“…In the fabricated machine, the rate at which shrinkage occurred was lowest in the electrical segment (about 24%-60%) and moderately higher for the charcoal segment (about 25%-82%). The trend obtained for moisture loss and shrinkage of suya conforms to those reported for other studies as a higher quantity of heat generated from the heat source, resulted in a faster evaporation rate which ended up in increased smoking rate (Davies & Davies, 2009;Khoshmanesh, 2006;Zeleke & Sameer, 2018…”

The grilling process of beef suya in a dual powered barbecue machine (DPBM) was modeled, optimized, and compared with conventional barbecue setup (CBS). Three‐level factorial design of response surface methodology was used as a statistical indicator with grilling temperatures (100–140°C) and meat volumes (8–27 cm3) serving as independent variables. The moisture content of suya dropped from 73% to values ranging from 11.6% to 38.48% (wb) with the grilling duration going from 13.70 to 28 min. The overall acceptability ranged from 32.5% to 94.4%, while the shrinkage ranged from 24% to 89%. The results showed temperature, meat volume, and roasting method as significant (p < .05) in modeling suya grilling. Optimum grilling in the electrical and charcoal segments of dual‐powered barbecue machine occurred at a roasting temperature of 100 and 111.44°C, respectively; volume of 26.48 and 25.95 cm3, respectively, while the temperature of 100°C and volume of 27 cm3 were optimum for CBS. Practical applications Suya is beginning to gain grounds in the international market, as there was excess demand for kilichi (dried suya) over its supply in 2018. Currently, about 18% of suya produced in Nigeria is now exported, and this has contributed to economic growth. Despite the potential of suya in boosting the nation's gross domestic product, little or no attention has been paid to improving and standardizing its production. Several suya vendors still make use of the unhygienic and energy inefficient conventional barbecues that can hardly meet up to the required demand. In addressing some of these problems, a low‐cost novel design was developed; the study investigated the optimum grilling performance of the newly developed barbecue relative to the conventional setup. The study will help improve suya production in Nigeria and as well ensure the energy economy in suya processing.

“…This drop may be attributed to osmotic dehydration of the tissue (Idah & Nwankwo, 2013;Zeleke & Sameer, 2018). The moisture content after roasting was completed ranged from 11.60% to 38.48% w.b.…”

“…This heat will be delivered to the food through a pan placed above the metal plate collector. Combining these three heat transfer combinations will increase the cooking process efficiency with a solar cooker [2][3][4][5][6][7]. Geometry types and designs of solar cookers are, in principle, classified into three types, namely (1) concentrator type, (2) box-type designs, and (3) indirect types.…”

Energy-saving technologies and equipment 31 in Indonesia comes from fossil energy sources. Until 2019, power plants in the country are still dominant from conventional energy sources, including coal (50 %), followed by natural gas (29 %), fuel (7 %). While the use of renewable energy is only about 14 %, and for solar energy, utilization is less than 1 % [1]. Currently, the largest energy user in Indonesia is the industrial sector by 36 %, the transportation sector by 40 %, the household sector by 16 %, and the commercial sector by 6 %. 1. Introduction Solar thermal energy is one of the potential energy to be managed and developed further as a source of energy reserves, especially for countries located on the equator, including Indonesia, where the sun shines throughout the year. The potential of solar power in this region can reach 5.1 kWh/m 2 /day (Eastern Indonesia) and 4.5 kWh/m 2 /day (Western Indonesia). However, the majority of energy use

“…Solar energy as a source of cooking energy is a feasible alternative to the traditional fuels of wood, kerosene, and other types of fuel [ 7 ]. Even though, solar cookers could not completely eliminate the usage of conventional fuels, they have been shown to be an effective mitigating tool to fight against global warming, deforestation, and the economic degradation of the lower income community [ 8 ].…”
