Abstract

Nickel slag is a product that is formed at high temperatures to form metal alloys that are stable enough. It becomes a challenge for researchers to find methods for extracting valuable metal content.  Leaching is one of the solid-liquid extraction methods that can be applied to separate important elements from a solid material.  By using strong acid solvents. Leaching of ferrous metal (Fe) as the main metal in nickel slags was carried out with a 98% 2M sulfuric acid extracting solution.  Destruction of the leachate of nickel slag was then conducted to simplify the complex elements in the samples so that they could be easily analyzed. Destruction of nickel slag leachate samples was carried out using a destructive solution in the form of nitric acid. The maximum yield of iron content was obtained at a size of 140 mesh and 60 minutes with an iron content of 19,141 ppm. The minimum yield of iron content was obtained at 80 mesh-30 minutes of leaching with an iron content of 18,433 ppm. The maximum recovery results were obtained at 140 mesh-60 minutes of leaching. Factors that can influence include solid sample size, extracting solution, mineral form in solids, complexity, pH, operating temperature, and leaching time.

Abstract

Coconut (Cocos nucifera L.) is one of Indonesia's agricultural products with potential. The most valuable coconut product is coconut oil, which can be obtained from the flesh of fresh coconuts or from copra. Virgin Coconut Oil (VCO) or pure coconut oil is the result of processing from the coconut plant in the form of a clear liquid with a distinctive coconut smell and has a long shelf life. Pure coconut oil or VCO has many benefits for body health, such as natural antibacterial, antiviral, anti-fungal and anti-protozoal properties. This study aims to compare the effect of tempe yeast, bread yeast, tape yeast, and without yeast on variations in the ratio of grated coconut and water (1: 1; 1:1,5; 1:2), on the amount of VCO produced. The experiment was carried out again and then the average volume of VCO produced by each yeast was taken. The average VCO results obtained ratio 1:1 were 209.5 ml for adding bread yeast, 153.5 ml for not using yeast, and 150.5 ml for adding tempeh yeast. Meanwhile, adding tape yeast produce the smallest yield 89 ml . Based on the ratio of grated coconut and water (1 kg: 1 liter) the optimum yield is 1:1. While the minimum yield is 1:1,5 ratio. The most VCO obtained is by adding baker's yeast to thick coconut milk in the second fermentation process. The order of highest yield based on the addition of yeast is bread yeast, tempeh yeast, and tape yeast. The yield of VCO yeast tempeh was slightly better than the yield without adding yeast. The organoleptic results and some of the VCO test results based on SNI 7783-2008 have fulfilled the specified requirements.

Abstract

Increasing urbanization and industrialization have led to serious heavy metal pollution problems, detrimental to the environment and human health. Phytoremediation, which utilizes hyperaccumulator plants such as Indian mustard and water hyacinth, presents an efficient and sustainable alternative. Despite having the advantages of low cost and utilization of renewable natural resources, phytoremediation also carries risks, such as contamination of consumable plant parts and limited efficiency. Therefore, selecting the right hyperaccumulator plants and having an in-depth understanding of phytoremediation mechanisms are the keys to increasing their success. Phytoremediation mechanisms, such as phytoextraction, hemofiltration, and phytostabilization, can be implemented by considering environmental conditions and contaminants. Factors such as the nature of the medium, root zone, and environmental conditions play a crucial role in determining the effectiveness of phytoremediation. Although challenges still exist, phytoremediation remains a promising approach to treating heavy metal pollution in an economical and environmentally friendly manner.

Abstract

Desalination technology, which has been the most widely utilized method of meeting the requirement for clean water for the past 50 years, can be employed in attempts to use seawater. The purpose of this study is to ascertain how variations in the composition of distilled water are affected by the multistage distillation of seawater from Cemara Sewu Beach, Bantul, Yogyakarta. LPG gas is used as fuel to heat sea water during the distillation process. To obtain distilled water, the seawater vapor is then condensed. Subsequently, the distillation procedure is executed in three phases, with every phase being evaluated using the distilled water. The overall CaCO3 hardness level in the first stage of distilled water is still high, thus it does not exceed clean water quality criteria. Meanwhile, in the second and third stages, there are two parameters, namely pH and total hardness level, which do not meet the clean water requirements. In general, the first stage of distilled water is sufficient to be processed into clean water with the addition of water hardness treatment. Repeated distillation has a tendency to reduce pH, total hardness, TDS, fluoride, nitrate and detergent.

Abstract

Proper hair maintenance is a crucial component of one's daily beauty regimen. Shampoo, a commonly utilized hair care solution, has a chemical blend that effectively eliminates filth while also offering moisturization and safeguarding. The objective of this study is to create shampoo formulations and preparations with chamomile extract. The chamomile flower extract contains active chemicals, specifically 1,3,4-trihydroxyflavones called apigenin and apigenin 7-o-glucoside. These compounds have several beneficial effects such as enhancing hair brightness and shine, as well as possessing antibacterial, antifungal, hypoglycemic, and antioxidant qualities. Shampoo's chemical composition is determined by analyzing factors such as pH, foamability, homogeneity, total plate count, yeast mold count, and other similar parameters. Upon examination of these criteria, it is evident that the formulation and shampoo formulations successfully complied with the test requirements outlined in SNI 06-2692-1992.
