Judul: Karakteristik Payang Gemplo (Seine Net) di Pelabuhan Perikanan Pantai Dadap, Kabupaten Indramayu.
Abstrak: Payang gemplo consists of three parts, such as wings, body and bag. Mesh size in the bag is 0,1cm and 0,4 cm, body is 10,5-35 cm and wing is 40 cm. The main catch is an anchovy (Stolephorus sp.) and small pelagic fish. Catching method of payang uses one boat system and fishing operations carried out during the day (one day fishing) with a boat size of 3 to 5 GT. The composition of the catch comprises of anchovy (Stolephorus sp.) as a target catch with 43,73%. While the bycatch consists of other fish 22,74%, such as pony fish (Leiognathus dussumieri) 11,37%, long jawed mackerel (Rastrelliger sp.) 10,2%, sardine (Sardinella gibbosa) 4,90%, hair tail (Trichiurus savala) 2,90%, and pomfret fish (Pampus argentus) and mackerel (Selaroides sp.) each for 2,07%. Based on the analysis of the Shannon-Wiener diversity index indicated value of the index at 1,24 or > 0,1 which means payang gemplo fishing gear in Dadap is categorized low selectivity.

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.
