Abstract

The learning process has a benchmark that refers to the achievements experienced by students, namely learning outcomes. Learning outcomes achieved by students have two influencing factors namely internal and external factors. These two factors that influence learning outcomes are interest and learning difficulties. The results of observations on the learning outcomes of students of SMPN 11 Padang in science are still low. Students say that science learning are numerous and difficult. The existence of students who score below the average and the lack of student interest shows the student's interest in learning in science is less and it can be assumed that students have difficulty learning science. Research is a descriptive study. Research uses a correlational study approach. Research subjects consisted of 30 people in class VIII G of SMP 11 Padang. To find out the relationship between variables expressed by the correlation coefficient, data analysis techniques are used using the Sperman Rank correlation. The correlation between student interest and learning outcomes is weak, that is -0.32, the contribution of 10.24% does not have a significant relationship. There is a significant relationship between learning difficulties and learning outcomes, medium criteria w ith a value of 0.59, contribution value is 34.81%. Correlation criteria for interests and difficulties with strong learning outcomes with a value of 0.66 and a contribution of 43.56%, as well as a significant relationship between variables. The results of the relationship between learning interest and learning difficulties with learning outcomes are strong and each variable has a significantly relationship.

Abstract

Chlorophyll is a pigment that gives a green color to the leaves and stems of a plant. Chlorophyll plays an important role in the process of photosynthesis, besides chlorophyll also contains high antioxidants, anti-inflammatory properties and is a wound healing agent. Chlorophyll is found in green vegetables, especially kale. The leaves and stems of kale contain lots of vitamins, protein, calcium, phosphorus, sitosterol and minerals, especially iron which are useful for the growth and health of the human body. Water spinach has many benefits in overcoming constipation, preventing anemia, preventing insomnia and other benefits. Water spinach can be grown hydroponically and non-hydroponically. The objectives of this study were: to determine the chlorophyll content of kale plants cultivated hydroponically and non-hydroponically. This research was conducted at the Wire House of the Biology Laboratory of Padang State University in January-March 2020. This research is a descriptive study. The analysis was carried out: chlorophyll content of kale. Hydroponic kale samples were obtained from the West Sumatra Hydroponic Community in Alai Padang, while the non-hydroponic samples were purchased at Pasar Raya Padang, the analysis of vitamin C content was carried out by the Spectrophotometric Method. From the research that has been done, it is found that the average content of chlorophyll content in hydroponic cultivated kale is 12.21 mg/L and non-hydroponic 12.34 mg/L. The conclusion of the research results is that the chlorophyll content of kale cultivated by hydroponics is lower than that of water spinach cultivated non-hydroponically.

Abstract

Abstract. Sauerkraut is cabbage that is produced from natural fermentation by bacteria in the presence of 2.5 percent salt. Salt additions limits the activity of gram –negative bacteria, while the growth of lactic acid bacteria will increase. Chili is a vegetable of the genus Capsicum which has high economic value and also contains various compounds that are useful for human health. One method to get good quality cayenne is fermentation. Fermentation is part of biotechnology that uses microorganisms as the main actors in a process. One of the microbes that determines the success of fermentation is lactic acid bacteria.                The purpose of this study is isolate LAB from Sauerkraut with the additional cayenne pepper the type of LAB produced microscopically. Research methods, the ingredients used are cabbage and cayenne  fermentation (sauerkraut with the additional cayenne pepper), MRSa, 0,9% NaCl, crystal violet paint from biological laboratories UNP. Isolation LAB from Sauerkraut done in with fermentation Sauerkraut and then plant the sauerkraut into the MRSa medium with streak plate methods. The isolates obtained were identified microscopically using a microscope with gram staining method.                From the research that has been done, the following result are obtained : Sauerkraut with additional cayenne pepper direcly into MRSa medium and gram staining, there were 12 colonies of gram positive bacteria with bacil cell form, and negative catalase test.  We can identify this colonies as Lactobacillius sp.

Abstract

Terasi is one of the fermented product of shrimp or fish which is often used as food seasoning by the people. Terasi is also a source of Lactic Acid Bacteria (LAB) which has the potential as a culture for probiotic starters. Probiotics are dietary supplements containing live microbes that profitable to their hosts. This study aimed to identify probiotic lactic acid bacteria isolated from terasi of shrimp based on the 16S ribosomal ribonucleic acid (rRNA) gene sequence. LAB isolation from terasi was done by pour plate method using selective medium, MRSA (Man Rogosa Sharpe Agar). The identification of LAB in this study used a method of molecular with a marker gene of 16S rRNA. A total of 3 isolates were obtained from the isolation process. All LAB isolates are rod (Basil) positive Gram bacteria, negative catalase. Two isolates (TR 1 and TR 2) were identified as Enterococcus faecalis. While one more isolate (TR 3) were identified as Weissella cibaria.

Abstract

Prebiotics are good coumpounds used in the growth of lactic acid bacteria (LAB) in digestion, prebiotics come from vegetables, fruits and seeds. Tomatoes are thought to be one of the natural media of bacteria because tomatoes contain various chemical compositions that are needed as a substrate for LAB. The purpose of this study is to isolate and determine the type of LAB produced microscopically. The ingredients used are tomatoes obtained from Padang Panjang market, with Merck NA media, oxoid MRSa, 0,9% NaCl, and crystal violet paint. Isolation LAB from tomatoes done in two ways, the first with plant tomato tissue directly into the NA medium and the second with fermentation tomato and then plant the tomato into the MRSa medium with streak plate methods. The isolates obtained were identified microscopically using a microscope with gram staining method. From the research that has been done, the following result are obtained : (1) Plant tomatoes tissue direcly into NA medium and gram staining, there were 1 colonies of gram positive bacteria with bacil cell form. (2). Fermentation tomatoes from the results, there were 2 colonies gram positive bacteria with bacil cell form. We can identify this colonies as Lactobacillius bulgaricus.
