Penilaian dan Evaluasi Kinerja Bangunan Embung di Kecamatan Janapria Kabupaten Lombok Tengah

Abstract

Abstract: Small reservoirs are important water resources infrastructure that serve as water storage facilities to meet irrigation, conservation, and community water needs, particularly during the dry season. As these structures age, their physical condition may deteriorate, necessitating periodic evaluation to determine their structural condition and the effectiveness of their utilization. This study aims to assess the physical condition and evaluate the benefits of four small reservoirs in Janapria District, Central Lombok Regency, namely Tasik-Asik, Kuangsampi, Pendem/Suntiang, and Danasari Reservoirs. The study employed a quantitative approach through field observations based on physical condition inspection forms and reservoir benefit assessment forms in accordance with operation and maintenance guidelines. The results showed that the physical condition scores of the four reservoirs ranged from 83.10% to 87.25%, while their benefit scores ranged from 71.90% to 89.90%. Tasik-Asik Reservoir obtained a physical condition score of 83.10%, categorized as lightly damaged, and a benefit score of 89.90%, categorized as good. Kuangsampi Reservoir obtained a physical condition score of 84.65%, categorized as lightly damaged, and a benefit score of 84.30%, categorized as good. Pendem/Suntiang Reservoir obtained a physical condition score of 86.65%, categorized as lightly damaged, and a benefit score of 71.90%, categorized as fair. Danasari Reservoir obtained a physical condition score of 87.25%, categorized as lightly damaged, and a benefit score of 82.30%, categorized as good. The highest physical condition score was recorded for Danasari Reservoir, while the highest benefit score was recorded for Tasik-Asik Reservoir. Overall, all four reservoirs remain in serviceable condition and provide good benefits as water storage facilities. However, regular operation and maintenance activities are required to maintain structural performance and ensure the sustainability of their utilization.

Abstrak: Embung merupakan salah satu infrastruktur sumber daya air yang berfungsi sebagai penyedia cadangan air untuk memenuhi kebutuhan irigasi, konservasi, dan masyarakat, terutama pada musim kemarau. Seiring bertambahnya umur bangunan, kondisi fisik embung dapat mengalami penurunan sehingga diperlukan evaluasi secara berkala untuk mengetahui tingkat kelayakan bangunan dan efektivitas pemanfaatannya. Penelitian ini bertujuan menilai kondisi fisik dan mengevaluasi manfaat empat embung di Kecamatan Janapria, Kabupaten Lombok Tengah, yaitu Embung Tasik-Asik, Kuangsampi, Pendem/Suntiang, dan Danasari. Metode penelitian menggunakan pendekatan kuantitatif melalui observasi lapangan berdasarkan formulir inspeksi kondisi fisik dan formulir penilaian manfaat embung sesuai pedoman operasi dan pemeliharaan. Hasil penelitian menunjukkan bahwa kondisi fisik keempat embung berada pada rentang 83,10%–87,25%, sedangkan nilai manfaat berada pada rentang 71,90%–89,90%. Embung Tasik-Asik memperoleh nilai kondisi fisik 83,10% (rusak ringan) dan manfaat 89,90% (baik). Embung Kuangsampi memperoleh kondisi fisik 84,65% (rusak ringan) dan manfaat 84,30% (baik). Embung Pendem/Suntiang memperoleh nilai kondisi fisik 86,65% (rusak ringan) dan manfaat 71,90% (cukup). Embung Danasari memperoleh kondisi fisik 87,25% (rusak ringan) dan manfaat 82,30% (baik). Nilai kondisi fisik tertinggi terdapat pada Embung Danasari, sedangkan nilai manfaat tertinggi terdapat pada Embung Tasik-Asik. Secara keseluruhan, seluruh embung masih berada pada kondisi layak dan manfaat baik serta berfungsi sebagai penyedia air. Namun, diperlukan kegiatan operasi dan pemeliharaan secara berkala untuk mempertahankan kinerja bangunan dan keberlanjutan pemanfaatannya.
