Abstract

Pengusahaan kopi organik dapat pula dijadikan sebagai salah satu alternatif dalam meningkatkan mutu kopi robusta Indonesia. Penelitian ini dilaksanakan di Kecamatan Medan Johor, Sumatera Utara dengan ketinggian ±32 meter dpl, dari bulan Mei sampai September 2016, menggunakan rancangan acak kelompok dengan 2 faktor perlakuan. Faktor pertama adalah perbandingan topsoil dan pupuk kandang (pukan) ayam dengan 4 perbandingan volume yaitu (1:0); (3:1); (2:1); (1:1) dan faktor kedua yaitu pemberian pupuk organik cair (POC) dengan 4 taraf yaitu 0 cc/l; 2 cc/l; 4 cc/l; 6 cc/l. Parameter pengamatan adalah volume akar (cm3), bobot kering tajuk (g) dan bobot kering akar (g). Perlakuan pukan ayam berpengaruh nyata terhadap parameter pengamatan volume akar, bobot kering akar dan bobot kering tajuk. Perlakuan pemberian POC berpengaruh tidak nyata terhadap semua parameter. Interaksi pukan ayam dan POC berpengaruh nyata terhadap parameter bobot kering akar dan bobot kering tajuk.

Abstract

The purpose of this research is to know the response of robustacoffee seedling from the application of chicken manure and liquid organic fertilize. This research was held in land that are on Kecamatan Medan Johor road, North Sumatra with altitude ±32 meters above the sea level, started from May until September 2016. This research was using factorial randomized block design with 2 factors. The first factor is the application of chicken manure (topsoil:manure)with four levels, namely: (1:0); (3:1); (2:1); (1:1) and the application of liquid organic fertilizer with four levels of 0 cc/l; 2 cc/l; 4 cc/l; 6 cc/l. The observed parameters were plant height (cm), stem diameter (mm), root volume (cm3), totalleaf area (cm2), dry weight of root (g), dry weight of shoot (g), and shoot-root ratio. The result showed that chicken manure treatment significantly increased the plant height, stem diameter, root volume, total leaf area, dry weight of root, dry weight of root and shoot-root ratio. The application of liquid organic fertilizer significantly increased the total leaf area parameter. The interaction between both treatments significantly increased dry weight of root, dry weight of shoot and total leaf area parameters.
