Penyebaran Covid-19 yang masih terus merebak di kalangan masyarakat saat ini membuat pemerintah mengeluarkan anjuran bagi masyarakat luas untuk mematuhi seluruh protokol kesehatan dalam rangka memerangi Covid-19. Di antara protokol kesehatan tersebut salah satunya adalah kewajiban mengenakan masker baik masker kain untuk masyarakat biasa maupun masker medis bagi tenaga kesehatan. Meningkatnya minat masyarakat dalam mendapatkan masker kain turut menjadi ladang usaha bagi sebagian pengusaha untuk memproduksi masker kain. Tujuan dari penelitian ini adalah untuk melakukan analisis pemetaan tingkat produksi masker kain pada produsen masker kain. Metode yang digunakan adalah metode K-Means dan Fuzzy Sugeno. Berdasarkan metode K-Means diperoleh pengklasifikasian cluster dengan kategori produksi tinggi, sedang dan rendah sedangkan metode Fuzzy Sugeno memberikan gambaran peramalan/prediksi perkiraan jumlah produksi disesuaikan dengan jumlah permintaan.

Bioetanol merupakan salah satu energi terbarukan yang dapat diproduksi dari berbagai bahan seperti sorgum, tebu atau bahkan substrat dari limbah industri makanan. Pembuatan bioetanol melibatkan proses distilasi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh lamanya waktu distilasi etanol-air terhadap konsentrasi overhead product dan bottom product yang keluar dari kolom distilasi. Metode dalam penelitian ini terdiri dari tahap persiapan, distilasi dan tahap analisa. Konsentrasi etanol ditentukan melalui pengukuran indeks bias menggunakan refraktometer. Dari hasil penelitian yang telah dilakukan dapat disimpulkan bahwa semakin besar indeks bias larutan etanol maka semakin besar konsentrasi larutan. Semakin lama waktu distilasi maka konsentrasi overhead product semakin besar. Hal ini berbanding terbalik dengan konsentrasi larutan di bottom product yang semakin kecil dengan bertambahnya waktu distilasi.

Clove oil is one of the essential oil products produced from Kare Village, Kare District, Madiun Regency. In the village there are several clove oil refining business groups, one of which is the "Rejo Tumetes" Business Group. The distillation process in the business group is carried out in a distillation unit consisting of one distillation tank, furnace, cooling in the form of a pipe dipped in a cooling pond measuring 7.5 meters long with 3.5 meters wide and a depth of 1.5 meters equipped with separating clove oil products in the form of multi-level drums. Cooling is the most important thing from the refining process, if the cooling is not optimal then the oil produced is also not optimal. This is because not all the oil that comes with water vapor can be condensed. The problem faced by partners at this time is that the process of condensation has not been maximized because it still uses a cooling pool. To solve this problems, we made a cooling system in the form of a condenser in this Community Service Program. To achieve the target output in accordance with the problems faced, several activity plans are used which include counseling, demonstrations and training, field visits, procurement of equipment as well as mentoring and monitoring evaluation followed by the “Rejo Tumetes” Business Group in Kare Village. The result of this program is the achievement of a refining business group that is able to make and operate the condenser independently so that the clove oil vapor cooling process can run perfectly and more clove oil produced. ABSTRAKMinyak cengkeh merupakan salah satu produk minyak atsiri yang dihasilkan dari Desa Kare Kecamatan Kare Kabupaten Madiun. Di desa tersebut terdapat beberapa kelompok usaha penyulingan minyak cengkeh, salah satunya adalah Kelompok Usaha “Rejo Tumetes”. Proses penyulingan di kelompok usaha tersebut dilakukan di unit penyulingan yang terdiri dari 1 (satu) buah ketel tangki destilasi, tungku pemasakan atau furnace, pendingin yang berupa pipa yang dicelupkan ke dalam kolam pendingin yang berukuran panjang 7,5 meter dengan lebar 3,5 meter dan kedalaman 1,5 meter yang dilengkapi dengan pemisah produk minyak cengkeh berupa drum-drum bertingkat. Pendinginan merupakan hal terpenting dari proses penyulingan, jika pendinginan kurang optimal maka minyak yang dihasilkan juga tidak maksimal. Hal ini dikarenakan tidak semua minyak yang terikut uap air bisa terembunkan. Permasalahan yang dihadapi mitra saat ini adalah proses kondensasi yang belum maksimal dikarenakan masih menggunakan kolam pendingin. Untuk menyelesaikan permasalahan tersebut, kami membuat sistem pendingin berupa kondensor dalam Program Pengabdian Kepada Masyarakat ini. Untuk mencapai target luaran sesuai permasalahan yang dihadapi, digunakan beberapa rencana kegiatan yaitu meliputi penyuluhan, demonstrasi dan pelatihan, kunjungan lapangan, pengadaan peralatan serta pendampingan dan monitoring evaluasi diikuti oleh Kelompok Usaha “Rejo Tumetes” di Desa Kare. Hasil dari program ini yaitu tercapainya kelompok usaha penyulingan yang mampu membuat dan mengoperasikan kondensor secara mandiri agar proses pendinginan uap minyak cengkeh dapat berjalan sempurna dan minyak cengkeh yang dihasilkan semakin banyak.

Water is one of the important components of human life or other living things. With the increasing number of residents, the need for clean water has also increased. However, this increase in demand is not offset by the availability of clean water due to the lower quality of water produced by the water treatment plant. Therefore, it is necessary to do alternative water treatment so that clean water needs can be sufficient. One method of processing clean water that can be done is the Jar test method. This study aims to determine the effect of coagulant dose addition on water quality parameters including pH, turbidity, TDS and total hardness of the Manisrejo City Madiun well water sample after water treatment. The research method is carried out through three stages, namely the preparation stage, the instrument analysis stage and the experimental stage. Where the type of coagulant used is Poly Aluminum Chloride (PAC). From the research that has been done, the optimum PAC coagulant dose is 43 mg / l. The conclusion obtained in this study is that the greater the coagulant dose added to the water sample, the smaller the pH value, the value of turbidity, the TDS value and the total hardness of the water sample.

Carbon dioxide (CO2) is an acidic and corrosive gas, and the presence of this gas in the piping system can cause various problems in the industrial sector. Therefore, the CO2 must be separated from the gas stream. One of the CO2 gas separation processes from the gas stream is carried out in a CO2 removal unit, where a desorption unit serves as a solvent regeneration step. Therefore, this study aims to develop a rate-based model and simulation of the reactive desorption process of CO2 gas in a sieve tray column. The rate-based model in the reactive desorption process of CO2 gas is based on film theory, the liquid in the tray is assumed completely agitated due to gas bubbling, the flow pattern of gas is plug flow, and the effect of the reaction on the mass transfer follows the enhancement factor concept. The number of trays used in this study was 20. In addition, the effect of several variables, such as: desorber pressure, rich amine temperature, rich amine flow rate, and reboiler load, was also assessed on the CO2 stripping efficiency. The accuracy of our prediction model is 1.34% compared with industrial plant data. Compared with the chemical engineering simulator simulation results, the average deviation is 4%.

The primary source of income for the residents of Kenongorejo Village in Madiun Regency is agriculture. The village is situated in a mountainous region. This village produces an increasing amount of agricultural waste due to the abundance of agricultural products. Environmental pollution may result from the amount of agricultural waste that has not been appropriately recycled. Even if part of the agricultural waste has been used as animal feed, the residents of this village still have a concern with the vast amount that has been wasted. It takes environmentally responsible technologies to transform these agricultural wastes into products with a marketable value. The service team's recommendation is to offer training sessions on the production of eco-enzymes, which source their primary raw material from agricultural waste. In order to improve comprehension and abilities in creating eco-enzymes, the strategy employed in this community service activity includes identifying partner requirements, counselling, training, evaluation, and monitoring, as well as post-activity help. The majority of the women of PKK Kenongorejo Village are the main audience for this project. Eco-enzymes, which can be utilised for domestic requirements and sold to the general public as natural cleaning solutions, are the end products of this service activity.

Porang (Amorphophallus oncophyllus) is a tuber plant originating from Indonesia. This plant is less well known compared to other tuber plants. Porang has various important uses, especially in the food and industrial sectors. Indonesia ranks 5th as the largest supplier of porang in the world. Drying porang is an important stage in the post-harvest processing of porang plants. The drying process must be done carefully so as not to damage the quality of the porang. The right drying method, appropriate drying temperature, and humidity control must be considered to achieve optimal drying results. A tray dryer is a drying device that contains shelves to store the material being dried. Drying with this tool uses hot air gusts that are passed over the material being dried. The aim of this research is to determine the effect of drying temperature variations on the moisture content and drying rate of porang using a laboratory-scale tray dryer. Drying is carried out on stick-shaped porang with a thickness of 1 cm and a total weight of 125 grams. The temperature variations in this drying are 50OC, 60OC, and 70OC, with a drying air speed 1 m/s. The research results show that the higher the drying air temperature in the tray dryer, the lower the moisture content in the porang and the faster the drying rate. When the drying air speed and porang thickness are constant, the optimal porang drying temperature is 70OC.
