Authors: Alfiani Devi , Lestaluhu Said
Published: January 2025

Abstrak: Penelitian ini bertujuan untuk mengetahui dan mempelajari lebih lanjut mengenai digitalisasi dalam penerapan e-tilang di Kota Ambon. Penelitian ini menggunakan metode penilitan kualitatif, dengan data primer dan sekunder yang dikumpulkan melalui observasi, wawancara, dokumentasi, dan kajian pustaka serta menggunakan sejumlah informan kunci yang dianggap terlibat langsung dalam aktifitas e-tilang di kota Ambon. Hasil penelitian ini menunjukan bahwa pemanfaatakan teknologi digitaliasi dalam penerapan e-tilang di Kota Ambon, terdapat beberapa komponen didalamnya, diantaranya kamera ETLE yang bertindak sebagai sumber informasi, bertugas untuk mengawasi dan menangkap para pelanggar lalu lintas secara terus-menerus selama 24 jam melalui identifitaksi nomor polisi kendaraan. Selanjutnya informasi pelanggar akan di trasmisikan kepada petugas ditlantas untuk memvalidasi informasi yang diterima. Kemudian di cetak menjadi surat konfirmasi e-tilang dan dikirim melalui kantor pos sebagai media penyampaian informasi yang akan disampaikan kepada para pelanggar. Namun penggunaan teknologi digitalisasi dalam penerapan e-tilang, pada kenyataannya masih belum menerima respon serius dari masyarakat. Hal ini dikarenakan masih banyak hal yang perlu evaluasi dan ditingkatkan kembali karena menjadi noise (hambatan), seperti : titik lokasi dan jumblah kamera ETLE yang terbatas, sistem yang digunakan, pengawasan intensif dan anggaran operasional yang minim tidak bisa mengcover jumblah pelanggar setiap harinya serta kurangnya kesadaran masyarakat akan penerapan e-tilang. Dimana hasil dari penelitian ini dapat dikatakan bahwa penerapan e-tilang di Kota Ambon kurang efektif. Bersadarkan hasil observasi dan wawancara yang dilakukan dengan pihak Direktorat Lalu Lintas Polda Maluku (Ditlantas), pelanggar e-tilang dan masyarakat untuk mengetahui bagaimana implementasi, tingkat pengetahuan dan kesadaran masyarakat terhadap penerapan e-tilang di Kota Ambon. Dengan tujuan untuk mengetahui dan dapat menjadi bahan evaluasi penerapan e-tilang agar masyarakat Kota Ambon dapat memahami dan mematuhi peraturan lalu lintas demi keselamatan berkendara para pengguna jalan.

This study aims to compare the methods of testing the moisture reduction of cocoa beans with the high-temperature and low-temperature oven methods. The method used in this study was a comparative test between three cocoa clones and two moisture content test methods, namely using a low-temperature oven and a high-temperature oven. This research is experimental using a completely randomized design (CRD). The results of the cocoa moisture content test showed that each treatment of K2O2 and K1O2 was not significantly different from the results of the moisture content of cocoa beans. In contrast, the comparison of each treatment of K2O2, K1O2 and K3O2 was significantly different from the results of the moisture content of cocoa. Furthermore, for the K3O2 treatment compared to each of the K1O1, K2O1, and K3O1 treatments, the results of cocoa content were significantly different. For each treatment, K1O1, K2O1, and K3O1 did not differ significantly in the results of the moisture content of cocoa. High temperatures and low temperatures in Table 2 show that the K1O1 yield is 8.03%, significantly different from the K1O2 cocoa bean moisture content, which is 9.59%. and K3O1 7.57% with K3O2 which is 8.85 Testing the moisture content of cocoa seeds using the high-temperature oven method for 2 hours was significantly different from the low-temperature oven method for 17 hours. The proper method for testing the moisture content of cocoa beans is high temperature for 2 hours.

The results of fatigue and fractographic studies of specimens of additive manufactured 316L stainless steel are presented. The features of nucleation and mechanisms of fatigue crack growth at the stage of its stable and accelerated growth have been studied, and critical crack lengths on fracture surfaces corresponding to these stages have been estimated. The critical stress amplitude σ* has been established. Upon reaching σ* a transition from multi-origin fracture of the specimen at high amplitudes to predominantly single-origin fracture at low amplitudes accompanied by a change in the fracture mechanism, fracture surface profiles and damage to the lateral surface of the specimens is observed. It is shown that the decrease in fatigue characteristics is associated with early crack initiation on technological defects formed during production.

Based on the analysis of diffusion processes, a theoretical justification is presented for the possibility of synthesizing silicon carbide from a mixture of carbon black and silicon powders at a temperature below 1600 °C. Experimental confirmation of this possibility was obtained during solid-phase synthesis in a vacuum for 8 hours at a temperature of 1400 °C. With a shorter sintering time, an incomplete reaction of silicon carbide synthesis is noted. The synthesis conditions were studied and the parameters were identified at which the initial powder mixture was completely converted into silicon carbide. Electron microscopy and X-ray phase analysis were used to study the microstructure and phase composition of the materials. The finished compacts have a uniform submicron microstructure with a grain size of less than 1 μm.

Thermal conductivity of carbon fibers used as reinforcements is a very important property that defines effectiveness of composite materials for heat insulation and heatsink applications. Nevertheless, no thermal conductivity data are available for many commercial carbon fibers from both the manufacturers’ datasheets and academic sources; this fact may be linked with measurement problems for yarn- and filament-like specimens. In the present study we assess the possibility to evaluate thermal conductivity of carbon fibers with known Young’s moduli based on empirical correlations established for commercial carbon fiber types. Empirical equations correlating Young’s moduli and thermal conductivities of carbon fibers have been established, calculated and experimental values of thermal conductivities for several domestic polyacrylonitrile-based carbon fibers have been compared. For rayon-based fibers published data are scarce, so calculated values were compared with expected ranges. Possible explanations of the observed correlations are proposed considering structure-dependent properties of the materials under study. Proposed equations are intended for use in thermal conductivity prediction of novel carbon fibers as well as heat transfer modelling in carbon-fiber reinforced composite materials.

This study evaluated the ageing effects after enduring a cyclic torsional test on electrically high thermal Graphene Nanoplates (GNP)/Ag conductive ink. The Graphene Nanoplates (GNP) hybrid formulation contained silver flake (Ag) as an additional filler, 1-butanol and terpineol as organic solvents for the paste, and ethanol as a chemical solvent for the powder GNP hybrid synthesis. An in-house torsional cyclic test rig actedas an experimental apparatus to hold cyclic torsional tests in measuring the resistivity value of GNP/Ag conductive ink. The sample endured 1000, 2000, and 4000 cycles of repetitive cyclic torsion. The sample was left unattended in a controlled environment for ageing process observation in 15 weeks. Resistivity values for both tests were obtained by using a two-point probe multimeter. Data from the cyclic torsional test showed an increase in average resistivity as the cycles prolonged until 4000 cycles. The outcome of these experiments proved that Graphene Nanoplates (GNP)/Ag conductive ink manages to withstand material deformation and remain electrically stable after experiencing cyclic twisting and the ageing process. The recorded SEM images of the ink layer microstructure surface showed a direct correlation with the obtained sheet resistivity data. The samples that produced high sheet resistivity showed the presence of microcracks and defects on the ink layer The results of this study imply that repeated twisting in a thin film may lead to different mechanical and material modifications, thereby influencing its electrical and mechanical properties, which is vital to developing more reliable and stable stretchable electronics. Additional research on various twisting angles and ink compositions is recommended to have a more profound understanding of the characteristics and features of GNP/Ag conductive ink.

This paper explores the complex relationship between acoustic streaming and vibration in thermoacoustic systems, enhancing the comprehension of these interconnected phenomena in the realm of energy conversion and heat transfer. Thermoacoustic devices are becoming more important for sustainable energy uses. The dynamic interaction between acoustic streaming and vibration is a crucial yet unexplored aspect of the performance of thermoacoustic devices. This research is driven by the necessity of filling current knowledge deficiencies and acknowledging the importance of these factors in the performance of thermoacoustic systems. This study intends to enhance the understanding about acoustic streaming and vibration through the utilisation of numerical simulations and experimental studies. In this paper, a two-dimensional (2D) computational fluid dynamics (CFD) model of standing wave thermoacoustic flow conditions was solved using the SST k-ꞷ turbulence model in ANSYS Fluent to simulate the streaming induced by the vibrational responses within a standing wave thermoacoustic test rig. This numerical prediction is then validated using experimental results from a similar operating condition with a single resonance frequency of 23.6 Hz. Three drive ratios were examined. Disparity between velocity amplitude from CFD simulation and experimental data was observed particularly at the highest drive ratio. As the drive ratio increases, so does the amplitude of the velocity. It was discovered that the model that includes vibration brings the difference in results between the model and the experiment to be smaller and it replicates the closest scenario to the actual condition.
Relationship between nutrition and chronic low back pain. Review
Authors: Gubska O. Y. , Ovdiia M. O. , Kurets O. O.
Published: January 2025

Low back pain is a common and complex condition that significantly affects people’s daily functioning, ability to work, quality of life and places a significant burden on the healthcare system. Chronic low back pain is pain that persists for more than 12 weeks and is caused by mechanical, psychological and social factors. The main risk factors for chronic low back pain include a sedentary lifestyle, overweight and obesity, high stress levels, smoking, sleep disturbances, concomitant chronic diseases and poor diet. The World Health Organisation emphasises the importance of nutrition as part of a healthy lifestyle and an important preventive aspect of chronic non-communicable diseases. The relationship between nutrition and health is complex and multicomponent, involving direct and indirect mechanisms of influence. In recent years, a significant number of publications have appeared in the literature on the relationship between nutrition and low back pain. The purpose of this review was to analyse and systematise the knowledge on the mechanisms of the relationship between nutrition and chronic low back pain. An unhealthy diet is the main cause of underweight or overweight, which has an indirect effect on the development of chronic low back pain. Diets with anti-inflammatory properties can reduce inflammation, normalize weight, and have a positive effect on the course of chronic low back pain. The review found that the main mechanisms of interaction between nutrition and chronic pain are the pro-inflammatory properties of foods, underweight, overweight and obesity, and macro and micronutrient deficiencies. There is a need to develop nutritional strategies for patients with chronic low back pain as one of the key areas of a multidisciplinary approach to solving this problem.

This study objective is to analyze the effectiveness of using the technology of tail suspension of cars as a way to increase the reliability and comfort of movement in railway transport. To achieve this goal, the following task was defined: identification and analysis of internal defects that are the causes of product rejection, and the subsequent development of recommendations for their elimination. The main research method is the analysis of current operating procedure of manufacturing parts, the study of materials and methods of their processing used to strengthen tails.
The priority is to identify the key factors contributing to increasing the durability of the tail assembly through the use of reinforcing technology.
Both theoretical analysis of existing scientific papers on this topic and practical experiments on stress tests are used as research methods.
The novelty of the work is in offering a more environmentally friendly product processing technology, as well as confirming the possibility of replacing the tail material with a more cost-effective one.
It is worth noting that the issue of ensuring the quality of truck tails of subway cars, the ecological purity of the heat treatment process, and cost reduction is being solved through a new heat treatment technology – quenching with a fast-moving stream of water and replacing 40X alloy steel with 35 carbon steel without reducing operational properties.
As a result, the proposed measures contribute to improving the manufacturing quality of tail assemblies and reducing the percentage of their rejection at the production testing stage.

Published: January 2025

This study explores the clay potter community's socio-economic dynamics and evolving livelihood patterns in Pirganj, Rangpur, Bangladesh. Despite their historical significance and cultural heritage, potters in this region confront numerous challenges threatening their traditional craft and economic stability. Employing a mixed-methods approach, the research combines quantitative surveys, semi-structured interviews, focus group discussions, and case studies to analyze the community's current state comprehensively. Findings indicate notable improvements in human capital—health, nutrition, and education—which have fostered social mobility and economic resilience. However, these advancements have also led to declining traditional pottery practices as younger generations pursue alternative careers. Physical and natural capital assessments reveal inadequate housing, poor transportation infrastructure, limited sanitation facilities, and environmental challenges like deforestation and natural calamities disrupting agriculture and pottery production. Key vulnerabilities identified include the scarcity and rising costs of raw materials, technological innovations favoring mass-produced alternatives, limited government support, lack of wholesale buyers, and media influence promoting modern lifestyles. These factors collectively undermine the pottery sector's sustainability. The study recommends multifaceted strategies, including specialized training programs, financial assistance during crises, establishing reliable market linkages, enhancing support from government and NGOs, and raising public awareness of traditional clay products' cultural and economic value. Additionally, promoting youth engagement in pottery through incentives and educational initiatives is emphasized to ensure the craft's continuity. Conclusively, preserving the clay potter community in Pirganj is crucial for maintaining Bangladesh's rich cultural heritage and fostering economic diversity. The study highlights the need for collaborative efforts between governmental bodies, non-governmental organizations, and the community to implement sustainable solutions that support traditional artisans' cultural and economic vitality.
Changes in Fluctuation Waves in Coherent Airflow Structures with Input Perturbation
Authors: Marzouk Osama Ahmed
Published: January 2025

We predict the development and propagation of the fluctuations in a perturbed ideally-expanded air jet. A non-propagating harmonic perturbation in the density, axial velocity, and pressure is introduced at the inflow with different frequencies to produce coherent structures in the airflow, which are synchronized with the applied frequency. Then, the fluctuations and acoustic fields are predicted for each frequency by integrating the axisymmetric linearized Euler equations. We investigate the effect of the perturbation frequency on different characteristics of the pressure and velocity waves. The perturbation frequency can be used to alter the propagation pattern and intensity of the waves and mitigate the noise levels at certain zones.
Accurate Prediction of Noise Generation and Propagation
Authors: Marzouk Osama Ahmed
Published: January 2025

Jet engines are characterized by high-speed free jets. The fact that Federal Aviation Regulations regarding noise levels retard the progress in high speed civil transport planes raises the interest in accurate methods to predict and reduce jet noise. Here, the perturbed flow field of a supersonic jet is solved using an advantageous numerical technique, and the associated noise filed is predicted. Comparisons with experimental results show that this technique is efficient for this kind of problems as it gives accurate results without requiring a lot of computational power. Due to the nature of the problem, special attention needs to be given to the numerical method as well as the boundary treatments. We observed radial acoustic profiles at different axial distances, where peak intensity is encountered before the decay.
Radio frequency and microwave photonic based functions using Kerr microcombs
Authors: Moss David
Published: January 2025

We demonstrate advanced transversal radio frequency (RF) and microwave functions based on a Kerr optical comb source generated by an integrated micro-ring resonator. We achieve extremely high performance for an optical true time delay aimed at tunable phased array antenna applications, as well as reconfigurable microwave photonic filters. Our results agree well with theory. The true time delay we show would yield a phased array antenna with features that include high angular resolution and a wide range of beam steering angles, while the microwave photonic filters feature improved Q factors, wideband tunability, and highly reconfigurable filtering shapes. These results show that our approach is a competitive solution to implementing reconfigurable, high performance and potentially low cost RF and microwave signal processing functions for numerous applications including radar and communication systems.

Published: January 2025

Hybrid modeling integrates the strengths of mechanistic and data-driven approaches to overcome their respective limitations, offering a promising framework for predicting and understanding complex engineered microbial processes. However, its application in this field remains underdeveloped. To assess the current state of hybrid modeling, an extensive literature review was conducted and yielded only 34 relevant articles over the past 30 years, with 26 hybrid models in 24 articles published in the last five years. This review systematically examined key processes in hybrid modeling, including data collection, data processing, model construction, and model validation, and identified critical challenges that were often not properly conducted. Issues such as hyperparameter tuning and data leakage were particularly overlooked in the reviewed literature, which could compromise model performance and reliability. To address these challenges, a standard protocol is proposed to mitigate common pitfalls and enhance model robustness. This review provides a comprehensive analysis and practical recommendations, laying the groundwork for future studies to advance hybrid modeling of engineered microbial processes.
