Abstract

Weeds on oil palm plantations can also be the host of Basal Stem Rot caused by Ganoderma. This study aims to identify and analyze of weed vegetation using visual estimation and squares method as Ganoderma presence marker on oil palm plantations. This research was conducted in block 17, 16, and 6 of VII afdeling, Rambutan Estate in Serdang Bedagai Regency on December 2017 to March 2018. This research used survey method with visual estimation and squares. The data used is absolute density, relative density, absolute frequency, relative frequency, important value indeks, Summed Dominance Ratio (SDR) and dry weight. Data analysis using IBM SPSS Statistics 20 software. The results showed that different weed species between oil palm was infected and uninfected by Ganoderma with visual estimation method is Cyclosorus aridus (14.78%) where as with squares method are Cyperus rotundus (10.60%), and Stenochlaena palustris (7.76%) with temperature range 28.67 to 30.80oC and moisture amount 60.67 to 77.33%.

Abstract

The presence of Eleusine indica from oil palm plantations in Serdang Bedagai Regency has never been overall reported glyphosate-resistant. This study aims to distribution mapping and resistance classification of E. indica population to glyphosate herbicide of oil palm plantations in Serdang Bedagai Regency. This research was conducted on Weed Research Center Land in Faculty of Agriculture, Universitas Sumatera Utara in October 2016 to August 2017. This research used glyphosate herbicide with the recommended dose at 720 g ai ha-1 and three replications. Population ESU0 (from Politeknik Negeri Medan Ball Field) as a comparison. Data analysis using IBM SPSS Statistics 20 software. The results showed there E. indica population classified as glyphosate-resistant amount 89.36% (42 population), classified as glyphosate-resistant moderate amount 10,64% (5 population) and there is no population glyphosate-susceptible on oil palm plantations in Serdang Bedagai Regency of recommended dose at 720 g ai ha-1.

Abstract

Abstract: Eleusine indica population from several estates in Padang Lawas and Tapanuli Selatan Regency, Sumatera Utara Indonesia has never been reported to be resistant to glyphosate herbicide. This study aims at distribution mapping and resistance classification of Eleusine indica glyphosate-resistant populations from several estates in Padang Lawas and Tapanuli Selatan Regency, Sumatera Utara. This research was conducted at Weed Research Center of the Faculty of Agriculture, Universitas Sumatera Utara from October 2016 to August 2017. This research used glyphosate at the recommended rate of 720 g ai ha-1 and three replications. Population ESU0 (from Politeknik Negeri Medan Ball Field) as a comparison. Data analysis using t-test at the level of 5% with IBM SPSS Statistics 20 software. The results showed 22 populations in Padang Lawas Regency have 8 populations classified as glyphosate-resistant (36.36%), 8 populations classified as developed-resistant (36.36%), and 6 populations classified as glyphosate-susceptible (27.27%). While from 6 populations in Tapanuli Selatan Regency have 5 populations classified as glyphosate-resistant (83.33%), 1 populations classified as developed-resistant (16.67%), and 0 populations classified as glyphosate-susceptible (0%). Keywords: glyphosate, goosegrass, oil palm plantation, resistance.

Abstract

Abstract The aim of this research was to improve the quality of liquid waste water by looked at the role of test plants (warter hyacinth, water jasmine and apu wood)by phytoremediation process in reducing pollutant level. This research was conducted at Rumah Kaca Faculty of Agriculture University of Sumatera Utara Medan from July 2016 to April 2017.This research was used factorial randomized block design with two factors. The first factor was tofu waste with three levels; L0 (no waste) as control , L1(25%) and L2 (50%). The second factor was plant species with four levels were T0 (no plant as control), T1 (water hyacinth), T2 (jasmine water) and T3 (apu wood). The parameters observed were BOD (mg / L), COD (mg / L), TSS (mg / L), NH3N (mg / L), pH, waste colours, odor waste and dry weight of plans (grams).The results showed that the three test plants could be used for phytoremediation process, tofu waste, 25% waste concentration as the best apu wood in reducing the pollutant level of tofu waste.Keywords: tofu liquid waste, aquatic plants, phytoremediation, contaminants
