Abstract

Oil palm is a pre-eminent commodity in Indonesia, especially in Riau Province. The main pests that attack the oil palm is the pest of beetle Oryctes rhinoceros. The life cycle of pre-adult O. rhinoceros is on the ground, while the one that attacks the plant is the beetle stadia. The application of oil palm empty bunches (OPEB) to oil palm cultivation that functions as mulch and soil compost can improve the physical and biological properties of the soil, otherwise O. rhinoceros actually increases its population with OPEB application. The objective of this research is to know the population of O. rhinoceros in oil palm plantation given mulch of empty palm oil bunches. Research using survey method, observation done at PT. Adei Plantation & Industry. Observations made on the pradati with the size of the soil as a sample, to catch the adult beetles used ferotrap using pheromones as much as 5 ferotrap on 10 ha of land. Observations included the pre-adult population, the beetles population of O. rhinoceros, sex ratio, biomass, attack intensity. The results of research that has been done showsthat in the low adults population were the average of 8 tails per week, instar 2 most found was 15 tails. The population of beetles O. rhinoceros were the average of 23.8 tail / ferotrap / month. Population O. rhinoceros 1st week and 2nd, 3rd week decreased, lowest was at 4th week. The sex ratio of female and male beetles was 19.4: 4.4 or 4.54: 1. The intensity of O. rhinoceros attack was 11.72 ± 2.01% belonging to the category of minor attacks.Keywords: beetles O. rhinoceros, oil palm empty bunches, fluctuations, population.

Abstract

Spodoptera litura is main pest destroyer leaves of soybean leaves. As an alternative replacement of synthetic insecticides is bioinsecticides by utility basic ingredients from plant that are easy find such as Piper aduncum L.. The purpose of the research is to find out of a better surfactants concentration which can enhance the effectiveness of Piper aduncum L. extract below 10% which is the concentration 75 g/l of water to control S. litura of soybean. The research was conducted at the Laboratory of Plant Pests, Faculty of Agriculture, University of Riau from March to May 2016. The Research was conducted experimentally by using completely randomized design (CRD), which consists of 4 treatments, where each treatments was replicated 4 times to obtain 16 experimental units. The treatments used in the research were 0 %, 0.025%, 0.037% and 0.050% concentration of surfactants given as the extract of Piper aduncum L. concentration of 75 g/l water. The result showed the addition of several concentrations of surfactants hasn’t been able to increase the effectiveness of the concentration of ekstract Piper aduncum L. under 10% that is concentration of 75 g/l water as bioinsecticides in controlling the S. litura. But the addition of surfactants on the concentration of 0.05% (recommended dose) can increase the death of S. litura as big as to 7.5%. Keyword : Spodoptera litura F., surfactants, Piper aduncum L

Abstract

Sweet corn cultivation has several obstacles, namely reduced cultivated area, limited productive land area, high level of land conversion and low soil fertility. One of the efforts to increase soil fertility is the giving of cow urine and NPK fertilizer because it can improve the physical, biology and soil chemistryproperties. This study aims to determine the effect of cow urine and NPK fertilizer combination and get the best dose of growth and production of sweet corn (Zea mays saccharataSturt). This experiment was conducted experimentally using Factorial Randomized Block Design consisting of 2 factors and 3 replications, namely cow urine (0.75 ml/plant) and NPK factor (250, 350, and 450 kg/ha). The observed data obtained were analyzed using analysis of variance and continued with Duncan test at 5%. The results showed that giving of cow urine and NPK fertilizer had a significant effect in increasing the growth and production of sweet corn plant. Giving 75 ml of cow urine/plant and NPK fertilizer 450 kg/ha had the best ability to increase the growth and production of sweet corn.Key words: Sweet corn, cow urine, NPK fertilizer.

Abstract

Soybeanis a source of vegetable protein and the basis of variety of processed products. Chrysodeixis chalcites is one of the major pests in soybean plant. Currently efforts in controlling C. chalcitesstill use synthetic insecticide that can have negative impacts. Reducing the effects caused by synthetic insecticide, therefore need alternative in pest control techniques such as use local entomopathogenic fungi Cordyceps militaris. The purpose of this research is to get concentration of local entomopathogenic fungi C. militaris which best in control C. chalciteson soybean plants. Research prepared using completely randomized design (CRD) with 5 treatments and 5 replications. The treatment used is some concentration of local entomopathogenic fungi C. militaris consists of 5 treatments are 20 g/l of water (45,2 x 107 kon/ml), 30 g/l of water (67,8 x 107 kon/ml), 40 g/l of water (90,4 x 107 kon/ml), 50 g/l of water (113,0 x 107 kon/ml), and 60 g/l of water (135,6 x 107 kon/ml). The results showed concentration of local entomopathogenic fungi C. militaris 60 g/l of water (135,6 x 107 kon/ml) is the best concentration because can to provide the fastest time to early death for 45,4 hours, lethal time 50 (LT50) for 113,8hours, and caused total mortality 84% for 168 hours. The exact concentration to control 95% of the population of C. chalcites is 18,59% or 185,9 g/l of water. Keyword:Local entomopathogenic fungi Cordyceps militaris L.

 Fruit flay is a pests of the citrus orange in Kampar District. Observation species and population fruit fly pest to determine the pest control. This study aims to determine the type and population fruit fly (Bactrocera spp.) That attack citrus plants and fruit flies attack percentage in the village of Kuok, Kampar. Research has been conducted with a purposive sampling method with the criteria citrus orchards and attack fruit fly pests. The observation did on two gardens to be attacked with fruit flay that Rudi pack with an area of 0.5 ha and 0.25 ha Ahmad garden with a distance that is 6 x 6 m. Plant samples selected systematically method with zig-zag pattern. Intake of fruit flies imago done in two ways: first, by making use of petrogenol traps the observed daily for 7 days. Second, making fruit on the ground attacked performed once at the start of the study. The parameters measured were the description of the location, species and population fruit fly, the percentage of attacks. Datas were analyzed statistically do tabulation and calculated the average population and deskription in tables, and images. The results of such studies fruit flies were caught in the petrogenol trap is B. carambolae, B. papayae and B. umbrosa.
