Abstract

Silica gel is a compound that has two active sides, namely silanol (S-OH) and siloxane (Si-O-Si), which are still less effective as adsorbents, so modification is carried out. Silica is modified by adding sulfonate compounds with the help of GPTMS bridging compounds. This modification aims to improve the absorption capacity of Nickel (Ni2+) metal ions in the modified adsorbent, namely sulfonate-modified silica gel-GPTMS. The characterizations used are SSA (Atomic Absorption Spectrophotometry) to see the success of the adsorption and desorption process. This research is quantitative experimental research where the adsorption and desorption processes are carried out using the column method, where the adsorption process itself is carried out on the Ni2+ cation using silica gel-GPTMS Sulfonate adsorbent at an optimal concentration of 20 ppm and pH 3. Then, we continued with the desorption process, which aims to determine the optimum conditions of the desorption process, including determining the type of desorption agent (NaCl and CaCl2) and concentration for the Ni2+ cation desorption process. Based on the results of the research conducted, the optimum condition of the type of desorption agent is CaCl2 where the desorbed weight is 0.1527 mg, and the per cent desorption is 90.10%, the optimum concentration of CaCl2 is 0.025M with a desorbed weight of 0.1442 mg and a per cent desorption of 90.18%. Based on the experimental results, the sulfonate-modified silica gel-GPTMS adsorbent can still be used repeatedly for adsorption and desorption of Ni2+ cations at optimum conditions.

Abstract

This research aims to assess the role of profitability in mediating the impact of liquidity and capital structure on stock returns in food and beverage companies listed on the Indonesia Stock Exchange for the 2019-2023 period. The study population included 29 companies, and the sample taken was 26 companies using purposive sampling method. The results show that there is a significant positive correlation between liquidity and profitability, while capital structure has no impact on profitability. In addition, liquidity, capital structure, and profitability are significantly negatively correlated with stock returns. Profitability also does not function as a mediator in the relationship between liquidity, capital structure and stock returns.

Abstract

Tempeh chips are a popular soybean-based snack widely consumed by the public; however, they are potentially susceptible to contamination by heavy metals such as lead (Pb) during the production process. Pb exposure in food can pose serious health risks, making it essential to analyze Pb levels to ensure food safety. This study aims to determine the Pb content in tempeh chips using the Atomic Absorption Spectroscopy (AAS) method and to evaluate its safety based on the standards set by the Indonesian National Standard (SNI). The AAS method was employed to detect Pb concentrations in tempeh chip samples. The results showed that the Pb content in the samples was 0.029 mg/kg and 0.031 mg/kg, which are well below the maximum limit of 0.25 mg/kg as specified in SNI No. 2602-2018. Method validation indicated good linearity with an r² value of 0.9950 and acceptable precision with an RPD of 6.89%. Therefore, the AAS method is proven to be valid for analyzing Pb content in tempeh chips, and the tested samples are considered safe for consumption according to the applicable standards.
