Abstract
Tofu waste is a byproduct of tofu processing that cannot be just thrown away as it can pollute the waters. In this study, a laboratory-scale test was carried out on tofu waste produced from tofu factories in the Cirebon area. In this tofu waste treatment, activated sludge was used where the waste water was put into an anaerobic reactor with various incubation times. The reduction of COD (Chemical Oxygen Demand) for tofu wastewater treatment was carried out using the K2Cr2O7 oxidizer and anaerobic reactor with an insulated reactor. Afterwards, the anaerobic effluent was collected into the aerobic reactor using broken bricks. Experiment variations were carried out in anaerobic reactors, namely: sludge variation (1/2 and 1/3) and residence time variations, namely: 2 days, 4 days and 6 days. Measurements were taken at 3 points, namely: influent, anaerobic effluent and aerobic effluent. Based on the research, the highest decrease in anaerobic efficiency was 68.8% in the condition of ½ sludge volume and 2 days residence time. As for the aerobic efficiency, it was 48.9% in the conditions of 1/3 sludge volume and 6 days residence time. Meanwhile, the highest decrease in COD levels was 79.4% in the swab condition as much as 1/3 in the 6-day incubation time.

Published: May 2021

Abstract
Katuk is widely popular with its benefits for breastfeeding mothers. Katuk is also known as a plant with a high antioxidant content. This study aims to determine the effect of using variations in the ethanol concentration as an extracting solvent in producing Total Phenolics Content (TPC) and Total Flavonoids Content (TFC) and their activities in reducing DPPH free radicals. The dried katuk leaves were extracted by cold maceration method. The solvent used for extraction is ethanol with 3 variations in concentration: 50%, 70%, and 96% (absolute ethanol). TPC and TFC were determined by colorimetric method using a UV-Vis spectrophotometer. TPC was stated to be equivalent to gallic acid, while TFC was stated to be equivalent to quercetin. DPPH free radical scavenging activity was measured based on the IC50 value. The results showed that Katuk leaf extract produced from 50% ethanol solvent was able to produce TPC (42.18 ± 0.30 mg GAE / g), TFC (11.18 ± 0.38 mg QE / g) and reduction activity against DPPH radicals (IC50 = 88.33 ± 3.53 ppm). These were higher than ethanol with other concentrations. However, various things need to be considered when using this solvent given the high water content in the solvent.
The Effect Of Microwave AID Extraction Temperature Of Kedawung Leaves (Parkia biglobosa) On Antioxidant Activity And Flavonoid Leavels
Authors: Indrasari Ferika , Buanasari  
Published: May 2021

Abstract
Parkia biglobosa contains various ingredients such as alkaloids, saponins, tannins, flavonoids, and terpenoids. The flavonoid content in kedawung is thought to have an antioxidant effect. Antioxidants have the ability to provide electrons, bind and have a free radical chain reaction chain. Currently, the microwave-assisted extraction (MAE) method is widely used because extraction using MAE can increase the mass transfer rate of solutes from the sample matrix into the solvent compared to the Soxlet method. One of the factors affecting microwave-assisted extraction is temperature because a higher temperature will increase the solubility of the solute in the solvent. The temperature is limited by the boiling point of the solvent used. This study aims to determine the effect of temperature on the solvent in order to get the best extraction results. This method uses temperature variations to determine the highest levels of flavonoids from microwave-assisted extraction of leaves and bark of kedawung, the temperature used is 30°C, 40°C, 50°C, 60°C with ethanol solvent at a wavelength of 300 W. The results of this study say that there is an effect of temperature on the extraction results. microwave-assisted to the yield of kedawung leaf extract (Parkia biglobosa) at the best temperature of 40°C. Kedawung leaves (parkia biglobosa) have high levels of flavonoids so they have antioxidant activity.

Abstract
Research on microencapsule formulation and evaluation of ethanol extract by spray drying method was carried out to determine the effect of chitosan addition. It is hoped that from this research, chitosan microcapsule preparations can increase the benefits and stability of the extract. Microcapsule evaluation includes: microcapsule water content test, microcapsule size distribution using a Scanning Electron Microscope (SEM). The microcapsules formed were characterized by antioxidant activity using the 2,2-diphenyl-1-pikrilhidrazil (DPPH) method and total phenol content (folin-ciocalteu method). The results of the morphological evaluation showed that the microcapsules were evenly spherical for all formulas and they had an average moisture content of 4,612 ± 0.02. The anti-oxidant activity of DPPH-SA increased with the increasing concentration of added chitosan. Micro encapsules of the extract without chitosan and with the addition of 0-1% chitosan has antioxidant activity of 85,876 ± 1,897% and 86,014 ±0.570-86,725 ±0.313. In the TPC (Total Phenol Content) test, the results were 5.00 ± 0.01% and 5.49 ± 0.01-8.98 ±0.02%. Based on the research, it could be concluded that the microencapsulation with the addition of chitosan was able to increase the stability of the extract so that the antioxidant activity and total phenolic content could be higher.

Published: May 2021

Abstract
To overcome the solid waste problem, many city governments initiate and facilitate waste banks. Various studies have sought citizen participation in waste banks, but there is little attention to understanding how the coexistence of social capital can encourage waste banks’ practice. This study, therefore, aims at examining the social capital of the urban communities in the business process of waste banks. We looked in-depth at the practice of six waste banks in Tanjungpinang City, Kepulauan Riau, Indonesia. A series of interviews were carried out on the stakeholders of waste banks, such as management, customers, citizens, and households. We suggest that a number of social capitals shape the business process of waste banks, including trust, norms, social networks, and gotong royong. This research has a novel for the study of community-based waste management by considering the urban community’s social capital. Our study also has a worthy recommendation to the local government in managing waste management by corroborating social capital.
