Determinants of PM2.5 Concentration in DKI Jakarta Province: A VAR Model Approach
Get PDFAir pollution in the DKI Jakarta Province is a serious issue as it is related to public health and environmental concerns. Therefore, this research aims to analyze the causality of PM2.5 concentration with meteorological factors such as air temperature, humidity, rainfall, and wind speed. The data source used is from the MERRA-2 satellite, which provides information at a spatial resolution of 0.5° × 0.625°. The data covers the period from January 1, 1980, to November 1, 2023, with hourly time intervals. The research variables involve PM2.5 concentration as the response variable, as well as predictor variables such as air temperature, humidity, rainfall, and wind speed. The analytical method employed is the Vector Autoregressive (VAR) approach, as all variables are stationary at the level. The constructed VAR model tends to indicate that meteorological variables have a low explanatory power for PM2.5 concentration, while changes in PM2.5 concentration itself have sustained impacts in both the short and long term. This suggests that the fluctuations in PM2.5 concentration in DKI Jakarta Province are not significantly influenced by meteorological factors
Determination of the Composition of Fly Ash, Bottom Ash and Lime or Cement Mixtures as Road Base Material. Case Study: Road Preservation of Sp. Kereng - Bereng Bengkel – Pilang – Pulang Pisau, Central Kalimantan
Get PDFAggregate material for road subbase layers that meet specifications is hard to find in Kalimantan Island. One alternative material is a mixture of fly ash and bottom ash (FABA) with the addition of other substances such as lime or cement as binders. It is essential to determine the optimum percentage of the fly ash, bottom ash, and lime or cement mixture to meet the requirements as road subbase material. This study was conducted by creating compositions of FABA with variations 100:0; 75:25; 50:50; 25:75; and 0:100; they were tested to determine the optimum mixture of FABA as a road subbase. Afterwards, additional materials that were cement (3%, 5%, and 7%) or lime (2%, 4%, and 6%) were added to the optimum mixture of FABA; and then, they were tested to obtain the subbase material that meets the requirement of Bina Marga specification criteria. The results show that the optimum FABA material mixture is 50:50 which has the soaked CBR value of 17.03%. Additional 7% of cement or 6% of lime give the highest values of soaked CBR and UCS. For cement, the soaked CBR value is 75.68% and the UCS value is 21.448 kg/cm2; for lime, the soaked CBR value is 60.16% and the UCS value is 27.70 kg/cm2. Based on Bina Marga specifications, SKh 1.15.1, it is known that the FABA mixture 50:50 ratio and the additional of 7% cement or 4% lime can be uses as road base materials

Understanding the Factors that Influence Digital Readiness in Education: A UTAUT Study among Digital Training Learners
Get PDFDigital transformation is a critical element in modern business operations. Yet, more research needs to be conducted from the perspective of individuals responsible for implementing DT initiatives in their daily work, such as faculty and staff. This study investigates the relationship between digital readiness in education and the constructs outlined in the Unified Theory of Acceptance and Use of Technology (UTAUT) model. We employed a purposive, non-probabilistic sampling strategy to gather data, resulting in 165 observations. The experimental results indicate a significant positive relationship between behavioral intention to adopt digital trans- formation and the behavior of applying digital transformation at work, perceived effectiveness of digi- tal transformation adoption, and facilitating conditions, all in line with the UTAUT model. However, we did not find a significant relationship between effort expectancy or social influence and behavioral intention to adopt dig- ital transformation. Under- standing the factors that impact digital readiness enables universities to develop targeted interventions and support services to promote the successful implementa- tion of DT initiatives in education
Elementary Algorithmic Methods for Solving Suguru Puzzles
Get PDFWe discuss elementary algorithmic aspects of the Suguru puzzle---a single-player paper-and-pencil puzzle introduced in 2001 and confirmed NP-complete in 2022. We propose a backtracking algorithm with pruning optimizations for solving an Suguru puzzles containing regions and hint cells in time. Despite this factorial asymptotic upper bound, a C++ implementation of our proposed algorithm successfully solved all Suguru instances with no more than cells using a personal computer in less than second. We also prove that any Suguru instance of size with either or can be solved in linear time in terms of the puzzle size. Finally, we provide an upper bound for the number of solutions to such tractable instances
Effect of Rainfall on Digital/Analog Television Signals
Get PDFRainfall has a strong negative impact on television (TV) signals, most especially at the receivers’ end. This is due to the propagation effect caused by atmospheric rain absorption of the wave signal. Television signals may reach the TV receiver unstable due to interferences caused by heavy rainfall, which creates undesirable poor-quality reception and noise. The effect of rain-induced attenuation on television signal reception is not enviable, especially when it is heavy. Consequently, this work aims to analyze the correlation between received signal strength and frequency of transmission during rainfall. The received signal strength measurements and rainfall data were collected concurrently during dry days and rainy days to achieve this aim. These readings were taken with a signal strength meter and other mobile phone software such as the rain gauge app, compass, etc.). Results show that rainfall leads to a noticeable degradation in the quality of received signals. Specifically, the data obtained were simulated, and it was observed that attenuations increase sharply as the rain rate increases. In particular, when the frequency is about 1080 GHz and the wavelength is low, there tends to be a disturbance between the drops of rainfall, which causes attenuation and results in low signal strength. To conclude, this work proposes a possible solution that is favorable to all television subscribers during rainfall
The Effect of Cabbage Waste Pretreatment on Lignocellulose Content for Bioethanol Production
Get PDFCabbage waste represents a resource rich in lignocellulose, offering substantial potential as a raw material for bioethanol production. However, the nature of lignocellulosic complexes necessitates effective pretreatment strategies to enhance cellulose accessibility. This study aims to determine the effect of pretreatment on cabbage waste on changes in lignocellulosic content before and after pre-treatment to determine the influence of solution concentration and pretreatment duration of cabbage waste on the level of reducing sugars, which will subsequently affect bioethanol fermentation. In this research, cabbage waste was pretreated using H2SO4 1 M and alkaline NaOH 1 M for 1 hour to determine the pretreatment agent that produced the highest cellulose content. Furthermore, the concentration (1 M; 1.5 M; 2 M) and the pretreatment time (1 hour; 1.5 hours; 2 hours) will be varied to produce the highest reducing sugar content, which will be continued to the Simultaneous Saccharification and Fermentation (SSF). The results showed that pretreatment using H2SO4 produced the highest change in cellulose content. Pre-treatment using H2SO4 at a concentration of 1.5 M for 1.5 hours produced the highest reducing sugar concentration of 0.32 g/L. The highest bioethanol content was obtained during fermentation for 72 hours at 22.25%
Pengaruh Fear of Missing Out (FOMO) dan Social Media Marketing terhadap Niat Pembelian pada Produk Healthy
Get PDFThe food and beverage industry in Indonesia has stimulated a surge in Indonesian youth's practice of consuming nutritious food, resulting in fierce rivalry among enterprises in the healthy food sector. In order to manage the highly competitive business environment, organizations have increasingly resorted to utilizing social media marketing as a means to increase consumer inclination to make purchases. However, the widespread use of social media has led to concerns about individuals feeling excluded or perceived as outdated, a phenomenon commonly known as Fear of Missing Out (FOMO). The objective of this study is to examine the influence of Fear of Missing Out (FOMO) through social media marketing on consumers' inclination to make a purchase. We administered a survey using Google Forms to 120 participants aged between 18 and 34. We then analyzed the collected data using partial least squares structural equation modeling (PLS-SEM). The results indicate that both the fear of missing out (FOMO) and social media marketing have a beneficial impact on the desire to purchase healthy food goods. Utilizing the fear of missing out (FOMO) in social media marketing techniques can successfully enhance consumer attention and stimulate sales in the healthy food industry
