"Tujuan Pembangunan Berkelanjutan mengamanatkan penurunan jumlah kematian dan cedera akibat kecelakaan lalu lintas sampai 50% di tahun 2020. Kecelakaan lalu lintas menjadi penyebab utama kematian penduduk kelompok usia produktif dan 90% terjadi di negara berpenghasilan rendah dan menengah. Di Indonesia prevalensi cedera akibat kecelakaan transportasi darat mengalami peningkatan dari sebesar 25,9% pada 2007 menjadi 47,7% pada 2013. Studi kecelakaan lalu lintas menganalisis pengaruh dari faktor-faktor penyebab, yaitu perilaku pengguna jalan, kendaraan, dan jalan.Di negara berkembang faktor jalan perlu mendapat perhatian lebih karena standar kualitasnya tidak sebaik negara maju. Di Indonesia kajian kecelakaan lalu lintas dilakukan dalam bentuk studi kasus.Penelitian ini bertujuan untuk menganalisis pengaruh faktor kondisi permukaan jalan dan faktor penerangan jalan terhadap jumlah korban kecelakaan lalu lintas di seluruh Indonesia menggunakan metode regresi negative binomial.Wawancara dengan para pemangku kebijakan dilakukan untuk memperkuat hasil penelitian. Analisis dilakukan menggunakan 765.678 data cross section yang dicatat oleh Korps Lalu Lintas Kepolisian Republik Indonesia (Korlantas).Hasil estimasi menunjukkan bahwa kondisi permukaan jalan yang buruk meningkatkan jumlah korban kecelakaan fatal, sedangkan penerangan yang buruk meningkatkan jumlah korban kecelakaan lalu lintas pada berbagai tingkat keparahan. Dibandingkan peningkatan kondisi permukaan jalan, peningkatan lampu penerangan jalan memberikan manfaat tiga kali lebih besar dan membutuhkan biaya 50% lebih rendah.

SDGs has mandated each country to halve road accident-caused death by 2020. Road accidents are the main cause of death for the productive age population and 90% occur in developing countries. In Indonesia the prevalence of injuries due to land transportation accidents has increased from 25.9% in 2007 to 47.7% in 2013. Road accidents analysis identify the influence of the causal factors, such as behavior of road users, vehicles, and road factors. We should pay more attention on road factors in developing countries because the road standard quality is not as good as in developed countries. In Indonesia the study of road accidents is mostly carried out in form of case studies.This study aims to analyze the influence of road surface conditions and road lighting factors on the number of casualties using the negative binomial regression method. Interviews with policy makers are held to enrich this study. The analysis was carried out using 765,678 cross section data which is recorded by the Indonesian National Police Traffic Corps.Results showed that poor road surface conditions increase the number of fatal casualties, while poor road lighting increases the number of casualties at all injury level. Compared to road surface improvement, road lighting provides benefits three times greater and requires 50% lower costs."

"Salah satu yang menjadi faktor perubahan iklim dan pemanasan global adalah meningkatnya konsentrasi gas rumah kaca (GHG) pada lapisan atmosfer. Peningkatan gas rumah kaca (GHG) disebabkan karena aktivitas manusia, sektor energi menjadi faktor kedua terbesar penyumbang emisi gas rumah kaca karena masih menggunakan energi tidak terbarukan. Indonesia memiliki target untuk mencapai net zero emission di tahun 2050, sehingga diperlukan metode yang tepat untuk mencapat target tersebut. Direct Air Capture (DAC) merupakan teknologi carbon capture yang dapat menghilangkan emisi karbon secara permanen di atmosfer. Penelitian ini bertujuan untuk menemukan desain geometri yang optimal pada sistem DAC, variasi desain geometri fin meliputi tinggi fin, tebal fin dan jarak antar fin untuk mencari nilai adsorption uptake terbesar pada sistem DAC yang dapat dicapai dalam waktu yang sesingkat mungkin dan dalam kondisi temperatur rendah. Hasil dari simulasi menunjukkan distribusi temperatur dan adsorption uptake. Pada penelitian ini terdapat 10 variasi dari A sampai J. Berdasarkan hasil analisa, nilai adsorption uptake tertinggi terdapat pada variasi E (0,13 x 7) mm sebesar 1,0059 kg/kg dalam waktu 792 detik dan nilai adsorption uptake terendah adalah 0,6078 kg/kg dalam waktu 395 detik pada variasi D (1,13 x 11) mm. Optimasi dilakukan menggunakan RSM menghasilkan titik optimum dengan tebal fin 0,33 mm, tinggi fin 11 mm akan menghasilkan respon berupa temperatur sebesar 316,565 K, nilai adsorption uptake sebesar 0,91401 kg/kg dalam waktu 547,092 detik. Nilai desirability 0,676, berarti titik optimum mampu mencapai respon kriteria yang diharapkan sebesar 67,6%.

One of the primary contributors to climate change and global warming because the concentration of greenhouse gases (GHGs) was increased in atmosphere. The rise is largely attributed to human activities, with the energy sector being the second largest contributor due to its continued reliance on non-renewable energy sources. To mitigate this, Indonesia has set a goal to achieve net-zero emission by 2050, necessitating an appropriate to reach this target. Direct air Capture (DAC) is one of the technologies for carbon capturing that can permanently eliminating carbon emission from the atmosphere. The objective of this study is to identify an optimal geometric of fin design for the DAC. The design variations include fin heigh, fin thickness and the distance between the fins. These variations aim to identify the design that yields the highest adsorption uptake value in the DAC system in shortest possible time and under low-temperature conditions. The simulation results demonstrate the distribution of temperature and adsorption uptake. This study examines 10 variations, labeled from A to J. According to the analytical results, variation E (0,33 x 7) mm achieves the highest adsorption uptake value of 1,0059 kg/kg within 792 seconds, while the lowest value is 0,6078 kg/kg , achieved within 326 seconds in variation D (1,13 x 11) mm. Optimization carried out using the response surface method reveals on optimal point with a fin thickness of 0,33 mm and a fin height 11 mm. This configuration generates a temperature of 316,565 K and adsorption uptake value of 0,91401 kg/kg within 547,092 seconds. A desirability value of 0.676 means that the optimum point is able to achieve the desired response criteria by 67.6%."

"Bahan aditif BNA-R dan Zeolit dapat mempengaruhi kekesatan permukaan pada campuran aspal hangat, terutama pada bagian permukaan aspal sebelum terlintasi dan sesudah terlintasi sebanyak 7560 lintasan dengan menggunakan Wheel Tracking Machine. Pengujian skid pada penelitian ini menggunakan alat British Pendulum Tester yang telah dimodifikasi agar dapat dilakukan pengujian dengan temperatur yang diinginkan. Hasil penelitian menunjukkan bahwa BNA-R dapat meningkatkan nilai skid pada awalnya, namun BNA-R tidak dapat mempertahankan kenaikan nilai skid tersebut setelah campuran aspal dilintasi sebanyak 7560 lintasan. Untuk bahan tambah zeolit terbukti bahwa aditif tersebut dapat meningkatkan nilai skid dan menaikkan ketahanan aspal terhadap temperatur.

BNA R and zeolite additives can affects the skid resistance of warm mix asphalt, especially on the surface of the asphalt before it passes through and after 7560 as many passes through the track by using the Wheel Tracking Machine. This study used a British Pendulum Tester, which has been modified in order to be tested with the desired temperature.

The results showed that the BNA R can increase the value of skid at first but BNA R can not sustain the increase in the value of the skid after the asphalt is crossed by as much as 7560 tracks. For added zeolite material is proven that such additives can increase the value and increase skid resistance versus asphalt temperature."

"This book comprises the proceedings of the conference Faszination Hybrider Leichtbau 2018, which took place in Wolfsburg.The conference focused on new methods and technologies for the development and production of multifunctional and hybrid lightweight solutions in large-scale vehicle manufacturing. Further, it promoted the exchange of insights and lessons learned between experts from industry and academia.Lightweight design and construction are key technologies for the development of sustainable and resource-efficient mobility concepts. Material hybrid structures, which combine the advantages of different materials (e.g. fiber-reinforced plastics and metals), have a high potential for reducing weight, while simultaneously expanding component functionality. However, the efficient use of functional integrated hybrid structures in vehicle construction, requires innovations and constant developments in vehicle and production technology. There is a great demand for affordable lightweight construction in mass production that takes into account the increasing requirements in terms of variant diversity, safety and quality- particularly with regards to new methods and technologies."

"This state-of-the-art study of the techniques used for designing curves and surfaces for computer-aided design applications focuses on the principle that fair shapes are always free of unessential features and are simple in design. The authors define fairness mathematically, demonstrate how newly developed curve and surface schemes guarantee fairness, and assist the user in identifying and removing shape aberrations in a surface model without destroying the principal shape characteristics of the model. Aesthetic aspects of geometric modeling are of vital importance in industrial design and modeling, particularly in the automobile and aerospace industries. Any engineer working in computer-aided design, computer-aided manufacturing, or computer-aided engineering will want to add this volume to his or her library. Researchers who have a familiarity with basic techniques in computer-aided graphic design and some knowledge of differential geometry will find this book a helpful reference. It is essential reading for statisticians working on approximation or smoothing of data with mathematical curves or surfaces."
