Abstract

Queuing is a waiting line state where a number of entrants are involved to get services from a service providing facility. One example of queuing activities that are common in the community is taking medicine at the Meko Village Health Center. The purpose of this study was to obtain an optimal queuing model at the drug collection counter at the Meko Village Health Center. Based on the analysis, at this time the service at the drug collection counter at the Meko Village health center that uses queues with a single channel single phase (M/M/1) model is not optimal. To optimize services, the application of the multi-channel single phase multiple line queue model (M/M/c) where c = 3 results in a measure of system performance, namely the probability of no customers in the system ( ) is 0.034 = 3.4%, the service utility rate (ρ) is 0.866 = 86.6%, number patient in the queue ( ) is 5 customers, number patient in the system ( ) is 8 customers, waiting time in the queue ( ) is 22,38 minutes, and waiting time in the system ( ) is 34,38 minutes. By applying the multi-channel single phase (M/M/c) multiple line queue model, it becomes an alternative solution in providing good and optimal service to patients at the Meko Village health center.

Abstract

Noise in electronic components of computed tomography (CT) detectors behaves like a virus that infects visual quality of CT scans and might distort clinical diagnosis. Modern CT detector technology incorporates high-quality electronic components in conjunction with signal and image processing to ensure optimal image quality while retaining benign doses of x-rays. In this study, a new strategy in signal and image processing directions is proposed by finding the most optimal wavelet base for denoising low-dose CT scan data. The process begins by selecting the appropriate wavelet bases for CT image denoising, followed by a wavelet decomposition, thresholding, and reconstruction. Other methods, such as graph wavelet and learning-based, are used to assess the consistency of the outcomes. The wavelet base of biorthogonal 5.5 achieves the highest optimum performance for CT image denoising. Meanwhile, the Daubechies wavelet base is inconsistent and performs poorly compared to the optimum base. This research highlights the importance of wavelet properties such as orthogonality, regularity, and the number of vanishing moments in selecting an appropriate wavelet basis for noise reduction in CT images.

Abstract

This study explores the use of Convolutional Neural Network to identify and classify regional batik motifs, a significant aspect of Indonesian cultural heritage. The CNN model was optimized with Adam optimizer and used to extract distinctive features from the batik patterns. Subsequently, a hierarchical clustering method was employed to construct a relationship tree depicting the link between batik motifs based on their region. The research findings demonstrate that the CNN model effectively classifies batik motifs with an accuracy of up to 88%. The study provides insights into the intricate connections between regional batik designs and contributes to the preservation and understanding of Indonesia's cultural heritage.

Abstract

The Prevalence of Stunting in Sigi Regency remains notably high at 36.8%, significantly above the national target. Stunting is frequently caused by recurrent infections, poor sanitation, and chronic nutritional deficiencies. Since stunting is a condition of chronic malnutrition that impairs a child's physical and cognitive development, an early warning system is essential for prevention. This study proposes the development of a web-based application to predict the risk of stunting in vulnerable families. Families are the primary focus as they serve as the first environment where children grow and develop. If risk factors are present within a family, the likelihood of stunting increases. Therefore, early detection is crucial for mapping family health conditions. By predicting stunting risks, families can take preventive measures before the condition severely impacts the child. This early warning system serves as a critical alarm, encouraging families to be more vigilant in maintaining the health of all household members. The stunting prediction system is developed as a web-based application, utilizing 11 variables for early stunting detection and employing the K-Nearest Neighbor (K-NN) method. The model's accuracy is evaluated using a Confusion Matrix, achieving an accuracy rate of 99.991%. Keywords: Early Warning System, Stunting, Classification, K-Nearest Neighbor, Confusion Matrix

Abstract

Pengabdian ini bertujuan meningkatkan kesiapan siswa SMP IT Bina Insan Palu dalam menghadapi Olimpiade Sains Nasional (OSN) bidang matematika melalui pelatihan dan pendampingan intensif. Metode yang digunakan meliputi sosialisasi, seleksi awal terhadap 22 siswa, pelatihan tiga kali seminggu selama tiga bulan, serta evaluasi berkala. Hasil pelaksanaan menunjukkan adanya peningkatan rata-rata skor peserta secara signifikan dari 36.6 pada pre-test menjadi 61.5 pada post-test, dengan kenaikan bervariasi antar individu antara 52.6% hingga 82.9%. Meskipun terjadi perbaikan konsisten, skor tertinggi post-test hanya mencapai 68. Kegiatan ini membuktikan bahwa metode pendampingan terstruktur efektif memperbaiki pemahaman konseptual dasar, namun penguatan materi berpikir tingkat tinggi masih memerlukan waktu pembinaan lebih panjang. Program pengabdian ini memberikan dampak positif dan terukur terhadap kompetensi dasar peserta, namun diperlukan strategi berkelanjutan dan integrasi materi HOTS dalam pembelajaran reguler untuk menjembatani kesenjangan menuju level kompetisi nasional.
