Abstract

Mackarel tuna is one of the fish that is quite abundant in Banyuwangi, its existence in the Java and Bali seas is found throughout the month, therefore the use of mackerel tuna fish into processed food products is often made by the community. In addition to being a valuable product, mackerel tuna fish bones can be processed into other products that are useful in agriculture, namely organic liquid fertilizer. This study was conducted on a laboratory scale with four different treatments (length of fermentation time) including 5, 10, 15, and 20 days, where each treatment was repeated 4 times. The purpose of the study was to find out the best phosphorus and calcium content from four different treatments. The results of the study found that the best fermentation period of liquid organic fertilizer was on the 20th day of fermentation with a value of phosphorus (P) content of 0.091%, calcium (Ca) of 0.377%.

Abstract

De-Djawatan Tourism Destinations are known by various tourists both local and non-local with their natural beauty in the form of large and lush trees that are still beautiful or natural. De-Djawatan tourism does not yet have detailed information either manually or digitally related to the biological and general classification of plants in that location. As smartphone technology develops, the information needed to be very easy to obtain. QR Code is one method to obtain complete information. QR Code is a type of two-dimensional image that displays data in the form of text. This community partnership program aims to provide appropriate technology in the form of the QR code method in determining the identification of plants found in De-Djawatan tourist destinations. This aims to make it easier for tourists to find information on various plants both biologically and in general. The stages of program implementation start from the observation stage, media creation, and implementation. The results of this program using the QR Code can include the identity of the identification results of plants, such as division, order, family, genus and species of plants in the De-Djawatan location. In this QR Code method there are features such as Home, Collection, and Admin. Before the QR Code is created, the document data is encrypted and then used as a QR Code. The result of scanning the QR Code is in the form of a Uniform Resource Locator (URL) that points to the document data. When the URL is executed on the web browser, the system performs a description of the URL, then it is matched with the database, and then displayed to the web browser. The final result is a Document Validation application in the form of a QR Code which is used to convey plant identification information, such as division, order, family, genus and species of plants.
