The rapid growth of digital marketplaces has significantly reshaped consumption behavior among university students. Promotional strategies based on scarcity and urgency, such as flash sales, limited-time discounts, and countdown timers, are designed to induce psychological pressure, potentially triggering Fear of Missing Out (FoMO). This study aims to examine the relationship between self-control and FoMO among university students who use digital marketplaces. A quantitative correlational design was employed, involving 70 undergraduate students selected through accidental sampling. Self-control was measured using the Brief Self-Control Scale, while FoMO was assessed using an adapted Online FoMO Scale. Data were analyzed using Pearson’s product-moment correlation after fulfilling normality assumptions. The results revealed a significant negative relationship between self-control and FoMO (r = –0.522, p < .001), indicating that individuals with higher self-control tend to experience lower levels of FoMO in marketplace contexts. These findings highlight the role of self-regulation as a protective factor against emotionally driven consumption behavior. This study contributes to the literature on digital consumer psychology by extending the concept of FoMO beyond social interaction into economic decision-making contexts. Strengthening self-control is therefore essential in helping individuals manage psychological pressure arising from urgency-based marketing strategies.

The flash flood disaster that hit Indonesia, including the devastating disaster in three Sumatran provinces in November-December 2025 which resulted in more than 900 casualties and trillions of rupiah in losses, shows a strong correlation between environmental damage caused by corporate activities and increased disaster risk. The purpose of this study is to analyze corporate criminal liability for environmental damage resulting in flash flood disasters based on the Environmental Management Law (UU PPLH), examine the mechanism for proving corporate criminal liability, and evaluate the application of criminal sanctions against corporations that commit environmental damage resulting in flash flood disasters. The research method used is normative legal research with a descriptive analytical statute approach. Data collection techniques are carried out through library research and interviews with sources at the North Sumatra Provincial Environmental Service. The data obtained were analyzed qualitatively. The results of the study indicate that: First, corporate criminal liability for environmental damage resulting in flash floods has been comprehensively regulated in Articles 116 to 120 of the Environmental Management and Management Law, which recognizes corporations as subjects of criminal law and regulates the criteria for corporate crimes (committed by, for, or on behalf of a business entity), the responsible party (the business entity and/or the person giving the order/leader of the activity), a one-third aggravation of the sentence, and corporate representation in court, as reinforced by Supreme Court Regulation Number 13 of 2016. The conclusion of this study is that the Environmental Management and Management Law has provided a comprehensive legal framework for corporate criminal liability for environmental damage resulting in flash floods. However, the effectiveness of law enforcement still needs to be improved through accelerating the judicial process, strengthening the capacity of law enforcement, improving inter-agency coordination, and strengthening the decision execution mechanism.

The oil and gas industry plays a crucial role in meeting global energy needs, with crude oil from production wells being the primary product of upstream operations. Prior to further processing, crude oil requires pretreatment at the production site, one of the key stages being phase separation using a flash separator. This study examines the effect of variations in cooling temperature on the performance of liquid phase separation and energy requirements in the flash separation process of light hydrocarbons. The analysis was conducted through process simulation using Aspen HYSYS version 14.2 with the Peng Robinson property package. The feed stream had a mass rate of 10,000 kg per hour, a temperature of 50°F, and atmospheric pressure, with compositions of ethane, propane, isobutane, and normal butane. The process configuration included compression, cooling, and phase separation in a flash separator at a constant pressure of 50 psia. Variations in cooling temperature were applied at 20, 10, and 0°C. The simulation results indicated a thermodynamic critical point at 10°C. At 20°C, no liquid phase was formed, while at 10°C, significant liquid yield was obtained with moderate energy consumption. Lowering the temperature to 0°C dramatically increases liquid recovery, but the cooling energy requirement also increases sharply. Sensitivity analysis confirms a strong inverse relationship between temperature and condensation yield, as well as a surge in energy consumption at low temperatures. The optimal operating condition is set at 10°C, providing a balance between separation efficiency and energy efficiency in accordance with sustainable manufacturing principles.

The flash floods and landslides that occurred in Central Aceh and Bener Meriah Regencies demonstrate that disaster issues are not only related to natural factors but are also influenced by community social communication patterns. This study aims to analyze disaster communication based on local wisdom to improve preparedness, emergency response, and recovery of disaster-affected communities. The study used a qualitative approach with a case study method. Data collection was conducted through in-depth interviews with traditional leaders, religious leaders, village officials, and affected communities, as well as field observations and documentation studies. The results indicate that the local wisdom of the Gayo community, such as the role of the village reje, mosque imam, customary deliberations, and the value of maintaining natural balance, serves as an effective and trusted disaster communication medium. However, this local wisdom has not been optimally integrated into the formal disaster communication system of the local government. This study recommends strengthening the synergy between modern communication and local wisdom as a sustainable and contextual disaster communication strategy.
