Abstract

In Indonesia, the problem of organic waste continues to grow in parallel with population increase and urbanization. However, the management of organic waste still relies on conventional methods that are often ineffective. Conversely, organic waste holds significant potential to be transformed into organic fertilizer and renewable energy through appropriate technological approaches. This study aims to design and implement an organic waste management system that incorporates automatic sorting and biogas conversion. The system is integrated with an Internet of Things (IoT)-based monitoring system at the 3R Integrated Waste Processing Site (TPST 3R) in Mulyoagung, Malang Regency. The system consists of an anaerobic bioreactor that produces methane gas and liquid fertilizer, an automatic sorting unit equipped with color, IR, and weight sensors, and an IoT dashboard for real-time monitoring of temperature, pH, and gas pressure. The research employed both technical and participatory methods, including community training and processing output evaluation. Results indicate a sorting efficiency of up to 92%, biogas production of approximately 22 m³ per ton of organic waste, and a significant increase in community participation. The system proved to be effective, adaptable, and capable of delivering positive social, economic, and environmental impacts.

Abstract

Ketindan Village in Lawang Regency is a coffee plantation area where most of the residents work as coffee farmers. Using simple methods for harvesting, the area produces various types of coffee, such as Robusta, Arabica, and several types of fermented coffee. One of the challenges faced is the large amount of coffee husk waste generated during the coffee bean peeling process. This coffee husk waste is typically discarded, causing negative environmental impacts on the surrounding area. One solution to address this waste issue is by educating the local community and conducting practical workshops on how to make briquettes from coffee husk waste. The residents appear enthusiastic and receptive to the information on how to produce briquettes using coffee husks as the main material. With this educational effort, it is hoped that the community will be able to process coffee husk waste into useful products that generate high economic value.

Abstract

The Ringin Asri Farmers Group (GAPOKTAN) in Kedungbanteng Village, Sumbermanjing Wetan District, Malang Regency faces a challenge in managing coconut waste, which tends to accumulate in large quantities and poses potential environmental risks. One proposed solution is processing the waste through pyrolysis at 600°C in the absence of oxygen, followed by a condensation stage to convert the resulting smoke into liquid smoke. This product offers multiple benefits, including reducing biomass waste and air pollution, as well as serving as a natural food preservative, pesticide, and plant antibacterial agent. Through a Community Service Program (PPM), the Department of Chemical Engineering, State Polytechnic of Malang, conducted technical training on liquid smoke production for GAPOKTAN members using lectures, group discussions, and hands-on demonstrations. The activity was met with high enthusiasm, and participants were able to easily understand the production process. This program is expected to enhance the group’s skills in utilizing coconut waste to produce natural preservatives, increase their economic potential, and reduce coconut waste generation in the area.

Abstract

Seiring dengan meningkatnya kebutuhan energi, cadangan bahan bakar fosil mengalami penurunan sehingga perlu adanya energi alternatif sebagai pengganti. Salah satu energi alternatif pengganti bahan bakar fosil adalah bioetanol. Bioetanol diproduksi dengan cara fermentasi dengan produk utama yang dihasilkan yaitu campuran etanol dan air serta produk samping berupa fusel oil. Kandungan pada fusel oil harus dipisahkan supaya mendapatkan etanol dengan kemurnian yang tinggi, salah satunya yaitu dengan distilasi. Dalam perancangan dan pengoptimalan proses distilasi maka diperlukan berbagai macam informasi, salah satunya yaitu data kesetimbangan uap - cair dari pasangan komponen yang akan dimurnikan. Penelitian ini bertujuan untuk memprediksi data kesetimbangan uap - cair menggunakan model UNIFAC pada tekanan 20, 50, dan 101,325 kPa. Prediksi kesetimbangan uap - cair sistem biner aseton + n-pentanol dilakukan menggunakan model UNIFAC dengan variabel yang digunakan yaitu tekanan 20, 50, dan 101,325 kPa dan fraksi mol fase cair pada rentang 0 – 1 dengan interval 0,05. Hasil prediksi kesetimbangan uap - cair sistem biner aseton + n-pentanol tidak menunjukkan adanya azeotrop sehingga pemisahan dapat dilakukan secara distilasi sederhana.

Abstract

Prediksi Kesetimbangan Uap-Cair bertujuan untuk mengetahui kesetimbangan uap-cair sistem biner Tersier Butanol + Isoamil Alkohol pada tekanan 101,3 kPa dan mengkorelasikan sistem biner tersebut dengan model Universal Quasi-Chemical (UNIQUAC). Prediksi diawali dengan menentukan fraksi mol campuran biner tersier butanol + isoamil alkohol dengan menggunakan persamaan Hukum Raoult pada tekanan 101,3 kPa, dimana tekanan uap total campuran cairan biner tergantung pada tekanan uap komponen murni dan fraksi molnya dalam campuran. Kemudian, data kesetimbangan yang didapat dikorelasikan dengan perhitungan model Universal Quasi-Chemical (UNIQUAC). Hasil prediksi dan korelasi menunjukkan hasil yang baik dikarenakan root mean square deviation (RMSD) dari hasil prediksi dan korelasi UNIQUAC diperoleh hasil yang relatif kecil. Parameter interaksi biner yang diperoleh dari hasil korelasi sangat berguna untuk optimasi kolom distilasi dalam proses pemurnian bioetanol.
