Judul: Utilization of VIIRS Boat Detection Data and Vessel Monitoring System Data for Surveillance Fishing Vessel Activities in Anambas Marine Protected Area
Abstrak: Aktivitas pelanggaran penangkapan ikan pada zona larang tangkap kawasan Taman Wisata Perairan (TWP) menyebabkan berbagai permasalahan yang harus ditangani oleh Loka Kawasan Konservasi Perairan Nasional Pekanbaru (LKKPN Pekanbaru) Kementerian Kelautan dan Perikanan Republik Indonesia. Penelitian ini bertujuan untuk mengidentifikasi kapal perikanan yang beroperasi di perairan Kabupaten Kepulauan Anambas, mendeteksi kemungkinan adanya aktivitas pelanggaran penangkapan ikan pada zona larang tangkap TWP Anambas, serta membandingkan pelanggaran penangkapan ikan yang terjadi pada zona larang tangkap TWP Anambas. Penelitian ini menggunakan data VIIRS Boat Detection (VBD) dan Vessel Monitoring System (VMS). Analisis data yang digunakan adalah analisis deskriptif, spasial overlay, dan analisis komparatif-deskriptif. Hasil penelitian menunjukkan bahwa aktivitas penangkapan ikan di TWP Anambas tidak hanya dilakukan oleh kapal yang berukuran 1-10 GT, namun terdapat aktivitas penangkapan yang dilakukan oleh kapal berukuran 30 GT atau lebih. Berdasarkan analisis spasial overlay, terdapat kesesuaian data antara data VBD dengan data VMS pada kawasan TWP Anambas. Beberapa rekomendasi tindakan dalam pengembangan pengawasan aktivitas kapal perikanan pada zona larang tangkap diantaranya adalah 1) penggunaan data satelit dan piranti penelusuran jejak sebagai early warning system dalam kegiatan pengawasan kapal perikanan; 2) mengembangkan algoritma yang dapat mengolah dan menganalisis langsung data mengenai sebaran dan posisi kapal pada kawasan konservasi perairan; 3) menandai/ marking transmitter kapal perikanan yang terdeteksi melakukan pelanggaran pada zona larang tangkap kawasan; 4) mengambil menyita SIPI (Surat izin penangkapan ikan) kapal perikanan yang terbukti melakukan pelanggaran, Fishing violation activities in the no-take zone of the Marine Protected Area (TWP) cause various problems that must be addressed by the Pekanbaru National Marine Conservation Area (LKKPN Pekanbaru) and the Ministry of Marine Affairs and Fisheries of the Republic of Indonesia. This research aims to identify fishing boats operating in the waters of the Anambas Islands Regency, detect possible fishing violations that occur in the no-take zone of TWP Anambas, compare fishing violations that occur in the no-take zone of TWP Anambas. This research uses VIIRS Boat Detection (VBD) and Vessel Monitoring System (VMS) data. The data analysis used was descriptive analysis, spatial overlay, and comparative analysis. The results showed that fishing activities in TWP Anambas were not only carried out by boats measuring 1-10 GT, but there were fishing activities carried out by vessels of 30 GT or more. Based on the spatialanalysis overlay, there is data compatibility between VBD data and VMS data in the TWP Anambas area. Several recommendations for actions in the development of monitoring of fishing vessel activities in the no-take zone include 1) using satellite data as an early warning system in fishing vessel surveillance activities; 2) developing algorithms that can process and analyze data directly on distribution patterns and ship positions in marine protected areas; 3) marking fishing boat transmitters detected in fishing violations in the no-take zone area; 4) take or confiscate a fishing boat SIPI (fishing permit) proven to have committed a violation

Judul: Pemanfaatan Citra Satelit SNPP/VIIRS/DNB dan Vessel Monitoring System untuk Pengawasan Kapal Perikanan di Taman Wisata Perairan Kepulauan Anambas
Abstrak: Terjadinya upaya penangkapan ikan pada zona larang tangkap, yaitu zona inti, zona pemanfaatan, dan zona lainnya menjadi permasalahan yang sedang terjadi di Taman Wisata Perairan (TWP) Kepulauan Anambas. Penelitian ini bertujuan untuk memetakan aktivitas kapal penangkapan ikan dari data VBD dan VMS selama satu tahun, membandingkan data VBD, data VMS dengan rekap data pelanggaran, dan memetakan daerah rawan pelanggaran di TWP Kepulauan Anambas. Penelitian ini memanfaatkan data VIIRS Boat Detection (VBD) dan Vessel Monitoring System (VMS). Analisis yang digunakan yaitu deskriptif, komparatif dan overlay. Hasil penelitian menunjukkan bahwa VBD merekam lebih banyak titik kapal dibandingkan VMS. Terdapat perbedaan antara data VBD dan VMS serta data pelanggaran dari tim pengawas TWP Kepulauan Anambas dengan gap data sekitar 72% dan matching data sekitar 19%. Daerah rawan pelanggaran merupakan zona larang tangkap, yaitu zona pemanfaatan, zona inti, dan zona lainnya yang tidak masuk kedalam wilayah pengawasan oleh pengelola TWP Kepulauan Anambas. Rekomendasi tindakan pengembangan pengawasan untuk pengelola TWP Kepulauan Anambas yaitu pemanfaatan data satelit VBD dan VMS sebagai sistem pendeteksi upaya penangkapan oleh kapal diatas 30 GT, memfokuskan beberapa kapal pengawas didaerah inti yang terindikasi rawan terhadap pelanggaran, mengembangkan sistem pantauan hingga mendapatkan informasi secara real-time aktivitas kapal perikanan, mengembangkan sistem alert warning. Kata Kunci: overlay, peta interaktif, Vessel Monitoring System, VIIRS Boat Detection, zona larang tangkap, The occurrence of fishing efforts in the fishing zone, namely the core zone, utilization zone, and other zones, is a problem in the Anambas Islands Water Tourism Park (TWP). The study aims to map fishing boat activity from VBD and VMS data for one year, compare VBD data, VMS data with breach data recaps, and map breach-prone areas in the Anambas Islands TWP. This study utilizes VIIRS Boat Detection (VBD) and Vessel Monitoring System (VMS) data. The analysis used is descriptive, comparative and overlay. The results showed that VBD recorded more ship points than VMS. There is a difference between VBD and VMS data and data breaches from the Anambas Islands TWP supervisory team with a data gap of about 72% and matching data of about 19%. Violation prone areas are no-take zones, namely utilization zones, core zones, and other zones not included in the surveillance area by the management of TWP Anambas Islands. Recommendations for surveillance development actions for the management of TWP Anambas Islands, namely the utilization of VBD and VMS satellite data as a detection system for capture efforts by ships over 30 GT, focusing several surveillance vessels in the core areas that are indicated to be prone to violations, developing monitoring systems to obtain information in real time fishing boat activity, developing an alert warning system.

Judul: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
