Abstract

This research aims to determine the profile of science practicum lectures, logical thinking abilities, and systems thinking skills of prospective science teacher students in Sorong Regency. This research is a case study with pre-research, implementation, and final/post-research stages. The subjects of this research were students who were or had contracted for science practicum course. The instruments used are analysis lists, logical thinking test instruments, systems thinking scales, and systems thinking skills tests. Interviews were also conducted to support the data that had been obtained. The research results show that (1) the practicum activities that have been running so far have only trained skills in collecting, processing, and analyzing scientific research data. (2) The contents of the practicum instructions do not train students' thinking skills, such as critical thinking, systems, or problem-solving. (3) Students' logical thinking abilities are relatively evenly distributed at proportional, correlational, and combinatorial reasoning levels; however, the majority of students have reasoning in the transitional category, and there is quite a high level of concrete reasoning. (4) Students' systems thinking skills are relatively low, especially forest thinking skills. Different and innovative practicum lecture approaches need to be developed to improve logical thinking and systems thinking skills for prospective science teacher students in Sorong Regency. Low levels of logical thinking and systems thinking skills will have implications for achieving skills at the next level, such as the skills needed today, namely 21st-century skills.

Abstract

The issue of clean water availability in coastal areas remains a serious challenge, particularly due to increasing seawater intrusion, which causes groundwater to become brackish and unfit for consumption. This condition is also experienced by the community in Warmon Kokoda Village, Sorong Regency, who have long depended on well water sources with high salinity levels. This community service activity aimed to introduce and train residents in the use of single-roof solar desalination technology with a solar-powered cooling fan as an energy-efficient and environmentally friendly solution for brackish water purification. The approach used was Participatory Action Research (PAR), in which the community was actively involved in socialization, learning, and hands-on practice in the manufacture and operation of the device. The results of this activity showed an increase in community knowledge about the working principles and benefits of solar desalination technology, as evidenced by the community's ability to conduct trials on the device. Technical tests showed that the device was able to reduce the salinity of brackish water from 5% to 0%, producing water suitable for consumption according to WHO standards, with good thermal efficiency for the household category. This activity had a significant impact in providing access to safe and potable water for the local community, as well as increasing independence in water resource management.
