Tim pengabdian kepada masyarakat Jurusan Teknik Konversi Energi (JTKE) bersama dengan pihak Pemerintah Kota Cimahi - Dinas Perdagangan Koperasi UKM dan Perindustrian Kota Cimahi berkoordinasi dalam upaya mendukung pengembangan usaha kecil dan menengah yang berasal dari jenis kelompok usaha penyediaan makanan lainnya. Salah satu pengusaha yang termasuk dalam jenis kelompok usaha tersebut adalah produsen makanan olahan dari labu dengan nama usaha “Roemah Labu”. “Roemah Labu” telah memiliki pasar yang cukup luas serta produk yang konsisten yaitu pangsit labu dan dodol labu. Saat ini “Roemah Labu” sangat memerlukan alat pengering untuk mendukung proses produksi keripik labu (dalam tahap pengembangan) dan berbagai produk makanan olahan dari limbah bahan baku labu, yaitu kulit dan biji labu untuk menambah varian produknya. Adapun jenis pengering yang coba didiseminasikan merupakan sebuah alat pengering surya sederhana dengan tujuan untuk memperbaiki kualitas proses produksi dari segi higienitas maupun kuantitas varian produk. Alat pengering surya (Solar Dryer) dirancang agar independen dari sumber energi selain panas matahari. Alat pengering ini terdiri atas dua bagian utama, yaitu ruang pengering dengan lima susun tray berukuran 60 x 60 cm dan solar collector berukuran 1.05 x 1.3 m. Banyaknya produk labu tambahan yang dapat dihasilkan dalam satu kali produksi dari setiap kg labu, yaitu 111 gram kulit labu kering (cuaca cerah), 29 gram kulit labu kering (cuaca hujan), dan 34 gram biji labu kering/ matang.

This study is concerned with the analyses of performance on a solar dryer integrated with solid desiccant coloums using water based solar collector. The dryer consists of a solar water collector, two solid desiccant coloums, a water storage tank, two heat exchangers, an air heater, and a drying chamber. The dryer decreased the <em>Centella asiatica</em> L moisture content from 88.3% (wb) to 15.9% (wb) within 12 hours, with an average temperature and relative humidity of 45.4°C and 25.8%, respectively. The rate of moisture evaporation and the specific moisture evaporation rate were in the range of 0.001-1.762kg/h and 0.02-0.482 kg/kWh, with 0.594kg/h and 0.169kg/kWh in average values, respectively. The dryer efficiency was in the range of 0.62%-30.4%, with 15.4% in average value. The energy required for moisture evaporation and total energy input to the dryer were in the range of 26.9-1132.2W and 3638.0-4329.7W, with 601.8 W and 3967.4 W in average values, respectively. The efficiency of collector and the heat exchanger effectiveness were in the range of 38.1-50.5% and 65.1-79.7%, with 45.0% and 73.0% in average values, respectively. The result shows that the dryer is suitable for drying <em>Centella asiatica </em>L, this is due to the low temperature of drying air and high moisture evaporation rate.

A grain drying complex based on solar energy, including a grain storage with a built-in solar drying system and a drum solar dryer for grain, is proposed. The construction and principle of operation of the grain drying complex is described. The basis of each of the solar drying systems of the complex is the presence of two solar collectors, one of which provides heating of the drying agent at the inlet into the drying chamber, and the second-heating of the used drying agent in the exhaust pipe to increase its flow rate and, accordingly, the intensification of grain drying. Availability of gravel or water heat accumulators allows to carry out the process of grain drying or grain storage, at night and under adverse weather conditions without the risk of self-heating. The optimum capacity of the gravel accumulator is 0.5-0.75 m 3 per 1 m 2 of solar collector area. Drum solar dryer provides guaranteed drying of a grain batch for 6-7 hours of the day time and a grain batch for the night time. It was found that the optimum thickness of the grain layer in the drying process is 50-70 cm and specific load is up to 100 kg of grain per square meter of the horizontal solar collector area.

Abstract A work on the design, construction and computational fluid dynamics modelling of a solar dryer with a double pass solar air collector is presented. Using fundamental relationships, an indirect solar dying system for drying banana was designed and constructed. The system consists of a drying chamber and a double pass solar collector (DPSC), connected together with a flexible aluminum pipe. The system features a unique arrangement, as the drying chamber is underneath the double pass solar collector, and the solar collector itself can be adjusted to an angle of 0° up to 35° the maintenance or research purpose. The DPSC has five longitudinal fins, lying parallel with air flow. The solar dryer is incorporated with a convective DC fan that sucks hot air from the solar collector on to the drying chamber. The DPSC achieved an optimal peak outlet temperature of 345K with a maximum operational efficiency of 72.5%. A computational fluid dynamic (CFD) model is achieved for prediction of the dryer temperature and 3D airflow distribution within the dryer unit using ANSYS 18.2. The CFD model was validated using experimental data. The developed dryer demonstrated improved efficiency over similar dryers, and this is attributable to the unique arrangement of component parts.

In this paper, the performance assessment of a hybrid active greenhouse solar dryer is carried out under no load condition. The hybrid greenhouse solar dryer consists of evacuated tube solar collector and heat exchanger kept inside the dryer that also act as the drying bed. The performance of developed dryer is evaluated with and without evacuated tube solar collector. The maximum room temperature inside the dryer with collectors is found 21.4% higher than the dryer without ETC. The average temperature difference between the room and ambient air temperature for the case of dryer with collector is 16°C while in case of dryer without ETC it is 7.51°C only. Hence the developed dryer is effective for drying of high moisture crops.

This research paper presents the experimental results of drying of chili by using the active solar dryer and sun drying because of chili is a commercial agricultural product of Thailand. The active solar dryer consisted of a solar collector, a drying chamber and a chimney. The small fans were installed in the solar collector of active solar dryer to provide the air flow circulated in the solar collector and a drying chamber. Drying of chili of 20 kg from moisture content 84 percent wet basis to 10 percent wet basis following the Thai Agricultural Standard (TAS 3001-2010) showed that the use of the active solar dryer to make the drying time reduced about 28.7 percent compared with sun drying because of the hot air temperature inside the drying chamber higher than the ambient temperature about 10 to 15 . The quality of dried chili from the active solar dryer better than dried chili from sun drying.
