This study aims to analyze the influence of employer branding and work experience on employee retention at PT Tanto Intim Line Jakarta. The research background indicates that, in the era of globalization, companies face intense competition, making human resource management, particularly employee retention, crucial for achieving organizational goals and avoiding declines in employee performance due to turnover. Employer branding and work experience are identified as essential factors influencing employees' decisions to stay within an organization. This research method uses a quantitative approach, with a case study of employees at PT Tanto Intim Line Jakarta. The research population consists of all 100 employees of PT Tanto Intim Line. Data were collected through questionnaires and analyzed using multiple linear regression. The results of the validity and reliability tests show that all research instruments are valid and reliable. The research results indicate that employer branding has a significant positive partial effect on employer retention. Similarly, work experience also has a significant positive partial effect on employer retention. Furthermore, simultaneously, employer branding and work experience have a significant effect on employer retention. These two variables account for 12.8% of employer retention, while factors outside the research model account for the remaining 87.2%. This research provides an in-depth understanding of the importance of both factors in retaining competent employees.

Jengki architecture is a distinctive manifestation of Indonesian modernism that emerged in the 1950s, shaped by the post-independence spirit and a deliberate rejection of colonial aesthetic dominance. In the same period, Indonesian cinema developed as a visual medium capable of recording social change, cultural transformation, and shifting urban lifestyles. This study investigates the representation of Jengki architectural interiors in Tiga Dara (1956), directed by Usmar Ismail, using a cinematic approach and Roland Barthes’ semiotic analysis. Employing a qualitative descriptive method, the research draws on literature review, frame-by-frame visual observation, and documentation of film scenes featuring interior spaces. The analysis identifies denotative and connotative meanings of interior elements, including spatial layout, architectural components, lighting, ventilation, furniture, and furnishings as part of the film’s mise-en-scène. The findings reveal that Jengki interiors are represented through asymmetrical spatial compositions, flexible layouts, slanted forms, climatic responsiveness, and hybrid furniture influenced by international modernism. At the connotative level, these visual representations articulate ideas of modernity, freedom, innovation, and national optimism in the construction of post-independence identity. This study highlights the role of film as a valuable visual archive for understanding the development of interior design and architectural discourse in Indonesia’s transition toward national modernity.

Cast titanium is widely used in advanced engineering applications due to its high strength-to-weight ratio and good corrosion resistance. However, its mechanical properties are highly sensitive to variations in the alloy's chemical composition, making conventional testing less efficient in terms of time and cost. This study aims to predict the mechanical properties of cast titanium, namely yield strength and tensile strength, based on the alloy's chemical composition using a machine learning approach. The dataset was obtained from the Materials Algorithms Project (MAP) with 100 cast titanium specimens developed through small and controlled variations in chemical composition to represent realistic manufacturing conditions. Modeling was performed using Decision Tree and Random Forest algorithms with data splitting schemes of 60:40, 70:30, and 80:20 and k-fold cross validation. Model performance evaluation was performed using Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and coefficient of determination (R²) metrics. The results of the Pearson correlation analysis showed that Al, V, and Fe-X elements have a strong positive correlation with mechanical properties, while Ti and O show a significant negative correlation, which is in line with the theory of titanium alloy metallurgy. The modeling results show that the Random Forest algorithm provides the best performance with lower prediction errors and better stability compared to Decision Tree. This study proves that the machine learning approach, especially the Random Forest algorithm, is effective in predicting the mechanical properties of cast titanium based on chemical composition, with the best performance shown by the RMSE value of 70.95 and MAE of 47.95, thus potentially supporting the design and optimization of cast titanium alloys based on data.

The gearbox in a chain bucket elevator system is a critical component of the cement production process and relies heavily on the reliability of the lubrication system. As operating hours increase, lubricating oil quality degrades, potentially affecting its remaining useful life (RUL). This study aims to analyse the linear relationship between oil-test result parameters and Remaining Useful Life (RUL) for chain bucket elevator gearboxes using the Pearson correlation method. The data used are 50 laboratory test results for the gearbox oil chain bucket elevator at Cement Mill Indarung VI, PT. Semen Padang collected from June 2019 to October 2025. The oil testing parameters analysed include DV Visc 40°C, DV Visc (%), ISO >6, NAS, Contamination Index, Ferrous Index, Chemical Index, Dielectric, and % Water. Data were analysed using the Pearson correlation method and visualised as a heatmap. The analysis results showed that the viscosity parameter had the strongest negative correlation with RUL, with a value of -0.741 for DV Visc 40°C and -0.658 for DV Visc (%). The Contamination Index and % Water parameters also showed a negative correlation with RUL, albeit with a lower level of influence. In practice, the results of this study can serve as a basis for oil condition monitoring to support condition-based maintenance strategies, enabling more timely oil change decisions and minimising the potential for gearbox failure.

The development of manufacturing technology demands mastery of precise and efficient CNC lathe machines, but direct practice is often hampered by limited facilities, operational costs, and the risk of programming errors. This study aims to implement CNC lathe simulation based on Nanjing Swansoft CNC Simulator (SSCNC) in the manufacture of paper weight products as a medium for program verification and learning. The research methods include product design, machining parameter calculation, CNC program preparation using G-Code and M-Code based on FANUC 0i-T control, and testing through two machining stages. The workpiece has an initial diameter of 50 mm and a length of 54 mm with a chuck exit length of 40 mm at each stage. The cutting parameters used are a spindle speed of 1000 rpm and a feed rate of 0.5 mm/rev with an absolute programming system (G90). The tool configuration consists of a VNMG 350 carbide turning tool, an Ø18 mm drill, and a 2 mm internal grooving tool. The simulation results show that the two-stage program can be run without syntax errors, interpolation alarms, or tool path conflicts. The G02/G03 circular interpolation successfully generated a continuous radius, and all geometric features were formed according to the working drawings. The SSCNC simulation proved effective as a safe technical verification and learning medium before practicing on a real CNC machine.

The increasing need for fast delivery drives the development of drones as an alternative logistics solution. However, increasing payload capacity impacts thrust requirements, power consumption, and structural stability, necessitating integrated mechanical design. This study aims to design a mechanical system for a 2-3 kg package delivery drone with a stable and energy-efficient quadcopter configuration at maximum payload conditions. The method used is a design engineering approach through 3D CAD modeling, mass distribution and center of gravity (CoG) analysis, and thrust and power estimation using momentum theory. Evaluations were carried out on the total system weight, hover thrust requirements, hover power, and peak power with a thrust-to-weight (T/W) ratio of 1.8-2.0. The results show that at a total mass of ±6.5 kg, a minimum thrust of approximately 1.63 kgf per motor is required for stable hovering. The estimated hover power is around 1.04 kW, while the peak power is close to 3 kW. The 6S 15,000 mAh battery configuration is capable of providing a hover duration of approximately 15 minutes. This design demonstrates technical feasibility for medium-scale logistics drone applications.

Closed circulation aquaponic systems require proper piping design and pump selection to ensure flow stability, energy efficiency, and operational sustainability. This study aims to design and experimentally validate an aquaponic piping system based on major and minor head loss analysis and determination of Total Dynamic Head (TDH) as the basis for pump selection. The methods used include theoretical calculations using the Darcy Weisbach Equation, system curve construction (HQ), and experimental testing through measurements of actual discharge, pressure, and pump electrical power under real operating conditions. The results show that minor head loss dominates the total energy loss (±66%), while major head loss contributes ±34%. The system TDH is obtained at ±2.2-2.4 m at a design discharge of 24 L/min. Experimental testing shows an actual discharge of 22–23 L/min with a deviation of <8% from the theoretical calculation. Actual pump power shows operational efficiency in the range of 48–55%. Pipe diameter sensitivity analysis shows that increasing the main diameter by 1 level can reduce head loss by 18–25% and reduce pump power requirements by ±12%. These results confirm that optimizing fitting layout and diameter selection has a greater impact on system efficiency than simply increasing pump capacity. This research contributes a system curve-based design approach and experimental validation to improve the reliability and energy efficiency of closed-circulation aquaponics systems.

The use of Rotary Actuators in Industrial Automation systems requires adequate mechanical protection to ensure product quality, system reliability, as well as component durability and safe operation. However, many of the existing machine designs and assembly processes do not fully take into account structural strength, precision quality, ease of adjustment, and maintenance efficiency. This study aims to develop and design the assembly process of high-quality cartridge covers along with their installation system for rotary robotic actuators, taking into account aspects of quality, safety, functionality, and practical implementation. The research methodology includes a literature review, cause analysis, testing, and evaluation. Testing was conducted based on defect rate and the accuracy and precision of the system. The evaluation results showed a significant performance improvement after replacing the pneumatic actuator systems with electric actuators and making mechanical design improvements. Repeatability increased by about 87.6%, the defect rate measured by DPPM decreased by about 92%, and the safety factor reached 2.4, indicating a strong mechanical safety margin. In addition, the operation cycle time remains stable, supporting production needs without compromising reliability. The decrease in DPPM itself is a manufacturing quality metric that measures the number of defective units per one million productions, commonly used to assess the quality and reliability of the production line. These findings confirm that the cartridge cover assembly and installation design developed provides better mechanical protection, facilitates installation, and reduces product defects. Thus, the rotary electric actuator is superior in reducing DPPM and the level of precision.

This study aims to analyze the influence of work motivation, knowledge sharing, organizational support, and creativity on teacher innovation in public elementary schools in Tasikmalaya Regency. The research employed a mixed-method approach using the POP-SDM model, where research variables were initially explored qualitatively and subsequently tested quantitatively. The study involved 163 respondents drawn from 49 public elementary schools. Data were collected through questionnaires and supported by qualitative exploration to obtain a more comprehensive understanding of the relationships among variables. The data analysis techniques included descriptive statistical analysis and hypothesis testing using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The findings revealed that four direct effect hypotheses were accepted, indicating that several independent variables significantly influenced teacher innovation, while three direct hypotheses were rejected due to insignificant relationships. Furthermore, in the indirect effect analysis, one hypothesis was accepted and two were rejected, suggesting that not all mediating relationships were effective in explaining teacher innovation. The results highlight the importance of strengthening creativity, organizational support, and knowledge-sharing practices to improve teacher innovation in educational institutions. This study contributes to the development of human resource management and educational innovation strategies, particularly in enhancing teacher performance and innovation in elementary schools.

Silence and omission play a significant role in discourse, particularly in representing complex experiences such as trauma; however, they are often overlooked as meaningful linguistic elements. While previous studies have examined trauma in literary texts, limited research has analyzed how silence and omission are systematically realized at the clause level and interpreted through a socio-cognitive perspective. This study addresses that gap by investigating the linguistic realization and functions of silence and omission in Hanya Yanagihara’s A Little Life. This research employs a qualitative descriptive design with clause-level analysis as the unit of investigation. The data consist of 387 clauses selected through a systematic data reduction process from an initial dataset, focusing on expressions that reflect silence, omission, avoidance, and indirect discourse. The analysis applies a socio-cognitive discourse framework to interpret how these linguistic patterns relate to mental processes and social interaction. The findings show that silence and omission are realized through various forms, including explicit silence, vague or incomplete expressions, avoidance strategies, non-verbal communication, and minimal responses. The distribution of data indicates that cognitive and emotional processing is the most dominant pattern (39.8%), followed by silence and non-verbal expression (18.3%), avoidance and deflection (15.0%), omission and concealment (13.7%), and socio-discursive regulation (13.2%). These results demonstrate that silence and omission function as mechanisms for expressing unspoken trauma through cognitive limitation, emotional suppression, and socially regulated interaction. This study contributes to discourse analysis by demonstrating that meaning is constructed not only through explicit language but also through absence and indirect expression. It also highlights the relevance of a socio-cognitive approach in understanding how language, cognition, and social context interact in representing trauma.
