THE EFFECT OF QUENCHING TREATMENT BY VARIATION OF COOLING MEDIA (WATER, USED OIL, COOKING OIL) ON EGREK HARDNESS
Authors: Putri Fenoria , Gunawan Indra , Rizky Dany Agung
Published: July 2024

Oil palm is harvested using the egrek agricultural implement. Using water for gilding, the blacksmith's egrek is toughened. The egrek that blacksmiths manufacture frequently is tarnished and worn out. Oil palm growers are consequently forced to swap them out for new ones.The product's economic value decreases as a result. Because of incorrect heat treatment, the cause of egrek is easily destroyed. The goal of this research was to ascertain how the heat treatment procedure affected how hard the quenched egrek was. Rockwell hardness test results. The hardness of the quenched egrek can be affected by changes in the water chilling medium, utilized oil, or cooking oil, according to statistical data processing using ANOVA and supported by the use of design expert software. Having an average carbon content of 0.379%, the raw material is made up of medium carbon steel. According to the results of the hardness test, the cooking oil cooling medium quenching process, which occurs at an average temperature of 800°C and a hardness value of 50.1 HRC, produces the average minimum hardness value, while the water cooling medium, which has an average hardness value of 60.4 HRC, produces the average maximum hardness value. The percentage contribution calculation reveals that used oil and cooking oil are the cooling media that have the greatest impact on the hardness level, with used oil contributing 96.37% and cooking oil contributing 96.61%, respectively, while water cooling media contribute 88.41%.

Published: July 2024

The purpose of this study is to analyze the effect of our gradient infill on the mechanical behavior of polylactide acid (PLA) materials resulting from 3d printing, which has an impact on the efficiency of material use while still providing good mechanical support. In this study, the specimens were designed using nTopology software and there were 4 variations of the structure, namely square, honeycomb, diamond, and gyroid, each of which was made gradient and non-gradient, then a bending test was carried out to determine its mechanical behavior thats PLA materials. The results of this study indicate that a comparison between specimens with gradient and non-gradient models with 50% porosity can increase the deflection of the specimen, namely square 15.7-19.1 mm, honeycomb 16.3-20.6 mm, Diamond 19.7-21.8 mm, and gyroid 20.3-22.1 mm, with an average deflection of 2.04 mm. In addition, there is a linear correlation of the relationship between thickness to deflection and flexural modulus whereas the thickness value increases, the deflection and flexural modulus will increase. The conclusion of this research is that giving a gradient to the structure can improve mechanical behavior, especially deflection.

Authors: Nasrah Perez , Homzah Ozkar F.
Published: July 2024

Penelitian ini menganalisis kerusakan pada line ducting scrubbing sistem unit di pabrik NPK-1 PT Pusri Palembang dan bertujuan untuk menentukan penyebab utama kegagalan dan mengidentifikasi solusi perbaikan yang tepat. Penyebab utama kegagalan ini disimpulkan sebagai penurunan kekuatan ducting line akibat korosi pada sisi dalam pipa ducting yang terbuat dari carbon steel SS400. Dalam penelitian ini, dilakukan kajian terhadap design awal material ducting, pemeriksaan ketebalan pipa ducting yang rusak, serta pemeriksaan visual. Hasilnya menunjukkan pengurangan ketebalan dinding pipa rata-rata hingga 70% akibat korosi. Kekuatan ducting dipengaruhi beban tetap yang ditumpangkan pada pipa ducting dan daya dukung oleh perpipaan, namun korosi pada permukaan sisi dalam pipa yang bersentuhan langsung dengan debu proses korosif dan higroskopis menyebabkan penurunan kekuatan dinding ducting terhadap beban aksial dan lateral. Kegagalan pada pipa ducting ini berdampak pada kerugian dan unschedule shutdown proses produksi, meningkatkan biaya perbaikan, dan meningkatkan risiko kecelakaan kerja. Tindakan perbaikan yang direkomendasikan adalah penggunaan bahan pipa ducting yang tahan terhadap korosi, seperti stainless steel grade SS304. Selain itu, disarankan juga melakukan pemantauan kondisi pipa secara berkala, pembersihan debu proses secara teratur pada sisi dalam pipa ducting, dan pengendalian laju aliran debu pada sistem scrubbing. Langkah-langkah ini diharapkan dapat mengurangi risiko korosi untuk menjaga kekuatan ducting, sehingga meminimalisir kegagalan sistem dan menjaga kehandalan operasional pabrik pupuk NPK.
Inelastic Cyclic Tests of Grade 80 (550 MPa) Bars with Mechanical Splices
Authors: Abdullah Wrya , Dolati Seyed Sasan Khedmatgozar , Basnet Arjun
Published: July 2024

This study addresses low-cycle fatigue performance of high-strength steel reinforcement bars (HSRB) when used with mechanical couplers due to the growing demand for higher-strength steel reinforcement bars in both seismic and non-seismic applications, driven by the need to reduce bar congestion, lower material quantities, and consider economic and environmental factors. Low-cycle fatigue involves material failure owing to a finite number of load or deformation cycles, generally occurring under substantial strain rates that surpasses the yielding limit. The experimental program assesses the fatigue behavior of HSRB produced using microalloying, quenching, and tempering techniques, coupled with mechanical couplers (eleven different types) from five companies in the United Stated of America. The study highlights significant differences in fatigue endurance based on the type and make of couplers and suggests potential improvements in manufacturing processes to enhance fatigue resistance. It is found that the mechanical couplers sustain a loading protocol of (-1% to 3%) when there is a clear distance of 2 times the diameter of the bar between the coupler and the gripping machine from top to bottom. The coupled bars sustained a minimum of 6 half cycles and a maximum of 38 half cycles.

Published: July 2024

Concrete-filled steel tube (CFST) is a composite member consisting of a steel tube filled with concrete, resulting in an enhanced structural element used in various types of construction. This research investigates the flexural strength of CFST members with varying steel tube thicknesses of 1.5 mm and 2.0 mm and different shapes: square, rectangular, and circular. The study aims to determine the flexural strength of each shape. Fifteen beams with different cross-sections and plate thicknesses were tested experimentally in the lab. The results indicated that 2.0 mm thick CFSTs, regardless of shape, exhibited superior strength and deformation resistance compared to thinner and hollow beams. This underscores the significance of using thicker plates and concrete to enhance structural integrity and durability. Notably, rectangular CFSTs demonstrated a 91.84% increase in strength, while circular beams showed greater deflection resistance, highlighting the importance of careful material selection and design choices in structural engineering to optimize performance and resilience under stress.
Effect of Soil Stabilization on Structural Design of Flexible Pavement
Authors: Saleh Shalaw Abdullah , Ismael Rahel Shwana , Abas Binar Salman
Published: July 2024

Inadequate subgrade conditions often diminish the lifespan of pavements built on these soils. However, this challenge can be addressed through various methods, including soil stabilization, which enhances soil strength. This research focuses on soil stabilization using two types of waste materials (rubber and plastic) as additives in concentrations of 5%, 10%, and 15%, along with a consistent cement inclusion of 3% across all samples. Different tests, such as Sieve analysis, Atterberg Limits, Specific Gravity, Standard proctor Test and California Bearing Ratio, were performed for both the soil and the additive materials. As a result, this stabilization approach improved the California Bearing Ratio (CBR), leading to thinner pavement layers, which potentially lowers construction costs. Notably, the highest CBR observed was 49.95% with 10% plastic, while the top result for rubber was a 28.01% CBR at 5% inclusion. These enhancements in CBR values contributed to reducing the total thickness of the pavement layers by (435 mm) for both materials.

Published: July 2024

This study explores the two distinct parts of engineering management: engineering product management and engineering project management. A qualitative systematic review method was employed, using purposively sampled literature and a desk-based research approach. Using thematic analysis, the researchers produced significant data findings. The findings suggest that Engineering Project Management and Engineering Product Development play a vital role in achieving success in engineering projects. While they possess distinct principles, practices, and concepts, they share important management techniques in the business realm. The findings also indicate significant disparities in methods, utility and resource allocation, and quality assurance while highlighting the absence of administrative functions in Engineering Product Development compared to Engineering Project Management. Furthermore, the study notes that greater creativity and efficiency in both management practices are enabled by current technology and methodology. The study's limitations include an extensive use of literature review data and a focus on a broad target area. Consequently, this suggests a need for empirical data to enhance experience-based research and focus on a specific industry for more precise outcomes.

Filariasis is a very important public health problem endemic in tropical and subtropical countries. It is a debilitating disease with significant socioeconomic burden. In 2016, lymphatic filariasis was successfully eliminated from the Maldives, which was certified by WHO. We report a case of filariasis detected by a rapid antigen test while undergoing a screening program conducted by Health Protection Agency, Maldives in December 2023. The patient was asymptomatic and showed no peripheral blood eosinophilia. Conventional blood smears were negative. Nevertheless, buffy coat smear served as a promising test in detection of parasite, thus confirming the re-emergence of the disease in the country. Therefore, our study highlight the significance of buffy coat smears in detection of hemoparasites. We also focus on the importance of surveillance system in order to sustain the disease elimination goal that was already achieved.

A ascensão dos cigarros eletrônicos, ou vaping, é notável, sendo vistos por muitos como uma alternativa menos prejudicial ao tabagismo convencional. No entanto, preocupações surgem sobre os efeitos adversos desses dispositivos no sistema respiratório. Esta revisão investiga o impacto dos cigarros eletrônicos na função pulmonar e na saúde respiratória. Com base em evidências científicas, este artigo avaliar os efeitos do vaping no sistema respiratório, focando em patologias pulmonares e alterações funcionais resultantes desse hábito. Foi realizada uma revisão narrativa da literatura em bases de dados como PubMed, Scopus e Web of Science, incluindo pesquisas sobre os impactos respiratórios do vaping. A busca abrangeu artigos em inglês, espanhol e português. Os resultados indicam uma correlação significativa entre o uso de cigarros eletrônicos e sintomas respiratórios adversos, como tosse, sibilância e dificuldade respiratória. Estudos longitudinais sugerem que o vaping pode contribuir para o declínio da função pulmonar e para o desenvolvimento de doenças respiratórias crônicas, como bronquite e pneumonite. Substâncias tóxicas presentes nos aerossóis desses dispositivos podem induzir inflamação pulmonar e dano alveolar. Apesar dessas constatações, há necessidade urgente de mais estudos que explorem os mecanismos subjacentes e avaliem o impacto a longo prazo do uso contínuo de cigarros eletrônicos. A revisão destaca a importância de regulamentações rigorosas e campanhas educativas para conscientizar sobre os riscos do vaping, especialmente na proteção de jovens e populações vulneráveis. Somente com uma compreensão mais profunda dos efeitos dos cigarros eletrônicos será possível desenvolver políticas de saúde pública eficazes e garantir a proteção respiratória da população.

A partir de 20 de abril de 2021, foi lançada no Brasil a “Década da Ciência Oceânica para o Desenvolvimento Sustentável” (2021-2030), alinhada com a proposta da ONU da “Década dos Oceanos” para conscientizar a população em todo o mundo sobre sua importância e mobilizar atores públicos, privados e da sociedade civil em ações que favoreçam a saúde e a sustentabilidade dos mares. Os pescadores artesanais dependem diretamente dos oceanos para sua sobrevivência.  Muitos desses pescadores vem enfrentando desafios, como a pesca excessiva, a poluição dos oceanos, a degradação dos habitats marinhos e as mudanças climáticas, que ameaçam a sustentabilidade de suas atividades. Nesse sentido o conhecimento da realidade de vida dos pescadores se mostra uma importante ferramenta para desenvolvimento de projetos que auxiliem, capacitem e promovam a manutenção das tradições da pesca artesanal. O presente trabalho aborda um projeto de caracterização e ações junto à Comunidade de Pescadores Artesanais em Paquetá. O objetivo principal foi compreender a atividade pesqueira da pesca artesanal, seus desafios socioambientais e fornecer insights valiosos com o potencial de orientar ações que promovam a sustentabilidade da pesca e melhorem as condições de vida das comunidades pesqueiras. Este estudo foi subdividido em seções, na primeira uma caracterização pessoal dos pescadores e da atividade pesqueira foi realizada. Dados referentes as artes de pesca utilizadas, meio flutuante, esforço de pesca, espécies capturadas e entraves a atividade foram registrados. Em seguida, as relações socioambientais foram analisadas, incluindo a complexa ligação com os ecossistemas marinhos e percepções em relação aos efeitos prejudiciais da poluição sobre a pesca. Nos entraves da atividade, a poluição ocupou um papel de destaque, seguida da falta de organização adequada no setor. Uma grande parcela de pescadores declarou não possuir registro geral da pesca (RGP) e desconhecer seus direitos. A arte de pesca mais utilizada foi a rede de emalhe e espera. Foram identificadas 19 espécies de pescado mais capturados. Como desdobramento da caracterização oficinas de capacitação foram implementadas e também realizadas rodadas de auxílio ao Registro Geral da Pesca (RGP)

A digitális munkahely jogi és nem jogi kihívásai
Authors: Mélypataki Gábor , Solymosi-Szekeres Bernadett
Published: July 2024

A digitális munkahely egy fogalmi evolúció eredménye, és számos kihívást rejteget magában, amelyek több szempontból érintik a munkajogot. Ilyen kihívás a távmunka és a home office kérdése, ám a kihívások közül több is elsőre nem feltétlenül tűnik (munka)jogi természetűnek, mint a quiet quitting. A tanulmányunkban olyan forrásokat is feldolgozunk, mely a digitális munkahely egyes korszakait értelmezik. Ezekből rajzolódik ki a fogalmi evolúció. Az említett fogalmakat szükséges a munkajog szemüvegén keresztül is vizsgálni, mivel azokhoz számos munkajogi jellegű szankció kapcsolható. A tanulmány ennek megfelelően a munkahelyek dematerializálódására épít, amely különösen problémás lehet egy bizalmi jogviszonyban, illetve több szinten összefügg a generációk közötti különbségekkel. Bemutatásra kerül több különböző fogalmi megközelítés, dogmatikai kérdések vizsgálata, illetve a hajsza-kultúra és az arra reagáló munkavállalók változó attitűdje, analizálva a problémák jogi és nem jogi keresztmetszeteit, mindezt a munkajog szemszögéből. A jogi kérdések vizsgálata azonban igényli több olyan előkérdés megválaszolását, melyek nélkül a jogi összefüggések is sokkal nehezebben lehetnének értelmezhetők. A kutatásunk során végig holisztikus keretrendszerben vizsgáltuk az összefüggéseket. Ennek oka a téma komplexitása és az, hogy talán így láttatható a legjobban, hogyan kerül ki a digitális munkahely szabályozási igénye a nemzeti jogalkotás terepéről minimum uniós szintre, de akár nemzetközi szintekre is.

Из обсуждения проблем культурной принадлежности и датировки ряда
погребений, прежде отнесенных к раннему железному веку Армении,
можно сделать вывод, что они требуют актуального решения. При датировке археологического комплекса распространенная практика отыскивания параллелей отдельных предметов не имеет перспективы. Следуя
этому принципу, в лучшем случае можно выяснить временной интервал
образования данного археологического комплекса, а не его культурную
принадлежность. Приведенные примеры показывают, что основанная на
типологии любая относительная хронология будет нуждаться в уточнении, пока в обсуждаемом регионе не разделены археологические культуры
данной эпохи. Кроме того, нужно иметь в виду, что для неповрежденных
закрытых комплексов датирующими должны быть факты или предметы,
имеющие позднюю хронологию.
При выделении некоторых закрытых комплексов: с киммерийскими
признаками принят за основу тезис, который гласит: чтобы опознать культурные типы, нужно исходить из конкретной археологической культуры.
Культурная принадлежность включенных в выборку групп погребений из
Ширакавана, Вардакара, Спандаряна, Манташа, Гюмри, Воскеаска и
других могильников наводит на мысль о необходимости датировать их
немного более поздним периодом. Таким образом, рассматриваемые
погребения Ширака, в совокупности, могут быть датированы концом VIII
– VII в. до н. э.

Согласно шведскому мифологу Стигу Викандеру армянская легенда о рождении виноградной лозы из телячьей кости имеет параллель в скандинавском фольклоре. Легенда связана с патриархом Ноем (Абраамом). И поскольку армянское слово ort‘ (лоза) считается происходящим от слова hort‘ (теленок), и они являются синонимами, впервые предпринята попытка связать это сходство с данной легендой. Дополнительным доказательством является тот факт, что не случайно такое же сходство в звучании и значении обнаруживается и в некоторых романских языках. Викандер не упоминает, какая из скандинавских легенд имеет сходство с армянской. Он имел в виду легенду о возрождении коз из костей. Источник этой легенды – «Младшая Эдда» исландского скальда Снорри Стурлусона, написанная в XIII веке, частично – «Большая Эдда». Принимая во внимание древние отношения между армянами и скандинавами, не исключено, что скандинавы заимствовали у армян эпизод рождения новой жизни из костей животного.

Published: July 2024

The proliferation of Internet of Things (IoT) devices has transformed various industries by providing smart and automated solutions. However, the extensive connectivity and diverse nature of IoT devices have also introduced significant security challenges, particularly in terms of network intrusion. This paper explores the development and implementation of an Intrusion Detection System (IDS) for IoT networks using Machine learning techniques. The proposed IDS aims to detect and mitigate various cyber threats by analyzing network traffic and identifying anomalous patterns indicative of intrusions. This research contributes to the field of IoT security by providing a robust and scalable intrusion detection solution that leverages the power of machine learning.
Securing Modern Storage Stacks
Authors:   , Bacs Andrei
Published: July 2024

Modern storage stacks implement persistent memory which is a core component of
computing systems. This dissertation considers threats that affect the storage stack,
discussing solutions to analyze and reduce the resulting attack surface in pre- and
post-compromise scenarios.
On the attack surface analysis front, we first identified and studied a new class
of advanced attacks based on a timing side channel (pre-compromise scenario). The
latter originates from the filesystem deduplication feature of modern filesystems like
ZFS and Btrfs. We showed how an attacker can abuse the side channel to leak
sensitive data at the byte or block granularity, bypassing traditional filesystem access
controls. We proposed a mitigation where the read and write operations exhibit the
same behavior in the time domain, regardless of the presence of the data on storage.
To explore the post-compromise attack surface, we introduced lightweight instrumentation to track low-level storage operations, observing any malicious interactions with the storage stack. This was helpful to study an important class of persistent malware (bootkits) for a large period of time. As a result, we derived its storage-related characteristics and proposed mitigations for it.
On the attack surface reduction front, we first studied and proposed a generic
intrusion detection system for the virtualized storage stack with low overhead (pre-
compromise scenario). Next, we proposed a post-compromise solution for intrusion
recovery, which is operating system agnostic and uses heavyweight instrumentation
to precisely track malicious data through the system at the byte granularity. In the
process, we addressed important challenges such as reducing the semantic gap to
have a more precise recovery granularity and hiding the instrumentation overhead
by means of a decoupled security model.

One of Papua's special autonomy rights is the existence of the Papuan People's Council (MRP) as the cultural representation of the indigenous Papuan population who are given certain powers. Article 1 point 6 of Government Regulation Number 54 of 2004 concerning the Papuan People's Assembly defines: "The Papuan People's Assembly, hereinafter abbreviated as MRP, is the cultural representation of indigenous Papuans, which has certain authority in the context of protecting the rights of indigenous Papuans based on respect for customs and culture, empowering women, and strengthening religious harmony." The problem is how to regulate the functions and rights of MRP legislation in the formation of Special Regional Regulations. How is the implementation of the rights and tasks of the MRP in the context of protecting the traditional rights of Indigenous Papuans regarding the exploitation of natural resources? What will be the legal protection for Indigenous Papuans through the Papuan People's Assembly (MRP) in the future (ius constituendum)? The research method is a normative legal or juridical research method supported by empirical data. The results of the research are that the protection of the basic rights of indigenous Papuans by the Papuan People's Assembly (MRP) in carrying out its authority to provide consideration and approval of draft regional regulations has not had a significant impact on achievement. The welfare of indigenous Papuans is the target/objective of affirmative action and is the aim of Law Number 21 of 2001.

Authors: Alves Jonas Zumerli , Borba Érika Loureiro
Published: July 2024

A obesidade é um problema de saúde pública significativo que afeta muitas pessoas em todo o mundo. A Organização Mundial da Saúde (OMS) a considera uma doença crônica não transmissível, caracterizada pelo acúmulo excessivo de tecido adiposo, o que aumenta o risco de desenvolver outras condições médicas. Sendo assim, o objetivo da pesquisa foi revisar os diversos aspectos que norteiam essa patologia para melhor compreensão dos fatores que dificultam o seu combate. Tratar a obesidade é crucial para entender melhor as necessidades de saúde da população. O diagnóstico da obesidade pode ser realizado por diversos métodos. Embora os exames de imagem sejam mais sensíveis para medir os depósitos de gordura subcutânea, os índices antropométricos são mais comumente utilizados devido à sua facilidade de implementação. Um desses índices é o Índice de Massa Corporal (IMC), que calcula a relação entre peso e altura e é capaz de classificar o estado nutricional. Além do IMC, a circunferência da cintura também é amplamente usada para avaliar a composição do tecido adiposo. É crucial investir em estratégias de prevenção e intervenção nutricional para reduzir o desenvolvimento da obesidade, especialmente entre os grupos mais suscetíveis. Essas estratégias podem ajudar a diminuir as internações causadas pela obesidade e promover uma melhor qualidade de vida para a população brasileira. Utilizou-se da metodologia de revisão de literatura. E a principal conclusão foi que a obesidade transcende apenas os fatores biológicos e a sua fisiopatologia multifatorial está relacionada às dificuldades no manejo dessa patologia

The object of research is a place of business that produces household needs and wood-based industries. One of the products it produces is a minimalist wall shelf. In the period January –December 2021 minimalist wall shelf products are the products with the most defects. Manufacturing companies in this study have a product defect tolerance limit of 5% of the total production, but minimalist wall shelf products have a defect of 5.64%. This study aims to determine the types of defects that occur in wall shelf products, identify the causes of defects minimalist wall shelves and provide suggestions for improvements to reduce the number of future defects. In this research the method used is DMAIC. In the minimalist wall shelf production process, 4 types of defects were found. Based on the Pareto diagram, it was determined that the type of lacquer defect was not suitable to be the most dominant type of defect, namely 80.1%, it was also found that the DPMO value and sigma value on minimalist wall shelves were 14,100 and 3.69. Based on the analysis of the fishbone diagram method and Failure Mode and Effect Analysis (FMEA), it is known that the main root cause of product defects is a dirty, dusty and windy environment with an RPN (Risk Priority Number) value of 448.

The World Health Organization (WHO) estimates that Mycobacterium tuberculosis, the single agent causing pulmonary tuberculosis (TB), infects 1.8 billion people, or around one-quarter of the world's total population. In Indonesia, there are an estimated 969,000 cases of pulmonary TB, including 443,235 reported cases. Prison is a high transmission site for pulmonary TB. Prison circumstances, such as high occupancy capacity, inadequate ventilation and nutrition, difficulties accessing health care, inadequate treatment, and weak patient immunity, are some of the variables influencing this. Knowledge on the origins, transmission, preventative strategies, and early diagnosis of pulmonary TB infection is essential for the prisoner in order to change attitudes toward pulmonary TB infection. This study used a descriptive approach to generate a description of the prevalence and risk factors for the spread of pulmonary tuberculosis in the Prison of Jember Class IIA. Based on the WHO-recommended screening technique, 4 male prisoners in the Prison of Jember Class IIA (8.5%) tested positive for pulmonary tuberculosis. There are various aspects that are difficult to include into environmental health standards, particularly infectious diseases like pulmonary tuberculosis, such as the density of people in a single cell room and the construction of the building and the services housed inside it. Policymakers must pay attention to the requirement to create appropriate isolation rooms and, at the very least, satisfy room standards for patients suffering from pulmonary tuberculosis.
