The phenomenon of Fear of Missing Out (FoMO) has emerged as a significant psychosocial factor influencing the consumption behavior of Generation Z in the social media era. This study aims to explore how FoMO shapes the purchasing decisions of Generation Z using a qualitative approach, focusing on subjective experiences, digital social pressures, and interactions with viral content. A descriptive-interpretative qualitative method was employed, collecting data through in-depth interviews and observations of social media activity among Generation Z respondents actively engaged in digital platforms. Thematic analysis was applied to identify patterns of FoMO experiences and their impact on purchasing decisions. Findings reveal that FoMO arises from the need for social connection, social comparison with peers and influencers, and intensive exposure to digital trends. This phenomenon drives consumptive behaviors, particularly impulsive purchases, influenced by social validation and emotional impulses. Generation Z’s purchasing decisions are contextual, multidimensional, and not entirely rational, yet meaningful within the framework of digital social identity. The study underscores the necessity of a qualitative approach to comprehensively understand the psychological, social, and cultural complexities of FoMO and consumer behavior. The results provide a conceptual foundation for ethical and relevant marketing strategies targeting young consumers in the digital era.

This study highlights the importance of structured and contextual morphology instruction to improve the quality of vocational students’ PKL report writing.

Project scheduling is an important element for shipyard companies to gain more profit. The most frequently used analysis is the Critical Path Method (CPM). However, in reality, planning using the CPM method is considered less efficient because it does not consider the productivity of each job in it and adds safety time which causes the project duration to become longer. In accordance with the above problems, a new method for planning project schedules is now being developed, namely Critical Chain Project Management (CCPM). CCPM is a project planning method that emphasizes the resources needed to carry out existing tasks in the project. This method is carried out by eliminating multitasking, student syndrome, Parkinson's law and providing a buffer at the end of the project. In this final project, a comparison of the duration of the results of applying the CCPM method with the Critical Path Method (CPM) method is carried out in a case study of ship repairs at PT. Galangan Kapal Madura. The initial project scheduling uses the traditional method in the form of a Gantt chart which is then broken down in more detail and completely with the relationship between activities in the form of CPM, and then will be compared with the duration of the results of CCPM scheduling which has eliminated multitasking, eliminated Safety time for each activity and provided a buffer in the work.

This study evaluates the effectiveness of the SOSEK MALINDO (Malaysian-Indonesian Socio-Economic) regional collaboration program in addressing human trafficking, coordinated by the Regional Border Management Agency (BPPD) of the Riau Islands Province (Kepri). The Riau Islands Province, which borders Malaysia and Singapore, is a strategic entry point vulnerable to transnational crimes, including human trafficking. The main factors driving the people of Kepri to choose illegal routes to become Indonesian Migrant Workers (TKI) to Malaysia are economic pressure, limited job opportunities, attractive promises from brokers (tekong), complex and expensive official bureaucracy, and a lack of accurate information about official procedures. This situation is exploited by human trafficking networks through hidden routes, illegal ports, and methods of illegal labor and sexual exploitation. Although SOSEK MALINDO aims to improve the socio-economic welfare of communities in border areas and indirectly functions to reduce vulnerability to human trafficking, this program does not specifically make human trafficking its main focus. The BPPD plays a very important role as a liaison in cooperation with the Indonesian National Police, Immigration, and BP3MI for prevention and supervision. However, the BPPD faces challenges such as limited funding, overlapping authority between institutions, and a lack of accurate data on human trafficking. Strategic recommendations include making human trafficking a primary focus of the SOSEK MALINDO forum agenda, establishing a dedicated cross-border human trafficking task force, strengthening the BPPD's role in coordination and information gathering, and involving local communities, NGOs, and international organizations in mitigation efforts.
