Abstract

Sains merupakan ilmu yang berkembang dengan cara eksperimental dan mengandung banyak pengetahuan deklaratif yang dapat dipelajari oleh peserta didik sebagai kajian teoritis prosedural yang dipelajari melalui kegiatan praktikum-praktikum IPA. Kemampuan literasi sains merupakan kemampuan seseorang menerapkan pengetahuannya untuk mengidentifikasi pertanyaan, mengkonstruksi pengetahuan baru, memberikan penjelasan secara ilmiah, mengambil kesimpulan berdasarkan bukti- bukti ilmiah, dan kemampuan mengembangkan pola pikir reflektif sehingga mampu berpartisipasi dalam mengatasi isu-isu dan gagasan-gagasan terkait sains. Salah satu upaya penguatan kemampuan literasi sains yang dapat diterapkan pada peserta didik di satuan pendidikan jenjang SMP yaitu melalui kegiatan praktikum IPA sederhana. Kegiatan praktikum menggunakan alat dan bahan sederhana yang mudah ditemukan di sekitar peserta didik merupakan usaha sadar yang dapat menarik keingintahuan peserta didik serta memperkuat pemahaman terhadap ilmu yang konkret melalui percobaan-percobaan. Kegiatan ini bertujuan untuk memberikan penguatan literasi sains melalui praktikum IPA sederhana yang berkaitan dengan konsep IPA yang dipelajari. Metode pengumpulan data yang digunakan adalah observasi. Data yang diperoleh dianalisis secara deskriptif. Berdasarkan analisis data diketahui persentase rata-rata ketercapaian kemampuan literasi sains yang diperoleh melalui praktikum IPA  sederhana yakni 76,46% dan tergolong dalam kategori sedang.

Abstract

Kegiatan ini bertujuan memperkenalkan dan mempraktikkan pemanfaatan pigmen tumbuhan lokal sebagai indikator pH dalam eksperimen kimia kepada siswa SMA Kristen Maktihan, Besikama, Timor-Nusa Tenggara Timur. Sekolah ini belum memiliki laboratorium kimia serta keterbatasan alat dan bahan praktikum, sehingga pembelajaran kimia jarang disertai eksperimen. Kegitan pembelajaran yang dilakukan berbasis eksperimen menggunakan sumber pigmen lokal yakni pigmen rimpang kunyit, daun bayam merah, bunga kencana ungu, dan umbi ubi jalar ungu sebagai salah satu sumber belajar. Keempat pigmen ini diuji dalam larutan sampel hahan kimia rumah tangga diantaranya sampo, sabun mandi, soda kue, detergen, kapur siri, cuka dan jeruk nipis. Hasil kegiatan menunjukkan setiap pigmen memiliki respon warna berbeda dalam setiap sampel (berdasarkan sifat keasaman/pH). Kegiatan ini meningkatkan pemahaman konsep, keterampilan ilmiah (kemampuan mengamati, mengklasifikasi, mengukur, dan mengkomunikasikan hasil),  menumbuhkan sikap ilmiah, rasa ingin tahu, dan motivasi belajar siswa.

Abstract

As a partner school, SMAN 3 Kupang Tmur, which is located in Kupang Regency, NTT Province, has several problems experienced by teachers and students for chemistry subjects, namely limited and inadequate laboratory equipment, the need for very minimal and insufficient practical materials so that activities Practicums are very rarely carried out due to the very expensive cost of materials, the unavailability of good and clear practicum guides, limited time availability from teachers due to the absence of laboratory assistants, and also insufficient laboratory space. Seeing these obstacles, in this activity teachers and students need to be provided with introductory chemistry practical activities because through practical activities they can increase students' knowledge and can provide illustrations or introduce important concepts of chemistry, train students to improve their reasoning, imagination and thinking skills. rational in seeking the truth, training students to apply scientific attitudes such as curiosity, perseverance, thoroughness, caution, objectivity, in dealing with all problems so that they do not easily believe in something that is not certain to be true, and making students more active in thinking and acting in their efforts search for truth or evidence of a theory being studied. Seeing the problems above and remembering how important practicum activities are in learning chemistry, practicum activities in schools will continue. The result of this activity is an increase in laboratory management skills and process skills by the students of SMAN 3 East Kupang.

Abstract

Pembelajaran IPA berbasis praktikum dapat disebut sebagai salah satu cara untuk mencapai hasil belajar peserta didik karena pembelajaran IPA berbasis praktikum memiliki kontribusi terhadap hasil belajar peserta didik dalam ranah psikomotorik. Di dalam kegiatan praktikum sangat dimungkinkan adanya penerapan beragam keterampilan proses sains sekaligus pengembangan sikap ilmiah yang mendukung proses perolehan pengetahuan (produk keilmuan) dalam diri peserta didik. Berdasarkan hasil wawancara dengan guru IPA SMP Negeri 18 Kupang, pembelajaran selama ini lebih difokuskan pada pemahaman kognitif sedangkan keterampilan proses sains peserta didik kurang diasah melalui praktikum IPA sehingga keterampilan proses sains peserta didik khususnya kelas VIIA dan VIIB masih rendah. Hal ini disebabkan oleh keterbatasan alat dan bahan praktikum di sekolah. Untuk mengatasi masalah tersebut maka peserta didik perlu dilibatkan secara aktif dalam pembelajaran berbasis praktikum. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk melatih keterampilan proses sains peserta didik SMP Negeri 18 Kupang melalui kegiatan praktikum IPA terpadu. Metode yang digunakan dalam pelaksanaan kegiatan ini yakni metode praktikum/eksperimen dan diskusi. Hasil kegiatan ini adalah keterampilan proses sains peserta didik menjadi lebih baik melalui praktikum IPA Terpadu dengan persentase rata-rata kemunculan keterampilan proses sains peserta didik kelas VIIA dan VIIB berturut-turut adalah 81,67% (baik) dan 81,25% (baik). Respon peserta didik terhadap kegiatan praktikum IPA Terpadu baik, dengan persentase rata-rata yang diperoleh dari angket respon peserta didik berturut-turut adalah 85,41% dan 88,02%.
