This research was conducted because of the emergence of cases of environmental pollution due to excessive production activities and the lack of awareness of business actors towards environmental conservation. Since the emergence of COVID-19 in Indonesia, the demand for medicines and other consumer products has increased. Public demand for companies to continue to care about environmental sustainability to reduce the negative impact of company activities on the environment. One concept that can be applied by management to handle problems that occur between the environment and the company is the concept of eco-efficiency. The purpose of this study is to, first, test the effect of eco-efficiency on firm value, second, test the effect of eco-efficiency on firm value with profitability and leverage as moderating variables. The sample of this research is manufacturing companies in the consumer goods sector listed on the Indonesia Stock Exchange in 2020-2023 using purposive sampling method. This research analysis method uses simple regression analysis and moderating analysis regression (MRA). This study provides evidence that environmental management implemented by the company can significantly provide good company value, besides that the high level of profit earned by the company can moderate the relationship between eco-efficiency and company value with a positive effect but in this study leverage cannot moderate the eco-efficiency relationship.
 
 

Household sewage treatment in Surakarta City depends on the performance of the available domestic wastewater treatment plants (IPAL), including Pucangsawit IPAL, Semanggi IPAL, Mojosongo IPAL, and UNS IPAL. Each of these IPAL’s serves a specific area, such as the UNS IPAL which serves the UNS area and its surroundings, the Mojosongo IPAL which is in charge of the North Area of Surakarta, the Semanggi IPAL which takes care of the South Area of Surakarta, and the Pucangsawit IPAL which serves the Central Area of Surakarta City. This research aimed at the effectiveness of the performance and development plan of each IPAL in the next 20 years. This research used descriptive qualitative and quantitative analysis methods. Qualitative descriptive analysis was conducted by observing the existing condition of IPAL Komunal in the research location. Quantitative descriptive analysis in this study was carried out by testing samples at the inlet, aeration, and outlet points of the IPAL. Based on the quality standards of the Minister of Environment and Forestry Regulation number P 68 of 2016, each IPAL. UNS IPAL is 47.27% for BOD, 73.81% for COD, 76.36% for TSS. Mojosongo IPAL is 88.71% for BOD, 76.50% for COD, 78.57% for TSS. Pucangsawit IPAL was 91.88% for BOD, 83.20% for COD, 74.82% for TSS. Semanggi IPAL is 20.45% for BOD, 69.95% for COD, 69.05% for TSS. Alternative development at the IPAL that can be done to prepare for the next 20 years is to increase the volume in the initial settling basin, aerobic biofilter basin, and also the final settling basin. 
 

Android is an operating system whose capabilities continue to increase from year to year. The capabilities of Android currently match the capabilities of a computer. Not only limited to ordinary computers, what a server computer can do can now be done on Android, including making Android a web server. So it is possible for people who have Android to have their own web server. The problem that arises is that the web server on Android cannot be accessed directly via the internet. Cellular operators do not provide Public IP to their customers, so a way is needed so that the Android web server can be accessed on the internet, one of which is by using Virtual Private Network (VPN) technology. The aim of this research is to make the web server on Android accessible on the internet. The method used is to combine a Virtual Private Server (VPS) and Android using VPN. The research results showed that VPN can be a bridge so that the web server on Android can be accessed from the internet.  

This study aims to analyze the impact of administering commercial probiotic bacteria on the wastewater from tofu industries on changes in Bio-logical Oxygen Demand (BOD) and Dissolved Oxygen (DO) levels. Tofu industry wastewater is known to have high BOD and low DO levels, which pose a potential environmental pollution risk. This study used a pure experimental method with variables including the ratio of tofu industry wastewater to commercial probiotics (1:1, 1:2, 1:3) with an incubation interval of 8 hours. The results showed that the administration of commercial probiotic bacteria significantly reduced BOD levels and increased DO levels in the wastewater. The 1:3 ratio of tofu industry wastewater to commercial probiotics showed the most optimal effect in increasing DO and decreasing BOD. An incubation time of 32 hours showed the most optimal effect in increasing DO and decreasing BOD. The 1:3 volume ratio between tofu wastewater and probiotics (25% tofu wastewater and 75% probiotics) proved to be the most effective, with the highest DO increase of 2.51 mg/L and the largest BOD decrease of 144.20 mg/L. In addition, incubation time also had a significant effect, the longer the incubation time, the more optimal the probiotic activity in reducing BOD levels and increasing DO levels. The conclusion of this study is that the administration of commercial probiotic bacteria at a 1:3 ratio and an incubation time of 32 hours is an effective way to improve the quality of tofu industry wastewater.
