Karakteristik Fisik dan Kimia Sagu Parut Kering (Sapuring) Sebagai Bahan Pakan Alternatif

Abstract

Total areal sagu di dunia adalah 6,5 juta ha dan Indonesia memiliki lahan sagu 5,5 juta ha, pemanfaatan sagu di Indonesia kurang dari 5%. Penelitian bertujuan mengkaji karakteristik fisik dan kimia sapuring sebagai bahan pakan alternatif. Penelitian menggunakan Racangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 ulangan. Perlakuan yang digunakan yaitu, utuh (P1), penyaringan mash 30 (P2), peremukan dan penyaringan mash 30 (P3). Data diuji ANOVA dilanjut uji Duncan. Parameter yang diukur yaitu sifat fisik; kerapatan tumpukan, kerapatan pemadatan tumpukan, ukuran partikel, sudut tumpukan, dan berat jenis. Sifat kimia; analisis proksimat (bahan kering, abu, protein kasar, lemak kasar, serat kasar, bahan ekstrak tanpa nitrogen), gross energy, serat kasar, dan kelarutan total. Hasil ukuran partikel pada P1 688,42 μm; P2 371,18 μm dan P3 370,81 μm. Berat jenis untuk P1 0,86 g cm-3, P2 1,11 g cm-3 dan P3 1,25 g cm-3. Analisis proksimat bahan kering 87,94-88,11%, abu 3,31-4,00%, protein kasar 2,51-3,44%, lemak kasar 0,11-0,18%, serat kasar 2,36-5,19%, dan bahan ekstrak tanpa nitrogen 76,53-78,72%. Gross energy memiliki hasil 3509-3620 kkal kg-1, kelarutan total 14,65-16,36%. Penyaringan dengan mash 30 dapat mengurangi serat kasar hingga 55%. Berdasarkan hasil penelitian, sapuring dapat dijadikan sebagai bahan pakan alternatif.

The area of sago in the world is 6,5 mio ha and Indonesia has 5,5 mio ha of sago land, the application of sago in Indonesia is less than 5% of total potential. The purpose of this study was to examine the physical and chemical characteristics of sapuring as an alternative feed ingredient. The study used a Completely Random Design (CRD) method with 3 treatments and 3 replications. The treatments applied, whole (P1), sieving with mash 30 (P2), crush, and sieving with mash 30 (P3). The results were analyzed by ANOVA and continued with Duncan's test. The parameters are physical characteristics; bulk density, compact bulk density, particle size, angle of repose, and specific density. Chemical characteristics; proximate analysis (dry matter, ash, crude protein, crude lipid, crude fiber, nitrogen free extract), gross energy, crude fiber, and total solubility. The results of the physical characteristic were particle size at P1 688,42 μm, P2 371.18 μm, and P3 370.81 μm. specific density for P1 0.86 g cm-3, P2 1.11 g cm-3 and P3 1.25 g cm-3. Chemical characteristics of the proximate dry matter 87.94-88.11%, ash 3.31-4.00%, crude protein 2.51-3.44%, crude lipid 0.11-0.18%, crude fiber 2.36-5.19%, and nitrogen free extract 76.53-78.72%. Gross energy has a result of 3509-3620 kcal kg-1 and a total solubility of 14.65-16.36%. Sieving with mash 30 can reduce crude fiber until 55%. Based on the results sapuring can be used as an alternative feed
