“…Instrument development was conducted through three stages, namely (1) item preparation, (2) construct validation using the Exploratory Factor Analysis (EFA) method and Confirmatory Factor Analysis (CFA), and (3) item validation using the RASCH model (Sukri et al ., 2022). The research sample was taken randomly (Endo et al, 2016). This study used 681 students from 25 universities in Indonesia.…”

This study aims to compile and validate Pancasila character instruments using three methods: Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and the RASCH model. This research is a survey involving 681 students from universities throughout Indonesia. The study consisted of three stages, namely (1) item preparation, (2) construct validation through EFA and CFA, and (3) item validation using the RASCH model. The preparation of Pancasila character instrument items was carried out through a literature review and 44 statement items covering six aspects of Pancasila character. After EFA was conducted, 44 items were eliminated into 33 items which were divided into five constructs or factors, namely factor 1 = Ethics, Nationalism, Independent and Critical, factor 2 = Self Efficacy, factor 3 = Empathy, factor 4 = Creativity, and Global Knowledge, and factor 5 = Discipline. This result is reinforced by the CFA, which shows that the factors formed are in accordance with the model and have items that can describe the character of Pancasila (loading factor ≥0.3). Further analysis using RASCH shows that the instrument developed has good validity and reliability and can be used to measure students' Pancasila character.

“…If the area of the density function is large in the negative domain of the limit state equation, it is very important to calibrate the model correctly to obtain good reliability. The inverse of the ω ratio can be used to evaluate the variability of the predicted equations (Bernaards and Sijtsma, 2005; Endo et al, 2016; Takeda and Matsumoto, 1993).…”

In cold-formed steel members under tension and connected with bolts, the resistance capacity of the net section should be calculated, taking into account the shear lag phenomenon. This is done through the net section reduction coefficient, Ct. Different Standards show different equations for Ct. In this work, experimental laboratory data of cold-formed steel angles from the authors are used for the evaluation of the accuracy of the predictions of the net section capacity of members under tension. Such predictions are given by the equations of AISI, Eurocode-3, Brazilian standard NBR 14762, and also by a predictive equation previously proposed by the authors. The paper shows how each equation predicts the tension member resistance capacity in front of the experimental data. Most of the equations in the design standards have good predictions when more sections of the steel angles are connected. The results show that the AISI standard presented the best resistance capacity prediction and lower standard deviations of the output response upon uncertainty.

Understanding the concept and attitude of environmental care attitudes is necessary for preserving local excellence. This study aims to determine the effect of implementing local excellence-based comic media on the conceptual understanding and environmental care attitude of Islamic boarding school students of a different gender. This research is quasi-experimental, using a one-group pre-test and post-test design. The research was conducted in three Islamic boarding schools, i.e. MTS MT Mamben, SMP IT Putra Ar-Risalah Paok Lombok, and SMP IT Putri Ar-Risalah Paok Lombok, involving 38 female and 30 male students. The research instrument used a test to determine students' conceptual understanding of local excellence and a questionnaire to assess students' environmental care attitudes. Data were analyzed using N-gain, one-way ANOVA, and continued with post hoc tests to determine the effect of implementing comic media in each experimental group. A DIF analysis was carried out on questionnaire items using RASCH to determine students' environmental care attitudes of different genders. The results showed that (a) the implementation of comic media based on local excellence at Islamic boarding schools could increase students' understanding of local excellence (N-gain = 0.44 to 0.60) and increase students' environmental care attitude (N-gain = 0.33 to 0.58), (b) there are differences in concept understanding and environmental care attitude in the experimental group (Sig <.05). These results indicate that there is a relationship between conceptual understanding and students' environmental care attitudes. The higher the conceptual understanding, the higher the students' environmental care attitude, and vice versa, and (c) female students tend to have a better environmental care attitude than male students. However, on the other hand, male students can think logically and rationally, so they tend to care about the causes of damage to local excellence, especially coral reef ecosystems
