Authors: Yanthi Tri
Published: January 2025

Penelitian ini membahas tentang klausul non-kompetisi dalam perjanjian kerja sebagai alat perlindungan rahasia dagang perusahaan, dengan fokus pada efektivitas dan keabsahannya dari perspektif hukum. Dalam dunia bisnis yang semakin kompetitif, rahasia dagang memiliki nilai ekonomi yang signifikan dan oleh karena itu memerlukan perlindungan yang ketat. Salah satu cara yang digunakan perusahaan untuk melindungi informasi sensitif adalah dengan menetapkan klausul non-kompetisi dalam perjanjian kerja karyawan. Klausul ini membatasi karyawan untuk tidak bekerja di pesaing atau memulai usaha yang serupa setelah mereka meninggalkan perusahaan. Meskipun demikian, keberadaan klausul ini harus memenuhi beberapa syarat agar sah dan efektif, antara lain terbatas dalam hal waktu, ruang lingkup, dan wilayah serta disertai dengan kompensasi yang adil. Dalam tulisan ini juga dijelaskan tentang peraturan perundang-undangan yang mengatur perlindungan rahasia dagang di Indonesia, khususnya Undang-Undang Nomor 30 Tahun 2000 tentang Rahasia Dagang. Selanjutnya, pembahasan berfokus pada dua rumusan masalah utama: (1) keabsahan klausul non-kompetisi dalam perjanjian kerja berdasarkan peraturan perundang-undangan, dan (2) efektivitas klausul tersebut dalam melindungi rahasia dagang perusahaan. Melalui analisis mendalam, disimpulkan bahwa klausul non-kompetisi dapat menjadi alat yang efektif dalam melindungi rahasia dagang, dengan catatan bahwa klausul tersebut harus dirumuskan secara hati-hati untuk memastikan kesesuaiannya dengan hukum yang berlaku dan prinsip keadilan bagi pekerja. Tulisan ini memberikan wawasan yang lebih komprehensif mengenai tantangan dan peluang dalam penerapan klausul non-kompetisi serta implikasinya terhadap hubungan industrial dan hukum ketenagakerjaan.

TRANSFORMASI FOURIER, LANGSUNG, RIETVELD: PENENTUAN STRUKTUR KRISTAL OPTIMAL SEBAGAI MATERIAL PERTAHANAN
Authors: Sianipar Alexcandro , Talalu Lidya Ananda , Aritonang Sovian
Published: January 2025

Determining the optimal crystal structure is essential in the development of defense materials, as its crystal structure influences the physical and mechanical properties of a material. This study employs a mathematical approach to analyze crystal structures through three primary methods: Fourier Transformation, Direct Methods, and the Rietveld method. Fourier Transformation enables the analysis of diffraction data generated by the interaction of X-rays with atoms in a crystal, converting it into electron distribution to identify atomic positions. The Direct Method utilizes probabilistic phase relationships to accurately estimate atomic positions, even when diffraction data is incomplete. The Rietveld method, based on optimization, refines the crystal structure model by comparing experimental diffraction data with simulated results, minimizing differences between them. The analysis results show that the combination of these three methods effectively determines the optimal crystal structure. The implementation of these techniques is expected to support the selection of superior materials for defense applications

Exports play a strategic role in supporting the country's revenue. The oil and gas sector, as one of Indonesia's primary natural resources, contributes significantly to national economic growth. Indonesia's oil and gas production currently exhibits an unstable trend, influenced by the dynamics of global prices and demand. This research aims to forecast Indonesia's oil and gas export volume in 2025 using the Chebyshev extrapolation method. The Chebyshev extrapolation method is chosen due to its ability to produce more accurate predictions for data outside the available time range. The data used includes monthly export volumes of the oil and gas sector from 2019 to 2024. In the analysis, a fourth-degree Chebyshev polynomial is applied to project future export trends. The Mean Absolute Percentage Error (MAPE) for the Chebyshev extrapolation model is 12,10%. The forecasting results indicate an increase in monthly oil and gas exports in 2025, with the lowest value recorded in January at 1.373,70 and the peak export in December at 1.805,33. Overall, this prediction indicates the stability of oil and gas export volumes with a tendency towards an increasing trend compared to the previous year.

The assessment of the use of vehicles with different types of drive in car-sharing systems
Authors: Ewelina Sendek-Matysiak
Published: January 2025

One of the main challenges of contemporary transport policy is to reduce the share of individual means of transport in the structure of transport, i.e., to reduce the number of private cars used as the primary means of transportation. This issue is particularly important in urban areas, where congestion generates significant economic costs and poses specific risks to the environment and air quality, ultimately negatively affecting the health of residents. Over the past decades, many solutions have been developed to support the reduction of car traffic, most of which are implemented in urban areas, including short-term car rental services - car-sharing. As the popularity of such services grows, numerous scientific studies have been undertaken to analyze various social, environmental, or economic aspects related to the practical implementation of these systems. A niche area that still remains underexplored is research directly related to the vehicles that make up car-sharing fleets. Addressing this research gap, this article is dedicated to determining which vehicles, considering the type of propulsion used, are optimal for creating a car-sharing fleet based on, separately and collectively, economic, technical, and environmental criteria. To this end, an original procedure was proposed, taking into account the analysis of secondary data on car-sharing fleets in Poland, expert studies conducted among operators of these services, and mathematical analyses using multi-criteria decision support methods (point method of multi-criteria evaluation, MAJA). The study included vehicles with conventional, hybrid, and electric propulsion. Five vehicles of the same model and brand, each with a different type of propulsion, belonging to the most popular C-market segment in car-sharing systems in Poland, were considered. The analyses made it possible to identify the vehicles best suited to the needs of car-sharing in terms of technical, economic, and environmental criteria. The results indicate that under current conditions, considering all evaluation criteria simultaneously, an electric-powered vehicle is the optimal solution. When vehicles were evaluated from the perspective of one of the strategic objectives, plug-in hybrid vehicles dominated. Such vehicles proved to be the most advantageous solution, whether only economic or technical criteria were considered. Electric cars, followed by plug-in hybrid cars, are the best choice when decisions are evaluated from an environmental perspective. The proposed method serves as a decision-making guide for implementing or modernizing fleets in car-sharing systems, which can be used by car-sharing operators to organize their vehicle fleets, as well as by city authorities in selecting car-sharing service providers whose fleet meets their expectations.
Impact of different car-following models on estimating safety and emissions on signal-controlled intersections using microscopic simulations
Authors: Biszko Konrad , Oskarbski Jacek , Żarski Karol
Published: January 2025

This paper examines the influence of two selected car-following models on the outcomes of microscopic traffic simulations. The authors begin by reviewing the literature on the various traffic models, methods for estimating energy consumption, fuel use, and emissions. The authors discuss using surrogate safety measures derived from analysing vehicle trajectories in a microscopic traffic model to estimate safety levels. This paper also outlines the authors' approach to data acquisition and processing at the chosen test site. Most data are sourced from the city's Intelligent Transport System (ITS) services, including traffic flow volume, vehicle speed, and public transport travel times. The data gathered from Automatic Vehicle Location (AVL) systems was compared to manual travel time measurements. Depending on the analysed section Mean Average Error (MAE) ranging from 3 to 5 seconds was obtained, however, Mean Absolute Percentage Error (MAPE) ranged from 7.46% to 30.01%. The proposed method aims to evaluate the precision of the microscopic model in replicating real road networks and traffic based on available datasets. Two car-following models (CFM), Wiedemann 74 (W74), and Wiedemann 99 (W99) are chosen for further analysis. The models were validated using the GEH statistic and by comparing speed distributions. Both the models yielded satisfactory results. Different scenarios involving changes in traffic flow and to traffic signal configurations were analysed. While both W74 and W99 yielded satisfactory results, there were discernible disparities in the analyses. In general, W99 yields less favourable results, characterised by emissions, and delays compared to W74. Depending on the scenarios compared, the number of conflicts for W74 varied up to 56% (scenarios 2 and 4), and up to 78% for W99 (scenarios 1 and 4). The methodology presented by the authors can be used in future research to analyse various traffic control solutions concerning their impact on the environment and traffic safety. The observed differences underscore the importance of careful model selection and presented approach can serve as a foundation for developing guidelines for microscopic modelling and a multi-criteria approach to selecting the most effective implementation scenarios.
Modelling and analysis of selected platform dynamics issues of a land robot
Authors: Dziopa Zbigniew , Zuska Andrzej , Więckowski Dariusz
Published: January 2025

The research object is a land robot designed to perform special tasks. One of the robot's elements is a six-wheeled platform with independent suspension. The platform allows the robot to move on land and overcome obstacles. Any equipment enabling the robot to perform planned tasks can be mounted on it. If the implementation of the mission requires the platform to move in uneven terrain, external forces are generated resulting from the platform's wheels overcoming uneven road surfaces. Disturbances occurring in the system may negatively affect the measuring and actuating devices mounted on the platform. Actuator devices may also cause additional excitations. This may lead to disruptions in the process of the land robot carrying out its intended work. The aim of the work is to analyse selected dynamics issues with particular emphasis on the modal analysis of the land robot platform and, on this basis, to check the correctness of its design. In order to carry out the tasks set, a physical and mathematical model of the platform was developed. The energy method was used to derive the analytical relationships, which requires the determination of the kinetic energy, the potential energy, the dissipative Rayleigh function and external non-potential forces. A modal analysis was carried out to determine the dynamic parameters of the system and its susceptibility to the generated excitations was determined. The considerations carried out allow for the design of a structure that improves comfort for the actuating devices. Thanks to the developed model, it is possible to select the values and distribution of system parameters in such a way as to exclude the phenomenon of beating and resonance. In the general case, the robot's basic motion is coupled to the disturbances generated in the system. That's why the considerations carried out in this paper are so important, which enable the development of robot platform dynamics that minimize the impacts on the robot's realized fundamental motion.

Efficient and safe movement of trains on railway lines is assured by railway signalling systems. These systems assure safety of railway transport by preservation of dependencies. A significant fraction of dependencies is related to route setting, i.e., preparation of train travel through the specified running paths. The use of computer technology in modern systems allows for greater functionality and smaller physical devices dimension than older types of systems. This results in increased complexity of track layout and increased area of a single interlocking. Systems with considerable number of routes, over a thousand are becoming increasingly common. The research is concerned with the problem of describing route dependencies in computer-based interlocking configuration. During the research existing solutions have been analyzed and a method of describing route dependencies based on requirements of PKP PLK has been proposed. The proposed solution has been verified by functional testing of prototype interlocking. During the research, a formalism for describing the route has been devised, which allows for dependency realization by track layout independent computer program. In addition, during research algorithms for automatic verification of conflicting route exclusion correctness have been designed, which allows for reduction of effort required for verification of conflicting route exclusion function. The proposed method of describing route dependencies allows for simplification of interlocking design and for automation of application data preparation. The method of implementing dependencies also allows for automation of conflicting route exclusion function verification, which decreased the effort required for verification activities while maintaining the high-quality standards.

The aim of the analysis is to examine the impact of new railway stop openings within suburban railway network on changes in transport behaviors within their respective catchment areas. The study focuses on six railway stations: four located within the Kraków suburban railway network (malopolskie, Poland) and two on the Łódź suburban railway network (lodzkie, Poland). To achieve the stated objective, the spatial context and accessibility of the railway stations were examined, passenger exchange data at the stations were investigated, and surveys among passengers were conducted and analyzed. The selected railway stops were characterized in terms of their spatial location and characteristics, existing transport systems, and the level of integration with other transport modes. The study examined stations established during the development of suburban railway systems, launched at different times: concurrently with the entire railway connection launch and as densification of previously served networks. The limited number of objects included in the study does not allow for unequivocal conclusions on expected increase in transportation, but certainly, in the first two years following their launch, a monthly average increase of 4-6% can be anticipated. Research has confirmed that the most common rail passengers are former users of other means of public transport. The pattern of giving up cars in favor of the train was also confirmed. The outcomes confirm the justification for supplementing agglomeration railway systems with new stops, as this may contribute to a change in modal split. This change may not be noticeable in view of the usually considered large scale of the agglomeration, but on individual corridors in a micro scale it may have a very positive impact on the traffic situation and change the quality of travel. Results can be used to forecast changes in travel behaviors for planned railway stations and to determine their potential benefits.

Tax is one form of state revenue that contributes the largest percentage compared to other income sectors such as oil and gas (oil and gas) and non-oil and gas. The success of a country in collecting taxes from its citizens will certainly benefit the economic stability of the country concerned. Sustainability of state revenues from the tax sector is needed because tax revenues are the main source of state revenue and expenditure budget revenues. This research method is quantitative research, quantitative research can be interpreted as a research method based on the philosophy of positivism, used to examine a particular population or sample, data collection using research instruments, quantitative/statistical data analysis, with the aim of testing the established hypothesis. at the end of the output, it can be seen that the constants and variables of Tax Collection are statistically larger. At the constant which is 0.06 and the variable Tax Collection which is 0.011, both of which are below 0.05. The tax collection variable has a Sig value of 0.011 (0.05) and concludes that tax collection has a partial effect on tax arrears receipts. The Sig value shows that 0.011 is below 5% which indicates that more and more people are aware of paying tax arrears. The constant coefficient value of 4.143 with a positive sign indicates that when it is assumed that there is no income and religiosity, then the people of Pekanbaru City are actually already obedient in paying taxes. Given the figure of sig 0.006 (below 5%) it means that the basic potential of the Pekanbaru community is indeed obedient to paying taxes.

Bali has several institutions based on cultural values, traditions and customs. Tri Hita Karana is a basic concept used by indigenous people in Bali as a guide in living life. The concept of Tri Hita Karana is also a foundation in organizations, one of which is the Village Credit Institution (LPD) in Bali. The Village Credit Institution is an institution formed by the village that functions to manage village finances with the aim of improving welfare. The success of LPD cannot be separated from the ethical role of the leaders. This article aims to provide an understanding of the philosophy of Tri Hita Karana in ethical leadership from the perspective of the philosophy of science ontology, epistemology, and axiology.
