Abstract

Indonesia merupakan sebuah negara kepulauan terbesar di dunia dengan panjang garis pantai mencapai 99.093 kilometer dengan sumber daya ikan yang melimpah. Untuk memaksimalkan hasil tangkapannya, sebagian nelayan di Indonesia menggunakan cahaya untuk mengumpulkan ikan sebelum ditangkap. Salah satu jenis kapal ikan yang memanfaatkan cahaya lampu dalam proses penangkapan ikan adalah kapal purse sein. Pada penggunaan lampu petromaks, cahaya yang dihasilkan lebih redup dan tidak dapat menembus air laut sampai kedalaman 5 meter. Cahaya lampu yang diletakkan di atas permukaan air pun 70%-nya dipantulkan kembali ke atas oleh permukaan air. Untuk mengatasi hal itu, saat ini di pasaran banyak dijual lampu pengumpul ikan yang dicelupkan dalam air. Namun, proses ini beresiko tinggi karena pengaruh angin dan arus laut akan membuat lampu tersebut susah diatur ditempat yang diinginkan. Warna cahaya dari lampu pengumpul ikan yang ada saat ini tidak bisa menarik ikan-ikan yang memiliki jenis kepekaan warna yang berbeda, karena jenis warna dari lampunya hanya satu jenis. Untuk mengatasi masalah tersebut, maka diperlukan sebuah lampu pengumpul ikan yang dapat dikendalikan dari jarak jauh dengan warna cahaya yang beragam. Lampu pengumpul ikan tersebut dapat dikendalikan sampai jarak 120 meter serta dapat mengumpulkan ikan nila dengan penggunaan cahaya warna merah.

Abstract

Monkasel monument is one of Surabaya's landmarks and will become "The Central Business District Riverbank". In this area has been built many recreational facilities, namely the statue of Suro and Boyo, Plaza Area, BMX Area, Tribune Area, Skate Park Area and Food court Ketabang. However, the development of water tourism in this area is still not optimal. One to overcome this is the need to develop a floating restaurant that can integrate all existing facilities, especially the food court. The development of this floating restaurant has multi-function, which is increasing the visitor of the food court, because this floating restaurant only provides a place to eat not sell food, as a place of business transactions and in the long run will improve the water quality of Kalimas river. This floating restaurant is designed with high comfort and safety, and environmentally friendly, so that all the functions can be accommodated well. This is because the floating diner is a catamaran boat that has a low sweep wave and uses solar panels

Abstract

Total Suspended Sediment (TSS) and Chlorophyll-a (Chl-a) are globally knows as a key parameters for regular seawater monitoring. Considering the high temporal and spatial variation of water constituent, remote sensing technique is an efficient and accurate method for extracting water physical parameter. A high accurate estimated data derived from remote sensing depends on an accurate atmospheric correction algorithm and physical parameter retrieval algorithms. In this research, we evaluated the accuracy of atmospheric corrected product of NASA as well as develop algorithms for estimating TSS and Chl-a concentration over Poteran and Gili Iyang island water using Landsat-8 OLI data. The data used in this study was collected from Poteran’s waters (9 stations) on April 22, 2015 and Gili Iyang’s waters (six stations) on October 15, 2015. Low correlation between in situ and Landsat Rrs(λ) (R2= 0.106) indicated that atmospheric correction algorithm performed by NASA has a limitation. The TSS concentration retrieval algorithm produced acceptable accuracy both over Poteran’s Waters (RE of 4.60% and R2 of 0.628) and over Gili Iyang’s waters (RE of 14.82% and R2 of 0.345). Although the R2 lower than 0.5, the relative error was more accurate than the minimum requirement of 30%. Whereas, The Chl-a concentration retrieval algorithm produced acceptable result over Poteran (RE of 13.87% and R2 of 0.416) and failed over Gili Iyang’s waters (RE of 99.140 and R2 of 0.090). The low correlation between TSS or Chl-a measured and estimated TSS or Chl-a concentration were caused not only by performance of the developed TSS and Chl-a estimation retrieval algorithm but also the effect and accuracy of atmospheric corrected reflectance of Landsat product.

Abstract

Basically a ship has a variety of conditions, namely cargo handling, anchoring, maneuvering, and sailing its requires large electricity consumption. The quality of the voltage is not good will cause damage to electrical equipment on board. Disturbances that occur in electrical system of MT. X may result in a decrease in the performance of existing electrical equipment on the vessel and affect a certain condition as in loading-unloading conditions the time required for loading and unloading becomes longer due to interference with the electrical system. The MT.X tanker system has 5 (five) main busbars: BUS 1, FEEDER PANEL, DSB 2, DSB 3 & 4, and DSB 6. The MT tanker. X has a generator of 3 units with a power of 680 kw each, a frequency of 60 hz and a voltage of 450 V. Transient disturbance analysis under loading-unloading condition occurs transient response due to starting ballast pump where the voltage rises and then drops within 0.5 seconds with the highest value of 100.44% at 4.01 seconds and the lowest value is 99.50% to 4.81 can then reach steady state conditions at 99.9%, which does not exceed the IEEE standard limits. In harmonic disturbances under loading-unloading conditions, in the feeder panel connecting the harmonic source with load at the 5th order, the value of VIHD is 8.77%, which exceeds the IEEE standard of 5%. While the value of VTHD in loading and unloading conditions also exceeded the predefined standard limits. After installation of the filter, it can be seen that the value of VIHD at the 5th order in loading-unloading condition decreased to 3.6% after the installation of filter on feeder panel, or equal to decrease as much as 5.17%. The decline in the value of VIHD has fulfilled the IEEE 519-2014 standard of 5% on each individual order. Meanwhile, VTHD value in loading-unloading condition also decreased, from 11.18% to 7.02%.

Abstract

Fuel is one of the important component of ship operations. The overall operating cost of the vessel, approximately 60% consists of fuel costs. The unavailability of fuel causes the ship's operational processes to be adversely affect the company from both technical and material terms. It is a bad condition if ship’s fuel does fulfilled the time schedule. To reach the fuel operation criteria and help ships crew operate the fule system, we propose the method to control fuel system. Our objection is how to make ship fuel system can be operated automatically as well as temperature control system on the vessel using PLC. This automation system relies on high level sensors and low level sensors as well as temperature sensors in each tank to trigger the performance of each of the fuel system support equipment such as pumps, valves, heaters. The sensor and thermometer in the tank will be processed by the PLC prior to controlling the equipment. Processing is sequentially adjusted to the processing sequence of HFO fuel. Processing is done based on existing ship data but still using the control manually. As well as recommendations from the classification bureau and machine manufacturers. The work process of the system can be monitored as a whole through Human Machine Interface. The monitor consists of a view that contains all the work of the existing system. The PLC used is OMRON CPM2A with CX-Programmer software and CX-Designer monitor. So by simply using a control device in the form of PLC, HFO processing can be operated automatically both when the ship is idle or in sail condition
