Abstract

Freeze vacuum drying is one of the best drying methods for preserving foodstuffs. Besides being one of the solutions for post-harvest technology, freeze vacuum drying is also able to increase the selling value of an ingredient. This research is a follow-up study of freeze vacuum drying where in previous studies it was found that the maximum water loss is 78% of the mass of 50 g yam with the drying chamber temperature kept at -9ºC within 4 hours, using a quick-drying method that utilizes heat from the condenser for secondary drying. In this case, the condenser will be cooled using water, the heat from condenser will be discharged and will be absorbed by water, the water will be flowed into the drying chamber, with the temperature of the water flowing at 40ºC. This study aims to develop a freeze vacuum drying method using self-heating system by utilizing heat condenser. The maximum water loss in this study was 77.2% of 1 kg mass at a constant temperature of -6ºC for 4 hours, with the energy consumption used 4.73 kWh. Keyword: Freeze, Vacuum, Drying, Yam.

Abstract

The process of distributing blood from proper storage before transfusion requires a cooling unit that is able to maintain the temperature so that the blood can be maintained and not damaged before being transfused. To maintain the chemical and structural composition of blood, it is done by storing it at a temperature of 2-6 °C and the distribution is carried at a temperature of 2-10 °C with a maximum transit time of 24 hours specifically for whole blood. To answer this problem, this research will test the ability of a box that is used as a container for the blood distribution process using a thermoelectric cooling system. Thermoelectric was chosen for use as a cooler in the blood carrier box because of its small shape so that it can be operated in a limited space and operates at a DC voltage of 12 volts. Thermoelectric uses a Peltier element with type TEC1 12706 with the coefficient of performance (COP) value based on the highest calculation result of 0.173. In the test, the input voltage variations were 9 volts and 12 volts where the blood carrier box was able to maintain the blood temperature at 4-5 °C. So that this initial research can conclude that this blood carrier box can be used to distribute whole blood. Keywords: Blood Carrier Box, Thermoelectric Cooler, Coefficient of Peformance

Abstract

The condition of electricity in Pekanbaru is really apprehensive, there are still many people who have not been supplied with electricity around the area. Wind energy as a renewable energy source has great potential to overcome the problem of electricity dependence. The relatively low wind speed conditions can be used efficiently by designing blades that are suitable for the wind speed in Pekanbaru area. The blades are designed using aerodynamic equations with software such as Q-Blade and Microsoft excel to determine blade geometry, as well as Autodesk Inventor 2013 to perform blade modeling. As a result, the blade that is designed has a tough structure and can produce mechanical power at low wind speeds with a blade radius of 1.3 m and a root chord length of 0.17 m and a chord length at the end of 0.34 m with a torsion angle at the base is 23.9 ° and the torsion angle is 7.3 ° at the ends of the blade. Keywords: Blades, Chords,Inverse Taper, Wind Turbines.

Abstract

The vaccination program is targeted to last until March 2022. Based on vaccination targets, the widely used vaccine is a vaccine with a distribution temperature of 2-8 ° C of 276.5 million. The thing that really needs to be observed is how to distribute the covid-19 vaccine from one place to another that is able to keep the temperature so that the vaccine can be maintained and not damaged before vaccination. From this problem one solution to distribute the covid-19 vaccine at a distribution temperature of 2-8 ° C with a cooling box using an environmentally friendly cooling system and has low power, one of which is adding Heat pipe and Thermoelectric Cooler, which can maintain the temperature of the vaccine. Heat pipe used by cooper as heat absorption, while in Thermoelectric Cooler type TEC2-25408 which can later maintain the temperature of the distribution of the covid-19 vaccine 2-8 ° C. Based on the calculation of the highest COP is 0.354. After testing, the Vaccine Covid-19 Carrier Box with Thermoelectric Cooler and Heat pipe that is run can maintain the vaccine temperature of 2-8 °C.Keywords : Vaccine covid-19 carrier box, thermoelectric cooler, heat pipe, coefficient of performace (COP)

Abstract

Efforts to increase the use of new and renewable energy continue to be carried out where the one of the programs is to seek the use of mixed fuels (co firing) in fossil fuel power plants such as steam power plant. The main fuel in steam power plant mostly uses coal and the mixed fuel can be used as biomass fuel. Palm oil empty fruit bunches are one of the potentially large biomass that can be used as mixed fuel because of its abundant availability, especially in Riau Province. However, palm oil empty fruit bunches have a low heating value of combustion, so the treatment needs to be carried out in order to palm oil empty fruit bunches as biomass fuel have a high heating value. This study aims to increase the heating value of palm oil empty fruit bunches by torrefaction process so that palm oil empty fruit bunches have a high heating value and equivalent to the heating value of coal. The torrefaction process is carried out with variations in time and temperature of torrefaction, namely 30 - 60 minutes and 200oC - 300oC. The research carried out results in the largest heating value of 7470.59 kcal/kg at a time process of 60 minutes and a torrefaction temperature of 300oC.

Abstract

Banyak usaha yang telah  dilakukan dalam pengefisienan energi pada pembangkit listrik. Salah satu cara untuk meningkatkan efisiensi penggunaan energi adalah dengan melakukan analisis. Analisis yang dimaksud disini adalah analisis exergy. Konsep analisis ini, tidak hanya memperhitungkan kuantitas energi tetapi juga kualitas energi (hukum kedua thermodinamika). Analisis Eksergi dilakukan dengan mengambil sampel pembangkit listrik turbin gas Teluk Lembu berkapasitas 21,6 MW. Tujuan dari penelitian ini adalah untuk menganalisis dan mengetahui lokasi dan besar kehilangan exergy. Hasil penelitian menunjukkan bahwa pemusnahan eksergi paling besar terjadi di ruang bakar mencapai 21,85 MW dan sementara turbin gas terendah 3,09 MW. Dan efisiensi ekserginya didapat 22,73%. Berdasarkan perhitungan, analisis eksergi dapat menentukan besarnya, lokasi pemusnahan eksergi. Ini akan membuatnya lebih mudah untuk melakukan optimasi untuk meningkatkan efisiensi.
