<![CDATA[Google is known to still track the user's location despite the GPS settings and location history in smartphone settings has been turned off by the user. This requires special handling to prove the location on smartphones with inactive GPS and view its Location History previously used by user. The research investigates if Google is still recording its user data location. Live Forensic requires data from the running system or volatile data which is usually found in Random Access Memory (RAM) or transit on the network. Investigations are carried out using a Google account with a method used by live forensics to obtain results from the location history. Smartphones have been checked manually through data backup through custom recovery that has been installed. When checking the backup filesystem, turned out that no location data is stored. Therefore, researchers conducted an analysis on the Google Account which was analyzed using a forensic tool to analyze cloud services to obtain location data results. The results of the analysis carried out obtained a similarity in location from 8-days investigations. Google can still find the location of smartphones with GPS disabled, but the location results are not accurate. Google can store user location data via cellular networks, Wi-Fi, and sensors to help estimate the user's location. The process of extracting the results from the google maps log using a Google account will be analyzed using the Elcomsoft Cloud eXplorer and Oxygen Forensic Cloud Extractor so that the log location results are still available by Google.]]>

<![CDATA[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.]]>

<![CDATA[Accurate effort estimation of software development plays an important role to predict how much effort should be prepared during the works of a software project so that it can be completed on time and budget. Some sectors, e.g. banking sectors, were renowned fields of software projects, not only due to its huge size of project, but also extremely expensive and takes a long time to completion. Project estimation is essential for software development project able to run on time and budget with maximum quality. This study aims to investigate the accuracy of software project effort estimation with the Analogy method using three parameters: Euclidean, Manhattan and Minkowski distance. Analogy based estimation consists several stage included similarity measure, analogy adaptation, estimation calculation and model evaluation. The results showed that the best combination of Analogy methods was using Manhattan distance with an accuracy of 50% MMRE, 28% MdMRE and Pred(25) 48%. Thus, we can concluded that this model can be used to predict accurately.]]>

<![CDATA[Human has the ability to think that comes from the brain. Electrical signals generated by brain and represented in wave form. To record and measure the activity of brainwaves in the form of electrical potential required electroencephalogram (EEG). In this study a cognitive task is applied to trigger a specific human brain response arising from the cognitive aspect. Stimulation is given by using nine types of cognitive tasks including breath, color, face, finger, math, object, password thinking, singing, and sports. Principal component analysis (PCA) is implemented as a first step to reduce data and to get the main component of feature extraction results obtained from EEG acquisition. The results show that PCA succeeded reducing 108 existing datasets to 2 prominent factors with a cumulative rate of 65.7%. Factor 1 (F1) includes mean, standard deviation, and entropy, while factor 2 (F2) includes skewness and kurtosis.]]>

<![CDATA[Penelitian ini mengeksplorasi tentang bagaimana korelasi penerapan kognitif ergonomi yang terdapat di beberapa implementasi antarmuka sebuah perangkat lunak maupun website. Antarmuka tersebut diimplementasikan dengan dukungan kecerdasan buatan sehingga tercipta fitur antarmuka yang cerdas atau Intelligent User Interface (IUI). Semakin cerdas fitur yang dipersembahkan lewat antarmuka, ekspektasi yang diharapkan adalah semakin rendah beban kerja mental yang dirasakan pengguna ketika melakukan pekerjaan. Bidang kognitif ergonomi akan dikaji dari segi bagaimana sisi kenyamanan user dalam hal proses mental berpikir saat menggunakan fitur IUI, khususnya yaitu bagaimana pengaruh jumlah informasi di suatu aplikasi berdampak pada sisi kenyamanan pengguna saat berinteraksi dengan antarmuka cerdas. Proses pengambilan data dan pengujian akan dilaksanakan melalui kuesioner yang dirujuk dari studi kognitif ergonomi dengan metode NASA-TLX. Hasil kajian berupa perbandingan hasil beban mental yang dirasakan pengguna saat melakukan interaksi dengan aplikasi yang sering digunakan sehari-hari untuk perkuliahan berdasarkan program studi yang ditekuni di UAD. Frekuensi kerja dengan aplikasi dan tingkat adaptasi teknologi juga diprediksi akan mempengaruhi beban kerja. Hasil akan divalidasi secara kualitatif dari pengujian user experience secara berkelompok. AbstractThis study explores the correlation of cognitive ergonomic applications found in several interface implementations. The interfaces were implemented with the support of artificial intelligence to make it intelligent (Intelligent UI/IUI). The smarter the features provided through the interface, the expected cause is the lower the mental workload that users feel when doing work. The field of cognitive ergonomics will be examined in terms of how user feels convenience in terms of mental processes when using IUI features. The process of data collection and testing will be carried out through a questionnaire referenced from cognitive ergonomics studies using NASA-TLX method. The expected results of the study is a comparison of mental workload felt by users when interacting with applications that are often used daily for lectures based on the study program occupied at UAD. The frequency of work with applications and the level of technological adaptation are also predicted to affect workload. The results will be validated qualitatively from user experience testing in groups.]]>
