Uji Kualitatif Kandungan Hara Kompos Campuran Beberapa Kotoran Ternak Peliharaan

Abstract

The purpose of this research is to find out the nutrient content on five types of livestock manure compost which made of the mix of some livestock manure. This research uses three stages starting from the inventory, then analyzing the data, and finally interpretation of the data for the parameters: follow-up material, color, odor, moisture or water content, Reaction Fertilizer PH, Levels of C Organic, Levels of Total N, Total P, Total K, and Fe. The inventory stage is conducted in laboratory using fast accurate qualitative methods based on Soil Research Center manual guide (2015). The research showed the results of the analysis of physical quality of blackish brown color, soil smells, moisture content less than 50% have met the Indonesian National Standard (SNI) 19-7030-2004. However, based on Decree of the Minister of Agriculture no 28/Permentan/SR.130/B/2009, the water content obtained under the requirements is only in the range of 7.82 to 13.31 from 15-25% while the follow-up material showed <2%. The test results using a set of compost test tools showed N Total content of the livestock manure mixture compost that were made in the range of 2-3% (SNI standard >0,4% and Decree of the Minister of Agriculture <6%), P2O5 1-1.5% (SNI standard >0.1% and Decree of the Minister of Agriculture <6%), C-Organic 10% (SNI standard >9,8-32% and Decree of the Minister of Agriculture >12%), and Fe content 1000-2000 ppm (Decree of the Minister of Agriculture standard 0-8000 ppm), PH 5-7 (SNI standard 6,8 and Decree of the Minister of Agriculture standard 7,49). ABSTRAKTujuan penelitian ini untuk mengetahui kandungan hara kompos pada 5 jenis kompos campuran beberapa kotoran ternak peliharaan. Penelitian ini menggunakan tiga tahap dimulai dari inventarisasi, kemudian analisis data dan selanjutnya interpretasi data untuk parameter: bahan ikutan, warna, bau, kadar air, Reaksi Pupuk pH, Kadar C Organik, Kadar N-Total, P Total, K Total, Fe. Tahap inventarisasi dilakukan di laboratorium menggunakan metode kualitatif selidik cepat berdasarkan panduan Balai Penelitian Tanah (2015). Hasil penelitian menunjukkan hasil analisis kualitas fisik warna coklatkehitaman, berbau tanah pada, kadar air kurang dari 50% telah memenuhi SNI 19-7030-2004. Namun berdasarkan SK Mentan No 28/Permentan/SR.130/B/2009, kadar air yang diperoleh di bawah persyaratan hanya pada kisaran 7,82-13,31 dari persyaratan 15-25% sedangkan bahan ikutan menunjukkan <2%. Hasil uji dengan menggunakan seperangkat alat uji kompos menunjukkan kandungan N total untuk kompos campuran kotoran ternak yang dibuat berada pada kisaran 2-3% (standar SNI >0,4% dan SK Mentan <6%), P2O5 1-1.5 % (standar SNI >0,1% dan SK Mentan <6%), K2O <1% (standar SNI >0,2% dan SK Mentan <6%), C-organik 10% (standar SNI >9,8-32% dan SK Mentan >12%),dankadar Fe 1000-2000 ppm (standar SK Mentan 0-8000 ppm), pH 5-7 (standar SNI 6,8 dan SK Mentan 7,49).
