Abstract

Semakin maju dan berkembangnya ilmu pengetahuan dan teknologi di bidang mechanical engineering khususnya di bidang tribologi, maka akan semakin banyak terungkap faktor-faktor yang dapat mempengaruhi umur pemakaian  komponen dari sebuah mesin. Besi cor adalah salah satu bahan untuk membuat komponen dari suatu mesin. Penelitian kali ini menggunakan tribometer pin-on-disc dengan besi cor A (79.5 HRB), besi cor B (82 HRB) dan besi cor A (86.5 HRB) sebagai disc dan bola baja AISI 52100 berdiameter 8,0 mm dengan kekerasan 60 HRC sebagai pin. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan material disc dan ukuran diameter pin terhadap nilai lebar kontak keausan, koefisien keausan berdimensi, volume dan tinggi keausan yang terjadi pada besi cor. Kajian juga membandingkan hasil keausan dengan berbagai model yang yang telah ada sebelumnya. Analisa perhitungan menggunakan penurunan geometri berdasarkan rumus matematika dasar sederhana dan menggunakan metode penurunan persamaan Archard. Hasil penelitian menunjukkan bahwa lebar kontak keausan, koefisien keausan berdimensi (KD), ketinggian keausan (h) dan volume keausan (V) mempunyai hubungan berbalik nilai dengan kekerasan material dan senilai dengan jarak sliding (s). Ukuran diameter pin mempunyai hubungan sebanding dengan lebar kontak aus, koefisien keausan berdimensi (KD), ketinggian keausan (h) dan volume keausan (V). Semakin keras suatu material maka keausan yang terjadi akan semakin kecil.Kata kunci: keausan, besi cor, pin-on-disc, Archard, metode sederhana

Abstract

The aim of this research is to obtain opportunities for Islamic boarding school innovation from Law Number 18 of 2019. The research method uses qualitative methods, namely examining the text of the law, educational innovation books and relevant journals. The research results obtained are (1) Innovation opportunities for Islamic boarding school institutional units. In accordance with article 5 paragraphs 1a, 1b and 1c. There are the Buku Kuning Islamic boarding schools, Dirasah Islamiah or Muallimin Islamic boarding schools and other forms of Islamic boarding schools that are integrated with General Education. (2) Opportunities for innovation in combining Islamic boarding schools with universities from article 22 paragraph 1 and paragraph 7. Islamic boarding schools are combined with universities or Islamic boarding school-based colleges. (3) Opportunities for innovation in combining Islamic boarding schools with vocational training centers. The basis is article 19 paragraph 2b, article 21 paragraph 2b and article 23 paragraph 4. At a minimum, Islamic boarding school graduates must have work skills to be accepted for work. (4) Opportunities for establishing a community service division which has been mandated in article 45. (5) Opportunities for establishing a masayikh council tasked with ensuring the quality of Islamic boarding schools. This task is regulated in article 27 paragraphs 1, 2, 3a, 3b, 3c, 3d and 3e. (6) The opportunity for institutions to receive financial assistance from the government is greater as explained in articles 48 and 49.
