Quality public service is what is called the best service that meets service quality standards. Service standards are the benchmarks used as guidelines for the delivery of service and the reference for evaluating the quality of service as the obligation and promise of the service providers to the community in the context of quality, fast, affordable, and measurable service. The purpose of this study is to assess the quality of public service at the Maniangpajo Subdistrict office and to identify the factors affecting the quality of public service at the Maniangpajo Subdistrict office. This research uses a qualitative method with a population of 5 individuals, consisting of civil servants (2 people) and the public (3 people). Data collection was done using observation, interviews, and documentation techniques, while the data analysis technique used in this study is qualitative analysis, specifically the interactive analysis technique.The results of this study show that the service at the Maniangpajo Subdistrict office is considered good by service users because the staff are proactive in providing information and the waiting room is comfortable. Although there are no specific SOPs in place, they apply service standards in accordance with government regulations. However, issues such as limited human resources and the unavailability of ID card forms cause delays in service.For internal factors, it can be concluded that the main obstacle to service delivery at the Maniangpajo Subdistrict office is frequent internet network disruptions. These disruptions slow down the service process that requires internet connectivity. Additionally, internal factors such as the limited number of service personnel also affect the efficiency of service, especially when many service users are present, resulting in long waiting times.

The problem of household waste, which accounts for 50-70% of the total waste in Indonesia, mainly in the form of organic waste such as food and vegetable scraps, is a major challenge in environmental management. Composting is an effective method of managing organic waste by turning it into compost. However, organic waste management in Indonesia is still minimally practiced because it is considered to have no economic value. A 50 kg capacity composter machine equipped with a vertical mixer and using an electric motor can increase composting efficiency. This study aims to analyze the feasibility of composter machines and to analyze the effect of speed and mixing time on composter machines on the homogeneity of organic waste. The research method used is quantitative experimental with factorial experimental design (DOE) to analyze the effect of speed and stirring time on the composter machine on the homogeneity of organic waste. The stirring speed variations tested were 30, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the single mixer composter machine proved to be feasible and reliable in producing homogeneous organic waste, with a high process capability value of 5.86. The use of mixing speed from 30 RPM to 60 RPM and mixing time from 20 minutes to 40 minutes significantly increased the homogeneity of organic waste, with the highest value of 97.54% at 60 RPM speed for 40 minutes.

This paper presents an IoT-enabled dual-axis solar tracking system that integrates  a Kalman filter and a Proportional-Integral-Derivative (PID) controller to enhance tracking accuracy, energy efficiency, and operational stability. Addressing the ongoing challenge of maxi- mizing photovoltaic (PV) panel output, the proposed system leverages an ESP32 microcontroller and the Blynk platform to provide real-time monitoring, remote parameter adjustments, and flexible connectivity. Light Dependent Resistor (LDR) sensors measure sunlight intensity from multiple directions, while MG90S servo motors dynamically adjust the panel’s azimuth and elevation. The Kalman filter refines noisy sensor data to yield precise sun position estimates, enabling the PID controller to respond quickly and accurately to deviations in panel orientation. Through extensive testing conducted over several days, including both clear and partially cloudy conditions, the system achieved an average Root Mean Square Error (RMSE) as low as 1.2° under clear skies and maintained RMSE below 2.0° even under partial shading. Compared to a fixed-panel baseline, daily energy harvesting improved by approximately 43%. These results confirm that advanced estimation and control algorithms, when combined with IoT functionali- ties, significantly outperform simpler tracking methods and static installations. Furthermore, the low-cost, compact design and user-friendly interface facilitate practical deployment in a range of scenarios, including small-scale and off-grid installations. By ensuring continuous alignment of the PV panel with the sun, the system not only increases overall energy capture but also reduces maintenance requirements through remote oversight. This research thus offers a robust, scalable approach to improving solar energy utilization in diverse and evolving environmental conditions.

All companies hope for an effective and efficient production system, but an imperfect production system means that PT XYZ must improve its production activities. The company strives to produce good products followed by a high level of productivity. In this research, we investigate a case at PT XYZ which produces hot stamping foil in the rewind section. This research found that there was waste that occurred in set-up replacement activities in production. Because it requires a long processing time, we perfected the system by implementing the Single Minute Exchange of Dies (SMED) method, then the process optimized internal activities in the set-up process. The application of the SMED concept is carried out by changing internal activities into external activities with the addition of helpers. This research aims to provide a more effective and efficient set-up replacement process so that machine downtime can be reduced. The results of this research show a 52% reduction in set-up time obtained by adding a helper with a time before implementation of 58 minutes to 30 minutes. This research concludes that SMED is effective in reducing machine set-up time and increasing the efficiency of the production process with benefits after implementing the SMED method by adding a helper of Rp. 10,649,336. In this way, implementing the SMED method helps companies increase production set-up replacement times in the rewind section.  

This study explores the marketing strategies used by traders in Pasar Besar, Pasuruan City in dealing with changes in consumer behavior in the digital era. Data were obtained through semi-structured interviews and questionnaires, involving traders representing various types of products and marketing methods. Analysis was conducted qualitatively to explore key themes and quantitatively to identify patterns and trends. The results show that traditional marketing (direct selling) is still relevant because direct interaction creates emotional connections and increases buyer loyalty. However, this approach faces challenges due to the shift in buyer preferences to online shopping. Meanwhile, online marketing offers wider market reach, cost efficiency, and time flexibility, although its success is highly dependent on promotional capabilities and delivery management. The combination of traditional and online strategies has proven effective in reaching various buyer segments, providing significant sales increases. This approach requires careful planning to optimize the benefits of both methods without increasing operational costs. By understanding market needs and adjusting strategies, traders can maximize the potential of both approaches to achieve success amidst changing times.
