Abstract

Pesticides are used in various fields or activities, ranging from household, health, agriculture, besides their benefits, pesticides also have the potential to poison and eradicate other living things, including useful plants and insects, animals and humans. This study aims to determine the pesticide residues with the active ingredient Dimethoat in large red chili plants (Capsicum annum L.). This type of research is an experiment using gas chromathography (GC). The results of this study were pesticide residues on large red chili plants (Capsicum annum L.) above the residual minimum limit (BMR) of 0.05-7 mg / kg in three samples, sample I 127.7504 mg / kg with a percentage of 1.825%, samples II amounting to 30.0019 mg / kg with a percentage of 428% and in Sample III amounting to 58.8435 mg / kg with a percentage of 840%. The conclusion of this study is that farmers use pesticide doses not to use measurable doses, mix the types of pesticides not according to the rules and do the spraying as needed.

Abstract

Penelitian ini bertujuan untuk mengetahui lietrasi sains melalui model pembelajaran inkuiri terbimbing. Penelitian ini dilaksanakan di SMPN 10 Kota Bima. Desain penelitian menggunakan pos-test control groups only design. sampel dipilih menggunakan tehnik sampel jenuh, siswa kelas VIIa berjumlah 30 siswa sebagai kelas eksperimen dan kelas VIIb berjumlah 30 siswa sebagai kelas kontrol. Instrumen yang digunakan dalam penelitian ini menggunakan soal tes literasi sains yang memuat indikator aspek konten sains, aspek konteks sains, dan aspek proses sains. Hasil penelitian menunjukan bahwa kemampuan literasi sains siswa pada aspek  konten  sains  kelas kontrol sebesar 58,01% pada kategori cukup, kelas eksperimen  sebesar 71,78% dalam kategori baik, pada aspek penguasaan  konteks  sains   kelas kontrol  masih  sangat  rendah  yakni 38,44% dan kelas eksperimen sebesar 78,22% dengan kategori baik, sementara aspek kemampuan proses sains persentase kelas kontrol sebesar 68,20% dengan kategori baik, dan kelas eksperimen sebesar 87,21% dengan kategori sangat baik. Dapat disimpulkan bahwa model pembelajaran inkuiri terbimbing berpengaruh terhadap kemampuan literasi sains siswa yang meliputi konten sains, konteks sains, dan proses sains siswa.
