Abstract

Soybean is a plant that has a significant role in responding to food needs and improving people's nutrition because it is an economically affordable source of vegetable protein when compared to other protein sources such as meat, milk and fish. The use of superior seed varieties and supported by the use of appropriate fertilizer also has a very important role in the continued growth of soybean plants. This research used a Randomized Block Design (RAK) with 2 factors and 3 replications to obtain 36 research plots. Factor I Biological Fertilizer (H) which consists of 4 levels, namely: H0 = 0 ml/liter.air/plant, H1=10 ml/ liter.air /polybag, H2=20 ml/ liter.air/polybag, H3= 30 ml/ liter. water/polybag. Factor II Soybean Variety (V) which consists of 3 levels, namely: V1 = Dega 1 Variety, V2 = Ring 1 Variety, V3 = Devon 1 Variety. The results showed that the use of biological fertilizer had no significant effect on all observed parameters, whereas The use of varieties has a very significant effect on all observed parameters. Keywords: soybean, fertilizer, varieties

Abstract

Soybean (Glycine max L.), which is widely grown in Indonesia, is a popular food crop because of its high protein content. This plant plays an important role in increasing protein intake for the community, because it is a safe and economically affordable source of vegetable protein. To increase the productivity of soybean plants, it is not only important to choose quality seed varieties, but also to implement appropriate cultivation practices. One of the main techniques is to use superior seed varieties. Apart from that, increasing the quality and yield of soybean production can be achieved by providing fertilizer that meets the nutritional needs of plants. This research used a Randomized Block Design (RAK) with 2 factors and 2 replications to obtain 24 research plots. Factor I of Branglai Fertilizer (B) which consists of 4 levels,namely: B0=0ml/liter.air/plant, B1=20ml/liter.air /polybag, B2=40 ml/liter.air/polybag, B3 = 60 ml/ liter. water/polybag. Factor II Soybean Variety (V) which consists of 3 levels, namely: V1 = Dega 1 Variety, V2 = Ring 1 Variety, V3 = Devon 1 Variety. The research procedure consists of making fertilizer, land preparation, filling polybags, planting, fertilizer application branglai (soybean stover), determination of sample plants, maintenance and harvest. Keywords: soybean, branglai fertilizer, soybean variety

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

Abstract

In oil palm plantations, weed control using herbicides is considered more practical than other control methods. This is due to the need for less manpower, shorter control execution times and longer control cycles. The ability of herbicides to control weeds is determined by the type of active ingredients they contain. The aim of the study was to determine the effectiveness of the 2 types of herbicides and the appropriate dosage levels to control weeds in oil palm fields. The research method used a nested design, testing 2 types of herbicides namely fluroxypyr-mepthyl and ammonium glufosinate. While the second treatment, tested the dose level of each herbicide. The tested dose levels for the herbicide fluroxypir-mepthyl were 0.1 l/ha, 0.3 l/ha, 0.5 l/ha, 0.7 l/ha and 0.9 l/ha. While the dose levels of ammonium glufosinate herbicide were 2.6 l/ha, 2.8 l/ha, 3.0 l/ha, 3.2 l/ha and 3.4 l/ha respectively. The results showed that the effectiveness of the herbicides fluroxypir meptyl and ammonium glufosinate to control weeds in oil palm plantations was not significantly different. The most effective dosage level of the herbicide fluroxypir meptyl for controlling weeds was 0.9 l/ha (average percentage of weed mortality was 74%). The dosage level of the ammonium glufosinate herbicide which resulted in the highest percentage of weed death (74.44%) resulted in an application dose of 3.4 l/ha. Application of the herbicides fluroxypir meptyl and ammonium glufosinate at all dose levels tested did not show toxicity in oil palm plants.

Abstract

The research was carried out in people's coffee plantations at 4 locations at different altitudes in Simalungun Regency. The aim of the research was to determine the intensity of attacks by the coffee berry borer Hypothenemus hampei Ferr on land at different altitudes, and to determine the effectiveness of synthetic attractant traps to control it. The research method used a series design (randomized design series groups), which was carried out on coffee plantations at altitudes of 550, 850, 1,000 and 1,150 meters above sea level. At each plantation location, in an effort to control Hypothenemus hampei Ferr attacks, 3 (three) types of synthetic attractant traps were installed: Hypotan 500 SL, Koptan and Atrakop 500 L. The results of the research showed that the intensity of Hypothenemus hampei Ferr attacks tended to decrease in coffee plantation locations. higher above sea level and vice versa. The attractant types Hypotan 500 SL, Koptan and Atrakop 500 L showed no significant difference in effectiveness for trapping the coffee berry borer Hypothenemus hampei Ferr. However, these 3 types of attractants have not been able to reduce the intensity of attacks from puso, heavy and moderate categories to light attack categories.
