Published: March 2018

Automobile-service-station wastes make for an acute environmental concern because they contain polyaromatic hydrocarbons, heavy metals, surfactants, and other harmful elements. An eco-friendly way to treat and take advantage of these wastes is embodied in the concept called "valorization". In the present work, valorization is described as a chemical process to remove solids from contaminated water and to stabilize oily sludge into a saponified product. Electrocoagulation and coagulation with aluminum were applied to separate oil-water emulsions and removed 99.7% of turbidity. Both coagulation processes obtained approximately 0.85 kg of treated water and 0.027 kg of dried oily sludge per kg of wastewater. A saponification process with dosages of 10% NaOH stabilized the dried oily sludge. In hopes of finding pathways to valorize wastes, chemical treatments with aluminum and NaOH obtained a product that can be used as a surfactant or as an energy source.Keywords: sludge, electrocoagulation, saponification, oil, wastewater

Regression based estimation or prediction on the stock price can be done traditionally and in a modern way. In this research it is done traditionallywith regard to instrinsic/ fundamental values of the company. Traditionallysome literature uses PER as a model of estimation, but this model have weaknesses if the Analyst or the share owners do not know how to read the financial report or they just trust the numbers on the report. The alternative way to use a model of estimation in this research considered the DER, ROA and ROE variables. This research used a quantitative research. The population of this research is 45 companies. The kind of data used is secondary data. The data analysis used is Double Linier Regression Analysis. The result of the research is the validity test show that the Communality number is higher than Rule of Thumbs in the point of 0,5 (table 4.4) which identifies that the regression equation made do not have multikoliniarity and the regression is able to estimate correctly (table 4.5). it has F-test and it is significant in 0,000, so that it can be concluded that the model made does not have independent variable which influence the dependent one. In this research, the researcher deleted the free variable DER. This is because the researcher wants a model with estimation that can predict as exact as possible. Therefore, the regression equation is: the stock price = 1097.090 + 1141.427 ROA + 5407.516 ROE. The conclusions of this research are, (1) the result of F test shows that the regression model can be used to predict the stock price. In another word, the independent variable consists of ROA and ROE, some or all of its independent variables influence their dependent variable which is the stock price. (2) t Test of ROA and ROE have a positive effect on the ROE stock price. (3) ROA and ROE can explain 86, 7% effect on the stock share.
FENOMENA SURROGATE MOTHER (IBU PENGGANTI) DALAM PERSPEKTIF ISLAM DITINJAU DARI HADIS
Authors: Rahmawati Nurul Alifah , Susilawati Hirma 
Published: March 2018

In this modern era, there is a finding in technology in the field of genetically changes which try to help the married couple with no children for a long time of marriage. This change can be seen in the existence of an infant with infitro fertilization, sperm banks, or magic box that can save sperm and ovum as they are in the real womb. As the time is gone, the practice of infant with infitro fertilization and artificial insemination have developed in some forms of activity which are forbidden in Islam. One of the forbidden forms is infitro insemination or artificial insemination which uses the sperm and ovum from a marriage couple and put it in another woman’s womb. This practice is called as Surrogate Mother. Actually there is no verses in the al-Qur’an which strictly stated about the prohibition on the practice of infitro infant using another woman’s womb (Surrogate mother). But it does not mean that al-Qur’an does not give any solution and also guidance in solving the law of this problem. There are some syar’i theorems that can be used as references in the issue of surrogate mother, for example Q.S Maryam verse 3-5 which give us command to keep praying and trying to get descendents, Q.S al-Baqarah verse 223 which states that a wife is the best place for farming and also hadith of the prophet Muhammad SAW which forbid a man to give his sperm to another woman who is not their wife. Moreover, the practice of this surrogate mother is also contradictory with with al-maqasid al-shariah because it can cause a mixed Nasab. Based on those reasons, the writer is interested in analyzing how is the surrogate mother phenomenon in the view of hadith and its contextualization dealing with the children’s position in the law of Waris (inheritance). Based on the literature analysis done by the writer, it can be concluded that the practice of surrogate mother is forbidden according to Ulama because it gives more mudharat (negative effects) than Manfaat (Positive effect). The hadith used belongs to Hasan hadith with 48,9% percentage. While talking about the child’s position born through surrogate mother, they will be called as adopted children who substitute the position of their own children although they get the sperm and ovum from the real parents.
