Judul: Karakteristik Alat Tangkap Purse Seine Waring di Pelabuhan Perikanan Pantai Dadap Kabupaten Indramayu, Jawa Barat.
Abstrak: Purse seine waring in Dadap is constructed by using mesh size 1,0 mm with the main catch of purse seine waring is anchovy (Stolephorus spp). During the day the total catch of purse seine waring is 223,8 kg, which is comprises of the main target anchovy 59,2 kg (25%), selaroides 34,5 kg (15%), mackerel fish 9,5 kg (4%), pony fish 3 kg (1%), pomfret fish 8,5 kg (4%), and others 36,1 kg (16%). During the night the total catch of purse seine waring is 528,8 kg, which is comprises of the main target anchovy 227 kg (43%), sardine 188 kg (36%), squid 28,1 kg (5%), scad 27,5 kg (5%), pony fish 12 kg (2%), and others 41,7 kg (8%). Total length of average the main target anchovy 6,75 ± 0.05 cm, selaroides 4,5 ± 0,24 cm, mackerel fish 26,5 ± 1,13 cm, pony fish 3,5 ± 0,19 cm, and sardine 7,5 ± 0,20 cm. The analysis single factor is Fhit > Ftab (α 0,05) is 10,93, there are significant differences of the result of purse seine waring in the day and at night.

Judul: Kajian Unit Penangkapan Purse Seine dan Kemungkinan Pengembangannya di Indramayu
Abstrak: Alat tangkap yang digunakan oleh nelayan di Kabupaten Indramayu adalah purse seine, gill net, lampara, jaring Mitik, pancing, sero, pukat pantai dan dogol. Diantara alat tangkap tersebut purse seine mempakan alat tangkap yang produktif dibandingkan alat tangkap lainnya yang terdapat di Kabupaten Indramayu dengan rata-rata perkembangan produksi sebesar 21,34% per tahun (DKP Indramayu, 2001). Ukuran unit penangkapan ini berukuran lebih besar dibandingkan unit penangkapan lainnya yang ada di Indramayu dan menyerap tenaga kerja yang besar pula sehingga diharapkan dapat mengurangi tingkat pengangguran di daerah tersebut. Berdasarkan keadaan tersebut, maka penulis tertarik untuk melakukan penelitian tentang kajian unit penangkapan purse seine dan kemungkinan pengembangannya di Kabupaten Indramayu.

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.
