Authors: Wisnumurti Wisnumurti , Soehardjono Agoes , Simatupang Roland Martin
Published: March 2024

Cracks pose a significant issue in rigid pavement, leading to substantial damage. The manual mixing and casting of road pavement concrete underscore the importance of concrete quality as a critical parameter. This study investigates crack behavior by varying concrete quality. Loading is performed statically using line loads, shedding light on the impact of concrete quality on crack development. The concrete to be used has a quality fc' of 15 MPa, 25 MPa, and 35 MPa. The fine aggregate used in this study was Lumajang black sand, while the coarse aggregate used was machine crushed stone, and Portland Composite Cement (PCC) was used in all concrete mixes. The reinforcing steel used had a quality fy of 480 MPa, with a reinforcement ratio of ρ=0.010, which was converted to 5-D16 reinforcement. The subgrade density used to support the specimens had a CBR value of 10 %. Specimen dimensions were 2×0.6×0.2 m for length, width, and thickness. Pavement plates, 30 cm thick, were placed on leveled subgrade soil in a steel box set to achieve a 6 % CBR reading. Hydraulic jacks, monitored by a load cell, applied monotonic static loading with 2 kN intervals, reaching a maximum load of 200 kN. Steel tension and plate settlement were measured using a tension sensor and Linear Variable Differential Transformer (LVDT), respectively. A data logger recorded readings, and crack widths were captured by a digital microscope with 0.01 mm accuracy. Experimental results show that low concrete compressive strength values result in larger crack widths, and vice versa. Cracks also occur at earlier loading of concrete quality fc' 15 MPa. In addition, experiments show that the reinforcement stress value has a significant influence on crack width in specimens with low concrete quality
Defining compromise area in the processes of multimodal delivery organization within the agile approach
Authors: Berestenko Viktor , Onyshсhenko Svitlana
Published: March 2024

The level of competition in the transport market requires delivery organizers to implement better approaches based on modern management methodologies, in particular, agile, which makes it possible to provide a modern level of service to cargo owners.
The object of this research is the processes of organizing multimodal delivery. The subject of the study is the area of compromise in the processes of organizing multimodal delivery based on the agile approach.
The term «compromise area» is introduced, which reflects the numerical limits of product parameters in the general case. For the transportation domain under consideration, the «trade-off area» reflects the limits of the characteristics of multimodal delivery, which is the «product» for the multimodal operator.
A set of alternative options for multimodal delivery forms the basis for establishing the dependence of the cost of delivery on time and its reliability (possible time deviation). The area in the «time-reliability-cost» space, which is formed on the basis of this dependence, on the one hand, and the requirements of the cargo owner, taking into account their possible adjustment, on the other hand, is the area of compromise. This area is proposed for use in agile approaches to the organization of multimodal delivery. Balancing the interests of the cargo owner and the multimodal operator allows changing the limits of the compromise area within the framework of the proposed scheme of agile cycles in the process of planning and organizing delivery.
On the example of delivering a container with cargo from China to Kyiv, regression linear models were built. These models formalize the dependence of delivery cost on reliability and/or time. Using the example of varying the requirements of the cargo owner regarding the limitations of some delivery characteristics, the formation of the compromise area and its adjustment was carried out, which demonstrated the practical aspects of the formation of the compromise area for multimodal delivery.
The results are the basis for the implementation of the agile approach in the field of multimodal transportation. The further development of these results consists in the construction of mathematical models that could form the basis for finding solutions in the area of compromise

Authors: Sampelawang Petrus , Salam Nasaruddin , Sule Luther , Tarakka Rustan
Published: March 2024

Hydrokinetic turbines use different rotors for technological and economic reasons. Even though it performs poorly, vertical-axis hydrokinetic turbines use the Savonius rotor. The object of research is a Savonius rotor model with additional grooves. The study addresses the need to improve the efficiency and overall performance of Savonius rotor models in hydrokinetic turbines, which are widely used for harnessing energy from flowing water currents. The problem involves understanding how different groove configurations affect the aerodynamic behavior and energy extraction efficiency of the Savonius rotor in hydrokinetic turbine applications. The test results revealed that incorporating grooves led to notable improvements in efficiency (ɳ) and coefficient of drag (CD). Grooved blades exhibited a maximum efficiency of 30.97 % and a maximum drag coefficient of 2.71. Notably, blades with a groove width of 12.5 mm emerged as the optimal model, demonstrating an efficiency peak of 35.66 % and a drag coefficient 3.08. This indicates a substantial increase in efficiency by 4.69 % and a corresponding rise in the drag coefficient by 0.37 for grooved blades. The grooves on grooved blades increase friction, improving performance. Grooved rotor blades improve turbine performance significantly. Savonius rotor models in hydrokinetic turbines extract more energy by optimizing groove width and arrangement to maximize drag coefficient and efficiency. This research affects hydrokinetic turbine design and optimization for renewable energy generation. Engineers and designers can improve the performance and efficiency of the Savonius rotor model in hydrokinetic turbine applications by applying this study’s findings

Authors: Panchenko Serhii , Bychenko Artem , Nizhnyk Vadym
Published: March 2024

This paper reports results of an experimental study on hydrodynamic processes when water is dropped from a height, as well as their influence on the movement of liquid, in order to optimize the processes of aviation firefighting.
The main parameters of water dispersion were determined based on a series of experiments. It was established that the average diameter of drops when dropped from a height of 10 meters is 2.5 mm, with a maximum spraying distance of up to 15 meters. The size distribution of the droplets showed that 30 % of the droplets have a diameter of less than 2 mm, 50 % are between 2 and 5 mm, and 20 % are more than 5 mm.
During the experiments, it was measured that the time for pouring water from the container is 3 seconds, and the speed of movement of water fractions when dropped from a height of 10 meters is 9.8 m/s. With an increase in the discharge height by 5 meters, the speed of water movement increased by 20 %.
One of the key points of the study is the improvement of the Torricelli equation by introducing the coefficient K (0.85), which takes into account the viscosity and density of water, which improved the accuracy of calculations by 15 % compared to the standard equation.
Python was used to process and interpret the video data, along with libraries such as OpenCV for image processing, NumPy for high-performance mathematical computations, and Matplotlib for data visualization. The resulting data open up new prospects for devising aerial firefighting strategies, providing a 20 % increase in coverage area, and a 25 % reduction in firefighting time.
Torricelli's equation was improved; a new procedure was devised for the experimental determination of water dispersion parameters, which has an important practical application in the field of fire safety.
In the field of fire safety, the data obtained could be used to improve aviation firefighting strategies, which would allow for greater efficiency and safety
Development of method for frequency regulation of output current in high-voltage transformerless resonant chargers of capacitive energy storage devices
Authors: Vinnychenko Dmytro , Nazarova Natalia , Vinnychenko Iryna
Published: March 2024

The object of research is high-voltage systems of electric discharge installations for various technological purposes. The work reports solving the problem of enabling the rate of charging of a capacitive energy storage, set by the requirements of a certain high-voltage technology.
The quantitative characteristics of the deviation of the output current of the resonant inverter from the set stabilized value when changing the switching frequency of inverter switches in the range of output voltage change from 0 to 20 kV were determined. Using the Fourier transform of the rectangular input voltage, the frequency regulation possibility of the output current of the charger for capacitive energy storage devices was analyzed. Estimation dependences of the output current of resonant inverter on the load resistance and frequency deviation from resonant frequency were derived. These dependences could be used to implement frequency control over the switching inverter transistors, with the help of which the given effective value of the output current of the resonant inverter is obtained.
A method of frequency regulation of the output current in high-voltage transformerless resonant charging devices of capacitive energy storage devices has been developed. Special feature of this method is that it is based on the frequency dependence of reactive resistances of the inductance and capacitance of the resonant circuit connected in series. Owing to that, it makes it possible to adjust the switching frequency of the inverter’s power switches depending on the relative resistance of the load and the specified growth rate of the capacitive energy storage voltage.
The results reported here could be used in the design of benches for testing the electrical strength of high-voltage cables, as well as for the construction of high-voltage transformerless chargers in systems of electric discharge impulse processing of materials
Determining the thermally-stressed state of motor-driven bowls for transporting liquid slag
Authors: Povorotnii Viktor , Shcherbyna Iryna , Zdanevych Serhiі , Diachenko Nina , Kimstach Tetiana , Solonenko Lyudmila , Usenko Ruslan
Published: March 2024

Slag bowls were chosen as the object of research, as important components of blast furnace, steelmaking, and ferroalloy shops of metallurgical enterprises. The main problem of operation of any slag trucks is their limited durability and frequent destruction of slag bowls. The reason for these problems is changes in the shape of the bowls during operation, manifested in the formation of narrowing places in the area of the support ring – for rail-mounted bowls, destruction of supporting pins – for rail-mounted slag trucks, or cracks in the walls. Those defects appear as a result of cyclic thermal effects of liquid slag on the bowl. Based on the results of computer simulation, it was established that the main role in the destruction of the support pins of motor-driven slag bowls belongs to temperature changes. The temperature stresses arising in the bowl are localized in the area of the slag mirror (200–250 MPa for 25L steel, 280–350 MPa for 30HML steel). The results provide grounds for improving the presented slag bowl to reduce temperature stresses in its walls and structures of the supporting trunnions. The results reported here are explained by the fact that with uneven heating of elastic bodies, temperature stresses appear, which, under certain configurations of temperature loads, lead to the destruction of structures. The findings from these studies are recommended to be used at enterprises for the design and manufacture of slag bowls, as information on the localization of dangerous places of the structure. In addition, the data presented here could be useful for metallurgical enterprises for detailed technical diagnosis of bowls in their dangerous places

Authors: Can Sağlam Yeşim
Published: March 2024

Recently, the Industry 4.0 paradigm has commenced to swiftly grow in the supply chain management and logistics fields. Despite this development in the logistics and supply chain management domain, the investigations of smart logistics (also known as logistics 4.0) are still in maturity. Especially, some areas such as the drivers and inhibitors of smart logistics are still an adequately unexplored area. On the other hand, smart logistics provides highly practical solutions to overcome the increasing difficulties in logistics operations by enabling worldwide cooperation. For this reason, studies in the field of smart logistics are of critical importance. This study addresses this gap by investigating the driving factors to facilitate and barriers to the adoption of smart logistics in the context of the extant literature. A systematic literature review was conducted to provide a comprehensive result to capture the dynamics and benefits of smart logistics and identify barriers deserving of further academic interest. To summarize the novel investigations in this domain, forty (40) papers were chosen and properly analyzed. As a result of the analysis, it was revealed that there are 6 main barriers preventing the adoption and implementation of smart logistics. These are risk-related barriers, data and technology-related barriers, organizational-related barriers, human resource-related barriers, economic-related barriers, and regulation-related barriers. On the other hand, as a result of the literature review, critical factors (such as investing in smart logistics, developing technological infrastructure, generating organizational culture or mission toward smart logistics, and providing top management support) that will both overcome these obstacles and facilitate the adoption of smart logistics have been determined. The accumulation of knowledge and provided insights in this research will provide advantages for both practitioners and academics interested in this emerging novel technology segment.

Multi-Modal Attentive Prompt Learning for Few-shot Emotion Recognition in Conversations
Authors: Liang Xingwei , Tu Geng , Du Jiachen , Xu Ruifeng
Published: March 2024

Emotion recognition in conversations (ERC) has emerged as an important research area in Natural Language Processing and Affective Computing, focusing on accurately identifying emotions within the conversational utterance. Conventional approaches typically rely on labeled training samples for fine-tuning pre-trained language models (PLMs) to enhance classification performance. However, the limited availability of labeled data in real-world scenarios poses a significant challenge, potentially resulting in diminished model performance. In response to this challenge, we present the Multi-modal Attentive Prompt (MAP) learning framework, tailored specifically for few-shot emotion recognition in conversations. The MAP framework consists of four integral modules: multi-modal feature extraction for the sequential embedding of text, visual, and acoustic inputs; a multi-modal prompt generation module that creates six manually-designed multi-modal prompts; an attention mechanism for prompt aggregation; and an emotion inference module for emotion prediction. To evaluate our proposed model’s efficacy, we conducted extensive experiments on two widely recognized benchmark datasets, MELD and IEMOCAP. Our results demonstrate that the MAP framework outperforms state-of-the-art ERC models, yielding notable improvements of 3.5% and 0.4% in micro F1 scores. These findings highlight the MAP learning framework’s ability to effectively address the challenge of limited labeled data in emotion recognition, offering a promising strategy for improving ERC model performance.

INVESTIGATION OF THE IMPACT OF DRILLING WITH SIMULTANEOUS EXPANSION TO THE RATE OF CHANGE IN THE ZENITH ANGLE OF THE WELL
Authors: Zalyatdinov A.A. , Shaykhutdinova A.F.
Published: March 2024

The article discusses the use of various methods and techniques for isolating complication zones during drilling in the oil and gas industry. The main focus is on the process of isolating complication zones using profile closures, which allow maintaining the nominal di-ameter of the wellbore. To achieve this, it is necessary to increase the diameter of the complication interval using expanders. The article notes that the highest efficiency is achieved when drilling and expanding the wellbore simultaneously using expandable expanders. Such expanders have high wear resistance and can withstand significant loads. The article also ex-amines the challenges that arise when drillinginclined and directional wells with simultaneous wellbore expansion. One of the main problems is the spontaneous increase in zenith angle when incorporating the expander into the bottom assembly of the drill string. Wells drilled with simultaneous wellbore expansion were an-alyzed. After the analysis, it is evident that when the zenith angle exceeds 300 before the start of expansion, a more intense increase in zenith angle is observed during wellbore expansion. To solve this problem, the use of a managed drill string is proposed, which can adjust the zenith angle with a specified intensity or stabilize it throughout the interval.
STUDY OF THE WALL RIGIDITY OF A VERTICAL CYLINDRICAL STEEL TANK DURING ITS INSTALLATION BY THE SPIRAL-WOUND METHOD
Authors: Gnezdilov S.G. , Platonov D.E.
Published: March 2024

The paper presents the results of a study of the influence of the wall diameter of a vertical cylindrical steel tank designed for storing petroleum products on its stiffness characteristics and the applicability (for the manu-facture of this wall) of the spiral-winding metod, according to which the tank wall is made of rolled sheet metal, during the unwinding of which a wall is formed in the form of a spiral, ad-jacent turns of which are continuously connected by a welded seam, forming a sealed shell.To solve the problem, a finite element analysis of the tank wall was performed, within which the wind load was taken as the calculated one, due to which the greatest lateral deformations of the tank wall during its construction are possible, which can cause disruption of the technological process of its construction using spiral-winding method.The paper considers tank wall solutions of different diameters (in the range from 10 to 65 m), which have the smallest wall thicknesses adopted in accordance with the recommendations from the Russian standard.Modeling of the tank wall included the preparation of geometric and calculation models. The geometric model is presented in the form of an axisymmetric cylindrical shell, on the outside of which flat ribs are placed at a constant pitch along the shell axis, giving it additional stiffness. The calculation model includes a geometric model of the wall, to which a wind load is applied from the outside, the pressure from which on the tank wall is constant along its height; it is maximum under normal action and decreases to zero under tangential action. Using the calculation model, firstly, a dependence was obtained that reflects the effect of a change in the height of the tank wall on the maximum radial displacements in its base near the supports, and, secondly, the dependence of the maximum radial displacements of the tank wall in its base near the supports, depending on its diameter.The results of the analysis, in particular, showed that the stiffness of the wall obtained on the basis of the spiral-winding method practically does not change with an increase in its diameter (and a corresponding increase in thickness).
ABOUT THE MAIN RESULTS OF DEEP DRILLING IN THE TERRITORY OF THE PREDVERKHOYANSKAYA OIL AND GAS AREA

Published: March 2024

This article presents the results of drilling wells in the Predverkhoyanskaya oil and gas area, where deep exploratory drilling for oil and gas was started in 1954 at the Kitchan, Sangar and Ust-Vilyu structures pre-pared by the seismic survey in combination with structural core drilling.According to the results of deep drilling in the Predverkhoyanskaya oil and gas area, the section of the sedimentary cover was studied, and ideas about the material composition of the foundation upper part were obtained. The pro-spects of oil and gas potential are evaluated: the reservoir properties are possessed by rocks of the subsalt Nizhnevendsky, Vendian-Lower Cambrian terrigenous and carbonate complex-es, which are associated with industrial oil and gas potential in nearby fields.The following fluid-bearing complexes are distinguished in the sedimentary section of the Preverkhoyanskiy trough: Permian (P), Lower Triassic (T1), Triassic-Lower Jurassic (T2–3–J1), Middle Upper Jurassic (J2-3), Lower Cretaceous (K1).Deposits of the Lower Triassic aquifer complex are deposited on Permian formations. The capacity of the complex is variable, due to the structural features of the Lower Triassicsediments, and it has not been established with-in the Predverkhoyanskiy trough. Thermobaric data were not obtained during the test. Reser-voir pressures are close to hydrostatic. Reser-voir temperatures, as in the Permian complex, increase from west to south-east to the Predverkhoyanskiy trough from 50 °C to 95 °C.The deposits of the Middle-Upper Triassic – Lower Jurassic aquifer complex are more widely developed. During the sampling and test-ing of oil and gas exploration wells, water and gas inflows were obtained from the deposits of the complex, including industrial ones on Ust-Vilyuiskaya, Sobo-Khainskaya Square. The flow rates of water inflows reached 300 m3/day (Sangarskaya 2), gas inflows up to 1800000 m3/day (Ust-Vilyuiskaya area). In the Sobo-Khainskaya 1 well, an industrial gas in-flow was obtained from the interval of 1328–1349 m.The prospects for oil and gas exploration at the Preverkhoyanskaya oil and gas area are associated with its northern part (Setas struc-ture), on which the Setas parametric well No. 1 with a design depth of 4000 m is being laid, and its southern part, where it is advisable to drill 2 parametric wells with a planned depth of 3000 m.
Mining corporate boardrooms still a male club? Experiences and challenges faced by South African women
Authors: Moraka N.V.
Published: March 2024

Calls for transformation in the mining sector are legislated. Whilst the composition of boards in terms of gender diversity and equal representation has improved, little is known on how women directors experience boardrooms. This research investigated the experiences of South African women in male-dominated mining boards. It questions why women remain marginalised in boardrooms, even when they are qualified as the men in their respective fields. The experiences of South African women on male-dominated mining boards were investigated by means of a multiple case study using a qualitative research methodology. Interviews were conducted with 16 women and 12 men serving across six JSE-listed South African mining companies. The findings show that irrespective of their qualification and experience, women's, contributions are often ignored, and they are assigned to more social roles. Regardless of race, all women experienced gender stereotyping. Strategies are required to ensure that board cultures embrace female talent, where women can effectively contribute to decision-making and maximize their talent. It is argued that gender and identity should be studied in relation to post-colonial history in African countries. Women have multiple, varying identities, and their experiences require a unique investigation that would enable strategies to overcome barriers, through the implementation of an appropriate diversity management programme.
ПРОРОЧЕСТВА Н. Ф. ФЕДОРОВА О ВОЙНЕ В ТРАКТОВКЕ Н. А. БЕРДЯЕВА
Authors: Малахаткин Евгений Олегович
Published: March 2024

Цель статьи. В статье рассматривается анализ Н. А. Бердяева воззрений Н. Ф. Федорова о войне, которые он назвал пророческими, прежде всего, предсказания неизбежности именно мировой войны, в которой предвидел главную роль Германии.

Методология исследования базируется на традициях русской философской мысли.

Результаты. Делается вывод о том, что Н. А. Бердяев акцентирует внимание на том, что Н. Ф. Федоров хорошо понимает: Германия — носительница милитаристического индустриализма и «мировой пожар» возгорится по ее вине. Отмечается, что Н. А. Бердяев осмысляет воззрения Н. Ф. Федорова на войну, исходя из фундаментальных положений «философии общего дела» последнего. Это дает возможность увидеть такие принципиально важные вещи для федоровского понимания войны, как противопоставление «духа германизма» «духу расы славянской», использование армии для регуляции природных сил, прекращение войны как устранение розни через преодоление смерти и т. д. Рассматривается критическое отношение Н. Ф. Федорова к таким представителям немецкой философии, как Шопенгауэр, Кант, Ницше, которые явились идейным источником «духа германизма». На этом фоне выявляются типологические отличия немецкой «воли к власти» и русской «воли к правде». В заключении делается вывод, что анализ идей Н. Ф. Федорова, осуществленный Н. А. Бердяевым, имеет важно значение для понимания своеобразия философии войны в контексте фундаментальных идей русской философии.

Перспективы исследования заключаются в дальнейшем осмыслении феномена войны в русской философии.
АНАЛИЗ СВОБОДЫ ТВОРЧЕСТВА В КОНТЕКСТЕ СИНЕРГЕТИЧЕСКОЙ ТЕОРИИ
Authors: Шатохина Наталья Петровна
Published: March 2024

Цель исследования заключается в рассмотрении феномена свободы творчества в контексте синергетического метода как междисциплинарного поля исследования, позволяющего осмыслить данное явление во всей его полноте и противоречиях.

Методологический конструкт. Исследование феномена свободы творчества базируется на синергетическом методе. Синергетическая парадигма позволяет рассмотреть его как бифуркационный механизм, запускающий процесс самоорганизации сложных когерентных систем, задействованных в процессе созидания.

Результаты исследования. Синергетический метод дает возможность наиболее полно отразить процесс созидания, а именно — ситуацию выбора дальнейшего сценария создания творческого продукта. Состояние вдохновения, вынашивания произведения всегда характеризуется нестабильностью, изменчивостью, хаотичностью, тогда как итог творчества гармоничен и целостен. Рассмотрение процесса творчества и феномена свободы творчества как единого, сложносформированного целого, осуществляющего самоорганизацию произвольного структурогенеза, дает возможность обнаруживать скрытые механизмы, задействованные в творческом акте, выводит науку и культуру на новый уровень.

Перспективы исследования определяются тем, что синергетическая парадигма лабильна и применима к анализу самых разных природных и социальных процессов. Синергетика позволяет рассматривать любое явление как комплекс самоорганизующихся систем, способных переходить от хаотичности к упорядоченности.
ИНСТИТУЦИОНАЛЬНО-ПРАВОВОЕ РЕГУЛИРОВАНИЕ ИМУЩЕСТВЕННЫХ ОТНОШЕНИЙ МЕЖДУ БЫВШИМИ СУПРУГАМИ В СОВРЕМЕННОМ РОССИЙСКОМ ОБЩЕСТВЕ
Authors: Реброва Наталья Михайловна
Published: March 2024

Целью исследования является характеристика некоторых проблем правового регулирования имущественных отношений между супругами (бывшими супругами) и сложившихся в правоприменительной практике подходов к их разрешению, а также разработка предложений по совершенствованию законодательства в указанной сфере.

Методологическую базу составили методы науки семейного права, как общенаучные, так и специальные: анализа и синтеза, формально-логический. С их помощью выявлено содержание и дано толкование правовых норм, обобщены позиции Верховного Суда Российской Федерации по актуальным проблемам правоприменения, выраженные им при разрешении конкретных дел, сформулированы предложения по совершенствованию норм, регулирующих имущественные отношения между супругами (бывшими супругами).

Результаты исследования. Анализ правоприменительной практики свидетельствует о том, что существует насущная потребность в совершенствовании правового регулирования имущественных отношений между супругами (бывшими супругами). Однако следует признать, что такое совершенствование должно происходить эволюционно, а не путем революционного изменения правовых основ имущественных отношений между супругами (бывшими супругами). Прежде всего следует обратить внимание на проблемы, касающиеся раздела общего имущества супругов, и создать правовые условия для реализации супругами права изменить режим совместной собственности уже в момент приобретения имущества. Для этого следует законодательно закрепить право супругов включать в соответствующий договор положения о приобретении имущества в долевую или раздельную собственность и определить форму подобного договора. Поскольку режим совместной собственности как законный режим имущества супругов достаточно распространен, следует закрепить нормы, позволяющие сделать Единый государственный реестр недвижимости более достоверным: отражать в нем право общей совместной собственности супругов на объект во всех случаях, когда таковое возникает. Это позволит снять многие проблемы, связанные с заключением сделок с общим имуществом супругов (бывших супругов), защитить интересы как самих супругов (бывших супругов), так и добросовестных приобретателей.

Перспективы исследования предполагают дальнейший поиск путей совершенствования правового регулирования имущественных отношений между бывшими супругами с учетом меняющейся социально-экономической ситуации как с целью обеспечения интересов самих супругов (бывших супругов), так и с целью обеспечения стабильности гражданского оборота.

In 2019 Indonesia was ranked 4th (fourth) after Brazil, Vietnam, and Colombia as the world's largest coffee producer, 760,963 tons produced from 1.2 million hectares of land consisting of smallholder plantations (Perkebunan Rakyat / PR), large private plantations (Perkebunan Besar Swasta / PBS), and large state plantations (Perkebunan Besar Negara / PBN). The productivity of the plantation can be seen from comparing the area of the plantation with the production of coffee, the national productivity has only reached 0.77 tons of greenbean coffee/ha/year. This figure is considered still very small when compared to its potential which reaches 3tons of greenbean coffee/hectare/year. Temporal mapping method can be used to find out the level of productivity more easily based on location and time. Thus, the priority of handling coffee area becomes more focused and on target. The web-based GIS platform provides flexibility in terms of access and attractive appearance. The information presented is more communicative and easy to understand for interested users. This study uses ArcGIS Online with an operation dashboard to visualize the results of this study. The results showed that in the last two years arabica productivity in 2019 and 2018 was the highest in West Phak - Phak district with a figure of 1,575 kg/ha in 2019 and 1,580 kg/ha and the lowest was in Tabanan Regency at 29 kg/ha in 2019 and located in Wonosobo Regency at 26 kg/ha in 2018. For robusta in 2019 the highest was in Ogan Komering Ulu Timur district with a figure reaching 5,186 kg/ha and in 2018 the highest was in Kota Pagar Alam district with a figure reaching 2,890 kg/ha. ha and the lowest was in Muna Regency at 57 kg/ha in 2019 and in Nias Regency at 12 kg/ha in 2018.Keywords: ArcGis, Coffee, Coffee Producer, Operation Dashboard, Yield,

The issue of the North Natuna Sea between Indonesia and China has become a crucial issue that has yet to find a bright spot to resolve disputes in the region. The claim of the nine dash line or nine dashes unilaterally by China has caused losses for Indonesia to the full sovereignty and integrity of the country which is included in the Exclusive Economic Zone in the North Natuna Sea. Although each country has ratified UNCLOS (United Nations Convention of the Law of the Sea) or ratified it as the International Law of the Sea, it means that every decision is based on the force of law that has been mutually agreed upon. China considers claims based on historical aspects (historical) at the time of their ancestors in the past. However, according to Law Number 5 of 1983 referring to UNCLOS, it is stated that the Indonesian Exclusive Economic Zone (ZEEI) is a path outside and bordering the Indonesian Territorial Sea as determined based on the applicable law concerning Indonesian Waters which includes the seabed, the land beneath it. , and the water above it with an outer limit of 200 nautical miles measured from the baseline so that the North Natuna Sea is or is included in the full rights of Indonesia. In this case, Indonesia has binding legal force to file a claim against or defense against China which claims arbitrarily and clearly violates the International Law of the Sea (UNCLOS). Through the writing of this paper, it aims to analyze and deliver input from the scientific aspects of geodesy and geomatics through an opinion on the resolution of the North Natuna Sea problem that Indonesia has strong evidence and is in accordance with the law so as to provide opportunities for resolving disputes in the region.Keywords: Exclusive Economic Zone,Dispute, North Natuna Sea, Nine Dash Line, UNCLOS
Economic–Sanitation–Environmental (Dis)Connections in Brazil: A Trans-Scale Perspective From Minas Gerais State and BH Microregion
Authors: Valencio Norma , Valencio Arthur , Carvalho Gabriel G. , Baptista Murilo S.
Published: March 2024

Brazil’s economic, environmental, and infrastructural landscape is characterised by local and regional inequalities, particularly evident in Minas Gerais state and the municipalities surrounding its capital, Belo Horizonte (BH) microregion. This research examines three primary domains: (a) economic metrics such as GDP per capita, wages, and formal employment; (b) the availability of clean water and sewage systems; and (c) the frequency of emergency decrees. It aims to ascertain whether these factors can delineate economic, health, and socio-environmental divides within the BH microregion and between its urban and rural areas. Economically, a pronounced gap exists between GDP growth and wage stability, underscoring disparities between the BH microregion and the broader state. While the BH microregion boasts higher salaries and GDP, it also grapples with a heightened cost of living. Disparities in water and sewage infrastructure are stark between urban and non-urban locales, with the latter often lacking access. Emergency decrees are correlated with municipal GDP, with lower-GDP areas experiencing more crises, albeit to a lesser extent in the BH microregion. Cluster analysis reveals a nexus between frequent emergencies, lower GDP, and improved access to water and sewage services. Addressing these challenges requires comprehensive public policies to foster local well-being and alleviate economic, infrastructural, and environmental disparities within both the state and the BH microregion.
Inhabiting Flyover Geographies: Flows, Interstices, and Walking Bodies in Karachi
Authors: Haque Aseela
Published: March 2024

Flyovers have featured in critical urban planning scholarship in the Global South as fetishized symbols of modernity, often fragmenting urban environments, fracturing space, exacerbating inequalities, and embodying “worlding”’ aspirations of city planners. Acknowledging the role of such infrastructure as technologies of (dis)connection in increasingly enclaved cities, I seek to situate the flyover, its material form, and attendant gaps, characterized by raised ribbons of “smooth” flows, leftover spaces, and proliferation of informal practices, as important sites of encounters. As such, I take “borderland urbanism” as an impetus to think flyover geographies anew by locating the flyover as a particular place in the city that is transient, contested, and constantly re-made. Through ethnographic vignettes and interviews, I sketch out everyday urban experiences over and under a flyover in Karachi, Pakistan. I illustrate how the flyover as a spatial and temporal leap is perceived and experienced by a range of differently mobile urban dwellers, paying particular attention to how walking bodies inhabit an infrastructural landscape that heavily privileges cars and motorcycles. Furthermore, I trace how life in the interstices under the flyover is assembled through social collaboration, resisting eviction, and a politics of visibility.

Office of Institutional Integrity Annual Report 2008
Authors:   Inter American Development Bank
Published: March 2024

In 2008, the Office of Institutional Integrity (OII) entered its fifth year of operation. OII is an independent unit of the Inter-American Development Bank Group (IDB or Bank Group). During 2008 OII¿s responsibilities for supporting internal integrity efforts have diminished. In 2007, the Bank created an internal Ethics Office and hired an Ethics Officer. OII¿s externally-focused efforts have increased. In the past year, the Office responded to an ever-growing number of inquiries and completed 150 investigations. This was the second year in which the Bank Group made this list public. Disclosing sanctions is one of the mechanisms that reinforces the Bank Group¿s message that it will deal severely with those responsible for the misuse of funds and failure to comply with its anti-corruption policies. Additionally, OII improved the efficiency and effectiveness of its use of human, technological and knowledge-based resources in its investigative processes. In 2008, there was also significant progress in the area of prevention. OII continued to support the Institutional Capacity of State Division. Particular attention was directed to identifying and implementing initiatives under the Anti-corruption Activities Trust Fund (AAF).
