Abstract

Water pollution because of the domestic wastewater produced by the local community and their home industries in a big city, such as Jakarta, has already been inviting many environmental problems since the last ten years. Based on the research done by Directorat General Cipta Karya, Public Works Department RI, domestic wastewater in Jakarta delivers 75% of all pollutants in surface water pollution. Therefore many things should be done to solve those water pollution problems. A lot of environmentally related rules have established in Indonesia, but they are not able to be optimally implemented because of some weaknesses of the environmental rule contents. One of the solving options is to create a perfect regulation system for wastewater management. The laws for home industry wastewater management, especially in big cities, have to be perfectly completed, mainly in the field of standard, operation and procedure, the wastewater quality standard, the adequate and qualified technology, the landscape and building planning and the institutional coordination. If the all environmental regulations are well synchronized, the law enforcement will be simply implemented. By applying them consistently, the water pollution control will be handled well. Keywrods : Environmental Regulation, Home Industry Waste Water, Institutional Coordination

Abstract

Industry is a potential source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. Inorganic industrial wastes are more difficult to control and potentially more hazardous Industries discharge a variety of toxic compounds and heavy metals. The most pollutans heavy metals are Lead, Cadmium, Copper, Chromium, Selenium,  Mercury, Nickel, Zinc, Arsen and Chromium. Heavy metals are dangerous because they tend to bioaccumulate. Mercury for example, causes damages to the brain and the central nervous system, causes psychological changes and makes development changes in young children. Normally Mercury is a toxic substance which has no known function in human biochemistry. There are several methods to eliminate or remove mercury in water such as chemical oxidation process, ion exchange process, adsorption process, an electrochemical process, reverse osmosis process and other alternative methods likes biosorption. Each method has strengths and weaknesses, therefore to choose the method of removing of mercury in wastewater depending on pollutants conditions such as concentrations of mercury in wastewater, types of mercury, mercury concentrations in treated water, land availability, flow rate of wastewater will be processed and other parameters. This paper discusses several methods of removal of mercury heavy metals in industrial wastewater such as chemical precipitation and oxidation processes, adsorption and ion exchange process. Keywords : water pollution, heavy metals, mercury, industrial wastewater, removal methods.

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

Piles and pile foundations have been in use since prehistoric time. The commonest function of piles is to transfer a load that cannot be adequately supported at shallow depths to a depth where adequate support becomes available. When a pile passes through poor material and its tip penetrates a small distance into a stratum of good bearing capacity it is called a bearing pile. When piles are installed in a deep stratum of limited supporting ability and these piles developed their carrying capacity by friction on the sides of the pile, they are called friction piles. Many times the load carrying of piles results from a combination of point resistance and skin friction.  The load taken by a single pile can be determined by static load test. The allowable load is obtained by applying a factor of safety to the failure load. Although it is expensive, a static load test is the only reliable means of determining allowable load on a friction pile. In this case,“Cerucuk” are widely used in foundation engineering to increase bearing capacity of the foundation andreduce the settlement. Keywords : Pile foundation, bearing capacity, skin friction.

Abstract

Water pollution in the big cities in Indonesia, especially in DKI Jakarta has shown serious problems. One of the potential sources of water pollution is domestic wastewater that is wastewater from kitchens, laundry, bathing and toilets. These problems have become more serious since the spreads of sewerage systems are still low, so that domestic, institutional and commercial wastewater causes severe water pollution in many rivers or shallow ground water. Based on the fact that the progress of development of sewerage system is still low, it is important to develop low cost technology for individual house hold or semi communal wastewater treatment such as using anaerobic and aerobic submerged biofilter. This paper describes the pilot plan study of individual household wastewater treatment using anaerobic and aerobic submerged biofilter using plastic fiber media. The raw wastewater in this experiment was from household wastewater. Results of experiment shows that under operating condition 12-24 hours hydraulic retention time, the treated water was physically very clear, and according on chemical analysis the removal efficiency of BOD is 73.24 – 94.92 %, COD 65.80 – 90.76 %, total suspended solids (TSS) 95.60 – 97.69 %, and detergent (MBAS) 56.80 – 88.51 %, respectively. Compared to attempt by using charcoal media, the quality of treated water did not show  difference significantly.  Kata Kunci  : Limbah domestik non toilet, biofilter anaerob-aerob, media serat palstik.
