<![CDATA[The aims of this study are to apply design patterns for developing library information system and analyze them from re-usability aspect. The applied design pattern consists of Factory Patterns and Façade Patterns. Factory Patterns are used to separate the process of making objects from other purchased objects. The Façade Patterns are used to reduce connectivity among classes and the complexity of the system being built. To evaluate the patterns, object-oriented metrics were used, both system that do not apply the design pattern and the proposed system (system that apply the design pattern). The results of the Object Oriented Metrics analysis using the Coupling Between Object parameter showed the decrease of the connectivity among classes so that the system is easy to reuse, in which the parameter Response for a Class (RFC) showed the reduction of the method in the class on a system that applied the design pattern which made it easier to be understood and tested. In addition, using the parameter Line of Code (LoC) showed the reduction of 228 lines code of program, from 4410 to 4182 so that the system made the program size smaller and the library information system become easier to be maintained, reused, and understood.]]>

Data and information obtained from reviewing literatures about related research and testing the system. Hardware used includes Arduino Uno Board, Camera, TFT LCD Screen (Thin Film Transistor Liquid Crystal Display), Ultrasonic sensor, and a buzzer. Camera and Ultrasonic Sensor placed behind of vehicle which can help user in parking. Picture data obtained from Camera then displayed on TFT LCD which are placed on dashboard. To improve system accuracy, ultrasonic sensor are placed on rear bumper of the vehicle for reading distance which results are displayed to TFT LCD Screen and signals in sound. In result, sensor call still read well distance of the object if the position parallel to the object, when sensor position above object, sensor can read at a certain distance. Position of objects that get closer to the sensor make the level of sensor readings accuracy higher. Moreover in Camera OV7670 testing, Camera still can capture image well in the room that much light, whereas in the room less light images produced blurry.]]>

<![CDATA[Dalam mengembangkan sistem jaringan sensor, pengembang umumnya menggunakan bahasa pemodelan Unified Modeling Language (UML) untuk proses analisis dan rancangan sistem. Meskipun UML merupakan bahasa pemodelan yang efektif namun dipandang masih memiliki keterbatasan apabila digunakan dalam mendefinisikan beberapa spesifikasi dan aktifitas rancangan sistem. Olehnya itu dikembangkanlah System Modeling Language (SysML) untuk melengkapi keterbatasan yang ada pada UML tersebut. Penelitian ini bertujuan untuk menerapkan System Modeling Language pada pemodelan jaringan sensor nirkabel, secara khusus sistem monitoring lingkungan. Pengumpulan data dilakukan melalui studi literatur dan evaluasi sistem di atas platform arduino. Studi literatur merujuk pada penelitian sebelumnya yang menggunakan Unified Modeling Language (UML) dan pendekatan pengembangan Lightweight Process dalam memodelkan sistem jaringan sensor. Dalam penelitian ini, dua diagram SysML yaitu requirement dan parametric diagram digunakan sebagai karakteristik pemodelan sistem jaringan sensor berbasis SysML. Requirement diagram digunakan untuk mendefinisikan spesifikasi (requirement) sistem dan memetakannya kedalam diagram usecase, sementara parametric diagram digunakan untuk mendefinisikan kendala pada nilai parameter sistem seperti kinerja, keandalan, dan properti massa untuk mendukung analisis teknik dan dipakai untuk mendapatkan sebagian kode implementasi untuk platform mikrokontroller Arduino. Selain itu, evaluasi kode program yang dihasilkan di atas platform Arduino dengan dua node yaitu node sensor dan sink memperlihatkan sistem monitoring yang dikembangkan menggunakan bahasa SysML dapat melakukan pengindraan data temperatur dan kelembaban udara, mengirim data tersebut ke sink dan menampilkan hasilnya di komputer penerima.]]>
