Abstract

Synthesis of g-Al2O3 from Tatakan, South Kalimantan kaolin using simple methods: metakaolinization, dealumination, precipitation process using polyethylene glycol (PEG-6000) as a structure directing agent, calcination steps, and characterization of its products have been presented. The purified kaolin was metakaolinized and dealuminated to get amorphous aluminum hydroxide.  After that, the sample was precipitated using the various concentration of PEG and NH4OH as the precipitating agent. Calcination process was carried out at calcined at a temperature of 700°C for 3 hours. Based on the FTIR spectra and X-ray diffraction of the g-Al2O3 obtained was similar to that of commercial g-Al2O3. The highest crystallinity of g-Al2O3 was formed when using twice of critical micelle concentration of PEG (10-3 mol/L).  This simple process is an industrially practicable substitute to the Bayer process

Abstract

In this research, the synthesis of nanocellulose from Nypa fruticans fronds as a filler of polyvinyl alcohol-based bioplastic has been carried out. Nanocellulose synthesis was carried out using sulfuric acid hydrolysis process with a concentration of 30% and the results were analyzed using a Particle Size Analyzer. The effect of addition of the amount of nanocellulose on bioplastics from polyvinyl alcohol such as moisture content, thickness, transparency, vapor transmission rate, solubility and functional group analysis using FTIR have been evaluated. The results showed that the nanocellulose from Nypa fruticans fronds had a diameter below 600 nm. The addition of nanocellulose with a concentration of 0.2%; 0.4% and 0.6% into the polyvinyl alcohol bioplastic can increase the thickness and transparency of the bioplastic, and reduce the water vapor transmission rate. However, the addition of nanocellulose in this range did not significantly affect the water content and the solubility of bioplastics in water.

Abstract: The bioplastic synthesis of alginate in this study has been carried out using nanocellulose from sago fronds as a filler. Bioplastic synthesis uses different nanocellulose concentrations, namely 0%; 0.2%; 0.4%; and 0.6% (w / w). This study aims to see how the characteristics of bioplastics with the addition of nanocellulose. The resulting bioplastics were analyzed for moisture content, solubility, thickness, transmission rate, and transparency. The results of the research on the addition of nanocellulose concentrations show that nanocellulose can improve the characteristics of bioplastics in the form of thickness, transparency, moisture content, solubility, and water vapor transmission.

Abstract

Guntung Payung land condition majority is peat that makes low productivity of vegetables, difficult land preparation, and much consume of fertilizer. In the other hand, partner location in this program is an urban area that near international airport, caused the change in land function from the farming area to be residence area. That condition caused the traditional farming area is not enough. The low education level and skills of community inhibit to learn and try new technology for increasing income level. The training of the hydroponic system to the community in this program can solve the problem that happens in this partner community. With knowledge of hydroponic technology, it is expected that the partner’s income will increase and this group of hydroponic farmers can supply the vegetables need in Banjarbaru area.

Abstract

Sago plants can be used from leaves, fronds, and stems with the main product of sago starch from the stem. In the production process, the sago plants used are 7-8 years old. The productivity of sago palms in Pemakuan Laut village is around 200 kg starch/stem with a selling price of Rp. 3,500/kg in wet conditions and Rp. 7,500/kg of dry sago flour. Sago processing waste has not been utilized yet by the community even though the waste can still be used for other purposes such as animal feed, hardboard, fuel, plant growth media, and fertilizer. Sago waste is a problem in the Pemaku Laut village environment because the waste has accumulated while the location for disposing of it is limited. Therefore, in this community service activity training was carried out in making animal feed (poultry) using sago dregs. The method used is fermentation. From the activities carried out, it was known that all the participants had started to utilize sago dregs, but the preliminary process had not been carried out, the dregs were directly given to livestock. In this training, sago dregs processing is carried out using the fermentation process. From the training, it can be seen that the community already knows the process of processing the dregs before giving it livestock to increase its nutritional value.

Abstract

Synthesis of surfactant modified kaolin from natural kaolin from Tatakan, Tapin, South Kalimantan and its application for carrier material of gibberellic acid have been conducted. The kaolin modification was done by surface engineering using cationic surfactant cetyltrimethylammonium bromide (C16TMABr). The characterizations of kaolin and surfactant modified kaolin were carried out by XRF, SEM, XRD, FTIR and TGA/DTA. The adsorption capacity of kaolin was determined by Langmuir adsorption isotherm model. The result showed that kaolin from Tatakan, South Kalimantan consist of kaolinite, halloysite, quartz, chlorite, and christobalite. Surface modification using cationic surfactant showed that increasing surfactant content onto kaolin was proportional to the amount of surfactant loaded. Gibberellic acid was partitioned into the organic phase created by the surfactant tails of the C16TMA+ modified kaolin. The calculations result by Langmuir adsorption isotherm model showed that the highest increasing adsorption capacity occurred on surfactant modified kaolin with surfactant/CEC ratio of 2.0, with the adsorption capacity of 28.41 mg/g.

Abstract

Preparation, activation and adsorption study of natural kaolin from Tatakan, Tapin, South Kalimantan have been conducted. The activation of kaolin was done using 6 M HCl solutions at 90 °C for 3 h. The characterizations of kaolin were carried out by Fourier Transform Infrared, X-ray diffraction, and surface area analyzer. Adsorption parameters studied included the effect of pH, contact time, and concentration of gibberellic acid (GA3) onto kaolin samples. The amount of gibberellic acid adsorbed was determined using UV spectrophotometer. The adsorption capacity of kaolin was determined by Langmuir adsorption isotherm model. The result showed that activation of kaolin was resulted the larger specific surface area and more homogeneous composition of kaolin without any destruction of kaolin structure. Adsorption of gibberellic acid onto kaolin before and after activation showed that optimal adsorption was obtained at pH » 7 and reached the equilibrium within 4 h. The calculations result by Langmuir adsorption isotherm model showed that the increasing of adsorption capacity of acid activated kaolin is about 35%.
