Abstract

Background: The nervous system is composed of a complex structure to support its highly organized work. Damage to the working mechanism of nervous systems can exert fatal impacts to the human body. One of the consequences of damage to the mechanism of action potentials is grand mal epilepsy. The purpose of this paper is to determine the structure, function, and mechanism of action of neurons, establish grand mal epilepsy as a result of damage to the working mechanism of neurons, and recognize the ketogenic diet as a non-pharmacological therapy for epilepsy patients. Methods: The research method used is descriptive qualitative research. Results: Nerve cells generally consist of dendrites for receiving stimuli, cell bodies for transmitting stimuli to the axon, and axons for transmitting stimuli to other nerve cells. Grand mal epilepsy is a nervous system disorder caused by the increased activity of sending electrical waves throughout the brain that can reach up to four times faster than normal. However, grand mal epilepsy patients suffer from an excessive number of seizures that may occur at any time. Conclusions: The ketogenic diet method is a high-fat and low-carbohydrate diet method that can reduce electrical activity in the brain. Ketone-containing fats have a stabilizing effect on the central nervous system, contributing to anticonvulsant and antiepileptic effects that may reduce the excessive number of seizures experienced by patients. The application of this diet should be balanced with the provision of additional intake of multivitamins, minerals, and fiber to balance the nutrients the body needs.

Abstract

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.

Abstract

Background: Katokkon is a local red pepper that is widely cultivated in the North Toraja Regency and several surrounding areas within the scope of South Sulawesi Province, Indonesia. This pepper has a spicy taste and a unique fruit shape like paprika in small size and is rich in nutrients such as ascorbic acid, carotenoids, and capsaicin so that it benefits human health and serves as one of the commodities that improve the people's economy. Katokkon pepper is adapted to grow well in upland areas so that cultivation outside this habitat requires certain efforts to be optimal. Seed germination is an important step in plant cultivation. Coconut water and shallots extract were commonly used as sources of growth regulators substances to stimulate seed germination. Therefore, this study aims to determine the effect of natural growth regulators substances on the Katokkon pepper seed germination. Methods: This study was conducted by a factorial randomized block design with two factors and three replications. The Katokkon pepper seeds were soaked in the 25%, 50%, and 75% of coconut water and shallots solution for 24 hours. Results: The treatment of coconut water with a concentration of 75% (ZAK3) has a significant effect on the percentage and speed of seed germination of Katokkon pepper. Conclusions: The greater concentration of natural growth regulators used, the greater the percentage of seed germination obtained. However, the effect of coconut water treatment on seed germination of Katokkon pepper was more significant than the shallots extract.
