Covid-19 merupakan salah satu pandemi yang melanda dunia saat ini termasuk juga indonesia sampai tulisan ini dibuat. Untuk itu pemerintah membuat kebijakan guna meminimalisir penyebaran virus Covid-19, salah satunya adalah penggunaan masker. Masker digunakan untuk mencegah penularan virus Covid-19 melalui percikan saat batuk ataupun bersin antar manusia. Oleh karena itu penggunaan masker menjadi sangat penting untuk melakukan kegiatan sehari-hari saat keluar rumah.  Dalam hal ini diperlukan sebuah deteksi penggunaan masker pada wajah untuk mengetahui apakah orang tersebut menggunakan masker atau tidak. Penelitian ini mengusulkan penerapan metode  Bag of Visual Word dalam melakukan pengenalan citra masker pada wajah. Sampel yang digunakan sebanyak 1600 sampel dimana terdiri dari 1000 sampel data pelatihan dan 600 sampel data pengujian. Dari hasil pelatihan diperoleh tingkat akurasi sebesar 94.5% dan proses pengujian memperoleh tingkat akurasi sebesar 85%.

College accreditation by BAN-PT is one of the parameters in determining the quality of universities in Indonesia. As consideration to achieve the standard from BAN-PT, so they have an evaluation process itself in study program or college to be meet the standard universities when set by the BAN-PT. In carrying out the process of self evaluation, required data source that is used as the basis in assessing on a criteria. In most of the study program, all data spread on the system information and physical document that different, that is require more time and effort to integrate up to interpret. Data warehouse fight important in collecting data that spread and become an information. The process data warehouse with ETL used to integrate, extract, clean, transforming and reload into the data warehouse. With the existence of the data warehouse on Academic STIMIK STIKOM Bali can make it easier for executives to get the information to support the standard accreditation standart three and can be used as a reference in decision making.

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%.

Direct marketing provides an advantage in approaching consumers. Communication that happens allows us more closely, able to change the behavior and know the needs required by consumers accurately. But this technique has a lack of time. It takes a long time to convince consumers to buy the products offered. Bussines intelligent with data mining approach to consumer data is required. This process will analyze the potential possessed by a consumer. At the stage of the DSS used SVM method to predict whether consumers will buy products that have been offered. Bussines intelligent built proven able to predict consumers who have the potential to buy products. Tests show the greatest prediction accuracy rate is 89.5% with a combination of data traning of 70% of the dataset.
