Abstract

This article reports on a case study designed to examine the implementation of flipped classroom in the EFL classroom in Taiwan. In addition, students’ perception of flipped classroom was also investigated. Sixty-one senior high school students participated in this study; data were gathered from students’ English midterm exam score and questionnaire. The data then were quantitatively analyzed by using T-test and descriptive statistics. The results show that students’ English proficiency in flipped classroom was not significantly different with students in traditional classroom. However, the results reveal that students’ perception of flipped classroom were generally favorable. Students’ contended that flipped classroom enhanced their motivation in learning English, as they liked the self-pace through the course and they stated that flipped classroom gave them more class time to practice English. The results presented here may facilitate improvements in the implementation of flipped classroom in EFL class. Furthermore, suggestions for further research are also presented.

Abstract

The terror of the deadly COVID-19 pandemic that is happening right now becomes more and more intimidating with the rapid circulation of information in massive quantities about this outbreak. Of the various news coming out every day, some are valuable, others might be less useful. However, some of them may cause more harm than good. The problem is how to sort the incoming information and determine whether it is reliable. In this community service project, a public service announcement will be produced with the intention of informing the public about some rumors and misconceptions that have been spreading in society. It is hoped that the announcement will unravel the truth and clear any confusion that is happening. The content of the announcement is based on the Myth Busters page on the official WHO website. It will then be broadcasted by Batam TV. To find out how the viewers perceive the public service announcement, an online survey is conducted, which can be accessed by the viewers by scanning the QR code displayed at the end of the announcement. The results of the survey show that most viewers consider the announcement easy to understand, useful, up to date, and motivating, in addition to having a good mix of attractive colors and clear sound. However, public service announcements on local television channels are no longer the main source of information for citizens of Batam, especially in the context of COVID-19.

Abstract

Tests for determining the elemental composition of stainless steel (SS) in the weld metal and Heat Affected Zone (HAZ) were carried out using the Non-Destructive Evaluation (NDE) Positive Material Identification (PMI) method with X-ray Fluorescence (XRF) technology. This study aimed to identify the chemical composition of metals using the PMI method with XRF technology as a determinant of the feasibility of the stainless-steel materials tested, namely SS 316 and SS 2205. The results of the tests were then matched with the applicable standards, namely ASME Section II Part A for pipe materials and ASME Section II Part C for welding electrodes. The measurement results show that SS 316 with welding electrode grade ER 316 all parts of the object of inspection fall within the standard range used except for material 4, which is the connection between the flange and elbow is declared rejected because the values ​​for Cr, Ni, and Mo do not fall within the standard range. Meanwhile, SS 2205 with a welding electrode grade of ER 2594 shows that all parts of the object being measured meet the requirements of the standard range used.

Abstract

Abstract—The natural charm of the small islands in Kepulauan Riau can definitely spoil visitors’ eyes and attract their attention to visit these islands. Pulau Mubut Darat, which is located in Sembulang, Batam, Riau Islands, has become one of several choices of beach tourism areas. However, in the management of tourist sites, the community and managers in particular have not been able to implement ideas and supporting facilities to satisfy the tourists who come to visit so the tourist area of ​​the island of Mubut Darat began to lose competitiveness with other areas. The observation results of the Politeknik Negeri Batam community service team found several ideas that could help improve promotion and tourist attraction on Mubut Darat. One of them is by making a location plan or POI information sign in the Mubut Darat area. The method of making this sign begins with taking pictures of the entire Mubut Darat island. Then, the location points of each building and the facilities available in each area will be mapped and labeled. With the information signpost of the location plan or POI, tourists will get complete information about Mubut Darat. The location plan or POI information sign is expected to be part of the tourist photo icon on Mubut Darat which can promote and attract of tourists to come.

Abstract

Welder qualification is the qualification of a welder or welder that aims to prove the quality of the welder, which is carried out following the rules in international codes/standards such as AWS, API, ASME, ISO, and other codes/ codes/standards. The purpose of this report is to design a welder qualification scheme using three codes/standards at once, namely: AWS D1.1 (2020), ASME Sec. IX (2019) and ISO 9609-1 (2017). Thus, it can minimize costs, time, and the preparation needed to qualify the welder. The methodology used was a literature review to get the similarity of the variables, which will later be used to qualify the welder using the three codes/standards used. After obtaining the required variables, the next step was the implementation of these variables to qualify the welder from the material preparation and welding process to test the weld results. In order to qualify the welder with three codes/standards at once, it was necessary to pay attention to the relationship for each variable used to cover one code with another. If one of the variables cannot be met in one of the codes/standards used, then the welder's qualification using three codes/standards cannot be implemented. The material used in this welder qualification is ASTM A106 Grade B with a material length of 170 mm × 170 mm with a thickness of 18.26 mm and a diameter of 6" (168.3 mm) sch 160. The test methods used were Visual Inspection and Side Bend Test with four samples.

Abstract

Stress relieving is a heat treatment process that aims to eliminate stress on the end of the material that has been deformed, either internal deformation (swaging) or external deformation (expanding). This treatment aims to eliminate residual stress or residual hardness resulting from the end-sizing process and restore the stress level in the pipe due to the swaging process by heating the material according to the temperature and formation of the material itself. While swaging is a forging process on the pipe cylinder to reduce the end of the pipe, as well as forming the end of the pipe according to the request of the customer, both internal and external deformation processes. This study aims to compare the hardness value of pipe material in non-swaging, swaging, and swaging + stress relieving treatments. This test uses carbon steel material grade L80 pipe size 3 ½ inches with a pipe length of 6 ft. The pressure applied during swaging was 2,850 psi for 30 seconds, with a swage stroke value of 118.00 mm. While the stress-relieving treatment is given heating in the temperature range of 595oC – 625oC with a soaking time of 60 seconds. Of the three treatments, the highest hardness was obtained from the swaging process with a value of 19.2 HRC while the lowest hardness was shown by the non-swaging specimen with a value of 16.7 HRC.
