Abstract

Technology development currently making human life be more practical. There are many ways to use technology like for entertainment, business, and education. The use of technology in education is still not optimal so that the educational process is still using the old system where students listen and the teachers explain. One of the education technology is to do the process of learning using the  multimedia interactive. Subjects about the solar system is one of the subjects taught in junior high school, but the topics about exoplanets or planets which are outside the solar system are seldom given by the teacher. Most junior high school used the interactive multimedia to help learning process but it is still 2D-based and only gave topics about the solar system. Therefore, in this paper we discused about the design and development of an interactive multimedia which contains topics about solar system and exoplanets with animated interactive multimedia in 3D-based. This application will be more attractive, and the users can use it interactively.Keywords: 3D-based interactive multimedia, education, solar system and exoplanet, technology development.

Abstract

Disease is an unwanted problem in freshwater fish cultivation. Lack of information to prevent the disease and limited number of expert in the field of fishery cause unoptimal harvest that leads to substantial loss. Based on that background, expert system to diagnose disease in freshwater fish cultivation is made in this research. This system is intended to help the fish cultivator in identifying diseases based on the symptoms that the fish have. Therefore, further treatment can be applied to cure the fish. The expert system is web-based with php and MySQL as the programming languages that are used as database. Forward chaining is used as the method of reasoning. This method is used to decide which rule is going to be executed, then it is executed. The process is repeated until the result comes up. This system is able to diagnose 33 diseases in 5 kinds of fish. There are 2 tests in this research which are internal and external. The result of the test shows that the system is able to diagnose well and meet the expectation. Moreover, on the management of the rule, the system is able to run as it is intended. This research has created a web based expert system application that can be used to diagnose diseases based on the facts given and give solutions like an expert.Keywords: Expert System, forward chaining, freshwater fish disease, freshwater fish cultivation.

Abstract

Information can be kept secure by an encryption process in cryptography technique. In this research we discussed comparative analysis of symmetric algorithms: Tiny Encryption Algorithm (TEA) and LOKI in terms of their complexity, time and speed performances. The testing was conducted using 30 data with size varies between 50 bytes and 1500 bytes. Thirty data were tested 50 times. The result shows that TEA is faster in encryption and decryption compared to LOKI  and the complexity of both algorithms are linear algorithms (O (n)).

Abstract

Cocoa (Theobroma cacao L) is one of the plantation commodities that get serious attention because its role is quite high in the national economy. Lampung Province is one of the central cocoa plantations in Indonesia. Cacao cultivation is widely inseparable from a variety of obstacles such as pests and plant diseases. Identification of pests and diseases with various symptoms found in cocoa plants and knowing how to control it is difficult for us, especially farmers in the areas to solve the problem quickly and accurately. Limitations of an expert make handling of pests and diseases of cocoa plants to be difficult, therefore required an expert system that is able to identify pests and diseases in cocoa plants and how to control it based on the knowledge provided by an expert who is able to identify pests and diseases of cocoa and how to control it . This research applied the calculation method of Theorem bayes to calculate the percentage of value. The calculation result is a percentage value and the user can directly see the way pest and disease control are identified. Testing of this research using method Black Box Equivalence Partitioning (EP). Testing questionnaires are divided into 2 variables: user friendly variable and interactive variable. Tests of user friendly variables obtained an average rating of 87.6% and interactive test variables obtained an average rating of 87.52%. With the test results the system shows this app is feasible to use.

Abstract

AbstractThe increase of number and size of data, resulted the increase in the user needs for the ability of a computer to process large data. The new paradigm, parallel computing, is proposed to handle the problems which teaches that substantial-job can be split up into marginal-job by increasing the number of workers. One of the method is cluster computing which is using more than one processor to handle single process. Even it showed a significant increase in computing than the conventional one, the high price to build a cluster system becomes a constraint.This study uses one of parallel computing method that is GPU computing and compares the result to cluster computing. GPU computing uses Graphics Processing Unit (GPU) to compute in parallel. The result of this study shows that by using GPU computing the use of processor can be maximized, and it shows that it has more capability in matrix multiplication than cluster computing.
