To fulfill the people’s primary need, the government is duty bound to stock remote regions with a steady supply of fresh water. That duty necessitates assasing and applying of appropriate water treatment system in these remote regions or villages. In fact the number of people needing the service is few, and the education level of the people is generally low. Having a small scale and simple water treatment technology would fit this standard. There are many water treatment technology, but only a few should be applied for a minimal capacity production. The applied technology should benefit the localpeople and, in accordance with local’s conditions, long-lasting. This paper will discuss various water treatment technology suitable for a small-scale production. The technologies are selected based on its ability to purify thewater and the cost of each system. The calculations were derived from otherwritten sources along with field data gathered by BPPT. These technology include the coagulation-filtration technology, slow-sand filtration technology, ion-exchange technology, reverse-osmosis technology and the active-carbon technology.

The disposal of hospital waste needs special treatment. To assist the hospital waste treatment of Makassar city, UPT-LSDE, BPPT has been designed and developed a medical incinerator with the capacity of 50 kg/jam at Rumah Sakit Jiwa Dadi Makassar in the year 2002.After one year operation, the system was provided by recuperator and tested to measure the emission characteristics into operation modes. The first mode, incinerator was run without operating recuperator and the second by operating recuperator. Characteristics of exhaust gas emissions were monitor continuously during test by using a poprtable gas analyzer, while particulate sampling was done as standard sampling Method 5 EPA.The test results show that pollution gas emissions, except CO, are under the regulation standard limits of Environmental Control Agency Head Decree No.Kep-03/BAPEDAL/09/1995. While particulate concentration in exhaustgas is under the standard limit of Environmental State Minister Decree No.13/1995. However, waste feeding and air combustion distributor of the tested incinerator need to be modified to achieve optimum combustion.This paper presents the exhaust gas characteristics of the tested unit that was performed on 19 September 2003.

Traditional distillation of akar wangi (Vetiveria zizanioides) using kerosene as a fuel has been used in small industries. The solid waste is burned in open air will emit strong odor which harmful to the environment. In fact, the waste has a caloric value of 3.800 kkal/kg, and by the proper handling, the waste can substitute part of the distillation process energy potentially and can reduce the environment impact caused by incomplete combustion or by the ingredient it self i.e. sulphur oxide and nitrogen oxide. To treat those waste, it is necessary to separate between distillation vessel with the steam generation system.

Surabaya Kenjeran Beach, as a part of Eastern coastal area at East Java, in addition to has function as a sea recreation (a tour) place and fishing, it also estuary for community channel and rivers from city. The condition of Surabaya Kenjeran Beach effected by Hg pollution, had observed by previous researcher, they suggested that water, sediment, and fishes from Kenjeran Beach were already dirtied by Hg at dangerous level. Hg that can be found in industrial waste generally has a inorganic form, but in the water environment, inorganic Hg change into organic Hg by microorganism (for example, methyl Hg) which is more toxic. Fisherman communities is one of the group which have a risk getting effect of methyl Hg, because they usually eat fish from sea that dirtied by Hg.This research plan is case control, in order to studying relations between consumed sea fish and degree of Hg in fisherman’s hair, measuring average degree of Hg in their hair and than compare it with limit value, and also studying healthy disorder sigh that likely appear as a result of Hg poisoning. This research took place at Kenjeran district, Bulak sub district, Surabaya. The number of samples for group who affected by Hg are 70 person and controlled group are 45 person. Respondent’s hair (research subject) was taken and then observed by Atomic Absorption Spectrophotometer (AAS) No Flame.As result, at the fisherman group who consumed sea fish at average 99.11 g/day, they have degree of Hg in their hair is 256.086 ppb. There are no data of consume sea fish at that time for the controlled group, average degree of Hg in their hair is 0.511 ppb. Healthy disorder sigh (subjective symptoms) which is suspicious as a result of Hg poisoning at this research are kidney, lever disorder, headache, painful, tremor, bleeding gums, and visual disorder.Conclusion is, statistically there is significantly relations between consumed sea fish and degree of Hg in hair, and average degree of Hg in the effected group’s hair is higher than the controlled group, but it’s not over limit value that recommended by National Research Council (NRC) is 12 ppm, also there is significantly relations between degree of Hg in hair and healthy disorder sigh (subjective symptoms).
