There are still many students who have difficulties in learning fractions, because instructional is often delivered with abstract which is dominated by formal methods. Therefore, a new approach is needed, accompanied by adequate learning media to overcome the problems mentioned above. A realistic mathematical approach with the help of fractional puzzles was designed to help students to explain the abstract situations of a problem into a realistic form then developed to direct students to mathematically search solutions. The place of this study was in SD al Muslim Tambun with the research subjects of the fourth grade students of Ibnu Rusyd 2015/2016 Academic Year as many as 28 students. This is a Class Action Research with 2 trial cycles. The data was analyzed by comparing conventional techniques without learning media with realistic mathematical approaches with the help of fractional puzzles. The results shows that in the first cycle experiment there was an increase in the average value of learning outcomes of 15.64% with an average grade of 75.4. Then in the second cycle experiment there was an increase in the average value of student learning outcomes by 23.31% with an average grade value of 80.4. It can be concluded that the realistic mathematical approach with the help of fractional puzzles can increase the value of student learning outcomes in fraction addition material with the same denominator in elementary school.

The current pandemic study has not been much discussed, especially one focusing on interpersonal metadiscourse markers and appraisal use. Consequently, this study is significant in reporting the descriptive analysis of the features of interpersonal metadiscourse markers and appraisal appearing in the BBC News reports that discussed Corona Virus. A discourse analysis approach is used to examine the interlocutors' phenomena of metadiscourse within the discourse. The study results revealed that the way the speaker delivered the argument was denoted by the presence of interpersonal metadiscourse markers to convey a message. Thus, it demonstrated the way the speakers attempted to engage the listeners in the discourse. Moreover, the findings also revealed that the appraisal framework's application contributed to the markers formerly being analyzed. Consequently, it elucidated how the speaker delivered their arguments by applying evidential, hedges, boosters, attitude markers, and self-mention.

High rise buildings can be a safe place for activities when protected by a reliable fire protection system. Fire safety studies are generally focus on active and passive fire protection systems, life-saving and fire evacuation in a building. This study aims to examine fire protection systems from the fire safety officers' perspective as an important part to ensure that the protection system can function properly and as an initial responder to fire. This study concludes the needs of fire safety officer in a multi-storey building that absolutely necessary as an element of managing the fire protection system and as an initial responder of fire to minimize the impact of property losses and casualties.

Penelitian ini bertujuan untuk mendeskripsikan efektivitas pembelajaran kelompok produktif program studi teknik komputer dan informatika yang menerapkan KTSP pada SMK Negeri ditinjau dari: 1) kelengkapan dan kesesuaian perangkat perencanaan pembelajaran; 2) proses pembelajaran, 3) penilaian pembelajaran; 4) respon peserta didik terhadap kegiatan pembelajaran; dan 5) hasil belajar peserta didik. Jenis penelitian adalah penelitian survei dengan populasi penelitian dua SMK Negeri di Kabupaten Hulu Sungai Utara. Berdasarkan hasil analisis dapat disimpulkan bahwa pembelajaran kelompok produktif teknik komputer dan informatika yang menerapkan KTSP sudah efektif. Hal ini juga dilihat dari aspek berikut ini. 1) Hasil telaah kelengkapan dan kesesuaian perangkat perencanaan pembelajaran kelompok produktif baik silabus maupun RPP yang dikembangkan oleh guru berada pada kategori baik. Penyusunan dan pengembangan perangkat perencanaan tersebut sudah mengacu pada standar isi, standar kompetensi lulusan dan sudah sesuai dengan langkah-langkah maupun format KTSP. Namun masih dapat ditingkatkan khususnya pada aspek pengidentifikasian materi pembelajaran, perumusan pengalaman belajar, perumusan indikator pencapaian kompetensi, dan bentuk penilaian yang akan digunakan. 2) Hasil observasi proses pembelajaran berada pada kategori baik. Dengan demikian, proses pembelajaran dapat dikatakan telah sesuai dengan langkah-langkah yang ada pada standar proses. Namun masih dapat ditingkatkan pada aspek penerapan materi terhadap kehidupan sehari-hari, menanggapi pertanyaan peserta didik, dan pembuatan rangkuman materi pembelajaran. 3) Hasil observasi penilaian pembelajaran berada pada kategori tidak baik, karena penilaian yang dilakukan oleh guru hanya pada aspek kognitif. Dengan demikian perlu adanya peningkatan pada prinsip-prinsip penilaian dan pelaksanaan penilaian pada aspek afektif dan psikomotor. 4) Respon peserta didik berada pada kategori baik hal ini mengindikasikan bahwa kegiatan pembelajaran yang dikelola oleh guru mendapat respon yang positif dari peserta didik. 5) Hasil belajar peserta didik dapat dikatakan efektif dan berhasil dengan prosentase ketuntasan belajar sebesar 96,00%. LEARNING EFFECTIVENESS OF THE COMPUTER ENGINEERING AND INFORMATICS PRODUCTIVE GROUP APPLYING THE SCHOOL-BASED CURRICULUM IN STATE VOCATIONAL HIGH SCHOOLAbstractThis study aims to describe the learning effectiveness of the productive group in the computer engineering and informatics study program applying the School-Based Curriculum in state vocational high schools (SVHSs) in terms of: 1) the completeness and appropriateness of the learning kits, 2) the learning process, 3) the learning assessment, 4) the students’ responses to the learning activities, and 5) the students’ learning outcomes. This was a survey study with a population comprising two SVHSs in the regency of Hulu Sungai Utara. Based on the results of the analysis, it can be concluded that learning in the computer engineering and informatics productive group applying the School-Based Curriculum has been effective. It can be seen from the following aspects. 1) The results of the review of the completeness and appropriateness of the productive learning kits consisting of syllabuses and lesson plans developed by teachers are in the good category. The formulation and development of the planning kits already refer to the content standards, competency standards and are in accordance with the steps and School-Based Curriculum format. However, the aspect of identifying learning materials, the learning experience formulation, the formulation of competency achievement indicators, and assessment forms need to be improved. 2) The results of observations on the learning process are in the good category. Thus, the learning process is already in conformity with the process standard. However, the aspects of applying the materials from daily life, responding to the students’ questions, and making a learning material summary need to be improved. 3) The results observations on the learning assessment are in the poor category, because the assessment carried out by teachers focuses only on the cognitive aspects. Thus, the principles of assessment and implementation of assessment in the affective and psychomotor aspects need to be improved. 4) The students’ responses are in the good category. This indicates that the learning activities managed by teachers get positive responses from the students. 5) The students’ learning outcomes are relatively effective and successful with a percentage of learning mastery of 96,00%.
