Modern philanthropic organizations are responsible for the use of social resources. However, some of them are facing several managerial issues, including inadequate database management and lack of accountability. To support the documenting process and to improve the management of funds, these organizations need a computer-based information management. This qualitative action research using prototyping method aimed at designing a management information system for a philanthropic organization which focus on providing education access for disadvantaged students in Yogyakarta. The process of designing management information system in the case study was applying a prototyping method since not every organization including a philanthropic organization could explicitly define the information needed to support their business process. This prototype was designed based on organization?s requirements so that users can obtain any information needed easily. The management information system prototype could provide assistance for a philanthropic organization in managing and documenting all activities in the organization.

Along with the development of technology and information today, data security is a problem that needs to be done to maintain the confidentiality of data or information both personally and within an organization. Cryptography is one of the sciences or arts that learns about how to secure data or information from irresponsible parties who want to destroy important data in the form of text and image files. This research, data security technique uses two algorithms, namely steganography to enter text in image media using LSB (Least Significant Bit) method and Binary XOR used to convert messages to binary with XOR keywords and generate pixel values of messages from 8 bits of images with LSB (Least Significant Bit). After encrypted the image will be sent to the user, and to view the original data, the user must decrypt the data with the message key and retrieve the LSB (Least Significant Bit) value, from the encrypted image.

Viola Jones method uses the file classifier to object detection. The training process to create object classifier file requires very high computer resources and time which is directly proportional to the amount of training data. The amount of training data determines the accuracy of object detection. The long training process is caused because the computer has low specifications and the distribution of Haartraining files will speed up the process of vector file formation, minimize errors when cutting Haar features on positive objects and also minimize errors that occur during the training process. The problems that arise next are how to overcome this so that a better knowledge is obtained. This study provides analysis results of the process of merging knowledge acquisition and its effect on the accuracy of object detection using the Viola-Jones method with the final result undetected object decrease 52.62% and object detected increase 23.78%

In this paper, computational acceleration of color image segmentation using fuzzy c-means (FCM) algorithm has been presented. The color image is first converted from the Red Green Blue (RGB) color space to the YUV color space. Then, the luma (Y) information values are grouped according to the desired number of clusters using the FCM algorithm. The FCM algorithm is implemented on a Graphical Processing Unit (GPU) using the Compute Unified Device Library (CUDA) library which is developed by NVidia to speed up the computing time. Images used in this research are red blood cell images, geometry images and leaf images. The results of segmented images processed using GPU were seen identic to the results of segmented images processed using the Central Processing Unit (CPU). The computational time of the FCM algorithm can be accelerated by speed-up to 5,628 times faster and the average speed-up of all simulations done is 5,517 times faster.

Information technology that is increasingly developing today must be balanced with the similarity of information data. Information security is obtained by applying cryptographic techniques, Vigenere Cipher is a key symmetry algorithm that uses a substitution technique that uses two letters encoding the original message. Vigenere cipher has a weakness because it uses short keywords and its use will be repeated. In this study, we will discuss the modification of the vigenere cipher algorithm and one time pad by adding a key elongation process as done in the RC6 algorithm. The results of the study will produce new variations in data security by combining the vigenere cipher algorithm and vernam cipher with key expansion algorithm RC6

Since the first election policy was enacted simultaneously, it does not mean that it does not have potential problems, instead it causes other problems, which require extra time and energy in doing recapitulation. Simultaneous elections consist of presidential elections, DPR elections, Provincial DPRDs, City / Regency DPRDs, DPD, the more they are elected, the more influential is the time of voting and the time of vote recapitulation. The longer the voting time is done by the voters, the longer the recapitulation time. The longer time of recapitulation results in the fatigue of KPPS members which triggers inaccurate work and prone to manipulation and fraud so that it can damage the quality of elections. This study aims to determine the estimated time needed for voting for ballots in elections using the Multilayer Perceptron Artificial Neural Network (ANN) approach. The resulting time estimate is based on the time of the voter in the voting booth. The results of this study indicate that ANN with the Multilayer Perceptron Algorithm can calculate the estimated time required for ballot balloting by producing the best combination of learning parameters with 4 hidden neurons, learning rate 0.001, and 2000 epoch iterations resulting in an RMSE value of 108,015 seconds.

Publisher : Sekolah Tinggi Teknologi Adisutjipto Yogyakarta

The development of animation technology is currently very rapid, but to animate a three-dimensional object beforehand must be done by preparing the framework manually. Also in the real world, when two objects collide, they do not penetrate each other. When a collision occurs, the interaction force will change the original state of two objects, such as position, trajectory, and direction. The purpose of this study focuses on the rigid body in a three dimensional rigging model arrangement for car animation scenarios on a bumpy road. This approach focuses on reducing manual movement by animators when animating three-dimensional car models. The result is to make a car animation on a bumpy road well, then the arrangement of the framework on the car has a mass = 1946 kg and gravity = -981.001 cm / s2. As well as knowing the results of the animated motion of the car on a bumpy road with a tolerance of distance between the car's wheels and the trajectory of 4.44 cm without applying a rigid body to the arrangement of the car's frame. While the motion animation of the car on a bumpy road with good results where the tolerance of the distance between the car wheels and the track is 0.045 cm after applying a rigid body to the arrangement of the car's frame.
