This research proposed new method to improve performance of WSN. It used network coding on transmission scheme. The researcher had modified the existing network coding multipath routing for a novel node selection to own residual power node in network coding routing mechanism and to improve reliability of a WSN. This routing mechanism was placed in router for routing purpose. Then, Software network simulation method was done by using OMNET++ platform and MiXiM Framework library. The result shows that proposed method to select nodes and execute network coding succeeds on improving performance of WSN like the reliability compared to the previous method.

To provide convenience for the user that frequently read the news, a system to gather, classify, and provide news from several news websites in one place was needed. This system utilized a recommender system to provide only relevant news to the user. This research proposed a system architecture that used vector space model, and Rocchio relevance feedback to provide specific news recommendation to user’s feedback. The results are that the proposed system architecture can achieve the goal by using five levels of feedback from the user. However, the time needed to gather news is increasing exponentially in line with the number of terms gathered from articles.

The research wanted to find the workflow and solution by developing m-learning object for Android and iOS-based smartphone and tablet that supported interactive multimedia. The research began with analysis, design, implementation, and evaluation. Currently, the learning objects were not compatible with mobile devices. To overcome this problem, the research focused on designing the instructional design for m-learning and the development of interactive multimedia. Instructional design was created by the collaboration of the subject matter expert and instructional designer. M-learning was designed using UML and developed using Adobe AIR technology. The implementation of this research was a prototype of m-learning for concept of cost in Faculty of Economics, Bina Nusantara University. Then, the evaluation was conducted by distributing m-learning object to 32 selected students by simple random sampling in their first week of lectures in February 2014. The observation was conducted during m-learning object installation and initial learning process. At the end of the second week of the experiment, summative assessment and questionnaire were given to students. The results show that m-learning object is compatible with mobile devices. The students also say that m-learning is easy to use and helpful for their learning.

The purpose of this research was to produce a learning management system that could provide teaching materials and assessment tools for students so that they could improve their abilities and assess themselves. Using the waterfall Software Development Life Cycle (SDLC) model, the researchers divided the development into five phases. Those were analysis, design, implementation, testing, and maintenance. Analysis phase was done by conducting interviews and observations. The designing phase used Unified Modelling Language (UML), and implementation phase used PHP language with Model View Controller (MVC) framework CodeIgniter. Then, testing used eight golden rules and questionnaire as user acceptance test. In the end, this research could produce a Learning Management System (LMS) namely Online Learning System. It can deliver materials to students in Bina Nusantara University. In addition, it helps students to find additional learning materials for the programming course, monitor, and assess their learning progress through the quiz and member dashboard.

The aim of this research was to find the effect of the combination of soybean and pumpkin seeds on the chemical characteristics of pumpkin seed tempeh. The pumpkin seed tempeh samples were analyzed for its water, ash, protein, fat, carbohydrate and crude fiber. Meanwhile, support data were isoflavone and zinc. Sensory hedonic was conducted by 25 untrained panelists for selecting the best formulation of soybean and pumpkin seeds in tempeh. The result shows the formulation of soybean and pumpkin seeds in various combinations (100:0, 85:15, 70:30, 55:45, and 40:60). It gives a significant effect on the water, protein, fat, carbohydrate, and crude fiber. Moreover, all acceptance on pumpkin seed tempeh is on the level of α = 0,01 and α = 0,05. The best combination of soybean and pumpkin seeds is 40:60, with chemical analysis results which are water (33,7%), ash (5,31%), protein (65,65%), fat (54,57%), carbohydrate (5,94%), crude fiber (14,06%) (db), zinc (30,05 ppm), and isoflavones (42,10 mg/100g). Chemical characteristics of the selective pumpkin seed tempeh have fulfilled SNI 3144-2015 regarding water, protein and fat.

The goal of the research was to design a mobile application of inventory system in a minimart. In an application of using the mobile-based inventory minimart, J2EE system development used Waterfall method with the stages of analysis, design, coding, and implementation. The control of application inventory items at the minimart was intended for mobile-based users who controlled the supply of goods on the markets. It was to facilitate employee minimart in organizing, processing, monitoring the movement of inventory items that occurred in the minimart. The application of control inventory-based mobile minimart was to make users inventory, with a menu that was available in the form of product items, a promotion that had a limited promotion item reservations. The application can make employees in a minimart organize, process, and monitor the movement of inventory item more easily.
