Abstract

The objectives of this research were to determine the species composition, distribution pattern and virus transmission properties of N. virescens. Sweep net sampling of the leafhopper and others tungro vectors population were conducted from endemic areas in Central Java, East Java and Bali and also non endemic areas from Central Java and East Java. The species composition and distribution pattern of the leafhopper were studied in seedbeds and early stage of rice crop (30 days after transplanting). Inoculation test using Cisadane seedlings was conducted to determine the efficiency of virus transmission by N. virescens colonies. Four tungro virus vectors were found in all areas, namely N. virescens, N. nigropictus, N. malayanus, and Recilia sp. The domination of N. virescens occurred either in the endemic area or the non endemic areas. However, the domination of N. virescens did not correlate with the occurrence of the disease in the endemic area. The distribution pattern of N. virescens was regular. The number of N. virescens active transmitter in the endemic area was higher than that in the non-endemic areas. In addition, the female of N. virescens was more efficient in transmitting the tungro virus than that of the male.

Abstract

The organic farming community Al Barokah was formed in the village of Ketapang, sub-district of Susukan, district of Semarang in 2004, which includes the farmer group Al Barokah 3 and the farmer group Walisongo. The wish to cultivate organic rice has arisen in 2002, and was followed-up by studies for more information, know-how and skills. The area of land that is cultivated organically increases steadily each year, and is currently almost 300 ha. In 2015, through the accompaniment of LPPM UNS, an organic certificate from organic certification institution was obtained. One of the important problems faced by the organic farming community Al Barokah is the availability of water for irrigation, especially in dry season. Therefore, there is a need for a science-technology (Iptek) program for the community: Implementation of an irrigation well system for the organic rice farmer group to increase the production of organic rice. The project is conducted from June to October2017. Group participative method is used, because active participation from the community in every step of the program is required by supporting the resources of the farmer group.
