Penelitian ini bertujuan untuk mengetahui pengaruh berbagai jenis starter pada soyghurt sebagai pangan fungsional serta untuk mengetahui karakteristik kimia, mikrobiologi, dan organoleptik soyghurt dari berbagai jenis starter tersebut. Proses pembuatan soyghurt terbagi menjadi dua tahap utama: pembuatan susu kedelai dan pembuatan soyghurt. Tahap pertama, susu kedelai dibuat dengan menyortir dan mencuci kedelai. Kemudian, kedelai direndam dalam air (1:3) selama 12 jam, kemudian ditiriskan. Setelah itu, kedelai direndam lagi dalam air selama 30 menit dan dibilas dengan air mengalir. Kemudian, kulit ari dipisahkan dari kedelai. Kedelai kemudian diblender dengan air panas (85°C) selama 10 menit, lalu disaring dengan kain blacu. Sari kedelai kemudian dicampur dengan gula pasir dan bubuk susu skim. Susu kedelai dipanaskan hingga 80°C, lalu didinginkan hingga suhu 42°C. Tahap kedua, soyghurt dibuat dengan cara menambahkan bakteri starter ke dalam 100-200 ml susu kedelai, lalu menginkubasi campuran tersebut dalam inkubator sederhana selama 18 jam pada suhu 35-37°C. Terakhir, soyghurt didinginkan dalam kulkas pada suhu 4°C untuk menghentikan proses fermentasi. Penggunaan berbagai jenis starter tidak memberikan perbedaan yang signifikan pada soyghurt sebagai pangan fungsional. Namun, penggunaan berbagai jenis starter (dadih, biokul, CMR) memberikan pengaruh terhadap karakteristik kimia, mikrobiologi, dan organoleptik, meskipun tidak berbeda signifikan dalam kualitas soyghurt yang dihasilkan

Authors: Gunawan Yudhie Indra , Ahsani Nizam , Putra Aidil Syah
Published: February 2025

Purpose: This study examines the development of critical thinking skills among Indonesian English as a Foreign Language (EFL) students and their impact on research paper composition. It explores the unique challenges these students encounter, particularly in crafting research papers that demonstrate clarity, coherence, and analytical rigor.Methods: Employing a mixed-methods approach, the research combines quantitative data from structured surveys and qualitative insights from interviews and focus group discussions.Results: The findings reveal that while students recognize the importance of critical thinking in academic writing, many struggle with constructing well-supported arguments, integrating evidence effectively, and adhering to academic conventions. The study identifies key barriers, including limited argumentation skills, restricted academic vocabulary, insufficient exposure to critical reading practices, and unfamiliarity with academic genres and formatting standards. Despite these challenges, students who actively engage in critical reading and structured analytical exercises show marked improvements in their writing coherence and argument development. The results suggest that targeted interventions such as integrating critical thinking exercises into curricula, providing scaffolded writing instruction, and enhancing feedback mechanisms can significantly enhance students’ research writing proficiency.Conclusions: The paper concludes with actionable recommendations for educators, institutions, and policymakers to strengthen critical thinking instruction in EFL classrooms, ultimately improving academic writing outcomes in Indonesia.

Published: February 2025

Spinning factory consumes highest amount of electrical power than Weaving, Knitting, Dyeing and Garment unit of Textile Industry. A typical spinning unit of 20000 spindles requires about 2 Megawatt (MW) connected power to run the process machinery. Power is also a major cost component of yarn production after raw materials and hence reduction of power cost is an utmost concern for the management of spinning unit. This investigation aims to reduce power consumption of Ring frame using Plastic T-in cylinder. 2850 meters length of a 30 Ne yarn fineness was spun in a Ring frame with T-in cylinder, and the same length of that yarn was also produced by a Ring frame with Metallic T-in cylinder from the same feed material (Roving). Power consumption was measured by a Digital power meter during the production of yarn at different set lengths. The power consumption was 39.5 KWH and 37.3 KWH corresponding to Metallic and Plastic T-in cylinder. The reduced power consumption suggests that the setting up of new spinning unit can be considered to be designed with Ring frame with Plastic T-in cylinder.

Les arbres, les scientifiques, les artistes et leurs instruments perçoivent l'écoulement de l'eau. Les arbres prennent des risques pendant la saison de croissance soit en augmentant leur transpiration (ou flux de sève), soit en se restreignant. Les vaisseaux se dilatent, se contractent. L'eau est tirée vers le haut, du sol vers l'air, en passant par la tige des arbres. Mais en cas de sécheresse, ces connexions peuvent être brisées et les arbres peuvent en mourir.

Les scientifiques et les arbres perçoivent ensemble les conditions environnementales. En raison de ses fluctuations régulières, le processus peut être comparé aux pulsations du cœur, au ralenti. Pendant la journée, les arbres transpirent, ce qui entraîne un mouvement de l'eau dans le tronc. La quantité d'eau diminue de l'extérieur vers l'intérieur de l'aubier et, en raison de la déshydratation, le tronc se rétrécit. Pendant la nuit, la tige gonfle en raison de la réhydratation et de la recharge en eau. Traction, canalisation, diminution, expansion. Les pulsations relaient ces fonctions en corrélation avec la lumière et l'humidité atmosphérique.

Les scientifiques surveillent la tige de l'arbre à l'aide de sondes chauffées et entourent les troncs d'arbres de sangles et de machines. Un dendromètre quantifie les changements de taille du tronc dus au gonflement, au rétrécissement et à la croissance, en les exprimant en microns. Le 3 juillet 2020, pour un érable à sucre mature, son diamètre était de 355 000,13 μm à 15 h et de 355 062,47 μm à minuit. Le même jour et pour le même arbre, un capteur de flux de sève associé à un enregistreur de données et à des algorithmes a rapporté la transpiration en centimètres par heure : 1,05 cm/h à 5 h et 14,89 cm/h à 14 h. L'échantillonnage le démontre, l'arbre change continuellement. L'expérience de l'arbre est partagée avec les êtres humains. Il s'agit ici de co-construire, à partir des expériences, les connaissances portant sur et dans des climats changeants, s'ouvrant aux multiplicités et favorisant les écotechnologies en pratique : celles de l'arbre, de l'instrumentation et du milieu de cooccurrence. Les visualisations tissent les relations issues de cette rencontre entre les modes de captation quantitative et qualitative, une interopérabilité avec les ordinateurs. S'agit-il de la fidélité de données ?

Analyzing the Impact of Delta State Capital Territory Development on Land Use Change in Local Communities Using Remote Sensing, GIS, and Qualitative Survey
Authors:   Dennis Osadebay University, Asaba, Nigeria., Ashikodi Marian , Chokor Anthony ,   University of Benin, Benin, Nigeria.
Published: February 2025

This paper demonstrates the spatial and temporal dimensions of land use change in
Delta State Capital Territory and derives the policy implications and lessons for the
planning and implementation of sustainable urbanization. It is based on the study which
combined remote sensing, geographic information system and qualitative field survey.
Satellite data generated by Landsat 5(TM), Landsat 7 (ETM+) and Sentinel 2B (MSI)
for the years 1990, 2011 and 2020 were used. This was also analyzed using Erdas and
ArcGIS 10.6.1 software. Results from this Geographic Information Systems (GIS)
analysis were triangulated with data from key informant interviews and focus group
discussion. The study hypothesis was tested by applying student t-test on data sets
derived from the GIS analysis. Findings of the research include reduction of
undeveloped land areas from 16% in 1990 to 0.09% in 2020 and increase in built –up
land areas from 7% in 1990 to 29% in 2020. The observed unorganized spread of
urbanization in the capital territory is linked to the absence of Master Plan and the fact
that the Delta State Capital Territory Development Agency was established 24 years
after the territory was designated. The paper concludes that the Delta State Capital
Territory development process does not fully conform to the growth center theory of
urbanization. It is imperative for urban planners and policymakers to formulate and
implement Master Plans upfront for proper land zoning and sustainable land use. In
addition, the growth center theory should be applied contextually for sustainable
urban development.

Skin-lightening practices are increasingly common among young adults, influenced by
societal beauty standards, cultural traditions, and economic factors. However, these
practices pose serious health risks, including skin damage and psychological distress.
Limited awareness of these dangers, coupled with regulatory gaps, exacerbates the
issue, necessitating targeted interventions. This study investigates the health risks and
socio-demographic factors influencing skin-lightening practices among young adults
in Ilorin West, Nigeria. A cross-sectional survey was conducted with 450 participants,
primarily aged 18–23 years. Structured questionnaires captured data on socio
demographic characteristics, product usage, health effects, and influencing factors.
Statistical analyses, including chi-square tests, were used to assess associations
between socio-demographic variables and skin-lightening prevalence. Findings
indicate a high prevalence (65.3%) of skin-lightening, particularly among young,
single, female students with secondary education. Reported adverse effects include skin
irritation (37.8%) and hyperpigmentation (25.3%). Alarmingly, 76.2% of respondents
were unaware of the long-term health risks. Cultural and economic factors significantly
influenced behavior, with affordability and tribal norms playing key roles. The Hausa
ethnic group exhibited the highest prevalence (73.5%), while usage was highest among
individuals aged 21–23 years. These findings underscore the urgent need for public
health interventions. Raising awareness through culturally sensitive education
campaigns, enforcing stricter regulations on harmful products, and engaging social
influencers can help reshape societal beauty norms. Policymakers must implement
stronger controls on the production and sale of hazardous skin-lightening products.
Additionally, promoting self-acceptance and healthier beauty ideals through
community-based advocacy can reduce reliance on harmful practices. This study
highlights the critical health risks associated with skin-lightening among young adults.
Addressing the cultural and societal drivers of these behaviors can improve physical
and mental health outcomes, fostering a healthier perception of beauty.

In view of the proliferation of SMEs, their compliance with extant environmental
regulations is important in reducing the environmental impact of their production
activities. Literature on the level and frequency of compliance with regulations to
inform enforcement policy is however scarce. In addition, information on the impact
of size on compliance within the SME business category is insufficient. This study
filled these gaps by the examination of level, frequency and impact of size on
compliance among 256 SMEs in the food and beverage sector in Southwestern Nigeria.
The study employed a structured questionnaire survey distributed to the managers of
the SMEs across three states. The results showed that some SMEs were not in
compliance with extant regulations. About 15% of the SMEs were not in compliance
with solid waste management regulations, while 15.3% have no air pollution measures.
In addition, 15.8% of the firms did not treat waste water discharge from production
processes. The study also indicated that 24% of SMEs failed to conduct Environmental
Impact Assessments (EIAs), Results also showed (on a 5-point Likert frequency scale
from never to always) that respondents sometimes; were in compliance with continuous
monitoring and reporting of environmental performance (3.39), adhered to sustainable
supply chain practices (3.38) and were in compliance with stakeholder involvement in
the firm’s environmental initiatives (3.38). In addition, the small-sized firms were more
compliant than medium-sized businesses in having a waste management plan,
integrating sustainability into business operations, preparing periodic environmental
audits and assessments, and responsiveness to community complaints on wastes. The
study recommended more regular and stringent enforcement policy mechanisms to
curb the hazardous activities of SMEs.

This study assessed OCP residues in rice grains and soils from various rice-producing
regions in Nigeria, aiming to estimate human exposure and associated health risks from
rice consumption. Samples were collected from Hadejia (Jigawa), Makwaro (Kano),
Pategi (Kwara), Igbemo (Ekiti), Isoku (Ogun), and Akeke (Edo) using a stratified
random sampling technique. Gas Chromatography-Mass Spectrometry (GC-MS)
analysis revealed α-Lindane, β-Lindane, γ-Lindane, and δ-Lindane were only present
in rice from Ogun, while Endosulfan II was detected across all locations, with
concentrations ranging from 1.819 mg/kg in Igbemo rice to 20.706 mg/kg in Costus
rice from Kano. Other OCPs, such as Aldrin and Dieldrin, also varied significantly
across regions, with Aldrin levels peaking at 0.224 mg/kg in Ogun. The analysis
highlighted substantial non-carcinogenic risks associated with OCP exposure,
particularly in Ogun and Kano, with Heptachlor presenting the highest Target Hazard
Quotient (THQ) values. The Lifetime Cancer Risk (LCR) analysis showed Ogun with
the highest cumulative risk at 0.016107, indicating a critical public health concern.
Overall, the findings underscore the urgent need for monitoring and regulatory
measures to mitigate OCP exposure risks in rice consumption, particularly in regions
where LCR and THQ values exceed safety thresholds.

using solar energy. A total of 53 poultry farmers that have adopted this innovation were
selected through a snowballing sampling technique from 6 different states in Nigeria.
Primary data was used, and the objectives were analysed using profitability ratio, gross
margin analysis, stochastic frontier analysis, OLS regression and a 4 -point Likert scale
respectively. The results revealed that poultry farmers kept about 67% of the total
revenue generated from the sales of their output and a Return on Investment of 78 kobo
on every ₦1 invested was realized, a technical efficiency rating of 93% was recorded
on average for the poultry farmers and this implies that the poultry farmers were highly
resource use efficient dropping only 7% due to inefficiencies. This study also revealed
that cost of feeds, cost of birds, cost of labour and the solar energy technology were
very significant in determining the resource use efficiency. Finally, the high cost of
input was identified as the most significant challenge faced by the poultry farmers
assessed. It can be concluded that adopting solar energy on poultry farms presents a
highly profitable solution. Furthermore, this shift offers potential benefits for
policymakers by reducing the sector's dependency on conventional energy sources,
promoting sustainable agricultural practices, and supporting the formulation of policies
that incentivize renewable energy adoption to enhance food security and economic
resilience.

In modern life, composite indices are increasingly utilized to synthesize multidimensional data into simplified metrics, aiming to facilitate comparisons and decision-making in areas such as public policy, health, and sustainability. However, their construction faces significant methodological challenges, such as subjectivity in selecting and weighting indicators, information loss during aggregation, and increased variance, compromising statistical differentiation. This article critically examines these limitations, with a special focus on the robustness of composite indices. The literature review highlights contributions that underscore the risks of implicit weights and biases resulting from aggregation formulas. To mitigate these issues, the article proposes methodological refinements, including greater transparency in weighting, sensitivity testing, and the use of advanced statistical techniques such as principal component analysis. By addressing the limitations and alternatives to the construction of complex indices, this article aims to contribute to the development of more robust and reliable composite indices, reviewing recommendations present in the literature and offering suggestions to enhance their methodological foundations and interpretative validity.

Power Transformer Fault Diagnosis Based on Multi Class SVM and IPSO
Authors: Bai Zihan , Zhao Ziyu , Xu Mingshen
Published: February 2025

This article focuses on classifying a variety of faults in power transformers with high precision, using an Improved Particle Swarm Optimization-Support Vector Machine (IPSO-SVM) system designed for fault diagnosis. The process begins with the identification of five distinct gases dissolved in oil, serving as diagnostic features. Minimal output encoding is then used to construct multiple binary support vector machine (SVM), facilitating a multi-class classification of transformer faults. While other studies often combine traditional Particle Swarm Optimization (PSO) algorithms with SVMs, our approach employs an enhanced PSO algorithm. This improved algorithm allows for the optimization of inertia and learning factors, values of which adapt based on iteration counts. The PSO is then leveraged on the optimization of the penalty factor and the radial basis function of SVM, thereby improving its classification performance. Simulation results indicate that our IPSO-SVM methodology achieves 90% and 92% accuracy in training and testing sets, respectively. This method significantly enhances the accurateness oftransformer malfunction diagnosis, exhibiting superior diagnostic precision compared to traditional power transformer malfunction diagnosis methods.

Authors: Xu Mingshen , Zhang Teng , Li Xiaotian
Published: February 2025

Power load forecasting is crucial for the economic dispatch and safe operation of power grids, yet the fluctuating and unstable nature of power load data often limits the accuracy of traditional single-model approaches. This paper presents an integrated learning model designed to improve forecast-ing accuracy and stability by addressing these challenges. The model in-corporates improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN), a vector-weighted average optimization algorithm (INFO), convolutional neural networks (CNN), bidirectional long short-term memory (BiLSTM), and random forest (RF). By thoroughly analyzing and preprocessing the data, the approach effectively handles its non-linear, non-stationary characteristics. The combination of CNN and BiLSTM enhances the model’s ability to capture temporal and spatial features, while RF strengthens generalization. The INFO algorithm dynamically adjusts weights and parameters during training, resulting in significantly improved predictive performance. Experimental results on data from the Australian electricity market confirm that the proposed model outperforms existing approaches in key performance metrics, showcasing its effectiveness and potential for practical applications in power load forecasting.
