Abstract

Meningkatkan budidaya bawang merah dapat dilakukan dengan berbagai teknik budidaya yaitu dengan perkecambahan benih. Tujuan dari penelitian ini untuk mengetahui peningkatan perkecambahan benih bawang merah akibat interval perendaman H2SO4 dan beberapa media tanam. Hasil yang diperoleh berpengaruh tidak nyata terhadap interval perendaman H2SO4 dan beberapa media tanam. Walaupun hasil yang diperoleh berpengaruh tidak nyata tetapi tanpa perendaman dan media kompos merupakan perlakuan yang terbaik untuk perkecambahan benih bawang merah.

Abstract

The purpose of this study was to determine the effectiveness of the herbicide dose level with the active ingredient glyphosate with the addition of 4 types of surfactants to control weeds in oil palm fields. The study used a separate plot design method with a randomized block trial pattern, testing the herbicide dose levels of 2, 3 and 4 liters of herbicide glyphosate/ha (as the main plot) and the addition of surfactant types (as subplots). The types of surfactants tested were Biosurfactant DEA, Biosurfactant DEA-3, Agristic (commercial surfactant) and Spreader (commercial surfactant) with a concentration of 0.5 ml/liter of herbicide solution. From the analysis of research data, it is known that the dose levels of 2, 3 and 4 liters per hectare of the herbicide glyphosate with the addition of 4 types of surfactants, did not show significantly different effectiveness in controlling weeds in oil palm plantation areas. The addition of DEA Biosurfactant, DEA-3 Biosurfactant, Agricultural Surfactant and Spreader Surfactant into the glyphosate herbicide solution did not significantly increase the effectiveness of the herbicide to control weeds in oil palm plantations. The herbicide glyphosate with the addition of 4 types of surfactants was effective in controlling Asystasia gangetica and Cyrtococcum oxyphillum weeds, but was not effective in suppressing the growth and development of Syngonium podophyllum and Adiantum latifolium weeds. Keywords: herbicide, glyphosate, weed, surfactant

Abstract

Herbicides are needed by farmers to control weeds in their farming land. Although the price of herbicides is expensive, farmers always try to buy them. The need for working capital to buy herbicides is one of the factors that drives the increase in farm production costs. The initial survey of potential partner farmers illustrates that farmers are familiar with and have used various types of herbicides. However, all farmers in Dusun Bah Bulawan do not know how to make or reproduce herbicides. All farmers depend on buying commercial herbicides from agricultural kiosks, which are relatively expensive and tend to increase from year to year. Based on the situation analysis of partner farmers, a concept was formulated, namely how to make farmers' knowledge change from not knowing to knowing in terms of multiplying herbicides. The strategy of the activities carried out is to organize training. Farmers are equipped with technological knowledge to reproduce their own herbicides. With the skills of being able to reproduce their own herbicides, it is hoped that farmers can save production costs. Because the cost of buying herbicides can be reduced by a significant amount. The general objective of training activities is to help farmers overcome their problems and reduce farm production costs. Meanwhile, the specific objective is to increase the welfare of farmers through savings in farm production costs. Benefits of the activity: the knowledge and skills of farmers will increase, especially the technology for increasing herbicides. While the impact of activities: (a). Farmers gain additional knowledge of technology transfer from universities and create synergistic cooperation between universities and the community. (b). Farmers know more about the use of herbicides as weed control. (c). Farmers' knowledge changed from not knowing to knowledgeable in terms of multiplying herbicides. (d). Farmers are able to multiply their own herbicides to reduce farm production costs. (e). The level of income and welfare of farmers is expected to increase, because production costs for controlling weeds can be saved
