Abstract

In rental services, activity that usually do by rental provider are item ordering, item taking, item returning, item checking, and bookkeeping. Nowadays, many rental providers have difficulties for running their business activity, such as item scheduling, order recording, differences between item inventory and routine bookkeeping that causes losses and problems with customers. Moreover, the rental providers have limited infrastructure, by keep using rental note, whiteboard, and Microsoft Excel software for bookkeeping. Therefore, the rental providers need an rental management application which is independent in order to not depend on infrastructure or need more infrastructure, so that the service providers can only use smartphone without adding other infrastructure to manage rental services. This application designed using OOAD (Object Oriented Analysis and Design) method and REST web service. Designing this application include service design, architecture design, component design, data design, user interface design, and application design architecture. This design of application has been tested using Traceability Matrix, (Coupling Between Object Classes) CBO, (Response for a Class) RFC, (Lack of cohesion in methods1) LCOM1 metrics, and (Lack of cohesion in methods2) LCOM2 metrics. The result of this application design has low coupling because of the CBO's average value<=5 and RFC's average value<=100 so it have high understandability and low cohesion because of LCOM>1. The result of this application design also has high adaptability because of the CBO's average value is between 1 and 3, RFC's average value between 1 and 69, and fulfill LCOM2's value between 0 and 1. Furthermore, all artifacts are made based on the use case that was made before, because each column and row in the traceability matrix have a value of 1.

Abstract

Mobile Ad Hoc Network (MANET) is a type of ad hoc network that has a dynamic and fast-changing topology in which nodes on MANET are dynamically connected in an orderly manner. In this study Fisheye State Routing (FSR), a routing protocol uses a link state algorithm optimization using the fisheye approach. From the use of these techniques, each node will be grouped according to the distance or hop. In this case the use of energy becomes a matter that needs to be considered in the consumption of energy used in the simulation using NS-2.35. By using energy models, the simulations can produce presentations of energy consumption at nodes with different mobility. the total consumption scenario with the number of nodes 20,30 and 50 in each mobility shows that static mobility has the largest total energy consumption in 2 node scenarios namely 20 and 30 nodes namely 19997,969 and 29995,565 joules but static mobility has less in total energy consumption compared to the other 2 mobility with the use of 50 nodes, which is 499973,065 Joules. In the scenario the average energy consumption has the same results as the total energy consumption scenario. Increasing and decreasing energy consumption in mobility used by different nodes can be influenced by changes in the number of nodes and changes in mobility of each node.

Abstract

News is an information about someone's needs to find out what is happening. Efforts to get relevant news from a variety of languages ​​and documents are not easy to obtain. News documents usually written in foreign language. This becomes difficult because not all users understand foreign language, while the news needed in the collection of foreign language. Users can read one by one to get news as it needed, but this process is inefficient and will take a long time. A cross-language automatic news search system is needed to solve this problem, where users only enter requests with the native language and the system will recover documents in other languages. This problem can solve by creating a system to obtain automatic news without language barriers. This system will builds using the BM25 method which has been proven to be able to improve documents that are relevant to the ranking. The free parameters used are k1 = 2.5 and b = 8.0. Weighting is done by comparing IDF BM25 and IDF modification which results in the highest value of 0.95 with k = 5 in testing of precision@k.
