2 BACK GROUND GT is not comparable with the actual physical form GT is not comparable with the actual physical form standard formula  Un-valid data of fishing vessel  Loss of non-tax revenue  Losses for ship owner  Un-valid data of fishing vessel  Loss of non-tax revenue  Losses for ship owner The polemical of GT calculation GT =( Vb + Va) x 0,353, or GT =( Vb + Va) x 0,25 Avarage 76%, Survey 2008 94%, Statistik Perikanan 2010 BPK-RI, 2009 Markdown case Markdown case Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

3 OBJECTIVE Guiding the right measurement of each dimensions Creat a simple formula for GT calculating base on LOA Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

4 METHODS directly survey on the same type of vessel to take the dimension of LOA, L deck, breadth of mid ship, and depth 487 units purse seiner, 2008 Analysis Standard Formula : GT = V x 0,353 or GT = V x 0,25 (Vb + V superstructure) x 0,353 {(LxBxDx Cb) + (l x b x h)} x 0,353 Nomura &Yamasaki, 1975 Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

5 METHODS directly survey on the same type of vessel to take the dimension of LOA, L deck, breadth of mid ship, and depth 487 units purse seiner, 2008 approachs Assumsion: the same type of vessel, above 10 GT Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

6 Analysis Standard Formula : GT = V x 0,353 or GT = V x 0,25 (Vb + V superstructure) x 0,353 {(LxBxDx Cb) + (l x b x h)} x 0,353 Nomura &Yamasaki, 1975 Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

13 RESULT L 0 = 0.90 LOA B 0 = 0.21 LOA D 0 = 0.07 LOA Volume below deck: Volume superstructure: Va = 0.26 Vb Simple Formula : BASE on LOA Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

14 Relation between standard formula and simple formula Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

15 Deviation between standard formula and simple formula d = 0.03870 ~ 0.04 Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com

16 CONCLUSION 1.GT calculation using simple formula Based on LOA is closer to actual GT, it’s indicated by the value of R 2 = 98% 2. If you want to replicate this formula, you should take a few examples of the dimensions of the vessel first. CONCLUSION 1.GT calculation using simple formula Based on LOA is closer to actual GT, it’s indicated by the value of R 2 = 98%, d = 0.03870 ~ 0.04 = ± 4% 2. If you want to replicate this formula, you should take a few examples of the dimensions of the vessel first. Seminar Nasional Perikanan Tangkap 6, Oktober, 22-10, 2015 denisoeboer@gmail.com
