Abstract

Banana skins have several potential applications in the health and beauty industries. Through a fermentation process with the help of Acetobacter xylinum, it produces banana skin bacterial cellulose. It is possible to further process this cellulose into a face mask matrix. Bacterial cellulose has biodegradable properties, a low toxicity value, and a good absorption ability to be applied as a face mask matrix. The addition of serum to the mask matrix aims to focus on the function of the formulated matrix. Methods: filtering the sample; making nata de banana skin with different fermentation times; making a matrix mask; matrix mask characterization; and data analysis. The results of the study showed that the variation of different fermentation times can affect the resulting cellulose products. The optimal fermentation time for producing nata was 10 days, resulting in a thickness of 0.92 cm. Then, the evaluation tensile strength test on the mask matrix revealed the highest value was also a 10-day fermentation variation, 3.000–10.000 kg/cm2. And last, the best test of the release of vitamin C is the 10-day fermentation variation.

Abstract

Penelitian ini dilakukan di Kabupaten Natuna, dengan tujuan untuk mengetahui kesediaan membayar masyarat Kab. Natuna untuk penerapan teknologi pengolahan sampah, menghitung estimasi nilai willingness to pay (WTP) untuk mendukung penerapan teknologi pengolahan sampah di Kab. Natuna, dan mengetahui faktor-faktor yang mempengaruhi nilai WTP. Pendekatan yang digunakan adalah Contingent Valuation Method, dan untuk menguji hubungan kausal antara variabel bebas dan variabel terikat, metode regresi linear berganda digunakan. Berdasarkan hasil wawancara terhadap 50 responden diperoleh bahwa 96% responden bersedia membayar retribusi. Perkiraan besaran nilai kesediaan membayar (WTP) per KK per bulan masyarakat Kab. Natuna guna mendapatkan peningkatan pelayanan pengelolaan sampah berdasarkan setiap alternatif teknologi pengolahan adalah Sanitary Landfill sebesar Rp14.980,-; Komposting sebesar Rp.11.600-, dan Biodigester sebesar Rp15.480-,. Faktor-faktor yang berpengaruh adalah faktor sosio-ekonomi, seperti tingkat pendidikan dan pendapatan. Kedua faktor tersebut sangat berpengaruh signifikan untuk semua alternatif teknologi yang ditawarkan. Sementara faktor pengetahuan teknologi hanya berpengaruh pada teknologi Sanitary Landfill dan Komposting. Sementara itu, faktor jumlah anggota keluarga dan keyakinan terhadap teknologi tidak menunjukkan pengaruh yang berarti.

Abstract

While biomass is a promising carbon-neutral alternative to coal, the specific volatile matter (VM) flame characteristics of diverse biomass pellets, particularly water hyacinth, remain under-researched. This study uses a numerical CFD approach (Ansys Fluent) to investigate how varying VM fractions influence flame structure in a 2D planar slice of the furnace block (25 cm width). Simulations employed the SST k–ω turbulence and Eddy dissipation model to capture mixing-limited chemical reactions. Boundary conditions were based on experimental configurations using a 0.05 m/s air inlet velocity. Results using CO-based flame-tip markers revealed that water hyacinth (VM: 63.5 wt%) produced a peak temperature of ~1,400°C at 75 cm above the fuel, while rice husk and bagasse (VM: 59–77 wt%) exhibited longer, more intense hot plumes compared to the localized heat profile of coal. These findings demonstrate that biomass generates more dispersed combustion zones, aiding in furnace hot-spot prevention and air control optimization. A limitation of this study is that findings are based solely on numerical simulations without direct experimental validation, although the model replicates physical furnace configurations. These results provide a foundation for developing sustainable biomass–coal co-firing technologies.
