Abstract

Waste is one of the causes of environmental problems, especially plastic waste. Therefore, education is carried out regarding knowledge about waste and waste utilization to minimize the accumulation of plastic waste. The aim of this education is so that high school students have environmental awareness and are able to be creative in utilizing surrounding waste to make environmentally friendly products that have high economic value. This education was carried out using a presentation method regarding waste materials and examples of waste utilization, namely coconut fiber waste which has the potential to be used as a strengthening material in the manufacture of biodegradable plastic. The results of the education provided show that there has been an increase in understanding regarding waste and its use on the "sangat mengetahui" indicator of 86.67%.

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

Eceng gondok (Eichhornia crassipes) merupakan gulma perairan yang memiliki pertumbuhan sangat cepat dan berpotensi menimbulkan permasalahan lingkungan. Namun, kandungan lignoselulosanya menjadikan eceng gondok berpotensi dimanfaatkan sebagai bahan baku biomassa untuk energi terbarukan. Penelitian ini bertujuan untuk menganalisis pengaruh pretreatment melalui variasi metode pengeringan dan ukuran partikel terhadap karakteristik biomassa eceng gondok sebagai bahan baku briket tanpa perekat. Proses pretreatment meliputi pencucian, pencacahan, pengeringan menggunakan sinar matahari, oven, serta kombinasi keduanya, kemudian dilanjutkan dengan proses grinding dan pengayakan. Analisa proksimat dilakukan untuk mengetahui perubahan kadar air, kadar abu, volatile matter, dan fixed carbon sebelum dan sesudah treatment termal. Hasil penelitian menunjukkan bahwa pretreatment termal mampu meningkatkan kualitas biomassa secara signifikan. Kadar air menurun dari 9,95% menjadi 6,50% dan volatile matter menurun dari 56,30% menjadi 24,80%, sedangkan fixed carbon meningkat dari 17,40% menjadi 43,16%. Metode kombinasi pengeringan menghasilkan biomassa yang lebih homogen dengan efisiensi energi yang lebih baik dibandingkan metode tunggal. Secara keseluruhan, proses pretreatment mampu meningkatkan karakteristik fisik dan termal eceng gondok sehingga berpotensi digunakan sebagai bahan baku biomassa alternatif yang ramah lingkungan dan berkelanjutan.

Abstract

Biogas is a renewable energy source that can be produced from organic waste, such as water hyacinth and cow dung. Utilizing these two materials through co-digestion has the potential to increase biogas production due to a better nutrient balance. This study aims to analyze the effect of the substrate ratio on the volume of biogas produced through anaerobic digestion. The method used is a Systematic Literature Review (SLR) by reviewing five relevant scientific articles based on certain inclusion and exclusion criteria. The parameters analyzed include the substrate ratio, biogas volume, and hydraulic retention time (HRT) or fermentation duration. The results of the study indicate that the substrate ratio has a significant influence on biogas production. Ratios that are close to balance, such as 50:50 and 47:53, tend to produce more optimal and stable biogas volume. Conversely, unbalanced ratios, such as 33:67, show varying results depending on operational conditions. Differences in biogas volume between studies are also influenced by other factors, such as retention time, raw material characteristics, and process conditions such as pH and temperature. The lignocellulose content of water hyacinth can inhibit the degradation process if not balanced with an adequate nitrogen source from cow dung. In conclusion, a balanced substrate ratio plays a crucial role in increasing biogas production, but it needs to be supported by controlling other operational parameters to achieve optimal and sustainable results.

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

Limbah organik yang menumpuk menyebabkan permasalahan di lingkungan. Solusi untuk mengurangi dampak tersebut adalah dengan melakukan pengolahan limbah organik tersebut. Salah satu limbah organik yang dapat dilakukan pengolahan yakni limbah kulit pisang raja menjadi bioplastik. Tujuan penelitian untukmengetahui pengaruh dari penambahan clay terhadap penguraian bioplastik berbahan dasar limbah kulit pisang raja. Penelitian yang dilakukan dibagi menjadi 2 tahapan. Tahap pertama adalah pengambilan kandungan patibdari kulit pisang raja. Sedangkan tahap kedua adalah pembuatan bioplastik dengan variabel 6, 8, dan 10% dari massa pati. Hasil penelitian yang dilakukan menunjukkan bahwa semakin tinggi persentase clay yang ditambahkan maka bioplastik semakin cepat terurai di dalam tanah. Hasil terbaik yang diperoleh adalah pada variabel clay 10%, persen fraksi berat residual pada hari ke 9 yaitu sebesar 30%.
