This study aims to evaluate the existing conditions of electronic waste management in Indonesia and compile recommendations for electronic waste management programs in Indonesia. This research was conducted by collecting primary data from questionnaires and collecting secondary data from the literature on electronic waste management in developed countries (United States, Japan, and Switzerland) and Indonesia. The collected data were compared and analyzed for compiling strategy in the SWOT (Strengths, Weaknesses, Opportunities, Threats). Recommendation programs for electronic waste management in Indonesia were established based on SWOT Matrix. The evaluation results show that the existing conditions of electronic waste management in Indonesia are lagging compared to developed countries. The management recommendation program provided is the 4R programs (Reduce, Reuse, Recycle and Remove) for electronic waste; Dropbox to collect electronic waste; Development of formal electronic waste management infrastructure; Industrial revitalization / private electronic waste recycling facilities; Development of electronic waste landfill; Application of economic instruments for electronic manufacturers; Extended Producer Responsibility (EPR) for electronic equipment; Trade-in for all electronic products; and cooperate with the informal sector.\u0000Keywords: Developed countries, Electronic waste, Program recommendations, SWOT analysis, Waste management.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75621848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature of fish that is able to adapt quickly to transfer from pond to pond makes many residents choose to breed fish over other livestock. Many types of fish can be cultivated well, but most people choose to cultivate goldfish. Goldfish have an economic value that is quite tempting for the community. There are some fish that have a higher economic value, but people are more extra in maintaining them, for example in terms of feed. Goldfish can be fed only when the sun is hot. If the sun does not come out, then the goldfish should not be fed because it can cause the fish to die. Besides that, goldfish only need water flowing into the pond for fish oxygen. The number of people who breed fish, there are also many irresponsible people. The reason is, when the fish begin to grow up, many fish begin to disappear, making people nervous and hot. Based on the above problems, it provides a very potential opportunity to create a tool that can overcome community unrest. Fish farming theft detection tool which is an innovative tool to overcome or find out the perpetrators of theft. Thus, hopefully the tools used can reduce the risk of stealing fish and reduce the losses of fish cultivators.","PeriodicalId":7884,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74231280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
