Abstract

Background: Spanish mackerel (Scomberomorus sp.) is one of the high-value fishery commodities that is widely harvested in the Terubuk Fishery Reserve Area, Buruk Bakul Village. The increasing demand and market price of Spanish mackerel have led to high fishing intensity, which may exert pressure on the resource stock. The fishing techniques employed in the mackerel fishery play a critical role in ensuring the sustainability of this resource. This study aims to evaluate the status of Spanish mackerel fishing techniques within the framework of the Ecosystem Approach to Fisheries Management (EAFM). Methods: Data collection was carried out through surveys and interviews with fishers during the period of November–December 2024 in Buruk Bakul Village, Bengkalis Regency. The analysis applied a multi-criteria method using a flag model, which assessed indicators such as destructive fishing practices, gear modification and auxiliary devices, fishing capacity and effort, selectivity of gear, and the compliance of vessel function and size with legal documentation. Findings: The findings indicate that Spanish mackerel fishing techniques in this area fall under the “good” category, with a score of 220. These results indicate that the management of Spanish mackerel in the Terubuk Sanctuary Area, in terms of fishing techniques, remains in good condition and applies the principles of sustainable fisheries. However, several indicators require improvement. Conclusion: The study concludes that Spanish mackerel fishing practices in the Terubuk Sanctuary Area are generally sustainable and categorized as good, but improvements are still needed in fishing capacity and effort, gear selectivity, and vessel compliance. Optimizing these aspects will help ensure the long-term sustainability of the resource while maintaining fishery efficiency.

Abstract

Background: Indonesia, with the fourth largest population globally, faces increasing demand for animal protein, particularly from broiler chicken production. However, this industry is challenged by the avian influenza virus, which causes high mortality in both poultry and humans. The virus’s hemagglutinin (HA) and neuraminidase (NA) glycoproteins are key to its infectivity. Innovative feed formulations that reduce viral titers while maintaining nutritional value are critical. This study aims to develop an innovative broiler chicken feed combining corn and bioactive compounds from ginger (Zingiber officinale) to inhibit avian influenza virus activity and sustain poultry health. Methods: This study employed a descriptive-experimental approach to develop an innovative broiler feed made from ground corn and ginger (JAZI) and to evaluate its effects on physiology, immunity, and growth. The work included research trend related, research manufacturing stage, and implementation stage to assess its practical effectiveness in enhancing broiler productivity and resilience against avian influenza. Findings: Ginger bioactives demonstrated the ability to inactivate viral particles by penetrating the lipid membrane, reducing HA activity, and preventing hemagglutination. Additionally, ginger supplementation was shown to enhance immune responses through activation of T-helper cells and antibody production, improving broiler performance indicators such as feed conversion ratio (FCR) and overall health. The integration of JAZI feed contributes to reduced antibiotic dependence and promotes sustainable poultry farming practices. Conclusion: The JAZI feed innovation provides a natural, safe, and sustainable solution for enhancing broiler immunity against avian influenza through synergistic nutritional and antiviral mechanisms. Novelty/Originality of this article: This study introduces JAZI as a dual-function feed innovation that not only supplies essential nutrition but also acts as an immunostimulant and antiviral agent against avian influenza, aligning with the One Health and Sustainable Development Goals (SDGs 15) frameworks.

Abstract

Background: Pets play an important role in human life. Many studies have shown that the presence of pets can improve the physical and mental health of their owners. The relationship between owners and pets tends to result in more positive behavior from owners towards other animals. Zoos are one of the locations where humans interact with various animals. The presence of humans (visitors) in zoos harms animal welfare in that location. Therefore, this study aims to determine the effect of pet ownership on perceptions of animal welfare in zoos. Methods: This study uses a quantitative method that examines the impact of pet ownership on perceptions of animal welfare in zoos. Through quantitative methods, a survey was conducted to collect data on public perceptions, both pet owners and non-owners, to see their perceptions of animal welfare in zoos. Findings: The study's results revealed that pet owners had higher HAIS values ​​than those who did not have pets. Then the perception of animal welfare in general showed that pet owners tended to have lower perceptions of animal welfare than non-pet owners. The relationship between the level of relationship closeness between humans and pets and the perception of animal welfare showed a low negative correlation, which means that the higher the HAIS value, the lower the perception of welfare towards zoo animals. Pet owners tend to be more sensitive to the conditions of animals that are less than ideal. The following research reveals that positive human interactions with pets will encourage positive behavior toward other animals. Conclusion: This study concludes that pet owners have a more critical perception of animal welfare in zoos than visitors who do not have pets. The level of closeness of interaction also influences the critical behavior of pet owners towards animal welfare conditions in zoos. Novelty/Originality of this article: The novelty of this study lies in identifying the perceptions of zoo visitors through their level of interaction with pets. This study is unique because it uses the closeness level of interaction with pets to see the zoo visitor's perceptions of animal welfare in zoos.

Abstract

Background: Nutritional disparities remain a major challenge in Indonesia’s human resource development, as the prevalence of stunting and wasting continues to vary widely across regions despite measurable national progress. These inequalities highlight the need for integrated and sustainable agricultural innovations that improve both food quality and availability while maintaining ecological balance. This study aims to analyze the potential of the Integrated Crop–Livestock System (ICLS) 5.0 as an innovation that strengthens food security and enhances nutritional value through sustainable resource management. Method: A quantitative descriptive approach based on a comprehensive literature review was conducted using secondary data from scientific journals and national databases. The ICLS 5.0 framework emphasizes circular resource use, converting agricultural residues such as rice straw, corn stalks, and dry leaves into fermented forage, while livestock manure is processed into organic fertilizer through bioactivation and composting. Data were analyzed to assess improvements in productivity, soil fertility, and resource efficiency. Finding: Implementation of the ICLS 5.0 model can increase agricultural and livestock productivity by 30–40%, enhance soil carbon and nitrogen content, and reduce production costs by 30–50% through the substitution of chemical fertilizers and industrial feed. The system also reduces greenhouse gas emissions and improves food self-sufficiency in rural areas by promoting local feed and fertilizer production. Conclusion: The ICLS 5.0 approach provides a low-cost, scalable, and knowledge-based innovation that aligns with national efforts to strengthen food and nutrition security. By integrating crops and livestock within a circular economy framework, this model supports sustainable agricultural intensification and contributes directly to achieving Sustainable Development Goals (SDG 2 Zero Hunger, SDG 12 Responsible Consumption and Production, and SDG 13 Climate Action), while enhancing the resilience and welfare of rural farming communities. Novelty/Originality of this article: This innovation introduces an adaptive crop–livestock integration model suitable for various land scales, complemented by a localized ICLS framework. It also provides simple technical guidelines for converting organic waste into fertilizer, feed, or energy, along with the development of micro-scale circular economy systems for farmer and livestock groups.

Abstract

Background: Soil degradation in Indonesia is a serious challenge, impacting agricultural productivity and environmental quality. One potential ecological solution is bioremediation using soil microorganisms such as Trichoderma spp. This study aims to identify local Trichoderma isolates from various regions in Indonesia along with their biological and functional characteristics in the bioremediation process. Method: This study uses a narrative literature review to synthesize conceptual and empirical evidence from academic journals, scientific articles, and policy reports. This review focuses on assessing the biological and functional characteristics of local Trichoderma isolates and their effectiveness in addressing unsustainable soil management and environmental degradation. Finding: The results of the literature study indicate that species such as Trichoderma harzianum, Trichoderma viride, Trichoderma asperellum, and Trichoderma koningiopsis can degrade organic and inorganic pollutants, suppressing pathogens, and improving soil fertility. The potential of each isolate is strongly influenced by its environmental origin and type of pollutant, with high effectiveness recorded in ex-mining soil, agricultural land, and pesticide-contaminated areas. Further research and policy support from research institutions or relevant parties are needed so that local Trichoderma can be developed as a bioremediation agent in sustainable agricultural systems in Indonesia. Conclusion: Local Trichoderma species offer a significant and sustainable solution for restoring soil health in Indonesia, provided that challenges related to technology adoption and isolate data can be overcome. Future success depends on cross-sector collaboration to bridge the gap between laboratory research and field application, ensuring that these biological agents are optimized through farmer education and regulatory support. Novelty/Originality of this article: This study presents a comprehensive synthesis of native Indonesian Trichoderma isolates, identifying a direct relationship between their geographic origin and their specific multifunctional effectiveness.
