One of the efforts to reduce the occurrence of these problems can be done through one of the green building , namely water conservation and efficiency. According to Yudo, saving water is a very important effort to avoid water scarcity. In addition, saving water is an effort to use water efficiently. Therefore, this study was conducted to analyze the application of water conservation and efficiency in the Tower LawThe data collection method used in this study was based on interviews, observations and measurements. The data obtained will be analyzed for water conservation which is applied to towers legal existing Greenship building and water efficiency levels using the Excellence in Design for Greater (EDGE) system. Based on the results of the analysis carried out on tower , the results of the application of water conservation with the Greenship existing building standard only got 11 points out of a maximum total of 20 points. In addition, the application of water efficiency that has been carried out tower based on the EDGE system obtained 24.28% water efficiency measures. From the results of the analysis, it was found that tower has not met the criteria for water conservation well but has met the level of water use efficiency based on the green building .","PeriodicalId":167113,"journal":{"name":"Journal of Applied Science, Engineering, Technology, and Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129525920","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}

A vertical garden is an efficient solution with a vertically modern garden concept that the functions of green open spaces can be fulfilled. The irrigation system in a vertical garden gives a major role because plants can be grown well if they have a great irrigation system. Drip irrigation is one type of irrigation system that is widely applied and the best method that has been used in the world because it is considered more efficient with a small discharge, can reduce runoff, and can reduce water loss due to evaporation. This study aims to analyze the uniform of water distribution in the drip irrigation system and the average variation of water distribution in the row and column direction using a statistical test with Kruskal-Wallis. Based on the statistical analysis, it is obtained the coefficient of variation (Cv) of 0.27, the uniformity statistic (Us) of 73.2%, and the coefficient of uniformity (Uc) of 71.7% which means that the three parameters are categorized as good and acceptable while for statistical tests Kruskal-Wallis has a difference in the average variation of water distribution for the row and column groups.","PeriodicalId":167113,"journal":{"name":"Journal of Applied Science, Engineering, Technology, and Education","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122238172","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}

Non-biodegradable plastics cause the accumulation of large amounts of plastic waste Solutions that can reduce plastic waste by making plastics that are easily biodegradable. In this study, tofu liquid waste is used as a basic material for the manufacture of bioplastics. Tofu liquid waste is waste generated from tofu production. This study aims to determine the effect of adding bacterial cellulose and chitosan on the manufacture of bioplastics from liquid waste tofu (whey) in terms of tensile strength, elongation, water solubility, and functional groups (FTIR) in accordance with PET plastic standards (Polyethylene terephthalate). The research procedure on the effect of adding bacterial cellulose and chitosan on the bioplastic fabrication of Nata De Soya. First, from tofu liquid waste, Acetobacter Xylinum starter was added and then fermented for 10-12 days to become Nata De Soya. After that it was neutralized with aquadest, removed the water by pressing, and dried to become bacterial cellulose. The process of making bioplastic with the addition of chitosan (grams) 2,3; 3.1; 3.9; 4.7 and 5.5 and bacterial cellulose (grams) 0.5 ;1.5; 3.9; 7; and 11. In the manufacture of bioplastics with the addition of Bacterial Cellulose and chitosan, it is appropriate, namely the tensile strength obtained will increase and the solubility in water decreases. From the results of our research, the best results were obtained in the addition of S5K5 with a tensile strength value of 9.665 MPa, an elongation value of 31.3%, and a solubility value in water of 17.9%. It has a higher tensile strength, smaller elongation and lower water solubility. The effect of the addition of chitosan on the tensile strength value can increase the tensile strength (Tensile Strength Value), the addition of bacterial bacterial cellulose and chitosan can affect the elongation of bioplastics getting smaller and the effect of chitosan can reduce solubility in water. It is good but still far from the standard PET (Polyethylene Terefelat) which is 60-80 Mpa.","PeriodicalId":167113,"journal":{"name":"Journal of Applied Science, Engineering, Technology, and Education","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121967260","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}
