Tofu industrial liquid waste contains high organic matter, if it is discharged into the environment without being processed first, it will have a negative impact in the form of environmental pollution. Currently, most of the tofu industry is still a small household scale industry, for example in Bara-baraya one of the tofu industries is not equipped with a wastewater treatment unit. The Bara-baraya tofu industry is located right in the middle of a residential area, so this can cause disturbance to the surrounding environment. This study aims to determine the quality of the tofu industrial wastewater in the Bara-Baraya Timur Village, Makassar City in terms of pH, BOD, COD, and TSS parameters. The type of research used is observational research with a descriptive approach. The method of examining samples from the parameters of BOD, COD, TSS and pH in the tofu industrial wastewater refers to the SNI for water quality testing methods and is examined at the Makassar Health Laboratory Center. The results of the inspection of the quality of tofu waste water compared to the Minister of Environment Regulation No. 5/2014 are the pH parameter 3.85 (not eligible), COD parameter 499 mg/L (not eligible), TSS parameter 4.777.50 mg/L (not eligible), and BOD parameters 1.771.88 mg/L (not eligible). The conclusion in this study is the quality of tofu wastewater in waste samples that have not undergone treatment at the wastewater treatment plant (IPAL) located in the tofu industry located in RW 4, Bara-Baraya Village, Makassar City, does not meet the requirements and exceeds the quality standards that have been set. determined by the government so that it can cause pollution to the surrounding environment.

The number of industry in Indonesia continues to increase along with the increase in population. The increase in the construction industry will have a positive impact as increasing social and economic life of society. However, the negative impact is the increasing environmental pollution such as air pollution, water pollution and soil. One of the causes of water pollution industrial waste discharged into water bodies without treatment beforehand. Various attempts have been made by the government for the supervision and control of water pollution by issuing laws and regulations, permit to dispose of liquid waste and Proper Program. Nevertheless, there are still companies and industries that discharge wastewater does not meet the requirements is allowed. One effort in monitoring, particularly in the waste disposal industry by applying online monitoring in real-time at the outlet WWTP Industry. This technology is expected to real-time monitoring can be done by government agencies (Ministry of Environment and Forestry and the Regional Environmental Agency) and can send an early warning when there is pollution. This monitoring system generally consists of sensors, data loggers, data communications and data centers. Sensor data from industrial wastewater outlet will be sent to the data center continuously, then the data will be stored and processed by database system and then displayed on Internet. Keyword : industrial wastewater pollution, online monitoring, wastewater quality, WWTP

The location of tempe processing adjacent to the settlement causes problems. The resulting liquid waste makes people uncomfortable. This is presumably because the liquid waste has not been managed properly, because it is only dumped into the drainage channel. The majority of tempe industrial entrepreneurs are home industries who are not aware of creating a healthy environment by paying attention to liquid waste processing. There are many studies on technology for the tempe industrial wastewater problem, but each technology has advantages and disadvantages. It is necessary to have a system to choose the technology that suits the waste conditions. This research takes a case study in Karanganyar Regency. The Analytical Hierarchy Process (AHP) method is a method of determining priority scale that can accommodate all aspects. Furthermore, a sequence of criteria can be arranged as needed. The results of the analysis with AHP are: technology criteria 31.09%; environment 28.65%; economic 21.74% and social 18.53%. Environmental sub-criteria showed the results of the removal of ammonia 40.56%; treated water quality 30.74%; the amount of mud is 18.91% and the emission level is 9.80%. Technology sub-criteria are ease of operation 28.67%; land area requirement 28.56%; service life of 28.05% and the potential of technology in the midification of 14.72%. Economic sub-criteria with the results of operating costs 34.21%; installation cost 33.28%; maintenance costs 23.78% and HR costs 8.73%. Social sub-criteria with the results of the need for employment of 49.10%; readiness of human resources 19.33%; implementation of construction 16.74% and aesthetics 14.82%. The results of the AHP can be used as input for tempe entrepreneurs, the government and the community to improve the environmental quality of the tempe industrial wastewater. It is hoped that entrepreneurs will find it easier to determine the appropriate technology to treat the tempe industrial liquid waste.

The Impact

One of the types of tofu industries in Indonesia is that the small-scale tofu industry was located in the East Jombor, Ketapang Village, to be precise, on the Blorong River. The Simplified Tofu Industry, with a 1300 kg/day production capacity, produces liquid waste that is disposed of into the Blorong River with a BOD parameter of 2,726 mg/L, COD of 4,972 mg/L, and TSS of 388 mg/L.These values greatly exceed the quality standards based on the Regional Regulation of Central Java Province Number 10 of 2004 concerning Tofu Industry. The entry of these pollutants into the Blorong River, over time, can cause water bodies to become toxic and pollute the Blorong River. Therefore, one of the efforts to protect this river's environmental conditions is to increase the efficiency of the Wastewater treatment plant and substitute the determined fuel through alternative scenarios. In the MBBR scenario, substituting diesel fuel into biomass is a type of biodiesel. Biodiesel has an advantage for the fire tube boiler industry because it can reduce exhaust emissions compared to diesel. Meanwhile, the existing wastewater treatment is substituted for the MBBR unit. The choice of MBBR as a wastewater treatment unit is because it is economical, does not require large land, is simple in development design, and is accessible in operation and maintenance. In the second scenario (SBR), a transition of Diesel fuel to LPG. LPG as a fuel input in the cooking process will result in cleaner emissions, especially on the SO2 parameter, and better because it has a higher heating value than diesel, 47,3 Tj/Gg. Both scenarios are analyzed regarding the magnitude of the impact on the environment using the OpenLCA method. The resulting impact magnitude on the OpenLCA method from each alternative is evaluated to obtain the best scenario. In the Tofu Industry, the best design the resulting impact is smaller than the SBR alternative.

New Treatment

With increasing stress on existing wastewater treatment systems, it is necessary either to upgrade the treatment unit(s) or install an entirely new treatment plant. Obviously, the upgrading is preferred over the alternative of having a new system. Keeping this in view, in the present project, an attempt has been made to explore the possibility of upgrading existing facultative ponds using water hyacinth. Bench-scale batch studies were designed to compare the performance of hyacinth treatment system with facultative ponds. Investigations were carried out with synthetic wastewater having COD in the range of 32.5-1090 mg/l. The efficiency of COD removal in water hyacinth ponds was 15-20 percent more than the facultative ponds. Based on the results, an empirical model has been proposed for COD removal kinetics. In the second phase of the project a hyacinth pond was continuously operated. BOD, COD, TS, TN, TP, pH, and DO were regularly monitored. However, the DO of the effluent from hyacinth treatment system was considerably reduced. Effluent should be aerated before it is discharged. The results indicate that the existing facultative ponds can be stalked with water hyacinth to improve their performance as well as hyacinth treatment systems can be installed to support the conventional treatment.

A general methodology for the study of water quality in rivers is presented. The paper consists of four parts. In the first part the general characteristics of the area of study, which is the Beli Lom river, and its major pollution sources are presented. The effluent of the Razgrad Wastewater Treatment Plant (RWWTP) has been identified as the most significant pollution point source, due to the inadequate performance of the plant. The second part deals with data collection and processing. Four series of data have been collected, including physical, flow and water quality characteristics. In the third part a 1-d, finite-difference, second-order model is presented. In the fourth part, the model is calibrated, for the determination of its main coefficients, and is successfully verified by predicting the BOD and DO concentrations in the Beli Lom river for all series of data. Finally, the model has been applied to determine the maximum BOD and minimum DO effluent concentrations of the RWWTP, so that a minimum DO concentration is maintained throughout the river.
