Abstract

Evaluation of acute toxicity of endosulfan insecticide in natural water environment was conducted to know its potential negative effect to the Nile (Oreochromis nitoticusi. Using static toxicity test method, the acute toxicity of7 endosulfan concentration levels were tested afterstandardized for 96 hours in the solution of water from river, pond and paddy field. Four replications were implemented into those treatment and ground water was being a control. The size of Nile used in the examination was 3-5 gr/tails in weight. Result of the examination was revealed by medium lethal concentration value LC50 -96 hours. The result indicated that insecticide of endosulfan in the solution of water from three kind environment had the high toxicity effection the Nile. The values of LC50 -96 hours were 6.00 mg/Lin the river water, 4.61 mg/Lin the pond water and4.51 mg/Lin the paddy field water, respectively. The difference of those values was caused by the difference of water quality such as total hardess, organic matters, total and suspended solid, and endosulfan residue in the water.

Abstract

Since last four years, area harvested and production of tobacco in Temanggung District tended to decrease due to the low price of tobacco. It forces farmers to search alternative commodities. Survey to find out the role of estate crops for poor farmers was carried out in September-October 2004 inTernanggung District. The assessment involved 91 farmers who coming from three sub districts, i.e. Pringsurat Sub District (medium land), Kaloran and Kledung Sub Districts (both are high land). Results showed that in general agricultural sector was an important as a source of income, in which contributed 30,6 % and 45 % for medium and high land respectively. For high land farmers, estate crops contributed the highest percentage (14%) followed by food crops (12%). The dominant estate crops were coffee, tobacco, coconut, clove, and cacao. Tobacco showed the highest revenue (Rp. 2,505 millions/household), even though also needed the highest production cost (Rp. 1,586 millions/household). In medium land, estate crops were in the fourth placed (5%) after livestock (9%), forestry (8%), and horticulture crops (6%). Dominant commodities were coffee, coconut, and clove. Marketing system was not different in both areas. Aside of coconut, estate crops was firstlyprocessed before being sold in village and sub district markets, in which was paid in cash. For tobacco commodity, traders were the source of price information, while for other commodities were neighbours/other farmers. Based on the analysis, efficiency could be increased through scaling up the farm size. Fanning consolidation was promising to be implemented

Abstract

Changes in precipitation patterns, increase in frequency of extreme climate events, and rise in temperatures and sea level were serious impacts of climate change faced by Indonesia. Agriculture is the most vulnerable sector influenced by of the climate change. In the current condition, optimizinyon natural resource utilization is one of ways to recover economic condition of farmers. The use of reservoir on dry land aimed to conservation water resource and restrain erosion rate is the best cheap and efficient solution. Then, water retained can be used for agriculture in dry season. This rain water harvesting is suitable for rainfed ecosystem which has uncertain intensity and distribution of rainfall. This study aimed to identify the production of onion cultivated in dry area around reservoirs, to give alternative farming around reservoir in order to increase income for farmer. The study was conducted in Getas village of Kradenan district, and Randublatung village of Randublatung district in Blora regency. The Result of this study indicated that the average onion production in Getas village and Randublatung village was 10.33 t/ha and 11.63 t/ha with R/C ratio of 1.45 and 1.59, respectively. The farmers very strong motivation could support the successful implementation of new plant cultivation although their level of knowledge and experience also influenced the successful farming . Farmer perception on onion cultivation technology on land araund reservoir was very positive
