A study on the description of silver (Ag) levels in liquid waste fixer originating from a radiology installation before being processed at the Waste Treatment Installation is sometimes necessary to avoid environmental pollution. The time and place of this research were conducted at the radiology installation for approximately 1 (one) month. The purpose of this writing is to determine the description of the silver (Ag) levels of fixer in the radiology installation. This research method is field observation. and the processing of silver levels was carried out at the Medan standardization research agency (baristand) with researchers sending samples of 100 mg/l to be tested for silver levels. The thing studied in this study was to determine the description of silver levels using the Atomic Absorption Spectrophotometry (AAS) method. From the observation results after processing, the Ag content was 0.03 mg/L. After processing, the silver content was allowed to be discharged directly into the environment or public channels because the results were still below the established quality standards, namely 5.0 mg/L. However, it would be better if each hospital was advised to process the liquid waste at the Wastewater Treatment Plant to avoid environmental pollution.

Kuliah Kerja Nyata (KKN) program in Wonorejo Village, Karanganyar District, Kebumen Regency, aims to bridge academic theory with community practice through the preservation of pandan leaf weaving crafts and the strengthening of local SMEs. This program involves students from Universitas Muhammadiyah Purwokerto for 32 days, focusing on increasing youth interest in traditional crafts and innovating product packaging. Methods employed include observation, field research, and training. Results indicate a decline in young artisans and a need for innovative packaging designs to improve product marketing. Social learning and innovation theories are used to encourage youth participation and enhance product appeal. The program faces challenges in attracting youth interest and the need for appropriate training. In conclusion, KKN successfully applies social and economic theories to address local issues, resulting in social changes that include economic development, skill enhancement, and the creation of a sustainable community.

This research aims to determine the effect of Economic Value Added (EVA) and Market Value Added (MVA) on stock prices. The population of this research is the financial report of PT Telkom Indonesia Tbk which was taken from the official website. Based on sampling in this research, the samples used were Economic Value Added (EVA) and Market Value Added (MVA), and stock prices with a period of 12 years, namely in 2012-2023. Secondary data is in the form of the company's annual report/sustainability report. This type of research is a quantitative type that is associative in nature. The data analysis technique used is multiple linear regression analysis, classical assumption test, t test, F test, and coefficient of determination test, processed using SPSS 25. Based on the results of data analysis it can be stated that Economic Value Added (EVA) and Market Value are simultaneously Added (MVA) has an effect on share prices. Partially, it shows that Economic Value Added (EVA) has a t value of 2.238 < t table 2.228 and a significant value of 0.052 > 0.05, which means it has no influence on the share price at PT Telkom Indonesia Tbk and Market Value Added (MVA) has a t value of 8.134 > ttable 2.2248 and a significant value of 0.000 <0.05, which means it has a positive and significant influence on the share price of PT Telkom Indonesia Tbk in 2012-2023.

Salt is a source of electrolytes and iodine which are very important for the human body. East Kalimantan Province has the potential for diverse coastal and marine resources with high economic value, so it has great potential for optimal, effective, efficient and sustainable management. This research aims to determine the compound content of krosok salt that will be distributed to the public with NSI. This research method is based on NSI 3556:2016 and Atomic Absorption Spectrophotometry (AAS) method, including: (1) Water content analysis; (2) Analysis of the part that is not soluble in water; (3) NaCl content; (4) KIO3 levels; (5) Analysis of metal contamination. This research was conducted on krosok salt in Kersik Village, Kutai Kartanegara Regency. The NaCl salt content does not meet the minimum NSI requirements, namely 94%. Meanwhile, Pb, Cd, metal contamination meets the requirements with values ​​below 10 mg/kg and 0.5 mg/kg.

Along with increasingly rapid technological developments in our country, the number of existing industries is increasing. Apart from producing useful products, this industry also produces waste. The waste produced contains a lot of heavy metals, one of which is the heavy metal lead. If the lead metal in the waste receives little treatment, this can cause pollution in the environment, even though this waste is present in small quantities, the lead condition is unstable and if it accumulates in the body, it can ultimately trigger cancer cells (carcinogenic) which can be dangerous for health. . In this research, adsorption of PB2+ ions was carried out on canned ground meat, where heavy metal contamination occurred in the ground meat. This research aims to determine the effectiveness of the absorption of heavy metals (Pb) contained in ground beef and their characteristics. The uptake of PB2+ ions in ground beef, measuring the concentration of PB2+ ions before and after receiving treatment, was carried out using an instrument, namely AAS, at a wavelength of 217nm. The research results showed that the effectiveness of ground beef in absorbing PB2+ ions in canned food was as high as brand a: 0.023; brand b: 0.009; brand c: 0.006
