Abstract

Approaching time is usually used as one of indicator on evaluating the successful of piloting’sservice level of ship in main port in Indonesia. However, in many main ports in some countries, this method is no longer used. This study is aimed to determine the significancy of approaching time as a standard in evaluating the piloting’s service in Indonesia.The research has been conducted in the Port of Tanjung Priok, where involved the respondents of pilotage personnels, ship captains, helmsman, and also some retired pilotage personnels which formerly have worked as pilotage. The data were analized using AHP (Analytical Hierarchy Process), AHP will describe the problem as multi-factor complex into a structured and systematic so easy to understand. The results showedthat 56.59% of respondences agree the approaching time is still important as an indicator on evaluating the service of pilotage, while 43.41% of them thought that it needs more considerations to use the approaching time as an evaluation indicator. It is important to note approaching time since it is a measurable workface in a shipping port in conducting the piloting service. This is caused that the pilotages still depend on the availabilities of all tools such astug boat in which the quantity and its capacity must still be raised again.

Abstract

Lobster air tawar yang dipasarkan dalam keadaan mati, meskipun masih dalam keadaan segar,harganya turun hingga 50 % sehingga diperlukan suatu teknik transportasi khusus agar lobster air tawartetap hidup hingga ke tangan konsumen. Transportasi tanpa media air dapat menjadi pilihan untukdistribusi lobster air tawar dengan waktu yang lebih lama, khususnya untuk tujuan ekspor. Kapasitaspengangkutan dalam transportasi, khususnya ekspor, memiliki peranan penting. Penambahan rak dalamwadah pengemasan diharapkan dapat meningkatkan kepadatan tanpa mempengaruhi mortalitas komoditashidup yang diangkut. Penelitian dilakukan melalui tiga tahap, penelitian tahap pertama bertujuan untukmengetahui kualitas media air akuarium. Tahap kedua bertujuan untuk mengamati aktivitas lobster airtawar dan perubahan suhu media serbuk gergaji selama pengemasan. Tahap ketiga bertujuan untukmempelajari efektivitas penggunaan rak untuk meningkatkan kepadatan lobster air tawar dalamkemasan.Hasil penelitian tahap pertama menunjukkan bahwa analisis rata-rata kualitas air akuarium sudahmemenuhi persyaratan kelayakan kualitas air untuk lobster air tawar. Hasil penelitian tahap keduadiperoleh hasil bahwa lobster air tawar menunjukkan aktivitas pada saat suhu media mencapai 5 °C.Lobster bergerak mundur menaiki serbuk gergaji. Suhu media kemasan akan menurun hingga jam ke-4 dankembali naik hingga akhir penyimpanan pada jam ke-34. Hasil penelitian tahap ketiga menunjukkan bahwarak akrilik terbukti efektif sebagai bahan dasar pembuatan rak dengan kapasitas muat 7-8 ekor/rak dandapat meningkatkan kepadatan hingga 54 %. Penggunaan rak akrilik mampu menghasilkan kelulusanhidup lobster air tawar sebesar 100 % hingga 50 jam penyimpanan. Perlakuan durasi penyimpanan berbedapada penelitian ini tidak mempengaruhi tingkat kelulusan hidup lobster air tawar. Rak akrilik tidakberperan secara langsung dalam usaha untuk mempertahankan dormansi lobster air tawar namun dapatmengurangi pergerakan lobster air tawar dalam media pengemasan.Kata kunci: lobster air tawar, penyimpanan, rak

Abstract

Fish transportation is an activity on moving fish from one place to another. Specific for live fish, the transportation process is so important due to the different value of live fish and the dead one, either in term of its price and or function. Live fish transportation, basically is a forcing fish in a new environment condition different with the usual one, along with sudden changes of ambient characteristic which threat the live of fish. The factors which influential on fish live transportation are fish condition and water quality. Beside these, other factor which also give influent is infrastructure of transportation (road, vehicle, etc.). The researched was done to know the effect of road surface quality (good, semi good, and bad) on survival rate (SR) of Oreochromis niloticus fish juvenile. The highest SR came from the good treatment is 88.33%, with the water quality are: DO (dissolve oxygen)=2.19 ppm; CO2=39.6 ppm;pH=6.02; alkalinity = 156.42 ppm; and temperature = 27.75oC. The lowest one came from the bad treatment is SR=0% with the water quality are: DO (dissolve oxygen)=1.71 ppm; CO2=53.46 ppm; pH=6.02; alkalinity=1,003.86 ppm; and temperature=27.5oC. The SR of juveniel fish transportation at a real condition from Bogor to Jakarta is 93.3%. The result indicated that types and time of treatment effected to the SR.Key words : infrastructure of transportation, fish transportation, survival rate
