Pediatric Electrical Bicycle Road Accidents

Introduction The use of electric bicycles (EBs) among children younger than 18 years of age is rapidly increasing worldwide and becoming a substantial contributor to road accidents. We analyzed patterns and severity of pediatric bicycle-related injuries, comparing children riding EBs and classic bicycles (CBs). Materials and Methods This was a retrospective study (January 2016–December 2018) of patients arriving at our medical center due to a bicycle accident. Data were collected from medical records and included demographics, injury characteristics, treatment, and outcomes. Results Of 561 children, 197 (35%) were EB riders and 364 (65%) were CB riders. Injury severity score (ISS) of EB cyclists was significantly higher than CB cyclists (mean 4.08 ± 4.67 and 3.16 ± 2.84, respectively, p = 0.012). The rate of accidents involving motorized vehicles was higher in the EB versus CB group (25.9 vs. 11.3%, p < 0.001). Head injuries were the most common type of injury in both groups; incidence was higher in CB than in EB cyclists. However, loss of consciousness was more common in the EB group (18.3 and 12.1%, respectively, p = 0.057). Lower extremity injuries were more common in EBs versus CBs (55.8 and 37.6%, respectively, p < 0.001). Orthopaedic surgical interventions were significantly higher in the EB group (49.2 vs. 33.2%, p < 0.001), and length of stay in hospital and admission to pediatric intensive care unit were more common in EB compared with CB, although not significantly. Conclusion Injury severity of EB patients was significantly higher than that of CB patients. Accidents involving motorized vehicles were more common in the EB group. Head injury associated with loss of consciousness was significantly higher in EB patients.

PERFORMANCE OF THREE ARMS SIGNALIZED INTERSECTION AT SALABENDA IN BOGOR REGENCY

<p>The increase in urban transportation in the 2000s era was very high. The use of motorized vehicles during the pandemic has decreased slightly with the government's ban on traveling out of town, including the 2020 homecoming and 2021 homecoming. Most people who travel are in the city center, including the city of Bogor and Bogor district. The travel patterns are very diverse, but most use public transportation and private transportation in addition to freight transportation with a fairly high intensity, especially at night. The purpose of this study was to obtain the LoS value at the signalized intersection of the three arms of the Salabenda intersection. The three-arm Salabenda intersection is the border between Bogor regency and the city of Bogor, so this intersection is one of the busiest and most densely populated intersections beside the Ciawi intersection in the north. The Salabenda intersection has become more congested with the opening of the Section IIIA Toll Road so that the traffic load shifts from Jl. KH. Sholeh Iskandar to this toll road, so that the intersection will have a higher traffic intensity. From the three observations and data collection in the field, it can be seen that in the afternoon it has a very high LoS, namely E. Followed by a LoS D level in the afternoon and in the morning LoS is still in the form of C. So it is still safe to use in the morning with a recommended level. The LoS E condition is a condition where the intersection has a degree of saturation of 0.926, which is almost close to 1, exacerbated by high side resistance activity.</p>

TRAFFIC DENSITY DUE TO MOTORCYCLE NOISE DURING THE PANDEMIC COVID-19

<p>The density of motorized vehicles, especially motorcycles on the highway, is getting higher. However, in line with the 2020 Covid-19 pandemic, it has an impact on the decrease in the number of motorized vehicles on the highway. The density of motorcycles has a significant effect on noise, from all analysis calculations, the largest equation is obtained on the fourth day of the study, the second point (Sound Level Meter 2), with a contribution of 32.42%. Obtained the calculation below, y = 63.36 + 0.002x1. This equation means that if there is no decrease in motorcycle density, the noise level in SLM2 is 63.36 dBA. If there is a motorcycle density also has a significant effect on noise. The second largest equation was obtained on the third day of research at the third point (Sound Level Meter 3) with a contribution of 36.21% based on the equation calculation below, y = 60.24 + 0.001x1. The meaning of the above equation is that if there is an increase in the density of the motorcycle, the noise in the SLM3 is 60.24 dBA. The Covid-19 pandemic that has hit the world, Indonesia is also getting its effects, especially the very large Bogor district. The rapid spread of Covid-19 has changed the pattern of life for the people of Bogor, especially students who initially go to school every morning, now go to school and study online.</p>

Carbon Dioxide (CO2) Emissions Due to Motor Vehicle Movements in Pekanbaru City, Indonesia

Land use has a very close relationship with transportation. Transportation is formed as a result of the interaction between land use and its support system. Good land use supported by good infrastructure will result in good movement as well. Accessibility is one of the supporting factors for good interaction between transportation and land use—the better the land use conditions in an area, the greater the movement in that area. However, the interaction between land use and transportation can cause one of the problems: the increase in carbon dioxide emissions due to the more significant movement of motorized vehicles. Motor vehicles are the most significant contributor to carbon dioxide (CO2) emissions in the world. The further the route traveled by motorized vehicles, the more carbon dioxide (CO2) emissions will increase. This study aims to analyze the average total emission of carbon dioxide (CO2) resulting from transportation activities in Pekanbaru City into two parts, namely: (1) Based on Travel Time (2) Based on the type of vehicle. Vehicle Kilometers of Travel (VKT) and Emission Factors are the primary data in calculating Carbon Dioxide (CO2) Emissions. The research area consists of 12 zones involving 1,342 households in Pekanbaru City. Based on travel time, 52% of community motorized vehicle movement activities are carried out in the morning. Private cars contribute 65% of carbon dioxide (CO2) emissions in Pekanbaru City based on the type of vehicle. This study found that a high number of motorized vehicles cannot be used as a benchmark that the resulting emissions will also be high. However, the emission of carbon dioxide (CO2) depends on the fuel consumption of each vehicle. The higher the fuel consumption, the higher the amount of carbon dioxide (CO2) emissions released by motorized vehicles.

Android Based Tire Patch Search

The number of motorized vehicles continues to increase, this will be directly proportional to the number of people who experience motorcycle damage when driving on the highway, such as leaking tires or burst tires. For motorists who do not know the surrounding area when a motorcycle tire is damaged, of course it will be difficult to find the nearest tire patch. In this study, an Android application will be developed to map and find the location of motorcycle tire patches in Bukit Raya District. This application will provide location-based services to users. With this application, users will get information in the form of a map showing the location of the nearest tire patch. Based on the test results, the tire patch location mapping application that was built is able to display the locations of the tire patches along with information on the travel route from the user's location to the nearest selected tire patch location. This application was developed on the Android operating system because Android provides an open platform for developers to create their own applications and Android is one of the operating systems that are widely used by smartphones that are growing rapidly now. This application is expected to help users who want to find the location of the tire patch along with information from the tire patch and the closest route to the tire patch location so that it is more efficient in terms of time

PERAN RESPIRATOR DALAM PENCEGAHAN DAMPAK KESEHATAN AKIBAT POLUSI UDARA (STUDI KASUS DESA KLARI)

ABSTRAKPeran Respirator Dalam Pencegahan Dampak Kesehatan Akibat Polusi Udara Di Desa Klari, Kecamatan Klari, Kabupaten Karawang. Kegiatan ini di latar belakangi Desa Klari yang memerlukan perhatian terhadap peran respirator akibat dampak dari polusi udara. Selain itu, diharapkan dengan adanya Kegiatan Kuliah Kerja Nyata (KKN) ini dapat membantu masyarakat dalam meningkatkan kesadaran masyarakat akan pentingnya dampak polusi udara bagi Kesehatan di Desa Klari Kecamatan Klari. Hal ini dilakukan dengan cara menanyakan serta membagikan kuisioner ke masyarakat Desa Klari dengan adanya peran respirator bagi dampak Kesehatan akibat polusi udara. Dengan tingkat kesadaran masyarakat yang masih minim terhadap pentingnya peran respirator terhadap Kesehatan akibat polusi udara. Hal ini didasari dengan kondisi polusi udara di Desa Klari yang terbilang tidak terlalu baik akibat adanya polusi dari banyaknya kendaraan bermotor, asap pabrik, dan kegiatan pembakaran yang sembarangan. Dengan adanya kegiatan KKN di Desa Klari diharapkan tidak hanya dalam peningkatan peran respirator bagi masyarakat Klari tapi dihimbau bagaimana cara menanggulangi polusi udara dengan cara menanam pohon yang mengandung daya serap gas karbondioksida (CO2) dan pembuatan tong sampah guna mengurangi tingkat volume sampah di lingkungan Desa Klari. Kata Kunci: respirator; polusi; karbondioksida (CO2); desa klari; volume. ABSTRACTThe Role of Respirators in Preventing Health Impacts Due to Air Pollution in Klari Village, Klari District, Karawang Regency. This activity is in the background of Klari Village which requires attention to the role of respirators due to the impact of air pollution. In addition, it is hoped that this Real Work Lecture (KKN) activity can help the community in increasing public awareness of the importance of the impact of air pollution on health in Klari Village, Klari District.This is done by asking and distributing questionnaires to the Klari Village community with the role of respirators for health impacts due to air pollution. With the level of public awareness that is still minimal on the importance of the role of respirators on health due to air pollution. This is based on the condition of air pollution in Klari Village which is not very good due to pollution from many motorized vehicles, factory smoke, and indiscriminate burning activities.With the KKN activities in Klari Village, it is expected not only to increase the role of respirators for the Klari community but are also encouraged to overcome air pollution by planting trees that contain carbon dioxide gas absorption (CO2) and making trash cans to reduce the level of waste volume in the Klari Village environment. .

PERENCANAAN PENGEMBANGAN RUANG TERBUKA HIJAU SEBAGAI AREA PUBLIK

When discussing Green Open Space (RTH), of course its existence is something that is underestimated by most people even by the district/city government. This is because the mindset of the community and the government that considers the development of Green Open Spaces is not too important is carried out because of the lack of feedback provided by Green Open Spaces to the community and government so that the land of a Regency / City area is overcrowded by other infrastructure developments plus other with the increase in population, resulting in the need for new Green Open Spaces in their minds. The research method used is a qualitative approach with data collection techniques through literature or literature studies.This was only realized because of the community's need for a place to release the fatigue that afflicts due to the many demands from work, the worsening of air quality in a Regency/City area as a result of the rise of industry and motorized vehicles which make the air increasingly polluted by air pollution, and also the lack of land for accommodate water when it rains which makes many areas flooded when it rains because of the lack of water catchment areas. Keywords: Development Planning; Green Open Space; Regulation AbstrakBila membahas Ruang Terbuka Hijau (RTH) tentunya keberadaannya bagaikan sesuatu yang dianggap remeh oleh kebanyakan orang bahkan oleh pemerintah kabupaten/kota. Hal ini dikarenakan pola pikir dari masyarakat dan pemernitah yang menganggap pembangunan Ruang Terbuka Hijau tidaklah terlalu penting itu dillakukan karena kurangnya input balik yang diberikan oleh Ruang Terbuka Hijau kepada masyarakat maupun pemerintahan sehingga membuat lahan dari suatu wilayah Kabupaten/Kota penuh sesak oleh pembangunan infrastruktur lainnya ditambah pula dengan bertambahnya jumlah penduduk sehingga mengakibatkan kebutuhan akan Ruang Terbuka Hijau baru terpikirkan oleh mereka.Metode penelitian yang digunakan adalah pendekatan kualitatif dengan teknik pengumpulan data melalui studi literatur atau kepustakaan. Hal ini baru disadari karena kebutuhan masyarakat akan tempat untuk melepas kepenatan yang menimpa karena banyaknya tunututan dari pekerjaan, bertambah buruknya kualitas udara disuatu wilayah Kabupaten/Kota imbas dari maraknya industri dan kendaraan bermotor yang membuat udara semakin tercemar oleh polusi udara, dan juga kurangnya lahan untuk menampung air ketika hujan yang membuat banyak wilayah yang terendam banjir ketika hujan karena kurangnya wilayah resapan air.

The Effect Of Price Policy And Experiential Marketing On Repurchase Intention Mediated By Customer Satisfaction (Study at PT. Maybank Indonesia Finance Regional Jakarta)

The increase in the number of motorized vehicles can be seen from the data released by the Central Statistics Agency (BPS) explaining that in 2019 the number of vehicles spread in Indonesia reached more than 133 million units where this number increased by around 5.3% compared to the previous two years. The distribution of the total number of vehicles consists of motorcycles, private cars, freight cars and buses. Of the total number of vehicles circulating in Indonesia in 2020, DKI Jakarta contributed about 17% or 20 million vehicles to the total, where the number of vehicles also increased very significantly compared to the previous year. Another surprising fact is that the number of vehicles circulating in Jakarta exceeds the population of Jakarta based on population census data in 2020 which only reached 10.56 million people. However, in 2020 a decline in sales in new car transactions due to the Covid-19 pandemic was also unavoidable so that it became a challenge for PT Maybank Indonesia Finance, especially for customers who had already made transactions, of course, to maintain retention from these customers so that the intention to make transactions emerged. /buyback through PT Maybank Indonesia Finance, which this requires appropriate and effective strategies. This research is a quantitative study with 111 respondents spread across DKI Jakarta, using SMARTPLS 3.3 data processing. The results of the study show that all of the hypotheses studied in this study have a significant influence, so that PT Maybank Indonesia Finance must pay attention to many things to maintain customer retention for re-transactions.
