Abstract

Water is a fundamental and essensial need in life. Batam is one of industrial cities that use a lot of refill drinking water. Industry is a potential source of water pollution especially arsenic (As) and Cyanide (CN, it produces pollutants that are extremely harmful to people and the environment. 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. While Cyanide is very harmful to the environment and other living things. The perpuse of this research is to know the content arsenic (As) and Cyanide (CN) in the depot of refill water in Batam. Sample analysis conducted at PT.Sucopindo branch Batam Riau Island-Indonesia. The sampel number of six samples from each district Batam is Salsabila Batam Center, Pak De Qua Tiban, Fun Qua batu Ampar, Fresh Qua Bengkong, Salwa Qua Batu Aji, dan Alam Qua Piayu. The result obtained Arsenic (As) and Cyanide (CN) content of sixth refills depots is <0,0001 mg/L dan <0,008 mg/L. The result of this research showed that all six samples meet the qualification of the Regulation of the Ministry of Health no.492 Year 2010 both arsenic (As) and cyanide (CN).

Abstract

Water needs are very good for humans because they are human body-forming substances. Public awareness of getting water that meets health requirements is increasing. People tend to choose more practical methods with relatively low costs in meeting drinking water needs, especially in the city of Batam. One of the fulfillment of drinking water needs that is an alternative is to use refill drinking water. The source of raw water for drinking water in the city of Batam comes from reservoir water. Water is a source of high fluoride intake. Thus, fluoride levels in water used for consumption must be considered so as not to overdo it. Fluoride is a highly reactive halogen, so it is always obtained in the form of compounds. Inorganic fluorides are toxic and more irritant than organic ones. Chronic poisoning causes people to become thin, disrupted body growth, dental fluorosis and skeletal and digestive disorders that can be accompanied by dehydration. The method used in this study is simple randomized sampling. The standard method of analysis for fluoride parameters (F) is the 4500-F-D method (SPADNS colorimetric method) used in the laboratory of PT. Sucofindo Batam. Laboratory test results of PT. Sucofindo Batam from the six refill drinking water samples taken, namely Fun Qua Batu Ampar, Salsabila Batam Center, Pak De Qua Tiban, Fresh Qua, Bengkong and Salwa Qua Tembesi obtained results of fluoride level analysis of <0.06 mg / L. While the results of fluoride level analysis from Alam Qua Piayu were obtained at 0.43 mg / L. Refill water treatment from 6 locations of drinking water depots based on by Regulation of the Minister of Health No. 492 of 2010 still meets the quality standards set at 1.5 mg / L.

Abstract

Sand mining activities that continue to increase as a result of increasing demand for raw materials for infrastructure development have an impact on the environment. Negative impacts on the environment will occur if sand reduction can not be properly managed. One of the locations that is often used as a sand mining activity is the watershed. One of the river basin areas that contain sand mining activities is the Serayu DAS of Cilacap regency. In this research, the analysis of sand mining impact on physical quality of serayu river in Cilacap regency. Physical parameters measured were temperature, total dissolved solid (TDS) and electrical conductivity (DHL). The measurement results were conducted in 4 stations from upstream to downstream of Serayu River Cilacap Regency resulting temperature value of water between 30oC -31.5oC. The TDS value is in the range of 100 mg / L - 140 mg / L and the DHL value is in the range of 100 μS / cm - 200 μS / cm. Sand mining activities affect the rise of TDS and DHL in serayu river even though the value is still below the quality standard. Keywords: physical quality of river water, serayu river, sand mining

Abstract

Wetland farmers in Maos District, Cilacap Regency were originally all farmers of paddy fields, but the increasing economic need, the farmers began to shift to fish farmes (pond) because the income is hgher. However, this resulted in conflicts over the utilization of water resources for paddy fields and ponds. The research method is deskriptive, databased on interview result both to farmer of paddy field, pond farmer, water user officer and related service in Maos District, Cilacap Regency. The result showed that conflict of utilization of water resources of irrigation in Maos District between wetland farmer and fish farmer (pond) have an effect on paddy farmer production result. Rice production is not optimal because water that should be used for irrigation is reduced to the pond. Maintained capacity of the irrigation network can ensure the water requirements of farmers. The Goverment as a main authorities in management of primary irrigation network, needs to improve its capabilities especially in allocating operational and maintenance funds. To increase paddy production and the welfare of society, policies need to be done first is to increase the irrigation capacity. Keywords : conflict, paddy field, fish pond

Abstract

The use of kepok banana peel activated carbon (AC-KPK) and nipa shell activated carbon (AC-TN) to adsorb phosphate ions in laundry waste has been successfully carried out. Characterization of activated carbon was carried out with SEM-EDX. The results of the morphological analysis showed that the pore sizes in AC-KPK and AC-TN were included in the macropore category. The elemental content of the AC-KPK adsorbent is C 74.9%; 23.6% O and 1.5% K, whereas in the AC-TN adsorbent it was observed that C elements were 70.7%; O 25.5%; K 2.0% and other elements such as Ca, Na, Mg and Cl are contained in small quantities. The optimum contact time needed by AC-KPK to adsorb phosphate ions in laundry wastewater is 15 minutes with an adsorption efficiency of 98.83%, the AC-TN adsorbent is 5 minutes with an adsorption efficiency of 99.52%, and the combination of AC-KPK&AC- TN resulted in a contact time of 5 minutes with an adsorption efficiency of 99.91%. The adsorption kinetics of phosphate ions with the three adsorbent media followed the pseudo second order model with adsorption rates for the adsorbents AC-KPK, AC-TN, and the combination AC-KPK & AC-TN respectively 3.9400 g/mg.min; -28.7119 g/mg.minute; and -10.8895 g/mg.min.
