Perkembangan sistem transportasi memegang peranan penting dalam menunjang mobilisasi. Perkembangan tersebut sejalan dengan perkembangan zaman dan kebutuhan masyarakat akan transportasi. Salah satu pengembangan yang mulai banyak diperhatikan orang adalah trem tanpa rel, yang terjadi karena adanya perkembangan teknologi kecerdasan buatan, sensor, dan metode kontrol pengikut jalur. Pada makalah ini dibahas pengembangan sistem kontrol dan sistem pendeteksi objek yang diterapkan pada trem otonom tanpa rel, dengan tujuan agar trem mampu berjalan mengikuti jalur virtual yang sudah ditetapkan serta mendeteksi objek penghalang beserta rambu lalu lintas. Ketika trem berhasil mendeteksi objek penghalang, trem akan melakukan pengukuran jarak dengan menggunakan konsep penglihatan stereo. Untuk itu maka metode kontrol pengikut jalur yang diterapkan pada penelitian ini adalah kontrol logika fuzzy. Selain itu, metode Line of Sight (LoS) diterapkan agar selisih jarak antara lokomotif terhadap segmen garis yang diikuti dapat diminimumkan sehingga trem dapat berjalan mengikuti garis virtual yang sudah ditentukan. Implementasi metoda-metoda tersebut pada model kereta dan juga teknik mendeteksi beberapa penghalang perjalanan kereta menunjukkan hasil yang memuaskan.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.

Abstrak— Penelitian ini bertujuan untuk mengetahui pola trafik internet pada beberapa lokasi yang diteliti. Pengamatan dilakukan selama dua belas (12) bulan. Data diolah dengan metode statistika untuk mendapatkan proyeksi pengguna internet dan kebutuhan titik hotspot. Penelitian menghasilkan rekomendasi kebutuhan hotspot dengan mempertimbangkan mobilitas pengguna internet dan countur lokasi. Rekomendasi perangkat berbeda pada tiap lokasi dari sisi geografis dan padatnya area. Line of Sight mempengaruhi kemampuan perangkat dalam memancarkan signal internet.Hasil penelitian menunjukkan terjadinya peningkatan pengguna internet pada hari raya umat Islam, Hal ini diduga karena mayoritas masyarakat pada lokasi tersebut muslim. Proyeksi pelanggan di 300 desa didapatkan minimum penetrasi 36,7% dan maksimal 85.2%. Rekomendasi sejumlah 940 Titik hotspot dengan area bandwith secara statik sebesar 3Mbps (aggregate download dan upload).  Penelitian memperhitungkan Link Budget perangkat backhoul tier 3 dengan frekuensi 24Ghz. Setiap  perangkat dapat menangani rata-rata jumlah device yang terkoneksi secara bersama sejumlah > 200 Device teknologi Wi-Fi (IEEE 802.11). Beban total trafik  > 1,6 GBPS. Rekomendasi Arsitektur  broadband wireless access Berbasis Hotspot Di Jawa Timur yaitu Surabaya 140 lokasi dengan 400 titik hotspot, Mojokerto sejumlah 70 lokasi dengan 210 titik hotspot. Pandaan sejumlah 80 lokasi dengan 240 titik hotspot Malang  43 lokasi dengan 90 titik hotspot.Kata kunci: Broadband Wireless Access, Hotspot, Line Of SightAbstract— This study aims to determine the pattern of internet traffic in several locations in Jawa Indonesia. Observations were made for twelve (12) months. Data is processed using statistical methods to obtain projections of internet users and hotspot needs. This study produces recommendations for hotspot needs by considering internet user mobility and location contours. Device recommendations vary by location in terms of geography and crowded areas. Line of Sight affects the ability of the device to emit internet signals. The results showed an increase in internet users on Muslim holidays. Projected customers in 300 villages have a minimum penetration of 36.7% and a maximum of 85.2%. The recommended number of 940 hotspots with a static area of 3Mbps (download aggregate and upload). This study takes into account the tier 3 Link Budget backhoul device with a frequency of 24Ghz. Each device can handle the average number of devices that are connected together by> 200 Wi-Fi technology devices (IEEE 802.11). Total traffic load> 1.6 GBPS. Architectural recommendations for broadband wireless access based on hotspots in East Java, Surabaya, 140 locations with 400 hotspots, Mojokerto with 70 locations with 210 hotspots.
