Abstract

This study presents a comparative performance evaluation of Fiber Ethernet and copper Ethernet (Cat6) using a controlled testbed to quantify differences in throughput and Quality of Service (QoS). Identical endpoints are connected through a managed switch, and the physical medium is alternated between a fiber link and a Cat6 link. Traffic is generated under TCP and UDP at three utilization levels (10%, 50%, and 90%) and three distance conditions (10 m, 50 m, and 90–100 m for Cat6). The evaluation uses application-level and interface-level measurements, including TCP/UDP throughput, round-trip latency, jitter, packet loss, and reliability counters such as CRC/FCS errors and TCP retransmissions. Results show that both media can achieve near line-rate throughput at short distance and low load, but fiber exhibits consistently lower latency and jitter and near-zero loss across conditions. As utilization increases, Cat6 displays larger variability in delay and a higher tendency toward UDP loss, indicating reduced timing stability under stress. At longer copper runs (90–100 m), the gap widens: Cat6 shows higher jitter and loss and increased error-related counters, while fiber remains stable. These findings suggest that the main advantage of fiber is not only peak capacity but also QoS predictability and link integrity, which are critical for real-time and high-utilization services. The study provides practical guidance for selecting media in campus and building networks where distance, load, and service requirements must be balanced. Future work will include electromagnetic-noise trials, different switch/NIC models, and statistical tests to validate effect sizes across repetitions in diverse building environments

Abstract

Micro, small, and medium enterprises in Purwadana Village still rely mainly on conventional marketing, while limited managerial and digital capabilities constrain consistent use of online channels. This community service program aimed to strengthen human resource competence and digital marketing readiness among 25 village officials and MSME actors. Activities comprised preparation, pre-test, practice-oriented training, mentoring, and post-test. A 0-100 questionnaire assessed short-term understanding of business management and digital marketing. The mean score increased from 54.6 to 80.6, a 47.6% relative increase. Digital marketing understanding rose by 56.2%, while human resource competence rose by 39.8%. During mentoring, participants practiced product photography, promotional captions, social media account management, audience targeting, and marketplace introduction. The results indicate improved short-term knowledge and readiness rather than proven business performance. Follow-up monitoring is required to assess sustained digital use and business outcomes.

Abstract

The Internet of Things (IoT) has emerged as a transformative technology in the healthcare sector, offering significant advantages for improving the efficiency and reliability of medical logistics. This study presents a systematic literature review of recent research (2020–2025) focused on the application of IoT in medical logistics. A total of 200 studies were initially identified, and through a structured selection process using the PRISMA framework, six articles were ultimately included for in-depth analysis.The findings highlight that IoT technologies are widely applied in areas such as cold chain monitoring, inventory tracking, real-time asset management, and integration with blockchain and cloud platforms. These applications improve data accuracy, reduce product spoilage, and enhance traceability. However, challenges such as high implementation costs, system interoperability, and data security risks persist, especially in low-resource settings.This review provides a comprehensive overview of the current state of IoT implementation in medical logistics and offers insights for future research and policy development. The study concludes that a multidisciplinary and collaborative approach is essential to realize the full potential of IoT in creating responsive and secure healthcare supply chains.

Abstract

The pharmaceutical supply chain faces increasing pressure to ensure transparency, safety, and efficiency across global operations. This study presents a systematic literature review (SLR) of global tracking and traceability systems in pharmaceutical logistics, focusing on technological innovations such as RFID, barcoding, and blockchain. A total of six peer-reviewed articles were selected based on inclusion criteria through the PRISMA methodology. The results highlight the growing adoption of traceability systems in developed countries driven by regulatory frameworks such as the DSCSA (USA) and FMD (EU). Technologies such as blockchain show high potential in improving drug authentication and preventing counterfeiting. However, barriers such as high implementation costs, lack of infrastructure, and limited standardization continue to hinder adoption in developing nations. The study concludes that pharmaceutical traceability is a strategic necessity for public health and requires coordinated efforts between governments, industries, and global organizations.

Abstract

This study aims to evaluate the medicine logistics management system at Puskesmas x, Batam City, focusing on three key components: medicine distribution, ordering time and Reorder Point (ROP), and medicine disposal. A qualitative research approach was employed, with data collected through in-depth interviews, observations, and document reviews conducted between March and April 2025. The key informants included the pharmacist-in-charge and pharmacy technicians.The results indicate that medicine distribution follows a structured procedure, applying the First Expired First Out (FEFO) and First In First Out (FIFO) principles to maintain quality and minimize waste. The ROP method is integrated into a computerized system, enabling timely procurement when stock levels reach the minimum threshold. Medicine disposal is conducted according to the Standard Operating Procedure (SOP), with expired medicines identified, documented, and either returned to the Batam City Health Office or destroyed on-site.Although the system largely complies with the Standar Pelayanan Kefarmasian di Puskesmas, challenges remain, including procurement delays due to central warehouse shortages and occasional expired stock. Strengthening coordination with the Health Office, improving demand forecasting, and establishing contingency procurement strategies are recommended to enhance efficiency and ensure uninterrupted medicine availability.

Abstract

Reliable management of medicines and medical supplies is a prerequisite for high-quality pharmacy services. This study evaluates the performance of a Pharmacy Installation against national standards and identifies priority areas for improvement. We employed a descriptive–evaluative design using an assessment instrument aligned with the Directorate General of Pharmaceuticals and Medical Devices, Ministry of Health of the Republic of Indonesia (2017), covering two components: Resources (maximum 60) and Management (maximum 40). The results show a total score of 92.46/100, comprising Resources 56.06/60 and Management 36.40/40, classifying performance as compliant with the standard. Strengths are concentrated in operational processes (receipt, distribution, recording and reporting), while opportunities for improvement relate to data-driven planning, strengthening organisational/structural arrangements, and tightening inventory-control practices. Practical implications include implementing clear control parameters (e.g., reorder point and safety stock) and item-priority classifications (e.g., ABC–VED) to stabilise availability, reduce expiry risk, and improve cost efficiency. The study provides a comprehensive snapshot of compliance and a direction of continuous improvement for pharmacy installations.
