Abstract

The application of innovation and technology in agricultural machinery in the world is one of the factors in increasing production and productivity of agricultural products. One of them is the application of agricultural machinery, namely the process of planting on agricultural land. The use of agricultural machinery at the farm level, especially planting, is still rarely carried out, as long as the availability of agricultural labor is decreasing. Most agricultural workers have entered non-productive age, while the interest of the younger generation to enter the world of agriculture is getting lower, especially conventional agriculture. Agricultural mechanization can solve this problem. The purpose of this research is to produce the performance of the seed planter in lowland rice fields. The research method uses an agrotechnical study that measures the theoretical capacity (Kt), actual working capacity (Ka), the efficiency of the seed planter's performance, and wheel slip on the seed planter.

Abstract

Coppeng is the term given by the Bugis/Makassar people to define Java Plum fruit. This fruit is a seasonal fruit that is rich in antioxidants because it contains high levels of vitamin C and anthocyanins. Due to the high antioxidant content of the java plum fruit, this fruit has many benefits that are good for health, but it turns out that this fruit is not liked by the public because of its sour and astringent taste and its properties that cannot be found all year round in the market. One of the efforts to increase the utilization of java plum fruit can be done by processing this fruit into other processed products such as functional drinks, but it is necessary to do research first regarding the determination of the formulation between the comparison of the use of java plum fruit juice, water and sweetener (fructose/sucrose). Java Plum juice was made by mixing pure fruit juice and water in a ratio of 40:60, 50:50, and 60:40, then adding 15% sweetener according to treatment (fructose/sucrose). Java plum drinks that have been prepared are tested chemically including testing for total acid, vitamin C content, pH, anthocyanin content, and antioxidants, and also through organoleptic testing including taste, aroma, and color of java plum juice. The results of the chemical analysis showed that fruit drinks with a ratio of pure fruit juice and water 60:40 and using sucrose had the highest total anthocyanins compared to other treatments. Fruit juice with a ratio of pure fruit juice and water 60:40 with the addition of fructose had the highest vitamin C content and total acid compared to other treatments, so this also caused this treatment to have the smallest pH value. The results of the organoleptic analysis showed that the ratio of pure fruit juice and water of 50:50 with the addition of sucrose was the most preferred by the panelists in terms of taste, while the ratio of 60:40 with the addition of fructose was preferred by the panelists in terms of color and aroma.

Abstract

The fluidized coffee roaster is one of roasters which designed to overcome the weaknesses of the conventional roasting method. The purpose of this research is to develop a fluidization type roaster with a Fuzzy Logic control system. The specification of the roaster are roasting chamber dimensions of 65 mm (diameter) and 75 mm (height), a roasting capacity of 40 grams with a roasting time of 300 seconds. A heater with a power of 1,200 W was used as the source of heating energy. The research method was carried out by first, developed a control program and applied to the roaster. Then, a test of functionality and performance was conducted by using Robusta coffee for a temperature set point of 190°C, 200°C, and 210°C. The performance test of control responses resulted in 6.25°C (2,97%) error steady state for 15 seconds. However, this value remains below the tolerance threshold of 5%. The test of the color quality of coffee roasted at 190°C produced 3 groups of coffee colors, namely light brown-yellow, light brown-half-city, and light brown-cinnamon. In the case of roasting temperature of 200°C, it produced 3 color groups, i.e. light brown-city, light brown-full city, and light brown-full city+. For a roasting temperature of 210°C, there were two types of colors, namely dark brown-Vienna and dark brown-Italian. It can be concluded that a fluidized coffee roaster with a fuzzy logic control system was able to produce roast coffee compatible to the target roast profile according to the National Coffee Association (2002), namely light, medium, and dark.

Abstract

Nitrogen (N) is one of the essential nutrients needed for the growth of rice plants. Therefore, N fertilizing must be applied efficiently to achieve optimal results. Various methods have been used to calculate the N content in rice plants, such as tissue analysis and the use of Soil Plant Analysis Development (SPAD) technology. This technology still has lack of time efficiency. Other technologies are needed to quickly support precise agricultural analysis, such as Unmanned Aerial Vehicles (UAV). This study aimed to analyze the N content of rice crop using the UAV-based vegetation index and to compare the measurement of N content accuracy between SPAD chlorophyll and rice plant vegetation index. This study used survey methods and laboratory tests based on several approaches, namely analysis of photosynthesis physiology, leaves tissue analysis, and vegetation index using UAV. Based on the research results, it was found that the Normalized Difference Vegetation Index value had a strong correlation with N content of leaves tissue ​​and SPAD chlorophyll. While the results of the accuracy test, the results of chlorophyll with SPAD (CI A) have better accuracy than the NDVI vegetation index. The r value between CI A – N leaves and NDVI – N leaves did not show a significant difference. In addition, the correlation results show that N content of leaves (r=0.83), CI A (r=0.88), CI B (r=81), and CI TOT (r=0.87) have a very high correlation with NDVI. This shows a unidirectional relationship between variables so that the NDVI variable can be used as a consideration to determine chlorophyll in the plants studied.

Abstract

Indonesian government is trying to increase the production of agricultural commodities in order to support the food self-sufficiency program. To support this program, the availability of irrigation facilities is important in supporting the productivity of agricultural field. Climate change and changes in agricultural systems have an impact on changes in the need of irrigation water in crop cultivation. The decreasing availability of water for agriculture encourages us to be able to use water more efficiently, especially for irrigation water. The purpose of this research is to predict the ETp value as a basis for determining plant water requirements, to determine the most suitable ETp model, to validate the prediction results of ETp values ​​using direct measurements in the field, and to obtain information related to climate factors that have the most influence on the ETp rate. The measurement of the ETp value is based on the use of Merra-2 global climate data and climate data from field measurements. ETp models used are Blaney-Criddle, Hargraves, Remanenko, Penman and Penman-Monteith. Research results showed that the ETp rate in Wajo District tended to increase during the July-October period indicating an increase in water demand in crop cultivation. The most influential climate parameter in determining the Penman Monteith ETp rate is solar radiation. The results of the ETp analysis using global data show that the Penman model is the closest model to the Penman Monteith ETp model from field measurements.

Abstract

The drying method used can affect the drying characteristics and quality of the final product such as color parameters. The purpose of this research is to study the kinetics of Z. spina-christi leaves drying, find a mathematical model that best fits the drying characteristics, and analyze the color change of dried Z. spina-christi leaves and their brew. The drying process is carried out with 2 treatments, namely using a solar dryer and by drying in an open space using direct sunlight. There are 13 mathematical models of thin layer drying selected to simulate the drying characteristics of Z. spina-christi leaves. Identification of the Lab* value is used to calculate the browning index of the leaves due to the drying method used. The results stated that the solar power dryer could increase the drying rate of Z. spina-christi leaves, thus shortening the drying time. The Diffuision Approach model is the most accurate mathematical model in describing the drying characteristics of Z. spina-christi leaves for the two drying methods tested based on the resulting constant values. Each drying method affects the browning reaction of the dried Z. spina-christi leaves which also has an impact on the color of the brew, where drying in direct sunlight will produce a darker color of the dried leaves and brew.

Abstract

Temperature and humidity conditions in plant growth are one of the important factors. Instability of temperature and humidity is often a problem that makes plants grow not optimally. The use of a green house is one way to artificially maintain temperature and humidity, but it still experiences several problems due to unstable weather conditions that affect conditions in the green house space. The control system uses temperature and humidity sensors (DHT 22) to measure the conditions in the green house space which can be used to maintain the stability of temperature and humidity in the green house. This control system will be connected to a water pump connected to a misting device where the water vapor produced by the misting is expected to be able to maintain the humidity in the green house room, and the control device will be connected to a fan which is expected to be able to maintain the temperature conditions in the green house room. The measurement data of the control system tool using the DHT 22 sensor will be compared with the hygrometer measurement data for the calibration process. Testing the function of the control device is carried out by looking at the response of the fan and pump to the setting point on the DHT 22 sensor reading. This control system is very important to apply because it can become the basis for developing greenhouses in the future, and as a basis for developing several control systems related to plant growth. The calibration results for the DHT 22 sensor and hygrometer readings obtained an error value of 0.27 °C for the temperature sensor and 1.23% for the humidity sensor. This value indicates that the sensor reading error is within the temperature sensor tolerance standard, which is ±0.5 °C and the humidity sensor tolerance is ±5%. For the results of testing the response of the pump and fan to the setting point, it shows that the two tools work well. So that it can be concluded that the design of the tool can function properly in controlling the green house space to maintain temperature and humidity stability.
