Liquid organic fertilizer is a type of fertilizer that has a liquid form with a brownish color and is commonly used in agriculture as a supporting material for the main fertilizer. Liquid organic fertilizer can be produced through the fermentation process of organic matter, such as plant residues, animal or human waste, and organic waste so that it will not damage the environment. The manufacture of liquid organic fertilizer in this study uses waste cooking oil as raw material which will be fermented anaerobically for 21 days with the use of EM4 activator volume of 10 mL and 50 mL. This study was conducted to determine how much potential used cooking oil waste can be converted into liquid organic fertilizer. The results showed that the best concentration of nitrogen, phosphorus, potassium, and carbon organic in liquid organic fertilizer was obtained at 10 mL volume of EM4 activator. The best nitrogen concentration is 0.520 ppm, the best phosphorus concentration is 12.213 ppm, the best potassium concentration is 12013.825 ppm, and the best organic carbon concentration is 2.10%.

Silver is a type of heavy metal that is a pollutant to the environment to a certain extent. Ag concentrations in photographic waste can reach 1,000–10,000 mg/L. If photographic waste is discharged into the environment without special treatment, it can cause serious problems. The working method of decreasing the silver ion content (Ag + ) in the liquid waste used for photographic washing using resin with ion exchange is by contacting the liquid waste and resin. The purpose of this study was to determine the effect of resin weight in the separation of Ag + ions. This Ag + ion separation study was carried out with a resin weight variable of 125gr; 150gr; 175gr; 200gr, and 225gr and a stirring speed of 100 rpm; 150 rpm; 200 rpm, 250 rpm; and 300 rpm. Based on the results of the study, the silver (Ag + ) content in the liquid waste from photographic washing was found to be 5.711 mg/L. The highest decrease in silver ion content (Ag + ) was in the resin weight of 225gr with a stirring speed of 300 rpm, with the remaining Ag + ion content in the liquid waste from photographic washing 0.012 mg/L. The remaining Ag+ ion content in photographic waste has met the quality standard of wastewater for disposal to the environment, which is 5 mg/L.

Tobacco stalks are classified as waste that has the potential to be used as raw material for crystal cellulose due to its high cellulose content. Nanocellulose is a natural fiber extracted from cellulose, having a diameter < 100 nm. This study aims to characterize cellulose crystal from tobacco stalks and to determine the best conditions for the synthesis of cellulose crystal based on bleaching time and sulfuric acid concentration. The cellulose crystal synthesis process is carried out in 3 series of processes: delignification , bleaching, and acid hydrolysis processes. The delignification process was carried out with 12% NaOH solution followed by the bleaching process with 2% H 2 O 2 solution with time variations of 1 hour, 1.5 hours ; 2 hours ; 2.5 hours ; 3 hours. Analysis of cellulose using the chesson datta method showed that the best conditions occurred at 1.5 hours of bleaching with 63.1554% cellulose. The acid hydrolysis process uses H 2 SO 4 solution with various concentrations of 20% ; 30% ; 40% ; 50% ; 60%. Characterization is done by FTIR and SEM analysis. Research shows that cellulose crystal hasn’t yet reached the nano size. The best concentration of sulfuric acid in reducing the size of cellulose is 40%.

Dust (PM10 and PM2.5) is a significant issue affecting public health globally. The impact of dust concentration particularly causing short-term respiratory system disorders. This study aims to measure dust concentration in Bandung Regency and assess its risks to public health. Dust concentration measurement was carried out for 3 time periods (morning, afternoon, and evening) in 3 sub-districts categorized by land use (agricultural, residential, and industrial). Public health data were obtained through questionnaire on perception of respiratory system disorders experienced by the community. The results of the measurement of dust concentration showed that the highest concentrations of dust were found in the industrial sector, followed by the agricultural and residential sectors. PM2.5 and PM10 concentrations in the industrial sector exceeded the quality standard, while in the agricultural and residential sectors were within the quality standard. Despite this, correlation analysis showed no significant relationship between dust concentration and respiratory system disorders. Comparative analysis indicated significant differences in dust concentrations between the different sectors. Prevalence ratio analysis indicated that the concentration of dust increased the likelihood of respiratory system disorders by 1.091 times, and HQ of 1.835 showed a possibility of adverse effects occurring due to the concentration of dust in the area. Keywords: dust, respiratory disorders, land use
