Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memoderenisasi alat mesin yang digunakan memproduksi gula merah agar dapat mempermudah dan mempercepat proses produksi serta untuk dapat menekan total biaya operasional. Selain itu kegiatan ini ditujukan untuk membantu meningkatkan produksi dan kualitas produk gula merah bagi UKM Gula Merah di Kabupaten Kediri. Namun demikian fokus kegiatan yang dilakukan pada kegiatan pengabdian ini yaitu proses pembuatan beberapa komponen evaporator, penyuluhan alat dan pendampingan kepada anggota UKM Gula Manis. Hasil dari kegiatan pengabdian kepada masyarakat ini yaitu berupa bantuan alat yang meliputi mainholeevaporator, system perpipaan dan pompa kepada mitra agar dapat menjalankan produksi gula merah dengan teknologi yang sudah dirancang. Hasil pengujian dan perhitungan dari performansi alat juga telah dilakukan untuk mendukung proses operasi menggunakan evaporator. Selain itu kegiatan sosialisasi proses pembuatan gula merah kapasitas industri juga telah dilaksanakan dengan baik.

Abstract

Porang is rich in glucomannan, making it valuable in food and non-food applications, often processed into porang flour. Size reduction of porang flour into porang powder is a crucial stage to meet the particle size standard of commercial konjac powder.  However, this stage is rarely explored, especially when using a roller mill machine.  This study aims to evaluate the performance of a batch roller mill machine on the particle size and colour of porang powder with various porang flour masses. The mass of porang flour used in this study was 100, 200, and 300 g, which were coded M100, M200, and M300, respectively, and the results obtained were analyzed descriptively. The particle size distribution was assessed using a particle size analyzer CILAS 1090-dry method, and colour was observed using the Colour Reader Minolta CR-10. The results showed that different mass variations of porang flour produced different particle size distribution patterns in the porang powder produced. Mathematically, the parameters d10, d50, d90, and the average diameter of porang powder follow an exponential equation as a function of the increasing porang flour mass, with R2 values ranging from 0.97 to 0.99. In addition, the average diameter of porang powder from treatment M100 was 68.81 µm and met the average particle size of commercial konjac powder. The colour  L* and degree of whiteness (DoW) of porang powder decreased linearly as a function of the increasing porang flour mass, while the a* and b* values increased logarithmically, with R2 values more than 0.99.

Abstract

Bioplastics are environmentally friendly materials that serve as alternatives to synthetic plastics, capable of being decomposed by microorganisms. Starch, commonly sourced from tubers such as canna tubers, is one of the primary natural components used in bioplastic production. This study utilized a completely randomized factorial design with glycerol as a plasticizer and cellulose acetate from Oil Palm Empty Fruit Bunches (OPEFB) as a reinforcement agent. Glycerol was varied at concentrations of 1, 2, 3, 4, and 5 ml, while cellulose acetate OPEFB was varied at 1, 1.5, 2, 2.5, and 3 g. The resulting bioplastics underwent mechanical testing, including tensile strength, elongation, elasticity, water absorption, solubility, and biodegradability. The highest tensile strength (20.56 MPa) was observed with 2 ml glycerol and 1.5 g cellulose acetate OPEFB. The best elongation (33.33%) occurred with 4 ml glycerol and 1 g cellulose acetate OPEFB. Maximum elasticity (2.86 MPa) was achieved with 2 ml glycerol and 2.5 g cellulose acetate OPEFB. Optimal water absorption (12.54%) was recorded with 1 ml glycerol and 1 g cellulose acetate OPEFB, while the highest solubility (43.97%) was observed with 5 ml glycerol and 3 g cellulose acetate OPEFB. The greatest biodegradability (88.75%) was achieved with 5 ml glycerol and 1.5 g cellulose acetate OPEFB. These findings highlight the potential of starch-based bioplastics reinforced with cellulose acetate OPEFB to achieve desirable mechanical and environmental performance characteristics.

Abstract

As a traditional medicinal plant rich in flavonoids, Dayak onion (Eleutherine bulbosa) has great potential as a functional food. However, its high water content requires a proper drying process to maintain its bioactive compounds. This study evaluated the effects of oven drying temperatures 40°C, 50°C, and 60°C on the total flavonoid content (TFC), quercetin levels, and antioxidant activity of Dayak onion. Samples were dried to a target moisture content of 12% and analyzed using UV-Vis spectrophotometry, HPLC, and the DPPH method. The results showed a positive linear relationship between drying temperature and phytochemical quality. 60°C was the most effective condition, increasing TFC from 45.05 mg/L to 101.42 mg/L (2.25-fold), quercetin levels from 9.13 ppm to 17.51 ppm (1.91-fold), and significantly increasing antioxidant activity (decrease in IC₅₀ value). Thus, controlled drying at 60°C is an effective method to improve the quality and functional value of Dayak onions.
