“…Meanwhile, the results of the construct validity analysis using EFA, when viewed from the KMO value = 0.634, the Bartlett's Test value = 0.000 <0.05 and the MSA value> 0.5 so that the instrument items are declared feasible (Harmurni, 2019;Yamin, 2021). This finding is supported by research conducted by Junpho et al (2022) and Sovey et al (2022), which states that the computational thinking test instrument has instrument construct validity that is feasible to use in research.…”

“…Measurement of the instrument construct with EFA states that the instrument item is declared feasible or not if the Kaiser-Meyer-Olkin Measure of Sampling Adequacy test results> 0.50 and the Barlett's Test of Sphericity test results Sig. value <0.05(Harmurni, 2019;Yamin, 2021).ReliabilityThe estimation of instrument reliability in this study used the Cronbach Alpha technique. According toSubando (2022) andIstiyono (2020) the formula and interpretation of the reliability coefficient are shown in Table2.…”

This study aims to analyze the validity and reliability of the diagnostic test instrument used to measure computational thinking skills based on local wisdom. This method of research is instrument development research. The subjects of this research were students of computer science and information technology undergraduate programs at Bumigora University, totaling 108 students using a random sampling technique. Data collection techniques using tests. The data analysis technique of instrument content validity was determined based on Aiken's V formula, instrument construct validity using EFA, and instrument reliability using Cronbach Alpha. Based on the results of this research, the content validity of the instrument has a high validity index, the construct validity of the instrument items is declared feasible, and the reliability of the instrument has a high-reliability coefficient. So, this instrument is declared valid, reliable, and suitable for use to measure local wisdom-based computational thinking diagnostic tests.

“…The value of the tensile strength is 0,963 and has a negative value. The value of 0,75-0,99 has a very strong correlation and the negative value means if the X-axis goes up, the Y-axis goes down [21]. The addition of glycerol greatly effects to decrease tensile strength.…”

“…1 the correlation of the addition of glycerol concentration to the edible film thickness has a value of 0,474. According to Sarwono [21], the value of 0,25-0,49 has a weak correlation and the positive value means that 2 variables have a linear correlation, or if the X-axis goes up, the Y-axis goes up too. This means that in this study the correlation is weak.…”

Making edible films from potato starch by adding glycerol from used cooking oil with various concentrations of 10, 20 and 30% (v/w starch). This study aims to determine the physical properties of edible films made using these materials and the effect of adding variations in glycerol concentration on the physical properties of the resulting edible films. The physical property tests carried out included thickness, tensile strength, elongation and WVTR (Water Vapor Transmission Rate) tests as well as to see the effect using the pearson correlation test on SPSS version 25. The physical properties of edible film made from potato starch raw materials with the addition of variations in glycerol concentration produced successive thicknesses respectively 0.0670; 0.0674 and 0.0818 mm. Tensile strength respectively 24.237; 14.929 and 3.417 N/m2. Consecutive elongation 2.4064; 5.6768 and 20.096 %. As well as WVTR 5.05556 respectively; 6.38426 and 8.36574. The addition of variations in glycerol concentration to the physical properties of the edible film showed that the addition of glycerol did not significantly affect the thickness, but greatly affected the tensile strength, elongation and WVTR of the resulting edible film.
