Publisher : Direktorat Riset dan Pengabdian Masyarakat (DRPM), ITS

Kapal penumpang KM. Labobar membutuhkan air bersih. Air bersih akan tersedia jika kapal dalam keadaan bersandar di pelabuhan karena pada saat itu dilakukan pengisian air bersih yang ada di kapal. Jika kebutuhan air tawar di kapal penumpang KM. Labobar meningkat maka air limbah domestik gray water (non consumable) akan juga meningkat. Limbah pada dasarnya harus melalui suatu proses treatment agar nantinya limbah tersebut aman pada saat dibuang ataupun saat digunakan lagi. Proses treatment dilakukan untuk menghindari pencemaran laut dan menurunkan kualitas air laut. Adanya permasalahan tersebut maka harus dilakukan recycle yaitu suatu pengolahan kembali pada sistem pembuangan limbah gray water dengan menggunakan teknik koagulasi. Treatment ini dilakukan agar dapat menghemat kebutuhan biaya serta menghemat pengisian air tawar pada kapal. Koagulasi merupakan suatu proses destabilisasi partikel koloid dan kemudian mengendap selama selang waktu tertentu. Pembahasan yang ada pada tulisan ini meliputi mendesain sistem pengolahan air limbah, memodifikasi existing system dan general arrangement yang ada pada KM. Labobar, perhitungan biaya dari sistem pengolahan serta menganalisa kelayakan ekonomis jika sistem ini di aplikasikan di KM. Labobar. Berdasarkan analisa data dapat dibuat tangki treatment sebanyak 2 pada frame 70-75, treatment ini akan menghasilkan sebanyak 100,758 m3 setiap harinya. Selain itu dibuat 2 tangki holding tank pada frame 132-142 yang bisa menampung sebesar 14,4 m3 setiap tangki. Dilakukan juga analisa ekonomi menggunakan sistem Payback Period, yang akan mengalami keuntungan pada saat menginjak tahun kedua.

For 90% of world trade is carried by shipping industry. In Indonesia, highly concentrated goods movement are reported in Java and Sumatera which leads Tanjung Perak, Surabaya to become second largest ship terminal after Tanjung Priok, Jakarta. As the loading and unloading process is on call, any kinds of wastewater are continuously being discharged (sludge, oily sludge, blackwater and greywater). All wastewater if continuously discharged without any proper treatment is harmful to both human and aquatic environment. Especially in Indonesia and northern part of Java island where marine tourism is growing but in the other hand, also the home of largest ports. The purpose of this research is to design a fixed, compact discharge water treatment plant in one pilot international terminal, Terminal Petikemas Surabaya. The capacity of each discharge water receiver and treatment is determined according to ship’s arrival data. Based on the data analysis, the capacity of sludge receiver is 25 m3/day, oily bilge receiver for 200 m3/day, blackwater for 10 m3/day and greywater for 20 m3/day. Hereinafter, through the literature review of various kinds of wastewater treatment, a fixed and compact port-based discharge water treatment plant is designed by combining Membrane Bioreactor (MBR) for greywater, centrifugation for sludge, combination of ultrafiltration and reverse osmosis for oily bilge and Source Separation Sanitation (SSS) for blackwater where each effluent of the treatment can be used for one another. Furtheremore, an initial cost of the designed port-based discharge water treatment plant is conducted, resulting in total of IDR 22,487,086,876. The payback period (PBP) of the plant is 4 years.

In the process of distributing LPG to all regions in Indonesia, LPG stations have an important role. In operation, LPG stations may have hazards caused by environmental conditions such as pipe fatigue (fatigue) due to geotechnical forces or failure of components in the system. Research case of piping systems used pipe stress analysis. The purpose of this analysis is to know the deflection of the pipe, the loads that occur by the pipe, and the safety of the pipe and its support. This analysis refers to the code or standard ASME B31.3 where the stress analysis is performed using software. In the process of pipe modeling, there are variations of loading such as pressure load variation, wall thickness and elevation of soil degradation value. From the results of calculation and simulation pipe stress analysis using software can be seen that header pipe 12 inch at LPG station of Semarang is NOT stress, so it is safe to be use. The thickness of the pipe allowed for to be unstable when the operating pressure is greater than 0.15 inch, and the operating pressure allowed for the pipe to be unstable at a thickness of 0.4 pipe (schedule 40) is less than 725 Psi (50 Bars).

The thermal oil system is one type of heater that widely used on ships. The system is an important system used to heat fuel that will be used for the operation of the main engine, auxiliary engine, and boiler. This system has been installed on 17500 LTDW Product Oil Tanker, MT. Parigi, but not yet tested so that it does not know whether the system is able or not to transfer heat from heating equipment (boiler and economizer) to each fuel tank in accordance with the desired value. Therefore, this research performs an engineering evaluation in term of heat transfer analysis to ensure that the heat transfer process of thermal oil from heating equipment to the fuel tanks is already meeting the required temperature or not. This analysis is done by using thermodynamic equation, namely heat balance equation and heat loss equation. The result shows that the heat transfer of thermal oil to each fuel tank corresponds to the desired value, namely 180oC for the thermal oil inlet temperature to each fuel tank and 140oC for the thermal oil re-enter temperature to the heating equipment.

Noise Reduction in Ship Engine Room by Optimisation of Muffler Design Sunarsih Sunarsih; Taufik Fajar Nugroho; Mirfak Yunan Navyazka

Noise level onboard, particularly in the engine room, requires a careful monitor to not causing any disruption or discomfort to the shipboard environment. For monitoring purposes, an appropriate alternative system can be applied if the noise level exceeds the limit set by applicable regulations such as IMO, ABS, and LR. The current research uses computational methods to map noise contours in the engine room and recommends some muffler models to reduce the noise level in the MV Natuna Express engine room. Based on the field measurement, the noise level exceeds the Standards value at a maximum of 110 dB. Mapping and designing of the muffler models were based on the measurement data. Simulation results show that greater transmission loss hence noise reduction is affected significantly by the expansion of muffler chamber length and diameter. Modification of the muffler chamber using plywood and the tailpipe on both ME ON Generator ON and ME OFF Generator ON conditions respectively reduce the noise approximately by 24.94 dB and 10.50 dB.
