Abstract

Barista is a person who works in a coffee shop as a delicious coffee maker. So it is necessary to recruit baristas who can work in coffee shops and have responsibilities that not only mix coffee but also have skills in processing coffee beans. The problem in the barista recruitment process is the process of determining barista candidates who are only selected individually so that it is less accurate to get barista candidates who have the expected skills so that it can have an impact on opinions on the coffee shop. So the solution is provided through a decision support system, a highly interactive computer-based system that assists in making a decision to utilise data and models in solving unstructured and semi-structured problems. The method used in making these decisions is the Additive Ratio Assessment Method (ARAS). A total of 11 people who will become data samples and five criteria are used as rules for assessing (selecting). The ARAS method is able to provide maximum results to obtain superior barista recruitment with a result of 5,342, namely A1 as the selected alternative in barista recruitment after going through the method application stage.

Abstract

Pola efek samping yang dialami pasien HIV yang menjalani terapi antiretroviral (ARV) menggunakan metode K-Means Clustering. Data yang digunakan berasal dari rekam medis pasien di puskesmas, yang mencakup informasi tentang usia pasien, jenis efek samping, durasi terapi ARV, dan pola penggunaan obat ARV. Metode Elbow dan Silhouette Score digunakan untuk menentukan jumlah cluster optimal, yang menghasilkan tiga cluster dengan tingkat pemisahan yang baik. Cluster pertama mencakup pasien dengan efek samping ringan dan durasi terapi pendek (kurang dari 6 bulan), cluster kedua berisi pasien dengan efek samping sedang dan durasi terapi menengah (6-12 bulan), sementara cluster ketiga meliputi pasien dengan efek samping berat dan durasi terapi lebih panjang (>12 bulan). Hasil clustering ini memberikan wawasan penting untuk perencanaan intervensi medis yang lebih tepat sasaran, seperti pemantauan rutin untuk cluster 1, pendekatan khusus untuk cluster 2, dan perhatian medis intensif untuk cluster 3. Visualisasi data dengan scatter plot mengilustrasikan hubungan antara keparahan efek samping dan durasi terapi, memudahkan pemahaman tentang pola distribusi pasien yang mengalami efek samping ARV. Temuan ini diharapkan dapat meningkatkan kualitas perawatan dan kepatuhan pasien terhadap terapi ARV.

Abstract

This research aims to analyze the factors that influence students' delays in completing final assignments using the Random Forest algorithm. The data used includes variables such as GPA, number of credits, employment status, frequency of guidance, organizational activities, and personal motivation. These variables were analyzed to determine their effect on students' ability to complete their final assignments on time. The Random Forest model is applied to predict whether students complete their final assignments on time or not. The model results show an accuracy of 63.33%, with the frequency of guidance and personal motivation being the most influential factors in completing the final assignment on time. Followed by the number of credits and GPA, which also have a significant but smaller influence. Organizational activity factors and employment status have a lower contribution to tardiness, but are still relevant in the context of student time management. Based on these results, research suggests the importance of academic guidance support and motivation management to help students overcome obstacles in completing their final assignments on time. This research, which uses the case of ITKES Ika Bina students, is expected to provide recommendations for universities in improving the academic mentoring process to support student graduation.

Abstract

Improving the quality of maternal healthcare requires an innovative, technology-based approach, particularly in providing midwifery education. This community service project aimed to introduce and train pregnant women at the Rantauprapat City Community Health Center (Puskesmas) in the use of an educational chatbot based on the Recurrent Neural Network (RNN) algorithm. This chatbot was designed to provide fast, relevant, and accessible pregnancy health information. The activity involved coordination with partner health centers, outreach, hands-on training on the use of the chatbot, and evaluation of its effectiveness. The evaluation results showed that more than 90% of participants felt the chatbot helped them understand their pregnancy status, with the majority of questions related to early symptoms, diet, and safe activities during pregnancy. Furthermore, health workers stated that the chatbot could ease the burden of answering repetitive questions from patients. The implementation of this technology has significantly contributed to improving digital-based midwifery literacy and strengthening the role of community health centers as primary health care centers that are adaptive to technological developments. Going forward, the development of additional features and the expansion of local content are expected to strengthen the use of the chatbot on a broader scale.
