Abstract

This study aims to determine the effect of organizational culture and organizational commitment on employee performance in tourism 4.0 in Madura. This type of research is a quantitated qualitative research. The data collection technique was by distributing questionnaires using a Likert scale from 1 to 5. The sampling technique used saturated sampling because the population and sample in this study were the same, namely as many as 70 employees working in the tourism industry in Bangkalan Regency. The results of the study show that organizational culture has no significant effect on employee performance variables, because the more conducive organizational culture that is applied to Tourism 4.0 in Madura does not necessarily improve the performance of its employees who tend not to be creative. Then organizational commitment has a significant effect on employee performance, because the desire of employees to continue working in accordance with organizational goals without coercion, reflects a sense of pride in employees so that they do not need to be monitored with a low level of resignation. The advice that can be given is that it is hoped that tourism managers in Madura will always improve the rules that must be considered by their employees. Keywords: Organizational Culture, Organizational Commitment, Performance

Abstract

Limbah cair pabrik kelapa sawit (Palm Oil Mill Effluent/POME) memiliki kandungan bahan organik yang tinggi, yang tercermin dari nilai Chemical Oxygen Demand (COD), sehingga berpotensi menimbulkan pencemaran lingkungan apabila tidak diolah secara memadai. Penelitian ini bertujuan untuk mengevaluasi kemampuan adsorben berbasis limbah ampas kopi dalam menurunkan COD POME serta mengkaji kinetika adsorpsinya. Proses adsorpsi dilakukan secara batch dengan variasi waktu kontak 35–95 menit. Karakterisasi adsorben dilakukan menggunakan Fourier Transform Infrared Spectroscopy (FTIR) untuk mengidentifikasi gugus fungsi dan Scanning Electron Microscopy (SEM) untuk mengamati morfologi permukaan. Analisis kinetika adsorpsi difokuskan pada model Elovich, Bangham, dan Boyd untuk menilai kesesuaian model terhadap data eksperimen. Hasil penelitian menunjukkan bahwa adsorben ampas kopi mampu menurunkan COD POME dengan efisiensi maksimum 13,13% dan kapasitas adsorpsi 2,8604 mg/g pada waktu kontak optimum 65 menit. Di antara model yang diuji, model Bangham memberikan kecocokan terbaik, sedangkan model Boyd menunjukkan kesesuaian yang sangat rendah. Temuan ini menunjukkan bahwa adsorben limbah ampas kopi berpotensi digunakan sebagai adsorben alternatif, tetapi masih memerlukan optimasi lebih lanjut sebelum diterapkan pada skala yang lebih luas.
