Abstract

Rice husk is an organic material that has a high lignocellulosic content so it has the potential to be turned into activated carbon. One method of making activated carbon is activation with a phosphoric acid activator (H3PO4). The purpose of this research was to study the effect of varying concentrations of H3PO4 as an activator on the characteristics of rice husk-activated carbon. The characterization refers to SNI 06-3730-1995 regarding the technical quality requirements of activated charcoal. Activation of rice husk carbon was carried out by contacting the carbon with H3PO4 for 24 hours and shaking it. The H3PO4 consisted of 3 concentration variations, namely 4M, 6M, and 8M. From the research results, the water content was 3.936%; 4.037%; 4.070%, the absorption of iodine has met the character of activated charcoal according to SNI, namely 1217.204 mg/g; 1204.255 mg/g; 1184.832 mg/g while the ash content value does not meet the SNI standard, which is still above 10%. The highest adsorption capacity and adsorption efficiency could be activated with 8M H3PO4, namely 22.42 mg/g and 89.68%. IR spectra on activated carbon with three variations of H3PO4 concentration showed the presence of aromatic C-H, C=C, and C-O anhydride functional groups.

Abstract

Aquaponics is an application of a sustainable agricultural system by integrating the cultivation of plants and fish at one time. Water availability in plant commodities and water is optimized in aquaponic cultivation systems. Several parameters that can determine the level of success of cultivating an aquaponic system include water pH, water temperature, TDS, and water level. The process of monitoring and controlling several important parameters in cultivation can be done conventionally, but it is less effective and efficient because the cultivator has to check and measure the parameters every time. Therefore, as time goes by, and technology becomes more sophisticated, a control and monitoring system is designed. several parameters such as water pH, water temperature, TDS, and water level based on the Internet of Things (IoT) to support the success of the aquaponics system by monitoring environmental conditions using a laptop/smartphone at that time. Based on the test results, it was found that aquaponics in an indoor environment is successful - the air conditioner has a water temperature below 250C, the water pH shows 7pH and the average nutrient in the water shows 214.5 ppm. Based on this, kale plants in the stem grow quickly while leaf growth is very stunted. At temperatures smaller than 25 0C pomfret fish only survive for 2 weeks but tilapia fish can survive and not die in these environmental conditions. The length of the tilapia fish for 6 weeks has increased by 5 cm from its original length
