Abstract

The result of a turning process is strongly influenced by the process parameters that could result in the product to be unacceptable. The cutting parameters may be determined according to the material hardness and roughness of the workpiece surface. The purpose of this paper is to investigate the effects of cutting speed and feed rate on surface roughness and vibration. In Taguchi method, the number of experiments is reduced by orthogonal arrays while  the effects of uncontrollable factors are also also reduced. The Taguchi method is used to reduce track, experimental time and production cost. Simple and precise are the most benefits of this method. Unstable vibrations in machining operations, known as chats, can cause damage to tools, workpieces, and machine tools. Cutting force is found to be the most dominant factor affecting surface roughness.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh e-service quality terhadap e-customer loyalty pada aplikasi e-banking Bank Syariah Indonesia (BSI). Penelitian ini menggunakan metode penelitian kuantitatif dengan mengumpulkan data melalui kuesioner dari pengguna aktif aplikasi e-banking BSI. Pengolahan dan analisis data menggunakan regresi linear sederhana melalui SPSS 24. Sampel dalam penelitian ini berjumlah 80 responden yang dilakukan dengan teknik insidental sampling. Variabel utama yang diukur melibatkan indikator e-service quality yaitu efficiency, fulfillment, system availability, privacy, responsiveness, compensation dan contact.  Hasil dari penelitian ini menunjukkan bahwa e-service quality berpengaruh secara signifikan terhadap e-customer loyalty pada aplikasi e-banking Bank Syariah Indonesia (BSI). Temuan ini dapat memberikan panduan bagi BSI untuk meningkatkan aspek-aspek tertentu dalam e-service quality mereka guna memperkuat ikatan dengan nasabah. Implikasi praktis dari penelitian ini adalah memberikan kontribusi pada pengembangan pengelolaan layanan elektronik dalam industri perbankan syariah.
