Abstract

This study aims to examine the impact of water distribution service quality on customer complaints as part of efforts to enhance customer satisfaction at Perumda Air Minum Tirta Hita Buleleng. A quantitative approach was employed, with data collected through questionnaires. The questionnaire responses were measured using an interval scale. Respondents were selected using random sampling techniques. The data were analyzed using SmartPLS software. The study explored three main relationships: the influence of water distribution service quality on customer complaints, the influence of water distribution service quality on customer satisfaction, and the influence of customer complaints on customer satisfaction. The findings indicate that all relationships examined are positive and significant, highlighting the critical role of service quality in reducing complaints and improving customer satisfaction.

Abstract

The oxygen mask system on an aircraft is one of the important elements in maintaining the safety of passengers and crew in emergency situations, especially when there is a loss of cabin pressure. This study aims to examine the effectiveness and working mechanism of the oxygen mask system on classic Boeing aircraft, namely the Boeing 737-300, 737-400, and 737-500, during an emergency. The method used in this study is descriptive qualitative, with data collection techniques through interviews, observations, and literature studies. The results of this oxygen mask system study involved various units on the aircraft, including the Passenger Service Unit (PSU), Restroom Service Unit (LSU), and Attendant Service Unit (ASU). Oxygen in the aircraft is supplied from a cylinder through a pressure regulator, and the oxygen mask is automatically released when the cabin pressure drops below a certain threshold. In addition, the oxygen system can also be activated manually by the flight crew. One of the challenges is passenger confusion regarding the correct use of oxygen masks. This study also examines applicable safety regulations as set by the FAA and ICAO, to ensure that the oxygen system functions optimally in an emergency. The study also provides recommendations to improve routine training for cabin crew in handling oxygen mask systems and other safety procedures.
