Abstract

One of the efforts to deal with this problem can be through the use of planting media and the right nutrient system. This study aims to determine the influence of the type of bark planting medium, nutrient system and interaction on the growth and yield of Honey Dew. This study uses a Factorial Group Random Design. Treatment cempedak bark planting medium with drip irrigation, cempedak bark planting medium with direct watering, sengon bark planting medium with drip irrigation, sengon bark planting medium with direct watering, pine bark planting medium with drip irrigation, and pine bark planting medium with direct watering. Research of results showed that the use of bark planting media had a significant effect on fruit length and fruit diameter. The nutrient system has a significant effect on plant height, number of leaves, stem diameter, fruit weight, fruit length, number of seeds in the fruit, moisture content and sugar content. The interaction of the type of bark planting medium with the nutrient system only had significant effect on the percentage of potential fruit falls. Cempedak bark planting media shows the best growth and yield of Honey dew. The drip irrigation nutrient application system showed the best honey dew growth and yield and the interaction of pine bark planting media type and drip irrigation system gave the best honey dew crop yield.Keywords : honey dew, sengon bark, cempedak bark, pine bark, nutrient application system.

Abstract

Groundnut (Arachis hypogaea L) is the most important commodity after soybean which has a strategic role as a national food source as a source of protein and vegetable oil. The use of inorganic fertilizers must be balanced with organic fertilizers that can help improve soil properties damaged by the use of inorganic fertilizers. The goal of this study was to ascertain how NPK dosages and palm oil liquid waste interacted to influence groundnut plant development and yield. The Randomized Group Design (RAK) is the design employed in this study. The first factor is palm oil liquid waste with a dose of L1 = 100, L2 = 200, L3 = 300 ml/plant. While the second factor is NPK with a dose of P0 = 0% (without NPK fertilizer), P1 = 25% (1 gram/plant, P2 = 50% (2 grams/plant), P3 = 100% (4 grams/plant). The parameters observed were plant height, number of leaves, flowering age, number of flowers, number of filled pods, number of empty pods, weight of filled pods, weight of empty pods, wet weight of stover, dry weight of stover, weight of 100 seeds. The best treatment is the combination of 300 ml/plant of palm liquid waste and 50% (2 grams/plant) NPK (L3P3). The best treatment is 50% NPK (2 grams/plant) (P2).

Abstract

Palm oil plantations in recent years have grown rapidly in almost all parts of Indonesia. The existence of palm oil mills has positive and negative impacts. The negative impact for the community is liquid waste, But can utilized for agricultural purpose such as by using liquid waste fertilizer from palm oil mills. Sweet Corn is one of the commodities favored by the people of Indonesia because it tastes good and sweet, and contains many vitamins. However, the productivity of Sweet Corn in Bangka Belitung Islands is decreasing. This study aims to produce optimal Sweet Corn growth, by using from palm oil mills. This study used a split plot Randomized Block Design (RBD) with 3 replications. The main plot is sweet corn variety (V) consist of, V1= Super sweet variety, V2= Bonanza variety, V3= Paragon variety, and the subplot is the interval of application of palm liquid waste (P) consist of, P0= Control, P1= Interval once every 10 days, P2= Interval once every 20 days, P3= Interval once every 30 days. The results of statistical analysis showed that different varieties of sweet corn gave a significant effect on harvest age, cob diameter, cob weight with clobber, cob weight without clobber and yield per plot. Giving different intervals gives a significant effect on stem diameter and cob diameter. Bonanza variety is the best variety in sweet corn growth and production. Once every 10 days is the best interval for sweet corn growth and production. The interaction of paragon variety and interval of 10 days give the best result for the parameter of age of female flowering in sweet corn.   Key words: Interval pemberian, Pupuk organik, Limbah cair kelapa sawit, Jagung manis
