This research presents the development of information system for irrigation asset management, called Sistem Informasi Management Asset Irigasi-Jaringan Tersier (SIMAI-JT). The SIMAI-JT was designed as a management tool for tertiary irrigation network. The development phase of SIMAI consists of system design, coding, and implementation. The design phase includes structural and functional design. The program was designed and developed using VBA application over the GIS-platform. The input data was the spatial data in the form of points, polylines and polygons that describe the component of the irrigation network. The input data was acquired from the field survey (using camera and GPS) and digital conversion from the existing maps. Furthermore, all the spatial data obtained were converted to GIS layers. Then, the system integrated and display those layers in the form of photo, satellite imagery, and table information. Finally, an irrigation water user association at farmer level or Himpunan Petani Pemakai Air Irigasi (HIPPA) Sido Mulyo which located at Karangsono, District Bangsalsari, at the regency of Jember was selected to test the systems. The design was calibrated based on the capability and needs of HIPPA. The result shows that the information system must be designed with (i) showing maps according to the satellite imagery, identification and potential damage of tertiary irrigation network accompanied by the photo of the structure, (ii) artificial intelligence in determination of damage priority, and lastly (iii) institutional performances. The outcome of this program is being utilized in the meeting for planning institutional strategy in handling of tertiary irrigation network damage(s).

Ligarmukti Village in Bogor Regency is a karst hilly area that is rich in springs so that it can supply water for domestic and agricultural purposes. The chemical properties of water derived from limestone have their own characteristics which probably have an impact on the quality of agricultural products. Thus, this study was conducted to analyze the hydrochemical properties of karst springs for irrigation. Research methods were secondary data inventory, hydrogeological observation, and laboratory analysis. Sodong is the largest spring with a discharge of 314.42 l/s in the rainy season and 154.38 l/s in the dry season. Rice field area is approximately 300 ha. The discharge from the spring can irrigate rice fields covering an area of 314.14 ha in the rainy season and 154.38 ha in the dry season. In addition to discharge, water chemical factors also determine agricultural yields. Groundwater hydrochemical including Ca-HCO3 facies, groundwater flow systems are controlled by autogenic recharge which shows the type of water in the spring from rainwater directly infiltrated in the area. Classification of water for irrigation including C2-S1 type which shows that spring has good water quality, a risk of medium salinity, and low sodium risk. The results of this study can be used by the government to maintain the village of Ligarmukti as an agricultural granary.

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.
