Married couples: The significance of psychological wellbeing and subjective loneliness for feelings of love
Authors:   St. Petersburg State University, Troshikhina Evgenia
Published: May 2024

Married couples are attracting attention of psychologists. Generally, feelings of love are studied as a predictor, and psychological wellbeing as an effect of relationship satisfaction. Since feelings of love change in time, the purpose of this research is to study gender and age differences and identify predictors of love for spouse. Although relationship satisfaction probably is the strongest predictor of love, the psychological wellbeing and subjective loneliness also matters. 387 couples with marriage duration from six months to 50 years were studied. Methods: Rubin’s love and liking scale; Psychological wellbeing scale (Ryff), Loneliness scale (Russell et al.); self-report of relationship satisfaction with cognitive (satisfaction, desire to maintain marriage, divorce) and emotional (negative feelings, tension, fear of parting) issues. Dispersion, correlation, factorial and regression analysis were used. Results: Men’s love is stronger than women’s one and more stable throughout marriage. The lowest relationship satisfaction and the most pronounced love were found in 3–7 years of marriage. Common predictors of love for a partner are relationship satisfaction and the partner’s psychological wellbeing; a specific predictor for men is a low level of subjective loneliness, and for women it is the husband’s love for her, his subjective loneliness and her fear of parting. Spouses who express a desire to divorce are characterized by weak love for a partner, men are not satisfied with the relationship and both spouses have a reduced level of psychological wellbeing: women are not competent enough, men have difficulty setting life goals, and both partners have low self-acceptance.
Life satisfaction of elderly women and men
Authors:   Institute of Psychology of the Russian Academy of Sciences, Nikitina Elena
Published: May 2024

The article presents the results of an analytical review of modern publications and an empirical study of life satisfaction among women and men of elderly and senile age. The problems of studying life satisfaction and psychological well-being among older respondents, related to the formation of gender-balanced samples and the selection of adequate instruments, are noted. The results of studies of the examined characteristics in women and men, as well as in representatives of different age groups, are demonstrated. Unique factors of psychological well-being in different samples are shown. Elderly respondents noted a greater importance of health, prosperity and peace in the family, a positive attitude towards themselves and others, as well as spirituality, compared to younger respondents who were more focused on self-development and activity. A distinctive feature of this work is the comparison of the results in two groups equalized by age, level of education, professional and family status, which included 36 women and 36 men aged from 64 to 89 years. When comparing the results of these groups, differences were found only in emotional support and self-esteem of character. Life satisfaction in old and senile age does not differ between men and women, but it is associated with different variables. For women, the indicators that reflect the success of social interaction — emotional and instrumental support and self-esteem of character are the most important. Self-esteem of appearance at this age is not a resource for life satisfaction. Life satisfaction among older men is related to their self-esteem and does not differ depending on social support or sociotropy/self-sufficiency, nor on involvement in family interactions. The question is raised about the effectiveness of using the Differential Loneliness Questionnaire in this age group.

Published: May 2024

The work describes the development and psychometric evaluation of a tool aimed at assessing the strategies used to promote successful aging. In the context of increasing life expectancy and the number of older people in the general population, the issue of maintaining and improving the quality of life of older people is particularly acute. Science has accumulated a large amount of data on the mechanisms and factors influencing aging. Moreover, these factors can be modeled by the person himself. However, there are no tools that would allow us to assess these mechanisms and the frequency of their use in a one’s life, both current and retrospectively. The study participants included 170 adults aged 40–75 years. Based on theoretical analysis, 22 strategies were formulated, each of which was assessed on a 5-point scale. To check the convergent validity, the Health-Promoting Lifestyle Profile questionnaire, the K.Riff Psychological Well-Being Scale, the Aging Perception Questionnaire, and questions from a demographic survey were used. As a result of exploratory factor analysis, four scales were identified: “Strategies for maintaining health”, “Metacognitive strategies”, “Strategies for self-development” and “Generative strategies”. Scale reliability and confirmatory analysis confirmed the suitability of the resulting instrument as well as its consistency with the empirical data. Analysis of convergent validity showed that the selected scales were associated with indicators of a healthy lifestyle, psychological well-being, positive ideas about aging and the desire to change something in one’s life for the sake of a prosperous old age. The results obtained can be used both for scientific study of the mechanisms of futurization of aging, and for practical work on assessing resources for the formation of aging and building individual aging trajectories.

The article is dedicated to the memory of Professor of the Department of Medical Psychology and Psychophysiology of the Saint Petersburg State University, a leading specialist in the field of child clinical psychology Irina Ivanovna Mamaychuk. An attempt to analyze and generalize its great scientific and practical contribution to child clinical psychology is made. The stages of her professional path are singled out and described: (1) the study of the mechanisms and types of disturbed development in children with cerebral palsy; (2) study of the psychology of children with various disorders of the musculoskeletal system; (3) empirical substantiation of strategies and technologies for psychological assistance to children with various variants of disturbed development; (4) development of methodological and applied problems of child clinical psychology. The results and conclusions of Irina Ivanovna’s key studies are revealed, which have made a great contribution to understanding the causes and mechanisms of mental disorders in children and adolescents, and embodying the principles of ontogenetic and system-structural approaches developed at the Leningrad — St. Petersburg school of psychology. In particular, the study of the role of motility in perceptogenesis in various variants of dysontogenesis; specifics of violations of interfunctional relationships in children with motor and mental disorders; subspecies of mental retardation of cerebral-organic origin; psychological characteristics of children and adolescents with somatic pathology. Based on the analysis of scientific works, a list of the main problems and prospects of modern child clinical psychology is highlighted. An approach to psychological assistance and psychological correction of disorders in children and adolescents is described, taking into account the role of the family and the immediate environment. It is emphasized that the empirical work of Irina Ivanovna has become the “gold standard” in the study of the problems of children with mental dysontogenesis, and her theoretical generalizations and methodological developments are very important а for the further development of child clinical psychology and understanding the problem of mental development in general.
National museums of communication and postal service in postal miniature of Germany, France and Russia
Authors:   St. Petersburg State University, Metelkin Evgeny N. , Sokhor Tatiana E. ,   St. Petersburg State University
Published: May 2024

In the second half of the 19th century, almost simultaneously with the establishment of the Universal Postal Union (UPU) in 1874, postal museums began to open across Europe. The first postal museums opened in the UPU founding countries — Germany and Russia. The objectives and concepts of these museums were presented differently to their organizers. In Germany they tried to cover the history of the world mail, in Russia — the development of telegraph, as the most modern means of communication, and France — demonstrated a desire to become the capital of typology. The creation of postal museums, which were seen not only as cultural phenomena but also as a national strategic element, also involved national governments (or their departments). The Second World War changed not only philatelic themes, but also influenced changes in display activities. Today there are postal museums in virtually every country in the world, but not every philatelic production reflects the stages of their creation and development. Images of world postal museums, their creators and exhibits in the Timbrology media space emphasize that postage stamps, in addition to their main purpose — payment for postal messages, perform supplementary functions — advertising and educational.
Archaeological monuments of Ancient Egypt in the collection of V. S. Golenishchev (based on the materials of card index)

Published: May 2024

This paper continues study of the unpublished archival material kept in the Department of Ancient Orient at the State Pushkin Museum of Fine Arts. The aim of this publication is to put into scientific use the provenance data written by Golenischeff’s hand on Egyptian objects from his own collection. In present paper we analyse the information from the so called ‘fichiers’ (cards) indicating the strict location, from which the object comes. The purchase of an object at some place did not mean, however, the same geographical provenience of an object. Sometimes Golenischeff indicates this provenance from dealers’s words. The cards also bear indirect references (Latin cf. and French à comparer — “to compare”) to many geographical locations, and to the publications of outstanding researchers of that time (W. M. Flinders Petrie, G. Quibell, E. Naville et al). Consequently, we may suppose the same provenance for these ‘compared’ (i. e. analogous) monuments. Occasionally the information about the purchases is combined with details about the dealers (legal antiquarians or illegal diggers). In this paper we also add the information from the Golenischeff’ notebooks kept in Paris and from the archaeological reports (one of them is a newly published material). A unique evidence gives us the inscriptions made by Golenischeff’ hand (in black ink or graphite pencil) on the surface of some ceramic. So far, we are aware of 8 such objects (in one case there is a paper sheet with an indication of geographical site).

Published: May 2024

The article considers the museum education of students (on the example of educational, museum practice) at the university, which is an integral part of the general culture of modern youth and is based on the experience of communication with museums in the family and school. Educational museum practice at the Institute of History and Sociology of the Udmurt State University of Izhevsk (direction of training 46.03.01 “History”, bachelors) has a purpose and objectives, stages, program and base of conduct. The results of the students’ museum practice in the field of formation of theoretical knowledge, practical skills, development of professional competencies are presented. The experience of conducting is summarized and certain problems are identified both in the organization of educational practice by the university (per diem and the amount for accommodation in practice, the choice of a museum as a place of practice, mutually beneficial cooperation “university to museum”, “museum to university”), and in the implementation of students’ activities in various departments of museums. The idea is expressed about the prospects of the work of students-historians during the internship at the museum, not only as museum employees, but also as volunteers (guides, fund workers, researchers, etc.) in the organization of events held by the institution. Volunteering helps students to better understand the content of the work of a particular museum, have a clearer idea of modern professions in the museum, immerse themselves in the museum space. The work of students in the field of project activities on the subject of the department, the formation of a student’s personal interest in the course work or tasks of the basic museum is relevant in educational practice.
The use of modern technical means to study the behavior of visitors in the museum
Authors:   Altai State Pedagogical University, Kiyutsina Irina S.
Published: May 2024

Since the first half of the 20th century, museums have been conducting the first systematic studies on the peculiarities of visitors’ behavior when familiarizing themselves with the exposition. In the history of the issue of studying the museum audience in Russia over the past hundred years, three key periods can be distinguished. Such milestones in Russia were the 1920–1930s, the 1960–1970s and the 1990–2000s. Museum research at these points in history is distinguished by the most significant scientific results. Today museum sociology is gaining momentum, as in the last decade the visitor is viewed as a consumer who puts forward requests, thereby forming the vector of the museum’s development. In order to get to know your target audience better, it is no longer enough to use only traditional methods of studying your visitor. When studying, it is also necessary to apply new technological means that allow obtaining more reliable data. The purpose of the author of the article: to describe new technical means (eyetracking, video analytics, heat maps) and their possibilities in the process of studying the museum audience. In the article, the author also describes a number of advantages of using modern technical means in studying the behavior of visitors. The author also examines the domestic and foreign experience of popular museums that have already used modern technological means to study their audience. As a result of his research, the author comes to the conclusion that only an integrated approach, which is expressed in a combination of traditional methods of study and the use of modern technical means, allows you to get more accurate data and find out the true needs of visitors.

Authors:   University of Douala, Ngitir Victor Bayena , Ebwa Ebwa Serge-Michaël ,   University of Douala
Published: May 2024

Of the 20 private museums recognized by the Cameroon government, the Museum of Civilizations, Dschang (Musee des Civilizations, MDC) stands out as a hub of national cultures, despite its poor visitation and low visibility. Conceived in 1996 and inaugurated in November 2010, MDC was located at the heart of Dschang town in the West Region of Cameroon (Central Africa). Its central theme is man at the heart of his cultural identity for a dialogue of civilizations. Today, MDC faces fierce challenges as it memorializes the cultures of the Fang-Beti-Bulu, Sudano-Sahelian, Grassfields and Sawa peoples of Cameroon. This paper revisits MDC among other things, as a melting pot of Cameroonian cultures and regional identities. Our central question is: “how, despite its multiple challenges, does MDC successfully memorialize Cameroon’s four principal cultural areas?” While cultural representations remain central, concerns of identity, research and the teaching of museology have also been highlighted. A blend of qualitative research, iconography and ethnography, analyzed on the basis of content, chronology and participatory observation, provide the methodological grounds for our findings. The Museum of Civilizations not only commemorates the cultures and civilizations of Cameroon and the Central African sub-region in general, but also provides an ideal hub for culture tourism, education and research.

Published: May 2024

The article deals with the history, structure and methods of work of the Nara Research Center, as well as the socio-cultural context of its establishment. Compared to many countries, the experience of preserving cultural heritage in Japan began to take shape relatively recently, but over the past period, original forms of working with heritage unique to Japan have been developed, which have expanded the world experience in this area. Familiarity with the Japanese experience can be useful for the Russian museum community and can contribute to the emergence of new forms in the domestic practice of dealing with heritage. One of the striking manifestations of the organization of cultural heritage conservation in Japan is the activity of the National Research Institute in Nara. There are currently no works in the domestic literature devoted to the analysis. Since the 50s of the 20th century, the Japanese government has actively begun to work in the field of preserving and protecting universal cultural values. The Nara National Research Institute is an excellent example of a government organization that is engaged in a wide range of work to preserve the country’s cultural assets, as well as scientific education and international activities. The work of the National Research Center is a striking example of a well-functioning system for the protection of cultural property operating in Japan at the state level. The competence of the center includes not only conducting excavations, but also analyzing the extracted materials, extensive educational, educational and international security activities. The data obtained during the research is carefully structured and digitized and will be made publicly available through several public databases created for a detailed study of issues related to archeology and related sciences.

Authors:   St. Petersburg State University, Krapivin Mikhail Yu.
Published: May 2024

Bodies of the Cheka — GPU — OGPU for many years collected and analyzed information about the processes that took place in various social strata, national, confessional, professional groups (in certain regions and across the country as a whole). The efforts of the Chekists were aimed at curbing covert and open opposition to Soviet power on the part of political opponents of the regime. Among other things, the authorities were interested in the mindset among civil servants, as well as among the scientific and creative intelligentsia. On April 29, 1920, the Presidium of the All-Russian Extraordinary Commission issued order No. 54, addressed to the territorial bodies of the Cheka, with instructions to collect data on the activities of the provincial commissions “for the protection of monuments of art and antiquity”. The Chekists, first of all, were interested in information about the connections of museum employees with the clergy and teaching staff of the former religious educational institutions. Below is a list of information provided by employees of the Novgorod provincial Cheka and sent by them in parallel to the Secret Department of the Cheka and to the VIII Department of the People’s Commissariat of Justice of the RSFSR. The publication is carried out according to the original copy deposited in the A-353 fund of the State Archive of the Russian Federation. The document is accompanied by detailed comments, in particular, information about the employees of Novgorod museums: A. V. Nikiforovsky, S. K. Matveevsky, V. A. Kvashonkin and others. Particular attention is paid to the ups and downs of the biography of N. G. Porfiridov, a landmark person in the and one of the defendants in a large-scale criminal case initiated in January 1933 by employees of the Plenipotentiary Representation of the United State Political Directorate in the Leningrad Military District against a large group of people, including museum workers and local historians.
Identifying challenging barriers to farmers' adaptation to climate change in Bo district, Sierra Leone: A review
Authors: Alie Morie Elogima Kendekpa , Yateh Mohamed , Bavumiragira Jean Pierre , Liao Zhenliang
Published: May 2024

The global trend of climate change presents substantial obstacles to the agricultural sector in Africa, impacting farmers’ livelihoods and jeopardizing food security. Sierra Leone, similarly to numerous other African nations, confronts substantial obstacles in effectively responding to the consequences of climate change, with a special emphasis on the agricultural domain. The article examines the formidable obstacles farmers face in Sierra Leone as they strive to adjust to the impacts of climate change. A detailed literature review and empirical evidence identify four main barriers: economic, knowledge and information, institutional and policy, and social and cultural aspects. Farmers face economic problems investing in adaptable technologies and recovering from climate-related losses due to restricted financial resources, financial institution availability, and insurance coverage. Limited access to reliable climate data and scientific research hinders informed decision-making and adaptive strategy prioritization. Institutional and policy challenges, including limited institutional capacity for climate change adaptation planning and implementation and policy gaps and inconsistencies, hinder farmers’ climate adaptation efforts. Social and cultural variables, including traditional attitudes and traditions, also resist change and impede climate-resilient actions. Financial support, targeted extension services, farmer-to-farmer learning, enhanced institutions, policy integration into agricultural policies, and community engagement are suggested.
Green infrastructure layout based on a dynamic operation feature of drainage systems
Authors: Shen Chen , Dong Xin , Wang Luyao , Wang Xinhao
Published: May 2024

Increasingly frequent urban floods strain the traditional grey infrastructure, overwhelming the capacity of drainage networks and causing challenges in managing stormwater. The heavy precipitation leads to flooding and damage to drainage systems. Consequently, efficient mitigation strategies for flooding have been researched deeply. Green infrastructure (GI) has proved to be effective in responding the increasing risk of flood and alleviate pressure on drainage systems. However, as the primary infrastructure of stormwater management, there is still a lack of attention to the dynamic operation feature of urban sewer systems during precipitation events. To fill this gap, we proposed a novel approach that integrates hydraulic characteristics and the topological structure of a sewer network system. This approach aims to identify influential nodes, which contribute to the connectivity of the sewer network amidst dynamic changes in inflow during precipitation events. Furthermore, we adopted rain barrels to serve as exemplars of GI, and 14 GI layout schemes are produced based on the different ranks of influential nodes. Implementing GI measures on both poorly performing and well-performing nodes can yield distinct benefits in mitigating node flooding. This approach provides a new perspective for stormwater management, establishing effective synergy between GI and the drainage system.

Published: May 2024

Cervical lymph node metastasis is an important determinant of cancer stage and the selection of an appropriate treatment plan for patients with
head and neck cancer. Therefore, metastatic cervical lymph nodes should be effectively differentiated from lymphoma, tuberculous lymphadenitis,
and other benign lymphadenopathies. The aim of this work is to describe the performance of Doppler ultrasound and superb microvascular imaging
(SMI) in evaluating blood flow information of cervical lymph nodes. In addition, the features of flow imaging in metastatic lymph nodes,
lymphoma, and tuberculous lymphadenitis were described. Compared with Doppler ultrasound, SMI, the latest blood flow imaging technology,
could detect more blood flow signals because the sensitivity, specificity, and accuracy of SMI in the diagnosis of cervical lymph node disease were
higher. This article summarizes the value of Doppler ultrasound and SMI in evaluating cervical lymph node diseases and focuses on the diagnostic
performance of SMI.

Authors: Dissanayake Dinusha Shiromala , Jayawardena Thilina Uduwaka , Asanka Sanjeewa Kalu Kapuge
Published: May 2024

Functional foods are foods with therapeutic properties that enhance health
along with nutritional properties. This review provides information about the potential
of using marine ingredients to develop functional foods by elaborating on the
nutritional and therapeutic effects of bioactive compounds found in marine
bioresources. Microalgae, marine fungi, bacteria, marine invertebrates, vertebrates, and
marine plants are marine resources, and some of the bioactive compounds obtained
from marine resources are polysaccharides, fatty acids proteins, peptides, amino acids,
many types of essential macro and trace elements, pigments, and phenolic compounds.
Marine bioactive compounds have shown many therapeutic properties, including
anticancer, antimicrobial, antioxidant, anti-proliferative, anti-inflammatory, antidiabetic, and immune regulatory activities. These compounds can be used in the
functional food industry in the form of nano or micro-particles, liposomes, gels,
liquids, solids, pastes, and emulsions to overcome the challenges that could occur
during product formulation and processing. Overall, this book chapter reveals the
important facts about marine bioresources (except Seaweeds) and their functional
potentials that the majority are unaware of. It also identifies that future research studies
should be carried out.

Published: May 2024

Several functional proteins are identified and extracted from seaweeds. Red
seaweeds contain a higher amount of proteins compared to green and brown seaweeds.
Based on the structure, functional proteins in seaweeds can be categorized as
glycoproteins and lectins, phycobiliproteins, mycosporine-like amino acids, and
peptides and hydrolysates. Glycoproteins are oligosaccharides (glycans) bound to the
proteins with N-glycosylation or O-glycosyl linkages. Lectins are also a type of
glycoprotein with a carbohydrate-binding domain that binds to specific sugar residues.
Phycobiliproteins (PBP) are water-soluble fluorescent pigments mostly found in red
seaweeds. There are several types of phycobiliproteins, such as phycoerythrin,
phycocyanin, phycoerythrocyanins, and allophycocyanin. Mycosporine-like amino
acids (MAA) are secondary metabolites produced by marine organisms, including
seaweeds. Peptides and hydrolysates are produced by gastrointestinal digestion or
hydrolyzation processes. Several studies suggested that seaweed functional proteins
exert unique health benefits, including antioxidant, anti-obesity, antimicrobial and
antihypertensive activities. In this chapter, we will briefly describe the bioactive
properties of proteins isolated from seaweeds.

Data curah hujan merupakan data yang sangat penting dalam pengelolaan sumber daya air, sehingga dibutuhkan data curah hujan yang baik, akurat, runtut dan panjang. Namun, ketersediaan data curah hujan di Indonesia masih kurang baik. Persebaran stasiun yang tidak merata, serta banyaknya terjadi kehilangan data, terutama pada daerah-daerah terpencil. Salah satu alternatif untuk menyelesaikan permasalahan kekurangan data tersebut adalah dengan memanfaatkan data dari satelit curah hujan. Dalam menggunakan data curah hujan satelit, harus dilakukan evaluasi terlebih dahulu. Penelitian ini dilakukan untuk mengevaluasi keandalan satelit ERA-5 pada periode bulanan, 15-harian, dan 10-harian di Sub DAS Bodor. Evaluasi dilakukan menggunakan 3 parameter statistik yaitu NSE, RSR, dan r. Hasil evaluasi menunjukkan bahwa satelit ERA-5 memiliki nilai paling andal pada periode bulanan di Sub DAS Bodor (NSE: 0,904; RSR: 0,310; r: 0,952),  disusul oleh periode 15-harian (NSE: 0,754; RSR: 0,496; r: 0,875),   dan periode 10-harian (NSE: 0,588; RSR: 0,642; r: 0,774).

Authors: Secilia Melinda Priskila , Bisri Mohammad , Andawayanti Ussy
Published: May 2024

Site Gurimbang Mine Operation (GMO) ialah site penambangan oleh PT Berau Coal yang menerapkan metode penambangan terbuka. Metode ini akan menyebabkan terbentuknya cekungan yang luas sehingga berpotensi menjadi daerah tampungan air saat terjadi hujan. Air tidak dapat dialirkan di luar wilayah dapat menggangu kegiatan operasional penambangan, oleh karena itu aspek hidrologi harus sangat diperhatikan. Evaluasi sistem drainase di GMO sejauh ini menggunakan software HEC-RAS untuk menghitung kapasitas tampung salurannya. Studi ini ditujukan untuk melakukan pemodelan software SWMM sebagai terobosan baru dalam melakukan evaluasi sistem drainase. Dilakukan evaluasi terhadap kapasitas tampung saluran ditinjau dari teknologi drainase yang digunakan dan kerapatan aliran memanfaatkan pemodelan software HEC-RAS 6.2 serta SWMM 5.2. Serta analisa perbandingan hasil running simulasi antara HEC-RAS dan SWMM, sehingga nantinya dapat diketahui kekurangan dan kelebihan dari kedua software tersebut. Kedua software tidak menunjukan kapasitas saluran drainase dengan skala angka, namun kedua software tersebut menggambarkanya dalam bentuk simulasi yang berbeda pada setiap titik saluran yang dimodelkan. Pada HEC-RAS fitur view disajikan melalui fitur view cross section, view profiles, view 3d multiple cross section plot. Sedangkan pada SWMM terdapat fitur view profiles, view time series plot, fitur halaman map,dan fitur query. Hasil running kedua software tidak dapat dibandingkan karena menghasilkan tabel dengan output yang berbeda. hasil running simulasi software HEC-RAS saluran dinyatakan aman pada saat nilai W.S. Elev (elevasi muka air saluran) dibawah nilai Ground (elevasi tinggi tanggul saluran). SWMM menyatakan saluran aman atau tidak meluap ketika nilainya Max/Full Depth (tinggi maksimum saluran hasil simulasi) tidak melebihi dari tinggi saluran eksisting, atau bisa juga dilihat melalui fitur query Namun dari berbagai kelebihan yang ditawarkan oleh SWMM dapat disimpulkan bahwa secara penggunaan SWMM jauh lebih praktis dari pada HEC-RAS dalam memodelkan sistem drainase tambang yang ada.

Bendungan Manggar adalah bendungan tipe urugan tanah homogen yang dilengkapi dengan chimney drain yang dihubungkan dengan horizontal blanket drain. Puncak bendungan diperkeras dengan paving beton dan pada tahun 2019/2020 puncak bendungan dipekeras dengan aspal, lereng hulu diberi perlindungan blok beton (semula didesain dengan rip-rap batu) dan lereng hilir dilindungi dengan gebalan rumput dan sistem drainasi permukaan. Pada tumpuan kanan, saat penggalian pondasi bendungan ditemukan adanya lapisan pasir halus sehingga galian pondasi dibuat menjorok masuk kedalam bukit tumpuan. Karena lapisan pasir halus cukup tebal dan tidak dapat dibuang seluruhnya, untuk menghindarkan terjadinya rembesan yang berlebihan, lereng hulu bendungan dipasang blanket kedap air dari tanah lempung. Penentuan besaran gempa desain bendungan mengikuti pedoman pada “Pedoman Pd- T- 14-2004 A” Analisa Stabilitas Bendungan Urugan akibat Gempa dimulai dengan menentukan faktor risiko keamanan bendungan. Stabilitas terhadap aliran filtrasi dengan SEEP/W menunjukkan debit rembesan, gejala buluh, dan gejala sembulan aman. Stabilitas lereng metode Bishop dengan SLOPE/W menunjukkan kondisi statis, OBE 100, dan MDE 5000 aman
