Abstract

In Indonesia, vermicelli is usually produced using arenga starch. But the arenga starch has limited in the term of quantity and the nutritional quality. In order to improve the arenga starch vermicelli, the formulation was combined with rice flour and sorghum. Each single change in vermicelli formulation will be modifies the final product color. This research studied the effect of vermicelli formulation on the color change of dry vermicelli. During the production of vermicelli, arenga starch was mixed with 10-90% of rice flour. The color parameter was observed as L* (lightness), a* (redness and greenness), and b* (yellowness and blueness). The total color difference was also calculated. The procedure was repeated with addition of sorghum. Result showed that the addition of rice flour increased the L* value. Meanwhile, the addition of sorghum decreased the L* value. Total color difference was higher in addition of sorghum.

Abstract

This research studied the effect of drying temperature on the kinetic of degradation anthocyanin in roselle extract drying with foam under dehumidified air at temperatures ranging 40-60 oC.  During the drying process, the anthocyanin content in the roselle extract was observed every 20 minutes for 120 minutes. The data was used for estimating the kinetic parameters of anthocyanin degradation namely constant of anthocyanins degradation rate and reaction order. The kinetic parameters were estimated and fitted with experimental data at various drying condition. Result showed that the anthocyanins degradation closed to the second order reaction. Meanwhile, the constant of anthocyanins degradation rate at various drying temperatures followed Arhenius correlation. With the result, retention of anthocyanin during the drying can be well estimated for various drying time and temperature.

Abstract

This research aimed at determining the optimum value between calcination temperature (X1), calcination time (X2) and %wt KF (X3) toward optimum basicity of KF/Ca-MgO catalyst. Approximately 2-4%wt KF was added to the KF/Ca-MgO catalyst using the impregnation method to assist the Ca-MgO, at 450-550 ºC and a calcination time of 2-4 hours. Furthermore, its basicity was analyzed using Tanabe's titration method. The use of Variance Analysis (ANOVA), indicated that calcination temperature (X1) factor achieved the highest basicity of KF/Ca-MgO catalyst, as indicated by its high F-value (16.46262) and low p-value (0.0067). The correlation between each operating variables and the responses were shown in a mathematical equation. The optimization value is estimated by limiting the calcination temperature from 415.9 to 584.1 ºC, with a calcination time ranging from 1.32 to 4.68 hours, and %wt KF of 1.3182 to 4.6818 % that obtained 1.18 mmol/g for the optimal catalyst basicity.

Abstract

This study introduces the innovative use of synthetic zeolite adsorbents in biomass-powered fixed bed dryers for enhanced paddy drying. The novel integration significantly improves moisture removal and energy efficiency, addressing limitations of conventional drying methods. Key findings include an effective moisture diffusivity of 2.24 × 10?? m²/s and energy efficiency reaching up to 68%. The economic analysis highlights an Internal Rate of Return (IRR) within 2.04 years, confirming the financial viability of this technology. This advanced drying system demonstrates superior performance and sustainability, offering a promising solution for industrial-scale paddy drying.

Abstract:. The uncomfortable thermal conditions in the building are complained of by the inhabitants due to the inappropriate selection of roofing materials, thus making the building unable to achieve the expected thermal conditions. Selection of appropriate roofing material will help in air cooling process and minimize energy use for cooling space. This study was conducted to determine the thermal conditions of roof space generated from various types of roofing materials that have been determined. The study object of this study is the roof space in residential buildings with a saddle roof shape with a slope of 30O roof angle. Roofing material is tile, asbestos and zinc. The results data show that the average thermal spaces of roof space on tile roofs are 1.91OC-2.31OC lower than the asbestos roof and zinc. Roof tile is also more able to withstand the sun's heat radiation. The average surface tile roof temperature is 0.28˚C lower than the surface temperature of the asbestos roof and 1.55˚C lower than the zinc roof surface temperature. However, the average profile of the lowest roof surface temperature during the daytime is on the asbestos roof (38.71˚C). Keyword: Roofing material, Thermal condition, Roof room Abstrak: Kondisi termal yang tidak nyaman pada bangunan banyak dikeluhkan oleh penghuni karena pemilihan material atap yang tidak sesuai, sehingga menjadikan bangunan tidak dapat mencapai kondisi termal yang diharapkan. Pemilihan material penutup atap yang tepat akan membantu di dalam proses pendinginan udara serta meminimalisir penggunaan energi untuk pendinginan ruang. Penelitian ini dilakukan untuk mengetahui kondisi termal ruang atap yang dihasilkan dari berbagai jenis bahan material atap yang sudah ditentukan. Objek studi dari penelitian ini adalah ruang atap pada bangunan rumah tinggal dengan bentuk atap pelana dengan kemiringan sudut atap 30O. Bahan penutup atap adalah genteng, asbes dan seng. Data hasil penelitian menunjukkan bahwa rata-rata termal ruang atap pada atap genteng lebih rendah 1.91OC-2.31OC dari atap asbes dan seng. Atap genteng juga lebih dapat menahan radiasi panas matahari. Rata-rata nilai temperatur permukaan atap genteng lebih rendah 0.28˚C dari temperatur permukaan atap asbes dan 1.55˚C lebih rendah dari temperature permukaan atap seng. Namun rata-rata profil temperatur permukaan atap terendah saat siang hari adalah pada atap asbes  (38.71˚C).Kata Kunci: Bahan penutup atap, Kondisi termal, Ruang atap
