The explosion of digital data in the last two decades followed by the development of various types of data, including text, images, audio and video known as multimedia data. Multimedia Information Retrieval is required to search various type of media. There is comprehensive information need that can not be handled by the monolithic search engine like Google, Google Image, Youtube, or FindSounds. The shortcoming of search engine today related to their format or media is the dominance of text format, while the expected information could be an image, audio or video. Hence it is necessary to present multimedia format at the same time. This paper tries to design Unified Concept-based Multimedia Information Retrieval (UCpBMIR) technique to tackle those difficulties by using unified multimedia indexing. The indexing technique transforms the various of media with their features into text representation with the concept-based algorithm and put it into the concept detector. Learning model configures the concept detector to classify the multimedia object. The result of the concept detector process is placed in unified multimedia index database and waiting for the concept-based query to be matched into the Semantic Similarities with ontology. The ontology will provide the relationship between object representation of multimedia data. Due to indexing text, image, audio, and video respectively that naturally, they are heterogeneous, but conceptually they may have the relationship among them. From the preliminary result that multimedia document retrieved can be obtained through single query any format in order to retrieve all kind of multimedia format. Unified multimedia indexing technique with ontology will unify each format of multimedia

A cost expenditure of software defined radio software has limiting the development of cognitive radio in third countries. Moreover, a complexity of signal processing library in a SDR platform has contributed to the hard implementation in real applications. In this works, the development of SDR platform with low cost expenditure is proposed. Arduino UNO and X Bee uses for the OFDM based spectrum exchange information. In a case of spectrum sensing scenario, the objective of the local spectrum sensing is to detect the PU’s signal detection. The performance of SN ability to sense the PU’s signal is crucial. It was shown that from the previous works as the detected power is quantized into information bit is simulated. In order to implemented the spectrum exchange information during sensing, Arduino UNO and X Bee is implemented to sense the presence of PU activity channels of wifi terminals based on the energy of the signals. The detected power (RSSI) of wifi terminals is exchanged into an OFDM subcarrier tone signal such as orthogonal sub-channel that being equally divided from the licensed band. The results shows that using proposed software defined radio (SDR) based on Arduino and X Bee, the cognitive radio spectrum sensing is applied. The received power from the PU’s channels such as wifi networks can be detected as well. The system could received and exchanged into OFDM-based subcarrier information bits.

Nowadays, security is a part that consent by many institution including academic for example in University campus, some of campus have been implement automatic system in campus area to control visitor to enter University also for the staffs and students, but the system is in standalone with introduce new gate pass. Most of University has been use Information Technology (IT) in application for academic system such as student information, registration, results information, etc. In this paper discuss on integration of student information to gate pass system then do not require new card or pass for every student to enter campus area. Gate pass system is required information to match to database that who allow entering to campus, normally a new database is create for the system. In this case, University has student and staff database including lecturer, thus to be efficient the data in existing database can be use and integration using protocol that gate pass system give a command to database as request then verification of those data. Currently, student database stored in server room and the place far away from gate pass system, in order to make it transaction faster for visitor to enter then a mini database is setup onsite of gate system, but periodic updating is require or every new update in database. Results shows, database stored in student information system is more than 30,000 number of student and transaction time is less than 1 second and in average cycle time is 5.5 seconds for motorcycle lane and 7 seconds for car, that mean time for visitor to access gate pass system for entry campus is most reasonable.

AbstrakKredit merupakan salah satu perilaku ekonomi modern. Dalam prakteknya kredit dapat berupa peminjaman sejumlah uang atau pembelian barang dengan proses pembayaran secara bertahap dan dalam jangka waktu yang telah disepakati. Kondisi perekonomian yang kurang mendukung serta kebutuhan masyarakat yang tinggi membuat masyarakat memilih membeli barang dengan proses kredit ini. Sayangnya kebutuhan yang tinggi ada yang tidak diimbangi dengan kemampuan melakukan pembayaran sesuai dengan perjanjian awal. Kondisi ini yang memungkinkan proses pembayaran menjadi tidak lancar atau disebut juga dengan istilah kredit macet. Penelitian ini menggunakan data publik yaitu dataset kartu kredit dari UCI repository serta data private yaitu dataset persetujuan kredit dari perbankan lokal. Algoritma information gain digunakan untuk menghitung bobot dari masing masing atribut yang ada. Dari hasil perhitungan diketahui bahwa semua atribut memiliki bobot yang berbeda. Penelitian ini menghasilkan kesimpulan bahwa tidak semua atribut data mempengaruhi hasil klasifikasi. Misalkan atribut A1 pada dataset UCI serta atribut type pinjaman pada dataset lokal yang memiliki bobot information gain 0 (nol). Hasil klasifikasi menggunakan algoritma K-Nearest Neighbour menunjukkan bahwa terjadi peningkatan sebesar 7,53% untuk dataset UCI dan 3,26% untuk dataset lokal setelah dilakukan seleksi fitur pada kedua dataset.Â Kata kunci: Akurasi KNN, seleksi fitur, Persetujuan Kredit.
