"ABSTRAK
Penelitian ini bertujuan untuk mempelajari sifat edible film yang dibuat dari
tepung tapioka yang sudah dihidrolisis pada suhu 400C, pH sekitar 7,0 dan
pengaruh penambahan madu serta minyak goreng terhadap WVTR, dan
O2TR . Edible film dibuat dengan cara penambahan gliserol yang
berfungsi sebagai plasticizer. Variasi madu yang ditambahkan 0% hingga
25% dari berat tapioka dan variasi penambahan minyak goreng 0%
hingga 5% dari berat tapioka, kadar gliserol 20% dari berat tapioka. Edible
film dibuat dengan cara metode tuang menggunakan air dan alkohol 70%
sebagai pelarut dengan perbandingan 2:1 Pengujian yang dilakukan
adalah ketebalan film, kuat tarik, elongasi, WVTR (Water Vapour
Transmission Rate), O2TR (Oxygen Transmission Rate), dan foto SEM
(Scanning Electron Microscope). Hasil yang diperoleh menunjukkan
bahwa penambahan madu dapat menurunkan WVTR dan O2TR sebesar
31,19% dn 73,17%, sedangkan penambahan minyak goreng dapat
menurunkan WVTR dan O2TR sebesar 39,22% dan 60,97%. Hal ini
menunjukkan adanya efek sinergi antara gliserol dan madu, sedangkan
penambahan minyak goreng dapat membentuk lapisan di permukaan
seperti yang ditunjukkan oleh foto SEM, sehingga WVTR turun secara
signifikan."

"This research aims was to obtain the active edible coating of with the addition of red rice
extract as meatballs coating. This research was conducted in four steps: extraction of
antimicrobial compounds from red rice, preparation the red rice edible coating, formulation
meatballs and application the red rice edible coating, and analysis of physical properties and
organoleptic. The quality of meatballs was strongly influenced by the quality of materials that
has been used and the process of production. The addition of red rice extract as much as
0,125%, 0,25% and 0,5% compared with the control and analysis by the sensory test.
Statistically, the addition of red rice extract on making meatballs did not effect the level of
panelists from the aspect of shape, flavor, color and aroma of the meatballs (α = of 0,05%).
The use of red rice extracts in the production of edible film for coating the meatballs affect the
texture of the meatballs that has been stored for 0, 6, 12 and 18 hours. Most of the panelists
mentioned meatballs controls have somewhat glutinous, dry, elastic and compact. After 18
hours of storage meatball has a glutinous, wet, slimy, less elastic and less compact,
especially meatballs controls (38,5%).
Penelitian ini bertujuan untuk mengembangkan pelapis tipis aktif dapat di makan (active
edible coating) dari maltodekstrin dengan penambahan ekstrak angkak sebagai pelapis
bakso. Penelitian ini dilakukan dalam 4 tahap, yaitu ekstraksi senyawa antimikroba dari
angkak, pembuatan larutan active edible coating dengan penambahan ekstrak angkak,
pembuatan bakso dan pelapisannya dengan larutan active edible coating, dan analisis sifat
fisik, organoleptik produk bakso yang telah dilapis dengan active edible coating. Dari
penelitian ini diperoleh informasi tentang teknologi proses pembuatan active edible coating
dari maltodekstrin dengan penambahan senyawa antimikroba dari angkak, aktivitas
antimikroba dari larutan active edible coating yang dikembangkan, serta produk bakso yang
diberi active edible coating. Kualitas dari bakso daging sapi sangat dipengaruhi oleh kualitas
bahan baku dan bahan tambahan yang digunakan serta proses pembentukan adonan.
Penambahan ekstrak angkak sebanyak 0,125%, 0,25% dan 0,5% dibandingkan dengan
control tetap disukai oleh panelis. Secara +statistik, penambahan ekstrak angkak pada
pembuatan bakso tidak berpengaruh terhadap tingkat kesukaan panelis dari aspek bentuk,
rasa, warna, dan aroma dari bakso (α=0,05%). Penggunaan ekstrak angkak dalam
pembuatan edible film untuk pelapis bakso berpengaruh terhadap tekstur dari bakso selama
penyimpanan 0, 6, 12 dan 18 jam. Sebagian besar panelis menyebutkan bakso kontrol memiliki tekstur agak lengket-lengket, kering, kenyal dan kompak. Setelah penyimpanan 18
jam bakso memiliki tekstur lengket, basah, berlendir, kurang kenyal dan kurang kompak,
terutama bakso kontrol (38,5%)."

"Karwa A, Rai MK. 2010. Hitherto unreported Agaricus species of Central India. Nusantara Bioscience 2: 141-145. Melghat forest region from Central India was surveyed for occurrence of medicinal and culinary mushrooms during the years 2005-2008. Out of
total 153 species, ten species of Agaricus were recorded from different localities. Of these, seven species namely Agaricus bitorquis, A.
subrufescens, A. augustus, A. placomyces, A. essettei, A. basioanolosus and Agaricus sp. nov (a new species) are being reported for the
first time from the region. The commercial button mushroom Agaricus bisporus lacks good breeding characters due to its bisporic nature. These wild cousins of the button mushroom can definitely prove to be a good source of genetic manipulations to the existing strains and also to develop new strains with improved characters"

"One of the most important factors in the formulation of effective breeding plans for improving the genetic quality of crops and livestock is a knowledge of the relative contribution made by genes to the variability of a trait under consideration. The variability of phenotypic values for quantitative trait can be partitioned into genetic and non genetic (environment) components.
The heritability is defined as a ratio of additive genetic variances to phenotypic variances. The most important function of the heritability is its predictive role. Heritability value is an expression of the reliability of the phenotypic value as a guide to breeding values.
The edible portion trait of giant freshwater prawn has a high heritability, since most of the phenotypic variability is due to genetic variations. Thus, genetic improvement can be made by selecting individuals with preferred phenotype because the offspring-parent correlation should be high. This is called mass selection or individual selection, but it is actually based on the individual's own performance record or phenotype.
The giant freshwater prawn population from Cimanuk (Tanjung Air, West Jawa), Cimandiri (Pelabuhan Ratu, West Jawa) and Walanae (Maros, South Sulawesi), obtained from natural habitat, were used in this study. The determination of heritability were conducted on several charater i.e. carapace length, standard length, dressing perecentage, edible portion and weight. The determination of heritability was based on regression between parents and offsprings. Structure of selection was conducted by individual selection. Parental stocks were selected based on individual breeding value. Natural breeding were used for first and second progeny.
Larvae were reared of eggs originated from individual female that had been mated to double males. Female were reared in 200-litre concrete tanks and newly hatched larvae were placed in 50-litre conical tanks. Water was recirculated through the tanks. The duration of rearing the larvae was 35 days.
Fingerlings were reared in cages replaced on 500 m2 earthen pond. Grow-out of juveniles were reared on 100 m2 earthen ponds. Juveniles were fed pellets with 30 % protein content. The duration of grow-out was 3 months.
The results showed that the heritability values of carapace length, standard length, weight, dressing percentage, and edible portion trait were in the level of medium to high. These suggest that giant freshwater prawn populations from Cimanuk, Cimandiri and Walanae are responsive to selection. Indeed, individual selection on edible portion trait show a positive response to selection. Therefore, selection programme can be utilized for genetic improvement of giant freshwater prawn.

Heritabilitas merupakan rasio antara keragaman aditif dan keragaman fenotipe. Fungsi penting dari heritabilitas adalah bersifat prediktif pada generasi berikutnya. Nilainya dapat memperlihatkan nilai fenotipe yang pada akhirnya dapat digunakan sebagai breeding value . Nilai heritabilitas edible portion trait cukup tinggi pada udang galah. Oleh karena itu, program seleksi dapat diterapkan untuk meningkatkan mutu genetik udang galah.
Penelitian dilakukan dengan menggunakan populasi udang dari Cimanuk (Tanjung Air, Jawa Barat), Cimandiri (Pelabuhan Ratu, Jawa Barat), dan Walanae (Maros, Sulawesi selatan) yang di koleksi dari alam.
Penentuan heritabilitas dilaksanakan pada beberapa karakter yaitu panjang karapas, panjang standar, berat, dressing percentage, dan edible portion. Penetapan nilai heritabilitas didasarkan atas perbandingan antara induk dengan keturunannya. Struktur seleksi yang dilakukan adalah seleksi individu. Untuk memilih induk udang digunakan breeding value.
Untuk memproduksi keturunan F, dan F2 dilakukan pemijahan secara alami. Pemeliharaan larva udang dilakukan dengan menggunakan sistem air jernih. Untuk menghasilkan udang ukuran juvenil dan pembesaran udang, dilakukan di kolam tanah.
Hasil penelitian menunjukkan bahwa nilai heritabilitas pada karakter panjang karapas (0,68 - 0,86), panjang standar (0,43 - 0,90), berat tubuh (0,85?0,97), dressing percentage (0,49 - 0,95) dan edible portion trait (0,46- 0,67) memperlihatkan nilai medium sampai tinggi. Hasil yang diperoleh ini dapat di interpretasikan bahwa populasi udang dari Cimanuk, Cimandiri dan Walanae memperlihatkan indikasi respon yang positif, jika karakter-karakter tersebut akan di seleksi. Implementasi struktur seleksi individu pada edible portion trait populasi udang galah tersebut memberikan respon yang positif."

"Halitosis (bad breath) is the most complained problem among mouth and teeth health. The source of halitosis are volatile sulfur compounds produced by Streptococcus mutatn from degradation of food debris. Sirih leaves (Piper betle L.) are trditionally used as mouth antiseptic for its volatile oil. The aim of this research was to formulate sirih extract into an extract with minimum inhibitory concentration (MIC) with 96% ethanol for 24 hours, resulting to an extract with minimum inhibitory concentration (MIC), on Streptococcus mutans of 8.49 x 10 g/ml. The extract with streng quadrupele of the MIC, or equel to 0.92% provide iodine, was formulate using 2 factorial design. Corn starch, hydroxypropyl methycellulose (HPMC) and sorbitol were independent variables and drying time ,moisture, film hicknes, desintegrating time, and film streng were the dependent ones.The results showed that HPMC significantly fastened the drying time, decreased the moisture, and lengthened the desintegrating time. Sorbitol significantly fastened he drying time, increased the moisture, and strengthened the film, while corn stach decreased the moisture and lengthened the disintegrating time. Optimation of the formula ingredients using contour plot superimposed cannot be determinetd due to edible film disintegrating time that was out of comparative interval."
