adsorption is a method of waste treatment that has the potential to remove toxic heavy metals. One of the factors that influence the occurrence of the adsorption process is the presence of a biological material called a biosorbent. The adsorption method is a method of absorbing heavy metal contamination in liquid waste that is very efficient and effective, as well as easy and cheap economically because of the use of biomaterials that are very cheap and can be regenerated. Chicken egg shell contains Calcium Carbonate (CaCO3) of 98.41% and has natural pores of 10,000 to 20,000 so it is estimated that it can absorb solutes. Based on the known mineral composition, chicken egg shells are composed of CaCO3 (98.41%), Ca3(PO4)2 (0.75%), and MgCO3 (0.84%). So it can be seen that chicken egg shells have a high calcium carbonate content, where calcium carbonate is a polar adsorbent. The optimum conditions for each variable in contacting broiler egg shells that have been activated with Cu2+ metal ions are optimum at pH 4, concentration of 250 ppm.

Silica or silicon dioxide is a chemical compound with the molecular formula SiO2 which can be obtained from the synthesis of crystals, silica minerals, and vegetables. Compounds resulting from the polymerization of silicic acid, which are composed of a tetrahedral SiO4 unit chain with the general formula SiO2. Each silica atom is surrounded by four oxygen atoms. Silica forms a polyhedral network, where the bonds between oxygen tetrahendral are one and the other. Silica will form a framework that has pores that are quite open and allow other molecules to enter and undergo adsorption on the surface of the silica. Modification of silica is done by adding heat at a certain temperature, adding reagents to the active site of silica will change the silica functional group. Silica with the addition of amine compounds reacted with GPTMS can be used as nitrate anion adsorption to see the absorption capacity of silica against nitrate anions using the batch method. The factors used to see this adsorption capacity include pH at pH 7 with an absorption of 1.931463 mg/g and the percentage of absorption is 79.5%. and contact time with a time of 90 minutes with an absorption of 0.32677 mg/g and the percentage of absorption is 67.28785%.

— Silica gel is one type of dry silica gel which is widely used as an adsorbent. Silica has the ability to absorbsi because it has two active site groups that can be activated, namely a silanol group and a siloxane group. This modification was carried out to increase the ability of silica to absorbsi ions, one of which was phosphate anion. In waters, very high levels of phosphate anion can disrupt the marine biota ecosystem because it can cause eutrophication or decreased oxygen levels that enter the waters. The modifier compound used is dimethylamine (DMA). Silica and dimethylamine can bind to several linking compounds, namely glycidopropyltrimethoxylan (gptms). The modified silica was characterized by FTIR and the absorption results were analyzed using a UV-Vis spectrophotometer. The results of the comparison of the absorption capacity of phosphate anions after modification are greater than before modification, where the absorption capacity of silica before modification is 1,2601 mg/g with an absorption percentage of 54,46% and silica after modification is 1.9686 mg/g with an absorption percentage of 1,9686 mg/g. 85,08%.

— Research on increasing the degradation ability of AC-ZnO catalyst against Rhodamine B by impregnation on activated carbon from coconut fiber (Cocos nucifera L) has been carried out. Activated carbon is catalyzed by ZnO semiconductor catalyst by impregnation method. Impregnation was carried out by varying the addition of activated carbon (AC) 5%, 10%, 15%, 20% and 25% ZnO mass for 6 hours. The catalyst was calcined at 300 C for 105 minutes. For the results of the AC-ZnO adsorption test on Rhodamine B, the catalyst was tested on the degradation of Rhodamine B solution (10 ppm) with UV irradiation. obtained 89.76%. This shows that activated carbon from coconut fiber can support to increase the role of ZnO in the degradation of Rhodamine B. Characterization of the optimum degradation yield was carried out by FTIR. The characterization results showed that the ZnO catalyst was successfully formed.

— Alumina has a wide range of industrial and technical applications and can be extracted from different locations, materials and methods. Napa soil from the Pesisir Selatan has been used as a raw material for alumina production. This alumina extraction process is the result of modifications to several methods including alkali fusion and hydrothermal methods. Napa soil is calcined at 750 0 C for 4 hours and washed with hydrochloric acid 1,5 M; 2 M; 2.5 M at 95 0 C, followed by alkali fusion by NaOH 10 M so that it is obtained Al(OH) 3 and converted to Al 2 O 3 with the calcination of 1100 0 C. The extraction results are characterized by XRF technology to understand the content of the analyzed sample. The extraction mass of alumina with different concentrations of HCl 1 M; 1,5 M; 2 M; 2.5 M is continuous 14,171 g; 41,127 g; 31,711 g; and 0 g. The result of XRF analysis of alumina extraction showed that the Al 2 O 3 content increased by 68.42%.

Rendang is one of the typical foods of the Minangkabaunese in West Sumatra. Many people like to consume rendang because rendang has a distinctive taste because in making rendang the type of meat, coconut milk and spices used greatly affect the aroma and taste produced. The purpose of this study was to determine the level of aroma, color, texture, and taste of beef rendang with variations in the addition of Cinnamomum verum. The hedonic test of beef rendang with variations in the addition of C. verum was carried out on 50 panelists. Panelists present 6 samples with 6 different sample numbers. Panelists were asked to rate how much preference there was for the product using a hedonic scale. The hedonic test results showed that the less C. verum added, the better the taste produced. As for the aroma and color, there is no significant difference among these products
