Reduksi gerakan rolling pada kapal dapat meningkatkan keamanan operasional kapal. Stabilizer pada kapal dapat didefinisikan sebagai suatu alat untuk mereduksi gerakan rolling daripada kapal saat berada di atas laut berombak. Performa stabilizer eksternal dinilai kurang baik saat kecepatan rendah jika dibandingkan dengan stabilizer internal. Disamping itu potensi bahaya yang ditimbulkan oleh penambahan stabilzer eksternal kemungkinan juga akan lebih besar dikarenakan diperlukan penambahan dimensi untuk instalasinya. Internal stabilizer system seperti gyro stabilizer tidak mempengaruhi penambahan dimensi keseluruhan kapal dikarenakan pemasangan bersifat built-in, serta tidak memerlukan dry docking pada saat pemeliharaan berlangsung. Objektif dari penelitian ini adalah untukmerancang bangun penggunaan gyro stabilizer pada sebuah replika hull kapal dan menganalisanya dengan metode pengujian Decay Roll Test. Dengan memberikan variasi kecepatan putar dari flywheel pada mekanisme gyro stabilizer sebesar 0 RPM, 5000 RPM, 10000 RPM, dan 15000 RPM, terhadap simpangan rolling dari kapal. Proses perekaman grafik rolling dilakukan dengan rotational sensor pada perangkat berbasis sistem operasi android.Hasil pembacaan grafik roll time trace didapatkan periode rolling bertambah panjang seiring dengan penambahan kecepatan putar flywheel, dengan periode terpanjang T? = 1.4858 detik pada putaran 15000 RPM. Sementara dengan metode Froude dan Bertin, didapatkan kenaikan nilai koefisien roll damping tertinggi 62% pada kecepatan putar flywheel 10000 RPM dari kondisi flywheel 0 RPM (Kondisi gyro off). Kata Kunci: Gyro stabilizer, kecepatan putar flywheel, pergerakan rolling, periode, roll damping, decay roll test.

This current research aims to investigate the beliefs and rationales of EFL university teachers about giving or not giving written feedback to their students. The researchers employed a descriptive qualitative approach in the execution of this study. Three experienced EFL university teachers agreed to participate in in-depth interviews to gain the data. This research revealed five distinct beliefs regarding providing written feedback. They hold beliefs about giving feedback based on the importance of giving feedback, the role of giving feedback to other types of feedback, the length of feedback, students' competence-based in giving feedback, and the importance of giving balanced feedback. As for their rationales for giving and not-giving feedback, several findings were documented. They provided written feedback because it gave some crucial information by showing students' identifiable learning records and enhancing their academic output. Also, it holds relevance to the teachers’ teaching profession. On the other hand, their rationale for not-giving written feedback could be noticed as written feedback, to some extent, demotivated students and took much more time to provide feedback. In the end, teachers' pedagogical implications are also presented by recalling the findings of this current research.

This research aims to determine the spiritual intelligence and environmental literacy of SMP Negeri 1 Bojongasih class IX students. Respondents in this study consisted of 76 class IX students. The research method used is descriptive quantitative. The instrument used to measure spiritual intelligence is a Likert scale from 1-4 questionnaire, and to measure environmental literacy using a multiple choice test. The spiritual intelligence indicator refers to research by Fatima (2022), which consists of 9 indicators, while the ecological literacy indicator relates to research by Liang et al. (2018), which consists of three main elements, namely: cognitive (knowledge and skills), affective, and behavioural (behaviour). The multiple choice test only measures the mental aspects of students' environmental literacy. The collected data will be analysed manually using descriptive statistics to determine students' test results by dividing the score obtained by the respondent by the maximum score multiplied by 100. The research results show that the students' spiritual intelligence is reasonable, with scores ranging from 68,20-82,68, which indicates a pretty good foundation for spiritual intelligence, although they still need further guidance. Meanwhile, the environmental literacy test results on the cognitive obtained the highest average value of 44.44 with sufficient criteria. These findings indicate differences in understanding of environmental literacy among students, which need to be improved through more effective learning strategies. Abstrak.

This study was conducted in public junior high schools spread across West Java which are quality schools in the district/city, which amounted to 21 schools In this study the author used "Effective Schools, School-Based Quality Improvement Management," as the grand theory. This study is intended to explain the effectiveness of the relationship between the vision, mission and quality of school performance. This study uses quantitative methods with descriptive statistical research models because the sample used is a saturated sample model because the population is less than 30. Data were obtained by distributing valid and reliable instruments to each school, with 8 (eight) respondents per school consisting of: principals and vice principals, Mathematics, Science and English teachers and school committees. In this study, the independent variable is the vision and mission of the school while the quality of school performance is the dependent variable. In this study the authors found that: Correlation of vision, school mission based on the results of the analysis showed a moderate/sufficient relationship to the quality of school performance, but did not affect the quality of school performance, this means that the vision and mission of the school did not make an important contribution to the school in improving the quality of its performance. ABSTRAKPenelitian ini dilakukan di SMP Negeri yang tersebar di wilayah Jawa Barat yang merupakan sekolah bermutu di kabupaten/ kota, yang jumlahnya 21 sekolah Dalam penelitian ini penulis menggunakan ”Sekolah Efektif, Manajemen Peningkatan Mutu Berbasis Sekolah,” sebagai grand theory. Studi ini dimaksudkan untuk menjelaskan efektifitas hubungan antara visi, misi sekolah terhadap mutu kinerja sekolah. Penelitian ini menggunakan metode kuantitatif dengan model penelitian statistik deskriptif karena sampel yang digunakan adalah model sampel jenuh karena jumlah populasinya kurang dari 30. Data diperoleh dengan cara menyebarkan instrument yang valid dan reliabel kepada tiap sekolah, dengan responden tiap sekolahnya 8 (delapan) orang yang terdiri dari : kepala sekolah dan wakil kepala sekolah, Guru Matematika, IPA dan Guru Bahasa Inggris serta Komite sekolah. Dalam penelitian ini yang menjadi variabel bebas adalah visi, misi sekolah sedangkan mutu kinerja sekolah sebagai variabel terikat. Dalam penelitian ini penulis menemukan hasil bahwa: Korelasi visi, misi sekolah berdasarkan hasil analisis menunjukkan adanya hubungan sedang/cukup terhadap mutu kinerja sekolah, tetapi tidak mempengeruhi mutu kinerja sekolah, hal ini berarti visi dan misi sekolah sekolah tidak memberikan kontribusi penting kepada sekolah dalam meningkatkan mutu kinerjanya.

This article examines the role of pentahelix collaboration in promoting human resource development (HRD) for micro, small, and medium enterprises (MSMEs) using a bibliometric approach. Using 180 Scopus-indexed publications from 2016 to 2025, data were processed with VOSviewer to examine publication trends, co-authorship networks, keyword clustering, and thematic development. The findings indicate that Indonesia contributes the largest number of studies, reflecting its central role in the pentahelix-based development discourse. Five thematic clusters were identified, covering institutional collaboration, digitalization, education, cultural values, village empowerment, and collaborative governance. The results show a gradual shift from conceptual discussions to practical applications, particularly in digital transformation and inclusive governance for MSMEs. Emerging themes such as sustainability, women’s empowerment, and ecosystem-based innovation are gaining significant attention. This study contributes theoretically by refining the conceptual framework of pentahelix collaboration in relation to HRD, while practically providing direction for policymakers, educators, and practitioners to strengthen MSME competitiveness through inclusive and adaptive strategies. By mapping the research landscape, this study highlights the importance of multi-stakeholder collaboration as a foundation for building resilient and innovation-driven MSME ecosystems.
