Abstract

ABSTRAK Remedial work project (RWP) adalah suatu proyek konstruksi yang bertujuan untuk merehabilitasi bendungan yang terdiri dari perencanaan dan pemeliharaan serta pemantauan untuk mengurangi resiko kegagalan bendungan. Penelitian ini bertujuan untuk menganalisis implementasi remedial work project (RWP) pada Bendungan Jambu, Bendungan Lanangga, Bendungan Sanggupasante, Bendungan Kesi, Bendungan Woro, Bendungan Tolotangga, Bendungan Paradokanca, dan Bendungan Sumi dari penurunan resiko kegagalan bendungan. Efektifitas resiko kegagalan bendungan dapat diketahui dengan membandingkan tingkat resiko eksisting bendungan dengan tingkat resiko setelah dilakukan remedial work project (RWP). Dalam penelitian ini, metode yang digunakan dalam penilaian tingkat resiko menggunakan metode modifikasi ICOLD. Pada metode modifikasi ICOLD, penilaian tidak hanya fokus pada karakteristik bendungan saja melainkan tentang analisis evakuasi, kerusakan di hulu dan hilir, serta resiko kegagalan bendungan. Hasil analisa efektifitas akan dihubungkan dengan anggaran yang diberikan terhadap masing-masing bendungan yang kemudian selanjutnya di uji tingkat sensitifitasnya terhadap penurunan resiko. Penyebaran kuesioner juga dilakukan dalam penelitian ini yang bertujuan untuk mengetahui tingkat penilaian dari tenaga ahli terhadap implementasi operasi dan pemeliharaan bendungan. Hasil penelitian ini menunjukkan bahwa remedial work project (RWP) sangat efektif dalam menurunkan resiko kegagalan bendungan dengan rata-rata presentasi penurunan sebesar 24,58%. Alokasi anggaran yang diberikan di setiap bendungan berbedabeda karena karakteristik setiap bendungan berbeda-beda pula. Analisis sensitivitas menunjukkan bahwa semakin besar anggaran yang diberikan, maka semakin rendah tingkat resiko sehingga dapat diartikan bahwa jumlah anggaran yang diberikan sangat berpengaruh dalam menurunkan resiko bendungan. Pada analisis kuesioner dilakukan uji validasi yang menunjukkan bahwa nilai Rhitung > Rtabel, artinya kuesioner yang digunakan dalam penelitian ini dianggap valid. Dan uji reliabilitas menunjukkan nilai cronbach’s alpha > 0.70 , artinya tingkat pengukuran dalam kuesioner yang disebar memiliki konsistensi yang tinggi. Kata Kunci: Anggaran, Efektifitas, RWP, Sensitivitas. ABSTRAK Remedial work project (RWP) is a construction project that aims to rehabilitate a dam which consists of planning, maintenance and monitoring to reduce the risk of dam failure. This research aims to analyze the implementation of the remedial work project (RWP) at Jambu Dam, Lanangga Dam, Sanggupasante Dam, Kesi Dam, Woro Dam, Tolotangga Dam, Paradokanca Dam, and Sumi Dam in order to reduce the risk of dam failure. The effectiveness of the risk of dam failure can be determined by comparing the existing risk level of the dam with the risk level after the remedial work project (RWP) has been carried out. In this research, the method used to assess the level of risk uses the modified ICOLD method. In the ICOLD modification method, the assessment does not only focus on dam characteristics but also on evacuation analysis, upstream and downstream damage, and the risk of dam failure. The results of the effectiveness analysis will be linked to the budget allocated to each dam which will then be tested for its level of sensitivity to risk reduction. Questionnaires were also distributed in this research which aimed to determine the level of assessment of experts regarding the implementation of dam operations and maintenance. The results of this research show that the remedial work project (RWP) is very effective in reducing the risk of dam failure with an average reduction percentage of 24.58%. The budget allocation given to each dam is different because the characteristics of each dam are different. Sensitivity analysis shows that the larger the budget provided, the lower the level of risk, so it can be interpreted that the amount of budget provided is very influential in reducing dam risk. In the questionnaire analysis, a validation test was carried out which showed that the value of Rcount > Rtable, meaning that the questionnaire used in this research was considered valid. And the reliability test shows that the Cronbach's alpha value is > 0.70, meaning that the level of measurement in the questionnaire distributed has high consistency. Keywords: Budget, Effectiveness, RWP, Sensitivity.
