Abstract

This research aims to synthesize and characterize MCM-48 modified with the group-NH2. Synthesis of MCM-48 and its modification by NH2 conducted by Ryoo methods where is the salt of Ludox HS40 solution mixed with NaOH solution then heated, followed by making mixture of CTAB and Triton X-100. The resulting gel mixture is heated at temperature of 100 °C for 24 hours. The reaction mixture added 30% acetic acid until pH 10. Then the mixture was heated at 100 °C for 24 hours then cooled at room temperature. MCM-48 mesoporous silica that has formed was filtered, washed with distilled water and dried at 120 °C. MCM-48 mesoporous silica characterized using XRD and FTIR. Modification of MCM-48-NH2 was done by adding 3-APTES into mesoporous silica. XRD analysis results showed that the characteristic peaks at 2 theta 2.4o have Miller indices 211and several peaks with low intensity. These peaks are typical peak for MCM-48. By FTIR showed the specific areas observed for organic molecules (surfactant) in MCM-48 synthesized; CH span (2800-3100 cm-1) and CH bending (1400 to 1500 cm-1). C-H bending vibration was observed in 1645; 1512 and 1481 cm-1. The success of modified MCM-48-NH2 was shown by the appearance of two absorption bands at wave numbers 3368 and 3424 cm-1 which indicate the presence of a primary amine or an amino group (-NH2) in the mesoporous channel

Abstract

Biosynthesis of silver nanoparticles (AgNPs) using ketapang leaf extract, modification with p-coumaric acid for detecting melamine has conducted. This research aimed to synthesize AgNPs via bio-reduction method using ketapang leaf extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis) and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Further analysis of crystallite via XRD suggested that nanoparticle size at 43 nm estimated using Debye-Scherer, within the form of unit cells is cubic. The performance of product as melamine detector suggested that the AgNPs-APK had detected melamine in range of concentration from 0.1 to 1000 ppm.

Abstract

The research aims to synthesis of silver nanoparticles (AgNPs) via bio-reduction method using mangosteen skin extract. The growth of AgNPs was characterized by ultraviolet-visible spectroscopy (UV-Vis). Based on Surface Plasmon resonance (SPR) data, observation suggested that an increase of initial AgNO3 concentration along with temperature, had affected its surface Plasmon resonance trend. SPR absorption indicates that the concentration of AgNO3 and the synthesis temperature was instrumental in the formation of silver nanoparticles.

Abstract

Biosynthesis of silver nanoparticles (AgNPs) using mangosteen bark extract, modification and its application in detecting melamine has conducted. This research aimed to synthesize AgNPs via bio-reduction method using mangosteen bark extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis), Fourier transform infrared absorption spectroscopy (FTIR), and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Observation of functional group by FTIR showed that carbonyl group (1707 cm-1) suspected from hydroxyl group (3414 cm-1). Further analysis of crystallite via XRD suggested that nanoparticle size at 30 nm estimated using Debye-Scherer, within the form of unit cells is cubic. Modified AgNPs showed an interaction between APK and particle surface through C=C alkenes (1598 cm-1) and aromatics (1672 cm-1), =C-H aromatic (3070 cm-1), aliphatic C-H (2501 cm-1), C-O (1107 cm-1) and C=O carboxylate (1774 cm-1). The performance of product as melamine detector suggested that the AgNPs-APK had detected melamine in range of concentration from 0.1 to 1000 ppm.

Abstract

Mattirodeceng is a village located in Pinrang Regency, which has considerable natural resource potential in coconut production. But the utilization of coconut plants, especially the water of coconut, is still low. Coconut water only used for consumption purposes at certain times. The purpose of this activity is to provide training on the benefits and ways of processing coconut water into soy sauce for PKK groups in the Mattirodeceng village. The method used in this activity consisted of the pre-activity stage, which included a survey of the location and trial making of soy sauce made from coconut water. The implementation of activities carried out by counseling methods and training on the benefits and ways of processing coconut water into soy sauce. The result of the application of this activity was an increase in participants' knowledge about coconut water, namely its nutritional content, and its processed products in the form of soy sauce. The Organoleptic test showed the level of panelists' preference for taste, flavour, texture, and color showed good results, where all panelists liked the coconut water soy sauce products   Keywords: Coconut water, soy sauce, organoleptic Mattirodeceng Village.   ABSTRAK Mattirodeceng merupakan salah satu desa yang terletak di Kabupaten Pinrang yang memiliki potensi sumber daya alam yang cukup besar dalam produksi kelapa.

Abstract

Coconut, particularly coconut water, serves many purposes in people's lives. Coconut water is generally consumed with the young fruit, but old coconut water is frequently discarded into the environment. Therefore, integrating coconut water into a product has a high economic value. The aims of this community service is to process coconut water into nata de coco by empowering the community through training for PKK members. This program's methodology included partner problem analysis and the available problem-solving strategy, which consists of counselling, training, and collecting data. The implementation of this activity resulted in numerous benefits, particularly increased public understanding of the role of coconut water in daily life, such as its nutritional value, processed products such as nata de coco, and other advantages. Based on the data collected, it is known that all participants have differing levels of knowledge about nata de coco products, namely 10% of participants know very well, 30% of participants know, and 12% of participants know little. However, 58% of participants were totally ignorant that coconut water is the starting material in nata de coco. Following the training, all participants understood that coconut water was the raw material in nata de coco. On the other hands, 75% of the participants were very understanding, 20% were quite understanding, and only 5% had a basic understanding of how to make nata de coco. These findings indicate that the solution of the activities carried out is extremely effective in increasing the participants' understanding and interest in making nata de coco, which can encourage the creation of "home industry" based jobs in the community, particularly in Tiroang Village.Â
