Third Culture Individuals (TCIs) are individuals who spent a significant part of their developmental years outside of their passport country, often associated with having cultural intelligence and intercultural communication competence. While TCIs are naturally exposed to various cultures as a result of their mobility, non-TCIs do not necessarily share the same traits and experiences growing up. However due to globalization this may no longer be the case and may perhaps be the reason why despite the differences, TCI and non-TCIs are similar in some way. TCIs are known for their ability to be accepting of different cultures; a characteristic often associated with cultural intelligence, from this it can be assumed that TCIs have a higher level of Cultural Intelligence than non-TCIs. So far there hasn’t been sufficient research regarding TCIs in general, which also applies in theIndonesian context. This study compares the level of Cultural Intelligence of both Indonesian TCIs and non-TCIs through a quantitate research using the Cultural Intelligence (CQ) scale thatmeasures four dimensions; metacognitive, cognitive, motivational and behavioral. Data in this research were gathered from an online survey, from a total of 140 Indonesian TCI and non-TCI respondents that are currently living in Indonesia. Results showed that TCI samples have a higher level of Cultural Intelligence than non-TCIs, with motivational CQ being the dimension scored highest for both TCI and non-TCI samples.

There are many factors that can lead to internship satisfaction. Working environment is one of the factors that will result to such outcome. However, many organizations discarded the fact of its importance. The purpose of this study is to determine whether there is a significant relationship between working environment and internship satisfaction level as well as to determine whether the dimensions of working environment significantly affect internship satisfaction. The said dimensions are, learning opportunities, supervisory support, career development opportunities, co-workers support, organization satisfaction, working hours and esteem needs. A total of 111 questionnaires were distributed to the respondents and were processed by SPSS program to obtain the result of this study. The results reveal that learning opportunities, career development opportunities, organization satisfaction and esteem needs are factors that contribute to internship satisfaction level. In the other hand, supervisory support, co-workers support and working hours are factors that lead to internship dissatisfaction. The result also shows that organization satisfaction is the strongest factor that affects internship satisfaction while co-workers support is the weakest.

With the increasing number of restaurants being opened annually, restauranteurs can not only pay attention to the food and service, but also to the restaurant’s physical atmosphere. This study focuses on DINESCAPE as the theory for physical environment. It aims to find whether or not the factors of DINESCAPE affect customer repurchase behavior in an upscale restaurant. This is a quantitative descriptive research and uses questionnaires to obtain its data.132 data from questionnaires are obtained from customers that have dined at Restaurant X. Restaurant X is an upscale restaurant located in the heart of Jakarta. Multiple linear regression isused to analyze the data and obtained the result. Result shows a strong relationship of 67,9% from physical environment towards customer repurchase behavior. Each hypothesis regarding the factors of DINESCAPE are accepted and shows that each factor of DINESCAPE affect customer repurchase behavior. Based on the findings, recommendations for Restaurant X include, but not limited to, improving the restaurant facility aesthetics such as lighting and themed decorations to stimulate repurchase behaviours.

Online hotel reviews is an important source for customers to find out the products and service quality. Online hotel reviews consist of reviews and ratings. The best online reviews website in TripAdvisor. In this era, online reviews are really important and could affect customer preferences in choosing a hotel. The aim of this research is to analyze in what extent do online reviews and ratings affect customer preferences. This study use survey by distributing a total of 100 questionnaires in order to gain the data. Then, the data will be proceed through SPSS to test the validity, reliability, classical assumption, and multiple regression analysis. The results indicatedthat both of the variables (online reviews and ratings) positively impact customer preferences in choosing a hotel. However, online reviews has a bigger impact towards customer preferences rather than online ratings. It is recommended for TripAdvisor to weed out the fake reviews and guarantee the trustworthy reviews. For the hotel managers, it is recommended to response both, positive and negative reviews that made by customers in TripAdvisor, because it could change someone’s perceptions into the good feeling of the hotel.

This research proposed a model to assist the design of the associated data architecture and data analytic to support talent forecast in the current accelerating changes in economy, industry and business change due to the accelerating pace of technological change. The emerging and re-emerging economy model were available, such as Industrial revolution 4.0, platform economy, sharing economy and token economy. Those were driven by new business model and technology innovation. An increase capability of technology to automate more jobs will cause a shift in talent pool and workforce. New business model emerge as the availabilityand the cost effective emerging technology, and as a result of emerging or re-emerging economic models. Both, new business model and technology innovation, create new jobs and works that have not been existed decades ago. The future workers will be faced by jobs that may not exist today. A dynamics model of inter-correlation of economy, industry, business model and talent forecast were proposed. A collection of literature review were conducted to initially validate the model.

As violence shown in films steadily increases, notably in those targeted towards the teenage audience, this research looks into its effect specifically by observing the change in audiences’ hostility. An experiment was done on 125 Indonesian secondary school students to observe the effect of exposure to media violence on their feelings of hostility, measured using Anderson’s State Hostility Scale (1995, 2012). Students’ hostility scores were measured beforeand after being exposed to an assigned clip; either a violent clip, or an equally exciting but non-violent clip as a control group. Results showed that those in the violent condition were significantly more hostile after watching than before watching, and those in the violent condition were significantly more hostile post-exposure than those in the non-violent condition. Out of the four dimensions of hostility, the dimension ‘Lack of positive feelings’ was significantly highest in both conditions, and only the dimension ‘Aggravation’ significantly differed between the two conditions. These findings indicate that exposure to media violenceraises teen audiences’ hostility levels significantly, which implies that further precaution should be taken when exposing teens to certain film content which has significant immediate effects ontheir moods, while also raising the issue of its potential long-term effects, should this exposure be continuous.

The goal of this research is to detect Surface Electromyography (SEMG) signal froma person’s arm using Myo Armband and classify his / her performed finger ges-tures based onthe corresponding signal. Artificial Neural Network (based on the machine learning approach)and Principal Component Analysis (based on the feature extraction approach) with and withoutFast Fourier Transform (FFT) were selected as the methods utilized in this research. Analysisresults show that ANN has achieved 62.14% gesture classifying accuracy, while PCA withoutFFT has achieved 30.43% and PCA without FFT has achieved 48.15% accuracy. The threeclassifiers are tested using SEMG data from a set of six recorded custom gestures. Thecomparison results show that the ANN classifier shows higher classifying accuracy and morerobust rather than the PCA classifier’s classi-fying accuracy. Therefore, ANN classifier is moresuited to be implemented in classifying SEMG signals as hand gestures.

In this research the potential of Pakoba leaf extract to be used as antioxidant and skin whitening (anti-melanogenic agent) is investigated. The antioxidant activity of Pakoba leaves were studied using DPPH method and the result showed that the 80 percent methanol crude extract has strong antioxidant activity with an IC50 value of 22.66 ± 1.02 μg/ml. The aqueous fraction of the sample has an IC50 value of 53.30 ± 1.42 μg/ml, followed by n-butanol fraction (53.63 ± 1.45 μg/ml) and chloroform fraction (511.54 ± 1.59 μg/ml). The anti-melanogenic activity of the crude methanol extract showed IC50 value of 316.56 ± 11.04 μg/ml. Thus, it isconcluded that crude extract of Pakoba leaves shows good potential as the antioxidant source although it does not show good anti- melanogenic activity.
