Lettuce (Lactuca sativa L.) is vegetables with high nutrient content and interest more people, meanwhile producing optimum, yet, therefore, need hydroponic substrate to increase productivity. The orange wood fiber is a waste produced by palm industry manufacturer. The waste of Arenga wood fibers has not used maximum yet, so if it’s piled up will be affects the ecosystem in around. We need to utilize the waste of Arenga wood fiber to be a substrate hydroponic. The aim of this research is to know the maximum of Arenga wood fiber composition in several sizes which is combined with the sands. It’s for increasing the growth and lettuce yield. The method of this research is completely randomized design with two factorials. They are the Arenga wood fiber composition with sand and size of Arenga wood fiber. The main variable of observation is root length, wide of leaves, and fresh weight of lettuce. The result of observation showed that the Arenga wood fiber composition and the sand composition for cultivation lettuce consist of 25% of Arenga wood fiber and 75% (1:3) of various size of sand. The highest root was 12.6 cm and it produced wide of leaves was 1602.3 cm2 and increased the fresh plants until 53.7 g.

Soybean is one of the commodity with high market demand. Soybean production process is limited by the lack of land. One of the efforts to improve the usefullness of land and production of soybean is an intercropping method between soybean and corn. Intercropping that over using chemical fertilizers have impact negatively on the land. Therefore, utilization of organic fertilizer to reduce the chemical fertilizer is necessary to prevent the damage of the land. This study aimed to examine the utilization of organic fertilizer to replace a part of chemical fertilizer. This study was conducted at the Center for Dryland Research Faculty of Agriculture, University of Sebelas Maret Surakarta, Jumantono, Karanganyar started on February until May 2013. The experiment was conducted using Randomized Complete Block Design (RCBD) with one factor fertilization consists of 6 levels, one control and two comparators monoculture. The results showed that application of organic fertilizer 800 kg ha-1, Urea 125 kg ha-1, SP-36 83.33 kg ha-1 and KCl 83.33 kg ha-1 with the highest yield for soybean 1.52 tons ha-1 and corn 1.25 tons ha-1 is optimal balance dosage of organic and inorganic fertilizers to soybean-corn intercropping. The treatment did not significantly different with inorganic fertilizer intercropping experiment. The research treatment showed that N, P and K fertilizer can’t be reduce by organic fertilizers.

Cylas formicarius is the main pest of sweet potatoes especially in storage. Damage from the pest attacks can reduce yields up to 97% and even minor damage causes sweet potatoes cannot be consumed because they taste bitter and toxic. Warehouse pest control such as C. formicarius is generally carried out by fumigation. Dry ice is a solid CO₂ that can be used as a fumigant to control warehouse pests. This study aims to determine the application of dry ice as fumigant and different storage places for C. formicaius in sweet potatoes. The variables observed C. formicarius population and mortality, weight loss, decrease in water content, level of damage to sweet potatoes and taste testing. The results showed that the population of C. formicarius in control higher than the other treatments, in the storage area in the population space C. formicarius is higher than in dark storage. Mortality in the treatment of giving dry ice reached 100% at the dose of 5g, 10g and 15g. Weight reduction and decrease in water content in sweet potatoes correlate with each other where in the control treatment changes in weight and water content are highest compared to other treatments. Storage places have no effect on weight loss and loss of water content in sweet potatoes. Taste of sweet potatoes before and after the shelf life with the dry ice application has not changed.
