In an increasingly competitive business environment, employee performance is a crucial factor in determining the sustainability and competitiveness of a company. Employee performance is influenced by several factors, such as leadership style and work environment. This study focuses on PT Sinergi Adimitra Jaya, a manufacturing company specializing in the production of baby and adult diapers, to analyze the influence of these factors on employee performance with job satisfaction as a mediating variable. The research approach used in this study is a quantitative approach. Data collection was carried out by survey using questionnaires distributed to 102 employees. The sampling technique used saturated sampling. The data collected were then analyzed using SEM-PLS (Structural Equation Modeling-Partial Least Squares) through SMART PLS 4.0 software. The analysis includes outer and inner models to assess validity, reliability, and relationships between variables. The results of the study indicate that leadership style has a positive and significant influence on employee performance. However, job satisfaction does not significantly mediate the relationship. Conversely, the work environment does not have a significant direct influence on employee performance. Job satisfaction does not mediate its influence. The evaluation of the model resulted that leadership style and work environment explained 38.1% of the variability in job satisfaction, while 31.2% of the variability in employee performance was explained by leadership style, work environment, and job satisfaction.

PT KUI (Komatsu Undercarriage Indonesia) memproduksi berbagai komponen undercarriage untuk alat berat khususnya excavator dan bulldozer. Komponen utama yang diproduksi antara lain link assy, shoe assy, roller, carrier, sprocket, shaft, dan segment teeth. Roller merupakan salah satu komponen yang terberat. Komponen tersebut diproduksi melalui proses forging dengan berat material hingga 112 kg pada temperatur antara 1150-1250°C. Pada kondisi tersebut, terdapat kemungkinan terjadinya deformasi plastis yang dapat menimbulkan cacat produk yang dikenal dengan istilah dakon. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis sumber permasalahan dengan menerapkan metode FMEA (Failure Mode and Effect Analysis). Melalui pendekatan tersebut, diperoleh RPN (Risk Priority Number) yang menjadi dasar utama dalam menentukan prioritas perbaikan yang diperlukan untuk mengurangi cacat dakon. Hasil penelitian menunjukkan bahwa penerapan kaizen yang meliputi penambahan kipas pendingin untuk mencapai suhu optimal, pengaturan kecepatan konveyor, dan standardisasi prosedur mampu menurunkan cacat dakon secara signifikan dari 39,7% menjadi 0% (zero dakon).

Nowadays, there are many online travel agencies (OTAs) in Indonesia that provide various options for their customers. Before choosing which OTA to use, customers usually check each platform to ensure that they offer the best service. Traveloka is the most preferred OTA app by 67.5% of respondents. Google Play Store reviews show that users are still confused with information such as pricing and proper payment. Some features do not work properly when making hotel reservations. User Experience Questionnaire is used to quickly measure the user experience level of the product. Attractiveness, perspiculty, efficiency, accuracy, stimulation, and novelty were the six UEQ scales used. A random sample of one hundred app users was selected. The results showed that each scale was overall excellent. The criteria of attractiveness 2.485 ? 1.750, perspiculty 2.290 ? 1.900, efficiency 2.448 ? 1.780, dependability 2.338 ? 1.650, stimulation 2.393 ? 1.550, and novelty 2.293 ? 1.400. This research achieves the objectives or features of the application in terms of design, systems, and services. the result is that the Traveloka application can improve perspiculty with existing functions, so that the hotel booking process becomes easier to understand, easy to learn, simple, and clear.
