Mask, often known by Balinese as “Tapel”, is made of pule wood. It depicts the representation of characters in the “badbad” or legend. Bali has many types of mask dances that are often performed, which makes tourists interested in visiting Bali. Unfortunately, many tourists do not know the information contained in Balinese masks. The most important information contained in the character of the Balinese masks. The characters of each mask are different even though they have the same type. As mask art is also a cultural heritage from generation to generation, it needs to be preserved. It is necessary to have information in the form of technology that can distinguish the characters from Balinese masks. In this study, bag of visual word method in the classification process of Balinese mask characters is used, where in this method, there are several algorithms used, namely SURF as feature detection, K-Means as a clustering process to get the value of feature quantization, and SVM as a classification of Balinese mask character. The result of the accuracy level obtained from the testing process is 80%.

Alongside with development of technology, more business need support of business intelligence tools to transform its data in a meaningful way which is accumulated rapidly in every transaction occurred. In order to achieved that, data warehouse with its online analytical processing (olap) can be considered as a solution. One tools for creating an olap from data warehouse is SSAS. This tools consist of two models, first one is multidimensional models or can be said the traditional one and the new one is tabular models. One best feature that tabular models give is the time needed for building it. The tabular models does not require the data in format of fact and dimension tables so reduce the time to change particular data into some scheme (star or snowflake). Hence, the purpose of this research is to design a data warehouse for minimarket’s sales information using the advantage of tabular modeling for creating the analysis. Its also known that, the data analysis created using tabular, support reporting application such as pivot table excel, so the user not need to create a new application for reporting analysis

Illegal transshipment merupakan aktivitas pemindahan atau pertukaran kargo, persediaan kapal, personel, atau hasil tangkapan ikan antara dua kapal di laut jika tidak dilaporkan kepada otoritas pelayaran di pelabuhan. Dalam konteks IUU (Illegal, Unreported, Unregulated) Fishing, aktivitas illegal transshipment perlu diawasi untuk mengamankan devisa negara dari sektor perikanan laut dan mengamankan daerah tangkapan ikan untuk keberlangsungan mata pencarian nelayan tradisional. Dengan memanfaatkan cakupan dari teknologi pada Automatic Identification System (AIS) memungkinkan untuk melakukan pengawasan terhadap kegiatan illegal transshipment yang terjadi di laut. Pada penelitian ini, kami mengembangkan sebuah kerangka kerja yang mengekstrak pengetahuan dari data AIS untuk medapatkan aktivitas kapal yang terindikasi melakukan kegiatan illegal transshipment. Memanfaatkan teknik klasterisasi berbasis kepadatan mampu mengelompokkan titik lintasan kapal yang memiliki pola menyerupai aktivitas illegal transshipment. Berdasarkan pengujian dengan metode Silhouette Coefficient, kualitas klaster yang dihasilkan pada kerangka kerja yang dibangun memiliki hasil yang cukup kuat. Selain itu, pengujian skor Silhouette pada klasterisasi tanpa tahapan pada kerangka kerja juga dilakukan untuk membandingkan kualitas klaster. Dari hasil perbandingan tersebut, diketahui bahwa proses pada kerangka kerja yang dibangun mampu meningkatkan kualitas klaster dari DBSCAN.

The hospital information system has been regulated in Law Number 44 of 2009 concerning Hospitals. The law states that every hospital is required to record and report all hospital operations in the form of a hospital management system. In this regard, the research conducted at Wangaya Regional General Hospital, Denpasar City, aims to determine the performance calculation of the fiber optic network design at the hospital so that SIMRS implementation can be carried out optimally. This research uses Optisystem 7.0 simulation to determine the performance of network design at Wangaya Regional General Hospital, Denpasar City. Optisystem simulation with MMF OM4 cable produce a power receive value greater than allowable minimum receiver sensitivity, that is -11.1 dBm. The BER value obtained from the Optisystem simulation is less than 1x10-9 which indicates that the value has met the adequacy of the standard BER value in fiber optic networks. However, the Q-factor value obtained in the simulation is greater than the optical communication standard, that is 6. This design is feasible to implement using MMF OM4 cable from the results of testing with Optisystem simulations.

Higher Education, or tertiary education, is the final stage which is optional in formal education. It is usually organized in the form of a university, academy, seminary, high school, or institute. Every tertiary institution needs qualified and professional educators because they have an important role in the process of implementing the Tri Dharma of Higher Education. Recruitment for teaching staff usually has several stages and standardization of assessment in selection proces. In order for the process of selecting educators to be carried out objectively, a support system is need to carry out the assessment process. This study applies the Fuzzy K-Nearest Neighbor (FK-NN) method for the classification process in determining prospective educators who pass or not. Data classification is a new data or object grouping into classes or labels based on certain attributes. The application of the FK-NN method has several stages, namely weighting the criteria, then calculating the closeness of the test data and training data, finding the value of k-nearest neighbors between the training data and testing data and determining the membership of each data. Tests were carried out using the Confusion matrix method on several variations of the k value where the highest percentage was obtained from the value of k = 5. The test results for all k values obtained an average accuracy rate of 89.22%, 89.22% precision and 82.45% recall with 114 training data and 50 test data. Based on the average value of the test results, it can be concluded that the FK-NN method is feasible and good to use for the selection of educators with the classification of pass or not.
