Abstract

The selection of good achievement lecturers is a recognition for those lecturers who already had been conducting three principles of higher education with very good results. The selection of those lecturers in The University of Lampung is conducted annually. In the process of selection, the university will appoint assessing team to conduct assessments to the candidates. However, this assessment process is still conducted manually so that it will take a time to process the data. In addition, the assessment is still subjective in nature and is not yet relevant to the real conditions. Based on this background, the objective of this research was to build a decision support system to use in conducting selection process of good achievement lecturers in The University of Lampung. This decision support system was built based on web by using PHP programming language and MySQL as database, and Simple Additive Weighting method for making the decision. This method was used to determine point values of each criterion, and then ranked score was made to determine the best solution. The testing of the application using black box showed that this system was able to run properly. The results also influence the academic atmosphere and institutional quality. Keywords: decision support system, selection of good achievement lecturers , simple additive weighting

Abstract

Biology is part of science that have special characteristics different from other sciences, in terms of objects, issues and methods as well as having many terms and have the object form of the Kingdom (kingdom): Animalia (animal’s world), Plantae (plant’s world), Monera, Protista, and Fungi. Object numbering thousands of types into its own difficulties to learn it. One way to make it easier to learn it is grouping or classification of organism is called Taxonomy and the scientific name is called Binomial Nomenclature. In this study, to learn the classification and scientific nomenclature, then created taxonomy’s application based on Android, which aims to facilitate students in classifying organism consist of Kingdom, Sub Kingdom, Super Division, Division, class, Sub class, Ordo, Family, Genus, and species. This application is designed and then implemented using the Java programming language for Android, MySQL and Web Server to manipulate the data that is needed, and updates the database periodically. The results of data test using Equivalence Partitioning test shown the application functionate well according to the analysis. In addition, based on questionnaire data, that the application is a user friendly application (with an average value of 4,17 / good), and interactive (with an average value of 4,08 / good).Keywords : Android, Application, Binomial Nomenclature, Taxonomy.

Abstract

Augmented Reality (AR) is a term for an environment that combines real world and virtual world, where objects in real world can be recognized through the position, direction, and location. One of AR technology which is currently being developed is Markerless Augmented Reality, with this technology, users no longer need to use a marker to display digital elements. This technology can also be used to visualize information interactively, especially when this technology is integrated with mobile devices such as smartphones that have Android operating system. Camera feature, internet, accelerometer, digital maps and GPS (Global Positioning System) on Android devices can be integrated so that AR technology can be implemented. In this research, Markerless Augmented Reality technology is implemented to detect and find out the location of the nearest gas station in Bandar Lampung city. This application was designed and then implemented by using Java for Android programming language and Beyond AR framework to detect and display AR object and the Google Maps API to display a map of  location of gas stations. The result of testing data using an Equivalence Partitioning testing indicates that the application can function in accordance with the analysis. Additionally, based on questionnaire data, this application is a user friendly application (with an average grade of 4.29 / Excellent) and interactive (with an average grade of 4.20 / Well).

Abstract

Knapsack Problem (KP) is known as one of combinatorial optimization problem that maximizes the amount of value (profit/ priority) of some of the items chosen to put in a sack or a bag without exceeding its capacity. KP has been applied in many fields: cargo loading, budget control, financial management and etc. In addition, KP is also included in NP-Hard problem. Several research have been conducted using some heuristic method to solve it. Some of these methods are Branch and Bound, Greedy Algorithms, Dynamic Programming, and Genetic Algorithms.However, when using GA, the feasibility of chromosome is one of critical issue. Most of optimization problem has constraint functions that will change the feasibility of solution. GA has some strategies to handle this case on the evaluation step. Evaluation not only calculates chromosome’s fitness value, but also handles the infeasible chromosomes presence. There’re rejecting strategies, repairing strategies, and penalty strategy.This paper develops a strategy GA approach with chromosome repairing strategy. In order to see the performance of the algorithm, we have done numerical experiment with several test problems taken on certain literature. In addition, this study will also give variations in GA parameter to determine the efficiency and effectiveness of the algorithm.
