Abstract

This research was conducted at the Laboratory of Faculty of Agriculture, University of Lancang Kuning. The study was conducted for 3 months from September to November 2015. This study is a descriptive research, where the first process is the process of making organic fertilizer derived from pineapple skin waste fermented for 1 month POC that has been taken samplenya and tested in the laboratory to determine the content of micro and macro nutrients and C-organicnya. To measure macro and micro nutrient content, the test method used was Kjeldahl for nitrogen content, while for P, K, CaO, MgO and Fe, the Atomic Absobtion spectrophometric (AAS) method was used and the C-organic content was tested by spectrophometric method. The results showed that POC of Pineapple Skin Waste contained P 23,63 ppm, K 08,25 ppm, N 01,27%, Ca 27,55 ppm, Mg 137,25 ppm, Na 79,52 ppm, Na 79, 52 ppm , Fe 1,27 ppm, Mn 28,75 ppm, Cu 0,17 ppm, Zn 0,53 ppm and C Organic 3,10%.

Abstract

This study aimed to determine the effect of rock phosphate fertilizer with various doses of the production of oil palm fresh fruit bunches. Results from this study is the final conclusion of phosphate rock fertilizer does not affect the measurement of the diameterbuah fresh, fresh fruit weight and number brondolan fall and was advised to continue observation until 6 months after treatment applications in order to look the influence of rock phosphate. Rock Phosphate Fertilizers no real effect on the diameter of oil palm fresh fruit bunches in the cultivation of oil palm trees suggested in this study a longer observation that 6 months.

Abstract

Papaya (Carica papaya L.) cultivation gets a lot of disturbances such as pests or diseases that can reduce the quality and quantity of papaya fruit. The use of vegetable insecticides is effective in controlling pests and has potential as a plant insecticide such as citronella, neem and cloves. This study aims to determine daily mortality and obtain the most effective botanical insecticides in controlling mealybug pests on papaya plants. The study consisted of two stages: (1) assessing the percentage of daily mortality, (2) the effectiveness of citronella oil, neem extract and clove oil vegetable insecticides on papaya seedlings. Daily mortality data were calculated using the daily mortality formula and data on the effectiveness of vegetable insecticides were analyzed using analysis of variance. The results showed that the highest percentage of mortality by giving citronella oil had a 24-hour daily mortality percentage and clove oil at a 48-hour daily mortality percentage. Botanical insecticides had an effect on all observation parameters, plant height, number of leaves and stem diameter, while the most effective treatment in controlling the mealybug P. marginatus treatment N1 was citronella oil with a concentration of 1 cc/500 mL.
