Abstract

Striped catfish tetraploid induction through heat shock that carried out in this study is not intended to produce on growth fries.But to form a broodstock to produce triploid on growth fries through cross breeding without any physical shock induction process.The fries from the heat shock induction in the previous study were screened or selected by observing the maximum number of nucleoli in fin cells.The number of tetraploid individuals used in the performance test was 105 which were placed in three different concrete tanks.The results showed that the growth of tetraploid striped catfish was more significant than diploid with a difference in the daily weight percentage about 0.497% and 0.158% for length but insignificant differences in FCR and SR.In gonadal development based on histological observations, it was shown that each tetraploid and diploid both male and female striped catfish were at the same level of gonadal maturity.Female gonads were at the previtellogenic oocytes and vitellogenic oocytes, but males are dominated at the stage of spermatocytes and spermatozoa.This histology also shows us that the female gonad was still at the development stage, while the male had entered the mature stage and ready to be spawned.

Abstract

The development of natural adhesives derived from non-fossil resources is very important for the future. This research aimed to develop natural adhesive from maltodextrin and compare it with other natural adhesives such as citric acid and malic acid for particleboard production. The effect of the adhesive raw materials on the physical and mechanical properties of the particleboards was investigated. The sweet sorghum and those natural adhesives were used in the manufacturing of particleboard. The resin content of the natural adhesive was 20 wt% base on air-dried particles. The dimension and density target of the boards were 30 x 30 x 0.9 cm3 and 0.8 g/cm3, respectively. The particleboards were prepared by hot pressing at 200°C for 10 min. The physical and mechanical properties of particleboards were evaluated based on Japanese Industrial Standard for particleboard (JIS A 5908-2003). The results showed that the density, moisture content, modulus of elasticity, and modulus of rupture met the requirements of the JIS A 5908-2003 standard, while the thickness swelling, water absorption, and internal bond did not meet the standard requirements. The results of FTIR analysis indicated the establishment of ester linkages due to the reaction between the natural adhesive and sorghum bagasse that contributed to the excellent physical and mechanical properties of the particleboard.

Abstract

Rapid growth makes water hyacinth (WH) an exceptional biomass resource, but its low calorific value and elevated ash content hinder its application as a sustainable green energy source. This study aims to enhance the quality of water hyacinth as a solid fuel by increasing lignin content through composting and decreasing ash content by demineralization. The composting period for water hyacinth was modified to 4, 7, 11, and 15 days, followed by a demineralization process employing two solvents: water and 5% nitric acid (HNO₃). Proximate, ultimate, and chemical studies were conducted on water hyacinth before and following treatment to ascertain its specific alterations. This study indicates that after 15 days of composting, the lignin fraction increased from 10.01% to 15.14%. Demineralization employing a combination of water and nitric acid can substantially reduce ash content (19.4%). The demineralization of raw materials during composting is more efficacious in diminishing ash content than the demineralization of raw materials before composting. The most significant reduction was 46.17%, observed in the 11-day WH composting, where the ash content decreased from 22% to 11.84%. According to the results, modified WH is a viable raw material for solid fuel due to its enhanced lignin content and reduced ash level.
