Abstract

Sheet pipe is a type of perforated pipe used for drainage designed initially for drainage but has the potential for sub-surface irrigation. The objectives of this study were to experiment and observe the performance of the sub-surface irrigation control system with sheet pipe. This investigation covered the observation of water table control and its effect on soil moisture. The detailed process of water flow during the setting of the water table was numerically modeled in 2 dimensions to observe the distribution of soil moisture, soil pressure, and flux. The results showed that the system successfully controlled the water table at the desired level in the experiment. The developed two-dimensional numerical simulation showed the distribution of soil moisture in the model center as a response to the water table increase, represented by the variable head. The soil wetting advances toward soil surface driven by the water table, which was increased gradually and reached saturation at the height of water table setpoint.

Abstract

The current study aims to develop a simple model for estimating greenhouse gas emissions originating from paddy fields, utilizing backpropagation neural networks. The model integrated three input parameters: soil moisture, soil temperature, and soil electrical conductivity (EC), while generating estimations for two output parameters: methane (CH4) and nitrous oxide (N2O) emissions. The model was put into practice across three different irrigation systems, i.e., continuous flooded (FL), wet (WT), and dry (DR) regimes. For model training and validation, the input parameters were measured by a single 5-TE sensor. Concurrently, CH4 and N2O emissions were determined utilizing a closed chamber, and gas samples were subjected to laboratory analysis. Findings unveiled that the developed model accurately estimated CH4 and N2O emissions, demonstrating commendable coefficient of determination (R2) values ranging from 0.60 to 0.97 for validation process. Notably, the WT irrigation system exhibited the highest precision, boasting R2 values of 0.97 for CH4 and 0.73 for N2O estimation, respectively. Conversely, the FL irrigation system has the lowest accuracy with R2 values of 0.66 and 0.60. Despite variances in accuracy across irrigation systems, the overall performance remained deemed acceptable, warranting the model's applicability for estimating greenhouse gas emissions under diverse irrigation scenarios.

Abstract

Indonesia is known as an agricultural country because most of its people cultivate rice in rice fields. BPS through the area survey framework (KSA) stated that the total harvest area in 2022 was 10.45 million hectares. This large area is very likely to cause inefficient water use in rice cultivation considering that most of the cultivation is carried out by inundation. Measurement of irrigation water needs in rice fields has been carried out mostly in the analysis stage, no detailed measurements have been found in evaluating irrigation water needs in rice fields. Evaluating the need for irrigation water in rice fields can easily be done with a water balance approach that considers all aspects of both incoming and outgoing water. This study aims to examine the components of irrigation water needs in the land preparation period. The study was conducted on rice plots equipped with several measuring instruments. Measuring water discharge in and out using CTF, weather data using AWS, and percolation measurements in the field. Measurement of water demand in rice fields on the plot resulted in a total inflow value of 195.38 mm and rainfall of 40.40mm. The total value of evapotranspiration occurred was 104.11 mm, the percolation value was 54.00 mm and the discharge out value was 29.59 mm, so the water loss was 48.08 mm (24.61%)

Abstract

Currently, in KP-01 the determination of irrigation water requirements for land preparation (KAIPL) for rice fields is still based on the Van de Goor & Zijlstra (VGZ) equation with the assumption of constant discharge. This method is practical in planning but tends to be wasteful in implementation. Therefore, the aim of this paper is to develop an empirical model for determining KAIPL that is more water efficient by implementing intermittent irrigation. The model was developed from the application of inundation at certain periods and water levels for three different soil textures. The empirical model was developed from the VGZ equation by adding constants as factors for intermittent irrigation and soil texture (called the MVGZ model). Then compared with the results of measurements in the field during 2 growing seasons in DI Cihea, West Java. The results show that the constant values for the MVGZ model with heavy, medium and light soil textures are 0.79; 0.76 and 0.73. With this constant, accuracy is obtained with a coefficient of determination (R2) of 0.99. Field validation results show that the MVGZ model is close to the measurement results with water savings of 28-34% compared to the VGZ model. Therefore, the MVGZ model can be applied to determine KAIPL which is more water efficient.

Abstract

Human resilience is related to the availability of natural resources, such as water, which is developed through community empowerment and technology. Nganti Village, Bojonegoro is one of the villages that is vulnerable to the availability of clean water for daily consumption. So, this research aims to  (1) analyze the problems and potential of water sources that are not utilized by the Nganti community, (2) analyze community strategies in dealing with water problems, and (3) simulate alternative membrane technology based on community empowerment. This research used a combined approach, quantitative and qualitative, involving key informants, including the Village Head, Head of the Clean Water Association, Ngraho Sub-district Head, and Community Leaders, in addition to a survey of 40 Nganti-Ngraho residents. Data analysis is descriptive statistical and qualitative. The water quality of a spring in Nganti Village shows that the water is not suitable for drinking, washing and latrines (MCK) due to the high content of iron and other metals. Meanwhile, the community's strategy is to use water reservoirs as an alternative water source and introduce membrane technology through community empowerment activities.

Abstract

Wilayah terluas sebagai penghasil beras di Pulau Jawa adalah Kabupaten Indramayu. Sebagian besar Kabupaten Indramayu berada di daerah pesisir, airtanah menjadi sumberdaya yang sangat dibutuhkan untuk irigasi pertanian. Eksploitasi yang berlangsung secara terus menerus dan volum yang semakin meningkat dari waktu ke waktu menyebabkan terbentuknya ruang kosong di lapisan akuifer sehingga ruang kosong pada tanah kemudian diisi oleh air laut. Pada penelitian ini Jaringan Saraf Tiruan (JST) digunakan untuk memprediksi intrusi air. Tujuan penelitian untuk menentukan peta zonasi intrusi berdasarkan kualitas airtanah, yaitu total dissolved solid (TDS) ,dan daya hantar listrik (DHL). Penelitian dilakukan di 33 kecamatan dengan 83 titik sampling pada bulan Februari 2017. Luas sawah di Kabupaten Indramayu sekitar 57,94%, dengan kontur berupa dataran rendah dengan daerah endapan di timur laut. Pasokan air permukaan Kabupaten Indramayu berasal dari DAS Cimanuk, Cipunegara, dan Cipanas. Pada musim kemarau air tanah Kabupaten Indramayu sudah dieksploitasi berlebihan untuk sumur bor sebagai irigasi. Akuifer bebas terletak 3 - 30 meter di bawah permukaan tanah, dengan tebal sekitar 15 - 20 meter, mengalir dari selatan ke utara. Topografi Kabupaten Indramayu berada pada ketinggian 0 - 100 meter di atas permukaan air laut dengan kemiringan rata-rata 0 - 2%. Hal inilah yang menyebabkan Kabupaten Indramayu tergenang air saat curah hujan tinggi. Nilai kualitas airtanah didapat bahwa bagian utara dan timur lebih besar dari selatan dikarenakan batas pantai terletak di bagian utara dan timur.Keywords: EC, Indramayu District, intrusion, TDS

Abstract

Global warming occurs due to increased concentrations of GHGs in Earth's atmosphere. CH4 gas is one of the GHG which potentially 21 times greater to result global warming than CO2. Emissions of CH4 in rice fields affected by irrigation pattern and micro environmental factors. This research aimed to identify the relationship of micro-environmental factors to CH4 emissions and analyse its sensitivity level. The sensitivity analysis of CH4 gas in this study was done by rank Spearman’s correlation method. The results showed that the irrigation pattern was positively correlated with CH4 emissions. Total flux of CH4 for the stagnant regime was 26.00 ± 3.41 x 103 mg/m2/season, wet regime was 15.33 ± 4.37 x 103 mg/m2/season, and dry regime was 11.80 ± 6.72 x 103 mg/m2/season. The micro-environment parameters that was soil pH, soil moisture, soil electrical conductivity, and water level are positively correlated with flux of CH4, meanwhile soil temperature and soil redox potential are negatively correlated with flux of CH4. Based on the analysis, the most sensitive micro-environmental parameters for CH4 gas emissions are soil moisture, with an average rs value is 0.51 and an average R2 is 0.28. Keywords: GHG, methane, sensitivity analysis, Spearman’s correlation, SRI

Abstract

Bogor as tourist destination at weekend bear quite high vehicles volume. The purpose of this research was to analyze corelation between vehicles volume at highways gate and NOx exposure from the vehicles. By knowing the average concentration of NOx exposure level pollution risk to the health of highway gate worker could be analyzed. This research using Griess Saltzman method referring to SNI 19-7119.2-2005 using some equipment like impinger. The result showed that type of vehicle that produced the highest amount of NOx pollutant was vehicles with diesel engine, and the gate with highest NOx concentration was gate 08 with NOx concentration value 40.008 µg/m3 at 09.00-10.00. Risk quotient (RQ) to the workers with weighed 65-90 kg and had been working for 25 years was 0.041950 and it was RQ < 1. It meaned that the average pollution caused by NO2 at the highways gate does not affect workers and workers does not cause any health risk because RQ < 1. For the next research, it would be recommended to conduct on O3 and NO3, because those compounds are easily reacted with NOx in the air.

Abstract

Conventional paddy field with continuous flooding irrigation produces a lot of greenhouse gases (GHG) emissions, especially methane gas (CH4). Effective water management is important to reduce methane gas emissions from paddy fields. This study aimed to determine optimum water level and soil moisture in each plant growth stage by genetic algorithms (GA) with system of rice intensification (SRI) practices. Research was conducted with three irrigation regimes i.e, continuous flooding regime (FR), moderate regime (MR), and dry regime (DR). Observation data were used to simulate the optimum water level and soil moisture. Based on the optimum water level scenario of the GA model, methane gas emissions could reduce 63.54% and optimum soil moisture can reduce methane gas emission up to 58.12%.Keywords: genetic algorithms, greenhouse gases, soil moisture, SRI, water level
