Abstract

This research was conducted on September 2017 – March 2018, in the greenhouse and laboratory of STIPAP Medan. This study used a factorial randomized block design with three repetitions, with total sample was 27 samples. Parameters observed were plant height, stem base diameter, leaf number, leaf area, root number, root length, root dry weight, shoot dry weight, root volume and number of stomata. The data obtained were analyzed statistically by analysis of variance (ANOVA) with Duncan's advanced test of 5%. The results showed that the di erence in the provision of water in the Main Nursery nursery a ected to the growth of oil palm seedlings significantly a ected plant height, canopy dry weight, leaf chlorophyll and root volume except stem diameter, leaf number, leaf area, number of roots, root length, weight dry root and number of stomata. Oil palm is a plant that has shallow roots (root fibers), so it is easy to experience drought stress. Water availability is one of the main limiting factors for the growth and production of oil palm plants. In the vegetative phase lack of water availability can cause damage to plant tissue, while in the generative phase can reduce the production of oil palm plants.

Abstract

Mucuna bracteata is a type of Leguminosae Cover Crop (LCC) which is widely used in Indonesian plantations. The advantage of Mucuna bracteata is that it grows fast. Based on this, a study was conducted to see the rate of difference in the number of internodes planted which could accelerate the growth and development of Mucuna bracteata. The research was carried out in the practical garden area of ​​the Medan Agricultural College of Agribusiness (STIPAP). The research was conducted from May to June 2020. This study used a non-factorial randomized block design (RBD), which consisted of 1 treatment with 4 levels, namely R0 (1 rolled segment), R1 (2 rolled sections), R2 (3 rolled humps), R3 (4 rolled humps) and with 5 repetitions. The results showed that the treatment of R2, namely 3 bundles of rolled knuckles, gave the best effect on the parameter increase in tendril length, namely 89.66 cm, the increase in the number of tendrils, namely 6.38, the increase in the number of leaves, namely 12.50 strands, the increase in the number of segments, namely 11.32 pieces, and the measurement of the root volume, namely 13.00 ml. The treatment of the number of bunded knots had a significant effect on the parameters of tendril length, number of tendrils, number of leaves, number of internodes, and volume of roots.

Abstract

Drone is an unmanned aircraft (Unmanned Aerial Vehicle), which is an electro-mechanical based system that can perform programmed missions, with the following characteristics: (i) unmanned, (ii) operating in fully or partially independent mode, (iii) ) This system is designed to be used repeatedly. The drone is equipped with a high-resolution camera that allows users to monitor a specific location from a height in real time. The use of mapping photos (Mapping Block) using drones is usually used to calculate the principal amount of oil palm trees. This research was using drone fixed wing tipe and was conducted in Tamiang Hulu District, Aceh Tamiang District Nanggroe Aceh Darussalam. This research was conducted from 25-28 August 2020. This study used a descriptive analysis method. The results of this study indicate that the time used to prepare for the use of drones is 30 minutes, for taking aerial photographs and flying time for 25 minutes, combining photos using the Agisoft Photoscane software for 45 minutes, making way points and calculating the number of trees using the Arcgis application for 5 hours, making printout data for 60 minutes, so that the total time for all work is 7 hours 40 minutes for 53.53 hectares, assuming the cost per hectare is Rp.8,583, if with a manual census the time needed is 72 hours, with average costs -average Rp. 56,374, - / ha. Conclution of this research by using drones will be more effective and efficient than manual tree census.

Abstract

This study was conducted to determine the effect of application of coconut shell biochar on planting media on the growth and uptake of leaf and soil nutrients in oil palm main nurseries. To get good and healthy seeds, soil conditioner is also needed to increase land productivity. One of the soil improvement materials is biochar. This research was conducted in the STIPAP Medan experimental garden. This research was conducted for 6 months. Starting in August 2020 - February 2021. This study used a Factorial Randomized Block Design (RAK) method consisting of 9 treatments with 4 replications, so the total sample was 36 seedlings. Parameters observed were seedling height, stem diameter, number of leaves, shoot dry weight, root dry weight and nutrient N content in leaves and soil. The data obtained were analyzed statistically by analysis of variance (ANOVA) with the F test. The results of this study indicate that the application of coconut shell biochar and compound fertilizer in oil palm nurseries can use the best combination dose of 1.8 kg of biochar and 75% compound fertilizer of the dose. The standard gave several significant and very significant effects on stem height, stem diameter, number of leaves, shoot dry weight and root dry weight. And the interaction of coconut shell biochar treatment and compound fertilizer did not significantly affect all observation parameters.

Abstract

Oil palm plants are monocotyledonous plants where there are male flowers and female flowers in one tree, the appearance of oil palm flowers is at the base of the midrib, the average time at different stages of flower development. The T-Test sex ratio test was not significantly different. The photos shown refer to the standards set by BBCH (Biologische Bundesantalt Bundessortenamt und Chemische Industrie) explaining the stages of flower and fruit development in oil palm plants. Vegetative development includes plant height, number of leaves, rachis length, petiole thickness, number of leaflets, leaflets. The research was conducted at the Indonesian Palm Oil Institute (ITSI) Medan practice garden. The time of the study starts from August 2021 to March 2022. This study aims to determine and study the stages of flowering of oil palm plants in two different varieties by observing each flowering stage that occurs in oil palm plants. The method used is descriptive with qualitative and quantitative models. The results showed that the use of different varieties gave different results on the generative and vegetative growth of oil palm plants. The photos shown refer to the BBCH (Biologische Bundensartalt Bundessortenamt und Chemische Industrie) standard of flower development stages. The results of the T-test showed that the value of sex ratio, rachis length, petiole thickness, petiole cross section (LxT), number of leaflets on one side, length and width of leaflets, leaf area gave the effect of accepting H0 (not significantly different) while the T-test -Test on plant height, number of leaf fronts and total leaf area gave the effect of rejecting H0 (significantly different).
