Abstract

This paper describes some of the general condition of the oceanographic parameters in the Strait Matak, Anambas Archipelago. The data flow is obtained by direct measurement by using a current meter types RCM-7. Simulation models using Mike 21. Mike flow pattern is divided into two seasons, namely west season (January) and the east season (August) and flow patterns ahead of the tide when the season is generally moving west to wards the south, it demonstrates the role of strong tidal influence the movement of waterin the study area. Flow velocity in the strait just before the tide on the west season reaches 1m/s.  Flow patterns at high tide on the west season looks still moving toward sthe south. The maximum flow velocity in the strait when the tide reaches 0.32 m/s, while the average speed in the area of the model is 0.12 m/s. Low tide towards the current pattern is still moving towards the south, it reinforces the notion that in addition to tidal windsare also very significant role in moving the flow, in this case that the current is moving toward the south. Flow velocity just before low tide reaches 0.85 m/s. Flow patterns at low tide shows the differences in the three previous conditions, the current in the strait to move out to the north toward the South China Sea. In condition slow tide, the tida lmore dominantly than the wind, this proved to even though the wind toward the south, the currents inthestraitis moving toward snorth along the tidal flow leading to the South China Sea. Flow velocity is quite varied location of modeling; flow velocity at low tide reaches 0.5m/s, with the average 0.15 m/s. Keywords: current and direction, wind, tide, model.

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 heavy metals 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 heavy metals in wastewater depending on pollutants conditions such as concentrations of heavy metals in wastewater, types of heavy metal, heavy metal concentrations in treated water, land availability, flow rate of wastewater will be processed and other parameters. In this paper discusses several methods of removal of heavy metals in industrial wastewater such as chemical precipitation and oxidation processes, adsorption and ion exchange process. Keywords : water pollution, heavy metal, industrial wastewater, removal methods

Abstract

More than 90 % of Jakarta livestock supply, especially poultry, originated from outside the area. Meanwhile temporary places and slaughterhouse are spread out in some locations in Jakarta area, even most of them located in residences area. Almost all wastewater are not processed but straightly discharged to the sewer or river around the house. These spread chickens slaughterhouse activities caused environmental pollution which is difficult to control.This paper discussed about the design of wastewater process installation of chickens slaughter by biofilter anaerob-aerob process and test of its process result. Based on the test the removal efficiency of COD, Permanganate, BOD and Total Suspended Solid (TSS) were 86.52 %, 82.85 %, 88.79 % and 94.1 % respectively.. Keyword : Design, process, wastewater, chicken slaughterhouse, biofilter.

Abstract

Water is a very basic need for humans, especially for cooking and drinking. With the rapid growth of population in particular need of clean water for the community also increased in numbers. The problem is with the poor quality of raw water for drinking water, then in addition to expanding its production costs, the result is often less good. One of the problems or issues that are often found in drinking water in the world these days that is the emergence of compounds called Trihalomethanes or THMs abbreviated, as a side effect of the disinfection process with a chlorine gas or hypochlorite compounds.Currently, to removal organic pollutants, ammonia, detergents, odor and other micro pollutants in drinking water, PAM is usually used by the process of manufacturing processes using adsorbsi Powder Active Carbon Adsorption, continued with physicals processing is the process of coagulation, flocculation, sedimentation and disinfection with chlorine. With increasingly high prices of powdered activated carbon, coagulant and flocculant chemicals, then the cost of treating drinking water to be increasing. To solve the problem above, one alternative is to develop clean water treatment technologies using a combination of biofiltration and ultrafiltration process, and to produce drinking water to proceed with processing using the process of reverse osmosis. Within the combination of biofiltration, ultrafiltration and reverse osmosis processes to treat the river water can be produced the drinking water with a very good quality without the use of chemicals for coagulation-flocculation process, and operational costs are relatively low. Key words : Air siap minum, biofiltrasi, ultrafiltrasi, reverse osmosis

Abstract

The existence of regulations to control environmental pollution has grown over time in line with changes in environmental legislation. In Indonesia since the '80s has been three times experience changes in environmental legislation. Any change in the law is always followed by changes in regulations that are below it. From time to time, the environmental pollution is getting worse and require stricter regulations and implementation. Regulations are too strict sometimes not implementable and eventually are violated because there is no way out solution that does not burden the parties. Domestic waste is the largest portion of urban waste. Its existence has made the environment of rivers, lakes and ground water polluted, due to not properly managed. Regulation of waste quality standards have been tightened over time. Waste water quality standard is the limit or polluted substance or the amount of pollutant elements are tolerable in the waste water to be discharged or released into the water source from a business or activity. The existence of environmental quality standards in Indonesia are set by regulations of environment ministers. Discharge of domestic waste quality standards number P.68 / Menlhk / Secretariat / Kum.1 / 8/2016 has brought on changes in the use of domestic wastewater treatment technologies, as happened tightening in several key parameters, which is still within the limits loose. Keywords : Environmental regulation, waste treatment technology

Abstract

Most of the leachate treatment in Indonesia using pond system, that is maturation ponds, anaerobic ponds, stabilization ponds, and continued using wetland. The weakness of this technology is long retention time (between 30-50 days), thus the building a pond requires a wide area. In addition, the processed leachate is over quality standards to be discharged into the environment agency. To overcome these problems, one alternative is to use a combination of processing leachate within anaerobic-aerobic biofilter and denitrification. The technology is expected to shorten the residence time, so that the land required for the processing of leachate is not too extensive . The processed leachate is also expected to meet the quality standards are allowed to be discharged into the environment. Leachate treatment using anaerobic - aerobic biofilter and the denitrification process with a total hidraulic retention time of 12 day, the retention time in the anaerobic reactor 8 ( eight ) days , the retention time in the aerobic reactor 3 (three) days and retention time in the denitrification reactor 1 (one) day can be generated COD removal efficiency of 97 %, ammonia removal efficiency of 97.56 %, TSS removal  efficiency 87.5 % , and nitrate removal efficiency of 86.4 % Keywords : Anaerob-aerob biofilter, denitrification, leachate.

Abstract

The level of water services by PDAM (Local Water Service Company) is still 19,4% of Indonesian population. Most of them still rely on groundwater, spring, river and rain. In the big and medium cities the level of water services higher between 40 – 50 and 20 - 30% respectively, but in rural still very low. Recently many source of water is contaminated by domestic, industry, and agricultur waste due to lack of attention of water users to environment.  Beside, some dense populated areas with low sanitation fasility make many shalow well contaminated by E.coli. For improving rural water services, It needs  government policy that encourage bigger role of rural comunity to develop their ability and organization that maintain and protect source, process, production and distribution of water. Information of  Simple Water Treatment Technology is an important that must be distributed to people who live in village or remote areas,  in order to improve their knowledge. BPPT has been along time to develop many kind of water treatment technologies for treating river water, groundwater, peatwater, calcareous water,poluted water,  brachist water or even sea water to make clean water or potable water. Many of those technologies have already applied in many areas in Indonesia, and up to now BPPT still develop many kind of water treatment technologies for the future. Kata Kunci : air bersih, pengolahan air, masyarakat pedesaan.

Abstract

Masalah air baku air minum di kota-kota besar misalnya Jakarta, Surabaya, dan kota besar lainnya semakin hari kualitasnya semakin menurun. Hal inimengakibatkan semakin mahalnya biaya produksi air baku dan pada kondisitertentu dapat menyebabkan PAM tidak dapat menghasilkan air yang baik.Dari hasil pemantauan yang dilakukan oleh PAM pada bulan September 2000 terhadap air baku (intake water) di instalasi PAM Cilandak menunjukkan bahwa konsentrasi amoniak bervariasi hingga mencapai sekitar 2,0 mg/l, dimana nilai konsentrasi tersebut telah melampaui ambang batas peruntukkan air baku air minum yakni sebesar 1 mg/l menurut Kep. Gub. KDKI Jakarta No. 582 th 1995.PAM di Indonsia khususnya PAM di DKI Jakarta menggunakan senyawa khlor (gas khlor atau kalsium hipoklorit) yang selain untuk proses desinfeksi juga digunakan untuk menghilangkan senyawa logam Fe, Mn, serta amoniak. Dengan semakin besarnya konsentrasi senyawa amoniak dalam air baku, maka amoniak akan dapat bereaksi dengan khlor menjadi khloramine yang daya desinfeksinya lebih lemah. Hal ini akan mengakibatkan konsumsi khlor akan menjadi lebih besar sehingga biaya operasi menjadi lebih tinggi.Selain itu dengan semakin besarnya konsentrasi senyawa khlor yang digunakan, maka hasil samping yang dihasilkan seperti terbentuknya senyawa trihalometan dan khlorophenol juga semakin besar. Senyawa-senyawa tersebut dapat mengakibatkan penyakit kanker (carcinogen). Oleh karena itu zat pencemar amoniak harus dihilangkan.Untuk mengurangi kadar amoniak di dalam air baku air minum maka air sungai harus diolah terlebih dahulu melalui suatu pengolahan pendahuluan sebelum masuk ke unit pengolahan. Salah satu alternatif yakni menggunakan proses biologis dengan sistem biofilter tercelup yang diisi dengan media penyangga dari bahan plastik tipe sarang tawon.Penelitian dilakukan dengan mengoperasikan secara kontinyu satu reaktor biofilter tercelup menggunakan media palstik tipe sarang tawon dengan, ukuran 210 cm x 30 cm x 59 cm, volume total 371,7 liter.Efisiensi penurunan amoniak berdasarkan variasi waktu tinggal hidrolis 1-3 jam berkisar antara 48,74 % - 73.59 %. Pada pengolahan dengan pengkondisian waktu tinggal hidrolis 1 jam efisiensi penurunan sebesar 48.74%, untuk waktu tinggal 2 jam menunjukkan efisiensi sebesar 67.98 %, untuk waktu tinggal 3 jam efisiensi sebesar 73,59 %.Dari hasil percobaan di dapatkan persaman hubungan antara beban amoniak dengan efisiensi penghilangan amoniak yang ditunjukkan dengan persamaan :Y= -57,896 X + 79,859 di mana Y adalah efisiensi penghilangan amoniak (%), dan X adalah beban amoniak yang dinyatakan dalam gram amoniak/m2 media per hari, dengan nilai R (regresi) dengan harga R2 = 0,7486. Dari hasil tersebut terlihat bahwa dengan beban amoniak sebesar 0,1–0,7 gr/m2.hari di dapatkan efisiensi penghilangan amoniak antara 40 – 75 %.
