Abstract

Penggilingan padi milik Ibu Sri berdiri sejak tahun 2011, setiap harinya dapat menghasilkan beras sebanyak 3 ton. Hasil pengukuran kadar debu rata-rata 8 jam sebesar 39,64 mg/m3. Hasil tersebut melebihi standar Kepmenkes No.1405 tentang persyaratan debu di ruang industri yang batas maksimalnya sebesar 10 mg/m3 per 8 jam. Metode penelitian yang digunakan adalah observasional analitik. Hasil dari penelitian ini menjelaskan efektivitas alat tersebut dalam menurunkan kadar debu sebesar 78,83%. Kadar debu sebelum rata-ratanya 94,91 mg/m3, setelah menggunakan alat penyaring udara Turbo7 rata-ratanya 20,1 mg/m3. Berdasarkan uji paired T tes disimpulkan bahwa ada penurunan kadar debu sebelum dengan sesudah, tetapi penurunannya tidak signifikan. Prinsip kerja Turbo7 yakni menyedot udara dan menyaringnya dengan filter di dalam alat tersebut. Media filter yang digunakan adalah kain tile, arang, serta dakron. Penurunan yang terjadi masih belum memenuhi standar Kepmenkes No.1405, oleh karena itu alat ini perlu dievaluasi kembali terutama pada kipas inlet yang daya hisapnya kurang baik. Dapat disimpulkan terjadi penurunan kadar debu sebelum dengan sesudah menggunakan alat Turbo7. Disarankan pada peneliti selanjutnya untuk  mengganti kipas inlet dengan mesin vacuum agar daya hisapnya lebih kuat.

Abstract

Keberagaman adalah salah satu ciri yang dimiliki oleh bangsa Indonesia.  Kondisi yang demikian membuat toleransi menjadi satu hal mutlak yang wajib dimiliki setiap warga negara. Isu-isu intoleran sendiri menjadi isu nasional yang memanas akhir-akhir ini. Adanya media online menambah isu intoleran semakin menyebar dan rumit. Isu tersebut seolah menjadi contoh buruk bagi siswa SD ditengah gencarnya pendidikan karakter. Lingkungan yang seharusnya memberikan contoh baik bagi anak justru menjadi model yang buruk bagi anak-anak. Salah satu cara yang paling tepat untuk mengurangi perilaku intoleran adalah terus menerus mengajarkan mengenai perilaku-perilaku toleransi pada siswa melalui pembelajaran karakter di sekolah. Salah satu cara yang tepat adalah menggunakan sosiodrama. Dengan parktik melalui sosiodrama, siswa bisa merasakan pengalaman langsung dari topik yang sedang dibahas sehingga pengalaman-pengalam itu akan lebih menancap pada ingatan siswa. Berdasarkan data selama eksperimen didapatkan kesimpulan bahwa sebagian besar siswa mampu menangkap tujuan utama dari sosiodrama, minat siswa terhadap kegiatan sangat tinggi.

Abstract

Kemandirian belajar (self-directed learning) adalah salah satu faktor yang paling mempengaruhi prestasi belajar siswa. Kemandirian belajar (self-directed learning) merupakan kemampuan untuk mengatur dan mengelola belajarnya sendiri. Pengelolaan belajar yang didasarkan pada inisiatif sendiri memungkinkan siswa untuk belajar sesuai minat dan kemampuannya tanpa adanya paksaan dari pihak lain. Pengelolaan belajar yang baik akan berdampak signifikan untuk meningkatkan prestasi belajar siswa. Penelitian eksperimen ini bertujuan untuk menguji strategi individual learning plans sebagai media untuk meningkatkan kemandirian belajar siswa SMP. Individual learning plans dipilih karena metode perencanaan belajar ini memiliki keunggulan-keunggulan, seperti self instructional, stand alone, self contained, adaptive dan use friendly. Hasil dari penelitian ini menunjukkan bahwa strategi individual learning plans mampu meningkatkan kemandirian belajar siswa SMP secara signifikan. Penelitian lanjutan perlu dilakukan untuk mengetahui tingkat keefektifan strategi ini terutama pada subjek dengan karakteristik yang berbeda.
