INNOVATION FOR EMPOWERMENT OF WAQF LAND RIGHT: COMPARATIVE ANALYSIS OF LEGAL ASPECTS OF WAQF LAND AND LAND WITH RIGHT OF MANAGEMENT IN INDONESIA
Authors: Djumeno Lutfi Djoko , Fauzi Fahrul
Published: February 2022

The existence of waqf institutions in Indonesia has the potential to be developed, considering that Indonesia is a country with the largest Muslim population in the world. One of the most common waqf objects is waqf land. Currently, waqf land in Indonesia is relatively not used productively. The current use of waqf land is mostly limited to mosques, tombs, and madrasas. This paper provides an innovation on the management of waqf land that has not been productive in the form of giving land rights on the waqf land. The research method used in writing this article is normative legal research. This study uses primary legal materials namely Law No. 41 of 2004, Law No. 11 of 2020, and Government Regulation No. 18 of 2021. This study found a point of similarity between the concept of waqf land and land with right of management. Indonesian Land Law recognizes various kinds of land rights, such as right of ownership, right of cultivation, right of building, and right of use.  This concept can provide benefits for developers, nazhir, and the Ummah. Developers get benefits in the form of freedom in land acquisition costs and can guarantee their land rights. Then, nazhir benefits in the form of land use fees and a recommendation fee from the developer. The profits received by nazhir can then be used for the welfare of the people according to the waqf pledge.
ON THE ISSUE OF SETTING THE LEVEL OF SEISMIC IMPACT ON HIGH-RISE BUILDINGS
Authors: Мозжухина Л.В.
Published: February 2022

Рассматривается вопрос задания расчетного уровня сейсмического воздействия на высотные здания. Для этого анализируются соот­ношения ущербов от землетрясения высотных (25-этажных) и низких (5-этажных) зданий. Для них построены функции плотности распределения ущерба от землетрясений различной силы и повторяемости. В качестве базового распределения ущерба при земле­трясении принято b-распределение. Для задания воздействия использовано обобщение принципа сбалансированного риска. При этом требуется совпадение не рисков (математического ожидания ущербов), а заданных вероятностей предельных состояний. Показано, что при высоких требованиях к допустимому риску высотные здания должны проектироваться на более высокую нагрузку, чем обыч­ные. Приведены оценки повышающего коэффициента. Проведено сопоставление полученных оценок с нормативными данными и пред­ложениями других авторов.
Revitalization of Fangyan Through Social Media Promotion in China
Authors: Guo Haiyan , Ni Zhijuan , Wang Zhiying , Zhang Yu , Li Jia
Published: February 2022

Compared to Putonghua, Fangyan is often indexed with social stereotypes such as lack of education, uncivilization and low-class. However, such negative indexicality of speaking Fangyan has been challenged by the emerging circulation of diverse social media online. Adopting the concept of language as commodity in late capitalism (Heller, 2010), this study examines how Fangyan is constructed and promoted as an index of authenticity and authority, a source of knowledge dissemination and commodified capital. The study argues that the revitalization of Fangyan from below cannot be simply reduced to the celebratory discourse of cultural diversity but should be understood in a wider discourse of language as profit which is subordinated to the power and social relations. The study can shed lights on the promotion of linguistic diversity and intercultural communication.

Anyhow, at the end road of Karanglo Intersection causes traffic jam and long vehicle queue. Related with that problem, so it is necessary to analyze the intersection performance, alternative improvement, and vehicle operating cost at the Karanglo intersection. The data used in this analysis are primary and secondary data. Primary data are obtained from road geometric measurements and phase and signal cycle measurements, while secondary data are obtained from the Central Statistics Agency (BPS) of Malang Regency and forecasting LHR data and side barriers. For the data processing, it uses Indonesian Highway Capacity Manual (MKJI) method 1997. Vehicle operating cost uses a handbook from Ministry of Public Works Directorate General of Highways 2005. Based on the analysis’ result, the performance of the existing intersection condition obtained delay (D) = 220.12 and the intersection service level (LOS) = E. From the analysis’ result, it is needed an alternative of intersection refinement by designing the signal phase, so that the delay (D) = 21.99 and the intersection services level (LOS) = C. The Vehicle operating cost before there was underpass for light vehicle was Rp 6.143/km. The vehicle operating cost after the underpass for light vehicle was Rp. 4.979/km.

On West Bandulan Junction Street - Brigjend Katamso Street, Malang City often experiences inundation during the rainy season. The occurrence of flooding is caused by the capacity of the drainage channel which is not sufficient to accommodate the discharge of runoff, improper drainage planning garbage in the drainage channel, the amount of waste from households and industry and the large number of closed drainage channels because it is made for parking and community home yards . From this condition, the drainage re-design is carried out. This plan is made to re-design the dimensions of the drainage channels and calculate the WWTP (Wastewater Treatment Plant) requirements, as well as calculate the RAB. The results of the calculation of the planned channel dimensions are trapezoidal and square with the largest dimensions of the trapezoid having a width of 1.19 m, a bottom width of 0.8 m and a height of 1.09 m. while the largest dimension of a square has a width of 1.4 m and a height of 1.4 m. The results of the calculation of the need for WWTP require 4 WWTP with different capacities, namely IPAL 1 with a capacity of 4 m3, IPAL 2 with a capacity of 12 m3, IPAL 3 with a capacity of 3 m3, IPAL 2 with a capacity of 2 m3. Based on the results of the calculation of drainage redesign, it can be concluded that the cost of redesign the drainage and WWTP is Rp. 6,473,335,422.

Одной из важнейших экологических проблем в настоящее время является загрязнение окружающей среды полимерными отходами. Эта проблема играет важную роль не только в жизни населения Республики Казахстан, но и во всей экологической системе страны. Количество полимер- ных отходов растет с каждым годом. Отходы полимеров засоряют наши города и способствуют появлению множественных проблем со здоровьем у людей и животных. Большее количество поли- мерных отходов отправляются на специальные полигоны и свалки. На данный момент наблюдается значительный прирост количества полигонов и свалок. Эта ситуация сложилась из-за отсутствия пунктов сортировки во многих регионах Республики Казахстан. Решение всех указанных проблем зави- сит не только от правительства, но и от нас самих. Если мы будем использовать меньше полимерных изделий в нашей повседневной жизни, перерабатывать их, то мы сделаем окружающую среду чище. В наши дни существуют и модернизируются различные способы по переработке и утилизации поли- мерных отходов, которые имеют свои преимущества и недостатки. Проблема утилизации полимер- ных отходов требует новые способы переработки и повторное использование полимеров в замкнутой системе так, чтобы они никогда не становились отходами. В статье представлен обзор методов переработки полимерных отходов, используемых на предприя- тиях Республики Казахстан, рассмотрены их преимущества и недостатки, этапы переработки поли- мерных отходов, требования для утилизации пластика, изделия из пластика. Рассмотрены и предло- жены к применению некоторые дополнительные устройства для вторичной переработки полимерных отходов.

Authors: Kersin Burak
Published: February 2022

OBJECTIVE: This study aimed to investigate the effect of hydrogen peroxide, on the extent of intraoperative bleeding and operation times in pediatric patients undergoing adenoidectomy. METHODS: Data of 86 adenoidectomy patients (47 males, 39 females; mean age 5.2±1.9 years; range 3 to 11 years) collected from patient files were retrospectively evaluated. The patients’ age, sex, and adenoid tissue size, as well as anesthetic technique, operation time, amount of bleeding during the operation, were reviewed. Among the patients, 45 were administered hydrogen peroxide for hemostasis (study group) and 41 patients were not administered hydrogen peroxide during operation (control group). RESULTS: No statistically significant difference was found between groups in terms of age, sex and, adenoid tissue size (p>0.05). The operation times of the study group were significantly lower than those of the control group (p=0.001; p<0.01). There was also a statistically significant difference between groups in terms of bleeding amount (p=0.001; p<0.01). Bleeding amount was significantly lower in the study group than in the control group. CONCLUSION: In this study, we determined that administration of hydrogen peroxide with nasopharyngeal packing significantly decreases operation time and intraoperative bleeding in adenoidectomy patients.

Authors: Bal Kemal Koray
Published: February 2022

OBJECTIVE: This study aimed to assess the preoperative hematologic factors for predicting post-tonsillectomy hemorrhage (PTH). METHODS: In the retrospective study, the records of 44 patients (21 males, 23 females; mean age 30.5±9.4 years; range, 18 to 55 years) who underwent tonsillectomy for chronic or recurrent tonsillar infections were reviewed. Age, sex, coagulation profile [international normalized ratio (INR), activated partial thromboplastin time (aPTT)], complete blood cell count [hematocrit (HTC), neutrophil (NEU) count, lymphocyte (LYMP) count, platelet (PLT) count, mean platelet volume (MPV), red cell distribution width (RDW)] such values have been recorded. Patients were divided into two groups according to the presence of PTH. Group A (8 males, 13 females; mean age 30.5±11.1 years) included patients without PTH and Group B (13 males, 10 females; mean age 30.5±7.8 years) was comprised of patients with PTH. RESULTS: In the evaluation of the coagulation profile, aPTT values were 24.5±1.9 sec in Group A and 26.4±17 sec in Group B (p= 0.017). Median value of INR was similar between the groups (p=0.60). No difference was detected between the groups regarding the following parameters of the complete blood count: HTC (p=0.49), NEU (p=0.17), LYMP (p=0.45), PLT (p=0.71), MPV (p=0.27), and RDW (p=0.29). CONCLUSION: It is important to perform relevant blood tests should in the preoperative period, in addition to INR and aPTT tests. New studies are needed to determine the relationship of MPV and RDW with PTH.

Different (n=21) commercial carbonated beverages, available in Bangladesh, were analysed by HPLC coupled with a photodiode array detector (UV-PDA). The main objective of this study was to quantify the amount of different artificial sweeteners, stimulant and preservatives and to validate the two methods used in this purpose. The two methods are simultaneous determination of sodium benzoate, caffeine, and saccharin using the sodium acetate buffer with pH 3.0 at 254 nm and simultaneous determination of artificial sweeteners acesulfame-K and aspartame using the potassium phosphate monobasic buffer. Correlation coefficient (r2) obtained were 0.9977, 0.9976, 0.9975, 0.9993 and 0.9956 in the range of 1-100 µ/L, recoveries were 95.88-97.10, 96.53-97.20, 94.53-96.05, 91.15-93.31 and 92.88-94.13%, LODs were 30.06, 15.46, 31.61, 0.33 and 0.83 mg/L, and LOQs were 100.18, 51.54,105.37, 1.11 and 2.77 mg/L for saccharin, caffeine, sodium benzoate, acesulfame-K and aspartame, respectively. The present analysis shows that amount of saccharin, caffeine, sodium benzoate, acesulfame-K and aspartame in the range of ND-377.60, ND-462.36, ND-217.60, ND-48.09 and ND- 295.20 mg/L, respectively. The total carbohydrate found as 102.81-147.16 g/L using the UV-visible spectrophotometric method which implies that sample containing more amount of carbohydrate has less artificial sweeteners value.

Meniran (Phyllanthus niruri L.) is a wild plant in the Euphorbiaceae family which grows in tropical climates. The plant is known to possess antioxidant activity and is rich in phenolic compounds. Since plants with high phenolic content and high antioxidant activity are known to exhibit high tyrosinase inhibitory activity, the purpose of this study is to determine the inhibitory activity of the tyrosinase enzyme by the methanol extract of meniran (P. niruri L.) and to isolate secondary metabolites from the extract and fractions which exhibit inhibitory activity against tyrosinase. The in vitro tyrosinase inhibitory activity assay was conducted using the 96-well microplate method with kojic acid as the positive control, while the separation and purification of compounds were carried out using chromatography techniques. The methanol extract and n-hexane fraction showed tyrosinase inhibitory activity with IC50 of 11.05±0.16 and 2.57±0.08 mg/ml, respectively. Three bioactive compounds were succesfully isolated from the n-hexane fraction. Based on the UV and NMR spectra, compounds 1, 2, and 3 were identified as phyllanthin, phyltetralin, and hypophyllanthin, respectively. Furthermore, phyllanthin (1) was shown to demonstrate inhibitory activity against tyrosinase with IC50 of 0.6322 mM. In conclusion, both meniran extract and phyllanthin (1) were found to exhibit inhibitory acitivity against the tyrosinase enzyme. In the future they can be candidates for the treatment against hyperpigmentation and also as an active ingredient in skincare formulations.

Indole-3-acetic acid (IAA), a phytohormone, is a crucial modulator of plant growth and development. As increased levels of endogenous IAA is responsible for inhibitory effects on plants, knowing its concentration would be helpful for controlling exogenous IAA input. An optimum endogenous IAA level is required for proper growth and development of plant with good health status. Hence, in this study, we have detected and measured IAA present in tomato root, shoot, leaves and fruits at two different ages (25 days and 50 days) by Reversed-Phase High Performance Liquid Chromatography (RP-HPLC), a suitable chromatographic method for separating molecules based on hydrophobicity. We observed that the endogenous level of IAA was significantly higher in roots, shoots, leaves and fruits at 50-days old plant compared to 25-days old mature plant (p-value <0.01). These results suggested that the IAA level may increase with the increase of the age of tomato plants. The tomato plants showed good vigor with IAA range 0.3-3.0 µg/g.F.W (25 days) and 3.4-7.5 µg/g.F.W (50 days) of age, respectively, implying that IAA might be used as a possible plant health indicator. Further study is needed to manipulate the IAA concentration for adequate plant growth and development.

Humanity is in the midst of the coronavirus disease 2019 (COVID-19) pandemic, and vaccines—including mRNA vaccines—have been developed at an unprecedented speed. It is necessary to develop guidelines for vaccination for people undergoing treatment with assisted reproductive technology (ART) and for pregnancy-related situations based on the extant laboratory and clinical data. COVID-19 vaccines do not appear to adversely affect gametes, embryos, or implantation; therefore, active vaccination is recommended for women or men who are preparing for ART. The use of intravenous immunoglobulin G (IVIG) for the treatment of immune-related infertility is unlikely to impact the effectiveness of the vaccines, so COVID-19 vaccines can be administered around ART cycles in which IVIG is scheduled. Pregnant women have been proven to be at risk of severe maternal and neonatal complications from COVID-19. It does not appear that COVID-19 vaccines harm pregnant women or fetuses; instead, they have been observed to deliver antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to the fetus. Accordingly, it is recommended that pregnant women receive COVID-19 vaccination. There is no rationale for adverse effects, or clinical cases of adverse reactions, in mothers or neonates after COVID-19 vaccination in lactating women. Instead, antibodies to SARS-CoV-2 can be delivered through breast milk. Therefore, breastfeeding mothers should consider vaccination. In summary, active administration of COVID-19 vaccines will help ensure the safe implementation of ART, pregnancy, and breastfeeding.

Published: February 2022

The year 2021 marked the beginning of the United Nations (UN) Decade of Ocean Science for Sustainable Development. The world now has fewer than 10 years to achieve the UN Sustainable Development Goals. In this article, we reflect on some of the challenges and opportunities this presents for Early Career Ocean Professionals (ECOPs) who will be instrumental in designing, delivering, and using ocean knowledge toward a more sustainable and equitable future. How can Ocean Decade programs and partnerships equip ECOPs with the necessary tools, skills, and opportunities to engage meaningfully with policy processes and to develop practical solutions for societal benefit? We propose some key questions for discussion among ocean scientists, ocean-dependent communities, and policymakers.
Factors Fostering Shadow Economy Performance in Poland and Lithuania during 2000-2019
Authors: Buszko Andrzej
Published: February 2022

This study relies on a calculable and essential analysis of a statistically oriented regression model. Ninety-five variables taken into consideration in this research were grouped into four categories. The first category covers the general macroeconomic situation, the second is devoted to crime, the third is formed by characteristics of income and living conditions, and the fourth one applies to the taxation system. The Multiple Indicators Multiple Causes (MIMIC) model was employed to measure the level of shadow economy in Poland and in Lithuania during 2000-2019. The MIMIC model depends on Structural Equation Models. The MIMIC approach allows one to assess shadow economy as a latent variable. The observed factors are government employment/labor force, tax burden, subsides/GDP, social benefits paid by government/GDP, self-employment/GDP, and unemployment rate.  The Pearson correlation index was used to size up the correlation between independent variables, and Kolmogorov–Smirnov (KS) test for normality of residuals was applied. In both countries, factors affecting the shadow economy performance show great similarity. The shadow economy development in Poland and in Lithuania is fostered by many different factors, related to, but not limited to, the general macroeconomic situation. In fact, the economic situation is associated with the standard of living, income as well as the crime rate. Important factors are associated with the taxation system. The results demonstrate that the regression model can be used to predict the shadow economy development and performance in Poland and in Lithuania. Such information facilitates taking adequate steps in order to minimize the shadow economy level in both countries. Such implications are very useful for decision makers in shaping the legal and economic progress in both countries.
Economic Policy Uncertainty and Manufacturing Value-added Exports
Authors: Zhao Tingting
Published: February 2022

This study explores the effects of increased economic policy uncertainty (EPU) in both importing and exporting countries on manufacturing value-added exports. The results show that increased EPU of both importing and exporting countries would result in decreases in manufacturing value-added trade flows, and the negative effect of exporters' EPU is larger than that of importers' EPU. Our results also provide evidence on the influence channels: increased EPU of exporting countries affects manufacturing value-added trade flows primarily through the cost to export, while increased EPU of importing countries primarily through market demand. This conclusion is robust to a series of robustness checks.

The Influence of a Diamagnetic Copper Induced Field on Ion Flow and the Bernoulli Effect in Biological Systems
Authors: C. Purnell Marcy
Published: February 2022

The Bernoulli Effect describes the principle of conservation of energy that optimizes pressure and motion in fluid flow and may be applied to fluid dynamics in vascular arterial and cellular membrane flow. One mechanism that is known to influence fluid flow that has not been included in the Bernoulli Effect equations is viscosity or resistance to flow. To date the liquid phase of matter with regards to the relationship between viscosity, pressure and flow is the least well understood of all phases. Recent cellular studies suggest that a diamagnetic copper influenced dielectrophoretic electromagnetic field may induce a Bernoulli Effect within biological systems. The data presented here suggests that an increased viscosity via this copper influenced dielectrophoretic electromagnetic field may significantly contribute to this Bernoulli Effect or conservation of energy while positively impacting cellular health and function via both kinetic and potential bio-energy influences in biological systems.

Published: February 2022

When lignocellulosic biomass is used as a substrate in anaerobic digestion processes, a pretreatment stage is always required to break the hard structure of the material and facilitate the attack of microorganisms and, with it, their degradation. Numerous methods have been developed to pretreat lignocellulosic biomass. Four of them: torrefaction, cavitation, pelletizing and extrusion have been comparatively evaluated in this article as ways to increase methane production through anaerobic digestion of two raw materials with different lignin content: barley straw and vine shoot. In addition, it was examined how these pretreatments and the nature of the feedstock influence the volatile fatty acid profiles that are generated during the digestion process. The cavitation of biomass milled at 0.25 mm was revealed as the most efficient pretreatment among those tested, increasing by 360% and 240%, respectively, the methane production for vine shoots and barley straw.

Having a device that does not need an electric, pneumatic, or hydraulic actuator neither a digital control to work for a specific task is the goal for any application. This research shows that it is feasible to develop a device with the above characteristics to apply creep tests for overhead conductors.
There are two primary creep test methods for Aluminum Conductors in Overhead Lines (ACSR (aluminum conductor, Steel reinforced)) to obtain the tensile creep characteristics. They are the European standard IEC 61395, "Creep test Procedures for stranded conductors" and "Method for Determining the Long Time Tensile Creep of Aluminum Conductor in Overhead Line," prepared by the Electrical Committee of The Aluminum Association.
Since both methods don't specify a convenient type of mechanism or specimen position to carry out the creep test and accomplish the tensile load accuracy requirement, this research aims to design a self-tensile lever controllable to an accuracy of plus and minus 1% according to IEC 61395.
This work's analysis focuses on the lever geometry parameters type I actuated by deadweights to meet the tensile load accuracy for specimen lengths of 2.5m and 12.5m.
Calculations of accuracy development of lever geometry for both selected conductor lengths apply by analytical and numerical methods and, finally, laboratory tests.

RESIDUAL PERFORMANCE ANALYSIS OF BRIDGE STRUCTURE CONSIDERING HEAVY LOAD EFFECT
Authors: Gao Ruyu , Xin Qin , Hu Xiuquan , Liang Chunyu
Published: February 2022

The structural performance of bridges eventually decreases, and risk in bridge operations increase, as well as the equivalent effect of vehicle loads, particularly heavy traffic. To further clarify the relationship between the residual performance of the bridge under heavy traffic and the fatigue damage, a batch of prestressed concrete fatigue test beams was designed. The equivalent fatigue load, considering the heavy load effect, was determined through investigation and statistics of actual traffic load data. The fatigue failure morphology and crack development of the test beam under the equivalent fatigue load were analyzed based on the fatigue damage principle. The constant amplitude fatigue test method was used to analyze the development law of concrete residual strain, non-prestressed tendon residual strain, and prestressed tendon residual strain. Based on the damage model theory, the damage equation between the damage variable D and the cumulative residual plastic strain ?p considering the effects of heavy traffic was found. In addition, through the test data, the fatigue damage evolution curve based on the development of residual strain was obtained. Research results show that the fatigue test failure is a bending failure of the non-prestressed tendon fatigue fracture. The fatigue life of the beam reduced drastically when the heavy load effect is considered. From the perspective of residual performance, the residual strain of concrete is a good indicator for calculating the fatigue damage index of beams. The research results provide an early warning of fatigue failure and performance evaluation.

Authors: Pratiwi Hardiyanti , Hasanah Nor Izzatil
Published: February 2022

Children use digital devices at an early age when the COVID-19 pandemic is increasing. Media mediation and digital discipline are needed so that increased access is accompanied by anticipation of negative content and strengthening the impression of positive content. This qualitative descriptive study aims to reveal the form of digital discipline and media mediation that parents apply to the use of digital devices by early childhood when implementing the work and study from home policy. The results showed that there were 3 types of disciplinary patterns applied by the participants in this study, namely: reducing the intensity and duration of access to digital devices, mitigating content, and combining the two. The discipline pattern is carried out with several strategies, namely: shifting activities, duration or situation restrictions, inhibition of access, and habituation. Meanwhile, the most frequently used media mediation by participants is the type of restrictive mediation. In addition, there are also those that combine various types of mediation, namely restrictive-co-viewing, technical-active, as well as restrictive-active.
Manusia dan lingkungan alam: Analisis faktor konfirmatori terhadap Nature Relatedness Scale Bahasa Indonesia
Authors: Adiwena Bartolomeus Yofana , Djuwita Ratna
Published: February 2022

The relationship or closeness between humans and the natural environment is a psychological construct that can be used to overcome environmental problems nowadays. Nature Relatedness Scale (NRS) is a questionnaire used to measure the relationship between humans and the natural environment, which is proven to be related to pro-environment behavior. However, there are no studies that have adapted and analyzed the structure of NRS in Indonesia, so that it can be used for studies on environmental psychology in Indonesia. This study aims to test the construct validity and reliability of NRS Bahasa Indonesia using confirmatory factor analysis (CFA) with a sample of Indonesian people (N= 174). The result shows that NRS Bahasa Indonesia has the same factor structure as the original NRS, namely: NR Self, NR Perspective, and NR Experience and can be used in research with a population of Indonesian people. NR Self and NR Experience have good construct reliability and validity, while NR Perspective has moderate construct reliability and validity. The potential of the NRS to investigate pro-environmental concerns and behavior, as well as suggestions for further research are discussed.
