Abstract

Penggunaan pupuk anorganik dalam sistem peningkatan produksi tanaman menimbulkan masalah antara lain menipisnya bahan baku pembuatan pupuk. Upaya mencari alternatif bahan baku yang bersifat terbarukan mendesak dilakukan antara lain penggunaan pupuk organik. Bahan alami berupa tumbuhan seperti Chromolaena odorata dan Tithonia diversifolia sudah mulai dilakukan peneliti namun informasinya masih terbatas. Pengayaan informasi terhadap tumbuhan tersebut diperlukan agar diperoleh ketuntasan sehingga dapat segera dimanfaatkan. Tujuan penelitian ini untuk mempelajari potensi C. odorata dan T. diversifolia di suatu wilayah sehingga secara praktis dapat dimanfaatkan di wilayah penelitian. Hasil penelitian menunjukkan bahwa C.odorata dan T.diversifolia di Desa Sobokarto Boyolali ditengarai berlimpah, diyakini dapat dimanfaatkan untuk pupuk karena kandungan C/N bahan segar kategori rendah. Perubahan bentuk dari segar menjadi potongan basah atau kering serta serbuk mempercepat laju dekomposisi. Selama inkubasi C/N ratio mencapai 10. Laju dekomposisi tercepat dicapai C.odorata adalah bentuk serbuk, sedangkan T.diversifolia dalam bentuk potongan basah.

Abstract

This study aimed to obtain information about physical and chemical characteristics of the peat due to addition of ash ameliorant with different dosage to get the best growth media. Ameliorant materials are litter ash / vegetation result of peatlands clearance, rice husk ash and palm bunch ash. This study used split plot design consists of two factors, ameliorant factor (A) as main plots, with 4 levels (a1 = litter ash / vegetation result of peatlands clearance, a2 = rice husk ash, a3 = trapalm bunch ash), and ameliorant dose (D) with 5 levels (d0 = no ameliorant / control, d1 = 50 g ameliorant, d2 = 100 g ameliorant, d3 = 150 g ameliorant, D4 = 200 g ameliorant / tube of peat), treatment was repeated three times and consisted of two samples, so there are 90 units of treatment. Observations were done on the weight of the content (bulk density), density of type (particle density), total soil pore space, nutrient levels of N-total, P, K, Mg, and pH of soil. The results showed that the addition of ameliorant material significantly improve the availability of P, K, Mg, and pH of the soil, but decrease N concentration of peat. Peat soil treated palm bunch ash has a greater density lindak with total soil pore space smaller than the peat treated litter ash/ vegetation peat and rice husk ash.
