Authors: Widyasari Ida Ayu Made Tania , Masriani Masriani , Hairida Hairida
Published: January 2025

The high demand for the textile industry can pollute the environment through waste. Natural dyes from natural ingredients are used as a step to minimize this waste.  Dayak onions can be used as a natural dye because they produce a red color from anthocyanin compounds. However, natural dyes have weaknesses, namely that the color is less stable and fades easily, so a fixator is needed. Fixator is used to strengthen the color in fabrics that use natural dyes. Orange chili sauce has the potential to be a natural fixator because it contains citric acid. This research aims to analyze the effect of the concentration of chili pepper fixator (Citrus microcarpa) on the color fastness of cotton fabric using natural dyes from Dayak onion bulbs (Eleutherine palmifolia (L.) Merr). The research method used was an experiment using a colorimeter application whose results were in the form of ΔE values. The test was carried out on the color of the fabric that had been dyed and fixed and then the average value (ΔE) was measured before and after washing the soap. The research results showed that the average value (ΔE) of the smallest to largest fixator was a concentration of 20%, 100%, 0%, 40%, 60% and 80%. Based on the results of the Kruskal Wallis test followed by the Bonferroni test, a significant value of 0.024 (p>0.05) was obtained at a concentration of 20%. This shows that the chili lime fixator has a significant influence on the fastness of the fabric.

Published: January 2025

The use of synthetic dyes in the textile industry has a negative impact on the environment. One solution that can overcome this impact is to switch to using natural dyes. However, natural dyes tend to produce less stable colors and fade easily. For this reason, a fixator is needed that can strengthen and maintain the natural dye in the fabric. Rambai fruit was chosen as a fixator because of the content of ascorbic acid which has the potential to be a natural fixator. This study aims to analyze the effect of the concentration of rambai fruit vinegar fixator on the dyeing of cotton fabrics with Dayak onion extract on color fastness. This research method is included in experimental research using the ΔE value as analysis data. Based on the results of the ΔE value, the concentration of 80% has the best level of color fastness. The results of the anova one-way test on the variation of the rambai fruit vinegar fixator obtained a significant result (p<0.05). This shows that there is an effect between the use of rambai fruit vinegar fixator concentration and color fading resistance using Dayak onion bulb extract. At a concentration of 80%, rambai fruit vinegar fixator is the most optimal concentration as a cotton fabric fixator with dye of Dayak onion bulb extract (Eleutherine palmifolia (L.) Merr) with a ΔE value of 3.47. Thus, rambai fruit vinegar with a high concentration can be an alternative fixator in the textile industry. This research contributes to the development of more environmentally friendly natural fixator materials in the textile industry that replace more harmful chemical fixators.

It is noted that at least 2.2 billion people suffer from visual impairment worldwide. There is a worldwide trend of increasing the annual increase in ophthalmic patients in all population groups. This article discusses the problem of deterioration of ophthalmological health of students. During their studies at the university, the health of students deteriorates, there is an increase in chronic pathology, including ophthalmology. By the end of the institute, about 50-70% of students have visual impairments. The article considers the issues of the influence of students' learning conditions outside educational institutions on the deterioration of ophthalmological health. The students of the medical university were studied by means of a questionnaire. It is established that more than 90% of students prepare for classes in comfortable home conditions. About a third of the students are engaged in self-training in the prone position. And among them, there is a higher percentage of people with progressive posture disorders and progressive visual impairment compared to those who practice sitting. The high intensity of the educational process with prolonged, more than 4 hours a day, use of electronic devices, including mobile phones, smartphones, tablets, desktop computers, is accompanied by a large visual load and leads to visual fatigue in 72.8% of the studied. The obtained data state the need to take them into account for the development of a set of preventive measures aimed at continuing the formation of healthy lifestyle attitudes among students, attracting internists, orthopedists, ophthalmologists, hygienists, since prevention and compliance with hygienic standards play a crucial role in maintaining the health of every person.

. It is known that one of the main factors of the modern problem of cocoon-winding production is: the low level of cocoon cultivation in the agricultural sector, the imperfection of thermophysical and technological processes in the operation of existing equipment for the primary processing of cocoons, due to the lack of scientifically based work in this direction. With modern factory cocoon reeling, it is almost impossible to unwind all the cocoons harvested during the season in a short period of time. To provide cocoon reeling factories with raw materials for year-round operation, it is necessary to protect the cocoon shells from damage by butterflies, i.e., it is necessary to preserve the cocoons, preventing the pupae from developing into butterflies. To do this, you need to either store the cocoons in conditions that exclude (or inhibit) the process of turning pupae into butterflies, or kill the pupae in the cocoons. The most common is the second method, called pickling cocoons.

Figurative Signs of the Concept "Friendship" in English and Kyrgyz Language Views of the World
Authors: Davletalieva N.
Published: January 2025

The concept of "friendship" is an important phenomenon that reflects the cultural, social, and psychological aspects of interaction between people. Language plays a key role in expressing and perceiving friendship, while metaphors help to uncover the peculiarities of how this phenomenon is perceived in different cultures. This article examines the figurative characteristics of the concept of "friendship" in English and Kyrgyz languages. Research shows that in English, friendship is often associated with images such as "guiding star," "tree," "bridge," and "sun," which symbolize support, stability, and mutual understanding. For example, the metaphor "guiding star" highlights the importance of a friend who lights the way in difficult times, while the "tree" symbolizes the strength and longevity of the relationship. These images reflect important aspects of friendship, such as support, trust, and closeness. In the Kyrgyz language, friendship is perceived through images of reliability and selflessness, such as "joldosh" (companion), which emphasizes mutual support and assistance. In Kyrgyz culture, not only emotional but also physical help in difficult times is important, reflected in metaphors like "a friend like a brother" and "blood." Additionally, in the Kyrgyz language, friendship is associated with sincerity, respect, and the durability of relationships, expressed in phrases such as "I am ready to give my soul for a friend" ("dos үчүн жанымды да бергенге даярмын"). Thus, the concept of friendship in English and Kyrgyz highlights the importance of supportive and mutually helpful relationships, but reflects different cultural and social nuances.
