Abstract

Banana skin contains nutrients that are high enough, especially in vitamins and minerals so that they can be used as raw material for food by processing it into flour. Banana skin flour can be used as a variety of processed foods. This study aims to develop snack alternatives for children aged 6-24 months in the form of MP-ASI biscuits with basic ingredients of Ambon banana peel and the addition of sweet potatoes in the hope that in addition to increasing nutritional value it can also increase the added value of the waste. This study uses experimental design carried out in March to November 2018. The flow of research includes (1) First Phase, namely the proposition research and (2) The second stage, namely the main research. Preliminary research includes preparation of tools and materials, then making basic ingredients namely banana peel flour and red sweet potato flour, as well as determining biscuit formulations. While the main research includes organoleptic tests (hedonic quality and acceptability), nutritional value tests (proximate test for macro nutrients and β-carotene test using HPLC), and tests of TPC (Total Plate Count) microbial contamination. The results showed that biscuits made from banana peel and red sweet potato met the SNI standard for MP-ASI so that it can be recommended for food for infants aged 6-24 months, but the temperature of storage, processing and packaging must be considered to be able to meet the requirements for food safety.Keywords: banana skin ambon, red sweet potato, mp-asi biscuits, baby food

Abstract

Observation on abundance of diatom has been conducted in Gumilamo-Magaliho waters, North Halmahera. The aims of this study were to identify and analyze daily fluctuations of diatom abundance also analyze the biological indices in the plankton in that waters and . Sampling was conducted at three stations representing the strait, mangrove areas and estuary. Plankton were collected using a plankton net no.25. Sampling was carried out for 24 hours with six hour interval. Identification and counting of cells using a microscope with 400x magnification. The results showed that seven genera of diatoms were found: Chaetoceros sp. with the highest of cells abundance (5.061 cells/L), successively followed by Nitzschia sp. (611 cells/L), Thalassionema sp. (569 cells/L), Skeletonema sp. (446 cells/L), Coscinodiscus sp. (176 cells/L), Navicula sp. (40 cells/L) and Amphora sp. (11 cells/L). At station I and II showed that the maximum abundance occurred at 6 am, and the minimum abundance occurred at 6 pm. At station III the maximum abundance occurred at midnight and a minimum abundance occurred at noon. Diatoms showed different daily fluctuations at different time and stations. The supporting diversity index value of medium, low uniformity, and no dominance factor causing the Gumilamo-Magaliho waters can be developed for aquaculture.Keywords: diatom, diatom abundance

Abstract

Pseudodiaptomus species are one of the copepods species as a superior live feed to date due to their nutrition and digestive enzyme contents. Some of them have been used as natural for rearing marine fish larvae. The purposes of this study were to compare the nutritional and protease activity between two species of Pseudodiaptomus originated from Indonesian waters, and to determine more superior species to cultivate. Two different feeds i.e. Thalassiosira sp. and milk powder were used to grow the Pseudodiaptomus species. Analysis of amino acids (AAs) and fatty acids (FAs) profiles were carried out for both the Pseudodiaptomus species samples and the feeds, while the protease activity assay was carried out only for the Pseudodiaptomus species samples. Results indicated that the nutritional and protease activity profiles of Pseudodiaptomus were affected by the types of feed. Pseudodiaptomus code P61 was more superior to Pseudodiaptomus code P71. This code P61 species contained a wide variety of essential fatty acids and exhibited stabile protease activity under the different feeding treatments. However, P61 contained a lower total AA content than P71. Both of them could be cultivated because they were complementary in nutrients to each other.
