Abstract

The change of global climate influences the temperature, relative humidity, sunlight time, wind rate, rain rate, and river debit. The higher intensity of rain rate after the change of climate influences the fluctuation of river debit in rainy or dry season. Flood and dryness are natural occasions, which are usually occurring. Sutami Reservoir is functioned to retain water excess from rain and river debit from Brantas River, which in the future it would be stored. River debit is used to fulfill water need in dry season. Therefore, to face the extreme effect, there is needed management planning of reservoir operation managed well and optimally. Methodology used in climate change analysis toward operation model of Sutami Reservoir is Stochastic Dynamic Program and it is obtained a policy system of operation model output before and after climate change. Based on the result of analysis, it shows that there is climate change in Sutami Reservoir where it is signed that optimally reservoir output is changed. In the table of optimally reservoir output shows that before climate change the output policy is still in good condition while after it, the output policy is change where there is any displacement of wet season and dry season in which it causes the debit to Sutami Reservoir changed from what had been expected.Key words: climate change, reservoir operation model, stochastic dynamic program

Abstract

Kawasan padat penduduk Kelurahan Naikoten I, Kecamatan Oebobo, Kota Kupang setiap terjadi hujan dengan intensitas yang cukup tinggi selalu terjadi banjir/genangan air. Hal tersebut terjadi hampir di semua jalan/gang terutama di ruas Jalan Soeharto, Pasar Inpres Naikoten, depan SMU Kriten Nikoten dan Jalan Untung Suropati. Genangan disebabkan hampir semua permukaan tanah tertutup dengan lapisan kedap air, kesadaran masyarakat yang minim serta sebagian jalan/gang tidak memiliki saluran drainase. Studi dilakukan di Wilayah DPS Drainase Dendeng dan Merdeka, Kelurahan Naikoten I. Hasil studi menunjukkan besarnya debit rencana sistem DPS Drainase Dendeng dan Merdeka untuk kala ulang lima tahun masing-masing sebesar 24,017 m3/dt dan 4,775 m3/dt. Terdapat 9 saluran yang tidak mampu menampung debit rencana pada DPS Drainase Dendeng dan 8 saluran pada DPS Drainase Merdeka. Beberapa penyebab terjadinya saluran yang tidak mampu menampung debit rencana yaitu kurang terawat dan terdapatnya sampah pada saluran drainase.Upaya penanganan pada beberapa saluran yang tidak mampu menampung debit rencana yaitu dengan mendesain ulang dimensi saluran dan merencanakan kolam penampung. Selain penanganan tersebut dilakukan pula rekomendasi penanganan secara menyeluruh mengenai kebijakan-kebijakan pemerintah daerah yang melibatkan masyarakat setempat dan mengarah kepada pemberdayaan masyarakat dalam memelihara saluran drainase, pembangunan sumur resapan pada setiap rumah, serta izin dalam pendirian bangunan.Kata Kunci : Sistem Drainase, Genangan, Konservasi Air

Abstract

Pesatnya perkembangan industri tambak di indonesia sejak 1990, diiringi dengan berkurangnya lahan bakau. Hal ini memicu terjadinya kerusakan lingkungan akibat polusi kegiatan tambak. Air limbah buangan tambak terbukti mengandung bahan pencemar sisa pakan, mikroorganisme dan bibit penyakit. Metode yang akan digunakan dalam perencanaan unit pengolahan limbah  tambak udang adalah metode biofilter secara anaerobik dan aerobik. Tujuan dari penelitian ini adalah mengetahui kualitas air limbah tambak sebagai dasar penentuan rancangan instalasi pengolahan air limbah pada Tambak udang, sehingga diharapkan air limbah yang akan dikembalikan menuju badan perairan sesuai dengan baku mutu, dan nantinya akan mengurangi pencemaran di Pantai Mayangan, Kota Probolinggo. Sebelum melewati tahapan proses pengolahan limbah, kandungan BOD, TSS, fosfat, H2S dan amonia pada sampel air tidak memenuhi baku mutu limbah tambak udang. Hasil dari pengolahan limbah ini terbukti sangat efektif. Didapatkan nilai-nilai kandungan polutan air limbah, dapat berkurang secara signifikan. Contohnya parameter BOD pada limbah. Sebelumnya didapati kandungan BOD pada sampel limbah air tambak sebesar 571,72 miligram per liter sampel. Nilai ini melebihi ambang baku mutu yang ditetapkan yaitu kurang atau sama dengan 45 miligram per liter air limbah. Setelah melewati tahapan pengolahan air limbah, dihasilkan nilai BOD yang rendah dan memenuhi kriteria, sebesar 20,582 mg/l. The rapid development of the ponds industry in Indonesia since 1990, accompanied by a reduction in mangrove land. This triggers environmental damage due to pollution of pond activities. Pond wastewater is proven to contain contaminants left over from feed, microorganisms and disease germs. The method to be used in planning the shrimp pond waste treatment unit is an anaerobic and aerobic biofilter method. The purpose of this study is to determine the quality of pond wastewater as a basis for determining the design of wastewater treatment plants in shrimp ponds, so that it is expected that wastewater will be returned to the water body in accordance with quality standards, and will later reduce pollution in Mayangan Beach, Probolinggo City. Before going through the stages of the waste treatment process, the content of BOD, TSS, phosphate, H2S and ammonia in water samples does not meet the quality standards of shrimp pond waste. The results of this waste treatment have proven to be very effective. Obtained values ​​of wastewater pollutant content, can be reduced significantly. For example BOD parameters in waste. Previously found BOD content in pond water waste samples worth 571.72 milligrams per liter of sample. This value exceeds the established quality standard that is less or equal to 45 milligrams per liter of wastewater. After passing through the wastewater treatment stage, a low BOD value is produced and fulfills the criteria, valued at 20,582 mg/l.

Abstract

Permasalahan genangan akibat hujan dengan intensitas tinggi menjadi masalah utama khususnya di kawasan perkotaan dengan kepadatan penduduk yang tinggi. Terjadinya alih fungsi lahan dari kawasan resapan menjadi kawasan kedap air menjadi penyebab utama  meningkatnya limpasan permukaan yang mendorong terjadinya banjir. Penelitian ini bertujuan untuk menganalisa sebaran limpasan permukaan secara spasial dengan variasi tahun penggunaan lahan dan menganalisa fungsionalitas jaringan drainase dalam mengurangi genangan yang terjadi.Penelitian ini mengambil lokasi di Sub DAS Brantas, Kecamatan Klojen, Kota Malang. Analisa sebaran limpasan permukaan dilakukan dengan menggunakan model KINEROS yang diintegrasikan dengan perangkat lunak ArcView GIS 3.3. Masukan dari model KINEROS adalah peta tata guna lahan, peta jenis tanah, peta topografi, dan data hujan. Nilai debit limpasan permukaan yang dihasilkan model KINEROS (Qh) selanjutnya ditambahkan debit air buangan (Qk) untuk mendapatkan debit rencana (Qr). Berikutnya dilakukan analisa fungsionalitas jaringan drainase di lokasi penelitian dalam mengurangi limpasan.Hasil studi menunjukkan limpasan yang terjadi meningkat seiring dengan semakin meningkatnya luasan kawasan kedap air. Tinggi limpasan permukaan tertinggi dihasilkan tahun 2010 setinggi 142,76mm yang terjadi di Kelurahan Penanggungan. Besar limpasan yang tereduksi oleh saluran drainase yaitu sebesar 51,637  m3/dtk. Hasil evaluasi kemampuan saluran drainase menunjukkan bahwa masih terdapat beberapa saluran yang tidak mampu menampung debit limpasan permukaan sehingga menimbulkan genangan.
