Abstract

Tujuan dari Program Pengabdian kepada Masyarakat (PkM) ini adalah menghadirkan solusi inovatif bagi UMKM Kopi Jempol Supri melalui penerapan Smart Roaster berbasis Internet of Things (IoT) dengan web monitoring serta Web Pencatatan Stok dan Laporan Keuangan. Permasalahan utama yang dihadapi mitra adalah risiko kegosongan biji kopi akibat pengendalian suhu manual serta pencatatan stok dan keuangan yang masih dilakukan secara konvensional sehingga sering menimbulkan kesalahan. Metode pelaksanaan mencakup sosialisasi, pelatihan, dan pendampingan kepada mitra, serta pengujian sistem dengan pendekatan partisipatif. Uji coba dilakukan pada sensor termokopel, sensor MQ-135, website Smart Roaster, dan Web Pencatatan Stok dan Laporan Keuangan. Hasil menunjukkan adanya peningkatan signifikan pemahaman mitra melalui perbandingan pretest dan posttest. Sensor termokopel membuktikan bahwa kopi mencapai kematangan optimal pada suhu 223–232 °C dengan durasi 80–110 menit, sedangkan sensor MQ-135 menghasilkan data asap yang progresif sesuai tahap roasting. Website Smart Roaster berjalan baik sesuai skenario blackbox testing, mampu menampilkan suhu dan asap secara real-time serta mengendalikan mesin dari jarak jauh. Web Pencatatan Stok dan Laporan Keuangan juga berfungsi optimal, terbukti melalui uji blackbox dan memperoleh skor 90,52% (sangat baik) berdasarkan ISO/IEC 25010 pada aspek functional suitability, performance efficiency, dan usability. Kesimpulannya, penerapan Smart Roaster IoT dan Web Pencatatan Stok dan Laporan Keuangan berhasil meningkatkan konsistensi mutu kopi, mengurangi kerugian produksi, serta mempercepat dan mengefisienkan pengelolaan administrasi pada UMKM Kopi Jempol Supri.

Abstract

The traditional drying method has many weaknesses, namely it is very dependent on the weather, so that drying takes a long time. Traditional drying methods result in frequent contamination of dust, dirt, insects, and if wet they are prone to moss growth due to delays in drying during cloudy or rainy weather. This study designed a coffee bean dryer with electric power which is the result of converting solar energy with the help of photovoltaic which is first stored in the battery. The main components of this tool are: drying chamber, drying roof, tray, thermostat, heating element, this test is carried out to determine changes in seed moisture content, required power and efficiency. The temperature is set at 50°C with a fan speed of 3m/s. The fastest decrease in water content occurred in the mass of 1 kg coffee bean samples starting on June 22, 2022 from 28.5% water content to 12% moisture content. Meanwhile, the longest decrease in the water content of coffee beans was at a mass of 2 kg coffee beans on June 24, 2022, the initial water content of coffee beans was 29.3% to 13.2%. The greater the mass of the coffee beans to be dried, the greater the time required to dry the coffee beans using a dome dryer. The maximum power is in the Sukmailang area, Pesawaran district which has a plateau as high as 1200 meters above sea level (MDPL) with an average power of 11.38 Watt. The highest power is produced at 12:00 WIB with a value of 16.49 Watts. The use of solar panels in the Sukmailang area, Pesawaran Regency which has a plateau as high as 1200 (MDPL) is still not effectively utilized because the results obtained have an average efficiency value of 2.22%

Abstract

This study aims to conduct a Remaining Life Assessment (RLA) on the shell 1st stage separator. The process is carried out through the stages of calculating the minimum permissible shell thickness, MAWP, corrosion rate, and determining the operational feasibility of the separator. The method used is non-destructive test (NDT) inspection to determine the minimum actual thickness. Calculations were made using the API 510 standard. Based on the evaluation of the minimum thickness and MAWP value, the 1st separator shell is still feasible to operate. The ST corrosion rate that occurred in 2012, 2016, and 2019 was 0.123 mm/year, respectively; 0.007 mm/year; and 0.023 mm/year. While the LT corrosion rate is 0.089 mm/year, RLA analysis shows that the remaining life in 2012 was 93.75 years, 93.42 years in 2016, and 92.63 years in 2019. Thus, the shell 1st stage separator is still feasible to operate.
