Abstract

Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh keterbatasan fasilitas laboratorium di SMA Negeri 5 Maluku Tengah yang membuat siswa jarang berinteraksi langsung dengan konsep kimia secara praktis. Padahal, minat belajar dan rasa ingin tahu ilmiah siswa akan tumbuh apabila mereka mendapatkan pengalaman belajar yang menyenangkan dan aplikatif. Oleh karena itu, tim dosen Jurusan Kimia FMIPA Universitas Pattimura melaksanakan kegiatan berupa demonstrasi eksperimen kimia sederhana yang mudah dilakukan dengan bahan-bahan sekitar. Metode kegiatan mencakup perancangan eksperimen, penyusunan booklet pembelajaran, koordinasi dengan pihak sekolah, pelaksanaan demonstrasi, dan evaluasi respon siswa. Eksperimen yang ditampilkan meliputi indikator alami asam–basa, pesan rahasia dengan tinta lemon, dan lava lamp sederhana. Hasil kegiatan menunjukkan peningkatan antusiasme siswa, keterlibatan aktif dalam mencoba eksperimen, serta munculnya keberanian untuk bertanya dan berdiskusi. Luaran kegiatan berupa booklet, berita pada laman Jurusan Kimia, serta dokumentasi video pada kanal YouTube. Dengan demikian, kegiatan ini berhasil menjadi langkah awal dalam memotivasi siswa untuk lebih mencintai pembelajaran kimia serta memperkuat kerja sama universitas dengan sekolah mitra.

Abstract

The research to determine content of metal Cu and Pb in six samples (three ore rocks and three waste rocks) in the copper mining area on Wetar Island. The results showed that the highest concentration of Cu metal for ore rocks was in the first sample (MS KK) of 106,800 ppm and the smallest Cu concentration was in the third sample (PBx 1 KK) of 411 ppm. While the largest concentration of Cu metal waste rock is the first sample (Vol 1 KK) is 1.894 ppm and the smallest Cu metal concentration is in the second sample (BA 1 KK) is 310 ppm. As for the concentration of metal Pb in the largest ore rocks is in the first sample (MS KK) of 9,890 ppm, the small metal concentration of Pb is in the third sample (PBx 1 KK) is 660 ppm and the concentration of metal Pb for waste rock is found only in the first sample (Vol 1 KK) with a concentration of 1,631 ppm. This study shows that Wetar Island contains high copper and lead deposits.
