Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Penilaian pilar irigasi untuk mengukur tingkat kesiapan menuju modernisasi irigasi diperlukan dalam rangka implementasi modernisasi irigasi di Daerah Irigasi Belitang. Ketersediaan air irigasi menjadi pilar yang perlu untuk dioptimasi sebelum implementasi modernisasi irigasi. Tujuan penelitian ini adalah menilai dan mengkaji kesiapan modernisasi irigasi, menetapkan prioritas pengembangan modernisasi pada Daerah Irigasi (DI) Belitang, serta menentukan alokasi air optimal sebagai upaya meningkatkan pilar keandalan penyediaan air. Metode IKMI digunakan untuk mengukur kesiapan modernisasi irigasi DI Belitang sedangkan metode Analytical Hierarchy Process (AHP) digunakan untuk menentukan prioritas kebijakan pengembangan modernisasi irigasi. Optimasi alokasi air dimaksudkan untuk menambah luas tanam dianalisis dengan program linier. Hasil penelitian menunjukan bahwa berdasarkan hasil penilaian indeks kesiapan modernisasi irigasi yaitu 69,05, DI Belitang masuk dalam kategori cukup. DI Belitang pada tingkat wilayah belum siap untuk dimodernisasi sehingga diperlukan pengembangan dan perbaikan sistem irigasi terlebih dahulu selama 1 sampai 2 tahun. Pengembangan dan perbaikan kinerja menuju modernisasi irigasi berdasarkan analisis dengan AHP mengikuti urutan Belitang III, Belitang I dan Belitang II. Keuntungan maksimum dan luas tanam optimal dengan optimasi alokasi air diperoleh dengan penerapan Golongan pada wiayah DI Belitang dan pola tanam padi-padi-palawija. Penerapan Golongan di 3 wilayah DI Belitang dapat menghindari defisit air tetapi terdapat surplus air pada Masa Tanam (MT) I dan MT II. Dengan demikian, optimasi alokasi air dapat menjadi upaya dalam peningkatan keandalan penyediaan air irigasi.
