High dimensional problems are often encountered in studies related to hyperspectral data. One of the challenges that arise is how to find representations that are accurate so that important structures can be clearly easily. This study aims to process segmentation of hyperspectral image by using swarm optimization techniques. This experiments use Aviris Indian Pines hyperspectral image dataset that consist of 103 bands. The method used for segmentation image is particle swarm optimization (PSO), Darwinian particle swarm optimization (DPSO) and fractional order Darwinian particle swarm optimization (FODPSO). Before process segmentation image, the dimension of the hyperspectral image data set are first reduced by using independent component analysis (ICA) technique to get first independent component. The experimental show that FODPSO method is better than PSO and DPSO, in terms of the average CPU processing time and best fitness value. The PSNR and SSIM values when using FODPSO are better than the other two swarm optimization method. It can be concluded that FODPSO method is better in order to obtain better segmentation results compared to the previous method.

The work course at Ahmad Dahlan University's Informatics Engineering is a course that aims for students to go directly or get projects related to technology development. One of the creative courses that students must take in semester 6 is Information Technology Project Management (MPTI), where the course is conducted in groups. Processing of final grades from MPTI courses from 3 components, namely supervisors, examiners and industry supervisors (partners). Because the value components are from various sources, a system is needed to process all processes from registration to processing the final value. The agile development method is a development method that prioritizes input from partners as users, besides that the agile method has advantages including fast, adaptive, iterative. The model used in system development in agile is the Dynamic Systems Development Method. Data collection was done by literature study, observation, and interviews. The system development stage using an iterative model includes the needs analysis stage, the design stage, the implementation stage, the testing stage, and the evaluation stage. Implementation using the PHP programming language and the Laravel framework. Testing is done black box test. The results of the research produced an information system and tested. Tests carried out using a black box test which resulted in 82,76%

Cloud computing is a service that eases its users to store data on the internet. However, cloud computing has lack, which is related to stored data security specifically to image file that can be manipulated easily. To improve the data securities of JPG file type on cloud computing, the combination of advanced encryption standard (AES) cryptography and least significant bit (LSB) steganography methods is required. This study implemented AES 128 algorithm cryptography process to scramble the messages that will be inserted and LSB steganography to hide the messages that has been scrambled. The data were assessed using Stegspy. The results of this study indicated that cloud computing service of Platform as a Service (PaaS) has resulted ciphertext that was attached to JPG/JPEG images using Least Significant Bit (LSB). From 5 (five) samples, the encryption result testing on JPG/JPEG files was bigger than the original file. The bigger the number of characters of the inserted text, the bigger the size of JPG/JPEG files will be.

Penipuan yang dilakukan melalui website dan blog merupakan kejahatan online yang marak terjadi. Saat ini proses pelaporan masyarakat masih dilakukan dengan mengisi form laporan, sedangkan untuk proses pelacakan dari data laporan masih menggunakan cara mengunjungi website secara satu-persatu, sehingga tidak efektif, maka dilakukan penelitian yang menghasilkan proses dan alur sistem pelacakan kejahatan online dengan memanfaatkan Metode Regex  (Regular  Expression) Dari Grab Google Search Api. Proses  pelacakan menggunakan metode RegEx  (Regular Expression) yang merupakan suatu notasi fleksibel dan ringkas untuk mencari dan menggantikan pola teks. Metode pengumpulan data dengan metode observasi dan wawancara. Tahap analisa proses pelacakan dilanjukan perancangan alur proses pelaporan dan perancangan alur sistem. Dirancang Prototyping halaman pelaporan yang menggunakan metode regex. Hasil penelitan berupa alur sistem pelacakan dengan menerapkan metode RegEx dari grab google search untuk melacak website dan blog dengan keyword berupa alamat website dan nomor handphone. Alur sistem baru lebih mengefektifkan sisi waktu proses pencarian situs penipuan yang di-index oleh google. Masyarakat dapat mengetahui antara website terpercaya dengan website yang dibuat oleh penipu, sehingga masyarakat akan lebih berhati-hati terhadap penipuan.

The schools in Mayodan sub-district have not used information technology with maximum to support learning and education activity. They need assistance in community service to train them to organize learning media using eLearning. The methods of implementing the training are tutorial or assistance, giving a module to participants, workshop and evaluation process. The impact of this training is improvement knowledge in information technology uses. This impact can show from training result. The result showed 74% participants agree and like with this training results.
