Pacal Irrigation System in Bojonegoro District is an irrigation system designed to apply surface irrigation gravitationally. Pump uses to abstract irrigation water from canals to irrigate rainfed area outside the system was against the original design. This paper aims to develop the decision making model to decide optimum pump use to achieve optimum operation pattern. The choice of optimum operation pattern was developed using the Analytical Hierarchy Procees (AHP) method to meet the irrigation management aspects. Alternatives of pump operation used were no pump, 68 pumps, 47 pumps, and 21 pumps. Criterias to choose pump operation pattern were RWS, RIS, KPA, efektiveness dan eficiency. The results showed that main criterias to affect the choice of pump operation patteren were RWS and RIS with proportion as 40,73% and 28,19% respectively. Considering all criterias, the optimum pump operation pattern was operation with 47 pumps.ABSTRAKDI Pacal di Kabupaten Bojonegoro adalah sistem irigasi teknis yang didesain untuk menerapkan irigasi permukaan dengan cara gravitasi.

This paper aims to make a comparation between the performance of irrigation system in early irrigation policy reform and that of the recent condition. Van der Wijck Irrigation System in Yogyakarta was chosen as case study. Early data was collected through questioner and participatory method. Fuzzy set theory was employed to determine the most unsustainable aspect for the irrigation system. It revealed that economic aspect was the most threaten aspect. Because of abundant water, farmers in the upper area of Van der Wijck grow rice in the entire year. However, farmers received very small amount income from their land. Recently most of them convert their rice fields into shrimp ponds because it financially gives more benefit. On the other hand this sectoral development created upper-lower conflicts among water users within the system. This policy change would affected technology and management in the system.ABSTRAKPaper ini bertujuan untuk membandingkan kinerja sistem irigasi pada awal pemberlakuan reformasi kebijakan irigasi dengan kinerja saat ini. Daerah Irigasi Van der Wijck di Yogyakarta dipilih sebagai kajian kasus. Data awal dikumpulkan dengan kuesioner maupun secara partisipatif. Teori himpunan kekaburan digunakan untuk mengetahui aspek yang paling tidak berlanjut dalam sistem irigasi. Hasilnya menunjukkan bahwa aspek ekonomi merupakan aspek yang paling terancam. Karena banyaknya air, petani di daerah hulu Daerah Irigasi Van der Wijck membudidayakan padi sepanjang tahun, namun petani tidak menerima banyak keuntungan dari budidaya ini. Beberapa tahun terakhir ini, banyak petani mengkonversi sawahnya menjadi tambak udang yang secara ekonomis memberikan banyak keuntungan. Meskipun demikian, pengembangan secara sektoral ini menimbulkan konflik hulu-hilir antar pengguna air dalam sistyem irigasi. Perubahan kebijakan ini dapat berpengaruh pada teknologi dan manajemen di dalam sistem irigasi.

Planting pattern in an irrigation system is affected by water availability in river which may fluctuate from time to time. The objective of this paper is to assess the discharge fluctuation characteristic of Bedog and Gajahwong Rivers measured respectively in Cokrobedog and Mrican Weirs. The historical discharge data of the two rivers was assessed to predict river discharges of subsequent year as a basis of planting pattern determination. The ARIMA model was employed to predict water avalability. Model test showed that ARIMA (1,1,0) and ARIMA (2,1,0) could accurately predict river discharge of the two rivers. Considering parsimony principle, the ARIMA (1,1,0) model was chosen as the most suitable model. Based on predicted discharge, the previous planting pattern can still be applied in the future.ABSTRAKPola tanam pada sistemirigasi dipengaruhi oleh ketersediaan air di sungai yang bervariasi dari waktu ke waktu. Tujuan penelitian ini adalah untuk menganalisis karakteristik fluktuasi debit Sungai Bedog dan Sungai Gajahwong yang masing-masing diukur di Bendung Cokrobedog dan Bendung Mrican. Data historis debit kedua sungai dianalisis untuk menentukan karakteristik dan memprediksi debit pada tahun berikutnya sebagai dasar penyusunan pola tanam. Model ARIMA dipergunakan untuk memprediksi ketersediaan air. Uji model menunjukkan bahwa ARIMA (1,1,0) and ARIMA (2,1,0) mampu memperkirakan debit kedua sungai. Dengan mempertimbangkan prinsip parsimony, maka model ARIMA (1,1,0) dipilih sebagai model yang paling sesuai. Berdadsarkan prediksi debit, pola tanam sebelumnya yaitu padi-padi-palawija masih dapat diberlakukan di masa yang akan datang.

Sleman, as an area with rapid economic growth, againts the challenge of development in relation with population expansion, local autonomy and good governance. In one hand, there is lack of synergy among development stakeholders, on the other hand. information is ineffectively used during the decision making process. This paper aimed to develop a model of rural development plan based on agricultural sector using two computer softwares,(i) Geographical Information System (GIS) as spasial information system and (ii) Powersim to program the dynamic system behaviour. The model provides information on existing condition and consists of five components namely geography, development function, infrastructure, institution, and data catalog. The model was developed through formulating causal diagrams of development sectors and set it in a dynamic programming. The model was then validated in Moyudan, Sleman for the case of agriculture development, which is showed that the model was valid.

It is indicated that the level of performance of an irrigation systefrz affects the benefit received by farmers. Low level of performance leads on the low farmers' income, which furthermore affects farmers' welfare. On the opposite, farmers with low level of welfare have limited capability to manage their irrigation system so the level of performance of the system declines. This created a vicious circle of low performance and poverty. This paper aims to assess irrigation system peformance, relate the performance with poverty in the system, and examine possibilites of poverty alleviation through improvement of irrigation system performance. Irrigation performance assessment comprises of characterization of irrigation system and performance assessment by using indicators. The study has been conducted in four irrigated systems in Java, namely Klambu Kiri, Glapan, Kalibawang, and Krogowanan. Lesson learnt were drawn from cases of the selected systems to find out factors affecting irrigation performance and how irrigation system performance affects farmers' welfare. Possible efforts to improve irrigation system performance to alleviate poverty are crop diversification, Irrigation Management Transfer, empowerment of Water Users' Association (WUA), locally specific farming, and off farm job opportunity. To implement those efforts there are some constraints to deal with, such as limited technical capability of farmers, diversity of social and culture, and limited available data and information.

One among the policies in Irrigation Management Policy Reform (IMPR) is the Irrigation Management Transfer (IMT). Through the IMT, farmers in Water Users' Association (WUA) manage their own irrigation systems. The IMT let farmers to diversify their farming system to achieve farmers' welfare. The diversification results in in the variation of planting pattern in an irrigation system. The variation is bigger if market plays a role in crop choice. Therefore, the assumption that an irrigation system has a uniform performance throughout the system is no longer valid. This paper aims to examine the distribution of an irrigation system managed by farmers. The system chosen as sample was Mejing Irrigation System in Banjul, Yogyakarta. The performance was assessed by using adequacy and water delivery performance. The spatial distribution of Mejing Irrigation System is mainly affected by irrigation operation pattern as well as condition and serviceability of irrigation network Spatially, the tertiary blocks located in the head receive more water than other tertiary. blocks in the tail.

Model of sustainable pump operation in an unconfined groundwater irrigation system was developed to determine pump operation pattern which consist of the number of pumps, duration, and distance between pumps, so that crop water requirement is fulfilled and groundwater irrigation system is sustained. Total irrigation flow, EQpi, results in lowering water table which is called drawdown, sn. Drawdown sn should be less than di (sn< di) which (d1 is maximum drawdown which is affected by pump technology. Model outputs for the area of Sri Rahayu Farmer Group in Kedungtuban, Blora for existing cropping pattern show that average irrigation water requirement is 916.1mm/year and peak flow is 4.93 ips. It still can be fulfilled by 1, 2, 3, 4, or 9 pumps for 10 days operation continuously which is shown by the drawdowns which are less than maximum drawdown.

The food requirement in Indonesia is highly dependent on rice and its requirement is increasing. On the other hand, the avalability of natural resource especially land and water are getting more limited. Consequently,there is a need to increase rice production with efficient resources. On the other hand, there is a necessity to apply sustainable agriculture. SRI (System of Rice Intensification) method was developed to deal with the problems. In the field, the SRI method still shows a wide variation of yields, therefore researches are necessary to reveal the phenomena behind this method. This paper aims to develop mathematical models of rice tillers and plant height of rice growth as well as to compare the growth of rice plants at several locations and treatments. Mathematical models developed were the rice tillers’ growth model which follow the exponential polynomial function order 2 and the crop heights model which follow the monomolekuler function. The number of seedlings from one seed planted in SRI would result more tillers than conventional crops after more than 30 days after planting. Conventional crop height was relatively higher than that of SRI because close spacing and inorganic fertilizers trigger vegetative growth.Keywords: mathematical model, SRI, crop physiology, rice

There are five pillars in the irrigation network management, one of them is the improvement of irrigation network facilities and infrastructure. The improvement of irrigation network facilities and infrastructure is divided into two activities, namely development and management. Related to these activities, there are many locations in the irrigation area that require prior handling. This study purposed to analyze the priority of ten irrigation systems of district authority spread over D.I. Yogyakarta for optimizing the implementation of management of irrigation networks. The analysis used (Multiple Attribute Decision Making) MADM which consists of SAW, WP, TOPSIS, Electre and AHP methods. Five parameters used in the analysis, including main irrigation network infrastructure, tertiary irrigation network infrastructure, water availability, service area, and crop productivity. The study proved that the tertiary irrigation network in 10 irrigation systems of district authority in D.I. Yogyakarta suffered moderate to severe damage in a number of 65 locations. There were 11 locations that always appear at the top of each MADM, which were priority proposals for irrigation network development and management activities. In addition, there was a tendency that the higher the irrigated area, the higher the priority of development or management of a location. If there are several proposed locations with similar conditions, the determination of priorities can be determined based on the irrigated area.

It is possible for farmers, through Federation of Water Users’ Association (WUAF), as direct users to participate in the management of the irrigation system main network. The government of Yogyakarta Special Region (DIY) encourages WUAF to participate in the main network management so farmers understand the system comprehensively so that irrigation will be better managed and sustainably. This paper aimed to assess WUAF participation in irrigation system management as well as to identify factors influenced the participation level and to formulate strategies to improve WUAF participation. Based on their performances, WUAFs were clustered into three clusters, namely cluster 1 for WUAFs with good performance in all aspects, cluster 2 for WUAFs with financial weakness, and cluster 3 for WUAFs financial and institutional weaknesses. Strategy proposed for cluster 1 was minor government intervention to maintain WUAFs performance. Strategy proposed for cluster 2 and cluster 3 was pursuing independent funding source. Additional strategy for cluster 3 was institution strengthening through routine meetings and field workers. General strategies applicable for all clusters were improvement of WUAF role in the management of main network supported with appropriate training and selection of high-value agricultural commodities.
