Abstract

This study analyzes the potential use of cockle shell waste and coal fly ash as alternative raw materials in the production of composite brake pads. The high volume of industrial and fisheries waste, which has not been optimally utilized, encourages the exploration of environmentally friendly materials with adequate mechanical performance. The main focus of this research is the compressive strength of the produced brake pads, as this parameter is crucial for ensuring effective and safe braking performance. The method used includes the mixing and molding of composite materials with varying compositions of cockle shell and fly ash, followed by compressive strength testing according to standards. This study also takes into account the environmental impact of using waste as filler material, which is expected to reduce reliance on conventional materials and decrease waste that contaminates the environment. The results of the study are expected to provide empirical data on the potential of these two wastes as fillers in brake pad matrices and to identify the optimal formulation that provides the highest compressive strength. This study contributes to the development of sustainable braking materials and efforts to mitigate the environmental impact of waste, while also opening opportunities for the reuse of waste that has previously been poorly managed.

Abstract

In today's digital era, the need for fast, accurate, and responsive information systems is increasingly pressing, especially in the higher education sector where prospective students often face obstacles in directly obtaining relevant and reliable academic information. To address this challenge, this research focuses on the design and development of an academic service chatbot by implementing the Retrieval-Augmented Generation (RAG) method at Catur Insan Cendekia University. The RAG approach combines information retrieval capabilities from various documents (retrieval) with the generative intelligence of language models, thus being able to produce contextual, personalized, and data-driven answers. The chatbot system was developed using Python, LangChain, FAISS, and the GPT model as the core of natural language processing. Performance evaluation was conducted using the ROUGE metric, which showed quite good results with a ROUGE-1 value of 0.50 and a ROUGE-L of 0.48. These findings prove that the system is capable of providing relevant and high-quality responses in helping answer prospective students' academic questions. With these advantages, this chatbot is expected to be an innovative solution to improve the quality of academic information services at UCIC, as it can present data quickly, accurately, interactively, and automatically. Furthermore, the implementation of this artificial intelligence-based technology aligns with digital transformation efforts in higher education, supporting the efficiency of academic services and strengthening the institution's image as a modern campus that adapts to developments in information technology.

Abstract

Stable temperature regulation is essential in various industries to maintain product quality and energy efficiency. This study analyzed the water temperature regulation system using PID control through MATLAB simulation and the actual implementation using Thermocontrol and PT100 sensors. In the simulation, the PID control parameters used were Kp = 3.0, Ki = 240, and Kd = 60, while the tuning results in the actual implementation were Kp = 3.0, Ki = 0.5, and Kd = 1.2. The simulation results showed that the system could reach the setpoint faster (±330 seconds), but with a high overshoot (±20.8°C). In contrast, the actual implementation shows more stable performance, with a much lower overshoot (±0.8°C) and a time to the setpoint of about ±345 seconds. These differences in performance can be influenced by environmental factors and the physical characteristics of real systems that are not fully reflected in the simulation. Although the simulation provides faster results, the actual implementation is more adaptive to changing conditions and better able to maintain temperature stability. This research can provide important insights into the development of more effective and reliable temperature control systems for industrial applications, as well as demonstrate the importance of proper tuning in PID control systems to achieve optimal performance.

Abstract

This study aims to determine the effect of varying hybrid composite volume fractions of luffa (Luffa cylindrica) fiber and fiberglass on the tensile strength of the material. The composite matrix used was polyester resin, while the reinforcements consisted of luffa fibers treated with 5% KOH alkaline solution to improve adhesion with the matrix, and fiberglass as an additional strengthening material. The composition variations applied in this research were 90%:5%:5%, 85%:7.5%:7.5%, and 80%:10%:10% (polyester resin : luffa fiber : fiberglass). The fabrication process was carried out using the hand lay-up method, which is widely used for producing layered composites, followed by tensile testing according to standard mechanical testing procedures to evaluate tensile strength and elongation. The results showed that the addition of luffa fiber and fiberglass fractions had a significant influence on the mechanical properties of the composites. The 80%:10%:10% variation demonstrated the highest tensile strength value of 13.65 MPa and the highest elongation of 0.0105%, indicating better mechanical performance compared to other variations. These findings confirm that the hybridization of natural luffa fiber and synthetic fiberglass can work synergistically to improve the tensile strength of the composite. However, higher fiber fractions should be considered carefully, as they may affect the homogeneity of the mixture and the quality of interfacial bonding. Further research is recommended to optimize volume fractions, enhance fiber surface treatments, and evaluate additional mechanical properties such as impact strength and hardness, in order to explore the potential of hybrid composites as eco-friendly materials with promising mechanical performance.

Abstract

The land of the former Pit B limestone mine of PT Semen Baturaja has failed to plant and grow dwarf plants at several locations due to low nutrient content, such as Nitrogen, Phosphorus, Potassium, Soil PH, C-Organic, and cation exchange capacity (KTK). This condition causes the plant not to grow optimally. This study aims to determine the effect of the application of Rhizobium sp bacteria on the growth of Sengon plants (Falcataria moluccana) using polybag media on the land. The method used was an experiment with the treatment of giving Rhizobium sp in various doses. The results of the study showed that the administration of Rhizobium sp had a real effect on increasing the growth of sengon plants. Based on laboratory observations and analysis, there is a change in soil pH from slightly alkaline to neutral after treatment. The C-Organic content increased from medium to very high, while the Nitrogen content rose from medium to high. The elements of Phosphorus, Potassium, and KTK have also increased significantly and are classified as very high. The best treatment is obtained at a dose of 30 grams of Rhizobium sp, which gives optimal results on an increase in plant height and root length. These findings suggest that the application of Rhizobium sp can be an effective biotechnology alternative in post-mining land rehabilitation, particularly in improving soil fertility and forestry crop productivity. This research contributes to environmental management and the use of microorganisms in the restoration of degraded ecosystems.

Abstract

Fear of crime is closely linked to various factors such as education, income, race, age, and especially gender. Many studies have shown that women tend to experience higher levels of anxiety than men, thus limiting their participation in utilizing urban outdoor spaces. This condition emphasizes the need for crime prevention efforts to be integrated into urban planning, emphasizing the fulfillment of a sense of security not only physically but also psychologically. If the city fails to provide an adequate sense of security, it will lead to increased anxiety, discomfort, and ultimately limit community involvement in the use of public spaces. This study aims to identify design factors that influence women's sense of security and psychological safety in downtown areas. The research paradigm used is post-positivism with a quantitative approach, reinforced by walkthrough analysis techniques to produce more accurate findings. The results show that control factors are the most dominant aspect in influencing women's psychological security and safety, while sub-factors such as lighting, diversity of activities, availability of open spaces, and road conditions have also been shown to play a significant role in reducing women's anxiety when accessing public spaces. Thus, this study emphasizes the importance of city center design that is not only oriented towards physical function alone, but also pays attention to psychological aspects in order to create a safe, inclusive, and gender-friendly urban environment so that women can feel more protected and free to participate in urban life.

Abstract

Preventing accidents during drilling and well service operations is a constant and primary concern for every company or contractor operating in the upstream business. Accident analyses often identify a number of causative factors and/or anomalies, where equipment-related items play a significant role. This article concentrates on the rig inspection process as a consistent method for detecting equipment-related anomalies before operations commence. These inspections allow necessary repairs to be made in a timely manner, thereby limiting the occurrence of accidents after the rig becomes operational. When thorough and systematic rig inspections are performed, the percentage of accidents where equipment failure is the primary cause remains very low. However, the factor of equipment condition contributing to accidents still persists in a significant number of cases. Drilling rig mast inspection is a crucial component in maintaining the safety and efficiency of drilling operations. This inspection process aims to detect structural anomalies and equipment conditions that could affect rig performance. In this study, we analyze the inspection methods applied to rig masts, including visual inspection, non-destructive testing, and condition monitoring. The results of these inspections are expected to identify potential risks and enable necessary repairs before operations begin. Through the implementation of systematic and standardized inspection procedures, companies can reduce the likelihood of accidents and equipment failures, thereby enhancing workplace safety. This study also discusses the importance of training for inspection personnel to ensure they possess the necessary knowledge and skills to detect potential problems that may arise. Thus, drilling rig mast inspection contributes not only to safety but also to overall operational efficiency.

Abstract

This research aims to develop and evaluate the performance of a steam plant prototype designed as an alternative source of electrical energy to support the Vessel to Grid (V2G) concept. Utilization of backup energy on ships is becoming important as electricity demand increases and demands for a more sustainable electrical system. This system relies on ESP32 microcontroller technology as a control center that functions to monitor and control several key parameters, including steam pressure, combustion temperature, boiler water level, and the generated electrical voltage. The research method used is an experiment with a static and dynamic testing approach. Static testing is carried out to measure the performance of main components such as the boiler, turbine, and generator separately, while dynamic testing focuses on evaluating the overall system by involving the integration of sensors and supporting actuators. The test data is then analyzed quantitatively to determine the system's response to variations in steam pressure, temperature, and other operational conditions. The results show that the steam produced by the boiler is able to rotate the turbine, thereby driving the generator to produce electricity. The maximum voltage achieved is 25.7 volts at a steam pressure of 50 psi. The highest energy conversion efficiency was recorded at 4%, while the lowest efficiency was 0.9%. These findings demonstrate that, despite its relatively low efficiency, the prototype can function as an alternative energy source and emergency backup solution. Thus, this research provides an initial contribution to supporting the implementation of the V2G concept through the development of a small-scale steam plant-based energy conversion system.

Abstract

Abandoned mining sites often experience a decline in soil fertility, which impacts soil quality and agricultural sustainability. This study aims to explore the potential of Pseudomonas fluorescens in rehabilitating limestone mining lands and enhancing the growth of Sengon (Falcataria moluccana) trees grown in polybag media. Sengon was selected as a pioneer species due to its resilience in degraded soils and its ability to improve soil structure. This study used an experimental design involving eight different treatments, which included the application of manure and varying concentrations of Pseudomonas fluorescens. Evaluations were conducted on the 25th and 50th days by measuring plant growth parameters such as plant height, root length, and key soil chemical properties, including pH, organic carbon, total nitrogen, total phosphorus, total potassium, and cation exchange capacity (CEC). The results showed that the application of 15 mL of Pseudomonas fluorescens on day 50 resulted in optimal plant growth, as indicated by an increase in plant height, root length, and soil quality improvement. The application of Pseudomonas fluorescens also enhanced soil pH, organic carbon, total nitrogen, and cation exchange capacity, all of which contributed to the improvement of soil fertility in the limestone mining land. This study provides evidence that Pseudomonas fluorescens can play a role in the rehabilitation of abandoned mining lands and improve the growth of Sengon trees, contributing to the recovery of degraded ecosystems.
