Lung disease, especially Tuberculosis (TBC), placed the highest death rate in Indonesia. Tuberculosis (TB) in Indonesia is ranked second after India. Therefore, it is important to reduce or early detection of the lung disease, to prevent this disease and speed up handling. The system can recognize the disease lung identification, and the system applied as standalone system. In this work, the Convolutional Neural Network (CNN) approach for identifying diseases lung identification is proposed. The Mel Frequency Cepstral Coefficient (MFCC) applied to process the stethoscope sounds which will used as input to the CNN. The performance of the proposed system has been investigated and resulted. The accuracy of 99% and 98%, for training and testing accuracy respectively. Furthermore, the system accurately detects lung diseases identification. © 2024 IEEE.

The exploration of biomass fuels is crucial for enhancing the economic value of solid waste from palm oil and mitigating the environmental impact of greenhouse gases emitted by power plants. This study conducted a numerical analysis on a pulverized coal (PC) boiler with co-firing at various burner positions. The numerical simulation results indicate that co-firing with empty fruit bunch (EFB) can enhance the ignition characteristics of Low Rank Coal (LRC). shown in the FEGT area an average increase in temperature of 0.2-0.45%. However, it should be noted that this temperature value is still within safe limits because it does not cause overheating of the heater. Furthermore, the formation of unburned particles can be reduced through the distribution of CO2. Additionally, the co-firing case 2 exhibits low NOx emissions, with a decrease rate of 24.6% when burner B is set at a condition of 1,63E-07. This condition is considered the most ideal as it is also accompanied by a significant reduction in SO2 emissions, ranging from 21.82% to 24.7%. © 2024 IEEE.

Business process management has become a critical focus for many manufacturing industries. The function of business process management is to achieve organizational goals through the improvement, management, and control of business processes. A crucial step for companies in visualizing, analyzing, and optimizing workflows is business process modeling. Business Process Model and Notation (BPMN) is a tool widely used to visualize business process flows. This study employs a qualitative approach, using interviews conducted with seven small and medium-sized industries (SMIs). Important findings identified in SMI, in the recording process, both upstream and downstream processes, are still carried out manually, this is related to the potential for implementing enterprise resource planning (ERP). Regarding the processes on the production floor, in addition to paying little attention to implementing record-keeping systems, SMIs also tend to neglect forecasting methods, warehouse management, and the use of material handling. © 2024 IEEE.

Small and Medium-Scale Industries (SMIs) play a significantly important role in the nation's economy. The adoption of current technology is necessary for SMIs to remain agile amidst industrial changes or challenges. However, they often face limitations in utilizing technology, particularly information technology, in their business processes. One popular integrated information system is the Enterprise Resource Planning (ERP) system, which connects various business units within an organization into a single integrated system. The implementation of ERP systems in small and medium-scale industries is necessary to enhance the effectiveness and efficiency of their business processes. In this paper, we conduct a systematic review of the literature discussing the adoption of open-source ERP systems in SMIs. The conclusion drawn is that ERP implementation in SMIs occurs across various sectors, including services, trading, and manufacturing. Developing open-source ERP systems poses substantial challenges for SMIs. This literature review investigates trends in ERP implementation for SMIs, highlighting current research directions and uncovering new insights and opportunities that can inform future studies. © 2024 IEEE.

A SOFC triple combined cycle power generation, consisting of a solid oxide fuel cell and gas turbine combined cycle is revealed to give efficiency improvement while reducing the amount of emissions in power generation. It comes from the fact that the exhaust heat generated from a cycle is further utilized for power generation in the next cycle. Studies concerning its designs and optimizations have been investigated, including the characteristics of the system. This study investigates the load following the response of a hydrogen-fueled triple combined cycle, where both the fuel cell and gas steam turbine run on hydrogen fuel. The hydrogen fuel consumed will be provided by a hydrogen generation system of a proton exchange membrane electrolyzer (PEMEC). The generated hydrogen is then stored in a hydrogen tank until further use. The Hydrogen generation triple combined cycle system is interconnected with a substation of renewable energy. Surplus electricity from renewables will be directed to power the electrolyzer. © 2023 IEEE.

Efficient and reliable parcel delivery services are always desired in different sectors such as hospitals, offices, industries and households. One promising solution to meet, this need is the application of Autonomous Mobile Robots (AMRs) capable of navigating complex indoor environments to deliver packages and goods. Generally, AMRs are used for the last-mile delivery of parcels. The end users of such robots have different skill sets, and the robot must have a simple user interface to ensure easy usability. This paper presents an AMR with an intuitive Graphic User Interface (GUI) and aesthetic design. It is enough for the end user to define the goal locations on the resulting map shown on the robot screen. The AMR will autonomously navigate to the given goal location. Besides, the effectiveness of sensor fusion and a comparative study of various combinations of sensor fusion are also described in this paper. In addition, the application of LiDAR odometry and its performance is also analyzed in this paper. The primary objective of this study is to identify an approach that improves the AMR’s tracking accuracy and makes it suitable for dynamic work environments. This paper describes the development of an AMR for last-mile delivery purposes, and its proof of concept is evaluated on the fabricated prototype. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
