Evaluasi Pengiriman Video Menggunakan Pengkodean Skalabilitas Spasial dengan Gangguan pada Kanal Internet

Video transmission over the internet can be a great possibility of the existence of lost packets (packet loss) and load variations in a large bandwidth. This is a source of network congestion can interfere with the rate of data communication. In this paper the proposed planning optimal error control in scalable video transmission to a video coding technique FGS (Fine Granularity Scalability), which is an improvement on the MPEG-4 video coding, which has outputs are scalable base layer and layer Enhanchement that have different sizes and rates, which the application will be adapted to the transmission network conditions, the ultimate goal is to minimize any distortion from the source to the destination. In the simulation yields a value Peak Signal to Noise Ratio (PSNR) on the base layer of 29, 683 dB and 78,917 dB enhancemenet layer and the base layer for the MSE of 69,998 dB and 0,000834417 dB enhancemenet layer, Means Square Error (MSE) as the performance of the network system performance on video quality for both the base layer and layer Enhanchement

Konversi Energi Panas Penggerak Utama Kapal Berbasis Thermoelectric

Energi sudah menjadi salah satu kebutuhan yang tidak dapat dipisahkan dalam segala aktivitas manusia. Energi saat ini dapat diperoleh dari sumber daya alam seperti minyak bumi yang telah ada dan juga dengan memanfaatkan gejala alam sebagai tenaga penggerak untuk memperoleh energi. Namun ketidakseimbangan antara kebutuhan energi dan energi yang tersedia saat ini membuat manusia berfikir untuk membuat energi alternative lainnya. Tidak terkecuali dalam dunia perkapalan, salah satunya yang kemudian diangkat dalam skripsi ini adalah memanfaatkan energi panas buangan mesin penggerak utama kapal sebagai sumber energi terbarukan dengan menggunakan metode konversi energi (thermoelektric). Thermoelectric merupakan metode konversi energi yang memanfaatkan perbedaan temperatur untuk menghasilkan energi listrik dengan memanfaatkan prinsip kerja peltier. Pada penelitian ini digunakan beberapa peltier yang disusun secara seri maupun parallel pada kondisi putaran mesin variasi mulai dari 1000 RPM sampai 2500 RPM yang bertujuan untuk mengetahui besar energi listrik yang dapat dihasilkan dari perbedaan temperature pada panas mesin utama kapal hasil pembakaran yang terbuang dengan suhu kamar mesin. Hasil penelitian ini menunjukkan bahwa sebuah peltier mampu menghasilkan maksimal daya pada kondisi putaran mesin 2500RPM dengan perbedaan suhu 33 ºC sebesar 1,12 Watt, dan susunan 2 buah peltier dirangkai seri memiliki daya yang lebih besar dibandingkan susunan peltier secara parallel pada kondisi putaran mesin yang sama yaitu sebesar 8,4 Watt. Ini menunjukkan sinkronisasi antara perbedaan suhu yang terjadi pada kedua sisi peltier dengan daya listrik yang dihasilkan pada peltier

Simulation of sub-drains performance using visual MODFLOW for slope water seepage Problem

Numerical simulation technique was used for investigating water seepage problem at the Botanic Park Kuala Lumpur. A proposed sub-drains installation in problematic site location was simulated using Modular Three-Dimensional Finite Difference Groundwater Flow (MODFLOW) software. The results of simulation heads during transient condition showed that heads in between 43 m (water seepage occurred at level 2) until 45 m (water seepage occurred at level 4) which heads measurement are referred to mean sea level. However, elevations measurements for level 2 showed the values between 41 to 42 m from mean sea level and elevations for level 4 between 42 to 45 m from mean sea level. These results indicated an increase in heads for level 2 and level 4 between 1 to 2 m when compared to elevations slope at the level 2 and level 4. The head increases surpass the elevation level of the slope area that causing water seepage at level 2 and level 4. In order to overcome this problems, the heads level need to be decrease to 1 until 2 m by using two options of sub-drain dimension size. Sub-drain with the dimension of 0.0750 m (diameter), 0.10 m (length) and using 4.90 m spacing was the best method to use as it was able to decrease the heads to the required levels of 1 to 2 m

The results showed that the combination of MS medium + 2 ppm 2,4D + 3 ppm BAP (W2) is the best medium to induce callus, marked by green callus, compact callus (friable), and the highest wet weight of callus 0.0203 g

Modelling Maintenance System of a Fishing Vessel Using Markov Process Method

Reliability analysis on a ship system have developed as the increasing demand on the level of safety and reliability of the ship design. There are some significantly important of ship systems which support the ship operationalization. Failure on one system component can influence the functionality of the respective system and even can damage the whole ship function. If this is happen, the safety of the passengers and cargoes on the ship will be threatened. A comprehensive evaluation on the ship systems must be conducted so that the failure level of the system can be predicted. For the safety of the maintenance action on a system, model of the ship system maintenance must be designed. One common approach to be used on a maintenance modelling of a system is markov approach or markov modelling. The final result of the appoach is an availability index of a system as a consequences of the ship system maintenance. Output from this approach will become input for designing ship system maintenance strategy. This paper discusses the use of markov process approach in modelling maintenance of a ship system. In the final part of the paper, a maintenance modelling case for a ship fresh water cooling system is presented
