Penerapan Aplikasi Mobile Untuk Mencari dan Memberikan Pertolongan Terhadap Kerusakan Pada Kendaraan Berdasarkan Lokasi Terdekat
Get PDFFor motor vehicles and cars, each year always causes an increase in the number of motor vehicle problems such as leaky tires, running out of gas or breaking down and the number of problems always increases. Where when these problems occur drivers always have difficulty in finding the nearest workshop or help. To seek help for problems with vehicles in the city of Padang, through mobile devices becomes very important considering vehicle users who find it difficult to find help. In this study the author tries to resolve the above problems by creating an Android-based system that makes it easy for motorists and cars to find help with the problems they are experiencing later. In the study of this mobile application the author will utilize GPS on existing smartphones so that they can search for other people who are around the location to make it easier to find the nearest aid provider. The study was conducted from the stages of needs analysis, design, implementation, until testing

Implementasi Fuzzy Logic Controller Pada Kendali Kecepatan Sepeda Bertenaga Angin
Get PDFOne alternative for environmentally friendly vehicles is wind-powered bikes. This vehicle can reduce air pollution and can be convenient in big cities. The proposed bike is equipped with a distance sensor to sense the safe proximity to nearby obstacles. If the obstacles are below a reasonable distance, the mounted buzzer is active as the warning. This bike uses the wind generated by the 8045 hp dc rotation. The pulse-width (PWM) modulation is used to control a dc engine rotational speed with a fixed value of 155 = low and 255 = high. Fuzzy Logic Controller is used to increasing system effectivity to processes the input from the proximity sensor. The sufficient distance between the bike and the obstacles ahead, right and left, is set to be 1 meter. The PID controller ensures that the dc motor rotations are smooth and steady to ensure that the PWM value is still positive. In order to maintain a stable state Kp = 60, Ki = 4.2, and Kd = 2.9 are set as the appropriate settings for the used PID constants
Studi Komparatif Program Visual Dinamis untuk Pembelajaran Algoritma dan Pemograman Berorientasi Objek
Get PDFAs beginners, many first-year students have difficulty understanding object-oriented programming material. To help students learn algorithmic and object-oriented programming material researchers have developed visual programming (PV). Visual programming is a tool to facilitate learning programming. The concept of learning to use PV visualizes the work processes of algorithms and programming. This research aims to compare three dynamic PV tools for object-oriented learning programming that are the most studied. To determine the PV to be compared, a survey was conducted in an online journal database, such as IEEE explore, ACM, and several well-known online publishers. From the survey results, three dynamic PVs were chosen, most widely discussed, namely Jeliot 3, Ville and Jive. All three tools are installed and studied. Comparison results show that each dynamic PV has advantages on certain characteristics. The instructor can choose visual programming by considering the advantages of each PV
Pencarian Jalur berdasarkan Kepadatan Lalu Lintas Menggunakan Algoritma Koloni Semut
Get PDFDi kota besar seperti Surabaya yang mempunyai kepadatan lalu lintas yang cukup tinggi, merupakan permasalahan yang rumit untuk diselesaikan. Peningkatan jumlah pengguna jalan menyebabkan kepadatan yang semakin tinggi. Pada sistem lalu lintas yang bersifat dinamis, pencarian jalur berdasarkan jarak terpendek harus memperhitungkan kondisi kepadatan lalu lintas pada suatu waktu. Pengguna jalan lebih efektif dan efisien dalam menentukan jalur yang dilewati, apabila mempertimbangkan faktor kepadatan. Pada penelitian ini dilakukan pengembangan pencarian jalur menggunakan algoritma koloni semut (ant colony algorithm). Algoritma koloni semut diaplikasikan pada peta untuk menemukan jalur optimal berdasarkan jarak tempuh dengan mempertimbangkan kondisi kepadatan lalu lintas pada suatu waktu. Sistem yang dibangun dapat menjadi alat bantu bagi pengguna jalan untuk memilih jalan yang dilakukan berdasarkan informasi kondisi kepadatan, arah jalan dan serta jalur yang dapat dilalui oleh jenis kendaraan tertentu. Algoritma koloni semut dapat melakukan pencarian jalur dengan baik dengan sesuai dengan bobot jumlah lajur jalan dan jenis kendaraan.

Perancangan Aplikasi Pemesanan Travel Antar Kota Di Sumatera Barat Berbasis Android
Get PDFThe development in the field of technology is currently growing rapidly, one of the technological developments at this time is the internet. Then what is obtained by using the internet can also be utilized in the field of transportation, namely by making an Android mobile-based travel ticket booking information system using a smartphone. Travel is a type of transportation service that serves passengers with a door to door or pickup system at the booking address, then delivered to the destination address. However, the process of booking travel tickets today is still done traditionally by coming to the counter or branch office of travel so it takes a lot of time and is inefficient, and there are also several other ways to call a travel agent, sometimes such methods are not effective because of the occurrence of a pile of tickets without accurate data. Therefore this study aims to facilitate travel passengers in searching or booking Travel tickets in the West Sumatra Region by designing an Android mobile application. Apart from that in providing location information to the drivers of the traveling fleet to pick up passengers at certain locations by using Google Maps, and application features such as travel schedules, ticket checks, ticket reservations, and account registration
