Abstract

Aquaponic cultivation systems require good care and management. Aquaponics that are not managed properly have great potential to cause failure in aquaponic cultivation itself. To simplify management, a system that can simplify the process is needed. The purpose of this research is to create a system that can help manage aquaponic cultivation. The system has a built-in aquaponic condition monitoring feature via an installed sensor. The conditions monitored by this system are conditions of air temperature, humidity, water temperature, light intensity, level of turbidity of water, and height of fish feed at the feedlot. The system has two automation features. The first automation feature is the automation of fish feeding with a certain time lag. The second automation feature is the automation of the water heater engine. Water heater engine will be turned on or off at a certain temperature. The system also features an engine control feature in aquaponics that includes a water pump engine, an aerator engine, and a water heater engine. System monitoring, automation and control features can be accessed by users via the web. Testing of the system has indicated that the system is functioning properly in accordance with the objectives. The algorithm is correct, so the system output matches the expected output.

Abstract

Digital literacy is an ability to acquire, understand and use information derived from various sources in digital. Along with the rapid development of information and communication technology in the revolution 4.0, the government requires teachers in schools through the national literacy movement, teachers are required to not only be able to use digital technology but also to assess the validity of information obtained from digital sources. The purpose of this research to know the information literacy skills of teachers in elementary school. This research used a qualitative research design descriptive. The sampling method is a stratified random sampling technique in 104 teachers from 5 elementary schools in Bogor. The results of this study indicate the level of digital literacy among elementary schools teachers in the city of Bogor is already middle in all aspects of competence, both on internet searching aspects, hypertextual navigation aspects, content evaluation aspects, and knowledge assembly aspect

Abstract

The availability of stock in the chicken egg supply chain is influenced by the ability of egg Agents to determine the optimal orders to suppliers. The optimal number of orders is very important to manage for the Bogor City Egg Agent Indonesia because the stock capacity reaches 340 crates. The optimal number of orders for eggs at the Egg Agent is influenced by input variables, namely final stock (crate), selling price (crate), and consumer demand (crate) so that the inventory is under control. The three input variables have fuzzy values that must be processed using fuzzy logic to get the optimal number of orders to suppliers so that the egg stock in the warehouse is well maintained. The optimal order model for eggs in the smart application for egg agent (SAFEA) was developed using a fuzzy logic approach with the triangular and trapezoidal membership function. Based on the optimal order model in the SAFEA application, the optimal order to the supplier is 100-104 crates per day.

Abstract

This study aims to evaluate the supply aspect of chicken eggs. The Variables used in this research were egg stock, egg demand, and selling prices with alternatives are adding suppliers, adding customers, reducing supplier. The method of this research using Fuzzy AHp where The membership sets of fuzzy model are Triangular and Trapezodial membership function. The results of the research indicate that the main priority as a decision support for the supply of chicken egss is the selling price to customer (0,67), so that the alternative priority option is the addition of suppliers (0,75) to anticipate imbalances between the number of eggs sold and stock availability in the warehouse.

Abstract

A greenhouse is an agricultural management system that has shown the efficiency of food production. This system is an effective alternative to ensure maximum production results. Agriculture with greenhouse technology can create the desired environmental/climatic conditions. The rapid development of technology and science has led to the birth of communication between devices using IoT and AI. This technology can be applied to greenhouses in agriculture and fisheries. Research on greenhouse and microcontroller-based automation systems has been carried out, and it is interesting to be developed. Researchers make a more efficient system and can increase the quality and quantity of production. The measurement data of both modes are monitored using the web. The greenhouse prototype is supported by DHT22, DS18B20, a fan to control the greenhouse cooler, RFID as the key access to the greenhouse. DHT22 & DS18B20 sensor readings in the prototype greenhouse use an AI system with the fuzzy method. IoT and AI have been successfully implemented in models of rice fields, hydroponic farming, and fisheries using automatic modes of RTC devices and sensors. The fuzzy approach method is used to find the optimum temperature and humidity values. The fuzzy approach was successfully carried out until the temperature and humidity conditions were "ideal," "high," and "very high." This condition provides information to the microcontroller to activate which fan should turn on. In manual mode, the smartphone application controls the system properly.

Abstract

Lake is an inland water ecosystem whose existence is very important for human life (Lihawa & Mahmud, 2017). For humans, the importance of lakes means much more than their area. The existence of a lake ecosystem provides beneficial functions for human life (Pratama et al., 2018). Apart from being a source of raw water, irrigation and hydroelectric power, inland public waters have high economic benefits, especially in the development of the fisheries sector, both capture and cultivation. The potential for capture fisheries in mainland public waters is estimated at 3 million tonnes (Triharyuni et al., 2014). The multisectoral utilization and activities in the area around the lake have caused the lake ecosystem to experience increasingly severe degradation until now.To detect and measure the effect of a pollutant on environmental quality and to determine the improvement in environmental quality after the pollutant has been removed (Bahri, 2018). Based on several studies that have been carried out in relation to water quality, parameters that are quite influential on the development of cultivated fish include temperature, salinity, brightness, turbidity, degree of acidity (pH) and dissolved oxygen (Mahabror 2013).
