Abstract

Kualifikasi prosedur pengelasan WPS (Welding Procedure Specification) dibuat untuk memberikan panduan bagi juru las atau operator las dalam melaksanakan pengelasan yang memenuhi persyaratan standar dan kode. Parameter serta data hasil pengujian dari pengelasan yang dilaksanakan berdasarkan WPS dan dicatat sebagai PQR (Procedure Qualification Record). Tujuan dari penelitian ini adalah untuk mengetahui apakah hasil test coupon dari PQR yang telah melalui WPT (Welding Production Test) diterima berdasarkan kode dan spesifikasi proyek. Welding Production Test yang dilakukan menggunakan proses SMAW (Shielded Metal Arc Welding) dan SAW (Submerged Arc Welding) dengan ukuran spesimen pelat S420 G2+M Z35 tebal 70 mm panjang 700 mm dan lebar 600 mm. Metode pengujian yang akan dilakukan mengunakan uji NDT (Non-Destructive Test) dan DT (Destructive Test). Pengujian NDT yang digunakan yaitu visual inspection, Magnetic Particle Test (MPT) dan Ultrasonic Test (UT). Pengujian DT yang digunakan yaitu tensile test (transverse), bending test (side bend), impact test, hardness test (vickers), dan macro test. Pengujian menggunakan kode standar AWS D1.1(2015) dan Client Specification F2-FOU-CON-SMO-PL-QA-00024. Hasil Pengujian Spesimen NDT dan DT yang dilakukan tidak ditemukan diskontinuitas pada hasil pengelasan dan diterima berdasarkan spesifikasi FORMOSA 2 Offshore Windfarm Project.

Abstract

The hydroponic pilot project in the Batam State Polytechnic area was motivated by problems with economic conditions and declining health conditions during the Covid-19 pandemic. This project is expected to support the “growing your own food movement” in an effort to reduce unemployment, increase food security and a healthy lifestyle. The hydroponic method was chosen because it is very easy to do and does not require a large area of ​​land. In this community service activity, a hydroponic plant building framework will be made as a prototype of an efficient and efficient hydroponic building so that it can be used by the wider community. This activity is also useful for applying design knowledge as one of the PbL activities carried out by CAD, CNC, CAM, and Fabrication Engineering courses in the Mechanical Engineering Department, so that it can become an arena for higher education participation to support people's lives. The method of implementing this community service activity is to make observations to find a suitable area to build a hydroponic plant house, then the results of the observations are poured in the form of a design by utilizing software so that the materials needed and the shape of the framework that is built can be known. The last activity is making a hydroponic plant place. This activity is planned to be carried out from April to November 2021. Based on the results of the evaluation of the service program questionnaire for product distribution, it is known that the majority of respondents are satisfied with the products produced.

Abstract

Abstract The purpose of this research is to explore the effectiveness of scrabble game in students’ reading comprehension achievement. One class of 7th graders composing 27 students of MTs Jami’iyyah, Pondok Aren, South Tangerang, participated In this as samples. This research applied quantitative method with pre-experimental design of one group pretest and posttest. The instruments used in collecting the data were pretest and posttest. There were 25 multiple choice questions given in each test to be done by the students in 50 minutes. A quantitative analysis was firstly taken before computing the data by using statistical analysis of paired sample t-test. The calculation showed that the average score of students’ reading comprehension post-test was higher (83.77) than in the pretest (56.22). Besides, the statistical analysis indicated that the significant value of 0.01 < a (0.05), thus, Ha was accepted. Referring to the analysis results above, this research concluded that scrabble game was effective media to be used in improving reading comprehension skill of the students.

Abstract

This research was aimed to investigate whether or not Marathon technique gave impact on students’ descriptive writing improvement. This research applied quantitative method with quasi-experimental research design. A total of 40 students of grade 9 of MTs Al-Islamiyah, Ciledug, participated as the samples in which 20 students were in the experimental class and the other 20 in controlled class. Both pretest and posttest were used as the instruments to collect the data. These data were analyzed statistically by using paired-sample t-test. The results of this statistical calculation showed that (t0) > than (tt) = 2.81 > 1.76 in the significance level of 5%. This explained that there was significant difference gained by groups of students taught with and without using Marathon technique. Therefore, this research concluded that Marathon technique affected students’ descriptive text writing achievement.
