Judul: Deteksi Kapal Purse Seine di WPP 711 Menggunakan Data Vessel Monitoring System (VMS)
Abstrak: Upaya menjalankan konservasi kelestarian sumberdaya alam sangat penting untuk dilakukan seperti pengelolaan dan pengawasan bagi armada kapal penangkapan. Tentu dalam menjalankan hal itu, diperlukan suatu teknologi yang dapat mendeteksi jumlah kapal yang banyak dalam satuan wilayah yang luas. Tujuan dari penelitian ini yaitu untuk mengetahui jumlah deteksi kapal dan pola distribusi kapal. Metode yang digunakan pada penelitian ini yaitu dengan metode deskriptif, menggunakan data posisi, nomor identitas kapal, dan kecepatan kapal. Selanjutnya data tersebut ditampilkan, sehingga terlihat sebaran aktivitas kumpulan kapal. Hasil menunjukan bahwa aktivitas tertinggi berdasarkan waktu terjadi peningkatan jumlah deteksi pada malam hari yaitu sebesar 34% dan terendah terjadi pada siang hari yaitu sebesar 17%. Jumlah deteksi terbanyak terjadi pada musim utara pada bulan September yaitu sebesar 653 dan terendah yaitu terjadi pada bulan Januari 63 kapal., Efforts to carry out the conservation of natural resources are very important to do, such as management and supervision of fishing vessels. Of course, in doing so, we need a technology that can detect a large number of ships in a large area unit. The purpose of this study is to detect the fishing vessel distribution patterns detected from the VMS data. The method used in this research is descriptive method, using position data, ship identity number, and ship speed. Furthermore, the data is displayed so that it can be seen the distribution of ship collection activities. The results showed that the highest activity based on time was an increase in the number of detections at night, which was 34% and the lowest occurred during the day at 17%. The highest number of detections occurred in the east monsoon in September, amounting to 653 and the lowest was in January, 63 ships.

Judul: Utilization of VIIRS Boat Detection and Vessel  Monitoring System for Fisheries Surveillance in The Marine Sanctuary of  Southeast Aru Islands
Abstrak: Kawasan Konservasi Suaka Alam Perairan (SAP) Kepulauan Aru Bagian Tenggara berada di perairan WPPNRI-718, seluas 114.000 ha. Posisi Kabupaten Kepulauan Aru dikelilingi oleh Laut Aru dan Laut Arafura memiliki potensi sumberdaya hayati berlimpah. Tingginya tingkat penangkapan pada WPPNRI-718 membuat peluang bagi kapal penangkapan ikan masuk kedalam zona larang tangkap di kawasan konservasi. Penelitian ini bertujuan memetakan dan menghitung sebaran kapal berdasarkan data VIIRS Boat Detection (VBD) dengan data Vessel Monitoring System (VMS), membandingkan aktivitas pelanggaran antara kedua data dan merekomendasikan pengembangan pengawasan di kawasan konservasi. Penelitian ini menggunakan metode studi kasus berupa pelanggaran kapal penangkapan ikan di kawasan konservasi. Data yang digunakan adalah data VBD, VMS, batas kawasan konservasi dan kalender bulan. Hasil penelitian menunjukan bahwa berdasarkan data VMS, kapal yang terdeteksi berukuran 39- 198 Gross Tonnage (GT) menggunakan 11 jenis alat tangkap. Terdapat pelanggaran oleh kapal bouke ami, pancing cumi, purse seine dan jala jatuh berkapal dengan ukuran 58-148 GT. Pelanggaran banyak ditemukan pada bulan November saat musim penangkapan ikan di sekitar Pulau Enu dan Pulau Karang. Rekomendasi yang disarankan yaitu pengawasan lebih intensif dilakukan pada saat musim penangkapan ikan., The Southeast Aru Islands Marine Nature Reserve is located in WPPNRI- 718, with an area of 114.000 hectares. The position of Aru Islands Regency is surrounded by the Aru Sea and the Arafura Sea, which have enormous potential for biological resources. The Arafura Sea is an ocean where illegal fishing is common. The high rate of fishing in WPPNRI-718 creates opportunities for fishing vessels to enter the no-take zone in the conservation area. This study aims to calculate and map the distribution of fishing vessels based on data from VIIRS Boat Detection (VBD) with Vessel Monitoring System (VMS), compare violation activities between the two data, and recommend the development of surveillance in conservation areas. The distribution of fishing vessels in conservation zones is studied using a case study approach. The data used are VBD, VMS, conservation area boundaries and lunar calendars. The results showed that based on VMS data, the detected vessels were 39-198 Gross Tonnage (GT), which used 11 fishing gear. There are violations by bouke ami, squid jigging, purse seine and cast nets vessels with a size of 58-148 GT. Most of the violations were found in November during the fishing season around Enu Island and Karang Island. The recommended recommendation is that more intensive supervision is carried out during the fishing season.

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%.
