Implementation of Production Sharing Agreements for Agricultural Land in Indonesia
Authors: Hutapea Maria , Krismantoro D. , Joe Christian
Published: February 2025

Production Sharing Agreement is an agreement made between the owner and the cultivator of paddy land. The cultivator is asked by the owner to work or cultivate the owner's paddy field whose object is not the paddy field but something attached to the paddy field such as rice plants. The problem in this study is how the implementation of profit-sharing agreements for paddy fields in Indonesia. The research method used is normative juridical. The data source used is secondary data. The method of data collection is done by means of literature study. Data processing is done by means of descriptive analytics. Based on Law Number 2 of 1960 concerning Production Sharing Agreements that in Indonesia it is required that the production sharing agreement must be made by the owner witnessed by two witnesses, each from the landowner and cultivator. In reality, production sharing agreements made by the Indonesian people are still based on customary law so that the agreement is only done orally, not made before the village head and not witnessed by witnesses.

Published: February 2025

This study aims to analyze the development of research related to “futures options” using a bibliometric approach based on Scopus data with the keyword “futures options,” covering 280 journal articles for the period 1973-2024. The analysis was conducted using Biblioshiny in R-Studio for bibliometrics and VOSviewer for keyword network visualization. Results showed that dominant themes included implied volatility, stochastic volatility, and price dynamics with a focus on hedging strategies, risk, and derivatives market dynamics. The network visualization revealed modern themes such as sustainability and climate change, indicating the potential integration of these financial instruments with global sustainability issues. Inter-author collaboration was high, averaging 2.22 authors per document, with 22.5% of documents involving international authors. The study also noted high relevance with the average citations per document reaching 24.81 and an annual growth rate of 2.76%. Temporal analysis showed a significant increase since the 1980s, a peak in 2010-2020, and a decline in 2020-2024, influenced by shifts in research focus or the impact of the COVID-19 pandemic. Visualization through VOSviewer identified five main clusters, with implied volatility having strong connections to hedging and stochastic volatility, while new themes such as sustainability are still in the early stages of exploration. The study concludes that while the futures options theme is mature, there are opportunities for exploration in lesser explored topics such as the integration of sustainability issues and cross-regional analysis, providing a comprehensive picture of the research landscape and future directions.

Waste management based on the Reduce, Reuse, Recycle (TPS3R) Waste Management Site is one of the strategic efforts implemented at the village level, such as in Abiansemal Village, Badung Regency, Bali Province. This study analyzes the challenges and opportunities in implementing TPS3R-based waste management policies using the Advocacy Coalition Framework (ACF). The ACF identifies advocacy coalitions of actors with similar interests, beliefs, and values in driving policy change. The study results show various problems in the management of TPS3R, including a lack of public awareness, limited infrastructure and facilities, lack of sustainable funding, and weak institutions. External factors, such as regulatory changes and global pressures, affect policy effectiveness. ACF's analysis reveals that multi-stakeholder collaboration, including government, private sector, and community, is essential to achieve the sustainability of these programs. The solutions offered include increasing public awareness, strengthening infrastructure, adopting community-based business models, building institutional capacity, and coordination between stakeholders. With effective implementation, TPS3R can become a model for sustainable waste management at the village level, supporting the achievement of environmental targets and sustainable development.

Authors: Alifa Nabiela Rizki , Sutisna Fajar Andrian
Published: February 2025

Digitalization has become a disruption worldwide, including in Indonesia. One dominant aspect of this phenomenon is digital transactions. Bank of Indonesia (BI) reported that the cumulative value of electronic money transactions for the period of January to August 2024 reached IDR 1.6 quadrillion, representing a 35.76% growth compared to IDR 1.18 quadrillion (yoy). This highlights the role of digital transactions as a solution and convenience for various activities, including online crowdfunding. Crowdfunding is a rooted culture in Indonesia and demonstrates sustainable economic benefits in West Java. This activity does not always run smoothly, as issues arise within crowdfunding management institutions, leading to societal trust issues. Based on this phenomenon, strengthening the digital ecosystem in West Java is worthy of study. This research aims to measure society's digital competence level about digital transaction activities, particularly crowdfunding. This research uses a descriptive analysis method with a quantitative approach. Primary data from 258 respondents were obtained through questionnaire distribution targeting urban and rural communities in West Java was employed. The data were analyzed using simple regression analysis. The results show that the level of digital competence in society is not yet optimal; however, digital competence significantly influences digital transaction activities positively. Therefore, exploration is needed to establish credible crowdfunding management in West Java.
INVESTIGATING RECONTEXTUALISATION PROCESSES IN SCIENTIFIC DIGITAL PRACTICES: THE SCIDIS DATABASE
Authors: Pascual Daniel , Sancho-Ortiz Ana Eugenia
Published: February 2025

Scientific communication is exploiting innovative dynamics of research dissemination and knowledge transfer through digital platforms which allow for the wide circulation of disciplinary information for diversified audiences. Against this backdrop, recontextualisation is a key phenomenon, enhanced by medium-dependent affordances, the combination of semiotic modes and users’ discursive choices. In this paper, we present and justify the SciDis Database, collected to analyse this complex phenomenon in various digital scientific dissemination practices, including X/Twitter and Instagram posts, research digests, feature articles, Ask-an-Expert sites, The Conversation platform, explainers, and lay summaries. We conceptualise each of them, considering two parameters to frame them: whether they represent web-hosted or social media practices, and whether they entail author-generated or writer-mediated knowledge. Exploitations and applications of the SciDis Database are emphasised in connection with digital discourse analysis and digital pragmatics, multimodally-oriented approaches, knowledge communication frameworks, and ethnographically-informed studies.

Etimologías del caló en el Diccionario de la Lengua Española de la Real Academia Española: comentario y análisis de algunos ejemplos
Authors: Macías Couso Alba
Published: February 2025

En este trabajo partimos de la hipótesis de que la falta de rigor presente en la lexicografía caló – llevada a cabo principalmente por aficionados y no lingüistas –  se refleja en los diccionarios generales de la lengua. Por lo tanto, nos proponemos analizar las etimologías de los gitanismos incluidos en la versión en línea del Diccionario de la Lengua Española (DLE) de la Real Academia Española, analizando la correspondencia de estas etimologías con las informaciones consignadas en distintas obras de lexicografía gitano-español. Para ello, extraeremos la etimología de aquellas palabras del DLE que incluyan caló como étimo para, posteriormente, localizarlas en una selección de seis diccionarios gitanos. Tras esto, seleccionaremos una muestra de ejemplos, tomando aquellos más relevantes, para llevar a cabo un análisis en base a las informaciones proporcionadas por diferentes autores con la finalidad de detectar problemas etimológicos e intentar clarificar si realmente estamos ante vocablos de origen gitano.

Authors: Alonso Simón Lara , Fernández-Pampillón Cesteros Ana María , Fernández Trinidad Marianela , Márquez Cruz Manuel
Published: February 2025

La cuestión que se aborda en este trabajo de investigación es la comprobación, mediante técnicas estadísticas, de que los modelos generativos de lenguaje GPT-3.5 (versión gratuita) y GPT-4 (versión de pago) de ChatGPT tienen un estilo de escritura distinto al de los humanos, y que pueden diferenciarse, al menos, por tres tipos de rasgos: léxicos, signos de puntuación y estructura sintáctica de las oraciones. Determinar si los grandes modelos de lenguaje tienen un estilo propio es relevante de cara a poder detectar la autoría automática de los textos. En trabajos anteriores se construyó un corpus comparable de textos humanos y automáticos en español y, mediante un estudio cualitativo, se localizó un conjunto de rasgos lingüísticos y estilísticos propios de cada autor. En este trabajo se ha podido comprobar cuantitativamente que 17 variables lingüísticas presentan diferencias estadísticamente significativas entre autores humanos y los modelos GPT-3.5 y GPT-4.

Authors: Risqa JL Ana , Alhaq Arini , Nissa Nurhayatin
Published: February 2025

Dengue Hemorrhagic Fever remains a significant global concern, with its complex distribution influenced by geographic and demographic factors. Indonesia, particularly the city of Bandar Lampung, is an endemic area for Dengue Hemorrhagic Fever. Factors such as population density, area, and geographical coordinates are believed to influence the spread of the disease. Bandar Lampung, which has the highest population density in the region, has recorded a high population growth rate. In this context, multiple linear regression analysis is an effective approach to understanding the relationship between dependent and independent variables, including population density, area, longitude, and latitude. These factors play a crucial role in the transmission of the dengue virus, with high population density increasing human-mosquito interactions. This analysis is expected to provide comprehensive insights to design more effective and targeted intervention strategies for preventing and controlling the spread of Dengue Hemorrhagic Fever at both geographic and demographic levels

Authors: Nikmah Rohmatun , Sari Reni Permata
Published: February 2025

The current era has seen rapid technological progress, notably in gadgets. However, excessive gadget use, particularly among preschoolers, reveals detrimental effects on their social and emotional development. Data from the Indonesian Ministry of Health highlights that about 16% of Indonesian toddlers experience social and emotional disorders linked to excessive gadget use. Initial studies show that limited gadget exposure correlates with better social and emotional development. The present study, comprising a cohort of 96 respondents, has elucidated a significant correlation between gadget usage and the social and emotional maturation of preschool children. Empirical findings corroborate that restrained gadget usage correlates positively with favorable social and emotional developmental outcomes. Dissemination of this knowledge can be effectively facilitated through mediums such as leaflets, videos, or parenting presentations. Collective endeavors are imperative to ensure equitable growth and development among children in this era characterized by rapid technological advancements
Ecological Footprint and Carrying Capacity of the Agricultural Water-Land-Energy Nexus in China
Authors: Dr. Yasmin Akhtar  , Dr. Fatima Gulzar  , Shazia Khalid  , Kashif Raza
Published: February 2025

Regarding water and land use, China's farming industry is unrivalled. Energy consumption and carbon production are two sides of the same coin for the agricultural sector. Utilising approaches to agricultural water pollution, biological ecological footprint, energy ecological footprint, and carrying capacity, this research investigates the ecological pressure index of agricultural water-land energy in China and the spatiotemporal patterns of resource depletion. The main results are as follows: There was an upward trend in China's agricultural BEF, reaching almost 66% of the total in 2020. Although it decreased, the ecological impact of PEF (acid runoff from farms) remained high at around 33%. Agricultural energy usage, on the other hand, has the lowest EEF. Over the last 20 years, there has been a 114.663% increase in agriculture's total ecological footprint (TEF) per person. Ecological footprints per hectare of agricultural land ranged from 3.16 to 3.63 hectares. There has been a substantial increase in ecological efficiency in the agricultural sector. Shandong, Henan, and Heilongjiang provinces have among China's highest TEFs. Sichuan, Tibet, and Hunan are the three provinces with the highest agricultural total ecological capacity (TEC). With stress indices (TEF/TEC) of 1.42 and 1.14, respectively, Tianjin and Henan provinces have the highest levels of agricultural ecological stress. Sustainable crop production is hindered because of the significant disparity between the demand for and availability of natural resources in agriculture. In addition to offering strategies and ideas for fostering sustainable agricultural expansion, the results may shed light on the causes and dynamics of resource pressure in agriculture across different eras and regions.
Nostalgia and Dystopia in Chinua Achebe’s There Was a Country (2012)
Authors: Zahra Saeed
Published: February 2025

This paper explores the psychoanalytic experience of nostalgia in a dystopian society as depicted in Chinua Achebe’s There Was a Country (2012). Achebe’s memoir provides an account of Nigeria’s sociopolitical landscape during and after its independence, particularly focusing on the Nigerian Civil War (1967–1970) and the loss of Biafra. The study applies psychoanalytic theories, particularly Werman’s (1977) conceptualization of nostalgia as an ambivalent phenomenon comprising cognitive and affective elements. Freud’s theories on mourning and melancholia also provide insights into Achebe’s lamentation over Nigeria’s postcolonial trajectory. This paper argues that nostalgia, as presented in Achebe’s memoir, serves as both a means of mourning and a mechanism of resistance against the dystopian realities of postcolonial Nigeria. The study situates Achebe’s reflections within the broader discourse of postcolonial literature and political history, demonstrating how his narrative engages with the tensions between historical memory, political corruption, and the yearning for an irretrievable utopia.
Terrorization toward Peacebuilding: Dimensions of Direct, Structural and Cultural Means of Violence
Authors: Nazirullah  , Farhat Ullah  , Hayatunnur Azwa Binti Arman
Published: February 2025

The research paper reviewed previous literature on direct, structural, and cultural means of violence in response to disturbing peacebuilding in global societies. This research also answered how direct, structural, and cultural means of violence hamper peacebuilding among global societies. Likewise, what do local states and non-governmental organizations take the initiative to sustain the peace process in society? A documentary research technique was applied to review the previous literature. Research papers on direct, structural, and cultural means of violence were analyzed from different academic websites (“e.g., Google Scholar, academia, PubMed, Scopus, Web of Science”).  The review paper found that the cultural meaning of violence minimizes peacebuilding and puts society in danger. Structural violence increases criminals and decreases peace in society. Direct violence increases the risks of conflict and affects socio-historical coping strategies for peace in society. Cultural meaning supports violent behavior by constructing a framework of culturally related objectives that produce lawbreaking rules for the justice system. In conclusion, direct, structural, and cultural means of violence impact the formation of peaceful norms and behavioral patterns that destroy interpersonal violence and international relations in global societies.

Published: February 2025

Mencuci tangan merupakan salah satu cara untuk menghindari bakteri penyebab infeksi. Mencuci tangan idealnya menggunakan air mengalir selama 20 detik. Namun, seiring bertambahnya kesibukan manusia, penggunaan alkohol sebagai disinfektan pengganti air semakin marak digunakan. Walaupun alkohol terbukti mampu membunuh bakteri penyebab infeksi, alkohol memiliki kekurangan karena memiliki efek samping negatif terhadap manusia. Alkohol dapat menyebabkan iritasi, kulit kering, dan dehidrasi. Untuk mengurangi efek samping dari penggunaan alkohol, dibutuhkan disinfektan berbahan dasar organik yang memiliki efek samping lebih sedikit bagi manusia. Salah satu bahan yang dapat digunakan adalah tanaman kayu putih (Melaleuca leucadendra). Tanaman kayu putih dikenal memiliki senyawa antibakteri terpenoid seperti 1,8-sineol, dan asam organik. Pengambilan bahan kayu putih dilakukan di Lamongan karena kabupaten tersebut memiliki potensi sebagai penghasil kayu putih dengan kualitas yang bagus. Daun tanaman kayu putih yang diolah dengan proses fermentasi memiliki senyawa antibakteri yang bekerja dengan menghambat proses terbentuknya dinding sel pada bakteri. Penelitian ini bertujuan untuk mengetahui efek disinfektan ekoenzim daun kayu putih produksi UMKM Lamongan.Penelitian ini merupakan eksperimen sederhana dengan rancangan komparasi pada setiap konsentrasi ekoenzim. Sampel terdiri dari 3 orang mahasiswa Universitas Airlangga yang dilakukan pengambilan swab bakteri pada jari tangannya.

REPRESENTAÇÕES DA DIVERSIDADE FAMILIAR NA LITERATURA INFANTIL: ENTRAVES E POTENCIALIDADES PARA A ALFABETIZAÇÃO
Authors: Lucas Alves Barbosa e Silva Lucas , De Melo Faria Filho Fausto , Diógenes Dias Silveira Ricardo
Published: February 2025

This study explores how different family structures have been represented in children's literature, aiming to identify and discuss the various forms of family presented in five literary works, as well as to investigate how these representations might influence children's perceptions of family plurality. Methodologically, we conducted a descriptive-exploratory literature review, with an emphasis on content and semiotic analysis. The study discussed how these representations could contribute to literacy and empathy from early childhood, contrasting with the resistance faced in incorporating these themes into the school environment. Based on these analyses, a proposal for an educational product emerged to fill gaps in pedagogical practice and promote a more sensitive education connected to the contemporary realities of children. In this way, children's literature has offered a valuable and inclusive perspective on the multiple family formats, playing a crucial role in children's socio-emotional education.

Published: February 2025

Este artigo objetiva discutir as concepções teórico-metodológicas que atravessam o discurso dos profissionais da educação, professores e gestores escolares, que vêm atuando no Projeto de Implantação da Educação Bilíngue na Rede Pública Municipal de Ensino de Blumenau, o qual vem sendo desenvolvido desde 2019. Trata-se de uma abordagem qualitativa, tendo como instrumentos questionários semiestruturados online e uma atividade de sondagem proposta a esses profissionais durante um curso de formação. Os resultados obtidos sinalizam para um processo de construção de conceitos relevantes no que se refere à Educação Bilíngue de Escolha sob uma perspectiva integrada, e revelam dúvidas a respeito do espaço das línguas no currículo, no cotidiano da sala de aula e no âmbito de cada interação específica. Considera-se, deste modo, que a educação só é bilíngue quando todos os sujeitos que constituem a comunidade escolar compreendem a importância da adoção dessa política educacional e se integram a ela.
OS MECANISMOS DO PRECONCEITO: UM PERCURSO HISTÓRICO
Authors: Mesquita Alexandre , Dal Mas Dias Elaine Teresinha
Published: February 2025

No livro Preconceito: uma História, Leandro Karnal e Luiz Estevam de Oliveira Fernandes investigam as origens históricas e culturais do preconceito e aborda suas diversas manifestações, como misoginia, LGBTfobia, xenofobia, racismo e capacitismo. Os autores demonstram como essas formas de discriminação, construídas socialmente, têm impactado negativamente a vida de indivíduos considerados "diferentes" ao longo do tempo.
          A obra explora os mecanismos que sustentam o preconceito em diferentes contextos históricos e argumenta que, embora essas crenças estejam enraizadas na cultura, elas não resistem a uma análise objetiva e crítica. Por meio de exemplos históricos, os autores ressaltam que o preconceito pode ser desconstruído, uma vez que ele é socialmente aprendido. O livro defende que a educação, o diálogo e a conscientização são essenciais para superar tais práticas e construir uma sociedade mais inclusiva e equitativa.

Design, development and manufacture of a small electric motor dynamometer
Authors: Hong Thong , Truong Phat , Pham Minh , Ho Hoa , Le Hoang , Vu Thang
Published: February 2025

Studying electric vehicle performance, operating range, and control algorithms is still limited in developing countries because it requires specialized equipment, while electric vehicles are increasingly widely used, such as electric cars, electric motorbikes, electric bicycles, etc. This paper introduces the design and manufacture of a small electric motor dynamometer, especially the in-wheel motor. Based on the performance of electric motors and the alternator characteristics, the chain drive was cautiously analyzed and designed to investigate different electric motor speed characteristics over their entire operating range. Especially in this study, the chain drive has three stages with transmission ratios of 1/4, 1/3, and 1/2.5. Besides, a controller that can automatically adjust the electric load level to determine various motor characteristics under constant load and throttle settings is also designed to control the dynamometer and collect essential data. Furthermore, the graphic user interface is built to operate the dynamometer quickly and flexibly. With a flexible transmission ratio and a comprehensive algorithm control, the dynamometer can investigate various characteristics of electric motors used for popular motorbikes and bicycles with power up to 3000W. The designed dynamometer not only has a compact design, stable operation, and affordable price but is also easy to assemble, operate, and maintain. These findings can be applied to develop the dynamometer to investigate the performances of the electric motor and its auxiliary system, serving the research and development process of electric motorbikes used in developing countries today.
Dynamic neural network model for environmental monitoring of vehicle pollution in urban streets
Authors: Shepelev Vladimir , Glushkov Aleksandr , Ivanova Olga , Bastrykina Ksenia
Published: February 2025

The gas pollution of the air by vehicle emissions in a sustainable, smart city is an undeniable and urgent problem that requires new methods of solution. In order to take administrative measures to improve air quality, it is necessary to have a reliable tool for instant assessment of current air pollution at road intersections as places of the largest accumulation of vehicles. This article describes a mathematical model and its software implementation based on neural network technology, which allows continuous monitoring of emissions of nine types of pollutants from various categories of standing and moving vehicles with such parameters as speed, coordinates, and idle time. Authors developed a dataset for the dynamic neural network training, which consists of 60,000 labeled images. The model calculates the pollution level of an air basin in an area determined by the visibility zone of an outdoor video surveillance camera and a height of 2 meters. Unlike existing models, the proposed solution works in real time mode, can be embedded into the existing infrastructure for monitoring road intersections, and takes into account current weather conditions: wind strength and direction. This allowed the authors to verify the results of calculations with instrumental measurements of a mobile environmental laboratory, to achieve high accuracy in detecting current air pollution for further management of environmental risks associated with road traffic.

Tungsten Inert Gas (TIG) cladding is the most promising and feasible technique adopted for the weldability of stainless-steel alloys. In this work, SS 304 fillers were deposited over the SS 316L through the TIG cladding process, and the alloy behavior was studied. The optical study, tensile, and microhardness values of TIG-cladded SS 316L base metal with the SS 304 filler material correlate with the machine learning technique. The Adaptive Neuro-Fuzzy Inference Systems (ANFIS) model is utilized in this study to predict the values theoretically. The correlation between the experimental values and theoretical values is shown to be in good agreement. The enhancement in the mechanical properties of TIG-cladded SS 316L alloy is found to be sounder and more reliable than that of the SS 316L base alloy. The suitable selection of process parameters and the type of cladding (single or double pass) had a significant effect on the improvement of material properties to a greater extent. From the experimental results, the increase in the tensile and microhardness values was found to be 13.2 % and 42.5 %. However, a wide range of methodologies/techniques are available for the theoretical prediction of values, whereas the machine learning technique had a significant effect on the reliable prediction of values. Therefore, it is found that the adoption of machine learning techniques can help flexibly for the identification of a reliable and optimal process parameter in a fabrication process.

The design and fabrication of an on-farm multipurpose cabinet dryer were carried out to address the drying needs of small and medium-scale farmers by providing an efficient, mobile, and sustainable solution for post-harvest processing. The dryer operates with a required air volume of 31.8 m³/min, powered by a blower with a speed of 36,083 rpm, a pressure coefficient of 0.65, and a flow coefficient of 0.69, requiring 162 kW of power input. Heat transfer calculations indicated conduction heat transfer of 21,600 W/m.K, convection at 5.8 x 10⁵ W/m².K, and radiation at 1.85 x 10²¹ W/m², with an overall heat transfer coefficient of 1.85 x 10²¹ W/m².K. The energy source for the dryer is solid fuel, and the design incorporates a lagged drying chamber to minimize heat loss. A fan is mounted on top of the chamber for regulated exhaust of humid air, while solar power operates the fans for energy efficiency. Mobility is enhanced through two wheels, and the blower is connected to the heat exchanger through a frustum-shaped vacuum to ensure even air distribution. Key considerations included the availability of materials, cost, and durability, resulting in an efficient, cost-effective, and sustainable drying solution suitable for on-farm and off-farm operations. This dryer is expected to significantly improve crop drying processes, enhance productivity, and reduce post-harvest losses.
Frequency, Clinical Presentation, and Management of Bartholin's Abscess: A Case Study Conducted at Rabia Balkhi Hospital, Afghanistan in 2022
Authors: Hamidi Hamida
Published: February 2025

Bartholin's gland abscesses are a relatively common gynaecological condition that can lead to significant discomfort and complications if not managed properly. These abscesses typically result from ductal obstruction or infection of the Bartholin glands, causing localized pain, swelling, and erythema. This study evaluated the incidence, clinical presentation, management strategies, and treatment outcomes of Bartholin's gland abscesses at Rabia Balkhi Hospital, Afghanistan, in 2022. A retrospective cohort study used hospital records of women diagnosed with Bartholin's gland abscesses. Twenty-three cases (n = 23) were identified, representing 0.6% of all gynaecological admissions. The most affected age group was 25-35, accounting for 52% of cases. The most common symptoms included severe localized pain (96%), swelling (87%), and erythema (96%). Incision and drainage were the most commonly performed treatment (74%), followed by marsupialization (17%) and drainage tube insertion (9%). The recurrence rate was 13%, and no significant complications were observed. Statistical analysis showed that the highest incidence was in the 25-35-year age group, with a statistically significant association between age and treatment outcomes (p < 0.05). In conclusion, Bartholin's gland abscesses are relatively rare but more common in women aged 25-35. Incision and drainage remain the most effective treatment, with a low recurrence rate. These findings highlight the importance of early diagnosis and intervention to prevent complications. Further studies with larger sample sizes and longer follow-up periods are needed to refine treatment protocols and minimize recurrence rates.
TikTok Narratology, Health Belief System and Sexual Health Awareness among Students of Akwa Ibom State University
Authors: Udoudom Uduak
Published: February 2025

This study investigated the influence of TikTok narratology and students' health belief systems on sexual health awareness among Akwa Ibom State University students. The research utilised the Health Belief Model as its theoretical framework. The study employed a cross-sectional survey design, with a sample size of 370 participants drawn from the population of 10,200 students using the Krejcie and Morgan formula. A structured questionnaire was employed to gather data, which was analysed to determine students' knowledge, perception, and practices regarding reproductive and sexual health information shared on TikTok platform. Findings demonstrated that TikTok increased students' understanding of reproductive and sexual health issues, with many participants finding its content relatable, engaging, and informative. However, participants evaluated content credibility primarily through its alignment with their existing health beliefs. While TikTok campaigns by organisations such as the Society for Family Health (SFH) and the Association for Reproductive and Family Health (ARFH) effectively shaped participants' knowledge, attitudes, and practices, doubt existed when the content contradicted cultural or personal health beliefs. Additionally, the combination of easy accessibility with innovative narrativity enabled TikTok to become an effective health communication channel, but it needed enhancement to adapt sensibly to different cultural belief systems. The study concluded that students' health belief systems determine how effectively TikTok could spread sexual health information, though the platform is a valuable tool for sexual health information dissemination. It is recommended that health educators and campaign organisers develop culturally sensitive and credible content that aligns with student's needs while working with trusted organisations to integrate TikTok into broader health awareness programmes. Communicators were also urged to support digital health campaigns to enhance their reach and impact.
