Abstrak: Outboard engine is used by the majority of fishermen in Indonesia. Therefore, it is necessary to do research about performance of outboard engine. This research is conducted in PPI Pasauran Serang Banten. The objectives of this research to identify part of outboard engine, calculate with theorist method the best speed for outboard vessel in PPI Pasauran, and to calculate with theorist average amount of fuel that needed by outboard fishing vessel per trip in PPI Pasauran. Data analysis is being done with comparative-numeric between marine outboard engine and long shaft outboard engine. Outboard engine are consist of motor, shaft of propeller, propeller, and carburetor. Best theorist speed that used by PPI Pasauran Fishermen to operate marine engine outboard are 4,59-4,72 knot and to operate long shaft outboard engine are 4,04-4,27 knot. Theorist amount of fuel that needed by marine engine outboard fishing vessel are 40-60 liter per trip and theorist amount of fuel that needed by long shaft outboard fishing vessel are 6-12 liter per trip.

Judul: Keragaan Teknis Kapal Motor Tempel di PPI Pasauran
Abstrak: Informasi tentang keragaan teknis kapal di suatu daerah diharapkan dapat memberikan gambaran tentang kecenderungan dimensi dan bentuk dari kelompok kapal daerah tersebut. Oleh karena itu perlu dilakukan kajian yang terkait dengan jumlah dan karakter teknis sebuah kapal di suatu daerah tertentu. Dalam kajian ini, lokasi kajian terletak di PPI Pasauran, Serang, Banten. Tujuan dari penelitian ini adalah menghitung jumlah perahu motor tempel dan mengidentifikasi keragaan teknis perahu motor tempel di PPI Pasauran Serang Banten. Pendataan kapal dan pengukuran dimensi utama kapal dilakukan secara sensus. Adapun data yang dikumpulkan terdiri dari data jumlah kapal dan ukuran dimensi utama kapal. Berdasarkan hasil kajian diketahui bahwa jumlah perahu motor tempel sebanyak 80 unit yang terdiri dari 53 perahu motor tempel besar dan 27 perahu motor ketinting. Perahu motor tempel besar memiliki bentuk yang cenderung gemuk, adapun perahu motor ketinting cenderung berbentuk ramping.

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%.
