Abstract

Background: This research investigates the impact of tofu industry wastewater on the aquatic environment at the Suyanto Tofu Factory, Mojokerto. The tofu industry produces liquid waste that contains high pH, Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD), so it has the potential to pollute local rivers. Although the Suyanto Tofu Factory has wastewater treatment facilities, these facilities are currently not functioning, indicating an urgent need to design a new wastewater treatment plant. In this context, the research aims to determine the volume of wastewater produced, analyze BOD, COD, TSS and pH levels in wastewater, and design sustainable wastewater treatment facilities for the tofu industry. Methods: The method used is planning the design Constructed Wetland system with water hyacinth plants . This method is expected to minimize the environmental impact of tofu wastewater, protect the surrounding aquatic ecosystem, and comply with environmental regulations. Findings: This research found a wastewater treatment plant model using a pond system Sanita (Constructed Wetland ) which can reduce tofu waste effectively and sustainably is very important to maintain water quality and river ecosystems around the Suyanto Tofu Factory. Conclusion: The liquid waste at the Suyanto tofu factory has high levels of acidity and organic pollutants, with a pH of 3.91, TSS of 1050 mg/L, BOD of 2063 mg/L, and COD of 5135 mg/L. The factory uses a wastewater management design involving Sanita Pond processing with Eichhornia crassipes plants, effectively reducing the organic content in the waste. Novelty/Originality of this Study: By proposing a Constructed Wetland system for tofu industry wastewater treatment, this research introduces an innovative, sustainable solution tailored to local conditions, potentially revolutionizing waste management practices in small-scale food industries.

Abstract

Background: Indonesia is still an energy importer, especially in the form of crude oil and fuel products to meet the needs of its industrial sector. The reduced production of fossil energy, especially oil, as well as the global commitment to reducing greenhouse gas emissions, has prompted the Indonesian government to continue to support the role of new and renewable energy. The production of palm oil-based biodiesel is faced with a number of environmental problems, which may occur from the release of emissions during the production of FFB (Fresh Fruit Bunches), CPO (Crude Palm Oil), and biodiesel. Therefore, the purpose of this research is to compile an LCI (Life Cycle Inventory) covering the production of FFB, CPO, and biodiesel; analyze the environmental impact of the CPO bodysel production process which includes CO2 (eq) emissions, acidification and eutrophication; and develop a life cycle concept for biodiesel production from palm oil as a renewable energy. Methods: The method used in this study is a combination of quantitative LCA (Life Cycle Assessment) and AHP (Analytical Hierarchy Process) and qualitative. Findings: The results of this study are LCI in 1 ton of biodiesel consisting of NPK fertilizer of 141.1 Kg; herbicide (0.25 Kg); water (1578 m3), diesel oil (25 Kg); fresh fruit bunches of 5.67 tons; electricity of 33.8 kWh, POME (Palm Oil Mill Effluent) (3,47 m3), CPO needed for biodiesel conversion of 1.17 tons; methanol (0.41 tons), and 0.01 tons of Sodium Hydroxide. The total CO2 emission (eq) of biodiesel production from palm oil is 1489 Kg CO2 (eq), eutrophication is 1.12 Kg PO43- (eq) and acidification is 3.06 Kg SO2 (eq). With the largest contribution of CO2 (eq) emissions in CPO production and the contribution of eutrophication and acidification in oil palm plantations or FFB production (Fresh Fruit Bunches). Environmental hotspot of LCA, CO2 (eq) emissions from palm oil biodiesel production show that 53% mainly comes from POME (Palm Oil Mill Effluent) waste, other contributors are NPK fertilizers (23%), methanol (18%), and diesel oil (7%). Hotspot eutrophication showed that 61% mainly came from NPK fertilizer, methanol (20%), diesel oil (11%), and POME waste (8%). Hotspot acidification showed that 48% mainly came from NPK fertilizers, methanol (28%), POME waste (13%), and diesel oil (11%). Conclusion: The concept of a biodiesel production life cycle can be applied with the best alternative utilization of POME waste with a priority weighting of 0.357 and a CO2(eq) emission criterion of 0.494. From the optimization of the life cycle of biodiesel production with the use of POME, the potential for emission reduction is 667.2 Kg CO2 (eq). Novelty/Originality of this Study: This study's novel application of LCA evaluates the environmental impacts of biodiesel production from palm oil in Indonesia, identifying critical hotspots in CO2 emissions, eutrophication, and acidification. Additionally, it proposes an innovative optimization approach by utilizing POME to significantly reduce greenhouse gas emissions, highlighting a viable path for enhancing the sustainability of biodiesel production.

Abstract

Background: Red hot chili (Capsicum annum) is one of the important commodities for the community. The use of inorganic fertilizers in chili cultivation in the long run can disturb the soil balance. Therefore, it is necessary to make efforts to maintain and improve soil aggregation, so that soil particles more easily bind organic matter. One important effort is to apply organic fertilizer to the soil. One alternative liquid organic fertilizer that can be used is Ecoenzyme (EE). EE is the result of fermentation of organic kitchen waste such as leftover fruit and vegetable peels, molasses and water. This study was conducted to obtain the optimal concentration of EE on the growth and chlorophyll levels in Capsicum annum plants. Methods: There were 6 treatments in this study, namely E0 (no treatment as negative control), E1 (goat manure with soil: husk: fertilizer ratio of 1:2:1 as positive control), and different concentrations of EE, namely, E2 (EE 1 ml/1 liter of water), E3 (EE 5 ml/1 liter of water), E4 (EE 10 ml/1 liter of water) and E5 (EE 15 ml/1 liter of water). Findings: The results of significance data analysis with Duncan at the 5% level showed that treatment E1 was significantly different from the other treatments and treatment E4 showed different results but not significant with other EE treatments based on vegetative and generative growth parameters. Conclusion: The conclusion of this study is that the optimal concentration of EE to increase growth and chlorophyll levels in curly chili plants at a dose of EE 10 ml/1 liter of water. Novelty/Originality of this Study: The novelty of this investigation lies in its examination of the effects of ecoenzyme, an organic liquid fertilizer derived from fermented kitchen waste, on the growth and chlorophyll content of curly chili (Capsicum annuum) plants. This research is unique as it applies ecoenzyme to a horticultural crop that has not been extensively studied in this context, offering insights into sustainable agriculture practices and nutrient recycling.
