Authors: Pratiwi Martin
Published: March 2024

This study aims to analyze the obstacles faced by doctors and midwives in minimizing the risk of fetal paralysis due to pregnant women's fear. The fear experienced by pregnant women can influence medical decisions made by doctors and midwives, leading to complications during pregnancy and childbirth. The research involves qualitative analysis from the perspectives of practitioners in various healthcare facilities. Findings reveal various relationships between factors and levels of maternal fear. Firstly, there is no significant relationship between the age of pregnant women and their fear levels. Secondly, maternal education significantly impacts fear levels, with highly educated pregnant women exhibiting lower fear levels, while those with lower education experience higher fear levels. Thirdly, maternal employment status is significantly related to anxiety levels, indicating that working pregnant women may experience higher levels of fear than non-working counterparts. Qualitative analysis indicates that nulliparous women tend to have greater fear of labor pain and pre-delivery concerns. BMI has a significant relationship with anxiety levels, suggesting that pregnant women with higher BMI may experience higher fear levels. Lastly, spousal support plays a crucial role in anxiety levels, with pregnant women receiving greater support from their husbands tending to have lower levels of fear.

Published: March 2024

Measurement of development in general uses the Human Development Index (HDI) indicator, but this concept cannot yet be a comprehensive measure of human development. The concept of HDI has an aspect of inequality and only measures the material session, while the spiritual is not measured. Therefore, the Islamic Human Development Index (I-HDI) is here to provide solutions for measuring human development in a complex way by measuring people's welfare through material, spiritual, and moral aspects. The purpose of this study is to explain the concepts and indicators of the human development index from an Islamic perspective and their relevance to maqāṣid al-sharī'ah. This research uses a method with a descriptive qualitative approach, which is an effort to understand the concepts found in the research process, using content analysis techniques and library research or literature review. The findings from this study indicate that the concept of the Islamic Human Development Index (I-HDI) provides an overview of the achievement of human development based on maqāṣid al-sharīʿah by measuring material and non-material aspects. I-HDI is an attempt to translate conventional development concepts into an Islamic perspective, in which the analytical tool used is based on the five maqāṣid al-sharīʿah dimensions as indicators of human needs both materially and spiritually. The I-HDI measurement is based on five maqāṣid al-sharīʿah, namely the protection and safeguarding of religion (ad-dien), protection of the soul (an-nafs), protection of the mind (al-aql), protection of offspring (an-nasl), protection of property (al-maal).

Published: March 2024

Remote sensing methods are receiving more and more attention during vegetation studies, thanks to the rapid development of drones. The use of indices created using different bands of the electromagnetic spectrum is currently a common practice in agriculture e.g. normalized vegetation index (NDVI), for which, in addition to the red (R), green (G) and blue (B) bands, in different infrared (IR) ranges used bands are used. In addition, there are many indices in the literature that can only be calculated from the red, green, blue (RGB) bands and are used for different purposes. The aim of our work was to objectively compare and group the RGB indices found in the literature (37 pcs) using an objective mathematical method (structured similarity index; SSIM), as a result of which we classified the individual RGB indices into groups that give the same result. To do this, we calculated the 37 RGB indexes on a test image, and then compared the resulting images in pairs using the structural similarity index method. As a result, 28 of the 37 indexes examined could be narrowed down to 7 groups - that is, the indexes belonging to the groups are the same - while the remaining 9 indexes showed no similarity with any other index.
Why Can’t Saint Victorinus of Poetovio Be the Author of the Homily “On the Ten Virgins”?
Authors: Khandoga Nikolay A.
Published: March 2024

The early Christian homily «On the ten virgins» for over 100 years has been a controversial work, since no strong argument has been presented by any scholar in favor of who is its author. The first group of researchers (for example, A. Wilmart, M. Špelič, M. Veronese and P. K. Dobrotsvetov) believes that its author is St. Victorinus of Poetovio, the first Latin interpreter of Holy Scripture. The second group of researchers (for example, A. Wlosok, M. Dulaey, R. Gryson and N. A. Khandoga) ascribes it to Pseudo-Victorinus of Poetovio, an unknown Latin exegete of the Gospel of Matthew. Proceeding from this, the article makes an attempt at a theological and philological analysis of several quotes from the homily «On the ten virgins» and the original works of St. Victorinus of Poetovio — the treatise «On the creation of the world», the fragment «On the life of Christ» and the interpretation of «On Revelation» — in order to identify the author of the homily. Important points in the answer to the question in the title in the article, becomes сhristology, eschatology and symbolic arrhythmology, since there is not a single one of the original works of Victorinus of Poetovio in which they are not given appropriate attention. However, in the homily «On the ten virgins» these theological themes are not adequately addressed.

Published: March 2024

Physicochemical properties of artisanal refined premium motor spirit (PMS), artisanal refined Household Kerosene (HHK), regular refined HHK and regular premium motor spirit (PMS) sampled from the Eastern Kolo Creek and a tank farm depot in Delta State, Nigeria was investigated. This was to compare the physicochemical properties of the samples with each other and their compliance with American Society for Testing and Materials (ASTM) standards. The finding revealed that the artisanal refined products quality did not comply with ASTM standards. The research octane number, motor octane number, Reid vapor pressure, and specific gravity of the standard PMS were ASTM compliant while only the final boiling point of the artisanal refined PMS was within ASTM range. Based on the findings, the artisanal refined products might have been poorly refined or adulterated and could constitute problems in automotive engines if used. However, this crude technology can be upgraded and the gasoline quality improved through alkylation, isomerization, and cyclization. Artisanal refiners should be trained to become proficient with the intent of becoming incorporated into the upstream petroleum sector.

The titration method can be applied to determine the complexation capacity between metal ions and ligands in natural water samples. The process involves the incremental addition of the metal to the sample containing a specific ligand, resulting in a titration curve that reflects the formation of complexes. The change in the curves slope indicates the saturation of the complexation capacity. In this study, the copper (II) ion was used due to its stability with organic ligands. The titration curve was analyzed to determine the complexation capacity (CC) and conditional formation constant (K) of the complex. Different mathematical treatments are proposed for this analysis. In the described experiment, differential pulse anodic stripping voltammetry was used to determine the complexation capacity of humic substances in natural waters. Experimental parameters such as pH, supporting electrolyte concentration, and volume of additions were previously optimized for the voltammetry technique. The obtained data were processed and analyzed, resulting in titration curves and voltammograms. The analysis of the curves allowed for the calculation of the complexation capacity and conditional stability constant of the formed complex. The results demonstrate the feasibility of the method as a didactic experiment for the voltammetric determination of natural water complexation capacity.

Today, environmental problems, especially soil pollution due to inorganic waste or waste that does not decompose, are a major problem and need to be solved, especially in developing countries with high populations such as Indonesia. One of the causes of soil pollution problems is the use of inorganic fibers such as glass fiber and carbon fiber. The use of materials that are not environmentally friendly in the industry will cause environmental problems due to nature's inability to decompose the glass fiber material in nature. The focus of this research is to reduce environmental pollution by using natural fibers such as abaca fiber as an alternative to inorganic fibers. This is due to its properties, namely: low density, good specific strength, low price, and a high biodegradable ability so that it can reduce glass fiber or carbon fiber waste that does not decompose. To support this, abaca fiber needs to be hydrophobic so that it becomes compatible with other materials when combined together with other materials. One of the ways that can be done is by alkaline chemical treatment and acetylation using KOH and CH3COOH. Chemical treatment was carried out by dipping abaca banana fibers into a solution of alkaline compounds and acetylated compounds KOH and CH3COOH with a concentration of 5 M and 10 M for 4 hours. After chemical treatment, the abaca banana fibers were characterized for mechanical properties using ASTM D 3379 standards to determine the tensile strength of the fibers and using an optical microscope to determine the microstructure of the abaca fibers.

"Finger stick" is a biscuit product with low nutritional content. Considering that tuna trimmings contain a high protein content, alongside advancements of science and processed food diversification technology, substituting tuna trimmings' protein concentrate is an innovation to enhance the nutritional quality of the finger stick product. The objective of this research is to determine the sensory attributes and chemical composition of finger stick with the addition of tuna trimmings' protein concentrate. The results of the organoleptic test for each treatment and for each organoleptic attribute showed that: biscuits without the substitution of fish protein concentrate, substitution with fish protein concentrate at 15%, 20%, and 25%, exhibit appearance scores of 4.4, 4.2, 4.5, and 4.7; aroma scores of 4.8, 4.4, 4.8, and 4.7; texture scores of 4.1, 4.2, 4.6, and 4.4; and taste scores of 4.7, 4.1, 4.8, and 4.6 respectively. Based on that organoleptic results, it is evident that finger stick with the addition of 20% fish protein concentrate has the best organoleptic value. Furthermore, proximate analysis was conducted for the best treatment (finger stick with the addition of 20% fish protein concentrate), and proximate results showed the content of moisture, ash, fat, protein dan carbohydrate were 3.00%, 1.09%, 16.52%, 32.72%, and 46.67% respectively.

Dysmenorrhea is lower abdominal pain that occurs during menstruation. According to the World Health Organization (WHO), 1,769,425 people (90%) experienced dysmenorrhea with an incidence of 10-15% of whom experienced dysmenorrhea with severe pain. Traditional medicine by consuming ginger can be an alternative as an effort to reduce menstrual pain (primary dysmenorrhea). The purpose of this study was to determine whether there was an effect of giving ginger (zingiber officinale) to decrease the intensity of menstrual pain (primary dysmenorrhea) in adolescent girls. The method used in this research is to use Systematic Literature Review (SLR). This study examines 9 journals for 2009-2021 consisting of 7 international journals and 2 national journals. All journals conducted studies related to the incidence of primary dysmenorrhea in adolescent girls. The original journal was obtained from the search results of the PuBmed and Google Scholar databases. The results of this study from 7 international journals and 2 national journals that have been studied can be seen that all research subjects, namely young women after giving the intervention experienced a significant decrease in menstrual pain (dysmenorrhea). This is because the active ingredients such as gingerol, shogaol, zingiberene in ginger rhizome can be used as antioxidants and anti-inflammatory.
