Optimalisasi Labview Sebagai Kendali dan Monitoring Arus Tegangan pada Modul Solar Cell Menggunakan Jaringan Lokal

Renewable energy sources in Indonesia have been widely used, one of which is solar energy, for various needs, one of which is for solar power generation by using solar cells as the medium. In generating electricity, solar cells are very dependent on the intensity of the sun so as to produce currents and voltages that are not constant. Because of this, a monitoring system was created to monitor the current and voltage in a solar cell module to determine current and voltage conditions. In this study, the monitoring system used wireless data transmission via the XBee S2C module installed on the Arduino Mega 2560 and Arduino UNO. The INA 219 sensor is mounted on a solar cell module along with a relay module connected to the Arduino Mega 2560 and the XBee S2C module. The test results show that wireless data transmission cannot be used indoors at a distance of more than 20 meters. The INA 219 sensor as a reader for DC current and voltage parameters has an error rate of 0.49% to 0.75% for voltage and for DC current readings it has an error rate of 1.85%. The results of current and voltage readings are displayed on a LabVIEW interface in real-time and can be accessed via a web browser using a local network. Relay control carried out through LabVIEW has a delay time of 6.08 seconds. Logging data can be stored in .xls files and data displayed on a web browser has a delay of one to two seconds

Pemanfaatan Rawa Pasang Surut Untuk Tambak Ikan Bandeng

Tritih Lor is a village at Cilacap that consists of swaps that are formed by ocean tides. Our partner as a fish farmer group at Tritih Lor has utilized the swamp for milkfish cultivation to use a traditional system. There are some troubles on their business like the production is too low because they use a traditional system that relies on natural food from a relic carried away by the tides. Another problem that the fish are gone along the tide when the fish pond breaks. To solve that problem, we use a method of repairing the fish pond, install and arrangement of water intake and aeration systems, installation fence around the fish pond, installation of solar panels, pond fertilization, stocking the pond, and harvesting. The result of this activity is an increase in productivity and a decrease in fish mortality. This semi-intensive tidal swamp aquaculture pond can answer the previous problems of traditional cultivation. This activity also can create more technological-based cultivators, make a better income, and increase the usability of the unused land
