Abstract

Penelitian ini dilakukan karena adanya masalah yang peneliti temukan tentang populasi lintah yang banyak di lingkungan Desa Bawootalua.Dalam hal ini peneliti mencoba memanfaatkan ekstrak nanas untuk membasmi lintah, karena tanaman nanas ini memiliki zat bromelin yang mampu membunuh lintah serta ramah lingkungan.Penelitian ini bertujuan untuk melihat mobilitas dan mortalitas lintah. Dan peneliti melakukan uji coba sebanyak empat perlakuan yaitu P0, P1, P2, dan P3 dengan takaran ekstrak nanas yang berbeda-beda yakni 30 ml, 75 ml, dan 100ml. Penelitian ini merupakan jenis penelitian deskriptif dengan pendekatan kualitatif dengan jumlah informan 8 (delapan) orang. Teknik pengumpulan data dengan wawancara dan observasi.Teknik analisis data menggunakan metode analisis data menurut Sugiyono terdiri dari tiga tahap yaitu reduksi data, penyajian data dan penarikan kesimpulan.Hasil penelitian ini adalah melihat efektivitas ekstrak nanas terhadap mobilitas dan mortalitas lintah dengan takaran yang telah ditetapkan.Kesimpulan penelitian ini adalah bahwa pemanfaatan ekstrak nanas sebagai pembasmi lintah menimbulkan reaktif mobilitas dan mortalitas lintah dengan takaran 100 ml yang paling cepat.Jadi ekstrak nanas ini dapat dimanfaatkan masyarakat sebagai herbisida alami untuk membasmi lintah.Saran, diharapkan semoga masyarakat mampu beralih ke herbisida alami yang ramah lingkungan agar tekstur tanah tetap terjaga kesuburannya.

Abstract

Pembelajaran saat ini dilakukan melalui jaringan atau daring akibat wabah Covid-19, sehingga pembelajaran tidak dapat dilakukan secara langsung atau tatap muka di sekolah seperti biasa. Pembelajaran daring di era wabah Covid-19 tentunya berbeda dengan pembelajaran tatap muka, khususnya dari segi implementasi kurikulum 2013 yang diterapkan saat ini. Tujuan penelitian ini yaitu untuk mengetahui implementasi kurikulum 2013 dan pengawasan implementasi kurikulum 2013 yang dilakukan pengawas tingkat SMP di era wabah Covid-19 di kabupaten Nias Selatan. Jenis penelitian ini adalah penelitian deskriptif dengan pendekatan penelitian kombinasi (Mix Methods). Penelitian ini dilaksanakan di kantor Satuan Pendidikan Nias Selatan dengan informan para pengawas sekolah tingkat SMP yang berjumlah 10 orang. Adapun intrumen yang digunakan berupa angket. Teknik analisis yang dilakukan dengan tiga tahap yaitu penyajian data, reduksi data dan penarikan kesimpulan/verifikasi. Dari hasil penelitian implementasi kurikulum 2013 di era wabah Covid-19 masih tergolong kurang. Kekurangan ini terlihat jelas pada proses pembelajaran yang tidak dilakukan di lingkungan persekolahan serta sarana prasarana yang tidak memadai selama proses pembelajaran. Pengawasan pelaksanaan kurikulum 2013 tetap dilakukan para pengawas tingkat SMP sesuai dengan regulasi yang ada. Saran yang dapat diberikan peneliti, kiranya satuan pendidikan telah menyiapakan berbagai pilihan dalam melaksanakan proses pembelajaran dalam menghadapi kondisi yang tidak diiginkan guna tercapainya kurikulum yang telah diberlakukan.
