PENGELOLAAN PERPUSTAKAAN YANG BAIK MENDUKUNG PROSES PEMBELAJARAN YANG EFEKTIF DAN EFISIEN

The library is the heart of a school which has a very vital function in supporting the learning process. Therefore, the school library with the ranks of librarians in it, has an obligation to "turn on" the library either through the services provided to visitors, or through other activities carried out inside or outside the library. Through the Institute of Research and Community Service of Nommensen HKBP University, several lecturers carried out community service activities to Senior High School Nasrani 1 Medan carrying out workshops in terms of fostering library management according to the demands and needs of the school . This activity is very important and meaningful, because it can help and better understand in managing in the field of collection procurement, collection inventory, collection classification, and main cataloging. Through this workshop, the librarian will further broaden his knowledge in carrying out his duties in serving students, teachers and other visitors who are registered and not in the librar

PENGARUH MODEL PROBLEM-BASED LEARNING TERHADAP HASIL BELAJAR PESERTA DIDIK PADA MATERI TEKANAN ZAT

This study aims to determine the effect of the problem-based learning model on student learning outcomes in the material pressure of class VIII SMP Negeri 2 Manduamas. This type of research is quasi-experimental, the research sample consists of two classes, namely VIII-C as the experimental class and VIII-B as the control class, each consisting of 30 students. The research instrument is a learning activity observation sheet and multiple-choice objective tests to determine student learning outcomes. Based on the calculation of the t-test of the two parties, the pretest data = 0.05, it was obtained that H0 was accepted, that the initial abilities of the experimental class and control class students were the same. After being given different treatment, the results of the one-sided t-test calculation for posttest data for =0.05 were obtained tcount = 3.80 and ttable = 1.67 with tcount > ttable, then Ha was accepted.

This study aims to determine the effect of discovery learning models on student learning outcomes in class VII heat material at SMP Negeri 2 Manduamas with quasi-experimental research methods and the population in the study, namely class VII SMP students with a total sample of 82 students. The sampling technique is Cluster Sampling. The instrument used was the test of learning outcomes in the form of multiple choice as many as 20. Before being given treatment to the two classes, the results obtained - the average pretest score for the experimental class was 49.63 and the average score for the control class was 49.44. After being given different treatments, the average posttest score for the experimental class was 74.26 and the average posttest score for the control class was 64.26. The results of the posttest data prerequisite test stated that the sample was normally distributed and homogeneous. Then, a one-sided t-test (a = 0.05) was performed with the condition that t count > t table or 4.13 > 1.67. So it can be said that there is a significant effect of discovery learning model on student learning outcomes in heat material for class VII SMP.   &nbsp

PENGARUH KEMAMPUAN SISWA MENGIDENTIFIKASI GAYA BAHASA TERHADAP KEMAMPUAN MENULIS CERITA

This study aims to determine the effect of students' ability to identify language styles on the ability to write inspirational stories. Factors that cause low students' writing skills are due to the lack of students' vocabulary, the difficulty of conveying ideas in writing. and less able to understand the style of language. This study used a quantitative experimental method, with class IX research subjects at SMP N 4 Laguboti T.A 2022/2023, with a total population of 194 students and a sample of 32 people. Determination of the sample using the lottery technique. This type of research design is a pre-experimental design, namely the One Group Pretest-Posttest design which only uses one class for learning. The data collection technique is to give test assignments to students. The results of this study indicate that the activity of identifying language style influences the ability to write inspirational stories, this is evident from the Hypothesis Test which has been carried out with Fcount Ftable or 11.59 2.03. So that Ho is rejected and Ha is accepted

Cyclic Oxidation Resistance of MoSi2 Added FeCrAlTiY Coatings on ST41 Steel at 700oC Prepared by a Flame Spraying Technique

Advanced power generation will be operated at higher temperatures and pressure to achieve higher efficiency and reduce CO2 emission. This may significantly impact the use of carbon steel that previously has been used in boiler fabrication. In this study, a flame spraying technique was applied to develop a highly resistant coating of MoSi2 added FeCrAlTiY on ST41 steel to improve its oxidation resistance. Four variations of MoSi2 concentration as 0, 10, 20 and 30 in mass% were prepared to investigate the effect of its addition on the cyclic oxidation resistance of FeCrAlTiY coating at 700oC for 8 cycles. The phase composition and microstructure of the coating before and after the oxidation test were analyzed using XRD and SEM, respectively. While the element distribution along the coating was characterized using an EDX. According to the results, partially and fully melted particles, oxides and pores are present in the coatings. It becomes more porous with the increase of MoSi2 concentration. The oxidation test results indicate that the FeCrAlTiY with 10 mass% MoSi2 addition exhibits the lowest mass gain (0.217 mg/mm2) compared to that of MoSi2-free coating (0.261 mg/mm2) and FeCrAlTiY coating with 20 and 30 mass% MoSi2 (0.297 and 0.308 mg/mm2, respectively). As the MoSi2 concentration increases, its addition leads to the deterioration of FeCrAlTiY coating oxidation resistance. The results suggest that FeCrAlTiY-10 mass% MoSi2 is the most resistant coating to cyclic oxidation at 700oC in air and can be applied as a protective coating in advanced power generation
