Abstract

Daerah aliran sungai Way Batu Merah terdapat bangunan sabo dam untuk mengendalikan atau kontrol tinggi muka air dan pergerakan sedimen pada saat aliran debris. Berdasarkan tinjauan dan pengamatan kondisi bangunan Sabo Dam Air Kuning (Goa Maria)-Karang Panjang yang terdapat pada daerah aliran sungai Way Batu Merah, ternyata bangunan sabo dam ini tidak lagi berfungsi seutuhnya, dikarenakan terjadi penimbunan sedimen pada area tampungan yang sudah melebihi kapasitas dari bangunan itu sendiri. Kondisi ini berpengaruh terhadap fungsi utama dari bangunan sabo dam, yaitu sebagai pengendali sedimen, sehingga perlu untuk melakukan evaluasi kinerja bangunan sabo dam. Untuk mengevaluasi bagunan sab sam digunakan metode pengamatan mengunakan tabel evaluasi kinerja, serta metode USLE (Universal Soil Loss Equation). Metode USLE mempertimbangkan pengunaan tanah di daerah penilitian, sehingga metode ini dapat diandalkan sebagai analisis dari jumlah sedimen. Hasil penelitian ini menunjukan bahwa . Tingkat kerusakan pada bangunan sabo dam sebesar 17%, Talud 32%, dan untuk Tanggul 32%. Dari analisis USLE didapat volume sediment potensial sabo dam sebesar 33,83 m3. Dari hasil perhitungan di dapat kapasitas bangunan Sabo Dam Air Kuning Goa Maria Karang Panjang Ambon sebesar 15,3 m3.maka bangunan Sabo Dam tersebut dinilai tidak mampu untuk menampung angkutan sedimen yang terjadi.

Abstract

The evaluation of irrigation network performance is essential to ascertain the status of these networks. This is governed by the Regulation of the Minister of PUPR No.12/PRT/M/2015 about the Exploitation and Maintenance of Irrigation Networks. This study aims to assess the physical condition of the principal channel, its performance, and the availability of discharge. The physical condition and functionality of the Way Geren irrigation canal remain satisfactory. Channels 1 and 2 achieved an 89% presentation and a 77% capacity for discharge. The embankment height was sufficient to prevent runoff at 85% for both measurements. However, the implementation of repairs and maintenance received a presentation score of only 30% due to the lack of maintenance and repairs conducted on the channel. The performance evaluation of primary irrigation canals in the Way Geren irrigation region indicates a 67.5% rating of mediocre condition, necessitating maintenance of a reparative nature. This enhancement aims to rehabilitate the principal irrigation canal of the Way Geren irrigation region to improve its operational efficacy. Based on the Network Scheme for an area of 453 hectares, with a designated discharge (Q) of 0.802 m³/sec, a wet cross-sectional area (A) of 0.863 m², a flow velocity (V) of 0.158 m/s, and a flowing discharge (Q) of 0.136 m³/sec at a door opening of 0.09 m.

Abstract

Investments that enhance a nation's infrastructure include water structures, such as the Wae Leman Dam in Indonesia. The Wae Leman Dam, serving an area of 2500 hectares, is situated on the Wae Leman River in Buru Regency, Maluku Province. This extensive region necessitates optimal circumstances for dam construction and the upkeep of irrigation systems in the Wae Leman irrigation basin, particularly for this dam project. The Wae Leman Dam has not undergone maintenance since its construction in 2015, with plans for maintenance scheduled in 2023. Consequently, it is essential to perform a performance analysis of the Wae Leman dam to assess its physical condition, efficacy, and functionality at present. This study employs references from the Regulation of the Minister of Public Works and Public Housing Number 12/PRT/M/2015 regarding Irrigation Exploitation and Maintenance, which has been adapted into the Irrigation System Performance Index (IKSI) method to facilitate the evaluation of the condition and functionality of dam structures. The dam performance index assessment yielded a weight of 11.36%, which corresponds to 87.3% of the maximum weight of 13% for the Wae Leman Dam performance evaluation. This number signifies that the performance of the primary building system (dam) is satisfactory; the recommendations for re-optimizing the dam's function include repairs, routine maintenance, and periodic maintenance activities.
