Transaminase Enzyme and Liver Histological Profile of Mice Administered Extract of Pegagan (Centella Asiatica (L.) Urban)

The purpose of this study was to determine whether pegagan caused toxic effects on the liver. This study used completely randomized design with four treatments, ie 125, 200, 275 mg/kg BW and control, each treatment consisting of six replicates. Variables observed were the level of GPT, GOT and histological profile of liver. GPT and GOT levels were analyzed by analysis of single variant of 0.05. Histological picture of the liver include central venous dilation, inflammation, and damage to the structure of liver cells were performed by descriptive evaluation. Pegagan leaf extract did not show significant effect on GPT and GOT level in the liver of mice, whereas the histology results did not reveal any visible damage to liver cells in each dose. Administration of pegagan extract up to dose of 275 mg/kg BW was safe and would not cause damage to the liver cells

Improving students’ writing skill in descriptive text using “the power of two and four” (a classroom action research with eighth grade students of MTs Irsyaduth Thullab Tedunan Wedung Demak in the academic year of 2010/2011)

Indonesian government has decided that English is a compulsory subject that is taught at school. English contains of four skills that must be studied by high school students. They are Listening, Speaking, Speaking, and Writing. To teach writing for junior high school is not an easy work. It is the task for the teacher to encourage students to learn writing in the language target. He or she should choose the suitable strategy in teaching it. As stated in school-based curriculum, descriptive text is one of genres that is taught in junior high school. In this final project, the researcher chose the power of two and four to improve students’ writing skill in descriptive text. She wanted to know the implementation of teaching descriptive writing using the power of two and four and the improvement of students’ descriptive writing after being taught using the power of two and four. In order to achieve the objective of the study, the researcher designed a classroom action research. The population of this study was the eighth year students of MTs. Irsyaduth Thullab and the subject of this study was 23 students. The classroom action research was done in two cycles: cycle I and cycle II. These cycles consist of four stages: planning, acting, observing, and reflecting. To analyze the data, researcher used descriptive quantitative. Observation data was analyzed descriptively and the test was analyzed quantitatively. The data collections were interview, observation, and test. In this research, the researcher gave a test of their achievements in each cycle. In the first cycle, the average of the students’ achievement was 67.52 and in the second cycle the students got 77.52. The result of research shows that the improvement of students’ writing skill in descriptive text with the power of two and four covers parts, qualities, and characteristics of the objects. The score of writing in descriptive text with the power of two and four are higher than before. One of advantages of using the power of two and four is that the students can produce the result of the objects more easily and accurately

OPTIMASI SEPARASI PADA PEMISAHAN GLISEROL HASIL PROSES HIDROLISA MINYAK KELAPA SAWIT (Elaeis guineensis) (Optimization of Glycerol Separation in the Hydrolysis of Palm Oil Process Results)

Glycerol is one of the important chemicals in industry, especially the pharmaceutical industry, foodstuff, cosmetics, explosives, and others. Glycerol can be obtained by careful evaporation, and then purified by distillation at reduced pressure. Glycerol is soluble both in water and insoluble in eter. Glycerol can be useful for us to synthesis of fat in the body. Glycerol can be obtained from several processes, including the process of refining oil and fat, alcoholysis, enzymatic, hydrolysis and saponification of oils and fats. This experiment aims to determine the best separation process which can be used to obtain glycerol with variations in rotation speed centrifugation. The experimental procedure begins with the process of palm oil hydrolysis using KOH catalyst then glycerol formed is separated using methods sentrifugasii with their speed - respectively 1090, 1375 and 1772 rpm. From the experimental results obtained at the highest glycerol separation process with speed rrpm 1772 as many as 3.5 mL. Separation using centrifugation method when compared with other methods of separation which is the best method. This is because the results obtained are more separation than others

Creative-critical thinking skills can be trained through text writing. One of the relevant texts for developing students' critical-creative thinking skills is exposition texts. This is because the exposition texts contain the opinions of a person who needs to be criticized for his supporting arguments and necessary creative ideas in solving the problem

Analisis permintaan dan perkiraan kebutuhan konsumsi minyak kelapa di daerah istimewa aceh=Analysis of Demand and Estimation of Consumption Need for

ABSTRACT Coconut oil is one of the vegetable fats which is importnat for the daily consumption. At least 13 kg/person/year of coconut oil is needed. For Daerah Istimewa Aceh, in 1987, the amount of coconut oil consumed is only 9.20 Kg/person/year, which means still below the standar requirement. The amount of coconut oil consumed increases up to 5.81%/year from 197710 1987, while supply decreases to 1.93%/year. It means that the supply is not in balance with the increase of the demand Based on this view, the demand and the estimation of consumption need for coconut oil in Daerah Istimewa Aceh is intersted to be studied. The objectives of the research are to study the factors influencing the demand, the extent of the role of the above factors in determining the demand, and to estimate the consumption need in the future. Proportionate Stratified Random Sampling Methods was used in this study. The data were transformed into logarithmic forms and then analysed using Ordinary Least Square Methods. The data were Cross Section Data Result of analysis show that factors influencing the demand of coconut oil were prices of coconut oil, palm oil, fresh fish, total of house-hold income and number ofhouse-hold member. The price elasticity ofcoconut oil demand is -0.9574, it means that the demand is inelastic The cross price elasticities of palm oil and of fresh fish are 0.9611 and -0.4142 respectively. It implies that palm oil is a substitute and fresh fish is a complement for the consumption of coconut oiL The income elasticity of demand is 0,4771, it means that coconut oil is a normal goods and inelastic demand The regression coefficient of the number of the house-hold member with respect to consumption of coconut oil is 0.6461. It is also estimated that the consumption need for coconut oil from 1990 to 1995 in Daerah Istimewa Aceh will increase 3.91% per year. Based on this results, it is suggested that further efforts to increase coconut oil production should always be made in order to fulfill the increasing of consumption need and to pursue the standar determined by the Goverment: Key words: demand analysis -- consumption estimation -- coconut oi

THE SCRAPBOOK FOR THE STUDENTS' WRITING ABILITY AT JUNIOR HIGH SCHOOL (A CASE STUDY AT JUNIOR HIGH SCHOOL)

Writing involves textual tasks like formulating and structuring ideas into sentences, encompassing idea creation, organization, drafting, and revision. In this context, the utilization of scrapbooks as a teaching aid for writing has yielded positive results, introducing a novel method for writing instruction.
