Fuzzy logic algorithm and analytic network process (ANP) for boarding houses searching recommendations

Finding a boarding house is usually done manually or by visiting the boarding house in person. Several choices of boarding houses make boarding house seekers have to make choices according to the desired criteria, so it takes quite a long time. A decision support system is a system that can be used to help make decisions based on existing criteria for determining several alternatives to be selected. The methods used in this research are the Analytic Network Process (ANP) and the Fuzzy Logic method. This study employed several criteria in providing recommendations, including distance, price, facilities, security, number of spaces, parking space and convenience. The weighting of these criteria used the fuzzy logic method based on the priority scale determined by the boarding house seekers. This system has provided a recommendation for boarding houses based on the results of the calculation process using the ANP method and weighting using fuzzy logic. The result of calculations shows that the highest value was obtained by Munawar kos (boarding house) with a value of 6.55% and followed by Diding kos with a value of 6.52%

SFL in L2 Writing Teacher Education: A Case Study of an EFL Pre-service Teacher in Conceptualizing Grammar

Abstract SFL in L2 Writing Teacher Education: A Case STUDY of an EFL PRE-SERVICE Teacher IN CONCEPTUALIZING GRAMMAR English education globally has been challenged by an increasing need for academic English practices to support access to content area knowledge and scholarly exchanges. However, EFL (English as a Foreign Language) teachers often lack the linguistic and pedagogical knowledge of how academic texts work to construct meanings in specific disciplines and how to design effective academic literacy instruction accessible to all students. This study, therefore, is aimed at responding to the intensifying demand for academic literacy instruction in international contexts by investigating an EFL teacher’s participation in MATESOL program in North America informed in part by Halliday’s SFL (Systemic Functional Linguistics) and Martin’s genre theory. The study focuses on exploring how this teacher’s conceptions of grammar shifted, if at all, over the courses in the teacher education program and how the teacher’s classroom practice during the first year in her career reflect, if at all, the perspective of language learning. This study is informed by two main conceptions as the theoretical frameworks. First, Halliday and Martin’s social conception of language and language learning serves as the theoretical basis informing the pedagogical knowledge that the teacher develops. Second, a sociocultural approach to teachers’ knowledge development serves as a framework to understand how the teacher conceptualizes a more functional conception of language and language learning for academic literacy instruction in a sustained process of teacher learning with respect to the teacher’s whole lived experiences. This study uses an ethnographic method of data collection and analysis. The data were collected from multiple sources including field notes, instructional materials, audio tapes, email exchanges, interviews, textbooks, and course assignments. Data collection focused on documenting this teacher in conceptualizing of grammar over her participation in the teacher education program and over one year of teaching experience upon completion of her MATESOL program. In analyzing these data, this study involved coding and categorizing processes to generate patterns of themes with reference to the research questions. This study is expected to contribute to an effort of preparing teachers with the expertise of teaching academic literacy and development in international contexts by considering how local contexts shape their pedagogical knowledge development

Regenerasi alami semai mangrove di areal terdegradasi Taman Nasional Kutai: Natural regeneration of mangrove seedlings in degraded area of Kutai National Park

Natural regeneration of seedlings in mangrove forest is an important part of the secondary succession process. This research aimed to analyze the natural regeneration that occured in degraded areas of Kutai National Park, particularly in Bontang and Sangkima. Data collected was the presence of natural mangrove seedlings and measurement of environmental parameter i.e. soil and sea water. Vegetation inventory was conducted establishing plots placed intentionally (purposive sampling) at rehabilitation plot area of Bontang (0,98 ha) and Sangkima (1,04 ha). Composite soil samples were taken from five points in the plots at two different soil depths: 0-30 cm and 31-61 cm. Water samples of 200 ml were collected from the plots. The results of this study showed that at both locations six species of mangrove seedling were found. Bontang area consist of Acrostichum aureum, Scyphiphora hydrophyllacea, Rhizophora apiculata and also Ceriops tagal species. Meanwhile, in Sangkima area species was identified as: Sonneratia alba, Rhizophora apiculata, and Rhizophora mucronata. Distribution of seedlings mangrove at Bontang area has strong positive correlation with environmental parameter of soil texture (silt and clay), soil chemical (CEC, N, C, Na, Ca), tides, and water chemical (salinity, NO3 and COD). In other hand, seedlings distribution in the Sangkima area have strong positive correlation with environmental parameters of soil texture (sand) and water chemicals (Mg, Al, pH, COD, BOD, DO, and TSS). In order to speed up of the restoration in degraded areas of Kutai National Park mangrove forest, it was need attention to suitability aspects of each species based on the environmental conditions of each site

Emerging voice: Exploring the process of teacher-students’ dialogic interaction in mobile instant messaging (MIM) to construct voice in argumentative writing

Despite the growing body of literature on the role of Mobile Instant Messaging (MIM) in supporting educational practice, little comprehensive understanding could be gained on how to scrutinize dialogue between teacher and students in MIM for the sake of students’ meaning-making. Thus, this study explored the process of teacher-students dialogic interaction in a MIM group as a viable pedagogical activity in fostering students’ establishment of voice in argumentative writing. Particularly, it focused on the construction of Engagement resources (Martin White, 2005) as the realization of voice in the students’ writing. To reach the objectives, a qualitative case study with multiple data sources were employed, i.e., the records of instant messaging conversation, students’ argumentative text, interview, and observation. The findings revealed that the teacher-students’ discussions in the instant messaging space were enjoyable activities that could support the students’ awareness of Engagement resources because they allowed the discovery of repertoires through reasoning, problem-solving, and peer learning. Furthermore, although there were various uptakes of Engagement resources in the students’ text, most students showed progressive achievements in applying the sources effectively in their writing

THEME AND THEMATIC PROGRESSION OF UNDERGRADUATE THESIS: INVESTIGATING MEANING MAKING IN ACADEMIC WRITING

This study attempts to investigate the choice of theme and thematic progression deployed in one of the considerably best undergraduate theses in a university in Indonesia. The choice of theme and thematic progression is constrained by the audience of a particular culture; therefore, the process of meaning making is culturally situated. The university, in effects, has its standard for grading academic writing, representing a culture that shapes meaning making processes. This study particularly focuses on how theme and thematic progression contributes to making meanings to meet the demands of the institution. This study employs a descriptive-qualitative research design embracing the characteristics of a case study approach. The data obtained from the best undergraduate student’s thesis were analyzed from the perspective of Halliday’s theme system and its progression. The analysis shows that the three types of theme: topical, interpersonal and textual themes, were realized in the thesis following the conventional features of good academic writings. The topical theme dominantly occupies the theme system chosen for the thesis. This study confirms that a good academic text shares its characteristics across cultures, suggesting that the teaching of academic writing in one culture could refer to the characteristics of good academic texts in other cultures.
