Authors: Hromushin V. , Hadarcev Aleksandr , Grachev R.
Published: September 2022

The relevance of the hygienic assessment of the pollution of the territory of residence is determined by the influence of air pollution on human health. The considered method of generalized assessment allows not only to quantify the pollution of the territory, but also to calculate the share values of the analyzed pollutants, which is important for the formation of priorities for decisions to reduce the pollution of the territory. The proposed method is considered on the example of a specific calculation of the proportion of samples of priority pollutants in excess of the maximum allowable values in the atmospheric air.

Published: September 2022

Introduction. Endoscopic procedures for inguinal hernia repair have become widespread. There are many methods of such treatment: transinguinal preperitoneal mesh-plasty (TIPP), TAPP, TEP, MINI (combination of TEP and TAPP). However, the most common among them are TAPP and TEP. Despite the fact that these procedures are now common in many hospitals, the choice of tactics and repair procedures for different types of inguinal hernias is still uncertain. First, it concerns the quality of life of patients.

Aim. The aim of this study was to compare TAPP, TEP and Lichtenstein based on quality of life analysis using the EuraHS-QoL scale.

Materials and methods. We performed surgical treatment of inguinal hernia in 211 patients. Lichtenstein's procedure was performed in 65 patients (Lichtenstein group), transabdominal preperitoneal (TAPP) inguinal hernia repair in 81 patients (TAPP group) and totally extraperitoneal (TEP) inguinal hernia repair in 65 patients (TEP group). We assessed quality of life using a special scale for hernias (EuraHS-QoL). The missing values were treated according to the instructions of the validation study.

Results and discussion. As we expected, inguinal hernia repair improved EuraHS-QoL scores in all groups. In the Lichtenstein group, the total mean decreased from 51.2 to 11.8 (4.3 times) (r=-0.13), in the TAPP group – from 51.1 to 9.9 (5.2 times), in the TEP group – from 51.2 to 12.6 (4.1 times). Cosmetic discomfort was highest at the follow-up visit in patients in the Lichtenstein group (4.2). In the TAPP group, this indicator was probably (p<0.05) the smallest (3.0). Low-traumatic methods of operations in modern surgery are priorities today. The Lichtenstein procedure, despite its simplicity, is a traumatic operation compared to TAPP and TEP.

Conclusions. Different options for inguinal hernia repair, which are based on the tension-free principle of inguinal canal correction, can be useful. However, when we analyzed the quality of life according to the EuraHS-QoL scale, we decided that transabdominal preperitoneal (TAPP) inguinal hernia repair is the most optimal in terms of various indicators.
Patient decisions in a domiciliary setting
Authors: Finch John
Published: September 2022

Nurses working in the community frequently begin their professional relationship with a patient based on the reason for which their services were initially sought; but, as the relationship develops, community nurses can find that their strictly clinical expertise is not the only factor in the relationship which the patient seeks. This article looks at some aspects of the relationship between practitioner and patient which go beyond the strictly clinical and which attract further legal and ethical considerations. These further responsibilities may not have been examined in detail during training and can be learned only by experience.
Reporting Public Multicriteria Decision-Making Applications:
Authors: Mu Enrique
Published: September 2022

The following reflections refer to the development and reporting of public decision-making studies. These observations are provided with the hope of improving the quality and validity of multicriteria decision-making (MCDM) studies in the public sector. While my thoughts here are not intended to be a comprehensive study of how to report public MCDM studies, my intention is to highlight some key elements that are often not properly addressed by researchers. These observations are particularly relevant for AHP/ANP applications due to their widespread use in public decision-making.
Lightweight prohibited item detection method based on YOLOV4 for x-ray security inspection

Published: September 2022

In the area of public safety and crime prevention, some research based on deep learning has achieved success in the detection of prohibited items for x-ray security inspection. However, the number of parameters and computational consumption of most object detection methods based on deep learning are huge, which makes the hardware requirements of these methods extremely high and limits their applications. In this paper, a lightweight prohibited item detection method based on YOLOV4 is proposed for x-ray security inspection. First, the MobilenetV3 is used to replace the backbone network of YOLOV4, and the depthwise separable convolution is used to optimize the neck and head of YOLOV4 to reduce the number of parameters and computational consumption. Second, an adaptive spatial-and-channel attention block is designed to optimize the neck of YOLOV4 in order to improve the feature extraction capability of our method and maintain the detection accuracy. Third, the focal loss is utilized to avoid the class imbalance problem during the training process. Finally, the method is evaluated on our real x-ray pseudocolor image dataset with YOLOV4 and YOLOV4-tiny. For the overall performance, the mean average precision of our method is 4.98% higher than YOLOV4-tiny and 0.07% lower than YOLOV4. The number of parameters and computational consumption of our method are slightly higher than YOLOV4-tiny and much lower than YOLOV4.
Scanning measurement of surface error and thickness variation of the hemispherical resonator
Authors: Zhai Dede , Guo Jingyang , Chen Shanyong , Lu Wenwen
Published: September 2022

Hemispherical resonant gyroscopes (HRGs) are solid-state vibration gyroscopes with the highest precision and are widely used in the aerospace field. The core part of the gyroscope is the resonator, which is a thin-walled hemispherical shell. Surface error and thickness variation of a hemispherical shell causes frequency splitting, which degrades the performance of the HRG. In order to guide the mass leveling of hemispherical resonator, this paper presents a new method for scanning measurement of the surface error and thickness variation of hemispherical resonators. First, a multi-axis platform is designed for noncontact sensor scanning measurements along the meridian and latitudinal lines of the hemispherical resonator. Second, the error model of the measurement system is established. The surface error of the standard sphere is measured to calibrate and compensate for the assembly errors of the measuring device. In addition, the identification accuracy of assembly errors and the influence of assembly errors on thickness measurement are simulated by a computer. Finally, the surface error and thickness variation of the hemispherical resonators are measured. The method is experimentally demonstrated and validated with a wavefront interferometry test. The results show that the method can achieve high precision and high repeatability, which is instructive for assessment of the machining error and further evaluation of the hemispherical resonator.
Topography stitching in the spatial frequency domain for the representation of mid-spatial frequency errors

Published: September 2022

Sub-aperture fabrication techniques such as diamond turning, ion beam figuring, and bonnet polishing are indispensable tools in today’s optical fabrication chain. Each of these tools addresses different figure and roughness imperfections corresponding to a broad spatial frequency range. Their individual effects, however, cannot be regarded as completely independent from each other due to the concurrent formation of form and finish errors, particularly in the mid-spatial frequency (MSF) region. Deterministic Zernike polynomials and statistical power spectral density (PSD) functions are often used to represent form and finish errors, respectively. Typically, both types of surface errors are treated separately when their impact on optical performance is considered: (i) wave aberrations caused by figure errors and (ii) stray light resulting from surface roughness. To fill the gap between deterministic and statistical descriptions, a generalized surface description is of great importance for bringing versatility to the entire optical fabrication chain by enabling easy and quick exchange of surface topography data between three disciplines: optical design, manufacturing, and characterization. In this work, we present a surface description by stitching the amplitude and unwrapped phase spectra of several surface topography measurements at different magnifications. An alternative representation of surface errors at different regimes is proposed, allowing us to bridge the gap between figure and finish as well as to describe the well-known MSF errors.

In metazoa, cilia assembly is a cellular process that starts with centriole to basal body maturation, migration to the cell surface, and docking to the plasma membrane. Basal body docking involves the interaction of both the distal end of the basal body and the transition fibers/distal appendages, with the plasma membrane. Mutations in numerous genes involved in basal body docking and transition zone assembly are associated with the most severe ciliopathies, highlighting the importance of these events in cilium biogenesis. In this context, the ciliateParameciumhas been widely used as a model system to study basal body and cilia assembly. However, despite the evolutionary conservation of cilia assembly events across phyla, whether the same molecular players are functionally conserved, is not fully known. Here, we demonstrated that CEP90, FOPNL, and OFD1 are evolutionary conserved proteins crucial for ciliogenesis. Using ultrastructure expansion microscopy, we unveiled that these proteins localize at the distal end of both centrioles/basal bodies inParameciumand mammalian cells. Moreover, we found that these proteins are recruited early during centriole duplication on the external surface of the procentriole. Functional analysis performed both inParameciumand mammalian cells demonstrate the requirement of these proteins for distal appendage assembly and basal body docking. Finally, we show that mammalian centrioles require another component, Moonraker (MNR), to recruit OFD1, FOPNL, and CEP90, which will then recruit the distal appendage proteins CEP83, CEP89, and CEP164. Altogether, we propose that this OFD1, FOPNL, and CEP90 functional module is required to determine in mammalian cells the future position of distal appendage proteins.
Selection on modifiers of genetic architecture under migration load
Authors: Proulx Stephen R. , Teotónio Henrique
Published: September 2022

Gene flow between populations adapting to differing local environmental conditions might be costly because individuals can disperse to habitats where their survival is low or because they can reproduce with locally maladapted individuals. The amount by which the mean relative population fitness is kept below one creates an opportunity for modifiers of the genetic architecture to spread due to selection. Prior work that separately considered modifiers changing dispersal, recombination rates, or altering dominance or epistasis, has typically focused on the direction of selection rather than its absolute magnitude. We here develop methods to determine the strength of selection on modifiers of the genetic architecture, including modifiers of the dispersal rate, in populations that have previously evolved local adaptation. We consider scenarios with up to five loci contributing to local adaptation and derive a new model for the deterministic spread of modifiers. We find that selection for modifiers of epistasis and dominance is stronger than selection for decreased recombination, and that selection for partial reductions in recombination are extremely weak, regardless of the number of loci contributing to local adaptation. The spread of modifiers that reduce dispersal depends on the number of loci, epistasis and extent of local adaptation in the ancestral population. We identify a novel effect, that modifiers of dominance are more strongly selected when they are unlinked to the locus that they modify. These findings help explain population differentiation and reproductive isolation and provide a benchmark to compare selection on modifiers under finite population sizes and demographic stochasticity.
Human-Plant Coevolution: A modelling framework for theory-building on the origins of agriculture
Authors: Angourakis Andreas , Alcaina-Mateos Jonas , Madella Marco , Zurro Debora
Published: September 2022

The domestication of plants and the origin of agricultural societies has been the focus of much theoretical discussion on why, how, when, and where these happened. The ‘when’ and ‘where’ have been substantially addressed by different branches of archaeology, thanks to advances in methodology and the broadening of the geographical and chronological scope of evidence. However, the ‘why’ and ‘how’ have lagged behind, holding on to relatively old models with limited explanatory power. Armed with the evidence now available, we can return to theory by revisiting the mechanisms allegedly involved, disentangling their connection to the diversity of trajectories, and identifying the weight and role of the parameters involved. We present the Human-Plant Coevolution (HPC) model, which represents the dynamics of coevolution between a human and a plant population. The model consists of an ecological positive feedback system (mutualism), which can be reinforced by positive evolutionary feedback (coevolution). The model formulation is the result of wiring together relatively simple simulation models of population ecology and evolution, through a computational implementation in R. The HPC model captures a variety of potential scenarios, though which conditions are linked to the degree and timing of population change and the intensity of selective pressures. Our results confirm that the possible trajectories leading to neolithisation are diverse and involve multiple factors. However, simulations also show how some of those factors are entangled, what are their effects on human and plant populations under different conditions, and what might be the main causes fostering agriculture and domestication.
Prosocial spending encourages happiness: A replication of the only experiment reported in Dunn, Aknin, and Norton (2008)

Published: September 2022

Spending money on one’s self, whether to solve a problem, fulfill a need, or increase enjoyment, often heightens one’s sense of happiness. It is therefore both surprising and important that people can be even happier after spending money on someone else. We conducted a close replication of a key experiment from Dunn, Aknin, and Norton (2008) to verify and expand upon their findings. Participants were given money and randomly assigned to either spend it on themselves or on someone else. Although the original study (N = 46) found that the latter group was happier, when we used the same analysis in our replication (N = 133), we did not observe a significant difference. However, we report an additional analysis, focused on a more direct measure of happiness, that does show a significant effect in the direction of the original. Follow-up analyses shed new insights into people’s predictions about their own and others’ happiness and their actual happiness when spending money for themselves or others.
Neighborhood satisfaction and reproductive status
Authors: Neal Zachary P. , Neal Jennifer Watling
Published: September 2022

Both urban planners and urban scholars have been keenly interested in identifying the characteristics associated with neighborhood satisfaction. One robust but surprising pattern is that the presence or number of children in a household has no effect on neighborhood satisfaction. To clarify this pattern, we measured the neighborhood satisfaction of a representative sample of 1,000 Michigan adults, whom we divided into six distinct reproductive statuses: co-parents, single-parents, empty nesters, not-yet-parents, childless individuals, and childfree individuals. We found that a simple parent vs. non-parent dichotomy hides significant heterogeneity among these groups. Specifically, we found that single parents and childfree individuals experience significantly less neighborhood satisfaction than other groups. We conclude by reflecting on the methodological and practical implications of differences in neighborhood satisfaction when more nuanced reproductive statuses are considered.
Origin and diversification of free-living stick spiders of Sri Lanka including the description of four new species of Rhomphaea L. Koch, 1872 and two new species of Neospintharus Exline, 1950
Authors: Tharmarajan Mathura , Benjamin Suresh P.
Published: September 2022

Sri Lanka is a biologically diverse South Asian island, and together with the Western Ghats (Southern India) is one of the 36 world’s most biologically diverse areas. Here, we investigated the origin and diversification of Rhomphaea and Neospintharus of Sri Lanka using sequences of three genes: mitochondrial cytochrome c oxidase I (COI) and 16S rRNA (16S); and nuclear 28S rRNA (28S). Our phylogeny included 32 taxa (30 ingroup and 2 outgroup). We used Bayesian Inference and maximum likelihood methods to reconstruct the placement of species, divergence time estimations and their foraging behavior with an emphasis on species from Sri Lanka. Our phylogenetic hypothesis support the monophyly of Argyrodinae as well as the monophyly of Rhomphaea, where Rhomphaea is a sister group of Neospintharus. Further, our analysis also suggests that Sri Lanka was colonized by Argyrodinae several times. Additionally, the following new species are described: Rhomphaea shanthi sp. nov., Rhomphaea jacko sp. nov., Rhomphaea martini sp. nov., Rhomphaea marani sp. nov., Neospintharus kandelensis sp. nov. and Neospintharus ohiyiaensis sp. nov.

Published: September 2022

Little is known about the individual factors, such as knowledge and attitudes (i.e., football safety knowledge, football attitudes), related to adults’ willingness to allow adolescents to participate in tackle football. To address this gap, this study examined the extent to which football safety knowledge and attitudes toward head injury risk are associated with adults’ willingness to allow teenage boys to play high school tackle football. Data were obtained from an internet-based survey of a nationally representative sample of U.S. adults aged 18 to 93 years (n = 1,018). We conducted multilevel linear regression modelling to examine independent effects of the football safety knowledge- and attitude-based predictors. Our analyses revealed that knowledge of football safety measures, along with four of the five attitude-based variables were significantly associated with adults’ willingness to allow teenagers to participate in tackle football, over and above demographic factors. This study provides the first nationally representative examination of willingness to allow tackle football participation while extending our understanding of the gap between policy, public perception, and behavior present in U.S. high school football. These results point to promising directions for stakeholders aiming to increase tackle football participation as an increased understanding of the factors associated with participation may help inform effective policymaking, intervention design, and parental decision making.

An imagined space with an imagined time: Analysis of English language textbooks used in state schools in Pakistan
Authors: Khokhar Ashar Johnson , Muhammad Yaar
Published: September 2022

English textbooks in Pakistan are an important tool used by the state to construct pupils’ imagination of the time and space of the Indian sub-continent, Islam, Muslims and non-Muslims. This study used the qualitative content analysis method and analysed fifteen English textbooks produced by the state-managed institutions and provincial textbook boards. The analysis revealed Islam as the foundation of the imagination of time and space of Pakistan. This imagination of Pakistan found in textbooks negated the plurality of Pakistani society as the textbook authorities did not give any space to the minority groups (religious, ethnic and cultural) living in Pakistan. This study recommends that the textbook authorities include the often-ignored minority groups in the textbook discourses because the majority of pupils form their world-views and construct their imagination of Pakistan, its people and the world through these textbooks, which contribute to pupils’ construction of their national and cultural identity.
Lived experiences of first-time caregivers in early childhood music classes
Authors: Salvador Karen , Mayo Whitney
Published: September 2022

While scholars are interested in parent perspectives on early childhood (EC) music education, the perspectives of first-time attendees and non-maternal caregivers are relatively unexamined. Using phenomenology as both a method and a theoretical frame, we followed ten caregivers (three fathers and seven mothers) as they engaged in their first experience accompanying their children to play-based, child-led EC music classes. Through analysis of pre- and post-interviews, biweekly e-mail check-ins, memos and field notes from observations, we distilled four essences of first-time experience: being family, fitting in, engaging with others and having fun. In this article, we describe each essence and offer interpretation through our lens as mothers, scholars and EC teachers.

Published: September 2022

Variações naturais do nível do mar, mudanças climáticas e ações antrópicas fazem do ambiente costeiro um local dinâmico. O entendimento dos processos costeiros que ocorrem nas praias apresenta-se cada vez mais necessário para analisar as mudanças que ocorrem na morfodinâmica associadas às variações climáticas. O presente trabalho teve como objetivo analisar a variação da morfológia e da sedimentologia em duas praias de Santa Catarina durante as estações do ano, entre o período de agosto de 2017 a agosto de 2018. Também foram mapeadas as correntes de retorno durante a temporada de verão (2017/2018) e registrados os respectivos acidentes por arrastamento identificando os locais com maiores riscos aos banhistas. Quatro perfis transversais ao longo da praia de Cabeçudas e quatro na praia do Atalaia foram monitorados por levantamento topográficos com periocidade mensal utilizando-se o programa BMAP – Beach Morphodinamics Analysis Package para análise da largura e volume de cada perfil. As larguras das praias variam entre 32 a 115 m e o volume de 35,63m³/m a 179,62m³/m. A sedimentologia foi analisada, através do software SYSGRAN versão 3.0,  demonstrou que a praia de Cabeçudas apresentou areia fina e média com granulometria entre 0,22 a 0,39 mm. Já a praia do Atalaia apresentou areia fina com granulometria entre 0,14 a 0,20 mm. Com os parâmetros analisados constatou que a classificação morfodinâmica da praia de Cabeçudas foi reflectiva, enquanto a praia do Atalaia apresentou um estágio dissipativo. Foram observadas de 6 pontos de corrente de retorno na praia de Cabeçudas e 7 pontos de incidência na praia do Atalaia. Embora os números de pontos de corrente de retorno tenham sido similares, os acidentes na praia do Atalaia (35) foram um pouco mais que o dobro do que na praia de Cabeçudas (15). A praia do Atalaia se apresentou mais estável, com acréscimo de sedimento, enquanto Cabeçudas mais instável, variando entre perda e acréscimo de sedimentos. Provavelmente essa diferença seja decorrência dos diferentes estágios de preservação entre as duas praias.  A praia do Atalaia apresenta um maior perigo aos banhistas com mais locais de incidência de correntes e maior índice de acidentes por arrastamento.

Published: September 2022

Laut dan pesisir Kabupaten Cirebon banyak dimanfaatkan untuk pertambakan, penggunaan lahan mangrove, penangkapan ikan, dan budidaya perairan. Meningkatnya aktivitas domestik, rumah tangga, dan industri memberikan dampak negatif bagi perairan laut yakni pencemaran. Pencemaran yang terjadi salah satunya ialah pencemaran logam Pb terhadap Anadara granosa atau kerang dara. Anadara granosa merupakan hewan bentik dan filter feeder dimana akumulasi logam Pb lebih besar dibandingkan dengan biota laut lain, hal tersebut perlu diperhatikan mengingat kerang dara diminati oleh masyarakat untuk dikonsumsi. Tujuan penelitian ini ialah mendapatkan kadar logam Pb pada substrat, air laut, dan Anadara granosa yang diambil dari Kecamatan Gunung Jati, Kabupaten Cirebon sebagai wilayah penangkapan ikan. Metode yang digunakan ialah metode survey dan penentuan stasiun penelitian menggunakan metode purposive sampling. Pada setiap stasiun dilakukan pengambilan sampel substrat, air laut, dan Anadara granosa untuk diketahui kadar logam Pb. Penentuan kadar logam Pb pada sampel dilakukan di Laboratorium Sentral Universitas Padjajaran Jatinangor, Sumedang, Jawa Barat merujuk pada pedoman SNI 066992.3-2004 menggunakan instrumen Spektrofotometer Serapan Atom. Hasil penelitian menunjukkan rata-rata kadar logam Pb substrat sebesar 19,53 mg/l, air laut sebesar 0,16 mg/l, Anadara granosa sebesar 1,07 mg/kg. The sea and coast of the Cirebon Regency are widely used for aquaculture, mangrove land use, fishing, and aquaculture. Increasing domestic, household and industrial activities harm marine waters, namely pollution. One of the pollutions that occur is the contamination of Pb metal against Anadara granosa or virgin shells. The hyena shells are benthic animals and filter feeders where the accumulation of Pb metal is greater than that of another marine biota, it is necessary to pay attention to this, considering that the hymen is in demand by the public for consumption. The purpose of this study was to obtain Pb levels in the substrate, seawater, and virgin clams. The method used is a survey method and the determination of the research station using a purposive sampling method. At each station, substrate, seawater, and virgin shellfish were sampled to determine the Pb metal content. Determination of Pb metal content in the sample using an Atomic Absorption Spectrophotometer. The results showed that the average Pb content of the substrate was 19.53 mg/l, seawater was 0.16 mg/l, and virgin clams were 1.07 mg/kg.
Kajian Sedimen Tersuspensi di Muara Sungai Jelitik untuk Mendukung Pengembangan Kawasan Ekonomi Khusus Sungailiat, Kabupaten Bangka

Published: September 2022

Sungai Jelitik merupakan sungai utama dan urat nadi perekonomian Kecamatan Sungailiat, Kabupaten Bangka. Muara Sungai Jelitik termasuk dalam kawasan rencana pengembangan Kawasan Ekonomi Khusus (KEK) Pariwisata Sungailiat. Selain itu, Pelabuhan Perikanan Sungailiat juga terletak di alur Sungai Jelitik dan akan dikembangkan sebagai kawasan industri. Permasalahan utama yang dijumpai saat ini adalah sedimentasi di mulut muara S Jelitik yang diantaranya terkait konsentrasi sedimen tersuspensi. Oleh karena itu sebagai langkah awal dilakukan kajian tentang sedimen tersuspensi (TSS) ini. Metode kajian ini adalah pengambilan sampel air, analisis laboratorium dan analisis data. Kandungan TSS di perairan sekitar muara S Jelitik berkisar 65–250 mg/l dengan nilai rerata 128,28 mg/l, hal ini menunjukkan bahwa perairan di sekitar muara S Jelitik tidak memenuhi baku mutu baik untuk budidaya biota, untuk wisata maupun untuk pelabuhan berdasarkan PP 22 tahun 2021. Konsentrasi TSS di bagian tengah kedalaman sedikit lebih tinggi dibandingkan dengan konsentrasi TSS di bagian bawah kedalaman air laut. Kecepatan endap padatan tersuspensi di muara S Jelitik berkisar antara 0,0197–0,0858 mm/dt, dengan nilai rata-rata sekitar 0,0399 mm/dt. Sehingga sedimen tersebut baru terendapkan ke dasar perairan setelah 75.187 detik (20,88 jam) atau sekitar 0,87 hari apabila kondisi arusnya tenang.  The Jelitik River is the main river of Sungailiat District, Bangka Regency. The Jelitik River Estuary is included in the area of the Sungailiat Tourism Special Economic (KEK) development area. Besides, Sungailiat Fishing Port is located in the Jelitik River channel and will be developed as an industrial area. The main problem currently encountered is sedimentation at the mouth of the S Jelitik estuary. Sedimentation is strongly associated with turbidity and suspended sediment concentration. Therefore, as a first step, a study of this suspended sediment is carried out. The method of this study is water sampling, laboratory analysis, and data analysis. The TSS value in the waters around the S Jelitik estuary ranges from 65 - 250 mg/l with a mean value of 128.28 mg/l, this indicates that the waters around the S Jelitik estuary do not meet quality standards both for biota cultivation, for tourism and ports base on Government Regulation 22/2021. The TSS concentration at the center of the depth is slightly higher than the TSS concentration at the bottom of the seawater depth. The sedimentation rate of suspended solids in the S Jelitik estuary ranged from 0.0197 - 0.0858 mm/s, with an average value of about 0.0399 mm/s. So that the sediment is just deposited to the bottom of the water after 75,187 seconds (20.88 hours) or about 0.87 days if the current conditions are calm.

Karakteristik gelombang pasang surut akan mengalami transformasi ketika menjalar dari laut lepas ke perairan dangkal seperti pesisir pantai, estuari dan delta. Penelitian ini bertujuan untuk mengkaji transformasi elevasi pasang surut dari hilir ke hulu di Delta Berau meliputi komponen pasang surut utama semidiurnal dan diurnal (M2, S2, K1, dan O1), serta komponen pasang surut perairan dangkal M4 dan MS4. Metode analisis harmonik pasang surut menggunakan program T-TIDE di empat lokasi titik pengamatan (Tanjung Redeb, Batu Batu, Semanting dan Muara Tumbuk). Data elevasi pasang surut yang digunakan merupakan hasil observasi data lapangan pada waktu pengukuran dari 31 Mei – 27 September 2007. Hasil penelitian diperoleh bahwa amplitudo elevasi pasang surut mengalami peredaman dari arah hilir menuju hulu delta, komponen pasang surut semidiurnal M2 dan S2 berkurang 25%. Amplitudo komponen pasang surut diurnal O1 dan K1 berkurang 22%, sedangkan amplitudo komponen pasang surut perairan dangkal (M4 dan MS4) bertambah 370% dan 220% dari hilir ke hulu delta. Ketidaksimetrisan pasang surut diperlihatkan dengan perbedaan durasi waktu ketika menuju pasang (4-5 jam) dan menuju surut (7-8 jam) di Tanjung Redeb. Rasio amplitudo M4 dan M2 (Ar) diperoleh nilainya bertambah dari hilir ke hulu, dengan rasio maksimum bernilai 0,1 di Tanjung Redeb. The characteristics of tidal waves will transform when they propagate from the open sea to shallow water such as coast, estuary and delta. The present study aims to examine the tidal transformation from downstream to upstream in the Berau Delta, including the main tidal components of semidiurnal and diurnal (M2, S2, K1, and O1), as well as the tidal components of shallow waters M4 and MS4 are using the T-TIDE harmonic analysis method at 4 locations (Tanjung Redeb, Batu Batu, Semanting dan Muara Tumbuk). The tidal elevations were obtained from field observations in the period from May 31 to September 27, 2007. The results showed that the tidal elevation amplitude decreased from downstream to upstream of the delta, and the M2 and S2 semidiurnal tidal components decreased by 25%. The amplitude of diurnal tidal components O1 and K1 decreased by 22%, while the amplitude of shallow water tidal components (M4 and MS4) increased by 370% and 220% from downstream to upstream of the delta. Tidal asymmetry is indicated by the difference in the duration of high tides (4-5 hours) and low tides (7-8 hours) in Tanjung Redeb, and the difference in duration of high and low tides decreases (more symmetry) from upstream to downstream of the delta. The ratio of M2 and M4 amplitude shows that the value increases from downstream to upstream, with a maximum ratio of 0.1 in Tanjung Redeb.

Pemetaan pesisir meliputi wilayah daratan dan perairan, batas antara darat dan air (laut) disebut garis pantai. Permukaan laut secara periodik berubah atau yang umum disebut pasang surut air, sehingga batas darat dan air juga berubah. Pemetaan dengan data dasar citra satelit sekarang sudah umum dilakukan. Citra satelit merekam sesaat pada suatu waktu tertentu, jika pada wilayah pantai tentunya adalah batas darat dan laut adalah ketinggian air sesaat yang terekam oleh citra sehingga garis pantai akan berbeda antar perekaman. Kajian ini akan membahas bagaimana penentuan garis pantai dengan mengunakan metode gabungan terestris dan penginderaan jauh (data citra) dengan memperhatikan waktu perekaman dan tinggi air sesaat. Citra satelit yang digunakan adalah Landsat-8 dan pengukuran terestris menggunakan metode GNSS (Global Navigation Satelite System). Hasil yang diharapkan adalah metode hibrid dalam penentuan garis pantai sehingga dapat digunakan dalam produksi peta pada wilayah pesisir.
