All-optical busbar differential protection scheme for electric power systems

This paper proposes a novel implementation of a differential protection scheme using magneto-optic current sensors. The proposed all-Optical Differential Protection (ODP) scheme utilizes inherent properties of magneto-optic sensors connected in series to perform differential protection functionality. In order to demonstrate the validity of the proposed scheme, all constituent components such as optical fibre, polarisers and Faraday rotators have been modelled using the Jones matrix representation. Through selected simulation-based case studies, including external and internal (high resistive and solid) faults, the paper demonstrates that the proposed novel ODP scheme for busbar protection meets the protection relaying performance criteria in terms of discrimination, sensitivity, stability, as well as ultra-high speed of operation

Perancangan Aplikasi Data Mining Dengan Algoritma Apriori Untuk Frekuensi Analisis Keranjang Belanja Pada Data Transaksi Penjualan (Studi Kasus Di Swalayan Kpri Universitas Brawijaya)

Penelitian ini berupaya mengembangkan strategi bisnis peletakkan barang belanjaan yang disesuaikan dengan pola konsumsi konsumen di Swalayan KPRI Universitas Brawijaya Malang. Metode yang digunakan adalah Market Basket Analysis (MBA) dengan memanfaatkan data transaksi penjualan selama bulan Februari 2013. Hasil peneltian ini adalah sebuah prototipe aplikasi MBA. Pengujian prototipe dilakukan dengan batasan minimum transaksi (support) sebesar 7 transaksi dan minimum confidence sebesar 5%. Dengan batasan tersebut, aplikasi MBA membentuk 11 aturan asosiasi. Salah satu aturan asosiasi yang terbentuk adalah jika membeli gula pasir lokal 1kg, indofood bmb.racik sayur sop 20gr 9117, maka membeli indofood bmb.racik sy.asem 20gr rsah.463 dengan nilai support = 0,52% dan nilai confidence = 90,91% yang merupakan aturan dengan nilai confidence tertinggi. Proses selanjutnya adalah mengkategorikan item yang digunakan sebagai acuan perbaikan layout, sehingga mendapatkan rekomendasi perbaikan layout yang menyatakan bahwa gula didekatkan dengan telur, bumbu masak jadi, dan minyak goreng; minyak goreng didekatkan dengan bumbu masak jadi; telur didekatkan dengan beras dan mie instant serta minuman didekatkan dengan roti. Dengan demikian, penataan barang dagangan bisa disesuaikan dengan aturan asosiasi agar sesuai dengan pola konsumsi konsumen
