Abstract: The objectives of the presents study was  to explore mathematical models that could be used  to  estimate  the  number  of  accidents  on  interurban  toll  roads.  Preditive  models  were developed  by  relating  traffic  exposure  (average  daily  traffic  and  road  section  length)  with  the number  of  accidents  per  unit  of  time.Accident,  roadway  section  and  traffic  volume  data  were obtained  from  Jagorawi,  JakartaCikampek,  padaleunyi,  and  palikanci  toll  road.  Accident  rate models were developed from those data using  generalized linear modelling (GLM) techniques. The conclusions  from  the  study were:  (1)  linier  regression model was  not  appropriate  to  be  used  to predict  accidents  number,  because  accident  occurence  did  not  follow  normal  distribution,  (2) Poisson regression possessed accident occurence characteristics: descrete, rare and random, and (3)  Negative  Binomial  distribution  was  more  appropriate  to  represent  accident  occurence phenomenon with overdispersion. Keywords: accident rate, generalized linear modelling, Poisson regression, nagative binomial regression.  Abstrak: Penelitian  ini  bertujuan  untuk mengeksplorasi model matematis  yang  dapat  digunakan untuk  meramalkan  jumlah  kecelakaan,  pada  suatu  ruas  jalan  tol  antar  kota.  Model  prediksi dikembangkan  dengan  menghubungkan  paparan  lalulintas,  yang  dinyatakan  dengan  volume lalulintas dan panjang ruas jalan, dengan keselamatan, yang dinyatakan dalam jumlah kecelakaan per satuan waktu.

Abstract

This study aims to uncover the efforts of accountants to reduce fraud. The study uses an interpretive approach with a phenomenological method to see phenomena that are directly related to the symptoms that arise around humans that are organized in the sphere of interaction between the accountant profession, clients, and third parties. The data in this study were obtained from observations in the field by actively participating in each activity, in-depth interviews related to efforts to avoid fraudulent practices with people who are directly involved in the world of accountants. Data analysis was performed using noema and noesis analysis. The results showed that there were three efforts that accountants could make when they were employed, such as religiosity, professionalism, and materialism. After formulating the results based on an analysis of conversations with the informant, it can be concluded that what must be done by the accountant is to combine the three efforts and apply them to the work culture. Keywords: Fraud, Accountants, Phenomenology, Religiosity, Professionalism

Abstract

The research is aimed to figure out the comparison of the strength capacity and economic value comparison of castellated steel beam to its equivalent IWF beam. The profile of the castellated steel beam in this study included all profiles of castellated steel beam on the market based on the products catalog of the castellated steel beam from PT. Gunung Garuda. The finite element method was used in this study with the aid from Abaqus program to get a comparison of the strength capacity of castellated steel beam to its equivalent IWF beam. The next stage next involved the calculation of a comparison of the economic value of the castellated steel beam with hexagonal holes with to its equivalent IWF beam. The results of the study showed that the castellated steel beam experienced an increase in the strength capacity of 1,189 up to 2,330 times compared to its equivalent IWF beam. The comparison of the strength capacity between the castellated steel beam and its equivalent IWF beam is at 1,010 up to 1,539. Based on the combination between the comparison of strength capacity and the economic value, there are 14 (58.33%) profiles of the castellated steel beam which is categorized as efficient in terms of the design of the structure and cost, there are four (16.67%) profiles of the castellated steel beam which is categorized as efficient in terms of the design of the structure but not efficient in terms of cost, and there are 6 (25.00%) profiles of the castellated steel beam which is categorized as inefficient in terms of the design of the structure and cost. The results of this study indicate that the castellated steel beam can replace its equivalent IWF beam. Selection of profile of the castellated steel beam is appropriate to provide efficiency in terms of weight of the structure between 58.5% to 15.1% and can provide efficiency in terms of cost of between 48.4% to 0.9%.

Abstract

The development of a city usually is accompanied by traffic congestion and air pollution problems. The appropriate strategy to solve these problems has been debated for long time. The proponents of new urbanism believe that the problem can be improved by forcing more people and more cars into smaller areas . They assume that by forcing densities higher, public transit can be provided better and more efficient, so that people will be more inclined to abandon their automobiles and use public transit, bicycles or walking as an alternative. On the contrary, anti-urban traditions believe that densifying urban areas will only worsen traffic congestion, and in turn will worsen air pollution. So that the best approach to solving the problem would to let urban sprawl, to dispersetraffic and to make it move faster. This paper describes both approaches and the impacts, and discuses which one is the best from Indonesian perspective.Keywords: urban density, urban sprawl, new urbanism, smart growthPerkembangan kota biasanya dibarengi dengan masalah kemacetan lalu-lintas dan polusi udara. Strategi apa yang harus ditempuh untuk mengatasi hal tersebut merupakan perdebatan yang panjang. Para pendukung new urbanism percaya bahwa kemacetan dan polusi bisa ditanggulangi dengan memaksakan lebih banyak orang dan kendaraan dalam kawasan yang sempit. Dengan lebih terkonsentrasi, penyediaan angkutan umum bisa lebih baik dan efisien, sehingga orang akan mengurangi penggunaan kendaraan pribadi  dan cenderung menggunakan angkuatan umum, bersepeda atau berjalan kaki. Sebaliknya budaya suburban dengan gagasan urban sprawl menganggap bahwa kemacetan disebabkan karena terlalu banyaknya kendaraan di wilayah yang sempit, dan pada gilirannya kemacetan memperparah polusi. Oleh karena itu kota harus dibiarkan berkembang menyebar, untuk menyebar lalu-lintas. Tulisan ini membahas kedua pandangan tentang kepadatan kota, dampaknya, serta mengkajinya dalam perperktif geografis dandemografis, yang manakah yang terbaik untuk Indonesia.Kata Kunci: kepadatan kota, pemekaran kota, new urbanism, pertumbuhan cerdas

Abstract

Accident prediction models is related to the quantification of the relationship betweenaccidents that occured at certain location with factors that influence it at a particular time. Themodels could provide ideas how each variable contributes to the accident that occured at aparticular location. The purpose of the strudy was to develop toll road accident prediction models byconsidering hourly traffic flow. Microscopic analysis result shows that the relationship betweenaccident frequency and hourly traffic can be represented by exponensial step-functions. Up to 700vehicle/hour accident frequency increases exponentially, then it decreases exponentially as trafficflow increases furthermore. This trend was common for total, single-vehicle, and multi-vehicleaccidents. Model prediksi kecelakaan merupakan kuantifikasi hubungan antara kecelakaan yangterjadi pada suatu lokasi dengan faktor-faktor yang berpengaruh pada waktu itu. Model prediksidapat memberi gagasan bagaimana masing-masing variabel tersebut berkontribusi menyebabkankecelakaan yang terjadi di lokasi tersebut. Penelitian ini bertujuan untuk mengembangkan modelprediksi kecelakaan yang terjadi pada ruas jalan tol dengan berdasarkan volume lalu lintas per jam(hourly traffic flow). Analisis secara mikroskopik dengan menggunakan volume lalulintas per jamsebagai variabel bebas menunjukkan bahwa hubungan antara besarnya frekuensi kecelakaandengan volume lalulintas per jam berbentuk eksponensial bertingkat. Sampai dengan nilai volumelalulintas 700 kendaraan/jam hubungan frekuensi kecelakaan dengan volume lalulintas per jamdapat dinyatakan dengan fungsi eksponensial positif, sedangkan di atas nilai volume lalulintas 700kendaraan/jam hubungannya dapat dinyatakan dalam bentuk fungsi eksponensial negatif. Hal iniberlaku baik untuk kecelakaan total, tunggal, maupun jamak
