"Buku yang berjudul "Soils manual for design of Asphalt Pavement Structures" ini dipersembahkan oleh The Asphalt Institute. "

"Konstruksi perkerasan jalan lentur (flexible Pavement), yaitu struktur yang terdiri atas campuran beraspal diatas lapis pondasi atas kemudian lapis fondasi bawah dan  tanah dasar. Perencanaan berada di ruas Jalan Simpang Sayut – Nanga Sarai Kecamatan Putusibau Kabupaten Kapuas Hulu Utara. Perencanaan ini meliputi Survey Lalu Lintas Harian Rata-rata dan menggunakan metode Manual Desain Perkerasan Jalan. Tujuan dari perencanaan ini adalah menentukan desain dan tebal lapis perkerasan lentur yang sesuai pada Ruas Jalan Simpang Sayut – Nanga Sarai Kecamatan Putusibau Kabupaten Kapuas Hulu Utara.

Flexible pavement construction, namely a structure consisting of asphalt mixture on top of the top foundation layer then the bottom layer and subgrade.. The planning is on  Simpang Sayut – Nanga Sarai road section, Putusibau District, North Kapuas Hulu Regency. This planning includes an Average Daily Traffic Survey and uses the Road Pavement Design Manual method. The aim of this planning is to determine the appropriate design and thickness of the flexible pavement layer for the Simpang Sayut - Nanga Sarai Road Section, Putusibau District, North Kapuas Hulu Regency."

"Oily-sludge is a waste product resulted form the activity of mining, transporting, storing, and refining of petroleum crude oil and categorized as hazardous waste. Therefore to deal with with this material become expensive and should be in line the environmental regulations. On the other hand, oily sludge can potentially be used as a rejuvenator to modify Buton Rock Asphalt bitumen for cold mix with better characteristics."

"This collection of ideas and results on topics of curve and surface design is intended for research in the academic environment as well as for practical use in industrial applications. Main emphasis is on minimal energy splines and geometric spline curves, and on techniques beyond tensor product surfaces."

"Kecelakaan berkendara menyebabkan sekitar 1.3 juta orang meninggal dan sekitar 20-50 juta orang mengalami cedera non-fatal setiap tahun nya, salah satu factor utama penyebabnya adalah human error. Komunikasi V2X merupakan salah satu teknologi yang dikembangkan dengan harapan dapat mengurangi kecelakaan akibat human error dan juga diharapkan akan dapat diaplikasikan dalam autonomous driving. Akan tetapi antena untuk komunikasi V2X masih perlu banyak perkembangan dan masih belum banyak dipakai di kendaraan yang sudah beredar di pasar, karena itu penelitian ini diharapkan dapat berkontribusi pada bidang ini. Untuk mendapatkan performa sistem yang baik diperlukan antena yang mempunyai kemampuan beamsteering. Pada penelitian ini dibuat antena susun microstrip yang bekerja pada frekuensi 5,9 GHz dan memiliki kemampuan beamsteering yang dapat meningkatkan keandalan dari antena V2X. Berdasarkan hasil yang sudah disimulasikan, antena sudah berhasil bekerja di 5,9 GHz dan memiliki gain yang cukup tinggi di kisaran 8-11 dBi tergantung konfigurasi yang sedang digunakan, simulasi menunjukan kapabilitas beamsteering telah terdapat pada rancangan dan sudah berhasil melakukan pembelokan beam sebanyak 10, 25, dan 40 derajat.

Road accidents result in approximately 1.3 million fatalities and around 20-50 million non-fatal injuries each year, with human error being a major contributing factor. V2X communication is a technology being developed with the hope of reducing accidents caused by human error and is also expected to be implemented in autonomous driving. However, the development of V2X communication antennas still requires significant advancements, and they are not yet widely used in vehicles currently available in the market. Therefore, this research aims to contribute to this field. To achieve a good system performance, antennas with beamsteering capability are needed. In this study, a microstrip array antenna operating at 5.9 GHz frequency was designed, which possesses beamsteering capability to enhance the reliability of V2X communication. Based on the simulated results, the antenna successfully operated at 5.9 GHz and exhibited a high gain ranging from 8-11 dBi, depending on the configuration used. The simulations demonstrated that the designed antenna has beamsteering capabilities, successfully steering the beam at angles of 10, 25, and 40 degrees."
