Abstract

Distribution pattern of Escherichia coli to indicate the ground water quality in Tebet District South Jakarta. Most citizen in Tebet District use ground water as one alternative to daily pure water need. A report of BPLHD DKI (2008) indicated that 80% of ground water sample from 75 wells in 75 sub districts in Jakarta were Escherichia coli (E. coli) bacteries polluted from water septic tank. One of reasons that ground water was polluted is due to the highly rapid growth citizen and the ever-limited area. Physic parameter is temperature while the chemical parameters are pH and Dissolved Oxygen, and biologic parameter is E. coli bacteries. Checking of E.coli contain in ground water in Tebet sub district used Most Probable Number (MPN) method from SNI 01-2332-1991. Report of this research showed that ground water in Tebet Sub district have range total of bactery E. coli from 3 MPN/100 ml to 160 MPN/100ml. As a result of correlation test we get relation between total amount of E.coli bacteries against well depth and distance of septic tank. The more shallow depth of well and closer distance of septic tank and pure water source, the more E.coli bacteries consists in ground water. Distributing pattern of E. coli bacteries can be explained with mathematic model with helper of program surfer. Distributing pattern of E. coli in Kebon Baru, Bukit Duri and Manggarai and West Tebet and go to left bottom of spread of E.coli become increase.   Abstract in Bahasa Indonesia:  Sebagian besar penduduk di Kecamatan Tebet memanfaatkan air tanah sebagai salah satu alternatif dalam pemenuhan kebutuhan air bersihnya. Berdasarkan laporan dari BPLHD DKI (2008) bahwa 80 persen sampel air tanah dari 75 sumur di 75 kelurahan di Jakarta tercemar bakteri Escherichia coli (E. coli) yang berasal dari rembesan tangki septik. Salah satu faktor penyebab pencemaran air tanah adalah tingginya kepadatan penduduk dan keterbatasan lahan sehingga fasilitas sanitasi tidak terencana dan terbangun dengan baik, seperti : jarak tangki septik dan saluran drainase yang terlalu dekat dengan sumur air bersih. Daerah Padat penduduk dan tingginya penggunaan air tanah di Kecamatan Tebet menjadi sasaran utama dalam penelitian ini. Parameter fisik yang diukur, yaitu suhu, parameter kimia, yaitu pH dan DO dan parameter biologi, yaitu bakteri E. coli. Pemeriksaan kandungan Bakteri E. coli pada air tanah di Kecamatan Tebet menggunakan metode Most Probable Number (MPN) yang mengacu pada SNI 01-2332-1991. Hasil penelitian menunjukkan bahwa jumlah bakteri E. coli pada air tanah di Kecamatan Tebet berkisar antara 3 MPN/100 ml sampai 160 MPN/100 ml. Dari hasil uji korelasi diketahui bahwa jumlah bakteri E. coli pada air tanah dipengaruhi oleh kedalaman sumur dan jarak tangki septik terhadap sumur air tanah. Semakin rendah kedalaman sumur air tanah dan semakin dekat jarak tangki septik terhadap sumur air tanah maka semakin buruk kualitas air tanahnya dan jumlah bakteri E. coli yang terkandung di dalam air tanah pun semakin banyak. Pola persebaran bakteri E. coli dapat dijelaskan dengan menggunakan model matematis dengan bantuan program surfer. Pola persebaran bakteri E. coli di Kelurahan Kebon Baru, Bukit Duri dan Manggarai semakin ke arah kanan atas semakin tinggi, sedangkan untuk di Kelurahan Menteng Dalam dan Tebet Barat semakin ke arah kiri bawah sebaran bakteri E. coli semakin tinggi.

Abstract

Design of Sewerage System for Housing Area of Alam Sutera, Serpong-Tangerang. Alam Sutera is housing area at Serpong-Tangerang which have the total area approximately 818,23 Ha. The system sanitation is still an on-site system. This paper described the sewerage system design which is better than on-site system that will give the worse impact to the groundwater environment than the sewerage system. It is planned to serve 100% of the resident until the area fully loaded. At the end of the the planning time design of the Alam Sutera’s sewerage system will serve the total resident of 34.096 people. The maximum day factor is 1,35 and the wastewater percentage is 77,16% from water demand which was analyzed with statistics methode due to the 45 datum from 26 refferences. The average debit of wastewater in the year end of the planning are 2,28 L/dtk/1000 people. This design gives 3 options of the main pipe line of the sewerage system. The first is the line in the south will be in the main road, and pass main road in cluster, total pipe length is 9440 m. The second is the main pipe at the south part area will pass the main road of Alam Sutera, it causing an easy repair system if any error occurred or during the operational. At north area, pipe line will pass the same line in alternative 1, total pipe length is 9490 m. The selection of the third applies the consideration result of Qpeak calculation in the south part from alternative 1 and 2, and selected to apply the line at alternative 1. In the north, pipe line will pass the main road in cluster, it made pipe become longer (9910 m). Due to the investation cost alternative 1 is chosen which result are 200-700 mm pipe diameter, 9.440m length, 93 units of manhole, housing connections 6984 units, and the total investment of the sewerage system plus wastewater treatment is Rp. 18.719.372.368,-, but if the operational cost is considered, the alternative 3 will be cheaper eventhough the main pipe is longer than alternative 1(9.910 m)   Abstract in Bahasa Indonesia:  Perumahan Alam Sutera merupakan perumahan yang terletak di daerah Serpong-Tangerang, dengan total lahan pengembangan seluas 818,23 Ha. Perumahan ini adalah salah satu contoh kawasan perumahan dan komersial yang masih menggunakan sistem setempat (on site). Makalah ini akan memberikan gambarang tentang sistem penyaluran air buangan (SPAB) yang akan memberikan suatu dampak lingkungan yang lebih baik daripada sistem sanitasi setempat. Perencanaan penyaluran air buangan yang akan dilakukan sampai perumahan tersebut terisi penuh merupakan area. Sampai dengan akhir perencanaan, perencanaan SPAB akan melayani 34.096 orang, dengan kriteria desain berdasarkan hasil analisis data setempat yaitu : Faktor hari maksimum adalah 1,35, persentase air buangan adalah 77,16% dari pemakaian air bersih yang dianalisis dengan methode statistik berdasarkan 45 data dari 26 referensi. Debit rata-rata sampai dengan akhir tahun perencanaan adalah 2,28 l/dt/1000 jiwa. Perencanaan ini memberikan 3 alternatif jalur pipa utama yaitu alternatif 1 dengan panjang pipa = 9.440 m. Alternatif 2 dengan pertimbangan kemudahan perbaikan bila ada kerusakan dalam operasionalnya. Di bagian uatara jalur pipa utama sama dengan rencana jalur alternatif 1, dengan panjang pipa 9.490 m. Pemilihan alternatif 3 ini menggunakan pertimbangan hasil perhitungan Q peak pada bagian selatan dari alternatif 1 dan 2, alternatif yang terbaik digunakan untuk alternatif 3, sehingga diperkirakan dapat mengurangi jumlah biaya karena Q peak yang digunakan lebih kecil, dengan total panjang pipa terbesar yaitu 9.910 m. Berdasarkan pertimbangan biaya investasi, alternatif 1 dengan hasil pipa berdiameter 200-700 mm, panjang 9.440 m, 93 buah manhole, sambungan rumah 6984 unit, dengan total investasi SPAB + IPAL = Rp. 18.719.372.368,-, tetapi bila biaya operasional sebagai bahan pertimbangan, maka alternatif 3 akan lebih murah meskipun panjang pipa utama terpanjang (9.910 m). Hal ini karena kebutuhan penggelontoran lebih sedikit dibandingkan alternatif yang lainnya.

Abstract

The Jakarta groundwater is one of the water resources in which people rely on it in great deal. With the limitation of the Water Supply Company to serve its user, groundwater becomes very valuable and dependable resource. The magnitude of extraction reaches out above it’s save yield. In the year of 2002 about 1230 to 1590 millions cubic meters water were accumulated from precipitation. Approximately of 1027 million cubic meters each year about to be consumed by the people of Jakarta. The groundwater consumption tend to increase while the land capability to absorb groundwater decreasing as the land development expanding. Hidrologically the hydraulic conductivity of the Jakarta groundwater aquifer system is very low, so that the groundwater flowrate from the south region of Jakarta basin is also low. With the magnitude of extraction’s very havily, the cone of depression incident has been occurring in the north Jakarta region. Along with this incident, a land subsidence was also occurring in the neighboring area. To overcome these problems, the assessment of the artificial recharge to the Jakarta aquifer particularly at the critical locations has been done. Schemes of the artificial recharges were simulated. Locations and magnitudes of these schemes were recommended to prevent further depression and saltwater intrusions. Key words : groundwater, aquifer, basin Jakarta, simulation, artificial recharge.

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.
