Abstract

The increasing demand for eco-friendly materials in the textile industry has led to greater attention on the use of natural fibers, such as pineapple leaf fiber (PALF), which is abundant as agricultural waste. However, its coarse structure and limited spinnability pose challenges in yarn manufacturing. This study aims to compare two fiber blending methods, sliver blending using a drawing frame and fiber blending using a blowing machine in the production of PALF-cotton hybrid yarns via an open-end spinning system. Both samples were prepared using a 50:50 PALF-cotton ratio and evaluated for yarn count, tenacity, and elongation. The results showed that the yarns blended through the blowing process demonstrated superior tenacity and more consistent yarn count. Statistical analysis using an independent sample t-test confirmed that these differences were significant (p 0.05). Elongation values were also significantly higher in yarns processed using the blowing method. These findings highlight the importance of blending technique in improving fiber distribution, inter fiber cohesion, and overall yarn quality. It can be concluded that the blowing method offers a more effective strategy for producing sustainable PALF-cotton hybrid yarns, suitable for industrial scale applications. This research contributes to the advancement of sustainable textile processing and provides a practical reference for industries seeking to utilize agro waste fibers in yarn production.

Abstract

This study systematically examines the challenges of criminal law in upholding justice for social media-based crimes. Social media has evolved into a digital public space that facilitates various forms of crime, from fraud and hate speech to online gender-based violence, to organized crime and digital radicalism. The rapid, anonymous, and transnational nature of these crimes poses serious challenges for criminal law, which still relies on conventional paradigms. This study uses a normative legal approach enriched by socio-legal and digital criminology perspectives. Data were obtained through a literature review of laws and regulations, academic literature, and policy studies related to social media crimes. Qualitative analysis was conducted by examining the suitability of legal norms, law enforcement practices, and the influence of social media dynamics on the criminal justice process. The results indicate that upholding justice for social media crimes faces normative, institutional, and technical challenges. Limited legal norms, gaps in the capacity of authorities, the complexity of digital evidence, and pressure from public opinion through the phenomenon of viral justice affect the objectivity and consistency of law enforcement. The virality of cases has been shown to have the potential to shift the orientation of justice from substance to symbolism. This study concludes that criminal law needs to be developed adaptively and integratively to respond to social media-based crimes. Policy reform, institutional capacity building, and a balance between due process and the demands of the digital public sphere are essential prerequisites for achieving fair and sustainable justice enforcement. This approach is expected to maintain the legitimacy of criminal law in a digital society that is constantly changing critically and sustainably.
