Airflow Simulation

We present engineering airflow to intercept the transmission of Covid19 in public spaces and public transportations, which relatively fast and simple. This technique is to suppress effectively and as massive as possible the spread of aerosols and droplets contaminated with the COVID-19 virus that is flying in the air by providing a vertical downward flow using fans placed on the ceilings and the use of floors of the certain material so that aerosol and microdroplets will not bounce back up, difficult to roll, and firmly attached to the floor. The numerical airflow simulation shows that positioning the fan on the ceiling of the room will cause the air particle to move faster downward, which will push the microdroplets to fall to the floor more quickly, so that the microdroplets and aerosols will quickly move away from the most risk organs from the transmission, namely the mouth and nose. The contactangle test results on several floor materials always show a value of fewer than 90 degrees. These phenomena cause microdroplets or aerosols that fall to the floor will stick tightly and not easily roll. This phenomenon will cause the room to be more sterile from aerosols and microdroplets that may be contaminated with Covid19. The room will be healthier and safer. This technique can be a solution that is relatively inexpensive and simple to implement on a field scale and is very effective in reducing the radius of the spread of droplets or aerosols in closed spaces, both public spaces and public transportation, such as trains and city buses which are very susceptible to Covid19 transmission.

The background of this study aims to see the response of people in Semarang regency by the policy of mass transportation agglomeration Bus Rapid Transit (BRT). Data collected through literature study, questionnaires, direct observation and documentation. Data analysis technique is descriptive percentage. The results show some of the public response with public transportation angkot / bus 55% community response still does not accelerate travel time. As many as 94% of people in Semarang Regency are very interested and much needed by the development of mass transportation based on Bus Rapid Transit (BRT). As many as 88% of the people in Semarang district need cheap transportation, safe and convenient. The public prefers BRT mass transportation as opposed to using Private vehicles by 54%. Most of them with 52% of people in Semarang regency do not know the route of BRT to be passed from Semarang (Tawang) - Semarang Regency (Bawen). Suggestion for Central Java government to carry out mass transit Bus Rapid Transit (BRT) connected with Semarang City which bertrayek in Semarang Regency (Bawen) - Semarang City (Tawang). The government also evaluates the location of shelters that feed on street users. Latar belakang penelitian ini bertujuan untuk melihat respon masyarakat di Kabupaten Semarang dengan adanya Kebijakan Aglomerasi transportasi massal Bus Rapid Transit (BRT).

Key Factor

With the spread of the coronavirus worldwide, nations have implemented policies restricting the movement of people to minimize the possibility of infection. Although voluntary restriction is a key factor in reducing mobility, it has only been emphasized in terms of the effect of governments’ mobility restriction measures. This research aimed to analyze voluntary mass transportation use after the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak by age group to explore how the perception of the risk of infection affected the public transit system. Mass transportation big data of Seoul Metro transportation use in the capital city of Korea was employed for panel analyses. The analysis results showed that in the period with both the highest and lowest number of infections of SARS-CoV-2, users aged 65 years and over reduced their subway use more than people aged between 20 and 64. This study also found that the decrease in subway use caused by the sharp increase of coronavirus disease 2019 (COVID-19) cases was the most prominent among people aged 65 years and over. The results imply that the elders’ avoidance of public transportation affected their daily lives, consumption, and production activities, as well as their mobility.

The goal of this study was to ascertain the critical nature of public transportation under the supervision of a health protocol. During the COVID-19 pandemic's New Normal phase, the government issued an appeal addressing health procedures for individuals who are active in public spaces or who use public facilities. This protocol also applies to the public transportation industry, specifically the bus industry. Health rules for bus use must be strictly adhered to and monitored in order to prevent the virus from spreading. The health protocol is implemented to offer a sense of security for public bus riders without jeopardizing the quality of service. A series of laws limiting capacity and enforcing strict adherence to health protocols for all modes of public transportation

Some coastal communities still have the habit of defecating in open areas such as on the beach or in the garden. That is because the public does not yet know about the poor behavior related to sanitation that will affect the quality of other public health. The purpose of this study is to apply the Antecedent Behavior Consequences chain method for modification of Open Defecation behavior in child targets.  This research is a quantitative study using quasy experiment design with time series design. The population is all class IV-VI at SDN Tamalate who still defecate carelessly. A sample of 37 students. The sampling technique in this study was exhaustive sampling. Data analysis using t-dependent test, Mc. Nemar and chi square with a significant level of 0.05. The results of this study indicate that there is a difference in intention score with the statistical test results of 98.18%, with a  knowledge score of 10.8%  to 100%, the action score from never defecated by 0.0% to 86.5% with a value p=0,000. While those who have utilized the facilities amounted to 97.3%. Suggestions for the government, should collaborate with schools and health centers to replicate or implement learning while playing with the method of snakes and ladders in providing education, about stopping open defecation in children.

At this time, information is very easy to obtain, information can spread quickly to all corners of society. However, the information that spreaded are not all true, there is false information or what is commonly called hoax which of course is also easily spread by the public, the public only thinks that all the information circulating on the internet is true. From every news published on the internet, it cannot be known directly that the news is a hoax or valid one. The test uses 740 random contents / issue data that has been verified by an institution, where 370 contents are hoaxes and 370 contents are valid. The test uses the K-Nearest Neighbor algorithm, before the classification process is performed, the preprocessing stage is performed first and uses the TF-IDF equation to get the weight of each feature, then classified using K-Nearest Neighbor and the test results is evaluated using 10-Fold Cross Validation. The test uses the k value with a value of 2 to 10. The optimal use of the k value in the implementation is obtained at a value of k = 4 with precision, recall, and F-Measure results of 0.764856, 0.757583, and 0.751944 respectively and an accuracy of 75.4%

Transportation Routes

Traffic congestion problems generally caused by the increasing use of private vehicles and public transportations. In order to overcome the situation, the optimization of public transportation’s route is required particularly the urban transportation. In this research, the performance analysis of Firefly and Tabu Search algorithm is conducted to optimize eleven public transportation’s routes in Bandung. This optimization aims to increase the dispersion of public transportation’s route by expanding the scope of route that are crossed by public transportation so that it can reach the entire Bandung city and increase the driver’s income by providing the passengers easier access to public transportations in order to get to their destinations. The optimal route is represented by the route with most roads and highest number of incomes. In this research, the comparison results between the reference route and the public transportation’s optimized route increasing the dispersion of public transportation’s route to 60,58% and increasing the driver’s income to 20,03%.
