Abstract

Jambakan is a hamlet in Bayat District, Central Java Province, Indonesia, which commonly has brackish groundwater. Its unique geological profile leads to variation in groundwater quality that is even found between adjacent wells. This study was designed to identify the quality and hydrochemical type of groundwater and the distribution of brackish groundwater in Jambakan. It employed a quantitative method to analyzethe data collected in the field survey and groundwater quality data (major ions). Meanwhile, the hydrochemical facies of groundwater was interpreted from the plots of major ions on trilinear and quadrilateral Piper diagrams. The results showed that some of the groundwater quality parameters in six wells, namely A6, A34, A38, A65, A67, and A73, had exceeded the standard thresholds. The parameters in question were TDS, EC, salinity, sodium, calcium, chloride, sulfate, magnesium, and hardness. Compared with the six wells, A40 and A45 had better quality. The distribution of brackish groundwater could not be modeled horizontally because salinity highly depends on rock layers where the observed wells are located. Based on the trilinear Piper plots, the groundwater consisted of four hydrochemical facies, namely magnesium bicarbonate, a mixed type, calcium chloride, and sodium chloride. Meanwhile, the quadrilateral Piper diagrams showed the presence of Type I (bicarbonate water), Type II (semi-bicarbonate water), Type III (evaporite water), and Type IVb-IVc (sulfate water) in the groundwater of Jambakan Hamlet.

Abstract

ABSTRAK: Masalah pengolahan air terproduksi di wilayah penambangan Wonocolo mulai menjadi perhatian sejak ditetapkannya Wonocolo sebagai Petroleum Geoheritage. Air terproduksi yang ikut terangkut ke permukaan pada saat pengambilan minyak bumi di sumur minyak Wonocolo memiliki tingkat kekeruhan 105 NTU, Total Dissolved Solids (TDS) 1714 mg/L, Total Suspended Solids (TSS) 90 mg/L, dan nilai COD 77,9 mg/L. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh media filtrasi pasir aktif dan karbon aktif sebelum air dimasukkan ke membran bioreaktor. Hasil pengolahan air terproduksi tanpa menggunakan media filtrasi menghasilkan air dengan tingkat kekeruhan 0,33 NTU, COD 35, TSS 8 mg/L dan efisiensi penurunan TDS 90,45 %, sedangkan dengan pasir aktif menghasilkan tingkat kekeruhan 0 NTU, COD 7,1 mg/L; TSS 6 mg/L, dengan efektivitas penurunan TDS 91,85%. Sementara pada media karbon aktif, tingkat kekeruhan 0,27 NTU; COD 10,5 mg/L; TSS 4 mg/L dengan efektivitas penurunan TDS 90,97%. Pengolahan menggunakan media filtrasi menghasilkan air yang memiliki kualitas lebih baik dari pada tanpa filtrasi. Media filtrasi pasir aktif lebih baik daripada karbon aktif. Media filtrasi juga dapat menurunkan beban membran dalam mengolah air.Kata Kunci: Air terproduksi; Membran bioreaktor; pasir aktif; karbon aktif ABSTRACT: The issues of produced water has become very much considered  since the stipulation of “Wonocolo” as Petroleum Geoheritage. Produced water transported to the surface during oil extraction at the Wonocolo oil well has a turbidity level of 105 NTU, Total Dissolved Solids (TDS) of 1714 mg / L, Total Suspended Solids (TSS) of 90 mg / L, and COD value of 77.9 mg / L. The purpose of this study was to determine the effect of filtration media (active sand and activated carbon) before water was put into the bioreactor membrane. The results of water treatment without using filtration media produced water with turbidity levels of 0.33 NTU, COD 35 mg/L, TSS 8 mg L and efficiency of TDS reduction of 90.45% while using active sand produced water with turbidity levels of 0 NTU, COD 7.1 mg/L, TSS 6 mg L and efficiency of TDS reduction of 91.85%. For activated carbon, turbidity level was 0.27 NTU, COD 10.5 mg/L, TSS 4 mg L and efficiency of TDS reduction of 90.97%. From the results of the analysis, processing using filtration media produces water that has better quality and active sand filtration media better than activated carbon.Keywords: Produced water; Membrane bioreactor; active sand; activated carbon

Abstract

Penelitian ini bertujuan untuk mengetahui kualitas air Sungai Winongo dan pengaruh aktifitas masyarakat terhadap kualitas air sungainya. Metodologi yang digunakan dalam penelitian ini adalah survey lapangan, wawancara, dan analisis laboratorium. Kualitas air dianalisis berdasarkan beberapa parameter seperti fisika, kimia, dan microbiologi. Pengamatan kualitas air sungai dilakukan di dua lokasi pada kawasan perkotaan. Pencemaran sungai ditandai dengan adanya nilai kualitas air yang melebihi baku mutu airseperti BOD, COD, nitrat, detergen, fenol, dan coliform total. Dari hasil analisis kualitas air sungai tersebut, ditemukan bahwa tingkat pencemaran pada lokasi 2 (Kel. Tegalrejo, Kec. Tegalrejo) secara umum lebih tinggi dibandingkan pada lokasi 1 (Kel. Pringgokusuman, Kec. Gedong Tengen). Hal tersebut disebabkan oleh adanya aktifitas masyarakat sekitar yang tidak memperhatikan kebersihan lingkungan sungai seperti menumpuk sampah di tepi sungai dan membuang air limbah (industri tahu, rumah tangga, dan peternakan) langsungke sungai.

Abstract

Menjadi daerah sub urban, Desa Sidoarum, Kecamatan Godean, Kabupaten Sleman, D.I Yogyakarta mengalami peningkatan kebutuhan air karena pertambahan penduduk dari beberapa tahun belakangan. Jumlah penduduk yang terus meningkat mendukung terjadinya perluasan wilayah permukiman dan perkembangan sarana infrastruktur yang mendukung kegiatan masyarakat sehari-hari. Alih fungsi penggunaan lahan di suatu wilayah perlu disesuaikan dengan berbagai kegiatan masyarakat dan pemanfaatan ruang dalam upaya menjaga kondisi airtanah. Untuk mengetahui kondisi airtanah di sebagian Desa Sidoarum, maka bisa dianalisis berdasarkan tingkat kerentanan airtanah yang berkaitan dengan kondisi daerah penelitian. Tujuan dari penelitian ini adalah mengetahui zonasi tingkat kerentanan airtanah terhadap pencemaran dengan metode DRASTIC dan penentuan manajemen bencana melalui metode analisis deskriptif kualitatif. Hasilnya terdapat 2 zonasi kerentanan airtanah, yaitu zonasi tingkat kerentanan tinggi dan zonasi tingkat kerentanan sangat tinggi. Model manajemen bencana yang digunakan adalah disaster risk reduction framework berupa identifikasi risiko bencana. Pelaksanaan manajemen bencana tersebut dibutuhkan arahan pemanfaatan ruang secara konsisten dan terpadu, serta Pemerintah baik daerah maupun pusat dapat membuat regulasi sistematis terkait pembangunan berkelanjutan berwawasan lingkungan berdasarkan tingkat kerentanan airtanah.

Abstract

The upstream of Bompon sub-watershed is located in Magelang Regency, Central Java. The movement of soil mass and erosion often happens at Bompon sub-watershed. The occurrence of erosion is caused by high runoff so the soil and rocks become eroded and the loose material will enter the river body. The purpose of this study is to determine the characteristics and application of eco-hydraulics in the Upper Bompon watershed. The methods used include survey, mapping methods and mathematical methods. Preparation stage were done by collecting secondary data which were used as the basis for field data collection. The field work phase include collecting primary data by crosschecking and mapping. Furthermore, measuring river flow and observing the name of the flora. The results of the study showed that the width of the river was 1.1 m, the same as rice field irrigation channel with the pattern of dendritic drainage. The highest river flow discharge was 0.043 m3/s that occur in January, while the lowest was in June with river discharge of 0.010 m3/s. Eco-hydraulic application uses cliff restraint methods, namely cliff planting, cliff cover, cliff plants, flat fences and the use of gulud terraces. Keywords: River Flow Discharge, Ecohydraulic, Erosion, Upstream.
