Utilization of The Sand from Mount Sinabung Eruption as Material for Planting Media

Abstract

Abstract-The idea of this study was to descript the output and feasibility of sand utilization from mount Sinabung eruption activities. The sand used as materials to produce planting media for vegetables. The experiment started from collecting the sand with pretreatment then added by certain material such as: waste of coffee skin after fermented as compost with goats manure, the urine of red sugar and liquid phase red sugar and then prepared to make shape by pressure tool. Hydraulic pressure tool applied to construct the matrix media with cylindrical shape variation. In this application, the shape type of matrix media was used to grow different plants such as: onion crop, local red chili,and vanilla plants. The most important result is the possibility to increase the value of sand from Sinabung eruption that can be used as planting media. The media also can be used in the certain place around the living place to increase the income of the people Sinabung victims. This idea is possible to increase the productivity of the people around the mount Sinabung.

Sucrose component in cane sugar produces better crystals than palm sugar which contains glucose and fructose [20].…”

Analysis of company operating feasibility using Energy Productivity Ratio (EPR)

“…Based on the data obtained, the calculation of energy input and energy output, so it can be calculated value of Energy Productivity Ratio (EPR) company [5,6].…”

“…Effectiveness measure the amount of company target that can be reached in getting the output. Where efficiency is used to determine the amount of use of resources in a manufacturing process [3,4,5,6,7].…”

“…Whereas if the energy ratio is 1 <1 then the production of the product is declared not worth continuing. New fuel needs to be sought to reduce losses and use energy sources declared as energy-deficient energy sources and needs to be revisied [5,6].…”
