of determination (R square) of 0.641 which means the influence of brand image variables (x) on the purchase decision variable (y) is 64.1% while the remaining 35.9% is explained by other factors or variables that are unknown and not included in this study.

ented by Primkoppol and how this system contributes to the improvement of its members' welfare. Employing a descriptive analytical approach, this research delves into the organizational structure, operational mechanisms, and strategies adopted by Primkoppol in executing its functions and objectives. Focusing on the evaluation of management practices, including resource management, profit allocation, and member development programs, this study seeks to identify the keys to success and the challenges faced by Primkoppol in its efforts to enhance member welfare. This analysis is supplemented with secondary data and direct survey results from members to capture their perceptions and experiences regarding the effectiveness of the services provided by Primkoppol. The findings indicate that Primkoppol has implemented various positive initiatives oriented towards improving member welfare, including innovations in financial services, enhancement of product and service quality, and member capacity development through education and training. However, there is also room for improvement, especially in terms of enhancing management transparency, operational efficiency, and adaptation to digital technology. This study concludes that to continue improving its members' welfare, Primkoppol needs to further optimize an adaptive and responsive management system to environmental changes and member needs. Recommendations include improvements in two-way communication between management and members, integration of information technology, and strengthening of institutional capacity.

Learn." A hermeneutic-phenomenological study was conducted with five students in grades 4-5. Data were generated through in-depth conversations and participant observations during a four-week classroom mindfulness program and analyzed through phenomenological reduction and thematic synthesis. The research findings indicate that the unchanging essence, namely "a shift from an anxious mind to a calm mind that opens up space for learning," is expressed through four interrelated themes: perceived emotional calm, sustained attention, easier recall, and positive appreciation of quiet moments. The study concludes that mindfulness is not simply a technique, but a pedagogical way of life that begins with learning; integrating brief, mindful pauses can foster reflective, calm, and independent learners aligned with the Pancasila Student Profile.

trong positive correlation between perceived assignment load and mental health problems. The method of this research used quantitative approach using a questionnaire. The Data was collected from 20 participants. The researchers, analyzed the data using pearson's correlation coefficient JASP to examine the relationship between excessive assignment and mental health condition. Based on the findings, the result showed a significant positive correlation (r = 0.900, p <.001) between excessive assignment and mental health condition, indicating that 81.0% of the variance in students' mental health could be attributed to their perceived workload. Educational institutions should take proactive steps to manage student workloads and provide mental health support services, such as counseling, time management training, and flexible deadlines. Promoting a balanced approach to academic assessment that prioritizes both academic excellence and student well-being is crucial for fostering the success and well-being of English language students. This research limited due to the small sample size and focus on a specific student population. Future research with larger and more diverse samples is needed to further explore the complex relationship between academic demands and student mental health. The findings highlight the urgent need for universities and educators to prioritize student mental health alongside academic achievement. Implementing practical strategies to manage workloads and provide mental health support can promote a more holistic and student-centered educational environment.
