Abstract

Critical thinking is increasingly important with the existence of Artificial Intelligence (AI) especially for college students. AI is not yet fully accurate in solving mathematical problems, so critical thinking helps students analyze and evaluate its answers. This study aims to enhance students’ critical thinking using PBL (Problem-Based Learning) with ChatGPT and GeoGebra. This quasi-experimental study with the pretest-post-test non-equivalent group design involved 47 subjects, 24 in the experimental group and 23 in the control group. The average pre-test and post-test of experimental (47.96 and 62.13) and control (55.48 and 54.26) groups were significantly different. The ANCOVA results showed that PBL with ChatGPT and GeoGebra significantly enhanced students’ critical thinking. Tukey’s test result showed that the difference between the experimental and control group was 14.88 which indicated that students’ critical thinking in the experimental group was higher than the control group. Furthermore, the treatment did not affect identify indicator, but had a positive effect on justify, inference, clarify, and strategy decision indicators. This demonstrates that PBL assisted by ChatGPT and GeoGebra enhances students’ critical thinking. The research has the potential to support lecturers in enhancing students’ critical thinking and improving innovative learning models where AI can be used in education with proper guidance and implications.Berpikir kritis semakin penting dengan adanya kecerdasan buatan (AI) khususnya bagi mahasiswa. AI belum sepenuhnya akurat dalam menyelesaikan masalah matematika, sehingga berpikir kritis membantu mahasiswa menganalisis dan mengevaluasi jawabannya. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan PBL berbantuan ChatGPT dan GeoGebra dalam meningkatkan kemampuan berpikir kritis mahasiswa. Populasi penelitian ini adalah seluruh mahasiswa Program Studi Pendidikan Matematika pada semester 4. Sampel penelitian dipilih menggunakan teknik cluster sampling dengan penentuan kelas eksperimen dan kelas kontrol secara acak. Penelitian kuasi-eksperimen ini dengan desain pretest-post-test non-equivalent group melibatkan 47 subjek, 24 pada kelompok eksperimen dan 23 pada kelompok kontrol. Rata-rata pre-test dan post-test kelompok eksperimen (47,96 dan 62,13) dan kontrol (55,48 dan 54,26) berbeda secara signifikan. Hasil ANCOVA menunjukkan bahwa PBL dengan ChatGPT dan GeoGebra secara signifikan meningkatkan berpikir kritis mahasiswa. Hasil uji Tukey menunjukkan perbedaan antara kelompok eksperimen dan kontrol sebesar 14,88 yang mengindikasikan bahwa berpikir kritis mahasiswa pada kelompok eksperimen lebih tinggi dibandingkan kelompok kontrol. Selain itu, perlakuan tidak berpengaruh pada indikator identify, tetapi memberikan pengaruh positif pada indikator justify, inference, clarify, dan strategy decision. Hal ini menunjukkan bahwa PBL yang dibantu oleh ChatGPT dan GeoGebra meningkatkan berpikir kritis mahasiswa. Penelitian ini berpotensi mendukung dosen dalam meningkatkan berpikir kritis mahasiswa dan memperbaiki model pembelajaran inovatif di mana AI dapat digunakan dalam pendidikan dengan bimbingan dan implikasi yang tepat.

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas ChatGPT sebagai alat bantu mahasiswa untuk berpikir kritis dan mendeskripsikan berpikir kritis mahasiswa dalam menyelesaikan masalah aljabar dengan bantuan ChatGPT. Penelitian ini merupakan penelitian mix method dengan explanatory sequential design yaitu data dianalis analisis secara kuantitatif terlebih dahulu dan dilanjutkan dengan secara kualitatif deskriptif. Hasil penelitian ini menunjukkan rata-rata nilai berpikir kritis kelas ChatGPT (56,67) lebih besar daripada kelas kontrol (41,33). Hasil analisis uji-t menunjukkan bahwa t-hitung (2,58) > t-tabel (2,03) dan nilai p-value 0,007 yang mana lebih kecil dari 0,05. Sehingga dapat disimpulkan bahwa hipotesis awal (H0)ditolak yang artinya ChatGPT efektif untuk mendorong mahasiswa kemampuan berpikir kritis. Lebih lanjut mahasiswa yang berpikir kritisnya tergolong tinggi akan mempertanyakan kredibelitas informasi dari ChatGPT maupun masalah, membuat kesimpulan yang tepat dari informasi yang diperoleh, dan menyelesaikan masalah dengan strategi yang tepat. Sedangkan mahasiswa yang berpikir kritisnya tergolong rendah menerima informasi dari ChatGPT maupun masalah tanpa mempertanyakan kredibilitasnya, dan hanya menyalin apa yang dikerjakan oleh ChatGPT tanpa memperhatikan kebenarannya.Kata kunci: Berpikir kritis, ChatGPT, Masalah aljabar, Mahasiswa Abstract: This research aims to determine the effectiveness of ChatGPT as a tool for assisting per-service teachers in critical thinking and describe the critical thinking of students in solving algebra problems with the help of ChatGPT. This study uses a mixed-methods approach with an explanatory sequential design, where quantitative analysis is conducted first, followed by qualitative descriptive analysis. The results of this research show that the average critical thinking score for the ChatGPT class (56.67) is higher than the control class (41.33). The t-test analysis indicates that the t-value (2.58) > t-table (2.03) with a p-value of 0.007, which is smaller than 0.05. Therefore, it can be concluded that the null hypothesis (H0) is rejected, meaning that ChatGPT is effective in enhancing pre-service teachers’ critical thinking abilities. Furthermore, pre-service teachers with high levels of critical thinking tend to evaluate the credibility of information from both ChatGPT and problems, make the correct conclusions from acquired information, and solve problems using appropriate strategies. On the other hand, pre-service teachers with low levels of critical thinking tend to accept information from ChatGPT and problems without questioning their credibility, merely copying what is generated by ChatGPT without paying attention to its accuracy.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the national economy, including in Kapuas Regency, Central Kalimantan, which is dominated by the culinary sector. However, most MSME owners have not yet obtained halal certification due to limited understanding, lack of access to information, and the perception that the certification process is complicated. This community service program aimed to improve MSME owners’ awareness, knowledge, and technical capacity in obtaining halal certification through the self-declare scheme. The service method employed a participatory and mentoring-based approach, implemented through structured stages consisting of preparation, implementation, and evaluation. The preparation stage involved coordination with local stakeholders, identification of MSME needs, and participant registration. The implementation stage consisted of material delivery using lectures and discussions to enhance awareness of the importance of halal certification, followed by hands-on technical assistance in using the official online halal certification system. Participants were also guided through a simple internal audit of production processes to ensure compliance with halal standards. The evaluation stage was conducted using questionnaires and direct observation to measure participants’ satisfaction, understanding, and ability to independently complete the halal certification registration process. A total of 37 culinary MSME participants successfully completed the halal certification registration through the self-declare scheme. Evaluation results indicated that the program was highly beneficial, with an average participant satisfaction rate exceeding 80%. Furthermore, the program increased MSME owners’ awareness of halal certification as a guarantee of product quality and a strategic tool for enhancing business competitiveness. Overall, this community service program successfully strengthened MSME capacity in utilizing digital-based halal certification systems and supported the development of a more competitive halal MSME ecosystem in Kapuas Regency.
