Abstract   Inaccurate stock management will lead to high and uneconomical storage costs, as there may be a void or surplus of certain products. This will certainly be very dangerous for all business people. The K-Means method is one of the techniques that can be used to assist in designing an effective inventory strategy by utilizing the sales transaction data that is already available in the company. The K-Means algorithm will group the products sold into several large transactional data clusters, so it is expected to help entrepreneurs in designing stock inventory strategies.   Keywords: inventory, k-means, product transaction data, rapidminer, data mining   Abstrak   Manajemen stok yang tidak akurat akan menyebabkan biaya penyimpanan yang tinggi dan tidak ekonomis, karena kemungkinan terjadinya kekosongan atau kelebihan produk tertentu. Hal ini sangat berbahaya bagi para pelaku bisnis. Metode K-Means adalah salah satu teknik yang dapat digunakan untuk membantu dalam merancang strategi persediaan yang efektif dengan memanfaatkan data transaksi penjualan yang telah tersedia di perusahaan. Algoritma K-Means akan mengelompokkan produk yang dijual ke beberapa cluster data transaksi yang umumnya besar, sehingga diharapkan dapat membantu pengusaha dalam merancang strategi persediaan stok.   Kata kunci: data transaksi produk, k-means, persediaan, rapidminer, data mining.

In this study, we outline a maritime perspective on interaction in the Late Bronze/early Iron Age Mediterranean. In response to what has elsewhere been termed the ‘maximalist’ approach, which foregrounds direct, long-distance trading connections between distant Mediterranean regions as a key feature of Late Bronze Age exchange systems, we propose a more nuanced, ‘minimalist’ and argue that notions of contact, connectivity and mobility need to be carefully distinguished if we wish to discuss both the material and social dimensions of maritime mobility. In particular, we critique the prominently proposed, allegedly direct trade route between Sardinia and Cyprus. The network we suggest hinges on multiply connected nodes, where a variety of social actors take part in the creation and maintenance of maritime connections. By unpacking several such nodes between Sardinia and Cyprus, we demonstrate that simply asserting the dominance of Sardinian, Cypriot or Aegean mariners falls short of the complex archaeological evidence and eschews possible social interpretations. In conclusion, we submit that maritime connectivity is an inherently social activity, and that a culturally diverse prehistoric Mediterranean was connected by multiple interlocking and overlapping networks.
