Abstract

The objective of this study was to evaluate the variations of twelve chemical elements (Ni, Fe, Co, Mg, Mn, Al, Si, Zn, Ti, P, Ca and Cr) in laterite soil profiles from Wantulasi area in South East Sulawesi Province of Indonesia. Eighty four (84) samples of three profiles (i.e. each profile consists of eight samples) had been used to study their variations in soil using the X-Ray Fluorescence (XRF). Results analysis of the chemical elements content in three profile using XRF indicated that there were good correlationsbetween the chemical elements in the soil profile with the significant correlations were found in Ni and Fe, Ni and Si, Ti and P, Fe and Al, and Co and Mn, respectively. On the other hand,the results of study showed that the variations of the chemical elements could be related to the enrichment and translocation of the elements in soil profile and also their possibilities to be related with a given chemical elements in soil profile. Therefore, we suggest that the observed patterns in chemical elements with a good correlation in laterite profile can be used as proxies to integrate the evaluation of the chemical and physical weathering process based on the elements characteristics in soil profiles.

Abstract

This study used a composite of activated charcoal and iron sand extract to reduce the concentrations of heavy metals (Cu, Ni, Zn, Pb, and Cd) in polluted seawater. The grain size of the composite was varied to 60 mesh, 100 mesh, and 200 mesh, with a ratio of activated charcoal to iron sand of 2:3 to optimize absorption. The composite was then compacted into pellets with compaction pressures of 42.2 Pa, 84.8 Pa, and 141.5 Pa, respectively, to achieve optimum compressive strength. The concentrations of heavy metals were measured using an Atomic Absorption Spectrophotometer (AAS). The optimal compaction pressure for the composite was found to be 141.5 Pa, with absorption efficiencies of 61% for Zn, 96% for Pb, 48% for Cd, 90% for Cu, and 94% for Ni. According to the research results, the highest absorption was obtained in composites with a grain size of 200 mesh, with absorption efficiencies of 62.21% for Zn, 96.87% for Pb, 48.14% for Cd, 90.98% for Cu, and 94.15% for Ni. The greater the compaction pressure exerted on the composite, the higher the absorption percentage of the composite pellets. Conversely, a finer grain size also contributes to higher absorption.

Abstract

Pond water pollution is the main problem in vannamei shrimp cultivation, so to overcome this problem, The decline in water quality is caused by a decline in the quality of pH, salinity and temperature in pond water. Researchers created the Quamonitor tool to monitor IoT-based vaname shrimp pond water. The research was conducted using the Research and Development (R&D) method with the Analyze, Design, Develop, Implement and Evaluate (ADDIE) model, assisted by WiFi, MQTT and Node Red networks to monitor water in order to display monitoring results on Android. This study aims to monitor the condition of vaname shrimp pond water quality in the form of pH, temperature, and salinity parameters using pH E-4052C sensor, DS18B20 temperature sensor, TDS/Conductivity DFRobot V1.0 sensor and NodeMCU ESP32 as a data manager and system controller that runs in real time. The test results of PH sensors, temperature sensors and TDS/conductivity sensors obtained a sensor error percentage of 0.29% for pH parameters, 1.7% for temperature parameters and 0.41% for salinity parameters. Based on the sensor error value, Thingspeak graph display, real time monitor display on Android, it can be said that the manufacture of the Quamonitor tool for IoT-based vaname shrimp pond water quality monitoring is successful and can function well
