Abstract Citarum is the longest and largest river in West Java Province. The river which most divides West Java is sourced from the springs of Mount Wayang (south of Bandung), flows north through the Bandung Basin and empties into the Java Sea. At present the Citarum River is one of the polluted rivers in the world. This study aims to provide information on the level of water quality in the Citarum River. The results of this study are expected to provide education to the community to be more concerned about the environment of the Citarum river about river water quality, as well as the impact or treatment of the water for the community. This study designed an information mapping of an observation point using an application based on Geographic Information System (GIS) which can be implemented and applied to an Information dashboard that can be accessed on the website. GIS can provide information about the point of observation of the location of water quality in the Citarum River. It is expected that with the existence of this GIS can provide information on an observation point about water quality in the Citarum River to stakeholders who are accessing the website to find out water quality information.Information dashboards are expected to provide information about the level of water quality to the community or to stakeholders of relevant government agencies to respond and take actions and evaluations. The Information Dashboard is expected to facilitate all stakeholders to monitor and see the water quality in the Citarum River in real-time through the website. With this website, it is expected that it can be easily accessed freely by connecting through the internet network. Keywords: Citarum River, Information Dashboard, Website, GIS, Water Quality.

Abstract

Abstrak Air merupakan salah satu sumber daya alam yang memiliki fungsi sangat penting bagi kehidupan makhluk hidup. Sungai Citarum merupakan sumber air bagi makhluk hidup yang tinggal disekitaran daerah aliran sungai Citarum. Namun, dengan pertumbuhan industri di Indonesia yang semakin pesat, membuat sungai Citarum tercemar akan limbah industri yang dibuang sembarangan ke sungai Citarum. Hal ini membuat kebutuhan air bersih bagi manusia menjadi sulit untuk didapatkan. Dalam memantau kualitas air dan pengendalian pencemaran air, pemerintah masih manual yaitu terjun langsung ke lapangan dalam pengambilan data kualitas air sungai Citarum. Berdasarkan permasalahan tersebut, maka pada penelitian ini ini akan membuat telemetri sensor kualitas air dengan menerapkan protokol Message Queuing Telemetry Transport (MQTT). Dengan adanya telemetri ini, pengambilan data kualitas air menjadi lebih efiesien karena dapat dilakukan dari jarak Protokol MQTT digunakan karena mendukung pada kemampuan yang dimiliki IoT, yaitu dapat berjalan di bandwidth yang kecil sehingga lebih handal dalam mengirimkan data dari sensor dan menerima perintah. Kata kunci: Internet of Things, Telemetri, Kualitas Air, Protokol, MQTT Abstract Water is one of the natural resources that has a very important function for the life of a living collection. The Citarum River is an air source for living things that live around the Citarum river flow. However, with the rapid growth of industry in Indonesia, the Citarum River is polluted with industrial waste which is dumped carelessly into the Citarum River. This makes the need for clean water for humans difficult to obtain. In restoring air quality and controlling air pollution, the government is still manual, which is to go directly to the field to collect water quality data from the Citarum river. Based on these problems, this research will make air quality telemetry sensors using the Message Queuing Telemetry Transport (MQTT) protocol. With this telemetry, taking air quality data becomes more efficient because it can be done from a distance. The MQTT protocol is used because it supports the capabilities possessed by IoT, which can be used on smaller bandwidths can be used in sending data from sensors and receiving requests.

Abstract

In this paper, we surveyed recent publications on topic modeling and analyzed the forms of visualizations and tools used. Expectedly, this information will help Natural Language Processing (NLP) researchers to make better decisions about which types of visualization are appropriate for them and which tools can help them. This could also spark further development of existing visualizations or the emergence of new visualizations if a gap is present. Topic modeling is an NLP technique used to identify topics hidden in a collection of documents. Visualizing these topics permits a faster understanding of the underlying subject matter in terms of its domain. This survey covered publications from 2017 to early 2022. The PRISMA methodology was used to review the publications. One hundred articles were collected, and 42 were found eligible for this study after filtration. Two research questions were formulated. The first question asks, "What are the different forms of visualizations used to display the result of topic modeling?" and the second question is "What visualization software or API is used? From our results, we discovered that different forms of visualizations meet different purposes of their display. We categorized them as maps, networks, evolution-based charts, and others. We also discovered that LDAvis is the most frequently used software/API, followed by the R language packages and D3.js. The primary limitation of this survey is it is not exhaustive. Hence, some eligible publications may not be included.

Abstract

There are growing concerns about security as the usage of computers in academic settings continues to increase. This research aims to investigate the level of awareness among university students regarding security threats associated with ransomware. This study examines students' behaviour and preventive motivation for ransomware attacks, along with the measures taken to mitigate these security threats. The study model combines the theory of planned behaviour (TPB) and preventive motivation theory (PMT) with additional threat awareness (TA) variables. The research findings indicate a high level of awareness regarding the dangers. TA has a positive influence on other factors, as indicated by the significant t-values (perceived severity (PS)=4.479, perceived vulnerability (PV)=3.251, response efficacy (RE)=14.344, and self-efficacy (SE)=8.034). This research also demonstrates that subjective norm (SN) and affective responses (AR) have a key impact on behavioural intention (BI). Moreover, two of the preventive motivation factors, PS and PV, significantly contribute to BI, while the other two (RE and SE) did not show a significant contribution to BI.

Abstract

Augmented Reality (AR) is an innovative technology that has gained significant scholarly attention. It uses computer-generated sensory inputs like visuals, sounds, and touch to enhance how we perceive the real world, providing a transformative impact on human sensory experiences. Motivated by the possibilities of augmented reality (AR) in the realm of the educational learning environment, this research aims to document the evolving landscape of augmented reality (AR) applications in education and training, with a specific emphasis on the incorporation of persuasive system design (PSD) elements. The study also explores the diverse technologies and methodologies for developing these applications. A systematic literature review was conducted, analyzing 44 articles following the protocol for PRISMA assessments. Four research questions were formulated to investigate trends in AR applications. Between 2016 and 2023, publications on AR applications doubled, with a significant focus on the educational field. Marker-based AR methods dominated (68.49%), while markerless methods constituted 31.51%. Unity and Vuforia were the most used platforms, accounting for 77.27% of applications. Most research papers assessed application effectiveness subjectively through custom-made questionnaires. University students were identified as the primary target users of AR applications. Only a few applications integrated persuasive elements, even for adult users. This highlights the need for further studies to fully grasp the possibilities of combining persuasive system design with augmented reality applications in education

Abstract

The global prevalence of type 2 diabetes has escalated in recent decades, prompting an urgent need for effective prevention strategies. Physical activity has emerged as a significant modifiable risk factor for mitigating diabetes risk, yet the precise causal relationship remains a subject of debate, particularly in observational studies. This research leverages advanced causal inference methods to rigorously estimate the effect of physical activity on the risk of developing type 2 diabetes. By employing Propensity Score Matching (PSM), we address confounding biases inherent in observational data, ensuring more reliable estimates of treatment effects. Additionally, we integrate machine learning techniques, including causal forests, to explore heterogeneous treatment effects (HTEs) across different population subgroups. Our findings highlight that the benefits of physical activity in reducing diabetes risk are not uniform but are more pronounced among individuals with higher body mass index (BMI), further underlining the necessity of tailored interventions. The application of advanced causal inference models allows us to account for confounders such as diet, socioeconomic status, and pre-existing health conditions, offering a more comprehensive understanding of the relationship between physical activity and diabetes prevention. This study contributes to the growing literature by demonstrating that physical activity significantly reduces diabetes risk, with particular benefits for high-risk subgroups. Our findings provide evidence for public health policies that emphasize physical activity as a cornerstone of diabetes prevention, promoting individualized approaches to intervention.
