Abstract

Preparation of cellulose film from nata de pina, a product of pinapple fermentation, using acetobacter xylinum was done at room temperature for 15 days. The aim of the research is to investigate the effect of sugar concentration and pH on film quality. The fermentation run at sugar concentration of 0, 5, 7.5, 10 and 12.5% and at pH of 3, 5 and 7. Results show that the best nata de pina was obtained at sugar concentration of 10% and pH 5. At these conditions, maximum nata precipitates rendemen was 26,80%, with a moisture content of 80,55%, and the thickness of 3,30 cm. The product nata then can be used to produce cellulose film. The characteristic of the produced film were 8,20 Kgf/mm2 and 11,71% for maximum tensile strength and elongation, respectively.Keywords: acetobacter xylinum, film, nata de pina, selulosa

This research aimed at analysing how copyrights could bring about economic rights for innovators and authors. In addition of generating economic rights, copyrights also protecting intellectual property rights. As we know, intellectual property rights is rights obtained from one’s thoughts or ideas, and it has economical values for the innovator and/or author. As it consequence, people required to get license from and grant royalty to the innovator and/or author when they need to gain further these economic values. This condition also valid to the copyrights as contained in law no. 28 of 2014 on Copyrights. Research here focused on economic rights of copyrights; what kind of economic advantages would gained by the innovator and/or author of his/her creation Keywords: Copyrights, Economic Rights, Intellectual Property Rights

Abstract

The objective of the current study was to asses the optimal concentration of glutamine, glycine and cysteine amino acids in tris-citric-acid-fructose egg yolks (TCFY) extender on quality of SO bull spermatozoa during freezing and thawing. In this study the DNA stability of frozen-thawed Sperm was also indentified. Three mature bulls maintained at PT. Karya Anugerah Rumpin, private cattle breeding company, West Java, Indonesia were used as semen donors. Semen was collected using artificial vagina and were evaluated prior to freezing. Semen was diluted with TCFY supplemented with different concentrations of amino acids (5, 15 and 25 mM glycine and glutamine, and 3, 5 and 7 mM cysteine) then processed for colling and freezing. Semen quality parameters (subjective motility, viability and membrane and DNA integrity). Data showed that in general the effect of addition of selected amino acids (glycine, glutamine and cysteine) into TCFY extenders on motility, viability and membrane integrity of SO spermatozoa after cooling were significantly different (p<0.05) higher than that of control. Addition of 15 mM glycine, 15 mM glutamine and 5 mM cysteine resulted in significant (p<0.05) increase post-thawing sperm motility and sperm viability as compared to that of control. Furthermore, when spermatozoa were stained with acridine orange after fixation with acetic alcohol, the DNA integrity of post-thawing spermatozoa showed that all spermatozoa were remain intact. In conclusion ,addition of 15 mM glycine, glutamine and 5 mM cysteine increase the cryoprotecting efficacy of bovine bull cryopreservation extender, and furthermore all DNA spermatozoa were remain intact.

Abstract

Sebagian besar negara di dunia memilih bentuk negara Federal atau Kesatuan dalam menyelenggarakan pemerintahan. Pemilihan bentuk negara ini didasarkan kemauan politik, sosial budaya serta sejarah dari sebuah negara. Masing-masing bentuk negara ini mempunyai kelebihan dan kelemahan. Negara Kesatuan menitikberatkan penyelenggaraan pemerintahan pada pemerintahan pusat dan daerah-daerah di propinsi tidak mempunyai otonomi yang luas dalam mengurus daerahnya. Lain halnya dengan Negara Federal dimana kedudukan Negara Federal dan Negara Bagian sederajat. Negara Bagian diberikan otonomi yang seluas-luasnya untuk mengurus daerah mereka. Sehingga hal ini sangat menarik bagi penulis untuk mengkaji lebih dalam, bentuk negara yang bagaimana yang bisa menjamin terlaksananya otonomi daerah dilihat dalam konteks sejarah perjalanan Bangsa Indonesia.
