Abstract

The use of microwaves in the biodiesel production process has been widely used because it has many advantages, one of which is showing a more efficient reaction, with a short reaction time and separation process. It is necessary to determine the effect of microwaves on the quality of biodiesel from palm oil and soybean oil. The aim of the research was to: 1) Evaluate the effect of power on the yield of palm oil and soybean oil biodiesel with a mole ratio of 1:12, reaction time of 2.5 minutes, and NaOH catalyst concentration of 0.2%. 2) Evaluate the effect of power on the characteristics of palm oil and soybean oil biodiesel with a mole ratio of 1:12, reaction time of 2.5 minutes, and NaOH catalyst concentration of 0.2%. 3) Evaluate the effect of power on the quality of palm oil and soybean oil biodiesel methyl ester compounds with a mole ratio of 1:12, reaction time of 2.5 minutes, and NaOH catalyst concentration of 0.2%. This research was carried out by preparing samples of oil, methanol, catalyst and distilled water. Followed by weighing the 0.2% catalyst and dissolving it with methanol and oil with a mole ratio of 1:12 then reacting with a microwave method transesterification reaction with power variations of 100, 264, 400 watts and a reaction time of 2.5 minutes. The results of transesterification produce biodiesel and glycerol. Biodiesel is separated for the purification process. The results of biodiesel purification are followed by physical and chemical testing. The results of this research show that: (1) The yield of palm oil biodiesel was 96% with a power of 400 watts and the yield of soybean oil biodiesel was 92% with a power of 400 watts. (2) The characteristics show that they are in accordance with SNI 7812:2015, except for water content. (3) The optimal % area of methyl ester obtained from palm oil biodiesel is 55.23% of 400 watt power and 37.38% of 264 watt power from soybean oil biodiesel.

Abstract

The Bolaang Mongondow region, especially in Tanoyan Selatan Village within the Lolayan District, presents considerable promise for the extraction of economically significant minerals, including gold ore. In this region, the practice of small-scale gold mining frequently utilizes cyanidation methods, which present significant environmental hazards. This research endeavors to investigate the effectiveness of Lobong lime and Kemindo lime in neutralizing the pH of mining wastewater, with particular emphasis on the impact of lime type and concentration on pH levels. The methodology for treating wastewater entailed the incorporation of lime powder into mining wastewater at diverse concentrations of 0.03 g, 0.04 g, 0.05 g, 0.08 g, 0.10 g, and 0.12 g, accompanied by stirring intervals of 1 minute, 3 minutes, 5 minutes, 7 minutes, and 10 minutes. The results indicated that Kemindo lime consistently surpassed Lobong lime in elevating pH levels. Moreover, the level of lime demonstrated a direct positive relationship with the enhancement of pH; increased lime concentrations led to markedly higher pH values. The findings highlight the essential importance of choosing the correct type and concentration of lime in wastewater treatment to improve both water and soil quality, consequently reducing environmental repercussions.
