Abstract

Rainwater is an abundant source of water, especially during the rainy season. But otherwise if it is not managed properly, it can lead to disasters, such as floods or landslides. Therefore it is very important to harness rainwater by doing the best way, ie by the rain harvesting and then infiltrating the water back into the ground. Many countries have shown good results in the use of rainwater for various purposes. Dominican Republic, Singapore, Japan, China, Thailand and Indonesia are 7 countries which have a lot of implementing rainwater utilization system very well. Rainwater can be used as a source of clean water to meet the drinking water needs. Artificial recharge for rain water lets the water goes to infiltrate back into the soil is a powerful effort to maintain and preserve the ground water potential. Besides, infiltration of rainwater into the soil also can prevent land subsidence. Because of the importance of rainwater management system, it should be included in the educational curriculum both for elementary to upper secondary level. Similarly, the obligation for proper implementation must also be supported by adequate rules or regulations. Keywords : Rainwater management, artificial recharge.

Abstract

Principle of zero delta Q policy is that a development should not  increase water discharge to drainage system. Policy of zero delta Q is apply to zone of recharge area and other zone which is not recharge area as well, because this area which is not as recharge area has contribute a great deal to local flood. Based on this therefore implemention of policy of zero delta Q is applied to urban area such as Jakarta. Activities proposed for Jakarta were: 1. Optimize use of water reservoir, pond and site; 2. Implementation of artificial recharge or could be combined with biopore; 3. Effective land use by provide open green areas; and 4. Normalization of drainage system. Keywords : policy, zero delta q, flood, artificial recharge, biopore, development

Abstract

Areas of Jakarta, Bogor, Tangerang and Bekasi (Greater Jakarta) is an area with high rainfall (2250 -2500 mm/year). The rain that falls in this region often cause flooding problems in the area of rice fields, settlements and even in downtown. Rain is a gift from God to be utilized to the maximum extent possible for everyday purposes. Rain Water Harvesting is an attempt to capture rainwater that falls on the roof. In this study, use of the roof area of about 300 -500 m2. Precipitation that falls on the roof is channeled and put into storage, by first filtering done to reduce the dirt. The volume of rain water storage for each location is 10 m3, medium intensity rain (15-20 mm/h), sufficient to meet the storage within a few hours. Rain Water Reservoir are equipped with water pump which has a capacity of 25 liters/minute, the water can be used for flushing toilets and spraying crops. If Rain Water Reservoir is full, water overflows into the Artificial recharge well. The results of analysis with Kostiokov calculation method used to calculate the infiltration rate of Artificial recharge well and calculate the cumulative volume of infiltration at the Artificial recharge well. Results of tests conducted are as follows: a). In Depok, the infiltration rate of Artificial Recharge Well is about 12 mm/minute and was relatively stable at 140 minute (2 mm/minute). It also has the ability to recharge  450 liters of water in 140 minutes. b). In South Jakarta, the infiltration rate of Artificial Recharge Well is about 11 mm/minute and was relatively stable at 160 minutes (2.5 mm/minute). Artificial Recharge Well has the ability to recharge  480 liters of water  in 160 minutes. c). In Bantarjati, Bogor,  Artificial Recharge Well have the highest capacity, namely 45 mm/minute and was relatively stable at 260 minutes (2.5 mm/minute). Artificial Recharge Well has the ability to recharge 1000 liters of water  in 150 minutes. Rain Water Harvesting Development Efforts and Artificial Recharge Well very useful to overcome inundation in residential areas, especially during heavy rain, because it can reduce the volume of surface water into the channel simultaneously. Keywords : Rain Water Harvesting, Infiltration, Artificial Recharge.

Abstract

Penggunaan air tanah sebagai sumber air bersih untuk digunakan sebagai air minum sering terkendala oleh kualitas air mengandung besi terlarut yang cukup tinggi. Kandungan zat besi diatas 0,3 ppm menyebabkan sumber air tersebut tidak layak digunakan sebagai sumber air baku air bersih dan untuk kandungan besi diatas 0,05 ppm menyebabkan sumber tersebut tidak layak digunakan sebagai sumber air minum.  Air baku dengan kualitas seperti itu sebaiknya dilakukan pengolahan terlebih dahulu.  Air tanah yang berasal dari daerah vulkanik aktif dengan batuannya banyak mengandung zat besi terutama dari daerah yang sering mengalami perendaman air seperti daerah bekas sawah atau bekas rawa. Proses kimiawi yang bekerja di wilayah ini tersebut pada umumnya adalah proses reduksi. Pada umumnya besi yang ada terlarut dalam air adalah sebagai Fe2+ atau Fe3+, dalam ikatan kimia sebagai Fe2O3, Fe(OH)2 Fe(OH)3 ataunFeSO4. Setelah dilakukan ekploitasi atau pengambilan air tanah dan air baku tersebut mengalami kontak langsung dengan udara, maka akan berwana kecoklatan, berbau amis seperti karat besi. Ada tiga cara penurunan zat besi dalam air yaitu dengan cara 1. Aerasi, 2. Sedimentasi dan 3. Filtrasi. Dalam percobaan ini proses penurunan zat besi dilakukan dengan cara aerasi yaitu dengan mengaplikasikan penggunaan gelembung mikro yang dihasilkan dari generator pembangkit gelembung mikro dan dengan filtrasi. Pembangkit gelembung micro ini dibangkitkan oleh pompa KTN Merk Nikuni menghasilkan gelembung udara dengan diameter 20 micron yang digunakan sebagai bahan oksidator untuk air baku mengandung besi. Setelah proses oksidasi berlangsung dalam periode waktu tertentu kemudian disaring dan diukur sisa kandungannya. Hasil percobaanadalah pada kandungan besi dalam air baku sebesar 1,16 ppm yang direaksikan dalam sebuah reactor maka efisiensi oksidasi dapat dicapai dengan baik dan berhasil menambah kelarutan oksigen dalam air sebesar 71-80 % dan menurunkan zat besi dalam air baku sampai mencapai 38-56 % pada pH 7. Kesimpulan yang dapat diambil melalui percobaan ini adalah bahwa generator gelembung mikro mampu digunakan sebagai sebuah cara untuk mengoksidasi zat besi terlarut dalam air baku dan dapat dimanfaatkan sebagai sebuah cara untuk meningkatkan kandungan oksigen terlarut air baku.Kata kunci: air tanah, zat besi terlarut, pembangkit gelembung mikro, oksidasi

Abstract

Salah satu sektor pembangunan di Indonesia yang tidak bebas dari ancaman perubahan iklim adalah sektor transportasi udara. Oleh karena, perlu disiapkan strategi adaptasi dampak perubahan iklim. Bandara Hasanuddin Makassar berpotensi terkena dampak peningkatan suhu permukaan, kelembaban udara dancurah hujan dalam sepuluh tahun terakhir. Jika melihat data emisi gas polutan (non-GRK) terlihat bahwa polusi udara belum menjadi ancaman nyata. Namun ancaman yang akan segera dialami adalah berubahnya beberapa parameter meteorologis seperti suhu permukaan, kelembaban dan intensitas curah hujan. Berdasarkan data pemantauan oleh otoritas bandara memperlihatkan untuk rentang waktu 10 tahun sejak 2003 hingga 2013, telah terjadi kenaikan suhu permukaan rata-rata sebesar 10C. Kenaikan suhu permukaan ini juga diikuti kenaikan kelembaban pada rentang waktu yang sama sebesar 5%. Perubahan ketiga komponen iklim ini akan memberi dampak pada sistem penerbangan sehubungan dengan fenomena perubahan iklim. Melalui analisis risiko dan peluang untuk tiap perubahan komponen iklim, akan dapatditentukan dampak negatif dan dampak positif dari suatu fenomena cuaca dan iklim. Ancaman utama atau dampak negatip perubahan iklim bagi bandara Hasanuddin adalah potensi banjir, kekeringan, kebutuhan energi yang meningkat, rusaknya infrastruktur seperti runway, taxiway dan apron serta terganggunya operasional penerbangan akibat cuaca ekstrim. Strategi adaptasi yang tepat untuk bandara Hasanuddinantara lain dengan peningkatan kinerja sistem drainase, sumur resapan, penerapan efisiensi energi dan penggunaan energi ramah lingkungan, penerapan eco-office serta efisiensi proses dan prosedur kerja dalam pelayanan penumpang di bandara.Kata kunci : bandar udara, adaptasi, perubahan iklim

Abstract

Banjir tanggal 11 Februari 2002 mengejutkan banyak pihak karenadatangnya tiba-tiba dan tidak terduga besarnya, sehingga hampir 30% wilayah Jakarta tergenang air , transportasi lumpuh , dan memakan korban jiwa akibat tanah lingsor, tenggelam, hanyut dan tersengat aliran listrik. Total aliran air permukaan diperkirakan mencapai 70 juta meter kubik, dimana jumlah tersebut tidak dapat tertampung oleh badan-badan sungai yang ada dan meluap menggenangi daerah dataran banjir sungai (floodplain area) yang saat ini banyak ditempati oleh pemukiman penduduk. Berdasarkan hasil studi yang dilakukan oleh Kelompok Pengkajian Sitem Pengelolaan Air (BPPT) dalam Studi Studi Model Optimisasi Pengelolaan Air Tanah Jakarta, maka besarnya imbuhan buatan yang harus dimasukkan kembali kedalam akuifer dangkal untuk daerah seluas 25 km2 berkisar antara 1.082.419- 54.120.960 m3/tahun atau antara 1,08 - 54,12 m3/tahun/m2. Lokasi imbuhan buatan dapat dilihat pada Peta Lokasi Imbuhan Buatan Berdasarkan Hasil Optimisasi Pengelolaan Air Tanah. Jika diasumsikan 1 (satu) sumur resapan dengan diameter 0,8 meter, lebar bidang resapan 1 meter pada tanah dengan permeabilitas rendah (0,00105 m/hari), maka kapasitas sumur resapan adalah 0,592 m3/tahun/unit. Dengan demikian untuk daerah Jakarta dan sekitarnya dibutuhkan kurang lebih 2 juta sumur resapan. Pelestarian lingkungan merupakan tanggung jawab pemerintah dan masyarakat. Walaupun sudah ada Surat Keputusan GubernurDKI yang mengatur tentang sumur resapan, pelaksanaan dilapangan masihsulit pengawasannya. Dalam kondisi krismon ini perlu langkah terobosan untuk membuat sumur resapan dengan program jaring pengaman sosial, dengan demikian pemerintah membuka lapangan pekerjaan bersamaan dengan perbaikan lingkungan.
