Abstract

Kartikawati et al, 2017. Utilization of Rainfed Rice Areas for High Yielding Rice Cultivation on Climate Change. JLSO 6(2):142-149.Many efforts have been conducted by Indonesian government for national food supply and food security through rice cultivation on sub optimal lands in accelerating food sustainability particularly rice, maize and soybean. The rainfed area is an important sub optimal land which should be developed due to 26,5% of Indonesia rice production produced from cultivation system in those area. However, the cultivation in rainfed areas have challenges such as changing of rainfall pattern due to climate change. Therefore, to obtain the information of productivity from high yield rice varieties and methane emission in rainfed area, a study has been conducted by applying innovation of environmental friendly technology such as fertilizer use based on integrated cropping calendar. The study was carried out at Research Station of Indonesian Agriculture Environment Research Institute in Jakenan, which is one of rainfed area in Pati District, Central Java Province. The study was conducted on first growing season (GS 1) or rainy season by applying direct seeded system using rice seeder. Four rice varieties were used for this study, namely Ciherang, Dendang, Inpari 31 and Inpari 24. The study showed that productivity of four rice varieties were 5.92; 7.10; 5.06 and 7.41 t/ha, respectively. Methane emission was significant different among the varieties as 232; 319; 300 and 405 kg/ha/season, respectively.

Abstract

Sistem usahatani ramah lingkungan diartikan sebagai usahatani untuk memperoleh produksi optimal tanpa merusak lingkungan baik secara fisik, biologis dan ekologis. Selain itu sistem ini juga harus menjamin keberlanjutan sistem produksi. Pendekatan Pengelolaan Tanaman Terpadu (PTT) pada padi sawah yang bersifat ramah lingkungan diyakini dapat mengakomodasi teknologi untuk peningkatan produksi padi, sekaligus memelihara kelestarian lingkungan biofisik, serta menjaga keberlanjutan sistem produksi padi sawah.Penerapan teknologi mitigasi emisi Gas Rumah Kaca (GRK) di lahan sawah selain dapat mempertahankan dan meningkatkan produksi padi, juga dapat mereduksi emisi GRK secara signifikan.Dengan demikian maka untuk menjamin peningkatan produksi padi, sekaligus memelihara kelestarian lingkungan lahan sawah serta menjaga keberlanjutan sistem produksi padi, maka teknologi mitigasi emisi GRK di lahan sawah perlu ditambahkan dalam paket PTT.Environmentally friendly farming system is defined as afarmto obtain an optimal production without physically, biologically andecologically damaging the environment. In additionthis system should also ensure the sustain ability of production systems. Integrated crop management (ICM) aproachin paddy ricefield is believed tobe able to accommodate environmentally friendly technologies which increaserice production, maintain sustainability of biophysical environment, as well asmaintain sustainability of rice production systems. Application of GlassHome Gas (GHG) emissions mitigation technologies in paddy rice field do not only maintainand increaserice production, but also reduce GHG missions significantly. Thus,toguarantee an increase inrice production, sustainability of bio physical environment, and sustainability of rice production systems, the GHG emission mitigation technology inpaddyrice fields should be addedin the ICM package.

Abstract

The initial study that we carried out regarding the Kwanyar sub-district area, Bangkalan, East Java, shows the need to optimize land productivity and analyze the potential for farming to build the welfare of the people of the Kwanyar subdistrict. Preliminary spatial data analysis related to the topography as a result of Digital Elevation Model (DEM) data processing shows that: the Kwanyar sub-district is dominated by flat slopes (0-8°) compared to the northern region of the Kwanyar sub-district, while runoff water analysis shows a low flow coefficient (0- 0.25) which means that most of the Kwanyar area has low absorption capacity and a high potential for stagnant water. In addition, the Kwanyar region has a Regosol soil type. Regosol soil has a coarse texture and low organic matter, which makes it unable to properly hold water and minerals for plants, so it tends to be infertile. The initial study then became the basis for this research.
