Abstract

The development of cellular communication technology has reached a significant point with the presence of 4G LTE networks, which offer high speed and spectrum efficiency. This study aims to evaluate the performance of 4G LTE networks from two operators, Telkomsel and Axis, at two locations of Sultan Ageng Tirtayasa University (UNTIRTA), namely Campus A and Campus C. The method used is a drive test with the help of the SpeedOf.me site, which measures download speed, upload speed, and latency parameters. The test results show that Telkomsel excels in upload speed with relatively good latency stability, while Axis has the advantage in the highest download speed but shows large fluctuations in performance, especially in the latency parameter. This performance variation indicates that location factors, network load, and device conditions greatly affect service quality. Overall, Telkomsel shows more stable performance, making it more reliable for network-based academic activities, while Axis is suitable for needs with a priority of download speed in optimal conditions. This study is expected to be a reference for the development of network infrastructure in higher education environments.

Abstract

Ports are critical infrastructure in maritime transportation, facilitating the movement of goods and people while serving as hubs for economic activities. The Tanjung Pakis Class III Harbormaster and Port Authority Office (KSOP) utilizes the Electronic Reporting Information (SIRANI) application for reporting loading and unloading data. However, challenges such as discrepancies, technical disruptions, and delays in data processing often arise. This study aims to describe the loading and unloading data processing and the efficiency of reporting time on the SIRANI application at KSOP Class III Tanjung Pakis. Employing a descriptive qualitative approach through interviews, observations, and documentation, the research finds that data processing is less effective due to low data validity and errors in the Inaportnet platform. Reporting to SIRANI is also inefficient due to delays in data handling and technical issues with the application. Corrective measures, such as early data verification and manual data handling by reporting officers, have improved effectiveness by reducing the process from five to three steps and cutting reporting time from 6 hours to 3 hours and 30 minutes. The study concludes that optimizing data processing and inter-unit coordination can enhance the effectiveness and efficiency of reporting. Recommendations for future research include real-time integration and the development of backup mechanisms to address technical disruptions.

Abstract

One of the key processes in the production of APAR cylinders is the welding of cylindrical plates, which is carried out using a Longitudinal Welding Cylinder machine and the CO₂ welding method. However, in practice, operators face several challenges, mainly due to the number of process steps that do not significantly contribute to the quantity or quality of the output, resulting in reduced productivity. This study aims to improve the productivity of the welding process through a series of improvements. The methods used include data analysis and root cause identification through the Overall Equipment Effectiveness (OEE) approach and Lean Six Sigma using the DMAIC stages (Define, Measure, Analyze, Improve, Control). Based on the Define stage, the initial OEE value was 67.49%, which is still far below the world-class standard of 85%. In the Measure stage, Pareto analysis revealed that the largest downtime (2,097 minutes or 40%) was caused by cycle time issues. Further analysis showed that activities such as material setup, additional plate placement, and additional plate cutting (totaling 85 seconds) could still be optimized. During the Improve stage, modifications were made, such as eliminating the additional plate cutting process and adding a stopper to ensure accurate welding alignment. These improvements successfully reduced the cycle time from 180 seconds to 120 seconds, thereby decreasing downtime and increasing the OEE value to 76.12%.

Abstract

Spring steel is one type of material that is widely used in various engineering applications, such as vehicle suspension systems and equipment that require resistance to dynamic loads. Spring steel possesses various mechanical characteristics that are strongly influenced by the microstructure of the material. These characteristics remain consistently affected throughout the entire material. Heating that occurs due to exposure to flame can alter certain microstructural properties of spring steel and affect its performance. In this study, an analysis was carried out on all changes in the microstructure of spring steel caused by flame heating, as well as its effect on the hardness of the material. The results of the study showed that heating can indeed cause changes in the microstructural phase and a decrease in fatigue resistance of the spring steel.

Abstract

This study discusses the arrangement of queue lanes in the supervision of weighing freight transportation at UPPKB Singosari to improve service efficiency. Based on the analysis of the Minimum Service Standards (SPM), three main indicators, namely compliance, conformity, and implementation, have reached 100%, while the accuracy indicator has only reached 50% due to the duration of weighing exceeding the set time limit. The main factor causing long queues is the lack of clear lane markings, making it difficult for vehicles to be directed without an officer. In addition, the parking area of 3,330.6 m² has not been utilized optimally. Improvement efforts include the implementation of queue lane markings to reduce dependence on officers, optimization of facilities such as Pos 2 which is parallel to Pos 1, and improvement of human resource management to suit operational needs. The use of Weight in Motion (WIM) technology is also recommended to reduce workload and accelerate the supervision of freight transport vehicles. By implementing this strategy, it is hoped that services at UPPKB Singosari can be more efficient, transparent, and in accordance with applicable standards.

Abstract

This study discusses the architectural transformation of Pasar Johar Semarang before and after the major fire incident in 2015. Designed by architect Thomas Karsten, Pasar Johar holds significant historical and architectural values. The fire prompted a comprehensive revitalization of the market’s environment, site, and building while maintaining its original character. This research employs an architectural anatomy approach covering three main scopes: environment, site, and building, and uses a qualitative descriptive-analytical method through four stages: (1) documenting conditions before and after the fire, (2) classifying architectural elements, (3) comparing visual and structural transformations, and (4) drawing conclusions based on the analysis to evaluate the extent of the transformation. The results show that the revitalization made the area more organized, functional, and sustainable. Distinctive structures such as mushroom columns and drainage systems were preserved, while zoning and public spaces were reorganized to improve efficiency and comfort. This restoration not only improved physical aspects but also strengthened the market’s social function as a community interaction space. Pasar Johar now serves as an example of a traditional market that can adapt to modern urban challenges without losing its architectural identity and its potential as a sustainable economic and social hub.
