Although there have been many studies in system of rice intensification, but a little evidence in relationships with field monitoring system in Indonesia, especially in East Nusa Tenggara Province. East Nusa Tenggara (NTT) Province, a province with consists many islands, typical monsoon climate with low annual rainfall. The aim of this study is using Field Monitoring System (FMS) as an adaptation strategy of system of rice intensification (SRI) cultivation against regional climate change. For this study, field monitoring system was set up in the SRI and conventional field since 26 July 2016 in Kupang, NTT Province that is consisted of three main components, i.e., FieldRouter, Datalogger and the sensors. Here, there are several sensors that have been installed in the field, e.g., solar radiation, rain-gauge and soil moisture. In one planting season, we tried cultivated SRI and conventional rice farming. As the results, the IT field monitoring system showed good performance and reliable for adaptive climate change rice farming with SRI in East Nusa Tenggara. The actual field conditions were monitored well in term of image, numeric, and graphical data acquisition. Based on monitored data, plant growth can be well monitored. In addition, dynamic changes of environmental parameters can be monitored as well. Based on those data, we found that SRI rice farming was more efficient in water use than that conventional rice farming. The water use can be saved up to 12%. SRI also increased water and land productivities respectively were 5.12% and 16.36%. This results proven that SRI can be alternative rice farming that more adaptive to climate change.

System of Rice Intensification in Terrace Rice Field: Plant Growth Rate and Nitrogen Availability
( Rizki Maftukhah ),( Bayu Dwi Apri Nugroho ),( Chusnul Arif ),( Kazunobu Toriyama ),( Kazuhiko Kobayashi ) 한국농업기계학회 2018 한국농업기계학회 학술발표논문집 Vol.23 No.1
About 90% of Indonesian people used rice as staple food. Rice production needs large amounts of water, especially under conventional rice production system. Recently, system of rice intensification (SRI) is promoted as an alternative rice cultivation to maintain rice yield through optimizing water and nutrient efficiency. This system use organic fertilizer, wide space, and intermittent irrigation. In this study, we evaluate performance of rice plant growth between conventional and SRI method in terrace rice field. Different cultivation method will affected on rice plant development and nutrient availability. We used two different treatment, continuous flooding (FL) as practiced by farmer and system of rice intensification (SRI). FL was used continuous flooding and SRI was used intermittent irrigation during rice growth. Three consecutive terraced paddy fields (100-150 m²) were used for the experiment. Rice plant growth measured every week and rice yield at harvest time. Total nitrogen and nitrogen availability determined from soil samples after harvest time. Rice plant growth was analyzed by monomolecular and polynomial model. Rice plant growth rate resulted that plant height was not significantly different between SRI and FL (p>0.005), although in different terrace. However, number of tillers rate showed that SRI was significantly increased tillers (p<0.005). Terrace two resulted higher tillers than terrace one and three, both in SRI and FL. Number of tiller have positive correlation with rice yield. The yield comparison resulted that SRI was significantly different with FL (p<0.005). Yield was increased under SRI method. In addition, total nitrogen and nitrogen availability under SRI field was higher than FL field.
