Abstract

The production and growth of Oryza sativa L. rice plants are crucial for maintaining the long-term viability of food agriculture. The purpose of this study was to assess how liquid organic fertilizer affected the growth of the rice cultivars Kusuma 06 and Inpari 30. The study was carried out in Pape Village, which is situated in Bajawa Sub-district, Ngada Regency, East Nusa Tenggara Province, from January to April of 2024. The research method involved the application of liquid organic fertiliser to Inpari 30 and Kusuma 06 rice plants in the field during the research period. The height, number of leaves, and number of tillers on rice plants were noted, as well as the infestation rate of false whiteflies and brown stem leafhoppers. The results demonstrated that liquid organic fertiliser exerted a significant influence on rice plant growth, with enhanced plant height, leaf number, and tiller number observed in plants treated with liquid organic fertiliser. Furthermore, the infestation of false white pests and brown stem leafhoppers also exerted a notable impact on the growth and yield of rice plants, resulting in a reduction in grain production and substantial economic losses. The results of research conducted in Pape Village, Bajawa District, Ngada Regency indicated that the Inpari 30 rice variety yielded 9 sacks, while the Kusuma 06 variety yielded 7 sacks. The productivity of the Inpari 30 rice variety was found to be superior, particularly among wetland rice farmers. Consequently, the application of liquid organic fertiliser and integrated pest control is crucial to the practice of paddy rice farming in order to achieve optimal yields.

Abstract

The fungus Colletotrichum acutatum which often attacks chili plants causes anthracnose disease. Farmers generally use fungicides to control this disease. Continuous use of synthetic fungicides will have negative impacts. Plant extracts as an alternative to natural fungicides can be an appropriate and environmentally friendly choice. One of them is the use of Local Microorganisms (MOL). This  research aims to determine the optimal concentration of coconut pulp MOL in increasing the resistance of red chilli plants to the fungus Colletotrichum acutatum that causes anthracnose disease. The study used a Totally Randomized Design (CRD) with 6 drugs, namely A (0 ml/water), B (5 ml/water), C (10 ml/water), D (15 ml/water), E (20 ml/water). ml/water), F (25 ml/water). There are four treatments each time. Information was broken down using ANOVA and continued with the Fair Genuine Contrast (BNJ) test at the 5% level (α = 5%). with a level of 5% (α = 5%). The results showed a significant effect on fungal colony diameter, germination period, plant height, plant incubation period, and disease severity. The best concentration of local coconut pulp microorganisms in inhibiting anthracnose disease was 25 ml/l water.

Abstract

The prevalence of hair loss in Indonesia is quite high at 64.7%. One of the cosmetic products used by the public to overcome the problem of hair loss is hair tonic. Hair tonic with synthetic content such as minoxidil can cause side effects including skin allergies and edema, so an alternative from natural ingredients is needed. There are various kinds of plants that are formulated in the form of hair tonic preparations to stimulate hair growth. The purpose of this paper is to ascertain how test animal hair growth activity is affected by the concentration of different types of extracts that have been prepared as hair tonic preparations. In order to complete the writing process, a literature review is conducted by searching online journals from the Google Scholar platform using a variety of relevant keywords as well as from other scientific literature that has been published during the last ten years. The results of the literature review indicate that, for the majority of plants, the formula's highest concentration of plant extracts exhibits the best hair growth activity in test animals.

Abstract

The Indonesian textile industry is developing to meet people's needs for clothing. 3916 industries in Indonesia exist in 2021, but the number of these industries is not balanced with liquid waste processing. One alternative way to reduce heavy metal levels in waste is bioremediation. The aim of this research is to determine how incubation time and the number of Pseudomonas aeruginosa and Bacillus subtlis bacteria influence the reduction of Pb metal levels in textile waste. Several steps include the bioremediation process, colony counting, measuring Pb metal levels, measuring temperature levels, measuring pH, and data analysis. Bioremediation results: Pseudomonas aeruginosa and Bacillus subtilis bacteria succeeded in reducing Pb metal levels in textile waste with an incubation time of 14 days. The results show that this bacterium is able to reduce Pb metal levels in textile waste with the addition of a 1:1 concentration of 56%, a 1:2 concentration of 86%, and a 2:1 concentration of 92. These results show that this bacterium is successful as a bioremediation agent in reducing Pb metal levels in waste.
