Abstract
This study aims to assess the effect of various types and varieties of organic mulch on the quantity and quality of cabbage plants ( Brassica oleraceae L.) at various altitudes. This research using Random Design Group (RDG) arranged as factorial by 2 factors. The first factor is testing four varieties of cabbage: V1 (KK-Cross), V2 (Grand 11), V3 (Silvia), V4 (Talents). The second factor is testing a variety of organic mulch: M0 (without mulch), M1 (rice straw mulch), M2 (rice husk mulch). The results showed that the KK Cross varieties have crop weight (1226.11 g) or 49 tons haa -1 heavier than other varieties at an altitude of 110 meters above sea level. At an altitude of 400 meters above sea level Grand 11 Varieties resulted in crop weight (1125.00 g) or 45 ton ha -1 is heavier than other varieties. Furthermore, at an altitude of 1350 meters above sea level Grand 11 varieties produce crop weight (1055.56 g) or 42.2 tons ha -1 heavier than other varieties. 3). Rice straw mulch is better at producing crop volume (985.25 ml) than other organic mulch treatment at an altitude of 110 meters above sea level. At an altitude of 400 above sea level rice husk mulch is better (831.83 ml) in producing the crop volume and at an altitude of 1350 meters above sea level treatment without mulch is better (984.83 ml) in volume produces of crop compared to other treatments 4). Indicators of crispy on cabbage planted at an altitude of 110 meters above sea level is the Talent without mulch and mulch varieties of rice husks and varieties Grand 11 mulched straw and rice husks. At an altitude of 400 meters above sea level the crispy indicators are on the variety KK Cross with straw rice mulch. At an altitude of 1350 meters above sea level crispy indicators contained in all varieties that were given rice straw mulch and KK Cross varieties with rice husk mulch. Keywords : Mulch, Quality, Quantity and Cabbage.
Highlights
Various studies of food consumption in general revealed that the consumption of vegetables and fruit per capita income has greater income elasticity than the food consumption of carbohydrates and the elasticity values are greater in households with higher income levels

Summary
Various studies of food consumption in general revealed that the consumption of vegetables and fruit per capita income has greater income elasticity than the food consumption of carbohydrates and the elasticity values are greater in households with higher income levels. The Increased per capita consumption is expected to be faster in urban areas than rural areas because the income elasticity of fruit and vegetable consumption tends to be higher in urban areas. This trend may occur because the income of the urban population is greater than the villagers and changing consumption patterns associated with social dynamics such an understanding of the nutrients in general are better in the city area. That fact becomes initial data to be used as a benchmark in the development of cabbage commodity This is corroborated by the results of the analysis of the World Bank in 1991, the demand for vegetables in Indonesia is projected to increase by 5 percent per year between 1998 and 2010. Cabbage plays an important role in the food industry of the country, because it can be processed into a variety of dishes from street food stalls to five star hotels
