Abstract

Liquid organic fertilizer (LOF) is a solution resulting from the decomposition of organic matter originating from plant residues, agro-industrial waste, animal waste, and human waste containing more than one nutrient. LOF can be made from liquid organic matter (liquid organic waste), by composting and providing composting activators so that a LOF that is stable and contains complete nutrients can be produced. The use of LOF has the advantage that although it is often used it does not damage the soil and plants, the use of organic waste as fertilizer can help improve soil structure and quality, because it contains nutrients and other organic matter. The process of adding different fertilizers to the plants for 10 days showed that there were different height changes for each plant. With only water, the plants only reach 0.1 cm difference in 7 days. The plants that were given LOF and NPK (Chemical Fertilizer) gained height in only 4 days with heights 15.6 cm and 16 cm respectively. The growth percentage between LOF and NPK showed a significant difference in 4 days with 0.6% and 3.2 % respectively.

Abstract

This study aims to determine the adsorption equilibrium of the activated carbon of empty palm oil fruit bunches and KA-Cu(TAC) on Zn(II). Oil palm empty fruit bunches are used as a bio-sorbent in making carbon at a temperature of 5000 C, the resulting carbon is activated using H3PO4 and modified into a composite with metal organic frameworks of Cu metal and terephthalic acid. MOFs and KA-Cu(TAC) composites were produced by reflux method. Activated carbon, MOFS and KA-Cu(TAC) were characterized using XRD. The adsorption process of Zn(II) metal was analyzed using AAS and determined the optimum conditions with various concentrations to determine the adsorption equilibrium. XRD characterization results show that activated carbon has an amorphous structure, while MOFs Cu(TAC) and KA-Cu(TAC) have a crystalline structure. The optimum condition of activated carbon and KA-Cu(TAC) at a concentration of 180 ppm with the appropriate adsorption isotherm model is the Langmuir isotherm.

Abstract

This research aims to determine the adsorption ability of activated carbon and Fe-Cu modified activated carbon in the β-carotene adsorption process on Crude Palm Oil (CPO). Empty Palm Oil Bunches (TKKS) are used as a bio-sorbent for carbon production at a temperature of 500 ºC. The synthesized carbon was activated using H3PO4 and modified with Fe-Cu metal. CPO quality parameters such as Free Fatty Acids and Peroxide Number were analyzed to see the effect of adsorption on CPO quality. The β-carotene level in the CPO sample used is 472.1 ppm. The optimum conditions for using activated carbon in the β-carotene adsorption process are a mass variation of 8 grams with the β-carotene remaining after adsorption being 432.4 ppm, whereas by using Magnetic Activated Carbon, CPO β-carotene after adsorption remains at 426.1 ppm. Meanwhile, increasing the adsorption time causes the absorption of β-carotene to become greater. By using Activated Carbon the remaining β-carotene is 300.1 ppm after 120 minutes, whereas by using Magnetic Activated Carbon the optimum absorption time is faster and the amount of β-carotene absorbed is greater. The remaining βcarotene after absorption with Magnetic Activated Carbon was 288.7 after 90 minutes of adsorption. Apart from being able to absorb β-carotene, magnetic activated carbon is also better at reducing FFA and PV levels from CPO.

Abstract

Research on the slow release kinetics of Fe(III) ions from Activated Carbon/Alginate-Fe(III) composites or abbreviated as K/A-Fe(III) has been carried out. The aim of this research was to synthesize K/A-Fe(III) composite as a material that has the potential to become a slow release micronutrient fertilizer and to study the kinetics of slow release of Fe(III) ions from the composite. The K/A-Fe(III) composite was synthesized by mixing alginate suspension and activated carbon (alginate: activated carbon weight ratio = 1:3 and 3:1) until homogeneous. Composite grains were characterized using Fourier Transformed Infrared (FTIR) spectroscopy, the kinetics of Fe(III) release from the three composite variations found that KAlg31 composite showed more absorption and release of Fe ions than KAlg13.

Abstract

This study aims to determine the adsorption and desorption abilities of activated carbon and Cu-(TAC) composites in the β-carotene adsorption process on Crude Palm Oil (CPO). Oil Palm Empty Fruit Bunches (EFB) are used as activated carbon and modified with MOFs Cu-(TAC). Activated carbon and Cu-(TAC) composites were characterized by XRD, SEM-EDX, and BET. The concentration of β-carotene absorbed during the adsorption process was analyzed using a UV-Vis spectrophotometer. The variations used to determine the optimum conditions for absorption of β-carotene were the mass variation of the adsorbent and the variation in the contact time between the adsorbent and adsorbate. The results of the characterization of activated carbon showed a sharp absorption in the presence of O-H, C-H and C-O groups indicating the presence of cellulose. Activated carbon is amorphous and the Cu-(TAC) composite has a crystal structure and its pore size is mesoporous. The optimum conditions for the use of activated carbon for β-carotene adsorption were the mass variation of 8 grams with 0.495 ppm of β-carotene and contact time at 120 minutes with 2.605 ppm of β-carotene. The optimum condition of the Cu-(TAC) composite in the β-carotene adsorption process was at 4 gram mass variation with 1.026 ppm β-carotene content and optimum contact time at 60 minutes with 6.384 ppm β-carotene content. The ability of desorption can be seen from the percentage of desorption showing activated carbon in the 150th minute with 96.252% while in the Cu-(TAC) composite in the 30th minute with 88.188%.

Abstract

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.

This study aims to determine the stages in the process of making activated carbon, synthesis of porous polymer composites Cu(TAC) and activated carbon composites (KA-Cu(TAC) for adsorption of dissolved ammonia (NH4OH). To know the characterization results of activated carbon and KA- Cu(TAC), as well as knowing the optimum mass, concentration, and contact time of activated carbon KA-Cu(TAC) for the adsorption of dissolved ammonia. The research stages started from Empty Oil Palm Bunches (EFB) used as biosorbents for carbon production at 500oC. The resulting product was activated with H3PO4, then modified with porous polymer Cu(TAC) to make a composite. The KA-Cu(TAC) composite was synthesized by reflux method. Then MOFs, activated carbon and KACu(TAC) composite were characterized by BET. The BET characterization results showed that the successfully synthesized KA-Cu(TAC) composite experienced an increase in surface area.In the NH4OH adsorption process the optimum mass efficiency on activated carbon still increased at 8 grams while the KA-Cu(TAC) composite obtained an efficiency of 36, 6% and optimally at a mass of 4 g. At variations in concentration, the efficiency of the two samples still decreased. And the optimum time efficiency obtained in the NH4OH adsorption process with activated carbon was 70% and the KA-Cu(TAC) composite was 86.6%, both samples were equally optimal at 75 minutes.
