Abstract

Dengue Fever is a significant and recurring public health challenge in tropical urban centers, including the city of Surakarta, Indonesia. The transmission of this vector-borne disease is highly sensitive to local climatic conditions, as high rainfall and humidity create ideal environments for the proliferation of the Aedes aegypti mosquito. This study aims to analyze the epidemiological trends of Dengue Fever in Surakarta from 2021 to 2023 and to determine the influence of key environmental factors on disease transmission dynamics. A descriptive epidemiological study was conducted using secondary data on reported Dengue Fever cases across Surakarta's five sub-districts: Laweyan, Serengan, Pasar Kliwon, Jebres, and Banjarsari. Incidence rates per 100,000 population were calculated and correlated with monthly rainfall and humidity data. The results showed significant fluctuations in incidence, with a major surge in 2022, when 166 total cases were recorded. The district of Laweyan recorded the highest incidence rate that year at 134.59 cases per 100,000 population. This peak strongly correlated with high rainfall and humidity during the first quarter of 2022, which provided optimal mosquito breeding conditions. In contrast, 2021 had the lowest incidence amid drier conditions. These findings confirm a strong association between climatic factors and Dengue Fever transmission in Surakarta. High rainfall and humidity are critical contributors to the disease burden, underscoring the urgent need for integrated, climate-based forecasting within public health surveillance systems to mitigate future outbreaks effectively.

Abstract

The rapid development of digital technology requires the improvement of students’ digital literacy, particularly in Informatics education. Digital literacy goes beyond the ability to operate technological devices, encompassing critical thinking, collaboration, and understanding of digital ethics. To support these competencies, interactive learning media relevant to students’ digital context are essential. GlideApps, a no-code web-based application platform, provides an innovative solution that enables teachers and students to independently develop interactive learning media. This study aims to analyze the role of GlideApps in enhancing students’ digital literacy in Informatics subjects. The research employs a Systematic Literature Review (SLR) of national and international studies published between 2018 and 2024. The findings reveal that GlideApps promotes student engagement, supports project-based learning, and simplifies application development without requiring programming skills. Moreover, it fosters students’ understanding of computational thinking and the ethical use of digital technology. However, challenges remain, including limited teacher training, unequal infrastructure, and the scarcity of specific research on GlideApps’ impact on digital literacy dimensions. The study concludes that GlideApps holds significant potential as an interactive learning medium to strengthen digital literacy, while recommending further context-based and in-depth research.

Abstract

Slow pyrolysis is a biomass conversion method commonly used on a laboratory scale. This process takes place in a reactor and uses LPG gas as a heating source. In addition to the pyrolysis reactor design, the reactor configuration and operational conditions affect the amount and characteristics of the final product produced. This pyrolysis process is affected by several operational conditions, namely particle size, heating rate, temperature, and carbonization time. This study aims to observe the temperature distribution in a fixed-bed pyrolysis reactor made of stainless steel using three different types of biomass: rice straw, corn cobs, and peanut shells. Temperature distribution observations were carried out at three vertical points: at the bottom of the reactor (T1), the center of the reactor at a height of 15 cm (T2), and the surface at a height of 30 cm (T3). The results of the study showed that the temperature distribution in a fixed-bed cylindrical pyrolysis reactor with dimensions of 42 cm in diameter, 55 cm in height, without insulation without a stirrer, and made of stainless steel showed an uneven temperature distribution from the point at the bottom of the reactor (T1), in the middle of the reactor (T2) and on the surface of the biomass (T3). The temperature difference at the observation points T1, T2, and T3 occurred in both rice straw, peanut shells, and corn cobs. The uneven temperature distribution in the pyrolysis reactor was caused by several things, including the reactor design not supporting uniform heat distribution, the characteristics of agricultural waste biomass, the absence of biomass stirring, so that the biomass remained still (steady) and heat did not spread homogeneously even though the biomass had been given pre-treatment such as uniform size and reduction of water content through heating. To prevent temperature differences, the addition of a jacket to the reactor design could maintain even heat circulation around the reactor and reduce heat transfer from the reactor directly to the environment.

Abstract

The economic transformation from extractive industries to tourism presents complex challenges for post-mining regions, requiring leadership that is visionary, collaborative, adaptive, and rooted in local values. This research examines integrative leadership's role in facilitating economic transition from tin mining to sustainable community-based tourism in Belitung Regency, Indonesia. Using qualitative multi-case methodology across nine villages with diverse socio-economic and geographic contexts, data were collected through in-depth interviews, participatory observation, focus group discussions, and document analysis. Thematic analysis supported by triangulation, member checking, and audit trails revealed that integrative leadership plays crucial roles in shaping collective visions, strengthening local institutions, and mobilizing community participation. Local leaders employed educational, participatory, and collaborative strategies addressing key challenges including social resistance, limited human capital, and mining legacy dependency. The transformation yielded increased household income, economic diversification, and cultural identity revitalization, though impacts varied significantly across villages. Tourism sustainability in these post-mining communities depends critically on leadership quality, institutional capacity, and ecological awareness. This study contributes to integrative leadership theory development within post-extractive economic contexts and offers practical insights for policymakers and stakeholders promoting inclusive sustainable tourism transitions.

Abstract

Ecotourism in East Kalimantan holds significant potential as a sustainable tourism model that not only preserves the natural environment but also enhances the welfare of local communities. However, challenges such as low tourist loyalty, limited accessibility, inadequate facilities, and less effective promotion continue to hinder its development. This study aims to formulate strategies for building tourist loyalty in ecotourism by applying Importance Performance Map Analysis (IPMA), which emphasizes variables with high influence but low performance. A mixed-methods approach was employed. Quantitative data were collected from 170 ecotourism visitors and analyzed using Structural Equation Modeling–Partial Least Square (SEM-PLS), followed by IPMA mapping. Qualitative analysis was conducted through a review of tourism policies and regulations. The variables examined include Place, Findable, Fulfilling, attitude, promotion, interest, and subjective norms. The findings reveal that Place is the most important factor influencing loyalty, but its performance is low, particularly in terms of destination accessibility. Tourist interest plays a crucial moderating role, strengthening the effect of subjective norms and destination quality on loyalty, meaning that higher interest leads to greater likelihood of repeat visits. Subjective norms show relatively weak influence but can be improved through community-based strategies, visitor testimonials, and the use of local influencers. Furthermore, Findable and promotion contribute to strengthening loyalty by expanding digital information reach, while fulfilling and attitude require improvement through consistent tourist experiences and responsive service. Overall, the development of ecotourism in East Kalimantan cannot rely solely on natural attractions but requires a holistic strategy encompassing infrastructure improvement, digital promotion optimization, educational campaigns on ecotourism benefits, and active community involvement. Such an approach is expected to increase tourist satisfaction, foster long-term loyalty, and simultaneously support nature conservation and local cultural sustainability.

Abstract

Indonesia is renowned for being a country rich in culture, one aspect of which is reflected in the diverse traditional houses found across its regions. Unfortunately, younger generations are becoming less familiar with this heritage due to monotonous and theoretical approaches in formal education. To address this issue, this study aims to develop an Android-based educational game that utilizes a drag-and-drop concept to introduce Indonesia’s traditional houses interactively. The game development process follows the Game Development Life Cycle (GDLC), consisting of six main stages: initiation, pre-production, production, testing (black box), beta testing, and release. Data were collected through a literature review of traditional houses, the GDLC method, and educational game development techniques. The resulting game, titled "Kiddo Match It! Traditional Houses," features an interactive map of Indonesia, an encyclopedia of traditional houses, a series of levels based on geographic regions, and a gameplay mechanic that involves matching images of traditional houses with their names. All stages of GDLC were implemented with a focus on visually engaging design and user-friendly navigation, specifically for users aged 8–15 years. Black box testing showed that most features functioned as intended, while beta testing indicated a user satisfaction rate of 91%, categorized as “Very Good.” This study produced a digital learning medium that introduces 34 traditional houses from all Indonesia provinces through a visual and interactive approach, making it a relevant educational tool for cultural preservation in today’s digital era.

Abstract

More than half of the mental health problems that impact one-third of individuals with diabetes mellitus go undiagnosed. Stress has an effect on physical health in addition to upsetting the mind. Distorse is e-learning about respondents' mental health and e-health in the form of mobile health (which includes apps, technology, and health resources).The early diagnosis approach for depressed conditions experienced by individuals with diabetes mellitus undergoing treatment has been modernized with the Sobat Antasari method. The purpose of this study is to keep people with diabetes mellitus mentally healthy and lower their depression levels. The 66 respondents in this quasi-experimental study were split into two (two) groups using proportional random sampling, and the study included a pretest-posttest design with a control group. The depression anxiety stress scales (DASS), an internationally validated questionnaire, are the instrument utilized in this study. With a p-value of 0.036, the study's findings demonstrated that the Early Detection of Fatality Caused by Diabetes Mellitus intervention group was impacted by efforts to employ Distorse media. This demonstrates that the degree of depression before and after the use of book media and Distorse applications differs significantly. However, with a p-value of 0.299>0.05, the control group, which received simply mental health book media, did not show any significant evaluation outcomes. The combination intervention of book media and Distorse applications has been shown to be effective in significantly lowering the level of depression in patients with diabetes mellitus.

Abstract

— Digital transformation in the education sector requires institutions to adopt web-based information systems that serve as the backbone of academic and administrative operations. While these platforms improve efficiency and accessibility, they also introduce a growing number of cyber threats that may compromise the confidentiality, integrity, and availability of institutional data. This study seeks to identify, analyze, and prioritize information security risks associated with web-based systems at SMKN 7 Tangerang Regency. The research adopts the NIST SP 800-30 framework as the methodological foundation for risk assessment, ensuring a systematic and comprehensive evaluation process. A quantitative approach was implemented by distributing questionnaires to key stakeholders, including administrators, IT staff, and teachers, in order to capture diverse perspectives on vulnerabilities and threats. The results revealed 15 significant risk factors spanning governance, operational, and technical domains. Among these, the absence of a formal information security policy, the lack of data encryption mechanisms, and the absence of continuous monitoring systems were identified as the highest-priority risks, each reaching a risk score of 12. To address these challenges, the study recommends the development of structured mitigation strategies, such as formulating security policies, implementing encryption protocols, and establishing proactive monitoring tools. The contribution of this research lies in producing a scalable risk assessment model that can be applied to other educational institutions. By doing so, it provides practical guidance for decision-makers and educators in creating a more secure, resilient, and trustworthy digital learning environment.
