Abstract

Penelitian ini dilakukan dengan metode eksperimental yang bertujuan untuk mengetahui pengaruh fraksi serat dengan variasi perendaman air laut terhadap kekuatan tarik komposit berbahan dasar serat sabut kelapa dan resin epoxy. Spesimen dibentuk sesuai standar uji tarik ASTM D3039 kemudian diuji tarik menggunakan mesin uji tarik merek Autograph Shimadzu dengan tipe Universal Testing Machine. Dengan fraksi volume yang digunakan dalam penelitian ini yaitu fraksi volume 50% serat : 50% resin dengan perendaman air laut 14 hari. Hasil penelitian kekuatan tarik pada material komposit berbahan dasar serat kelapa dengan  rata-rata tegangan tarik sebesar 11,13 MPa dan regangan tarik sebesar 1,06 tanpa perendaman air laut, dan  rata-rata tegangan tarik sebesar 19,66 MPa, dan regangan tarik 1,61 dengan perendaman air laut.

Abstract

Kesiapan fisik remaja SMK berperan penting dalam mendukung kemampuan siswa melaksanakan tugas praktik secara aman, efisien, dan produktif. Aspek fisik tersebut meliputi kekuatan otot, fleksibilitas, daya tahan kardiovaskular, serta kondisi kesehatan seperti status gizi dan indeks massa tubuh. Faktor-faktor seperti pola makan, aktivitas fisik, stres, kualitas tidur, fasilitas olahraga, serta dukungan keluarga dan sekolah turut memengaruhi tingkat kebugaran siswa, sedangkan pola hidup sedentari dapat meningkatkan risiko cedera. Penelitian ini menggunakan metode studi literatur dengan menelaah jurnal, buku, dan laporan ilmiah terkait kebugaran remaja dan kebutuhan fisik pendidikan vokasi. Hambatan kesiapan fisik juga muncul dari belum optimalnya pembinaan fisik di sekolah serta kurangnya keselarasan dengan tuntutan industri. Oleh karena itu, peningkatan kesiapan fisik perlu dilakukan melalui latihan terstruktur, edukasi gizi, pemeriksaan kesehatan berkala, dan penerapan budaya hidup sehat. Siswa dengan kesiapan fisik baik memiliki produktivitas lebih tinggi dan risiko cedera lebih rendah.

Abstract

This study aims to map the scientific publication landscape on character education from an Islamic perspective using a Google Scholar–based bibliometric approach. Data were collected through Publish or Perish using the query (“character education” OR “moral education”) AND Islam for the 2015–2025 publication period, exported in RIS format, and analyzed in VOSviewer to generate keyword co-occurrence maps. The dataset consists of 500 documents with 18,309 total citations, averaging 1,664.45 citations per year and 36.62 citations per document. Citation impact indicators show an h-index of 62 and a g-index of 103, and most documents have received at least one citation (488 documents with ≥1 citation). VOSviewer visualizations position “character education” as the most dominant and central node, closely connected to conceptual and implementation-related themes such as “moral education,” “concept,” “school,” “Islamic boarding school/Islamic boarding school,” “management,” “character education program,” “family,” and “child,” while “digital era” emerges as a peripheral contemporary context. Overall, the mapping indicates that research on Islamic character education forms a thematic structure linking conceptual–normative foundations with institutional and programmatic dimensions of implementation. This study contributes a thematic roadmap that can inform more focused future research, particularly by strengthening connections across clusters and exploring still-peripheral topics.
