Abstract

Green technology for eco-friendly dyes in textile industries has been required in recent decades. An innovation was established by producing textile dyes from natural sources. This research aims to identify fine particle powder's characteristics and analyze the color changes applied to the textile. The mechanical thermal was utilized to produce natural dyes. Three main stages were conducted to obtain dye powder: mordant, coloring, and fixation. The dye powder was examined for water content, phytochemical tests, FTIR, SEM-EDX, and color using the Android-based Color Analyzer and Color Grab applications. The results show that the water content of 7.21% meets the SNI 01-3709-1995 standard. So, the powder can be stored for a long time because it does not quickly spoil. In addition, the phytochemical test resulted in alkaloids, flavonoids, and tannins. This revealed that teak leaf powder can be a suitable textile dye. After that, SEM-EDX examination illustrated that the powder had a round, flat, elongated morphology, a sharp edge texture, and an irregular position. Meanwhile, the EDX signified that the recognized chemical elements did not damage the environment, and the powder diameter ranges from 0.5-8.5 μm. The powder size complied with the fine particle powder category. To analyze the color from the dye powder application, there were color changes during each dyeing process. During all stages, from making the powder to applying the powder to the fabric, environmentally friendly technology was utilized. Therefore, this research can promote new opportunities for innovation and development of highly competitive products towards a more environmentally friendly and sustainable textile industry.

Abstract

Word error correction is challenging due to the variety of errors. This research proposes a combination of two similarity algorithms to improve accuracy. The objective is to evaluate how each algorithm responds to different types of spelling errors and to assess the effectiveness of their combined performance. Jaro-Winkler determines initial similarity by assigning more weight to word prefixes, effectively addressing errors due to transposition and character omission. This algorithm excels in scenarios where the beginning of the word is critical to identifying the correct candidate. In contrast, Jaccard similarity filters candidates based on character set similarity, which helps assess the overall composition similarity of the word but does not consider character order. The test results show that Jaro-Winkler is more dominant in providing relevant correction candidates, with higher accuracy in the 1-best (68.94%) and 5-best (90.78%) scenarios compared to Jaccard (55.25% and 78.42%). This performance difference suggests that Jaro-Winkler is more suitable for the initial screening of candidates. The combination of the two algorithms proved to be more effective in handling different types of word errors than when used separately, resulting in a more robust overall correction mechanism.

Abstract

Lombok has become one of the leading tourist destinations, especially with the development of the Mandalika Special Economic Zone. One of the cultural products that has the potential to be offered to tourists is Lombok traditional weaving. The study aims to analyze the effect of the pH of the dye solution on the characteristics of the dyed fabric. The research method uses a mechanical thermal method to obtain anthocyanin powder extraction, standard staining methods namely mordan, staining, and fixation, as well as characterization using tensilons, Color Analyzer software, Hooloovoo, and Encycolorpedi website. The extraction of anthocyanin compounds from teak leaves (Tectona grandis) was successfully carried out by mechanical thermal method. Color analysis and identified color changes are significantly affected by differences in solution pH. The higher the pH used, the darker the color will be produced and the higher the level of color fading in the fabric. The smallest  E value is at pH 6 =5.364 and the largest  E value is at pH 14 = 17.145. However, an increase in pH tends to increase the tensile strength of the fabric. However, the optimum tensile strength condition was obtained in a solution of pH 12, which was 17.414 MPa, while at pH 13 and pH 14, the tensile strength of the fabric decreased to 16.071 MPa. Based on the analysis of the influence of pH of dye solution on fabric tensile strength, it was identified that a 6th-order polynomial model (determination coefficient R2 = 0.9479) was identified as accurate enough to model the influence of pH on fabric tensile strength. Therefore, this finding has potential in the textile industry, especially in increasing the economic value of Lombok weaving.

Abstract

The inefficiency in the futsal field rental process in Mataram City, which still relies on manual methods such as booking by telephone or booking directly, results in delays in confirmation and potential recording errors. This research aims to develop a web-based Futsal Field Rental Management Information System to streamline the booking and payment process. The proposed system allows tenants to make reservations and payments online while assisting field owners in managing rental data and creating financial reports automatically, thereby increasing efficiency and accuracy. The system was developed using the prototyping method, which allows the creation and refinement of the system in stages through early versions (prototypes) that are evaluated by users, so that feedback can be integrated directly in each development cycle. System testing conducted using the Blackbox method shows that the developed system can function properly, simplify the ordering process, reduce recording errors, and improve business operational efficiency. In addition, testing was also carried out using the Mean Opinion Score (MOS) method to evaluate user satisfaction from a subjective perspective, providing insight into the perceived usability and acceptance level of the system. In conclusion, the implementation of this system effectively answers the challenges in futsal field rental by providing a faster, transparent, and efficient solution for both tenants and managers.
