Abstract

Pengabdian kali ini bertujuan untuk mengenalkan persepsi dasar kimia pada anak melalui eksperimen sains menarik untuk menanggulangi chemophobia. Sejumlah 30 peserta kegiatan dari MDT. Ngudi Luhur menjadi khalayak sasaran. Kegiatan disampaikan dalam dua kali pertemuan, teori dan praktik. Eksperimen kimia menarik dipilih sebagai kegiatan untuk memperkuat teori yang telah disampaikan di pertemuan sebelumnya. Eksperimen kimia menarik yang dilakukan yaitu ikan berenang, pelangi di piring, the menjadi air putih, meniup balon, lava lamp, dan pesan rahasia. Instrumen yang digunakan yaitu lembar need assessment, lembar observasi keaktifan peserta, lembar observasi unjuk kerja, kumpulan pertanyaan untuk game cerdas cermat, serta lembar angket evaluasi kegiatan. Kegiatan mencapai indikator keberhasilan ditandai dengan 81,67% peserta terlibat aktif serta 100% peserta mengikuti demonstrasi dengan baik. Keberhasilan kegiatan pengabdian menjadi salah satu kontribusi tim pengabdi dalam mengatasi kesalahan persepsi terhadap kimia yang berkembang di masyarakat yang akan lebih dirasakan manfaatnya jika diberikan sejak usia anak.

Abstract

This study conducted a systematic literature review to evaluate the recent development of transition metal-doped TiO₂ catalysts for the hydrogen evolution reaction (HER). A total of 20 selected articles were analyzed using the PRISMA approach to identify the influence of dopant type, catalyst architecture, and synthesis methods on catalytic performance. The results showed that transition metals such as Fe, Ni, Cu, and Mo significantly enhanced HER activity by introducing active sites, improving electrical conductivity, and suppressing electron–hole recombination. Among them, Fe demonstrated the most consistent performance due to its ability to modify the electronic structure of TiO₂. In addition, catalyst architectures such as heterojunctions, nanocomposites, and core–shell structures improved charge separation and increased active surface area. Synthesis methods, particularly hydrothermal techniques, played a crucial role in controlling crystallinity and dopant distribution. Overall, the enhancement of HER performance was governed by the synergistic interaction between dopant type, catalyst structure, and synthesis strategy. These findings highlighted the importance of integrated material design for advancing TiO₂-based catalysts toward sustainable hydrogen production applications.

Abstract

This study aims to analyze the role and implementation of artificial intelligence (AI)-based chatbots in chemistry learning at the high school level, particularly in strengthening understanding of abstract concepts such as atomic structure. This study uses a systematic literature review approach to 18 relevant scientific articles from 2016 to 2026 originating from reputable international journals, preprints, and empirical research results in the fields of educational technology and chemistry education. The results of the study indicate that the use of AI chatbots in high school chemistry learning can be grouped into two main categories: studies that focus on the development of AI-based learning systems and studies that emphasize the implementation of chatbots as learning aids such as virtual tutors, concept exploration agents, simulation media, and scientific writing support. In general, AI chatbots have been proven to improve student learning motivation, understanding of chemical concepts, critical thinking skills, and independent learning skills. However, several limitations were also found, such as inaccurate information, hallucination phenomena, lack of adaptation to the high school pedagogical context, and the risk of student dependence on AI technology. Specifically for atomic structure, there has been no research specifically and in-depth on the implementation of AI chatbots, leaving a significant research gap. Therefore, the development of a more contextual, targeted, and tailored AI chatbot-based chemistry learning model is needed, tailored to the characteristics of high school students.
