Abstract

Generasi Milenial menghabiskan 85% waktunya di depan gadget, cenderung kurang olahraga, dan makan makanan cepat saji dengan nilai gizi rendah. Hal ini memberikan pengaruh kurang baik pada kesehatan. Beragam inovasi makanan dihadirkan sebagai pilihan untuk memenuhi kebutuhan makan. Saat ini banyak bermunculan varian olahan makanan dari luar negeri yang tinggi kalori, namun rendah protein dan vitamin. Salah satunya adalah salad buah yang disajikan dengan mayonaise tinggi kalori, susu tinggi gula, dan keju tinggi lemak. Sedangkan, Indonesia sendiri memiliki cara menikmati buah segar yang menyehatkan, yaitu rujak buah dengan bumbu kacang dan gula merah. Namun, kendala pembuatannya tidak praktis, sehingga kurang diminati. Melihat kondisi ini, Cak Mimin yang merupakan UMKM di Surabaya merintis bumbu rujak manis praktis. Bumbu Rujak Manis Cak Mimin cukup diminati masyarakat, mengingat budaya rujakan umum dilakukan masyarakat. Produk ini hadir dalam kemasan 250 gr dan 500 gr. Guna melebarkan pasar ke Generasi Milenial, maka dilakukan repositioning keunggulan produk. Pengembangan produk dilakukan dengan konsep Kansei Engineering yang mempelajari perilaku dan mendapatkan informasi kebutuhan konsumen. Selanjutnya dikembangkan alternatif pengembangan produk yang sesuai. Harapannya dengan adanya produk baru yang dihasilkan hasil repositioning ini, maka Bumbu Rujak Manis Cak Mimin dapat diterima Generasi Milenial untuk menghadirkan makanan yang sehat dan kaya gizi.

Abstract

A Mixed Reality device is a new technology that provides immersive training experiences. One of the mixed reality technology with high immersion, high interaction, and high information is Microsoft Hololens 2. Smart glasses are classified as OST-HMDs (Optical See-Through Head-Mounted Displays), which display augmented objects in a mixed-reality environment. The use of HMDs can cause cybersickness symptoms that users feel. This study aims to assess the human performance and cybersickness of Hololens 2 for immersive training. The training object was an augmented assembly engine comprising six parts. Using Hololens 2 as an assembly simulator training, participants experienced a significant increase in performance and learning rate with minor errors. Hololens 2 produces light symptoms that the user perceives as general discomfort, fatigue, difficulty focusing, sweating, difficulty concentrating, and blurred vision. However, Hololens 2 experienced negligible symptoms based on the cybersickness factor: Nausea (3.98), Oculomotor (6.32), and Disorientation (2.32). Based on the SSQ scoring matrix assessment, Hololens 2 obtained an SSQ score of 4.48, which is classified as a minor symptom of cybersickness.

Abstract

This study aims to analyze the effects of safety knowledge, safety leadership, and safety attitude on supervisor competence, safety motivation, and safety compliance, as well as to examine the mediating role of safety motivation in the relationship between supervisor competence and safety compliance in power infrastructure projects managed by PT PLN (Persero) Pusat Manajemen Proyek. This study employed a quantitative approach using Partial Least Squares–Structural Equation Modeling (PLS-SEM). Data were collected through a questionnaire using a six-point Likert scale and distributed to employees and outsourced personnel with at least two years of work experience. Of the 160 questionnaires collected, 126 responses met the predetermined criteria and were included in the analysis. The measurement model evaluation confirmed that all research indicators satisfied the validity and reliability requirements. The results indicate that safety attitude and safety motivation have positive and significant effects on safety compliance, with safety motivation demonstrating the strongest influence. Safety knowledge and safety attitude also have positive and significant effects on safety motivation, while safety leadership does not show a significant effect. Furthermore, safety knowledge and safety attitude positively and significantly influence supervisor competence, with safety knowledge emerging as the most dominant factor. These findings suggest that improving OHS compliance at PLN Pusmanpro should focus on strengthening safety motivation and safety attitude, enhancing practical and job-relevant safety knowledge, and developing supervisor competence and safety leadership through more visible and consistent practices in the field.

Abstract

Occupational Safety and Health (OSH) implementation in the electricity transmission sector remains a critical issue due to the high level of workplace risks, including electrical hazards, work at heights, and dynamic field conditions. Strengthening OSH practices requires an understanding of the factors influencing workers’ safety behavior. This study aims to identify and examine the factors affecting OSH implementation in the electricity transmission sector by analyzing the relationships among safety knowledge, safety culture, safety leadership, safety attitude, and safety citizenship behavior. A quantitative approach was employed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method. Data were collected through questionnaires distributed to 125 employees and outsourced personnel within the transmission management unit of PT PLN (Persero). The research model was evaluated through measurement model and structural model assessments, including validity, reliability, coefficient of determination (R²), predictive relevance (Q²), effect size, goodness-of-fit evaluation, and hypothesis testing using bootstrapping analysis. The results indicate that seven out of the eight proposed hypotheses were supported. Safety knowledge, safety leadership, and safety attitude significantly influenced safety citizenship behavior, with safety leadership demonstrating the strongest effect on safety culture (? = 0.575), and safety attitude significantly affecting safety citizenship behavior (? = 0.544). However, safety culture did not significantly influence safety attitude. The findings highlight that improving OSH implementation requires strengthening safety leadership, enhancing safety knowledge, and developing positive safety attitudes among workers. This study provides strategic recommendations for improving safety programs and supporting the achievement of zero accidents in the electricity transmission sector.

Abstract

The purpose of this study is to explore Generation Z's perspective on utilizing social media information to apply for jobs via company employer branding. This quantitative study uses Least Square-Structural Equation Modeling (PLS-SEM) with a second-order research model to examine the influence of social media, employer branding, and competitive advantage on the interest in job applications and corporate reputation. Data was collected through a self-administered questionnaire using a 5-point Likert scale, distributed to 211 Generation Z respondents using the Lemeshow approach. Seven hypotheses were tested: (1) social media significantly affects job application interest; (2) employer branding significantly affects job application interest; (3) competitive advantage significantly affects job application interest; (4) job application interest significantly affects corporate reputation; (5) social media significantly affects corporate reputation; (6) employer branding significantly affects corporate reputation; (7) competitive advantage significantly affects corporate reputation. The study’s results indicate that all hypotheses were accepted, except for hypothesis (4). The practical implications include offering companies valuable insights on effectively using social media in employer branding to boost applicant engagement.
