This study examines the potential for digital branding transformation of Mitra Havana Sulung Mandiri, a construction service company in East Java, through the utilization of TikTok as a promotional platform. Using observations and interviews, the research identified strong visual content opportunities from the company’s activities, such as documenting construction progress, showcasing before-and-after project visuals, and sharing client testimonials. These elements offer significant storytelling potential for engaging online audiences. However, several internal barriers hinder optimal implementation. These include limited digital literacy among staff, inadequate content creation tools, and the absence of standardized procedures for producing and publishing content. Externally, skepticism toward social media marketing in the construction sector and the unpredictability of TikTok’s algorithm also create challenges. Thematic analysis revealed three primary needs: maximizing existing visual assets to create compelling narratives, enhancing internal capacity through targeted digital training, and developing a culture that supports continuous digital engagement. To address these, the study proposes an initial strategy involving educational content, behind-the-scenes videos, and a clear content production guide. In addition, it suggests forming a dedicated social media team, running a 30-day continuous content campaign, and collaborating with local creators to expand reach. These recommendations align with existing literature on the role of short-form video in increasing brand awareness, credibility, and trust in service-oriented industries. By integrating strategic content planning, capacity building, and consistent online engagement, construction SMEs can position themselves competitively in the evolving digital marketplace. The case of Mitra Havana Sulung Mandiri demonstrates that even in traditionally offline industries, leveraging TikTok can offer a pathway toward brand differentiation and long-term audience growth.

Entertainment tax is one type of regional tax that has the potential to increase PAD revenue if managed optimally. The method used in this study is quantitative descriptive with a documentation, observation and interview approach using data on the realization of entertainment tax revenue and total PAD from the Sukoharjo Regency Regional Finance Agency. The results of the study show that the growth rate of entertainment tax has fluctuated significantly from year to year, with the highest growth occurring in 2022 at 261.04% after experiencing a drastic decline during the pandemic. Meanwhile, the contribution of entertainment tax to PAD in general is still very low, below 10% each year, with an average contribution of 0.768%. This finding shows that although entertainment tax has shown positive growth in several years, its contribution to PAD is still not optimal. Therefore, a more effective management strategy is needed so that the potential revenue from this sector can be maximized to support regional development.”

Plastic waste is currently still a serious problem for society due to the lack of sensitivity to environmental problems and the impact of careless disposal of plastic waste in many places. The injection molding process on industry scale often faces obstacles such as machines that have not worked efficiently, injection capacity that is unable to fill the mold completely, and the emergence of product defects due to plastic flow that begins to freeze before the entire cavity is completely filled. This study aims to design and simulate a prototype injection molding machine with a capacity of 4 tensile test specimens (total volume 28.5 cm³) in order to overcome these problems and to adjust the practicum needs of mechanical engineering students. The design process is carried out with SolidWorks software for 3D design, as well as flow simulation using SolidWorks Plastics and Flow Simulation with recycled Polypropylene (PP) material at melting temperature ± 230 ° C and injection pressure ± 5.3 MPa. The design results in a machine with dimensions of 1273 × 400 × 826 mm equipped with main components in the form of a frame, electric motor and gearbox, hopper, body safety, wheels, piston cylinder, control panel, heater, screw with barrel, and mold. SolidWorks Plastics simulation shows that the plastic flow fills the mold evenly with a filling time of 10.93 seconds, cycle time of 83.94 seconds, and maximum pressure of 5.38 MPa in the gate area, while Flow Simulation simulation shows a spiral flow pattern from the hopper to the end of the mold without backflow, with a mass flow rate of 0.0227 kg/sec and an average pressure of 97.765 Pa. These results prove that the design and simulation can improve process efficiency and mold quality

The essential oil of lemongrass (Cymbopogon citratus) is a high-value commodity widely used in the food, pharmaceutical, and cosmetic industries due to its bioactive components such as citral. Optimizing its distillation process is necessary to achieve maximum yield with time and energy efficiency. This study aims to determine the hourly yield distribution of essential oil from Lombong-type lemongrass during steam distillation and to analyze its extraction kinetics to identify the optimal distillation duration. Distillation was conducted for four hours with yield recorded each hour, and the data were analyzed using pseudo-first-order and pseudo-second-order kinetic models. The results showed that the highest yield was obtained in the first hour (0.1882%), followed by a sharp decline, with no additional yield observed in the fourth hour. The pseudo-first-order model showed the best fit to the experimental data with a rate constant of k = 0,8012/hour. Meanwhile the pseudo-second-order model did not fit well. These findings indicate that the extraction process is dominated by external diffusion and the rapid release of surface volatile compounds. Therefore, it is recommended that distillation duration be limited to two hours to optimize energy and time efficiency.
