This study used rice-washed water as the main ingredient for producing toner. Rice-washed water is the main ingredient because it contains abundant nutrients such as carbohydrates in the form of starch, fat, protein, gluten, cellulose, hemicellulose, sugar, vitamins, and minerals. This study aims to determine the effect of toner application made from rice-washed water on the skin, storage time on toner quality, and the production process. The method used in this study uses a simple method of soaking with a rice/water with a various ratio (kg/L). The analysis results show that the toner has a pH of 6.4, considered safe for all skin types with good moisture. The effect on skin moisture was analyzed on six respondents. The toner has a viscosity that is not too thick with a cloudy white color caused by rice grains. Rice grains are beneficial for the skin because they can regenerate skin cells. Rice-washed water toner for seven days contains fat, manganese, protein, oil, fat, and is odorless.","PeriodicalId":17766,"journal":{"name":"Jurnal Sains dan Terapan Kimia","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84425773","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 study was conducted at the Center for Research and Development of Post -Harvest Agriculture, Bogor. Experiments were arranged in the split split plot design with a complete random design (RAL). Comparison of water with sago starch as the main plot, the α-amylase enzyme as a plot child and the glucoamilase enzyme as a plot child. Research is divided into two experiments, (1) ratio of water and sago starch (2) comparison of enzymes and sago starch. The results showed the ratio of starch and water, the dose of the α-amylase enzyme and glucoamylase had an effect on the value of brix, color and total sugar levels in both types of sago. The ratio of starch and water 1 : 4 with the dose of α-amylase enzyme 1 ml/kg starch and the enzyme glucoamilase 1 ml/kg starch is an optimal condition for making liquid sugar from the Fasampe sago starch. The ratio of starch and water 1 : 4 with the dose of α-amylase enzyme 1.2 ml/kg of starch and the glucoamilase enzyme 1.2 ml/kg of starch is an optimal condition for making liquid sugar from Fafion sago starch.

This condition is very influential on the sustainability of SME business.The development of marketing strategies is one of the alternative solutions that are expected to help farmers and SMEs entrepreneurs in the processed of derivative products to survive and develop their business. Not stopping at the application of digital marketing application only, research on measuring the consumer satisfaction index is also carried out related to the products marketed and the use of digital marketing applications is expected to help obtained information related to the marketing goals to be achieved and find out the amount of consumer satisfaction index resulting from services that have been provided and products consumed. The research that using the Customer Satisfaction Index (CSI) analysis method showed a consumer satisfaction value index of 80.523% which has meaning that consumer has already feel satisfied.

The distinctive taste is caused by the presence of secondary metabolite compounds present in coffee cherries. The content of secondary metabolite compounds in coffee is formed when it becomes coffee cherries, in the post-harvest process, and the roasting process of coffee beans. Several regions in Indonesia are coffee bean producing areas, including Aceh, Bogor, Bandung, Situbondo and Temanggung. The purpose of this research was to determine the content of phytochemical compounds, total phenol content, and antioxidant activity in the five samples of Arabica coffee beans with the natural process which were roasted at the same light to medium roasting level.

Modified hanjeli flour is produced from the following process, when raw hanjeli seeds are soaked in sodium metabisulfite (Na2S2O5) at concentrations of 50, 75 and 100 ppm for 36 hours, steamed, roasted, ground and sieved.
