ABSTRACT Crocodylus porosus is a protected species because of its high economic value. This research uses the method using a quantitative method with questionnaires, observation, and documentation. Data is analyzed on the likert scale. The research results show that community perception of Estuarine Crocodiles is high with a percentage of (43.23%) or 37 KK, and the level of community cons…
ABSTRACT This study aims to determine the components of genetic diversity, herritability, and genetic correlation between components of corn crop yields so that it can determine which characters can be used as alternative selection criteria. This research was carried out experimentally using a random group design with genotypes consisting of 12 genotypes. Each genotype was repeated 3 times…
ABSTRACT Acid soils generally have high hydrogen ions and cause the soil to react acidically. One of the impacts that arise as a result of acid pH is the low P available to plants. Increasing the efficiency of available phosphate can be done by utilizing phosphate solubilizing microorganisms. Phosphate solubilizing bacteria also play a role in dissolving insoluble phosphate into soluble, b…
ABSTRACT Rice plants (Oryza sativa L.) are very important food crops. Rice productivity needs to be increased in order to maximize production by improving the quality of rice seeds. One effort that can be made to improve the quality of rice seeds is to utilize bacteria containing the hormone indole acetic acid (IAA). The ability of IAA to stimulate cell elongation modifies certain physiolo…
Water pollution has a negative impact on quality of life, health, and the environment. One of the major sources of water pollution is synthetic dyes that are not properly treated. The textile industry contributes more than 55% of global dye wastewater. It uses over 80,000 metric tons of reactive dyes annually, and this number continues to rise. One of the hazardous dyes that is difficult to deg…

This final project presents the development of a new numerical method called the New Bracketing Iteration Method (MIBB) for solving single-variable nonlinear equations. MIBB is a modification of the regula-falsi method, incorporating a combination of the bracketing approach and adaptive linear interpolation. The main advantages of this method are its derivative-free nature and guaranteed global…
This final project discusses a new family of optimal fourth-order iterative me- thod to solve a nonlinear equation. This method is obtained by modifying Newtons method using a weight function. Analytically using the Taylor expan- sion and geometric series that the iterative method has a convergence order of four and efficiency index is 1.587. Computational tests show that the new me- thods in t…
Depression is a mental health disorder that often occurs in society, which is characterized by unstable mood swings. Synthetic antidepressants are quite widely available, these antidepressant drugs have side effects so that alternative antidepressant drugs from herbal plants are needed which have fewer side effects.
