ENERGY AND ECONOMIC ANALYSIS OF ICE CREAM STICK PRODUCTION WITH BRINE TANK MACHINE

Abstract

Ice cream stick is a food product so much favored by Indonesian. Generally, ice cream is categorized based upon composition, taste, colour, shape and size, and to produce it, a sum of energy is required that will affect production cost of ice cream production machine. Energy and economic cost production will help to reduce cost one stick and feasibility this business provided Net Present Value (NPV) and Internal Rate od Return (IRR). With the analysis it is expected that home industry scale of this business can be developed. Brine tank machine is a box shaped machine equipped with cooling cycle and able to produce 280 of ice cream sticks one cycle. Result of the research shows that energy input, energy output, production capacity one hour, base cost one stick, selling price one stick, BEP, NPV 16% and IRR for interest rate 20% are as follows : 87.480 kJ; 43.546,05 kJ; 0,5; 210 stick; Rp 3.842; Rp 4.456; 33 stick; Rp 1.238.039.411 dan 22,55 %. Base cost can be reduced by using less expensive ice cream ingridients but it will increase the amount of ice cream stick to be produced and sold to meet the BEP and decreases IRR
