Abstract

The development of the silk textile industry in Indonesia is supported by several provinces including South Sulawesi. South Sulawesi has several centers for the development of mulberry and silkworm cultivation which are the basic ingredients for making silk cloth. Silk cloth is one of the processed products from silk thread which is produced from cocoons produced by silkworm cultivation and woven into silk cloth. Traditional woven fabrics produced in regions in Indonesia, including South Sulawesi, are not only made for clothing purposes. The purpose of this study is to determine the price of silk cloth by applying the Mamdani fuzzy method to the MATLAB software, so that silk cloth businesses can set prices according to the quality of the goods. Fuzzy logic is considered capable of mapping an input into an output without ignoring the existing factors. Based on this, fuzzy logic will produce a model of a system capable of estimating selling prices.

Abstract

This study examines the influence of digital literacy and technostress on elementary school teachers’ performance with instructional innovation as a mediating variable within the Job Demands–Resources (JD-R) framework. The research employed a quantitative explanatory design using Partial Least Squares Structural Equation Modeling (PLS-SEM). Data were collected from elementary school teachers in West Kalimantan Province through an online questionnaire. The results indicate that digital literacy has a significant positive effect on instructional innovation and teachers’ performance. Instructional innovation also significantly improves teachers’ performance. Meanwhile, technostress does not have a direct effect on teachers’ performance but does influence it indirectly through instructional innovation. These findings suggest that digital literacy functions as an important job resource that enhances innovative teaching practices. In contrast, technostress can act as a challenge that stimulates adaptive innovation in digital learning environments. The model demonstrates strong explanatory power with an R² value of 0.706 for teachers’ performance. The study contributes to the development of JD-R theory in digital education by identifying instructional innovation as an adaptive mechanism that transforms job demands and job resources into improved teacher performance.
