Abstract

Previous research has found a new type of herbicide made from fermented coconut water as the main raw material, containing organic materials, microorganisms, and is environmentally friendly. A series of tests need to be done to see its effectiveness. This study aims to determine the best formulation of herbicide in controlling weeds on land weeds and aquatic weeds in multiple locations. The experiment used a randomized block design, consisting of nine treatments of herbicide formulation (Unihaz) with three replications. The treatments were Unihaz 1, Unihaz 2, Unihaz 3, Unihaz 4, Unihaz 5, Unihaz 6, Unihaz 7, Unihaz 8 (glyphosate 2 kg ha-1) and Unihaz 9 (fermented coconut water). The results of the study concluded that the Unihaz 7 formulation was effective in controlling weeds both in dryland (land weeds) and in wetlands (water weeds) at various altitudes, and could control weeds above 90%. The herbicide formulation of Unihaz 7 was better at controlling weeds in paddy fields than the use of glyphosate at a dose of 2000 g ha-1

Abstract

This study was aimed to study whether jengkol peel extract could suppress the growth of weed of Echinochloa cuss-galli, and the dose of it that effectively suppress the E. cuss-galli. This research was conducted in Teluk Segara sub district, Bengkulu from Desember 2012 to February 2013. The experimental design used was completely randomized with five replications. Jengkol extract dose treatmen were 0 g (as a control), 100 g, 200 g, 300 g, 400 g, 500 g extract each 250 ml of water. The research concluded that jengkol ekstract affect the growth of E. cuss-galli. Jengkol extract could suppress the growth of E. cuss-galli. The higher dose of extract caused the lower the growth of weeds E. cuss-galli.

Abstract

This experiment aims to determine the effect of the herbicide Unihaz formulation on 30 types of weeds that are dominant in agricultural land. The target weeds consist of 10 types of grass weeds, 10 types of nut weeds and 10 types of broadleaf weeds. The tested weeds were sprayed with a herbicide of Unihaz formulation at a dose of 50 l / ha. The results of the study concluded that the herbicide of formulation Unihaz was effective in controlling the 10 weeds of the types of grass, namely Paspalum cunjugatum, Ischaemum timorence, Chrisopogon aciculatus, Brachiaria pospoloides, Echinochloa crus-galli, Imperata cylindrica, Axonopus compressus, Ischaemum globosa, and Cyrtococum oxyphyum. This herbicide was also effective in controlling the 10 weeds of the nut species, namely Cyperus brevifolius, Cyperus trachysanfos, Fimbristylis globulosa, Scleria sumatrensis, Cyperus aromaticus, Cyperus diformis, Scirpus mucronatus, Rhynchospora crystilis, Cyperus digitarius, and Fimbristylis malaceae. The herbicide of formulation Unihaz effectively controls eight types of broadleaf weeds, namely Urena lobota, Helyotis verticilata, Crassocephalum crapidiodes, Emilia sonchifolia, Asystasia intrusa, Mikania cordata, Hyptis suaveolens, and Borreria alata, and was not very effective in controlling the weeds Clidemia hirta, and Melastoma malabatricum.

Abstract

This study aims to determine the effect of concentrations and doses of glyphosate plus fermentation of coconut water weed in oil palm plantations that have not produced. The experiment used a randomized block design arranged in factorial. The first factor is the concentration of herbicide combination (H) consisting of: H1 = concentration of glyphosate + 2 ml to 200 ml coconut water fermented, H2 = 4 ml concentration of glyphosate + 100 ml coconut water fermented. The second factor is the dose given (D), namely: D1 = 250 l / ha, D2 = 500 l / ha and D3 = 750 l / ha. Each treatment was repeated 3 times. The studyconcluded: (a) type of weed obtained in oil palm plantations are 19 types. Weeds are predominantly Ischaemum muticum (grasses) (28.6%), followed by weeds Scleria sumatranensis (teki) (24.7%), Tetrasera indica (broad leaves) (10.6%), Leersia hexandra (grasses ) (7.2%) and Imperata cylindrica (grasses) (6.4%). Five important weeds have already mastered a land area of 77.5%, (b) the herbicide glyphosate at a concentration of 2 ml of water mixed with 200 ml per liter of fermentation of coconut water and glyphosate with a concentration of 4 ml was mixed with 100 ml of fermented coconut water is able to kill weeds in plantation palm immature, (c) Dosing liquid spray as much as 250 l / ha, 500 l / ha and 750 l / ha was able to kill weeds in oil palm plantations immature, (d) there is no interaction between the concentration and amount of fluids given in control weeds in immature oil palm plantations.Keywords: Glyphosate, water coconut fermented, weeds,concentration, dose, palmplantation

Abstract

This study aims to determine the toxicity of the formulated herbicide concentration to non-target organisms (non-target) earthworms. The study was conducted from April to July 2021. The design used was a completely randomized design (CRD) with nine (9) herbicide concentrations (K) treatments, namely: K0 = control, K1 = 200 ppm concentration (0.2 ml/l water ), K2 = concentration of 400 ppm (0.4 ml/ l of water), K3 = concentration of 600 ppm (0.6 ml/ l of water), K4 = concentration of 800 ppm (0.8 ml/ l of water), K5 = concentration 1000 ppm (1.0 ml/ l of water), K6 = concentration of 1200 ppm (1.2 ml/ l of water), K7 = concentration of 1400 ppm (1.4 ml/ l of water), K8 = concentration of 1600 ppm (1, 6 ml/l water). Each treatment was repeated 3 times. The observed variables were mortality concentration 50 (LC50) for 96 hours, survival rate, mortality percentage and worm weight. This study concluded that the mortality concentration of 50 (LC50) for 96 hours from the formulated herbicide against earthworms was 600 ppm, while the 100% mortality occurred at the herbicide concentration of 1400 ppm. The lowest survival rate was found at a concentration of 1400 ppm, where at that concentration all the test worms died. Meanwhile, the highest survival rate after the herbicide was 200 ppm where the worm mortality was 20%. The higher the concentration of herbicide formulation given to earthworms, the higher the mortality rate and decrease in body weight.

Abstract

Many sources of raw materials which allegedly can enrich the nutrient content in the organic fertilizer. The weakness of organic fertilizer for this is the low level of nutrients contained in them.This study aims to determine the nutrient content contained in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material.This study aims to determine the nutrient content in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material. The experiment used a completely randomized design with raw materials as treatments, Livestock Waste Rabbit (LTK), Cow Manure (PKS) and Abu Straw Rice (AJP). Such treatment: B1 = LTK; B2 = LTK: PKS = 2: 1; B3 = LTK: AJP = 3: 1; B4 = LTK: PKS: AJP = 6: 2: 1; B5 = LTK: PKS: AJP = 5: 2: 1; B6 = LTK: PKS: AJP = 4: 2: 1; B7 = LTK: PKS: AJP = 3: 2: 1; B8 = LTK: PKS: AJP = 2: 2: 1; B9 = LTK: PKS: AJP = 1: 2: 1. The research concluded (a) Organic fertilizers are made from various materials raw has fulfilled SNI 19-7030-2004 about the specifications of Organic Waste Compost. (B) A combination of organic fertilizer raw materials significantly affect the nutrient content of manure. (C) Organic fertilizers expectations are: (a) Raw materials of animal wastes rabbit (LTK), (b) LTK: PKS: AJP = 6: 2: 1, (c) LTK: PKS: AJP = 2: 2: 1 and (d) LTK: PKS: AJP = 1: 2: 1.
