Food security has been transformed into one of the strategic issue when it is related to the raise of population numbers and the high rate of irrigated land conversion into residential/industry. The increase of rice national production becomes one of the Government’s key element to meet the national food necessity. The zonation mapping process to the irrigated area potency has been conducted, however, the further analysis to determine the land development policy is necessary in correspond with the raise of production cost and investment expense. This is essential to assess its development efficacy. The main purpose of this research is to examine the best scheme to boost up the national rice productivity, either through the extentification or the intentification processes and to calculate the minimum required of the investment cost. This research is focused on the analysis towards the irrigated area, whereas the location determination is referring to these two important aspects: 1) the zonation mapping potency of irrigated land development; and 2) the simulation of categorization of the national rice productivity. The optimization process has been investigated through Multi Criteria Decision Analysis (MCDA) along with the Analytical Hierarchy Process (AHP) method. Further more in-depth scoring criteria has been canducted with the compromise Programming and Promethee methods to figure out the development priority. The total Investment cost which acquired for the average irrigated area extensification was estimated around 105,6 million IDR/ha, henceforth, it is could be referred as the basis for budgeting- stipulation process for the future irrigated area development, with the production increase resulted from the abovementioned extensification of irrigated area was 5,02 tonnes/ha, or the cost of investment per production for the pertinent irrigated area intensification was 10,51 million IDR/ton.

Chili plants (Capsicum Annum L.) requires the availability of water in sufficient quantities and timely. The situation can be achieved by the application of drip irrigation system. This is due to the system can set the amount and timing in accordance with the water requirements of chili plants. This research was conducted in Nagari Biaro, District Ampek Angkek, Agam regency which aims to design a drip irrigation system that is suitable and appropriate for chili cultivation in the greenhouse. In this study, observations were conducted to the evapotranspiration of chili (ETC), technical testing, and feasibility analysis of drip irrigation systems. Based on the research results, highest ETc of 2.16 mm/day was occurred in the period from the beginning of the generative phase, with an average discharge droplets of 137.685 mm3/sec, the system operated for 0.84 hours/day to meet the water needs of chili plants. However, by considering the three parameters of technical feasibility, the system is still not feasible because there was only one that fits the required value, namely the distribution efficiency (91.49%). The uniformity (76.97%) and irrigation efficiency (74.37%) have not yet reached the minimum required value of 90%, this is caused by differences in head and the length of each channel, thus the pressure on the line was not uniform which causing varied discharge droplets.

This study evaluates the result of implementation of water-efficient irrigation technology by using an automated roundshaped emitter, powered by solar cell. In order to determine investment feasibility of the automated system, Net Present Value (NPV), Internal Rate of Interest (IRR) and Benefit Cost Ratio (BCR) analysis have been conducted. An investment is feasible if the project fulfill the following criteria: (1) NPV is greater than zero, (2) IRR is greater than the discount rate which are applicable, (3) BCR greater than 1. The analysis shows that in general, the application of the automated system for mango, sugar apple, grapes, and chili plantation is very feasible. NPV of the investment ranges from Rp 1,533,423 to Rp 21,995,452; BCR value ranges from 1.337 to 3.775, and IRR value ranges from 17.38% to 34.10%. Implementation of the automated system for the development of mango and sugar apple plantation are the most feasible, with highest NPV, BCR and IRR. Whereas, implementation of the automated system for chili plantation is not feasible, since the value of NPV < 0, BCR < 1, and IRR < 14% interest rates. The average payback period of the automated system is about 4 year.

Nowadays, the issues of water scarcity, high fertilizer cost, and negative environmental impacts due to high agrochemicals use are escalating so that the improvement of resource efficiency on rice cultivation is necessary. Based on many studies, SRI is a very promising approach. Pot experiment was conducted under SRI framework with continuous flooding (CF), shallow water depth (SWD), and field capacity (FC) irrigation; together with four different doses of organic fertilizer (F100, F50, F0, and LF). The aim of this study is to figure out the effect of water and organic fertilizer managements on rice performances. Our experiment showed soil Eh was significantly different between three water management treatments (p < 0.05) where FC gained the highest soil Eh, followed by SWD and CF. Whereas, organic fertilizer management gave insignificant effect on soil EH. Under SWD management, number of tillers was significantly higher than CF and FC. On the other hand, water management and organic fertilization had no significant effect on plant height. SWD significantly increased yield and biomass followed by CF and FC. Organic fertilizer caused significant reduction on number of tiller, yield and biomass. In conclusion, SWD provided better environment for rice growth and enhance the rice performances, while the effect of organic fertilizer was not clearly seen.

Water security is the community's ability to maintain sustainability in meeting water demands for various purposes and managing water-related disasters. The score of Asian countries water security indicator has been formulated and calculated by the Asian Development Bank (ADB). However water security at the river basin level, including irrigation water security, has not been assessed. Like other Asian countries, irrigation in Indonesia is the largest water user, therefore irrigation water security plays important role in water resources management. This paper formulates and calculates the water security for irrigation in all river basins in Indonesia. The computation method is adopted from ADB, and developed according to the conditions of data availability and characteristics of river basins in Indonesia, under the assumption of homogeneity within river basin. It is concluded that the irrigation water security in the river basin in Indonesia is generally in "medium" condition. The "very bad" condition occurs only in Ciliwung-Cisadane and Progo-Opak-Serang river basins. The "bad" conditions include the Bangka, Belitung, Cidanau-Ciujung-Cidurian, Ciliman-Cibungur, Bali-Penida and Lombok river basins. Measures to improve irrigation water security are developing and improving performance of irrigation networks, improve reliability of water supplies by constructing reservoirs and ponds, and reducing water stress with water savings.
