Abstract

This study aims to analyze Generation Z's digital reading literacy skills in identifying hoaxes in the digital era, where information spreads rapidly across various platforms. Employing a qualitative approach with descriptive analysis methods, this research involved 74 respondents from Generation Z, born between 1997 and 2012. Data were collected via a questionnaire to evaluate their understanding and practices regarding hoax news. The research findings indicate that 98.6% of respondents are aware of hoaxes, and 89.2% verify information before accepting it. However, only 64% feel confident in their ability to assess the credibility of information sources. Social media, particularly WhatsApp and TikTok, were identified as the main news sources, which potentially increases the risk of exposure to inaccurate information. These findings indicate a gap between awareness and evaluative skills possessed by Generation Z. Therefore, developing more comprehensive digital literacy programs in schools and communities is deemed necessary to enhance their critical abilities in confronting potentially misleading information. This study proves that without adequate digital reading literacy skills, Generation Z is at risk of being caught in the tide of misinformation that could influence political views, health perspectives, and other social issues.

Abstract

The textile industry requires innovation in the use of dyeing materials that are not only effective but also environmentally friendly. One potential source of natural dyes is noni root (Morinda citrifolia), which contains anthocyanin and morindone compounds as coloring agents. This study aims to examine the effect of immersion duration on the color strength of cotton fabric dyed with natural dye extracted from noni root (Morinda citrifolia). The dye extraction was carried out using two methods: heating (batch) and maceration with methanol as the solvent. The dyeing process included mordanting, dyeing with varying immersion duration (8, 16, 24, 32, and 40 hours), and fixation. The results showed that longer immersion duration increased amount of dye bound to the fabric in both extraction methods. Color fastness tests produced results categorized as poor (2–3/2.5), fair (3.0), and good (4/4–5/4.5). These findings indicate that natural dye extracted from noni root can be used as an alternative natural dye for textiles, particularly cotton fabric, with sufficient color stability.

Abstract

Kulit buah naga super merah memiliki kandungan antosianin dan pektin yang dapat digunakan sebagai bahan alternatif alami pada produk olahan pangan. Selain itu di Indonesia terkenal dengan penghasil rimpang jahe yang memiliki rasa serta aroma yang bervariasi, salah satunya jahe merah. Perkembangan produk pangan semakin inovatif, salah satu pemanfaatan kulit buah naga yaitu dengan cara pembuatan permen jelly dengan penambahan sari jahe merah. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh serta konsentrasi terbaik dari ekstrak kulit buah naga super merah dengan variasi sari jahe merah utuk memperbaiki mutu pada permen jelly. Penelitian ini menggunakan metode eksperimental yang terdiri dari 9 perlakuan yaitu konsentrasi ekstrak kulit buah naga super merah 20%, 30%, dan 40%, serta sari jahe merah 0%, 3% dan 6% dengan parameter uji organoleptik, uji kadar air, uji kadar abu dan uji gula reduksi. Hasil analisis didapat perlakuan terbaik pada konsentrasi 40% ekstrak kulit buah naga super merah dan 3% ekstrak jahe merah, dengan menghasilkan nilai kesukaan pada uji organoleptik indikator warna dengan nilai 3,00, parameter rasa dengan nilai sebanyak 2,46, parameter tekstur dengan nilai 2,70, dan parameter aroma dengan nilai 2,86 sedangkan untuk uji kadar air sebesar 4%, uji kadar abu sebesar 0,05% dan uji kadar gula reduksi sebesar 8,13%.

The Cireundeu village indigenous community is a society that is obedient in carrying out ancestral mandates. One of the behaviors passed down by the ancestors of the Cireundeu Village Indigenous Community to the residents as the next generation is the habit of consuming rasi (cassava pulp rice) as a staple. This research aims to provide an overview of the life of the Cireundeu Indigenous Village Community in a cultural perspective. The method used in this research is descriptive qualitative with observation, interview, and literature study techniques. The results of this study indicate that the Cirendeu Traditional Village Community has a rich culture and a strong social system. This encompasses a variety of aspects, including living equipment, livelihoods, kinship systems, languages, arts, knowledge, and religion. While the indigenous people of Cirendeu Village uphold the customs passed down by their ancestors, in terms of life, the Cireundeu indigenous people are also not much different from ordinary people. They carry out social life, socialize, and even attend school.
