“…Their values were 30% and 27% more than those values for conventional production. The same results also observed by the previous study that reported SRI farming increased water productivity from 0.82 to 1.12 g/kg (Fuadi, Purwanto, & Tarigan, 2016).…”

ABSTRAKPenelitian ini dilakukan untuk menganalisa efektifitas irigasi berselang dengan neraca air pada lahan SRI dengan penerapan pupuk organik. Eksperimen dilakukan di Desa Gabus Wetan, Kab. Indramayu, Jawa Barat dari 17 November 2016 sampai 1 Maret 2017. Sensor parameter cuaca dan tanah dipasang di lahan untuk mendapatkan data harian kondisi lapang termasuk pertumbuhan tanaman. Data cuaca seperti hujan, suhu udara, kelembaban udara relatif, dan kecepatan angin dan kedalaman muka air diukur secara otomatis setiap 60 menit. Analisis neraca air dilakukan dengan kesalahan (error) yang rendah (1,00%) dimana jumlah air masuk melalui hujan dan irigasi sebesar 560 mm dan 865 mm, sedangkan jumlah air keluar melalui evapotranspirasi tanaman, perkolasi, dan limpasan berturut turut sebanyak 430, 306 dan 675 mm. Perbandingan dengan sistem pertanian konvensional dengan irigasi tergenang, menunjukkan bahwa produktivitas air dari SRI organik berturut turut 30% dan 27% lebih tinggi untuk produktivitas air berdasarkan jumlah air masuk dan evapotranspirasi. SRI organik juga memproduksi 33% produksi lebih tinggi dari sistem pertanian konvensional di lokasi yang sama. Kunci keberhasilan irigasi berselang adalah dengan menjaga tinggi muka air dipermukaan tanah (macak-macak) pada fase vegetatif dan generatif. Oleh sebab itu, cara ini merupakan alternatif pilihan bagi petani ketika sumber daya air berkurang karena perubahan iklim. Diseminasi hasil direkomendasikan melalui program pelatihan dan pendampingan bagi petani.Kata Kunci: SRI organik, pengelolaan air, neraca air, produktivitas, sistem monitoring ABSTRACTThe current study was carried out to analyze effectiveness of intermittent irrigation by water balance components in SRI paddy fields with organic fertilizer. The experiment was conducted in Gabus Wetan Village, Indramayu District, West Java, Indonesia from 17 November 2016 to 1 March 2017. Weather and soil sensors were set up in the fields to acquire data on daily field conditions as well as on plant growth. Data on weathers such as precipitation, air temperature, relative humidity, and wind speed were collected automatically during the season every 60 min, as well as the soil water depth. Analyzing the data collected, water balance analysis was well performed with low error (1.00%) in which the water inflows through precipitation and irrigation were 560 mm and 865 mm, respectively, while the outflows by crop evapotranspiration, percolation, and runoff were 430, 306 and 675 mm, respectively. Compared to conventional rice farming as commonly practices by applying continous flooding irrigation, water productivities of organic SRI were 30% and 27% higher with respect to total water input (WPIR) and with respect to the amount of evapotranspiration (WPET, respectively. Organic SRI produced 33% higher yield than the average of conventional methods in the same subdistrict. The key was intermittent irrigation by maintaining shallow water depth (nearly soil surface) in the vegetative and generative stages. Therefore, it is an attractiv...

“…Though water is one of the important elements in rice farming. This is in line with the results of [27] research which states that limited water conditions can cause a decrease in rice productivity, the use of water for rice plants, among others, in the process of fertilization, plant density and crop protection which processes determine actual results and also maximum yield that can be achieved in a cropping system.…”

The pressure of global market demand for palm oil is driving a massive expansion of oil palm plantations in Indonesia. Although it provides benefits in economic terms, it also has social and environmental impacts. The impact is in the form of changes in the ecological landscape, conversion of agricultural land, rural household livelihood systems, reduced biodiversity, deformation, plant monoculturalization, and even a monostructuring of livelihood. This study aimed to provide an overview of changes in the ecological landscape that resulted from the expansion of oil palm plantations and the socioeconomic impact of the expansion of oil palm plantations on farmers' household livelihood systems. The study was conducted in West Sulawesi, Indonesia. This study uses the livelihood survey method by selecting 30 farmer households selected by random sampling. The results of the study found the fact that oil palm plantations seemed to provide welfare for rural households, but what happened was a vulnerability and high livelihood dependence on income from the wages of oil palm plantations. The expansion of oil palm plantations has created the integration and dependence of rural economies on the global political economy of oil palm, but at risk to even undergoing household livelihood dilemmas due to the two villages' deliberate divergence of livelihoods because of shifting ecosystems now leading by palm oil commodities.

“…Pada stadia pengisian malai, tingkat keparahan penyakit ratarata 38,33% pada MK dan 35,37% pada MH. Inokulasi pada stadia anakan maksimum dan bunting menunjukkan tingkat keparahan penyakit yang tinggi, karena memberikan waktu lebih panjang pada penyakit Fuadi et al (2016) melaporkan bahwa air diperlukan tanaman padi terutama pada stadia anakan maksimum sampai pengisian malai untuk proses transpirasi dan fotosintesis. Pada stadia tersebut tanaman memerlukan air untuk melarutkan unsur hara bagi pertumbuhan dan perkembangan tanaman padi (Bouman 2009).…”

Sheath blight is a major disease of rice caused by Rhizoctonia solani. A screen house test was conducted to determine the critical stages of rice plant growth to the pathogen infection That cause rice yield reduction. Three rice varieties namely Ciherang, Minghui 63, and Hipa Jatim 2 were inoculated with R. solani inoculum at four different plant growth stages (maximum tillering, panicle initiation, flowering, and maturity) during dry and wet season. Results showed that the disease severities among plots inoculated at different plant stages as calculated in the form of Area Under the Disease Progress Curve (AUDPC) varied markedly. AUDPC values were the highest when the plants were inoculated at their maximum tillering and booting stages. Rice yield loss was higher in plot with a higher values of AUDPC. There were no significant differences in disease severities between resistant and susceptible rice varieties. The seemingly suitable control for sheath blight is when the plant enter the maximum tillering stage to minimize the rice yield loss.
