Abstract

One of the fish in Indonesian waters that has been successfully bred and cultivated is the catfish (Pangasius sp.). In catfish farming, there are several water quality factors that need to be considered, such as temperature and dissolved oxygen levels. Based on the existing description, it is very important to pay attention to the water quality of aquaculture ponds, especially temperature and dissolved oxygen levels for fish survival. This study aims to create an internet of things (IoT) based monitoring system for temperature and dissolved oxygen levels in catfish aquaculture pond water based on NodeMCU ESP8266. Monitoring system is using SEN0237 gravity analog dissolved oxygen sensor, DS18B20 sensor module, NodeMCU ESP8266, 20×4-character liquid-crystal display (LCD), micro secure digital (SD) card module, internet modem. Data from measurements of temperature and dissolved oxygen levels are stored online in the Adafruit.io database in the .csv format and on a micro secure digital (SD) card in the device in the .txt format. The lowest value of dissolved oxygen levels and temperature are 3.4 mg/L or 3.4 ppm and a temperature of 27.9 °C, respectively. Meanwhile, the highest value of dissolved oxygen levels and temperature are 4.6 mg/L or 4.6 ppm and temperature of 30.9 °C, respectively.

Abstract

Lead as the most commonly used material for radiation shielding but possessing toxic properties. This research aims to identify alternative, lead-free, and non-toxic materials for gamma radiation shielding through Monte Carlo simulations. Bismuth Oxide (Bi2O3), Barium Oxide (BaO), Tungsten Trioxide (WO3), Tungsten Dioxide (WO2), and Molybdenum Trioxide (MoO3) were selected as potential substitutes for lead. Pure lead (Pb) and Lead Oxide (PbO) were used for comparison. The simulation were performed using Particle Heavy Ion Tracking System (PHITS) software, with a gamma energy of 662 keV. The result of the simulation shows that the linear attenuation coefficient values for Pb and PbO were 0.902 mm-1 and 0.74 mm-1, respectively. Meanwhile, the simulation results of those simulated materials that are closest to Pb and PbO are Bi2O3 and WO2 with an attenuation coefficient of 0.71 mm-1. This simulation shows that for non-lead materials, BiO2 and WO2 have potential as alternative of non-lead radiation shielding.

Abstract

Community service activities at Nana Fishery located in Guntung Paikat Village, Banjarbaru have been completed. The application of solar cell technology has been applied in the fisheries sector. Solar cell alternative energy technology has been applied in running water pumps to supply oxygen content in water. Water quality, especially in the fisheries sector, must always be maintained so that fish growth and development grow optimally. Partners have gained knowledge about solar cell technology which in this case has been directly applied in the fisheries sector. In this activity, two solar cell panels with a power of 100 watt- peak (WP) have been installed, the water pump used is 30-Watt DC, 5 DC lights with a power of 10 watts. The specifications of the two batteries have a power of 12 Volts, 50 Ah with a backup period of two days. In addition, an Arduino Uno-based timer is also installed which is programmed to be on for two hours and off for 30 minutes. Based on testing before being given a load, it has a voltage value of 13.8 Volts and after being given a load, the water pump and lights show a voltage value of 13.6 Volts.
