Service quality can be interpreted as an effort to fulfill the needs and desires of consumers and the accuracy of delivery in balancing consumer expectations. Service quality can be identified by comparing consumer perceptions of the services they receive with the services expected of the service attributes of a company. If the service received or perceived is as expected, then the service quality is perceived as good and satisfactory. Conversely, if the service received is lower than expected, then the service quality is perceived as bad. In this study, an analysis of customer satisfaction was carried out using the Customer Satisfaction Index (CSI) method at PT. XYZ to determine the level of consumer satisfaction. The results of this study are the customer satisfaction index of 73.228% which describes the customers of PT. XYZ is satisfied with the container depot service. However, improvements still need to be made so that the customer satisfaction index can approach 100% to achieve customer loyalty. To find out what attributes need to be improved an Importance Performance Analysis (IPA) analysis is carried out which produces several attributes that must be improved, namely attributes A1, A4, B4, C2, C4, D4 in quadrant A.

Abstract

The most common lifestyle change during the Covid-19 pandemic is an increase in people's purchasing power. The strategy that sellers need to pay attention to is product placement. Product placement in stores on a small or large scale is one of the strategies that can affect consumer purchasing decisions. One supermarket in Surabaya experienced an increase in transactions during the pandemic, but there are some products whose sales are not as high as other products due to product placement that is not by the type or function so that when customers want to buy products they have to look for them first, this is not uncommon. customers do not shop or buy products which result in lower transactions and lower supermarket profits. So this research was conducted to provide recommendations for product placement in a layout that suits consumers' wishes, grouping products based on consumer buying habits, and reduce search time. This research was conducted using the Market Basket Analysis (MBA) method. From the results, there are 19 rules which indicate that some products will be purchased if placed close to other products with a 100% confidence level.

Abstract

In line with the current development of society, the need for electricity can be said to be a primary need that must be met to support community activities, both for economic purposes and to fulfill daily household needs. The research was conducted at one of the power generation companies. Based on the results of initial observations and interviews with workers at the company, it was explained that the potential danger of work accidents in the boiler machine area at the Steam-Electric Power Station was considered high. Dangers of work accidents that can occur in the boiler area include hot weather, noise, sparks, water vapor leaks, contact with hot steam pipes, high pressure, slipping, and falling from heights. The danger that has occurred in the boiler machine area is noise, noise often occurs because workers underestimate the use of earplugs or earmuffs because they feel they often work without using earplugs. This research aims to analyze the potential dangers of work accidents in the PLTU boiler machine area in the company. Analysis of potential accident hazards was carried out using the HAZOP method. It is hoped that the HAZOP method will enable researchers to know the dangers and how to overcome them to minimize the risk of occupational hazards. This method has the advantage that work using this method will run systematically, the results obtained are more detailed compared to other methods and can be used in various systems. The results of the research show that the risk of danger in power generation companies amounts to 12 potential work accident hazards. Potential dangers of work accidents consist of deafness (25%), burns (17%), slips (9%), shortness of breath (9%), dehydration (8%), electric shock (8%), pinching (8%), fire (8%), and corrosion (8%).
