MANFAAT EKOENZIM DARI LIMBAH ORGANIK RUMAH TANGGA SEBAGAI PENGAWET BUAH TOMAT CHERRY
Cherry tomato is a popular horticulture plant in the world and in Indonesia. Tomato plants (Lycopersicon esculentum) are included in the Solanaceae family. In Indonesia the level of consumption of tomatoes is increasing every year. With a higher selling price (IDR 20,000-IDR 30,000) compared to other tomatoes, the production of tomatoes has increased. Today, in addition to domestic needs, tomatoes have also been exported, but it is not uncommon for tomatoes to have been damaged or decreased in quality before they reach the user. Therefore it is necessary to develop fresh handling technology to prevent spoilage. In general, the preservation of fruit is used synthetic ingredients that are harmful to health. Therefore natural preservatives are needed as a substitute for preservatives of this synthesis to be safer. One natural ingredient for preserving cherry tomatoes is to use ecoenzymes from household organic waste in the form of vegetable and fruit skin wastes. So that the purpose of this study is to provide information on the effectiveness of the ecoenzymes of vegetable waste and fruit peels that can be used for cherry tomato preservation seen from the percentage of the production volume of ecoenzymes, the effect of the ecoenzyme concentration on the scale of cherry tomato preservation quality, and the effect of the ecoenzymes on the decay rate of cherry tomatoes . To simplify the coating of cherry tomatoes with liquid ecoenzymes, researchers took one way, namely using a coating application in the form of spraying (spraying). From the results of the study showed that the effective ecoenzymes to be used as preservatives of cherry tomatoes in terms of the effectiveness of the production of levels ofecoenzymes and the effectiveness of ecoenzymes on fruit preserving is on the variable I ecoenzymes with basic ingredients of household organic waste in the form of spinach.

PERBANDINGAN UJI ORGANOLEPTIK PADA DELAPAN VARIABEL PRODUK EKOENZIM
The problem of waste in Indonesia is a problem that has not been resolved until now. The composition of waste generated from human activities is 60-70% organic waste and the rest is non-organic waste. One way to manage organic waste is to use organic waste as the basis for making ecoenzymes. The making of these ecoenzymes is made by mixing organic waste used as raw material with palm sugar and water. Then the fermentation process is carried out for three months. Then after the harvest period, organoleptic testing is carried out. In general, this study aims to determine the comparison of organoleptic test results on eight variables of ecoenzyme products. There are three parameters that researchers observed including, color, odor and moisture content produced at harvest time. This research method uses the experimental method. In this study, the results show that in the color organoleptic test, there are striking differences, namely the first variable produces clear brown color and the fourth variable produces a turbid yellowish brown color. In aroma testing, on average all ecoenzyme products at harvest produce a characteristic acidic odor. Whereas in testing the water content, the highest water content produced is 100% or as much as 500 ml and the lowest water content is produced that is 72% or as much as 360 ml. The difference in the results of the water content obtained during the harvest is due to differences in the composition of the basic ingredients used so that the water content in these materials is different.

The study was conducted with the aim of knowing the lactose and protein content in formula milk aged 6-12 months and breastmilk (ASI) aged 6-12 months. The research method used in this research is analytical research method. The research was conducted in the nutrition laboratory of the Muhammadiyah University of Semarang. This study used breast milk samples for babies aged 6-12 months, namely 8 months and formula milk for babies aged 6-12 months which were found in supermarkets. Based on the data obtained, the lactose and protein content in formula milk used as the sample is higher than the lactose and protein content in breast milk. The results of the research obtained on the lactose content test in formula milk were 20.02% while in breast milk it was 13.85%, and on the test the protein content in formula milk was obtained at 8.44% while the protein test in breast milk obtained results of 1.92 %. The high and low levels of lactose and protein content in breast milk can also be caused by many factors, including economic factors and the education of breastfeeding mothers in the breast milk sample used. In economic factors, breastfeeding mothers in the breast milk sample used are mothers who have a lower middle economic level. Economic factors also affect the content of breast milk produced. In the education factor, the mother's baby is a high school graduate (SMA), in this case it certainly affects the breast milk content used in the research sample, especially in terms of knowledge. keywords: lactose, protein, breast milk, formula milk
Analisis Efektifitas Penggunaan Eco-enzyme pada Pengawetan Buah Stroberi dan Tomat dengan Perbandingan Konsentrasi
Eco-enzyme or commonly known as environmentally friendly enzymes are liquid fermented natural ingredients that are brown with a pungent fruit aroma. This enzyme contains propionic acid which can be used by microorganisms so that it can be used as a natural preservative. It is said to be eco-enzyme because it is made from residues or household waste such as vegetable or fruit waste which is mostly released by the community. The purpose of this research is to study today that a number of strawberries and tomatoes sprayed with eco-enzyme fluids increase the deterioration of quality which deals with sour aroma, soft texture and dents, as well as the growth of microorganisms in the outer layer of fruits with fruit that not sprayed with eco-enzyme fluids. This type of research is an experimental with 2 types of concentrations of eco-enzyme fluids, namely concentrations of 100% and 50% with controls using fruits that are not sprayed with ecoenzyme fluids. There are four eco-enzyme variables used in this study, namely, pineapple and mango skin (variable1), pineapple and yam peel (variable 2), watermelon, melons and pineapple skin (variable 3), and kale (variable 4). Based on the research, the results obtained in the liquid eco-enzyme both 100% concentration and 50% concentration are effective for preserving tomato fruit, but not so effective for preserving strawberries. This fruit occurs because the water content in tomatoes is less when compared to the air content in strawberries when viewed based on the surface area of the fruit.
