Abstract

Research on the proximate carbon analysis of sago fiber waste has been carried out. This study aims to determine the chemical properties of sago fiber activated carbon. Activated carbon was prepared using the hydrothermal cabonization method. Activation is carried out chemically using KOH and followed by calcination at a temperature of 500°C. Proximate analysis was carried out to determine the chemical properties of the carbon produced. In this study, the water, ash, volatile and bonded carbon content were 6.67%, 21.22%, 17.8% and 45.79%, respectively.

Abstract

Betok fish (Anabas Testudineus) is a fish with high protein but there is no information about the albumin content in betok fish. This study aims to determine the albumin of Betok Fish (Anabas Testudineus) in Cenning, West Malangke District, North Luwu Regency. The measurement of albumin used the Lowry method with samples of adult fish of different sizes. The albumin content increases with increasing length and width of fish.

Abstract

This study aims to determine the heavy metal content of mercury (Hg) and cadmium (Cd) in the freshwater mussel (Pilsbryoconcha exilis) in the Lamasi Pantai village, Luwu district. This type of research is descriptive research. The instrument used in this research is ICP-MS. The results of the analysis showed the levels of heavy metal Cadmium (Cd) in fresh water mussel (Pilsbryconcha exilis) at the sample station I 0.04 ppm, station II 0.03 ppm, station III 0.06 ppm. The levels of heavy metal Mercury (Hg) at stations I, II, and III were <0.0005 ppm respectively. These results indicate the content of heavy metals contained does not exceed the SNI quality standard of 1.0 ppm.
