Abstract

Research about test of several varieties of rice plant (Oryza sativa L.) against pest snail (Pomaceae canaliculata Lamarck) (Mollusks; Ampullariidae) has been completed on the grounds of rice farmers in the Village of Limau Manis Subdistrict Pauh Padang of West Sumatera from December 2011 until May 2012. The aim of this research is to get varieties are resistant to pest snail. This study use Random Design Group (RAK) with eight and three treatment groups. Its treatment is the most common varieties planted in West Sumatera that is IR 66, Cisokan, IR 42, Kuriek Kusuik, Batang Piaman, Anak Daro, Caredek Merah, and Junjuang. Experimental units of rice plant field with the size of the map 1 x 1 m that contains 25 clump rice crops and given six tail snail in piloting. The parameter is the percentage of attacks observed snail, snail intensity of attack and production. Data analyzed by fingerprint variety and continued with Duncan’s New Multipele Range Test (DNMRT) on standard 5%. The result showed that all varieties are tested there is no that is resistant to pest snail attacks, but varieties Junjuang and Kuriek kusuik have more resisting power than with other varieties that are tested. Kata Kunci: varietas padi, Oryza sativa, Pomaceae canaliculata

Abstract

The research aimed to know about the level of fertility and sold price of TBC to the productivity and income of farmer effort palm field in Labuhanbatu regency. The research was done in Labuhanbatu regerency taking of sample by used stratified random sampling as many as 30 estate with extensive gardens ranging from 0,5 ha up to 10 ha and the age of its vegetation varies, i.e.ranging from 2,5 years to 18 years. Data was analized by multiple regression test, F-test and t-test againts the influence of the independent variable agains. The results showed that simultaneouly fertilizer urea, SP-36, mop and kiserit real effect againts oil palm productivity. Partially, fertilizer urea, mop and kiserit real effect againts the production of palm oil, but fertilizer sp-36 effect is not real agains oil palm productivity, the selling price of oil palsm TBS connecting unreal with in come of farmer oil palm.

Abstract

Waste banana peels are not experiencing good management would cause environmental pollution. Sewage still contains high water content and contains organic materials in the form of carbohydrates, proteins, and fats. One of the ways that can be done to manage the industrial waste is to turn it into liquid compost (organic liquid fertilizer) fertilizer because liquid organic more quickly seeped into the ground and was quickly utilized directly by plants, and do not damage the soil and plants. This research aims to produce liquid organic fertilizer made of waste banana peels and Mucuna bracteata and know response granting POC banana peels and Mucuna bracteata against red spinach plant growth (Amaranthus tricolor L.). The research design used was randomized factorial (RAK) group with 1 factors and five levels of treatment: C0: 0 ml/plant, C1: 20 mL/plant, C2: 40 mL/plant, C3: 60 mL/plant, C4: 80 ml/plant, and continued with the test Duncan's Multiple Range tests. The parameters observed were higher plants (cm), number of leaves (strands), diameter clump (cm). The grant of a liquid organic fertilizer (POC) waste banana peels and Mucuna bracteata influential real high against the plant, number of leaves, and the diameter of the clump. Keywords: Waste banana peels, liquid organic fertilizers, growth of red spinach

Abstract

One of the important pests attacking coconut palm is Ulat Pemakan Daun Kelapa Sawit (UPDKS) like the Caterpillar. The management of habitat can be done with clean cultivation practices or cultivation use nuts cover soil (cover crop) to increase natural enemies. The research was carried out in April until July 2017. The purpose of this study was to know the abundance of natural enemies population Caterpillar fire contained in research. The location of the research consists of a private plantation with a cover crop and land communities without a cover crop. Observations of the Caterpillar's fire done every week, from first week to third week. The observation is done by swiping pitfall trap method and net. Each block palm oil taken 5 plot used to sweep net and each plot placed 2 pitfall trap. The abundance of natural enemies population level Caterpillar fires on plantation with a cover crop of 137 individuals. The community's land without a cover crop of 107 individuals. Natural enemies was found in the predator type of land cover crop as much as 88% and natural enemies of type parasitoid as much as 12%. Predator type natural enemies present on the land without a cover crop as much as 99% and parasitoid type of natural enemies as much as 1%. Keywords: caterpillar, natural enemies, palm oil, parasitoid, predator

Abstract

Endophytic fungi are a group of fungi whose part or whole life is in living plant tissue and usually does not harm the host. Endophytic fungi generally produce secondary metabolites that have beneficial biological activities such as anti-cancer compounds, antifungi or antibacterials. Control of plant diseases caused by Rigidoporus microporus and Ganoderma boninense can be done by using biological agents, namely by using endophytic fungi. This fungus has metabolite compounds that can inhibit the growth of Rigidoporus microporus and Ganoderma boninense. This study aims to determine what content is found in endophytic mushroom extracts isolated from rubber plants (Hevea brasiliensis). Endophytic fungi are extracted by maceration using methanol and ethyl acetate solvents. The extract was tested for antifungal activity using diffusion method. The content of secondary metabolites was tested by phytochemical test. The results of endophytic fungal extraction with methanol and ethyl acetate solvents resulted in antifungal activity with inhibitory zones in a row namely WL01: 2.19 and 2.15 mm Fungi Isolates on Ganoderma boninense while 3.09 mm WL02 against Rigidoporus microporus Based on the phytochemical test results, endophytic fungal extract with methanol and ethyl acetate solvents showed the presence of alkaloid, flavonoid, phenol and saponin. Keywords: endofit, fungi, hevea, secondary metabolites

Abstract

Provision of Rice Husk Ash and Rice Straw for Growth of Sweet Corn (Zea Mays L) in Ultisol Land in Rantau Selatan District Labuhan Batu District aims to determine the effect of various types of rice husk ash and rice straw for growth and nutrient uptake of Sweet Corn experimental methods. The method used in this study was compiled in a factorial randomized block design consisting of 2 factors with 3 replications. Treatment I: Giving rice husk ash (M) with 4 dose levels (g / 5 kg BTKO), namely: M0 (0), M1 (10 ), M2 (20) and M3 (30) and Treatment II: Giving rice straw (K) compost with 4 dose levels (g / 5 kg BTKO), namely: K0 (0), K1 (25), K2 (50), K3 (75). The data obtained were statistically analyzed based on analysis of variance on each observed variable that was measured and tested further for real treatment using the Duncan Multiple Range Test (DMRT) at the 5% level. The parameters measured consist of. Plant height (cm), Plant Dry Weight, Plant U uptake, Plant U Uptake. The results of this study indicate that the administration of rice straw compost has a significant effect in increasing plant height, plant dry weight, N uptake and P uptake while rice husk ash has a significant effect in increasing plant N uptake but has no significant effect in increasing plant height, plant dry weight and P uptake of plants. Keywords: husk ash, rice straw, growth, nutrient uptake, corn, Rantau selatan

The research was conducted in Dusun VI of Pangkatan Sub-district of Labuhanbatu Regency.The design of Randomized Block Design (RAK) Factorial with 2 factors studied was the factor of Kandang Lembu fertilizer (L) and ZPT Atonik (A) 12 combination of treatment: for the factor of Kandang Lembu fertilizer is L0 = 0 gr / polybag, L1 = 320 gr / polybag, L2 = 640 gr / polybag while the Axik ZPT is A0 = 0 cc / liter water, A1 = 1 cc / Liter of water, A2 = 2 cc / liter of water and A3 = 3 cc / liter of water. Parameters observed, height of plant (cm), stem diameter (cm), flowering plant age (day) and weight of sample plant fruit (gr). From the result of this research, it can be concluded: (1) The treatment of Kandang Lembu fertilizer gives a significant effect on the parameters of plant height, the weight of the sample plant and the stem diameter but does not give significant effect on the age of flowering plants; (2) The treatment of ZPT Atonik is not Showed significant effect on plant height parameters, stem diameter, flowering plant age and plant sample weight; (3) The interaction between cow manure and Atonik ZPT did not show any significant effect on all parameters: plant height, stem diameter, plant weight and weight of fruit of sample plant.
