Abstract

Desa Sumberbrantas merupakan salah satu desa penghasil kentang di provinsi Jawa timur. Untuk meningkatkan kualitas dan kuantitas benih kentang, beberapa petani yang tergabung dalam kelompok tani Anjasmoro III melakukan pembenihan kentang di dalam greenhouse. Namun, letak geografis lahan pertanian yang berada di kaki gunung Arjuno menyebabkan kurangnya pencahayaan dan pembenihan kentang menjadi tidak optimal. Berdasarkan photoperiodic-nya kentang memerlukan pencahayaan maksimal 16 jam/hari, sedangkan di desa Sumberbrantas kentang hanya mendapatkan pencahayaan 10 jam/hari. Untuk mengatasi permasalahan tersebut maka dilakukan penerapan alat Lighting Automatic Potatoes Seeding (LUMOS) untuk optimalisasi pembenihan kentang di dalam greenhouse. LUMOS didesain khusus untuk memberikan pencahayaan tambahan pada pembenihan kentang di dalam greenhouse secara otomatis berdasarkan photoperiodic-nya. Dalam sistem kerjanya alat ini dibantu oleh sensor fotodioda dan mikrokontroler ATmega16. Pada penelitian ini digunakan 15 lampu TL fluora dan 3 buah sensor fotodioda untuk greenhouse pembenihan berukuran 24m x 5m. Dalam aplikasinya alat ini mampu meningkatkan diameter benih kentang hingga 8,128 mm dan penambahan massa sebesar 31,3 gram.

Abstract

Colocasia esculenta (Umbi talas) memiliki kandungan serat yang tinggi apabila dibandingkan dengan umbi ketela rambat yaitu sekitar 0,6-0,8 g/100g, dan protein sekitar 2-6g/100g yang mana kandungan ini dapat dimanfaatkan oleh tubuh manusia sebagai sumber protein dan serat yangbaik bagi tubuh manusia. Akan tetapi dengan nilai serat dan protein yang terdapat pada umbi tersebut dapat mengalami kerusakan yang dikarenakan kandungan kadar air yang tinggi, serangan mikroba dan kerusakan lain ketika pemanenan dan penyimpanan sehingga dilakukan alternatif lain yakni diolah menjadi tepung talas. Pada penelitian ini dilakukan pembuatan tepung dengan menggunakan disc mill yang bertujuan meningkatkan keseragaman ukuran butiran tepung talas yang dihasilkan serta mampu mengoptimasi produk hasil olahan. Penelitian ini menggunakan metode deskriptif dengan dua faktorial yaitu kadar air chip talas (10, 15, dan 20%) dan kecepatan penggilingan tipe disc mill (1000, 2000, dan 3000 rpm). Hasil penelitian menunjukkan bahwa chips talas dengan kadar air 10, 15 dan 20% didapatkan dalam rentang waktu 100, 85 dan 75 menit. Dengan nilai karakteristik pada perlakuan tepung talas 20% diperoleh kadar protein sebesar 4,19%, kadar lemak 0,46%, kadar abu 4,01% dan kadar karbohidrat sebesar 82,35%. Hal ini menunjukkan bahwa pengaruh kadar air chip berpengaruh terhadap karakteristik kimia dalam pembuatan tepung talas.
