Tilapia (Oreochromis niloticus) is one of the main commodities of freshwater fish in Indonesia. Mostly, tilapia is exported in the form of fillets which produce residual processing including bobe, skin, and scales which can reach 50 to 70% of the total weight of fish. The aimed of this study was to extract and characterize collagen from bone, skin, and scales of tilapia. The research method used a Completely Randomized Design (CRD) by treating the different types of collagen raw materials, namely bone, skin, and scales of tilapia. The results showed that the type of raw material affected the yield, water content, color, and pH (p<0.05). The collagen yield in this study was 0.53% (bone), 0.63% (scales) and 0.94% (skin). The small amount of amendment was caused by the concentration of acetic acid being too low. the smallest water content in tilapia fish collagen 2.17%; the best brightness of collagen in fish bones 76.91%; the value of the largest degree of white on fish scales 75.95%; pH content close to neutral fish collagen scales 6.49; Morphological results of collagen produced using SEM, the presence of pores seen in the collagen of tilapia fish due to the space between the collagen fibers while.

Reproductive traits determine the selection method in plant breeding. The benggala grass of the Hamil cultivar was thought to be apomictic; thus, a study was conducted to determine its reproduction. The research began by studying the morphological characters, continued with observing the generative phase and seed production of the cultivar planted from seeds (generative) and from pols (vegetative). The experiment was conducted in the greenhouse of the Research Institute of Animal Production. The experimental design was a completely randomized design with ten replications, and the treatments were different types of plant materials: seeds and pols. The Hamil cultivar taken from RIAP Collection was planted in pots with a diameter of 40 cm and a height of 30 cm. The results showed that most of the morphological characters of the Hamil cultivar planted from seeds and from pols were not different (P >0.05), so it was presumed that they were apomictic. The difference in morphology was only in the length and width of the flag leaves and the length of the internodes, where the cultivars planted using seeds were higher. The production of seeds, pithy seed weight, and seed germination of cultivars planted using seeds were higher (P <0.05). Further research is needed to determine the apomixis properties based on cytologically Hamil cultivars.   Keywords: apomixis, benggala grass, morphology, plnting material; seed

Corn (Zea mays) is one of the most cultivated poaceae in the world with high agricultural potential. It is propagated through seeds, which sometimes remain stored until the sowing period. Among the various forms of storage, some aspects related to the environment and the type of material that constitutes the packaging may compromise the viability and vigor of these seeds. Therefore, the objective of this study was to evaluate the physiological quality of corn seeds stored in different types of packaging and subjected to conditions of high temperature and relative humidity throughout storage. For this purpose, water content, germination and vigor were evaluated through the cold test. A completely randomized design in a 4 x 4 factorial scheme (packaging x evaluation times) with four replications was used. Data were subjected to analysis of variance and regression, and the means were compared by Tukey test at 5% probability, using the Sisvar 5.3 statistical software. It was concluded that, in 45 days of storage, the water content in corn seeds reached values of up to 13.62%, which resulted in a reduction in the vigor due to high respiration caused by the storage temperature.
