Judul: Stabilitas Statis dan Dinamis Kapal Purse seine di Pelabuhan Perikanan Pantai Lampulo Kota Banda Aceh Nanggroe Aceh Damssalam (NAD).
Abstrak: Purse seiners are the most dominant type of fishing boat at Lampulo fishing ~rt, Banda Aceh, Nanggroe Aceh Darussalam. These fishing boats are operated \WJthe Exclusive Economic Zone of Indonesia but generally in a short period of thne (3 -6 days per trip). Such Sh011 trip duration is probably due to lack of boat L bility. The objective of this research was to calculate and to determine the ~bility of the fishing boats. Atadroe,one of the fishing boats, was used in this £search. This boat has ratios of its principle dimensions as follows: LIB = 3,93; ~D = 11,10; BID = 3,05. The LIB and BID are within ranges of standard values ~r purse seiners. The coefficients of fineness of the boat are as follows: Cw = ~8 3; Cvp = 0,58; Cp= 0,61; C® = 0,76; and Cb 0,46. Such coefficients indicate that Atadroe has a slim hull that makes less water resistance which enables the i>at to move at high speed. On the other hand, KM Atadroe has a fish hold with inall capacity and less maneuverability. A series of analysis on static and ~amic stabilities with 5 load conditions and 3 load positions concluded that the ~at has a good stability with positive righting arms and all of its stability ~rameters comply with the IMO standard criteria. However, the rolling period of tie boat ranges from 3,02 - 3,18 seconds which are shorter than the standard ~lues (5,5 - 7 seconds). Its rolling period indicates that the boat does not comply !lth the standard working condition for a fishing boat. The boat can be moved in lifld out in both marine and riverine waters easily since its draft changes slightly within a range of 0,013 - 0,015 m.

Judul: Stabilitas statis kapal purse seine muncar (studi kasus pada dalah satu kapal purse seine di Muncar)
Abstrak: Kapal perikanan merupakan salah sat- bagian dari unit penangkapan ikan dan merupakan sarana apung utama yang berperan dalam proses operasi penangkapan ikan, salah satu faktor yang harus dimiliki oleh kapal ikan untuk mendukung keberhasilan dalam penangkapan ikan adalah stabilitas. Penelitian tentang stabilitas statis kapal purse seine Muncar ini bertujm untuk menentukan kualitas stabilitas statis kapalpurse seine. Penelitian ini dilakukan dengan menggunakan metode studi kasus. Data kapal purse seine ini diperoleh dari hasil penelitian yang telah dilakukan sebelumnya Analisis data dilakukan terhadap rasio dimemi utama kapal, parameter hidrostatis kapal dan terhadap kualitas stabilitas statis kapal purse seine. Dari hasil analisis rasio diperoleh nilai LIB, LID; B/D masing-masing 2,83; 8,50; 3,OO. ketiga nilai tersebut kemudian dibanding dengan acuan yang digunakan untuk kapal-kapal ikan di Indonesia maka ketiga nilai rasio tersebut berada pada kisaran nilai acuan yang berarti bahwa tahanan kapal bertambah, kecepatan menurun, kekuatan longitudinal kapal baik, dan stabiditas kapal baik tapi daya dorong kapal menurun. Hasil perhitungan parameter hidrostatis pada kapal purse seine yang diteliti menunjukkan bahwa nil& koefisien bentuk pada kapal tersebut adalah sebagai berikut : Cb = 0,65; Cp = 0,72; Cvp = 0,75; Cw = 0,86 dan; Cm = 0,90. Dari kelima nilai tersebut menunjukkan bahwa kapal purse seine yang diteliti memiliki tingkat kegemukan yang sesuai untuk kapal yang mengoperasikan alat tangkap aktif (encircling gear). Analisis yang ketiga dilakukan terhadap stabilitas statis kapal purse seine Muncar. Analisis ini diawali dengan perhitungan nilai stabilitas statis dengan menggunakan sofhare PGZ dan microsof7 excel. Kemudian hasil dari 7 kondisi operasional kapal dibandiingkan dengan kriteria FVR.

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
