Judul: Aplikasi Data Visible Infrared Imaging Radio Suite (VIIRS) untuk Pemantauan Aktivitas Kapal di Kawasan Konservasi Raja Ampat
Abstrak: Kawasan konservasi perairan adalah kawasan perairan yang dilindungi dan dikelola dengan sistem zonasi untuk mewujudkan pengelolaan sumberdaya perairan yang berkelanjutan. Pengawasan dengan sensor Visible Infrared Imaging Radio Suite (VIIRS) menjadi inovasi dalam pengawasan di malam hari sebagai instrumen pendukung Vessel Monitoring System (VMS). Analisis data VIIRS dilakukan dengan metode query untuk mendapatkan Qualities Flag 1 (QF1) atau deteksi kuat, kemudian dilakukan overlay analysis untuk mendapatkan jumlah deteksi pada setiap zonasi Kawasan Konservasi Perairan Raja Ampat. Metode purpoisive random sampling kapal digunakan dalam survei lapang. Data akumulasi aktivitas harian yang dapat di deteksi ketika malam hari pada tahun 2013, 2014, 2015, dan 2016 berturut-turut mencapai 143, 221, 288 , dan 296 deteksi. Aktivitas pada zona inti terdeteksi pada bulan April (2013); bulan April, Juli, dan September (2014); serta bulan April dan Juli (2015). Hasil deteksi sensor VIIRS menunjukkan aktivitas malam hari dominan terjadi di Kawasan Konservasi Perairan Daerah Misool Timur Selatan sehingga sensor VIIRS terbukti dapat membantu VMS dalam pengawasan kawasan konservasi.

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: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
