THE KEY SUCCESFULL OF Extension Service On Thailand Durian Performance To The World Market
No full textThis book will not only tell about the keys to the success of Thailand in cultivating durian, but also durian marketing. It does not only contain the author's personal experiences while in Chanthaburi Province but also contains statistical data that supports the statement, as well as other reliable sources. This book is the result of an internship program that has been carried out by the author while in Thailand, especially in Chanthaburi Province, Office of Agricultural Research and Development Region 6 Chanthaburi Province. An internship program was carried out to increase knowledge and experience of agricultural conditions in Thailand which is known to be advanced. The author would like to thank Assoc. Prof. Am On Aungsuratana as the main supervisor during the program in Thailand and Dr. Rapee Dokmaithes. In addition, thanks are also conveyed to all staff and parties involved while the author is in OARD Region 6 so the author can run and complete the internship program smoothly, as well as write about their success in developing durian in Thailand. In addition, the authors also thank the University of Jember for all the knowledge provided. I would also like to thank my father (alm) Irfan Boedi Setiawan S.P., my mother Mrs. Dr. Asrumi, M.Hum, and younger brother Firnanda Pulung Wibowo, S.P., for all their enthusiasm and motivation. Finally, the author would like to thank to beloved husband, Sabran, S.K.M., M.P.H. and lovely son Randika Arung Naradipta for all the support given during the writing of this book. The last happy reading and hopefully useful
Perancangan Sistem Kontrol Sandar Kapal Otomatis Berbasis Logika Fuzzy di Pelabuhan Tanjung Perak Surabaya
Full text linkTugas akhir ini berkaitan dengan perancangan simulasi sistem kontrol sandar otomatis dengan jenis kapal AHTS (Anchor Handling Tug Supply). Sistem auto pilot yang digunakan dalam simulasi ini menggunakan Kontrol Logika Fuzzy (KLF) Sugeno-Takagi. Kontrol Logika Fuzzy digunakan untuk kontrol kemudi (rudder), stern thruster, dan bow thruster selama proses sandar kapal. Simulasi ini menggunakan data dari spesifikasi kapal yang sebenarnya dan menggunakan model pendekatan Nomoto orde II. Agar hasil simulasi mendekati kondisi yang sebenarnya, dilakukan pemodelan arus laut dengan kecepatan arus sesuai dengan kondisi di pelabuhan Tanjung Perak. Hasil penelitian menunjukkan bahwa simulasi sistem kontrol sandar kapal otomatis dapat mengikuti trayektori (set point) yang telah ditentukan dan mempertahankan posisi heading sandar kapal. Dengan error trayektori antara jalur yang ditentukan dengan jalur sebenarnya jika tidak ada gangguan arus laut maka root square error maksimum trayektori sebesar 0.39 m. Dengan adanya gangguan arus laut 2; 2,25 dan 2,5 knot root square error maksimum trayekori sebesar 1,26; 0,64 dan 2,68 m. Sedangkan untuk tahapan sandar kapal arah kapal dengan gagguan arus laut 2; 2,25 dan 2,5 knot menghasilkan error sebesar -0,110; -0,060 dan -0,030. Waktu yang ditempuh untuk sandar kapal tanpa ada gangguan selama 668 detik, dengan adanya gangguan arus 2; 2,25 dan 2,5 knot berturut-turut selama 113, 96, dan 99 detik

Auto Berthing – a Solution for Achieving Zero Waiting Time at Harbour
Full text linkTanjung Perak Port is one of biggest harbour in Indonesia. The shipping start from Karang Jamuang to Naval Base. The moving is use help of scout ships and tug boat. A control system can be applied to anchored ships , to replace the role of tug and scout boat. Movement from the parking position to the anchored involve auto maneuver and auto berthing. Both auto system is designed using fuzzy logic control. Input of control from sensors and guidance according to the path leading to the dock, and to anticipate the environmental disturbance factors (that is ocean currents). Control rules are unique, according to the type and size of vessel. In the case study to AHTS vessels, berthing auto show good ability. The heading error of 0.04° to the direction parallel to the dock, and the range of distances error is 0.16 to 2.16 meters from the desired position. Reduction of processing time leaning point to Jamrud dock is 33 minutes
