Abstract

Keberhasilan sektor pertanian tidak terlepas dari manajemen pengelolaan sistem jaringan irigasi dan peran serta pemangku kepentingan yaitu pemerintah dan pengelola subak. Sampai saat ini masih banyak permasalahan yang dialami dalam pengelolaan jaringan irigasi akibat kurang optimalnya peran serta pemangku kepentingan, lambatnya respon penanganan terhadap masalah pengelolaan jaringan irigasi sehingga berdampak pada tidak meratanya pembagian air dari saluran tersier ke areal pertanian. Hal ini juga terjadi pada Daerah Irigasi (DI) Tiyingtali yang mengalami permasalahan jaringan irigasi seperti terjadinya sedimentasi pada saluran sekunder yang mengakibatkan besarnya volume pelimpahan air saat musim hujan, serta kurang optimalnya pembagian air dari hulu ke hilir. Sehingga penelitian ini bertujuan untuk menganalisis peran serta pemangku kepentingan dalam pengelolaan jaringan irigasi pada DI Tiyingtali. Pendekatan yang digunakan dalam penelitan adalah dengan pendekatan eksploratif dan metode deskritif analitis. Pengumpulan data dilakukan menggunakan kuisioner dan wawancara. Teknik pengambilan sampel/responden pada penelitian ini menggunakan metode purposive sampling, yaitu responden yang menangani pengelolaan jaringan irigasi di DI Tiyingtali yang mecakup pemerintah 25 responden dan pengelola subak 33 responden. Analisis data dilakukan menggunakan regresi linear untuk menganalisis pengaruh peran serta pemangku kepentingan terhadap pengelolaan jaringan irigasi. Selanjutnya dilakukan analisis deskriptif dari hasil wawancara untuk merumuskan upaya peningkatan kinerja dan peran serta pemangku kepentingan. Hasil penelitian menunjukkan pemangku kepentingan berperan sebesar 68,3% dalam pengelolaan jaringan irigasi, sedangkan 31,7% sisanya dipengaruhi oleh faktor lainnya. Pemangku kepentingan secara bersama-sama berpengaruh signifikan secara simultan dan secara parsial terhadap pengelolaan jaringan irigasi artinya peningkatan peran serta pemangku kepentingan secara simultan maupun parsial akan meningkatkan kegiatan pengelolaan jaringan irigasi.

RISK MANAGEMENT AT THE CONSTRUCTION STAGE OF IMPROVING THE IRRIGATION NETWORK OF THE SUNGI RIVER WATERSHED AREA IN TABANAN REGENCY ABSTRACT The implementation of irrigation network improvement project in Sungi River Watershed is quite complex because it is related to water regulation system by water user farmer association (subak). In the implementation there are various risks that may affect the cost, quality and timing of the project. The purpose of this study was to identify risks, assess and determine the acceptance of risk, determine the dominant risk and mitigation actions and risk ownership for the dominant risk. The research was conducted in the Irrigation Areas (IA) of Cangi, Bunyuh, and Baru Kedokan with a combination method (quantitative and qualitative descriptive). The data collection was done by distributing questionnaires to respondents directly involved in the project implementation. The number of respondents was 20 people and selected by purposive sampling. The results showed identified risks of 36 risks with 14 risks of previous research outcomes and 22 risks from brainstorming results. The risk assessment and acceptance results were categorized as undesirable 52.78%, acceptable 33.33%, negligible 13.89%, and no risk was found in the category of unacceptable. Mitigation was conducted on the undesirable risks by making changes to the initial design plan in accordance with the field conditions, intensifying the implementation of the supervision in the field and carrying out the work in accordance with the operational standards and procedures contained in the contract. The ownership of risk was allocated to the parties involved in the project implementation including job owners 8 risks, supervisory consultants 9 risks, contractors 16 risks and farmer community 1 risk. The undesirable risk should be the concern of the parties involved in the project so that the final results of the work were in accordance with quality, cost, and time planned.

Abstract

Badan Penanggulangan Bencana Daerah Provinsi Bali pada tahun 2013 menyatakan bahwa beberapa wilayah Denpasar terendam banjir karena tingginya curah hujan pada daerah pemukiman sehingga terjadi genangan di beberapa area. Dampak kejadian banjir dapat dikurangi dengan membangun sumur resapan. Sumur resapan mampu menurunkan debit dan limpasan hujan dengan cara meningkatkan kapasitas infiltrasi di daerah aliran sungai. Perencanaan sumur resapan dianalisis dengan menerapkan remote sensing pada DAS Badung yang terdapat di wilayah Denpasar. Selanjutnya dilakukan perhitungan banjir dengan software HEC-HMS dan perencanaan sumur resapan berdasarkan SNI 03-2453-2002. Hasil analisis sumur resapan pada sub DAS Badung dapat menurunkan debit banjir kala ulang 50 tahun sampai 50,70% dan volume limpasan banjir 74,09%. sehingga penerapan pemanenan air hujan dengan sumur resapan dapat dijadikan salah satu referensi sebagai bentuk penerapan konservasi sumber daya air dalam upaya penurunan risiko bencana banjir di Kota Denpasar.
