Judul: Permintaan Kuantitas dan Kualitas Buah-buahan Rumahtangga di Provinsi Lampung
Abstrak: Lampung Province is one of the largest producers of fruits.That big production level is a matter of support in terms availability of fruits. If associated with consumption levels, can be known that these available fruits are not utilized optimally by consumers. It can be seen from the level consumption of fruits that still low. This study aim to: (1) analyze factors that affect the demand of fruits household at Lampung Province, (2) analyze the change response in quantity and quality demand of fruits due to changes in price and income at Lampung Province. Type of data used in this research is secondary data obtained from BPS (Central Bureau of Statistic), that is data from module consumption expenditure and kor household from SUSENAS result (Survei Sosial Ekonomi Nasional) for Lampung Province in 2013. This data was cross section with sampling household unit. The output data then analyze used AIDS (Almost Ideal Demand System) model, and single equation models with semilog form. The result shows that the variable price of fruits (either own price nor cross price), expenditure, and family size shown affect the demands of fruits. Based on value of the cross price elasticity, known that generally all fruits have a variation of demand elasticity, there are positive or negative in terms of both quality and quantity. Generally the value of income elasticity is positive on all types of fruits that analyzed. This means the increase in income will affected an increase in the demand for fruits both in terms of quantity and quality.

Judul: Analisis hubungan tingkat hasil dan tingkat ketersediaan tenaga dalam produksi tanaman pangan di Propinsi Lampung
Abstrak: Dalam kurun waktu 25 tahun (1969-1992) Indonesia telah berhasil membangun sektor pertaniannya secara mantap. Hal ini dibuktikan dengan pencapaian swasembada beras pada tahun 1984. Walaupun demikian, dalam PELITA V dan selanjutnya, usaha untuk mempertahankan swasembada beras masih merupakan masalah pokok dalam pembangunan pertanian di Indonesia di samping masalah meningkatkan produksi bahan pertanian lainnya. Usaha untuk mempertahankan swasembada beras dan peningkatan hasil pro- duksi tanaman pangan lainnya mendorong pemikiran ke arah pemanfaatan yang optimal setiap sumber daya pertanian yang tersedia. Tujuan penelitian ini adalah untuk menganalisis hubungan antara tingkat hasil Ton Setara Gabah Kering Giling (GKG) per hektar dan tingkat ketersediaan tenaga kw per hektar dalam memproduksi tanaman pangan di Propinsi Lampung. Secara spesifik tujuan penelitian ini adalah: Menghasilkan kurva dan persamaan matematika mengenai hubungan antara tingkat hasil Ton (SGKG): per hektar dengan tingkat ketersediaan tenaga (kw/hektar) dalam produksi tanaman pangan di Propinsi Lampung. Menghasilkan simulasi model untuk mengevaluasi dan memproyeksikan ketersediaan tenaga di Propinsi Lampung di masa yang akan datang serta menghasilkan kurva kecenderungan pergeseran distribusi sumber tenaga pertanian di Propinsi Lampung…dst

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.
