Full text linkThe objective of this research is to analyze the impact of profitability, leverage, and firm size toward tax avoidance in coal companies listed on the Indonesia Stock Exchange for the period of 2020 to 2022. The independent variables used in this research are profitability measured by Return on Assets Ratio (RoA), leverage measured by Debt-to-Equity Ratio (DER) and firm size measured by total assets. Meanwhile, the dependent variable in this research is tax avoidance measured by Effective Tax Rate (ETR).
The population in this research is coal companies listed on the Indonesia Stock Exchange for the period of 2020 to 2022, in which the samples are determined by using the Purposive Sampling Method, resulting in 11 companies selected with a total of 33 samples. The data analysis method used descriptive statistics, classical assumption tests, multiple linear regression, and hypothesis tests, which are processed utilizing SPSS 26.
The research result shows that profitability and leverage partially do not have significant impact toward tax avoidance. Meanwhile, firm size partially has a significant impact toward tax avoidance. Moreover, profitability, leverage, and firm size simultaneously have a significant impact toward tax avoidance
Reaksi Pasar terhadap Capaian Kinerja Perusahaan pada Perusahaan dengan Kualitas Audit yang Berbeda
Full text linkTujuan dari penelitian ini adalah untuk menguji pengaruh capaian kinerja perusahaan terhadap reaksi pasar modal. Penelitian ini juga menguji apakah pengaruh capaian kinerja keuangan perusahaan terhadap reaksi pasar modal tersebut akan berbeda pada perusahaan-perusahaan dengan tingkatan kualitas audit yang berbeda. Dalam pengujian hipotesis, penelitian ini menggunakan pemodelan Earnings Response Coefficient (ERC) untuk meregresikan CAR (cumulative abnormal returns) terhadap kinerja keuangan perusahaan (profitabilitas, likuiditas dan solvabilitas), AQ (audit quality) dan interaksi antara kinerja keuangan perusahaan dan AQ (audit quality), dengan menggunakan data tahun 2016-2018 untuk 60 perusahaan sampel yang terdaftar pada Bursa Efek Indonesia (169 firm-year). Hasil pengujian menunjukkan bahwa pada sampel perusahaan yang dipilih solvabilitas berpengaruh negatif signifikan pada reaksi pasar dan kualitas audit secara signifikan memperlemah hubungan negatif antara solvabilitas dengan reaksi pasar tersebut. Sementara itu, penelitian ini tidak memberikan bukti empris mengenai pengaruh likuiditas dan profitabilitas terhadap reaksi pasar dan pengaruh kualitas audit terhadap hubungan profitabilitas dengan reaksi pasar dan likuiditas dengan reaksi pasar. Dengan demikian, penelitian ini hanya memberikan sebagian bukti empiris pengaruh kinerja perusahaan terhadap reaksi pasar dan pengaruh moderasi kualitas audit dalam hubungan keduanya
THE GROUPING METHOD AS A PEDAGOGICAL STRATEGY TO ENHANCE JUNIOR HIGH SCHOOL STUDENTS' PROFICIENCY IN CONSTRUCTING SIMPLE PRESENT TENSE SENTENCES [METODE PENGELOMPOKKAN SEBAGAI STRATEGI PEDAGOGIS UNTUK MENINGKATKAN KEMAMPUAN SISWA SMP DALAM MENYUSUN KALIMAT SINGKAT DALAM BENTUK PRESENT TENSE]
Full text linkThe simple present tense is a fundamental grammar structure in English as a Foreign Language (EFL) learning, yet it remains a source of difficulty for many junior high school students, particularly in relation to subject-verb agreement and sentence construction. This study investigates the effectiveness of the grouping method as a pedagogical strategy to improve students' proficiency in constructing simple present tense sentences. A mixed-methods research design was employed with 60 Grade 7 students from a junior high school in Indonesia. The intervention involved implementing the grouping method in three phases: teaching verbal sentences (Group A: plural/subjects other than third-person singular; Group B: third-person singular), teaching nominal sentences (Group C: to be constructions), and integrating both types of sentences. Data were collected through pre- and post-tests, classroom observations, student questionnaires, and semi-structured interviews. Results indicated a significant improvement in students' accuracy in constructing simple present tense sentences, a reduction in cognitive load, and an increase in motivation and confidence. The findings suggest that the grouping method is a valuable strategy for EFL teachers to enhance students' grammar proficiency and engagement.

Parallel Editing in Conveying Parental Acceptance in the Short Film Manusia Bebas (2025)
No full textDalam dunia sinema modern, penyuntingan tetap memegang peran penting untuk mendukung struktur naratif dan menguatkan emosi yang dirasakan oleh penonton. Salah satu cara yang efektif untuk menyampaikan dua kejadian atau lebih yang saling berhubungan ialah parallel editing atau penyuntingan paralel. Strategi penyuntingan ini memungkinkan penyajian dua peristiwa yang berlangsung di tempat berbeda secara bersamaan, sehingga menciptakan kesinambungan emosional dan tematik yang kuat. Manusia bebas adalah film pendek yang mengisahkan tentang konflik keluarga antara anak yang mencintai musik dan ayah yang tidak mendukung pilihannya. Fokus penelitian ini terletak pada klimaks yang menggambarkan adegan penerimaan orang tua (parental acceptance) terhadap keputusan anaknya tetap berkarir di dunia musik. Penyuntingan paralel dimanfaatkan untuk membangun koneksi emosional antara ayah dan anak meski tidak berada dalam ruang yang sama. Metode yang digunakan dalam penelitian ini adalah kualitatif dengan pendekatan studi kasus film pendek Manusia Bebas. Prosesnya dimulai dari studi literatur, menyortir footage-footage film dan pengujian langsung melalui praktik penyuntingan paralel pada footage tersebut. Data dikumpulkan melalui kumpulan footage dari hasil produksi film. Hasil penelitian menunjukkan bahwa penyuntingan paralel yang dikombinasikan dengan transisi visual mampu membangun hubungan emosional antara dua karakter dari ruang yang berbeda, tanpa harus menggunakan dialog verbal. Temuan ini membuktikan bahwa penyuntingan paralel dapat berfungsi sebagai perangkat naratif, khususnya hubungan keluarga dalam sinema. Proses penyuntingan tidak hanya menghasilkan koneksi visual tetapi memberikan pengalaman emosional yang kompleks pada penonton. Dengan membandingkan film-film dengan penyuntingan parallel, penelitian ini juga mengevaluasi efektivitas visual dalam membangun makna dan ketegangan emosi secara bertahap.

Repetisi Simbol Lingkaran Pada Pembuka Ke 25 Anime One Piece
Full text linkOne Piece merupakan mahakarya komikus Jepang, Eichiiro Oda, yang telah meraih kesuksesan global sejak awal perilisannya pada tahun 1997. Kejeniusan Oda dalam meramu jalan cerita merupakan kunci sukses dari serial One Piece sehingga masih berlangsung hingga kini. Serial anime One Piece telah bekerjasama dengan banyak musisi yang menyumbangkan lagu untuk pembukaan dan penutupnya. Pada episode 1074, pembuka anime One Piece menggunakan lagu "Saiko Totatsuten" (yang berarti “Titik Tertinggi”) karya band Jepang "Sekai No Owari". Pembuka ke-25 ini terasa spesial karena menjadi pengantar menuju akhir petualangan kru bajak laut Topi Jerami di Negeri Wano (negeri para samurai). Peneliti mengangkat topik ini karena dalam pembuka anime tersebut menyisipkan banyak simbol lingkaran yang muncul dari awal hingga akhir. Lingkaran atau dalam budaya Jepang disebut “Enso”, dijelaskan sebagai simbol integritas, ketidakterbatasan, dan keabadian yang merepresentasikan dewa matahari. Berdasarkan teori Image of Time, lingkaran mencerminkan perjalanan waktu dan peristiwa-peristiwa kronologis. Landasan teori inilah yang membagi pembahasan artikel ini ke dalam tiga bagian utama yaitu sejarah dan penjajahan negeri Wano, perjuangan pembebasan negeri Wano, hingga perayaan kemenangan perjuangan di negeri Wano. Hasil kajiannya bahwa pembuka ke 25 anime One Piece memuat banyak nilai mitos primitif, seputar hidup-mati, manusia-dewa/dewi, serta baik-jahat/buruk. Maka demikian, sebegitu menariknya simbol-simbol lingkaran dalam pembuka anime ke-25 One Piece untuk dikaji, karena kandungan makna-makna simbolik yang tersembunyi di baliknya
Evaluating the Effectiveness and Safety of a Shortened Rifapentine-Moxifloxacin Regimen in Treating Drug-Sensitive Pulmonary Tuberculosis: A Systematic Review
Full text linkBackground:
Prolonged treatment duration remains a key challenge in managing drug-sensitive pulmonary tuberculosis (DS-TB), contributing to poor adherence and treatment failure. Recent evidence suggests that regimens incorporating rifapentine and moxifloxacin (RPT+MOX) may allow for effective 4-month treatment courses.
Methods:
We conducted a systematic review and meta-analysis following PRISMA 2020 guidelines to evaluate the effectiveness and safety of shortened RPT+MOX regimens. PubMed, EMBASE, and Scopus were searched up to May 2025. Eligible studies included randomized trials or observational cohorts comparing shortened RPT+MOX regimens with standard 6-month therapies in patients with DS-TB. Outcomes included culture conversion at 8 weeks, relapse or treatment failure, and serious adverse events. Risk of bias was assessed using the ROBINS-I tool.
Result:
Five studies (three RCTs, two observational) met inclusion criteria. Pooled analysis showed no significant difference in risk for relapse or treatment failure (RR 0.79, 95% CI: 0.37–1.67), culture conversion (RR 1.16, 95% CI: 0.80–1.69), or serious adverse events (RR 0.92, 95% CI: 0.65–1.29) between RPT+MOX and standard regimens. Risk of bias ranged from minimal to moderate. The GRADE assessment supported high certainty of evidence.
Conclusions:
Shortened RPT+MOX regimens demonstrate comparable effectiveness and safety to standard 6-month treatment for DS-TB, supporting their use in appropriate settings. Further studies are warranted to assess long-term outcomes, real-world adherence, and feasibility across diverse populations
Incidence and Risk Factors of Hernia Mesh-Related Infections: A Systematic Review and Meta-Analysis
Full text linkBackground: Prosthetic mesh lowers hernia‑recurrence rates but can precipitate infection; reported incidence and risk factors remain inconsistent. The objective of this systematic review and meta-analysis is to estimate the pooled incidence of hernia mesh infections and to identify the key risk factors associated with their development.Methods: A PRISMA 2020 search of PubMed, EMBASE and Scopus identified randomised, cohort and case‑control studies that reported mesh‑related infection incidence or risk factors ≥ 3 months after adult hernia repair. Two reviewers independently screened records, appraised bias (ROBINS‑I) and graded certainty (GRADE). Random‑effects meta‑analyses generated pooled proportions and risk ratio (RR).Result: Seven studies encompassing 57,653 repairs qualified. Infection incidence ranged 1.3 – 10.2 %; the pooled proportion was 4.9 % (95 % CI 2.6 – 7.4, I² = 87 %). Diabetes (RR 1.49, 95 % CI 1.13 – 1.97) and smoking (RR 1.43, 95 % CI 1.34 – 1.52) were consistent patient‑level risks, whereas obesity (RR 1.48, 95 % CI 0.68 – 3.22) and female sex (RR 1.08, 95 % CI 1.04 – 1.11) exerted smaller effects. Operative time > 2 h, emergency repair, large/PTFE or composite intraperitoneal meshes, and repeat surgery each roughly doubled infection odds. Certainty was low‑to‑moderate overall but high for diabetes and smoking; no publication bias was detected.Conclusions: Roughly one in twenty mesh repairs is complicated by infection. Optimising glycaemic control, enforcing smoking cessation, shortening operations and selecting macroporous meshes may meaningfully lower risk
