The aim of the research was to determine the shelf life of white oyster mushroom flour in polyethylene plastic packaging with the Arrhenius method. The study was arranged descriptively with two replications. White oyster mushroom flour was stored at three storage temperature conditions, i.e. 30oC, 40oC and 50o C in polyethylene plastic packaging with a thickness of 0.03 mm and stored for one month (28 days). Observations were made on water content, levels of free fatty acids, protein content, flavour and color of white oyster mushroom flour every once a week i.e. on days 0, 7, 14, 21 and 28. The data obtained were used to determine the shelf life of white oyster mushroom flour using acceleration (accelerated storage) method with Arrhenius equation model using Microsoft Excel software. The results showed that the shelf life of white oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm using the Arrhenius method was set at a temperature of 30o C based on the parameters of the zero reaction protein content, which was 130.67 days (4.3 months). White oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm during storage temperature of 30o C, 40o C, and 50o C tends to decrease protein content, color and aroma, but experience an increase in free fatty acid levels. White oyster mushroom flour in polyethylene plastic packaging at 30o C tends to increase in water content during storage, and decreased water content at 40o C and 50o C.

Profitable crop production starts with a weed control program that includes pre-emergence herbicides to deliver long-lasting, residual weed control. Pre-emergence herbicides are applied to prevent the germination of weed seeds. The study was conducted to determine the effect of acetic acid as a pre-emergence herbicide on maize germination. Pots experiment was conducted on August until September 2012. The experimental design used was Completely Randomized Design (CRD) single factor in four replicates. The application of pre-emergence acetic acid at several concentration, i.e. control (no acetic acid) 0%, 10% acetic acid and 20% acetic acid. The result showed that the pre-emergence aplication at 10% and 20% of the glacial acetic acid solution lowered pH were 5,12 and 5,43 respectively at one week after application, so that inhibited maize germination. No shoots and roots were grew. This was due to the increase of electrical conductivity (EC) or electrolyte leakage caused by the high permeability of the damaged membrane of seed. The EC of control treatment was 11?S/cm g, compared to 10 and 20% treatment of acetic acid were 36 ?S / cm g and 55 ?S / cm g EC respectively. Increasing concentration of acetic acid caused the higher of protein content leaked, i.e. 7,95%, 7,32% and 7,03% respectively for without acetic acid treatment, 10% and 20% acetic acid. Acetic acid also inhibited respiration rate of maize seed, where the higher concentration of acetic acid produced the lower respiration rate, i.e. 31.63 mg/g/hour, 12.38 mg/g/hour and 2,75 mg/g/hour respectively for without acetic acid treatment, 10% and 20% acetic acid.

Isoprophylamine glyphosate, a common herbicide, is widely used as a sugarcane ripener to hasten maturation and to increase sugar yield in many countries. The ripener also alter the physiology of sugarcane that might consequently affect the development of the sugarcane shoot borer, Scirpophaga nivella intacta Snell (Lepidoptera: Pyralidae). This research studied the effect of isoprophylamine glyphosate on the intensity of S. nivella intacta attacks on several cultivars of sugarcane. Results of the experiment showed that varieties of sugarcanes responded differently after application of isoprophylamine glyphosate. The percentages of damaged nodes by S. nivella intacta were higher following the application of the ripener on GM 21 and RGM 97-10167 cultivars. Conversely, the damage nodes were lower on RGM 97-8752 and RGM 97-10120 at 20-30 days after the application of the ripener. Out of four tested cultivars, GM 21 was in general the most susceptible to the attacks of the sugarcane shoot borer. On the other side, there was an indication that cultivar RGM 97-10120 applied with isoprophylamine glyphosate had the lowest damage level by S. nivella intacta. The cultivar could be further investigated to study wether it has the potential as a better cultivar against S. nivella intacta when isoprophylamine glyphosate is applied as the cane ripener.

Microfinance Institutions (LKM-A) is a venture capital under the auspices gapoktan. LKM-A growing and evolving through the Rural Agribusiness Development Program (PUAP) with facilitation fund capital gain Rp. 100 million per gapoktan which began in 2008 and continued until 2013. LKM-A were grown in 2008 and 2009 has been developed with venture capital indicators (asset) is over Rp. 150 million. The capital rent to farmers to develop agricultural businesses, one of which corn business. This paper aims to study the expression of the results to identify maize technology adoption rates in the region work Gapoktan/LKM-A in the maize production centers like Limapuluh Kota and Tanah Datar district. Survey conducted in 2012 by taking a sample of 2 Gapoktan per district with LKM-A asset criteria over Rp. 150 million and has been operating 3-4 years. Sample farmers in each region gapoktan 30 people selected randomly, consisting of 15 farmers member of LKM-A and 15 farmers not a member of LKM-A. The data were analyzed by farm analysis and comperative analysis before and after the LKM-A. The result showed that after the LKM-A, maize technology adoption by farmers of members increased compared to before there LKM-A. Before there LKM-A. majority of farmers in Limapuluh Kota District has adopted several major technologies such as (i) seed labeled 70%, (ii) 90.0% of hybrid, (iii) site-specific fertilization 36.7%. Once there LKM-A. turns the main technology adoption increases, respectively, to 100.0%, 100.0% and 90.0%. Adoption of maize technology before there LKM-A. in Tanah Datar, namely (i) the user seed labeled 63.3%, (ii) hybrid 73.3% and (iii) site-specific fertilization 30.0%, and after LKM-A. increased adoption row to be 90.0%, 90.0% and 70.0%. Other technology components also changed for the better. Technology adoption by members LKM-A is also more than the farmers are not members at the same time. Technology improvements to increase corn yields and farm profits and additional economically viable investment for technological improvements by indicators in Limapuluh Kota district MBCR = 2.72 and 1.76 in Tanah Datar district. Conclusion, that the dissemination of the technology needs to be followed by the provision of capital resources in conditions of available technology, is able to accelerate the adoption of technology. Suggested to the stakeholders that are easily accessible sources of capital such as small farmers LKM-A. needs to be developed in rural areas, in order to support the acceleration of adoption of technological innovations and development of agribusiness at farmer level..
