Abstract

Practical learning activities on heavy equipment units are important because they increase understanding of work systems and provide an actual picture. The need for excavators for practicum activities in vocational education is currently hampered by price issues when commercial units are used as learning tools, therefore learning media in a more concise form are needed without ignoring important aspects. The manufacture of mini excavator props has been carried out but research related to work system testing is still rare, so performance testing of the work system is needed to ensure the performance of the props. The aim of this research is to test cylinder speed, cylinder pressure and cylinder drift using quantitative observation methods with variations in zero capacity, struck capacity and heaped capacity transport. From the test results, it was found that the cylinder speed values ​​were between 0.028–0.081 m/sec, the cylinder pressure was 17–20 bar for the boom, 65–72 bar for the arm, 24–34 bar for the bucket and the increase in length in the cylinder drift test was 0 mm

Abstract

Perkembangan teknologi informasi telah mendorong instansi pemerintah, termasuk Kantor Urusan Agama (KUA), untuk mengadopsi sistem digital dalam proses administrasinya. Salah satu proses yang memerlukan digitalisasi adalah pengarsipan buku nikah yang sebelumnya masih dilakukan secara manual, sehingga menimbulkan risiko kehilangan data, kesalahan pencatatan, dan lambatnya proses pencarian arsip. Oleh karena itu, penelitian ini bertujuan untuk merancang dan membangun sistem informasi pengarsipan buku nikah berbasis web yang dapat membantu admin KUA dalam mengelola data secara lebih efektif dan efisien. Sistem ini dibangun menggunakan metode pengembangan sistem waterfall, dengan pendekatan perancangan menggunakan Unified Modeling Language (UML) seperti use case diagram dan activity diagram. Fitur utama dalam sistem ini meliputi login sistem, input data buku nikah, pencarian data, pengeditan data, serta pencetakan laporan arsip. Hasil dari perancangan ini menunjukkan bahwa sistem mampu mempermudah proses pengarsipan, mempercepat pencarian data, serta meningkatkan akurasi dan keamanan data arsip buku nikah.
