“…Thin‐layer drying is widely used to determine the drying kinetics of crops and has been carried out in various types of dryers (Alara, Abdurahman, Mudalip, & Olalere, ; Jiang et al, ; Lee & Kim, ). Many researchers have studied and predicted the drying behavior of a product to design a dryer using thin‐layer drying mathematical modeling (Aidani, Hadedkhodaparast, & Kashaninejad, ; Akpinar, Midilli, & Bicer, ; Asiru, Raji, Igbeka, & Elemo, ; Janjai, Intawee, Kaewkiew, Sritus, & Khamvongsa, ; Mabrouk, Benali, & Oueslati, ; Mahjoorian et al, ; Mujaffar & John, ; Naderinezhad, Etesami, Najafabady, & Falavarjani, ; Younis, Abdelkarim, & El‐Abdein, ).…”

This paper presents thin‐layer drying of parchment coffee (Coffea arabica). Thin‐layer drying of parchment coffee was conducted under controlled temperatures (50°C, 60°C, and 70°C) and relative humidities (10%–30%). The temperature of the drying air was important for drying at a high temperature, which results in the rapid removal of moisture and reduced time for drying. Nine thin‐layer drying models (Newton, Page, Henderson and Pabis, logarithmic, two‐term, modified Henderson and Pabis, two‐term exponential, approximation diffusion, and modified‐Midilli) were fitted to the experimental data for parchment coffee. The drying parameters of parchment coffee were related to temperature and relative humidity. The best model was the modified‐Midilli model, which can be used to design the optimal dryer. The effective moisture diffusivity of parchment coffee drying was determined by minimizing the sum of squares of the deviations between the experimental data for the moisture content and the predicted values of thin‐layer drying. The effective moisture diffusivity as a function of the temperature at each relative humidity was expressed by the Arrhenius‐type equation.

Abstrak Perak sulfat merupakan garam anorganik dengan rumus Ag2SO4. Perak sulfat ini termasuk dalam senyawa ionic karena terdapat ikatan antara logam perak dengan spesi non logam sulfat. Perak sulfat memiliki. berat molekul yaitu 311,799 gr/mol dengan tampilan kristal tidak berwarna dan tidak mudah terbakar. Senyawa ini digunakan dalam penyepuhan perak (silver plating) dan pengganti tanpa noda untuk perak nitrat. Perak Sulfat mengalami interaksi molekul dalam pelarut Air. Tujuan penelitian ini adalah untuk mengetahui karakteristik molekul dan transpor ion Perak Sulfat. Metode yang digunakan dalam penelitian ini adalah penelusuran literatur dengan Endnote X7, pemodelan komputasi, dan perhitungan matematis. Data transpor ion Perak Sulfat yaitu dengan parameter konduktivitas, viskositas, mobilitas ion, dan daya hanyut menggunakan data hasil review beberapa jurnal penelitian yang berkaitan dengan Perak Sulfat sesuai tahapan pada fishbone. Secara termokimia, perak sulfat memiliki entalpi pembentukan standar, ΔfHo 298 -715 kJ/mol dan entropi molar standar, So298 16,74 kJ/mol. Kelarutan Perak Sulfat dalam air yaitu 0,79 gr/100 mL (20 o C) dan dapat larut juga dalam pelarut asam nitrat. Hasil penelitian konduktivitas larutan Ag2SO4 semakin meningkat seiring dengan kenaikan konsentrasi persen massa sesuai grafik hasil perhitungan.

One of the regions that produce lemongrass oil in West Java is Gununghalu and Rongga sub-district, Bandung Barat Regency. The problem faced in citronella cultivation is uncertainty on the quality of lemongrass and simple refining technology. This research was conducted to determine lemongrass cultivation (including procurement of raw materials, post-harvest handling) and refining technology used (in the refining process) that was economically feasible. In this study, the economic feasibility of citronella cultivation and refining was measured by considering the availability of raw materials; refining facility capacity, and operational costs incurred. This paper will describe the analysis of the Net Present Value of the cultivation and refining of citronella oil. The results showed that to maximize the distillation of citronella oil, raw materials needed as much as 1800 kg for each refining process. The raw material is needed for distillation in a refinery with a capacity of 600 kg and three times a day distillation. Based on Net Present Value analysis, it can also be seen that the business of refined fragrant lemongrass oil is considered economically feasible and can provide benefits if managed properly.
