Abstract

Tofu wastewater has negative impact on the river ecosystems and local residents because its smell and acidity. Therefore, this research aimed to design tools and test pH and temperature sensors based on Internet of Things (IoT) for monitoring the results of the installation of tofu waste wastewater treatment (WWTP) system in real time as wastewater quality monitoring system development thus it capable for wastewater monitoring intensively. Methodology of this research was experimentally for designing monitoring tools, which at tool design stage using an ESP 8266 microcontroller, pH4502c and DS18B20 as pH and temperature sensors, respectively. And also, it was communicated with Arduino IDE and Blynk software to create program code on the microcontroller and as monitoring on the computer server and smartphones, respectively. The used statistical compatibility test was percentage error, validity and reliability tests based on the monitoring tool data response to observed its suitability of the wastewater monitoring tool set for sustainability in home industries. In the %error test, there were results in reading values by the pH and temperature sensor of 0.92-1.45% in the tofu waste and whole neutralization, coagulation, sedimentation and filtration compartments; however, there was %error result of 0.92-7.31% on the pH sensor for the tofu wastewater tub. There were very valid and reliable results on tofu waste and whole compartments of the WWTP. Based on these results, the wastewater monitoring tools set was declared suitable for continuous use in the tofu industry with recommendations for routine calibration at least every 3 days of use.

Abstract

Semiconductor photocatalysts have great potential in solving environmental problems. The photocatalyst process using a semiconductor is one of the technology to oxidize organic compounds such as dyes. Orange peel (KJ) is one of the adsorbents that have the potential for purification of dyes that increase the photocatalytic activity of ZnO material. This study aims to determine the optimum variation of KJ-CTAB to be added to ZnO material. The results of the synthesis of ZnO/KJ-CTAB varasis 1:25, 2:25, and 3:25 (w/v) using the wet impregnation method were characterized on IR, XRD, SEM, DR-UV, and BET instruments. The results showed that FTIR also showed the presence of ZnO bonds in all samples, C-H in samples varied from 1:25, 2:25, and 3:25 (w/v). The XRD results showed that the percentage of crystallinity decreased and the SEM results showed that ZnO/KJ-CTAB 1:25 had a more homogeneous morphology. Based on the results of DR-UV ZnO/KJ-CTAB 1: 25 (w/v) has a band gap energy value of 3.20 eV which is good for use in photocatalyst processes. BET results show that all samples belong to the mesoporous size.

Abstract

Every industry has special attention to environmental preservation; however, it has become an unresolved problem in the industrial center of tofu village. Based on the analysis, there were problems related to liquid waste produced by tofu craftsmen that doesn’t meet the Quality Standards for liquid waste of the Food Products Industry, limited costs, land, and space thus that it didn’t meet the adequacy of space for Wastewater Treatment Plants (WWTP). The PKM (Community Service Program) activity aimed to implement Green Economy Concept on Integrated WWTP Systems and Sensors for the Kediri Tofu Industry as an effort to solve the waste problem in the tofu industry. This activity began with field observations, compatibility and requirements analysis, construction design and designing WWTP systems and sensors, small-scale trials, analysis, and evaluation. The WWTP system used involves components of pre-treatment, neutralization, coagulation and flotation, sedimentation, and filtration. The designed sensors included Arduino Nano-based pH meter and TDS meter sensors that were connected to computers and smartphones by Arduino IDE and Blynk software. It was hoped that this activity might spur business actors to actively participate in solving waste problems and reducing environmental impact pollution with all the space and cost limitations.
