Abstract

Activated carbon (AC) from agricultural waste has become one promising way to produce AC regarding to low price of the precursor and its effect to environment. In this research, the solid waste from the basic biology practical in UPT. Basic and Central Laboratory, Andalas University (Unand) was utilized as the precursor for producing low price AC. The activation was done by chemical activation using three different activating agents which were zink chloride (ZnCl2), phosphoric acid (H3PO4), potassium hydroxide (KOH). The carbonization process was done at temperature of 700°C. The precursor and three different AC after activation were characterized using fourier-transform infrared spectroscopy (FT-IR) to examine the functional group and scanning electron microscope (SEM) to observe the pores structure. The adsorption efficiency (AE) of each AC on methylene blue (MB) contained in laboratory wastewater was examined through adsorption process with retention time of 30 minutes at room temperature and neutral pH. SEM analysis showed that the three activating agents were resulting in higher surface area and more pores were formed. The highest AE of MB from laboratory wastewater for each AC were 97,5 %, 96,31%, and 90,79 for KOH, , ZnCl2, and H3PO4, respectively. Meanwhile, the highest adsorption capacity was achieved by AC through KOH activation with 0,003 mg/g

Abstract

Recent studies on agricultural waste as a potential precursor of biochar for heavy metals removal from aqueous solution had not considered exhausted coffee husk (ECH) as the potential one. It is well-known that the carbonization process influences the removal performance of biochar, particularly removal efficiency (RE). However, previous studies rarely considered the energy consumption during the carbonization process. The major objective of this study is to investigate the optimum carbonization parameter on ECH biochar for removal of ion Pb and Cu from economic stand point. The ECH biochar was produced at the different heating temperature (300 – 600°C) and heating time (30 – 120 minutes). In regard to specific cost of bio-sorption, the results showed that 500°C was the optimum heating temperature of ECH biochar for the Pb removal, while 600°C was the optimum one for the Cu removal. Furthermore, the heating time experimental outcomes suggested that the optimum heating time were 30 minutes for Pb removal and 120 minutes done Cu removal.  Key words: Biochar, carbonization temperature, carbonization time, exhausted coffee husk, specific energy cost

Abstract

Indonesia is recently facing the fertilizer issue as the shortage supply of subsidized fertilizers is aligned with the increasing price of non-subsidized ones. So, it eventually resulted in the unstable price of agricultural commodities. The issue has been becoming an obstacle for farmers practising agricultural cultivation, particularly those in Batang Tajongkek Village, Pariaman, West Sumatra Province. It needs to develop its potential for natural resources to make organic fertilizer from cow manure. Furthermore, the solution supports the government program on establishing integrated agriculture. Two activities were conducted to empower the area's potentials, which were counselling and composting demos, respectively. The aim was to ensure knowledge transfer to the farmers regarding the technology and critical method of cow manure composting. During the counselling, the farmers were facilitated to discuss the related issue of sustainable integrated agriculture, organic farming, and the making process of compost. Meanwhile, the process of composting from cow manure was also shown during the demo. Furthermore, the farmer was facilitated to analyze the content of produced compost, which was mainly focused on the content of nitrogen (N), phosphorous (P), and potassium (K). The activities have empowered the people in the area to self-produce cow manure compost as an organic fertilizer. The analysis of the produced compost showed that the compost has yet to fulfil the national standard of solid fertilizer (SNI 7763:2018) regarding the content of macronutrients (N + P2O5 + K2O). However, the pH of produced compost has met the national standard. The pH was 7.27, which ranges from 4-9. For the compost to be utilized by the community, it is necessary to mix other materials in its manufacture so that the resulting compost complies with SNI.

Abstract

Machine learning and internet of thing (IoT) would be the best option for monitoring the appropriate soil pH condition. This research aimed on the design an automatic soil pH control system based on IoT for monitoring the cultivation of Aloe vera plants. The Telegram application was occupied as an IoT platform and was connected to a free and easy access application, Node MCU 8266. Furthermore, relay, Arduino Uno and smartphone were occupied in the system. According to the system testing, soil pH sensor readings are close to the actual value as evidenced by the linear regression value or R2 on sensors 1 and 2 which are close to 1. Meanwhile, the total percentage of system performance testing was 93% while the error value for the pH sensors were 0.96 and 1.6% for sensor 1 and sensor 2, respectively. Furthermore, the plant observations showed that the average leaf length of plants with a control system was 24.78 cm while with the manual system was 23.11 cm. From the results of the T test obtained, it was found that the control system applied to Aloe vera cultivation had a significant effect on the growth and development of Aloe vera compared to Aloe vera plants with a manual system.  Keywords: Aloe vera, Control system, Internet of things (IoT), Soil pH sensor

Abstract

In recent years, various industrial activities have introduced a high concentration of iron in the waterbody which causes serious problem to environment. This paper proposed the application of Exhausted Coffee Husk (ECH) as the biosorbent (BS) for removing iron (Fe) (II) in the aqueous solution. The ECH was carbonized into biochar before performing biosorption of the heavy metal ion. The effect of carbonization temperature, time and rate on the performance of the ECH biochar for removing Fe (II) were evaluated. The percentage of removal efficiency (RE) and the capacity of biosorption (mg/g) were considered as the determining parameters. The pyrolysis temperature was varied in a range of 200-600 °C with 50 °C of interval, while the time was in between 1h – 3h with a n interval of 0.5 h, and the temperature gradient of 5 – 25°C/min. The results showed that the temperature had a significant effect on the properties of the ECH biochar as BS for Fe (II). The temperature of 550 °C, at 1.5 h of time and 25 °C/min was chosen as the suggested carbonization temperature of biochar from ECH for biosorption of Fe (II).  Keywords:  Agro-industrial solid waste, Biosorption,  Carbonization, Exhausted coffee husk (ECH), Heavy metal.

Abstract

In this study, biochar derived from exhausted coffee husk (ECH) was used as biosorbent for removing Iron (II) from aqueous solution. The aim of this study was to improve the biosorption capacity of the biosorbent from agricultural solid waste and its usability for Fe²⁺ removal. The biosorption performance of ECH biochar was optimized through carbonization parameters: temperature, time, and temperature gradient. Response Surface Methodology (RSM) based on multivariate analysis was employed to evaluate the biosorption performance of ECH biochar for Fe²⁺ biosorption. The optimum performance predicted through Box-Behnken design experiment. The optimal combination of the three parameters was 549.37°C, 1.98 h and 21.98°C/min. At the optimal condition the removal efficiency (RE) was predicted to be 107.01% and biosorption capacity (qt) was 5.11 mg/g. SEM-EDX, FT-IR and XRD analysis were conducted in this study to evaluate the biosorption mechanism of ECH biochar on the iron ion. The results showed that ion exchange existed on the surface of the ECH biochar during the biosorption. Additionally, the presence of functional groups on the ECH biochar surface responsible for Fe(II) binding. Overall, the findings of this study suggested an eco-friendly strategy for optimizing the removal of Iron (II) from polluted water by the biosorption onto ECH biochar. Keywords: Biochar, Biosorption capacity, Box-Behnken design, Temperature, Time

Abstract

The primary goal of this study was to investigate the biosorption performance of biochar derived from exhausted kahwa coffee (EKC) on removing heavy metal ion, Cd²⁺ in the solution. The operational parameters, for instance pH, dosage and contact time, were varied in a certain range and the efficiency and the capacity of removal were determined. The pH was in a range of 5 – 11, while the biochar dosage in a range of 0.075 – 0.15 g and the contact time was in between 30 – 180 minutes. The batch biosorption test showed that the EKC biochar had higher removal performance in alkaline condition, with a proposed pH of 10. Meanwhile, the applied dosage showed that addition of 0.1 g EKC biochar was more effective than adding more dosage. Furthermore, the batch experiments showed that 60 minutes of biosorption process resulted in more effective removal compared to the longer biosorption time. According to the ANOVA analysis on the three conditions, it was shown that the pH and contact time had significant effects on the removal performance of EKC biochar on cadmium ion in the solution.  Keywords: Biochar, biosorption, Exhausted kahwa coffee, Heavy metal ion, Operational parameters.
