Abstract

Siomay is a product made from fresh mackerel fish made by steaming. However, dumplings have a relatively short shelf life. Syrup has a relatively short shelf life at room temperature. Generally the non-vacuum dumplings save only lasts 2 days. The need for natural preservatives is safe to consume to increase the shelf life of the dumplings. Generally, foods containing protein elements when decaying the levels of protein contained in food will decrease. The technology commonly used is liquid smoke. But the problem In addition to the content of phenolic compounds liquid smoke is easily damaged (oxidation) during storage. Handling of liquid smoke requires the development of technology by converting liquid smoke into flour or powder, which is through nanoencapsulation technology so that it will increase the shelf life of food products. Based on the results of the research that has been done is the quality of the smoke flour contains a percentage of phenol content of 3.15%, while in the dumplings dumplings which have added smoke flour 5% the percentage of phenol content is 1.80%. In the dumplings which are added with smoke flour 10% the percentage of phenol content is 2.24%. Three-day observations carried out on decreasing levels of siomay protein added with 5% smoked flour showed a decrease in protein content of 0.98%, while those in smoke dumplings added by 10% decreased the protein content by 0.74%. From the observation of siomay given with smoked flour with non-smoked flour showed that simay dough can last more than three days. Optimization of adding smoked flour which is good for maintaining protein content is 10%.

Abstract

Siomay is a product made from fish made by steaming. However, dumpling have a relatively short shelf life at room temperature. This is because siomay has a high water content and water activity (aw). The need for natural preservatives is safe to consume to increase the shelf life of the dumplings. The technology used is liquid smoke. Volatile compounds in liquid smoke that play a role in bioreservative activity can evaporate during storage. So that technology development is needed to protect the active component by turning it into liquid smoke flour. Liquid smoke flour also has a higher phenol component compared to liquid smoke. The purpose of this study was to determine the optimal maltodextrin concentration and storage time in making nano-particles on siomay quality. The results of this study indicate that the content of liquid smoke is eliminated maltodectrin has titrated total acid from liquid smoke flour concentrated at 20%, 30%, 40% and liquid smoke is 1.024%; 0.832%; 0.896%; 2.495%. Water content of liquid smoke flour concentration of 20%, 30% and 40% is 9.436%; 7.186%; 8,333%.The optimum acidity level of siomay for maltodectrin concentration is 20%, 30%, 40% is 0.820%; 0.882%; 1.013% and optimum protein content in siomay from maltodectrin concentration of 20%, 30%, 40% is 3.95%; 3.98%;4.20%

Abstract

Cooking oil is one of the nine basic human needs in meeting daily needs. Repeated use of manufacturer cooking oil with high heating can cause oxidation in the oil which can cause the oil composition to change and produce compounds that have a rancid odor. This study aims to determine the optimal amount of frying in the manufacturer's cooking oil that has been added with liquid smoke for tofu frying. The liquid smoke of rice husk is obtained from the process of pyrolysis of rice husk which contains components of cellulose, hemicellulose, and lignin which produce phenol compounds, acid compounds and their derivatives, which can be used as antioxidants to prevent rancidity in the manufacturer's cooking oil. The parameters used in the analysis of the quality of the manufacturer's cooking oil are tests of free fatty acid levels, acid numbers, and peroxide numbers. The results showed that cooking oil was still suitable for use until the fourth frying time. The most effective volume of liquid smoke was 27 ml.

Abstract

Soursop leaf (Annonamuricata L) is a fruit plant originating from the Caribbean, Central America, and South America. In soursop leaves, there are flavonoid compounds, namely phenol compounds with antioxidant, antibacterial, antiviral, anti-inflammatory, anti-allergic, and anticancer activities. The capture of free radicals causes this compound's antioxidant effect via the hydrogen atom donor from the flavonoid hydroxyl group. Some diseases such as atherosclerosis, cancer, diabetes, parkinsonism, Alzheimer's, and decreased immunity have been affected by free radicals in the human body. Flavonoids are of concern because of their medicinal role in the prevention of cancer and cardiovascular disease. One obstacle in the use of soursop leaf extract is the inefficiency of the solvent used so far. This research uses ethanol solvent because ethanol solvent can extract soursop leaves with flavonoid levels 1.36% greater than n-hexane solvents, flavonoid content is 0.66%, and 2propanol solvent is chosen because its polarity is lower than ethanol, so it is expected to extract flavonoid levels. More optimal than ethanol. This study aims to determine the optimization of maceration time and type of solvent on the levels of flavonoids in the soursop leaf extract. This study was designed with a 2 level design factorial method, and two variables changed, namely maceration time (48, 72, 96) hours, ethanol, and 2propanol fractionation solvent types. Fixed variables used were drying time 30 minutes temperature 50oC, sample weight of soursop leaf 10 grams, extraction solvent volume 200 ml, extraction temperature 28oC (room temperature), the method used spectrophotometer. These static and changing variables have a positive effect that can increase phenol levels, and the most influential variables are the type of solvent and extraction time. The best conditions in the cytotoxic extraction process are ethanol solvent and maceration extraction time of 72 hours.

Abstract

The double pipe heat exchanger (DPHE) is one type of heat exchanger (HE) that is commonly used in industrial applications such as electricity generation, petrochemical industry, process industry, and other industries. The double pipe heat exchangers are commonly used because of low design costs and maintenance costs. The need to achieve optimal double pipe heat exchanger performance, this research will examine the optimization of double pipe heat exchanger performance by varying fluid flow velocity and adding twisted tape insert with a twist ratio (H/D) = 6 in terms of Nusselt number (Nu), friction factor (f), and effectiveness (?). The test is carried out with fluid in the form of water and fluid flow velocity variations are 2.5, 3.5, 4.5, 5.5, and 6.5 LPM. The experimental results show that the Nusselt number value and effectiveness have increased with increasing fluid flow velocity. While the friction factor value decreases with increasing fluid flow velocity. The increase in Nusselt numbers was 2.14 times and the effectiveness value was 8.69%. While the value of the friction factor decreased by 55%. The optimum fluid flow velocity obtained from the results of the study is 6.5 LPM with Nusselt number, friction factor, and effectiveness reaching 48.43; 0.27; and 0.259.

Abstract

In the implementation of the siphon system it is used to prevent failure of rising groundwater levels that flow in the highlands including mountain slopes. The siphon system experiences greater drop pressure along with the increase in the height of the siphon, which should have higher pressure with a constant flow and an increase in the height of the siphon to achieve greater siphon system efficiency. To find out the value of pressure drop and the cause of the pressure drop on the siphon system, three methods are used, namely theoretical calculation, simulation of CFD ANSYS and actual measurements using pressure gauge water of bordoun type analogous with variations of valve opening 100% full opened, 66,67% opened, and 33,33% opened and the heights of the siphon are 1 meter, 1,5 meters and 2 meters. From the results of the three methods, the average water flow rate varies based on the height of siphon 1 meter, 1,5 meters and 2 meters is 0,0000854 m3/s to 0,0002716 m3/s and the average pressure of 111.736,7 N/m2 to 88.899,57 N/m2. While the average value of siphon based on variations in valve openings with the same height of siphon is obtained 83.939,634 N/m2 to 130.400,615 N/m2. In addition, an error value between theoretical calculation and CFD simulation of 0,03% to 1,18% and error of the between theoretical calculations and actual measurements is 0,08% to 1,10%.
