Judul: Pengembangan perikanan tangkap di Pangkalan Pendaratan Ikan ( (PPI) Paotere, Makassar
Abstrak: This research was conducted in fish landing bases (PPI) Paotere Makassar. The aim of this research was to identity the prime product of capture fisheries in order to develop capture fisheries production in Paotere, South Sulawesi and to inform the fishermen about the fishing units that feasible to be developed. Survey method was applied in this research, while purposive sampling method were used to collect data. Prime product in PPI Paotere were identity by scoring method. The result showed that prime product from fresh water commodities was milkfish (Chanos chanos) , while from sea water commodities was Indian scad or mackerel scad (Decapterus rusellii). Bio-technic-socio-economic-approach was applied to analysis the feasibility of capture fishery development in PPI Paotere. Based on study, it can be known that purse seine was the most feasible fishery to be developed, followed gillnet, line fishing and trap.

Judul: Strategy for Development of Superior Commodity  Based Capture Fisheries System at Logending Coastal Fishing Port Kebumen Central Java
Abstrak: Hasil tangkapan ikan di PPP Logending periode tahun 2016–2019 berfluktuasi, sementara itu nilai produksi cenderung naik. Hal ini disebabkan oleh beberapa faktor, seperti pendangkalan kolam pelabuhan dan faktor cuaca. Kondisi ini menjadi fokus kajian dengan menetapkan kebijakan yang tepat untuk pengembangannya berbasis komoditas ikan unggulan. Tujuan penelitian adalah menentukan sumber daya ikan komoditas unggulan, mendeskripsikan kondisi sistem perikanan tangkap, serta merumuskan prioritas kebijakan dalam strategi pengembangan perikanan tangkap komoditas unggulan yang berbasis di PPP Logending. Penelitian menggunakan pendekatan sistem. Pengambilan data lapang menggunakan metode survei. Analisis data meliputi aspek biologi, teknis, finansial, dan sosial, serta analisis hierarki proses. Hasil penelitian menunjukkan sumber daya ikan unggulan adalah ikan layur, bawal putih, dan tenggiri dengan nilai skor masing-masing (3,76; 2,25; dan 1,47). Musim penangkapan ikan terjadi pada bulan Agustus–November. Alat tangkap dominan gillnet dan trammel net dengan kapal berukuran 1–3 GT. Alternatif prioritas strategi pengembangan perikanan tangkap berbasis komoditas unggulan di PPP Logending adalah kualitas sumber daya manusia dengan nilai rasio kepentingan 0,620., The catch of fish at PPP Logending for the period 2016–2019 fluctuates, while the value of production tends to increase. This is due to several factors, such as siltation of the harbor pond and weather factors. This condition became the focus of the study by determining the right policy for its development based on superior fish commodities. The objectives of the study were to determine the fish resources of superior commodities, describe the condition of the capture fisheries system, and formulate policy priorities in the development strategy of superior commodity capture fisheries based at PPP Logending. The research used a system approach. Field data collection using survey method. Data analysis included biological, technical, financial, and social aspects, as well as hierarchical process analysis. The results showed that the leading fish resources were hairtail fish, white pomfret, and mackerel with respective score values (3.76; 2.25; and 1.47). The fishing season occurs in August–November. The dominant fishing gear is gillnet and trammel net with vessels of 1–3 GT. Alternative priority strategy for the development of capture fisheries based on superior commodities at PPP Logending is the quality of human resources with an importance ratio value of 0.620.

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.
