Published: August 2022

Effective and efficient water resources management is unquestionably required to meet the high demand of water to support rapid population growth and socio-economic expansion. The water supply availability is slowly decreased due to plantation land clearing, construction projects, and land-change activities in the watershed area. This study aimed to analyze the sustainability of irrigation management in Bali and outside of Bali (Bolaang Mongondow Regency, North Sulawesi). Primary and secondary data were employed in this study. In-depth interview and focus group discussion sessions conducted to collect the primary data. The literature review technique applied to gather secondary data to support the study result and discussion. We recruited the committee of subak, farmers, and stakeholders or policymakers from the Local Board of Agriculture and Public Works and Public Housing (sub-irrigation division) to participate in this study. Multi-Dimensional Scaling method employed to analyze the study data. Results revealed that the sustainability prospective of the irrigation system management in Mongondow was relatively weak, especially on the physical-ecological, infrastructure-technology, and policy-institutional dimensions. However, we noticed that the economy and social dimension of the watershed area was relatively sustainable. Contrary situations were found on Saba Watershed in Buleleng Regency, Bali Province. We found that the sustainability prospective on the physical-ecological and infrastructure-technology dimension was relatively weak. But the dimension of the economy, socio-cultural, and policy-institutional was adequately sustainable.

The main problem in this research was the conversion of agricultural land into non-agricultural land in the regional spatial plan. The occurrence of agricultural land shifting involved the government, land owners, investors and the community. The aims of this research was to analyze factors, economic, social, land conditions and the government as the reason of the conversion of agricultural land into non-agriculture. The research was conducted in Denbantas Village, Tabanan Regency, Bali, with the consideration that the village was shifting the function of agricultural land. The research sample was determined by proportional random sampling with total 148 respondents. The data were analyzed quantitatively and qualitatively, the research results found that the dominant factors of agricultural land shifting were the need for housing, public ignorance of the land function, there was no land as an alternative to build a residence, and the government lacked socialization about land functions according to the regional spatial plan. The research on the causes of conversion of agricultural land into non-agricultural need to be conducted to anticipate land conversion did not occur sustainably

Published: August 2022

Pemerintah Indonesia dan Singapura telah menandatangani perjanjian penyesuaian Flight Information Region (FIR) pada tanggal 25 Januari 2022. FIR adalah suatu daerah yang digunakan guna pelayanan penerbangan dan pelayanan kesiagaan diberikan. Dengan adanya penandatanganan perjanjian penyesuaian ini maka FIR di atas Kepulauan Riau dan Natuna yang sejak tahun 1946 dikuasai oleh Singapura diambil alih oleh Indonesia. Muncul pro dan kontra terhadap penandatanganan perjanjian tersebut maka dalam artikel ini akan dibahas mengenai peluang dan tantangan terhadap penandatanganan perjanjian tersebut. Penelitian ini akan menggunakan metode penelitian yuridis normatif yaitu penelitian hukum dengan menggunakan data sekunder melalui penelusuran terhadap peraturan dan literatur yang berkaitan dengan permasalahan yang akan diteliti. Hasil penelitian menunjukan bahwa dengan ditandatanganinya persetujuan penyesuaian batas FIR mempertegas kedaulatan udara yang dimiliki Indonesia sebagai negara kepulauan sesuai dengan ketentuan dalam Konvensi Chicago 1944 dan UNCLOS 1982 sehingga dari segi ekonomi menambah pendapatan bagi Indonesia. Disisi lain, masih terdapat permasalahan yang ditimbulkan karena untuk jalur di ruang udara di bawah 37.000 kaki masih didelegasikan kepada Singapura selama 25 tahun. Isu lain terkait penguasaaan teknologi bahwa Indonesia harus terus mengembangkan teknologi yang dimiliki sehingga dapat mengambilalih seluruh wilayah FIR.

Amino acid composition of medicinal herbs in the Stavropol Territory
Authors: Чумакова В. , Чумаков В.
Published: August 2022

Для нормального роста, развития, репродукции, сохранения здоровья и получения максимальной продуктивности животных в кормах постоянно должно быть наличие определённого количества аминокислот. Их недостаток может быть восполнен с помощью добавок из синтетических препаратов или введением в рацион кормов с высоким содержанием недостающей аминокислоты. Цель исследований — определить содержание аминокислот в растительном сырье шести видов и сортов лекарственных растений. Установлено наличие 15 аминокислот, из них девять незаменимых. Выявлены доминирующие моноаминодикарбоновые аминокислоты: аспарагиновая и глутаминовая (от 11,31 до 39,05% от общего содержания). Незаменимые аминокислоты в суммарном выражении составляют от 39,26% в корнеплодах скорцонеры сорта Солнечная премьера до 55,17% в траве змееголовника сорта Эгоист, среди аминокислот преобладает у большинства видов и сортов лейцин: от 5,36% — у скорцонеры до 9,94% — у лофанта анисового сорта Премьер. Результаты изучения аминокислотного состава видов и сортов лекарственных растений могут быть использованы при составлении рационов кормления животных с возможностью получения единовременно терапевтического эффекта.

Optimal growth, development, reproduction, health and maximum productivity of livestock require regular consumption of certain amount of amino acids in forage. Amino acid deficiency can be restored with artificial additives or feeds, containing high concentration of a respective amino acid. The goal of the investigation was to determine amino acid content in plant materials of six species and varieties of medicinal herbs. The experiment found 9 essential amino acids out of total 15 acids, presented in plan samples. Aspartic and glutamine acids were prevalent (from 11.31 to 39.05% of the total amount). Total content of essential amino acids made up from 39.26% in roots of black salsify “Solnechnaya” to 55.17% in dragonhead “Egoist”. Most genotypes had high concentration of leucine: from 5.36% — in black salsify to 9.94% — in giant hyssop “Premer”. The results obtained can be used for livestock diet development to provide additional medical treatment.
MPI+OpenMP implementation of conjugate gradients method with preconditioner of the block incomplete inverse triangular decomposition of the first order
Authors: Милюкова О.Ю.
Published: August 2022

В работе рассматривается предобусловливатель блочного неполного обратного треугольного разложения первого порядка “по значению” BIIC-IC1 для решения систем линейных алгебраических уравнений с симметричной положительно определенной матрицей. Рассматривается способ применения MPI+OpenMP технологии для построения и обращения предобусловливателя BIIC-IC1, при этом в предобусловливателе число блоков кратно числам используемых процессоров и используемых потоков. Предлагается способ применения MPI+OpenMP технологии для построения и обращения предобусловливателя BIIC-IC1, в котором для применения OpenMP технологии используется специальное упорядочение узлов сетки внутри подобластей, соответствующих расчетам на процессорах. Проводится сравнение времени решения задач методом сопряженных градиентов с предобусловливателем BIIC-IC1 с использованием MPI и гибридной MPI+OpenMP технологии на примере модельной задачи и ряда задач из коллекции разреженных матриц SuiteSparse.

The paper considers the preconditioner of the block incomplete inverse triangular decomposition of the first order “by value” BIIC-IC1 for solving systems of linear algebraic equations with a symmetric positively defined matrix. A method of using MPI+OpenMP technology for constructing and inverting the BIIC-IC1 preconditioner, in which the number of blocks in the preconditioner is a multiple of the number of used processors and used threads, is considered. A method is proposed for using the MPI+OpenMP technology to construct and invert the BIICIC1 preconditioner, in which a special ordering of grid nodes within subdomains corresponding to processor calculations is used to apply the OpenMP technology. The time of solving problems by the conjugate gradient method with the BIIC-IC1 preconditioner using MPI and hybrid MPI + OpenMP technology is compared on the example of a model problem and a number of problems from the collection of sparse matrices SuiteSparse.
Bioinspired gradient stretchable aerogels for ultrabroad-response-range wearable pressure sensors
Authors: Zhang Xiaoyu , Hu Zhenyu , Liang Xing , Sun Qi , Huang Jia , Zu Guoqing
Published: August 2022

With the increasing demand for electronic skin, health management, and extreme pressure monitoring, development of broad-response-range flexible pressure sensors is in urgent need. However, the reported flexible pressure sensors usually show a narrow detection range. It’s a great challenge to achieve a broad detection range of 1 Pa-10 MPa for a flexible pressure sensor. Herein, unprecedented bioinspired wearable pressure sensors based on highly stretchable reduced graphene oxide/polyurethane foam composite aerogels with modulus-gradient porous structures have been reported. A hot pressing method is applied to increase the modulus and compressive strength of the high-modulus layer of the aerogel, which ensures their compressibility at high pressures and significantly enhances the upper detection limit. Benefiting from their unique superelastic (90-99% reversible strain) and gradient structures with the gradient modulus spanning from 5.4 kPa to 430 kPa and gradient compressive stress (at 90% strain) spanning from 25 kPa to 37 MPa, the resulting pressure sensors exhibit a record-breaking detection range of 1 Pa-12.6 MPa. In addition, the pressure sensors can withstand 10000 cycles at a high pressure of 1 MPa, which can’t be achieved by traditional flexible pressure sensors. This work provides a versatile and powerful strategy towards next-generation high-performance broad-response-range flexible electronics.
Thirteen-Step Chemoenzymatic Synthesis of Gedunin
Authors: Li Jian , Chen Fang , Renata Hans
Published: August 2022

The limonoids have attracted significant attention from the synthetic community owing to their striking structural complexity and medicinal potential. Recent efforts notwithstanding, synthetic access to many intact or ring-D seco limonoids still remains elusive. Here, we report the first de novo synthesis of gedunin, a ring-D seco limonoid with HSP90 inhibitory ac-tivity, that proceeds in thirteen steps. Two enabling features in our strategy are the application of modern catalytic transformations to set the key quaternary centers in the carbocyclic core and the application of site- and chemoselective enzymatic oxidation to establish the requisite oxidation pattern on the A ring. This work lays the foundation for efficient synthetic access to other limonoids and unnatural analogs to facilitate further pharmacological investigation of the family.
Analysis of the Pb0.30CaxSryTiO3 ternary system: The effect of Ca2+ and Sr2+ cations on the electrical properties of PbTiO3

Published: August 2022

Powder and thin films of the Pb0.30Ca0.10Sr0.60TiO3 (PCST 30/10/60) and Pb0.30Ca0.60Sr0.10TiO3 (PCST 30/60/10) ternary system were synthetized by the polymeric precursor method and the thin films deposited on the Si/SiO2/Ti/Pt substrate. The effects of the Sr2+ and Ca2+ cations substitutions on the electrical and structural properties of the PbTiO3 were characterized by X-ray diffraction, Infrared, and Raman spectroscopy. Theoretical calculations were performed using the CRYSTAL06 program associated with the density functional theory and the B3LYP functional hybrid. Structural and electronic properties of the system were analyzed. The�band gap values calculated for the PCST 30/10/60 and PCST 30/60/10 models were 3.35 and 3.41 eV, respectively. The results showed an evolution to a greater symmetry in the direction to the cubic SrTiO3 structure and the phase transition was characterized by the Curie temperature dependence. The broad bands above FE-PE phase transition temperature suggest a phase transition diffuse type. It is explained by a local symmetry disorder due to a higher Sr2+ and Ca2+ cations concentration in the PbTiO3 host lattice.

Published: August 2022

Thermal and rheological characterizations were performed on prepreg produced with two different commercial epoxy resins - M21� and 8552� � aiming to study and optimize the curing cycle of structural components used in aerospace industry. Characterizations were performed by differential scanning calorimetry (DSC), rheology and dynamic mechanical analysis techniques were assessed and the results were correlated and supported by Fourier Transform Infrared spectroscopy. Additionally, to heating rates suggested by the material supplier, DSC analysis allowed to evaluate further heating rates: 2, 5, 10, 15 and 20 �C/min. Materials presented the n fractional order kinetic of cure and have in its formulation the presence of thermoplastics, in addition to epoxy and amine. Results confirmed that the best heating rates for processing both materials are the lower ones, as they result in a better control of the reactions between chemical compounds involved and the physical changes that are part of curing process stages. Results have analytically confirmed the suggested proposal for curing cycle from supplier is the best choice for materials involved.

Authors:   Universidade do Contestado - UNC, Backes Jênifer Cristina , Leão André ,   UFRGS, Rech Julio Cesar , Rech Aline Schuck
Published: August 2022

The use of biocementation is a technique widely used in the civil construction to repair pathologies, such as cracks and fissures. This technique is linked to the bacterial activity (urolytic and/or carbonategenic), responsible for the conversion of urea into carbonate, correcting problems in the structure. In this sense, the aim of this study was to identify the main ureolytic bacteria capable of precipitating calcium carbonate in mortar, one of the most widely applied construction areas, as well as to evaluate the performance of each microorganism in changing the physical and mechanical properties of the mortar. For this, a bibliographic search was carried out in the database of Scopus, Scielo, Web of Since, as well as in the academic portal of CAPES. The results show that the main bacteria associated with the mortar biocementation technique is the genus Bacillus sp. Parameters and standards for evaluating the performance of the different bacteria used between the studies were not identified. However, evaluations related to mortar strength were present in the vast majority of researches. The use of biocementation via bacterial activity proved to be an important strategy that promotes improvements in strength, compression, water absorption potential and porosity of the mortar

Published: August 2022

Nowadays, watching films at home is one of people's entertainment. Netflix is a service provider for watching films and provides many types of film genres. However, of the many films available, it makes users confused to choose which film to watch first. The solution to the problem is a system that provides recommendations for the best films to watch based on user ratings. Twitter is still people's favorite social media to express their feelings, thoughts, and criticisms. In this system, tweets serve as input data that will be processed into data with rating values. This research implemented a recommendation system based on user ratings from tweets using collaborative filtering combined with Support Vector Machine (SVM) classification and implemented it on user-based and item-based. The test results in this study show that Collaborative Filtering gets the best RMSE value results on item-based 0.5911 and 0.8162 on user-based. The Support Vector Machine (SVM) classification algorithm using hyperparameter tuning produces item-based values with a precision of 85.03% and recall of 90.71%, while user-based values with a precision of 87.75% and recall of 88.95%.

Authors: Oktavia Anggraini Dwi , Rohmawati Lydia
Published: August 2022

The spread of diseases caused by bacteria seriously threatens human health. Alternative materials with antibacterial effects are needed to overcome this problem, such as Fe3O4/ZnO. This study aims to determine the activity of the antibacterial inhibition zone on Fe3O4/ZnO nanocomposites. The Fe3O4/ZnO nanocomposite fabrication used the ultrasonication wave method. Characterization was performed using X-ray diffraction (XRD), Fourier Transforms Infrared (FTIR), and antibacterial activity tests. The results of the XRD analysis showed that the average crystal size was about 42 nm for Fe3O4, 36 nm for ZnO, and 39 nm for Fe3O4/ZnO. The FTIR results on the nanocomposite showed the characteristics of the Fe-O group at the absorption peak of 874.93 and 691.29 cm-1, while at 436.56 cm-1 indicated the presence of Zn-O compound bonds. The Fe3O4/ZnO nanocomposite with a weight ratio (1:10) showed good effectiveness in inhibiting S. aureus and E. coli bacteria at concentrations of 0.8 mg/m and 1 mg/ml. Meanwhile, in E. coli bacteria, the average diameter of the inhibition zone was relatively low. Thus Fe3O4/ZnO nanocomposite has the potential to be applied in antibacterial applications
Interdisciplinary Walks: Investigating the benefits of walking for research
Authors: McKay Anna
Published: August 2022

The Interdisciplinary Walks project was funded by the Leicester Institute for Advanced Studies (LIAS) between May and July 2022. It set out to encourage staff members to think outside their own disciplinary silos whilst getting familiar with University of Leicester surroundings, from the main and north campus to the School of Business at Brookfield, and the Space Park. Consultations with 29 members of staff asking about their interdisciplinary research and favourite walks were conducted via Zoom and recorded for use on the WordPress site . Intended outputs from the Interdisciplinary Walks project included an A5 map booklet (with a print run of c.500 copies) drawn by illustrator Amy McKay, web content including edited audio recordings of consultations and accompanying transcripts, and six visualisations of the audio clips created by visual storytelling agency Nifty Fox Creative. This working paper provides an overview of the project as it progressed, with the final sections reflecting upon the benefits and challenges of interdisciplinary research and the value of walking and thinking as viewed by academic researchers. The consultations recognised the importance of access to parks and green spaces, and identified four key walking behaviours: walking alone, together, to disconnect, and to focus. The project concludes that by understanding individual preferences in how we walk, researchers can harness the potential of walking as a tool to improve mind, body, and research.
The Impact of the COVID-19 Pandemic on the Career Preparedness of Chemistry Graduates
Authors: Ladwa Abhishek , Williams Dylan P. , Blackburn Richard A. R.
Published: August 2022

Recent research has established that the COVID-19 pandemic has resulted in a shift in University student expectations of their graduate prospects due to unavoidable changes in their learning experiences during the pandemic, as well as the decrease in number of available jobs because of the economic impact of measures put in place to reduce COVID-19 transmission. This study used a survey to investigate: (a) the impact of the pandemic on student destinations six months after graduation and (b) the variations in perceptions of personal level of career preparedness between pre-pandemic graduates and graduates at different stages of the pandemic (i.e. the graduating classes of 2020 and 2021). 40 University of Leicester chemistry graduates engaged with the survey and analysis of the data revealed a non-statistically significant negative impact on employment six-months after graduation that appears to only affect graduates in 2020. The data also suggests that increased experience of the blended learning approaches adopted at the University of Leicester during the pandemic studies may better prepare graduates for remote working practices (e.g. using remote video conferencing software).

Breast cancer is a life-threatening disease among Indonesian women. The etiology of breast cancer is still uncertain, and therefore adequate primary prevention is difficult. Early diagnosis improves cancer prognosis while also reducing medical costs, substantially reducing mortality rates. Knowledge and awareness of breast cancer risk factors and their screening may help women take preventive measures. The community service program aimed to assess the level of understanding of undergraduate medical students on breast cancer and breast self-examination (BSE). It was a one-group pretest-postest quasi-experimental study to measure the level of knowledge of 100 medical students in Indonesia from August 20th, 2020, to February 27th, 2021. The participants were asked 36 questions, which was an adaptation of previous questionnaires. A mini-lecture managed the program that focuses on risk factors and early detection. Furthermore, pretest and post-test were conducted to analyze the knowledge level before and after the dissemination. The participants included in this study were mostly 20 years and above (62%). The average recognition of breast cancer and its early detection was not high. The knowledge of breast cancer among medical students was found to be moderate. The efficacy of dissemination among medical students was apparent in knowledge change. However, good cancer awareness, especially breast cancer, needs to be established and integrated through effective cancer educational programs in the medical curricula. Hence, modification of the medical curriculum through extensive training on breast cancer preventive measures and early diagnosis is required.

Published: August 2022

Garbage is solid waste consisting of organic and inorganic substances that outlived their usefulness and must be adequately managed to prevent environmental harm. The amount and types of waste are strongly influenced by the lifestyle and the type of materials we consume, and increasing household income cause an increase in the variety of waste generated. Handling and managing organic waste requires community involvement and successful household organic waste management, contributing significantly to the zero waste program. This study aims to measure the effect of waste management training on knowledge and principles of reducing, reusing, and recycling in waste management. The study was conducted from April to June 2021 in the neighborhoods around Pejanggik, Mataram village, West Nusa Tenggara province. It is a pre-experimental study involving 50 households to analyze the effects of the waste management training provided using a one-group pretest-posttest method. Before the training, knowledge and waste management principles were 22 of 50 respondents and 32 of 50 respondents, respectively. After the provision of training, the increase in knowledge and waste management principles reached 50 of 50 respondents. In conclusion, the training activity shows increased knowledge and waste management principles in households involved. Waste processing with reduce, reuse, and recycle principles can help overcome household waste problems and convert waste into products with increased economic value. Therefore, we recommend that periodic community-based waste management training involving households be held to overcome increased organic waste in households.

Authors: Damayanti Nabila , Margo Eveline
Published: August 2022

The prevalence of central obesity in Indonesia is increasing every year. Based on data released by Riskesdas in 2018, there were 31% of the population aged 15 years and over suffer from central obesity, where the highest was found in the 45–54 years group (42.3%), followed by 44 years (39.2%) and 55–64 years group (39.1%). Central obesity can be measured by waist circumference or abdominal circumference, and it plays an important role in the occurrence of cardiovascular disease. Examining C-reactive protein (CRP) at low levels using high-sensitivity CRP (hs-CRP) methods will help to predict the risk of coronary heart disease. This study aimed to find the correlation between waist circumference and hs-CRP serum levels between the ages of 35 and 64. The study was an analytical observational with a cross-sectional approach attended by 25 respondents at Bhayangkara Hospital Tingkat I Raden Said Sukanto, Kramat Jati, East Jakarta, from October to November 2019. The waist circumference was measured with a metlin roll, and Prodia Laboratory took the blood to measure hs-CRP serum levels using ELISA methods. The data were analyzed using the Pearson correlation test. The results showed a correlation between waist circumference and hs-CRP serum levels with Sig. (2-tailed)=0.000 (p<0.05). There was a correlation between waist circumference and hs-CRP serum levels, which indicated that the greater the waist circumference, the higher levels of serum hsCRP would be.

Published: August 2022

The study examined the implication of a decentralized Value Added Tax system for states in Nigeria. It is a theoretical presentation that made is made of journals, articles, and data from the National Bureau of Statistics (NBS) accessed on Google Scholar Websites. A total of eighty (80) articles were accessed. Results from a theoretical review revealed that while few states in Nigeria are in favor of a decentralized VAT administration in the country, quite a number of them (States) are averse to the new VAT regime due to differences among the states in terms of volume of business activities and economic power as many of the states rely on federal allocation. The study, therefore, recommends Partial Decentralization (PD) of VAT administration in Nigeria as a measure of autonomy for states that will guarantee fairness in resource control in the Nigerian Society.
