Especially crowd control police performance. In certain situations, there is confrontation and violence. A narrative of riots was created, because police clashed with demonstrators. The emotion regulation and their physiological indicators becomes a co-occurring phenomenon in a riot of demonstrations. Police anger in violent demonstration situations needs to be clearly mapped. This study intends to map the dominance of emotion regulation by involving heart rate indicators. Riot demonstration stimulus was given to participants to stimulate aggressive impulses, heart rate was measured when participants watched the video. Research participants come from Crowd Control Police in the Jakarta working area. Research data is tested by correlating emotion regulation with heart rate, provocation, and impulsive aggression. The results found the dominance of emotion regulation to other variables. The pulsating impulse of the riot...

The development of biomechanics has an effect on the field of physiotherapy. Various physiotherapy tests or studies have been developed by researchers to identify and analyze the causes of movement disorders in the human body. Physiotherapy tests performed to detect movement disorders in the human body include: Hawkin Test, Standing Hip Flexion, Standing Trunk Sidebend Test and Straight Leg Raise Test. Straight Leg Raise test is a test to lift one leg straight up in a lying down position. In the medical field, Straight Leg Raise (SLR) movement is very specific for lower lumbar disc herniation and through the use of a device called Kinect which is a color based camera (RGB) and depth camera that can detect movement and track the human skeleton. To get the human body skeleton is through the stages from RGB image acquisition, pose calibration, depth image, skeletonization to feature extraction of the two legs that can form ROM. The result of this study, Kinect is able to track the user's foot frame in SLR pose. Kinect can be relied upon to be used as a tool for detecting and tracking skeletons, and can then be used to measure SLR ROM in real time and analyze low back pain problems and measure effectiveness in physiotherapy.

Facebook, one of the most common social media in Indonesia, provides a platform to spread information throughout its user. However, fact-based information is not the only one circulate on the Internet. The number of fake news shared throughout the Internet, especially social media, is concerning. Investigating fake news requires considerably longer time in collecting the data to compare. In addition, humans naturally are not very good at differentiating between real and fake news [3]. It makes machine learning becomes advantageous in dealing to this problem. However, the rapid changes of news throughout time requires machine learning to be able to train its model dynamically. Incremental machine learning is proposed to solve this problem. As much as 6757 labeled data containing both fake and factual news provided by George McIntire, Politifact, and Buzzfeed are set to ...

Early detection is eficiently performed by using Digital mammograms. This research will be developed methods that can be used to detect abnormality of breast cancer. Step by step to classify normal and abnormal classes on digital mammogram is image acquisition which images are taken from MIAS database, find the region of interest using morphology algorithm, feature extraction using GLCM (Gray Level Cooccurrence matrix) and the last is classification process using SVM (Support Vector Machine). The accuracy of abnormalities (normal or abnormal) on digital mammogram for each testing data used in classification process have a different value, that is 85.00% percentage were taken inside from training data, 60.00% were taken outside from training data and 67.5% were taken inside and outside from training data. From these results, testing data that used in classification process affect on percentage of abnormality accuracy. ...

It is very interesting to see sexual script and sexual double standard on people from different ethnics. Indonesia has many different cultures and ethnics and might have different point of view in sexual script and sexual double standard. The aim of this research is to measure the correlation, contribution, and comparation of sexual script and sexual double standard in Bataknese, Melayunese, Betawinese, and Javanese ethnics. The participants of this research is 205 people collected from Medan, Samosir, Jakarta, Yogyakarta, and Klaten, using insidental sampling. The result shows that sexual script has positive correlation and big enough contribution to the sexual double standard. There is a significant sexual double standard differentiation based on ethnics and confession of had an affair in the past or not, but not in sexual script. There is a significant sexual script differentiation based on educational background. On the other hand, the differentiation of the two variables found based on city they lived in, and gender whereas male has higher score than females. This result show many interesting finding such as the city where participants live has more significant impact in influencing sexual script and sexual double standard than the ethics itself, and marital status has no influence on sexual script and sexual double standard.

While most research has focused on the development of computation algorithm and hardware for its application in new operations, human aspects seemed to be neglected. Inevitably, human's role is increasingly essential, rather than less. Several issues concerning human's roles in Cyber Physical System-based operations in air and land transport and some future directions are highlighted.

The adolescences also tend to share their privacy. This study aims to determine whether extraversion personality, perceived privacy risks, the convenience of maintaining relationships, and online self-presentation influence self-disclosure in adolescents. This study involved 619 adolescents (185 male and 434 female) aged 13-22 years (M = 19.39, SD = 1.83). The participants are active social media users collected from several areas in Indonesia. Multiple regression analysis is used to test the hypothesis. The results show that several variables simultaneously affect online self-disclosure in adolescents (R2 = .422; F (4, 614) = 111.944, p < .01). However, in details, online self-presentation does not have a significant effect on online self-disclosure among adolescents.
