Authors: Afnani Fawait , Yanti Jamilah Hamidi , Pratiwi Wiwit Sri Werdi
Published: December 2023

Bell pepper can be an antioxidant and has many health benefits because of the high content of vitamin C. Vitamin C contents in yellow and orange bell peppers were extracted using different protic polar solvents and analyzed using the UV-Vis Spectrophotometry method. In this research, the bell peppers were extracted using the maceration technique for two days in 90% concentration of solvents (methanol and ethanol, respectively). Subsequently, the maximum wavelength was determined, and then 100 ppm ascorbic acid was used as a standard solution to analyze vitamin C content. Linearity based on a calibration curve is used to obtain the correlation coefficient of concentration between the standard solution and vitamin C levels in the sample. The result of UV-Vis spectroscopy analysis of this sample shows 373.5 nm of λmax. The linearity is shown in the equation y = 0.0006 x + 0.019. The vitamin C content in all samples had significant differences based on randomized complete block design (RCBD) test result with α = 0.05. The vitamin C level in the yellow pepper sample with an ethanol solvent (340 mg/100 g) was higher than that of the orange pepper sample with ethanol (251 mg/100 g). Meanwhile, the vitamin C content in the sample of yellow peppers with methanol solvent (562.5 mg/100 g) was smaller than that of orange peppers with methanol solvent (757.5 mg/100 g). These contents indicated a different result in the level sources of vitamin C, even if the maceration process used a solvent with a higher dielectric constant.

Published: December 2023

Malaria is a serious caused by protozoan parasites such as Plasmodium groups and has fatal consequences for human health. The increase in the resistance of the Plasmodium parasites toward existing antimalarial drugs prompts the exploration of novel compounds. In this study, quantitative structure-activity relationship (QSAR) analysis using the semi-empirical AM1 method was conducted to identify the optimal model that relates physicochemical properties and biological activity of chalcone derivatives.  In addition, ADMET prediction and molecular docking were also carried out. Multilinear regression calculations for statistical parameters of QSAR models revealed that Model 4, with 11 independent variables, provided the best predictions and exhibited a robust correlation with antimalarial activity represented by inhibitory concentration (IC50). ADMET predictions indicated favorable absorption, distribution, metabolism, excretion, and toxicity properties, particularly for B2D, showing promising antimalarial attributes. Molecular docking studies targeting 5 mutated PfDHODH proteins revealed B2D’s potential to reach therapeutic targets efficiently. It has low docking scores for mutations I (-10.5 kcal/mol), II (-8.6 kcal/mol), and V (-10.5 kcal/mol) with RMSD < 2Å, in carrying out its role for antimalarial activity. This research successfully identifies B2D as an efficient inhibitor of PfDHODH receptors. Thus, it is a highly promising novel antimalarial drug.

Published: December 2023

Masalah psikologis sering diabaikan di masa pensiun dengan fokus pada aspek fisik dan keuangan yang lebih terlihat dan dipahami. Padahal, kebahagiaan adalah tujuan utama manusia dan mencerminkan kesehatan mental. Konsep flourishing sering digunakan untuk menggambarkan kesejahteraan mental yang tinggi. Meskipun ada perdebatan mengenai perspektif hedonia dan eudaimonia, penelitian ini mengkaji apakah subjective dan psychological well-being dapat memprediksi flourishing pada pensiunan. Studi melibatkan 72 anggota Ikatan Pensiunan Universitas Brawijaya yang telah pensiun selama 3-12 tahun. Data dikumpulkan menggunakan PERMA-Profiler, SWLS, SPANE, dan PWBS. Hasil analisis menunjukkan bahwa flourishing pada pensiunan dipengaruhi oleh subjective dan psychological well-being secara simultan (R=0,465; R2=0,216; p=0,000) dengan kontribusi sebesar 19,3%. Secara parsial, flourishing lebih dipengaruhi oleh PWB (β=0,283; p=0,000), tetapi tidak dengan SWB (β=0,013; p=0,953). Oleh karena itu, PWB adalah prediktor utama flourishing pada anggota Ikatan Pensiunan Universitas Brawijaya.

Published: December 2023

This research is based on refractory angina pectoris, which remains a problem despite advances in coronary heart disease treatment. Stem cell therapy is still in preclinical research stages to address refractory angina. Endothelial progenitor cells (EPCs) aid in improving endothelium and the growth of new blood vessels. Heart medication has shown to enhance both the quantity and function of EPCs in patients at cardiovascular risk or with heart disease. Previous studies reported that ACE inhibitors (ACEI) have a positive effect on EPCs. Thus, this study analyzes the impact of three different ACE inhibitors on EPC migration in laboratory conditions. Its aim is to ascertain the increase in EPC migration in stable coronary heart disease patients after ACEI administration. The research methodology involves an experimental design with a control group and post-treatment assessment only. Mononuclear cells are isolated from stable coronary heart disease patients' peripheral blood and incubated for 3 days. The EPCs are then divided into captopril, ramipril, lisinopril, and a control group, observed for 48 hours. EPC migration is assessed by counting the cells moving from the upper chamber to the membrane facing the lower chamber using a transwell migration assay after 20 hours, observed with a light microscope and Giemsa staining. Data analysis via ANOVA statistical tests indicates increased EPC migration in the captopril, ramipril, and lisinopril groups compared to the control. Captopril shows the highest effect among the groups, while no significant difference is observed between captopril and lisinopril, as well as between ramipril and lisinopril.

Authors: Hibono Paulus Ronald
Published: December 2023

The use of bone grafts in Indonesia continues to increase each year. Although Autograft is considered the gold standard in bone grafting, its use is often confronted with various challenges, similar to allograft. To address this issue, Bovine Demineralized Bone Matrix (DBM) can be considered as a substitute for bone grafts with the advantages of unlimited availability and more affordable costs. Currently, the Tissue Bank of Dr. Soetomo Hospital is developing bovine DBM, although there is no research yet on its potential toxicity.This study aims to evaluate whether bovine DBM has cytotoxic effects on human mesenchymal stem cells. In this experimental study, a total of 48 samples were involved, including a control group and two treatment groups (50% and 25%), each consisting of 16 samples. Mesenchymal stem cells were cultured and then treated with the addition of 50% and 25% DBM. Subsequently, cell viability was measured using the MTT Assay method.The collected data were processed by conducting normality and homogeneity tests and then analyzed using comparative tests with an independent t-test. The criteria for declaring cell toxicity were set at a viability of not less than 60% compared to the control group.The results of the MTT assay measurements showed that the mean Optical Density (OD) in the control group was 0.656 ± 0.021 (range 0.620-0.696), while in the treatment groups, it was 0.565 ± 0.022 (range 0.529-0.614) and 0.520 ± 0.022 (range 0.461-0.552), respectively. Statistically, the differences in OD between the control group and both treatment groups (50% and 25%) were significant (p<0.05). The average cell viability in both treatment groups was found to be more than 60%, indicating that Bovine Demineralized Bone Matrix is not toxic to human mesenchymal stem cells.

Authors: Sinar Aju Wulandari  , Putri Kirana
Published: December 2023

The high modus operandi and increasing technological sophistication have implicate the transnational movement of illicit drug trafficking. The phenomenon of increased narcotics crime cases poses a threat to countries, including those in the ASEAN region. This type of crime poses a threat to the production and trade of illegal drugs. ASEAN, as a regional organization in Southeast Asia, is still facing several challenges, particularly the commitment of its member countries to combating illicit drug trafficking. Aside from funding issues, geographical location, cultural challenges, and social customs are all factors influencing the speed with which narcotics are handled. Several programs were initiated by each country in the ASEAN region with the primary goal of collaborating to reduce narcotics distribution and abuse. This article aims to analyze the sustainability of the ASEAN 2015 Drug-Free Program and the role of UNODC in the ASEAN region. The normative legal research method was used in this article, with primary and secondary legal sources. The article concludes that the program for dealing with narcotics crime begins with the ASEAN drug-free declaration, which harmonizes member countries' perspectives through their representatives to eliminate the cultivation, consumption, and trade of narcotics across national borders. As an international organization, UNODC (United Nations Office on Crime and Drugs) exists to facilitate cooperation and coordination through programs initiated with special narcotics agencies from each member country. Coordination between the two organizations is critical for the successful implementation of the program that has been initiated.

Authors: Achmad Andyna Susiawati , Indradewi Astrid Athina
Published: December 2023

In order to implement the idea of fair business competition, this article will analyze the function and legal obligations of online marketplaces in limiting commercial actors as 'official stores'. Normative juridical law research with statutory and conceptual techniques was used to create this study. According to the results, the distribution of commodities from producers to consumers has been altered by digital disruption. Currently, a number of online marketplace platforms offer 'official store' services to a small group of business players so they can expand their enterprises exclusively. Applying 'official stores' terms and conditions to business actors is prohibited by both Law No. 5 of 1999, which prohibits unfair business competition, and Government Regulation 29 of 2021, which relates to the implementation of the trade sector. Distributors and agents of associated producers will face unfair economic rivalry as a result of producers entering the online market as 'official stores'. Producers are prohibited from selling their products in retail settings, whether offline or online, in accordance with the relevant legislation. The findings of this study should benefit the parties involved in the online marketplace by fostering fair commercial competitiveness.

The community empowerment activity begins with a careful preparation process, followed by collaborative efforts with partners, the assembly of biogas reactors, and socialization initiatives, and concludes with an evaluation phase. The findings derived from this project indicate that the Habaring Hurung Village community has demonstrated proficiency in constructing biogas reactors. Moreover, there has been an obvious improvement in the community's understanding of liquid waste utilization and environmental management.
Gendered Parenting: Maternal Son Preference and Depressive Symptoms in Chinese Early Adolescents
Authors: Zhao Fengqing , Wang Yinge , Li Yudan , Li Sen , Wang Zhongjie , Hou Jie
Published: December 2023

This study focuses on the nuanced phenomenon of gendered parenting by exploring “how” and “when” maternal son preference associates with depressive symptoms among Chinese early adolescents. Focusing on 1,093 junior high school students from a relatively affluent city in western China, the research examined the mediating roles of mother-child attachment and father-child attachment, as well as the moderating role of school connectedness in the relationship between maternal son preference and depressive symptoms. The results revealed a noteworthy positive correlation between maternal son preference and depressive symptoms among female adolescents, with no significant association observed in males. In addition, mother-child attachment and father-child attachment mediated the relationship between maternal son preference and depressive symptoms, which supported the “spillover effect” and “crossover effect”. Moreover, moderation effect analysis indicated that higher level of school connectedness can buffer the effect of maternal son preference on girls’ depressive symptoms, while lower level of school connectedness can enhance the effect of maternal son preference on girls’ depressive symptoms. These insights help to enhance people's understanding of gendered parenting, emphasizing the enduring necessity of addressing son preference within the broader context of promoting gender equality.

Authors: Hasan Md. Zakir , Toda Yuji
Published: December 2023

This study investigated riverbank protection strategies along the dynamic Jamuna River in Bangladesh, a braided river prone to erosion and sedimentation. It reviews past countermeasures and emphasizes the effectiveness of groyne-type structures in redirecting flow and preventing erosion. Notably, the left bank exhibited greater stability than the right bank, emphasizing the need for effective groyne installations. A systematic methodology utilizing numerical modeling using International River Interface Cooperation (iRIC Nays2DH) ensured accuracy in assessing morphological impacts. This study presents novel countermeasures incorporating groyne installations in Zone 1 (from Singrabari to Meghai) and Zone 2 (from Pachthakuri to Subhagacga), accompanied by simulations for various flood conditions. Zone 2, identified as highly erosion-vulnerable, showed the greatest susceptibility. Simulations (Cases_0 1, 2, and 3) revealed groynes in Zone 1 alone ineffective, while Zone 2 installations successfully diverted oblique flow, reducing erosion risk. Although Case_3's combined approach was effective, it was uneconomical for Zone 1. Case_2, focusing on Zone 2 groynes, emerged as the optimal solution, redirecting flow and shaping sandbars to mitigate Jamuna River's riverbank erosion. It provides a practical and economical solution. Further research is recommended for groyne length and spacing variations. This study enhances Jamuna River protection, emphasizing groyne-type structures' importance and promoting a holistic understanding of morphological dynamics for future river management and effective countermeasures.
Elliptical Space as the Possible Origin of Matter
Authors: Yershov Vladimir N.
Published: December 2023

I argue that the main feature of elliptical space – the topological identification of its antipodal points – might be behind some observational facts on both cosmological and microscopic scales. I use calculated distance moduli of type-Ia supernovae, which are commonly regarded as “standard candles” for distance measure in cosmology. These are compared with the observational data collected in a catalogue called “Pantheon+”. On the microscopic scale I show that a physical elliptical space, in which the mathematical connectedness between antipodal points is replaced with physical connections via the Einstein-Rosen bridges (also called “wormholes”), gives rise to sub-particle structures similar to J.A. Wheeler’s geons. The interactions between these structures leading to their equilibrium configurations can explain the experimentally observed pattern of properties of elementary particles forming the standard model of particle physics. The answer to the question why we have this particular set of fundamental particles might lie in the fundamental properties of elliptical space.

Corrosion is a major concern in the marine industry, compromising the safety and integrity of ships. This paper presents a corrosion rate analysis and prediction of the remaining life of the Baruna Jaya IV research vessel using non-destructive testing (NDT) ultrasonic testing to improve ship safety aspects. The NDT ultrasonic testing was conducted on the ship's hull to evaluate the thickness and detect any hidden corrosion. The results were used to develop a corrosion rate model and predict the remaining life of the ship using a probabilistic model. The study found that the corrosion rate of the ship was high, and the remaining life of the ship was estimated to be less than five years. The study’s findings can be used to develop a maintenance and repair strategy to reduce corrosion and improve the safety of the Baruna Jaya IV research vessel.

Artificial Neural Network with multilayers is referred to as Deep Learning. As it is able to handle large amount of data, deep learning has become very popular in recent years. Classification, object tracking, estimation of different poses, text detection & recognition are various fields where deep learning is applied. Convolutional Neural Network(CNN) being one of the most important deep learning methods, has surpassed the traditional methods of classification.This paper presents a Supervised CNN, which is a machine learning algorithm used to classify images into different categories. In a few online registration processes, documents like Aadhaar,PAN,mark sheets etc need to be uploaded. Manual mistakes during upload can be committed as in; in place of Aadhar,some irrelevant document can be uploaded. Manual intervention to detect such mistakes is tedious.Hence we present an Intelligent Image based Document Classification using Machine Learning, where we have applied CNN to predict if the uploaded document is valid or invalid. The system is implemented on 900 images among which 500 are Aadhar images and remaining are PAN. The generated model recorded 90% accuracy to predict the Aadhar document and 93% in case of PAN.The same dataset is compared with Support Vector Machine(SVM) which displayed 88.88% overall accuracy.

Tuticorin area is populated with a large number of chemical industries and thermal power plants which contribute to changes in physicochemical characteristics of the coastal waters. Long term monitoring is required in order to understand the fluctuating trends of water quality in this area. The present study aimed to monitor the physicochemical characteristics of the coastal water at Tuticorin from 2012 to 2017. Sample collection was conducted for all the seasons of each year throughout the study period to understand the variations in physicochemical characteristics in the coastal water. A regression trend line was plotted based on the data which enables us to understand that water quality is deteriorating in the study area. Such long term studies are essential to determine the actual fate of any coastal area. Currently the area is yet to be termed as polluted; however measures must be taken to reduce the discharge of pollutants.

Published: December 2023

State estimation techniques appear in a plethora of engineering fields, in particular for the attitude estimation application of interest in this contribution. A number of filters have been devised for this problem, in particular Kalmantype ones, but in their standard form they are known to be fragile against outliers. In this work, we focus on error-state filters, designed for states living on a manifold, here unit norm quaternions. We propose extensions based on robust statistics, leading to two robust M-type filters able to tackle outliers either in the measurements, in the system dynamics or in both cases. The performance and robustness of these filters is explored in a numerical experiment. We first assess the outlier ratio that they manage to mitigate, and second the type of dynamics outliers that they can detect, showing that the filter performance depends on the measurements’ properties.

Authors: Kaka Hussain , Opute Prosper , Maboeta Mark
Published: December 2023

This study evaluated the ecotoxicity of metal-based fungicides under the current scenarios of global climatic change (20°C and 25°C) in single and binary mixtures of copper oxychloride (CuOx) [200, 500 and 1000 mg/kg] and mancozeb (MnZn) [44, 850 and 1250 mg/kg]. Endpoints assessed included mortality, growth, avoidance behaviour, and reproduction utilising standardised protocols (ISO and OECD). Mortality in the exposure groups only exceeded 10% in the CuOx1000 and CuOx1000 + MnZn1250 mg/kg groups in all temperature-moisture combinations. However, the mortality rate exceeded 10% only in the treatment with CuOx500 + MnZn850 mg/kg at 20°C30%. Relative growth rates in the CuOx and MnZn treatment groups decreased with increasing concentrations. In both CuOx and MnZn treatment concentrations at 20°C30% and 25°C50% conditions, avoidance response behaviour was greater than 80% throughout the exposure, except in CuOx200 mg/kg, MnZn44 mg/kg and CuOx200 + MnZn44 mg/kg. The reproduction of exposed earthworms in all treatment groups was concentration-dependent and influenced by varying temperatures and soil moisture conditions. No juveniles or cocoons were produced in the CuOx1000 mg/kg treatment at 25°C30%, indicating that copper oxychloride may be more toxic than mancozeb, especially in drought conditions. This study found that different temperatures and soil moisture levels altered the ecotoxicity of CuOx and MnZn. It can be concluded that climate change is likely to significantly impact the outcomes of metal ecotoxicity to earthworms and their ecological activities.
Effect of starch-based natural and synthetic binders on densification of sugar cane trash
Authors: Fatima Rohya , Irfan Muhammad , Fatima Hira
Published: December 2023

The growing demand of energy and the concurrent uplift in greenhouse gas emissions is attributed to the global waning of fossil fuels. In this regard, densification of biomass presents a viable and eco-friendly approach for producing solid fuels. Sugarcane trash is one of the promising biomasses used for energy production. This study aims to analyze and evaluate the effect of pretreatment and binder’s concentration on the densification of sugarcane trash. For this purpose, sugarcane trash is pretreated with hot water at 80°C in a 1:15 solid-to-liquid ratio (S/L) and densified by adding two different starch-based binders named as natural binder (low-grade broken rice) (NB) and synthetic binder (Maya) (SB) with three different concentrations i.e., 10%, 20% and 30%, followed with the palletization. After densification, the pellets are characterized by physical, mechanical, thermal, and structural properties. The results indicated that pellets with 10%SB presented optimum properties. Pellets with 10%SB pellets showed higher heating values (4301.17 Cal/g) (HHV), a crucial property for the design calculations or simulations of thermal conversion for biomass. The pellet strength is suggested to be linked with the composition of binder and biomass which is linked with the binding of binder and biomass material in the densified biomass. It is evident from the results that sugarcane trash pellets can fulfill energy requirements as per the needs of the present era keeping in view the green and sustainable environment. Thus, rather than burning the sugarcane trash which causes pollution, densified pellets are of great significance for bioenergy production.

Objective To explore the application and clinical significance of Hisense computer-assisted surgical system ( Hisense CAS) in preoperative lung volume measurement of pediatric pectus excavatum.
Methods The clinical data of 52 children with pectus excavatum admitted to the Affiliated Hospital of Qingdao University Medical College from January 2019 to January 2023 were retrospectively analyzed. Besides, CAS was used to perform three-dimensional reconstruction of the children's chest CT images. Measuring lung volume with CAS method was evaluated for its reliability and clinical significance by comparing the correlation between the reconstructed lung volume measurement results and the results of routine pulmonary function tests.
Results The mean values of CT-based CAS lung volume results were greater than those of pulmonary function tests, but the correlation with conventional pulmonary function results was statistically significant (P<0.05).
Conclusion CT-based CAS three-dimensional reconstruction lung volume measurement can serve as an effective method to clinically assess the lung volume of pediatric patients with pectus excavatum.
