Negative Impacts

The transportation problem is one of the main issues that are difficult to solve in several big cities. When congestion occurs, it can disrupt community activities. We already know that "congestion will cause various negative impacts, both on the driver and in terms of the economy and environment. The intersection of four highways, Blitar City, East Java, has the intensity of a dependable vehicle. This is because around the area, and there are markets, residential areas, public force terminals, and squares. Besides that, the place is accessible to public transportation from Blitar City to Malang City. In this study, the authors conducted a field survey of traffic flow, road geometry, and side barriers during rush hour during sunny weather for seven days at the intersection. From the results of the analysis, minor paths have disrupted major pathways and caused delays of 35%. This figure has exceeded the requirements recommended by MKJI 1997. From the results of this study, it can also be an evaluation material so that in the future, the intersection of four Highway, Blitar City, East Java, can be functioned better.Masalah transportasi adalah salah satu masalah utama yang tidak mudah dipecahkan di beberapa kota besar. Pada saat kemacetan terjadi bisa menggangu aktifitas masyarakat. Telah kita ketahui, bahwa kemacetan akan menimbulkan berbagai dampak negatif, baik terhadap pengemudi maupun ditinjau dari segi ekonomi dan lingkungan. Simpang empat Jl. Raya Barat, Kota Blitar, Jawa Timur merupakan salah satu persimpangan dengan intensitas kendaraan yang cukup padat. Hal ini disebabkan karena disekitar simpang empat tersebut terdapat pasar, pemukiman penduduk, terminal angkot, alun – alun. Selain itu, simpang empat tersebut merupakan akses untuk angkutan umum dari Kota Blitar menuju Kota Malang. Pada penelitian ini penulis melakukan survey lapangan terhadap arus lalulintas, geometri jalan, dan hambatan samping pada jam sibuk saat cuaca cerah selama 7 hari pada simpang empat tersebut. Dari hasil analisa, jalur minor sudah mengganggu jalur mayor dan menyebabkan tundaan sebesar 35%. Angka ini sudah melampaui syarat yang dianjurkan oleh MKJI 1997. Dari hasil penelitian ini juga dapat menjadi bahan evaluasi agar kedepannya simpang empat Jl. Raya Barat, Kota Blitar, Jawa Timur, bisa difungsikan dengan lebih baik.

Negative Impacts

Hospital is one of the most important and beneficial public services in the world, therefore, these facilities should be located in a rational manner. Increasing the population of countries particularly developing countries and remote areas leads to the demand for new public health facilities and hospitals. No matter who provides the healthcare facilities, the most important issue is where to locate a new hospital to provide, both facility location and attractiveness. Hospital proper site selection has a vital role in hospital construction and management. From the aspect of the government and healthcare organization, appropriate hospital site selection will help optimize the allocation of medical resources, matching the provision of health care with the social and economic demands. From the aspect of the investors and operators of the hospital, optimum hospital site selection will definitely be cost-saving on capital strategy. On the other hand, establishing a hospital in urban districts has its own positive and negative consequences. The positive impacts of establishing a hospital in an area are that it increases property value in the neighboring periphery as well as improving healthrelated accessibility for the residents of that urban district. The negative impacts of establishing a hospital in an area are negative side-effects such as environmental contamination and inducing new waves of traffic flow. Then, the adjacent community is impacted by forms of increased traffic flow, increased emergency vehicle usage in residential areas. Therefore, in hospital site selection should be tried to reduce the negative impacts. Then, main aim of this paper is to select a site for the building of a new hospital in Iskandar Malaysia using GIS-based Multi-Criteria Analysis (MCA) with consideration of various factor criteria, and constraint criteria in order to balance the medical resource there.

The increasing numbers of people and buildings that continue to grow and tend to be uncontrolled in the settlement causing some negative impacts one of them is the consistency of land allotment. This has resulted in some impacts such as ineffective utilities and environmental infrastructures, no mitigation system, and the unavailability of space for public spaces and other supporting facilities that supposed to be available within a settlement. Kampung Arab is one of a densely populated settlements located in the middle of business center area of Manado City, occupies the Mahakam riverbank. The limited space available in Kampung Arab has caused the settlements tend to be slummed and doesn’t have public open space as one of the residential support facilities. In addition, this settlement expands riverbanks so the functions of riverbanks become disturbed, and these settlements are often at risk of flooding. The purpose of this research is to analyze the function of Mahakam riverbanks against flood risk and to analyze the possibility of public space and pedestrian ways availability at the location of Mahakam riverbanks around the Kampung Arab settlement. The research method is qualitative descriptive method. Primary data were obtained through field observation, documentation, and interviews. The research is located in Kampung Arab settlement which occupies the banks of Mahakam River. Further analysis is done: 1) analysis of existing settlement of Kampung Arab to the Mahakam River related to: building’s orientation, river border, activity and behavior of society 2] analysis of public open space availability and its former elements, 3] analysis of settlement utility system and at the final stage conducted an analysis related to community activities and behavior. Expected results through this research are: improving function and quality of Mahakam River, restoring the function of riverbanks and public open space availability as social interaction space.

Alien invasive species can have negative impacts on the functioning of ecosystems. Plantation species such as pines have become serious invaders in many parts of the world, but eucalypts have not been nearly as successful invaders. This is surprising considering that in their native habitat they dominate almost all vegetation types. Available theory on the qualities that characterise invasive species was used to assess the invasive potential of Eucalyptus grandis – a common plantation species globally. To determine rates of establishment of E. grandis outside plantations, we compared population demographics and reproductive traits at two locations in Mpumalanga, South Africa: one at higher elevation with more frost. Eucalyptus grandis has a short generation time. We found no evidence that establishment of E. grandis was limiting its spread into native grassland vegetation, but it does appear that recruitment is limited by frost and fire over much of its range in Mpumalanga. Populations at both study locations displayed characteristics of good recruitment. Size class distributions showed definite bottlenecks to recruitment which were more severe when exposed to frost at higher elevations. Generally, the rate of spread is low suggesting that the populations are on the establishing populations’ invasion stage. This research gives no indication that there are any factors that would prevent eucalyptus from becoming invasive in the future, and the projected increase in winter temperatures should be a cause for concern as frost is currently probably slowing recruitment of E. grandis across much of its planted range.Conservation implications: Eucalyptus plantations occur within indigenous grasslands that are of high conservation value. Frost and fire can slow recruitment where they occur, but there are no obvious factors that would prevent E. grandis from becoming invasive in the future, and monitoring of its rates of spread is recommended.

Transfer Of Function

It is known that South Tangerang City is one of the fastest growing cities. This indicates that the increasing number of users of transportation means that facilities for transportation users need to be considered, one example is pedestrians. The unrealized development of pedestrian facilities is caused by the transfer of function of pedestrian facilities for public needs and insufficient space for pedestrians. The lack of pedestrian facilities causes pedestrians to pass by and has an impact on public transportation that is currently operating, causing congestion. Sudimara Station is located in Ciputat District, South Tanggerang City, with a population growth rate of 3.0% in 2019. All buildings are provided for pedestrians to provide services to pedestrians so as to improve pedestrian smoothness, safety and comfort. The purpose of this study was to analyze the performance of pedestrian facilities at Sudimara Station. The method used is direct field survey and data processing using Microsoft Excel, AutoCad. The results of the author's research include the minimum width of the sidewalk in 2020 and 2025 of 1.5 - 1.6 meters and the service level of pedestrian facilities is classified as A, which means that pedestrians can walk freely, including being able to determine the direction of walking freely, at speed. relatively fast without causing interference between pedestrians. the existing conditions of the sidewalks in 2020, namely there are several obstacles for pedestrians such as the presence of street vendors, public transportation parking carelessly, and several motorbikes parked carelessly, buying and selling activities in markets close to Sudimara station and the absence of integration facilities around the place. the. Planning that the authors do is to increase the width of the sidewalk to 1.5 meters, and the addition of street lighting facilities.

Due to the policy of the Doi moi in Vietnam started in 1986, Hanoi has undergone many important changes. Currently, Hanoi's traffic is characterized by seemingly continuous motorcycle flows - a representative of high personal mobility in the context of rising incomes. Congestion, dust, pollution, insecurity, overload, etc., they are important keywords to describe Hanoi's urban traffic. Hanoi has put in place a number of policies to improve the transportation system. In 2017, in Hanoi's new mobility improvement project, there is a regulation on motorcycles: “The municipality will zone by limiting the activities of motorcycles according to the infrastructure and the service capacity of the public transportation system to stop motorcycle activities in the central districts in 2030” that becomes controversial. This article, based on the results of surveys assessing the level of satisfaction and desires of people about traffic at the KDTMs of Hanoi, analyzes the differences between the wishes of the municipality and the practices of Hanoi, through habits, modes of mobility of KDTM residents - the new residential areas of Hanoi that bring a different atmosphere of habitat compared to existing neighborhoods, by changing the mode of (re)making of the city. How will the traffic of KDTM residents be affected by this decision as well as how KDTMs will participate in the sustainable transportation of Hanoi?. It is the KDTMs with their “novelties” that will have to become pioneers creating opportunities of the changing of Hanoi traffic.

Riset dampak pemberitaan penyalahgunaan formalin di sektor kelautan dan perikanan telah dilakukan pada tahun 2006. Riset ini bertujuan untuk melihat sejauhmana dampak yang ditimbulkan akibat pemberitaan tentang penyalahgunaan formalin di sektor kelautan dan perikanan pada produsen dan konsumen. Pendekatan studi digunakan melalui analisis kebijakan. Data primer dan sekunder dirumuskan sesuai keperluan analisis kebijakan ini yaitu penelusuran terhadap dampak pemberitaan formalin terhadap produsen dan konsumen di sektor kelautan dan perikanan. Kemudian data hasil verifikasi dan survey lapang yang berasal dari kuesioner dan catatan lapangan (field notes) diolah secara deskriptif untuk mendapatkan interpretasi logis. Lokasi studi ditetapkan secara sengaja (purposive) dengan kriteria tersebut merupakan sentra penanganan dan pengolahan produk perikanan dan diberitakan banyak menggunakan bahan kimia formalin yaitu Jawa Barat (Karawang), Jawa Tengah (Semarang), DKI Jakarta dan Bandar Lampung. Hasil studi menunjukkan bahwa bagi produsen yang meliputi nelayan, pengolah dan pembudidaya ikan dampak negatif dari pemberitaan formalin adalah menurunnya permintaan ikan hasil tangkapan dan olahan sehingga pendapatan nelayan dan pengolah menjadi berkurang, sedangkan bagi konsumen dampak negatifnya konsumen jadi takut mengkonsumsi ikan laut dan hasil olahan sehingga lebih memilih mengkonsumsi tempe/tahu dan telur. Dampak positifnya bagi produsen baik nelayan dan pengolah yaitu sebagian dari mereka jadi mengetahui bahwa formalin tersebut membahayakan dan berusaha tidak menggunakan lagi. Dampak positif bagi konsumen bertambah pengetahuan tentang bahaya formalin sehingga mereka akan lebih hati-hati dalam mengkonsumsi ikan dan untuk sementara konsumsi ikan mereka dialihkan ke ikan hasil budidaya yang banyak dijual dalam kondisi hidup. Tittle: The Impact of Announcement on The Mis-used of Formalin in Marine and Fisheries SectorResearch on impact of mis-used of formalin in marine and fisheries sector have been done in 2006. The aim of the research was to show the impact of announcement on the mis-used of formalin to producers and consumers. Policy analysis approach was used as the method of study. Primary and secondary data were formulated accordingly to meet the requirement of the policy analysis, that is impact of media release on both side of producers and consumers. Verified data and field survey processed descriptively to build logical interpretation.The locations of study were specified in purpose to represent the center of handling and processing of fisheries product indicated with formalyn abuse. These location were West Java (Karawang), Central Java (Semarang), DKI Jakarta and Bandar Lampung. The results of study showed that the negative impacts of the news on formalin abuse to the producers were decreasing on demand of catch and processed fish products, which in turn reduce the income of the fisherman and fish processors. On the other side, the consumer shift their preference to other products such as tempe, tofu and eggs. The positive impacts to the fisherman and fish processors were the knowledge of the danger of formalin abuse on their products and they avoid to use the chemical. The positive impact on fish consumers were the awareness on formalin use on health arose and temporary their fish consumption shifted to the aqucultured fish which sold in living form.

This paper is concerned with the analysis of some worrying present tendencies of urban sprawl in the large, important economic centers of Romania. It focuses on the tendency of building new residential apartments on the outskirts of the big cities. Most of these developments target young people that belong to a still-developing middle class. Big problems emerge, however, when real estate investors take advantage of the buyers’ lack of experience and of the authorities’ poor management, offering small, badly-built apartments in new residential areas which are designed around only one function: housing. The absence of complementary functions that could support the development of communities gravely impairs the inhabitants’ quality of life. At the local level, I was able to identify two main problems: the absence of the necessary infrastructure to support such a massive increase in population, and the absence of local amenities. On a larger scale, the consequences are significant as well: chronic traffic jams due to the large number of people who commute to Bucharest daily, for work. Even though at first Popeşti-Leordeni (a satellite-town of Romania’s capital) was considered a good housing option, the people living there are rapidly becoming highly unsatisfied with their quality of life. In their opinion, the biggest problems of this urban area are the absence of green spaces, of leisure services, of parking options, and of means of public transportation. To these complaints, the inhabitants add dissatisfaction with the general problems caused by the endless building sites, which also represent one of the main causes for the lack of cleanliness, bad roads, noise and pollution plaguing the area. This paper, based both on the analysis of statistical data and on empirical research, aims to show that Popeşti-Leordeni, especially the New Popeşti neighborhood, is an example of bad housing caused by corruption, investors’ greed, bad management on the part of the authorities, and the young buyers’ inexperience. Keywords: quality of life; urban sprawl; satellite-town; mono-functionality; community.
