PENGARUH LAMA PEMANASAN BASAH DAN PERENDAMAN DALAM GIBERELIN  TERHADAP PEMATAHAN DORMANSI BENIH KELAPA SAWIT (Elaeis guineensis jacq.)

The aims of this research to determined the effect wet heating and immersion in gibberellins on breaking dormancy of oil palm seed. The treatment was arranged in factorially with two factors in the Completely Randomized Design. The first factors was wet heating which consists of five levels, (1) 20 days of heating; (2) 25 days of heating (3) 30days of heating (4) 35 days of heating (5) 40 days of heating. The second factor was the concentrations of gibberellin in four levels, (1) 0 ppm; (2) 100 ppm; (3) 200 ppm and (4) 300 ppm. Based on the results could be concluded that (1) wet heating could increased the percentage of germination, maximum growth potential, speed of germination, and time of emergence of sprouts, (2) 30 days wet heating treatment + immersion in 200 ppm giberelin was the best treatment in percentage of germination (64 % ± 1.3), maximum growth potential(70.7%±1.4), and speed of germination (29% ± 1.0 per etmal).

Abstract The use of chemical fertilizers in agriculture has caused soil degradation and is harmful to human health. Organic fertilizers made from animal waste have received worldwide attention because they are not detrimental to health or the environment. This paper describes the effect of using organic fertilizers from chicken manure on the growth of papaya plants. A completely randomized design was used in this study using two factors and three repetitions; the variations of the fertilizers given were 0, 50, 100, 150, and 200 g. This study informed that organic chicken manure had a significant effect on the growth of oil palm and papaya plants. The best growth is oil palm and papaya plants given 200 g of organic fertilizer from chicken manure.

This study was conducted in Tumpok Teungoh Village, Banda Sakti Sub-district, Lhokseumawe City, August to September 2016. This study used Completely Randomized Design with 3 replications. Two factors studied were (a) the location of the fruit on the tree where L1 = The location of the fruit on the stem and L2 = The location of the fruit on the branch. (b) treatment factor in seeds where P1 = Without pulp clearance, P2 = Pulp cleansing. The parameters observed were potential growth, germination, vigor index, growth rate and synchronization of cocoa seed growth. The result of variance analysis showed that the fruit difference treatment did not affect the observation of maximum growth potential and cocoa seed germination, but it influenced the observation of vigor index, growth rate and synchronization of cocoa seed growth. Treatment of pulp cleansing did not affect the observation of growth potential, germination, growth rate and synchronization of seed growth, but pulp cleansing treatment had an effect on observation of vigor index of cocoa seed. There was no interaction between fruit difference treatment and treatment of cocoa bean pulp cleansing of all observed parameters

Low productivity of oil palm in Ultisol need to resolve by utilizing appropriate input and efficient soil management. Utilization of organic waste materials such as oil palm empty bunches (OPEB) is one of way for that. This research was conducted in Kuantan Singingi, Riau from September 2017 to February 2018. The aim of this research is to having dose of OPEB compost and NPKMg fertilizer that can optimize the value of soil chemical characters and nutrient content in leaves. The study determined the effect of composite oil palm empty bunches with cow manure (2:1(w/w)) and NPKMg (13:6:27:4) fertilizer. The study used a completely randomized design consisting of 6 levels :{(2,25 kg NPKMg), (10 kg OPEB compost + 1,75 kg NPKMg), (20 kg OPEBcompost + 1,5 kg NPKMg), (30 kg OPEBcompost+ 1,25 kg NPKMg), (40 kg OPEBcompost + 1,00 kg NPKMg), (50 kg OPEB compost) per tree}, each treatment was repeated 3 times. Parameters measured include soil chemical characters and nutrient content in leaves. The results of study showed, aplication 50 kg per tree TKKS compost was able to increase soil pH. Aplications (2.25 kg NPKMg, 50 kg TKKS compost, 20 kg compost TKKS + 1.50 kg NPKMg and 30 kg compost TKKS + 1.25 kg NPKMg) per tree can increase base saturation. Each treatment application for fertilization has been tested, given the same effect in all soil chemical characters tested beside pH and KB, and same effect in all leaf nutrient contents tested beside Zn.Key words : Palm Oil, Compost, OilPalmEmptyBunches, NPKMg

Soaking oil palm seeds in a solution of sulfuric acid and gibberellic acid is one way to shorten the dormancy period of oil palm seeds. This study aimed to find out the optimum soaking time of oil palm seeds in sulfuric acid solution to accelerate germination, the optimum concentration of gibberellic acid for oil palm seed germination, the interaction between using sulfuric acid and gibberellic acid in accelerating the germination of oil palm seeds and the best treatment combination in all the tried treatments. The experimental design used was a completely randomized design (CRD), with a complete factorial combination with a total of 16 treatments. Each treatment was repeated 4 times, so there were 64 experimental units and each unit was planted with 5 seeds. The results of statistical analysis showed that soaking oil palm seeds in a solution of sulfuric acid and gibberellic acid had an effect on the germination of these seeds. The duration of soaking oil palm seeds for 48 hours in sulfuric acid solution constituted the optimum time for increasing the speed of germination and giving gibberellic acid at a concentration of 300 ppm still accelerated the germination of oil palm seeds and there was no interaction between the length of soaking the seeds in sulfuric acid solution and the concentration of gibberellic acid. Soaking the seeds in a solution of sulfuric acid for 48 hours and gibberellate 300 ppm was the best combination treatment to accelerate the germination of oil palm seeds.

This study aims to determine the effect and find the best composition of Kelud volcanic ash and manure to the availability and corn uptake of potassium in the Alfisols.This research is expected to provide information on the composition of volcanic ash Kelud and proper manure for agriculture. This research was conducted in the greenhouse, in the Laboratory of Ecology and Management of Crop Production, and soil chemistry laboratory of the Faculty of Agriculture, Sebelas Maret University in June 2014 - January 2015. Research using completely randomized design which consists of two factors, there are the thickness of Kelud volcanic ash which consists of four levels A0 (0 cm), A1 (2 cm), A2 (4 cm), and A3 (6 cm) and the dose of manure were P0 (0 ton/ha), P1 (2,5 ton/ha), and P2 (5 ton/ha). Each combination treatment was repeated 3 times. The data were then analyzed using the F test and continued with Duncan Multiple Range Test Test (DMRT) level of 95%. The results showed that the interaction between the two treatments were no significant different. Availability Potassium gradually decreased with an increase in the dose of volcanic ash Kelud, allegedly because of the low value of the total potassium Kelud volcanic ash. The results of measurements of plant potassium uptake increased with increasing dose Kelud volcanic ash and manure.</p>
