Authors: Asmanizar Asmanizar , Waridha Aldy , Sri Utami Filzah
Published: April 2024

Hama Spodoptera frugiperda merupakan hama invasif dan penyebaran sangat cepat sehingga saat ini wilayah serangannya pada tanaman jagung meluas di beberapa provinsi. Pengendalian dengan memanfaatkan bahan aktif tumbuhan merupakan salah satu cara untuk mengatasi masalah serangan hama ini.  Penelitian bertujuan untuk mengetahui pengaruh konsentrasi ekstrak biji Jatropha curcas terhadap larva S. frugiperda.  Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap dengan lima perlakuan konsentrasi (0,0625; 0,025; 0,25 dan 0,5%) dan kontrol serta empat ulangan. Pengujian dilakukan dengan metode racun perut dan metode racun kontak. Pengaruh perlakuan terhadap variabel yang diamati dianalisis dengan Analisa Sidik Ragam, LC50 dan LT50 sebagai racun perut dan kontak dianalisa dengan Analisis Probit. Hasil penelitian menunjukkan konsentrasi 0,5% dengan mortalitas larva secara nyata lebih tinggi dibandingkan dengan konsentrasi lainnya, baik pada pengujian racun perut maupun racun kontak dengan mortalitas masing-masing 65 dan 85% pada pengamatan 7 hari setelah aplikasi. Konsentrasi 0,25 dan 0,125% menunjukkan mortalitas yang tidak berbeda nyata (57,5% dan 52,5%) pada pengujian racun perut, sementara itu konsentrasi 0,25, 0,125 dan 0,0625% menunjukkan mortalitas yang tidak berbeda nyata (60, 60 dan 55%) pada pengujian racun kontak. Ekstrak biji J. curcas lebih toksik sebagai racun kontak (LC50=0,21%; LT50=4,01 hari) dibandingkan sebagai racun perut (LC50=0,34%; LT50=6,16 hari). Pupa dan imago yang terbentuk lebih banyak pada pengujian racun perut (35 dan 22,5%) dibandingkan dengan racun kontak (15 dan 2,5%). Ekstrak biji J. curcas mempunyai potensi untuk mengendalikan hama S. frugiperda. Pengujian tingkat lapangan diperlukan untuk melihat efektivitas di areal pertanaman jagung.

Surface-enhanced raman spectroscopy with machine learning in non-invasive detection of dengue-NS1 fingerprint
Authors: Mohd Radzol Afaf Rozan , Khuan Y Lee , Peng Shyan Wong , Looi Irene , Mansor Wahidah
Published: April 2024

The surface-enhanced Raman spectroscopy (SERS) method exploits the plasmonic effect of nano-sized metallic materials to intensify the Raman scattering of the monochromatic light of analyte molecules. This promotes the sensitivity and specificity of the Raman spectroscopy analysis method. This study integrated SERS with machine learning (ML) to detect dengue fever, a disease infecting more than 40% of the world’s population. Non-structural protein 1 (NS1), detected in the sera of infected dengue patients during the early infection stage, is currently recognised as a biomarker for the early diagnosis of DF. However, no attempts have been made to detect NS1 in the salivary Raman spectra. Given this situation, this study delves into the potential of SERS as an early, non-invasive DF detection technique using salivary NS1. The SERS spectra of saliva samples (n=289) were collected and subsequently classified as positive and negative for DF, using principal component analysis (PCA) integrated with support vector machine (SVM) models. The PCA-SVM model's performance was benchmarked against two clinical diagnostic NS1-enzyme-linked immunosorbent assay (ELISA) tests recommended by the World Health Organization (WHO). The PCA-SVM model outperformed both tests regarding radial basis function kernel (RBF) and cumulative percent variance (CPV; 83.22% accuracy, 88.27% sensitivity, 78.13% specificity). It is encouraging that the sensitivity level of the PCA-SVM model is above the benchmark set by the saliva-based NS1-ELISA tests proposed by the WHO, demonstrating the potential of SERS for the non-invasive detection of DF.
Underlying Processes in the Norwegian Universal Preventive Program for Social Anxiety

Published: April 2024

Few prevention investigations undergo testing of mechanistic hypotheses. To date, no published study has reported the processes underlying the effectiveness of a prevention program aimed at reducing social anxiety in a population-based sample of preadolescents. A parallel multiple mediator model was used to examine the mediation of outcomes from the Norwegian Universal Prevention Program for Social Anxiety (NUPP-SA) by five intermediary variables that well approximate established DSM-5 social anxiety disorder diagnostic criteria. The NUPP-SA works differently for preadolescents with subsyndromal versus syndromal social anxiety. Among the former, the NUPP-SA intervention works via public performance, avoidance, physical/cognitive, and assertiveness factors. For the latter, the NUPP-SA works via the public performance factor. The intervention did not work for either group via the social encounter factor. Universal prevention programs are essential for reducing the impacts of chronic disorders at the individual, institutional, and societal levels. Introducing a universal prevention program in school settings requires validation, including these results demonstrating that the NUPP-SA affects both those with syndromal and subsyndromal social anxiety symptoms via public performance. These results support the notion that many children with subsyndromal social anxiety disorder can be impacted with adequate intervention, which is both feasible and, given the widespread problem with public speaking, suggests a target for universal implementation.

It has been suggested by various cognitive behaviour theorists that the perceptual and cognitive characteristics of the preoperational cognitive stage, defined by Piaget as the second stage of cognitive development, manifest themselves in chronic depression and various personality disorders. Although individuals have a formal level of functioning in their work life, they may experience regression to the preoperational domain due to an event in the interpersonal domain. In this study, the relationships between preoperational thinking and psychiatric symptoms (depression and anxiety) and personality traits were analysed. The sample consisted of 61 patients and 102 healthy individuals (104 women, 55 men). Sociodemographic form, Personality Belief Questionnaire-Short Form (PBQ-SF), The Luebeck Preoperational Thinking Recording Scale (LQPT) and Patient Health Questionnaire -9 (PHQ-9) were applied to the participants.
The study results revealed a diverse predictive role of LQPT scores across different personality traits. LQPT is highly predictive for traits like Histrionic and Dependent, moderately predictive for Borderline, Obsessive-Compulsive, and Antisocial, less predictive for Paranoid, Passive-Aggressive, and Narcissistic, and not predictive for schizoid personality traits. The results of this study also showed a significant relationship between an increase in general psychiatric symptoms (depression and anxiety) and an increase in preoperational thinking levels. It was also found that preoperational thinking was significantly higher in patients with psychiatric disorders (GAD, OCD, depression, panic disorder). These findings support the results of previous research that provide a new interpretation of Piaget's work on the preoperational stage in the context of personality and psychiatric symptoms in adults.

Published: April 2024

Surra caused by Trypanosoma evansi is a disease that appears every year in East Sumba district and causes quite large losses. This study aims to determine the seroprevalence and risk factors that influence the incidence of surra in East Sumba district using a total of 226 horse and cattle blood samples obtained from seven sub-districts and the examination was carried out using the serological method, namely the card agglutination test (CATT/ T. evansi). A semi-structured questionnaire was used to collect data on risk factors associated with surra. The results showed that the seroprevalence of surra in horses and cattle was 32,30%. Seroprevalence in horses was 32,85% and in cattle was 26,31%. The risk factor of presence of flies and maintenance methods statistically have a significant effect on the incidence of surra, while age, gender, the presence of other animals and the farmer's knowledge about surra do not statistically have a significant effect on the incidence of surra. Thus, it is necessary to carry out surra surveillance in cattle which are the reservoirs and preventive measures are needed, especially those related to risk factors wich statistically have a significant effect on the incidence of surra. Apart from that, it is necessary to carry out further research on other risk factors related to the incidence of surra and research in different season periods.

Published: April 2024

The poultry industry in Indonesia is still experiencing problems, especially in terms of disease attacks, one of which is Newcastle Disease (ND). ND is caused by Avian Paramyxovirus type-1 (APMV-1) virus and is an infectious and also acute disease in Indonesia. ND management has so far been carried out by vaccination and improved husbandry management. ND vaccination can use active vaccines, inactive vaccines or combination vaccines. Despite vaccination, ND is still frequently reported.  The aim of this study was to determine the safety of Newcastle Disease (ND) Genotype VII vaccine based on post-vaccination virus shedding. Shedding viruses leave the body of poultry through excretion, especially feces, which can cause environmental pollution. The samples used were 10 cloacal swab samples of laying hens taken for five periods and isolation of embryonated chicken eggs. The inoculated liquid on embryonated chicken eggs was harvested and HA test was conducted to check the shedding of ND vaccine virus. The results showed no shedding of the vaccine virus characterized by negative results in the HA test. These negative results indicate that the inactivated ND Genotype VII vaccine is safe for the environment, however farmers need to implement biosecurity to prevent the entry of ND into the farm.

Animal welfare is everything related to the physical and mental state of animals in accordance with the standard of natural animal behaviour that needs to be implemented to protect animals from inappropriate treatment by humans. This study aims to determine the description of the application of animal welfare on pig farms in the highlands and lowlands in Gianyar Regency. The research design was observational by interviewing 20 farmers in each of Puhu Village (highland) and Pering Village (lowland) conducted in January 2024 using an integrated questionnaire. The data obtained were then analysed descriptively qualitatively and presented in tabular form. The Mann Whitney test was conducted to determine the difference between the application of animal welfare standards in highland and lowland areas. The results showed that the application of animal welfare on pig farms in Gianyar was in the very good category 30%, good category 65%, and fair category 5%. While the results of the comparison test found a difference in the fulfilment of the principle of free expression of the natural behaviour of pigs. It can be concluded there was a difference between the application of animal welfare standards on pig farms in the highlands and lowlands. It is recommended that pig farmers in Pering village provide enrichment facilities for pigs to express their natural behaviour.

Shells That Have Been Polluted by Lead Around Youtefa Bay in Jayapura City Have Potential Risk of Non-Carcinogenic
Authors: Hasmi
Published: April 2024

Objective: This study aims to analyze how much of a health risk caused by lead exposure in shellfish can affect the health of humans or communities living around this location.
 
Method: This study is an observational study with risk analysis or Hazard Quotient. Samples have been collected through purposive sampling methods, using a cross-sectional study design.
 
Results and conclusions: The results showed that the concentration of lead in shellfish concentrations from 12 stations had an average value of 0.57 mg/kg and was classified as polluted because it was above the limit of the number of Indonesian National Standard 7387 of 2009 because the polluted standard was more than 0.3 mg/kg. Of the 75 respondents, the study found 33 respondents (44%) who had an RQ (risk quotient) of more than 1 indicating that they were vulnerable to lead contamination. It showed that the average RQ value of clams among the 75 respondents was 2.42. An average RQ of more than one suggests that people living near Youtefa Bay are at risk for developing the effects of lead exposure from polluted shellfish.
 
Implications of the study: This study in addition to measuring the concentration of Lead in shellfish also calculated the Risk Quotient of people who consumed shellfish with Hazard Quotient analysis.
 
Originality/value: Based on the calculation of the formula, the average value of RQ (2.42) is very high because RQ is above 1; therefore, this number (RQ) must be controlled. Researchers recommend that residents living near Youtefa Bay should be cautious of lead exposure by reducing total shellfish intake and reducing prolonged lead exposure.

Published: April 2024

Objective: This research aimed to analyze the giant salvina (Salvinia molesta D.Mitch) and water lettuce (Pistia stratiotes L.) potential, collected in the eutrophic environment for biodiesel production.
 
Theoretical framework: Macrophytes can cause environmental and economic damage in eutrophic environments due to excessive growth, being necessary for removal. In this sense, the destination of this biomass can be challenging.
 
Method: The moisture and lipid content of the macrophytes was evaluated and the yield of biodiesel produced via in situ transesterification by methyl and ethyl route for dry biomass was compared.
 
Results and conclusion: S. molesta showed the highest moisture content, with both macrophytes showing a significant difference (p < 0.05) between them and between the analyzed parts. P. stratiotes showed a lipid content significantly higher (p < 0.05). The yield of the biodiesel produced via in situ transesterification, by the ethylic route was higher (p < 0.05) for both biomasses, with P. stratiotes obtaining the best yield and S. molesta presenting the best use for the determined lipid content.
 
Implications of the research: P. stratiotes presented the best results for the production of biodiesel in the analyzed parameters, being a possible destination for this type of biomass.
 
Originality/value: The disposal of macrophytes from eutrophication means for biodiesel production is a new eco-friendly alternative for macrophyte infestations.

Authors: Suliman Wesam , Charles Tendai , Sawalha Omaima
Published: April 2024

Objective: This research investigates the influence of integrative and instrumental motivations on English Language Learning (ELL) among students in private educational institutions within the United Arab Emirates (UAE). It aims to discern which type of motivation—integrative or instrumental—exerts a greater impact on second language acquisition.
 
Method: A quantitative research methodology was employed, utilizing a 44-item questionnaire adapted from the Motivation Test Battery. The study sample consisted of 101 English as a Second Language (ESL) students. Statistical tools such as regression analysis and correlation coefficients were used to analyse the data, providing insights into the relationships between motivational types and language acquisition success.
 
Results and Discussion: The study revealed a positive correlation between both integrative and instrumental motivations and ELL. Notably, integrative motivation had a more substantial influence on the ESL outcomes compared to instrumental motivation. These results underline the complexity of motivational impacts on language learning, with integrative motivation playing a pivotal role.
 
Research Implications: The findings suggest that educational strategies that enhance integrative motivation could be more effective in promoting successful language learning. This could involve fostering a deeper connection with the language community and culture, thereby enriching the educational experience and outcomes for ESL learners.
 
Originality/Value: This study contributes to the existing body of knowledge by focusing on the comparative impacts of integrative and instrumental motivations in the context of the UAE—a region where such studies are seldom conducted. The insights regarding the predominant influence of integrative motivation add a valuable dimension to the global discourse on second language acquisition, especially in multilingual and multicultural learning environments.

Objective: The purpose of the research is to show a specific process to perform the cost/benefit analysis in the social evaluation of public investment projects in the education sector, applying the net present value (NPV) and internal rate of return (IRR) profitability indicators, taking into account that the approach of the National System of Multiannual Programming and Investment Management (Invierte.pe) applies a different methodology as the cost/efficiency analysis, where it uses criteria such as the Present Value of Costs (PVC) and the Cost Efficiency Indicator (CEI).
 
Theoretical framework: In order to present our proposal, we used as a theoretical framework, mainly the directives, instructions, procedures, and methodological guides proposed by the Ministry of Economy and Finance of Peru, which can be improved by considering the results of investment in education.
 
Method: The research proposes a technique to evaluate investment projects in the education sector through the cost/benefit methodology instead of the cost/effectiveness methodology. Within the materials and methods, an education sector investment project approved by Invierte.pe was used, and we added cost/benefit analysis to estimate the profitability indicators NPV and IRR to carry out the social evaluation of the project.
 
Results: The results show that the education project has a net present value of S/. 794,874.30 at social prices, and an internal rate of social return of 9.56%. Finishing the research, it can be concluded based on the results obtained that it is possible to incorporate the cost/benefit methodology in the formulation and evaluation of standard, simplified technical sheets and studies at the profile level of public investment projects in the education sector.
 
Conclusions: It can be concluded that it is feasible the social evaluation of investment projects in the educational sector of the Peruvian state, through the cost/benefit methodology in the region and the country, by means of the profitability indicators NPV and IRR, obtaining a higher internal rate of return.

Published: April 2024

Objective: This study aimed to verify the rate of occurrence of frontal intermittent rhythmic delta activity (FIRDA) in electroencephalograms (EEGs) of adult patients in the intensive care unit (ICU) and its correlation with either neurological or non-neurological etiologies or prognoses.
Methods: A retrospective review was performed on 239 EEGs with analysis of their neuroimages and clinical data from an ICU at King Fahad Hospital, Hufof from November 2021 to October 2022. A literature review was also conducted using the PUBMED database. The search scope was covered by the keyword "FIRDA" and was limited to English-language articles.
Results: A total of 239 EEGs were conducted in the ICU, 19 (7.9%) had either electrographic or clinical seizures with or without slowing and/or interictal epileptiform discharges, 6 (2.5%) EEGs had FIRDA, and the rest of the EEGs (80.5%) had only generalized slow or rarely other EEG patterns which were noted in coma. Toxic metabolic disturbances and sepsis were the acute diagnoses of all the observed cases. There were no clinical seizures in the patients who had FIRDA and no history of epilepsy. There was no significant association between FIRDA and the seizure occurrence where the p-value was 1 (Confidence interval—0, 10.28).
Conclusion: This study provides valuable insights into the incidence, clinical characteristics, and outcomes of FIRDA in critically ill patients admitted to the ICU. While FIRDA remains a relatively uncommon finding, its association with toxic-metabolic disturbances and sepsis underscores the importance of comprehensive neurological monitoring in critically ill patients.
el Whispering Clouds, Echoing Mountains: A Cross-Cultural Analysis of Gonzalo Ariza’s Lyrical Landscapes
Authors: Carbonell Prospero
Published: April 2024

This essay reevaluates the art of Gonzalo Ariza, a twentieth-century Colombian painter renowned for landscapes that merge Eastern and Western traditions. Challenging simplistic categorizations of his oeuvre as an “appropriated Japanese style,” my research argues that Ariza’s vision of landscape transformed into a contemplative attitude towards local Andean highlands after his return from Japan in 1938. It contextualizes the challenges Ariza faced when drawing inspiration from East Asian art amidst mid-twentieth-century modernist currents and political circumstances, shedding light on the critical narratives that marginalized his work and unraveling the complexities of Colombian modernism within a global art discourse. Building upon Warburg's concept of dynamograms to describe “pathos formula” in landscapes, this study argues that Ariza’s work transcends cultural boundaries, which links both traditions through the subtle emotions evoked by cloud-shrouded mountains, eliciting a universal appreciation for nature’s mystical splendor. Through cross-cultural comparison and an ecocritical lens, my essay delves into the interplay of transcultural exchange, nationalist identity, andrepresentations of nature in Ariza’s artworks, revealing his nostalgic proto-environmental consciousness. In doing so, it raises raising questions about the transformative power of landscape art to reflect and influence societal values and perspectives on nature within contemporary dialogues on environmental stewardship and the negotiation of cultural identity through art.

Lesser galangal rhizomes are well known for their anti-inflammatory, anti-microbial and anti-oxidant properties. The aim of the present study was to assess the variability in morphological and biochemical characters of lesser galangal, Alpinia calcarata accessions collected from various South Indian states. The results revealed that accession IC373608 was significantly superior with respect to yield contributing traits including the rhizome length, width, fresh yield and dry recovery (6.02 cm, 2.40 cm, 14.63 g tiller-1 and 33.26% respectively) among the eighteen accessions studied. The biochemical analysis of rhizomes revealed that the maximum volatile oil and oleoresin content were found in the accession IC468880 (0.75%) and IC373608 (34.20%) respectively. The highest values for total phenols, total flavonoids and starch were observed in the accessions IC373608 (115.25 mg GAE.g-1), IC582825 (55.65 mg QE. g-1) and IC210656 (44.05 mg. g-1) respectively. The accession IC550112 (7.90%) recorded the lowest crude fibre content, whereas the highest total terpenoid content was noticed in accession IC210421 (20.25%). The GCMSMS profiling of volatile oil of A. calcarata rhizome showed the presence of 28 compounds in it. Considering all economically important characters, accessions IC373608, IC582825 and IC210421 were found to be superior and can be utilized in future crop improvement programmes.

An experiment on pepper based mixed cropping systems involving tuber intercrops was carried out at Pepper Research Station (Kerala Agricultural University), Panniyur, Kannur during 2013-14 to 2022-23. Five different black pepper based mixed cropping systems which accommodated five different tropical tuber crops were experimented. The data pertaining to 2020-21, 2021-22 and 2022-23 were separately recorded and the pooled mean worked out for individual crop yields as well as equivalent yields and economics of cultivation of the different systems. The pooled equivalent yield for black pepper + greater yam and black pepper + elephant foot yam mixed cropping systems were recorded in terms of base crop black pepper as 1239.28 and 1214.25 kg ha-1 respectively, significantly superior to all other mixed cropping systems. The equivalent yield recorded for black pepper sole cropping was 561.73 kg ha-1 only. The pooled data revealed higher profitability for black pepper + greater yam mixed cropping system with gross returns, net returns and B:C ratio of Rs. 619637 ha-1, Rs.440043 ha-1 and 3.45 respectively. For black pepper + elephant foot yam   system, the respective values were Rs. 607126 ha-1, Rs. 440043 ha-1 and 3.57. The soil properties were also favourably maintained under mixed cropping as that in sole cropping of black pepper as indicated by soil nutrient analysis conducted at the end of the field experiment.

Published: April 2024

A comprehensive survey was conducted in the nutmeg-growing region of Kerala state to locate superior clones of nutmeg, by employing Participatory Varietal Selection (PVS) method. Twenty-nine superior accessions were identified through mother tree characterization for four consecutive years. The characterized clones were female and produced fruits ranging from 628 to 2250 tree-1 year-1, dry nut weight varied from 3.27 g to 15.37 g, and assorted dry mace weight varied from 0.35 g to 4.80 g. Genetic variability analysis revealed high heritability with high genetic advance as per se mean (dry mace weight 76.30%, dry kernel weight 71.37% and the number of fruits tree-1 73.24%) which signifies the advantage of simple selection method of breeding. Based on the economic importance of yield contributing characteristics, five superior clones out of twenty-nine mother trees evaluated have been released as KAU- farmer’s varieties. All the superior trees identified based on yield traits had appreciable quantities of volatile oil (1.63-12.25% in nut; 3.31-16.97% in mace), oleoresin (17.60-41.77% in nut; 13.00-30.50% in mace) and fixed oil (22.45-40.70% in nut) in their nuts and maces as well as myristicin, elemicin, safrole and sabinene in the volatile oils. The characteristic features of mother trees and released varieties are discussed in this paper, and further, these varieties are recommended for commercial cultivation under tropical moist, humid climate conditions.
Identification of drought tolerant turmeric (Curcuma longa L.) genotypes with sustainable yield
Authors: Nazmin Banu C V , Krishnamurthy K S
Published: April 2024

Turmeric (Curcuma longa L.) (Zingiberaceae), is native to south west India. Water stress is the most common adverse environmental condition which severely affects crop productivity. Here we have analysed morphology, stomatal density, relative water content, electrolyte leakage, epicuticular wax content and rhizome yield of 50 elite turmeric genotypes for identification of genotypes with differential response (tolerance and susceptibility) to water stress. Results showed that water stress during rhizome development stage (90-120 days after planting) significantly decreased the leaf relative water content and increased membrane permeability. Epicuticular wax content varied significantly among the genotypes. Genotypes with lower leaf area, higher relative water content, lesser electrolyte leakage, higher wax content and fewer stomata than other genotypes were shortlisted as tolerant. From among these shortlisted ones, four tolerant genotypes (IISR Pragati, SL 5, Suguna, and Suvarna) with higher yield, along with two susceptible genotypes (IISR Alleppey Supreme and IISR Kedaram), were further evaluated in field conditions. The results indicated that, in terms of yield and physiological parameters, the tolerant genotypes significantly outperformed the susceptible ones, showcasing superior drought tolerance traits. These genotypes with contrasting characters can be used for further studies to elucidate the mechanism of drought tolerance.
