Judul: Peran Subsektor Perikanan Tangkap terhadap Pembangunan Daerah serta Komoditas Hasil Tangkapan Unggulan di Kota Pekalongan.
Abstrak: Kota Pekalongan memiliki potensi sumberdaya perairan yang cukup besar. Besarnya rata-rata produksi perikanan per tahun sebesar 57.409.699 kg atau 27,45% dari rata-rata total produksi Provinsi Jawa Tengah sebesar 209.149.881 kg. Hal ini dapat dimanfaatkan secara maksimal guna meningkatkan kontribusinya terhadap PDRB. Oleh karena itu, perlu disusun suatu strategi pengembangan yang bertujuan meningkatkan peranan subsektor perikanan tangkap dalam pembangunan daerah. Hasil perhitungan LQ menunjukkan bahwa berdasarkan indikator PDRB dan tenaga kerja merupakan sektor basis dengan nilai LQ lebih dari 1. Berdasarkan hasil analisis efek pengganda selama periode 2003-2008, indikator PDRB dan indikator tenaga kerja, subsektor perikanan tangkap memberikan dampak positif terhadap pembangunan daerah Kota Pekalongan. Berdasarkan penentuan komoditas unggulan untuk subsektor perikanan tangkap, yaitu ikan manyung (Arius sp.) dari kelompok ikan demersal. Kelompok pelagis kecil terdiri atas selar (Caranx leptolepis), layang (Decapterus rocelli), tembang (Clupea fimbriata), lemuru (Clupea longiceps), kembung (Rastrelliger). Kelompok pelagis besar terdiri atas tongkol (Euthynnus spp) dan tenggiri (Scomberomerus commersoni). Kelompok binatang lunak adalah cumu-cumi (Loligo sp.). Hasil analisis SWOT menghasilkan tiga alternatif startegi pembangunan, yaitu 1) Memfokuskan pada peningkatan mutu hasil tangkapan dengan memaksimalkan kapal pengangkut ikan dan laboratorium pengujian mutu, guna menghasilkan kualitas produk ikan segar dan olahan yang memiliki nilai ekonomis tinggi serta memberikan kemudahan bagi masyarakat dalam akses sarana dan prasarana dalam mengembangkan usaha baru di bidang perikanan tangkap; 2) Melakukan pengembangan subsektor perikanan tangkap yang berkelanjutan dengan memanfaatkan kesempatan kerja yang besar dan hasil tangkapan unggulan guna memenuhi permintaan yang tinggi dari luar daerah, sehingga dapat meningkatkan kontribusi perikanan tangkap terhadap PDRB daerah; dan 3) Memberi kemudahan bagi nelayan dalam segala regulasi dan urusan administrasi sehingga nelayan dapat tetap konsisten dan dapat memanfaatkan potensi sumberdaya laut yang tersedia dan dapat memenuhi permintaan produk dari luar daerah.

Judul: Peran Subsektor Perikanan Tangkap terhadap Pembangunan Daerah serta Komoditas Hasil Tangkapan Unggulan di Kota Pekalongan
Abstrak: Pekalongan city has quite potential aquatic resources. Average annual production value was 57.409.699 kg or 27.45% of Central Java province total production which was 209.149.881 kg. This can be used maximally to improve the contribution to PDRB. Therefore it is necessary to formulate a development strategy aimed at enhancing the role of the capture fisheries sector in regional development. The results indicate that the LQ calculations based on the indicators of GDP and employment is a sector basis with LQ values greater than 1. Based on the analysis of the multiplier effect during the period 2003-2008, GDP indicator and the indicator of labor, capture fisheries sub-sector gave a positive impact on regional development of Pekalongan city. Based on the determination of superior fishery sub-sectors commodities, such as manyung (Arius sp.) from demersal fishes. Small pelagic group of selar (Caranx leptolepis), layang (Decapterus rocelli), tembang (Clupea fimbriata), lemuru (Clupea longiceps), kembung (Rastelliger). Large pelagic group of tongkol (Euthynnus spp) and tenggiri (Scomberomerus commersoni). Soft animal group are squids (Loligo sp.). SWOT analysis resulted three alternative development strategy, which are 1) Focusing on improving the captured quality by maximizing fish transport vessels and quality testing laboratory to produce high quality fresh and processed fish products, which have high economic value and provide convenience to the public on access to facilities and infrastructure in new business development in the field of fisheries; 2) Develop a sustainable fisheries sector through the use of the opportunities for employment and high quality of capture product to increase the contribution of capture fisheries toward regional PDRB; and 3) Provide convenience for fisherman in all regulations and documents, so that fishermen can remain consistent and able to use the potential of marine resources that are available and can meet the demand for products from outside the area.

Judul: Comparison of HIV Model with and without Time Delay
Abstrak: Acquired immunodeficiency syndrome (AIDS) is the reduction of the human immune system. AIDS is caused by human immunodeficiency virus (HIV). No medicine has been found for this desease until recently. An AIDS therapy is usually performed with highly active antiretroviral therapy, namely reverse transcriptase inhibitors, protease inhibitors and combination of both. Various models have been developed to explain the immune system of patients with AIDS, namely the HIV, response and the time delay model. This paper discusses the comparison between the dynamics of the HIV virus, the dynamic response of protease inhibitors and dynamics of time delay. The dynamics model of HIV is influenced by the level of white blood cells produced and the rate of its death. Dynamics of protease inhibitors on the response and the time delay model is influenced by the death rate of infected white blood cells and the failure rate of treatment.
