Authors: Riyandy Hady , Ilham  , Zuraida Siswanti
Published: June 2024

Material konstruksi yang diperlukan pada saat proses pembangunan sebagian besar tergolong sumber daya alam tidak terbarukan (non-renewable), seperti semen, pasir, batu, dan besi. Semua bahan baku material tersebut tersedia di alam tetapi dalam jumlah yang terbatas. Oleh sebab itu penggunaan sumber daya alam harus diimbangi agar tidak menimbulkan kerusakan alam. Salah satunya yaitu dengan menggunakan bambu sebagai material alternatif yang ramah lingkungan. Pada penelitian ini akan dibahas perencanaan struktur bangunan bentang lebar. Bangunan ini memiliki bentang terlebar yaitu 20 meter dengan bambu sebagai material utama pada bangunan ini. Pemodelan struktur menggunakan SAP2000. Data yang digunakan untuk pemodelan diperoleh dari data sekunder yang terdapat pada penelitian terkait sebelumnya. Dikarenakan bambu belum ada standar khusus terkait perhitungan ketahanan struktur maka digunakan pendekatan perhitungan struktur kayu berdasarkan SNI 7973:2013 tentang spesifikasi desain untuk konstruksi kayu. Dengan menggunakan metode Load And Resistance Factor Design (LRFD) maka diperoleh dimensi penampang bambu yang mampu menahan beban yang bekerja berdasarkan SNI 1727-2013 dan SNI 1726-2019 sebagai berikut, kolom eksterior (diameter 100 mm); Kolom interior (diameter 100 mm x 9 batang bambu); Balok eksterior (diameter 100 mm); Balok interior (diameter 100 mm x 2 batang bambu); Struktur lengkung (diameter 70 mm x 7 batang bambu); Jari-jari struktur lengkung (diameter 70 mm x 4 batang bambu). Pendekatan perhitungan struktur kayu dapat diimplementasikan ke dalam struktur bambu, namun terdapat beberapa perbedaan yang harus disesuaikan jika menggunakan pendekatan kayu untuk perhitungan bambu seperti perbedaan bentuk penampang kayu dan bambu yang akan mempengaruhi luas penampang, statis momen dan momen inersia yang terjadi pada penampang.

CORPORATE ACTS AS A MEANS OF SELF-REGULATION OF BUSINESS AND PROFESSIONAL ACTIVITIES
Authors: .KIYAZOVA A
Published: June 2024

In recent years, the mechanism of state regulation of business activity has experienced structural changes. Nevertheless, in the context of the emergence of a new model of self-regulation of business and professional activity, the sources of corporate regulation, internal acts of organizations, retain their significance and acquire additional features. Corporate acts of self-regulating organizations are usually divided into two categories. The first category covers documents that define the legal status of the organization itself, the structure of its governing bodies, the order of membership, the formation of property, responsibility, and other internal issues. These documents include the constituent documents and various regulations. Another group of corporate acts determined by the nature of the institution of self-regulation is associated with the implementation of the regulatory and rule-making function and conditioned by the development and approval of internal standards and rules. The nature of these acts should exclude the repetition of the provisions of regulatory legal acts and provide for additional requirements for business and professional activities. The legislation applies content requirements to standards and rules and, in some cases, provides for mandatory approvals and conclusions of certain organizations. However, the regulatory legal regulation leaves questions about the procedure for approving and obtaining an opinion on standards and rules, the competence of the authorized body, and the development of business ethics standards. The analysis of the existing standards revealed the fact of poor-quality development of standards by self-regulating organizations and the unavailability of information about their approval. Thus, corporate acts of self-regulating organizations have a legislative basis and not only contain provisions on organizational issues, but also significantly determine the internal regulation of its activities. The elimination of existing inaccuracies in regulatory legal acts will contribute to the improvement of the effectiveness of regulation in the field of business and professional activities.

Published: June 2024

The main objective of fluid storage tanks construction is to construct safe and low-cost storage tanks which are resistant against earthquake. But in the computer design methods for the design of low cost and high performance storage tanks, little attention has been paid to development of quantities. In this study, first the underground tanks were compared to non-underground storage tanks and the results showed that underground tanks had better performance in terms of maximum displacement and stress against their wall. Afterwards, the impact of changes made in the underground tanks through the depth of underground tank, the type of soil around the tank, the distribution of dynamic pressure by different fluids, the impact of water depth on the tank frequency, and ratio of length to height on frequency of the tank, was investigated. The results of this study suggest that any increase in the tank depth leads to an increase of the tension and displacement and with softer soil around the tank more critical results will be achieved. In addition, the fluid dynamic pressure distribution is strongly linked to the specific weight of the fluid. With any rise in the water level of the tank or increase of length to height ratio, the frequency of the tank is reduced.

Study of Accountability of Policymakers and Curriculum Implementers for Curriculum Implementation in Ethiopian Primary Schools
Authors: Beyessa Feyera , Kenea Ambissa
Published: June 2024

This study aimed to explore the compact accountability relationship for curriculum implementation in rural public primary schools in the east Wollega zone administration, Ethiopia. An exploratory case study type and a multiple case study research design were employed. The purposeful sampling technique was used. The data were collected using semi-structured interviews and document reviews. The data were analyzed qualitatively. The findings of the study reveal that the compact accountability relationship between the policymakers and the curriculum implementers was loosely exercised and compromised by main determinants such as weak capacity, poor monitoring progress, and politicization of the policymakers’ roles and responsibilities. This study also affirms that a compact accountability relationship was seriously operational to collect easily achievable reports, which led policymakers to be unsuccessful in communicating their clear duties and responsibilities for the curriculum implementation to hold implementers accountable as stated in the government proclamation. Hence, it can be concluded that accountability stands for responsibilities outside the classroom by missing the actual curriculum implementation. The study recommends that the government should establish an autonomous and independent policymakers’ office that acts as a monitor and holds curriculum implementers accountable by visiting schools, pointing out mistakes, writing reports, and exercising accountability mechanisms.

Religious Violence and Insecurity in Nigeria
Authors: V. N. Effiom , F. A. Unimna , B. G. Ele
Published: June 2024

Ethnic and religious disputes present Nigeria with more internal concerns than external ones at the moment. Socioeconomic, political, and governance deficiencies are frequently cited in the research on religious violence in Nigeria as the primary drivers of this violence. Insecurity and religious violence in Nigeria are examined in this paper. Assassinations, ritual killings, armed robberies, kidnappings, tribalism, avarice, corruption, ethno-religious violence, banditry, and insurgency are just a few of the security concerns the nation currently faces. The technique relies solely on textual sources, which include books, journals, records, monographs, manuscripts, and magazines. The paper's major argument is that, when combined with other circumstances, religious violence has raised the sense of insecurity in the nation. As a result, there have been losses in human life and property, an increase in armed conflict, fear and instability across the nation, and the need for more security personnel. The study suggests, among other things, electronic surveillance of the nation's borders to prevent the smuggling of illegal weapons into the country, correct religious teaching, de-radicalization of religious violence, and more. Such actions are thought to aid in halting the nation's unsightly tide of insecurity. In addition to ensuring the peaceful coexistence of Christians, Muslims, Traditionalists, and adherents of other faiths, this would also contribute to Nigeria's restoration of peace, security, progress, and prosperity.
Technology gap ratio decomposition in smallholder solar saltworks in Indonesia using meta-frontier data envelopment analysis (MetaDEA)
Authors: Prihantini Campina Illa , Hanani Nuhfil , Asmara Rosihan , Syafrial Syafrial
Published: June 2024

The increasing population in Indonesia results in the rising demand for consumer goods, including salt. Meanwhile, salt production in Indonesia remains traditional, using direct methods by evaporating seawater in open ponds near the coast, producing a final product called “solar salt”. This process depends on sunlight, air, weather, and seasonal climate conditions. This research aims to analyze the technical, technological, and managerial disparities among traditional solar salt farming businesses operated by local communities across regions in Madura Island—the foremost solar salt-producing region in Indonesia. This study employs primary data collected through surveys conducted during the production season in 2023/2024 in three regencies in Madura: Pamekasan, Sampang, and Sumenep. The structured questionnaires captured the input and output data. Meta-frontier Data Envelopment Analysis (meta-DEA) was applied to assess the technical efficiency of conventional solar salt productions across the research regions. The efficiency analysis revealed that, with the current production methods, solar salt farmers achieved an efficiency rate of 46.98%, with an average technical efficiency of 80.83%. This result shows that the decision-making units (DMUs) can enhance their technical efficiency by 19.07%. Meanwhile, the technology gap ratio (TGR) analysis indicates that Sumenep Regency has the highest TGR value, nearing the threshold of 1, suggesting a relatively low technology gap in this regency. The meta-DEA decomposition indicates that the determinant of the average meta-technical inefficiency among solar salt farmers is the technological disparities, with average technological gap inefficiency (TGI) values surpassing managerial gap inefficiency (MGI) values. Conversely, Sumenep Regency has a larger MGI than TGI value, implying that solar salt farmers in Sumenep possess lower managerial decision-making skills than in other regions. The findings suggest the need to enhance the adoption of the latest production technology innovations to address technological gaps in the research locations.

Published: June 2024

This research aims to describe the institutional recognition of the rational use of common resources in a Mexican reserve from a management and implementation perspective. After its declaration as a reserve, new environmental management systems were established, and the local population had to incorporate new institutions and, with this, new permitted and prohibited actions. The methodological strategy consisted of a mixed study that included surveys in eight municipalities with a convenience sample of 400 people and key informant interviews. The results reveal that, although the initial configuration by decree was top-down, the information that all inhabitants needed to recognize the institutions responsible for the new policies was not disseminated. Therefore, after almost 24 years, the need for an integrated and participatory management that actively includes the local community and the various entities involved is still pending.

Authors: Leonte Daniela , Cheptanaru Olga , Uncuţa Diana
Published: June 2024

Introduction. Periodontal health plays an important role in the longevity of prosthodontic restorations. Proper treatment planning and prosthetic treatment are essential for the long-term outcome of prosthetic dental treatment. Various environmental and dietary factors can adversely affect the balance of the oral cavity, leading to inflammatory and destructive diseases of the teeth. To achieve a successful treatment outcome, prosthodontists and periodontists should collaborate, to enhance the longevity of the restoration and improve periodontal health, as well as improve the quality of life for dental patients. Purpose. The aim of this study is to review and present the current knowledge regarding the various technical and clinical aspects of different prosthetic biomaterials and highlight the interactions between periodontal health and prosthetic restorations. Materials and methods. In the study we selected a sample of 10 patients aged 30-60. We used cobalt-chromium ceramic prostheses fabricated by the conventional method, cobalt-chromium ceramic prostheses fabricated by a CAD/CAM technique and zirconium prostheses fabricated by a CAD/CAM technique. Fixation is achieved by cementation. As research methods we used detailed clinical examinations, including measurement of periodontal pocket depth by means of periodontal probes, also intraoral radiographs for bone level assessment. Results. It has been found that the average duration of use of fixed prosthetic constructions is 8.8 years, offering a perspective on the period of functionality of the prosthesis. The prevalence of complications and/or failures of fixed prostheses, which may include a number of problems such as: mismatch of shades, overcontact, marginal opening, caries, periodontal disease, gingival bleeding, overlaping edges, fractured porcelain, discomfort, pain, periapical lesion, occlusal wear, abutment fracture. Conclusion. Before starting prosthetic treatment, the condition of the periodontal tissues should be evaluated for their oral hygiene status, as well as the gingival and periodontal conditions. Zirconium-based restorations made from the CAD/CAM technology provide better results, in terms of marginal fit, inflammation reduction, maintenance, and the restoration of periodontal health and oral hygiene, as compared to constructions made by conventional method and from other alloys. Compared to subgingival margins, the supragingival margins offer better oral hygiene, which can be maintained and does not lead to secondary caries or periodontal disease.

Published: June 2024

Introduction: Temporomandibular disorders (TMD) are a global public health problem affecting between 5-12% of the population, determined that the age peak with the highest incidence is among young people (up to 35 years), and with the advancement in age it decreases. In recent decades, special attention has also been paid to investigating the manifestation of temporomandibular disorders among adolescents, attesting to an increasing trend in prevalence in this age group. In the specialized literature, the peculiarities of the clinical expression of these conditions and the association with the sex of patients are not fully elucidated, especially regarding the cardinal symptoms related to the pain syndrome associated with TMD. The purpose of the study: to determine the peculiarities of the manifestation of pain syndrome in young people (adolescents, young adults) with temporomandibular disorders. Material and methods: Between 2022-2023, 37 young patients with temporomandibular disorders (mixed clinical form – myogenous-arthrogenous TMD) – 19 adolescents (10 girls, 9 boys) and 18 young adults (14 women, 4 men), who were referred to the university clinical bases of the departments of therapeutic dentistry and pediatric OMF and pedodontics “Ion Lupan”. The diagnosis of temporomandibular disorder was predetermined by applying the diagnostic criteria from the DC/TMD protocol. The clinical instrumental investigations were based on the evaluation of the number of pain-positive stomatognathic sites during the clinical examination and the investigation of the pain sensitivity thresholds (PPT) at the level of the masseter muscles and TMJ by means of the Wagner FDIX algometer (USA). Results: In the analyzed sample, a different gender distribution was determined in the 2 age groups – in teenagers, the proportions being approximately equal between girls and boys, while in young adults (18-29 years) a predominance of the female sex, with statistical significance (Chi2 = 5.65, p = 0.0174). The average number of algic positive sites in adolescents was 13.72±3.1, and in young adults 10.34±1.21, in adolescents a tendency to more frequent painful masticatory muscles was observed, the number of affected sites decreasing with age. Also, the average sensitivity thresholds were lower in female adolescents and young adults compared to males, both at the level of masseter muscles (0.64±0.12 vs. 0.89±0.7) and TMJ (0.34±0.2 vs. 0.43± 0.4). Conclusion: In young people (adolescents, young adults), an expression of the pain syndrome associated with temporomandibular disorders is attested to be more extensive (especially larger number of affected muscle sites) as well as in intensity (lower sensitivity thresholds), in especially with tendencies of more pronounced manifestation in female persons.

Published: June 2024

One of the Indonesian provinces where the agricultural industry drives the economy is Punung, Pacitan, which has local conditions that are particularly suitable for producing citrus, giving this product the potential to continue to expand in popularity. Land evaluation tries to provide information on its potential for a particular purpose. This research was conducted to know land suitability classes, limiting factors, and improvement efforts that can be made. This research is exploratory descriptive with a variable approach through field survey and using a purposive random sampling method based on Land Mapping Units. Data analysis was carried out using the matching method between land characteristics and conditions for growing citrus, a statistical test by ANOVA (Analysis of Variance), and Duncan’s Multiple Range Test (DMRT) to find the factors that most determine land characteristics in Punung. The study results show that the actual land suitability class in Punung is marginally suitable. Improvements that can be made to increase the availability of nutrients in the soil in the form of available P2O5 with a low level of management is to apply P fertilization according to the needs of citrus. ANOVA results proved that the variety of soil types significantly influences some of the land characteristics.

Published: June 2024

Adobe construction is widespread in many rural areas around the world. It is characterized by being traditional and corresponds to the climatic characteristics of the regions in which it is located, as well as low energy consumption and compatibility with the principle of environmental conservation. In addition to the possibility of recycling. However, it has such disadvantages as fragility and wilting due to climatic factors. Modern research has, therefore, focused on increasing the hardness of this brick. This study aims to study the effect of using palm and lime fibers in adobe bricks. According to previous studies, it is one of the most important ways to improve the mechanical properties of adobe bricks. We are studying bricks from the Adrar region in the south of Algeria. Where we change the ratio of lime to 5%، 10%، 15%، 20%. We change the percentage of palm fibers from 0.1% to 0.5%. We determine the ideal water content and study the change in density and mechanical pressures inside a scientific laboratory using systematic experimental methods. The study focuses on determining the best ratio between palm and lime fibers, which gives us the highest hardness of the samples. Preliminary results indicate that adding palm fibers reduces the bulk density value by 0.34% to 8.53%, which makes the brick lighter. The value of mechanical stresses increases from 7.89% to 26%.The best ratio is 0.2% palm fibers to 15% lime, which is a positive ratio in terms of solidity. These results allow us to know the ideal proportions between palm fibers, lime, soil, and water so that we can take advantage of them in future studies.

Published: June 2024

Optimization of the control of doubly fed induction generators (DFIGs) is essential for many applications, such as renewable energy systems, industrial automation, and electric cars.  Unfortunately, the dynamic and non-linear character of DFIG frequently makes it difficult for conventional control techniques to adjust, which results in less-than-ideal performance. To overcome these obstacles, this paper presents an optimized fuzzy speed control of a doubly fed induction wind generator using a genetic algorithm, which has more advantages than its counterpart PI speed controller. In this study, the modeling of generator in the Park's frame was presented, as well as its indirect vector control applied to the stator flux. Then, to guarantee tracking of the ideal operating point in real-time and to produce the most electricity possible for varying wind speeds, we used a fuzzy PI speed controller. To improve the sizing operation of this controller, we opted for the genetic algorithm technique combined with one of the local search methods, which facilitated the search and reduced the effort compared to the trial-and-error sizing method. Furthermore, this made it possible for the wind system to track the optimal power point maximum with good performance. The simulation results of the suggested control displayed by MATLAB-Simulink illustrate the effectiveness and adaptability of the proposed control scheme across different operating conditions. The analysis of the results showed good performance for speed, small voltage and current ripple when using the fuzzy PI speed controller with genetic algorithm technique. offering promising prospects for practical implementation in variable speed wind turbine applications.

Current Situation and Challenges of Safety Management of Chemical Laboratories in Universities: Problems and Countermeasures
Authors: Quan Fengling
Published: June 2024

University chemistry laboratory is an important base for teaching experiment and scientific research, and its experimental activities and scientific research results play an irreplaceable role in cultivating students' practical ability and promoting the development of the subject. However, with the increase of the frequency of laboratory use and the improvement of experimental complexity, the safety management of chemical laboratories in colleges and universities has become increasingly prominent. Laboratory accidents can not only cause serious harm to people and the environment, but can also have a negative impact on a school's reputation and the quality of education. Through the field investigation and data analysis of chemical laboratories in many colleges and universities, it is found that although many colleges and universities have established a set of safety management system, there are still many deficiencies in practical operation, such as weak safety awareness, imperfect safety facilities, insufficient safety training and lack of emergency plans. These problems not only threaten the safe operation of the laboratory, but also restrict the smooth development of scientific research and teaching activities. In view of the challenges facing the safety management of chemical laboratories in colleges and universities, safety education and training should be strengthened to improve the awareness and attention of teachers and students to laboratory safety. Secondly, it is necessary to improve the safety facilities and ensure that the hardware equipment of the laboratory can meet the safety requirements. In addition, a sound safety management system and emergency plans should be established to respond quickly and effectively in emergency situations.

Authors: Shi Jilong
Published: June 2024

According to the ratings of delivery applications, the most common question raised by customers is poor food quality. Hence, the research paper on an energy harvesting system to help improve food delivery quality without consuming additional energy is being carried out. The detailed demonstration of a completed energy harvesting system shows that renewable energy can be collected from the commercial vehicle and converted into extra electrical power, which can be stored and used properly. This conceptual design is raised and tested by others, which is listed in the references, but the application after energy harvesting is not mentioned. Therefore, a meaningful idea to improve food delivery services is coming up due to food delivery becoming more and more common in daily life. Basically, the electricity is converted from the suspension’s kinematic energy, which can be achieved by wrapping coils around the spring and inserting a magnetic inside shock absorber to generate electrical power. The electricity is stored in a lithium-ion battery and used to charge the food container named food blazer.

Published: June 2024

The invasive sea lamprey has posed significant challenges to aquatic ecosystems, affecting biodiversity and the fishing industry. This paper endeavors to quantitatively assess the impacts of sea lamprey population, explicitly accounting for variation in sex ratio, on both prey population and others within ecosystem, thereby facilitating the formulation and implementation of more strategically focused management interventions. The paper achieved the aforementioned objectives by developing a differential equation-based sea lamprey-prey population dynamics model to quantify impacts on prey population, and employing the AHP-TOPSIS framework to quantify the broader ecological impacts. This comprehensive approach provides a holistic perspective on the sea lamprey's cumulative impact on the ecosystem.

Alzheimer's disease (AD) is the most common type of dementia among the elderly, which has become the focus of global public health and social attention. This study is proposed to explore the relationships between 4 factors (gender, age, years of education and socioeconomic status) with AD by the use of the Binary regression model and correlation regression. It was concluded that female have a dramatic positive impact on AD significantly (p<0.01, OR = 3.517), and the years of education will have a remarkable negative impact on the Groups (p=0.011, OR =0.784). However, the Age and socioeconomic status will not have an impact on the AD (p=0.748 and p=0.622). The early prevention is feasibility and importance to delay the onset of AD and to improve patients' quality of life. Accordingly, an effort should be made to improve the professional care and formulate relevant policies for elderly care services, especially for Women with low education.

Published: June 2024

With the change of people's lifestyle, the prevalence of chronic diseases continues to rise, and the health status is closely related to age, diet, physical activity, occupation and so on. In order to further analyze the relationship between common chronic diseases (such as hypertension and diabetes) and smoking, drinking, eating habits, living habits, work nature, exercise and other factors, as well as the degree of correlation, this paper conducted dimensionality reduction on two variables of living habits and eating habits, and entered the data after dimensionality reduction into pearson correlation coefficient test to analyze the correlation. The second dimension reduction is carried out again, and fewer indexes are obtained. According to the index after the second dimension reduction, the multiple regression analysis model is established to analyze the correlation. This study has reference value for residents to choose healthy daily life style.
