Sawdust is one of the industrial wastes that can be used as an absorbent. The chemical content in sawdust is the same as in its wood, i.e lignin, cellulose, and hemicellulose. This study aimed to determine the optimum contact time, optimum weight, and adsorption capacity of Cu (II) ions by teak sawdust using the atomic absorption spectrophotometry (AAS). Determination of optimum contact time was carried out with time variations of 10, 30 and 60 minutes, the optimum weight with various weight of 0.5, 1, and 1.5 grams, and the adsorption capacity of teak sawdust in various concentrations of 50, 100, 150 and 200 ppm. The results showed that the equilibrium contact time was reached at 30 minutes, and the percentage of adsorption of Cu (II) was 91.25%. The optimum weight for metal adsorption was 1.5 gram, and the adsorption percentage of adsorbed Cu (II) ions was 96.18%. The adsorption capacity was determined from the adsorption isotherm according to the Langmuir and the freundlich models. The adsorption isotherm model of Cu (II) of teak sawdust follows the Langmuir isotherm model with a maximum adsorption capacity (qmax) of 2.058 mg/g.

Wood sawdust is one of the wastes from wood processing industry such as sawdust and peel residues. They are cheap raw materials and potential as a source of alternative energy by processing it into charcoal briquettes. The use of charcoal briquettes as a substitute for fossil energy sources has several advantages including the relatively less smoke emitted because it has been released during the carbonization process. They can be stored for a long time and the calor value is higher than wood. Charcoal briquettes are made from wood sawdust which is added by tapioca flour as glue. This study was conducted in two main stages, processing charcoal briquette and characterization. The characterization of charcoal briquettes are including density, moisture, ash, volatile substances levels, carbon bound, long flame and calor value. The results obtained from the charcoal briquettes are a density of 0.384 gr/cm3, a moisture of 2.44%, an ash of 4.82%, a volatile substance of 19.13%, a carbon bond of 74.44%, a briquette flame of 6.75 minutes/gr and the calor value of 5127 cal/gr. This study concluded that wood sawdust briquette has the potential to be used potentially as substitued for fuel.

Penentuan Kadar Total Flavonoid Kunyit Putih (Curcuma zedoria Rosc.) dengan Variasi Jenis Pelarut Evayana Evayana; Sitti Aminah

Determination of Total Levels of White Turmeric Flavonoids (Curcuma zedoria Rosc.) with Variation of Solvent Types. White turmeric (Curcuma zedoria Rosc.) is a herbal plant that has many health benefits in healing several diseases. It can grow wild in the open with moist soil. The purpose of this study was to determine the total levels of white turmeric flavonoids with various types of solvents. The solvents used in were water and ethanol. The quantitative test of flavonoids in the White Turmeric extract used a quercetin standard solution curve. The samples were analyzed by UV-Vis spectrophotometry at a maximum wavelength of 435 nm. The average yield obtained in the water extract was 0,073% and 0,102% in the ethanol extract. Keywords: Flavonoids, White Turmeric, UV-Vis Spectrophotometry

This study aims to determine whether the analyzed clean water meets the quality standard requirements set by PERMENKES RI No. 492 of 2010. The parameters measured in this study were pH, odor, temperature, color (in-situ testing) as well as iron and hardness which were tested ex-situ using Atomic Absorption Spectrophotometry and Complexometric Titration. The results of this study are the springs on the S. Parman road for the parameters of pH, color, hardness, and iron, respectively 8.26 pH; colorless; 120 mg/L; and 0.129 mg/L, where the results met the requirements but for the odor (fishy) and temperature (36oC) parameters did not meet the quality standards. Meanwhile, the water sources in the Besusu Tengah Village, which existed before the earthquake in Palu City, had met the requirements set by the government

Analysis of Fatty Acid Content of Eel (Anguilla Bicolor) from Lake Poso. Skipsi, Chemistry Education Study Program, Department of Mathematics and Natural Sciences Education, Tadulako University, Palu. Advisor Sri Mulyani Sabang. The purpose of this study was to determine the fatty acid content of eel (Anguilla Bicolor) originating from Lake Poso. The method used to analyze the fat content was the shoxletation extraction method. The results showed that the fat content of eel (Anguilla Bicolor) from Lake Poso = 1.94%. Meanwhile, to determine the fatty acid composition of eel, it was analyzed using gas chromatography with the composition of fatty acids found in eel (Anguilla Bicolor) including saturated fatty acids 51.89%, monounsaturated fatty acids = 42.68%, and unsaturated fatty acids. plural saturation = 7.99%. Eel has many benefits for the human body, eel meat is rich in protein, vitamins, fatty acids, and micro elements (minerals). The content of vitamins in eels include vitamin A, vitamin B1, and vitamin B2, as well as micro elements such as Zn (Zink). In addition to vitamins and micro elements, eels also contain unsaturated weak acids needed by the body, including omega fatty acids which are useful for the development of children's brain cells.

Mercury metal (Hg) is included in the heavy metal group which is toxic because it has neurotoxin properties for living things. As a heavy metal, mercury (Hg) will be difficult to decompose if it enters the waters, mercury (Hg) will also form deposits in sediments. Mercury is found in nature and is found in soil, water and air. Mercury is rarely found in its free form in nature but is in the form of cinnabar (HgS) seeds. Mercury metal is usually easy to find in mining areas, such as in gold mining areas. Gold mining is one of the activities that can increase people's income, but gold mining can be detrimental if in its implementation it is not followed by a good gold processing waste treatment process. The method used in this research is cold vapor atomic absorption spectrophotometry. The results obtained in this study are the metal content of miner 1 as many as 3 samples. Sample 1 has a concentration of 1.2594 ppm; sample 2 has a concentration of 0.4924 ppm; and sample 3 has a concentration of 0.2091 ppm. Miner 2 as many as 3 samples of which sample 1 has a concentration of 1.0260 ppm; sample 2 has a concentration of 0.3401 ppm; and sample 3 has a concentration of 0.3152 ppm. And miner 3 has 3 samples where sample 1 has a concentration of 0.7215 ppm; sample 2 has a concentration of 0.2464 ppm; and sample 3 has a concentration of 0.3461 ppm. The results obtained from the calculation of metal concentrations of mercury (Hg) show that the water of the Janja river has been contaminated with heavy metals, namely mercury (Hg). This is due to mining in the Janja river.
