The System of Rice Intensification (SRI) has been known in Indonesia since 1999. However, there are some difficulties in utilizing SRI water management recommendations in the field, particularly in combination with organic nutrient management. While many demonstrations have given impressive gains in productivity, many farmers remain skeptical about applying this system. The current study was carried out to analyze water balance components in SRI paddy fields when applying intermittent irrigation. The experiment was conducted in Gabus Wetan village, Indramayu District, West Java, Indonesia from 17 Nov 2016 to 1 March 2017. We involved a local farmer who had been trained in SRI methods at an Organic SRI Center on how to conduct organic SRI management in his fields. 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 that 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 attractive option to farmers in irrigated areas where water resources is limited due to regional climate change effects. Keywords:

Paddy is the main agricultural commodity in Indonesia that needs a large amount of water. Accurate prediction of crop water use is essential to have an efficient irrigation system. The actual evapotranspiration (ETc) is an important factor for estimating water use. Moreover, crop coefficient (Kc) is one of the important parameters in ETc calculation. In this study, Kc of paddy is estimated by using experimental pots under various water tables treatments. The water table is controlled by using mariotte tube and set at -12 cm, -7 cm, -5 cm, -3 cm, 0 cm, and +2 cm from the soil surface. From the experimental sets, the value Kc is calculated by using modified water balance equation and Kalman Filter. The result shows that water table treatment in paddy farming influences soil moisture ( ) and soil temperature (Tsoil). Soil physic parameter fluctuation due to water table treatment affects the plant growth and potential evapotranspiration. Kc value at each water table treatment is different, and varies with plant growth phase. The average Kc for all water table treatments are 0.77-1.27 (initial season), 0.90-1.11 (crop development), 1.10-1.39 (mid-season), and 1.17-1.40 (late season).

Escalation of the scarcity in water resources has stimulated the development of a different method to preserve water in the paddy field. Several studies have been carried out simultaneously to observed the effectiveness of various water regimes on sustaining water, mitigating greenhouse gases (GHG), and maintaining rice yields. Irrigation management is a critical factor in controlling Methane (CH4) and Nitrous oxide (N2O) emission in the paddy field. The aim of this research is to evaluate the Denitrification-Decomposition (DNDC) Model in estimated greenhouse gas from various water regime management. This research conducted from January until May 2018, in plot experiment used SRI method under three different water regimes: flooding regime (RT), wet regime (RB), and dry regime (RK). DNDC Model was created to predicted CH4 and N2O emission in the agricultural ecosystem. This model already used and evaluated in subtropical land, but the ability of this model still needs to evaluate for soil in the tropical area such as Indonesia. The emission result showed a different pattern between the simulation model and observation model. The coefficient of determination (R2) from CH4 and N2O emission simulation with actual fluxes are 0.123 and -0.237. The finding in this study indicated that the simulation model needed improvement to be able to estimate the CH4 and N2O emissions from Indonesia’s environmental condition.

The paper proposes the artificial neural networks (ANN) model to predict methane (CH4) and Nitrous Oxide (N2O) emissions under different irrigation system based on easily measurable environmental biophysics parameters such as soil moisture, soil temperature and soil electrical conductivity. To verify the model, two experiments were conducted in the pot experiments in two different locations. The first location was in the greenhouse of Meiji University, Kanagawa Prefecture, Japan from 4 June to 21 September 2012, and the second location was in water resources engineering laboratory, Department of Civil and Environmental Engineering-IPB from 2 July to 10 October 2014. In each location, there were three different irrigation systems adopted with the System of Rice Intensification (SRI) principles. We called the experiment as SRI Basah (SRI B1 and SRI B2 for the first and second locations, respectively), SRI Sedang (SRI S1 dan SRI S2) dan SRI Kering (SRI K1 dan SRI K2). Each treatment has different water level during growth stages. As the results, the developed ANN model can predict CH4 and N2O emissions accurately with determination coefficients of 0.93 and 0.70 for CH4 and N2O prediction, respectively. From the model, characteristics of those greenhouse gas emissions can be well identified. For the mitigation strategy, SRI B1 and SRI B2 treatments in which the water level was kept at nearly soil surface are the best strategy with highest yield production and lowest GHG emission.

Controlling water table is the way to manage water in SRI paddy field. Farmers tend to apply different water table depend on their local water management practices. It may have different effect on plant growth that can be seen in the number of tillers. In this study, tiller development of SRI paddy was studied by using experimental pots under various water tables treatments. The water table is controlled by using mariotte tube and set at -12, -7, -5, -3, 0, and +2 cm from the soil surface. The result shows that soil moisture (Ɵ) were fluctuated due to intermittent irrigation and water table treatment. It affects the tiller growths rate that varied with average value 0.21-0.29 tiller/day. The first tiller appears at 18 days after transplanting (DAT). The tillers number keep increasing until reaching the highest number (around 63 to 72 DAT). This empirical study showed that setting water table at -5 cm under soil surface in SRI paddy cultivation is the best to reach high tiller number, and highest land and water productivity compare to another water table treatments. Consistency in producing tiller from beginning tiller production until the end of cultivation season could be seen from this treatment.

Increased awareness of precision agriculture in water management, requires various ideas and methods for its application in the fields. One idea that can be categorized into precision farming as well as appropriate technology, is evaporative irrigation. Evaporative irrigation is an idea to control the provision of irrigation water based on the direct response of plant water needs, namely evapotranspiration. The objectives of this study were to: (1) examine the theoretical aspects of the evaporative irrigation to be applied to plots of rice fields in a plot of plots with irrigation units, (2) laying out design principles for evaporative irrigation valve closures. The results showed that, theoretically, a controller pipe was needed which would be an indicator for thick water in the plot of rice fields. The pipe controller regulates the opening of the irrigation lid to the plot based on the float-ballast principle. The design principle is carried out by simulating the reduction in the controller water level of the controller which illustrates the decrease in thick water plots. Water depth that is still tolerated for rice growth will be the limit for the provision of irrigation water to the plots. Amount of irrigation water provided is equal to the value of plant water needs in the ongoing rice growth phase. One example of the design of the controller pipe water level to start and stop irrigation is at 117.8 mm water level and 300 mm respectively. The total water needs of one crop-season is calculated to be 625 mm. With the application of evaporative irrigation, the initial conditions of sufficient water do not require the provision of irrigation water until the 31st day. Irrigation water application after that, until harvesting, requires only 477 mm. Giving this water follows the plant water requirements calculated on a day-to-day basis.

System of Rice Intensification (SRI) is known as alternative rice farming for the mitigation of greenhouse gas (GHG) emissions. There are two main gasses emitted from paddy fields, i.e., methane (CH4) and nitrous oxide (N2O). Both of these gases have different characteristics as response on water availability in the fields which is represented by groundwater levels. Global Warming Potential (GWP) is used as an index that allowed comparisons of the global warming impacts of different gases at specific time period to warm the earth and it is equivalent to the value of the potential of CO2. This study aimed to analysis the global warming potential from different water regimes with SRI practices. Achieving the objective, rice cultivation with three water regimes was carried out during one planting season (14 April until 5 August 2016) in experimental plots of Department of Civil and Environmental Engineering IPB, Bogor, Java West. The regimes were continous flooding, moderate and dry regimes, respectively. The results showed that dry regime has the lowest global warming potential than those others regimes. Its potential was 34% and 41% lower than those for flooding and moderate regimes, respectively. In addition, dry regime produced more grain yield. Its productivity was 21% greater than that flooding regime. These results were obtained from specific climate and location. To corroborate the results, further research is needed under different weather conditions and multi-locations.

Lembaga Penelitian dan Pengabdian kepada Masyarakat (LPPM) IPB organizes a Lecturers Community Service Program, as an innovation of lecturers community service by facilitating lecturers to several villages in Bogor and outside of Bogor to directly interact and provide solutions for the community. The purpose of these activities is to enhance the implementation of science and technology from the university for society welfare. One of the villages partners in this program is Cihideung Udik Village with prominent agricultural potential. More than 60% of the land is used for agriculture. Yet, until now the community still face agriculture problems such as decreasing agricultural land area due to changes into residential house. This condition triggers a decrease in the availability of ground water, and cultivation type or pattern change. Previously the community cultivate paddy, but now the community shifts to plant secondary crops especially corn. Not only that, various complex problems in Cihideung Udik require innovative solution available at universities such as IPB University. Lecturer community service at Cihideung Udik was carried out through the socialization of necessary materials viz., future skills motivation, family financial planning, water saving irrigation, water saving cultivation, agrosilvofarmaka, mapping of village potential and marketing. This activity preceived to be useful and any material delivered by the lecturer in general, were needed by the community. Although there was a material that need to be evaluated in order to increase public knowledge. Therefore, the Lecturer Community Service Program have to evaluate and improve their system in responding to community problems and also continuously improve community welfare.

Produksi air lindi akibat tumpukan sampah akan mencemari lingkungan dan air tanah di bawahnya apabila tidak diolah dengan baik. Air lindi memiliki banyak padatan tersuspensi sehingga memerlukan koagulan sebagai pengikat antar partikel padatan. Penelitian ini merancang unit sedimentasi primer dengan mempertimbangkan kecepatan pengendapan ketika diberi koagulan. Berdasarkan hasil pengujian jar test diperoleh dosis optimum PAC 2500 mg/L karena memiliki nilai turbiditas dan COD terkecil berturut-turut sebesar 0.46 NTU dan 163 mg/L. Dosis koagulan terpilih selanjutnya dilakukan pengukuran hindered settling sehingga menghasilkan nilai ketinggian kritis 15,9 cm dan waktu kritis 76,7 menit. Proses pengendapan zona kompresi terjadi pada menit ke-183 ditandai dengan melandainya kurva. Desain unit sedimentasi primer berdasarkan karakteristik kecepatan pengendapan pada air lindi dapat mengadopsi persamaann Vesilind dan Yoshida-Dick. Nilai koefisien pengendapan dengan persamaan Vesilind dan Yoshida-Dick masing-masing sebesar 2 × 10-6 m3/gr dan 9,82 × 10-3 m3/gr. Persamaan Vesilind menghasilkan nilai kecepatan pengendapan sebesar 0,009 cm/detik, sedangkan persamaan Yoshida dan Dick sebesar 0,01 cm/detik. Berdasarkan kurva hindered diperoleh nilai Hu sebesar 5,23 cm dan Tu sebesar 183,74 menit. Nilai Hu dan Tu dapat memperoleh nilai SOR sebesar 2,39 m3/m2. Debit aliran ditentukan sebesar 100 L/detik maka diperoleh nilai luas area permukaan sedimentasi sebesar 3614,74 m2 dan diameter unit sedimentasi diperoleh sebesar 66,67 m. Kedalaman total dan diameter unit sedimentasi primer diperoleh sebesar 4,59 m dan 66,67 m. Desain struktur unit sedimentasi terdiri atas struktur influen, orifice submerge EDI, dan struktur efluen agar debit influen yang memasuki unit sedimentasi tidak mengganggu proses pengendapan. Hubungan antara nilai pemodelan kecepatan pengendapan dengan desain unit sedimentasi diharapkan mampu mengoptimumkan proses pengendapan pada air lindi dengan menggunakan koagulan PAC.

Dalam Kriteria Perencanaan (KP-01) tentang Perencanaan Jaringan Irigasi disebutkan bahwa penentuan kebutuhan air irigasi untuk penyiapan lahan ditentukan dengan persamaan Van de Goor & Zijlstra (VGZ). Perkembangan teknologi usahatani pada pengolahan tanah dengan mekanisasi mempercepat waktu pengolahan tanah serta penggenangan yg hemat air menjadi pertimbangan melakukan evaluasi kebutuhan air. Makalah ini bertujuan mengevaluasi penentuan kebutuhan air irigasi penyiapan lahan dengan model VGZ dan membandingkan dengan model neraca air (water balance analysis (WBA)) dengan menerapkan irigasi berselang. Dalam evaluasi, simulasi dan penelitian lapang dilakukan khususnya untuk melakukan validasi model WBA di lahan Balai Besar Peramalan Organisme Penggangu Tanaman (BBPOPT), Karawang, Jawa Barat. Simulasi dilakukan pada tekstur tanah liat berat dengan dua kondisi perkolasi (P = 1,5 mm dan P = 2,0 mm) dan evaporasi (E = 3,5 mm dan E = 5,5 mm) dengan periode penyiapan lahan 20 dan 30 hari. Hasilnya menunjukkan kebutuhan air irigasi pada model VGZ berkisar antara 303 – 379 mm atau setara 1,46 – 1,92 l/det. Sedangkan model WBA membutuhkan air irigasi yang lebih kecil berkisar antara 142 - 275 mm, dengan debit sebesar 0,74 l/det dan 1,11 l/det. Model WBA dapat menghemat air irigasi sebesar 27 – 42%. Hasil simulasi ini didukung hasil observasi lapang dengan koefisien determinasi model (R2) sebesar 0,97 sampai 0,99. Dari hasil ini, penentuan kebutuhan air irigasi pada penyiapan lahan di KP-01 perlu ditinjau ulang dengan memperhatikan periode lama penyiapan lahan yang lebih singkat dengan penggunaan traktor maupun kebutuhan tinggi genangan setiap proses penyiapan lahan
