Daftar Isi:
- Yamdena and Selaru Islands grouped in the cluster of Tanimbar Archipelago, West Southeast of Maluku. In this area, identified some water resources such as springs, dug wells, and rivers. Water quality study in this area is carried out in order to utilize water resources to support regional development of the small islands in Tanimbar Archipelago. The assessment of groundwater chemistry typology is performed to springs that potential to be developed, such as Wetemar, Wemomolin, Wesori, and Wetotote by using a classification method in Piper Trilinier Diagram. The assessment of water quality status and feasibility of utilization is performed to all type of water resources that has been identified and potential to be utilized. Physical and chemical parameters of water are obtained from direct measurement in field and laboratory testing. Analysis and evaluation results indicate that the typology of springs in Yamdena and Selaru Islands came from groundwater flow in the upper zone which was influenced by surface water. According to the laboratory testing results, almost water resources in Yamdena and Selaru Islands have not met yet the quality standard. The final results of this research are expected to be helpful for the further water utilization which is directed to make a sustainable utilization.
- Pulau Yamdena dan Selaru termasuk ke dalam gugusan Kepulauan Tanimbar, Maluku Tenggara Barat. Di wilayah ini telah teridentifikasi sumber – sumber air seperti mata air, sumur gali, dan sungai. Penelitian kualitas air di wilayah ini dilaksanakan dalam rangka pemanfaatan sumber – sumber air guna mendukung pengembangan wilayah pulau-pulau kecil di Kepulauan Tanimbar. Penilaian tipologi kimia air tanah dilakukan terhadap mata air yang berpotensi untuk dikembangkan, seperti mata air Wetemar, Wemomolin, Wesori, dan Wetotote dengan menggunakan metode klasifikasi pada Diagram Piper Trilinier. Penilaian status mutu air dan kelayakan pemanfaatan dilakukan terhadap semua jenis sumber air yang teridentifikasi dan potensial untuk dimanfaatkan. Data parameter fisika dan kimia air diperoleh dari pengukuran langsung di lapangandan pengujian di laboratorium. Hasil analisis dan evaluasi menunjukkan bahwa tipologi mata air di Pulau Yamdena dan Pulau Selaru berasal dari aliran air tanah zona atas yang dipengaruhi oleh air permukaan. Berdasarkan hasil uji Laboratorium hampir semua sumber air di Pulau Yamdena dan Pulau Selaru belum memenuhi baku mutu yang digunakan. Hasil akhir dari penelitian ini diharapkan dapat membantu pendayagunaan air selanjutnya yang diarahkan untuk mewujudkan pengembangan pemanfaatan yang berkelanjutan.
