Abstract:Laboratory testing plays a crucial role in supporting patient diagnosis and monitoring; therefore, accurate and precise results are essential through the implementation of quality control (QC). Potassium level testing is…
one of the key parameters requiring robust quality control because it is closely linked to patients’ clinical conditions. This study aims to analyze the implementation of QC in potassium level testing using the EasyLyte device at the Kasih Ibu Hospital Laboratory in Surakarta. The research method used was quantitative descriptive with an observational approach using secondary data from QC results for the period from September to November 2025. Analysis was performed by calculating the mean, standard deviation (SD), coefficient of variation (CV), and evaluating the Westgard rules. The results showed that the CV values for normal and abnormal controls were within acceptable limits (≤5%), and no violations of any Westgard rules were found. This indicates that the test results have good precision and there are no deviations, either random or systematic. Overall, the analytical system is in control and the instrument performance is stable. Thus, potassium testing using the EasyLyte instrument meets quality requirements and is suitable for use in laboratory services, while still requiring QC monitoring as well as routine maintenance and calibration.

erikan dengan tujuan agar ketersediaan listrik dapat terpenuhi, serta membantu pelanggan yang kurang mampu dan masyarakat yang belum terjangkau pelayanan PT. Berdasarkan hasil evaluasi BKF dengan German International Cooperation (GIZ) terhadap subsidi listrik yang diberikan kepada kelompok pelanggan R1-450 VA dan R1-900 VA yang berlaku saat ini menunjukkan subsidi listrik tidak tepat sasaran, karena 5,9 juta pelanggan R1-450 VA dan 14,4 juta pelanggan R1-900 VA adalah kelompok rumah tangga yang telah mampu karena termasuk dalam pengeluaran per kapita lebih dari Rp.1 juta per bulan. Guna mengurangi risiko salah sasaran tersebut, perlu dilakukan klasifikasi dalam pemberian subsidi listrik berdasarkan kriteria-kriteria tertentu yang telah menjadi standar di PT. PLN menggunakan data mining dengan metode decision tree. Berdasarkan evaluasi dan hasil pengujian bab sebelumnya dengan dataset 50 data, 70 data dan 100 data produksi yang telah dilakukan, maka hasil pengukuran Confusion Matrix dalam penerapan data mining untuk memprediksi target Desa Tebara dengan metode Decision Tree (Algoritma C4.5) pada pengujian 50 data menghasilkan akurasi 74%, precision 60% dan recall 83,33%. Pada pengujian 70 data menghasilkan akurasi 81,43%, precision 76,92% dan recall 74,07%. Pada pengujian 100 data menghasilkan akurasi 82%, precision 76,67% dan recall 67,65%. Jadi untuk data uji lebih banyak akan menghasilkan akurasi yang lebih tinggi.

ese issues by providing educational assistance. However, in its implementation, the selection of PIP recipients at IT Al-Ikhsan Private Junior High School is still inaccurate. This research aims to classify the eligibility of PIP recipients using the Naive Bayes method. This method is applied to student data from the school's Dapodik in 2024 which consists of 265 students. The data is processed through CRISP-DM data mining stages, namely Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, and Deployment. As a result, the Naive Bayes model showed an accuracy of 92.31% with a precision value for the “Yes” class of 89%, recall 100%, and F1-score 94%. In conclusion, variables such as means of transportation, KPS and KIP recipients, parents' income, and distance from home to school affect the eligibility of PIP recipients.

facilities, infrastructure, and public utilities through the principle of mutual cooperation. BSPS recipients must meet several criteria, such as income, house ownership status, house size, floor type, wall type, roof type, and water source. To address issues based on these criteria, Data Mining techniques using the Naive Bayes method were employed. This study utilized a dataset of BSPS recipients in Air Genting Village, Air Batu Sub-district, comprising 88 samples. The classification results from applying Naive Bayes yielded a precision value of 84%, a recall value of 81%, an F1-score of 82%, and an accuracy of 81%. The objective of this research is to facilitate the classification of eligible and rightful recipients of government assistance in the form of BSPS. The results of this study are expected to provide an alternative solution in determining BSPS recipients in Air Genting Village, Air Batu Sub-district
Abstract:This study aims to comprehensively examine the influence of the madrasah principal’s leadership on teacher professionalism in guiding students at MIN 2 Pekanbaru, positioning educational leadership as a key element that…
t determines the quality of pedagogical practice. The investigation focuses on three main questions, namely the characteristics of the principal’s leadership, the level of teacher professionalism, and the extent to which leadership contributes to the effectiveness of student guidance. The novelty of this research lies in the integration of instructional, managerial, and entrepreneurial leadership concepts with teachers’ pedagogical and professional competencies, resulting in a more holistic understanding of the mechanisms through which leadership influences the guidance process that requires accuracy in planning, precision in implementation, and rigor in evaluation. The findings reveal a positive and significant relationship between the principal’s leadership and teacher professionalism, with a contribution of 61.1%, indicating that the majority of improvements in teacher professionalism are shaped by the quality of leadership practiced. Supportive and participatory leadership, reinforced by continuous academic supervision, is proven to enhance teachers’ capacities, strengthen work motivation, and create a professional environment conducive to effective student guidance. These outcomes demonstrate that the effectiveness of guidance is not solely influenced by individual teacher competence but also by leadership structures that direct, facilitate, and optimize educator performance systematically. This study concludes that the madrasah principal holds a central role as a driver of improved guidance quality through the application of visionary, adaptive, and human-resource-oriented leadership, whose implications may serve as a basis for formulating strategies to enhance teacher competence and strengthen educational leadership models within madrasah institutions.

lam memprediksi risiko diabetes berdasarkan dataset medis yang berisi berbagai fitur seperti usia, berat badan, kadar gula darah, tekanan darah, dan riwayat keluarga. Metode ini dipilih karena kemampuannya dalam mengolah data dengan asumsi independensi antar variabel. Pada penelitian menggunakan metode Naive Bayes menunjukkan bahwa memiliki capaian tingkat akurasi sebesar 83.75% dengan precision untuk kelas "Yes" sebesar 86.47% dan recall sebesar 93.50%, yang menandakan performa yang cukup baik dalam mendeteksi pasien diabetes. Namun, performa model dalam mendeteksi pasien non-diabetes perlu ditingkatkan mengingat recall untuk kelas "No" hanya mencapai 51.35%. Hasil ini menunjukkan bahwa Naive Bayes adalah metode yang sederhana namun efektif untuk memprediksi diabetes, dan dapat dikembangkan lebih lanjut untuk membantu pengambilan keputusan medis secara lebih akurat.
