Mapping the Indonesian territory, based on pollution, social demography and geographical data, using self organizing feature map

This research aims to mapping the 33 (thirty-three) provinces in Indonesia, based on the data on air, water and soil pollution, as well as social demography and geography data, into a clustered model. The method used in this study was unsupervised method that combines the basic concept of Kohonen or Self-Organizing Feature Maps (SOFM). The method is done by providing the design parameters for the model based on data related directly/ indirectly to pollution, which are the demographic and social data, pollution levels of air, water and soil, as well as the geographical situation of each province. The parameters used consists of 19 features/characteristics, including the human development index, the number of vehicles, the availability of the plant’s water absorption and flood prevention, as well as geographic and demographic situation. The data used were secondary data from the Central Statistics Agency (BPS), Indonesia. The data are mapped into SOFM from a high-dimensional vector space into two-dimensiona...

Pelatihan Pembuatan Buku Elektronik Interaktif

Membaca bukanlah proses yang tunggal melainkan sintesis dari berbagai proses yang kemudian berakumulasi pada suatu perbuatan tunggal. Mmembaca pada hakikatnya adalah suatu proses yang bersifat fisik dan psikologis. Proses yang berupa fisik berupa kegiatan mengamati tulisan secara visual dan merupakan proses mekanis dalam membaca. Proses mekanis tersebut berlanjut dengan proses psikologis yang berupa kegiatan berpikir dalam mengolah informasi. Proses pskologis itu dimulai ketika indera visual mengirimkan hasil pengamatan terhadap tulisan ke pusat kesadaran melalui sistem syaraf. Pelatihan pembuatan buku elektronik interaktif berjalan dengan baik. Peserta pelatihan antusias dalam mengikuti pelatihan dan mereka berkehendak untuk mencoba memanfaatkan program HHW (HTML Help Workshop) tersebut untuk membuat buku elektronik menjadi lebih baik dan menarik. Motivasi peserta juga meningkat setelah mereka mengikuti pelatihan ini. Mereka mendapatkan ide-ide baru seperti fitur apa saja yang dapat menambah desain buku eletronik menjadi lebih menarik dan interaktif. Tampak pula sebagian besar peserta merasa mendapatkan manfaat pelatihan untuk mengembangkan ide-ide dalam membuat buku eletronik secara interaktif dan menarik Kata kunci: buku eletronik, interaktif, HHW (HTML Help Workshop)

Selecting suitable solution strategies for Classes of graph coloring instances using data mining

The Maximal Independent Set (MIS) formulation tackles the graph coloring problem (GCP) as the partitioning of vertices of a graph into a minimum number of maximal independent sets as each MIS can be assigned a unique color. Mehrotra and Trick [5] solved the MIS formulation with an exact IP approach, but they were restricted to solving smaller or easier instances. For harder instances, it might be impossible to get the optimal solution within a reasonable computation time. We develop a heuristic algorithm, hoping that we can solve these problems in more reasonable time. However, though heuristics can find a near-optimal solution extremely fast compared to the exact approaches, there is still significant variations in performance that can only be explained by the fact that certain structures or properties in graphs may be better suited to some heuristics more than others. Selecting the best algorithm on average across all instances does not help us pick the best one for a particular instance. The need to understand how the best heuristic for a particular class of instance depends on these graph properties is an important issue. In this research, we use data mining to select the best solution strategies for classes of graph coloring instances.
