Keterbatasan air pada lahan sangat berdampak terhadap pertumbuhan dan perkembangan tanaman budidaya. Permasalahan keterbatasan air dapat diatasi dengan mengusahakan ketersediaan air setiap musim tanam, dengan menerapkan suatu teknologi irigasi yang mampu memberikan air secara efektif dan efisien. Penerapan irigasi cincin dengan emitter berbentuk cincin yang dilapisi dengan bahan porus dari bahan tekstil. Bahan porus berperan penting dalam mengatur aliran debit air melalui emitter, yang berdampak signifikan pada efisiensi keseluruhan dari sistem irigasi cincin. Penelitian ini bertujuan untuk mengetahui kinerja emitter cincin pada sistem irigasi cincin dengan menggunakan tiga jenis bahan porus. Penelitian ini dilaksanakan pada bulan Februari hingga Agustus 2022 berlokasi di lahan percobaan Fakultas Pertanian, Universitas Borneo Tarakan. Penelitian ini terdiri atas beberapa tahapan yaitu pengaplikasian sistem irigasi cincin, penerapan emitter cincin, penggunaan bahan porus emitter dan uji kinerja emitter cincin. Penelitian ini terdiri dari beberapa parameter yaitu debit, koefisien keseragaman (Cu), distribusi keseragaman (Du), efisiensi penyimpanan (Es) dan efisiensi penggunaan (Eap). Hasil penelitian menunjukkan bahwa nilai debit tertinggi diperoleh pada bahan parasut yaitu sebesar 107,38 ml/menit. Nilai Cu dan Du pada ketiga bahan porus termasuk dalam kategori baik karena memiliki nilai > 80%. Nilai Es dan Eap pada ketiga bahan porus termasuk dalam kategori tidak layak karena memiliki nilai < 50%. Berdasarkan hasil pengujian, bahan oscar memiliki nilai tertinggi diantara ketiga jenis bahan dengan nilai Cu = 89,79%, Du = 83,76%, Es = 49,75% dan Eap = 44,67%

A shortage of water on land has a significant impact on the growth and development of cultivated plants. The limited water supply can be handled by using an irrigation technique that can provide water effectively and efficiently during the growth. season Ring irrigation is used with ring-shaped emitters which are conted with a porous substance made of textile The porous material plays an important role in regulating the flow of water through the emitter, which has a significant impact on the overall efficiency of the ring irrigation system. This study aims to determine the performance of ring emitters on ring irrigation systems using three types of porous materials. This research was conducted from February to August 2022 at the experimental field of the Faculty of Agriculture, University of Bomco Tarakan This research consists of four stages, ring irrigation system application, ring emitter application, the use of emitter porous materials, and ring emitter performance Testing The parameters that were investigated in the study were discharge, uniformity coefficient (Cu), uniformity distribution (Du), struge efficiency (Es), and efficiency of use (Eap) According to the research's findings, the parachute material had the highest debit value of 107 38 ml/minute The Cu and Du values in the three porous materials are categorized as good because they have values > 80% The Es and Eap values of the three porous materials fall into the infeasible category because they have values < 50% Based on the test results, Oscar material has the highest value among the three types of materials with Cu-89.79%, Du-83.76% Es-49.75%, and Fap=44.67 Keywords: Performance Test, Ring Irrigation, Porous Material
