The rapid growth of cosmetic industry give an opportunity for companies to acquire and engage consumers by using a new e-commerce paradigm called social commerce (s- commerce). One of the most prominent s-commerce among Gen Y is Instagram as this social networking site enables users to browse online stores through its visual interface via mobile device. They are also used to online shop through this platform. Recent researches have shown interests in investigating factors that affect the online shopping behavior in social networking sites but very little is done to understand the process of online buying decision, notably Instagram. In this study, the data were collected by interviewing four participants who have experienced the buying of lip product through Instagram. Online buying decision process framework by Karimi (2013) was adapted for this purpose. The interview was carefully transcribed and analysed using qualitative content analysis (Mayring, 2000). The result of this study shows that the process of online buying decision process on Instagram differs from e-commerce or other social networking sites (SNSs), in terms of how they function this SNS as a platform to search and make buying decision. Major factors affecting its process are habitual Instagram usage and trust to Instagram storeowners. The result also signifies consumers impulse buying tendency. As there is no adequate research on this phenomenon, consumer behavior implications and further research directions are discussed in this study. Keywords: Online Buying Decision, Instagram, Gen Y

This study aimed to identify the correlation between the volunteering on Pemberdayaan dan Kesejahteraan Keluarga (PKK - Empowerment and Family Welfare) and subjective well- being (SWB). Participants of this study were 78 women who volunteered at PKK organization, in TDU Urban-Village, Jakarta. Researchers argued that the higher rate of volunteering in PKK would increase the subjective well-being of women as volunteer at PKK. Data was collected by using the SWB questionnaire and hours of participations per week. SWB was differentiated as life satisfaction and happiness. The results showed that there were insignificant correlations between the hours of participation with life satisfaction (r = -.049, p = .335>.05) and happiness (r = -.060. p = .302>.05). Previous studies stated being a volunteer increased SWB because the volunteers could channel their help through voluntary activities, thus they felt they had contributed to social welfare and increased their SWB level. Participants in this study lived closely with their relatives; therefore they were able to channel their help by taking care of their grand-child instead. Life satisfaction and happiness of the participants were high. In accordance with the results, researchers suggested to evaluate PKK’s programs to meet the SWB of volunteers.
