Prediksi Pengoperasian Traktor di Lahan Kering Menggunakan Artificial Neural Network
Get PDFSoil water content is an important parameter in making a decision to use a tractor or not. The process of measuring soil water content and levels of field capacity in conventional which takes a long time and cannot be used in real-time to measure it is a major problem in the field. Determinants of soil water content such as ambient temperature, humidity, and rainfall can be obtained easily and quickly either by using a tool or retrieving data from the nearest BMKG station. The objective of this research is to obtain the most optimal prediction model in making decisions about tractor operation in dry land. This research uses an Artificial Neural Network (ANN) in modeling predictions of tractor operation. Prediction of tractor operation is a prediction of tractor use on a certain day using input data obtained before the day of tractor use. ANN modeling uses the back-propagation supervised learning method. The best ANN model used four hidden neurons with a learning coefficient of 0.2, a momentum of 0.8 and 20,000 iterations. This model has been able to provide optimal predictions with an accuracy value of 77%. The ANN model has been successful in predicting tractor operation on dry land using the back-propagation supervised learning method

Growth and Production of Hydroponics Chinese Flat Cabbage With Ab Mix Concentration and Android Based Monitoring
Get PDFHydroponic cultivation is an alternative choice for people who plant various types of plants that can be consumed by themselves every day. In addition, hydroponics is one way to grow crops on a large scale without requiring land that is very suitable for cultivation in urban areas. However, this system has several drawbacks, namely, hydroponics really requires a controlled environment, such as monitoring the degree of water acidity, water temperature, and water nutrient density. It needs to be monitored and controlled to avoid a decrease in plant quality. Several ways can be done by using manual measuring tools which actually take time if the hydroponic system is on a large scale, the alternative is to use an Android-based control and monitoring system. This study aims to examine the effect of the best AB Mix nutrient concentration on the growth and production of Sawi Pagoda with the NFT hydroponic system and to control pH, temperature, humidity and nutrients automatically using the Ardiuno Uno sensor. This research was conducted at Rootop PS. Plantation Cultivation from August to October 2020. The design used was a completely randomized design consisting of one factor, namely the concentration of AB mix nutrients consisting of 2 levels: A1: 1000 ppm: 1200 ppm: 1400 ppm (given according to the age of the plant per / week) and A2: 1100 ppm: 1300 ppm: 1500 ppm (given according to plant age per / week). The research was repeated as many as 20 replications so that there were 40 experimental units. The results showed that the A1 treatment level with the concentration of AB Mix nutrient solution (1000 ppm: 1200 ppm: 1400 ppm) was the best treatment level for the increase in plant height and number of leaves on the 2nd and 3rd week and the final plant weight. The hydroponic Nutrient Film Technique system can be monitored and controlled automatically by Arduino, making it easier to control temperature, humidity, ppm of nutrients, and nutrient pH.
