Menstruation is a normal and necessary part of life, and maintaining proper menstrual hygiene is crucial for women's and girls' health as well as their right to access basic services for sanitation, hygiene, and reproductive health.Thesafe drinking water, sanitation, and hygiene (WASH) aspectof menstrual hygiene has significantly gained attention in recent times. In lowand middle-income nations, womenface significant menstrual hygiene management challenges. These problems stem from a lack of information and inadequate water, sanitation, and hygiene facilities.Women frequently struggle with a lack of access to menstrual hygiene products, or if they do, the high priceof sanitary pad render them unaffordable. The lives of vulnerable women are significantly impacted by stigma and period poverty, forcing them to use unhygienic alternatives like dried leaves and soiled old clothes as sanitary pads. The Menstrual Hygiene Day is observed on May 28 because women menstruate on average five days per month and menstrual cycles last an average of 28 days. 25 percent of World Bank education projects included menstrual hygiene management components, such as the provision of sanitary and hygienic restrooms or separate restrooms for boys and girls in their schools.To empower women and tackle misinformation, this study will contribute to raising awareness regarding the management of menstrual hygiene.

Published: January 2024

Citrus fruits are rich in differentflavonoid compounds. One of them is naringenin, which exhibits a huge variety of pharmacological benefits such as anti-inflammatory, antioxidant, anticancer, and cardioprotective properties. Butpoor bioavailability and solubility are the main reason for its limited clinical application. To overcome these limitations, several strategies, including complexation, formulation, and nanotechnology-based approaches, have been developed to boost its solubility and bioavailability.Among these approaches, nanoparticle-based delivery systems have shown remarkable potential in improving the therapeutic efficacy of naringenin. This review is based on the recent advances in the development of naringenin nanoparticles and their incorporation into drug delivery systems. We discuss over the numerous methods used to make naringenin more soluble and bioavailable, such as complexing it with cyclodextrins, combining it with lipids and surfactants, and adding it to polymeric nanoparticles. We also highlight the In-vivo and In-vitro studies conducted to check the efficacy of naringenin nanoparticles in various disease models. Finally, we conclude that the development of naringenin nanoparticles and their incorporation into drug delivery systems can be a promising strategy for the efficient delivery of naringenin, ultimately leading to improved health outcomes.

Parkinson’s Disease (PD) causes motor dysfunction that usually begins in the elderly population. The prevalence rate of PD is increasing significantly. Currently available therapies are able to manage the disease, however, they have certain side effects associated with long term usage. Hence, there is a dire need to bring therapies that can offer good treatment to PD with less side effects. Recent research has revealed that food supplements which are specifically rich in antioxidants and vitamins have shown better efficacy against PD with a better safety profile. Hence, the present study focuses on the role of nutraceuticals in treatment of PD. Nutritional supplements targeting PD pathology were explored between 2016 and 2022 through Scopus, google scholar and PubMed. The review deciphered the neuroprotective benefits of vitamins, minerals, natural compounds, and phytochemicals that might procrastinate or help in the prevention of PD’s progression by targeting some of the major pathological mechanisms such as oxidative stress, neuroinflammation, misfolding of alpha-synuclein, and mitochondrial dysfunction. Various studies indicating the potential of nutraceutical supplements are discussed in detail.

Authors: Bajracharya Kishor , Bhatta Dharm Raj , Thakur Raman
Published: January 2024

Escherichia coli, a growing health concern, produces extended spectrum β-lactamases (ESBL), which are causing public health onset infections in multiple countries. Geographical variations in the distribution and prevalence of ESBL-synthesizing E. coli have been observed, with India reporting the largest proportion (61%). The worldwide dissemination of ESBL-producing bacteria, along with the restricted availability of effective treatments, could exacerbate antibiotic resistance. The identification of ESBL synthesizing E. coli is crucial for its characterisation and epidemiology in specific geographical regions. In Nepal, a developing nation, research shows a high prevalence of antibiotic-resistant bacteria, particularly the ESBL strain. Our study aimed to identify ESBL-producing E. coli from patients with urinary tract complications from a tertiary hospital in Nepal. Out of 125 E. coli isolates, 15.6% were female and 1.2% male. The highest resistance was detected for ampicillin, cefazolin, cefotaxime, and ceftazidime, while less resistance was observed against nitrofurantoin, gentamicin, and imipenem. The study found that 51 (40.8%) E. coli isolates produced ESBLs, indicating a higher level of ESBL production among urinary tract infection patients.

Published: January 2024

Microplastics are small plastics measuring <5mm which, if they enter the water, can contaminate aquatic biota such as shrimp. The research aims to identify the number, shape and color of microplastics in shrimp bodies in vanname shrimp cultivation businesses on the East Coast of Aceh. Shrimp samples were taken from 3 stations, namely Pidie, Pidie Jaya and Bireuen. The samples were measured for weight and length, then prepared using H2O2 and H2SO4 in a ratio of 3:1 20 mL then incubated, heated, then filtered and identified using a Zeiss microscope with 40x magnification. The results obtained from shrimp body samples contained 2 types of microplastics, namely fiber and film. The most dominant microplastics at the three stations were 13 particles in the Pidie location, 9 particles in the Pidie Jaya location and 5 microplastic particles in the Bireuen location. The presence of microplastics that have entered the body of biota in the vannamei shrimp cultivation business is an early warning. So it is necessary to develop research on other consumption biota to determine the presence of microplastics and their impact if consumed by the public.

The painted spiny lobster, Panulirus versicolor, is an economically spiny lobster species on Simeulue Island. Fishing pressure on this species is suspected of experiencing overfishing, with indications that its size is getting smaller during the fishing season. Therefore, it is necessary to manage existing lobster resources. Several aspects that need to be considered in the sustainability of fisheries management are related to biological aspects, including the study of morphometry characters. This study aims to compare the morphometric characteristics of P. versicolor from three locations in Simeulue Island. The research was conducted from March to May 2023 with three sampling locations, including East Simeulue, Teluk Dalam, and South Teupah. A total of 90 samples were sampled using the random sampling method. To differentiate or classify the population, 15 parameters of spiny lobster morphometry were studied using discriminant function analysis. The results led to the assertion that P. versicolor from three separate places belonged to the same population but had distinct subpopulations. This condition is affected by the lobster samples collected from nearby areas. The investigation of the relationship between length and weight revealed that the growth pattern of P. versicolor in three locations were negative allometric, with length increasing faster than weight increasing.

Published: January 2024

River flow diversion is one of the most critical factors that must be considered for the success of dam construction. Soil and rock can support and load; therefore, understanding their strength and properties before tunnel construction is essential. Tunnel excavation and support depend totally on rock mass quality. Surface geological mapping, drill core analysis, and laboratory testing characterized the engineering geology conditions. Rock Mass Rating (RMR) and Japan Society of Civil Engineers (JSCE) methods were compared to determine rock mass quality and recommend excavation and support systems. Results showed that slightly weathered andesite lava and tuff lapilli lithologies dominate the tunnel alignment. Based on RMR, the rock masses quality along the tunnel alignment consists of poor and fair, and based on JSCE, the tunnel alignment consists of D I and C II rock categories with L and M massive rock types. Top heading and bench are recommended for tunnel excavation based on RMR, and the double bench and full-face method with an auxiliary bench cut are recommended for tunnel excavation based on JSCE. Although the characteristics of other support systems vary marginally, support systems based on RMR and JSCE recommend rock bolts and shotcrete as the primary tunnel support systems.

Published: January 2024

The Yogyakarta-Bawen toll road tunnel, located in Magelang Regency, Central Java Province, is a national strategic project that connects Central Java and the Special Region of Yogyakarta. It has geology resulting from volcanic processes, resulting in rocks with moderate aquifer properties and low to moderate permeability. The study covers 24 observation points, with 11 locations sampling groundwater for chemical analysis. The analysis results of hydrochemical facies are Na-K-HCO3. Water table depth varies from 623 m to 704 m above sea level, with the water table along the tunnel route at depths of 13-40 m above mean sea level, generally above the tunnel’s elevation. The groundwater flow pattern tends to move from southeast to northwest, perpendicular to the tunnel’s direction. Groundwater quality testing indicates that water in the research area falls under the category of fresh groundwater, based on electrical conductivity and total dissolved solids values. The overall acidity level is generally acidic, except at specific points. In general, the interaction of groundwater with concrete results in weak erosion. It can be concluded that the groundwater at the research location is shallow, situated above the planned tunnel elevation, exhibits hydrochemical facies variations, and has the potential to weakly erode concrete.

Authors: Alimin Baso Muhammad Ilham , Mauludin Luthfi Muhammad , Widiarnoko Gandhi
Published: January 2024

Cracks in concrete beams can significantly affect the performance of reinforced structures. To repair cracks in concrete, Traditional crack repair methods typically involve epoxy injection, but studies have suggested that epoxy may not fully restore the original strength. Therefore, concrete structure repair requires the development of new and more efficient materials. This study focuses on investigating the potential of Bacillus megaterium, a bacterium known for its self-healing properties in concrete. This bacterium has the capability to precipitate minerals like calcium carbonate, which can fill the cracks and increase the strength of concrete. Testing is carried out on reinforced concrete beams with existing cracks, sized at 100 mm x 100 mm x 500 mm. The specimens are divided into two groups, one repaired with epoxy injection and the other with bacterial injection, with varying additions of 10% and 15%. The research results show that the injection process with the addition of 15% bacteria is able to restore approximately 99.72% of the initial strength of the concrete beams. The results of this research contribute to the development of improved repair techniques that can restore the flexural strength of cracked concrete beams and extend the service life of concrete structures.

Published: January 2024

In 2021, Indonesia’s banana production is expected to reach 8.74 million tons. This substantial volume of bananas will generate a notable quantity of banana peel waste, constituting approximately one-third of the total banana fruit mass. Remarkably, banana peel waste retains 18.5% carbohydrates, which can be effectively converted into glucose, serving as a valuable feedstock for ethanol production. This research is focused on the ethanol production derived from Tanduk banana peel waste, employing a comparative analysis of the Separated Hydrolysis Fermentation (SHF) and Simultaneous Saccharification and Fermentation (SSF) techniques. Additionally, it explored varying raw material concentrations, specifically 200, 250, and 300 g/L. The SSF method integrated the use of cellulase enzymes, while the SHF method relied on HCl for the hydrolysis process. Microbial fermentation was facilitated by
Saccharomyces cerevisiae, with a fermentation duration of 96 hours and sample collection at 12-hour intervals. The results demonstrated that higher concentrations of banana peel waste yield increased glucose production during the hydrolysis process, consequently leading to greater ethanol produced. The concentration of 300 g/L banana peel waste is optimal for producing ethanol in both procedures. However, the SHF approach demonstrates a superior ethanol concentration of 51%, surpassing the 33.7% achieved by the SSF method.

Published: January 2024

This study attempts to examine the relationship between deposits, disbursed financing, the number of bank offices, and economic growth before and during the COVID-19 crisis. The time series data of Indonesian Islamic banking for the period from 2009 to 2022, has been utilized in this study, estimated using Auto Regressive Distributed Lag (ARDL). Deposits and disbursed financing respectively are the ratio of total deposits and total disbursed financing to nominal GDP. Economic growth is measured using Indonesia’s real GDP growth based on 2010 constant prices. The results show that in the long run, deposits have a very significant positive effect on economic growth. Meanwhile, financing and the number of bank offices do not affect economic growth. In the short term, except for the number of bank offices, real GDP, deposits, and financing contribute to the adjustment of changes in real GDP towards long-term balance, which takes approximately seven quarters. This study fills a gap in the literature on the role of Islamic banking on economic growth. This study also adds a new view of the role of Islamic banking in economic growth during the COVID-19 crisis. This study provides an important contribution to policymakers and other stakeholders.

This research investigates the innovative application of 3D printing technology in the production of geomembranes for laboratory-scale geotechnical experiments. Commonly, geotechnical research relies on the results of model testing. However, due to the high costs and complexity involved, full-scale model testing is rarely carried out. Geomembranes are essential components in various civil engineering projects, particularly in environmental containment and hydraulic barrier systems. In this research, the potential of 3D printing as an innovative method for producing geomembranes is carried out. Using a 3D printer, this research aims to prepare geosynthetic models with accurate geometric scales and tensile properties suitable for laboratory testing. A comparison was made between HDPE geomembranes and 3D printed geomembranes, to highlight their performance in a geotechnical laboratory environment. The research results show that 3D printed geomembranes show potential for applications in geotechnical research.

Halal tourism has increased and become a key tourism industry following the COVID-19 pandemic. Although this industry suffered greatly during the pandemic, it has made a promising return after the outbreak ended. Understanding how to sustain the tourism business in this recovering industry is critical. This study attempts to build a model of a sustainable strategy for the halal tourism industry from the tourist’s perspective, i.e., the tourists’ experience and their pleasure with the visit, by employing innovation and environmental concern as the determinants. Data from 442 inbound tourists visiting various Indonesian tourism destinations were used in this study. Using Partial Least Squares modelling, this study discovers that innovation and environmental concern are significant determinants of tourist experiences in tourism destinations, with innovation having a higher influence. Subsequently, tourist satisfaction is highly influenced by the attraction and halal products and services. Thus, this analysis implies that destination innovation and tourist concern for the environment are critical variables for the sustainable development of halal tourism.

The implementation of Russia’s energy strategy provides for the creation of an intelligent control system for active-adaptive electrical networks of the electric power complex, which contains a system for remote diagnostic monitoring of energy equipment, including metal load-bearing structures of electrical energy generation, transmission and consumption facilities. Promising in this regard is the use of a high-performance electromagnetic-acoustic method, which allows non-contact detection of metal defects and monitoring of their stress-strain state. But existing electromagnetic-acoustic diagnostic tools do not have sufficient sensitivity and information content to solve this problem. The article presents the results of experimental studies aimed at identifying and processing informative parameters of electromagnetic-acoustic transformation for the implementation of remote diagnostic monitoring of the stress-strain state and metal damage of power equipment. Based on the research results, it was proposed to use a frequency model formed as a result of spectral analysis of the electromagnetic-acoustic transducer signal as an integral parameter characterizing the state of the metal.
