Abstract

This research aims to develop and research further about the potential of wind in Jombang to be used as analternative to wind power plants by utilizing the domed swivel mosque. The method in this research is experimentalresearch related to science and engineering technology, namely the making of a mosque turning dome as an alternativeto wind power generation. This tool utilizes the spinning dome of a turning mosque as a producer of motion energywhich is connected to a dc generator using gear and chains as a transformer of rotary motion energy into electricalenergy that produces dc electricity output. The DC electricity is supplied to the Buck boost converter to be regulatedand stabilized the voltage entering the charger module to charge the battery. The output from the battery is then insertedinto a step up step down to be regulated and the voltage is stabilized to 12 v towards the volt ampere meter input as atool to read the voltage on the battery and the current on the lamp. Based on the results of this study, it can be found thatthe blow angle of the blower against the dome 30 ° to the dome is less effective, if the blow angle of the blower againstthe dome is 40 ° it has good effectiveness and greatly affects the stability and speed of the dome rotation and theincrease in load applied to the dc generator results in drop voltage so it greatly affects the supply to the battery.

Abstract

The progress of a country cannot be separated from the role of energy, because with the existence of advanced energy it will be able to accelerate the progress of the country itself, energy itself is divided into 2 namely fossil and renewable energy. One of the renewable energies is the use of geothermal energy which can be converted into electricity through the photovoltaic effect. Indonesia itself is a country that is crossed by the equator so that it gets a lot of heat supply. The use of solar panels can be applied to the Knapsack Sprayer as an effort to minimize the use of fossil energy which is used as the main energy for producing electrical energy. This research is to see the effect of the use of polycrystalline solar panels in terms of a predetermined angle of inclination. This type of research is experimental research by controlling the angle of inclination in this case 25 degrees. The measurement of this research uses a digital DC avometer with its own power supply which will display the amount of charging current for the Knapsack Sprayer battery. Prototype testing is carried out after making the prototype, the manufacture starts from installing the panel on the knapsack sprayer and being given a holder. The test was carried out in a few days, the results obtained were in the form of a large charging current in the solar panel system. The results of this measurement will be calculated using the charging time formula to find out how long it takes to charge the battery on a monocrystalline panel in terms of an angle of 25 degrees. Based on the results of the tests and calculations, the data in the form of battery charging current using polycrystalline panels at an angle of 25 degrees in the first test was 0.44 amperes, the second test was 0.43 amperes and the third test was 0.48 amperes. From the test results, it is calculated and produces an average charging value using polycrystalline solar panels for 10.6 hours.

Solar Panel technology is technology that serves to transform the energy of sunlight into electrical energy. Solar Panel is a layer of semiconductor that has a surface area of and consists of a series diode. The sun is the main source of energy that is produced solar panels. In the use of solar panels, which have a major influence is the intensity of the light of the sun (radiation), due on panel solar radiation greatly affects the size of the power obtained from the system photovoltaic. The angle of inclination of solar panels the right is very influential in order to obtain maximum power intensity of the light of the sun. Therefore this study was conducted to determine the influence of the tilt angle of the solar panel to the power output of solar panels. This study describes a result of the angle of inclination which has a result in the form of voltage, current, power and efficiency. With the aim to determine the voltage, current and power produced by the tilt angle of 10 °with respect to the output power of the solar panel.

Abstract

Turmeric is one of the most commonly encountered rhizome plants that are used for cooking because it is a natural coloring of a food. Turmeric has a water content of about 80% to 82,5%. Drying is the process of heat transfer that is done to remove the water content in an object with a medium in the form of hot air. Currently there are 2 commonly used drying methods, namely drying in a natural way that uses solar heat as its heat media and artificial drying that uses other aids as heat media. This study used this type of experimental research with variations in the degree of gas control rotation of 90°, 135°, 180° on rack-type dryers. The purpose of this study is to find out whether or not the effect of the degree of gas control spin on the water content of turmeric evaporated. The results of the study will be conducted multiple regression analysis by conducting a T test on the SPSS 26 application. Results obtained from the T test stated a significance value of 0,015 < 0,05 and a calculated T value of 3,378 > 2,447. Conclusions obtained from the results of the T test stated the effect of the degree of gas control round on the evaporated turmeric water content.

Abstract

Temulawak is a plant that is included in the category of plants that are very good for health. In its management, the community still uses natural methods such as solar heat, even though this method is less effective because the weather in Indonesia is uncertain. Therefore, there must be a new solution, one of which is to use oven drying. Oven drying is one method of drying using a temperature variation of 60°C with a time variation of 120 minutes. From the results of this study, the shrinkage value of the initial weight of the material was 400grams after the drying process was carried out, the final weight was 239.6 grams or the shrinkage was 40%. From this it can be concluded that the temperature and drying time are very influential for reducing the water content of temulawak.
