Published: November 2023

The study of the erosive manifestation in El Ogla and El Hadada watersheds showed a strong and accelerated erosive dynamic. The aggression of the rains, the unstable nature of the Lower Eocene clays and the pressure of humans on the marginal lands seem to be at the origin of the instability of the slopes. Thus, the preservation of lands requires a colossal effort from the part of the State as well as the peasants. Unfortunately, the majority of developments have been implemented on an ad hoc basis and are far from being implemented comprehensively. In El Ogla and El Hadada watersheds, bench terracing is the most spectacular form of State intervention. It is considered by technicians as the unique solution for all forms of erosion. However, the appearance of forms of failure in various sectors cannot neglect the good functioning of some of them in the stability of the slopes and the reduction of the water slide. The objective of this applied research is to evaluate the behaviour of these benches as an interactive system with the other components of the natural environment based on photointerpretation, field monitoring and the results of the diagnosis of the balance sheet displacement of sediments obtained from the application of the isotopic method of Cesium 137. This assessment of bench terracing is largely based on the Bugeat formula, which seems to be the most appropriate method for determining the suitable dimensions of both height and terrace spacing.

Published: November 2023

Lack of understanding of responsibility and commitment means that marriage is no longer in a holy and sacred position. Learning about the Islamic religion, especially in the chapter on marriage, is not sufficient provision to provide an understanding of how to build commitment. In the marriage material, graduation in the course is only 30% of the total number of students, this is because the learning model used still uses the conventional model. In an effort to minimize the loss of commitment to marriage, a learning strategy is needed by developing a learning model with project-based learning that aims to increase students' understanding of the material on marriage in Islam. The research aims to ensure that religious learning in public universities can increase understanding of marriage and reduce the number of divorces in marriage. This research uses a qualitative approach using the research and development method, namely developing a learning model to make it more interesting so that the material presented can be properly understood by students. The findings of the research results show that the development of the model carried out can increase the graduation rate to 100%. The model developed can answer the needs of learning Islamic religion in public universities.

Published: November 2023

Histamine intolerance, also referred to as enteral histaminosis or sensitivity to dietary histamine, is a disorder associated with an impaired ability to metabolize ingested histamine that was described at the beginning of the 21st century. Although interest in histamine intolerance has considerably grown in recent years, more scientific evidence is still required to help define, diagnose and clinically manage this condition. This article will provide an updated review on histamine intolerance, mainly focusing on its etiology and the existing diagnostic, differential diagnoses and treatment strategies.
Pollen-food allergy syndrome (PFAS)
Authors: Moldovan Sandra‑Iulia , Haidar Laura , Panaitescu Carmen
Published: November 2023

Pollen-food allergy syndrome (PFAS) is an immediate allergic reaction mediated by immunoglobulin E. This reaction occurs due to cross-reactivity between pollen and food in patients with previous pollen sensitization. PFAS causes symptoms such as itching, hives or oedema, mainly occurring in the lips, orally and pharyngeal, therefore being often referred to as oral allergy syndrome. However, systemic reactions such as anaphylaxis have been described more frequently recently. This diversity in the degree of symptoms is related to the types of trigger foods and the characteristics of the allergens (Jeon et al., 2020).
Synchronous electrochromism and electrofluorochromism in a zirconium pyrenetetrabenzoate metal-organic framework

Published: November 2023

Redox-active materials which exhibit both electrochromism and electrofluorochromism have great potential as multifunctional elements in optoelectronics. Here we present in situ spectroelectrochemistry on NU-1000, a zirconium pyrenetetrabenzoate metal-organic framework. A thin film of NU-1000 exhibits reversible color changes between light yellow and dark blue when subjected to an alternating electrochemical potential. In situ fluorescence excitation-emission spectral mapping elucidates a dominant blue emission of highly fluorescent electrochromic NU-1000 that is being quenched via an oxidation reaction. Density-functional theory calculations reveal the the forbidden optical transition between the singly-occupied molecular orbital (SOMO) and the lowest unoccupied molecular orbital (LUMO) in the oxidized linker as the cause of the quenching. Double potential step chronoamperometry meaures response times as fast as a dozen seconds and excellent switching stability over 500 cycles without noticeable attenuation of the color contrast. These findings provide valuable insight into the electrochromism and electrofluorochromism in metal-organic frameworks, offering exciting opportunities for developing advanced multifunctional porous materials with potential applications in optoelectronics and sensing.

Published: November 2023

Stacking between aromatic π-systems is fundamental to the design of supramolecular assemblies. Recently, π–π stacked antiaromatic π-systems have received considerable attention as some antiaromatic compounds can form closely stacked structures with substantial in-termolecular orbital interactions, resulting in the emergence of stacked-ring aromaticity. Here, we report three covalently linked norcor-role dimers that self-assemble to form supramolecular architectures. A 2,2’-linked norcorrole dimer with 3,5-di-tert-butylphenyl groups forms a face-to-face stacked dimer both in solid and solution states via homochiral self-sorting. Its association constant in solution is (3.6 ± 1.7) × 105 M–1 at 20 °C. In the solid state, 3,3’-linked norcorrole dimers with 3,5-di-tert-butylphenyl and phenyl groups afford macro-cyclic and helical supramolecular assemblies via heterochiral and homochiral self-sorting, respectively. Notably, the subtle modification in the substituent resulted in a complete change in the structure of the aggregates and the chiral self-sorting mode. The present findings demonstrate that structural manipulation in antiaromatic monomer units leads to the formation of various supramolecular assemblies on the basis of the attractive interactions between antiaromatic π-systems.

Published: November 2023

Digital twin laboratories, accessible via the use of low-cost and portable virtual reality (VR) headsets, have emerged as an immensely powerful tool for chemical education and research collaboration. Having an immersive environment identical to that of a laboratory can provide scientists with a unique platform in which to plan future experiments, conduct laboratory tours, and train on specialist equipment. However, what digital twin laboratories currently lack is on-hand support of co-workers to assist with tasks such as locating chemicals, aiding with machine set-up, and issuing reminders regarding local laboratory health and safety rules Here we show how this key gap can be overcome with the use of knowledge-loaded Chat-GPT avatars in VR. We trained three different chat avatars to perform specialist functions crucial to working in a laboratory and obtained accurate and useful responses in up to 95% of cases, using a range of evaluation metrics including Human Evaluation, Set-Based F1 Scoring, and BERTScore. Our findings demonstrate the vast potential of this technology in harnessing the capabilities of AI assistants for scientists and enhancing immersive digital twin environments within VR settings.
Cellulose-Callose Hydrogels: a Computational Exploration of their Nanostructure and Mechanical Properties

Published: November 2023

Polysaccharides play a crucial role in virtually all living systems. They also represent the biocompatible and fully sustainable component of a variety of nanoparticles, which are of increasing interest in biomedicine, food processing, structural reinforcement of polymeric materials and cosmetics. The computational modelling of complex polysaccharide phases will assist in understanding the properties and behaviour of all these systems. In this paper, structural, bonding and mechanical properties of $10$ wt\% cellulose-callose hydrogels ($\beta$-glucans co-existing in plant cell walls) were investigated by atomistic simulations. Systems of this kind have recently been introduced in experiments revealing unexpected interactions between the polysaccharides. Starting from initial configurations inspired by X-ray diffraction data, atomistic models made of $\sim 1.6 \times 10^6$ atoms provide a qualitatively consistent view of these hydrogels, displaying stability, homogeneity, connectivity and elastic properties beyond those of a liquid suspension. The simulation shows that the relatively homogeneous distribution of saccharide nanofibres and chains in water is not due to the solubility of cellulose and callose, but to the formation of a number of cross-links among the various sample components. The broad distribution of strength and elasticity among the links implies a degree of anharmonicity and irreversible deformation already evident at low external load. Besides the qualitative agreement with experimental observations, the simulation results display also quantitative disagreements in the estimation of elastic coefficients such as the Young's modulus that require further investigation. Complementary simulations of dense cellulose-callose mixtures (no hydrogels) highlight the role of callose in smoothing the contact surface of different nanofibres forming larger bundles. Cellulose-callose structures in these systems displayed an enhanced water uptake and delayed dye release when compared to cellulose alone, highlighting potential new applications as drug delivery scaffolds. The simulation trajectories provide a tuning and testing ground for the development of coarse-grained models that are required for the large scale investigation of mechanical properties of cellulose and callose mixtures in a watery environment.

Published: November 2023

A impressão 3D, ou fabricação aditiva, é uma tecnologia que permite a materialização de objetos tridimensionais, proporcionando soluções inovadoras (Correia, 2019). Com características estruturalmente sustentáveis e uma abordagem prática, essa tecnologia tem sido expandida para as mais diversas áreas de produção, iniciando-se sempre a partir de um processo de design. O estudo analisa a relação entre os campos da medicina e do design de moda a partir da perspectiva da impressão 3D com o objetivo de compreender o potencial do designer na contribuição para o bem-estar dos pacientes. Com o objetivo de promover o debate e a sistematização de possibilidades e inovações futuras, utiliza-se uma metodologia de análise qualitativa discursivo-imagética. Esta pesquisa teórico-metodológica está subdivida em duas etapas sequenciais: a) a delimitação do contexto histórico-cultural no qual emerge a inserção da tecnologia 3D ligada às melhorias e aos avanços da área da saúde por meio de um levantamento bibliográfico interdisciplinar; b) as possibilidades de construção de uma perspectiva inovadora por meio de casos reais que exemplificam, em diferentes níveis, a união entre a medicina e o design, assim como a análise de criações do design que podem levar a múltiplas possibilidades a serem investigadas futuramente. O artigo ilustra e analisa o papel do designer de moda mediante a criação de acessórios simultaneamente médicos e estéticos, e também investiga possíveis mudanças provocadas pela ampliação do acesso à tecnologia de fabricação aditiva, refletindo sobre as transformações que a profissão pode experienciar.
Ferramenta da moda artesanal como proposta metodológica para pesquisa em Psicologia Social
Authors: De Barros Soares Helena , Tittoni Jaqueline
Published: November 2023

O presente artigo descreve uma proposta metodológica utilizada em pesquisa que resultou em tese de doutorado em Psicologia Social – a ferramenta oferece possibilidades de aproximações colaborativas entre os campos da Moda e da Psicologia. A perspectiva decolonial da produção de conhecimento, que descortina a localização do ponto de vista de quem pesquisa, dá suporte para a construção dessa metodologia. Nomeada com base na artesania, a metodologia ponto atrás considera que diversas maneiras derelação com a roupa produz diferentes modas, no plural, como a Psicologia Social já vêm sendo entendida desde a referência de Rosane Neves da Silva (2004). A partir das problematizações de Heloisa Helena Santos (2019) para o conceito de moda, da reflexão sobre os modos de subjetivação colonizadores feita por Frantz Fanon (1983) e considerando a potência da autonomeação de pessoas e grupos subalterternizados baseada na proposta de Patricia Hill Collins (2019), o artigo propõe intersecções desses campos desde o repertório semântico até as ferramentas materiais.
UM OLHAR SOBRE A INTERDISCIPLINARIDADE NAS LICENCIATURAS EM CIÊNCIAS BIOLÓGICAS E QUÍMICA NA UNIVERSIDADE FEDERAL DE GOIÁS
Authors: Alonso Luri Braga , Vilela Marcos Vinícius Ferreira
Published: November 2023

O movimento interdisciplinar tem seus primórdios na Europa, na década de 1960. A década de 1990 é marcada pela massiva introdução do termo no cenário educacional brasileiro. Nos documentos orientadores da formação de professores de Ciências da Natureza, o uso reiterado do vocábulo interdisciplinaridade sem um tratamento conceitual adequado remete ao entendimento de que este se dá por mero modismo. Ante o exposto, o presente trabalho tem como objetivo compreender quais os sentidos atribuídos à interdisciplinaridade e se são apresentadas vias para sua implementação nos textos dos Projetos Pedagógicos de Cursos das Licenciaturas em Ciências Biológicas e em Química ofertados pela Universidade Federal de Goiás. Foi realizada uma pesquisa documental pautada nos princípios analíticos da Análise de Conteúdo. As categorias conceituais e analíticas utilizadas neste trabalho foram: 1. Concepção Hegemônica; 2. Concepção Crítica Instrumental; 3. Concepção Crítica. Apesar do modo multifacetado como o objeto interdisciplinaridade é depreendido nos documentos, a concepção que sobressai da análise é a crítica instrumental. Por conseguinte, a interdisciplinaridade é apresentada, de modo geral, como uma necessidade imposta pelos documentos orientadores oficiais, com o intuito de promover a contextualização dos conteúdos a partir de questões sociais complexas. Todavia, apesar do uso reiterado deste vocábulo nos documentos analisados, o tratamento teórico dado ao termo é deficitário e, além disso, não são apresentadas vias de implementação da interdisciplinaridade na formação de professores de Ciências/Biologia e Química.

“FIX ALL OF YOUR MENTAL PROBLEMS”: MESSAGE APPEALS AND THE USE OF
PERSONALISED MESSAGING IN THE ADVERTISING OF DIGITAL MENTAL
HEALTH AND WELL-BEING SERVICES
Authors:   , Vallely Patrick
Published: November 2023

It is common practice for advertisements relating to digital mental health and well-being services to include very bold and vague (abstract) claims when portraying the app’s benefits, as opposed to more informative or specific messaging (concrete). This often translates to advertising messages such as “Relieve all of your stress”, “Live better”, or “Fix all of your mental problems”. Personalised features within advertisements are also occasionally used for some services in order to further attract the consumer’s attention.

To date, no research has examined the effectiveness of concrete versus abstract message appeals and personalisation in advertisements for digital mental health and well-being services. This research categorises these digital mental health and well-being services as “self-appealing services” in relation to Belk’s (1988) theory of the self and the extended self.

Building upon previously published literature on message appeals, construal level theory, and personalisation, this study examines the direct effect message appeals (concrete versus abstract) and personalisation have on consumers’ perceived intrusiveness and behavioural intentions to use the service. It also examines the moderating role of concrete message appeals and the mediating role of perceived intrusiveness on these direct effects. A 2 (message appeals: concrete versus abstract) x 2 (personalised versus non-personalised) between-subjects experimental design (n=158) was employed to test these relationships.

Study findings demonstrated that the inclusion of a personalised message when advertising a digital mental health and well-being service lowers behavioural intentions to use the service and increases consumer perception of intrusiveness. Contrary to expectations, no significant difference was found in behavioural intentions when comparing the use of a concrete versus abstract message appeals in the advertising of a digital mental health and well-being service.

Additionally, concrete message appeals did not moderate the effects of personalisation on behavioural intentions and perceived intrusiveness. Finally, perceived intrusiveness negatively mediated the relationship between personalisation and behavioural intentions.

These findings offer several theoretical contributions to the body of knowledge on message appeals and personalised advertising in relation to self-appealing services. Study findings also have implications for managerial practice and social policy.

Authors: Moussa Nahla M. , Abdelmawla Moustafa M. , Mousa Jehad
Published: November 2023

In the current era, human diversity is constantly changing due to the exponential spread of information and communication technologies, which promotes human interaction. Cultural overlap between different societies, as well as increasing rates of migration across borders strengthen multiculturalism. The education system is often influenced by the cultural reformation in society, which shapes the way education is structured, teaching styles, curriculum development and education objectives. Given that Islamic culture is the dominant one in the Middle East, it is assumed that its ideals and principles will uphold multiculturalism and inclusion, as with any other great religions. This study aims to explore the role of Islamic culture in promoting multicultural education in the Middle East, to examine the application of the concepts of multicultural education, and to reflect on the idea of multiculturalism. A sample of 37 college instructors and 312 higher education students participated in the study by answering the questionnaire, which was conducted using a mixed-method approach. The results of the study showed that Islamic values and beliefs have a remarkable influence on the adoption of multiculturalism in education without compromising Islamic beliefs and values. Furthermore, multiculturalism ideas are incorporated into instruction and student communications. According to the research report, employing a multicultural education platform effectively will require curricular adaptation.

School principal can be both instructional and transformational leadership which is regarded as integrated leadership. Prior research has explored the connection between teacher job satisfaction, teacher collaboration, and teacher professional development. The current study aims to investigate the integrated principal leadership style, and its effect on teacher job satisfaction. We examined how integrated leadership indirectly influences teacher job satisfaction through the mediation of teacher collaboration and professional development. Voluntary sampling was conducted to collect research data. Electronic survey sent to 600 Indonesia which was 504 filled the survey completely. The partial least square structural equation modelling (PLS-SEM) was employed to analyze the data. The results showed that integrated leadership directly affected teacher job satisfaction in a positive way. Teacher collaboration and professional development had positively affected teacher satisfaction in their job. It was figured out that teacher collaboration and professional development have partial mediation effect on the relationship between integrated leadership and teacher job satisfaction. Based on results, integrated leadership has affected teacher job satisfaction directly. The effect was also mediated by teacher collaboration and teacher job satisfaction. Institutions should invest in leadership programs to equip principals with a blend of instructional and transformational skills that encourage teachers to develop their professional skills and to collaborate with others.

Published: November 2023

Two novel [ONO]-type tridentate Schiff base compounds namely (E)-2-(((2-hydroxyphenyl)imino)methyl)-4,5-dimethoxyphenol, C15H15NO4 (1), and (E)-2-(((5-chloro-2-hydroxyphenyl)imino)methyl)-4,5-dimethoxyphenol, C15H14ClNO4 (2) were synthesized. These compounds were characterized using various spectroscopic techniques, including single crystal X-ray diffraction (XRD), infrared (IR), proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR), and UV-Vis spectroscopy. The X-ray crystallographic analysis revealed that both compounds 1 and 2 contain two independent molecules within the asymmetric unit. Compound 1 crystallizes in the orthorhombic system with the Pna21 space group, while compound 2 crystallizes in the monoclinic system with the P21/c space group. An important feature observed in the crystal structure of compound 1 is the presence of O–H···N and O–H···O hydrogen bonds. In compound 2, the hydrogen bonding interactions involve C–H···O, O–H···O and O–H···N. Additionally, both compounds exhibit C–H···π interactions. To further understand the bonding interactions in compounds 1 and 2, Hirshfeld surface analyses and 2D fingerprint graphs were performed. The results indicate that the Hirshfeld surfaces are predominantly influenced by H⋯H, O⋯H, and C⋯H contacts.

This article reports the results of a study of Cr(VI) ions mutagenicity in the erythrocytes of Bufo viridis tadpoles under the influence of a low-frequency pulsed magnetic field (LF PMF). The tadpoles were randomly divided into 14 groups (n = 7). One group of intact tadpoles served as control. Other groups were experimental. The first six groups were placed for 24 h in water containing Cr(VI) at different concentrations (0.025, 0.05, 0.125, 0.25, 0.375, and 0.50 mg/L). The eighth group was subjected to an 8-h exposure to LF PMF (41 mT, 16 Hz). The remaining six groups of tadpoles were kept for 24 h in water with Cr(VI) ions at the specified concentrations and were also irradiated with LF PMF (41 mT, 16 Hz) during the first 8 h of this period. A day after the exposure, blood smears were taken, and the frequencies of micronuclei and nuclear anomalies in erythrocytes were analyzed. The results reveal that low concentrations of Cr(VI) (0.025 and 0.05 mg/L), unlike the higher ones (0.125 mg/L and above), did not significantly affect the frequencies of the analyzed anomalies. The combined action of Cr(VI) and LF PMF significantly increased the frequencies of the recorded anomalies in all the six variants of the experiment. The synergistic effect of Cr(VI) and LF PTF was shown.

Interferometry is a technique that can be applied to SAR (Synthetic Aperture Radar) images that allow obtaining Digital Elevation Models, displacement measurements and assistance for monitoring large areas and/or engineering constructions. The objective of this paper is to present aspects related to the technique of Interferometry SAR (InSAR) applied to the monitoring of slopes. To do so, a systematic bibliographical review was used, through research platforms in scientific collections, in order to highlight the functioning and method of operation of InSAR. Besides that, the practical experience of the authors contributed to a critical analysis of the remote sensing technique addressed. The results show theoretical aspects related to the operation of SARs on board satellites, highlighting their characteristics, orbital systems, types of imaging geometry, as well as the principles of interferometric processing of SAR images. Practical applications demonstrate the potential of InSAR with an emphasis on slope monitoring, highlighting its ability to acquire topographic information on a millimeter scale, monitoring the long-term temporal evolution of displacements, the possibility of composing a monitoring system allowing directing the implementation of other instruments for evaluating the in situ conditions and some limitations regarding the time interval (satellite revisit time) for the acquisition of the displacement data.

. Jan Amos Komenský was one of the most influential educators of 17th century Europe. As the bearer of the pedagogy of the new century, he influenced changes in pedagogical thought and education with his ideas and writings, and as one of the founders of pedagogy as a science, he was a role model for young educators. Throughout his rich career he insisted on teaching in the mother tongue and that schooling should not only be an educational institution but also one that fosters the moral character and spirit of the individual. He believed that learning should be fun and that in the process students should gradually progress from simple and basic concepts to complex ones. This greatest reformer in the history of education introduced a subject-oriented school system and insisted on lifelong learning. The aim of this paper is to show the place and role of Jan Amos Komenský in Serbian pedagogy in the late 19th century and the first half of the 20th century and to present the methods that were applied in the work of Serbian schools during this period.

This article traces the process of forming in the second part of the 19th century of interest in Russian tile as one of the original phenomena of national culture, reflected in the creation of its museum collections. The Historical Museum, founded in 1883, was amongst the first museums in Russia that established the major collections of tiles. Based on the study of its collection, the interest of researchers headed by I.E. Zabelin developed considering tile not only as a fragment of the decor of the building or of the stove, but as a self-contained art product and a museum item requiring attribution. The author examines the tiled stove of the middle of the 18th century from the SHM collection which is currently on the Moat bell tower of the Cathedral of the Protection of Most Holy Theotokos. The monument was a part of the collection of tiles formed in the first half of the 20th century in the branch of the Historical Museum «Pokrovsky Cathedral», and it has not been previously studied. This collection was transferred to the SHM Department of Ceramics and Glass in 2012, which did not only reveal new attributes of the tiled stove, but also restored the history of the monument. This article first describes the stove in detail, identifies the ratio of the original tiles to the 1920s copies, gives the analogues, and makes a statistical analysis of the painting composition. Although the stove was not included in the inventory of the collection of the famous Russian antique collector P.I. Shchukin in 1905 when the transfer to the Historical Museum took place, nor it was transported to the SHM funds after Shchukin’s death in 1917, detailed examination of unpublished archival documents allowed to attribute the monument with confidence to the Shchukin’s collection.
BOUNDARIES OF THE GENRE: ILLUSTRATIONS IN A POPULAR SCIENCE BOOK FOR CHILDREN (BY THE EXAMPLE OF THE TRAVEL BOOK BY A. LITVINA AND A. DESNITSKAYA “TRANSSIB. THE TRAIN IS LEAVING!”

Scientific illustration as an independent genre represents the specifics of the concept of “scientific” that has developed over three centuries of the development of the scientific method of European classical natural science. The basic characteristics of the scientific method and its private tools (including illustrations) are impartial, non-judgmental, non-subjective, emotionless modeling of the objects being studied and depicted. Illustrated popular science publications for children, as a tool of non-formal education with a supposed dual addressing, find themselves on the boundary line between scientific and educational illustrations. The complexity of the format is that it must be scientific, children educational, entertaining and popular at the same time. In handdrawn illustrations for such books, two very different ways of presenting the material can be distinguished. The article discusses the status of illustrations in terms of the possibility of classifying them as scientific in a children’s guidebook, made in a sketchy manner.

The NOV-01 well is a directional well that has technical problems (fish), namely the stuck pipe problem and the problem of high land use operational costs. Based on the results of the evaluation of the economic and risk technical aspects, a plug abandonment (PA) was carried out for the NOV-01 well. The purpose of this research is to compare the 3 stages and 5 stages in PA work and their influence on work program planning and budgeting. The research methodology is qualitative and quantitative. The NOV-01 well plug abandonment activity is carried out by preparing a work program plan such as determining the depth interval of the well to be plugged, the volume of cement slurry additives, as well as the rig method which all refer to the existing standards and regulations, namely SNI 13-6910-2002 and NORSOK D-010. The results of a comparative study on PA planning at 3 stages required 279 sacks of cement and 450 sacks of cement at 5 stages with a density of 15.8 ppg. PA on well NOV-01 uses the rig method with a capacity of 450 HP. For 3 stages it takes 9 days and 5 stages for 11 days. Comparison of estimated costs for PA of NOV-01 well, namely 3 stages of IDR 6,062,977,890.31- and 5 stages of IDR 8,374,824,218.62-. Well NOV-01, PA which is suitable is 5 stages because there is an overpressured zone so that the cement plug is isolated.

The background of this research is to support the plan to carry out 3D seismic acquisition in the Salawati Kepala Burung Working Area located in Sorong Regency. The 3D seismic design study was applied to better understand the physical properties of the Mesozoic clastic reservoir in the Salawati basin and its surroundings, especially in the offshore area. The study aims to evaluate the parameters of a reliable 3D seismic acquisition design to meet efficiency in financing in realizing the 3D seismic data acquisition program. Determine the recording parameters to image the Kais Formation and Waripi Formation targets by building a geophysical analysis model using existing 2D data and well-log information. Based on this model, using the Kais and Waripi formation properties to calculate and analyze vertical and horizontal resolution, bin size, aperture migration, and maximum offset. Synthetic acquisition 2D modeling is applied in this study to perform vertical and horizontal resolution analysis and obtain optimum and reliable bin size parameters and aperture migration. With this knowledge, we calculate the theoretical parameters of the survey. After determining the most critical theoretical parameters of the study, the next step is to determine the distance between the source and receiver. Then define the recording template. It is done by considering the bin size for the 3D model, offset boundaries, and suitable folds for inner targets. In the second, an analysis of the other two most important attributes is carried out, namely the offset and azimuth distribution. It is realized that every 3D survey design compromises technical factors affecting 3D survey costs starting from the technical requirements of field activities. The results of this study are recommendations and suggestions for two main alternative models of recording parameters and templates in the form of ideal source-receiver layout models, namely orthogonal and diagonal, and the minimum prerequisites that are expected to be able to map and determine the characteristics of the shallow and deep play type models in the South Walio offshore areas.
