Abstract

The environmental challenges facing the African continent are of critical concern, with rapid urbanization, resource depletion, and climate change posing significant threats to its ecological integrity and socio-economic stability. This paper presents a strategy for resolving these problems by enabling citizens to participate in sustainable environmental governance. This suggested framework is based on a multifaceted approach that combines advocacy for public policy, community participation, education, and technological innovation. It underlines the part played by involving citizens in fostering environmental sustainability. The concept of a "New Africa" envisions a populace that is and empowered to actively engage in environmental policy and practice-related decision-making. The emphasis on inclusive and participatory government that results from this paradigm shift ensures that the various views and viewpoints of African communities are heard and valued. African countries will be well-positioned to pave the way for sustainable environmental governance by adopting this forward-thinking paradigm, ensuring the peaceful co-existence of nature and society. The bedrock of this transformative journey will be the empowerment of African citizens, promoting a continent where the environment flourishes and communities prosper side by side. This vision provides a roadmap for a strong and wealthy Africa that is prepared to take on the challenges of the 21st century.

Abstract

The Somali region of Ethiopia, predominantly inhabited by pastoralists, faces serious threats to food security and economy from livestock diseases. Among these diseases, Peste des Petits Ruminants (PPR) and Contagious Caprine Pleuropneumonia (CCPP) are of major concern, especially in small ruminants such as goats, with high morbidity and mortality rates. To evaluate the impact of treatment interventions (administration of 20% oxytetracycline and Penistripe) and mass vaccination campaigns on the morbidity and mortality rates caused by PPR and CCPP outbreaks. The research method will focus on the epidemiological analysis of concurrent PPR and CCPP outbreaks in Jarar and Doollo Zones, Somali Region, Ethiopia in February 2025, by reviewing laboratory confirmation data and responses to interventions. The study will also evaluate the effectiveness of antibiotic treatment and mass vaccination campaigns in controlling the spread of diseases in small ruminants in the region. The research results showed that the detection of PPR Ag in the nasal discharge of infected caprine provided strong evidence of active PPR infection, also the detection of CCPP antibodies in the serum of infected caprine showed clearly active for CCPP infection. The research conclusion is that successfully control the spread of PPR, immediate intervention measures are mandatory, such as vaccinations campaigns, isolation of sick and healthy animals and treatment of infected animals are imperative.

Abstract

Numeracy ability is a basic ability that students must have to face the progress of the times. This ability guides students to analyze and solve mathematical problems and problems in everyday life. Even though it is very important, the numeracy skills of students in Indonesia are still very low. Therefore, efforts need to be made to improve and adjust strategies in the learning process so that students' numeracy abilities can increase. One effort is to use learning media. This research aims to find out what learning media are used by teachers to improve the numeracy skills of elementary school students, especially at the Tahfidzul Quran An-Nahl Mataram Integrated Islamic Elementary School. This research method is through teacher interviews and learning observations for 5 months in the odd semester of the 2023/2024 academic year. There are several media used by teachers in the process of improving numeracy skills at the Tahfidzul Quran An-Nahl Mataram Integrated Islamic Elementary School, including the addition and subtraction board, an introduction to measuring instruments board, rupiah specimen currency media, and a long unit ladder prop. All media used by teachers can increase student activity and involvement, learning outcomes, and student learning motivation.

Abstract

Bi-2212 superconductor has garnered significant interest in recent years due to its potential applications in the development of superconducting wires and tapes. The effect of introducing carbon nanotubes (CNT) into the Bi-2212 system was investigated in terms of superconducting and structural properties. The results of this study indicated that the addition of CNTs had a notable effect on the phase formation of Bi-2212,  with a substantial increase from 86.8% to 97.4% for the sample with a weight percentage of 0.8 wt.%.  This can be attributed to the improved particle orientation brought about by the introduction of CNTs.  The microstructure analysis displayed randomly distributed grains of irregular shapes, with a reduced average grain size of 1.018 μm upon the addition of 0.4 wt.% CNTs. Additionally, the inclusion of CNTs led to an increase in the Tc value, with the maximum Tc-onset recorded at 79 K for the sample containing 0.6 wt.% CNTs.  In summary CNT has enhanced the structural  and the superconducting properties of the Bi-2212 synthesised with thermal treatment method.
