Lodged plants have lower photosynthetic rate and nutrient transport capacity which resulting in lower rice quality. However, physiological process of rice plant under lodging condition is rarely reported. Therefore the objective of this research was to evaluate the biochemical compounds of two rice varieties under artificial lodging treatment. IR64 and HIPA8 varieties were planted at the Experimental Farm in Leuwikopo, Bogor Agricultural University (IPB) in November 2016 to June 2017. At grain filling stage, rice hills were enforced to lodge using manual force until culm break. Analysis of untargeted biochemical compounds was conducted at Research and Development Institute, Laboratory of Regional Health, DKI Jakarta where rice culms from upper and below breaking position were compared. Results showed that rice culms had different biochemical compounds after lodging, especially in fatty acid, terpene, alkane, and steroid group. Lodging culms had a total of 22 to 25 compounds compared to 15 to 17 of the control unlodged plants. It means that lodging stimulated different physiological process in rice plants. A decrease in fatty acid and an increase in the steroid level of lodged plants indicated an increase in oxidative stress of lodging condition. It is possible that low rice grain quality under lodging condition was caused by the changes in the plant physiological processes in response to the environmental stress.

Nilai indeks 0 : sangat tahan rebah (tidak ada tanaman yang rebah), 1 : tahan rebah (tanaman rebah kurang dari 20%), 3 : agak tahan rebah (tanaman rebah 21 I¶ 40%), 5 : sedang (tanaman rebah 41 I¶ 60%), 7 : agak peka (tanaman rebah 61 I¶ 80%), dan 9 : peka (tanaman rebah lebih dari 80%). Evaluasi karakter kerebahan (Krb) tanaman padi dilakukan mengikuti Panduan Sistem Karakterisasi dan Evaluasi Tanaman Padi Kementan (2014). Kreteria dan metode evaluasi varietas padi terhadap ketahanan rebah tidak diukur untuk menghadapi kondisi cuaca ekstrim. Nilai indeks kerebahan berubah dengan terjadinya insiden cuaca ekstrim sehingga perlu dilakukan evaluasi terhadap kreteria ketahanan rebah suatu varietas bila akan ditanam di daerah yang rawan insiden cuaca ekstrim.

However, researches on the local adaptation to their impact on rice production are limited especially on tropical region like Indonesia. A study was conducted in Pesawaran, West Lampung, North Lampung, and Bandar Lampung using time series data of 2000-2015 and ground checking during extreme weather and normal seasons and its implication on sustainable management. Data were evaluated using multivariate regressions. Results demonstrated that the impact of extreme weather on the reduction of rice production was weak, 0.92%. Shifting on rice production among swampy, irrigated, and dry lands at which covered area of 13.67%, 42.69% and 43.65%, respectively, minimized the impact of the extreme weather. During limited precipitation, irrigated and swamplands had 2.5-3.0 times cropping intensity. Conversely, during La-Nina with excess precipitation, cropping in irrigated and drylands increased by 20 and 58%, respectively. Moreover, the local government maintained annual production improvement by about 5% through expansion of irrigated land, high yielding varieties and inputs subsidies. Considering that incident of extreme weathers tended to occur more frequently, consequently, planting calender utilization and rice variety adapted should be implemented.

The extreme event is defined as strong wind at speed of 50 km.h-1 and rain fall intensity 10 to 20 mm.h-1 or more. This condition is detrimental to rice production as this may lead to lodging and flooding, particularly when the extreme weather events occur during the grain filling stage to harvesting, resulting in a significant decrease in yield and grain quality. Simultaneous extreme events and critical rice growth occured more frequently due to increasing cropping seasons within a year in Indonesia. Therefore, it is important to mitigate and develop adaptation strategies in order to sustain rice production. Efforts to adapt to these extreme environmental conditions are mostly based on genetics and agro-ecological approaches.
