Abstract

This study aims to determine the price volatility in producer of red pepper and cayenne pepper in West Java Province. The data used in this research was secondary data focusing on monthly price statistics of red pepper and cayenne pepper producer in West Java Province from 2008 to 2015. The method used in this research was ARCH/GARCH method with best model determination. Based on the research, it was found that the best model for the price of red pepper in producer was GARCH (1,1) with the volatility value of 0,96. It means that volatility of price of red pepper in producer level was influenced by the increase and fluctuations on producer price of red pepper one month before. The best model for the price of the cayenne pepper producer was ARCH (1) with the volatility value of 0,52. It means that price volatility of cayenne pepper in producer level was also influenced by fluctuations producer price of cayenne pepper one month before. The value of volatility price of red pepper in West Java Province is closed to one, so it can be categorized of high volatility.

Abstract

Pandeglang district is the largest soybean producer region in Banten province. Since the last four years, Pandeglang Regency has decreased land area and production. However, the amount of soybean productivity has increased. The ability of farmers to manage and allocate various inputs used in soybean farming affects the production and productivity of soybean and can give an idea of the level of efficiency achieved by farmers. So it is necessary to research whether the application or use of inputs in the process of soybean production has been at technically efficient level or not. Based on these conditions, in this study aims to: know the level of technical efficiency in soybean farming in Pandeglang regency. The basic method used in this research is descriptive method and the location of research is determined intentionally or purposive sampling. Sample selection for soybean farmer respondents was done by simple random sampling method of 77 soybean farmers. The result of the research shows that production factors that significantly affecting soybean production in Pandeglang are wide, fertilizer and insecticide. The average value of farmers' technical efficiency is 0.864. This figure indicates that the average farmers of respondents have reached technical efficiency in soybean production in the research area. the technical efficiency value of the stochastic function with the lowest value 0.6314 and the highest value 0.9599. Factors affecting technical inefficiency are age and training. However, these factors have a positive effect, meaning that both increase the level of technical inefficiency of soybean farming.

Abstract

The research objectives are to (i) analyze the effects of restoring the growth medium (rhizosphere) toward the production of stevia leaves and (ii) analyze the financial likelihood to restore the growth medium (rhizosphere). The data necessary to answer objective 1 and 2 was retrieved from field research utilizing plot research method along with Complete Randomized Group Design (CRD) comprised of 15 x 2 executions and 3 replications. The plot size used was 2m x 0,6m (1,2m2). Research shows that rhizosphere restoration is able to increase the production of dry stevia leaves. The effort to restore rhizosphere can increase dry stevia leaf production. Financial likelihood analysis of rhizosphere restoration shows that B/C ratio is greater than one, NPV is greater than zero, IRR is quite large at 20%, Unit BEP and Price BEP was exceeded, showing that rhizosphere restoration is financially beneficial. However is still sensitive toward changes of benefit and cost. This research suggests that the increase of dry stevia leaf production should be increased even higher.
