Abstract

Analysis of Marketing of Rawitic Chili (Capsicum frutescens L.) in Barusjahe District, Karo Regency. The method of determining farmer samples was carried out in Simple Random Sampling where the number of chili farmers in the village was 80 kk (head of household), and 20 kk was taken for samples. Data collected in this study consisted of primary data and secondary data. Primary data is obtained through direct interviews with farmers and traders using questionnaires that have been prepared previously. Secondary data was obtained from the Karo District Agricultural Service, Channels of cayenne marketing in Sikab Village were divided into two, namely cayenne which was sold to the market (first channel non Ped. Regency collector with a capacity of 74.8 tons) and cayenne sold to the market (second channel through Ped. Collector District with a capacity of 22.6 tons. The results showed that the marketing of cayenne in Karo District has Components of Cost, Price Spread and Share of Cayenne Margin through Marketing Channels I per One Pick up (1.5 tons) Buy Prices Raw Chili from Farmers Rp. 15,000 / kg @ 1,500 kg = 30,000,000, Consumer purchase price Rp. 30,000 / kg @ 1500kg = 45,000,000, - so the Total Profit Margin is 19,364,435. Component Cost, Price Spread and Share of Cayenne Margin through Marketing Channels II per One Pick up (1.5 tons) Buy Prices for Raw Chili from Farmers Rp. 15,000 / kg @ 1,500 kg = 22,500,000, Consumer Purchase Price Rp. 30,000 @ 1500 kg = 45,000,000 so Total Profit Margin 19,184,740, -. From the results above, we can see that the marketing of cayenne through channel I is more efficient than marketing chili through channel II. This happens because the marketing efficiency value in channel I is smaller than the marketing efficiency value on channel II.

Abstract

The effect of Mt. Sinabung eruption has profoundly affected the quality of fruit and vegetable production, in this context is fruit and vegetables. Fruit and vegetable, carrot, strawberry and pakcoy is kind of fruit and vegetable that is consumed by the community especially the communities surrounding both the mountain ranges and the general medan area. The fruit and vegetable are kinds of climateric and the lifespan must be kept. During the transportation of field to market, there wa both mechanical and physical damage.The damage will obviously harm farmers, merchants, and other marketers. So that hydrocooling is applied as a post harvest treatment. Hydrocooling is done right after the harvest, This prosess extracts heat from fruit and vegetables so that respiration and transpiration can continue for a long time.The lack of farmer understanding for post harvest handling is a major problem. Therefore, farmers in aberastagi will be given education and training about post harvest handling (hydrocooling) so they could understand and self applying that will keep their produce fresh. As for the output of this activity is a simple hydrocooling device designed as a visual aid in training. This hydrocooling equipment can also be a reference to training science for schoolchildren in particular agriculture schools and could be a referenceto researchers and developing them.
