Strategi Pencegahan Fraud di Lingkungan Pelabuhan Indonesia

The port is the gateway to a country's economy, so the port must be clean from fraud. The purpose of this study is to determine the strategy developed by Pelabuhan Indonesia to prevent fraud. The method used in this research is qualitative method with a case study approach. The results and conclusions of this study are many studies on fraud prevention in the Indonesian port environment, even though Indonesian ports are one of the entry points for global trade. Therefore, Indonesian ports need an efficient fraud prevention system. The study findings show that Indonesian ports have implemented two fraud prevention strategies. The first strategy is strengthening governance within Pelindo, which includes: a) ratifying GCG guidelines; b) carrying out the signing of an integrity pact; c) gratuity control; d) a violation reporting system called "Pelindo Bersih"; e) socializing the implementation of corporate governance; and f) strengtheningPelindo'ss SMAP. The second strategy involves digitizing services such as Vessel Management System (VMS) and Vessel Traffic Service (VTS), as well as land ones such as Terminal Operating System (TOS), Multipurpose Terminal Operating System (MP-TOS), Car Terminal Operating System (CTOS), Autogate System, Single Truck Identification Data System (STID), Behandle Management System (BMS), and from the customer side such as e-Service developed into i-Hub to minimize national logistics costs, Lower the risk of fraud, and compete on a global scale.

Symmetry analysis for nonlinear fractional terminal system under $ w $-Hilfer fractional derivative in different weighted Banach spaces

<abstract><p>Our objective in this study is to investigate the behavior of a nonlinear terminal fractional system under $ w $-Hilfer fractional derivative in different weighted Banach spaces. We examine the system's dynamics and understand the effects of different weighted Banach spaces on the properties of solutions, including existence, uniqueness, stability, and symmetry. We derive the equivalent integral equations and employ the Schauder and Banach fixed point theorems. Additionally, we discuss three symmetric cases of the system to show how the choice of the weighted function $ w(\iota) $ impacts the solutions and their symmetry properties. We study the stability of the solutions in the Ulam sense to assess the robustness and reliability of these solutions under various conditions. Finally, to understand the system's behavior, we present an illustrative example with graphs of the symmetric cases.</p></abstract>

Analysis and Application of Practical Ability of Multimedia Technology in Art Education

Abstract With the development of multimedia technology, more and more colleges and universities apply network multimedia technology in art teaching to achieve the improvement of the art teaching effect. After analyzing the application scenarios of D2D, D2D technology is combined with social networks to create a teaching classroom where teachers and students can collaborate. A communication link is established in the network classroom to facilitate the sharing of art education content. Combine the network terminal caching system to improve the cache hit rate by caching multiple identical contents. Integrate network multimedia technology into art education and examine its contribution to education. The results show that the caching effect of multimedia technology is mainly reflected in four aspects: completeness, clarity, smoothness, and speed. When the number of caches reaches 12, the caching speed of the teaching content fluctuates in the range of 0.75-0.8. When the number of caches is less than 12, the caching fluency of the content is in the range of 0.85-0.9. This study provides a new direction to promote the reform of art education, which is conducive to improving the teaching effectiveness of art education and cultivating art talents.

Formulation and heuristic method for urban cold-chain logistics systems with path flexibility – The case of China

The focus of this paper is on achieving a win-win situation regarding the economic, environmental, and social impacts of the cold chain logistics terminal distribution system. This paper proposes three multi-objective models to investigate the above effects by incorporating soft time windows, heterogeneous fleets, and path flexibility, with defining the objectives of examining logistics costs, fuel consumption, carbon emissions, quality damage to perishable commodities, and customer satisfaction using six evaluation functions. To solve the proposed models, an efficient optimization framework is developed by combining domain operators with versatile multi-objective evolutionary algorithms (MOEA) to obtain Pareto solutions. Extensive experiments are conducted to test the validity of the concerned model and algorithms. The results demonstrate that: (1) the proposed algorithm is effective in solving the proposed model; (2) the proposed multi-path strategy can effectively improve the performance of cold-chain logistics systems compared to single-path strategies; (3) evaluation functions that assess customer satisfaction greatly affect the performance of cold-chain logistics systems; and (4) the trade-off relationship between the objectives should be investigated to define the model. The paper also provides valuable managerial insights for improving the efficiency and sustainability of cold-chain logistics operations.

Research on a Novel Terminal Water Supply System Based on the Diversion Process

The pipeline direct drinking water system (PDDWS) has emerged to ensure the quality of direct drinking water. Nevertheless, the existing literature suggests that the PDDWS suffers from inherent structural technological deficiencies, and various internal and external factors hinder its reliability, which raise concerns about the scientific and rational basis of the PDDWS. To address these issues, a new-type terminal differentiated water system (TDWS) is proposed to establish an efficient and health-oriented household water supply system. A water purifier is directly installed at the user’s terminal, and, due to its diversion process, differentiated water is provided, including direct drinking water, clean water and flushing water. Direct drinking water can be produced on demand, without secondary contamination. Clean water is also not stored, thus preventing microbial growth and ensuring superior water quality compared to tap water, suitable for kitchen usage. Flushing water is mixed with tap water for laundry, bathing and toilet flushing. Engineering verification has demonstrated that the quality of the direct drinking water and the clean water exceeds national standards. With the diversion process, the TDWS exhibits benefits related to health, the economy, applicability and environmental friendliness, and it can serve as a supplement and innovation for the PDDWS.

Autonomous flight termination system: The need for an international regulatory frame

Among the unmanned launch service providers, the autonomous flight termination concept is no longer an unknown actor around the table. The goal of these systems is to limit the consequences of the potential feared events caused by a launch vehicle malfunction by automatically terminating the flight of the vehicle in a safe manner, replacing the human component on the traditional flight termination decision in case of failure.Although some public and private players have already designed (and even flown) an autonomous flight termination system, the problem arises when looking into the safety standards that need to be to be applied to launch from different locations, which are highly dependent on the respective safety authorities.This paper aims at analysing the gap in the current launch safety policies and proposing the guidelines to be followed to widen the range of spaceports capable of hosting a launch vehicle with such a feature.

Energy, economic, and environmental (3E) performance assessment, comparison, and analysis of airport cargo terminal microgrid system under the islanded and grid-connected modes

Microgrids, which can be grid-connected or isolated, may experience dependability issues as a result of intermittent renewable energy. The implementation of a hybrid renewable energy system (HRES) could alleviate this problem but is still a challenging task because of its interference, uncertain, and unpredictable nature. Currently, the absence of comprehensive assessment impedes large-scale applications. In this study, a novel 3E assessment method-based complete quantitative assessment is suggested and inventively integrated with a newly proposed triangle evaluation scheme. Loads of an airport cargo terminal, which are used to test the assessment approach, are classified into critical and non-critical categories according to their necessity. The microgrid system flexibility is considered by the trade-off of non-critical loads. Results show that the assessment method is more intuitive in quantifying the system's performance. The Levelized Cost of Energy (LCOE) in the islanded mode is lower than the current electricity price (from 0.5407 to 0.5439 CNY/kWh) and the annual carbon emission is reduced to one-third of that in the grid-connected mode. Its flexibility can effectively reduce dependence on backup power generation, where the daily peak shedding increases from 217.88 kW to 555.04 kW and daily hours without charging from 6.7 h to 8.9 h. The carbon emission decreases by 32 % considering the impacts of the system flexibility. Besides, the critical distance exists when the LCOE exceeds the current market electricity price.

Joint scheduling optimization model for yard cranes and AGVs considering running routes

The escalation in global consumer demand has prompted the continual expansion of container throughput, which drives container terminals to bolster their production capacities. Globally, ports worldwide have been adopting automated equipment and embracing digital operational environments to reinforce their logistics system efficiency and curtail transportation costs. Enhancement of the efficiency of container transportation at automated terminals depends on terminal loading and unloading operations. The efficiency of these operations directly hinges on the automated mechanical equipment deployed at terminals. Consequently, optimization of resource allocation and production scheduling of loading and unloading equipment at terminals has become an essential and effective approach. In this regard, automated yard cranes, which are responsible for rear-end handling, and automated guided vehicles (AGVs), which transport containers between the yard and the terminal quay, have been proven indispensable. This paper principally delves into the scheduling optimization of mechanical equipment in automated container terminal yards, with a unique focus on the coordinated scheduling optimization of yard cranes and AGVs while also accounting for AGV path planning. This research centers on the automated container terminal yard system and the challenge in yard crane scheduling. This work also establishes a grid-based terminal network model and validates the model and algorithm using practical examples. Optimal solutions are obtained for the joint scheduling of yard cranes and AGVs, accompanied by strategies on rational AGV path selection. The findings provide valuable references and theoretical underpinnings for operational scheduling and enhancement of the efficiency in container transport in automated container terminal yards. Furthermore, these results facilitate the overall improvement of production efficiency at automated terminals and the reduction of operational costs, thus carrying theoretical and practical significance.

The Influence of Terminal Booking System (TBS), Yard Operation Plan (YOP), Turn Round Time (TRT) on Operational Effectiveness PT Pelindo Terimnal Peti Kemas Semarang

PT Pelindo Terminal Peti Kemas Semarang (TPKS) is a subholding of PT Pelindo that focuses on export and import container services. TPKS is one of the pioneers of the smart port concept in Indonesia, one of which is by implementing the Terminal Booking System (TBS) and Yard Plan to reduce Turn Round Time (TRT). However, in practice there are still many discrepancies between booking and gate-in hours, which have an impact on operational activities. The purpose of this study is to determine the effect of the Terminal Booking System, Yard Operation Plan, Turn Round Time both partially and simultaneously and to see the factors that most influence the operational effectiveness of TPKS. This study used a quantitative method of explanatory format with a population of planning, control and operational management divisions using total sampling. The results of this study indicate that there is a positive and significant influence between the Terminal Booking System, Yard Operation Plan, Turn Round Time both partially and simultaneously on the operational effectiveness of TPKS. Meanwhile, the most influential factor is the Turn Round Time variable. The conclusion is that there is a positive and significant influence between TBS, YOP, and TRT either partially or simultaneously on the operational effectiveness of TPKS. The researcher's suggestion for PT Pelindo TPKS is to be able to optimize loading and unloading activities and receiving delivery in domestic CY (Container Yard).

Improving terminal fire safety with minor impact on operational continuity using performancebased design

Bologna Airport is dealing with a significant increase in passenger flows. Even after the COVID-19 pandemic, traffic volume is rapidly growing and will soon exceed previous traffic records. Against this background, the airport has supported new infrastructure investments in order to both optimise existing terminal functional use and to comply with stringent fire safety requirements on terminal buildings, in line with new Italian airport safety legislation. In particular, Bologna Airport has planned a short-term investment specifically regarding the Terminal Smoke Management System, consisting of smoke vents and smoke extraction fans that work in coordination with fire detection systems and other fire suppression systems already installed into the building, and with the Terminal Fire Emergency Plan. For this kind of system, the Italian laws and standards set a basic prescriptive approach that simplifies the design phase with conservative solutions, with invasive, costly and time-consuming installations that are generally not compatible with operational continuity needs for terminal areas. As an alternative, a performance-based design approach is allowed for more customised solutions, focusing more closely on the design phase and terminal functional strategy. This case study shows how Bologna Airport implemented a performance-based design approach in order to minimise the impact of the new system installation throughout the terminal, optimising the engineering solutions with no constraints from the terminal functional flexibility point of view as well as saving over 75 per cent costs and construction time, compared to a traditional prescriptive approach.

Idiosinkrasi Manuskrip Mushaf Al-Qur'an di Desa Rejoagung Ngoro Jombang

The historical traces of the spread of Islam throughout the archipelago cannot be separated from the existence of ancient manuscripts, which are one of Indonesia's assets. This paper discusses the study of manuscripts in the form of mushafs of the Qur'an in a village in Jombang district, namely Rejoagung Village. The problem that will be answered in this article is regarding the physical characteristics of the manuscripts of the Al-Qur'an in Rejoagung Village and the idiosyncratic aspects of their textology. Some of the things that the author will examine are the forms of rasm, dabt, and the verse numbering system. The method used is the single manuscript method with critical editions in the study of ancient manuscripts. The result of this research is that this manuscript has a different idiosyncratic style from the Mushaf Al-Qur'an manuscripts in Indonesia. Rasm used is a mixture of usmani and imla'i. The verse termination system does not adhere to a Kufah school of thought, which is familiar in the copying of the Qur'an in the archipelago. This shows that the copyist applied idiosyncrasy in the process of copying. Follow-up research is needed to obtain a description of the different patterns of the process of copying the Al-Qur'an mushaf from various ancient manuscripts spread across Nusantara.

Antenna Systems with Wide-Angle Mechanoelectrical Beam Steering

Introduction. The active development of satellite communication networks determines the need for new antenna systems for ground terminals. The Sphere Federal program implies the commissioning of new satellite constellations for communication and remote sensing of the Earth. The Skif (providing broadband Internet access) and Express-RV (providing the Internet and communications for Arctic) satellite constellations are not geostationary, thus requiring constant satellite tracking even for stationary terminals. Deflecting structures operating on the principle of quasi-optical beam control make it possible to develop scanning antenna systems for organizing continuous satellite communications. Aim. Investigation of various types of dielectric structures for radiation pattern deflection and scanning antenna systems on their basis, as well as identification of a configuration with improved characteristics compared to the ideal structure in the shape of a dielectric wedge. Materials and methods. Mathematical modeling, electrodynamic modeling using CAD by the finite element method and the finite integration method, as well as an experimental study of an antenna system prototype in an anechoicchamber by measuring methods in the far-field and near-field of the antenna. Results. Electrodynamic simulation was carried out for three types of dielectric structures, analogues of a dielectric wedge, including a structure assembled from various dielectrics of fixed sizes with different dielectric constants; a structure of triangular dielectric plates; and a perforated dielectric structure. In addition, scanning antenna systems based on the presented configurations were analyzed. Radiation patterns were obtained for all structural types for various rotation angles of the deflecting systems. The structure assembled from various dielectrics of fixed sizes with different dielectric constants was found to possess the most optimal characteristics. This structure was used to develop a model for experimental confirmation of the conducted electrodynamic simulation. The maximum tilt angle of the radiation pattern was about 60°, the decrease in the directivity relative to the maximum value was 6 dB; for tilt angles up to 55°, the directivity degradation did not exceed 4 dB, the level of the side lobes did not exceed –12 dB (calculated) and –14 dB (measured). Conclusion. The results of studies into various types of structures for quasi-optical beam control of the radiation pattern show the possibility of using these configurations when creating low-profile antenna systems with wide-angle mechanoelectric scanning for organizing satellite communications for both mobile and stationary consumers using medium earth orbit spacecrafts.

With the rapid development of the economy, the power supply has also shown an increasing trend year by year, and many loopholes and hidden dangers have emerged during the operation of the power grid. The power grid may be subject to malicious attacks, such as hacker attacks, power theft, etc. This may lead to security risks such as power grid system paralysis and information leakage. In order to ensure the quality of power supply, it is necessary to optimize the distribution of electricity and improve power supply efficiency. This article pointed out the security performance issues of power Internet of Things (IoT) terminals and analyzed the design and implementation of a vulnerability mining system for power IoT terminals based on a fuzzy mathematical model simulation platform. This article used a fuzzy mathematical model to quantitatively evaluate the security performance of power IoT terminals, providing an effective theoretical basis for vulnerability mining. Based on the analysis of vulnerability mining technology classification and vulnerability attack process, this article characterizes vulnerability parameters through fuzzy mapping. Based on the collected vulnerability data and the online and device status of power IoT terminals, fuzzy logic inference is used to determine and mine potential vulnerability issues in power IoT terminals.

The fuzzy mathematical model can reduce the vulnerability risk level of the power IoT simulation platform system, and the time required for vulnerability mining was reduced; the time was reduced by 0.48 seconds, and the speed of vulnerability mining was improved. Fuzzy mathematical models can promote the development of the power industry, which provides strong support for the security protection of power IoT terminals.

Thermodynamic assessment of the Cr–Mo–Si ternary system

Based on the experimental isothermal sections at 1000 and 1200 °C and the liquidus projection from the measurements by the present authors, the Cr–Mo–Si ternary system is thermodynamically assessed using the CALculation of PHAse Diagram method (CALPHAD). The parameters of the thermodynamic descriptions of all the phases in the Cr–Mo–Si ternary system are optimized on the basis of the reported thermodynamic data and the constitution models of the Cr–Mo, the Cr–Si and the Mo–Si terminal binary systems. Two solution phases, liquid and bcc_A2, were described as substitutional solutions. The intermetallic phases, CrSi, CrSi2 and MoSi2, were modeled by two sublattices, (Cr,Mo):Si, (Cr,Mo):Si2 and (Mo,Cr):Si2, respectively, while βCr5Si3 was modeled by three sublattices (Cr,Mo,Si)2:(Cr,Si)3:Cr3. Cr3Si and Mo3Si have the same crystal structure (cP8, Pm-3n) and present a continuous intermetallic phase M3Si with the two sublattice model (Cr,Mo,Si)3:(Cr,Si)1. Similarly, αCr5Si3 and Mo5Si3 with the same crystal structure (tI32, I4/mcm) form a continuous intermetallic phase M5Si3 with the three sublattice model (Cr,Mo)4:(Cr,Mo,Si)1:(Mo,Si)3. Since the very small solubilities of Cr and Mo, the Diamond-Si phase was treated as a pure element phase. Using the current optimized parameters, the isothermal sections, the liquidus projection and the reaction sequence chart are calculated. The comparison between the calculated results and the experimental investigations, including the isothermal sections, the liquidus projection, and the solidification processes of the as cast alloys, shows that the present calculation can well reproduce the experimental equilibria. The present modeling can finely describe the experimental information of the Cr–Mo–Si ternary system.

Approximate time optimal control by deep neural networks trained with numerically obtained optimal trajectories

AbstractThis paper focuses on online time optimal control of nonlinear systems. This is achieved by approximating the results of time optimal control problems (TOCP) with deep neural networks (DNN) depending on the initial and terminal system state. In general, solving a TOCP for nonlinear systems is a computationally challenging task. Especially in the context of time optimal nonlinear model predictive control (TMPC) with hard real time constraints successful termination of a TOCP within sample times suitable for controlling mechanical systems cannot be guaranteed. Therefore, our approach is to train three DNNs with different aspects of numerical solutions of TOCPs with random initial and terminal state. These networks can then be used to approximate the TMPC by a one step model predictive control scheme with a significantly simpler structure and decreased calculation time. In order to verify this procedure by simulation, it is applied to a prove of concept example as well as the model of an industrial robot.
