Abstract

A molecularly imprinted polymers (MIP) can be synthesized using functional monomers and template molecules through polymerization with the aid of cross linker. In previous studies, MIP_TFMAA-co-EGDMA was synthesized using the main ingredient tryfluoromethylacrylic acid (TFMAA) as functional monomer, b-sitosterol as a template molecule and ethyleneglycol dimethacrylate (EGDMA) as cross linker. The ability of adsorption against the effects of pH and contact Time of MIP has been evaluated. Variations of pH standard solution b-sitosterol were 4, 5, 6, and 7, while the time variation used were 30, 60, 90, and 120 minutes. The data of b- sitosterol concentrations adsorbed by MIP_TFMAA-co-EGDMA because of the influence of pH and contact times were analyzed using high pressure liquid  chromatography (HPLC). pH5 gives the most influence on the adsorption capacity MIP_TFMAA-co-EGDMA against b-sitosterol. The number of b-sitosterol adsorbed on the pH was 1.0265 mg/g, while at 90 minutes was the best time for the MIP b- sitosterol adsorb as much as 1.3486 mg/g. Based on the adsorption kinetics study, the adsorption ability MIP_TFMAA-co-EGDMA against b-sitosterol in accordance with the pseudo second order kinetic model.

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. Namun pemanfaatan tanaman kelapa, terutama air kelapa masih rendah. Air kelapa hanya digunakan untuk keperluan konsumsi pada saat-saat tertentu. Tujuan dari kegiatan ini yaitu untuk memberikan pelatihan manfaat dan cara pengolahan air kelapa menjadi kecap kepada kelompok PKK di desa mattirodeceng. Metode yang digunakan dalam kegiatan ini terdiri dari tahap pra kegiatan yang meliputi survei lokasi dan uji coba pembuatan kecap air kelapa. Tahap pelaksanaan kegiatan dengan metode penyuluhan dan pelatihan tentang manfaat serta cara pengolahan air kelapa menjadi kecap. Hasil dari pelaksanaan kegiatan ini adalah meningkatnya pengetahuan peserta tentang air kelapa, yaitu kandungan gizinya, dan produk olahannya berupa kecap. Hasil uji organoleptik menunjukkan tingkat kesukaan panelis terhadap rasa, aroma, tekstur dan warna menunjukkan hasil yang baik, dimana seluruh panelis menyukai produk kecap air kelapa.   Kata kunci: Air kelapa, kecap, organoleptik, Desa Mattirodeceng.

Abstract

Molecularly Imprinted Polymers (MIP) are polymers with active sites that can recognize target molecules selectively. This study aims to determine the kinetics and adsorption capacity of MIP_DBP. The method used in the synthesis of MIP_DBP was precipitation polymerization using methacrylic acid (MAA) monomer, Ethyleneglycol Dimethacrylate (EGDMA) cross linker, DBP as a template molecule, and toluene as a solvent. The MIP_DBP obtained is a white solid. The results of the MIP_DBP adsorption kinetics test followed the pseudo-second-order kinetics model and the adsorption capacity according to the Freundlich isothermal adsorption model with the adsorption capacity value for DBP was 9.38 mg/g.
