Abstract

Winterizing is a limited form separation of saturated fatty acids and unsaturated fatty acids, to remove wax and fat has a higher boiling point. To obtain the product specifications, parameters must be control is cloud point ≤ 7 oC. Response surface method use as a tool to determine the optimum operating conditions in the process of winterizing, the control parameter C16 feed composition, temperature, time. Feed C16 varied 19%, 20%, 21%, temperature varied 10 oC, 10 oC, 11 °C, time varied 14 hours, 14,5 hours, 15 hours for order I and central composite disgn in order II. The results showed feed C16 and temperature are significantly influence the cloud point. Model is Y = 6.920 + 1,429X1 0,636X2 + 1,030X22 1,080X12 - 0,650X1X2. Winterizing process optimization point C16 feed obtained 19.20% and temperature 9.93 oC.

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

Solanum ferox or acid aubergine plants is one type of vegetable used as flavoring in food. Solanum ferox contains terpenoids, steroids, flavonoids, alkaloids and phenolics. Solanum ferox has antipyretic, antirheumatic, anti-asthma, antiviral and as a drug for syphilis. The purpose of this study is to test the antibacterial activity of leaf methanol extract of Solanum ferox plant. Leaf Solanum ferox is extracted using methanol. Methanol extract was tested for antibacterial activity using diffusion method to use E.coli, S.aureus and B.subtilis bacteria. Amoxicillin is used as a positive standard while negative controls are solvents used to dissolve samples. Antibacterial activity of methanol and amoxicillin extract showed inhibitory zones of E.coli of 7,72-11,67 mm and 19.97 mm, inhibitory zone to bacterium B.subtilis only at 5.7 μg/mL concentration of 11,29 mm and amoxicillin 18, 51 mm.

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.
