Abstract

The gap between theory and laboratory practice often presents a major obstacle in vocational education, particularly within the industrial chemistry competency. This community service initiative was established to bridge this disparity by strengthening the Science Process Skills (SPS) of students at SMK Negeri 8 Jayapura through technical training in Titrimetric and Gravimetric analysis. The implementation method adopted an experiential learning approach, encompassing conceptual presentations, interactive discussions, and direct experimentation. This intervention was designed to cultivate skills in observation, precision measurement, and data interpretation. Evaluation results demonstrated a significant surge in cognitive competence, marked by a 32.3% increase in average test scores. In the psychomotor domain, the majority of students were able to demonstrate analysis techniques with high precision (error <3%). These findings indicate that intensive supervision with an adequate instructor-to-student ratio is effective in building standardized laboratory competencies.

Abstract

Early childhood science education plays a vital role in shaping children's cognitive structures, literacy, and numeracy. However, the general perception of chemistry as a complex discipline often acts as a barrier to its introduction at the elementary level. This community service activity aims to destigmatize this perception by introducing chemical science using simple, joyful learning experiment methods. The program was conducted at the Pentecostal Children's Service (PELNAP) of GPdI PISGA, Abepura, targeting the 5-12 age group. The intervention was carried out through two main experimental modules: volcanic eruption simulation and balloon inflation via chemical gas reaction. The implementation methods included demonstration stages, guided independent experiments, and participatory observation. The results showed a significant increase in children's attention and intrinsic interest in scientific phenomena. Through an inquiry-based approach, children were able to understand the basic concepts of acid-base reactions producing carbon dioxide (CO2) gas in a concrete manner. It is concluded that the integration of experiment methods based on natural materials is effective in stimulating scientific curiosity and children's cognitive development, while offering an interactive science learning alternative outside the formal school environment.

Abstract

Literasi membaca merupakan kompetensi dasar yang penting dalam mendukung perkembangan akademik murid sekolah dasar, namun kemampuan membaca pemahaman, khususnya pada tingkat kalimat sederhana, masih menjadi permasalahan di berbagai satuan pendidikan. Penelitian ini bertujuan menganalisis peningkatan gerakan literasi membaca pemahaman melalui buku cerita dalam meningkatkan keterampilan membaca kalimat sederhana pada murid kelas III SD Inpres Anduam. Penelitian ini merupakan penelitian kuantitatif dengan desain pra-eksperimen tipe one-group pretest–posttest. Subjek penelitian terdiri atas 9 murid kelas III yang dipilih menggunakan teknik total sampling. Data dikumpulkan melalui tes keterampilan membaca kalimat sederhana sebelum dan sesudah intervensi, kemudian dianalisis menggunakan statistik deskriptif dan uji paired samples t-test. Hasil penelitian menunjukkan adanya peningkatan signifikan kemampuan membaca murid, ditandai dengan kenaikan skor rata-rata dari 58,22 pada pretest menjadi 78,56 pada posttest (p < 0,05). Temuan ini menunjukkan bahwa gerakan literasi membaca pemahaman berbasis buku cerita efektif dalam membantu murid memahami struktur dan makna kalimat sederhana. Penelitian ini merekomendasikan penerapan gerakan literasi membaca pemahaman secara berkelanjutan sebagai strategi pembelajaran membaca di sekolah dasar.
