Judul: Perancangan dan implementasi logika Fuzzy pada Mikrokontroler ATMega16 untuk robot penghindar halangan
Abstrak: Robot was created to relieve human tasks. One of them is an obstacle avoidance robot. This robot has an ability to avoid obstacles and to move around autonomously in accordance with the rules embedded in it. In this study, fuzzy logic is implemented on the microcontroller ATMega16 in obstacle avoidance robot system design for easing in defining the object's position and accelerating the speed based on distance objects. This robot system is capable of handling three inputs and two outputs. Input is accepted as the value of the distance through the three ultrasonic sensors and the outputs are the speed and the angle of the robot turns. The output of fuzzy system is displayed on the LCD character 16x2. In the decision taking, Mamdani fuzzy modeling was used because it is intuitive. This system consists of ATMega16 microcontroller as hardware and CodeVision AVR as the compiler and downloader of the program into ATMega16 microcontroller and Matlab as the fuzzy simulation program. In the test, the results of fuzzy in Matlab are compared to the human expert opinion. The result of the fuzzy in Matlab can be accepted by the human expert. In the experiment, the results of fuzzy in Matlab are compared to the embedded systems. For the speed test, it produces 0.44% of average error with 99.56% accuracy rate. For the steering angle, it produces 0.22% of average error with 99.56% accuracy rate. The average fuzzy execution time of each rule in the microcontroller is 0.184441 ms. The fastest execution time is in rule 1, that is when three input sensors are in the close range. The longest time is in rule 27, that is when three input sensors are the far range.

Judul: Pengendalian gerak mobil dengan penerapan fuzzy inference system
Abstrak: The driver assistance system is a complex mobile robot system which was designed and built by european car producers to help drivers to control a car. The system makes a car able to sense its surroundings with the aid of various electronic sensors while mechanical actuators were used to move it around. It can make cars to stop automatically within the distance to the obstacles around and reduced car accidents. This paper presents a miniature of a driver assistance system which was designed and built on 1:10 scale R/C car. The fuzzy car adapts fuzzy inference system as its control system. Fuzzy inference system helps to simplify a complex driver assistance system by generating the control system from human experience and it allows to build a complex system easily. The fuzzy inference system is embedded on a micro-controller. The micro-controller control the fuzzy car by giving the instructions to the mechanical actuators. Fuzzy car could sense the distance and the track line with the aid of various electronic sensors. The design consisted of two main sections : software analysis for the fuzzy system with the programs which were integrated to the electronic components and electronic analysis which aid fuzzy system to take control of the mechanical actuators. In this paper it is shown that the fuzzy car moves through the track by line detection using proximity sensors and accelerated by object distance detection using sonar sensors. Fuzzy car can move and accelerate automatically by guiding those sensors detection. The result of this research shows a complex control system can be built simply by using fuzzy inference sytem.

Judul: Prospek pengembangan wilayah Propinsi Sulawesi Utara dilihat dari sektor pariwisata bahari
Abstrak: Tujuan penelitian untuk memperoleh gambaran yang jelas tentang sumbangan ekonomi sektor pariwisata bahari Bunaken dalam pembangunan daerah. Tujuan lain ialah untuk melihat sampai sejauh mana dampak sosial ekonomi. masyarakat. Lama tinggal wisatawan asing selama enam hari dengan pengeluaran rata-rata sebesar $ 59 616 perorang/hari. Pola penyebaran pengeluaran wisatawan asing lebih banyak menumpuk pada pengeluaran akomodasi (27,19%) dan diving (61,56). Lama tinggal rata-rata wisatawan domestik selama satu hari dengan pengeluaran rata-rata Rp. 8.270,- perorang/hari. Pola penyebaran pengeluaran wisatawan domestik dalam kawasan wisata bahari Bunaken untuk akomodasi (46,10%). Perbedaan penyebaran pengeluaran wisatawan asing dan wisatawan domestik terletak pada penggunaan alat penyelam. Pendapatan sektor pariwisata bahari Bunaken pada tahun 1987 mengalami kenaikan dibandingkan dengan tahun 1986. Kontribusi kenaikan sektor pariwisata bahari 6%, karena jumlah kedatangan wisatawan semakin meningkat dengan dibukanya jalur penerbangan Internasional Jakarta-Denpasar-Manado-Guam, Pendapatan pemerintah daerah dari sektor pariwisata bahari dalam bentuk retribusi belum ada. Perbandingan pengeluaran rumah tangga dengan indikator Good Service Ratio (GSR) menunjukkan bahwa pengeluaran rumah tangga untuk kebutuhan pokok lebih besar dari pada pengeluaran untuk kebutuhan jasa relatif lebih besar. Ini berarti tingkat kesejahteraan keluarga rendah, Sektor pariwisata adalah bagian dari pengembangan wilayah Sulawesi Utara berdasarkan indikator pendapatan yang merupakan sektor basis, dan pelipat gandaan pendapatan jangka pendek 9,09% dimana setiap Rp.1 pendapatan sektor basis akan menghasilkan Rp. 9,09 pada total pendapatan daerah. Sumbangan sektor pariwisata bahari cukup berarti dalam pertumbuhan dan pengembangan perekonomian wilayah Propinsi Sulawesi Utara, dan prospek dalam pertumbuhan pendapatan serta kesempatan kerja.
