The research is aimed to know and analyze the blood picture of hard-lipped barb that infected by Aeromonas hydrophila. The experimental research used complete randomized design with 7 treatments and each 2 replications. The treatments are Control (without A. hydrophila injection), A (with 104 cfu/mL injection), B (with 105 cfu/mL injection), C (with 106 cfu/mL injection), D (with 107 cfu/mL injection), E (with 108 cfu/mL injection), and F (with 109 cfu/mL injection). The other than Control treatment, each fish in the experimental research was injected via intramuscular with a virulen strain Aeromonas hydrophila bacteria according to the dose of treatment as much as 0.1 mL. The results of research showed that total erythrocytes 1,01 x 106 sel/mm3-1,31 x 106 sel/mm3 and the hemoglobin 2,3 g%-5,2 g% levels have experienced decrease, while total leucocytes 4,32 x 104 sel/mm3-7,53 x 104 sel/mm3 have experienced increase and hematocrite 19,2%-21,4% levels were stable.

Cooking oil was one of the basic needs which consumed by the whole of Indonesian society. The high price of palm cooking oil and the lack of knowledge caused the repeated using of palm cooking oil which is harmful to health. The objective was to determine the physicochemical changes of used palm oil (Jelantah) on chicken frying. This research was using purposive sampling method. The experimental design used completely randomized design with one factor of frying frequency which were 0, 3, 7 and 10 times. Statistical analysis showed that the physicochemical tests (color analysis, peroxide value, acid value and moisture content) in each test was significant or significantly different, from the linear regression predicted that the frying frequencies which were used in fried chicken vendors were 16-54 times. In addition, it can be seen the characteristic qualities of used palm oil on chicken frying namely: color analysis L from 39.40% to 46.49%, a from 5.80% to 9.26%, b from 16,57% to 22.82%; peroxide value from 1.599 meq/kg to5.623 meq/kg; acid value from 0.076% to 0.153%; and water content from 0.021% to 0.267%. The physicochemical tests of used palm oil sample from fried chicken vendors namely: color analysis at L of 27.11%, a of 9.63%, b of 18.02%; peroxide value of 10.07 meq / Kg; acid value 0.434%; and water content of 0.166%.

Roselle petals can be made into extracts as a source of raw material for food products and other products. Previous research states that the use of pectinase and cellulase enzymes can increase the yield including the anthocyanin content. This study aims to optimize the extraction conditions of roselle flower petals (Hibiscus sabdariffa L.) using pectinase and cellulase enzymes by using Response Surface Methodology (RSM). The treatment conditions were using pectinase and cellulase enzyme (1: 1) with concentrations in the range between 500-1500 ppm, extraction temperature between 35-65 oC and extraction time between 30-90 minutes. Analysis of the best treatment was carried out on the yield level, anthocyanin content and total dissolved solids tested using central composite design, obtained R2 values for the three responses of 0.6. The results showed that based on the surface response, the optimum conditions of the best extraction of the rosella at the addition of enzyme concentration of 1000 ppm, extraction temperature of 50 oC and extraction time of 10 minutes. In this condition, the yield of dried extracts of rosella was 84,20%, anthocyanins content 479,70 mg/L and total soluble solid 2,13 oBrix.

Taro is rich in nutrients and purple sweet potato is rich in anthocyanin which can be functioned as a pigment. The aims of the study were to determine the best paste formulated using taro flour and mash sweet potato based on sensory quality test, to evaluate the preference level of crackers using hedonic test and to analyze the chemical properties of selected product. The study was begun with pasta preparation assigned by three ratios of taro flour and mash purple sweet potato (1:1 , 3:1 and 1:3). The sensory qualities of paste including color, taste, and texture were analyzed. Paste made with ratio of taro flour and mash purple sweet potato 1:3 had the best sensory qualities. The paste was then used for crackers making, crackers with filler of paste (sandwich) and crackers made by mixing the dough and paste. Each crackers was then evaluated its preference level using hedonic test including color, aroma, taste, crispyness, and the preferred crackers was analyzed its chemical properties including moisture, ash, protein, lipid, and carbohydrate. The results showed that sandwich crackers was preferred than mixed dough-paste crackers and contained of moisture 3.54%, ash 0.82%, protein 8.57%, fat 7.15%, and carbohydrates 79.93%.

Research on Influence of Egg Shape and Egg Weight on Characteristic of Quilted Egg (Coturnix coturnix japonica) has been done for one month, this research aim to know the influence of egg shape and egg weight to fertility, hatchability, hatching weight, and sex in bird Quail and can select good egg weight to hatch. This study used quail eggs (Coturnix coturnix japonica), as many as 216 grains divided into two groups. Each is a group with an egg shape (pointed, semi-pointed, and round) and group with egg weight (mild, moderate, and severe). The hatching machine used is semi-automatic hatching machine, before the egg is inserted into the hatching machine is done selection that includes egg shape and egg weight, egg shape selection is done by measuring the width and length of eggs using sliding and egg weight is done by weighing the eggs with scales digital. The first factor is egg form with three levels, A1 (egg taper = 75 - 78,12%), A2 (semi-pointed egg = 79,59 - 82,11%), and A3 (round = 82,78 - 86,76 %). While the second factor is the egg weight of three levels namely B1 (light weight = 9 - 10 grams), B2 (Medium weight = 11-12 grams) and B3 (Weight = 13-14 grams). Of the 2 factors with three levels were obtained 9 treatment combinations of each treatment repeated 4 times, each repetition consisted of 6 grains. The experimental design used was Completely Randomized Design (RAL) 3 x 3 factorial pattern for fertility variables, hatchability, hatching weight and percentage of male sex. The results showed that the eggs did not give a significant effect on fertility, hatchability, hatching and sex weights, whereas for egg weight only had a significant effect on hatch and percentage of male sex.

The price gap between farmers and retailers in commercial vegetables like spinach, tomatoes, potatoes and shallots in Bogor City was predicted as a result from the high trading margin. The research aims to analyze income, margin and farmer share obtained by commercial vegetable supply chain actors in Bogor City. The study was conducted in March - October 2017 at the Bogor Traditional Market and the Jambu Traditional Market. The selection of respondents used the purposive sampling and snowball sampling method. Result shows that the R / C ratio of farmers is lower than that of traders. The R/C ratio received by farmers is 1,48, while that received by traders is 2,64. The average Farmer Share (41,2%) is lower than the seller share (58,8%). The average marketing margin is Rp 14,576.5. The supply chain that take side to farmers regarding to the value of R/C, the total margin and the farmer's share value are found in potato commodities because it has a higher R / C ratio than traders, higher farmer shares than traders, and trading margin that lower than the three other commodities compared
