“…Moreover, it holds the potential to aid in the reduction of methane emissions originating from cattle [ 151 ]. Breeding cows with lower methane emissions will contribute to achieving the targets established at the 2015 Paris COP meeting [ 7 , 152 ]. In their study, J. Lassen et al [ 129 ] also examined the genetic correlations between CH 4 emissions and other traits that are important for breeding purposes, such as reproduction and health.…”

The dairy industry is facing criticism for its role in exacerbating global GHG emissions, as climate change becomes an increasingly pressing issue. These emissions mostly originate from methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2). An optimal strategy involves the creation of an economical monitoring device to evaluate methane emissions from dairy animals. Livestock production systems encounter difficulties because of escalating food demand and environmental concerns. Enhancing animal productivity via nutrition, feeding management, reproduction, or genetics can result in a decrease in CH4 emissions per unit of meat or milk. This CH4 unit approach allows for a more accurate comparison of emissions across different animal production systems, considering variations in productivity. Expressing methane emissions per unit allows for easier comparison between different sources of emissions. Expressing emissions per unit (e.g., per cow) highlights the relative impact of these sources on the environment. By quantifying emissions on a per unit basis, it becomes easier to identify high-emission sources and target mitigation efforts accordingly. Many environmental policies and regulations focus on reducing emissions per unit of activity or output. By focusing on emissions per unit, policymakers and producers can work together to implement practices that lower emissions without sacrificing productivity. Expressing methane emissions in this way aligns with policy goals aimed at curbing overall greenhouse gas emissions. While it is true that total emissions affect the atmosphere globally, breaking down emissions per unit helps to understand the specific contributions of different activities and sectors to overall greenhouse gas emissions. Tackling cattle health issues can increase productivity, reduce GHG emissions, and improve animal welfare. Addressing livestock health issues can also provide favourable impacts on human health by reducing the prevalence of infectious illnesses in livestock, thereby mitigating the likelihood of zoonotic infections transmitting to humans. The progress in animal health offers the potential for a future in which the likelihood of animal diseases is reduced because of improved immunity, more effective preventative techniques, earlier identification, and innovative treatments. The primary objective of veterinary medicine is to eradicate clinical infectious diseases in small groups of animals. However, as the animal population grows, the emphasis shifts towards proactive treatment to tackle subclinical diseases and enhance production. Proactive treatment encompasses the consistent monitoring and implementation of preventive measures, such as vaccination and adherence to appropriate nutrition. Through the implementation of these measures, the livestock industry may enhance both animal well-being and mitigate the release of methane and nitrous oxide, thereby fostering environmental sustainability. In addition, advocating for sustainable farming methods and providing farmers with education on the significance of mitigating GHG emissions can bolster the industry’s endeavours to tackle climate change and infectious illnesses. This will result in a more robust and environmentally sustainable agriculture industry. This review seeks to conduct a thorough examination of the correlation between the health condition of cattle, the composition of milk produced, and the emissions of methane gas. It aims to identify areas where research is lacking and to provide guidance for future scientific investigations, policy making, and industry practices. The goal is to address the difficulties associated with methane emissions in the cattle industry. The primary global health challenge is to identify the causative relationship between climate change and infectious illnesses. Reducing CH4 and N2O emissions from digestive fermentation and animal manure can be achieved by improving animal well-being and limiting disease and mortality.

“…Biofuels can be one of the sources to meet global energy needs. Fossil fuels have been used as the primary source of Energy for many years; However, their use is unsustainable and causes environmental problems related to the burning of fossil fuels (Obergassel et al, 2016;Ridjan et al, 2013). Hence, this challenge allows fossil fuels to be replaced by renewable energy sources such as environmentally friendly biofuels (Ridjan et al, 2013) The produced bioenergy/biofuel can replace natural gas, coal, and electricity, currently used in ethanol and biodiesel plants, and could significantly improve the net energy output of biofuel plants.…”

This research describes the evaluation of students when learning videos on renewable energy to increase students' knowledge and awareness about reducing fossil energy. Learning models, namely learning videos and other features, support student learning processes. Some of the learning videos describe Biodiesel or renewable energy sources derived from vegetable resources, namely used cooking oil, which is one of the current crucial problems regarding reducing fossil energy that must be addressed immediately. Students, as the nation's young generation, are less concerned about this problem, so there is a need for a learning model about renewable energy that can increase student knowledge and concern about the current reduction in fossil energy. One alternative learning model to clarify this subject is through Renewable Energy themed Learning Videos in Audio Visual class. The research method used is a descriptive qualitative method and a quantitative method. Respondents in this study were 60 students from the Audio Visual subject group. The Learning Model fully uses Learning Videos. Evaluation of the impact of this learning model shows that, in fact, with this learning model, the knowledge and attention or concern of students increases after participating in the learning process using learning videos with the theme of renewable energy.

Model pembelajaran yaitu video pembelajaran dan fitur lainnya mendukung proses belajar siswa. Beberapa video pembelajaran menjelaskan tentang Biodiesel atau sumber energi terbarukan yang berasal dari sumber daya nabati yaitu minyak jelantah yang merupakan salah satu permasalahan krusial saat ini terkait pengurangan energi fosil yang harus segera diatasi. Pelajar sebagai generasi muda bangsa kurang memperhatikan masalah ini, sehingga perlu adanya model pembelajaran tentang energi terbarukan yang dapat meningkatkan pengetahuan dan kepedulian siswa terhadap pengurangan energi fosil saat ini. Salah satu alternatif model pembelajaran untuk memperjelas mata kuliah ini adalah melalui Video Pembelajaran bertema Energi Terbarukan di kelas Audio Visual. Metode penelitian yang digunakan adalah metode kualitatif deskriptif dan metode kuantitatif. Responden dalam penelitian ini adalah 60 siswa dari kelompok mata pelajaran Audio Visual. Model pembelajaran sepenuhnya menggunakan video pembelajaran. Evaluasi dampak model pembelajaran ini menunjukkan bahwa sebenarnya dengan model pembelajaran ini pengetahuan dan perhatian atau kepedulian siswa meningkat setelah mengikuti proses pembelajaran menggunakan video pembelajaran bertema energi terbarukan.

“…The most recent milestone of global climate policy was the Paris Agreement, accepted on December 12, 2015, which is a legally binding internationally harmonized framework to stop climate change (Dimitrov, 2016). It aimed to prevent the global mean temperature from exceeding the +2 °C considered to be an irreversible turning point relative to the pre-industrial era, and to achieve control even at a level of +1.5 °C (Agreement, P., 2015;Obergassel et al, 2015;Obergassel et al, 2016;Oztig, 2017). The above objective was established in such a way as to allow the maintenance of food production and economic growth at the same time (Rogelj et al, 2016).…”
