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: Suitability of Ship Dimensions and Engine Power Used by Small Scale Fishing Vessels at Palabuhanratu Fishing Port
Abstrak: Bahan bakar menjadi komponen penting dalam operasi penangkapan ikan di Palabuhanratu, namun tingginya harga bahan bakar menjadi beban bagi nelayan dan pemilik kapal. Untuk menghemat biaya operasional, perlu dilakukan evaluasi kesesuaian dimensi kapal perikanan dengan daya mesin yang digunakan. Tujuan penelitian ini adalah mengevaluasi kesesuaian dimensi kapal dengan daya mesin yang digunakan serta kebutuhan bahan bakar operasi penangkapan ikan. Pendekatan yang dilakukan adalah dengan membandingkan daya mesin yang digunakan dengan kebutuhan daya mesin teoritis dan antara jumlah bahan bakar yang dibawa saat trip penangkapan dengan kebutuhan bahan bakar teoritis. Hasil penelitian menunjukkan bahwa mesin yang digunakan oleh mayoritas kapal skala kecil di PPN Palabuhanratu masih terlalu besar dari kebutuhannya, kecuali pada kapal kayu yang menggunakan motor tempel 40 PK. Nelayan cenderung membawa bahan bakar lebih banyak dibandingkan dengan kebutuhan bahan bakar teoritis dengan rata-rata sebesar 62,1%. Selain karena menggunakan ukuran mesin yang lebih besar dari yang seharusnya, hal ini juga disebabkan oleh kecenderungan nelayan menyediakan BBM cadangan selama operasi penangkapan ikan., Fuel is an important component in fishing operations in Palabuhanratu, but the high price of fuel is a burden for fishermen and boat owners. To save operational costs, it is necessary to evaluate the suitability of fishing vessel dimensions with the engine power used. The purpose of this study is to evaluate the suitability of vessel dimensions with the engine power used and the fuel requirements of fishing operations. The approach taken was to compare the engine power used with the theoretical engine power requirements and between the amount of fuel carried during the fishing trip with the theoretical fuel requirements. The results showed that the engines used by the majority of small- scale vessels in PPN Palabuhanratu were still too large for their needs, except for wooden vessels using 40 PK outboard motors. Fishermen tend to carry more fuel than the theoretical fuel needs with an average of 62.1%. In addition to using a larger engine size than necessary, this is also due to the tendency of fishermen to provide spare fuel during fishing operations.

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%.
