Abstract

The study aimed to was determine the effect of dose and time of fertilization bio-slurry liquid fertilizer on the growth and yield of sweet corn was held in Tanjung Laut, Fajar Baru village, Jati Agung district, South Lampung regency in October 2016 to January 2017. In this study used Randomized Block Design (RBD) with factorial treatment design (4 x 2) with three replications. The first factor was the dose of bio-slurry liquid fertilizer consisted 4 levels were 0, 25, 50, and 75 l/ha. The second factor was the fertilization time consisted of 2 levels were (2 and 4 MST) and (2, 4, and 6 MST). Variance of homogeneity was tested by Bartlett's test, if the assumptions were met, the data were analyzed by variance using F-test. The difference of median value of treatment will be tested by the Least Significance Difference Test (LSD) at 5% level. The results showed that the treatment of several doses of bio-slurry liquid fertilizer has an effect on the length of cob, while the treatment of some fertilization time has an effect on dry weight variables. However, the treatment of some dose levels and fertilization time of bio-slurry liquid fertilizer has not been able to increase growth and yield. Proper fertilization time does not depend on the dose of bio-slurry liquid fertilizer given in influencing the growth and yield of sweet corn crops.

Abstract

The development of alternative energy which is sourced from cow manure has good prospect to fulfill domestic needs of society. There is one way that can be done by turning farm waste, especially cow manure, to alternative energy as the substitution of fuel in form of biogas. The aim of the study was to analyze developing strategy of biogas as domestic alternative energy by making use of cow manure in Sari Bhakti village, District of Seputih Banyak in Region of Lampung Tengah. The method used in this study was SWOT analysis. Respondents were selected purposively (purposive sampling) from Sari Bhakti village, district of Seputih Banyak with the total sample were 25 cow farmers and 4 experts who have the competence in developing biogas from cow manure. The research finding showed that based on the result analysis of SWOT metrics, recommendation that should be given is „progressive strategy‟. Alternative strategy that can be applied is by utilizing cow farming group to get support from the governance in order to decrease the pollution of environment and to increase the prosperity of society, moreover, increasing socialization of biogas as domestic alternative energy is essential to increase the role of farming group in innovating technology of alternative energy.
