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.

Abstract

This research aims to design and build an alcohol distillation machine made from duku fruit using a refrigerator cooling system and a box cooler as a condenser. The distillation machine utilizes a heating furnace to produce ethanol vapor from fermentation, which is then condensed in a cooled box cooler. Tests were conducted with variations in furnace temperature (110°C, 125°C, 140°C, and 155°C). The results show that the higher the heating temperature, the volume of distillate produced increases, from ±132 ml to ±330 ml. However, the ethanol content remained relatively low (10-20%) due to the low initial ethanol content of the fermentation and only one-stage distillation. These results show that the design of the device can function well on a laboratory scale, although further distillation is needed to increase the ethanol content. This research is expected to be the first step in developing a small-scale ethanol distillation device that is efficient and easy to implement.

Abstract

The study aimed to obtain the interaction of NPK and ecoenzymes on the growth and yield of soybean plants, thus reducing the use of NPK.  The experiment was conducted on dry land in Kuranji-Padang, at an altitude of 10 m above sea level, from May to August 2023.  The study used a factorial completely randomized design (CRD) (4 x 3) with 3 replications.  The first factor was ecoenzyme consisting of 3 levels; 0, 5, 10, and 15 ml/l water.  The second factor is NPK which consists of 3 levels, namely; 100, 200, and 250 kg/ha.  Parameters observed; plant height, number of primary branches, number of leaves, number of effective root nodules, number of pods per plant, number of empty pods, pod length, 100 seed weight, and dry weight of seeds/plot.  Data were investigated for variance, if the effect was significant, it was followed by the 5% level of Honest Real Difference (BNJ) test.  Data were analyzed using Statistix software ver. 8. The results showed a significant interaction between NPK 200 kg/ha with 0 ml/l ecoenzyme on the growth of soybean plant height. NPK at 200 kg/ha significantly affected the number of primary branches, the number of pods, and the dry weight of seeds/plot. Ecoenzyme was not significant on the number of primary branches, number of leaves, number of root nodules, or pod length of soybean plants.  Optimization of ecoenzymes needs to be done by reducing the rate of NPK fertilizer given.

Abstract

Natural resources in Indonesia are abundant, but some are not utilized properly, resulting in environmental pollution waste, such as kapok fruit husk and jatropha fruit. This waste can be innovatively processed into briquettes. This study aims to analyze the characteristics of briquettes made from kapok fruit husk and jatropha fruit using starch adhesive. An experimental method was used with variations in raw material composition: P1=(KK 45:BJ 45:PR 10), P2=(KK 60:BJ 30:PR 10), and P3=(KK 90:PR 10). The research design applied a Completely Randomized Design (CRD) to analyze significant data at a 0.05% level. The results showed that the lowest average moisture content was at P2 with a value of 1.69%, the lowest ash content was at P2 with a value of 9.10%, the lowest volatile matter content was at P3 with a value of 84.46%, the highest fixed carbon content was at P2 with a value of 4.80%, and the highest calorific value was at P3 with a value of 9,478%. The characteristics that meet the Indonesian National Standard (SNI No.1683-2021) are only moisture content and calorific value, with the standard requiring moisture content <8-10% and calorific value >6,000. These results indicate that briquettes can serve as an environmentally friendly alternative fuel with potential for further development.
