<![CDATA[Transportasi merupakan salah satu komponen yang mutlak penting bagi pencapaian tujuan pembangunan nasional masa kini dan mendatang. Berbagai studi telah menunjukkan bahwa negara-negara yang berhasil dalam pencapaian tujuan pembangunan adalah negara-negara yang memiliki sistem transportasi yang memadai dalam memenuhi kebutuhan dinamis penduduknya. Angkutan laut atau pelayaran merupakan bagian dari transportasi yang tidak dapat dipisahkan dengan sarana transportasi lainnya. Di Indonesia terdapat dua kelompok besar penyelenggara transportasi laut, yaitu oleh pemerintah dan swasta. Masing-masing kelompok terbagi dua, di pihak pemerintah terbagi menjadi BUMN pelayaran yang menyelenggarakan transportasi umum dan BUMN non pelayaran yang hanya menyelenggarakan pelayaran khusus untuk melayani kepentingan sendiri. Sedangkan untuk pihak swasta terbagi menjadi perusahaan besar dan perusahaan kecil (termasuk pelayaran rakyat). Atas dasar tersebut dalam penelitian ini, peneliti mengangkat judul Faktor-faktor yang mempengaruhi Implementasi Kebijakan Transportasi Laut Di PT. Pelayaran Bahtera Adiguna (PT.Bag.)

<![CDATA[Commercial ships are a means of transportation at sea. For ships that do not exchange ballast water accordingly, it can be dangerous for the port environment they enter. The purpose of this research is to determine the metal content in the ballast tank water of commercial ships that have not implemented ballast water exchange in the middle of the sea following the rules of the International Maritime Organization (IMO). Research on the content of heavy metals in the ballast water of commercial ships, both ferries and cargo ships docked at the port, has been carried out using the AAS (Atomic Absorption Spectroscopy) method on flame. The results showed that the Pb content in ballast water ranged from 0.004-1.65 mg/liter, Cd ranged from 0.0015-0.47 mg/liter, Cu ranged from 0.0035-0.362 mg/liter and Zn ranged from 0.0015-2.54 mg/liter. According to the Decree of the Minister of the Environment Number 51 of 2004, the metal content of Cd and Zn has exceeded the seawater quality standards for water port, namely 0.001 mg/liter and 0.1 mg/liter, while the content of Pb and Cu has not exceeded the port quality standards.]]>

<![CDATA[The use of a pressure tank with a hydrophore tank that serves to temporarily store water, with the principle of providing air pressure on the upper surface of the water in the tank. Working pressure on hydrophore operation is a very important parameter for maximum operation. Problems that often occur in hydrophore tanks are usually from the supply pump, water level in the tank, air pressure, and pressure sensors. Problems caused by pumps include pump leaks, the presence of air in the water flow. As a result, the freshwater pump for supply to the hydrophore tank is often On-Off with a very fast time duration. This research was conducted to find the right setting to maintain stable operating pressure on the hydrophore tank. The research was conducted directly on board the MV. NORDTIGER with a case study of direct problems that occur in the freshwater distribution system on board. The variables at the time of data collection were the working pressure of the hydrophore tank pressure and the water level in the tank. The operating load used in data collection is the condition of ordinary load and full load. The results of the study on the performance of the hydrohore tank by varying the water-air level, working pressure range and final loading. The shortest duration of filling time is at 50%:50% volume level composition at a pressure of 5-7 bar, while the longest filling time is at 70%:30% water-air volume level at a pressure of 3-7 bar.]]>
