Abstrak: Usaha laundry merupakan usaha yang sedang menjamur di kota Bandung. Usaha ini membawa manfaat untuk kondisi ekonomi masyarakat, tetapi disamping itu juga mempunyai dampak negatif bagi lingkungan karena adanya timbulan limbah. Limbah deterjen termasuk polutan lingkungan karena didalamnya terdapat Linear Alkylbenzene Sulphonate (LAS) yang bersifat toksik dan dapat mencemari badan air. Metode alternatif yang dapat digunakan adalah fotokatalis dengan menggunakan katalis semikonduktor ZnO dan impregnasi ZnO/zeolite dengan proses oksidatif menggunakan spesi radikal OH yang menghasilkan CO2 dan H2O. Penelitian ini bertujuan untuk mengetahui prinsip kerja fotokatalis dan efektivitasnya menggunakan ZnO dan impregnasi ZnO/zeolite serta menentukan pH optimum, dosis optimum, dan kinetika laju reaksi yang terjadi. Limbah yang digunakan adalah artifisial surfaktan jenis LAS dalam reaktor fotokatalis yang dilengkapi dengan UV A (Î» = 365 nm). Parameter yang diuji adalah degradasi surfaktan dengan metoda MBAS. Pada perolehan data awal didapat karakteristik awal limbah sebesar 32.06 mg/L. Proses fotokatalis dengan ZnO dan ZnO/zeolit pada variasi pH menghasilkan efisiensi penyisihan yang baik pada kondisi asam sebesar 93.66% dan 47.03%. Sementara dosis optimum yang didapat untuk ZnO sebesar 0.5 g/L dan 0.25 g/L untuk impregnasi ZnO/zeolit. Penyisihan menggunakan ZnO lebih baik dari pada penggunaan hasil impregnasi ZnO dengan zeolit dengan penyisihan hingga 90% dengan mengikuti laju reaksi orde 1 atau sama dengan kinetika reaksi Langmuir-Hinshelwood. Jadi dapat disimpulkan bahwa metode impregnasi ZnO/zeolit tidak efisien digunakan sebagai untuk mendegradasi senyawa LAS dan mungkin perlu dilakukan penelitian lanjutan untuk mendegradasi senyawa LAS dengan menggunakan metoda impregnasi. Kata kunci: limbah laundry, LAS, fotokatalis, ZnO, impregnasi ZnO/zeolite. Abstract : Laundry is a booming business in Bandung. This venture brings substantial benefits to economic conditions, but in addition it also has a negative impact on the environment due to the waste product. Detergent's wastewater including environmental pollutant that has Linear Alkylbenzene Sulphonate (LAS) which is toxic and can contaminate the water body. Some treatment can be used is photocatalyst using a Zinc Oxide (ZnO) and impregnation of ZnO/zeolite with oxidative processes using OH radical spesies that produce CO2 and H2O. This study aim to determine the working principle of photocatalyst and effectiveness using ZnO and impregnation of ZnO/zeolite, determine the optimum pH, optimum dose, and the kinetics model of reaction. The waste used is an artificial surfactant (LAS type)on the reactor photocatalyst with UV A lights (Î» = 365 nm). The parameters were measured the surfactant degradation with MBAS method. On the acquisition of preliminary data obtained initial characteristics of waste by 32.06 mg/L. Photocatalyst process with ZnO at pH variation has good removal efficiency under acidic conditions with initial concentration of 31.45 mg/L with an efficiency of 93.66% and 47.03% for impregnating ZnO/zeolite. The optimum doses for ZnO catalyst about 0.5 g/L and 0.25 g/L for ZnO/zeolite impregnating. LAS degradation using ZnO can degrade the organic compound of LAS is better than ZnO/zeolite with degradation result reach 90% following the first order reaction or Langmuir-Hinshelwood kinetics. So from this experiment, we can conclude that the impregnation of ZnO/zeolite not efficient for degrade LAS compound within surfactant and need to do the next experiment of LAS degradation with impregnation method. Keywords: Laundry wastewater, LAS, photocatalyst, ZnO, impregnation ZnO/ zeolite

Abstrak: Arsen adalah elemen jejak bersifat toksik dan dapat menyebabkan berbagai dampak negatif terhadap kesehatan manusia. Salah satu sumber paparan arsen untuk manusia adalah melalui air tanah. Air tanah yang terindikasi memiliki kandungan arsen tinggi salah satunya adalah air tanah yang berada pada lokasi yang terpengaruh oleh sistem panas bumi. Kontaminasi arsen pada air tanah merupakan suatu permasalahan global yang cukup serius dan telah didapati kontaminasi arsen pada air tanah terjadi di Taiwan, Chile, Bangladesh, Argentina, Meksiko, China, dan India. Sub-DAS Ciwidey merupakan area di salah satu lereng Gunung Patuha yang terletak di selatan Cekungan Bandung memiliki banyak manifestasi panas bumi yang merupakan salah satu sumber polutan alami yang merupakan polutan vulkanogenik. Penelitian yang dilakukan pada sampel air tanah dangkal di Sub-DAS Ciwidey menunjukkan bahwa konsentrasi arsen berkisar 0.001 mg/l sampai dengan 3.25 mg/l, melebihi batas aman yang telah ditetapkan oleh WHO dan Indonesia yaitu 0.01 mg/l. Metode geostatistik dengan Simple Kriging tanpa transformasi memberikan hasil prediksi yang paling akurat. Interpretasi kehadiran arsen berdasarkan analisa geokimia air tanah menggunakan Diagram Schoeller menunjukkan hasil bahwa air tanah di lokasi studi berasal dari sumber yang sama, dan terpengaruh oleh sistem panas bumi. Dengan demikian, maka diperkirakan sebanyak 430,600 jiwa berisiko terpapar oleh kontaminasi arsen di air tanah dangkal yang melebihi batas aman yang telah ditetapkan WHO. Kata kunci: arsen, panas bumi, air tanah dangkal, Sub-DAS Ciwidey, metode kriging Abstract: Arsenic is a toxic trace element that can cause various negative impacts on human health. One of arsenic exposure source for humans is through groundwater. One of groundwater indicated with high arsenic content, is groundwater in a location affected by geothermal systems. Arsenic contamination in groundwater is a serious global problem and arsenic contamination in groundwater has occurred in Taiwan, Chile, Bangladesh, Argentina, Mexico, China and India. Ciwidey Sub-watershed is an area on Mount Patuha slope located in the south of Bandung Basin has many geothermal manifestations which is one source of volcanogenic pollutant, including arsenic. A study conducted on shallow groundwater samples in Ciwidey Sub-watershed showed that arsenic concentrations ranged from 0.001 mg/L to 3.25 mg/L, exceeded the safe limits established by WHO and Indonesia. Geostatistical methods with Simple Kriging without transformation provide the most accurate prediction results. Interpretation of arsenic presence based on groundwater geochemical analysis using Schoeller Diagram shows the result that groundwater at the study site comes from the same source, which is influenced by geothermal system. Thus, an estimated 430,600 people are at risk of exposure to arsenic contamination in shallow groundwater beyond the safe limits established by WHO. Keywords: arsenic, geothermal, shallow groundwater, Ciwidey Sub-watershed, kriging method

Abstrak : Perlindungan terhadap sumber daya airtanah dapat dilakukan dengan membuat peta kerentanan pencemaran airtanah. Informasi yang didapat mengenai sebaran potensi kerentanan pencemaran airtanah di suatu wilayah dapat dijadikan sebagai acuan dalam pembangunan berkelanjutan. Metode DRASTIC merupakan salah satu instrumen untuk mengevaluasi kerentanan pencemaran airtanah. Metode ini cukup popular dan banyak digunakan oleh para peneliti karena baik digunakan dalam skala regional. Akan tetapi tujuh parameter (kedalaman muka airtanah, curah hujan, media akuifer, media tanah, topografi, zone vadose, konduktivitas hidrolis) yang dijadikan dasar analisa tidak mempertimbangkan parameter penutup lahan. Berdasarkan dari hal tersebut pengembangan kriteria penilaian metode yang dimaksud yaitu dengan memasukan parameter penutup lahan. Selain itu penyesuaian mengenai parameter dan bobot yang dikaitkan dengan kondisi wilayah studi di kota Bandung. Pengembangan kriteria penilaian yang dilakukan mengunakan metode Analisis Hirarki Proses (AHP) dengan penyebaran kuesioner dilberikan kepada stakeholder (akademisi, pemerintahan dan masyarakat) berjumlah 30 sampel. Hasil analisa mengenai pengaruh penutup lahan terhadap kerentanan pencemaran mendapatkan bobot paling rendah yaitu sebesar 0,065 sementara yang tertinggi yaitu parameter media penyusun akuifer dengan bobot 0,208.

Abstract:Protection of groundwater resources can be made by creating a vulnerability map of groundwater pollution. The information obtained regarding the potential distribution of groundwater pollution vulnerability in a region can be used as a reference in sustainable development. DRASTIC method is one of the instruments to evaluate the susceptibility of groundwater pollution. This method is quite popular and widely used by researchers because it is well used on a regional scale. However, seven parameters (groundwater depth, precipitation, aquifer media, soil media, topography, vadose zone, hydraulic conductivity) were used as the basis for the analysis did not add land cover parameters as aspects of human activities that could potentially increase vulnerability. Based on the above, the development of assessment criteria method is to include the land cover parameters. Also, adjustments on the parameters and weights associated with the condition of the study area in the city of Bandung. Development of assessment criteria conducted using Analytic hierarchy process(AHP) method with questionnaires distributed to stakeholders (academics, government and society) amounted to 30 samples. The result of analysis of the effect of land cover on the pollution susceptibility obtained the lowest weight that is equal to 0,065 while the highest is the parameter of media of aquifer constituent with weight 0,208. In addition weight changes also occur on some parameters and sub parameters that are analyzed. Keywords: Vulnerability Map, DRASTIC, Land Cover, AHP.

River debris is the main problem from the negative impact of poor waste management. The composition of river debris in Jakarta consists mostly of plastic waste. Plastic waste from river debris has an opportunity for energy recovery. This study aimed to see the potential for utilizing river debris in energy recovery in power plants. This research was conducted at three sampling shelter points in Pesing, Pluit, and Perintis. Waste generation and composition were quantified using the load count method on Indonesian state standards for seven consecutive days. River debris generation in Pesing, Pluitm, and Pernting averaged 7.2; 3; and 1.8 tons/day. More than 60% (w/w) of plastic bag waste was found in the Pesing and Pluit shelters, while 67.3% was found in the Perintis shelter. Based on the calorific value of each plastic waste, the energy potential from plastic waste recovery can reach 16,197,109 kWh/year. This is equivalent to an electricity supply of 0.05% of the total electricity demand in Jakarta.

The Effects of Influent Debit on Hydrodynamic Characteristic of Bojongsoang Facultative Pond: Without Wind Effects. The performance of facultative pond in Bojongsoang WWTP have reported to be unstable. One of the cause of the unstable performance is the hydrodynamic characteristics that not met the criterion. The improper hydrodynamic characteristics are included the existence of dead-zone, the short-circuiting, and the turbulence due to eddy current. The study was to analyze the effect of the influent debit variation on the hydrodynamic characteristics of the pond using mathematical model. The two-dimensional hydrodynamic model was built from two hydrodynamic equations which are continuity and momentum equations. The equations were solved by finite-difference numerical method of semi-implicit (Crank-Nicolson). From the simulation results, the Froude number of the water flow was analyzed. Beside that, the effective residence time and the effective area were calculated. All of them were done to analyzed the existence of the dead-zone in the pond. The simulation results show that the dead-zone was exist in the center of the pond. when the influent debit was larger, the effective residence time and the effective area become larger. The distribution of the Froude number value shows that the area with the value of 10-10 become reduced in the larger influent debit. The existence of the dead-zone was reduced since the influent debit become larger. It can be said that the larger influent debit can improve the hydrodynamic characteristics of the pond.

Microbial fuel cells (MFCs) use bacteria as a catalyst to oxidize organic and/or inorganic substrates and produce electric currents. Wastewater could function as an electron donor in the anode chamber and, thus, represents a very promising energy source. Catholytes, as electron acceptors, influence power production in MFCs by increasing the availability of electrons. The present research aims to determine the influence of catholyte concentration on current production in an aerobic two-chamber MFC. Aerobic treatment was carried out in the two-chamber MFC operated in an incubator at 37  1 °C with and without aeration in the cathode chamber. Wastewater from the chocolate industry was used as a substrate and oxidized by using a bacterial consortium isolated from the sludge wastewater itself. The catholytes used were 0.01, 0.05, 0.1, and 0.3 N NaCl. In the presence of NaCl, the chemical oxygen demand (COD) removal efficiency in the cathode chamber of the MFC was approximately 65%–83% without aeration and 76%–89% with aeration after 72 hours. The current density increased as the catholyte concentration increased to 0.05 N, after which the oxidation process shifted from the anode chamber to the cathode chamber. Addition of O2 to the cathode chamber influenced current production.

The textile industry is one of the industries that discharge an enormous quantity of highly colored wastewater because of the large amount of water used in the process. Textile wastewater is the potential to polluting the environment due to the high color contained in it. One of the problems in processing textile wastewater with conventional treatment methods is the ineffectiveness of color removal. A post-treatment is needed for treated wastewater to remove the color. One of the methods is by using the ozonation method. In this preliminary study, the decolorization of artificial textile wastewater containing azo dye reactive-black 5 (RB5) from secondary treatment was investigated in a batch system. Artificial treated textile wastewater from secondary biological treatment was made using 5,26 mg/L azo dye RB5 in 16 L volume of the reactor. The preliminary batch study showed that the optimum color removal achieved in 24.66 mg/minute ozone dose in a batch system with 20,89 mg/minute ozone consumption. Within 5 minutes of ozonation, color removal achieved was 100%, and COD removal achieved was 75%.
