Questionnaires emerged as the dominant data collection technique, while quantitative analysis methods were more frequently employed. Furthermore, the geographical distribution of CS research revealed a concentration in America and Europe. Notably, the application of CS research remains limited in Asia and Africa. An additional finding suggests a gap in research focusing on educational themes, particularly those exploring the involvement of educatorstudents, a local traditional leader in Citizen Science Project Keywords: citizen science. research trends. systematic literature review INTRODUCTION Citizen Science (CS) has become a widely used and increasingly popular scientific It involves the collaboration of volunteers and professional researchers to generate new scientific knowledge (Bonney et al. , 2. The value of CS in fostering a closer relationship between society and science by promoting deeper public engagement in issues concerning environmental risks and threats. In citizen science project (CSP), communities and stakeholders actively participate in research programs, such as data collection and large-scale surveys (Oturai et , 2. CSP encompass a wide range of topics, including reptile biodiversity identification (Wangyal et al. , 2022. , plastic pollution (Heinimyki et al. , 2021. Kiessling et al. , 2. , aquatic vegetation identification (Webster et al. , 2. , air pollution monitoring (Abhijith et al. , 2. drinking water pollution surveys (Redmon et al. , 2020. Segev et al. , 2. , building structure identification for disaster mitigation (Scaini et al. , 2. , bat ecology observations (Greving et al. , and coral reef monitoring (Meschini et al. , 2. These projects contribute significantly to improved environmental policies, benefiting stakeholders. Therefore, participants in CSP play a critical role by actively engaging in research. Beyond scientific contributions. CS fosters proenvironmental attitudes within society. It serves as a process that actively involves citizens in scientific development or alongside researchers, thus functioning as a bridge between scientists and the public (Thompson et al. , 2. With the growing disconnect between humans and nature (Soga & Gaston, 2. CS offers an opportunity to reconnect with the natural world and Journal of Natural Science and Integration. Vol. No. October 2019, pp 214-234 | 214 Research Trend of Citizen Science Themes 2019-2024: Systematic Literature Review contribute meaningfully. In conclusion. CS presents a valuable avenue for public participation in research, ultimately leading to environmental improvements. CS has a long history of contributing to the advancement of natural science, which itself encompasses the study of both life science and physical science (Erduran et al. , 2. Key characteristics of natural science include observation of phenomena, hypothesis testing, and One of the earliest examples is the meticulous recording of cherry blossoms blooming in Kyoto. Japan, dating back to 801 AD, by individuals like merchants, politicians, and monks (Aono & Kazui, 2. Further historical accounts demonstrate the close connection between CS and natural science, as exemplified by the inherent curiosity and enthusiasm for understanding nature displayed by figures like explorers Alexander von Humboldt. Ferdinand Myller, and Maria Sibylla Merian (Vohland et al. , 2. The past two decades have witnessed a surge in CSP, fueled by the advancement of internet technology. This has significantly enhanced project visibility, functionality, and accessibility (Scheibner et al. , 2. The online realm empowers individuals interested in diverse areas like fish observation, beetle research, environmental pollution monitoring, and educational initiatives to discover relevant CSP. Participants can readily access project instructions, actively contribute data directly to online databases (Phillips et al. , 2. , and become integral parts of the scientific process. Furthermore, the internet has fostered the emergence of a new CS paradigm based on crowdsourcing (Bonney et al. , 2. Projects like Galaxy Zoo exemplify this approach, inviting the public to classify astronomical images captured by the Hubble Space Telescope (Raddick et al. , 2. As space exploration initiatives continue to generate vast datasets,CSP focused on data transcription, management, and interpretation are rapidly gaining traction. For instance, iNaturalist leverages smartphone applications to engage participants in documenting plant and animal species encountered in their natural habitats (Echeverria et al. , 2. This data serves as a valuable resource for scientists studying biodiversity patterns and species change over Similarly. FrogWatch USA mobilizes volunteers to monitor frog populations within their local backyards (Nemec et al. , 2. This data provides scientists with crucial insights into frog population health and the impact of factors like climate change. Beyond direct data collection. CSP offers opportunities for public participation beyond Projects like Riverkeeper Water Watch in New York engage volunteers in water quality monitoring of rivers and streams by measuring parameters like temperature, pH, and dissolved oxygen levels (Forrest et al. , 2. This data empowers scientists to assess the health of waterways and identify potential pollution sources. Notably. CS encompasses both data collection and data analysis efforts. While some projects focus on field data collection, others harness the public's collective intellect to analyze vast datasets that would otherwise be unmanageable. In this way, the public plays a pivotal role in advancing scientific discovery. The 21st century is characterized by complex and multifaceted global challenges, including climate change, biodiversity loss, and environmental pollution (Singh, 2. emerges as an innovative approach to tackle these challenges by harnessing the collective power of the public. It allows individuals from diverse backgrounds and varying levels of expertise to participate actively in scientific research, thereby fostering greater inclusivity and diversity within the scientific community (Cooper et al. , 2021. Roche et al. , 2. One crucial advantage of CS lies in its ability to address the limitations faced by scientists in collecting data, particularly for large-scale, long-term studies like those related to climate change (M. Haklay et al. , 2. engaging a wider community in data collection. CSP can contribute to the generation of more comprehensive and geographically extensive datasets. However, it is crucial to acknowledge that data collected by the public may exhibit variability in accuracy and consistency. Therefore, the role of scientists remains essential in validating and ensuring the integrity of the data, thereby mitigating potential biases in interpretation (Bowser et al. , 2. This collaborative effort fosters Journal of Natural Science and Integration. Vol. No. October 2024, pp 214-234 | 215 Aldeva Ilhami. Topik Hidayat. Riandi a mutually beneficial relationship, enabling the public to gain valuable insights from scientific data and utilize it for informed decision-making at the community level. CS also holds significant promise in supporting the achievement of the Sustainable Development Goals (SDG. established by the United Nations in 2015. These 17 interconnected goals, encompassing areas like health, education, environment, and social justice, aim to eliminate global challenges such as poverty, hunger, and inequality (UNRP, 2. CSP can contribute to this agenda by collecting and monitoring crucial environmental, social, and health data, complementing and strengthening the efforts of government agencies and research organizations (Chapman & Hodges, 2. Examples include monitoring water quality (Redmon et al. , 2. tracking invasive species (Colombari & Battisti, 2. , monitoring coastlines (Harley & Kinsela, 2. , and assessing plastic waste pollution (Clark et al. , 2. Furthermore. CSP play a vital role in raising public awareness about the SDGs and educating the public on the importance of sustainable development. The data and information obtained through these projects can then inform evidence-based policymaking, allowing policymakers to create targeted and effective interventions aimed at achieving the SDGs (Criscuolo et al. , 2. In conclusion. CS presents a powerful tool for addressing global challenges and achieving sustainable development in the 21st By fostering public participation in scientific research, facilitating data collection, and raising awareness about critical issues. CS paves the way for a more inclusive, collaborative, and informed approach to tackling the complex problems facing our planet. CS has demonstrably been and will continue to be, critical to the advancement of the natural sciences (Bonney et al. , 2. Sharing a core objective Ae unearthing the mysteries of the natural world Ae CS and natural science operate in a mutually beneficial synergy. This shared mission motivates volunteers to dedicate their time and effort to a diverse array of crowdsourcing initiatives that leverage citizen contributions through large-scale observations (Haklay et al. The societal contribution to the evolution of the natural sciences is well-documented (Cooper et al. , 2. Current classifications of CSP recognize them as approaches holding significant promise for the future of scientific exploration. Examples abound, offering communities the opportunity to employ scientific methods to quantify the severity and distribution of air pollution, thereby facilitating environmental justice initiatives (Fogg-Rogers et , 2. Similarly. CS empowers communities to engage in sustainable water management practices (Pandeya et al. , 2. and contribute to the monitoring of endangered species (Lloyd et , 2. Expanding opportunities for citizen involvement throughout various stages of scientific discovery promises to enhance public scientific literacy (Brandt et al. , 2. When meticulously planned, a vibrant CS community can provide holistic insights into the critical challenges confronting our world in the 21st century. A significant segment of CSP focused on biodiversity aims to map species distribution and quantify their populations. Data collected through such projects . , eBird , iNaturalist, iSpo. informs various studies, enabling researchers to track population trends and map species ranges. The accelerated pace of global change necessitates a corresponding expansion of CS across various sectors (Haklay et al. , 2. Beyond biodiversity. CS holds significant potential for data collection on a broad spectrum of issues, including ecological monitoring, pollution distribution, and risk factor identification. The diverse applications of CS across multiple fields serve as a powerful testament to society's immense capacity to contribute meaningfully to scientific Through active community participation. CS can offer solutions to various challenges and ultimately improve the quality of human life. This research aims to explore thematic areas and evaluate the implementation of previously executed CSP.

Selection and Extraction of data for SLR Environmental pollution poses a significant threat to our planet, with specific concerns surrounding waste pollution's detrimental impact on aquatic ecosystems and the wider Studies have highlighted the transportation of vast amounts of plastic waste from rivers to the ocean (McCormick & Hoellein, 2016. Meijer et al. , 2021. Vigneswaran et al. , 2. contributing to environmental, economic, and social challenges. Estimates suggest that annually, 8 million tons of plastic waste enter the sea through rivers, highlighting the critical need for effective waste management (Schmidt et al. , 2. Recent research further underscores the Journal of Natural Science and Integration. Vol. No. October 2024, pp 214-234 Research Trend of Citizen Science Themes 2019-2024: Systematic Literature Review widespread impact of anthropogenic waste on wildlife, such as the consumption of microplastics by freshwater fish (Li et al. , 2. and the incorporation of plastic into bird nests (Votier et al. Additionally, consuming water contaminated with microplastics poses a potential health risk to humans. Public interest in monitoring water and air pollution is on the rise. This translates to increased community participation in hydrological studies, encompassing data collection related to both water quantity and quality (Buytaert et al. , 2014. Njue et al. , 2. The multifaceted objectives of community-based water quality monitoring projects lead to diverse approaches, involving variations in focus, methodologies employed, and sampling frequency. Similarly, communities are increasingly involved in air quality monitoring, often utilizing bioindicators such as lichens (Counoy et al. , 2. Project durations vary, with some campaigns spanning multiple years, while others operate for several months (Jones et al. , 2022a. Kiessling et al. , 2021. Gynner et al. , 2023. Wichmann et al. , 2. The methods chosen for collecting water and air quality data depend on several factors like the specific pollutants or characteristics being volunteer availability. the number of volunteers participating in data collection. budget and duration, financial resources, and the timeframe allocated to the project. These factors, in turn, influence the spatial and temporal resolution of the collected data, ultimately impacting its value for various hydrological studies. For example, one-time sampling events often involve large volunteer groups and utilize cost-effective methods. While this approach offers broader spatial coverage, the resulting data may have lower precision (McKinley et al. , 2. This trade-off between scale and accuracy represents one of the key challenges and limitations inherent in CSP projects. Figure 2. Popular theme of CSP CS offers a compelling solution to overcome large-scale conservation challenges by leveraging its inherent broad reach and community involvement. Community engagement, including students, can be better at helping with decision-making (Gusti et al. , 2. This fosters better-informed decision-making on conservation policies and outcomes. Similar to conventional research. CS strategies employed for conservation advancements involve acquiring scientific knowledge (McKinley et al. , 2. Volunteers play a crucial role in generating valuable scientific information that aids conservation scientists, natural resource and environmental managers, and CS influences decision-making and fuels community engagement in managing and formulating policies related to natural resources and the environment (Hyder et al. , 2.

CSP plays a pivotal role in environmental improvement by contributing to building scientific knowledge. Providing valuable input for policy formulation. and inspiring community action By harnessing the collective power of CSP, communities can actively participate in addressing the critical conservation challenges we face today. Distribution of CSP locations in the last five years CS has witnessed rapid growth across various nations worldwide, fueled by a confluence of factors: technological advancements, heightened public awareness, and a growing need for data (Follett & Strezov, 2015. Newman et al. , 2. The internet and other communication technologies have facilitated public participation in scientific research, while the public itself demonstrates an increasing desire to contribute to scientific endeavors. Additionally, scientists require more data to address complex issues, and CS offers a valuable avenue for data collection. Beyond data collection. CS allows for the refinement of research questions. Project participants, immersed in their local environments and natural resources, can contribute valuable insights that enhance the relevance and local applicability of research questions, ultimately benefitting both scientists and local communities (Herodotou et al. , 2. Recent years have seen a burgeoning of CSP initiatives across multiple countries. Notably, conservation efforts have been at the forefront of these projects. Prominent examples include large-scale initiatives in the United States . ttps://participatorysciences. Europe . ttps://w. ngo ), and Australia . ttps://citizenscience. au ). This growth is driven by the recognition of the potential that CS holds by government agencies, universities, and national/international organizations. Consequently, new organizations dedicated to CS-based research, often with conservation goals, have emerged (Ellwood et , 2. Countries Percentage Journal of Natural Science and Integration.

While the United States and Germany remains the largest contributor with 15%, significant participation is also observed in several European nations: United Kingdom . %). Indonesia . %). Italy . %). Australia. Greece. Austria and France also demonstrates notable engagement . %). While CSP in Asia and Africa remains less prevalent, with recent projects identified in Taiwan and Bhutan . %), and Egypt. Libya . %), the spread of this collaborative approach has demonstrably reached these continents. While parallels are often drawn between early scientific endeavors and today's public involvement , the scale and depth of modern engagement surpass previous forms of This holds even in areas like astronomy and ecological observation, where changes in participant skill sets and knowledge are evident (Haklay, 2. Europe stands out as a global leader in CS development, driven by factors common to other regions, alongside unique strengths like Government support. High-quality human resources, and Diverse environmental Wagenknecht et al. , highlight the role of government funding in fostering CS Haklay . emphasizes the importance of a skilled workforce for successful CS Cardoso et al. point out the unique environmental issues. Europe faces, which necessitate citizen involvement. Several European nations, including Germany. England, and the Netherlands, exemplify this leadership by providing financial and infrastructural support for CS Notably. Europe has a strong tradition of scientific research, which fosters collaboration between academia and society. The global expansion of higher education is another significant factor influencing CS Developed countries, for instance, have witnessed a dramatic increase in tertiary education attainment (Haklay, 2. The UK saw a rise from 1. 6% of the population holding a tertiary degree in 1950 to 21. 7% in 2010. This trend, observed across developed nations, suggests a growing societal orientation towards scientific thinking, creating a fertile ground for CS CSP remains underutilized as a tool for sustainable development, particularly in Asia and Africa (Cardoso et al. , 2. However, emerging projects showcase the possibilities. In Taiwan. A collaborative effort by regional educational and park authorities launched a CS project in 2017 focused on land crab protection (Hsu et al. , 2. The project involves assisting crab migration during breeding season, monitoring species populations, collecting ecological data, and promoting environmental education. In Bhutan. Wangyal et al. highlight the exceptional opportunity for CSP to reveal amphibian and reptile distribution in Bhutan. This opportunity stems from the country's high forest cover, low human population density, and minimal environmental degradation compared to neighboring regions. Therefore. CSP holds significant potential for both biodiversity exploration and potential species discovery. Aripin et al. demonstrate the application of CSP within the context of Indonesian mango plantations. These examples demonstrate the growing potential and diverse applications of CSP in Asia and Africa. As CS continues to evolve, it holds immense promise for advancing scientific research, promoting environmental stewardship, and fostering collaborative solutions to global challenges across all continents.

Popular data collection methods in CS research CS empowers the community to collaboratively collect valuable data through various This data and the resulting information become valuable resources for scientists, decision-makers, and the public alike. One key method of public contribution is crowdsourcing, where a large number of individuals participate in data processing and analysis. CSP can utilize diverse data collection instruments, including questionnaires, observation sheets, interviews, and secondary data collection. These structured surveys gather quantitative data from participants, as exemplified by Hsu et al. who measured environmental literacy levels. These standardized forms record specific observations, allowing for standardized data collection across participants. In-depth interviews gather qualitative data and deeper insights, as seen in Colombari & Battisti's . study measuring participant understanding of biological threats. Existing data from databases can be repurposed for CSP enriching the overall data pool. Data collection methods in CSP facilitate public participation and empower citizens to contribute to research. The predominant approach is utilizing questionnaires . %) to gauge participant understanding, perceptions, and attitudes (Rameshbhai Patel & Joseph, 2. These structured surveys gather quantitative data through written questions designed to elicit specific information and opinions. Observation methods also play a significant role, with field observation . %) and data observation from project databases . %) being common examples. eBird . ttps://eBird . org/hom. , launched in 2002, exemplifies this approach. This program, a collaboration between the Cornell Lab of Ornithology and the National Audubon Society, engages a vast network of citizen scientists who report bird sightings using standardized eBird aims to leverage the collective power of everyday birdwatchers to gain a deeper understanding of bird distribution and abundance across diverse spatial and temporal scales (Rameshbhai Patel & Joseph, 2. Similarly, the French CSP Farmland Biodiversity Observatorium (FBO), launched in 2011, involves 1,216 farmers monitoring biodiversity on their farms (Billaud et al. , 2. This project ensures a comprehensive representation of agricultural practices and crop distribution across France. The late 20th and early 21st centuries witnessed a technological revolution that significantly impacted data collection in CSP. This revolution enabled the capture of diverse data Journal of Natural Science and Integration. Vol. No. October 2024, pp 214-234 | 225 Aldeva Ilhami. Topik Hidayat. Riandi types, including images, video, and sound, which support and facilitate the exploration of new research questions (Johnson et al. , 2. Technological advancements have also fostered the development of networks that enable data sharing through the Internet, creating globally accessible datasets (Aristeidou & Herodotou, 2. For effective CSP, technological tools must be accessible, usable, and useful. Fortunately, recent advancements have addressed these aspects: accessibility, usability, and usefulness. Hardware costs have gradually decreased, improving access to technology for wider participation. Advancements in design and sensors have led to more user-friendly and intuitive tools. Modern sensors, like digital cameras, audio recorders. GPS devices, drones, and eDNA sampling kits, empower volunteers to collect vast amounts of data in the field. Mobile phones have emerged as powerful tools for CSP, driven by their widespread adoption and ability to capture and transmit data efficiently (Aristeidou et al. , 2021. Longo et al. This technology facilitates local participatory monitoring, such as the EpiCollect platform (Dunbar-Wallis et al. , 2. , and global CS initiatives, exemplified by eBird (Sullivan et al. , 2. However, unequal access to mobile technology presents a challenge. Studies like Beza et al. highlight this disparity. while over 90% of surveyed farmers across India. Honduras, and Ethiopia owned phones, less than 60% had consistent network connectivity and even fewer (<10%) used mobile internet. This disparity extends to smartphone ownership, which varies significantly between developed and developing countries (Silver, 2. While developed nations like South Korea boast high ownership rates . %), others like India. Kenya, and Nigeria . A%). These disparities are further exacerbated by variations within countries based on factors like network access, income, education, and location . ural vs. Despite these challenges, the untapped potential exists in regions like Bhutan, where most individuals carry internetconnected phones with cameras and actively share wildlife photos on social media (Wangyal et , 2022. This highlights the potential of CS in generating data for understudied taxonomic groups like reptiles and amphibians. Technological advancement plays a crucial role in enhancing community participation by providing accessible online tools. The information technology revolution, with the rise of the internet and mobile technology equipped with location features, cameras, and sensors, has significantly expanded the capabilities and impact of CS (Toerpe, 2. Platforms like social media . Facebook. Twitte. serve as valuable tools for organizing, monitoring support, and facilitating knowledge sharing among participants. For instance, the Garden Bioblitz in England . ttps://w. org/events/mount-tamalpais/fungi-and-friends-bioblit. utilizes social media to establish new projects and foster collaboration. This ability to access, store, manage, analyze, and share data on a large scale underlines the potential of technology to further enhance CSP endeavors. CONCLUSION CSP is experiencing a surge in interest, with environmental pollution and conservation emerging as prominent research themes. Within the pollution domain, water and air quality monitoring appear to be the most popular topics. Conservation efforts often prioritize animal Quantitative data collection techniques are currently predominant in CS projects.
