Abstract

This research discusses the processing of tofu wastewater with the aim of reducing and controlling the levels of pH, BOD, COD, TSS and temperature so as not to pollute the environment when dumped into rivers or other suitable places by simple reactors in few days. Water treatment process using bacterial from waste water as medium seems promising to develop since it does need any microorganism stater or other media like glucose. During the process of microorganism growth (seeding), the peak of MLSS was obtained on day 6 with 1560 mg/L. The other reason is wastewater from their wastewater processing is more suitable for microorganism cultivation because its effluent contains significant beneficial nutrienst and less of toxic compounds and harmful substances that interface with the growth of microorganism In same condition (pH and Temperature) in Acclimatization process can reach 77.45% after 7 days of treatment. After the detention time (18 hours) the results of COD number also greatly decrease with 5 hours recirculation with 8 L/min air flowrate and 86,51 % percentage of COD parameter decreased. This reseach is running in labolatory scale this problem must be recalculate to bring in large scale aplications, but this technology represents and effective, economilly and environmentally friendly process for tofu waste water treatment.

Abstract

The source of water that is still widely used by the community is well water, but there are still many wells that exceed the water quality standard. Like well water around Medayu, Surabaya. After testing the well water, several parameters were founds to exceed the specified clean water quality standard. These parameters are iron (Fe), manganese (Mn), lead (Pb), detergent, and KMnO4. This shows that the well water is not suitable for use. This study aims to treat well water that exceeds clean water quality standards using a fluidized bed reactor (FBR) by using media variations. The research variables are media variations (activated carbon, zeolite, and kaolin), detention time (20, 40, 60, and 80 minutes), and air pressure (2, 4, and 6 bars). The most effective results in this study are the use of zeolite as a media at a detention time of 60 minutes with an air pressure of 6 bars. Each % of parameter allowance for these results are Fe at 89,88%, Mn at 89,13%, Pb at 93,75%, Detergent at 90,74%, and KMnO4 at 95,38%.

Abstract

Management and processing of organic solid waste are simpler than inorganic solid waste. Organic solid waste was more easily decomposed if it was disposed of or buried in the soil. There was no area for the community to be heaped up the organic solid waste. Moreover, the water level is relatively shallow, making it possible for organic waste to mix with groundwater. Corn cobs were an organic solid waste that was mostly produced by the seller of roasted corn or boiled corn on the side of the road. This corncob waste has a contribution to the increase in rubbish in solid waste disposal. For this reason, the use of corn cobs was necessary. This corncob waste can be used as handicrafts to replace handicrafts made from plastic. The community, especially housewives, has the potential to innovate in making handicrafts. It's just that it requires supportive technology for creativity. The results of this community service activity were several handicrafts made from corn cobs that have been processed and added with glycerol as a plasticizer. The method of reusing corncob waste into handicrafts has contributed to reducing corncob waste by corn sellers on the roadside. This community service activity in addition to increasing the creativity of housewives, also indirectly reduces the corn cobs heap in solid waste disposal.

Abstract

The abundance of microplastics in Surabaya's surface water can disrupt the sustainability of river ecosystems and harm humans because most of the raw water used by the people of Surabaya comes from surface water. Microplastics less than 5µm in size contain harmful chemicals such as Polychlorinated Biphenyls (PCBs) and are toxic. One alternative treatment is to reduce the levels of microplastics in the electrocoagulation process. Electrocoagulation is the process of clotting and deposition of fine particles in water using electrical energy. Microplastics contained in the water are removed through flocculation and deposition processes. This study aims to determine the effectiveness of the electrocoagulation process on reducing microplastic levels. The variables of this experiment are the distance of the electrodes (1.5 cm, 2 cm; 3 cm, and 5 cm), and the detention time (15 minutes, 25 minutes, 30 minutes, 45 minutes). This research was set up by using a reactor with a volume of 5 liters and a settling time of 30 minutes.

Abstract

Tofu industry produces the waste that contains a lot of organic substances. The waste is discharged into the environment without any treatment process, it will cause the environmental pollution. In Indonesia, tofu industries (the small-scale industry) mostly do not treat their waste due to the problem of the high cost treatment process. The purpose of this research is to know the effective and economically reasonable that can be used by tofu producers to process tofu waste, especially liquid waste so not damage the environment. Water treatment process using bacterial from waste water as medium seems promising to develop since it does need any bacteria starter or other media like glucose. The other reason is wastewater from food processing is more suitable for microorganism cultivation because its effluent contains significant beneficial nutrient and less of toxic compounds and harmful substances that interface with the growth of microorganism in same condition (pH and Temperature) in Acclimatization process can reach 83.2% after 7 days of treatment. After the detention time (18 hours) the results of COD number also greatly decrease with 2.5 hours recirculation at 12 L/min air and pH 3.7 and 4.5 it can reach 85% and 86% of removal COD.
