<![CDATA[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.]]>

<![CDATA[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. The angle of inclination used in this study is the slope angle of 10º. In this study, using the method of the analysis of comparative data from the test results using the tilt angle of 10º. The results obtained in the form of data using the calculation formula and the instruments of data collection. This research is to get the test results in the form of Voltage that the most optimal is produced at a slope angle of 10° on day 1 of 12.5 Volts, while on day 2 of the resulting tilt angle of 10° at 13.6 Volts, and on day 3 the resulting tilt angle of 10° by a 13.7 Volts. The current most optimal generated at a tilt angle of 10° on day 1 of 5 Amperes, while on day 2 of the resulting tilt angle of 10° at a rate of 5.2 Amperes, and on day 3 the resulting Current tilt angle of 10° by 5,65 Ampere. Power is the most optimal generated at a tilt angle of 10° on day 1 were 62.5 Watts, while on day 2 of the power generated tilt angle of 10° of 70.7 Watts, and on days 3 power produced by the tilt angle of 10° amounted to 77.4 Watt.]]>

<![CDATA[The solar Panel is an array of solar cells that can convert light energy of the sun into electricity. The intensity of the light and the power output is strongly influenced by the mounting direction of the position of the solar panel. This research has a purpose to analyze the results of the influence of the direction of the position on the power output and efficiency of solar panel module. The research method used is experimental type quantitative research methods. This method is used to determine the effect of independent variables i.e. the direction of the position on the dependent variable i.e. the power output and the efficiency of the solar panel in a state that is controlled. The results of the data obtained from measurements using the instrument of data collection and the calculation formula. This study obtained different average power output results, for the west 46.72 Watt, the north of 50,30 Watt, the east of 36,17 Watt, and the south 35,78 Watt.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>
