Published: August 2024

On the Brazilian coast, the commercialization of Anomalocardia flexuosa is based on fishing in natural banks, but its stocks have been declining. As an alternative to this limitation, laboratory production is promising for plans of repopulation and cultivation of A. flexuosa. Aiming to develop techniques for this purpose, the current study evaluated the influence of temperature and salinity on the rearing of A. flexuosa larvae. Two experiments were conducted: (1) the effect of different salinities (25, 30, and 35 g L- 1) on survival and growth in the larval stage of A. flexuosa, lasting seven days; and (2) the effect of temperature (22 and 26 ºC) on larval growth and survival, lasting ten days. In both experiments, the D larvae were stored in experimental units (2 L) with a density of 10 larvae mL-1. At salinities of 25 and 30 g L- 1 there were greater survival rates. When analyzing the final length and the daily growth rate, the higher values were observed at salinity of 25 g L- 1, 126.08 ± 1.45 µm and 8.33±0.20 µm day-1, respectively. Regarding temperature, 26 ºC showed better values both for survival (62.25 ± 3.48%) and larval development (210.19 ± 0.56 µm). Thus, to optimize productivity, it is recommended to maintain salinity between 25–30 g L- 1 and a temperature of 26 °C.

Published: August 2024

Sweeteners are food additives consumed worldwide, especially by individuals with restrictive diets. This study evaluated the cytotoxic and genotoxic effects of sweeteners widely sold in Brazil through a bioassay with Allium cepa. Onion bulbs were exposed to different concentrations of sweeteners, and their root cells were stained with acetic carmine and analyzed under an optical microscope. Distilled water was used as a negative control, and glyphosate as a positive control. The results demonstrated that the mitotic index (MI) and the chromosome aberration index (CAI) of the three sweeteners tested did not differ significantly from the negative control, indicating that they are not toxic or mutagenic additives. This result is positive for consumers of these products, especially those who need to replace sugar due to dietary restrictions. However, they should be consumed with caution.

Published: August 2024

Fauna conservation in anthropic ecosystems is crucial. This study aimed to assess the role of forest fragments in protecting bird communities within the urban matrix of Blumenau, state of Santa Catarina, Brazil. Bird species were identified using visual and auditory methods across five forest remnants from January 2016 to December 2019. Fieldwork began in the early morning and covered both the interior and edges of the areas. The relationship between species richness and land use within the forest fragments and adjacent matrices was investigated to support management actions for expanding urban landscapes. These actions are necessary as habitats and corridors may be eliminated, leading to reduced landscape connectivity. The results indicate an interaction between fragment size and land use, which contributes to the formation of environmental mosaics in the urban landscape. These mosaics may influence bird species richness and composition. Effective public management of legally unprotected forest remnants, regardless of size, along with permanent preservation areas (e.g., riparian forests and urban green spaces) and conservation units, may strengthen a network of green areas for protecting and conserving Atlantic Forest bird species in urban environments.

Estudos voltados ao comportamento das artérias coronárias foram desenvolvidos em várias espécies, de modo a elucidar a variabilidade da sua distribuição e suas correlações morfofuncionais, como os tipos de irrigação e possíveis riscos de infarto do órgão. Com o aumento da frequência de felinos domésticos na rotina clínica de pequenos animais forçando a especialização de profissionais capazes de conhecer e considerar as diferenças morfológicas para o diagnóstico clínico mais assertivo, este estudo teve como objetivo identificar a origem e distribuição das artérias coronárias dos gatos domésticos. Utilizou-se vinte e nove espécimes de gatos domésticos, quinze fêmeas e quatorze machos, fixados com solução de formaldeído a 10%, injetados com látex líquido corado com corante sintético e alocados em solução formaldeído a 10% por no mínimo 7 dias, sendo posteriormente dissecados. O método usado para determinar o padrão de dominância coronariana foi baseado na origem do ramo interventricular subsinuoso, sendo capaz de ser definido como uma dominância direita, esquerda ou equilibrada. O padrão de dominância nos gatos domésticos foi determinado como equilibrada (69%) e esquerda (31%), contrariando a literatura vigente para o ensino de anatomia animal, podendo-se observar ainda presença de anastomose entre as coronárias e ponte miocárdica em alguns indivíduos. Os resultados encontrados no presente estudo reforçam a existência das particularidades interespecíficas em carnívoros domésticos. Neste contexto, a descrição das artérias coronárias de gatos domésticos contribui para a anatomia animal aplicada, uma vez que o entendimento acerca dos vasos que nutrem o miocárdio permite análises anatomopatológicas mais assertivas para a espécie.

Aim of this study is to investigate the safety, efficacy and impact on Health-Related Quality of Life (HRQoL) of Vertebroplasty (VP) and Kyphoplasty (KP) in the management of Osteoporotic Vertebral Compression Fractures (OVCFs) in elderly individuals. VP and KP represent Minimally Invasive Vertebral Augmentation (MIVA) procedures that are increasingly implemented for surgical treatment of OVCFs in recent years. These interventions have been associated with minimal traumatization and intraoperative hemorrhage, considerable analgesic effect and rapid postoperative recovery. Seventy-seven (77) consecutive individuals with OVCFs were subjected to VP/KP and recruited in this prospectively designed non-randomized study. Clinical evaluation was performed preoperatively and postoperatively at particular chronic intervals at 1, 6 weeks and at 3, 6, 12 months and 2 years. Assessment was conducted via the standardized Visual Analogue Scale (VAS) and Short-Form 36 (SF-36) Medical Health Survey Questionnaire for pain and HRQoL, respectively. No perioperative complications were observed. All studied indices were demonstrated to present a statistically significant amelioration following overall analysis. Pain intensity measured by the VAS score was depicted to be significantly reduced during the first 3 months, but continuous improvement of all indices of SF-36 and VAS was demonstrated to reach a plateau at 6 months, featuring no further clinical improvement.VP and KP represent safe and efficient options for interventional treatment of OVCFs in elderly and oldest-old patients, improving self-reported symptoms of pain as well as overall HRQoL.

Published: August 2024

Recurrent Pregnancy Loss (RPL) is diagnosed in 3% of all patients of reproductive age and is of high interest to reproductive medicine specialists. Immunological predispositions are among the crucial risk factors for RPL development in female patients suffering from RPL. Therefore, the purpose of this work is to investigate the role and effectiveness of individualised immunological treatment approaches by analysing several clinical cases with diagnosed pregnancy loss and the results of tailored immunological therapies. Based on 25 years of clinical experience and scientific research the paper analysed the relationship between Human Leukocyte Antigens (HLA) tissue compatibility and ABO blood group system incompatibility in immunological pregnancy failure. The connection of these factors was shown in 2 clinical cases suffering from RPL who agreed to participate in research. Research was performed at Nakhchivan Birth Center and Nakhchivan State University. The results of the study provided evidence based on these cases of RPL that ended with successful childbirth after the suggested genetic assessment and immunological treatment. Individual treatment of immunological pregnancy failure with HLA and ABO blood group incompatibilities showed more effective outcomes if compared to previous schemes of treatment. HLA compatibility in loci 3 combined with affinity on the ABO system strongly demanded immunological therapy prescription for successful implantation of the blastocyst. The outcomes obtained from the study can be implemented in obstetrics and gynecology for the improvement of clinical cases suffering from RPL.

Published: August 2024

Coronary heart disease, the most prevalent non-communicable disease, poses both physical and psychological challenges, including anxiety and depression. Addressing these issues requires a holistic approach that integrates biological, psychological, social, and spiritual dimensions. Spiritual care interventions can alleviate psychological distress and enhance patient satisfaction in nursing care. This study explored the impact of combining spiritual care with murottal auditory therapy to reduce anxiety and depression in patients with coronary heart disease. In this quasi-experimental study, 110 participants were divided into intervention and control groups, each with 55 participants selected based on specific criteria. Anxiety and depression levels were assessed using the validated Depression Anxiety Stress Scale (DASS). The intervention group received daily murottal therapy sessions lasting 15 to 20 minutes for three days at Siti Khadijah Islamic Hospital in Palembang from March to July 2023. Pre-test and post-test assessments were conducted. The results indicated that a significant proportion of patients in the intervention group experienced mild anxiety (52.7%) and reduced depression (65.5%) after murottal therapy. Significant differences in anxiety and depression levels were observed between the intervention and control groups, with p-values of 0.000 for both. murottal auditory therapy, mainly using Surah Ar-Rahman, effectively reduces anxiety and depression in patients with coronary heart disease, offering a promising complementary treatment approach.
The Ogoni Amanikpo secret society: Towards the search for secret knowledge, powers, and esoteric tradition
Authors: Deezia, Burabari Sunday, M.A., Ph.D. candidate
Published: August 2024

Human quest for esoteric knowledge of the transcendental and mundane worlds, as well as the struggle towards acquiring them through membership in secret societies has become a worldwide phenomenon. The Amanikpo secret society in Nigeria, being one of the most influential cults within the Ogoni socio-religious milieu, reenacts both political and cosmological order in Ogoni communities. However, in recent years, those noble ideas of Amanikpo have not only been misinterpreted by the emerging trends of other secret societies, but threatened by modernization and its agents. Premised on the above, this paper examines the religious-philosophical foundation, and functions of Amanikpo in the Ogoni traditional society. Using the ethnographic method, the study discovers that despite their cryptic activities, Amanikpo had (and possibly still has) a significance beyond mere entertainment, as its relevance in indigenous education, spiritual development and the preservation of Ogoni spiritual and cultural values still holds sway.

Published: August 2024

This study is a historical investigation into the contribution of traditional medicine in proffering healing solutions among the Dagomba people of Northern Ghana. The discussion of the paper is centered on the healing occupations such as traditional bonesetters, traditional birth attendants, diviners and the nature of their knowledge, practice, and their relationship with the formal health sector practitioners. Significantly, the study paid particular attention to the collaborative work between traditional healers and formal sector doctors in a rapidly changing socio-medical systems in coming up with a treatment plan and cure among the Dagomba. The study employed a qualitative research approach which dwelled on both primary and secondary sources to respond to the questions posed in the study. A careful analysis of primary and secondary data revealed that indigenous medicine has been the dominant tool the Dagomba people have utilized in proffering healing solutions to their primary health care needs since time immemorial. The study concludes among other things that collaborations should be encouraged between universities or training institutions, the ministry of health and the relevant international actors such as the World Health Organization to appraise and further roll out disciplines on indigenous knowledge and medicine, and to provide perspectives on health, illnesses and cultural orientations about health that are more useful in contemporary times within the local context.
Grand Ethiopian Renaissance Dam Project Controversies: Understanding the role of worldviews and nexus
Authors: Gashaw Ayferam Endaylalu, Ph.D.  , Yacob Arsano, Ph.D.
Published: August 2024

This paper examines the complex interplay of worldviews, siloed thinking, and the 'nexus approach' in shaping the controversy on Grand Ethiopian Renaissance Dam (GERD) project. Using a worldview-nexus framework and data from 38 key informants, government documents, and secondary sources, the study identifies Egypt's water security-centered worldview and Ethiopia's development-centered policy as key drivers of conflict. Sudan, meanwhile, navigates a middle-ground position shaped by its unique hydrological and historical context. The study also reveals that Ethiopian and Egyptian worldviews illustrate mutually exclusive thinking, neglecting the interconnectedness of water, energy, food, and environmental security across sectors and borders. In both countries' worldviews, the GERD is perceived from an existentialism and securitization view which contributes to the prevailed zero-sum game politics. Furthermore, Ethiopia's development-centered worldview has also transformed the traditional narratives around the Abbay (Blue Nile) River within Ethiopia. Conversely, Egypt's water security-centered worldview reinforces Egyptian traditional views linking the Nile to its national identity. The study suggests that adopting a nexus approach to water resources development can help reconcile the conflicting worldviews and resolution of the conflict over the GERD.

Published: August 2024

Cowpea beetle, Callosobruchus maculatus, is a major pest of stored cowpea. Farmers use mostly synthetic insecticides to control the pest in store, although biopesticides such as neem oil have been proven to be a sustainable alternative. The objective of this study was to determine the effective and feasible rates to enhance cost-effectiveness of neem oil in the management of C. maculatus in stored cowpea grains. A laboratory experiment was conducted, in which sterilised healthy cowpea grains (50 g each) were treated with neem oil at 0, 0.5, 0.75, 1 ml and 0.05 g ACTELLIC Gold Dust® (16 g kg-1 Pirimiphos methyl + 3.6 g kg-1 Thiamethoxam). The experiment was laid out in a completely randomised design, with four replications. Results revealed that adult female C. maculatus laid eggs on all the treated cowpea grains, except those treated with 1.0 ml of neem oil. However, no adult emergence and damaged grains were recorded from grains treated with 0.50, 0.75 and 1.0 ml of neem oil. This study has shown that cowpea grains treated with 0.50, 0.75 and 1.0 ml of neem oil outperformed those treated with insecticide actellic dust. Among the rates of neem oil assessed, there was no significant difference between their effect on the management of C. maculatus. Thus, 0.50 ml of neem oil per 50 g of cowpea grains is the most cost-effective rate for the management of C. maculatus in stored cowpea grains.

Published: August 2024

The sweetpotato (Ipomoea batatas (L) Lam) seed system in Uganda is transiting from an informal to a formal setting, by integrating the use of certified sweetpotato seed (CSS) in the production system. Use of CSS enhances productivity by controlling the spread of the sweetpotato virus disease (SPVD) and seed degeneration. However, owing to the limited understanding of product and service quality attributes by farmers, the sustained use of CSS has remained dismal. The objective of this study was to investigate the contribution of farmer socioeconomic characteristics; product and service quality attributes to sustained use of CSS in Uganda. A total of 289 sweetpotato farmers from Central (Mpigi district) and Northern (Omoro district) Uganda, representing low and high SPVD prevalence zones, respectively, were interviewed to obtain information on product attributes (acceptability, accessibility, affordability and awareness) and service attributes (reliability, tangibility, assurance, responsiveness and empathy). Data were subjected to a Double Hurdle analysis. Results revealed that users of CSS scored more for product and service quality attributes, than their non-user counterparts. There was a highly positive correlation between use of CSS and education level in central; but a modestly positive in northern Uganda. Reliability (b = 0.289, 12.612) positively drove the use and extent of use of CSS; while for tangibility (b = -0.302, -11.742), the converse was true. Also, acceptability (b = 0.469, 22.048) increased the use and extent of use of CSS; yet accessibility increased only the use in both locations (b = 0.268). Thus, efforts to scale-out CSS use in the study areas should focus more on affordability, awareness, assurance and empathy based on location; putting into consideration education level and group membership differences.
Farmers’ perception of weed infestation and management in some Agrarian Communities of Southern nigeria
Authors: Aluko O.A. , Adelakun O.J.
Published: August 2024

Weed infestation is detrimental to crop yield and quality, limits farm size, increases the cost of production, reduces profit, and impairs  farmers’ livelihood. This study was conducted to assess the weed infestation status based on the farmers’ perspective, the control  measures adopted, and the potential weed problem in some agrarian communities in Derived Savanna agroecology. A Structured  questionnaire was administered to one hundred and ten (110) farmers. Data were analyzed using the Descriptive analysis method. Most  (75.5%) of the farmers were male and almost half (43.6%) had the mean farming experience of 22.46±9.99, while 46.4 percent had within  11-15 years of formal education. However, the mean age was 49.93±10.70 years. Most farmers (90%) had the lowest income level (N10000  – N50000). Farmers (25% – 50%) identified Cyperus rotundus, Imperata cylindrica, Tridax procumbens, Commelina bengalensis,  Emilia sonchifolia, Axonopus compressus, Tithonia diversifolia, Pennisetum purpureum, and Euphorbia heterophylla as problematic  weeds. Farmers understood and adopted manual weeding (100 %), and chemical (98.2 %) weed control methods. However, few farmers  (2.7%) knew or adopted the concept of integrated weed management and biological weed control (3.6 %) methods for weed  management. The farmers’ perception of weed infestation might be useful in early warning systems for preventing and managing noxious weeds and ensuring sustainable crop production. The training of farmers on the principles of integrated weed management  (IWM) for effective weed control, improved crop yield, and livelihood is essential.

This study was aimed at evaluating the acceptance of genome-edited food in Nigeria. Utilizing the Federal Capital Territory (FCT), Abuja as  a case study, this study adopted a descriptive research design. Data was collected via a likert-scale based questionnaire administered  to a sample population of 400 respondents to collect data on level of awareness on genome-edited food, factors influencing the attitude  and perception, as well as strategies for enhancing consumer education and communication concerning genome edited food. Findings of  this study indicate that respondents were familiar with genome-edited food to a little extent (30.1%) while a total of 48.5% were not  aware of the availability of genome-edited food products currently available in the market. However, 36.8% of the respondents indicated  willingness to consume genome-edited food once benefits are understood. Also, respondents indicated concerns about the safety of  genome-edited foods to a very great extent (35.3%), while to a moderate extent (27.4%) respondents indicated that media report  influenced their perception of genome-edited food to a moderate extent. Respondent also indicated that the reported current  educational initiatives in informing the public about genome-edited food was not effective at all and therefore recommended that public  discussions and forums about genome-edited food must be put in place by the government through the National Biosafety Management  Agency.

Authors: Msacky Richard
Published: August 2024

Employee retention is crucial for enhancing organisational performance, particularly in the healthcare sector, which faces a global shortage of workers. This study examines the influence of training on the retention of human resources for health within the decentralised health system of Dodoma City, Tanzania. The research employs a mixed-methods approach to collect quantitive data from 230 human resources for health and qualitative data from key informants. Quantitative data collected through survey questionnaires were analysed using descriptive statistics and multiple linear regression. Qualitative data from interviews were analysed using content analysis to complement the quantitative findings.The study revealed  that retention among human resources for health in the decentralised system under the LGAs is high.Moreover, the findings revealed that training significantly influences employee retention, with skills acquisition, knowledge acquisition, training opportunities, and training duration all positively associated with retention rates. The findings underscore the importance of continuous professional development and training programs in retaining healthcare workers under LGAs. The study recommends that local government authorities prioritise employee training to improve retention and enhance the overall quality of healthcare services. Further research should explore additional factors influencing retention and expand the study to other regions in Tanzania for broader generalizability.

Published: August 2024

The use of onions as a natural source of medicinal compounds is on the rise globally. However, its therapeutic effectiveness is limited by several factors, including poor solubility, low bioavailability, etc. Hence, developing strategies to overcome these limitations and enhance their therapeutic potential is justified. This study therefore investigates the potential of green synthesis using a nanotechnology approach to enhance the biological properties of onion extracts. Three different onion varieties were used. The bulbs of each onion were sliced, air-dried, and separately extracted using an ethyl acetate and ethanol solvent mixture (1:1 v/v). Each extract obtained was divided into two: plain onion extract and synthesised silver nanoparticles (Ag-NPs) onion extract. This was obtained by mixing the extract with a solution of silver nitrate and heating for 5 hours at 60oC. DPPH (1,1 difenyl-2-picryl-hydrazyl) and hydrogen peroxide scavenging, total antioxidant capacity, red blood cell membrane stabilisation, protein denaturation, and heat-induced hemolysis were assayed. The results of the study showed enhanced DPPH scavenging abilities by the synthesised silver nanoparticles of onion extracts at ≤ 81.01% in comparison to the value exerted by the plain onion extracts at ≤ 75.61%. The total antioxidant capacities of the synthesised Ag-NPs ranged from 0.46±0.6 to 0.85±0.06 mg AAE/g dry extract, while the plain onion extracts ranged from 0.76±0.3 to 0.96±0.09 mg AAE/g dry extract. The synthesised Ag-NPs inhibited protein denaturation at 61.80±0.09–73.34±0.16%, compared to 42.25±0.20–55.08±0.12% by the plain onion extract. The study suggests that green synthesis using nanotechnology approaches can enhance the antioxidant and anti-inflammatory potential of onion extract, leading to improved therapeutic efficacy.

Monosodium glutamate (MSG) induces nephrotoxicity accompanied with oxidative stress at high dose (8000 mg/kg). Medicinal prospects of underutilized Telfairia occidentalis pod, TOP was suggested recently. This study investigated the in vitro antioxidant potentials, and in vivo antioxidant, renal function and histologic outcomes of TOP extract, TOPE, in MSG-challenged rats after oral exposure for 14 days. In vitro, ferric reducing antioxidant power (FRAP), total antioxidant capacity (TAC) and 2,2-diphynyl-1-picrylhydrazyl (DPPH) scavenging activity of TOPE concentration-dependently peaked at the highest tested concentration. In vivo, MSG caused marked and significant (p < 0.05) alterations of the investigated antioxidant and renal function parameters. TOPE either improved, or elicited similar response on these parameters compared to the control, and dose-dependently (p < 0.05) diminished the MSG-induced effects. Histologic data revealed that the multifocal degeneration of the renal tubular epithelial cells of MSG-induced rats were absent in the control and others indicating significant degree of repair by TOPE in TOPE co-treatment groups. Thus, TOPE has demonstrated in vitro antioxidant capacity and in vivo protective inhibition against nephrotoxicity induced by administration of MSG in rats via probable antioxidant balancing mechanism.

Many countries, as well as several regions in Indonesia, are adopting digital government with the urgency that this approach is helpful as a bridge to good governance. However, more examination is needed to see both the opportunities and obstacles of digital government by assessing cases at the local level. This research analyses the potential and challenges of developing digital government locally with a case study in Central Sulawesi Province. The region was selected for analysis because Central Sulawesi has developed the necessary telecommunications infrastructure and internet access. The study relies on online research methods to collect data and information via the internet and other digital technology. This study employs NVivo 12 Plus for analysis. The findings of this research reveal that Central Sulawesi has great potential in developing digital government, such as optimising data management, accelerating administrative processes and increasing citizen involvement. However, the study also identifies challenges, such as poor access to digital infrastructure in rural areas and limited digital skills among government employees. Therefore, strong efforts are needed to expand the reach of internet access, improve digital skills and increase citizen participation in the development of digital government. This research provides an in-depth understanding of the potential and challenges of developing digital government in Central Sulawesi as well as relevant policy recommendations to increase digital adaptation at the local level.

Jeruk Siompu merupakan tanaman khas Pulau Siompu yang memiliki bau serta rasa manis yang khas dan tidak dimiliki oleh jeruk lainnya. Saat ini hanya tersisa satu desa yang membudidayakan tanaman ini yakni Desa Wandaiwula salah satu desa yang berada di Pulau Siompu. Hal ini terjadi karena perawatannya yang membutuhkan tenaga ekstra, kurangnya ketertarikan mayarakat serta faktor hama juga yang membuat tanaman ini mulai punah. Melihat kondisi yang terjadi saat ini, maka kegiatan ini berupa pendampingan kepada masyarakat khususnya penduduk Desa Wakinamboro Kecamatan Siompu Kabupaten Buton Selatan tentang peningkatan pengetahuan teknik budidaya serta penanaman jeruk Siompu sebagai upaya pelestarian tanaman jeruk dalam memanfaatkan pekarangan rumah dengan sasaran sebanyak 20 orang mitra penduduk Desa Wakinamboro. Metode pengabdian yang digunakan adalah metode pendampingan dengan beberapa langkah tersistematis berupa focus grup discussion, analisis kebutuhan, pelatihan, pendampingan dan evaluasi kegiatan. Hasil yang dicapai setelah edukasi kegiatan adalah peserta memiliki peningkatan pengetahuan terkait teknik budidaya jeruk Siompu dari hasil pengukuran tingkat pengetahuan pretest yakni sebesar 2% peserta paham dan setelah posttest sebesar 96% peserta menjadi paham. Sehingga terjadi kenaikan tingkat pemahaman sebesar 47%. Hasil lainnya dari program pengabdian ini adalah jumlah bibit jeruk yang telah ditanam sebanyak 60 pohon yang nantinya akan dirawat dengan baik oleh mitra sehingga mampu tumbuh dan berkembang dengan baik hingga berbuah.

Gempa bumi merupakan bencana alam yang menjadi ancaman serius di Indonesia, terutama wilayah yang terletak di zona aktif Cincin Api Pasifik. Pemerintah Indonesia secara aktif telah berusaha meningkatkan kesiapsiagaan dan mitigasi terhadap bencana gempa bumi dengan berbagai upaya di tingkat lokal dan nasional. Untuk mencapai hal tersebut perlu adanya sosialisasi kepada berbagai lapisan masyarakat, khususnya pada anak-anak usia sekolah. Kegiatan ini dilakukan di salah satu sekolah dasar di Kabupaten Cianjur, yang pada tahun 2022 telah dilanda bencana gempa bumi. Tujuan kegiatan ini adalah untuk mengevaluasi efektivitas program sosialisasi mitigasi dalam meningkatkan kesadaran dan kesiapsiagaan peserta didik terhadap risiko bencana gempa bumi. Sosialisasi dilakukan dengan pendekatan yang bersifat edukatif dan menghibur menggunakan permainan dan media interaktif berupa komik bergambar bertema “mitigasi bencana gempa bumi”. Komik ini didesain khusus untuk anak sekolah dasar. Dengan melibatkan kolaborasi antara peneliti, guru, dan peserta didik diharapkan dapat terbentuk suatu pemahaman dan budaya baru dalam menghadapi bencana gempa bumi. Metodologi pengumpulan data pada kegiatan ini adalah observasi, tes, dan wawancara guna memperoleh gambaran komprehensif mengenai pelaksanaan kegiatan sosialisasi mitigasi. Hasil evaluasi menunjukkan bahwa kegiatan sosialiasi mitigasi ini mencapai tingkat keberhasilan yang cukup signifikan. Dimana nilai rata-rata pada ketiga indikator (materi, penyelenggaraan, dan pemahaman) mencapai lebih dari 85, serta nilai efektivitas N-gain menunjukkan bahwa pemahaman peserta didik terhadap mitigasi bencana gempa bumi mengalami peningkatan sebesar 48% dibandingkan sebelum mengikuti sosialisasi
