Environmental Analysis of Tofu Production in the Context of Cleaner Production: Case Study of Tofu Household Industries in Salatiga, Indonesia

Abstract

Tofu is a soy-based food that is frequently consumed by Indonesian as a protein source. It is usually produced by household industries using traditional technology, which currently experiencing environmental problems with respect to the inefficiency of resource usage and inadequate waste disposal. Therefore, cleaner production strategy is potential to be implemented by previously mapping the current problems faced by the industries. This study aims to present an environmental analysis on tofu production in Salatiga in the context of cleaner production. In addition to provides information about the current production process and explains waste management performed by the industries, this study describes how the people in Kalitaman-Salatiga consider environmental issue around the tofu production. This study was conducted by a qualitative approach using interview, observation, and documentation. Laboratory analysis was conducted to provide supporting data. The results showed that only a small proportion of the tofu production process in Kalitaman meets the indicators for cleaner production in term of using raw materials efficiently and reusing solid wastes. Wastes in the form of smoke and wastewater are still disposed without prior treatment. The BOD5, COD, and TSS contents of tofu wastewater exceed the quality standard set by the Indonesian government. Although the respondents understand the negative impact of pollution to ecosystem, they are not yet concerned because it does not show a direct detrimental impact on their community. Therefore, raising environmental awareness is required in order to protect the ecosystem and to prevent environmental deterioration.

Valorization of Glycine max (Soybean) Seed Waste: Optimization of the Microwave-Assisted Extraction (MAE) and Characterization of Polyphenols from Soybean Meal Using Response Surface Methodology (RSM)

“…Soybean meal is a by-product of the soybean seed industry, which is commonly used for animal feeding [1,2] or rejected directly in nature, then causing serious problems to municipalities and to the environment [3,4]. In order to reduce pollution related to soybean seed industry's by-products and wastes, numerous usages have been proposed and tested: broiler breeding [1], growing substrate or source of specific compounds for microorganisms [3,5], biosurfactants [6], and biodiesel production among others.…”

Tofu Wastewater Treatment with Variation of Air Rate in Aeration Suspension System

“…In Indonesia, tofu and tempeh are usually produced using traditional technology. The number of tofu and tempeh consumption per capita per week increased by 3.80% and 2.06% consecutively in 2017, compared to 2013 (Nugroho et al, 2019). Enhancement consumption of tofu and tempeh is directly proportional to the amount of production in the tofu industry and related to the amount of waste generated.…”

The Correlation Between Economic Activities to Water Pollution in Banyumas District, Central Java Province, Indonesia

“…Measures can be made through wastewater management. Wastewater management is a system that aims to purify wastewater so that when it is released into the environment it does not cause water pollution [23]. Wastewater management comprises collection, management, disposal, and reuse systems [24].…”
