ABSTRACTThe COVID-19 pandemic requires teachers to think carefully and creatively in designing learning so that it remains interactive and appropriate to achieve the learning goals. Physics learning with using a flute and a smartphone described in this paper is the result of a thought process about how students can still conduct experiments from home using simple equipment to measure the speed of sound in the air and at the same time learn the concepts of loudness and pitch of sound. A total of 37 eighth grade students in 2020/2021 academic year and 23 students in 2018/2019 acadeymic year at a private junior high school in Bekasi were involved in a pre-experimental study with a one-group posttest only design. A set of 10-item multiple-choice diagnostic tests taken from the Mechanical Wave Conceptual Survey and summative tests in the form of structured questions were arranged to test students' conceptual understanding after receiving sound wave learning. The average of diagnostic test and summative test in the 2018/2019 and 2020/2021 academic years were 30, 48 and 60 respectively out of 100 with a summative test completion percentage of 35% in 2018/2019 and 70% in 2020/2021 . Keywords: physics experiment, sound waves, recorder, smartphoneABSTRAK Masa pandemi Covid-19 menuntut guru untuk terus berpikir secara hati-hati dan kreatif dalam merancang pembelajaran agar tetap interaktif dan tepat mencapai tujuan pembelajaran yang ditetapkan. Pembelajaran dengan menggunakan suling dan berbantuan gawai yang dipaparkan dalam tulisan ini merupakan hasil dari proses berpikir tentang bagaimana siswa tetap dapat melakukan eksperimen dari rumah memanfaatkan peralatan sederhana untuk mengukur kelajuan gelombang bunyi di udara dan sekaligus mempelajari konsep kekerasan bunyi (loudness) dan tinggi nada (pitch) bunyi. Siswa kelas delapan sebanyak 37 siswa tahun ajaran 2020/2021 dan 23 siswa tahun ajaran 2018/2019 pada salah satu sekolah menengah pertama swasta di Kota Bekasi dilibatkan dalam penelitian pre-experiment dengan desain one-group posttest only. Seperangkat tes diagnostik berbentuk pilihan ganda sebanyak 10 butir yang diambil dari Mechanical Wave Conceptual Survey dan tes sumatif berbentuk uraian disusun untuk menguji pemahaman konsep siswa setelah mendapatkan pembelajaran gelombang bunyi. Rata-rata tes diagnostik dan tes sumatif pada tahun ajaran 2018/2019 dan 2020/2021 berturut-turut sebesar 30, 48 dan 60 dari maksimum nilai 100 dengan persentase ketuntasan tes sumatif sebesar 35% di 2018/2019 dan 70% di 2020/2021.Kata kunci: eksperimen fisika, gelombang bunyi, suling, gawai

As a demand of English learning, eighth grade students need to be able to write a recount text about their personal experiences. For this reason, this study employs a qualitative case study research design to analyse students’ writing of recount text. The data were obtained by collecting students’ writing in two different classes of eight grade junior high school in Bandung, Indonesia during the even semester of academic year 2016/2017. The self-composed recount texts were selected based on different proficiency levels as suggested by the English teacher of the school. For the framework of the text analysis, this study draws on Systemic Functional Linguistic theory, and recount text. Meanwhile, content analysis was employed to explore the analysis of the writing. The results presented that majority of problems on the students’ writings consist of social function and language feature. In terms of language features, there were still several errors in spelling, punctuation and capitalization. In term of Interpersonal metafunction, errors usually occurred in the Finite as there was an overlap of past tense and present tense. As a result, it was found that most of the clauses were written in material process and it still lack of reference in the theme-rheme structure.

Having good grammar is one of important components in the mastery of writing skills. However, grammatical errors still become an important problem in writing, especially for EFL students. Therefore, this study aimed to find out the major types of grammatical errors; and to know the major source of grammatical errors in students’ recount text writing. This study was designed as a descriptive qualitative study. Recount texts written by the eighth-grade students of SMP Pelangi Dharma Nusantara in academic year 2019/2020 were used as the research subjects of this study. The data were identified and analyzed using  theory of error proposed by Dulay et al. (1982) about surface strategy taxonomy and theory of source of grammatical error proposed by Brown (2007)). The findings showed that the major type of grammatical errors was omission, with the total of 171 errors or 37. 33% of the total errors. Meanwhile, the major source of grammatical errors was intralingual transfer which the total result was 248 or 43.43% error. Thus, it can be concluded that the most frequent grammatical errors that happened among the subject was error of omission, while the most common source of errors was intralingual transfer.

Mathematics is often considered a scourge for the field of study that is considered difficult and boring, the learning carried out is teacher-centered where students are less active and only accept the learning delivered by the teacher. Based on this background, the purpose of this research is to find out the improvement of students' mathematical understanding skills whose learning uses Skinner's learning theory through picture and picture models, to find out the differences in students' mathematical understanding abilities who use Skinner's learning theory through picture and picture models with those who do not use Skinner's learning theory but through the picture and picture model, and knowing the student's response to learning using Skinner's learning theory through the picture and picture model. The research method used is a true experimental method with a population of all eighth-grade students of Ibnu Hajar Mandiri Bekasi Junior High School for the 2020/2021 academic year. Sampling was done purposively. The instrument is a test about the description of students' mathematical understanding abilities on function material and questionnaire sheets. The results showed that learning mathematics using Skinner's learning theory through picture and picture models can improve students' mathematical understanding skills, besides that there are differences in the mathematical understanding of students whose learning uses Skinner's learning theory through picture and picture models with students whose learning does not use Skinner's learning theory but through picture and picture models. The student's response after using Skinner's learning theory through the picture and picture model was considered good. This shows that only a small number of students still consider mathematics a very difficult and boring subject.

This research was conducted by using a descriptive method with a quantitative approach. The quantitative approach was chosen to be tested theories by examining and measuring variables in the form of relationships, differences, influences, contributions, and the others. The research was carried out by describing the students acquisition data on the new student admission (PPDB) using zoning system based on the academic year 2019-2020 and the student acquisition data on the academic year PPDB 2018-2019 as a comparison. Based on the results of the study, the new students of PPDB using zoning system was considered lower in terms of economic and educational background of parents. There were more parents with less education (elementary & junior high school) in the zoning system than in the rayon system, whereas parents with higher education in the zoning system were fewer than the rayon system.  Likewise, in terms of income, there were more people with the low income in the zoning system than in the rayon system, and those having high income were fewer than in the rayon system. The study showed that the intelligence and the result of National Examination Score (NUN) in the zoning system is lower than in the rayon system. The intelligent level of the students in the zoning system is mostly dominated by the scores under 90-109, while in the rayon system were dominated by the scores above 90-109.  The National Examination Scores (NUN) in the zoning system were evenly distributed from a range of scores 0 to 30, while in the rayon system the scores were dominated by a range of scores 28-30, with the lowest score 24.
