Abstract

Wastewater from the outlet of hospital's Wastewater Treatment Plant (WWTP) is expected to be used for watering plants as an effort to water use efficiently. To answer this assumption, this research was carried out to examine the effects of hospital wastewater as a plant growth medium on the accumulation of pollutants in papaya (Carica papaya) leaves and fruit. Local papaya seeds were grown on the land around the hospital's WWTP and the plants were watered every day with wastewater. Plants were well cared for without adding other additives as fertilizer and their growth was observed. After 8 months of treatment, the fruits and leaves of plants were harvested and destructed using HNO3 and H2SO4 to measure the heavy metal content using the Atomic Absorption Spectrophotometer, Shimadzu A630. Results showed that when wastewater was used as a growth medium, metals Hg, Cd, and Pb were found to accumulate in papaya fruit with a concentration of 0.179; 0.582; and 2,327 mg/kg, while other metals such as Cr and As were not found to accumulate in papaya fruit. Metal accumulation was also found in papaya leaves with Hg content of 0.739 mg/kg and Cd of 0.582 mg/kg, while others metals Cr, Pb, and As were not found in the papaya leaves. These results indicate that the main source of heavy metal accumulation in papaya plants came from wastewater from the WWTP outlet containing heavy metals.

Abstract

AbstractThis study aimed to determine the priority of rehabilitation and maintenance of the Jeuram irrigation network in Nagan Raya Regency using the Analytical Hierarchy Process (AHP) method. Damage identification was carried out through field surveys on irrigation networks in Blang Ara Village and Cot Gud Village, which recorded moderate damage as the most dominant. The assessment of rehabilitation priorities was based on four criteria: patching leaks, vegetation control, channel rehabilitation, and channel cleaning, with patching leaks having the highest weight (0.634). The evaluation results showed that Minor Structural Repair was the top priority alternative with the highest performance score (2.05), followed by Irrigation Channel Edge Strengthening (1.95) and Irrigation Dam Reconstruction (1.80). The repair budget showed a dominance of concrete work, reflecting the need to strengthen the physical structure of the channel. The total budget required for Blang Ara Village is Rp33,291,247.24, while for Cot Gud Village it is Rp31,374,880.50. The AHP-based approach provides an objective assessment in determining rehabilitation priorities by considering the level of damage, budget efficiency, and its impact on agricultural productivity. The results of this study provide strategic guidance for more efficient and sustainable irrigation network management, supporting increased agricultural productivity, and ensuring the sustainability of irrigation systems for future needs.Keywords:Analytical hierarchy process (AHP); irrigation maintenance costs; irrigation infrastructure; irrigation repair prioritiesAbstrakPenelitian ini bertujuan untuk menentukan prioritas rehabilitasi dan pemeliharaan jaringan irigasi Jeuram di Kabupaten Nagan Raya menggunakan metode analytical hierarchy process (AHP). Berdasarkan hasil observasi lapangan, ditemukan berbagai permasalahan fisik pada jaringan irigasi, antara lain retaknya dinding saluran, pertumbuhan vegetasi liar pada dinding dan dasar saluran, penutup saluran yang rusak dan berlubang, serta sedimentasi dan penumpukan sampah yang menghambat aliran air. Selain itu, bangunan pelengkap irigasi berada dalam kondisi tidak memadai secara fungsi, sehingga tidak mampu mendukung distribusi air secara optimal ke lahan pertanian. Kondisi tersebut diperparah oleh keterbatasan sumber daya manusia dalam kegiatan pemeliharaan dan operasional jaringan, menyebabkan banyak kerusakan yang tidak segera tertangani. Analisis kondisi menunjukkan bahwa tingkat kerusakan sedang merupakan kategori dominan pada jaringan irigasi di Desa Blang Ara dan Desa Cot Gud. Penilaian prioritas rehabilitasi dilakukan berdasarkan empat kriteria, yaitu penambalan kebocoran, pengendalian vegetasi, rehabilitasi saluran, dan pembersihan saluran. Hasil analisis AHP menunjukkan bahwa penambalan kebocoran memiliki bobot tertinggi (0,634), menandakan aspek ini sebagai faktor paling krusial dalam peningkatan kinerja jaringan. Alternatif perbaikan struktural minor menjadi prioritas utama dengan skor kinerja tertinggi (2,05), diikuti oleh penguatan tepi saluran irigasi (1,95) dan rekonstruksi bendungan irigasi (1,80). Total anggaran yang dibutuhkan mencapai Rp. 33.291.247,24 untuk Desa Blang Ara dan Rp. 31.374.880,50 untuk Desa Cot Gud, dengan dominasi pekerjaan beton. Pendekatan AHP terbukti memberikan penilaian objektif dan efisien, serta menjadi dasar strategis dalam pengelolaan jaringan irigasi yang berkelanjutan dan mendukung peningkatan produktivitas pertanian.    Kata Kunci:Analytical hierarchy process (AHP); biaya pemeliharaan irigasi; infrastruktur irigasi prioritas perbaikan irigasi
