Judul: Fair Profit Sharing System between Fishermen and Boat Owners in Drift Gillnet at Karangantu Fishery Port
Abstrak: Kesejahteraan nelayan bergantung pada pendapatan dari hasil produksi operasi penangkapan ikan yang melewati sistem bagi hasil. Pendapatan nelayan jaring rampus rendah diduga sebagai akibat dari sistem bagi hasil yang belum berkeadilan. Tujuan penelitian ini untuk mendeskripsikan kondisi bagi hasil saat ini, menganalisis pendapatan pemilik kapal dan nelayan, serta merumuskan sistem bagi hasil alternatif dengan mensimulasikannya melalui evaluasi UMP dan mempertimbangkan beban kerja, yaitu jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Penelitian dilakukan 29 Januari - 7 Februari 2024 dengan sampel penelitian sebanyak 22 kapal menggunakan metode purposive sampling. Hasil penelitian menunjukkan sistem bagi hasil saat ini 50% pemilik kapal dan 50% nelayan. Namun, pendapatan ABK saat musim sedang Rp 2.424.048 tidak mencapai UMP Banten Rp 2.661.280 dan mengalami kerugian saat musim paceklik. Oleh karena itu, diperlukan sistem bagi hasil alternatif dengan pertimbangan jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Hasil penelitian diperoleh proporsi 37% pemilik kapal dan 63% nelayan. Proporsi jaring rampus tersebut menunjukkan pendapatan nelayan saat musim sedang Rp 3.054.300 di atas UMP dan pendapatan bersih pemilik kapal Rp 7.222.605 tetap mendapat keuntungan Rp 4.584.461 di atas BEP. Namun, musim paceklik tetap mengalami kerugian sehingga dibutuhkan strategi pekerjaan alternatif saat musim panceklik pada penelitian berikutnya.

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%.
