Study of the Influence the Acidity Level of Sulphuric Acid to Thermal Cracking and Triglyceride Saturation of Crude Palm Oil by Using Two Stages Electrochemical Thermal Cracking

Crude Palm Oil (CPO) was experienced with electrolyze by using two stages electrochemical thermal cracking reactor, zeolyte as catalyst, silver as cathode and cuprum as anode. In this research, we used electrolyte solution for 2 kinds of concentrate which was 40 and 60% of sulphuric acid (H2SO4). It worked in 1 atm with electrolyze for 1 hour, heating till reaching temperature 80oC for 1 hr, fogging process for 1 hr, and heating without electrolyze nor fogging about 30 minutes. From lubricity analyze, this product is a fuel with high lubricity. The analyzer showing that cracking of triglyceride of crude palm oil has same characteristics with diesel

Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui pengaruh faktor-faktor yang mempengaruhi minat mahasiswa bekerja di perbankan syariah. Objek dalam penelitian ini adalah persepsi nilai religius, persepsi penghargaan finansial dan minat mahasiswa bekerja di perbankan syariah. Subjek penelitian ini adalah mahasiswa non pendidikan Fakultas Pendidikan Ekonomi dan Bisnis Univeritas Pendidikan Indonesia. Metode yang digunakan dalam penelitian ini yaitu survei eksplanatori dengan menggunakan angket atau kuesioner sebagai alat pengumpul data, sedangkan teknik analisis data yang digunakan adalah regresi linier berganda. Adapun sampel yang diambil sebanyak 142 orang. Hasil penelitian menunjukkan bahwa persepsi nilai religius (X1) berpengaruh positif dan signifikan sebesar 0,328 dan persepsi penghargaan finansial (X2) berpengaruh positif dan signifikan sebesar 0,279 terhadap minat bekerja di perbankan syariah (Y). Artinya semakin tinggi (baik) persepsi nilai religius dan persepsi penghargaan finansial mahasiswa terhadap perbankan syariah maka minat mahasiswa bekerja di perbankan syariah akan semakin tinggi.;--- The main problem in this researchis the low interest student non education FPEB UPI to work in Islamic banking. Therefore, the purpose in this research is to know what influence of factors which is affect the interests of student to work in Islamic banking. The object in this research is the perception of religious values, perceptions and interests financial awards students working in Islamic banking. The subject of this research is a student of non education faculty of Economics and Business University Education Of Indonesia. The methods used in this research is explanatory survey using a question form or questionnaire as a means of collecting the data, while the data analysis technique used was multiple linear regression. As for the samples taken as many as 142 people. The results showed that the perception of religious values (X1) positive and significant impact of 0.328 and perception financial awards (X2) positive and significant amounted to 0.279 against interest work in Islamic banking (Y). This means, if the perception of religious values and the perception of student financial awards against Islamic Banking is higher, then also the students interest for worked in Islamic Banking will be higher

The data collection method in this study uses a documentation method by looking at and recording relevant available reports. The data analysis technique used is content analysis to draw conclusions from the documents used.Based on the results of the researcher's study on the implications of the concept of Insan Kamil Ibn Arabi on Advanced Islamic education is the essenceof the purpose of Advanced Islamic education, namely the formation of Kamil (Plenary Man) who has Qurani morals, people who have Faith, insight, wisdom and have traits that are reflected in the person of the prophet Muhammad. In accordance with the concept of Insan Kamil according to Ibn Arabi that the human being who can become the place of God's tajaali is a special perfect man (Insan Kamil) that is, a human being who has managed to reach the highest level in the dignity of his humanity, which there is Haqiqah Muhammadiyah or Nur Muhammad in him. In addition, Advanced Islamic education aims to create a kaffah person in the religious dimension and awareness of the duties of a human being as a servant of Allah and as a khalifatullah on earth and is able to become a servant who is advanced and resilien

PEMODELAN DAN PERAMALAN PENUTUPAN HARGA SAHAM PT. TELKOM DENGAN METODE ARCH - GARCH

Adanya heterokedastisitas pada suatu data deret waktu, membuat pemodelan dan peramalan dengan menggunakan ARIMA Box Jenkins tidak lagi valid. Diperlukan metode lain dalam memodelkan heterokedastisitas, sehingga dilakukan pemodelan menggunakan ARCH-GARCH dalam memodelkan volatilitas dari data tersebut. Seperti pada data mingguan penutupan harga saham PT. TELKOM yang diambil pada periode September 2008 hingga Desember 2012, Residual yang diperoleh dari model ARIMA diuji heteroskedasticity dengan uji Lagrange Multiplier (LM). Hasilnya data tersebut mengandung heterokedastisitas yang kemudian dimodelkan dengan GARCH (1,1) untuk memodelkan varians error dan dilakukan peramalan dalam jangka waktu 104 periode ke depan.Kata Kunci: : Time series, volatilitas, heterokedastisitas, Uji Lagrange Multiplier, model ARCH - GARC

Separation of Glycerol from Biodiesel Oil Products Using High Voltage Electrolysis Method

This study aims to separate glycerol from used cooking oil biodiesel products. This research is done by main process by analyzing free fatty acid level (FFA) to know the fat content of the oil in order to know the next process. This research is done by electrolysis process using high voltage. We done transesterification process by using methanol and NaOH as catalyst before performing the process of electrolysis with high voltage. Biodiesel is manufactured using a mini-scale stirred tank reactor (RATB) laboratory. This process is heated at temperature (35-60) oC, the ratio of used cooking oil and methanol (5:1, 6:1, 7:1, 8:1, 9:1) using a 0.1 N NaOH catalyst. The research obtained optimum reaction temperature yield highest percentage of rendement at temperature 60oC and ratio of used cooking oil and methanol 5:1 with percentage of rendement equal to 88,88, cetane number 48,4, kinematic viscosity 2,560, pour point 37,4 oF, flash point 131 oF, Conradson Carbon Residue (CCR) 0.09, and ASTM Colour 1.5. This shows that the manufacture of biodiesel with high microwave and high voltage utilization yields a high percentage of 88.88 and the product is biosolar-48. 

BIODIESEL PROCESS PRODUCTION FROM WASTE COOKING OIL USING MICROWAVES AND HIGH VOLTAGE

Increasing fuel demand has an impact for decreasing fossil energy reserves. One of the government ways to solve this problem is by increasing the production of biomass fuels, for example biodiesel. Biodiesel can be produced from waste cooking oil through the transesterification stage that reacts oil molecules with alcohol and catalyst to produce methyl esters. Heating method that can be used is microwaves method. This method utilizes wave emission which is absorbed by the sample to make sample’s temperature being higher than surface’s temperature of the reactor’s wall. In the process of making biodiesel, there are several factors that affected heating process. There are ratio of waste cooking oil and methanol, an amount of catalyst, reaction temperature, voltage, and distance of electrodes. The effect of that factors can be seen from the result of the biodiesel’s rendement. From this research, we had ratio 5:1 of waste cooking oil and methanol got 85,. % rendement, 2% of catalyst got 87.12% rendement, 60oC reaction temperature got 88.88% rendement, 10 kV got 89.12% rendement, and 1 cm of electrode’s distance got 86.34% rendement. This result suggests that a biodiesel production prototype with microwaves and high voltage utilization can produce a high percentage of biodiesel rendemen
