Abstract

Impact of Climate Change (DPI) in West Java, especially the agricultural sector (food) are strongly influenced by the shift early growing season occurs 2 to 4 weeks since last 5 years. Some areas on the North Coast (North Coast of Java) early season retreat 1 to 2 months. As a result it affects the decline in production and productivity of rice, the price fluctuations of agricultural products and food insecurity disturbing. Purpose of the study looked at the impact of climate change on the productivity of rice paddy fields at the time of drought and floods and how the wisdom of farmers to cope with climate change. The research location Indramayu regency, as it is the central areas of rice-based food production, and the area has the insecurity of the impacts of climate change. The results showed the presence of DPI on the applied local wisdom flooded farmers (a) using the short-lived rice varieties, (b) rice varieties resistant varieties will be flooded and planted in one stretch with monoculture cropping systems. (C) use a pump to remove water . Dry season activities were implemented: (a) promote the planting schedule, (b) create a nursery, (c) use early maturing varieties, (d) cross dams, (e) motion to eradicate rats, (f) spray white butterfly pests (borers rods), (g) irrigation cultivation rationed sleigh, (h) conduct ceremonies (salvation alms earth), (i) and down motion field simultaneously. Productivity of rice under normal conditions GKP 5 tons gkp / ha (R / C 2.21). While the impact of flooded rice productivity on average only up to 3.5 tonnes gkp/ ha (R / C 1.01). Impact of drought rice productivity was only 4 quintals / ha (R / C 0:24).

Abstract

Beetroots are a type of tubers with a distinctive purplish red color and are beneficial for health with a high amount of betasianin as an antioxidant, as well as its use in preventing infection. But the beetroot is less liked by the public because of the strong enough earthy taste, so it is necessary to do new innovations for the product to be accepted by the community, one of which is the functional beet syrup drink. To create a preferred flavor, the addition of other food additives and sweetener stevia which has a sweetness level of 200-300 times that of sugar and includes non-calorie sweeteners is done. This study aims to analyze the best concentration of stevia extract on the sweetness level and beetroot characteristics and determine the level of panelists' preference for beetroot syrup (Beta vulgaris L.) with organoleptic tests. This research was conducted with a randomized block design (RBD), the data were analyzed by variance (ANOVA), if the data obtained were significantly different, the DMRT would be further tested at 5% level. The results showed that the highest betasianin was in the SBS15 treatment (31.74 mg / l), the highest total dissolved solids was in the SBS treatment (3.25ºBrix), the highest pH was in the SBS15 treatment (4.22), the highest vitamin C was in the SBS15 treatment (11.66 mg ascorbic acid / 10 ml). Organoleptic results showed that beet syrup with the addition of stevia extract of 6% was the most preferred sample by panelists.
