Abstract

The Lapindo Mud Disaster is a phenomenon of overflowing mud from the earth's crust that occurred in Sidoarjo. One of the impacts of the hot mud eruption on agricultural fields. This study aims to analyze the content of heavy metal cadmium in the soil of rice fields around the Lapindo Mud. The heavy metals analyzed include Cadmium (Cd), which is used in the Geoaccumulation Index (Igeo), with Class 7 of Igeo used to determine the level of heavy metal contamination due to a disaster that occurs. The results of this study indicate the largest Cadmium (Cd) metal content in the sample in Gempol Sari village, at  1.08 mg / L and 0.007 mg/L, respectively. This exceeds the threshold set by the Environment Protection Ministry of China (EPMC) and contaminates the rice field environment. Based on the Igeo calculation (geoaccumulation index) applied to the concentration of heavy metals in rice field soil not contaminated by Cadmium, with an index value of 0 <igeo <1. Geoaccumulation Index figures in the research area, cadmium (Cd) content is within the normal range, so it is not included in the group of heavy metals that pollute the soil.

Abstract

Pencemaran udara merupakan salah satu permasalahan lingkungan yang berdampak luas terhadap kesehatan manusia, ekosistem, dan perubahan iklim. Pencemaran ini disebabkan oleh berbagai polutan seperti sulfur dioksida (SO2) dan nitrogen dioksida (NO2) yang dominan disebabkan oleh aktivitas industri dan pembakaran bahan bakar kendaraan bermotor. Oleh karena itu perlu dilakukan pemantauan kualitas udara agar bisa menentukan strategi dalam menjaga stabilitas kualitas udara. Penelitian ini untuk mengetahui tingkat kualitas udara di Kabupaten Mojokerto dan mekanisme pemantauan kualitas udara dengan metode passive sampler. Pemantauan dilakukan di 4 titik yang mewakili kondisi wilayah perkantoran, pemukiman, industri, dan transportasi. Titik pemantauan kualitas udara berlokasi di kawasan pemukiman, perkantoran, industri dan padat tranasportasi Kabupaten Mojokerto. Hasil dari pemantauan kualitas udara adalah rata-rata konsentrasi SO2 dan NO2 Kab. Mojokerto masih berada dibawah baku mutu sesuai dengan Permen LHK no 27 Tahun 2021. Air pollution is one of the environmental issues that has wide-ranging impacts on human health, ecosystems, and climate change. This pollution is caused by various pollutants such as sulfur dioxide (SO2) and nitrogen dioxide (NO2), which are predominantly generated by industrial activities and motor vehicle fuel combustion. Therefore, air quality monitoring is necessary to determine strategies for maintaining air quality stability. This research aims to determine the air quality level in Mojokerto Regency, the air quality monitoring mechanism using the passive sampler method, and the efforts undertaken to maintain air quality stability in Mojokerto Regency. Monitoring was conducted at four locations representing office areas, residential areas, industrial areas, and transportation zones. The air quality monitoring points were in residential areas, office areas, and dense transportation areas in Mojokerto Regency. The results of the air quality monitoring showed that the average concentrations of SO2 and NO2 in Mojokerto Regency were still below the quality standards stipulated by the Minister of Environment and Forestry Regulation No. 27 of 2021.

Abstract

Multivariable processes are the general classification for process features in the chemical industry. The variables in a single process unit interact with one another through more than one input and output. Since parameters interact with one another, changing one parameter's variable requires changing another parameter's variable as well. Further research is needed to determine how to create controllers that can handle interactions in the process. A MIMO control system is exemplified by the coupled tank system. Coupled tanks are present, and they communicate with one another by horizontal pipes. An interacting system can be represented using a coupled tank setup. Decoupling can be added to reduce the interactions that take place between variables. According to the results of the simulation, adding decoupling reduces the IAE value compared to not adding it. When the setpoint for tank level 1 (H1) was changed, the system's IAE value was 17.35 without the addition of decoupling, whereas it was 11.71 with it.

Abstract

Plastic waste is a growing environmental problem in Indonesia and negatively impacts environmental sustainability. This activity aims to raise public awareness about plastic waste management through the ecobrick method. The activity was carried out online through a National Webinar organized by the Chemical Engineering Study Program, Nahdlatul Ulama University, Sidoarjo. The webinar implementation consisted of preparation, implementation, and reporting stages. The material presented discussed the impact of plastic waste and the stages of ecobrick making, from the process of cleaning, drying, cutting, compacting, and assembling plastic waste into useful products. The results of the activity showed that participants gained a new understanding and awareness of the importance of wise plastic waste management. Participants also understood the benefits of ecobricks as an alternative environmentally friendly product that can be used as a simple construction material and decorative element. Thus, this activity is expected to encourage public participation in creating a cleaner and greener environment through sustainable plastic waste management.

Abstract

Indonesia has a wealth of flora with great potential to be developed as a functional food ingredient with economic value. One local plant that has this potential is the butterfly pea flower (Clitoria ternatea), which is known for its attractive natural color and beneficial bioactive compounds. This community service activity aims to introduce diversified butterfly pea flower processing to students through training in making food products as a home business idea based on local potential. The training was carried out using the method of material presentation, interactive discussions, and organoleptic product testing. The products developed include Azure Petal Tea, Citrus Spice Infusion, Blue Velvet Milk Tea, and Indigo Dream Pudding. The processing process is carried out using simple methods that are easy to apply. The results of the activity showed that participants were highly enthusiastic about the process of creating product characteristics and demonstrated a better understanding of the potential for diversifying butterfly pea flowers into value-added food products.

Abstract

The Buduran River in Sidoarjo Regency is a water source used by the community for domestic, agricultural, and fishery purposes. Increasing industrial and residential activities along the river have raised concerns about water pollution, particularly by organic matter and heavy metals. This study aims to analyze the water quality status of the Buduran River based on physicochemical parameters using the STORET method. Water samples were taken from two locations with two repetitions, a total of 8 samples, and tested for temperature, pH, BOD, COD, and the heavy metal Pb. The results showed that temperature and pH were in accordance with the Class II quality standards of the Republic of Indonesia Government Regulation Number 22 of 2021. The levels of BOD, COD, and the heavy metal Pb exceeded the established threshold. The BOD parameter at location points 1 and 2, namely 12.3 mg/L and 20.1 mg/L, respectively, exceeded the quality standard limit of 3 mg/L. The COD parameter at the second location point exceeded the quality standard limit of 29 mg/L because it was above 25 mg/L. The Pb metal parameter at location 1 was 1.63 and the second location was 1.22 mg/L. Both exceeded the quality standard limit. This indicates that the river in Buduran is experiencing water pollution. The role of the government and industrial managers in managing rivers due to industrial activities in mentoring and implementing technology.The scoring calculation using the STORET method showed that the water quality status of the Buduran River in Sidoarjo was moderately polluted at all points, with a score of -12 at locations 1 and 2 and a score of -18. These findings indicate the need for better waste management to maintain the sustainability of the river ecosystem.
