Abstract

The use of organic fertilizers in Indonesia is increasing, this is due to the scarcity of synthetic fertilizers. Organic fertilizers have their own challenges in terms of the concentration they contain. In addition, some organic materials that exist today are very abundant, so it needs to be used as organic fertilizer, one of which is betel leaf. However, betel leaf itself is an additional ingredient that can increase the existing nutrient content. In this study, analysis of the macro elements in organic fertilizers was carried out by adding variations in the amount of betel leaf raw material. The research was conducted using variations of betel leaf extract 2%, 4%, and 6%. The test analysis in this study was in the form of N, P, and K levels. The results showed that the highest N content was in the 4% betel leaf variation, which was 0.1%, the highest P content was in the 2% variation, which was 0.04%, and the highest K content was at 2% variation, namely 0.066%. From these results, it can be said that there was no significant effect of the addition of betel leaf extract on the macro-nutrient content of liquid organic fertilizer.

Abstract

Illegal Gold Mining in several areas of West Nusa Tenggara, particularly in Sumbawa, has had negative impacts on the environment, such as natural damage and environmental pollution, including water contamination with mercury. This study aims to determine the effect of variations in absorbents from coconut shell, candlenut shell, and bidara wood on the physical and chemical characteristics of mining wastewater. The method used in this research is experimental, involving testing with filtration equipment. This study employs three treatments (absorbent variations) and three repetitions for each treatment. The results indicate that the use of activated carbon from coconut shell, candlenut shell, and bidara wood can affect the color, TDS, pH, and mercury content in mining wastewater. Among the three variations of activated carbon, the treatment with bidara wood activated carbon proved to be the most effective in clarifying water color with a score of 1.4 (very clear), reducing TDS by 3570 ppm, improving pH to 7.63, and decreasing mercury content in the water to 1.39 µg/L.
