Abstract

Perumnas Made kabupaten Lamongan di kenal sebagai salah satu daerah yang sering dilanda banjir ketika musim penghujan datang dan kekeringan ketika musim kemarau datang. Dengan perkembangan yang sangat pesat, yang meliputi jumlah penduduk dan ekonomi dari wilayah urban metropolitan Gerbang kertosusila. Salah satu faktor yang mendatangkan bencana alam di area yang mereka tempati adalah yang akan kurangnya kesadaran mengenai menjaga lingkungan sekitar. Karena itu sangat penting melaksanakan konservasi air dalam rangka menjaga kelestarian lingkunan terutama air bersih. Tujuan penelitian ini adalah menentukan jumlah dan titik sumur resapan yang di perlukan di wilayah perumnas Made. Metode penelitian kuantitatif dengan pengumpulan data hujan selama periode 10 tahun terakhir dan survey dengan alat ukur dan GPS. Berdasarkan data dari survei tersebut kemudian akan dianalisa dengan menggunakan metode analisa faktor. Kemudian hasil dari perhitungan tersebut dapat di tentukan kebutuhan sumur resapan di Perumahan Perumas Made yang diperoleh sumur dengan diameter 1,2 m dengan kedalaman 1,5 m, lalu didapatkan hasil debit banjir rencana terbesar yang terjadi pada kala ulang 10 tahun yaitudengan debit 1,442  dan debit air limbah rumah tangga sebesar 0,939  pada periode kala ulang 10 tahun. Kata Kunci: Perumnas Made, Konservasi Air, Sumur Resapan.

Abstract

ITS Surabaya Student Dormitory Building uses PDAM clean water services and is also equipped with a fire extinguishing installation whose distribution network system uses clean water. As students' needs increase, their need for clean water will also increase. And because of this, this building often experiences problems distributing clean water during peak usage hours due to simultaneous use, there is a decrease in the flow of each unit of piping equipment due to uneven installation of the clean water distribution system. Therefore, the distribution system in pipes requires special handling which often experiences problems in terms of quantity, pressure and continuity of water. The aim of this research is to analyze the magnitude of energy loss in the plumbing pipe network in the ITS Surabaya Dormitory Building, and also to analyze the causes of closed pipes experiencing energy loss. At which point the energy loss is highest, so is the remaining energy at the last pipeline node. The method used in this research is a quantitative method by analyzing the condition of the existing pipe network in clean water installations and fire extinguishing installations in terms of pipe dimensions, pipe length and reservoir elevation which will then be carried out by running tests with the program to find out how much The large energy losses that occur in plumbing pipe networks are assisted by a simulation program using Epanet 2.2. From the results of this research, there are several conclusions that the results of the analysis of the Clean Water pipe network of the ITS Surabaya Student Dormitory Building for clean water installations have the highest velocity (Velocity) of 0.2 m/s in pipe 15 on the 1st Floor, and the sprinkler pipe has a velocity (Velocity). ). ) the highest is 0.08 m/s on pipe 01 Floor 2. There are still many pipes whose speed is less than 0.1 m/s, which means the pipe speed in the network does not meet the design criteria. And for the pressure of the clean water pipe network and sprinklers at all node points with a value of ≥0.5 bar (according to planning standards). Based on the results of running unit headloss, the clean water pipe network and sprinklers have a value of <10 m/Km (according to planning standards) and no pipes experience negative pressure or pressure drop.

Abstract

Kegiatan penilaian angka kebutuhan operasional dalam rangka operasi dan pemeliharaan sarana air tanah merupakan kegiatan yang dilaksanakan untuk mendata kondisi saat ini dan mendata kerusakan pada bangunan Jaringan Irigasi Air Tanah sekaligus inventarisasi prasarana air tanah untuk mewujudkan kemanfaatan irigasi secara berkesinambungan. Maka untuk itu perlu dilakukan kegiatan penilaian angka kebutuhan operasional sarana air tanah dalam kegiatan Operasi dan Pemeliharaan guna menjaga kinerja sarana air tanah. Tujuan penelitian ini ialah untuk Menganalisa gambaran umum lokasi pekerjaan, data teknis, kondisi fisik dan sarana kinerja serta Angka Kebutuhan Nyata Operasi dan Pemeliharaan JIAT SDPB 019 yang ada di Kabupaten Probolinggo. Dari hasil Analisa perhitungan menggunakan metode AKNOP didapatkan didapat bobot penilaian prasarana utama 34,98%, bobot penilaian produktivitas tanam sebesar 7,75%, bobot penilaian sarana penunjang sebesar 4,40% dan bobot penilaian organisasi personalia sebesar 10,44%. dan nilai angka kebutuhan nyata (AKNOP) untuk sarana JIAT SDPB 019 di kabupaten Probolinngo yaitu sebesar Rp. 151.505.787,00
