<![CDATA[Background: Kratom (Mitragyna speciosa Korth.) is widely used by the surrounding community as a traditional antidiabetic and antiobesity drug due to its high content of secondary metabolite compounds. The purpose of writing this review is to find out the bioinduction influence of Bacillus thuringiensis and Pseudomonas fluorescens and to find out the presence of an increase in secondary metabolites. Method: Writing and assessing source problems related to using literature study methods. Results: Kratom leaf methanol extract contains secondary metabolites of alkaloid groups, flavonoids, steroids/terpenoids, phenols and saponins. The main compound content of kratom leaves classified as alkaloids is mitragynine that has not been found in other plants. The administration of non-pathogenic bacteria such as Bacillus thuringiensis and Pseudomonas fluorescens can induce plant defenses and can accumulate the production of phenol compounds and flavonoids in plants. Conclusion: Based on the literature search results, kratom can indeed function as an antidiabetic and antiobesity and induction of microbes, namely Bacillus thuringiensis and Pseudomonas fluorescens bacteria can increase the content of secondary metabolites of plants. Through the increase in secondary metabolites, the efficacy of plants is higher to overcome health problems, namely antidiabetics and antiobesity.]]>

<![CDATA[Background: Obesity is an imbalance between height and weight due to excessive body fat tissue. The purpose of writing this review is to find out the effect of enzyme inhibitor induction on fat-rich foods as control of obesity. Method: Writing and assessing source problems related to using literature study methods. Results: One way of controlling obesity is by regulating dietary patterns and consumption of lipase inhibitors. Inhibition of lipase is one of the most widely developed effective ways in diet medicine. Inhibitory compounds cause pancreatic lipase to lose its ability in decomposition that enters the blood. The potency of plant-origin lipase inhibitor compounds can be increased in both number and performance. Increasing the production of secondary metabolite group inhibitors is by fermentation of microorganisms. Conclusion: Inhibition of triglyceride hydrolysis through inhibition of lipase enzymes can decrease and prevent obesity. Secondary metabolite induction can be fermented with microorganisms. The production of secondary metabolite compounds in medicinal plants can be increased in the presence of fermentation. Flavonoids can decrease the accumulation of lipids in the heart, reduce glucose absorption, inhibit the breakdown of polysaccharides into monosaccharides.]]>

<![CDATA[Background: Hydroponics is a method of agriculture that utilizes water as a planting medium. The purpose of the study was to find out good working procedures and nutrient solution formulas capable of showing symptoms of morphological nutritional deficiencies in plants. Methods: The plants used are the seeds of kale plants that are sown within 1 - 2 weeks (until roots, stems, and leaves grow). The design used is Random Group using three formulas with nine kinds of treatment on each formula and three repeats. Experiments were conducted on two hydroponic systems, the axis and without the axis. The parameters observed are the number of leaves, the leaves' length, the leaves' width, the plant's height, and the plant's height. Results: Observational data in the analysis using SPSS 25. The effect of treatment with test parameters is seen using ANOVA analysis and BNT advanced tests. Visual observations showed the formula of nutrient solutions 1, 2 and 3 using both the axis system and without the axis showed symptoms of nutritional deficiencies in kale plants. The axis less system experiment gave more significant results on all parameters except PD (leaf length) than the axis system based on the average results of BNT advanced tests. Conclusion: Nutrient solutions 1, 2 and 3 have a real effect on all test parameters.]]>
