Abstract

A study that was aimed to analyze margin and efficiency of jasmine marketing had been conducted at Labuan Village, Martapura district of Banjar Regency. The study objects covered farmers, traders, and consumers. Qualitative analyses were performed to describe marketing channels, marketing functions, and related agencies. Quantitative analyses were used to calculate marketing margin. Results of this study showed that there had been four channels of jasmine marketing. Marketing functions that were performed by marketing agencies included trading, physical and facility functions. The highest profit made was found at channel three. The most efficient marketing process was observed at channel one (farmers-consumers)

Abstract

A field experiment that was conducted at Ketanggi Village, Karangploso District of Malang Regency in May-September 2007, was aimed to study the effects of farmyard manure and NPK fertilizers on growth and yield of groundnut. Data were collected through measurements of plant height, number of branch, number of leaves, plant biomass weight, wet and dry weight of ‘polong’ number of ‘polong’, and weight of 100 dry seeds. Results of the study showed that there was no significant interaction between farmyard manure and NPK fertilizer treatments at all measured variables. Results of separate statistical analyses, however, showed that application of farmyard manure and NPK fertilizer with a rate of 20g/plot could improve growth ands yield of groundnut

Abstract

One of the methods to increase the efficiency of farming product is to the product to become durable product, for example, apple is processed to become vinegar through fermentation. The purpose of this research was to find out whether or not apple fermentation process can produce alcohol with khamir sacharomyces cereviceae, and further fermentation can form vinegar with acetobacter aceti bacteria. In addition, the special purpose of this study was to know the influence of the storage temperature and the fermentation process time on the quality of vinegar production. The results of this research hopefully could increase knowledge about apple processing to become acetic acid. Thus as the constant variable was volume of apple essence, the amount of ammonium sulfate, khamir, acetobacter aceti, time of storage, pH speed of stirrer and temperature of fermentation, where as change of variable was process time. From the research results it was known that the best quality of acetic acid was obteianed at the 62nd hour in the amount of 0.91% (room temperature) and 0.54667% (freezer temperature)
