Abstract

Nata de leri is one of the products produced from fermented organic white, red, black rice washing water with the addition of red dragon fruit skin extract. In javanese the rice washing water is called Leri so that the resulting nata is called “Nata De Leri”. (carbohydrates, proteins, minerals) that are carried away from the rice membrane during the washing process. So that it can be utilized by microorganisms as a medium in making nata. The addition of red dragon fruit skin extract gives color because it contains a lot of anthocyanin and also the fiber and water content is very high. The purpose of this research was to determine the organoleptic and chemical characteristics of nata. This research used a qualitative descriptive method using a 2 factor complete randomized design and the treatment given was 75% of white, red, black rice washing water concentration, The concentration of red dragon fruit skin extract 75%, 50%, and 25%. The results showed that the most preferred texture on the addition of 75% red dragon fruit skin extract was an average of 4,65, the most preferred color in the addition of 75% and 25% red dragon fruit skin extract, the aroma of the average panelist doesn’t like all the aroma of nata de leri, for the taste all the samples were liked by the panelists because of their sweet taste. While the water content and crude fiber content produced are quite high on average but do not exceed SNI.

Abstract

Bandar Lampung City has a population of 1.051.500 people with a density of 3.308,4 people/km2 in 2018. The population is densely accompanied by residential developments, one of which is housing. Housing in the city of Bandar Lampung amounted to 220 housing estates in 2018 consisting of types 21, 36, 45.54, and 70. Rapidly increasing development certainly affected the surrounding ecosystem. The ant is one indicator of change in the environment. Therefore it is important to research the identification of Myrmicinae ants in three types of housing in Bandar Lampung City. The research was conducted in November - October 2018. This type of research is quantitative with survey methods. The housing of each type is selected by random sampling then ant samples are taken using the standardized transect method. Two transects were installed in the yard of the house and a roadside transect. The ants obtained were identified using photographs, images and the key of determination. The results showed that there were 5 species of Myrmicinae from 3 genera namely Solenopsis geminata, Solenopsis invicta, Solenopsis molest, Tetramorium sp., and Monomorium sp. The most dominant subfamily Formicidae habitats are in the house and terrace house.
