Abstract

Kompetensi adalah suatu kemampuan atau kecakapan yang dimiliki oleh seseorang dalam melaksanakan suatu pekerjaan atau tugas di bidang tertentu, sesuai dengan jabatan yang disandangnya. Pendapat lain mengatakan arti kompentesi adalah suatu keterampilan, pengetahuan, sikap dasar, dan nilai yang terdapat dalam diri seseorang yang tercermin dari kemampuan berpikir dan bertindak secara konsisten. Dengan kata lain, kompetensi tidak hanya tentang pengetahuan atau kemampuan seseorang, namun kemauan melakukan apa yang diketahui sehingga menghasilkan manfaat. Dalam penelitian ini difokuskan pada klasifikasi siswa berkaitan dengan kompetensi yang dimiliki, pendekatan penelitian ini menggunakan algoritma decission tree, dengan tujuan mendapatkan pola rekomendasi kompeten dan tidak kompeten. Berdasarkan hasil penelitian menjelaskan bahwa akurasi yang didapat yaitu sebesar 76,96 %

Abstract

The impact of stunting on babies is an important parameter for assessing the health and welfare of children in an area. Stunting, often triggered by demographic and health factors, has serious implications for children's physical and cognitive growth. This research aims to understand the impact of demographic and health factors on stunting in children in Tukdana District, Indramayu Regency. Through data analysis, factors such as maternal age, access to clean water, sanitation facilities, and baby weight and length status were identified as significant contributors to stunting. The Decision Trees method was used to identify factors that play a role in stunting in babies, with an accuracy rate of 95.43%. The implications of this research include planning more effective interventions to deal with stunting, both in Tukdana District and in similar areas in Indonesia. Even though the majority of babies in Tukdana District have good nutritional status, further monitoring and prevention efforts are still needed to ensure optimal nutritional well-being for them. In conclusion, this research highlights the importance of identifying factors that cause stunting in infants in Tukdana District, as a basis for planning more effective interventions.

Abstract

Poverty is a condition where an individual or a group experiences economic incapacity to meet their basic needs, and this study involves broader aspects than just expenditures. The focus of this research is on Ciherang and Ciaro Villages, located in the Nagreg Subdistrict, Bandung Regency, which are areas with significant levels of poverty. This research responds to poverty issues by utilizing the K-Nearest Neighbor (KNN) Algorithm in the data mining classification process. KNN considers the proximity of a new object to its nearest neighbors, and as a supervised learning algorithm, KNN requires target information or classes in the analyzed dataset. The aim of this research is to provide information regarding the classification of recipients of Direct Cash Assistance (BLT) in Ciherang and Ciaro Villages. The research results present data on criteria for determining whether recipients are considered eligible or ineligible for BLT, with an accuracy rate reaching 81.56%. Additionally, the performance of this algorithm is demonstrated through true recall values for both eligible and ineligible recipients, with recall for true ineligible recipients at 88.43%, recall for true eligible recipients at 74.80%, precision for eligible recipients at 86.79%, and precision for ineligible recipients at 77.54%. These findings provide a basis for more accurate decision-making in determining BLT recipients in both villages. This can contribute to the design of more targeted and effective social policies in reducing the impact of poverty, providing in-depth insights into the characteristics of BLT recipients, and demonstrating the relevance and efficiency of the KNN algorithm in addressing complex social issues.

Abstract

Abstrak : Manajemen stok obat menjadi tantangan utama di apotek Nafa Farma untuk mencegah kelebihan atau kekurangan stok. Penelitian ini mengaplikasikan algoritma C4.5 sebagai metode klasifikasi untuk mendukung pengelolaan stok yang optimal. Data stok obat dari Januari sampai Desember 2023 dianalsis menggunakan pendekatan Knowledge Discovery in Database (KDD) dengan software RapidMiner. Penelitian ini menunjukkan bahwa algoritma C4.5 dapat meningkatkan efisiensi manajemen stok obat dengan akurasi 80,67% dan F1-score rata-rata 80.52% ini memberikan rekomendasi strategis untuk pengadaan obat. Obat kategori laku direkomendasikan untuk diutamakan dalam pengadaan, sementara obat tidak laku dapat dikurangi pembeliannya untuk menghindari pemborosan. Algoritma C4.5 efektif untuk meningkatkan efisiensi pengelolaan stok obat====================================================Abstract : Drug stock management is a major challenge at Nafa Farma pharmacy to prevent excess or shortage of stock. This research applies the c4.5 algorithm as a classification method to support optimal stock management. Drug stock data from January to December 2023 was analyzed using a Knowledge Discovery in Database (KDD) approach with RapidMiner software. This study shows that the C4.5 algorithm can improve the efficiency of drug stock management with an accuracy of 80.67% and an average F1-score of 80.52%, providing strategic recommendations for drug procurement.  Sellable category drugs are recommended to be prioritized in procurement, while unsellable drugs can be reduced in purchase to avoid waste. The C4.5 algorithm is effective in improving the efficiency of drug stock management.
