Abstract

Abstrak. MThis study aims to describe the phenomenon of toxic friendship among late adolescents at University X, Badung, Bali. A toxic friendship is an unhealthy relationship characterized by manipulative and domineering behavior, a lack of empathy, and prolonged emotional pressure. This study employs a qualitative approach using the phenomenological method to explore the subjective experiences of students aged 18–21 who have experienced psychologically harmful friendships. Data were collected through in-depth interviews and observations of four primary informants and supporting informants. The results of the study indicate that toxic friendships arise due to low self-confidence, excessive emotional attachment, social pressure, and academic demands. The impacts felt include stress, social anxiety, overthinking, decreased enthusiasm, loss of motivation to study, and even the desire to withdraw from social environments or drop out of college. These findings emphasize the importance of awareness of healthy boundaries in friendships and the need for educational institutions to support the creation of a positive social environment to maintain students' psychological well-being.

Abstract

The productivity of red chili cultivation highly depends on the quality of seeds used by farmers. However, identifying superior red chili seeds is often difficult, leading to low yields and even crop failure. This study aims to design a Decision Support System (DSS) for selecting superior red chili seeds using the SMARTER (Simple Multi Attribute Rating Technique Exploiting Rank) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods. The SMARTER method is applied to determine the weight of each criterion based on the Rank Order Centroid (ROC), while the TOPSIS method is used to rank alternative seed varieties. Seven criteria were considered: price, disease resistance, harvest time, fruit length, fruit weight, number of branches, and yield potential. The system was developed using a waterfall model and implemented in a web-based application with PHP and MySQL. The results showed that the best-ranked alternative was the Tangguh F1 variety with a preference value of 0.7429, followed by Kastilo and TM999. The developed DSS provides structured, efficient, and transparent recommendations, thus helping farmers and agricultural agencies in decision-making for selecting superior red chili seeds.
