"The flat plate ship is a ship that is being developed and has entered the mass production stage of the Ministry of Research and Technology Republic of Indonesia. This is related to the function of flat plate vessels that are suitable with the conditions and needs of the Indonesian state, namely the massive production of marine fleets. Flat plate ships provide advantages including production cost efficiency which is far more economical than ships in general because it does not go through the bending process, so does the production time which can be shortened. But the flat plate ship still needs improvement, one of them is the ship propulsion.This study will combine a flat plate ship tunnel with a ducted propeller as an effort to increase thrust and hydrodynamic efficiency, with the ultimate goal of reducing fuel demand from flat plate vessels. The title of the research that was raised was the Analysis of the Combination of the Use of Tunnel and Ducted Propeller Against Increased Thrust on Flat Plate Ships: Trawler Fishing.The research method used is bollard pull / trawl pull using reference bollard pull guidelines - ITTC. Using a 70cm model ship with three configurations to be a comparison of the resulting value. The configuration used is conventional fishing trawler type flat plate without tunnel, and flat plate ship with Tunnel with all configurations using open and ducted propeller.This study succeeded in producing the desired destination with a combination of Tunnel and Ducted able to increase hydrodynamic efficiency and thrust values compared to other configurations. So that this research is expected to be one of the references to propulsion solutions and designs on flat plate vessels."

"The purpose of this study was to investigate the pattern, mean and differences of measurements between men and women on vertical dentocraniofacial cephalometric values of open bite subjects with anterior tongue thrust. There were 27 subjects between ages of 12-28 years, 6 men and 21 women of which thirteen vertical dentocraniofacial variables were obtained from measurements taken from lateral cephalometrics; ANS-Me, N-Me, S-Go, CC-Go, SN-MP, N-ANS, PP-MP, Y-axis, UPDH, LPDH, ANS-UI, LI-MP and overbite. The means of values of ANS-Me, N-Me, S-Go and CC-Go were compared with the norms based on Deouteromalay population and SN-MP, PP-MP, Y-axis, UPDH, LPDH, ANS-UI, LI-MP with the norms based on Caucasian population. The obstacle of this study was the unavailable norms of vertical dentocraniofacial cephalometric for Deuteromalay population. Generally the pattern of vertical dentocraniofacial of open bite subjects with anterior tongue thrust shows the long face syndrome."

"Anterior Tongue Thrust Swallow (ATTS), a swallowing pattern by pushing the tongue onto anterior dentition, can initiate malocclusion in the anterior region, which will create psychophysiological problems due to aesthetic, speech, and mastication disorders. The use of a Tongue Crib (TC) as a corrective device for ATTS is to block the force of tongue against the anterior teeth. Wearing a TC will have an experience of discomfort for the patient and can be an obstacle in using TC regularly, lengthening the period of treatment. A clinical trial with 25 subjects using TC in their retention period, and 48 patients only using Hawleyretainer without crib as control, was carried out from September 2004 until May 2005 in the FKG UI Orthodontics clinic, the Orthodontics Clinic of Lembaga Kedokteran Gigi (Ladokgi) TNI AL R.E. Martadinata and in a specialist clinic. The survival analysis for the TC users, associated with sensor time, indicates that 25 of the TC users had not succeeded to correct ATTS. A discomfort questionnaire (DQ) was specifically designed for this study, consisting of 9 items. A significant result was that the discomfort experienced was one of the risk factor for the ineffectiveness of Tongue Crib in correcting ATTS."

"Quadcopter berukuran kecil dan inersia drone yang rendah memungkinkan penggunaan sistem kontrol penerbangan sederhana, dengan kepraktisan Quadcopter diharapkan dapat dipergunakan untuk penanganan bencana sehingga dapat meningkatkan ketahananwilayah. Quadcopter yang dikeluarkan oleh perusahaan tidak dapat diubah-ubah. penelitian ini dengan merakit quadcopter sendiri dan melakukan perubahan pada pitch propeller untuk mengetahui pengaruh thrust dan thrust motor pada quadcopter tipe x. Dari hasilpenelitian dan perhitungan yang dilakukan, thrust yang dihasilkan dengan sudut puntir (pitch) 50olebih besar dibandingkan dengan sudut puntir (pitch) 43o pada setiap pergerakannya sehingga semakinbesar sudut puntir (pitch), maka semakin besar pula thrust yang dihasilkan oleh propeller tersebut. Voltage yang masuk pada setiap motor akan berbeda tergantung pada pergerakannya. Jadi, semakin besar voltage yang masuk pada motor brushless maka semakin tinggi putaran motornya sehingga thrust yang dihasilkan juga semakin besar."
