Abstract

The research is purposed to describe the problem-solving ability of the Senior High School XI grader students in Palu city. The measurement of the problem-solving ability could be determined by solving the exercises of Hydrocarbon and Thermochemistry topics using the Polya’s sequences; consisting of understanding the problem, devising, doing the plan, and evaluating. The ability of students’ problem solving is classified well in every sequence in case of the number of high category students is 60%. The samples are 240 of 507 XI grade students learning chemistry in SMAN 3 and SMA Madani Terpadu in Palu City. The data of problem-solving is determined by providing a test in the form of a validated assay. The result shows the average of XI graders in Palu City only capable of solving the problem without understanding, devising, and evaluating while solving hydrocarbon topics. The ability is not even possessed by students in Thermochemistry. It implies that senior high school students in Palu could not represent the problem in the form of figure, symbol, statement, and mathematics statement or have not been able to devise the problem solving and correlate the obtained result with the related theory or concept. Therefore, the students should be trained to solve the problem in learning by application the problem-solving sequences.

Abstract

This Community Service Program (PKM) aims to enhance the creativity of children and adolescents at Sanggar Seni Kololio, Sigi Regency, through training in creative diversification based on the Kaili ethnic culture. This program was initiated due to the low literacy rate and environmental awareness among children in Kaleke Village. The project has two main focuses: improving literacy and increasing environmental awareness. Literacy improvement is achieved by establishing a Reading Corner (Pondok Baca) filled with various activities such as free reading, storytelling, book discussions, and reading journals. Meanwhile, environmental awareness is increased through activities like creating herbariums and insectariums, making trash cans from plastic waste, and crafting handicrafts from recycled materials. The program utilizes a participatory approach, actively involving the community in every stage of the process. The implemented methods include education, training, empowerment, demonstration, and appreciation. The expected output of this activity is the documentation of community service activities in the form of a scientific article. The target achievements of this project include increasing children's interest in reading, environmental awareness, and skills, as well as the availability of an adequate Reading Corner. The results of this PKM activity indicate that the program has run well and achieved its objectives. Indicators of the program's success include increased creativity of children and adolescents, diversification of artistic creations, strengthening the capacity of Sanggar Seni, and community empowerment.
