Abstract

The aim of this research is a comparative analysis of educational resource management models. Educational resource management Refers to the context and factors that influence how educational resources are managed and utilized to achieve set educational goals. In its application, the educational resource model involves evaluating and comparing various approaches, methods or strategies in management, development and utilization of resources to achieve educational goals. The education system in Indonesia has formal, non-formal and informal education systems, and existing educational support must be able to provide adequate educational resources. In writing this article, the library study or library research approach is used, where the researcher collects research-related materials from books, magazines, scientific works, literature, mass media reports, etc., then describes and explains the data.

Abstract

This article aims to describe the philosophical meaning of the traditional weddings of the Singkil Tribe based on data from Lae Butar Village, Gunung Meriah District, Aceh Singkil Regency. This research uses descriptive methods with data collection techniques, namely observation, interviews, and documentation. In the process of presenting data, researchers use data analysis techniques that describe, interpret and validate. The results of the research show that wedding customs are still implemented and maintained by the people in Lae Butar Village to this day. Meanwhile, the traditional wedding procession of the Singkil Tribe in Lae Butar Village is, first, mekhisik, tandek sintua, mebagah, khapat famili, umba-umba and gaba-gaba. The second day, namely, marriage contract, mangan mido tawar, slaughtering animals, religious lectures, hine tetuhu. The third day involve dalalel khairat, tepung tawakh, and hine menangko. On the last day is mangan mekhadat, temetok and pengakhak Mangan mido tawar has a philosophical meaning, which means that those holding a wedding will receive blessings and avoid undesirable things. Tepung tawar means, so that the bride and groom get blessings from the procession. The Singkil Tribe wedding procession in Lae Butar Village combines marriage and custom directly on the same day.

Abstract

This study was conducted to determine the Human Relations Strategy in Realizing Zero Accident (Case Study on HRD PT. Grand Pintalan Textile) by analyzing the strategy using the POAC strategy (Planning, Organizing, Actuating, Controlling). The research uses organizational control theory. The selection of informants was done by the purposive sampling method. Research data was obtained by data collection techniques with in-depth interviews, participant observation, and documentation. This research uses the post-positivism paradigm, a qualitative approach with a case study method. The big concept used is the POAC management concept from G.R Terry. The results of this study show that the HRD Strategy of PT. Grand Pintalan Textile to achieve zero accidents is carried out with four strategies consisting of simple, technical, bureaucratic, and conservative supervision. Besides that, PT. Grand Pintalan Textile implements the POAC strategy through the Human Relations Department. This POAC strategy can be seen from the activities carried out by the Human Relations Department which include knowledge of what to do (planning), determining how to do it (organizing), understanding how they should do it (actuating), and measuring the effectiveness of the efforts that have been made. (controlling).

Abstract

Kavitasi merupakan peristiwa pengikisan permukaan benda dalam hal ini permukaan struktur pelimpah yang terjadi karena perubahan kecepatan mendadak pada saat fluida melewati suatu geometri tertentu. Pelimpah Ogee dan Pelimpah Bulat memiliki bentuk geometri yang berbeda sehingga risiko kavitasi yang terjadi juga pasti berbeda. Data geometri pelimpah yang diambil dalam penelitian ini sebanyak 2 (dua) buah model untuk masing-masing Pelimpah Ogee dan Pelimpah Bulat yaitu rasio P/Hd=3 (tinggi muka air desain 3 m dengan tinggi pelimpah 6 m) hulu vertikal dan hulu miring 1:3. Analisis tekanan dan kecepatan aliran dilakukan dengan Computatonal Fluid Dynamics (CFD) untuk memodelkan perilaku aliran pada suatu geometri struktur dengan metode numerik dalam penelitian ini menggunakan software flow 3D Penilaian risiko kavitasi dengan menghitung Indeks Kavitasi yang terjadi dengan parameter tekanan dan kecepatan aliran yang terjadi pada geometri pelimpah.  Hasil analisis risiko kavitasi menunjukkan pada bagian mercu, pelimpah ogee memiliki risiko lebih rendah dibandingkan dengan pelimpah bulat, sedangkan pada bagian downstream, pelimpah ogee dan pelimpah mempunyai potensi kavitasi yang sama. Secara keseluruhan berdasarkan indeks kavitasi, pada pelimpah P/Hd=3 pelimpah ogee dan pelimpah bulat dengan rasio P/Hd=3 memiliki tingkat risiko yang rendah (aman terhadap kavitasi) sehingga tidak memerlukan penanganan lebih lanjut.

Abstract

Energi fosil memiliki jumlah yang terbatas dan tidak dapat diperbarui. Oleh karena itu diperlukan sumber energi terbarukan agar tidak tergantung dengan sumber energi fosil. Penelitian ini bertujuan untuk mengevaluasi pengaruh jenis dan persentase bahan perekat yang digunakan terhadap nilai kuat tekan dan durabilitas briket kulit durian.  Bahan utama yang digunakan dalam pembuatan briket adalah kulit durian. Bahan perekat yang digunakan adalah daun belimbing wuluh dengan persentase 0%, 2%, 4%, 6%, 8%, dan 10%. Pada penelitian ini dilakukan uji karakterisasi terhadap briket yang dihasilkan dengan acuan ISO 17225-1 dan ASAE S 269.4. Hasil penelitian menunjukkan bahwa nilai kuat tekan terbaik dengan konsentrasi perekat 0% (8,51kg/cm2) dan nilai durabilitas terbaik dengan konsentrasi perekat 8% (92,7%). Berdasarkan hasil pengujian diketahui bahwa penambahan bahan perekat menyebabkan nilai kuat tekan dan nilai durabilitas cenderung menurun.
