Abstract

One of the basic needs, especially for the people of Indonesia, is rice. This causes the demand for rice to increase day by day in accordance with population growth. Therefore, rice production in Indonesia is expected to meet the basic needs of the Indonesian population. Estimating the level of rice production is important to determine the level of food availability in an area. Image data obtained from drones and sentinel images can be analyzed to obtain vegetation indices and used to predict rice production. The purpose of this research is to see the relationship between the RGB vegetation index of drone imagery and the NIR-based index of sentinel imagery with rice production. in this study, a regression analysis was conducted between the vegetation index values ​​obtained from drone imagery and sentinel-2 imagery with rice paddy production then the equation obtained from the regression analysis was used to estimate rice paddy production on the rice fields used as test samples. Correlation analysis was also conducted where this analysis was used to see how strong the relationship is between the vegetation index used and rice production. As for the results obtained, there are three levels of relationship obtained from the results of correlation analysis between several vegetation indices used, namely strong, medium and very strong levels. The TGI vegetation index shows a moderate level of relationship, while the strong level consists of the VARI, ExG, RGBVI and GLI vegetation indices. And at a very strong level shown by the NGRI, NDVI and NDRE vegetation indices. Estimation of rice production can be predicted with the NDRE vegetation index which has the highest determinant value, which is 84.06%. Validation of the NDRE vegetation index shows a result of 55.97%, where more data is under estimate which means the estimation results are smaller than the results obtained in the field.

Abstract

Disasters for plantjs usually occur due to the incompatibility of the environmental temperature with the temperature limit for plant growth, one example is the pakcoy plant which requires exposure to direct light with the air temperature not being too hot. Evaporative cooling is one of the methods to reduce temperature and increase relative humiditygreenhouse to create optimal climatic conditions for plants. One way of evaporative cooling is done by using a toolmisting (atomizer). This study aims to determine the effectiveness of usemisting in microclimate control (temperature and humidity). Greenhouse on the growth of pakcoy plants. This study used the method of direct observation which was carried out during the planting period of pakcoy plants. Based on the results obtained, the lowest average temperature was in the 30 minutes misting of 27–30 °C, at misting 20 minutes 27–31 °C, meanwhile misting for 10 minutes 27–31 °C and withoutmisting ranges from 32–38 °C. Air humidity on misting 30 and 20 minutes between 81–89 % and treatment misting 10 minutes ranged from 82–89%, while at without misting ranging from 63–77%. The use of misting as an effective control of temperature and humidity produces an average air temperature and relative humidity for the growth of pakcoy plants, namely a temperature of 26-31 °C and a humidity of 82-89%. The misting treatment with an interval of 20 minutes produced the highest number of leaves, namely 22 leaves and the misting treatment with an interval of 10 minutes produced the plants with the highest plant height and weight. The use of misting ignition time intervals has a significant effect on temperature but does not have a significant effect on humidity.

Abstract

One application of technology in agriculture is the use of water pumping machines to provide water for plants. Various innovations have been made to reduce the operating costs of water pumps, one example is to use Liquifield Petroleum Gas (LPG) to replace gasoline fuel. This study aims to compare the performance and efficiency of gasoline-fueled (BBM) and gas-fueled (BBG) pumps. This study uses several observation parameters including, calculating water discharge, analyzing gasoline and gas fuel requirements, calculating the power generated by the pump when raising water, and calculating engine torque. The results showed that the water discharge obtained for the fuel engine was 0.002808 m3 / second while for the gasoline engine it was 0.002961 m3 / second. The cost required for the operation of the BBM pump engine is Rp.23,615 / hour, while for BBG it is Rp.11,920 / hour. For the power generated by the BBM engine, it produces a power of 80.808 W, while for the BBG engine it produces a power of 83.882 W. The water pump engine in this study operates at a torque of 7.84 Nm. Based on the results of this study, it can be concluded that the use of LPG gas fuel in the rice field water pump engine is more efficient and the water discharge produced is also more than the fuel water pump.

Abstract

Dragon fruit is one of the fruits with a fairly high water content which causes an increase in water activity and accelerates the growth rate of microorganisms. research was conducted to determine the shrinkage that occurs in the fruit. Two different sample sizes were used in this study. Both were cylindrical in shape with a diameter of 2.5 cm and different lengths. 3 cm (Sample A) and 1.5 cm (Sample D). The number of samples used for sample A and sample D was 5 pieces each. Measurements of weight and dimensions (sample length and diameter) were repeated every 15 minutes during the drying time at 45 ºC. Once the sample weight was constant, the material was put back into the oven at 105 ºC for 72 hours. After 72 hours, the sample was weighed and measured to determine the dry weight of the sample. Based on the study of the pattern of changes in the dimensions of red dragon fruit during the drying process, it can be concluded that the pattern of changes in volume ratio to KAbb is a linear pattern with an R2 value of 0.9946. The pattern of changes in volume ratio to KAbb is polynomial degree 2 and 3, but the R2 value is greater for degree 3, so degree 3 is more suitable for estimating the volume ratio of KAbb.values.

Abstract

Cherry tomatoes have a fairly short shelf life due to the influence of high water content and enzymes present in the fruit. Blanching is used to inactivate enzymes that can damage the quality of tomatoes. This research was conducted with the aim of studying the effect of blanching on the drying rate and sorption isotherm of cherry tomatoes. Blanching was done at 60 °C, 70 °C, 80 °C. After blanching, the samples were dried at 60 °C. After drying the samples were stored in a desiccator containing a solution for 24 days using NaOH, MgCl2, K2CO3, NaNO2, and NaCl. The results obtained in the blanching process have a lighter color than before blanching based on the L.a.b value. The moisture content of the sample during drying can be seen from the MR and drying rate which have almost the same value, only the time to reach 12% moisture content is different. The sorption isotherm process in the control treatment, blanching with temperatures of 60 °C, 70 °C and 80 °C with time (15, 30 and 45 minutes) experiences two processes, namely desorption (water release) at low RH and absorption (water binding) which occurs at high RH. The conclusion obtained is that the sorption process only occurs at 60 °C blanching with a time of 15 minutes at low RH and other treatments experience desorption.

Abstract

Statistical data shows that rice production increases every period along with the increase in demand. Harvested paddy must be dried immediately to avoid damage due to microbial attack that can live in high moisture content. Therefore, the main objective of drying is to reduce the moisture content from the harvest moisture content (23-27%) to a safe moisture content for storage (14%). Currently, there are several dryers made as a solution in post-harvest handling of grains such as green beans, soybeans, grain and so on. One example of this dryer is the Fluidized Bed Dryer. This tool is a mechanical dryer that can be used in drying grain. The advantage of this tool is that the temperature can be controlled and can produce quality and uniform drying results. The purpose of this study was to determine the drying characteristics of Inpari 42 grain using a fluidized bed dryer. This research method uses speed variations of 1.5 m/s, 2.0 m/s, and 2.5 m/s with sample masses of 200 g, 250 g and 300 g, using a temperature of 55 ℃. The research parameters include moisture content, drying rate, damaged grain. The drying process shows that the change in sample mass is influenced by the air velocity used. Along with the increase in moisture content, the drying rate will affect the rate of drying obtained in this study the drying rate pattern is decreasing. It can be concluded that air velocity affects the drying rate and air velocity affects the cracked grain.
