Abstract

The purpose of this study is to perform database’s planning that supports Prototype Modeling Data Warehouse in the Ministry of Agriculture, especially in the Distribution Center and Reserves in the field of distribution, reserve and price. With the prototype of Data Warehouse, the process of data analysis anddecision-making process by the top management will be easier and more accurate. Research’s method used was data collection and design method. Data warehouse’s design method was done by using Kimball’s nine stepsmethodology. Database design was done by using the ERD (Entity Relationship Diagram) and activity diagram. The data used for the analysis was obtained from an interview with the head of Distribution, Reserve and Food Price. The results obtained through the analysis incorporated into the Data Warehouse Prototype have been designed to support decision-making. To conclude, Prototype Data Warehouse facilitates the analysis of data, the searching of history data and decision-making by the top management.

Abstract

Di dalam lingkungan bengkel resmi, diperlukan sistem rekomendasi yang kompatibel dengan jenis kendaraan yang digunakan oleh pengguna dan kondisi aktual dari kendaraan tersebut. Studi ini mengusulkan framework hybrid filtering berbasis konteks yang mengintegrasikan co-occurrence collaborative filtering, pemetaan kategori fungsional, dan skor siklus perawatan berbasis jarak tempuh dalam kombinasi weighted linear. Filter tipe sepeda motor juga digunakan untuk membatasi kandidat pada suku cadang yang kompatibel, selain itu tingkat urgensi perawatan digunakan untuk memastikan komponen yang perlu diganti berdasarkan pembacaan odometer kendaraan. Bobot dikalibrasikan melalui analisis sensitivitas grid search pada validation set yang terdiri dari 80 anchor parts, menghasilkan konfigurasi optimal dengan validation Precision@5 sebesar 17,1%. Evaluasi ahli oleh mekanik mengonfirmasi validitas rekomendasi sebesar 90,21%. Hasil ini menunjukkan bahwa penambahan beberapa komponen ke dalam hybrid filtering menghasilkan rekomendasi yang layak secara teknis.
