Teachers in learning activities should carry out practicum activities to facilitate students' learning, so there are no misconceptions. The facts in the field say that many teachers still do not do practicum because of the availability of tools and materials at the school, so virtual simulations are needed as a medium in practicum activities. The development model used in this study consists of three stages, namely the definition stage, the design stage, and the development stage. The results showed that the virtual simulation was feasible to use in the learning process. The validation analysis on the developed virtual simulation with very achievable criteria. In the student's opinion, the virtual simulation feasibility with very feasible criteria. Teachers in learning to remediate misconceptions can use the virtual simulation that has been developed.

This study aims to encourage the critical thinking skills (CTS) of students through the Wave Energy Learning Project (WELP) program, which is applied with an early-assisted project-based learning model (EA-PjBL) in Environmental Physics lectures. The research focuses on the topic of the environment as a renewable energy source, especially ocean wave energy. In the WELP program, there is a prototype of ocean wave energy that has been developed as a teaching aid and an initial project model that pre-service physics teachers will develop. The data collection instrument used was a description test of the concept of ocean wave energy based on CTS, performance and product assessments, peer performance assessments, lecture observation sheets, and pre-service physics teachers’ perception sheets. The research subjects were 31 pre-service physics teachers in the sixth semester of the Physics Education study program at one of the academic staff education institutions in West Nusa Tenggara. The research data were analyzed using descriptive statistics, N-gain test, t-test, and effect size analysis. The data analysis results show a strong influence on the use of the WELP program through the EA-PjBL learning model on improving the CTS of pre-service physics teachers. The CTS of pre-service teachers has increased by category after attending lectures using the WELP program. This research implies that the WELP program developed can be a model for developing lecture programs on other renewable energy materials that enhance the development of higher-order thinking skills. The project in this research triggers the younger generation to contribute to overcoming the global electrical energy crisis.

In this article, the focus of the research is the employees of Koperasi Tani “Jasa Tirta“ Sendang, who expects all employees to be able to work optimally to achieve the desired results. As for the purpose; 1) determine the effect of Islamic work motivation on employee performance; 2) determine the effect of the work environment on employee performance; 3) the influence of Islamic work motivation on employee performance through work discipline as an intervening variable; 4) the influence of the work environment on employee performance through work discipline as an intervening variable Koperasi Tani “Jasa Tirta“ Sendang. This study uses a quantitative approach. The population in this study were Koperasi Tani “Jasa Tirta“ Sendang, with a sample of 30 people. The sampling technique used is purposive sampling. Data collection techniques using online questionnaires via google form. The analysis tool uses SPSS 16.00. The results of the study show that: (1) Islamic work motivation has a significant direct effect on employee performance; (2) the work environment directly does not have a significant effect on employee performance; (3) Islamic work motivation indirectly has a significant effect on employee performance through work discipline (4) the work environment does not indirectly have a significant effect on employee performance through work discipline. Koperasi Tani “Jasa Tirta“ Sendang. The limitation of this research is that it only examines the effect of work motivation, work environment, and work discipline, while other variables that affect employee performance are expected to be investigated by further researchers
