<![CDATA[Abstract: The selection of pediatric cough medicine at Apotek Keluarga is currently subjective and highly dependent on the pharmacist's experience, which potentially leads to inconsistent recommendations for customers. This research aims to develop a Decision Support System (DSS) using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to provide objective, fast, and accurate drug recommendations. The assessment criteria used in this system include cough type, side effects, age, and drug price, which are adjusted to clinical needs and consumer preferences. TOPSIS was chosen for its ability to rank drug alternatives based on their relative closeness to the positive ideal solution and the farthest distance from the negative ideal solution. The system development process involved problem identification, literature study, and data collection through interviews and direct field observations. The results indicate that the implementation of the TOPSIS method is effective in producing a list of cough medicine recommendations tailored to the specific conditions of pediatric patients. With this web-based system, the drug selection process becomes more transparent, systematic, and efficient, thereby enhancing the quality of pharmaceutical services at Apotek Keluarga.

Abstrak: Pemilihan obat batuk anak di Apotek Keluarga saat ini masih bersifat subjektif dan sangat bergantung pada pengalaman apoteker, sehingga berpotensi menimbulkan ketidakkonsistenan dalam pemberian rekomendasi kepada pelanggan. Penelitian ini bertujuan untuk mengembangkan Sistem Pendukung Keputusan (SPK) menggunakan metode Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) guna memberikan rekomendasi obat secara objektif, cepat, dan akurat. Kriteria penilaian yang digunakan dalam sistem ini meliputi jenis batuk, efek samping, usia, dan harga obat, yang disesuaikan dengan kebutuhan klinis serta preferensi konsumen. Metode TOPSIS dipilih karena kemampuannya dalam meranking alternatif obat berdasarkan kedekatan relatif terhadap solusi ideal positif dan jarak terjauh dari solusi ideal negatif. Proses pengembangan sistem dilakukan melalui tahapan identifikasi masalah, studi literatur, serta pengumpulan data melalui wawancara dan observasi langsung di lapangan. Hasil penelitian menunjukkan bahwa penerapan metode TOPSIS efektif dalam menghasilkan urutan rekomendasi obat batuk yang paling sesuai dengan kondisi spesifik pasien anak. Dengan adanya sistem berbasis web ini, proses pemilihan obat menjadi lebih transparan, sistematis, dan efisien, sehingga mampu meningkatkan kualitas pelayanan farmasi di Apotek Keluarga.
