Judul: Kebijakan Pemerintah Daerah dan Peran Serta Masyarakat dalam Pembangunan Perikanan Tangkap di Daerah Purworejo
Abstrak: Pembagian urusan antara Pemerintah Pusat, Propinsi dan Pemerintah Daerah Kebupaten yang telah diatur dalam Peraturan Pemerintah No. 25 tahun 2000 memberikan wewenang kepada Pemerintah Daerah Kabupaten untuk menyusun kebijakan sesuai dengan potensi yang dimiliki daerah masing-masing. Berkaitan dengan kegiatan penangkapan yang baru dimulai pada tahun 2001, Pemerintah daerah Purworejo telah membuat beberapa kebijakan untuk mengembangkan kegiatan tersebut. Penelitian ini bertujuan untuk (1) mengidentifikasi dan mengetahui kebijakan perikanan tangkap daerah Pemerintah daerah Purworejo ditinjau dari wewenang yang didelegasikan oleh Pemerintah Pusat; (2) menetukan tingkat partisipasi masyarakat terhadap proses penyusunan, pelaksanaan dan evaluasi kebijakan; dan (3) merumuskan strategi untuk mengembangkan perikanan tangkap di daerah Purworejo. Penelitian ini dilakukan dengan metode studi pustaka dan metode survei. Perumusan alternatif strategi dianalisis menggunakan metode SWOT, dan penentuan prioritas strategi menggunakan matriks QSPM

Judul: Study of Chemoreaction Drying with Calcium Oxide and Its Impact on the Stress and Damage of Saccharomyces cerevisiae Culture, Kajian pengeringan kemoreaksi dengan kalsium oksida serta dampaknya terhadap stress dan kerusakan kultur Saccharomyces cerevisiae
Abstrak: The objective of the research was to study the parameters of the drying process and their effects on the viability of dried Saccharomyces cerevisiae culture. These parameters include the pattern of water isotherm sorption, the critical water contents, stress and mortality on a variety of bound water conditions, as well as morphological and micro-structural changes of damaged and leaked stressed cells. Layer thickness of the sample and high ratio used of calcium oxide speed up the drying process. Using a calcium oxide to sample ratio of 10:1 (w/w) for drying, 1.3 mm thickness of sample with 78-80% water content required 24 hours to dry to a final 4.42 % water content. The viability and cell content of the final product were 72% and 109 cells per g dried sample respectively. A sigmoid curve sorption isotherm pattern consist of 3 bound water regions of the dried yeast culture was similar to that of common dried foods. In the primary area most of the dried cells were dormant, in the secondary area the majority of the cells were under stress condition, while in the tertiary area a lot of them died. Likewise, the viability curve up to aw 0.2 was very low as due to high number of dormant cells, in between aw 0.2 - 0.6 sharply increased due to decreasing number of dormant cells, in between aw 0.6-0.75 sharply decreased due to increasing number of dying cells, and above 0.75 the cells was dying off to totally died. As shown by SEM observation, normal cells were oval-shaped with a smooth surface. In the primary region the dried cells showed and oval to round shape and small number of deformed cells, in the secondary region wrinkled surface and some number of deformed cells, while in the tertiary region the cells were sticky with wrinkled surface and most cells were damage. Meanwhile, TEM observation showed that the cells in the primary region had a well-defined, thick and solid cell wall with smooth surface with visible nuclei. In the secondary region the cells showed a wrinkled surface with less visible nuclei, while the wall was thin and cracked in some places. In the tertiary region the most number of cells were damaged, the remaining defined cells were flat, empty, irregular shape and no nuclei were visible. The increasing cell damaged was mainly due to the leaking out of cell or cytoplasm and the nuclear content through the damage cell wall. This was shown by increased electrical conductivity as well as the nucleic acid, nucleotide, protein and amino acids content of the cell-free supernatant from the culture. The Ca++ and K+ content of the cell mass decreased due to the leakage out of cell content. Sharp increase of K+ in secondary region of bound water was due to cell wall leakage, while high level of K+ in the tertiary region of bound water was due to high lysis of the cells with increased cell content damage.
