PERLAKUAN BENIH DAN PEMUPUKAN TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L.) TSH 858
Get PDFAbstractThe study aims to evaluate the growth response of cocoa seedlings by stripping the pulp and seed husks in cocoa and Bayfolan fertilizer. The design used was factorial randomized block design with two factors were studied, namely: Seed Treatment Factor (K) consists of three levels, ie K1 = stripping lime pulp with water immersion, K2 = stripping pulp by rubbing ashes, K3 = partial stripping of the epidermis, and the provision of fertilizer Bayfolan factor (B) is divided into three levels, namely B1 = 2 ml / liter of water, B2 = 3 ml / liter of water, and B3 = 4 ml / liter of water. While the parameters measured were plant height, leaf number, stem diameter, leaf area, wet weight and wet weight on the bottom. The results showed that seed treatment showed a marked influence on plant height parameters ages 4, 6, 8 and 10 weeks after moving planting (MSPT), the number of leaf age of 4, 6 and 8 MSPT, and stem diameter MSPT age 8, but did not differ parameter significant at age 10 MSPT leaf number, stem diameter ages 4, 6 and 10 MSPT, leaf area, as well as wet weight. While the treatment of fertilizer Bayfolan showed different effects are not real at all parameter above observations. In the interaction shows a significantly different effect on the parameters of high-cocoa seedlings MSPT age 10, but not significant different in other observational parameters.Keywords: cocoa seedling, growth response,bayfolan, Theobroma cacao L

EVAPORATIVE COOLING TECHNOLOGY TO PROLONG SHELF LIFE STORAGE OF FRESH FRUITS AND VEGETABLE
Get PDFEvaporative cooling technology could have used to phostharvest handling fresh fruits and vegetables. This piper explain about; the principle cooling, classification and type of evaporative cooler have used for prolongs shelf life of fresh fruits and vegetables, a design process of evaporative cooler. Main function of evaporative cooler operation was attained to drop temperature and increased relative humidity of storage room cooling. This condition could minimized destroyed rate of material and prolong shelf life as while as down activity enzymatic and respiration. The increasing relative humidity could retarded water losses and gas ethylene activity and production. Handling and low temperature storage was physical method available to controle losses of pascapanen products. An applications of low cost storage system was principle of evaporative cooling in storage of fruits and vegetable. Evaporative cooling as physical fenomenon where moisture evaporate at wet material surface to ambient atmosfer interface it other, so moist material temperature was drop namely cooling process. Dry bulb temperature and wet bulb temperature difference of air in let and out let system was result of evaporative cooling did. Evaporative cooler designed was system of componens namely shielve and room cooling (cabinet), cooling fan, and cooling pad.Key word: evaporative cooling, cooling pad, prolong shelf life storage fruits and vegetable
