This study shortens the laboratory service time by shortening the centrifuge time and obtaining serum as an examination material. The research method used was pre-experimental research. The results showed that the average LDH in the blood group centrifuged 3000 rpm 5 minutes was 309.9 U / L and 306.4 U / L centrifuged 4400 rpm 3 minutes in the blood group. In conclusion, there is no difference in serum LDH levels from blood centrifuged at 3000 rpm for 5 minutes and 4400 rpm for 3 minutes.   Keywords: Centrifugation, Lactate Dehydrogenase, TAT

This study was conducted to know the effect of applying Peer Review Strategy on the students’ achievement in writing descriptive paragraph. It was conducted by using experimental research method. This research design was conducted pre-test, post test in experimental and control group. The population of this research was the eight (VIII) grade students of SMP IT IQRA’ Medan. The sample of this research was taken by lottery technique. They were in class VIII-1 by experimental group and the class VIII-2 by control group. The experimental group was taught by using Peer Review Strategy while the control group was given no treatment. The instrument used to collect the data was writing essay test. The data were analyzed by using t-test formula. The result showed that the value of t-observed was higher than the value of t-table. (3,55 > 2,05 (a = 0.05)) with the degree of freedom (df) = 28. It means that there was a significant effect of applying Peer Review Strategy on the students’ achievement in writing descriptive paragraph. So, the alternative hypothesis (Ha) was accepted.

The research aims to examine how positive review disconfirmation (i.e., a positive deviance between a hotel consumer’s poststay evaluation and the average review rating by prior consumers) affects subsequent consumers’ willingness to post online reviews and their own review ratings. By employing an experimental research method, this study reveals that positive review disconfirmation increases hotel guests’ willingness to post online reviews, and increases their online review ratings through the mechanism of concern for others, demonstrating an act of altruism. In addition, comparatively the positive review disconfirmation effects are stronger when the variance of prior review ratings is smaller. This study enhances the online review social influence literature, and the consumer’s altruistic motivation of posting online reviews.

OBJECTIVE: To test a reliable and easily administered frustration-induction procedure for experimental research. METHOD: One hundred volunteers (81 women, mean age ± SD 34.2 ± 8 years) physically and psychiatrically healthy submitted to the frustration induction procedure were prevented from reaching reward level scores. Subjective aggressiveness feelings related to frustration were self-rated in a 13-item visual analogue scale before and after the procedure. RESULTS: Significant increases in aggressiveness-related feelings were detected in 12 of the 13 items. This was consistent with the observed overt behavior of the subjects during the task. CONCLUSIONS: The frustration-induction procedure is a simple, easy to administer frustration-induction procedure that can be used in experimental studies in normal subjects.

Based on the explanation of the theory by Gardner the state is motivation comes from within a person as a driving force to achieve goals for more advanced change. This study aims to determine how enthusiastic student's Eighth grade in the SMPN 03 Bengkulu Tengah are in learning English, especially speaking English. Researchers used a quasi-experimental research method, namely a control group posttest only design which showed a significant difference between 74, 92%, and 61.96% of the experimental class in the control class. From this hypothesis, the researcher obtained a comparison of the experimental class in the treatment using the storytelling method of 4.34% and the control class with the narrative picture method of 3.58%. So the researcher can conclude that there is a significant difference between the two methods with or without the use of treatment compared to the motivation to learn English in class VIII students at SMPN 03 Bengkulu Tengah.

Moringa leaves are one part of the plant which has many health properties one of which is an antioxidant. One of the content of Moringa leaves which contains antioxidant activity is quercetin. Quercetin Is polar and insoluble in air. An experimental research method with a descriptive analysis design, starting with making Moringa leaf maserat, screening, and testing the SPF value, using a UV-Vis spectrophotometer. The purpose of this research was to find out the type of solvent against the SPF value of Moringa leaf maserat. Based on the experiments that have been carried out the methanol (6.75) solvent elds a higher SPF value compared to ethanol (5.32).   Keyword: Moringa Leaf, Solvent, SPF. ABSTRAK   Daun kelor merupakan salah satu bagian tanaman yang memiki banyak khasiat untuk kesehatan salah satunya ialah sebagai antioksidan.

First Time

At this workshop, the transdisciplinary research group H.A.U.S. presented a new experimental research method (TPT) for the first time. Classic methods like “Living Lab” and “Wizard of Oz” are widely used and well established in social robotics research, but they imply explicit limits and raise methodological concerns. The epistemology of TPT’s performances draws on concepts related to Hans-Jörg Rheinberger’s “epistemic thing” and Michel Serres’ “quasi-object”. These theoretical underpinnings are discussed, alongside limitations of TPT and benefits of this approach compared to classic methods.

Here, I employ the practice of making as an experimental research method to reconsider the relational and ethical issues raised in Bone and Blaise’s primary article.

Healing Second degree burns can be affected by the presence of bacteria. This research reveals the role of honey and MEBO in removing bacterial effects on healing. Pure experimental research method with a completely randomized design (CRD). There were 4 treatments, which were positive, negative, honey and MEBO treatment, each of which was given to rats with second degree burns. Wound healing and other parameters were observed on 7 th, 14th and 21st days. The result was that the administration of honey as an antibacterial drug was very effective and gave healing on the 21st day to white rats. Giving MEBO as an antibacterial drug is very effective and provides healing on the 21st day to white rats. Giving honey is more effective than MEBO as an antibacterial drug and healing burns on 21st day against white rats.
