Soap serves to kill germs so that the skin surface becomes clean. Therefore, soap usually contains Triclocarban which functions as an antibacterial agent. However, this substance can cause bacterial resistance to antibiotics if used for a long period of time. Therefore, it is necessary to substitute this chemical substance which is more natural such as red Rosella plant flower extract (Hibiscus sabdariffa L.). The purpose of this study was to analyze the effectiveness of the addition of Rosella flower extract on the physicochemical quality of liquid soap. The research method is experimental laboratory. The formulations of red Rosella flower extract used were 0%, 0.5%, 1%, 1.5%, and 2%. Soap was tested for physical characteristics, namely color and aroma, while testing chemical characteristics with a pH test. Data analysis was carried out descriptively qualitative. The results showed that the addition of Rosella flower extract proved effective in changing the physical characteristics of soap, namely odor and color. The higher the percentage of red Rosella flower extract formulation added, the more red-colored the soap and the more the soap has a distinctive Rosella flower aroma. The higher the percentage of red Rosella flower extract formulation added, the pH of the soap is closer to neutral. Soap with a pH that tends to neutral pH is better for the skin because it does not damage the lipid layer of the skin surface. Based on the results of this study, it can be concluded that red Rosella flower extract (Hibiscus sabdariffa L.) is proven to effectively improve the physicochemical quality of liquid soap","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"78 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139270973","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}

Its populations were exposed to extinction risk caused by human activities. Thus, conservation efforts such as ex-situ conservation were needed to preserve this species. One of the javan langur ex-situ conservation in Yogyakarta is the Gembira Loka Zoo. In captivity, animals must be guaranteed to be free from hunger and stay nourished. One aspect to support this welfare is food supply. Therefore, this study aimed to identify the food composition and analyze the correlation between food preference and feeding duration of each food item group. We used scan animal sampling method with five minutes intervals to observe the behavior of seven individuals of captive javan langurs. The result showed that there are three groups of food (fruit, vegetable, and leaf) provided daily to javan langurs in Gembira Loka Zoo. All the individuals spent most their time to consumed food from vegetable group, except for infant female who had the highest duration in the leaf group. In addition, based on which food they consumed first every feeding time (preference food), javan langurs preferred vegetable over fruit and leaf. Based on the Spearman correlation test, there are positive correlations of duration and preference of feeding except for leaf groups. This result was different from the natural food composition of javan langurs which mostly consisted of leaves. This study might help the zoo to consider the food items provided for the animals to increase animal welfare.","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139283944","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}
