Indonesia has recently been hit by the international Covid 19 outbreak. In most parts of Indonesia, it has an impact on all activities. The majority of the teaching and research is carried out at home. The concept of forcing activities at home by providing the opportunity to conduct research in the drying process. It's an example of how students might use the drying process at home. The notion of drying the cucumber as a material sample was implemented and the drying kinetics were influenced by the size or form of the sample, the operation time, and the temperature. The information that affects the rate of drying is provided by the results of drying in an open area naturally and in a room. In comparison to temperature and operation duration, the start weight was the most affected. The time needed 4 to 8 days to dry.

Adsorption is one of the processes used to purify used cooking oil by using adsorbents from natural and carbonized corn cob as part of sustainability. The adsorption process is chosen because it is more economical, efficient, relatively affordable cost, and can be regenerated. This study was conducted in batches to observe changes in the quality of used cooking oil at certain time intervals and to determine the modeling of adsorption kinetics on natural corn cob and carbonized corn cob adsorbents. The sample of this study is 100 ml of used cooking oil with adsorbents in the form of natural corn cob and carbonized corn cob with a mass of 3 grams and a particle size of 70 mesh. This study's best adsorption result is corn cob carbon adsorbent. This can be seen from the final turbidity value of 37.3 NTU compared to the natural corn cob adsorbent of 37.6 NTU.

The statistics center in 2021 stated that North Sumatra is the second largest palm oil-producing province in Indonesia with a plantation area of 1,373.30 Ha. The use of cooking oil in Indonesia in 2021 was 18.4 million tons and increased by 6% from the previous year. This research utilizes palm fronds for the manufacture of adsorbents in cooking oil refining. The method used is carbonization with the help of pyrolysis. The carbon is chopped into powder and divided by variations of 1.5, 3, and 4.5 grams. Each gram is stirred using a shaker with speed variations of 50, 70, and 100 rpm. Turbidity is tested using a turbidimeter once every 20 minutes for 180 minutes. The results of the analysis showed that the best adsorbent weight in reducing used cooking oil was 4.5 grams with a turbidity level of 15.5 NTU and stirring of 100 rpm.

This study examines the operating pressure effect on the manufacture of biodiesel from Palm Kernel Fatty Acid Distillate (PKFAD) by using para-Toluene Sulfonic Acid (PTSA) catalyst. The operating pressures studied are the vacuum pressures of 70 kPa, 80 kPa, 90 kPa, and 100 kPa, which varied with PTSA concentrations of 5%, 10%, 15%, 20%, and 25%, and the molar ratios of methanol and PKFAD are 5: 1, 6: 1, 7: 1, 8: 1, 9: 1, and 10: 1. Biodiesel production from PKFAD was carried out with reaction duration of 120 minutes and reaction temperature at 50 0 C. The amounts of fatty acids converted to biodiesel were calculated based on the initial and acid numbers after the esterification reaction. The results show that a vacuum pressure of 70 kPa to 100 kPa provides a conversion above 96% for all catalyst concentrations and all methanol and PKFAD molar ratios. The highest conversion of PKFAD to biodiesel of 98.6% is obtained at an operating pressure of 80 kPa, a catalyst concentration of 25%, and the molar ratio of methanol and PKFAD is 10: 1. The biodiesel characteristics obtained in this study have met the standards of the American Society for Testing Materials.

Indonesia is the second largest producer of palm oil in the world today after Malaysia. Since 2003, the amount of palm oil production in Indonesia has reached approximately 9.9 million tons per year. According to (BPS 2021), the area of oil palm land in North Sumatra reached 442 072.76 hectares. This research will purify used cooking oil using natural adsorbents by utilizing palm frond waste. Palm fronds are chopped into powder, then sifted with sizes of 50, 70 and 100 mesh after which they are weighed with weights of 1.5, 3 and 4.5 grams. Oil palm frond adsorbents with mass variations of 4.5 grams have the greatest adsorption power in reducing used cooking oil and the best adsorption kinetics based on the correlation coefficient is the pseudo second order equation.

Anticorrosive paints consist of formulations with added organic corrosion inhibitors that aim to improve the protection of metal surfaces from corrosion attack. Currently, organic-based corrosion inhibitors are more used in industrial parts, because organic inhibitors are cheap and environmentally friendly than inorganic inhibitors. This study aims to analyze the use of powder, concentrated extract and alkaloids from soursop leaves in paint on determining the corrosion rate and corrosion inhibition efficiency of iron plate in NaCl media. Soursop leaves contain alkaloid compounds that can act as corrosion inhibitors. Alkaloids have N H and O-H functional groups. The form of inhibitors added to the paint is powder, extracts and alkaloids from soursop leaves with concentrations of 2%, 4%, 6% and 8% and immersion time in 50 mL 3% NaCl media for 2 days, 4 days, 6 days and 8 days. The method used in determining the corrosion rate is the weight reduction method. Based on the results obtained, the lowest corrosion rate of iron plate on immersion in 3% NaCl medium for 8 days amounted to 2.77 mpy.

The remediation operation approach was used, such as batch, flushing column without foam, and with foam of SDS solution. Increasing the SDS concentration is possible to improve the removal ability of Cd ions from the sand surface. For batch, the operation performs the higher removal ability by increasing the shaking rotation per minute (rpm). Fluctuation of the percentage removal efficiency (% RE) was shown by using a flushing column without foam at each flow rate variation. The channeling effect during flushing in the column was proved to be the cause of fluctuation in the removal efficiency. Flushing with foam is possible to increase the removal efficiency from 10% by batch and flushing without foam to about 70% with foam.
