Silk can be produced by spider or insect and have prospect as biomaterial for regenerative healing in medical treatment. Silk having physical and chemical properties that support biocompatibility in the living things..In this research, silk that was obtained from Indonesia natural resource of Attacus atlas silkmoth was explored and then will be developed for biocompatible biomaterial. The treatment with NaOH was developed to separate the fiber from the cocoon. The obtained fiber is investigated its mechanical property by performing tensile test for single fiber. The biocompatibility testing was conducted with human cell (osteosarccoma) cultivation. The result identify that separation by using NaOH yield better better mechanical properties comparing konvenstional method with boiling in hot water. Biocompatibility testing indicate that the the fiber having good biocompatibility.

A study aimed at studying the performance and production of Balinese duck carcasses that were given rations containing biosupplement-based waste of rumen content, conducted in the village of Peguyangan, Denpasar, Bali, for 3 months. Four biosupplements produced in this study were 1) BR0 = biosupplement with fermented rumen based waste without bacterial isolates, 2) BR1 = biosupplement with fermented rumen based waste with superior 1 cellulolytic bacteria inoculant (BR3.5), 3) BR2 = biosupplement with fermented rumen based waste with superior 2 cellulolytic bacterial inoculants (BR3.3), 4) BRmix = biosupplement with fermented rumen based waste with combination of superior cellulolytic bacteria 1 and 2 (BR3.5 and BR3.3), The study was carried out with Completely Randomized Sampling/CR Design with 5 treatments and 3 repetitions, in which each repetition consisted of 5 Balinese ducklings aged 2 weeks. The treatment given was to ducks given supplemented ration with BR0; BR1; BR2; BRmix, respectively for the treatment of R1; R2; R3; and R4, as well as ducks that were given basal rations without supplementation (R5). The results showed that the performance of duck that received treatment of R2 was significantly better (P<0,05) than R1, R3, R4 and R5, while the carcass butching weight and fat weight were not significantly different (P>0,05) . Based on the results obtained, it can be concluded; 1) the performance of Balinese ducks receiving ration biosupplement of R2 is better compared to R1, R3, R4 and R5; 2) Meat production/ducks carcasses to the weight of butchery, carcass production, non-carcass parts and body fats are not significantly real between all treatments.

Trigona is a stingless bee that protects itself by swarming and biting. The bee products that are widely used in addition to honey are propolis, wax and the royal jelly. Trigona bee is one of potentially honey producer that has not been widely known. One species of trigona bee found in Bali is the Trigona laeviceps. They are nested in the crevices of rocks or in the tree trunk. This research aims to determine variations of entrance shapes, food storage, and brood cells of T. laeviceps from different altitudes. Colonies were observed in the Laboratory of Animal Taxonomy, Biology Department, Faculty of Mathematics and Basic Sciences, Udayana University, and nest entrance was analyzed in the Analytic Laboratory, Udayana University. Colonies were collected from bamboo nest in a tubular form and wooden nest from wooden boxes. Nest entrance is either flat or protruded out of the nest in an oval shape. The form of the entrance is not affected by the altitude. The nest entrance contained around 0,05 % flavonoids. The size and shape of pollen and honey pots volume was lightly lager in colonies collected from altitudes more than 400m above sea level (0.058 ± 0.04 mm³) than colonies collected from altitudes less than 400 m above sea level (0.035 ± 0.03 mm³). Royal jelly pots and brood cells have also similar shapes, but the volume is larger in colonies collected from altitudes less than 400 m above sea level (0.015 ± 0.07mm³) compared to altitude of more than 400 m above sea level (0.011 ± 0.02 mm³ )

Determination of Flavonoid, Tannin and Vitamin C Content from Methanol Extract Wrapping Stone Banana (Musa brachycarpa), Ketip Banana (Musa Paradisiaca Forma Typiaca) and Kepok Banana (Musa acuminata) Ni Putu Adriani Astiti; Dwi Ariani Yulihastuti

Research has been done to investigate the levels of flavanoid, tannin, and vitamin C of methanol extract of Stone banana (Musa brachycarpa), Ketip banana (Musa paradisiaca forma typiaca ), and Kepok banana (Musa acuminata). Jukut Ares is a Balinese traditional cuisine frequently served in any events of celebrations. The use of young stems of such banana varieties as the main raw materials in the process of making jukut ares has not been scientifically elucidated. Antioxidants are compounds with ability to inhibit oxidation-related reactions due to free radicals that cause disturbance of saturated fatty acids of cell membrane, blood vessels, DNA, as well as adipose tissues which lead to occurrence of various diseases. Plants components will have antioxidant activities if they contain compounds (phenol and flavanoid) with ability to scavenge free radicals. Tannin is a water based phenolic compound and vitamin C is also a water based vitamin that play important roles in preventing us from various diseases. Extraction was conducted by applying maceration method and to investigate the levels of flavanoid, spectrophotometric UV vis with aluminum chloride (AlCl3) was applied. The level of vitamin C of the materials was conducted by Iodine titration method, while the level of tannin was determind by applying spectrophotometri. The results showed that methanol extract of Ketip banana stem contained the highest level of flavanoid with a quantity of 53.13 mg/100gr QE, and this was followed by stone banana (36.28) and kepok banana (32.07) The highest vitamin C level was indicated in the extract of ketip banana (418.32 mg/100gr), which is followed by kapok banana and stone banana. In the calculation of tannin content, pisang ketip showed the highest level, while pisang batu contained the lowest level of tannin.

This research aims to determine the financial feasibility on the farming business of breeding balinese cattle who uses KUPS Credit Scheme. Data was collected through observation and interview. Respondents were all members of the “Satwa Winangun” farmers in Tangkas village, Klungkung Regency. Financial feasibility is determined by evaluating the eligibility criteria such: NPV, Net B/C, IRR, and payback period. The assessment was based on 2 calculation systems, (1) calculation of cash costs in which forage and labor are not calculated as the cost (existing condition), and (2) total cost calculation, in which two components are calculated as cost. Based on the calculation of cash costs, cultivation of Bali cattle by utilizing KUPS credit in this village is financially feasible to be implemented. This was indicated by the NPV value of Rp. 274.103.000, IRR 20.16%, Net B/C 1.55, and investments has been able to return within 3.52 years. The result of sensitivity analysis shows that as far as KUPS interest rate is lower than 18.37% per year, this farming is still financially feasible. Breakeven point can be achieved when the number of cattle parents maintained is 37, or when the price of calves at the age of 6 months is an average of Rp. 1.764.022 per cattle. However, based on the calculation of total cost, this farming system is not financially feasible. This is shown by the negative NPV of Rp. -285.721.000, IRR 2.87%, and Net B/C 0,54. This farming system is not financially feasible despite the 0% / year KUPS rate. The break-even point can be reached when the price of calves at the age of 6 months averages Rp. 4.288.367 per cattle.

Minerals play an important role in activating the lymphoid cells. Mineral deficiency can cause interference prolifrasi in lymphocytes, particularly the expresion of CD4+. Bali cattle are hardly given additional mineral due to cattles are in semi-intensive breeding method. Therefore, this study aims to determine the expression of CD4+ lymphocytes Bali cattle after consuming of mixed mineral. The samples used were 32 male bali cattles reared in the village of Catur, Kintamani, Bangli regency. Samples were divided into 2 groups, those were: 16 individul of bali cattle was given 7.5gr additional of mixed mineral per individual/day, and theother 16 individual as acontrol. The treatmnes were conducted for 3 months. The results showed that administration of 7.5gr mixed mineral per individual/day did not show differences in the expression of CD4+ lymphocyte of bali cattle.
