Abstract

Tofu industrial wastewater is a contributor to environmental pollution. Wastewater contains high levels of COD and TSS. The purpose of this study was to determine the effectiveness of reducing pollutant loads in tofu liquid waste by using the phytoremediation method using water jasmine (Echinodorus Palaefolius). The initial stage of the research was a preliminary test to determine the initial content of the waste. The acclimatization process is carried out by observing the process of plant growth during the research process. To maximize plant growth, dilution is carried out with various concentrations of 25% wastewater with 75% diluting water and 50% wastewater with 50% diluting water. Sampling was carried out every 12 hours for 5 days. The results showed that the highest effectiveness of COD reduction occurred in RFT 25% with a residence time of 12 hours at 39.83%, while for TSS parameters the highest effectiveness was at RFT 25% with a residence time of 12 hours by 69%.

Abstract

Water hyacinth (Eichonia crassipes) is one type of aquatic plant that has a fast growth rate. As a result, sunlight is blocked from entering the water, so that aquatic biota cannot carry out the photosynthesis process perfectly. This study aims to determine the value of C/N ratio, levels of Phosphorus (P), Potassium (K), pH, and temperature (T) in composting for 16 days with the addition of 200 mL of bioactivator effective microorganism 4 (EM4) in each reactor. Variations of raw materials used are Control Reactor (RK) containing 1.5 kg of water hyacinth; Treatment Reactor 1 (R1) contains 0.5 kg of water hyacinth + 1 kg of cow dung; Treatment Reactor 2 (R2) contains 0.5 kg of water hyacinth + 1 kg of rice bran; and Treatment Reactor 3 (R3) contains 0.5 kg of water hyacinth + 1 kg of cow dung + 1 kg of rice bran. The results showed that the combination of raw materials had an effect on the quality of the organic fertilizer produced. The combination of Treatment 3 (R3) produced organic fertilizer with the best quality, namely C/N ratio = 15.30%, pH = 7.16, macronutrient P = 4.91% and K = 8.36% which met the quality standard requirements.

Abstract

The Covid-19 pandemic has changed people's perspectives and behaviour in many ways, especially those related to health and the environment, especially in waste management. Waste management in the community that has been managed by the Trash Bank has also experienced congestion because generally, the managers (officers) do not dare to come into direct contact with garbage. As a result, waste piles up is not managed correctly and becomes a source of disease. Community service aims to provide socialisation and practice of standard operating procedures (SOP) for waste management during a pandemic. The method used is socialisation and exercise according to the SOP for Waste Management during the pandemic, including making hand sanitisers. The results obtained are that the community is no longer worried about waste management activities such as sorting waste and depositing dry waste to the Garbage Bank.

Abstract

The degradation of organic matter under anaerobic conditions, to produce a gas which is largely composed of a mixture of methane and carbon dioxide. This study aims to assess variations in the composition of kitchen waste, leaf litter with cow dung, measures the time the fermentation process and measure the rate of increase in gas pressure. Benefits of the research are expected to use waste kitchen waste, leaf litter and cow dung as an alternative energy source that is inexpensive and environmentally friendly. Experiments in this study conducted using household biogas reactor made of drum. The medium used for the growth of microorganisms is EM4. Leachate water samples obtained from the fermentation of garbage. Parameters measured were carbon, nitrogen, salmonella and mercury using measurement 1 methods for testing carbon-Organic conducted using Walkey and Black, test Nitrogen using semi-micro Kjeldahl modified, test Mercury by using qualitative analysis and quantitative mercury with tools Mercury Analyzer, Isolation and identification of Salmonella sp follow the Food and Drug Administration (FDA, 1995). Colonies that appear red with black middle gram staining, colony subsequently was identified towards Salmonella sp. biochemically. Biogas reactor performance is determined by measuring the increase in pressure and compare the variety of media used. The results obtained by the gas pressure is highest in the first variation is between 33-38 cm of water column takes about 11-12 days to produce the most gas. As for the second variation of the gas pressure generated by 29 cm column of water with gas formation time of 12 days and 3 variations of the gas pressure generated at 22-23 cm of water column with gas formation time of 11-12 days. Flame test done to prove the gas produced is methane (CHâ‚„) instead of COâ‚‚. From the results of the laboratory, leachate can not use a liquid organic fertilizer because it found Salmonella.
