Pengertian Limbah Pertanian

Kali ini kita akan membahas Pengertian Limbah Pertanian. Limbah pertanian adalah bagian tanaman pertanian diatas tanah atau bagian pucuk, batang yang tersisa setelah dipanen atau diambil hasil utamanya. Berdasarkan artinya Pengertian Limbah Pertanianpengertian limbah pertanian dapat diartikan sebagai bahan yang dibuang di sektor
pertanian. Beberapa contoh limbah pertanian diantara lain adalah sabut dan tempurung kelapa,jerami dan dedak padi, dan sebagainya.

Limbah pertanian dapat diklasifikasikan ke dalam beberapa jenis yaitu limbah pra panen dan
saat panen serta limbah pasca panen. Sedangkan limbah pasca panen itu juga terbagi menjadi limbah sebelum diolah dan limbah setelah diolah atau sering dikenal dengan limbah industri pertanian.

Apakah limbah pertanian dapat dimanfaatkan?


Ya limbah pertanian sebagian dapat dimanfaatkan. SebagPengertian Limbah Pertanianai contoh limbah pertanian dapat dijadikan sebagai pakan ternak. Namun pemanfaatan ini masih tergolong rendah. Contoh lain adalah limbah pertanian jerami padi/jagung/ ubi jalar, pada dasarnya limbah ini dapat digunakan sebagai pupuk organik, akan tetapi petani lebih sering membakarnya setelah panen. Sangat disayangkan bukan. Dewasa ini masih sangat minim pemanfaatan limbah pertanian, hal ini terbukti dari sebuah penelitian hanya sekitar 30% peternak di Indonesia yang memanfaatkan limbah pertanian sebagai pakan dan juga pupuk.

Limbah pertanian dapat digolongkan kedalam 4 kelompok yaitu :
  • Limbah pertanian pra panen contoh daun, ranting atau buah yang gugur sengaja atau tidak.
  • Limbah pertanian panen contoh batang atau jerami saat panen padi.
  • Limbah pertanian pasca panen contoh kulit atau jeroan pada ternak potong.
  • Limbah industri pertanian contoh molases pada pabrik gula tebu.

Limbah pertanian untuk pakan


Meski tergolong limbah, namun jangan salah. Limbah pertanian juga memiliki kandungan nutrisi yang tinggi dan dapat dimanfaatkan sebagai pakan ternak. Dibawah ini adalah data nutrisi dari beberapa limbah peternakan.
