Abstract
This research explores the lateral behavior of trapezoidal corrugated steel shear walls (CSSW) with double plates with two different corrugation angles by employing cyclic loading in the ABAQUS finite element software. The samples studied in this research were a one-story, one-span frame with three trapezoidal corrugated double plates with angles of 30, 45, and 60°. Three thicknesses of 2, 3, and 4 mm were considered to explore the impact of the thickness of the infill plates. The obtained results have shown that the change in the angle of one of the double corrugated plates has no significant effect on the shape of the hysteresis curve and the amount of equivalent viscous damping. Nonetheless, it can lead to a change in the value of maximum resistance and energy absorption. The outcomes displayed that double corrugated steel shear walls (DCSSW) with 60° corrugation angles have the highest maximum resistance and energy absorption. After this sample, in the samples with infill plates with thicknesses of 2, 3, and 4 mm, samples 30–45, 45–60, and 45–60, respectively, have more maximum resistance. In addition, samples 30–60, 30–60, and 45–60 have the highest energy absorption after the sample 60–60°.

Abstract

Background
The necessity of prophylactic lateral neck dissection for cN0 papillary thyroid carcinoma (PTC) remains debated. This study aimed to compare traditional nomograms with machine learning (ML) models for predicting ipsilateral lateral and level II, III, and IV lymph node metastasis (LNM).

Methods
Data from 1616 PTC patients diagnosed via fine needle aspiration biopsy from Hospital A were split into training and testing sets (7:3). 243 patients from Hospital B served as validation set. Four dependent variables—ipsilateral lateral, level II, III, and IV LNM—were analyzed. Eight ML models (Logistic Regression, Decision Tree, Random Forest-RF, Gradient Boosting, Support Vector Machine, K-Nearest Neighbor, Gaussian Naive Bayes, Neural Networks) were developed and validated using 10-fold cross-validation and grid search hyperparameter tuning. Models were assessed using 11 metrics including accuracy, area under the curve (AUC), specificity, and sensitivity. The best was compared with nomograms using the Probability-based Ranking Model Approach (PMRA).

Results
RF outperformed other approaches achieving accuracy, AUC, specificity, and sensitivity of 0.773/0.728, 0.858/0.799, 0.984/0.935, 0.757/0.807 in the testing/validation sets respectively for ipsilateral LLNM. A streamlined model based on the top ten contributing features that includes ipsilateral central lymph node metastasis rate, extrathyroidal extension, and ipsilateral central lymph node metastasis number retained strong performance and clearly surpassed a traditional nomogram approach based on multiple metrics and PMRA analysis. Similar results were obtained for the other dependent variables, with the RF models relying on distinct but overlapping sets of features. Clinical tool implementation is facilitated via a web-based calculator for each of the four dependent variables.

Conclusion
ML, especially RF, reliably predicts lateral LNM in cN0 PTC patients, outperforming traditional nomograms.

Abstract. Hendri, Nugroho JD, Rahmadaniarti A, Nurlaela, Prabawardani S, Luhulima FDN, Gardiner C, Hematang F. 2024. Biodiversity conservation, food security, and carbon storage potential of local agroforestry practices in the Bird’s Head Region of Papua, Indonesia. Biodiversitas 25: 4315-4332. Local Agroforestry Practices (LAPs) in the Papua Region, Indonesia, which are still under-researched, play a crucial role in biodiversity conservation through sustainable crop rotation systems, intensification, and technological adaptability. This research aims to develop an improved intensification model that integrates these LAPs with sustainable agroforestry practices, biodiversity conservation, food security measures, and adaptive responses to climate change and extreme conditions. The study utilized the Focus Group Discussion (FGD) method, demonstration plot, Participatory Rural Appraisal (PRA) type selection of LAPs, and economic and allometric equations. The findings revealed a meticulous species selection process that considered biodiversity, resulting in 24 species classified as Least Concern (LC), 2 species classified as Near Threatened (NT), 1 species classified as Vulnerable (VU), and 2 species classified as Endangered (EN). The LAPs implementation achieved a Food Security (FS) score of 45,23% and 38.47% for Only Used (OU). Importantly, the total revenue generated by the LAPs design in Moswaren, Aimas, and Manokwari Village is nearly the same, with an average of Rp 16,327,231.00, Rp 16,640,731.00 and Rp 15,848,675.00 per year, respectively. This represents a significant economic impact, with the increase being 2.93-5.04 times greater than typical LAPs; this significant contribution to biodiversity conservation is a testament to their value. The aggregate carbon content across the three sites varied between 223.80 and 279.05 tC/ha.

Abstract. Nelly C, Fitriyana L, Santi TD, Saudah. 2024. Diversity of traditional vegetables and spices as local food security for the Gayo Tribe, Aceh, Indonesia. Biodiversitas 25: 4699-4711. Food is a fundamental necessity that is essential for human sustenance. The variety of traditional vegetables and spices, harvested from forests, fields, or home gardens, is critical to local food security. This study aimed to investigate the variety and utilization of local vegetables and spices by the Gayo community in Pining Sub-district, Gayo Lues District, Aceh, Indonesia and their contribution to sustainable food security. A field survey and semi-structured interviews five villages identified 75 taxa of vegetables and spices from 36 families with Zingiberaceae being the most dominant. The findings show women, who made up 68.0% of respondents, are key knowledge holders, passing down traditional plant knowledge through daily practices. Species such as Cocos nucifera L. and Etlingera elatior (Jack) R.M.Sm. showed the highest use value and frequency, underscoring their cultural and nutritional significance. However, the Gayo community faces threats, including land-use changes and the loss of traditional knowledge among the younger generation, jeopardizing plant conservation and sustainable food systems. Strategies such as sustainable agroforestry, local seed banks, and restoring traditional knowledge are essential to preserve biodiversity and ensure local food security. This research highlights the importance of preserving the diversity of traditional vegetables and spices as key elements of food security and cultural heritage.

Abstract. Calderon AMA, Morilla LJG, Estaño LA. 2024. Species diversity of brackish water fishes and their associated endoparasites from the Tamala Fish Sanctuary of Kapatagan, Lanao del Norte, Philippines. Biodiversitas 25: 4745-4755. Fish plays a vital role in the aquatic ecosystem and is integral to human nutrition and food security. The survey of brackish water fishes and its associated endoparasites in Tamala Fish Sanctuary, Kapatagan, Lanao del Norte, Philippines, was carried out in August 2023 in three coastal barangays of Taguitic, Margos, and Lapinig. A total of 174 individuals belonging to 5 families were collected, comprising six species: Chanos chanos, Oreochromis niloticus, Oreochromis mossambicus, Glossogobius giuris, Mugil cephalus, and Ambassis nalua. Among the recorded species, M. cephalus harbors the highest abundance (35.63%) and can be found in all three sites, while O. mossambicus is the least abundant (2.87%) and is restricted to only one site. Endoparasites in these fish species, comprising nematode, trematode metacercariae, and Acanthogyrus sp., were also recovered in this study. The prevalence of infection is reported to be highest in Barangay Taguitic (42.86%), followed by Margos (25.45%) and Lapinig (10.48%). Among the species, C. chanos (35.71%) recorded the highest infection rate, followed by G. giuris (29.73%), O. niloticus (26.09%), and M. cephalus (1.61%). In contrast, two species, O. mossambicus and A. nalua, were not infected with endoparasites. Adult species (24.74%) also exhibit the highest prevalence rate compared to juveniles (9.09%). In terms of intensity, Lapinig (7.64±0.23) has the highest value in the site, followed by Margos (1.5±0.10), then Taguitic (1.4±0.17). With regards to species, G. giuris harbors the highest mean intensity (7.82±0.62), followed by C. chanos (1.6±0.17), O. niloticus (1.42±0.10), and M. cephalus (1±0.02). Furthermore, adult fish species (4.33±0.25) exhibit higher mean intensity than juveniles (1.41±0.04). The mean intensity per site, species, and age were significant (p<0.05). Endoparasites in these brackish water fish hosts are an excellent biological indicator in aquatic ecosystems. This study provides baseline data for further investigation on fish species diversity and its endoparasites in the area.

Abstract. Miharja J, Atmowidi T, Priawandiputra W, Perwitasari D, Kahono S. 2024. Species richness and nest entrance characteristics of stingless bees (Hymenoptera: Apidae: Meliponini) in Ujung Kulon National Park, Banten, Indonesia. Biodiversitas 25: 4961-4970. Stingless bees (Hymenoptera, Apidae, Meliponinae) are distributed in tropical and subtropical regions. Ujung Kulon National Park (UKNP), a conservation area of flora and fauna in the western part of Java, was designated by UNESCO in 1992 as a Natural World Heritage site. This study measured the species richness, nesting site, and nest-entrance characteristics of stingless bees in UKNP. Samplings of stingless bees were conducted by road sampling and based on the information from officers of UKNP and the local communities from June to December 2023. Results showed that 163 colonies of stingless bees were found belonging to four species, i,e., Tetragonula laeviceps, Tetragonula fuscobalteata, Heterotrigona itama, and Lepidotrigona terminata. Based on the number of colonies, L. terminata was the most dominant (44%), followed by T. laeviceps (41%), T. fuscobalteata (12%), and H. itama (3%), respectively. The nest of T. laeviceps was found in residential house cavities, bamboo and tree holes, and old and abandoned ant nests, showcasing their adaptability and resourcefulness. Meanwhile, the nest of T. fuscobalteata was found in the rock holes and tree cavities; L. terminata and H. itama nests were found in tree cavities. The unique nest entrance characteristics of each species further highlight their fascinating adaptability. This study showed a new distribution record of stingless bees in Ujung Kulon National Park, Banten, Indonesia.

Abstract. Pratama R, Suwandi S, Muslim A, Mulawarman. 2025. Diversity of Ceratocystis fimbriata causing canker and wilt disease on Cupressus sempervirens (Italian cypress) in Indonesia. Biodiversitas 26: 278-287. In 2022-2023, new diseases were observed on Cupressus sempervirens in South Sumatra, Indonesia, with the disease incidence increasing from 17.6% to 26.5% in 2023. Initial symptoms, included stem cankers, black lesions on sapwood and vascular tissue, discoloration and partial wilting of leaves, and eventual complete drying, leading to plant death. The objective of this study was to isolate and identify the fungal pathogen causing wilt disease in C. sempervirens trees using morphological characterization and DNA sequencing. In 2022-2023, a disease survey was conducted in six districts of South Sumatra. The results showed that six out of ten locations were infected, with disease incidence ranging from 4.1% to 17.6% in 2022, increasing to 2% to 26.5% in 2023. Pathogen identification employed a polyphasic approach, combining morphological and molecular characteristics from specific genomic regions (the internal transcribed spacer (ITS) and ?-tubulin). Both the morphological features (including a globose base with a long neck-ended tip with ostiolar hyphae, cylindrical conidia, and hat-shaped ascospores) and phylogenetic analysis identified the isolates as Ceratocystis fimbriata. ITS gene sequences indicated that all the isolates belonged to the ITS5 haplotype. In pathogenicity test, pathogen caused mortality in C. sempervirens, Acacia mangium, and Artocarpus heterophyllus plants. The implications of these findings are significant, as they can potentially lead to the development of effective control measures. To our knowledge, this is the first report of Ceratocystis spp. causing wilt disease on C. sempervirens in South Sumatra.

Abstract. Purwoko Tj, Sari SLA, Mahadjoeno E, Sunarto. 2017. Bioethanol production from rice and corn husks after enzymatic and microbes hydrolysis and yeast fermentation. Bioteknologi 14: 19-23. Bioethanol is a renewable resource that can be produced from fermented cellulosic biomass. The use of lignocellulosic materials from agricultural wastes provides a low-cost fermentative substrate. Lignocellulosic ethanol production involves acid or enzymatic hydrolysis. The enzymatic hydrolysis cost higher, however in environmental issue this step is favorable. The purpose of this research was to compare bioethanol production after microbes and cellulosic enzymes hydrolysis following yeast, Saccharomyces cerevisiae, fermentation from rice and corn husks. The rice and corn husks (1 kg) were each suspended in water until the volumes reached 5 L. The sample mixtures were treated with 2.5 mg/L cellulases, 5 g/L multienzymes, and 5 mL/L EM4 respectively. The mixtures were stirred for 24 hours at pH 5.7 and 35°C. After hydrolysis, the samples (100 mL) were treated by 1, 2, and 3 % w/v Baker’s yeasts. The samples were fermented with incubator shaking for 6 days at 30°C, 90 rpm, and pH 6.5. Sugar concentrations were determined by dinitrosalicylic acid (DNS) colorimetric method. Bioethanol production and specific gravity method were then compared to IAOC Ethanol Table. Sugar concentrations and bioethanol production after multienzymes hydrolysis of rice and corn husks. There were 6.54-6.81 mg/mL and 3.17-3.54 mg/mL, respectively. Sugar concentrations of rice and corn husks after multienzymes hydrolysis treatment was higher than EM4 and cellulases hydrolysis treatments. Therefore, bioethanol productions of rice and corn husks after multienzymes hydrolysis and yeasts after 2 days fermentation were higher than the others.

Abstract. Himawati E, Riyadi NH, Manuhara GJ. 2018. The effect of adding coconut shell liquid smoke by distillation and redistillation on the chemical, microbiological, and sensory properties of pindang layang fish (Decapterus spp.) during storage. Bioteknologi 15: 84-91. Pemindangan (salted-boiled fish) is one way of processing fish with a combination of treatments between salting and boiling. But pindang layang fish (Decapterus spp.) only has a shelf life of about 2-4 days which quickly undergoes a process of decay. So we need a preservation technique that can minimize damage to pindang Decapterus spp.. Liquid smoke is a chemical that results from the distillation of smoke from burning biomass and acts as a disinfectant. Phenol, carbonyl, and organic acids in liquid smoke play an important role in fish preservation. Distillation liquid smoke is obtained from the first pyrolysis and has a fairly high content of tar compounds, while redistillation liquid smoke is the second product from the first distillation. The purpose of this study was to determine the effect of adding coconut shell liquid smoke by distillation and redistillation on the chemical properties (moisture content, pH, phenol), microbiological properties (TPC), and sensory properties (color, odor, texture, and overall) of pindang Decapterus spp. during storage. As well as knowing the best concentration of distillation liquid smoke (1%, 2%, 3%) and redistillation (25%, 30%, 35%) in maintaining the quality of pindang Decapterus spp. during storage. The analysis was carried out for 4 periods on 0,2,4,6 days. The experimental design used was a completely randomized design (CRD). The data obtained were analyzed by ANOVA at =5% and continued with the DMRT test if there was a significant difference. The results showed that the chemical characteristics were water content (61-67%), pH (5-7), phenol (0.226-0.566%), while microbiological characteristics (TPC) (1.85.104-3.15.105 Cfu/g). The sensory characteristics (color, odor, texture, and overall) of pindang Decapterus spp. with redistillation liquid smoke treatment were preferable to distillation liquid smoke treatment. In terms of chemical, microbiological, and sensory properties, the treatment of redistillation of liquid smoke was significantly different from that of the distillation of liquid smoke. A review of the chemical and microbiological properties of the 35% redistillation liquid smoke treatment was the best treatment, while from the sensory properties, the 30% redistillation liquid smoke treatment was the most preferred by the panelists compared to other treatments.
Regime Change: The Need for Scientific Critical Consciousness
Authors: Mirza Usama Javed 
Published: February 2025

Abstract
Concerns about nuclear technology or global warming are among myriad socio-scientific issues in the world that students are given very poor preparation with which to engage critically. By not tackling them head-on, curricula risk dangerously misleading students about the nature of science, its legacy and place in the world; aggravating socio-economic inequality perpetuated by centuries of European colonialism of the Global South. These misleading ideas include Eurocentrism, viewing religion as irrational and Western science as superior to indigenous knowledge systems.
In an effort to identify how to inculcate the dispositions in students to counter oppressive ideas taught under the guise of science, this paper presents a theoretical framework and curriculum for inculcating a scientific critical consciousness (SCC). SCC is presented as the ability to perceive these oppressive ideas relating to science, and to take action to counter them. The theoretical framework is developed by adapting ideas from and critiques of Freire (2017), Greene (2011), Boler and Zembylas (2002), Anyon (2009) and Biesta (1998).
This article outlines how the curriculum, teaching and assessment methodologies of traditional science classes can be enhanced to inculcate SCC. This is illustrated by presenting a “revamped” curriculum of the Cambridge Assessment International Education (CAIE) O’ level physics, complete with a learning outcomes and assessment framework. Parts of this curriculum were informally pre-piloted at a private school in Islamabad, Pakistan, and at a public school in Harlem, New York. These pre-pilot experiences confirm the challenges predicted by research in implementing emancipatory curricula, e.g. that social taboos prevent open discussion of sensitive socio-scientific social justice issues. They also indicate much promise from even partial inclusion; students demonstrated changing perspectives and motivation to tackle social justice issues, and there was significantly increased student engagement—including by those who were previously disinterested in science.
Book Review: Decolonizing the Mind (by Sandew Hira)
Authors: Delices Patrick 
Published: February 2025

Abstract
Although the dominant narratives in the world of academia are from the vantage points of primarily white males from the West (Europe and the United States), there is an alternative narrative that is being discussed in many parts of the world that is challenging the colonial perspectives of the West. This non-Westernised narrative is deeply discussed in Decolonizing the Mind: A Guide to Decolonial Theory and Practice by decolonial scholar, economist, historian and activist Sandew Hira. The aim of Hira’s Decolonizing the Mind is to deeply engage decolonial theory and practice as an alternative to the prominent thinking of the West as illuminated in liberalism and Marxism. As such, Hira’s Decolonizing the Mind serves as a major opposition to the massive production of Westernised knowledge. By methodically considering Hira’s alternative narrative to dominant Western thoughts and practices, this review will serve as a critical appraisal of his decolonial theory and practice. Thus, Hira’s Decolonizing the Mind is a scholarly and timely attempt at the production of knowledge and other ways of knowing.
