Abstract

This study aims to determine the relationship between social media and the argumentative paragraph writing skill of Politeknik Negeri Batam students. This study employs a descriptive method, with 70 students as the research subjects. In this study, students were asked to do a practice in the form of writing an argumentative paragraph. An analysis from the obtained data is then conducted to find out their mastery in composing a paragraph. As the basis for the assessment, scores in unity, coherence, and development aspect were assigned to each paragraph. These three aspects were then collected and summed up to find the mean of the data, which had been grouped and assigned score before, to determine their mastery level in writing an argumentative paragraph. Subsequently, the data were inserted into a table. Based on the table, which recapitulates the mastery level in writing an argumentative paragraph, the results are as follows: 43 % of the students have a high level of mastery, with 58 % of them having access to social media; 37 % of the students are in the medium level of mastery, with 28 % of them having access to social media; 20 % is in the low level of mastery, with 13 % of them having access to social media. The results of this study show that students who are active in social media have the ability to write a good argumentative paragraph. This might be due to the fact that activities in social media enhance their writing skill, which is closely related to the four aspects of language competencies, which consist of observing, reading, listening, and writing.

Abstract

In order to write an abstract that appeals to a broader audience, it is important to understand the vocabulary used in the context. By identifying words used in the abstracts of undergraduate thesis from Politeknik Negeri Batam students and comparing them with those used in other academic writings, this research attempts to show that developing student’s awareness of academic writing genre is critical for their progress. The data were taken from the abstract section of undergraduate thesis of Politeknik Negeri Batam students published in 2018, which were compiled into a corpus. From the corpus, the keywords and word profile would be identified, which could then be compared to other corpora. Two word lists (New General Service List and New Academic Word List) were selected as the level lists in carrying out word profiling during the analysis. The results show that the students lacked the necessary words and had not yet recognized the genre of academic writing.

Abstract

Washing hands is something that is always urged to be done lately. This pandemic makes washing hands a habit that must be accomplished before and after doing activities. Automatic hand washing is one way to reduce the spread of the virus because it can be used without having to touch the device directly. The development of automatic tools for washing hands is the crucial need for an alternative power source that is fuel-efficient and uncomplicated in terms of maintenance. The eco-friendly electrical source is needed to be implemented to reduce the electricity bills such as using the solar panel as the alternative power source. As an effort to support handwashing activities, the procurement of solar panels as a source of electrical energy is expected to be able to provide simple solutions to prevent the spread of Covid -19 and to make the environment clean and energy-efficient.

Abstract

The Covid-19 pandemic requires elementary and junior high school students to do online learning activities at home. In practice, children interact more often with their gadget during online school hours and outside these hours. Its a concern for most Graha Nusa Batam community residents because the children there are already starting to have symptoms of gadget addiction. Against this background, Batam State Polytechnic (Polibatam) held a robotics technology workshop program for children aged 8-15 years. This activity aims to increase children's understanding of robotics technology, which includes electronics and mechanics. In addition, this activity provides several benefits, namely: being an attractive alternative for children to reduce playing with their gadgets; provide children's experiences in problem solving, creativity and collaboration; and include field experience for Polibatam students by applying the knowledge gained through Project Based Learning (PBL) for the benefit of the community.This workshop held four meetings (March to April 2021) at the At-Taqwa Al-Qur'an Education Park (TPA) building, Graha Nusa Batam housing. The robot used is an analog line follower. Pre-test and post-test were conducted to measure the increase in participants' understanding of the material. This test shows that participants' knowledge of robotics technology can increase up to 25% for participants aged 8-11 years and 22% for 12-15 years.

Abstract

Abstract Heat exchanger is a device used to transfer thermal energy between two or more fluids at different temperatures. This study aims to develop an efficient shell and tube heat exchanger design that is accompanied by an increase in the overall heat transfer coefficient on the shell and tube sides simultaneously. This study focuses on the impact of using helical baffles and twisted tape inserts technology on the total heat transfer coefficient (U) and pressure drop (ΔP). This study analyzes the effect of employing helical baffles on the shell side and twisted tape inserts on the tube side, with optimization using the Genetic Algorithm (GA) method. The independent variables considered include the helical baffles angle (β), the spacing between baffles (Lbc), the thickness of the twisted tape (δ), and the half-pitch of the twisted tape (H). The optimization objective function for both the shell side and tube side is to maximize the overall heat transfer coefficient, while the restriction is that the pressure drop must not surpass the starting design data value. In this study, the E-1-06 heat exchanger was successfully modeled. The modeling data showed only slight differences between the modeling results and the initial data sheet. The deviation value of the overrall heat transfer coefficient (U) = 0.06%, ∆Ps = 0.00%, and ∆Pt = 0.06%. Optimization of the E-1-06 heat exchanger was also successful. Optimization in this study was able to increase the U value by 3.97%, while the ∆Ps value decreased by -2.01% and ∆Pt by -19.11%. The findings indicate that the modified design is capable of enhancing thermal performance without compromising hydraulic efficiency, thereby demonstrating its potential for application in energy processing systems and industrial cooling.AbstrakHeat exchanger adalah perangkat yang digunakan untuk menyalurkan energi termal antara dua atau lebih fluida pada suhu yang berbeda-beda. Penelitian ini bertujuan untuk mengembangkan desain heat exchanger shell dan tube yang efesien yang disertai dengan peningkatan koefisien perpindahan kalor secara keseluruhan pada sisi shell dan tube secara bersamaan. Penelitian ini berfokus pada dampak penggunaan teknologi helical baffles dan twisted tape insert pada koefisien perpindahan kalor total (U) dan penurunan tekanan/ Pressure drop (ΔP). Pada awalnya heat exchanger ini menggunakan teknologi segmental baffle pada sisi shell dan plain tube pada sisi tube, kemudian desainnya dimodifikasi dengan teknologi yang berbeda, desain pada sisi shell digunakan teknologi helical baffle sedangkan pada sisi tube digunakan teknologi twisted tape. Metode optimisasi yang digunakan adalah Genetic Algoritm (GA). Variabel bebas yang digunakan untuk melakukan optimisasi pada sisi shell adalah sudut helical baffle (ß) dan jarak antar baffle (Lbc) yang ada dalam heat exchanger. Sedangkan variabel bebas yang digunakan pada sisi tube adalah thickness of twisted tape (?), dan half pitch of twisted tape (H). Fungsi tujuan (objective function) optimisasi pada sisi shell dan sisi tube yaitu koefisien perpindahan panas secara keseluruhan (overrall heat transfer coefficient) yang maksimal dan constraint pada optimisasi ini yaitu penurunan tekanan (pressure drop) yang besar nilainya tidak boleh melampaui nilai dari data awal design. Pada penelitian ini heat exchanger E-1-06 berhasil dimodelkan. Data permodelan menunjukkan hanya sedikit perbedaan antara hasil permodelan dengan data sheet awal. Nilai deviasi overrall heat transfer coefficient (U) = 0.06%, ∆Ps=0.00%, dan ∆Pt= 0.06%. Optimisasi Heat exchanger E-1-06 juga berhasil dilakukan. Optimisasi pada penelitian ini mampu menaikan nilai U sebesar 3.97%, sementara nilai ∆Ps mengalami penurunan sebesar -2.01% dan ∆Pt sebesar -19.11%.
