Disability is a person's condition in the physical, intellectual, mental, and/or sensory limitations in the long term. This study is reserved for those who do not have the lower arm in order to operate the computer normally. This study uses orientation sensor on the smartphone as the main sensor to move the cursor and click. Delivery of data from smartphone to computer is using Bluetooth. This study will compare two gestures from a combination of orientation sensors on the upper arm: gesture 1 using pitch-yaw motion and gesture 2 using pitch-roll motion; to move the cursor on the monitor. Left-click and right-click using ANN is to detect upper arm jerk movements. Evaluation using ISO/TS 9241-411 standard: ergonomics of human-system interaction; which includes performance evaluation and comfort of the gesture. Performance results of throughput, movement time, comfort and fatigue between gestures were not significantly different between those gestures. The result of the effort questionnaire is that gesture 1 has the highest effort on the shoulder and gesture 2 has the highest effort on the hand.

Batik Surakarta has characteristics that not everyone understands, the difference in characteristics lies in the design characteristics, primary colors, and motifs. Surakarta's traditional batik designs and motifs have cultural values that are worth preserving. The combination of the otsu method and the canny method is used to build an application system to improve the results of identifying traditional Surakarta batik images, characteristic features, and shapes of batik patterns. Segmentation is done by partitioning the image into the object area using otsu and determining the boundary of the object using canny to get the characteristics of the image. The results of segmentation processed by selecting and extracting features by selecting quantitative information from existing features using the GLCM method. The characteristics taken are energy, homogeneity, correlation, and contrast. The results of the four characteristics classified into seven Surakarta batik classes, namely Kawung motif, Sido Mukti motif, Truntum motif, Sawat motif, Satrio Manah motif, Parang motif, and Semen Rante motif. The data used are 100 image data, which divided into 70 training data and 30 test data. The results showed that the accuracy rate was 93%.

Flood is one of the disasters that have a big impact in Indonesia. Flooding can affect social, economic, agricultural aspects, etc. Flood disaster is a difficult thing to avoid, the best approach is to reduce the impact caused. Research on flood mitigation began to move to an artificial intelligence approach to providing information on early warning systems (EWS). EWS is a series of systems that function to inform of the occurrence of natural events in the form of floods that will notify the disaster-related floods that will occur. This research will build an intelligent system for building the EWS system. A smart AWS certainly requires various sensors to collect data for later analysis. One of the most important sensors to the construction of the EWS system is the automatic water level recorder (AWLR) sensor. In this paper will specifically discuss the design stages of the AWLR in conducting water level monitoring at the water-gate dam. The function of AWLR sensor is for monitoring and recording in a database with real-time sensing. The results of this research show that the low-cost AWLR sensor has reduced processing time by 92.7% compared to conventional data processing.

A pointing device is one of the important interfaces between human and computer. A mouse is usually used as a pointing device; however, people with physical impairments who can not use a mouse due to its operation should use a table. One candidate for solving this problem is using an upper-arm movement combined with an inertial measurement unit sensor. The upper-arm gestures would be mapped and used to manipulate the mouse cursor on the monitor display. The `clicking' action will be accomplished using a bending sensor attached on the opposite upper-arm. This study evaluates the combination of the IMU and bend sensor (IMU+Bend) as a substitute for the mouse. The evaluation is based on ISO/TS 9241-411: Ergonomics of human-system standard. The results mentioned that the use of IMU is a promising way to emulate the movement of cursor. However, the usage of bend sensor is uncomfortable when it is used as a clicking method. The throughput of the proposed is 1.75 bps, and qualitative results show that the mean of comfort is 4.85 on a Likert scale ranged from 1 to 7.

Augmented Reality is a technology that aims to combine digital content made by computers with the real world in real time. Augmented Reality can be applied in almost all areas of life. One of the applications is in the field of providing information. The publication of registration flow for entrance examination at State Polytechnic of Sriwijaya is still using paper media that makes it less interesting on the prospective applicants. Therefore it requires an application based on android to implement the information distribution of registration flow for entrance examination at State Polytechnic of Sriwijaya. This augmented reality application consists of two menus namely information menu and location menu. Information menu contains motion graphic video of registration flow for entrance examination at State Polytechnic of Sriwijaya and location menu contains 3d object of entrance examination at State Polytechnic registration buildings. The research method is divided into several stages, namely design, asset creation, implementation and testing. At the testing stage is divided into two, namely application testing by testing the functionality of the features provided by the application and testing of respondents to determine the effectiveness of registration flow at State Polytechnic of Sriwijaya compared to paper media seen in the respondent's answer of 88.7%.

Some disabilities caused by sensory malfunction, accident, or congenital disorder could cause people difficulty in grasping the computer mouse. A well-known substitute uses an inertial sensor to monitor the body's orientation. This paper evaluates the efficiency and effectiveness of different methods of holding the sensor. There are two modes of holding the sensor, the grasping mode and the attached mode;we also evaluate a mouse as a baseline. The attached mode works by placing the sensor on the back of user's hand. The quantitative and qualitative evaluation procedure is based on ISO/TS 9241 part 411: Ergonomics of human-system interaction standard. The test consists of four levels of difficulty and indicates that the throughput and task completion times were not statistically different between grasping and attached mode. We also found that grasping mode and attached mode did not show significantly statistical differences in comfort and fatigue based on the questionnaires. The results also suggest that the orientation of the hand used in grasping and attached modes is suitable only for lower-impact computer use. © Published under licence by IOP Publishing Ltd.
