Abstract

Basically, nature has the ability to perform the restoration of environmental damage caused by increased human activity, but because of the limited carrying capacity, then the environment has decreased the quality from year to year. In saving the environment, technology plays a role in reducing the risk of pollution, increased efi siensi process, and creating processes and environmentall friendly products, monitoring and prediction of environment quality, environmental pollution control, restoration and environmental improvement. Waste Technology (end of pipe technology) are widely used to cope with environmental pollution, both for liquid waste, solid and air. Waste processing technology developed for the waste can be in accordance with quality standards thathave been established, while monitoring technology has been developed either manually or automatically. For recovery and improvement of technology has been developed remedies and restoration that rely on bacteria in nature.Keywords: end of pipe technology, reuse, recycle, reduce (3R), carrying capacity, and environment pollution

Abstract

The rapid growth of population in developing country causes environmental contamination by increasing significantly pollution load in  river and other water body. It needs efficient and effective strategy to overcome contamination in certain areas. Technical identification of pollution source and its influence to environmental quality is important to should be known and socialized to community. Land use to is important to get  priority  and should be  managed consistently environmentally sound, beside solid waste and domestic wastewater. Law enforcement also should be applied, especially to company or industry which significantly gives contribution to environmental degradation. Environmental restoration need fund, so government as regulator need partner  from private to overcome environmental problem. Environmentally based industries and services is needed to be developed as government counterpart, but up to now the development of them retarded caused by non competitive interest of commercial bank. Environmental fund should be collected from polluter through regulated mechanism and In the next future  environmental bank should possible manage the fund and finance environmental industry and services to overcome environmental pollution, in this case government act as regulator only.Key words : water polution, management, water resources, strategies

Abstract

Pangkajene archipelago, is archipelago comprising 117 islands scattered in the West Coast District Pangkajene. The islands were inhabited by populations ranging from 10 to 250 heads of families. Most of the population livelihood as a fisherman. To support the daily basic needs are still supplied from the mainland, including the need for clean water. Community water needs during this time a lot depends on rain water that collected or from shallow groundwater. In line with population growth, water demand increases, so frequent water shortages, especially during the dry season. Sea water treatment technology with reverse osmosis systems is an alternative to the settlement of water shortage on the island, but because the number of islands many, it will be difficult to meet the needs of water in a short time. Therefore chosen the middle position of the three islands (Cakdi Saroppe Island, Island and Island Sanane view) as a distribution center. Installed capacity for each of the islands is 10 m3/day, which can serve to the needs of drinking water a thousand people. Water treatment technology with reverse osmosis pretreatment consist of the form of multi-media filter consisting of silica sand, zeolite, and activated carbon, followed by cartride filter and a reverse osmosis membrane. Construction of the water treatment unit involves people since it began surveying best location, construction, training and initial operation. Water that has been processed can drink for everyday purposes, therefore, to support the operations of the water is sold to the public for replacement of operational money. The biggest cost needed to produce water is the cost of fuel. By managing the sale of water expected operating costs can be met and comunity get drinking water at an affordable price.Keyword : dringking water, reverse osmosis, society engangement.

Abstract

In big cities, the water quality of rivers used as the main raw water sources is getting worse and worse. That is caused by a lot of improper wastewater management systems, especially in industrial and settlement areas. As an example, the raw water of PDAM TKR Bojong Renged which is taken from Cisadane  Rives contains Ammonia 3.8 mg/l and it means that the content is not allowed to be used as the raw water for drinking water purpose. To cope with the problem, a bofiltration process can be used as one alternative to reduce Ammonia till the required standard quality.  A honeycomb tube type made plastic was the media of biofilter reactor. Operational condition was varied with HRT (Hydrolysis Retention Time) between 1-4 hours and air supply between 0-30 l/minute. The best process condition was found at 2 hour-HRT and 20 l/minute air supply and the Ammonia removal efficiency was about 65%. The linear regression equation was  ya  = -91.19xa + 77.12, where Y is for removal efficiency and the axis X is for Ammonia loading.  Keywords:  raw  water quality, ammonia, biofiltration, honeycomb tube, removal efficiency,

Abstract

Waste to energy now become one of the technology solution that is in many developed  countries, in an effort to reduce greenhouse gas emissions from waste. Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved.Key Words : Solidwaste, Metana, Cell System

Abstract

The total population Bontang in 2014 is around 187,346 peoples. With the level of domestic water demand of 110 liters /person/day, the water needs of the city for at least Bontang 238.52 liters/sec. Currently for the needs of the community water supply received from the local water company with a capacity of 80 liters/sec, and It will be developed further to 250 liters/second in 2015. There are two big industries that need huge of water, namely LNG and Fertilizers Factory.  Factory of East Kalimantan (PKT) need additional water supply around 1000 m3/h or (166.67 liters/sec) with the specifications for the Water Industry   and 200 m3/h will be used to supply the needs of water for 21 818 inhabitants. Bontang city water source can be derived from groundwater, rivers, and rain water storage (reservoirs of water). In recent decades Bontang relied upon groundwater for water supply industry and some communities, the rest use river water and rain water tandah. With a very heavy rainfall (> 2500 mm / year), then the making of ponds in large quantities can help to reserve water in the future. For the purposes of future water supplies, it would require an asessment of all potential water resources utilization and planning for the use of adapted to the urban development plan. Water recycling of domestic waste is also a potential source of fresh water in the future, especially for industrial use. The drainage system needs to be directed at a large holding pond located in a low area, before going into the sea. The rain that fell in the city drained and collected would be of potential if utilized. In short-term utilization of water of the Bontang river is very of potential, given its location in the city center and is one of the many watersheds in Bontang, causing floods in the rainy season. Control and management of water is needed to support the use of river water.Keywords: Water resources, Water Demand, Water Supply, and Water Balance

Abstract

Slow Sand Filter Technology is very common water technology that is used inmany villages in Indonesia, because very simple, low operating and lowinvestment cost. Sarpalam is the acronym of Saringan Pasir Lambat (Slow SandFilter). For optimal process, the system should meet with the standard design forSlow Sand filter. Somba is one village that is situated in Northern Part of SouthSulawesi. In that village there is a Slow Sand Filter with 5 l/s capacity to servearound 5.000 people. The problem is the quality of water is very low, turbid andsmell. The source of water come from the hill, in the eastern part (around 3 kmup hill). After investigation founded that, the system is not meet with standardSlow Sand filter and need modification for increasing the quality of product water. There are some constrain in the modification of the system, namely : existing construction, lack of space in the hill, stability of land, and quality of product water.

Abstract

Wastewater treatment of a combined anaerobic-aerobic system is secondarywastewater treatment after physical treatment. Basically this wastewater treatment relies on bacteria in degrading pollutants. The use of honeycomb biofilter is to increase specific surface of media for attaching bacteria. Total volume of reactors is 280 liter, made of glass, equipped with two circulating pump and blower in the aerobic zone. The Biofilter is made of plastic, structurally like honeycomb. Its dimension is 28 cm x 25 cm x 30 cm, very light and easy to clean. It takes 14 days for seeding.The reactors were run in four different resident time, namely 7 days, 5 days, 3 days and 1 day. The raw water used in this experiment is wastewater from tofu and fermented soybean cake industries that have BOD around 300 - 500 mg/l. The water is sampled weekly and the results from 1,872 physical and chemical parameters from 144 water samples show that the reactors that using biofilters have better performance than the reactors using no biofilters. The Efficiency process in decreasing BOD value is around 51 - 91 % for resident time one day up to 7 days. Besides such a good relatively high efficiency, the hydraulic loading is around 0,48 - 3,33 m3/m2/ day and BOD loading is around 0, 20 - 0,43 kg BOD/m3/day.
