Abstract

Aim: This study is purpose to understand the chemical and physical characteristics and pollution load in each step of tempeh wastewater: washing, boiling, soaking and mixing. Tempeh is traditional food from soybean fermentation. Tempeh has a lot of healthy contents as protein and vitamin. However, wastewater from tempeh production is discharge to river directly which considered as environmentally damaging. However, the characteristics of wastewater from tempeh production and its level of environmental impacts to environment are limitedly studied. Methodology and Results: Tempeh wastewater was analyzed in chemical and physical parameters. Chemical characteristics analyzed are pH, Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). pH was measured using pH meter, BOD using SNI 6989.72:2009 method and COD using SNI 6989.2:2019 method. The physical parameter analyzed is Total Suspended Solid (TSS) and analyzed using SNI 6989.3: 2019 method. Pollution load calculated by deviation maximum pollution load and pollution load existing. Result of this study findings indicated that the highest BOD 299.40 mg/L and COD 540.66 mg/L was found in soaking step compared to other steps in tempeh production. Highest TSS 655.20 mg/L was found in boiling step. The pH values in all steps were acidic 4 and 5. Allocation Pollution load of: TSS overall exceeded the capacity, BOD and COD overall exceeded the capacity except in washing step (BOD 304.39 kg/day and COD 857.78 kg/day). Conclusion, significance and impact of study: The Highest TSS of tempeh wastewater processes was in boiling step while the highest organic matter was detected in soaking. Further for whole pH were acidic and exceeded the standard. Allocation of pollution load for TSS, BOD and COD exceed the standard except for BOD and COD in washing waste. Overall tempeh wastewater needs treatment to prevent river pollution.

Abstract

The issue of environment and sustainable energy are two issues that have not been completely resolved until today. Liquid waste treatment technology, which can remove pollutants and produce hydrogen gas, is interesting to study since hydrogen itself is one of the energy sources whose use has begun to be developed. Aim: The following article will discuss several aspects that can be developed in each technology. Methodology and Results: Electrocoagulation and photocatalyst are both technologies which are possible to eliminate liquid pollutants while producing hydrogen in a single process. Research that attempts to combine two processes to improve the ability to treat pollutants in wastewater while producing hydrogen has been carried out. The optimization process can be carried out respectively in terms of electrocoagulation and photocatalytic technology. Modifications can also be made by combining the two processes of electrocoagulation and photocatalysis, either sequentially or simultaneously. Modification process carried out aims to increase hydrogen recovery without neglecting the ability of electrocoagulation and photocatalysis in removing organic waste. Conclusion, significance, and impact of study: This brief review provides an overview of the potential of electrocoagulation and photocatalysis technology in its ability to remove liquid waste while producing hydrogen gas. The opportunity to combine the two processes is also shown based on previous studies. The review is carried out based on an in-depth study of the research that has been done. The simultaneous use of both processes has been shown to provide much better capabilities in terms of removing liquid waste and producing hydrogen gas.

Abstract

Globalization causes multinational entrepreneurs to move their business locations across geographical boundaries. The Multinational Entrepreneurs running businesses across geographic boundaries are called Foreign Direct Investment (FDI). One factor that determines the success of FDI is the accurate choice of investment location. Currently, Climate Change plays a significant role in business decisions. Aim: This study aimed to assess the selection of investment locations using the demand-side analysis and environmental policies approach. Methodology and results: The sample was the Electronic and Automotive industry located in the JABABEKA Industrial Estate, Jakarta, Indonesia. The primary data were collected from the respondents' perceptions and processed using the Structural Equation Model (SEM) method. The SEM-PLS results showed that the path coefficient of the relationship between Environmental Regulations and the Investment Locations Choice was 0.314. Therefore, Environmental Regulation significantly affected Investment Locations Choice. Furthermore, the path coefficient of the relationship between Environmental Litigation and the Investment Locations Choice was 0.113, with a P-value > 0.05. This means that Environmental Litigation insignificantly affects the Investment Locations Choice. Conclusion, significance, and impact: Environmental regulations and litigation affect the location selection by investors. Therefore, urban planners should formulate policies for providing better waste and air pollution treatment facilities in each industrial area to increase the attractiveness of Indonesia as a Host Country.

Abstract

Unmanaged waste can cause various problems of environmental damage including threatening tourism development. The current waste problem is quite worrying because it can have a direct impact on humans, such as the entry of plastic elements into the human body through fish or food exposed to microplastics. Aim: The waste bank around Lake Tondano tourism object was studied qualitatively with the aim of describing the waste bank management mechanism to be used as a model for developing a waste bank to support sustainable tourism development. Methodogy and Results: The research data was obtained through field research through observations and interviews with waste banks around the Tondano lake tourist attraction, in this case the Mapalus waste bank located in Papakelan Village. Conclusion, significance, and impact study: The results show that the current form of waste bank management on the shores of Lake Tondano is a waste bank that is purely managed by the community. The form of management is to collect waste from the community by first going through a sorting process. After sorting, organic waste is used as fertilizer and inorganic waste is made into valuable products and can be used as souvenirs for tourists. The waste bank program can reduce the increase in waste directly from the source. In addition, the waste bank can produce new products and provide benefits to the community. The waste bank is also a solution in the context of developing tourism on the coast of Lake Tondano.
