Judul: Daya dukung lahan untuk tenaga kerja pertanian dan pengembangan wilayah di Kabupaten Kudus
Abstrak: Declining of working interest in agricultural sector is affecting the land carrying capacity which is calculated based on the region's land availability compared with the region's population needs of land. The regional development with the establishment of infrastructure needs a proper land management to synergize the land utilization thus resulting in sustainable development. The research shows that in one year (2008) there are deficiencies in the needs of agricultural labor in two subdistrict: Kota subdistrict and Jekulo subdistrict in January to September. In Pebruary and October, Kaliwungu subdistrict, Kota subdistrict and Jekulo subdistrict and in December Kota Subdistrict are deficiencies in the needs of agricultural labor deficiencies in the needs of agricultural labor. Based on the land carrying capacity calculation, there is surplus in one subdistrict that is Dawe subistrict while the other eight subdistricts are deficits in their land carrying capacity. Agricultural labor availability do not give significantly different effect on land carrying capacity. Undaan, Mejobo, Jekulo, Gebog and Dawe subdistricts are agricultural basis region with the value of LQ> 1. Agricultural sector is significantly growing in Mejobo subdistrict. The Skalogram calculation resulting in Kota subdistrict is included in Hierarchy I, Bae and Jati subistricts are in Hierarchy II, while Dawe, Gebog, Jekulo, Kaliwungu, Mejobo and Undaan subdistricts are in Hierarchy III. The analysis result between the farm income and the factors affecting it shows that the pattern of irrigation, benefits, and cropping patterns are significantly affecting farm income. While the labor's origin between inside or outside the region has no significant effect. Variables of the agricultural labor availability, land carrying capacity and territory hierarchy do not give a significantly different effect on the subdistrict's agricultural sector GDP. Land carrying capacity must be considered in the regional development because it will determine the development sustainability.

Judul: Analisis lokasi dan dampak tenaga kerja industri di kabupaten Kudus
Abstrak: Pembangunan industri di suatu wilayah mempunyai peranan yang besar dalam pertumbuhan ekonomi regionalnya. Salah satu pendekatan untuk menjelaskan pertumbuhan daerah adalah dengan pendekatan basis ekonomi. Dalam model basis ekonomi, aktivitas perekonomian wilayah digolongkan menja- di dua yaitu aktivitas basis dan non basis. Peranan dan dampak pertumbuhan sektor ekonomi basis dapat menimbulkan dan menentukan pertumbuhan wilayah secara keseluruhan. Setiap pertumbuhan sektor basis dan non basis mempunyai efek pengganda (multiplier effect) terhadap perekonomian wilayah. Secara umum penelitian ini bertujuan untuk mengidentifikasi industri yang ada dan potensial untuk dikembangkan, orientasi lokasi serta dampaknya terhadap penyerapan tenaga kerja.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
