Published: December 2024

Traditional weaving in West Nusa Tenggara was essential to the region’s cultural heritage. Many local micro, small, and medium enterprises continued to practice traditional weaving using natural materials. However, the rise of synthetic materials threatened this tradition, making distinguishing between natural and synthetic woven fabrics difficult. This study aimed to develop a blockchain-based self-certification system to enhance traceability, security, and efficiency using Non-Fungible Tokens. The research method leveraged the Elliptic Curve Digital Signature Algorithm for user authentication and smart contracts to mint Non-Fungible Tokens, ensuring the authenticity and origin of each product.Each product’s metadata was signed with a digital signature that anyone could authenticate, and the outcome and the product metadata became a certificate. This study resulted in a web prototype with an easy-to-use interface that allowed artisans to create certificates and sell their registered works. This solution aimed to ensure the authenticity of traditional woven products by offering secure and transparent blockchain technology.

The purpose of this research is to classify Study Programs based on eleven mixed data from InternalQuality Management System (QMS) indicators. This grouping can provide a clearer picture of howQMS affects the performance and quality of study programs. By understanding these clusters, universities can identify and design more effective strategies to improve the quality of education. The dataused comes from the National Accreditation Board for Higher Education (BAN-PT) and the websitedatabase, which consists of seven numerical variables: number of lecturers, percentage of doctors, percentage of professors and associate professors, student enumeration, percentage of graduates, programexperience, and availability of laboratories. Meanwhile, the categorical variable consists of four variables: National Accreditation Board of Higher Education (BAN-PT) research ranking, accreditation,international recognition, and level of community service. The clustering method used is the blockbased k-medoids (block-based KM), and multivariate analysis of variance (MANOVA). We applied theDeviation Ratio Index based on K-Medoids (DRIM) to determine the number of clusters. This researchresults that the optimal number of groups that must be formed is three. Based on MANOVA the resultsshowed that the group consisting of 12 study programs had better QMS outcomes than the other twogroups.

Published: December 2024

Special Region of Yogyakarta (Daerah Istimewa Yogyakarta, DIY) is well-known for its tourist, cultural, and educational attractions, but it also has a high accident rate. Sleman Regency is among the DIY regions with the greatest number of traffic accidents. According to Yogyakarta Police records, Sleman Regency had 1,825 traffic incidents in 2022, while 637 accidents occurred there in a short period of time in 2023, specifically from January to April. To stop the rising number of people injured in road accidents, this issue needs to be taken into account. The objective of this study was to examine the profile of traffic accidents that happened in Sleman Regency between January and April of 2023 and use the ordinal logistic regression method to find characteristics that influence the severity of traffic accidents. Sleman Regency traffic accident data was used in this study. The opponent's vehicle factor, with the category of four or more wheeled vehicles and non-motorized vehicles, is one of the elements that influences the severity of traffic accident victims in Sleman Regency, according to the study's findings.

Published: December 2024

Accurate modeling is expected to minimize risk and maximize profit in investment portfolios, one ofwhich is in stock price modeling. This research aims to model the causal relationship between stockprices using the Vector Autoregressive - Generalized Autoregressive Conditional Heteroskedasticity(VAR-GARCH) model. The VAR-GARCH model is used to overcome heteroscedasticity and modeldynamic volatility. The data used for the modeling consists of daily stock prices from July 2023 toMay 2024 for mining sub-sector companies listed on the Jakarta Islamic Index (JII), including ADMR,ADRO, and ANTM. The results showed that the VAR(1) model is stable, but this model indicates thepresence of heteroskedasticity or ARCH effects. Therefore, the VAR(1) model was combined with theGARCH model, and the results showed that the best model is VAR(1)-GARCH(1,1). The VAR(1)-GARCH(1,1) model is appropriate and meets the homoskedasticity assumptions for modeling the stockprices of the mining sub-sector in the Jakarta Islamic Index (JII). This indicates that the VAR-GARCHmodel could successfully handle the volatility of stock price data. In general, this research is in linewith previous research, i.e., the VAR-GARCH model showed a better model for capturing the volatilitypatterns in the data.

Published: December 2024

In 2022, the high school dropout rate is the highest compared to other levels of education in Indonesia.Seeing the urgency of the 12-year Compulsory Education program, completing education up to the highschool level is an important thing that needs to be considered. Thus, it is necessary to know the factorsthat influence the dropout rate in the hope that this problem can be reduced. This study aims to modelthe high school dropout rate using geographically weighted generalized poisson regression (GWGPR)based on the factors that influence it. GWGPR is used if the response variable is overdispersed anddepends on the location observed. The results of this study indicate that each province has a different regression model. The GWGPR model with the adaptive tricube kernel weighting function is thebest model because it has the smallest AIC value compared to other weighting functions. In CentralSulawesi Province, the GWGPR model with the adaptive tricube kernel weighting function formed isµˆ26 = exp (8, 1267 − 0, 1267X4 + 0, 0344X5 + 0, 0957X6 + 0, 1173X7). With the significant variables are the average length of schooling, the percentage of the population aged 7-17 years who receivePIP, the open unemployment rate, and the percentage of children who do not live with parents.

Published: December 2024

Тіньова економіка являє собою значну загрозу для національної фінансової системи України. Це економічна діяльність, яка прихована від суспільства та держави, не контролюється та не враховується державними органами. Основною метою даного дослідження є аналіз тіньової економіки як загрози для національної фінансової системи України. Метою дослідження є виявлення основних причин і наслідків тіньової економіки, оцінка її впливу на макроекономічні показники та розробка рекомендацій щодо зниження рівня тінізації економіки. У дослідженні використано методи аналізу офіційних статистичних даних Міністерства фінансів України та Національного Банку України. Застосовано економетричні моделі для оцінки впливу тіньової економіки на макроекономічні показники. Визначено методи оцінки рівня тіньової економіки, такі як: витрати домашніх господарств, метод споживання електроенергії, метод ОСТ, збитковість підприємств та монетарний, які використовуються для аналізу різних аспектів тіньової діяльності. Дослідження виявило, що тіньова економіка безпосередньо впливає на втрату державних доходів, бюджетний дефіцит та державний борг. Недоотримання податкових надходжень, спричинене тіньовою економікою, призводить до зростання бюджетного дефіциту та державного боргу. Тіньова економіка також створює проблеми для банківської системи та кредитування, ускладнюючи моніторинг грошових потоків та кредитних ризиків. Крім того, значна частка економічної активності, що не відображається в офіційних статистичних даних, ускладнює проведення ефективної монетарної політики, що впливає на рівень інфляції. Для ефективної боротьби з тіньовою економікою необхідно застосовувати макроекономічні фінансові інструменти, такі як: реформування податкової системи, використання сучасних технологій, підвищення прозорості роботи державних органів, здійснення ефективної монетарної політики та стимулювання інвестицій. Ці заходи сприятимуть зниженню рівня тіньової економіки, зміцненню національної фінансової системи та забезпеченню стабільного економічного розвитку країни. Лише спільними зусиллями держави, бізнесу та громадянського суспільства можна досягти значних успіхів у боротьбі з причинами тінізації економіки.

Published: December 2024

Масштаби гуманітарної кризи в Україні, спричиненої війною, є найбільшими з часів завершення Другої світової війни. В умовах значного потоку міжнародної гуманітарної допомоги до України виникає необхідність організації належного обліку цієї допомоги у отримувачів. Існуючі методики обліку гуманітарної допомоги, засновані на міжнародних стандартах та попередньому досвіді інших країн, потребують адаптації до умов України. Додаткові зусилля та вимоги потрібні як з боку донорів, так і з боку держави Україна та отримувачів, щоб забезпечити прозорість та відповідність використання гуманітарних ресурсів. Метою дослідження є аналіз особливостей документування та обліку надходження і розподілу матеріальної та грошової гуманітарної допомоги в Україні. У дослідженні застосовано методи причинно-наслідкового аналізу, синтезу, логічного узагальнення, а також табличний метод для систематизації даних. Ці методи дозволили визначити ключові аспекти документування надходження гуманітарної допомоги та її обліку, включаючи форми первинних документів, що використовуються на всіх етапах – від заявки до передачі кінцевим набувачам. Встановлено, що для належного документування і обліку гуманітарної допомоги в Україні необхідно запровадити чіткі форми первинних документів та кореспонденції бухгалтерських рахунків. Запропоновано форми документів для оформлення операцій руху гуманітарної допомоги, включаючи аналітичні рахунки для відображення надходжень та використання допомоги. Також досліджено специфіку обліку гуманітарної допомоги у вигляді іноземної валюти, що надходить в Україну. Наголошено на важливості отримання письмової пропозиції від донора і письмової згоди від отримувача для визнання допомоги гуманітарною. Дослідження показало, що належна організація обліку гуманітарної допомоги в Україні є критично важливою для забезпечення прозорості та цільового використання ресурсів. Запропоновані заходи щодо впровадження чітких форм документів і аналітичних рахунків сприятимуть покращенню обліку гуманітарної допомоги та відповідності міжнародним стандартам. Подальші дослідження можуть бути зосереджені на адаптації запропонованих методик обліку в умовах динамічних змін законодавства і міжнародних вимог.

Anayasacılık hak ve özgürlüklerin garanti edici fonksiyonunu ifa ettiği ilkeler ve kurumlar manzumesidir. Anayasa buradaki ilke ve kurguların somutlaştığı en üst düzeydeki hukuki belgelerdir. Bu doğrultuda anayasalaşma, ilerici haklar doktrinin harekete geçtiği bir alanı ifade etmektedir. Bu yönüyle anayasalaşma, anayasacılığın haklar paradigması ile ilgili ulus ötesi güçlü normatif iddialarda bulunmaktadır. Bu aynı zamanda ulusal üstü yapı ve kurumların işleyişine ilişkin önemli bir gerekçelendirme sunmaktadır. Dolayısıyla anayasalaşmanın yapılandırma eksenli kurucu bir hedef seçtiği ve bunu gerçekleştirmek için muhtemel işbirlikçi alanları aradığı giderek önem kazanan bir gerçekliktir. Gerçekten de ulusalın ötesinde anayasal normların doğuşu, geleneksel devlet anlayışını ve diğer uluslararası aktörün sahip olduğu statükoya dair kimlik değiştirme ve normatif olarak kendini sınırlamayla beliren yeni bir sürece işaret etmektedir. Böyle olunca, küresel toplulukların yönetişim standartları yararına gelişen anayasal normların, bunlara dair gerekli hukuki tutarlılığı sağladığı ve küresel hukuk devleti ve demokratik çoğulculuğu gerçekleştirebileceği görülmektedir. Çalışmamız tüm bu mülahazalar ekseninde anayasacılık anlayışının uluslararası hukuk bakımından da paradigma olarak ele alınmasını gaye edinmektedir.

Authors: Syahida Nidya Putri , Suryaningsih Suryaningsih
Published: December 2024

The problem that often occurs in planning is the Government's consistency in formulating plans, with accurate data or processes carried out not by applicable regulations, so sustainable development is only normative without any concern for achieving predetermined targets. However, the urgency of sustainable development cannot be overstated. It is an agenda echoed globally and has become the world's attention to resolve the gaps that have occurred so far. The pillars of sustainable development are social, economic, and environmental sustainability. These three pillars are derived into 17 indicators known as SDGS, which help make it easier to evaluate the achievement. This research method uses qualitative methods with data collection carried out both primary and secondary through interviews, observations, and document reviews. This study aimed to determine the integration of the sustainable development pillars in preparing the RPJPD document in West Lombok Regency. The urgency of this research is to find out the readiness and condition of the region to support the country in achieving sustainable development goals. The result of this research is that West Lombok Regency makes sustainable development the basis of long-term development planning (RPJPD).
Managing a Small Library: How to Color with Broken Crayons
Authors: Veldheer Kris
Published: December 2024

This is a book about small theological libraries, for small library directors. The subtitle, How to Color with Broken Crayons, is from a chat among a few members of Atla’s Small Libraries Interest Group. While discussing library size and resources, the directors longed for what they described as “the big box of 64 crayons to color with” that so many college and university library directors have access to. Instead, small library directors make do with a much smaller box of 8 crayons, which as one member quipped, is usually 8 broken crayons. Small libraries require the “wear many hats” approach often overlooked in books and articles on library management. This book focuses specifically on theological libraries or those libraries serving faith-based institutions with a mixture of theory and practical suggestions.
Carbon Capture Storage dalam Pengelolaan Barang Milik Negara
Authors: Budi Andri Setia , Falson Jerri
Published: December 2024

Climate change has gained prominence following the 2015 Paris Agreement, which aims to limit global temperature rise to below 2 degrees Celsius, with efforts to keep it under 1.5 degrees Celsius. This agreement stresses the importance of collective action to reduce greenhouse gas emissions and build resilience against climate impacts. In June 2023, the global average surface temperature reached a record high, with subsequent months also setting heat records. Mitigating global warming's adverse effects, such as rising temperatures and extreme weather changes, requires significant reductions in greenhouse gas emissions. Efforts in the energy sector have led to a decrease in CO2 emissions from 40.6 million tons in 2018 to 127.67 million tons in 2023. These efforts include enhancing energy efficiency, transitioning to renewable energy, and implementing carbon capture and storage (CCS) technologies In Indonesia, CCS regulations are outlined in Minister of Energy and Mineral Resources Regulation No. 2 of 2023. CCS involves the capture, transport, injection, and permanent storage of carbon emissions. The management of state-owned assets related to CCS falls under the Ministry of Finance Regulation No. 140/PMK.06/2020, which addresses the transfer, utilization, and valuation of upstream oil and gas assets. This paper discusses the role of state asset management in the implementation of CCS in Indonesia, examining current regulations, challenges, and future prospects.
Property Valuation: Using Machine Learning for Rent Value Prediction
Authors: Afrisca Cindy Clara , Rofiq Hanif Noer , Atmoko Darmawan Dwi
Published: December 2024

The rising demand for rental spaces, such as hotel lodging rooms, has led property owners in high-potential areas to begin renting out their properties to meet this need. The Directorate General of State Assets (DJKN) under the Ministry of Finance, which manages state-owned assets, oversees approximately 1,100 room units with potential for rental. In alignment on increasing non-tax state revenue from state-owned assets (BMN), offering lodging room rentals as a form of BMN utilization presents a promising opportunity for expansion. To facilitate efficient rental services for these BMN rooms, a quick and accurate valuation process is essential. However, establishing fair rental prices for both property owners and tenants poses a significant challenge. This study, therefore, aims to develop automated valuation model (AVM). Since rental price predictions depend on various bebas variabels, the study employs several machine learning algorithms, including Ridge, Linear Regression, Random Forest (RF), Lasso, SVR, Elastic Net, and Extreme Gradient Boosting. The research focuses on rental markets in Jakarta, Bogor, and Bandung, using a dataset of fewer than 500 rental room samples sourced from marketplaces. These data points are adjusted for state-owned asset variabels, followed by feature engineering. The performance of the various algorithms is then compared. The results indicate that the best-performing model and the most important features vary by city, but overall, the Random Forest model delivers strong performance, with room size, road width, and room quality emerging as the most influential factors.

Hasil penelitian menunjukkan bahwa kelemahan utama dalam pengelolaan piutang, terutama di sektor kesehatan, berkontribusi terhadap defisit keuangan. Selain itu, kelemahan dalam pencatatan persediaan dan pelaksanaan audit internal ditemukan di berbagai sektor, yang mengarah pada inefisiensi operasional dan menurunnya akuntabilitas publik. Fleksibilitas pengelolaan keuangan yang dimiliki BLU, meskipun memberikan otonomi dalam pengelolaan dana, dapat memperburuk masalah jika tidak diimbangi dengan sistem pengendalian internal yang kuat. Dengan demikian, peningkatan pengendalian internal, audit yang lebih ketat, serta pelatihan manajemen diperlukan untuk memperbaiki kinerja keuangan dan akuntabilitas BLU. Pemerintah disarankan memperkuat regulasi pengendalian internal serta meningkatkan kapasitas manajerial BLU melalui pelatihan keuangan dan risiko. Hasil penelitian ini berkontribusi pada literatur mengenai pengelolaan BLU dan memberikan rekomendasi kebijakan untuk meningkatkan efisiensi dan akuntabilitas BLU di Indonesia.

Published: December 2024

Open Radio Access Networks (O-RAN) are expected to revolutionizecommunication systems. O-RAN enables virtualized Radio Access Networkswhere distributed components are attached through open interfaces andintelligent controllers optimize the performance. A new conceptual design has been created for network configuration, deployment, and functions. This design uses interchangeable components from various vendors and can be optimized for performance through a centralized inference layer and data-driven control. However, due to the large number of users and limited capacity of the fronthaul in dense wireless systems, it becomes challenging to achieve optimal resource allocation in such massive systems. In this work, we balance the spectral efficiency and the required power, which will reduce the signalling overheads and processing in high-density radio access networks. More specifically, a linear channel estimation (based on the MMSE technique) is employed to design the Conjugate Beamforming vectors. The suggested iterative approach,namely LSF-IV, leverages the large-scale fading detection (LSF) and theintermediate value method (IV) to attain the balancing between users' uplink spectral performance. Concerning the algorithm validity and for a specific parameter setting scenario, the proposed approach can significantly enhance the spectral performance for the users in the worst channel conditions compared with the typical fractional PA. Adjusting a specific parameter can improve spectral performance by 45% with a 95% likelihood. This study found that using a more extended training sequence for channel estimation can result in a 27% improvement in spectral performance, based on a 95% likely percentage.

Digital beamforming (DBF) is a crucial technology for large antenna arrays, offering precise control over beam steering. This research introduces a novel method to enhance millimeter wave transmission by incorporating DBF with long-term memory (LSTM) based deep learning Our system utilizes digital signal processing and LSTM networks to optimize beamforming parameters instead of relying on traditional analog beamforming. The objective is to achieve high spectral efficiency. The methodology is executed in the programming language MATLAB and the obtained simulation outcomes validate a substantial enhancement in the metrics that evaluate performance, thereby demonstrating the potential of combining digital beamforming (DBF) with Long Short-Term Memory (LSTM) for forthcoming communication systems. Furthermore, the inclusion of LSTM in the process of digital beamforming presents a comprehensive comprehension of the proposed approach, which imparts valuable insights for advanced communication technologies. To substantiate the efficacy of the technique, several illustrative examples are employed to steer the beam pattern in the desired direction.

Authors: Hussein Alwan Iqbal
Published: December 2024

Since time immemorial, solar radiation has been used to hot water in domestic applications. In this study, simulation was used to determine the effectiveness of the water tank and its effect on the time and quantity of hot water supply. The simulation process done by using ANSYS fluent, for a water storage tank, where the water pipe was used as part of the physical process within the simulation program, and thus four types of thermal storage were used, the first without tubes and the second using a variable number of tubes (4, 6, 8) in thermal storage. In addition, three flow rate values were used, (4, 6, 8) L/m and solar radiation rates (437-630) W/m2 for the 31 days of January and the days (7,12,13,17,18) of the February. The results showed that the tank temperature increased as the flow inlet rate decreased. At 4 L/m, the temperature in storage rose to 42 °C at 12 Am, while at 6 L/m, the temperature rose to below 39 °C. Introducing water pipes inside the storge tank enhances heat accumulation and heat dissipation ability. Temperature peaks were recorded at 45°C using 8 water tubes and a flow rate of 4 L/m.

Published: December 2024

Proper thermal control is one of the most important aspects that should be considered when utilizing electrical transformers. This research work offers a numerical analysis of the effect of changing the shape of transformer fins on the heat exchange process. Based on the results of CFD simulations, several types of fin shapes such as rectangular, triangular and wavy are discussed to describe the improvements of heat transfer. The study examines the shape of an electrical transformer, determining the optimal distance between fins, fin shapes, transformer shape, rib type, and rib number. The results are then applied to a special case, representing the best of all variables on the transformer. The study also considers the effect of increasing the surface area of the ribs on the fins, and the number of ribs used on the fins. The temperature gradient of a coil, oil, and transformer varies depending on the distance between fins, fin shape, rib type, and number of ribs. The coil temperature is 383 K when the fins are 7 cm apart, 381 K when the fins are 5 cm apart, and 381 K when the fins are 3cm apart. The temperature gradient also varies depending on the rib type, with triangular ribs increasing the surface area for heat energy transfer and reducing the temperature value. The oil temperature gradient varies depending on the fins, ribs type, and number of ribs. The heat transfer coefficient gradient of the transformer surface varies depending on the fins, ribs type, and number of ribs. The surface heat transfer coefficient reaches 1.5 W/m2. K when the fins are l shape, 1.6 W/m2. K when the fins are c shape, 1.7 W/m2. K when the fins are z shape, 1.4 W/m2. K when the ribs are rectangular, 1.6 W/m2. K when the ribs are triangular, and 1.4 W/m2. K when the ribs are 9 ribs.

Published: December 2024

The utilization of Autonomous vehicles has been rapidly increasing in both civilian and military applications. This is primarily due to their exceptional communication capabilities with ground clients, as well as their inherent properties such as adaptability, mobility, and flexibility. To effectively monitor and control the deployment of Autonomous vehicles, a 5G wireless network can be utilized alongside other devices as user equipment (UE). Through the utilization of a highly directive microstrip patch antenna (MPA) functioning within a dedicated frequency band, the Autonomous vehicle is able to establish effective long-range communication, overcoming signal degradation and minimizing interference from other channels within a confined area. The adoption of MPA is especially advised for Unmanned Aerial Vehicles (UAVs) due to its characteristics such as being lightweight, cost-efficient, small in size, and having a flat structure. This study details the development and simulation of a highly directive single-band 1x2 and 1x4 antenna array designed to operate at a 5.8 GHz frequency specifically tailored for Autonomous vehicle use. To enhance directivity and ensure structural robustness, the Roger RT5880 material has been utilized as a substrate, known for its lower dielectric constant.. The results demonstrate a high gain of 9.16 dBi and 11.4 dBi for the 1x2 and 1x4 antenna arrays respectively, while maintaining a compact size. The simulated 1x4 antenna array was fabricated using the Roger RT5880 material, and this array was tested in the microwave communication's laboratory at College of Engineering, Al-Nahrain University. The antenna presents good results by means of return losses (-26.672 dB) which equivalent to VSWR of 1.098.

Published: December 2024

The long-term impact of waterborne solids may lead to the destruction of significant amounts of concrete in hydraulic structures, including spillways, dams, and culverts. Hydraulic structures' durability heavily depends on the concrete surface's resistance to mechanical erosion. Abrasion of the surface brought about by the continuous loss of material due to the impact of solid particles suspended in water is known as hydro-abrasion. This kind of gradual degradation of the concrete surfaces is noticeable in almost all hydraulic structures, although to varying degrees. Hydro-abrasive concrete wearing often leads to a decrease in the lifespan of the hydrotechnical facility. Consequently, the facility needs repairs, causing it to be non-functional during the repair time and increasing expenses. This paper aims to provide a comprehensive overview of concrete abrasion and its mechanisms, as well as briefly discuss the elements that significantly affect the rate of abrasive erosion. The research also found that to enhance the abrasion resistance, concrete properties needed to be modified, along with an increase in compressive strength

Authors: Hmoud Amina , Hadi Obaid Mery  , Osamah Malik Mohammed
Published: December 2024

In this article natural air convection in an inclined annular cage in three dimensions is investigated numerically. This study will examine the impact of the radius ratio of an annulus on heat transfer employing two distinct methods to optimizing effective thermal conductivity: minimizing and maximizing. The annulus is built of graphite/epoxy laminated composite material. There are 12 fins attached to the inner cylinder of the two concentric cylinders that make up the annulus enclosure, which is filled with porous medium. Regarding the annulus's inclination angle “δ”, two scenarios—a horizontal annulus and a vertical annulus—are considered. Constant walls temperature boundary condition and steady state conditions apply to the system with 0.2, 0.3, 0.4 and 0.5 different radius ratio, inclination angle (0o and 90o), and modified Rayleigh number “Ra*”   ranged from 10 to 500, The Nusselt number decreased for all parameters as the radius ratio Rr decreased, indicating a wider cold outer cylinder gap. For large values of modified Rayleigh number, the average Nu number ”Nuavg.” decreases with an increase in δ, and increases with a rise in the modified Rayleigh number; for low values of Ra*, δ has no effect. For horizontal, and vertical states “δ=0 o, and 90o respectively, at higher and lower thermal conductivity, the divergence of the average Nusselt is 5.1% and 10%, respectively. In horizontal cylinder adding fins on the inner cylinder is more substantial for due to its impeding effect, and NuL increases with cylinder length. For the outer cold cylinder, a link between Ra* and δ and the average Nusselt number has been established.
