In this case, most of the writers tend to relate one idea to another to make their ideas coherent. This research article is done to investigate the logical connectors used by the writers of research articles, especially the logical connectors of three categories: logical connectors, frame markers, and Code Glosses. These linguistic devices are commonly used by the writers in academic or research articles (RAs). This is a qualitative research using the documents for analysis. These documents are taken from the research articles published in the academic journals which are collected by means of purposive sampling from the discussion sections of the RAs. The instrument used is called Taxonomy of Textual Meta-discourse. The results show that the writers have different strategies in using the logical connectors depending on which point they relate the ideas in the discussion sections. The results are expected to provide the readers with some logical connectors and some perspectives of the strategies of using logical connectors in research writing especially in the discussion sections. It is recommended that the research writers use logical connectors for making the ideas coherent.

An abstract of any journal article is considered the most important part of the whole article itself because it can lead the readers to foresee what the article is about. This paper attempts to explore the textual space of the abstracts of journal articles. It can also reveal the specificity of abstracts writing of different research journals. This study is comparative study, qualitative in nature, and content analysis. The abstracts used as the sample cover two journals: one is Ventura, the journal of economics, business, and accountancy, published by STIE Perbanas Surabaya and the other is Liceo Journal of Higher Education Research, published by Liceo de Cagayan University. They are analyzed using the textual space for exploring how the moves of the abstracts of the two journals are structured. The results show that there are both similarities and differences in these two journals. It can be concluded that a guide of composing the abstract is needed so that the abstracts can be in uniform. Keywords - genre, genre analysis, move, textual space, discourse community

This type of research uses documents of research articles (RAs) for analysis. This research tries to explore the rhetorical moves in introduction sections of academic journal articles with two different discourse communities: Technology and Economics. It also attempts to provide the writers, especially the novice writers with general knowledge of rhetorical moves of two different discourse communities: 10 of technology RAs and the other 10 of economics RAs. These documents are taken by purposive sampling based on certain criteria. Thus, it a qualitative research using documents as the data for analysis that is also considered content analysis. The analysis is based on the genre analysis approach with CARS as the instrument. All inferences are derived from the results based on the CARs. The result shows that there are some differences of CARS adopted by the authors of the two discourse communities. Therefore, it is vital for the writers to pay attention to the rhetorical moves of introductions of these two different discourse communities. The researcher recommends that the prospective writers adopt these CARs for better adaptation to these two discourse communities when expecting to write the same RAs in these two publications.

Sports organizations such as Australian Institute of Sports (AIS) currently monitor fatigue by a battery of tests including invasive techniques that require taking blood samples and/or muscle biopsies, the latter of which is highly invasive, painful, time consuming and expensive. SEMG is non-invasive monitoring of the muscle activation and is an indication of localized muscle fatigue based on the observed shift of the power spectral density of the SEMG. But the success of SEMG based techniques is currently limited to isometric contraction and is not acceptable to the human movement community. This paper proposes and tests a simple signal processing technique to identify the onset of muscle fatigue during cyclic activities of muscles such as VL and VM during cycling. Based on experiments conducted with 7 participants, using power output as a measure of fatigue, the technique is able to identify the muscle fatigue with 98% significance.

The aim of this study is to evaluate the contribution of right motor cortex of the brain in the central motor control of right-sided muscle contraction. EEG/EEG coherence analysis has been used to determine the functional coupling between the right and left motor cortical areas in twenty normal volunteers, during maximum voluntary contraction (MVC) and 50% MVC of right Adductor Pollicis muscle (APM). It shows that the maximum mean coherence values were: 0.751 during MVC at 10 and 12Hz, and 0.274 during 50% of MVC at 22 Hz. The minimum mean coherence values were: 0.716 during MVC at 48 and 50Hz, and 0.242 during 50% MVC at 34 Hz. The high coherence values obtained during MVC, and to a lesser extent during 50% of MVC, could be attributed to the need of recruitment of both motor cortical areas during the decision phase of central motor control of voluntary muscular contraction. The "will" to perform maximum voluntary contraction could be a major factor, which contribute to the higher coherence values obtained during MVC than these associated with 50% of MVC.

Not only teenagers experience enjoyable and comfort there, but also adult people feel the same too. This phenomenon are happening right now. Seeing this situation, it would be better if the activity of drinking coffee that was liked by the general public could be a way to overcome boredom in learning English, especially in speaking skills. However, not all students can get these facilities due to economic factors. They are called "Underprivileged Students". So, with this activity, it is hoped that it can help disadvantaged students so that they can get additional English education. The ranking shows that the English ability of the people in Indonesia is in the very low category. Without exception, teenagers or students in Surabaya. Especially those who experience this problem are underprivileged students, because they only get education through formal schools which are only carried out in class or online so they are less effective. As stated in the sub-chapter description of partner problems, there are solutions to overcome problems with partners. One of the creative ideas that can be done is to learn English at the Coffee Shop. This activity will take place through 4 stages, the first is pre-activity, the second is the general stage which includes the inauguration of the activity, the third is the core of the activity, and the fourth is the evaluation of the activity.

Education is still a serious concern in each region in order to increase. The quality of education at the Integrated Early Childhood Post (PPT) Kuncup Melati Surabaya is quite good but still needs to be improved. One of them is in technology-based English learning. Learning English at PPT Kuncup Melati Surabaya will be much more interesting if it is packaged with a blend of technology and presented to Early Childhood Education students in the form of visual learning. In addition, online learning is currently being promoted again along with the increasing number of Covid-19 victims during this pandemic. Mastery of technology-based English learning at PPT Kuncup Melati Surabaya is still minimal. This is evident from the learning that is still carried out faceto-face, even though it is carried out in alternating schedules. Even though there are clear rules from the government that suggest that learning is done online. As a solution, assistance is needed in technology-based online English learning with a variety of methods and is carried out in a sustainable manner so that learning can be done online but still interesting. By applying the flipbook application in learning English, it is hoped that it will stimulate Early Childhood Education students in learning technology-based English. Flipbook is a powerful software application designed to convert PDF files to pageturning digital publications. With the flipbook application, a digital bookshelf can be created from several E-Modules that have been produced so that teachers and students can choose which E-Module to read by simply pressing the click button to select it. This Community Service (PKM) activity plan is focused on implementing an interactive English E-Module with a flipbook application for Early Childhood Education students at PPT Kuncup Melati Surabaya. The target of this PKM activity is the students in the school. The expected output is to apply a flipbook application to students at the school and to create a digital literacy corner and e-learning regeneration which is expected to be able to increase the knowledge, skills, interests and motivation of Early Childhood Education students in learning English. With the digital literacy corner, it is hoped that it can increase student interest in literacy.

Parents of millennial generation children must have excellent digital literacy skills so that they can accompany children to learn according to their times. The concern is whether this digital technology can be used properly or will create new, more extreme problems in children's lives. Children learn digital media with parental assistance, but in reality, many parents are careless and let their children play digital media, namely smartphones freely without supervision, because parents are busy working or do not have time to accompany digitally literate children. So from this problem, it is necessary to give understanding to parents that the importance of parental assistance in the process of digital literacy children. Many parents complain that their children become aggressive, angry, crybaby and want to play their own s...

Parents of millennial generation children must have excellent digital literacy skills so that they can accompany children to learn according to their times. The concern is whether this digital technology can be used properly or will create new, more extreme problems in children's lives. Children learn digital media with parental assistance, but in reality, many parents are careless and let their children play digital media, namely smartphones freely without supervision, because parents are busy working or do not have time to accompany digitally literate children. So from this problem, it is necessary to give understanding to parents that the importance of parental assistance in the process of digital literacy children. Many parents complain that their children become aggressive, angry, crybaby and want to play their own s...

A representative building is used in simulation to calculate the panel capacity that can be produced by a roof mounted PV with grid-connected system. It was found that about 10,353 m 2 of roof top of the university buildings could be used for panels installation. The total capacity of the panels is about 2,030 kWp or 2,03 MWp. The capacity consists of four roof directions, i.e., 630 kWp, 535 kWp, 668 kWp and 553 kWp respectively for NE, SE, SW and NW roof directions.
