ABSTRACT

A level crossing is formed from a meeting between a road section and a railroad or railroad track. In this study, the crossing which is the subject or research is the level crossing on Jalan Karya Raya which is a form of meeting that can cause trffic jams. It is known that the JPL level crossing No 6a which is on Jalan Karya Raya is an  official level crossing guarded by PT.KAI. This crossing includes having a quite busy schedule of passing trains because this railway line is a route between Duri – Tanggerang and can also directly connect to Soekarno Hatta Airport so that during weekdays and traffic rush hours traffic conflicts often occur, such as congestion due ti traffic jams. The schedule of trains passing is very dense and it is common for trains to pass simultaneously at the same time so that the traffic volume increases. The JPL level crossing No 6a has quite complete sign and marking facilities such as automatic train door latch closures, sound signals, JPL officers on guard and road marking. For the condition of the facilities, sign and road marking are all clearly visible to motorists or other road users.

ABSTRAK

Perlintasan sebidang terbentuk dari perpotongan antara ruas jalan raya dengan jalur kereta api atau lintasan kereta api. Pada penelitian ini, perlintasan yang menjadi bahan penelitian yaitu perlintasan sebidang di Jalan Karya Raya yang merupakan salah satu bentuk pertemuan yang dapat menimbulkan kemacetan. Diketahui perlintasan sebidang JPL No 6a ini yang berada di Jalan Karya Raya merupakan perlintasan sebidang resmi yang dijaga oleh PT.KAI. Perlintasan ini termasuk memiliki jadwal kereta api melintas yang cukup padat karena jalur kereta api ini merupakan jalur antara Duri-Tanggerang dan bisa juga langsung menghubungkan ke Bandara Soekarno Hatta sehingga pada saat hari kerja dan jam sibuk lalu lintas sering terjadi konflik lalu lintas, seperti kemacetan karena jadwal kereta api melintas yang sangat padat dan sering terjadinya kereta api melintas secara bersamaan di waktu yang sama sehingga volume lalu lintas meningkat. Perlintasan sebidang JPL No 6a memiliki fasilitas rambu-rambu dan marka yang cukup lengkap seperti adanya penutup palang pintu kereta otomatis, adanya isyarat suara, adanya petugas JPL yang berjaga dan marka jalan. Untuk kondisi fasilitas rambu-rambu dan marka jalan semua terlihat jelas oleh pengendara atau pengguna jalan lainnya.

Authors: Alkam Rani Bastari , Bulgis Bulgis
Published: February 2024

Bahan tambah penstabil merupakan material yang dibutuhkan dalam komposisi campuran stone mastic asphalt yang berperan meningkatkan sifat kohesi antar material dalam campuran. Bahan tambah fiber mesh telah diuji pada campuran beton yang terbukti dapat meningkatkan kinerja mekanis beton namun belum dicobakan pada campuran beraspal khususnya SMA. Penelitian ini bertujuan untuk menganalisis karakteristik Marshall campuran SMA dengan fiber mesh sebagai bahan tambah. Pengujian eksperimental di laboratorium dilakukan untuk mengetahui parameter Marshall campuran yang ditambahkan fiber mesh dengan variasi kadar berat dan panjang. Hasil pengujian menunjukkan bahwa penambahan fiber mesh berpengaruh secara tidak signifikan terhadap karakteristik Marshall campuran yaitu meningkatkan density, menurunkan VIM dan VMA, dan meningkatkan nilai VFA. Dengan penambahan fiber mesh, nilai stabilitas dan MQ meningkat sampai pada batas optimum lalu kembali menurun hingga nilai yang lebih kecil dari nilai stabilitas dan MQ sampel tanpa fiber mesh. Kadar fiber mesh terbaik yaitu variasi panjang 0,36 cm sebanyak 0,3% dari total berat campuran yang mampu meningkatkan 6% nilai stabilitas dan koefisien Marshall sampel tanpa fiber mesh. Namun, tidak ada satupun variasi yang menghasilkan campuran yang memenuhi spesifikasi stabilitas SMA modifikasi yaitu minimum 750 kg. Nilai stabilitas tertinggi yang diperoleh yaitu 737,916 kg pada kadar fiber mesh optimum.

The construction project sometimes requires construction of a man-made slope. In designing of a slope, safety factor is important thing to analyze, as to prevent failure. A project in Ciawi, Bogor, it is required to build a retaining wall, with the initial step is to construct a 90° or perpendicular slope, with height of 12 m. From the analysis using Fellenius Method, for five possible conditions, it is found the value of safety factor, namely conditions without additional loading of 0,86, surcharge load of 0,84, steady state seepage of 0,60, sudden drawdown 0,61, and earthquake of 0,72, it is known that the slope does not meet the safety factor according to SNI 8460: 2017 which is 1,25, but the project has been completed and the slope has not experienced failure. This is due to the fact that in the calculation of the safety factor, the cohesion (c) and shear angle (ϕ) values are reduced, assuming that the slope will experience long-term loading and thus lose the cohesion and shear angle values, while the slope is intended for only a few months of construction and does not receive excessive loading so it does not experience cohesion and shear angle reduction values.
Abstrak
Proses konstruksi dalam proyek terkadang mengharuskan dibuat suatu lereng buatan yang dibuat dengan cara melakukan pemotongan pada suatu lereng alami pada suatu wilayah. Dalam perencanaan pembuatan lereng, perlu dilakukan analisis mengenai faktor keamanan lereng tersebut, sehingga dapat mencegah kemungkinan kegagalan lereng. Pada suatu proyek di Ciawi, Bogor, perlu dibangun dinding penahan tanah (DPT), sehingga diperlukan adanya proses pemotongan kontur dengan desain awal kemiringan lereng adalah 90° atau lereng tegak lurus, dengan ketinggian 12 m. Dari hasil analisis dengan Metode Fellenius, untuk lima kondisi kemungkinan ditemukan nilai faktor keamanan, yaitu kondisi tanpa pembebanan tambahan sebesar 0,86, dengan pembebanan tambahan sebesar 0,84, steady state seepage sebesar 0,60, sudden drawdown sebesar 0,61, dan gempa sebesar 0,72, diketahui bahwa lereng tidak memenuhi faktor keamanan menurut SNI 8460:2017 yaitu sebesar 1,25, akan tetapi proyek sudah rampung dan lereng tidak mengalami kegagalan. Hal ini diakibatkan karena dalam perhitungan faktor keamanan, dilakukan banyak asumsi, salah satunya adalah reduksi pada nilai kohesi (c) dan juga sudut geser (ϕ), sebagai asumsi bahwa lereng akan mengalami pembebanan jangka panjang sehingga kehilangan nilai kohesi dan sudut geser, sementara itu lereng diperuntukkan hanya untuk beberapa bulan konstruksi dan tidak menerima pembebanan berlebih, sehingga tidak mengalami reduksi pada nilai kohesi dan sudut geser.

Published: February 2024

Im folgenden Beitrag soll die Bedeutung von störungsspezifischen Konzepten für die Theoriebildung wie auch für die psychotherapeutische Praxis anhand von Persönlichkeitsstörungen dargestellt werden, und zwar insbesondere am Beispiel der narzisstischen Störungen und Borderline-Persönlichkeitsstrukturen. Bei diesen Störungsbildern steht, im Unterschied zu den neurotischen Störungen, nicht die Inkongruenz zwischen Selbst und organismischem Erleben im Vordergrund, sondern die Beeinträchtigung des Selbstkonzepts.
Zur Darstellung und Begründung narzisstischer Störungen und Borderline-Persönlichkeitsstrukturen, erscheint es daher notwendig, die Entwicklung des Selbst und die Ausbildung der Selbststrukturen aufzuzeigen. Ich greife dabei auf theoretische Konzepte der Selbstpsychologie, der Objektbeziehungstheorie sowie der empirischen Säuglingsforschung zurück, um im Lichte dieser Theorien und Erkenntnisse die theoretische Konzeption des Selbst im Rahmen des Personzentrierten Ansatzes zu diskutieren und weiterzuentwickeln. Es geht um die Topographie der Selbststruktur als Modell zur Darstellung und Begründung von Selbsterleben.

The concept of corporate conflict and alternative ways to resolve it in the Asia-Pacific countries
Authors: Rybka Oleg Sergeevich
Published: February 2024

The subject of this study is the concept of "corporate conflict", its problematic aspects when defining, signs, as well as alternative ways to resolve such conflicts in different countries of the Asia-Pacific region. The author examines many diverse approaches to the concept of "corporate conflict", based on the opinion of scientists from the Asia-Pacific region and draws conclusions based on the selected literature. The author also examines in detail alternative ways of dealing with corporate conflicts in such Asia-Pacific countries as the USA, China, Japan. The author highlights the types of alternative dispute resolution unknown to the legislation of the Russian Federation, such as mini-trial, common in the United States, and formal commercial mediation used in the PRC. Attention is also paid to alternative dispute resolution methods such as mediation, arbitration, ombudsman and the combination of mediation and arbitration.  The author uses such scientific research methods as description, analysis, synthesis, comparative legal method, sociological method. The scientific novelty of the study lies in the fact that it includes an analysis of existing alternative mechanisms for resolving corporate disputes in the law of the countries of the Asia-Pacific region. The author also identifies the signs and features of the concept of "alternative conflict" based on the research of a group of scientists from different countries and gives his own definition of this term, which is the most complete, and, in the author's opinion, takes into account all the features of this concept. The conducted research can help entrepreneurs understand the possibilities of out-of-court dispute resolution when doing business in the countries of the Asia-Pacific Region, and can also contribute to the scientific community to evaluate special types of alternative dispute resolution methods and consider the possibility of applying these methods in practice in the Russian Federation.

Published: February 2024

Background:

To date, there are few guidelines and studies to guide the timing of initiation of therapeutic anticoagulation (AC) after craniotomy. The goal of this study was to assess the timing, safety, and outcomes of patients following the administration of therapeutic AC after craniotomy.

Methods:

A retrospective case–control study was performed evaluating all craniotomy patients from August 2017 to July 2021. Cases were selected if they received therapeutic AC within ten days of craniotomy. Nineteen out of 1013 craniotomy patients met the inclusion criteria. Indications for therapeutic AC were diverse, including deep venous thrombosis, pulmonary embolism, dural venous sinus thrombosis, mechanical heart valve, and left ventricular thrombus.

Results:

The mean and median time to therapeutic AC were 5.35 and 5 days, respectively. Three patients developed intracerebral hemorrhage (ICH) that was stable on repeat imaging and did not require any surgical intervention or result in new neurologic deficits. There was no significant association between therapeutic AC and postoperative ICH (P = 0.067).

Conclusion:

This study demonstrated that the initiation of therapeutic AC in postoperative craniotomy patients from postoperative days 2 to 10 did not result in any major complications. A prospective study is warranted to clarify the indications and safety of therapeutic AC after craniotomy.
Electrochemical synthesis of cadmium chelates at sacrificial anode
Authors: Bala Kanchan , Singh Baljit
Published: February 2024

The synthesis of cadmium chelates through an electrochemical technique, involving the anodic oxidation of a sacrificial metallic electrode (cadmium) within an H-type cell, is reported. This process utilizes acetonitrile as a solvent with organic compounds containing abstractable hydrogen RH2 (nitroethane, 2-nitropropane, malononitrile and diethylmalonate) serving as the reactants. This study encompasses the coordination complexes of cadmium with ligands, 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen). The electrochemically synthesized products have been confirmed through various physical measurements, elemental analyses and infrared spectral studies. This one-step electrochemical technique is highly effective in obtaining metal complexes and their coordination complexes. The determination of current efficiency for these synthesized complexes serves to elucidate the underlying reaction mechanism.

Diffusion Limited Kinetics In Reactive Systems
Authors: Johnson Matthew S. , Mueller Joy N. , Daniels Craig , Najm Habib N. , Zador Judit
Published: February 2024

Proper representation of chemical kinetics is vital to understanding, modeling, and optimizing many important chemical processes. In liquid and surface phases, where diffusion is slow, the rate at which the reactants diffuse together limits the overall rate of many elementary reactions. Commonly, the textbook Smoluchowski theory is utilized to estimate effective rate coefficients in the liquid phase. On surfaces, modelers commonly resort to much more complex and expensive Kinetic Monte Carlo (KMC) simulations. Here we extend the Smoluchowski model to allow the diffusing species to undergo chemical reactions, and derive analytical formulae for the diffusion limited rate coefficients for 3D, 2D and 2D/3D interface cases. With these equations we are able to demonstrate that when species react faster than they diffuse they can react orders of magnitude faster than predicted by Smoluchowski theory, through what we term “the reactive transport effect.” We validate the derived steady state equations against particle Monte Carlo (PMC) simulations, KMC simulations and non-steady state solutions. Furthermore, using PMC and KMC simulations, we propose corrections that agree with all limits and the computed data for the 2D and 2D/3D interface steady state equations, accounting for unique limitations in the associated derived equations. Additionally, we derive equations to handle couplings between diffusion limited rate coefficients in reaction networks. We believe these equations should make it possible to run much more accurate mean-field simulations of liquids, surfaces, and liquid-surface interfaces accounting for diffusion limitations and the reactive transport effect.
Leveraging Temperature-Dependent (Electro)Chemical Kinetics for High-Throughput Flow Battery Characterization
Authors: Fell Eric , George Thomas , Jing Yan , Gordon Roy , Aziz Michael
Published: February 2024

The library of redox-active organics that are potential candidates for electrochemical energy storage in flow batteries is exceedingly vast, necessitating high-throughput characterization of molecular lifetimes. Demonstrated extremely stable chemistries require accurate yet rapid cell cycling tests, a demand often frustrated by time-denominated capacity fade mechanisms. We have developed a high-throughput setup for elevated temperature cycling of redox flow batteries, providing a new dimension in characterization parameter space to explore. We utilize it to evaluate capacity fade rates of aqueous redox-active organic molecules, as functions of temperature. We demonstrate Arrhenius-like behaviour in the temporal capacity fade rates of multiple flow battery electrolytes, permitting extrapolation to lower operating temperatures. Collectively, these results highlight the importance of accelerated decomposition protocols to expedite the screening process of candidate molecules for long lifetime flow batteries.
Diversification of 2,2’-Bipyridines and Azaheterocycles via Nucleophilic Displacement of Trimethylaminiums
Authors: Yang Jenny , King Ryan
Published: February 2024

Bipyridines and azaarenes are an important class of ligands that impart unique and tunable properties to transition metal complexes and catalysts. While some derivatives are commercially available, noncommercial analogues are often challenging to prepare and purify. Herein we report a general nucleophilic aromatic substitution reaction that converts cationic trimethylaminated bipyridines into a series of functionalized bipyridines. Our method showcases a series of C–O, C–S, and C–F bond forming reactions as well as a selective monodemethylation that converts the electron-deficient trimethylaminium to an electron-rich dimethylamine. The approach was further applied to diversification of pharmaceuticals and natural products, and was applied to the total synthesis of Graveolinine and the preparation of Graveolinine derivatives.

Published: February 2024

We propose using cocrystals as effective polarization matrices for triplet dynamic nuclear polarization (DNP) at room temperature. The polari-zation source can be uniformly doped into cocrystals formed through acid–acid, amide–amide, and acid–amide synthons. The dense-packing crystal structures, facilitated by multiple hydrogen bonding and – interactions, result in extended T1 relaxation times, enabling efficient polarization diffusion within the crystals. Our study demonstrates the successful polarization of a DNP-magnetic resonance imaging molecular probe, such as urea, within a cocrystal matrix at room temperature using triplet-DNP.

Authors: Liu Xiaowei
Published: February 2024

In a world of deepening globalization, although peace and development are the themes of the times, the international community is faced with common issues such as climate change, refugee immigration, the North-South gap and international finance problems, which are inseparable from all countries and regions, and the trends towards anti-globalization and cultural nationalism are also on the rise. The International Olympic Committee (IOC), as a major international organization, has chosen to address some of these issues through an approach of international sport participation, upholding the spirit of the Olympic Games and passing it on in the era of globalization. This paper will explore the IOC’s commitment to achieving the global goals of peace and truce, solidarity and harmony, the community of all human beings, as well as its own cultural transformation, by introducing refugee delegations to the Olympic Games to send a signal of concern to the world about refugee issues.

Published: February 2024

This paper provides a comprehensive review of leadership styles within the context of start-ups, exploring their effects on growth, innovation, and overall success. By carefully observing the delineation of leadership styles, including transformational, transactional, charismatic, situational, and laissez-faire, the review illuminates the unique attributes and implications each style holds for burgeoning businesses. Transformational leadership emerges as a crucial driver for innovation, emphasizing vision and collective drive. In contrast, transactional leadership offers operational efficiency but may risk long-term adaptability. Charismatic leaders, with their compelling personas, drive rapid growth, but centralization can pose challenges. With its inherent adaptability, situational leadership proves invaluable in the volatile start-up landscape, and laissez-faire leadership, promoting autonomy, demands careful balance to prevent directionlessness. The intricate relationship between leadership styles and business growth is explored in depth, underscoring that while leadership is a pivotal determinant, its efficacy intertwines with numerous variables, from market dynamics to team composition. One standout realization is the profound synergy between leadership and innovation, a lifeline for differentiation in the competitive start-up arena. Leadership’s role is thus not confined to mere administration; it shapes organizational culture, guiding innovation and strategic direction. The review emphasizes that effective start-up leadership is multifaceted, requiring foresight, adaptability, and a visionary outlook. As the entrepreneurial world continues to evolve, understanding and harnessing the nuances of leadership styles remains critical for sustained growth and success.

Published: February 2024

The Covid-19 pandemic has made it imperative to prioritize health standards in companies and public areas with a large number of people. Typically, officers oversee the usage of masks in public spaces; however, computer vision can be employed to facilitate this process. This study focuses on the detection of facemask usage utilizing the YOLO-v5 algorithm across various datasets and resolutions. Three datasets were employed: the face with mask dataset (M dataset), the synthetic dataset (S dataset), and the combined dataset (G dataset), with image resolutions of 320 pixels and 640 pixels, respectively. The objective of this study is to assess the accuracy of the YOLO-v5 algorithm in detecting whether an individual is wearing a mask or not. In addition, the algorithm was tested on a dataset comprising individuals wearing masks and a synthetic dataset. The training results indicate that higher resolutions lead to longer training times, but yield excellent prediction outcomes. The system test results demonstrate that face image detection using the YOLO-v5 method performs exceptionally well at a resolution of 640 pixels, achieving a detection rate of 99.2 percent for the G dataset, 98.5 percent for the S dataset, and 98.9 percent for the M dataset. These test results provide evidence that the YOLO-v5 algorithm is highly recommended for accurate detection of facemask usage.
