This study purpose was to analyze the relationship of social capital, namely interaction, social responsibility, cultural values, cooperation and the role of village officials or other parties to the motivation of local communities. Social capital that grows and develops in the local community environment becomes a reference to increase motivation so that it can optimize the potential of sago to become a productive farm. Data were analyzed quantitatively using a Likert scale technique and correlation to determine the relationship of social capital to the level of motivation and are described descriptively. The location was chosen purposively or deliberately, the location of the study was conducted in a mooring village, with 50 respondents. The results showed that social capital was strongly related to the level of motivation in optimizing the potential of sago farming.
This study has been conducted in an agricultural hilly area of Karo District, in North Sumatera Province, Indonesia. The study was conducted in May until July 2016. The objective of this study is to analyse slurry characteristics as organic fertilizer in which biogas is used to yield better slurries. Five biodigesters were used with 5 differents designs of mix materials: T1) 100% cow feces, T2) 75% cow feces + 25% argicultural waste, T3)50% cow feces + 50% agricultural waste, T4) 25% cowfeces + 75% agricultural waste, and T5)100% agricultural waste. The parameters measured were slurry production and slurry chemical compositions including N,P ,K, pH, and C/N.The result showed that T1 and T2 were better in chemical compositions(N,P,K, pH and C/N) while all treatments produce equal volume of slurry. It is suggested that local farmers use the composition of T1 and T2 when using biogas technology in supporting organic fertilizer. It is noteworthy that this first study is continued with the second one which utilize the resulting slurries of the first on Asparagus and analyse their performance during the period of August to October 2016.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
