Abstract

Food crops information systems in Kabupaten Karo (rice and pulses), still manual/conventional and still less effective and in efficient. To overcome the inferiority, we need a system that can deliver the information in a timely and accurately. Information systems in food crops (rice and pulses) web-based solution that is right. Information systems web-based food commodities was containing information about the condition and potential of  food crops. The system was designed based on the  user needs using the PHP programming language, MySQL database and the web Apache web server using rapid application development (RAD), which was a very short development method with quick application technique

Abstract

This research is about fruit picker tool on different type of fruit trees. This research was conducted to test the fruit picker tool on various type of fruit trees i.e melinjo, tamarind and rambutan to determine the effective capacity of the tool, the percentage of defects and field capacity of the tool. The research was conducted in Tridharma, A. H. Nasution and Bunga Mawar Roads from February to August 2012 using non-factorial completely randomized design with melinjo, tamarind and rambutan trees. The parameters measured were the effective capacity of the tool, the percentage of defect and tool field capacity tool. The results Showed various types of fruit trees had highly significant effect on the effective capacity of the tool and the percentage of defect had no significant effect on the capacity of the field. The best result was on rambutan fruit i.e 30.54 kg h-1 with the percentage of defects of 7.3%.

Abstract

This research was aimed to test the effect of different mesh sizes on the quality of coffee beans in the multifucer grinder using roasted arabica and robusta coffee beans. The parameters measured were the effective capacity of the equipment, the percentage of material that passed the sieve, coffee powder moisture content, percentage of soluble coffee powder in water and organoleptic tests. The results showed that the best effective capacity was 35.56 kg/hour for the treatment of robusta coffee with 250 mesh sieve, the percentage of material that passed the sieved was 93.33% for Arabica coffee at 150 mesh sieve. The best coffee powder water content was 2.43% for Arabica coffee at treatment with 250 mesh sieve. The best percentage of soluble coffee powder was 33% at 250 mesh sieve. The best aroma was 3.9, which means that the aroma was very typical for treatment of 250 mesh sieve. The best taste was 3.46, which means the taste was typical for Arabica coffee at 250 mesh sieve. The quality of coffee powder produced from the grinding was in compliance with the quality standards of Indonesia. Key words: multifucer, sieve, mesh, robusta coffee, arabica coffee.

Abstract

Roasting is an important step in the production of coffee powder, wherein the formation of aroma and distinctive flavor of coffee is determined at this stage. Of the national production of coffee beans, only 20% are processed and marketed in the form of secondary products such as roasted coffee, ground coffee and instant coffee. This study was plan to build a rotary mechanical device of coffee roasters. The study was conducted with literature study, experiment, observation and testing of the tool. The parameters measured were the effective capacity of the tool. The results showed that the effective capacity of the coffee roasters was 2.151 kg.hour-1. Key words: postharvest equipment, coffee, roasting, effective capacity.

Abstract

Soybean plants were flooded for a long time will inhibit the growth and yield of soybean. For that, there should be proper drainage, in order to cope with flooding due to decreased plant productivity. This study aimed to assess the effect of long inundation on the growth of soybean plants using Andosol soil. Measure variable is water quality, physical properties soil and soybean production. The results indicate that water quality parameters waterlogged conditions 3 days whereas the dissolved oxygen, in the affect the physical properties of soil is the pH of the soil, with soybean production (2 plants / pot) 96 pods. On the waterlogged conditions until wilted/dead water quality parameters  affect the dissolved oxygen and pH of the water, in the affect the physical properties of soil is the pH of the soil, with soybean production 36 pods. On the condition of field capacity water quality parameters and physical properties of soil in accordance with the terms optimal growth of soybean plants, with soybean production 241 pods. Keywords: water quality, soil physical properties of Andosol, the growth of soybean plants

Abstract

Milling was done to refine food materials to be powder with a certain sieve size in order to be more easily processed into other products. The purpose of coffee beans milling was to refine the beans into coffee powder with a certain sieve size in order to be easily brewed and gives the more optimal sensation of taste and aroma. This research was aimed to design, make, and evaluate the flat burr mill type of bean grinder on robusta cofee bean. The bean quality evaluated was the effective capacity of grinder mill, lost bean persentage, and economical analysis. The results showed the effective capacity of flatt burr type grinder was 5,00 kg/hr and the lost bean persentage was 1,112%. Based on economical analysis, the cost of robusta coffee bean milling was Rp.1.074,25/kg, break even point 2.748,9 kg/year, net present value (NPV) 16% was Rp.6.147,25 ,NPV 20% was Rp.5.397.751,98, and Internal Rate of Return (IRR) was 52.81%. Keywords : Coffee, flat burr mill, grinder, rotor, stator.
