Abstract

Ekstrak kelopak bunga rosela banyak dimanfaatkan sebagai bahan baku pada produk pangan maupun non-pangan. Berdasarkan penelian sebelumnya menunjukkan bahwa penggunaan pektinase dan selulase dapat meningkatkan kadar antosianin yang diperoleh dari ekstrak. Pada penelitian ini, dilakukan optimasi kondisi ekstraksi kelopak bunga rosela (Hibiscus sabdariffa L.) menggunakan pektinase dan selulase dengan Response Surface Methodology (RSM) dengan perlakuan konsentrasi penambahan pektinase dan selulase 1:1 (500-1500 ppm), suhu ekstraksi (35-65 oC) dan waktu ekstraksi (30-90 menit). Pengaruh konsentrasi penambahan enzim, suhu dan waktu ekstraksi terhadap rendemen, kadar antosianin dan total padatan terlarut diuji dengan menggunakan central composite design, diperoleh nilai R2 pada ketiga respon sebesar 0,6. Berdasarkan hasil persamaan yang diperoleh pada setiap respon yang dianalisis, kondisi optimum diperoleh pada penambahan konsentrasi enzim 1000 ppm, suhu ekstraksi 50 oC dan waktu ekstraksi 10 menit . Pada keadaan ini diperoleh rendemen sebesar 84,20%, kadar  antosianin 479,70 mg/L dan total padatan terlarut 2,13 oBrix.

Abstract

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 farmers 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.

Abstract

Meat quality represents meat properties known by consumers and affects their acceptance.  Feed is one of the factors affecting meat quality.  Utilization of pineapple waste as a fiber source in cattle feeding is potential to reduce feed cost.  Pineapple waste can be used as feed and as meat tenderizer.  However, many believes that feeding pineapple waste to cattle distract beef quality.  This study was aimed at assessing meat sensory quality of Brahman Cross cattle fed pineapple waste as fiber source.  Six Brahman Cross (BX) cattle aged 2.5-3 years were used.  The cattle were fattened for 120 days.  Three cattle was fed rations containing concentrate and pineapple waste silage and the remaining cattle was fed rations containing concentrate and corn leaf silage. In the end of the study period, the animals were slaughtered and meat was cut based on the commercial slaughtering standard.  Meat samples of Longissimus dorsi muscles were taken.  Beef sample aging was conducted at 0ºC for 3 months.  Measurements of beef characteristics were taken monthly.  A completely randomized design was used.  Data were subjected to a Kruskal Wallis test and meat physical characteristics were analysed by repetaed measurement analysis of variance.  The parameters observed comprised pH values, tenderness, cooking loss, water holding capacity, meat colors (L*, a*, b* value), organoleptic test hedonic and hedonic quality (aroma, tenderness, color, and mucus).  The results showed that the pineapple waste did not have significant influences on meat physical characteristics observed, except meat color a* values at two month aging, meat color L* value at three month aging. It was concluded that pineapple was could be used as a fiber source in beef cattle fattening with no negative effect on meat quality.

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.

Abstract

Different thawing metods were applied to frozen beef in order for evaluating both the physical and chemical qualities.  The study used a completely randomized design with six treatments as follow:1) fresh beef  as  control, 2)  frozen  beef allowed  at  room temperature (27-300C)  until internaltemperature of beef reached 00C (became unfrozen), 3) Frozen beef thawed at refrigerator temperature, i.e. 8-100C, 4) Frozen beef thawed at running water which its temperature range within 25-280C, 5) Frozen beef thawed by boiling water (1000C), and 6) Frozen beef thawed by hot water (<1000C). Every treatment was made in three replicates. Results of the study repealed that frozen beef thawed by running water, hot water, or boiling water resulted in better physical qualities than the one thawed by refrigerator temperature (P<0.05). All thawing methods did not significantly affect on chemical qualities of the beef (P>0.05). Moreover, all frozen beef showed similar chemical qualities to the fresh beef.

Abstract

Turmeric is widely used as a herbal medicine, food preservation and food coloring. However, food industries have less interest to utilize turmeric as a food coloring due to its spesific aroma. The objective of this research was to obtain the proper method to eliminate the turmeric’s spesific aroma. The experimental methods consisted of 3 stages, namely distillation (A1) and non-distillation (A2) methods which then was extracted by maceration method with the addition of 96% ethanol (B1), acetone (B2) and ethanol 96% + acetone (B3) as stage 1; with (C1) and without heating (C2) as stage 2; and the addition of 3% acetic acid and 3% citric acid as stage 3. The results of stage 1, 2, and 3 were the spesific aroma of turmeric tend to be weak when use the distillation and maceration with 96% ethanol where the curcumin content was 0.50%, and with the addition of 3% acetic acid which have a brighter color, respectively. The color analysis showed that the color by adding 3% acetic acid has CIE b* (yellow) of 66.85 with pH of 3.24. So, the proper method for eliminating the turmeric’s spesific aroma was distillation process then followed by extraction using 96% ethanol and adding 3% acetic acid to increase the color brightness and homogeneity.
