PEMANFATAN DAUN TEBU KERING (DADHOK) DENGAN PENAMBAHANBLOTONG DAN AKTIVATOR EM4 UNTUK PEMBUATAN KOMPOSDI KECAMATAN KREMBUNG KABUPATEN SIDOARJO TAHUN 2015

Abstract

Dry sugarcane leaves (dadhok) are garbages of sugar cane harvest that have not been managed
properly. One of the alternatives to reduce pollution generated is to use it as compost. This study
aims to determine content of dry sugarcane leaves as compost with the addition of blotong and
EM4 activator.
This research uses experimental design with Pre-Post Test Only Design. There were four
experiments conducted within the study: 1st
 experiment was dry sugarcane leaves (control), 2
experiment was dry sugarcane leaves + EM4 activator, 3blotong, 4thrd experiment was dry sugar cane leaves +
 experiment was dry sugar cane leaves + EM4 activator + blotong. Data was collection
by measurement and laboratory testing. Data was then analyzed descriptively by referring to the
Regulation of the Minister of Agriculture numbers 70 / Permentan / SR.140 / 10/2011 and SNI 197030-2004.

Result

shows that of the four experiments conducted, C / N ratio of compost that met the
requirement was the 2nd, 3rd, and 4th experiment but only the 3
ripe compost requirement (color, texture, smell). Compost of 2ndrd and the 4th experiments fulfilled
 experiment was not perfectly ripe
for  EM4 only reduce the value of C / N ratio but it cannot degrade the material. On experiment 1,
C / N ratio and compost ripeness did not meet the requirement. Macronutrients of all experiments
did not meet the requirement. This was because the raw material had low macronutrients.
Findings conclude that only the 3rd and the 4th experiments meet the requirement of Permentan
Regulation number 70 / Permentan / SR.140 / 10/2011 and SNI 19-7030-200. Experiment 1 and 2
were not qualified. Findings suggest sugar mills to distribute the abundant waste of blotong to
farmers that it can be used with dry sugarcane leaves as compost. For community who posses
sugar cane plantations, sugarcane leaves can be used as compost that they can use it to increase
their income.
