This objective of tis research was to: 1) Determine whether the Central Lampung District has a comparative advantage and competitive advantage in rice production. 2) Determine how the sensitivity of changes in output prices and input prices to the comparative and competitive advantage in rice production. Location of the study was conducted at the Rama Utama Village and Ramayana Village, Seputih Raman Subdistrict of Central Lampung District. This research was conducted by survey and interview methods to farmers by using a questionnaire that had been prepared. Respondents in this research is rice farmer in the Seputih Raman subdistrict of Central Lampung District, totally 73 farmers were selected by simple random sampling method (simple random sampling). Types of data used are primary and secondary data obtained through direct interviews and offices or agencies. To answer the first objective analysis was used Policy Analysis Matrix (PAM) and to answer the second objective was used sensitivity analysis. Results showed that: 1) rice farming in Central Lampung District has a comparative advantage and competitive advantage with a value of PCR (Private Cost Ratio) equal to 0.4635 and the value of the DRC (Domestic Resource Cost) of 0.4368 so that feasible and profitable to be conducted. 2) comparative and competitive advantage of rice production in Central Lampung District is sensitive to changes in output prices. Increase or decrease of output prices will affect the comparative and competitive advantage of of rice production in Central Lampung District. Keywords: Comparative Advantage, Competitive, Paddy Production

The objective of this research was to known of acid and alkali effect to produced chitosan from rajungan husk. The implemented treatments were including deproteinization, demineralization and deasetylation treatments with several of acid and alkali. The deproteinization were conducted by 3-5 % NaOH and warm to 80o C than 2% HCl or H3PO4. Finally, chitosan produced by deasetylation with 30-40% NaOH. 100 gram substrates were produced 19% rendemen with deasetylation degree (DD) is 29,02%. Test of the chitosan at bakso and fish showed good condition until 48-50 hours. That is influenced by water activity of the materials. Keywords : rajungan husk, deproteinization, demineralization, deasetylation, chitosan

The objective of the research was to know comparation of two strains of broiler performance when water kunyit of consumption. Level of water kunyit as treatmentwas 10 g/600 ml. Two strains of broiler were CP 707 unsexed and Lohmann unsexed. Every broiler strain consist of 100 Day Old Chicken (DOC). Experiment was designed with two treatments of strain broiler and each treatment had 15 replications. Each replication was 6 or 7 DOC. Comparison of data was analyzed by using t-student on signification 5% (Steel dan Torrie, 1993). Parameters measured were water consumption, feed intake, body weight gain, feed conversion, and income over feed cost. Results showed the highest effect of kunyit water significant (P<0,05) of broiler performance of strain CP 707 on water consumption, feed intake, and body weight gain, but no significant effect on feed conversion, and income over feed cost. Broiler of strain CP 707 was the responsive to treated water kunyit of consumption which shown on its effect on performance.Keywords: water kunyit, performance, strain, broiler

Propagation of cassava through in vitro culture is needed by farmers and agro industries to fulfill the need of the best and the newest clone as soon as after that clone is released by government. The objective of this research is to know the effect of the application of some concentration sucrose and activated charcoal on in vitro and ex vitro growth of micro-cutting of cassava. Explants used were one-node cuttings of cassava, which were derived from sterile shoot culture. The explants were cultured on MS basal medium supplemented with 0,2 mg.l-1 benzyl adenine. This research was arranged in completely randomized design with the treatments consisting of some concentrations of sucrose: 3%, 4% and 5% and concentration of activated charcoal: 0% and 0,1%. Each treatment was replicated 7 times with 4 explants in each experiment unit. The best growth micro-cutting of cassava in vitrowas achieved by treatment of 3% sucrose without activated charcoal. Keywords: Micro-cutting, Cassava

The objective of this study to analyze the dominant factors that potentially could affect the food security of households in the village of Trimomukti, Candipuro District and the village of Kelawi, Bakauheni District, South Lampung Regency; look for the dominant factors that potentially could affect the nutritional status of children and how the relationship between household food security levels with nutritional status of children in the region. Results showed the average household energy adequacy in both villages is still highly dependent on food energy contribution of cereals, especially rice. Based on logistic regression model, Greater the number of members in a household with low income and food expenditure against revenue high, and obtained a principal food source rice from membeli or aid and subsidies as well as from the community Kelawi Village will have greater opportunities for prisoners vulnerable to lack of food.Based on ordinal logistic regression model, increasing age of a toddler with food consumption of energy sources that do not meet the need and the ratio of food expenditure of households on incomes greater, the chances these children will experience moderate malnutrition will be higher and even worse. Seen the relationship between household food security with nutrition status, if a food is resistant to household, the nutritional status of children under five will get better. Regional differences in factors that contribute to the adequacy of the village of rice per capita did not have a significant influence on household level food security and nutritional status of children.

The prominent purpose this experiment was producing superior quality of Carasius auratus, which is have to growth faster and good morphology. While particular purpose was to know temperature level effect on triploidisation on individual triploid (3n) formation of Carasius auratus and to find suitable spawning method /combination in Carasius auratus propagation but settle make high productivity. Spawning was conducted using induce breeding. Carasius auratus was spawn with support by hormone stimulation. Triploidisation was using heat shock to achieve triploid fish (3n). The same procedure was conducted to control. Heat shock temperature level was 40, 41 and 42oC. Result of this experiment showed that fish on heat shock 40oC given individual triploid presentation high more than fish on heat shock 41 and 42o C. Where as control was 100% of individual diploid. Hatching and larvae survival rate were shown value lower than control without heat shock. Keywords: Carasius auratus, quality, triploidisation

The research was conducted in research station Polytechnic of Lampung, started the April from November 2009. The experiment was conducted in randomized completely block design with 3 replications. The treatments irrigation interval water gift time consist of 4, 6, 8, and 10 days. The parameters that were (1) tall plants, (2) fruit total formed, (3) production, (4) irrigation water gift total, and (5) water productivity. The data obtained to be analysed use anova, with BNT test for the mean of treatments value with level 0.05. The result of research indicate that are irrigation interval of 8 days in tomato plants cultivar Mutiara at dry season of lowland gave economical benefit per unit of water and can be conserved 47% irrigation water with production 1.28 kg.plants-1 (28.33 ton.ha-1). Keywords : Irrigation interval, tomato production, dry season, lowland
