“…By conducting experiments in the laboratory, students are able to observe and analyze chemical reactions and phenomena, allowing them to apply theoretical knowledge to real-world scenarios (Chen et al, 2019) (Ramírez et al, 2020). One of the key benefits of the laboratory is that it provides students with the opportunity to engage in active learning (Trisusilosakti & Aisyah, 2020). Instead of simply memorizing facts and formulas, students can actively participate in the scientific process by designing experiments, making observations, and drawing conclusions (Laelasari et al, 2019) (Leopold & Smith, 2020).…”

In the Radiochemistry course so far there have been no experimental activities because there are no laboratory facilities. However, with the use of technology, students can now easily access a wealth of educational resources online. This research aims to determine the effect of using the PhET Simulations as a virtual laboratory on students' problem solving skills. This research used mixed methods that combines quantitative and qualitative research. A quasi-experiment was carried out using a one group pretest-posttest design then continued with in-depth interviews. The instruments used in this research consisted of written tests to collect data on problem solving skills, questionnaires to collect student response, and interview guides to collect data on the problem solving process. Data in the form of problem solving skills were analyzed statistically using the SPSS 22.0 program while data obtained through questionnaires and interviews were analyzed descriptively. The results of the hypothesis test using Wilcoxon signed rank test show a significant value of 0.001, which means that PhET simulations as a virtual laboratory improve students’ problem solving skills. Students are divided into high-medium-low groups based on problem solving ability and the majority of students are in the medium-ability group. Students responded positively to PhET Simulations as a virtual laboratory. In addition, interview transcripts provide an overview of how students think when solving chemistry problems.

“…The material used to carry out the mini project is related to the theory in the course, by taking different materials from the material used during the practicum (Nurmilawati & Rahmawati, 2018). In the first stage, namely the introduction of practicum activities in the form of a pre-test, then the teacher gives an explanation about the Mini-Project laboratory that will be carried out and the research schedule (Trisusilosakti & Aisyah, 2020). The second activity forms groups.…”

This study aims to describe the supporting facilities for the Natural Science Mini Project Practicum (PIMPA) model of learning from the availability of tools and chemicals as well as books or literature available in SMP throughout Mataram City. This research was conducted in three schools spread outside the urban areas of Mataram City, especially those located close to the tourism area of Mataram City, namely: SMPN 11 Mataram, SMPN 17 Mataram, and SMPN 21 Mataram. The research subjects were laboratories and libraries, and the research objects were laboratory support facilities. The form of activity carried out is the recording of documents (inventory) of laboratory equipment and their use in science practicum activities. The data from this study were analyzed descriptively qualitatively. The results of this study indicate that the laboratory carrying capacity in the PIMPA model is the availability of laboratory equipment for science practicum activities at SMPN 11 Mataram is 77.27% (adequate); SMPN 17 Mataram available 77.27% (adequate); and SMPN 21 Mataram available 72.72% (adequate).
