Authors: Ma'rufah Hastini , Nugroho L. Hartanto , Sukirno Sukirno
Published: January 2025

Spodoptera litura Fabricius, an insect pest, is known to be highly detrimental to farmers for having a variety of host plants. The application of synthetic insecticides to eradicate pests has been proven to bring many negative impacts, especially regarding the cases of resistance and the presence of residues that are harmful to the environment. This study aims to study the effectiveness of potential bioactive compounds of Tigarun leaves (Crataeva nurvala Buch. Ham) as the biochemical insecticides of S. litura. Tigarun plant, widely used as traditional medicine, contains the potential bioactive compounds for bioinsecticides. The extraction process was carried out by maceration using methanol and ethyl acetate solvents, which were then identified for compound content through GCMS analysis. The bioassay method was performed using the test parameters of mortality and eating power of S. litura instar II larvae. The crude extracts from the two solvents obtained showed their effectiveness as bioinsecticides against S. litura instar II larvae. The highest efficacy occurred in the ethyl acetate extract using the contact poison method with the lowest LC50 value of 0.11. Both extracts were also able to reduce the appetite and provide sublethal effects on S. litura larvae. GCMS analysis indicated the presence of several compounds as insecticides in both Tigarun leaf extracts such as 1,2,3-Propanetriol (CAS) Glycerol; Tetradecanoic acid (CAS) Myristic acid; 9-Hexadecenoic acid; n-Hexadecanoic acid; oleic acid; Heneicosane; and Neophytadiene and several other compounds. This study recommends Tigarun leaf extract (C. nurvala) ethyl acetate with the contact method as a natural insecticide against S. litura.

Published: January 2025

The growing and relatively large market share of 1,2-pentanediol (1,2-PeD) has attracted attention of researchers to find effective and economically viable catalysts. One type of catalyst that can be used for synthesizing this compound is transition-metal-based catalysts, employed in the hydrogenolysis of furfuryl alcohol (FOL). In this study, the hydrogenolysis of furfuryl alcohol were performed with 2-propanol as the hydrogen source and transition metal salts as the catalysts. The used catalysts include first-row early and late transition metals, i.e., ZrOCl2·8H2O, VOSO4·H2O, FeSO4·7H2O, CuSO4·5H2O, NiCl2, Al(NO3)3·H2O, CoCl2, FeCl3·6H2O, and Zn(NO3)2·6H2O. It was found that ZrOCl2·8H2O, VOSO4·H2O, and FeCl3·6H2O demonstrated superior catalytic activity compared to the other catalysts. Optimal reaction conditions for these three catalysts were achieved at 150 °C for 1 hour, using 2-propanol as the hydrogen source. Under these reaction conditions, the ZrOCl?·8H?O catalyst achieved 95.5% conversion of FOL and 30.3% yield of 1,2-PeD, while the VOSO?·H?O catalyst attained 80.5% conversion of FOL and 36.9% yield of 1,2-PeD. Both results were obtained with a low catalyst concentration of 0.6 mmol%. Meanwhile, the FeCl3·6H2O catalyst converted 94.9% of FOL and yielded 30.9% of 1,2-PeD, using a lower catalyst concentration of 0.4 mmol%. Kinetic studies suggested that the reactions likely follow pseudo-first-order kinetics with experimental activation energies (Ea) of 65 kJ/mol, 55 kJ/mol, and 37 kJ/mol for ZrOCl?·8H?O, VOSO?·H?O, and FeCl?·6H?O catalysts, respectively. These findings highlight the potential of transition-metal-based catalysts in achieving high efficiency with low loading, emphasizing their suitability for industrial applications.
GSM Less Communication Over Long-Range Using LoRa (SX1278) Module
Authors: Gupta K. Govardhani
Published: January 2025

Communication is the key to establishing a connection between devices. The ability of devices to communicate with
each other and provide required output according to user requirements is most important in today’s technology field. The most
common communication is Zigbee, Wi-Fi, and others are short-range, and GSM is required. This leads to difficulties in
deploying IoT solutions in areas without cellular (GPRS, EDGE,3G, LTE/4G) coverage and gross reduction in the battery life of
devices. Thus, to provide better connection in all areas, we need low power, long range, and security to deploy. This is where
LoRa comes in. LoRa (Long Range) is a wireless communication technology combining ultra-low power consumption with an
effective long range. It ranges between 13-15 km which indicates that a single LoRa gateway can provide the entire coverage of
the city, and with a couple of it, a whole country can be covered. This paper aims to provide you with the necessary knowledge to
transmit messages across vast distances by utilizing Arduino boards, a duo of SX1278 LoRa Transceiver modules, a pair of
HC05 or HC06 Bluetooth modules, and a pair of OLED screens.

Hundreds of faces are arranged in a strict order.
Hundreds of faces are hundreds of voices.
Hundreds of stories answering the same simple question: “What have they never told you?”
The faces seek the words, and the words seek the faces. It’s a silent dialogue, a cemetery of glances and suspended phrases.
Everything is held up by light, thin, fragile pins. The images sway, in a precarious balance. Silences that weigh heavily. Breaths long denied.
Hundreds of stories. Hundreds of confessions. An unyielding and necessary order.
I am building the cemetery of doubt: a space where unspoken words, unresolved secrets, and incomplete emotions finally find peace.

Published: January 2025

Afghanistan faces significant challenges in meeting its growing energy demands, with the building sector consuming a substantial portion of its energy supply. The country increasingly turns to solar energy as a clean and sustainable alternative to address these challenges. While previous studies have explored solar energy potential in Afghanistan, there is a lack of comprehensive research focusing on building sector applications and the interplay of climatic and geometrical factors. This study aims to assess the potential of solar energy for the building sector in Afghanistan by examining the influence of climatic and geometrical factors. A systematic literature review was conducted to identify existing research and data on solar energy resources, building characteristics, and energy consumption patterns. The findings reveal that Afghanistan possesses substantial solar energy potential, particularly in the southwest and west regions. Building orientation, insulation, and shading are identified as crucial factors influencing solar energy performance. By exploring the suitability of various solar technologies, including solar photovoltaic, solar thermal, and solar lighting systems, this research contributes to the knowledge base on solar energy in Afghanistan. It provides insights for policymakers and practitioners seeking to promote sustainable building practices.
Магнитная левитация, основанная на ослаблении воздействия одного из магнитных полей на источник другого магнитного поля при взаимодействии двух магнитных полей.( версия 2)
Authors: Дударев Валерий
Published: January 2025

В статье рассматриваются устройство и способ создания электромагнитной силы, имеющей строго определенный вектор действия. Для силы Лоренца при взаимодействии точечных заряженных частиц нарушается третий закон Ньютона. Восстановить справедливость этого закона Ньютона в случае силы Лоренца можно переформулировав его как закон сохранения импульса (ЗСИ) в замкнутой системе из частиц и электромагнитного поля. При этом рассматривается взаимодействие в однородной и изотропной среде. В случае магнитного поля распространяющегося в однородной и изотропной среде, создаваемого электрическими зарядами одного проводника, оно воздействует на электрические заряды другого проводника, при этом возникает сила Ампера. Второй проводник создает собственное магнитное поле, которое воздействует на заряды первого проводника и создает противодействующую силу Ампера. В этом случае две действующие противоположно силы уравновешивают друг друга в рассматриваемой системе. Предлагаемая конструкция является неоднородной и неизотропной средой, которая разделяет пути распространения магнитных полей таким образом, что противодействующая сила значительно ослабляется или не возникает совсем в рассматриваемом устройстве. Принцип равенства действующей и противодействующей сил не выполняется.
Planning the Coordinate Measurements of a Freeform Surface after Milling based on a CAD Model Simulating the Surface after Machining
Authors: Werner Andrzej , Poniatowska Małgorzata
Published: January 2025

This paper proposes the planning of coordinate measurements of freeform surfaces based on a model simulating the surface after machining. This model is created by the determination of a theoretical tool deflection during machining. The determined components of the simulated machining deviations are used in the reconstruction of the nominal CAD model of the surface into a model simulating the geometry of the surface after machining. This model is subdivided into areas corresponding to the assumed machining deviation intervals. This makes it possible to control the number and distribution of measuring points in separate sections of the manufactured surface. Coordinate measurements of the machined surface are made in areas where maximum deviations are expected. Here, the number and distribution of measuring points are controlled over a wide range. Coordinate measurements in other areas are carried out with significantly fewer points or may be omitted altogether. This approach makes it possible to reduce the measurement time without losing important information affecting the evaluation result. The method proposed in this paper has been tested on samples containing freeform surface. The test object was manufactured using a 3-axis milling technique with a spherical end mill.

The rapid advancement of artificial intelligence (AI) within Industry 4.0 has transformed manufacturing processes, shifting from traditional automation to more collaborative AI-human partnerships. While AI promises enhanced efficiency, precision, and productivity, the success of these systems relies heavily on the trust established between human operators and AI technologies. This paper explores the critical factors influencing trust in AI-human partnerships in the manufacturing sector, emphasizing the need for transparency, accountability, and ethical AI design. Drawing on a multi-disciplinary literature review and empirical studies, we identify key drivers of trust, including human preferences for system transparency, the explainability of AI decisions, and the reliability of AI systems in dynamic production environments. Furthermore, the paper examines the challenges associated with trust-building, such as overcoming fear of job displacement and managing perceived risks of AI errors. The findings contribute to the growing body of knowledge on human-centric AI design and offer practical recommendations for fostering trust to ensure successful AI-human collaboration in manufacturing settings. By transitioning from purely automated systems to collaborative partnerships, manufacturers can unlock the full potential of AI while maintaining a workforce that is confident in AI’s reliability and ethical alignment.

Published: January 2025

The analysis of the reparation procedure of the damaged turbine diaphragm from the ironworks plant, which was subjected to wear during the long-term exploitation process, is presented in this paper. The two-thirds of the bearing volume of the turbine diaphragm, made of grey cast iron EN-GJL-150, were damaged, and its functional properties were lost. The reparation was executed by the multi-layer hard-facing process. The procedure included verification of the material’s chemical composition, mechanical properties and metallographic structure, necessary for definition of the appropriate methodology for the part’s rehabilitation. The hard-facing was executed with preheating, as well as the post-welding heat treatment, with specifically selected filler materials and all the adequate welding process parameters. The executed hard-facing procedure turned out to be the cost efficient since, as a rule, the costs of reparation did not exceed 20 % of the price of that would be paid for acquiring the new part.

Published: January 2025

This article presents the latest statistical data on the volume of asbestos mining production and asbestos products trade in the world. The legal conditions for the management of asbestos and used asbestos-cement products are characterized. The resources of asbestos-cement products incorporated into roof coverings in 27 European Union countries are identified. An attempt is made to answer the question of whether the renovation of buildings, included in the European Union policy as a key initiative aimed at increasing energy efficiency in the construction sector, will contribute to the removal of asbestos-cement products and the purification of air from asbestos dust. In addition, an assessment was made of the impact of new legal regulations in the EU on activities related to the management of asbestos and asbestos waste materials, and thus on the occupational safety of construction workers.

Published: January 2025

In today’s competitive business environment, effectively analyzing, evaluating, and resolving product quality problems is critical to maintaining customer satisfaction, reducing financial losses, and preserving a company’s reputation. This study prioritizes internal and external quality problems in paperboard packaging using selected quality management tools. Product quality problems are categorized based on their frequency of occurrence and financial losses. Three quality management tools are used: the Pareto-Lorenz diagram, the matrix data analysis diagram, and the box plot. The Pareto-Lorenz diagram identified the key quality problems that generate the highest number of events and the greatest financial losses, consistent with the 80/20 rule. The matrix data analysis diagram divided the quality problems into four groups based on their combined impact, indicating critical problems for both categories. The box plot identified outliers and extremes, revealing quality problems with significantly higher frequency and financial impact than others. All quality tools used identified the overprint complaint with code 403 as critical. The results highlight the effectiveness of the quality management tools used in prioritizing product quality problems.
