Optimization of sago pulp bokashi with addition of adhesive and drying methods

Abstract

The purpose of this study was to assist the use of organic fertilizer at farmer level. This study used Group Randomised Design factorial with 3 factors. The first factor is the long drying time (T) consisting of 3 (three) levels, namely 0 day (T1), 1 day (T2), and 2 days (T3). The second factor is the drying type (P) consisting of two levels, namely indoor (P1) and outdoor (P2). The third factor is the adhesive material (A) consisting of three levels, namely 0% (A1), 2.5% (A2), and 5% (A3). Samples were then analysed for Most Probable Number (MPN), pH, carbon test, nitrogen test, C/N ratio, and crop test. The results showed drying time (T) has a very noticeable effect on Most Probable Number, moisture content, pH, carbon element, nitrogen element, C/N ratio, and crop test. The type of drying (P) has a very noticeable effect on Most Probable Number and crop test. The adhesive material (A) has a very noticeable effect on Most Probable Number, pH, nitrogen element, C/N ratio, and crop test. The prolonged interaction of drying and drying type (TP) is very noticeable in the Most Probable Number, and crop test. Prolonged interaction of drying and drying type (PA) is very real impact and crop test, as well as a noticeable effect on the temperature of the bokashi. Long-drying interactions and drying type (TPA) have a noticeable effect on the growing bokashi test temperature. The best bokashi granule was produced in T2P1A1 sample.
