AbstrackCooking oil is one food that is very needed by the whole society. The rising price of cooking oil in among society with low economics, is one of the factors causing the repeated use of cooking oil (Waste cooking oil). Using of waste cooking oil can cause poisoning, cancer and others. This research aimed to know the persentage reduction in acid number and water content, also organoleptic of the oil produced. The methods of waste cooking oil can be done by giving antioxidant to the oil. Noni fruit is one of the plant that be rich of antioxidant. 50 gram simplisia of noni added to 250 ml waste cooking oil of packadge and bulk oil. The methods of acid number by alkalimetri and measurement of water content using oven. The organoleptic tests carried out by favorite level from 25 panelists. The results of this research showed that persentage of reduction in packpage and bulk oil’s acid number were 28% and 25%. Whereas for persentage of reduction water content from each oil were 75% and 71.42%. The favorite level of color, odor and flavor were 99%, 76% and 89%. The results of the questionnaire about the feasibility of video in terms of content and appearance was 84.375%, which was included in the excellent category.Keywords: Waste Cooking Oil, Noni Fruit, Water Content, Acid Number and Organoleptic Tests.

AbstractMaking coconut oil was usually done with heating coconut milk for hours until the protein in coconut milk broke and the oil can go out from coconut milk emulsion. The aim of this study was to determine the effect of pineapple juice addition against the amount of produced oil, to determine the quality of VCO enzymatic were density, water content, organoleptic (color, smell and flavor), teacher appraisal on work procedure and product of study result. The variation of pineapple juice shown that more pineapple juice addition then more produced VCO. The mount of produced oil for sample A 80 mL, sample B 83 mL and sample C 85 mL. The quality of three samples were for density which sample A 0.916, sample B 0.938, sample C 0.95. And for water content which sample A0.5, sample B 0.83 dan sample C 1.16. Between three sample, only sample A was accordance with SNI (Indonesia National Standard) No. 7381:2008 which for density was (0.91-0.92) and water content (0.1-0.5%). The teacher appraisal questionnaire about study result and appropriateness of VCO manufacture enzymatic gave cumulative value was 83.20% and it was in very good category.Keyword: VCO (Virgin Coconut Oil), Kelapa (Coconut nucifera L), Enzim Bromelain, Nanas (Ananas comosus L)

AbstractThis research is motivated by the exam questions in the odd semester of 2015/2016 of which items have not been analyzed. Furthermore, the test result of the odd semester is under the minimum completion criteria. This document analysis research is aimed at discovering the quality of question items qualitatively and quantitatively. The result of the study suggests that 40 items of the odd semester chemistry subject exam questions are not qualitatively compliance with all material aspects, constructions, and the language examined from class 10 of Islamic Senior High School Ponpes Khairul Ummah. Furthermore, at MA Nurul Falah, there are 19 items which are not compliance with the aspect of materials, constructions, and the language that is examined. Quantitatively, there are 29 valid items at MA Ponpes Khairul Ummah and possess test reliability as many as 0.65. At MA Nurul Falah there are 31 valid items and possess test reliability as much as 0.76. Keywords: Analysis of grain problem, chemistry, qualitative, quantitative

The present study was encouraged by the low learning outcomes of students at MAN 1 Pekanbaru that were influenced by the lack of students’ participation during learning process and caused teacher-centered learning. This study was a quasi-experimental research with Pretest-Posttest Control Group design. It aimed at investigating the effect of implementing learning model “Guided Inquiry-Based Portfolio Assessment” on students’ chemistry learning outcomes in colloid topic at XI Grade of State Islamic Senior High School 1 Pekanbaru. Afterwards, the samples of this study were students of XI Science 2 class as an experimental class and XI Science 3 as a control class taken through simple random sampling from all students of XI Science classes in academic year 2015/2016 as population. In addition, the data was collected by using tests including homogeneity test as the preliminary data in the previous materials and pretests and posttests as the last data, documentation, and observation. Then, the data were analyzed by using t-test. As the result, it was obtained that tobtained =2.880 and ttable =2.000 in significance level 5%. Therefore, it showed that tobtained ≥ ttable so that Ho was rejected and Ha was accepted which indicated that there was an effect of implementing learning model “Guided Inquiry-Based Portfolio Assessment” on students’ chemistry learning outcomes in colloid topic at XI Grade of State Islamic Senior High School 1 Pekanbaru with influence coefficient 12.5%.

AbstractAcetosolv process is one of making pulp alternative which friendly environmental. Making pulp of banana stem with a solution of acetic acid cooking (CH3COOH) and catalyst sulfate acid (H2SO4) are expected to take place simultaneously, either delignification process or degradation of polisakarida. The variable process is looked in this research is concentration of acetic acid (70%-wt, 80%-wt, 90-wt%) with cooking time (1 hour, 2 hours, 3 hours), whereas constant variabel in this research in liquid to solid ratio (20/1), concentration catalyst (0.6%-wt), and measure of raw materials (±1,5cm). The result of the study exhibit banana stem may become as raw material in making pulp which using acetosolv. Yield pulp around 50.64 % -57.13% with content of lignin pulp 12.5% -19.42%, and content of cellulose pulp 80,85%-82,28%, which is variation according to process. The best condition which produce yield with high cellulose level and low lignin are gotten at concentration of cooking 90%-wt with time of cooking 3 hours. The result shows that banana stem pulp have yield of 50.64%, lignin 12.5% and cellulose 87.49%. Implementation knowledge of student senior high school 1 Tembilahan to exploiting banana stem in making pulp categorized as "very good" because the final results show the percentage obtained 86.78% which lies in the range of 81% -100%, this percentage is in the category of "very good ''. Keywords: Banana stem, Acetosolv, Yield pulp, Lignin, Cellulose, Implementation.
