Abstract

Fish organic fertilizer has a high nutrient content for plants. Giving organic fish fertilizer to cabbage can increase the growth and production of cabbage. This study aims to determine the way and the right dose of organic fish fertilizer in cabbage plants. This research was conducted at Berastagi experimental farm which began in June - September 2018. The experimental design used was a Randomized Block Design factorial with 3 replications, where the first factor is the type of Fish organic fertilizer (I1. Dry and I2. Fermentation). The second factor is the dose of fish organic fertilizer (D0. 0, D1. 300 kg / ha, D2. 600 kg / ha, D3. 900 kg / ha and D4. 1200 kg / ha). The results showed that the fish organic fertilizer with types dried and fermented were not different significant in increasing the growth and production of cabbage plants. The dose of fish organic fertilizer can increase the growth and production of cabbage plants. Giving 1,200 kh / ha of fish fertilizer yields the highest diameter of crop, crop weight and production, ie 14.83 cm, 0.64 kg and 30.36 kg / 5 m2. There is no interaction between type and dose of fish organic fertilizer on the growth and production of cabbage plants.

Abstract

Carrots are horticultural plants that have high economic value opportunities because every year the demand for carrots both domestically and abroad needs to increase continuously, but not maximum productivity due to the provision of organic fertilizers that are not balanced with chemical fertilizers in the soil. The research objective was to obtain animal manure fertilizer with the best dosage of fertilizer for growth and yield of carrots as an alternative to mixing chicken manure. The study was carried out in the berastagi experimental garden in February to May 2018. The experiment was arranged based on a 2-factor complete randomized trial design namely: the first factor is the type of organic animal waste pesticides consisting of H0 = Control / without treatment, H1 = chicken manure, H2 = cow / cow dung, H3 = horse manure and H4 = goat manure. The second factor is the level / dose used, namely K0 = control, K1 = 500 g / 2 m2, K2 = 1000/2 m2 repeated 3 times. Carrot samples per plot of 200 tubers. The observed variables:) Percentage of living plants (60 days), 2) Number of Compound Leaves, 3) Plant Height, 4) Wet yield weight per plot (kg) and 5) Root tuber length (cm). The results showed that the administration of organic fertilizer from cow manure had a significant effect on all parameters, namely growth percentage, plant height, yield weight and root tuber length. The dose of animal manure organic fertilizer is ideal for growth and production of carrots, which is 500 gr / 2 m2.

Abstract

In this study, there are several things that can describe the socio-economic conditions of farmers having differences in income, education, and health levels, among others: 1. The highest level of income is in Siosar Suka Meriah Village, because they receive government assistance in the form of land, funds , subsidized fertilizers, and seeds, while in Kuta Tengah Village Shelter the income is lower because the government only provides temporary shelter. The lack of capital also caused the lack of income and land to not allow farming because it was located on the slopes of Mount Sinabung. 2. The education level in Siosar Suka Meriah Village is lower, because after moving to relocation the distance to school is too far and some children do not want to continue their education. Whereas in Kuta Tengah Village Shelter their education is higher, because the distance to school is not too far away and most children also have the desire to go to school. 3. The health level in Siosar Suka Meriah Village and the level of health in the Kuta Tengah Village Shelter together use BPJS / KIS which is programmed by the government for the Mount Sinabung eruption refugee community.
