Abstract

Cherry tomatoes are a type of Red Dragon Fruit that has various benefits, including lowering cholesterol levels, preventing colon cancer, and strengthening the working power of muscles. Isolation of LAB isolated from Dragon Fruit as a production material for EPS. This study aims to isolate and identify LAB as a producer of EPS from red dragon fruit (Hylocereus polyrhiruz), which can produce exopolysaccharides. This research uses a descriptive research method. Data from experimental research in the laboratory obtained 10 LAB isolates, namely isolates NG1, NG2, NG3, NG4, NG5, NG6, NG7, NG8, NG9 and NG10. Based on the identification results, isolate NG1 has similarities with the genus Lactococcus (spherical, gram-positive, nonmotile, non-spore). While isolates NG2, NG3, NG4, NG5, NG6, NG7, NG8, NG9 and NG10 have similarities with the genus Lactobacillus (rod form, nonmotile, gram-positive). Based on the morphological characteristics, which are gram-positive, catalase-negative and non-spore. The ten isolates of lactic acid bacteria are capable of producing EPS. these are the results of EPS acquisition, namely: NG1(152.1 mg/L), NG2(127.9 mg/L), NG3(134.6 mg/L), NG4(130.9 mg/L), NG5(137 mg/L), NG6(139.2 mg/L), NG7(204.9 mg/L), NG8(156.2 mg/L), NG9(136.4 mg/L), and NG10 (157, 3 mg/L). The highest amount of EPS was isolated NG7 at 204.9 mg/L. Meanwhile, the lowest EPS was isolated NG4 at 130.9 mg/L.

Abstract

Kolongan Village is one of the villages in Talawaan district of North Minahasa, North Sulawesi. In the village of Kolongan, some springs are potentially a clean water source for the people of the village. This research aims to analyze the quality of the springs in the village of Kolongan Talawaan, Prefectures as a water source. This type of research is quantitative, and the method used in this research is the Indonesian National Standard (SNI) according to the water quality parameters that have been established with the direct observation plan of the physical properties of water and with the laboratory testing plan for the observation of water chemical and biological properties with indicators of iron, sensitivity, manganese, E.coli, taste, and smell. The research was conducted from July 24, 2021, to September 20, 2021. The water quality measurement results in the spring in one village of Kolongan showed iron <0.0086 mg/L, iron 69-93 mg/ L, manganese 0.03-0.07 mg / L, E. coli, 11 CFU, not sensitive and odorless. Water source 2 showed iron <0.086 mg / l, density 75-85 mg/ l, manganese 0.02-0.03 mg/l, and E. coli, 3.6-9.2 CFU, is not sensible and odorless. The pollution index calculation indicates that the springs in Kolongan Village belong well. However, because they still contain biological reservoirs, it is necessary to have an advanced process for them to be consumed by the community.

Abstract

The application of the conversion results from Eco-Enzyme into dishwashing soap, the fermentation process lasts for one months, where the resulting liquid is dark brown in color and has a very strong sweet and sour fermented aroma. There is a lack of public knowledge about the very profitable benefits of Eco-Enzyme, such as as a multi-purpose cleaner as a multi-functional liquid which can be converted, one of the ways, into dishwashing soap. This research aims to determine the application of the results of converting Eco-Enzyme into dishwashing soap. This research used experimental methods and a research period of 3 months. This Eco-Enzyme is made with a ratio of organic ingredients: sugar: water 3:1:10. The Eco-Enzyme harvest is converted into dishwashing soap by adding lerak and Methyl Ester Sulfonate (MES). Eco-Enzyme conversion soap was then applied to several treatment groups: plastic plates, cans and glass. The results of the application show that the dishes washed with Eco-Enzyme using lerak have not completely removed dirt, oil and odors in each treatment, whereas Eco-Enzyme using Methyl Ester Sulfonate (MES) when compared with Sunlight brand liquid soap sold on the market shows that there are similarities both in terms of cleanliness, tapestry and smell. The research conclusion is that the application of the Eco-Enzyme conversion results has significant potential to be developed into an active ingredient for environmentally friendly dishwashing soap.

Abstract

The lack of scientific information about the current condition of the mangrove ecosystem on the Molas beach in the Bunaken District of Manado City is an important reason to conduct a study related to the analysis of mangrove forest vegetation. The purpose of this research is to identify the types of mangroves and to find the Important Value Index (INP) of mangroves on the Molas beach in the Bunaken District of Manado City. Data collection was conducted using the line transect method with plots at only one observation station, which was then analyzed to determine the Importance Value Index (INP). Based on the observations, it was found that four types of mangroves were present at the research location. The dominant mangrove species are Bruguiera Cylindrica, Bruguiera gymnorrhiza, Aegiceras cosniculatum, and Ceriops tagal. The substrate condition, which is dominated by muddy sand, and the water quality parameters that affect mangrove growth generally still meet the standards for mangrove growth. The species Ceriops tagal has the highest values of Relative Density, Relative Frequency, and Relative Dominance, resulting in the highest INP. Meanwhile, the lowest INP was found in the species Bruguiera gymnorrhiza in the tree category

Abstract

Chicken meat (Gallus gallus domesticus) plays an important role in society with its role as one of the sources of fulfillment of animal protein in Indonesia. With the high consumption of chicken meat by the public, the hygiene and safety of chicken meat must be ensured so as not to incur losses to the people. This study aimed to determine the bacterial contamination based on the testing of Total Plate Counts, Coliform, Escherichia coli, and Salmonella sp. Meet the requirement of the Indonesian National Standard on chicken meat in the traditional market of Langowan Selatan District. The method used in this research is a descriptive method to analyze and describe the results of the study, the testing using several indicators to directly conclude bacterial contamination. The results of the total plate count bacterial contamination test of the colonies, TPC in sample 1 = 29,1x kol/, sample 2 = 29,4x kol/, sample 3 = 27,7x kol/. MPN of Coliform and Escherichia coli results obtained in samples S1, S2, and S3 are 11x kol/gr. The results of microbact Salmonella sp. In samples S1 are positive, and S2 and S3 are negative. Based on observations, it is suspected that contamination occurs because sellers use equipment that is less sterile and there is no cover or barrier so the chicken meat is in direct contact with the air and customer. It is concluded that based on bacterial testing indicators, chicken meat in the traditional market of Langowan Selatan District has exceeded the limit of SNI 7388 2009 and is contaminated.
