Analisis Indeks Kualitas Air Lingkungan Pertambangan Batubara PT Kpc Subdas Sangatta Kalimantan Timur

Water quality index (IKA) is one tool to quickly predict the environmental quality status of an ecosystem or region to obtaining an alternative of the future management. Toanalyze the status of these indices utilize only data of environmental parameters that have been established as a key parameter determining the IKA. From the analysis of the mining area of PT KPC IKA with key parameters TDS, DO, COD, nitrogen (N) and phosphorus. (P) derived from the water quality of agricultural ecosystems, industry / mines and residential showed an index value of less well with thecategory (54.6163) on the interval 40 ≤ IKA <60. The low index value is proportional to the low value of ecosystem quality index industry / mining IKA (I) with a value of 45.82with categories of less well on the interval 40 ≤ IKA <60. Consider, that the index value of ecosystem quality residential IKA (H) and agricultural ecosystem quality index IKA (P) with good and excellent categories, then the ecosystem of industry / mining is the focus that needs to be considered for improved management efforts

Peluang Pemanfaatan Rumput Laut Sebagai Agen Biofiltrasi Pada Ekosistem Perairan Payau Yang Tercemar

Some observation result said that the worst of enviromental uality happened is primarily caused by mislead in the aim of develoment nature resources that only concern to economic growth. Therefore, the develoment of brakisth water ecosystem as an economic growth region should be relatedto the goal of enviromental waters uality management. To enhance this goal, the people utilizing brakish water ecosystem as aquaculture site may reduce organic pollution that is producedby their activities. Integrationof Gracilaria sp as a biofilter agent in aquaculture pond or in the wastewater treatment system is an alterantivetechnology for waters quality recovery enhancement.The initial success of this method in some countries has been reported. Therefore, if the biofiltration process in reducing organic pollution run properly, waters pollution in certain brakish ecosystemmaybe reduced

Sebaran Limbah Cair Industri Tekstil Dan Dampaknya Di Beberapa Desa Kecamatan Rancaekek Kabupaten Bandung

Di Kecamatan Rancaekek terdapat industri tekstil yang limbah cairnya diduga mempengaruhi kondisi lingkungan desa-desa seperti Jelegong dan Linggar. Oleh karena itu, penelitian ini bertujuan mengkaji dampak pencemaran industri terhadap kondisi lingkungan hidup di sekitarnya. Hasil analisa air dan tanah menunjukkan air sungai dan lahan pertanian sawah di sekitar industri tekstil mengandung bahan organik dan logam berat dengan konsentrasi yang cukup tinggi. Kandungan bahan organik air Sungai Cikijing yang tinggi ditunjukkan oleh konsentrasi KMnO4 yang tinggi 859,1 mg/l, sedangkan pencemaran tanah oleh logam berat yang tinggi terjadi akibat proses akumulasi dimana konsentrasi Cr (8,56 mg/l), Pb (9,06 – 16,64 mg/l), As (8,4-13,2 mg/l) dan Zn (2,87-92,69 mg/l), sementara konsentrasi logam berat dalam air Sungai Cikijing hanya berkisar antara <0,005 – 0,07 mg/l. Berdasarkan Penelitian tersebut, direkomendasikan upaya meminimalisir dampak pencemaran dengan upaya pentaatan terhadap regulasi pengelolaan limbah cair dan menerapkan teknik fitoremediasi lahan

Karakteristik Dan Keragaman Mikroba Unit Pengolah Limbah Cair Tekstil

One of major pollutants in textile wastewaters is organic substance that could be degraded and utilized by microbe as nutrient and energy source in activated sludge compartment at textile waste water treatment unit. Therefore, microbe is the concern in this observation. Based on the characterization result, such as colony type, Gram stain and microbial shape, there are 13 type of microbegrow in activated sludge. From 13 microbial type, 5 isolates is possibly as Bacillus spp., 4 isolates is to be Flavobacterium spp. and the rest as Pseudomonadaceae

Peran Mikroba Aerob Dalam Pengolahan Limbah Cair Tekstil

The objective of this study is to understand the performance of microbial degradation activities in textile wastewater treatment unit. Result of BOD, COD, DO and microbial measurement indicated that DO concentration in activated sludge wastewater treatment unit was 1.99 and microbial density was around 1 x 107 ind/mL. Based on parameter measured, firstly, the DO concentration is not enough for biodegradation process but this condition still work for biofloculation process; secondly, the BOD and COD ratio is indicating that wastewater compound could not fully degrade, eventhough the microbial density in the wastewater unit is in normal number

Tingkat Filtrasi Rumput Laut (Gracilaria SP) Terhadap Kandungan Ortofosfat (P2o5)

The Concern of this study is to understand Gracilaria sp. function in biofiltration process as a way in removing exceeding nutrient.Laboratory analysis indicated that Gracilaria sp has the ability to reduce organic substance as orthophosphate in see water up to range 0.0082 -00.0149 ppm/days. Application of Gracilaria in waste water filtrattion is expected to be an alternative approach in shrimp pond waste water treatment
