Abstract

Copra meal flour is used as a fish feed ingredient with a fairly high protein content of 18–24%. However, its crude fiber content is high, which can reduce its digestibility. Therefore, fermentation is needed to improve the quality of copra meal. This study aims to determine the percentage of copra meal flour fermented with EM4 in feed to produce the best feed efficiency and growth of gorami fish. This study employed an experimental method with a completely randomized design (CRD). Five types of feed were formulated to contain 32% protein, with feed P0 containing 100% soybean meal (control feed), and feeds P1, P2, P3, and P4 replacing soybean meal with fermented copra meal at 25%, 50%, 75%, and 100%, respectively gorami fish fry (with an average body weight of 2.08 ± 0.11 g) were stocked in floating net cages measuring 1 × 1 × 1 m3 at a density of 25 fish per cage. The experimental feed was given at 10% of the test fish biomass frequency three times a day at 08.00, 12.00, and 16.00 WIB, for 56 days. Feed digestibility was measured by giving the test feed three times a day to satiation, mixed with Cr2O3 and protein. The results showed that the use of TBKF in the feed significantly improved feed efficiency and gorami fry growth. Based on the results, it can be concluded that the use of 75% fermented copra meal can replace soybean meal in gorami feed, with feed digestibility (57.63%),  protein digestibility (80.08%), protein retention (37.56%), feed efficiency (52.31%), and specific growth rate (4.05%).

Abstract

Human resources play a crucial role in realizing the company's established vision, mission, and objectives, and can significantly determine the company's actual achievements, given the available resources. Work discipline plays a crucial role in realizing the company's established vision, mission, and objectives, and can significantly determine the company's actual achievements given the available resources. The work discipline instilled by an organization or company in its employees greatly influences employees' dedication to their work. Employee performance is the tangible behavior of each individual regarding the results of their work for the company, so that each employee's work results differ from those of others. An individual's performance, whether good or poor, will significantly impact an organization's ability to achieve its goals. High performance fosters greater employee loyalty to the organization, increases motivation, and allows employees to enjoy the work they perform; however, it can sometimes leave individuals unable to escape the pressures of their work.  The research method employed uses questionnaires or interviews for data collection; thus, the data sources are referred to as respondents. Work discipline has a positive and significant influence on employee performance at the Regional Disaster Management Agency (BPBD) office in Pekanbaru City, as evidenced by the t-test, which indicates that the calculated t-value is greater than the critical t-value (7.038).

Abstract

The courier industry in Indonesia has experienced significant growth in recent years, driven by the rapid expansion of e-commerce and increased online shopping activity. This study is based on the fact that many customer complaints regarding J&T services, such as late deliveries, damaged goods, and difficulties communicating with couriers, remain, despite J&T being one of the courier service companies with the highest market share in Indonesia. This study aims to analyze the effects of service recovery on distributive, procedural, and interactional justice. The study was conducted from August to September 2025. The method used was quantitative, with a descriptive approach. Data were collected through questionnaires administered to 100 residents of Pekanbaru City who had used J&T services and experienced delivery-related complaints. The analysis technique used was multiple linear regression in SPSS. The results show that, both partially and simultaneously, distributive, procedural, and interactional service recovery have a positive and significant influence on customer satisfaction. This implies that the better the company handles complaints using an appropriate justice approach, the higher the customer satisfaction
