Pengelolaan Pegawai Honorer Pemerintah Daerah Daerah Istimewa Yogyakarta
Authors: Widayat Wahyu
Published: January 2023

Untuk mewujudkan tujuan nasional sebagaimana termaktub dalam pembukaan Undang-Undang Dasar 1945 dibutuhkan Aparatur Sipil Negara (ASN) tidak hanya dari sisi kwalitas saja tetapi juga dari sisi kuantitas atau pemenuhan jumlahnya juga akan mempengaruhi baik buruknya pelayanan kepada masyarakat.  Untuk mewujudkan tujuan nasional tersebut ASN diberikan tugas selain sebagai pelaksana kebijakan publik juga harus memberikan pelayanan publik yang profesional dan berkualitas. Pelaksanaan kebijakan publik yang dijalankan ASN pada setiap organisasi perangkat daerah idealnya dengan mempertimbangkan analisis kebutuhan dan beban kerja agar tujuan organisasi yang ditetapkan dapat terlaksana. Kebutuhan ASN yang ideal di Pemda DIY ini ditetapkan sejumlah 16.200 pegawai ASN, tetapi realitas yang ada per Desember 2022 jumlah ASN yang ada hanya sejumlah 10.137 orang. Kekurangan jumlah pegawai ASN tersebut antara lain disebabkan jumlah ASN yang pensiun setiap tahun sekitar 600-700 orang tidak sebanding dengan jumlah rekrutmen ASN baru serta adanya moratorium rekrutmen ASN formasi 2020 dan 2021. Dengan adanya kekurangan sekitar 5.000 pegawai ASN tersebut, agar tidak menghambat pelayanan kepada masyarakat Pemda DIY mengisinya dengan rekrutmen pegawai non ASN (tenaga bantu) sebanyak 3.410 orang. Namun tanggal 31 Mei 2022 dan 22 Juli 2022 Menteri Pendayagunaan Aparatur Negara dan Reformasi Birokrasi mengeluarkan surat edaran yang mengamanatkan Pemerintah Daerah melakukan pemetaan Pegawai Non ASN dan bagi yang memenuhi syarat untuk diberikan kesempatan mengikuti seleksi ASN serta menghapuskan status kepegawaian selain PNS dan PPPK.  Adanya surat edaran tersebut tentunya perlu ada kebijakan dari Pemda DIY untuk mengatur dan mengelola pegawai non ASN selain untuk meningkatkan pelayanan publik tetapi juga untuk memberikan paying hukum terkait status pegawai non ASN itu sendiri.
La administración pública y la interculturalidad en pueblos originarios del Perú, en tiempos de COVID-19. Artículo de revisión
Authors: Choccata Cruz Ernestina Andrea , Villanueva Figueroa Rosa Elvira
Published: January 2023

La investigación tuvo como objetivo, el análisis de la práctica de la interculturalidad en la administración pública peruana en contextos de comunidades originarias como son los Quechuas, Aymaras, Shipibos y otros, en tiempos de la COVID-19; donde los pobladores de las culturas originarias identifican a un Estado que para ellos los discrimina, se sienten abandonados porque los servicios de salud y educación que reciben de las instituciones públicas y privadas es solo en lengua castellana, a falta de conocimiento de lenguas originarias por el personal de atención. Considerando los aportes de Méndez Reyes (2021) y Finol Romero (2021), los contextos interculturales demandan la práctica del pensamiento decolonial que incorpora en forma efectiva la cultura, la política y valores de los pueblos originarios; así mismo, la implementación de la calidad de servicio en un modelo de gobierno abierto. El método utilizado fue la revisión sistemática de acuerdo a los procedimientos sugeridos del modelo PRISMA. Se consultó 130 artículos-documentos de investigación y la selección de 70 artículos – documentos en base a los criterios de inclusión y exclusión del método PRISMA para sustentar el análisis crítico reflexivo de la temática a través de fundamentos, comparaciones y contextualizaciones en diferentes espacios del Perú, enmarcado en un Estado de derecho con instituciones que tienen la finalidad de solucionar la problemática nacional. Los resultados evidenciaron que la interculturalidad está avalada por leyes, directivas, ordenanzas municipales; sin embargo, a la fecha no se logra la implementación requerida en contextos de los pueblos originarios. La conclusión más relevante consiste en que la administración pública en el Perú no aplica la normatividad vigente de interculturalidad en tiempos de la COVID-19 y la población originaria demanda políticas públicas que incluyan servicios bilingües en un Perú pluricultural-multilingüe.

Inovasi Pembelajaran Matematika Dalam Implementasi Kurikulum Merdeka Di SMKN 1 Surakarta Sebagai Sekolah Pusat Keunggulan
Authors: Wisnu Hapsari Naomi Tri Mada
Published: January 2023

Sebagai pendidik, guru memiliki tanggung jawab besar terkait dengan kegiatan pembelajaran dan hasil belajar siswa terhadap materi yang disampaikan mengingat kemampuan dasar siswa terhadap materi belajar. Siswa Indonesia membutuhkan penguatan literasi dan numerasi. Hal ini berangkat dari fakta bahwa beragam survei di tingkat nasional dan internasional secara konsisten, dari tahun ke tahun, menunjukkan kedua bidang tersebut tidak mengalami peningkatan signifikan bahkan cenderung menurun. Kondisi ini terjadi karena proses pembelajaran di satuan pendidikan mengabaikan literasi dan numerasi sebagai dasar berpikir. Kondisi ini diperparah dengan pandemi Covid-19 yang memaksa siswa belajar dari rumah. Ketidaksiapan guru dalam mengajar dan minimnya sarana-prasarana pendukung mengakibatkan kegiatan pembelajaran terganggu. Survei Kementerian Pendidikan dan Kebudayaan mengungkap bahwa 67,11% guru mengalami kendala dalam mengoperasikan perangkat digital. Di lain sisi, 88,7% siswa kekurangan fasilitas pendukung seperti laptop, listrik, jaringan internet, dan gawai. Dampaknya, siswa tidak konsentrasi dalam belajar (51,1%). Menurut survei Komisi Perlindungan Anak Indonesia, 76,7% siswa tidak suka belajar dari rumah. Sebab, menurut pengakuan 37,1% siswa, mereka merasa kurang istirahat dan kelelahan karena mengerjakan tugas semua mata pelajaran. Dampak fatal akhirnya terjadi: siswa mengalami penurunan kemampuan belajar (learning loss).
Tinjauan Hak Asasi Manusia terkait Hak Atas Perlakuan yang Adil dan Layak dalam Hubungan Kerja
Authors: Rustam Martha Hasanah , Handoko Duwi
Published: January 2023

Masalah pokok dalam kajian ini adalah: Bagaimanakah pemenuhan norma hukum terkait setiap orang berhak untuk bekerja serta mendapat imbalan dan perlakuan yang adil dan layak dalam hubungan kerja? Jenis penelitian ini adalah penelitian hukum normatif yang khusus membahas tentang hak untuk bekerja serta mendapat imbalan dan perlakuan yang adil dan layak dalam hubungan kerja. Pasal 28D ayat (2) Undang-Undang Dasar Tahun 1945 menyatakan bahwa setiap orang berhak untuk bekerja serta mendapat imbalan dan perlakuan yang adil dan layak dalam hubungan kerja. Hanya saja untuk menyamakan apa yang sudah diatur dengan ketentuan tersebut dengan praktik di lapangan bukan suatu perkara yang mudah karena kejahatan dalam dunia tenaga kerja di Indonesia masih terjadi dan bahkan hal tersebut diketahui oleh aparat penegak hukum yang terkesan tidak peduli terhadap hal tersebut. Contoh kasus dugaan perbudakan buruh kuali merupakan bukti nyata atas hal ini dengan substansi berupa pekerja selama bekerja tidak diberi gaji, dipukuli apabila bekerja tidak mencapai target, mendapatkan makanan basi, dan tidak adanya alat-alat keselamatan kerja selama melakukan pekerjaan. Oleh karena itu, semua lapisan masyarakat sebaiknya melakukan pengawasan terhadap pabrik-pabrik yang bersifat tertutup dengan lingkungan sekitar dan Dinas Tenaga Kerja seharusnya melakukan pengawasan yang benar-benar dilaksanakan sesuai dengan tugas pokok dan fungsinya dalam menjamin terciptanya hak atas perlakuan yang adil dan layak dalam hubungan kerja. Hal ini dirasa penting karena selama ini pengawasan yang dilakukan tidak menyentuh terhadap substansi yang diawasi tetapi lebih kepada hubungan bisnis antara pengawas dengan pemberi kerja.

Le profil hétérogène des identités linguistiques des apprentis de portugais brésilien langue et culture d'origine (PLCO) en Suisse nous amène à nous interroger sur les usages des langues du contexte, notamment, du français langue de scolarisation dans l'enseignement du portugais. Une des préoccupations des enseignants de PLCO est de savoir comment transférer les connaissances acquises dans ces langues aux connaissances nécessaires au développement de la langue d'origine (LCO).  Dans cette contribution, nous présenterons une expérience d'enseignement d'une séquence didactique du genre oral présentation de soi dans laquelle il a été possible d'identifier l'alternance entre LCO et la langue de scolarisation dans les situations d'enseignement proposées à 8 élèves entre 5 à 12 ans dans une école brésilienne située à Genève-Suisse. Le fondement théorique qui guide notre proposition s'inscrit dans la perspective de l'ingénierie didactique notamment dans le  domaine de la didactique des langues ayant pour bases les concepts fondamentaux suivants : dispositif et séquence didactiques et capacités linguistiques (DOLZ & SCHNEUWLY 2009 ; SILVA-HARDMEYER, 2020) ; gestes didactiques des enseignants (SILVA, 2013 ; SILVA-HARDMEYER, 2017) ; approche plurilingue, transfert et alternance des langues dans l'enseignement (LEOPOLDOFF MARTIN, & AEBY DAGHE, 2018 ; NOYAU, 2014 ; AEBY DAGHÉ ET POGRANOVA, sous presse)

TRAFFIC MANAGEMENT SYSTEM BASED ON BLOCKCHAIN TECHNOLOGY AND INTERNET OF THINGS
Authors:   Don State Technical University, Aohua Guo
Published: January 2023

Blockchain is undergoing rapid development and has revolutionary potential applications in Intelligent Transportation Systems (ITS). Blockchain can be used to create a secure, reliable and decentralised autonomous system, creating the best use of legacy infrastructure and resources. One of the most important issues is the security issues caused by the evolution of ITS towards centralisation. Fast-growing technologies, including the Internet of Things (IoT) and cloud computing, enable most data processing, analysis and decision-making by centralised systems. With the continuous development of the Internet of Things, all kinds of smart systems are rapidly evolving to make life safer. Like many other industries, transport has entered a period of rapid change. The Intelligent Transport System is one of the fastest growing areas of smart systems, which is expected to improve road safety, alleviate traffic congestion and increase fuel efficiency. The main functions of an intelligent transport system are as follows: real-time monitoring of road conditions in specific areas, locating traffic accidents (crashes) in specific areas, dynamic monitoring and managing the continuous use of public transport services, which can lead to changes in vehicle traffic. In this paper, the above-mentioned functionality of an intelligent transport system will be used as basic modelling scenarios for the design and implementation of an intelligent transport system based on the Internet of Things and blockchain – both of which have the inherent characteristics of distributed technology – combining sensor nodes of the Internet of Things and distributed registry technology, to record changes in intelligent transport systems and create a credit token mechanism for op The intelligent transport system described in this paper is intended to be used only as a pilot project, subject to the conditions as shown in the simulated scenario. In real-world traffic scenarios, it may produce more complex system and data security issues, which will be described and analysed in detail in the article. An intelligent traffic system is a complex intelligent system; it can significantly change and reinvent the wheel for traffic conditions. Based on the system development discussed in this article, there are many more requirements and issues that need to be addressed in the future. Such topics will be covered in detail in our subsequent studies.
DELAYS OF TRAFFIC MANAGEMENT AT AN UNREGULATED PEDESTRIAN INTERSECTION WITH A DEDICATED LANE

The purpose of designing dedicated lanes for ground public transport is to reduce travel time and create the most comfortable conditions for users (passengers) compared to personal cars or other modes of transport. One of the design problems is the presence of right turns and pedestrian crossings on the route, which can largely determine the speed of ground public transport vehicles that differ from the designed one. There are three typical design schemes for right turns in the presence of a dedicated lane: traffic light regulation of the organization of the right turn; uncontrolled intersection, free from possible delays; uncontrolled intersection in the organization of pedestrian traffic, which ultimately determines the time delays of the ground public transport when vehicles are located in a dedicated lane, waiting for an acceptable headway between pedestrians. Traffic rules of most countries of the world provide for the highest priority for pedestrian traffic, including on uncontrolled pedestrian crossings. This situation increases the level of safety and service for pedestrians, but at the same time reduces the level of service of road for traffic flow. The article presents a methodology for assessing the impact of pedestrians on vehicle delays at an unregulated intersection with a dedicated lane for vehicles based on a probabilistic model. The simulation results showed that the discrepancies between the values of the model and the observed delays do not exceed 22% when the pedestrian traffic intensity is less than 1500 ped/h. Based on the results obtained, recommendations are proposed to minimize the delay of vehicles at unregulated intersections, including the ground public transport vehicles on a dedicated lane.
THE MAIN APPROACHES TO EVALUATING THE EFFECTIVENESS OF APPLYING THE RISK ANALYSIS AND MANAGEMENT METHODOLOGY AT ENERGY COMPANY
Authors:   Moscow Technical University of Communication and Informatics, Jahed Rahmani
Published: January 2023

At present, it is difficult to imagine the provision of any global services without the introduction of information and communication technologies. The energy company of the Islamic Republic of Iran is territorially distributed, and without a corporate information and telecommunications network, it would cease to exist. In a geographically distributed company on 1,648,195 sq.km, there are several hundred access points and several thousand users of the corporate information and telecommunications network and, therefore, it is very important to understand the possible risks, their assessment and management. In such large geographically distributed corporate information and telecommunications networks with high load, for the use of big data, you need to have a complete picture of risks in order to develop risk models. Without a picture of possible risks, it is impossible to build scenarios for various negative and emergency situations. If we consider the probability of a negative event occurring in the corporate information and telecommunications network as a risk, then its definition, analysis and taking measures to minimize the negative consequences is called risk management. One of the main properties of the risks of a corporate information and telecommunications network is their uncertainty. A geographically distributed corporate network is highly exposed to external factors that can directly affect the quality of its functioning. The occurrence of such situations is difficult to predict.

Data storage systems designed for storing large multidimensional arrays of information, functioning in conditions of destructive influences of an attacker and the environment, are considered. One of the most urgent tasks for such systems is the organization of secure data storage, and taking into account such operating conditions - ensuring their integrity. Ensuring data integrity is a difficult task, due to its complexity, as it includes both recovery and data integrity control. One of the well-known and widely used methods of data integrity control is the use of cryptographic methods, in particular, the hashing function. However, despite the widespread use of hash functions, they have been very little researched, and practical proposals for their use are very few and are characterized by a number of disadvantages associated with the need to introduce a high redundancy of control information. In the context of limitations on the existing resource of data storage systems, this can lead to a decrease in the probability of completing the task of their functioning, or even to its failure. A generalized method is proposed, the use of which will reduce the amount of introduced redundancy when monitoring the integrity of information in data storage systems, based on the use of cryptographic hash functions, a distinctive feature of which is the use of rules for constructing error-resistant codes. In addition, the developed method provides the data integrity control procedure with a new property: the ability to control the integrity of not only the data to be protected, but also the reference hash codes themselves. Calculated data of the required volume of the introduced redundancy are obtained when monitoring the data integrity in existing storage systems using the developed method.

To study complex systems, which include communication systems, both analytical and simulation modeling are used. Recently, simulation modeling has become widespread, which is becoming one of the most powerful analysis and synthesis tools used by specialists in the study and design of complex systems. However, traditional simulation modeling usually has a number of difficulties that arise from trying to represent processes in real systems in greater detail. At the same time, there is currently a tendency in modeling to improve the accuracy and adequacy of the created models. The answer to this requirement is the emergence of agent-based simulation. The aim of the article is to show the possibility and feasibility of using this rather new direction of modeling for the study of a special purpose communication system (SPCS). SPCS as an object of modeling is a rather complex system characterized by many parameters, and an attempt to improve some characteristics can and often leads to deterioration of other characteristics of this system. The work discusses the construction of a model of technical support for the SPCS based on the agent-based approach. The proposed approach to the construction of such a model, in contrast to the well-known approaches to the construction of simulation models, allows you to study the system "bottom-up". The developed model provides an opportunity to assess the quality of functioning of the SPCS taking into account the performance indicators of its elements, presented in the form of individual interacting agents, as well as a variety of random factors. The article deals with the application of the agent-based approach to modeling the technical support of the SPCS. The formulations of the problems of analysis and synthesis of SPCS are formulated. The composition of the components and the structure of the agent model are discussed. The aspects of the implementation of the agent-based model in the AnyLogic tool environment and the possibility of conducting experiments using this model are demonstrated. It is shown that the agent-based model of the technical support of the SPCS is universal for systems that implement similar functions. It allows simulating, setting and changing many network characteristics in a wide range, as well as determining the coefficient of technical availability of this system.

At present, the discovery of deterministic chaos is one of the significant subjects of research in various fields of science. In this work, deterministic chaos considered as a sequence with specific properties, which is used to transmit information in a stegosystem. The efficiency of the algorithm for steganographic embedding and extraction of digital information into audio containers by the method of spreading the spectrum using chaotic signals is analyzed. The spread spectrum method is characterized by the presence of a large number of errors on the receiving side when used in the classical version, without the original audio, i.e. there was no possibility of blind extraction. Errors arising when transmitting an audio signal over a communication channel made it impossible to extract the embedded information correctly. It proposed to use an algorithm that increases the efficiency of information signal extraction on the receiving side. The efficiency of the method is estimated by the amount of distortion in the original audio and by the reliability of extracted information, which is characterized by the value of the error probability. It showed that to extract embedded data with high reliability from stegoaudio, one should use an adaptive filtering algorithm - thresholding using discrete wavelet transform (DWT). The best filtering method, using various orthogonal mother wavelets (Haar, Daubechies, and Symlet) at different levels of signal decomposition, was determined. In the course of this study, recommendations were made on the use of mother wavelets, and was given preference to Daubechies and Symlet wavelets. Requirements for the numerical values of the embedding parameters and the parameters of the generators of chaotic processes used to expand the spectrum formulated.

Introduction: The discussion of partial and full electrification in the aviation community has now moved beyond discussions to the creation of the first prototypes. The speed of popularization of ideas about the need for an early transition to electrified aircraft raises concerns because there are a number of fundamental difficulties of transition to electrification, which are almost not discussed, in particular – the lack of weight reduction of the aircraft in flight. Research Objective: The purpose of the study is to determine a possible scenario of operation and design features of an electrified aircraft that uses batteries as an energy source for flight, considering the design and operational limitations and features. Results: Possible structural arrangements for the placement of batteries in the airframe design, considering the design, technological and operational constraints, are proposed. Described the fundamental disadvantage of electrified aircraft – the constancy of mass during flight. We propose options to ensure the reduction of the mass of the aircraft during flight as energy is consumed. The concept of a multistage airplane is proposed and a possible scenario of its operation is described. Practical relevance: The obtained knowledge can be useful for further research in the field of electrification of aviation, both in terms of theoretical research and in terms of the formation of conceptual and design solutions in the early stages of design. Discussion: The results allow us to conclude about the high degree of complexity and innovativeness of the required transformation of aircraft complexes when including a fully electrified aircraft. This entails changes not only in the design of the airframe, but also in the scenario of its operation and in the regulatory documents governing flight safety. Thus, it is necessary to further accurately establish the boundaries of admissibility of such solutions and determine an algorithm for assessing their economic efficiency, considering the impact on the environment.

Introduction: the paper considers the process of developing a simulation model of wireless broadband access of the 802.16 standard using Network Simulation 2. This approach allows you to quickly build the required network model using the OTcl scripting language without having to delve into the structure of the compiled part of ns-2. If modification or addition of the compiled part is necessary, this can be done by adding (or changing) the C++ code and recompiling the system. The only drawback of this approach is the difficulties in studying the system and debugging programs (models) arising from the use of two languages. The purpose of the study: In the work using the NS-2 simulator, it was necessary to identify the capabilities of various wireless broadband access standards, to conduct both analysis and comparison. Results: In order to realize the purpose of the study, a simulation modeling process was carried out. Based on the experiment, a decrease in packet loss and delay time was revealed when using the 802.16 standard. compared to other wireless broadband access standards. Practical significance: the use of this model in the design of wireless networks makes it possible to increase the efficiency of data transmission. Discussion: As a further study, a detailed consideration of the impact of modern data transmission protocols using a simulation model is required.

Introduction. The existing information security management in information systems is a set of informal verbal models. They make it possible to determine a variety of measures but cannot conduct numerical assessments – to compare alternative strategies according to the introduced criterion, to numerically record changes in the level of information security, to perform mathematically justified optimization of control actions. Purpose: The purpose of the study is to substantiate the possibility of using numerical estimates in information security management. Methods: The search for alternative methods of modeling information security management processes begins with the modeling object classification. The modeling object (the information security management process) is considered as a complex system having irremediable uncertainty. A method using fuzzy algorithms can be classified as one of the possible methods in modeling such objects. Fuzzy algorithms are most widely used when modeling technical control systems, but this method potential allows us to hope for positive results when modeling more complex processes. The article offers an example of using fuzzy modeling algorithms based on Mamdani rules of inference algorithms for creating an information security management system model of an information system. Results: The sensitivity, continuity and qualitative adequacy of the described model are substantiated, the possibility of operational tracking of the influence of destabilizing influences on the level of information security in the information system using a numerical metric is shown. Practical relevance: The use of the proposed methods opens up the possibility of building an automatic information security management system of an information system.

The growing demand for portable computing devices leads to new electronic systems fulfilling the requirements for the low power dissipation in the chip. Although, reduction of supply voltage is one of the most effective techniques of decreasing the power consumption in digital CMOS VLSI circuits it results in chip throughput degradation. This paper presents three versions of the Inserting Idle Operation with Interchanging heuristic algorithm, namely simple IIOI, MAximal RELativity (MAREL) and UNIform LOad (UNILO). They are applied to the high-level synthesis of CMOS VLSI circuits with power reduction. Comparison of the obtained results for the chosen set of benchmarks show the different levels of power reduction obtained by different algorithms applied. For different benchmarks the power reduction reaches up to 15%, and up to 68% with extending latency by 50%.

Ultra wideband (UWB) technology has obtained lots of attention as a strong candidate for short range indoor wireless communication because of low power consumption, low cost implementation and the robustness against multipath fading. It uses trains of short pulses which widely spread the signal energy in frequency domain. Since such large bandwidth can cause interference with other narrow band communication systems, the federal communications commission (FCC) has restricted not only the frequency region from 3.1GHz to 10.6GHz but also the transmission power level for commercial use of UWB systems. The effects of timing jitter on time hopping binary phase shift keying (TH-BPSK) UWB systems applying the FCC-constraint pulses are investigated under flat Nakagami-mfading channel and additive white Gaussian noise (AWGN). The numerical results show that two FCC-constraint pulses, PSP and MMNHP, have almost same sensitivity to the timing jitter even though they have different transceiver complexity. Additionally, the additional required power due to the timing jitter exponentially increases, but that due to the amplitude fading is not exceeded over 4dB.

The nonideal behaviour of astable multivibrators based on Negative Impedance Converter (NIC) type configuration is approached taking into consideration several nonidealities among which the slew-rate of the voltage operational amplifier (OA). Linear conversion of inductances, capacitances and resistances into time period is useful to measure impedances or physical quantities by means of impedance-type transducers. Following a series of investigations on this topic, a thorough study of four configurations for linear inductance-time and capacitance-time conversions based on the astable multivibrator viewed as a NIC-type nonlinear oscillator. Four circuits were studied, two of them having grounded reactive elements. The results can be used for linear capacitance-to-time (C|T) and inductance-to-time (L|T) conversions.

Ultra-wideband radio technology (UWB), is a wireless access technology that allows exchanging of data over a radio channel between over short distances at very high speed and low power consumption. UWB signals are short pulses the entire energy of which is distributed over a given wide region of the spectrum. With a sufficiently high total power transmitted over the air and with low power consumption and a pulsed nature of data transmission, a high data transmission rate can be obtained. This work has done interference analysis of ultra-wide bandwidth technologies (UWB) operating in the frequency band 7240-8240 MHz to the Earth monitoring and meteorological satellite systems that operate in this band. Taking into account the rapid development of users’ UWB devices in different frequency bands, the study tries to estimate the long-term impact of aggregate interference from UWB devices located around the satellite Earth stations. The study considers two satellite systems as an example of victim receivers. The UWB density assumptions made in the studies are based on the forecasts of CEPT and UWB Alliance.
