Abstract

Pleurotus ostreatus is one of wood fungus whose easier to cultivated, because it has good adaptability to grow. The use of oil palm empty bunches (tankos) as a medium for the growth of Pleurotus ostreatus was carried out  to determine the effect of tankos as a medium on Pleurotus ostreatus yield. The experiment was conducted at the Production House of Pleurotus ostreatus Desa Cerme, Grogol, Kediri. This experiment was used non factorial Randomized Complete Block Design consisting of 5 treatments which is the ratio of tankos and sawdust for medium, there are 0%:100%; 25%:75%; 50%:50%; 75%:25%; and 100%:0%. The results showed that tankos potential as a medium for Pleurotus ostreatus, as indicated by the content of lignin, cellulose, and hemicellulose which are nutrients for growth and development fungal, the higher the composition of the tankos, the higher the nutrient content. The observations for the hood diameter, harvest interval, and wet weight were best in the composition treatment of 50% Tankos: 50% Sawdust.  Keywords: tankos, medium, fungus

Abstract

An effort to increase productivity is provision of inorganic fertilizers. Inorganic fertilizer application in longtem as found to attenuate the availability of micronutrients and to decrease soil fertility. One possibility to replace inorganic fertilizer is the use of ash derived from plants, such as wood ash. The purpose of this study was to determine the effect of wood ash on soil K availability and to optimize the dose of wood ash which can give good influence on the growth of cocoa seedlings. The experiment was conducted at the experimental station Polytechnic LPP in Wedomartani, Sleman, Yogyakarta. The design used is non factorial randomized block design with 5 treatments, which is the ratio of ash and soil 0: 1 (A1 / Control); 0.25: 1 (A2); 0.5: 1 (A3); 0.75: 1 (A4); and 1: 1 (A5). Observations of treatment effects were made on the seedling height, number of leaves, stem diameter, wet weight and dry weight. Soil analysis was conducted to determine the content of macro elements, micro elements, and pH media. The results showed that ash increases the pH of the media to alkaline range and increase the availability of P and K soil to toxic range. Giving ash reduced the availability of N and caused chlorosis on cocoa seedlings.

Abstract

Sugarcane (Saccharum officinarum L.) is a plant that propagated by vegetative, one of which is the budset system. This propagation is mostly done by farmers, but they have stocks in ordering the roots. One of the efforts to accelerate the formation of these roots can be done by using a Plant Regulator Growth (PGR). PGR from synthetic materials is widely sold in the market, but there are also natural ingredients that can function as PGR, one of which is bamboo shoot extract. This research was to know the effect of bamboo shoot extract concentration as a natural PGR on the growth of sugarcane (Saccharum officinarum L.). The experiments was conducted at the LPP Yogyakarta Polytechnic practical garden, Wedomartani, Sleman, Yogyakarta. This experiment was laid on non factorial Randomized Complete Block Design consisting of 5 treatments which is the concentration of bamboo shoot extract with a ratio of 2:1, 4:1, 6:1, 8:1 (bamboo shoot extract : water), and Control. The results showed that bamboo shoot extract with a concentration of 4:1 is the best treatment. That treatment (4:1) was produce the higher plants, number of leaves, number of tillers, stem diameter, root length, and root wet weight were better than other treatments.
