Abstract

Waduk Lahor terletak pada desa Karangkates, Kecamatan Sumberpucung, Kabupaten Malang, Provinsi Jawa Timur. Waduk Lahor mulai beroperasi sejak tahun 1977 dengan usia rencana selama 50 tahun sehingga diharapkan dapat beroperasi hingga tahun 2027, masalah utama yang dihadapi dalam pengelolaan waduk adalah bagaimana menjaga agar umur layanan waduk dapat sesuai dengan yang direncanakan dikarenakan adanya sedimen yang mengendap pada dasar waduk dan seiring waktu akan semakin mengurangi tampungan efektif waduk., dan pada tahun 2015 tampungan mati Waduk Lahor menyisakan kapasitas 2.517.357,31 m3. Dari hasil studi didapatkan adanya keterkaitan antara debit sedimen (Qs) dengan debit inflow waduk (Qw) menggunakan model Regresi Berpangkat dengan fungsi Qs = 1,623.Qs0,72, pada pengujian  model didapatkan bahwa model stokastik Thomas-Fiering lebih representatif untuk pembangkitan data sintetik daripada model Rantai Markov dikarenakan memiliki simpangan lebih kecik dengan nilai RMSE 4,19 m3/detik dan nilai MAE 2,92 m3/detik. Dari hasil bangkitan data sintetik sepanjang usia rencana dan persamaan regresi berpangkat didapatkan volume sedimen tahun 2015 – 2027 dengan nilai trap efisiensi 88% sejumlah 1.822.200,05 m3, sehingga pada tahun 2027 diprediksi tampungan mati hanya menyisakan kapasitas 695.159,26 m3 dan dapat disimpulkan bahwa Waduk Lahor dapat beroperasi hingga usia rencana

Abstract

Facilities and infrastructure play an important role in supporting the sustainability of educational institutions. The school is responsible for its management, including planning and maintenance. With adequate facilities, the teaching and learning process can take place effectively and efficiently. The research method used is qualitative research with a literature study approach, where the sources used are books and journals that are in accordance with the material being discussed. However, in reality, sometimes the standardization of school facilities and infrastructure is still lacking, causing a problem. The conclusion of this study is that well-maintained facilities and infrastructure in elementary schools and Islamic elementary schools can support effective learning, save repair costs, and shape student character. Good maintenance can create a comfortable learning environment and improve the image of the school
