This community service took place in Simatohir Village, Padangsidimpuan District Angkola Julu, Padangsidimpuan City. The implementation methods used are counseling methods, cultivation technique training, and mentoring. The approach method used is: a) Counseling about the application of SRI technology. b) Make demonstration plots or demonstration plots. c) Use of 2 : 1 legowo planting system using ticks. In the generative phase clearly visible results from the application of SRI are applied to the rice field cropping. There is a distance that facilitates the care of farmers, efficiency in the use of paddy water and the number of productive tillers is 25-40 tillers / clumps and the yield reaches 1337 tons with an area of ​​1000 square meters and this difference is very obvious when farmers do not use SRI , which starts from tillage which is only extracted, unbalanced fertilization, irregular irrigation, perforated plants between 10-20 plants with productive tillers only 15-23 tillers. This will have an impact on harvest yields which only reach 900 kg with an area of​​ 1000 square meters.

ABSTRACT The aim of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the SRI method, and to get the best time of gliricidia MOL application on the growth and production of lowland rice. Field research has been conducted in Tara-Tara II Village, West Tomohon Subdistrict for five months starting from June 2017 until November 2017. Treatment in the experiment consists of one treatment factor, that was interval time of gliricidia MOL application, ie  : 0, 5 , 10, 15, and 20 days. The results showed that time application of gliricidia MOL have an effect on the number of productive tillers, the number of filled grain/panicle, the number  of empty grain/panicle, and the dry grain yield (GKP) / plot, but not affect the plant height. The best results were achieved in gliricia MOL application on interval time every 15 days with a values were : 28.66 productive tillers; 176.90 fillet grain/panicle; 19.80 empty grain/panicle (lowest); and 9.50 kg dry grain yield or equivalent to 7.92 ton/ha.Keywords: gliricidia MOL, production, lowland rice,  System of Rice Intensification  (SRI)

Increasing rice productivity has been the main priority for the Government of Indonesia to meet people's food needs, however, there are a number of obstacles such as technology adoption. This study aims to explore the condition of farmers' cultivation, especially in terms of planting systems, varieties developed and reasons for selecting varieties in three different land topographic types (low, medium, and high). Sampling was done purposely with a total sample of 45 farmers who cultivate rice. Data collection includes observation and structured interview, data were analyzed descriptively. The results showed that most of the planting system that developed in three types of topography is the ‘tegel’ planting system, other technologies such as “jajar legowo” and system of rice intensification (SRI) have low developed. This is influenced by the new planting system need more skilled labor, more expensive input, and lack of farmers' knowledge. Local rice varieties have declined significantly, dominated by certain superior varieties. The main reason for selecting varieties is due to high productivity and disease resistance. In addition, the accessibility of rice seeds by farmers at the nearest farm shop. This research suggested more intensive mentoring efforts should be done through farmers’ group meetings and improvement of supporting facilities, furthermore the Local Government should improve farmers' affordability of quality seeds.

<p>Agricultural sector contribute significantly to the total GHG emission. There are some GHG mitigation options available but so far non of these mitigation options is being implemented by farmers. There is no real action have been taken by government to encourage farmers to implement the available mitigation option to reduce GHG emission from wetland rice field. We discuss some mitigation options and we suggest two additional GHG mitigation options namely crops rotation and System of Rice Intensification (SRI) that probably more attractive to farmer to implement them. However the impacts of these two proposed options as GHG mitigation options should be studied further.<br />Key words: Greenhouse gases (GHG), mitigation option, farmer contribution, SRI, crop rotation</p>

IbM Rice Farmers Empowerment Using SRI (System of Rice Intensification) in District Namorambe was held in Namorambe and Cinta Rakyat Village involving two partners who work as rice farmers. The problems of Mitra 1 in Namorambe Village are (a) number of seeds used 40-50 kg / ha, (b) seed age 20-25 days, (c) planting range 15x15 cm, (e) number of planting plants 4-5 seedlings (f) artificial fertilizer 400kg urea / ha + 150kg SP-36 / ha + 150kg KCl / ha, (g) watering elevation 20-25 cm. The problems of Mitra 2 in Cinta Rakyat Village are (a) the remaining rice straw is not processed, (b) the haystack becomes the pest of rats and fungi, (c) the soil hardens and quickly dries, (d) the straw is burned. IbM program is implemented using participatory approach, training, extension method and descriptive approach method. Impact of empowerment at Mitra 1 has been able to carry out the manufacture of paddy field plot of SRI method with production of 875 kg / 1000 m² (8.75 tons / ha); an increase in production of about 3.45 tons / ha or equivalent to 65.09%. Impact of empowerment at Mitra 2 that has been able to produce organic fertilizer from the remaining straw; has been able to manage the remaining rice straw to prevent pests and diseases; not burn the rest of the straw; and able to utilize organic fertilizer to enrich the soil.

SUMMARYField experiments were conducted in 2005 and 2006 to investigate the impacts of alternative rice cultivation systems on grain yield, water productivity, N uptake and N use efficiency (ANUE, agronomic N use efficiency; PFP, partial factor productivity of applied N). The trials compared the practices used with the system of rice intensification (SRI) and traditional flooding (TF). The effects of different N application rates (0, 80, 160 and 240 kg ha−1) and of N rates interacting with the cultivation system were also evaluated. Resulting grain yields with SRI ranged from 5.6 to 7.3 t ha−1, and from 4.1 to 6.4 t ha−1 under TF management. On average, grain yields under SRI were 21% higher in 2005 and 22% higher in 2006 than with TF. Compared with TF, SRI plots had higher harvest index across four fertilizer N rates in both years. However, there was no significance difference in above-ground biomass between two cultivation systems in either year. ANUE was increased significantly under SRI at 80 kg N ha−1 compared with TF, while at higher N application rates, ANUE with SRI was significantly lower than TF. Compared with TF, PFP under SRI was higher across all four N rates in both years, although the difference at 240 kg N ha−1 was not significant. As N rate increased, the ANUE and PFP under both SRI and TF significantly decreased. Reduction in irrigation water use with SRI was 40% in 2005 and 47% in 2006, and water use efficiency, both total and from irrigation, were significantly increased compared to TF. With both SRI and TF, the highest N application was associated with decreases in grain yield, N use efficiency and water use efficiency. This is an important finding given current debates whether N application rates in China are above the optimum, especially considering consequences for soil and water resources. Cultivation system, N rates and their interactions all produced significant differences in this study. Results confirmed that optimizing fertilizer N application rates under SRI is important to increase yield, N use efficiency and water use efficiency.
