Three radiation detection tools were employed to assess natural radiation levels in Mamuju Regency, West Sulawesi, Indonesia. These tools comprised the NaI(Tl) Scintillator, the Geiger Muller Counter (GMC), and the Electronic Personal Dosimeter (EPD). The NaI(Tl) Scintillator and GMC measured ambient dose equivalent (H*(10)), while the EPD exclusively gauged personal dose equivalent (Hp(10)). A total of 75 measuring points were designated for assessment. Results from H*(10) measurements indicated that the GMC recorded an average H*(10) 41% higher than that of the NaI(Tl) Scintillator, with specific rates of 0.769 µSv/h and 0.457 µSv/h, respectively. Both instruments exhibited proficiency in detecting elevated levels of radiation. Discrepancies in the outcomes were attributed to differences in detector type and efficiency. The GMC, equipped with an energy-compensated detector, demonstrated enhanced efficiency compared to the NaI(Tl) Scintillator, particularly when subjected to high energy flux radiation. Anomalies emerged in the Hp(10) measurements, which surpassed the H*(10) measurements. This difference is due to the EPD's use of a conventional GM detector, which is capable of detecting gamma, beta, and X-ray radiation. © 2025 Published by IRCS-ITB.

The cement industry in Indonesia, heavily relies on coal, contributing significantly to greenhouse gas (GHG) emissions. Simultaneously, Java Island generates over 23 million tons of municipal solid waste (MSW) annually, with limited utilization for energy recovery. This study evaluates the feasibility of substituting coal with refuse-derived fuel (RDF) from MSW in Java's cement industry, focusing on environmental, economic, and technical aspects. Scenario analyses indicate that substituting 10%, 20%, and 30% of thermal energy with RDF could divert up to 8.7 million tons of MSW from landfills annually, reducing GHG emissions by up to 2.77 million Gg CO₂-eq. These reductions align with Indonesia's environmental policies and global climate commitments under the Paris Agreement. The economic assessment demonstrates the viability of RDF, with potential annual cost savings of up to $421 million. Beyond addressing coal dependency, RDF adoption supports circular economy practices, reduces landfill reliance, and mitigates environmental pollution. However, challenges such as infrastructure gaps and regulatory barriers require attention. This study provides actionable insights to guide policy formulation, foster industry investment, and facilitate the implementation of RDF-based energy solutions. By bridging waste management and sustainable energy practices, the findings contribute to Indonesia's renewable energy goals, emphasizing the practical applications of RDF for a more sustainable future in industrial operations. © 2025 The Authors

We employed three radiation detection devices: NaI(Tl) Scintillator, Geiger Muller Counter (GMC), and Electronic Personal Dosimeter (EPD) in highest natural background radiastion area in Inonesia. Direct measurements conducted with these three devices were validated by measuring radionuclide activities in the soil using HPGe Gamma Spectrometry. Among these three devices, two of them measure ambient dose equivalent (H*(10)), while one measures personal dose equivalent (Hp(10)). The measurement results indicating average H*(10) values of 0.457 µSv/h from NaI(Tl) Scintillator data and 0.769 µSv/h from GMC data, while the average Hp(10) value measured by EPD shows 0.986 µSv/h. The measurement of H*(10) by GMC is 45% higher than that of the NaI(Tl) Scintillator. This difference is also evident from the degenerate 2D map, where GMC data highlights locations of high flux gamma ray anomalies more clearly. This suggests that both devices exhibit different efficiencies under high gamma radiation exposure, with GMC showing better efficiency. However, under conditions of high radiation exposure, phenomena such as saturation may affect the performance of the device. The difference in measurement results does not indicate that one device is superior to the other;the naturally high radiation exposure conditions in the research environment affect the performance of both devices. Meanwhile, in the measurement of Hp(10) by EPD, it was found that the Hp(10) readings are higher than H*(10), which should not happen considering Hp(10) depends on the incident angle of radiation. The EPD detector type allows for the detection of radiation at low energies, but if it is not calibrated at this energy level, it might cause overreading when lower energy radiation, such as X-rays, is detected. Dead time and saturation may occur in environments with high background radiation, causing the detector readings to be less than ideal. © 2024, The Authors. All rights reserved.

Naval Engineers Journal 1967年第6期79卷 961-971页

作者： AZIZ, ABDUL THE AUTHOR was born in East Pakistan on January 31 1932 received the Bachelor of Science degree in Mechanical Engineering from the Dacca University in Pakistan in 1952 and the Master of Science degree in Mechanical Engineering from the Michigan State University in 1953. He did further graduate work at MIT Columbia and Johns Hopkins Universities and is now a candidate for the doctoral degree at the University of Maryland. He joined the Department of Navy in March 1966 with the Naval Ship Research and Development Center Annapolis Division where he worked on the MESA (Machinery Effectiveness Systems Analysis) Program sponsored by the Navy Ship Systems Command. The present paper is largely based on a 138-page report entitled “Systems Effectiveness in the United States Navy” on the works of the MESA Program. Currently he is assigned to the Naval Research Laboratory to provide inhouse engineering support in the development and analysis of systems and their components for the conduct of fundamental research in Astronomy and Astrophysics by the Laboratory. Prior to joining the Department of Navy he worked for General Electric Cdmpany in the analysis and development of large steam turbine components and for Burns & Roe Corporation in systems design and analysis for power plants both fossil powered and nuclear. With Burns & Roe he participated in the systems effectiveness analysis of the Army PM-3A nuclear power plant in the Antarctica. He received the United States citizenship in January 1966 is a member of the ASME and the U.S. Naval Institute.

A genomic database of all Earth’s eukaryotic species could contribute to many scientific discoveries;however, only a tiny fraction of species have genomic information available. In 2018, scientists across the world united under the Earth BioGenome Project (EBP), aiming to produce a database of highquality reference genomes containing all ~1.5 million recognized eukaryotic species. As the European node of the EBP, the European Reference Genome Atlas (ERGA) sought to implement a new decentralised, equitable and inclusive model for producing reference genomes. For this, ERGA launched a Pilot Project establishing the first distributed reference genome production infrastructure and testing it on 98 eukaryotic species from 33 European countries. Here we outline the infrastructure and explore its effectiveness for scaling high-quality reference genome production, whilst considering equity and inclusion. The outcomes and lessons learned provide a solid foundation for ERGA while offering key learnings to other transnational, national genomic resource projects and the EBP. © The Author(s) 2024, corrected publication 2024.
