Abstract

Control of Grayak Caterpillar (Spodoptera exigua Hubn) pest by farmers generally is still use synthetic insecticides that have such a negative impact resistance, resurgence, killing natural enemies, increasing residue on crop yields, environmental pollution and health problems for users. One effort to reduce the use of chemical insecticides namely biological control method uses the Spodoptera exigua Nucleo Polyhedro Virus. This research was aimed to know the mortality rate army worm (Spodoptera exigua Hubn) by suspension Spodoptera exigua Nucleo Polyhedro Virus with different concentration. This research was conducted in the laboratory and green house of Vegetable Crops Research Institute at Lembang, Bandung from July until September 2014. This research used Randomized Completely Design (RCD). The result showed that Spodoptera exigua Nucleo Polyhedro Virus was significant to death of Spodoptera exigua. Spodoptera exigua Nucleo Polyhedro Virus concentration showed significant to mortality rates of Spodoptera exigua. In the test stage, the larvae of Spodoptera exigua 2 was the highest stage mortality was caused by infection Spodoptera exigua Nucleo Polyhedro Virus. Method of dipping caterpillars and feed applications were the best treatment because it showed the highest mortality. Pest control Grayak Caterpillar (Spodoptera exigua) in the field could use Spodoptera exigua Nucleo Polyhedro Virus coarse suspension of 10 g L-1 which was applied to the onion crop that was attacked.Keywords: Spodoptera exigua, Spodoptera exigua Nucleo Polyhedro Virus, Onion

Abstract

This study aims to determine land suitability class for of plantation crops, namely; cocoa, arabica coffee and durian in Cemplang region, Ciomas district, Serang Regency. The research used several stages of research method including; collecting data and information, determining soil sample points and field surveys, taking soil samples and field observation, conducting laboratory analysis and assessing land suitability classes. Data processing was carried out using GIS through the ArcGIS application by overlaying and applying the matching method of land suitability parameters. The results showed that the assessment of land suitability at two sample points for cocoa plants was quite suitable (S2) with limiting factors for nutrient retention and erosion hazard, arabica coffee plants were not suitable (N) with temperature limiting factors, while the durian plants were by the marginal (S3) with the limiting factor of water availability. Efforts to improve the land can be made by making terracing, making drainage, applying agroforestry patterns, adding organic matter, liming and fertilizing.Keywords: land suitability, plantation crops, SIG
