Abstract

In 2022, the coal production industry encountered unprecedented challenges accompanied by a substantial global commodity price surge. The operational impact of this situation surpasses current technological capabilities of coal companies, particularly in optimizing coal blending scenarios. A pivotal aspect of digital transformation involves integration of new digital platform for production planning. This study employs the Unified Theory of Acceptance and Use of Technology in conjunction with decision theory to identify key factors influencing the platform adoption at a coal mining company. Structured questionnaires were utilized, followed by analysis using the SmartPLS 4.0.9.9 software. Findings reveal that both Performance Expectancy and Effort Expectancy positively influence users’ behavioral intention to adopt digital platform for production planning. Behavioral Intention, in turn, significantly impacts actual usage behavior. Unanticipated situational factors and others' attitudes were found to have negligible mediating effects, while variables such as age and experience showed no moderating influence on the pathways from behavioral intention to usage behavior. Companies are advised to improve digital platform performance through functionalities enhancements and pilot testing to reduce perceived effort and stimulate behavioral intention. Additionally, fostering a positive organizational mindset through routine motivational communications can further stimulate usage behavior.

Abstract

Dogs are common companion animals, and free-roaming dogs living in close proximity to humans may increase the risk of zoonotic disease transmission. One of the parasitic diseases of concern is toxocariasis, caused by nematodes of the genus Toxocara. Infection in animals may result in diarrhea, dehydration, anemia, and, in severe cases, death. This study aimed to detect the presence of Toxocara sp. eggs in fecal samples collected from stray dogs in the Kembang Kuning Cemetery area, Dukuh Kupang, Dukuh Pakis District, Surabaya. A total of 28 fecal samples were collected and initially examined using the native method. For each sample, 1 g of feces was mixed with 10 mL of distilled water, and 1–2 drops of the suspension were placed on a glass slide, covered with a coverslip, and examined microscopically. Twenty samples that were positive on native examination were subsequently tested using the flotation method. The fecal suspension was centrifuged at 3000 rpm for 10 min, repeated 2–3 times until the supernatant became clear. The sediment was then mixed with saturated sugar solution, covered with a coverslip, left for at least 20 min, and examined under a microscope at 400× magnification. The flotation test detected Toxocara sp. eggs in 17 of the 20 native-positive samples, equivalent to 85.0% of native-positive samples and 60.7% of all collected fecal samples. Three of the 17 Toxocara sp.-positive samples also contained Ancylostoma sp. eggs, indicating mixed infection. These findings demonstrate the presence of gastrointestinal helminth contamination in stray dog feces in the study area and highlight the potential zoonotic risk to the surrounding community.
