Authors: Yunialdi Andre
Published: March 2024

Tesis ini berjudul tentang Pertimbangan Hukum Hakim Yang Mengabulkan Gugatan Penggugat: Studi Eksekusi Hak Atas Tanah. Yang menarik dalam pembahasan ini adalah mengenai Putusan Pengadilan Negeri Palembang yang sudah dieksekusi, digugat oleh dr Meliza Zubir karena yang dieksekusi adalah salah satu nya tanah miliknya yang sudah bersertifikat, yang diperoleh dari jual beli pemilik surat atas nama PT. Amen Mulia sebelum perkara berlangsung dengan dasar Meliza Zubir bukanlah pihak dan serta sertifikat tanahnya tidak tercantum dalam amar putusan No. 172/Pdt.G/2015/PN.PLg Jo Putusan Nomor 64/PDT/2016/PT PLG Jis Putusan Nomor 87K/PDT/2017 yang berarti tidak mempunyai kekuatan hukum mengikat dan tidak memiliki nilai eksekutorial putusan tersebut terhadap Meliza zubir karena tidak termasuk sebagai pihak dalam perkara sebagai dasar eksekusi. Metode penelitian yang digunakan adalah jenis penelitian normatif dengan pendekatan perundangan-undangan, kasus, konseptual, dan analisis. Teknik penarikan kesimpulan menggunakan logika berfikir deduktif. Adapun hasil penelitian ini menunjukkan bahwa 1) adapun faktor yang menyebabkan suatu putusan ini tidak dapat dieksekusi dikarenakan gugatan penggugat kabur atau tidak jelas dan dinyatakan Non Eksecutable, 2) mengenai hambatan hukum yang di temukan dalam pelaksanaan eksekusi hak atas tanah dalam perkara tersebut adalah adanya eror in persona atau kekeliruan antara PT Amen Mulia dengan Meliza Zubir yang mana terdapat kaburnya dasar gugatan serta alasan tuntutan yang diajukan penggugat misalnya mengenai batas-batas obyek yang tidak jelas.

Published: March 2024

Dalam penegakan hukum penyalahgunaan dana margin nasabah yang diterima secara elektronik di bidang perdagangan berjangka komiditi (PBK) mengalami kendala dari faktor budaya dan masyarakat. Dari faktor budaya, terdapat kelemahan budaya hukum Pialang Berjangka dan Wakil Pialang karena tidak mendampingi dan memberi edukasi kepada nasabah dalam melaksanakan pengisian formulir-formulir elektronik penerimaan nasabah khususnya formulir mengenai adanya risiko dan pernyataan nasabah untuk tidak memberitahukan password akun transaksi kepada pihak manapun termasuk ke Wakil Pialang kecuali telah diberi perintah secara tertulis. Dari faktor masyarakat, khususnya selaku nasabah, yang tidak bersikap waspada terhadap risiko, mempercayai janji-janji keuntungan maksimal, dan memberikan password akun dan mempercayakan transaksi PBK kepada Wakil Pialang, tanpa perintah tertulis, serta nasabah yang tidak melaporkan dugaan tindak pidana PBK ke pihak yang berwajib. Di masa mendatang, secara penal diperlukan kebijakan hukum pidana dengan pelaksanaan pemidanaan yang ditujukan kepada Wakil Pialang dan Pialang Berjangka sebagai korporasi. Secara non penal, Bappebti melaksanakan sosialisasi prosedur penerimaan nasabah secara elektronik, serta melaksanakan pembinaan dan pengawasan bagi Wakil Pialang dan Pialang Berjangka yang menerima nasabah secara elektronik.

Countries that are still developing experience significant disparities in access to railway services, as these nations also grapple with societal inequality issues that remain unaddressed. In developed countries, railway transportation systems serve as the primary mode of transportation for both passengers and goods. However, in recent years, studies on disparities in developed countries have increased, while literature concerning developing countries remains scarce. Therefore, this study takes place in Thailand, a developing country facing significant population disparities. The objective is to examine factors contributing to these disparities in access to railway transportation systems across cities, using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to identify user disparities. The sample group comprises 1,252 randomly selected railway users from various regions in Thailand, obtained through Stratified Random Sampling. The results reveal seven dimensions of disparities: cultural, spatial, societal, political, knowledge-based, economic, and environmental. The CFA results also highlight cultural disparities as a significant factor in explaining access disparities among railway users. These findings can inform relevant organizations, aiding them in better understanding the actual needs of railway users and aligning railway development plans accordingly. Ultimately, this contributes to policy development aimed at reducing access disparities and fostering a more equitable society. Doi: 10.28991/CEJ-2024-010-03-01 Full Text: PDF

Published: March 2024

The conventional approach to achieving optimal printability and buildability in 3D printing mortar relies heavily on cement, which is both costly and environmentally detrimental due to substantial carbon emissions from its production. This study aims to mitigate these issues by investigating the viability of slag as a partial substitute for cement, with the goal of developing an eco-friendly alternative. The newly formulated mortar, featuring a 30% reduction in cement content (from 830 to 581 kg/m3) and the inclusion of 0.10% micro-fibers, exhibits properties comparable to conventional 3D printing mortar. The research is structured into two parts: Part 1 focuses on determining the optimal fiber content, while Part 2 delves into the investigation of fiber-reinforced mortar with reduced cement content for 3D printing. Criteria were established to ensure mortar flow at 115%, initial printable time below 60 minutes, and 7-day compressive strength exceeding 28 MPa. Part 1 results indicate that a fiber content of 0.1% by volume meets the specified requirements. In Part 2, it was observed that increasing the slag replacement percentage extended the initial printable time and time gap. However, even at a 30% replacement rate, the initial printable time remained within the acceptable range, partially attributed to the presence of fibers in the mix. Additionally, higher slag content led to increased flow and reduced filament height in the mixes. Notably, all formulations surpassed the 7-day compressive strength threshold. These findings underscore the potential of slag as a sustainable alternative to cement in 3D printing fiber-reinforced mortar, offering promising prospects for environmentally friendly construction practices. Doi: 10.28991/CEJ-2024-010-03-010 Full Text: PDF
Dynamic Buckling Analysis of Ductile Damage Evolution for Thin Shell With Lemaitre’s Model
Authors: Hammar Iheb , Djermane Mohamed , Amieur Belkacem
Published: March 2024

Thin-shell structures are used in several fields of construction and are often exposed to severe dynamic environments, making them susceptible to dynamic instabilities. These instabilities are typically preceded by varying degrees of damage to the shell, justifying the need to incorporate this behavior in the formulation of the finite elements used. The objective of this work is to evaluate the different dynamic instability criterion in the presence of damage, afterward, evaluate the influence of this behavior on the stability of shells subjected to the dynamic excitations. The methodology of this project is essentially numerical, based on the finite element method. We are asked to program the introduction of damaging behavior and Lemaitre’s model criteria in the DYNCOQ program developed locally. To examine the results, two examples extracted from the literature were presented. The first model aimed to confirm the proper functioning of the program and the convergence of the plasticity criterion (Lemaitre's model). As for the second model, it allows us to test the dynamic instability. A comparison was made with experimental data from previously published literature, revealing a strong agreement between the calculated and experimental results. The obtained results prove the utility of considering this behavior in the shell analysis. Doi: 10.28991/CEJ-2024-010-03-012 Full Text: PDF

Published: March 2024

The purpose of the study is an experimental determination of the stress-related characteristics of the structural steel produced in the Republic of Kazakhstan for use in conventional and earthquake-resistive construction. Since 2015, the construction industry has been using European regulatory documents—Eurocodes—as a statutory framework. In particular, the Eurocode 1993 for steel structures and the Eurocode 1998 for the design of earthquake-resistant structures However, the study of stress-related properties of structural steel using experimental methods of ISO standards has not been performed. Therefore, in the construction industry of the Republic of Kazakhstan, steel-work structures have been used in fairly limited volume since 2015. The experimental studies were conducted on 7 types of structural steel with thicknesses of 8, 10, and 20 mm manufactured by Arcelor Mittal. The yield strength, ultimate tensile strength (breaking stress), and tensile strength at break were studied. The experimental studies were carried out on the basis of ISO standards. In each test run, 5 samples were used. In two series, 20 samples each were tested, which made it possible to estimate the yield strength and strength distribution functions. The correlation relationships between Brinell hardness and yield and strength limits have been studied. As a result of experimental studies, it was found that the strength and deformability parameters fully comply with the requirements of Eurocode 1993. Based on the application of the Student's test, it is revealed that the distribution functions of yield strength and resistance correspond to the normal law (Gaussian function). The calculation of a three-story, two-span residential building with box section columns for construction in an area with a seismicity of 8 points is performed by the finite element method. The work results will significantly increase the scope of Kazakhstani structural steel use in seismic and conventional areas of the Republic of Kazakhstan. Doi: 10.28991/CEJ-2024-010-03-09 Full Text: PDF

Authors: Oparina Lyudmila , Gridneva Yaroslava , Barzygin Evgeniy
Published: March 2024

The relevance of the study is due to the increasing importance of large-scale construction management processes throughout the full life cycle, as well as the system-technical nature of the problems that arise in this case. To determine the effectiveness of the management system, the principles of a systematic approach can be applied, in which the subject of economic activity is considered as a single whole with an ordered structure and relationships. It has been established that currently there are many problem-oriented models (simulation, optimization, expert) containing various quantitative indicators and methods for determining effectiveness aimed at finding economically feasible management solutions and providing for their subsequent practical implementation. However, a unified methodological understanding on the issues of evaluating the effectiveness of large-scale construction management has not yet been achieved. The purpose of the study is a methodological justification of a holistic approach to evaluating the effectiveness of a large-scale construction management system. As a working hypothesis, the assumption of a direct inextricable link between the integrity of the management system and the effectiveness of its functioning is accepted. The conceptual framework of the theory of integrity, mathematical statistics, and set theory is used within the framework of a systematic approach. As a result of the conducted research, an understanding of the effectiveness of large-scale construction management has been developed as the integrity of the solutions embedded in it, expressed by a set of any assessments that adequately express the need and possibility of implementing these solutions. The economic aspect of the systemic efficiency of capital management of a construction enterprise is investigated and a variant of its cost (monetary) assessment is proposed. The result obtained in the course of the study can be used as the basis for the development of a wide class of tasks for multi-criteria optimization of the operation of any large-scale construction management system throughout the full life cycle.

Published: March 2024

Bolted joints, which are one of the detachable joining methods, are used extensively. The reliability of bolted joints is extremely important for the strength and life of the system. The determination of the number of bolts to be used in a system, the position and other data of the bolt requires very serious design and engineering studies. In this study, the design and optimization of bolted joints subjected to lateral forces are performed. For this purpose, a software has been developed in C# programming language. The software visually guides the user and asks a minimum number of questions to the designer and all other parameters are calculated by the program. The visual design of the program was done in Visual Studio environment. The graphic designs used in the software help the user to enter correct data. When the program is run for bolted joint under lateral loading, the user only enters the number of plates and force as input. Although the program performs its calculations between 1.5-2 factor of safety, it is possible to change it according to the characteristics of the design. The program developed in the light of these inputs calculates the appropriate bolt diameter, number, material and dimensions of the plates for the designed joint according to the optimum design options. The design options determined by the program are also presented to the designer visually. With the developed software, the user workload is minimized by determining the optimum options of bolted joints according to the minimum amount of user input. This resulted in significant savings in the time spent in design and engineering calculations. The user-friendly interface provides an easy and visual use. The results obtained by the program were also solved manually to check the reliability of the program.

Kegiatan budidaya ikan lele tidak terlepas dari berbagai permasalahan salah satunya penyakit. Keberhasilan budidaya ikan lele dipengaruhi oleh beberapa faktor, salah satunya adalah pengendalian serangan penyakit bakteri. Ikan lele rentan terhadap penyakit yang disebabkan oleh infeksi bakteri Aeromonas hydrophila. Bakteri A. hydrophila dapat menyebabkan Motile Aeromonas Septicemia (MAS). Pengendalian penyakit pada ikan lele (Clarias Gariepinus) sering menggunakan antibiotik jenis enrofloxacin. Penggunaan antibiotik dapat menimbulkan dampak negatif salah satunya dapat menimbulkan resistensi.Penelitian ini bertujuan untuk menganalisis jenis bakteri pada ikan lele di Kabupaten Pasuruan dan respon bakteri tersebut terhadap antibiotik enrofloxacin serta memperoleh gambaran histopatologi hati, ginjal dan limpa. Penelitian ini merupakan penelitian deskriptif dan eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL). Sampel terdiri dari 25 sampel ikan lele yang diambil dari 5 kecamatan di Kabupaten Pasuruan. Kecamatan Beji 10 sampel, Kecamatan Rembang 6 sampel, Kecamatan Purwosari 3 sampel, Kecamatan Gempol 3 sampel dan Kabupaten Bangil 3 sampel.

Для оцінювання зміни властивостей використано кут змочування водою (метод сидячої краплі), скануюча електронна мікроскопія для спостереження за структурними змінами на поверхні. Електрохімічна імпедансна спектроскопія та потенціодинамічні поляризаційні криві були використані для оцінки корозійного потенціалу.

Результати. В результаті показано, що отримані покриття не є повністю стійкими до тривалого перебування у воді. Основними дефектами є розтріскування і збільшення полярності поверхні. Це призводить до падіння кута змочування водою. Додаткове погіршення водовідштовхувальних властивостей пояснюється зменшенням адгезії полімеру до наповнювача. Згідно досліджень потенціалу самокорозії найбільш стійким виявився зразок з найбільшою кількістю мікророзмірного наповнювача і мінімальним вмістом полімеру. Для цього зразка також не спостерігалося втрати гідрофобних властивостей після тривалого занурення в корозійне середовище, хоча на поверхні утворилися тріщини.

Наукова новизна. Вперше показано, що для адитивних покриттів, одержаних пневматичним розпиленням, з ієрархічною структурою поверхні можливі суттєві зміни корозійної стійкості в залежності від фракційного співвідношення мікро- та нанорозмірних формуючих текстуру частинок.

Практична значимість. Розроблено склад адитивного покриття на основі стирол-акрилового полімеру та структуроутворюючих частинок, яке характеризується підвищеною протикорозійною здатністю за рахунок співвідношення фракцій, що дозволяє сформувати структуру з високою стабільністю водовідштовхування.

Мета. Метою цих досліджень є проаналізувати параметри зони обслуговування точки доступу мережі стандарту IEEE 802.11ac, залежно від параметрів модуляції й кодування, а також взаємний вплив суміжних мереж цієї специфікації на стабільність їх функціонування.

Методика. На підґрунті нормованих параметрів потужності випромінювання точки доступу і мінімально необхідного рівня прийнятого сигналу зроблено розрахунок максимальної відстані від точки доступу до абонентської станції, на якій можна забезпечити приймання кадрів даних у локальній мережі IEEE 802.11ac, за певного режиму модуляції й кодування (MCS). Отримані результати застосовано для оцінювання рівня електромагнітної сумісності суміжних безпроводових мереж специфікації IEEE 802.11ac.

Результати. Встановлено, що за умови обмеження випромінюваної потужності точки доступу на рівні 100 мВт високошвидкісні режими передавання даних у безпроводовій мережі IEEE 802.11ac, можна реалізувати за відсутності перешкод на шляху розповсюдження радіохвиль в радіусі 10÷15 м від точки доступу. Розмір зони обслуговування залежить від застосованого в мережі режиму модуляції й кодування, і радіус зони може змінюватись до десяти разів. Цей розмір залежить також від ширини частотної смуги радіоканалу і зменшується вдвічі, у разі збільшення частотної смуги в чотири рази. У разі зменшення випромінюваної потужності точки доступу до 60 мВт, радіус зони обслуговування зменшується на 25%. За результатами аналізу застосованих в мережах IEEE 802.11 механізмів оцінювання зайнятості частотного каналу, зроблено висновок про те, що в локаціях зі щільним розташуванням локальних мереж значний взаємний вплив може бути, як внаслідок виникнення співканальних завад, так і внаслідок міжмережевих завад суміжних частотних каналів.

Наукова новизна. Узагальнено чинники, що впливають на функціонування суміжних безпроводових мереж стандарту IEEE 802.11 на фізичному рівні та визначено числові дані, що характеризують залежність зони обслуговування мережевої точки доступу специфікації IEEE 802.11ac від режиму передавання користувацьких даних.

Практична значимість. Результати можуть бути використані під час проектування, планування та обслуговування безпроводових мереж стандарту IEEE 802.11, зі змогою сформувати прогнозну оцінку швидкості передавання даних, залежно від місця розташування користувацької станції в зоні обслуговування точки доступу та наявних перешкод на шляху розповсюдження OFDM сигналу і від наявності інших, близько розташованих мереж IEEE 802.11.

The aim of the work is to examine the possibilities of developing geotourism in the context of existing, but not yet recognised, geoheritage in the north-eastern Wielkopolska, western Poland. Pałuki is characterised by exceptional geodiversity, which has enormous potential for diversifying the present tourist offer. The valorisation method of selected 12 geosites was used, taking into account geomorphological, additional and utility categories. The results of the analytical part made it possible to identify the most valuable and geotouristically attractive geosites. They form two original geotourism trails under the common name of "Geodiversified Pałuki". In order to increase the possibilities of developing local geotourism, two proposals for thematic geotourism trail focusing on the most interesting, and highly rated, geosites in the research area are presented.
The “Charter for Jerusalem” and the Seleucid Conquest of the Southern Levant
Authors: Eckhardt Benedikt
Published: March 2024

Written soon after the battle of Panium, the letter of Antiochus III to Ptolemy son of Thraseas is a central piece of evidence in any reconstruction of the Ptolemaic-Seleucid transition in the Southern Levant. Its preservation in Josephus’ Antiquities raises questions of transmission and authenticity that are here discussed in some detail. The article also considers wider questions pertaining to the use of this document as an exemplary source illustrating Seleucid rule in this region and beyond: is what we have here unusual or standard practice? What can we learn about the image of the king, his enemies and his administrative apparatus that was projected to subjects? And can the document shed important light on royal interaction with non-polis communities, as has often been argued?

Background: This study aims to identify biomarkers through the analysis of genomic data, with the goal of understanding the potential immune mechanisms underpinning the association between sleep deprivation (SD) and the progression of COVID-19. Methods: Datasets derived from the Gene Expression Omnibus (GEO) were employed, in conjunction with a differential gene expression analysis, and several machine learning methodologies, including models of Random Forest, Support Vector Machine, and Least Absolute Shrinkage and Selection Operator (LASSO) regression. The molecular underpinnings of the identified biomarkers were further elucidated through Gene Set Enrichment Analysis (GSEA) and AUCell scoring. Results: In the research, 41 shared differentially expressed genes (DEGs) were identified, these were associated with the severity of COVID-19 and SD. Utilizing LASSO and SVM-RFE, nine optimal feature genes were selected, four of which demonstrated high diagnostic potential for severe COVID-19. The gene CD160, exhibiting the highest diagnostic value, was linked to CD8+ T cell exhaustion and the biological pathway of ribosome biosynthesis. Conclusions: This research suggests that biomarkers CD160, QPCT, SIGLEC17P, and SLC22A4 could serve as potential diagnostic tools for SD-related severe COVID-19. The substantial association of CD160 with both CD8+ T cell exhaustion and ribosomal biogenesis highlights its potential pivotal role in the pathogenesis and progression of COVID-19.
YTHDF1 Promotes Proliferation and Inhibits Apoptosis of Gastric Cancer Cells via Upregulating TCF7 mRNA Translation

Published: March 2024

Background: N6-methyladenosine (m6A) modification is one of the most common RNA modifications in mammals. m6A modification, and associated abnormal gene expression, occur during various biological processes, most notably tumorigenesis. YTH domain-containing family protein 1 (YTHDF1), a m6A reader, bind to messenger RNAs (mRNAs) containing a m6A modification and this enhances its interaction with the ribosome and promotes translation. The function of YTHDF1 in gastric cancer (GC) has been the subject of earlier studies; however, the precise mechanism underlying YTHDF1’s role in GC has not been fully elucidated. Methods: The expression of YTHDF1 was evaluated using quantitative real time polymerase chain reaction (qRT-PCR), immunohistochemistry and western blotting. CCK-8, 5-Ethynyl-2′-deoxyuridine (EdU) and flow cytometry assays were utilized to explore the effect of YTHDF1 on GC cell viability and proliferation. Transcriptome sequencing and RNA immunoprecipitation assays were utilized to explore the underlying mechanisms mediated by YTHDF1. Results: We observed that YTHDF1 is upregulated in GC cancer tissues. Knockdown of YTHDF1 in GC cells significantly inhibited proliferation and promoted apoptosis, suggesting that YTHDF1 increases proliferation and blocks apoptosis in GC cells. Mechanistically, data gathered suggest that YTHDF1 promotes the translation of the transcription factor TCF7 and this results in activation of the WNT signaling axis. Conclusions: We found that YTHDF1 was upregulated in GC and that YTHDF1 could promote GC progression through modulating the translational efficiency of TCF7. Taken together, these findings may provide a novel therapeutic target for GC.
