Abstract

Sparsity adalah satu masalah yang sering terjadi pada teknik collaborative clustering dimana user sedikit sekali memiliki informasi (pada penelitian ini rating) yang menyebabkan sistem seringkali tidak akurat ketika memberikan rekomendasi. Banyak metode yang bisa digunakan untuk menyelesaikan masalah sparsity data, salah satunya adalah metode KNN. Namun metode KNN memiliki kelemahan yaitu scalability. Scalability terjadi ketika ketika data yang harus dicari kesamaannya semakin besar. Salah satu solusi yang mungkin diimplementasikan adalah dengan mencari profil dari user dan mengelompokkannya menjadi satu kelompok. Eksperimen yang dilakukan pada penelitian ini untuk mengatasi masalah sparsity dan scalability adalah dengan menggabungkan algoritma silhouette, k-means, K-Nearest Neighbour. Dataset yang dipakai di penelitian ini, berjumlah 700 rating yang di crawling melalui web traveloka. Data rating antara user dan item akan disimpan dalam database, untuk selanjutnya dirubah menjadi bentuk array user-item. Hasil pengujian dengan 5 data uji didapatkan nilai rata-rata RMSE 1,33% dengan rata-rata akurasi = 100% - 1,33% = 98,67%.

Abstract

Wisanggeni Coffee adalah sebuah cafe yang terletak di kaki bukit Gunung Merapi. Ketatnya persaingan bisnis menuntut pemilik Wisanggeni Coffee untuk terus berinovasi dalam setiap penentuan strategi bisnisnya. Beberapa permasalahan yang ditemukan di adalah persaingan bisnis yang ketat membuat trend penjualan stagnan. Selain itu pemilik kesulitan untuk mendapatkan pola pembelian konsumen. Pola pembelian yang tidak terprediksi membuat pemilik kesulitan dalam penentuan stok bahan makanan, minuman dan souvenir yang dijual. Kurang terprediksinya pola konsumen juga sering membuat kehilangan kesempatan untuk menjual makanan, minuman dan souvenir karena out of stock. Memanfaatkan ilmu yang ada di bidang komputer yaitu asosiasi untuk mendapatkan pola pembelian konsumen di “Wisanggeni Coffee”. Aplikasi yang dibangun akan menggunakan metode apriori. Metode apriori akan menganalisa pola pembelian konsumen 1 bulan terakhir guna mendapatkan pola asosiasi antar produk makanan, minuman dan souvenir yang dijual. Hasil dari pengabdian ini adalah keinginan pemilik dalam membangun sistem asosiasi cukup baik. Pemilik langsung menerapkan aplikasi baik dalam pola menawarkan menu maupun mengatur tata letak souvenir di rak penjualan. Sebelumnya kami menargetkan sampai pada evaluasi hasil penerapan aplikasi apakah bisa meningkatkan penjualan. Namun karena pandemi Covid-19 tidak kunjung selesai, evaluasi ini kami tunda hingga kegiatan wisata pulih kembali.

Abstract

In this article, it can be seen through a literature review that peer-to-peer relationships are often associated with adolescent life. Students as academics are mostly still in that range, especially at the undergraduate level. They are the ones who are vulnerable to national turmoil that triggers violent behavior. They require intense interaction with the same age group in responding to existing changes and developments.
