Abstract

ABSTRACT The Utilization of Oil Palm Empty Bunches and Nitrogen Fertilizer as Substitution of Top Soil on Growth of Oil Palm Seedling (Elaeis guineensis Jacq.) in Pre Nursery Palm oil (Elaeis guineensis Jacq.) is the leading commodity in Indonesia, Indonesia can produce 23.900 ton or 40,27% of the total world production palm oil. To increase the production of palm oil so it’s necessary to the expansion of oil palm plantations. Media used for oil palm seedling is top soil, difficulty to get top soil it’s because it’s used continuously or eroded due to erosion so the availability of top soil is limited. Therefore, needed alternative to substitusion of top soil as a media of oil palm seedling. The purpose of this research was to know potential of compost oil palm empty bunches (TTKS) and nitrogen fertilizer as substitution of top soil on growth of oil palm seedling in pre nursery. This research used randomized complete block design with 2 factors. The first factors is media with top soil + sub soil + sand (3:1:1), TKKS compost + sub soil + sand 3:1:1, 1:3:1, 2:2:1, 2:1:2, 1:2:2 and the second factors is doses nitrogen fertilizer (urea 46%) with 0 g urea/pot, 2 g urea/pot and 4 gurea/pot.The research result showed that media TKKS compost + sub soil + sand 2:2:1 and 3:1:1 can substitution top soil because it has a value that is greater than or equal to the observed variable with controls. The application of nitrogen 4 gurea/seed showed the maximal growth of oil palm seedling in pre nursery.  The interaction of the both treatment just significant to plant height 4 and 12 weeks after planting, leaf area 4 weeks, steam diameter and leaf  number 8 weeks,  fresh weight of  crown 12 weeks. Composition of TKKS compost + sub soil + sand 3:1:1 + 4 g urea/pot is the best composition as a substitution of top soil because the value of  parameters plant height, leaf number, total chorophyll, fresh weight of crown, fresh weight total and dry weight total are greater than or equal to top soil.

Abstract

Utilization of Insect Pathogen (Beauveria bassiana Bals.) to Control the Suction Pest of Cocoa (Helopeltis spp.) in Gadungan Village,The District of East Selemadeg, Tabanan RegencyCultivation of cocoa has the potential to improve the economy of farmers. However, cocoa production has decreased due to Helopeltis spp. The control of Helopeltis spp. still use synthetic chemical pesticides that are harmful to the health of farmers, consumers and environmental pollution. Therefore, it needs to be done by eco-friendly control using Beauveria bassiana which is reported to be able to control some insect pests such as Helopeltis spp. Utilization of B. bassiana is usually in the form of formulations. The research was conducted to determine the quality formulations and efficacy of B. bassiana against Helopeltis spp. obtained from Dinas Perkebunan Provinsi Bali. The research method using randomized block design with 5 treatments, 5 replications and the treatment using concentration formulation 20 grams, 15 grams, 10 grams, 5 grams to dissolve in one liter of water and the control just using water. The observed variable is the number of former suction on fruit. The identification results showed the tested formulations made from active B. bassiana which is characterized by colonies are white, round-shape and the spore structure is like grapes with a good quality because it has spore density 1,06x107 spore/ ml. B. bassiana is quite effective to infect Helopeltis spp. because it just need 4 days to kill Helopeltis spp. The test results showed the concentration of 20 grams formulation is the best concentration with the fewest number of former suction on fruit.
