Abstract

Silica gel can be used as an absorbent so that it can also be used as a process for making eugenol-silica gel composites. This study aims to optimize the adsorption of the eugenol-silica gel composite to Cu (II) metal ions and to determine the maximum absorption capacity and adsorption constant of the Langmuir and Freundlich isotherm model. This research begins with determining the optimization of contact time 10-60 minutes, temperature 20-45 oC and the weight of the adsorbent is carried out in the range of 0.10-0.20 grams in a 50 mL solution and the experimental design of the box Behnken method will determine three variables through (Response Surface Methodology). Furthermore, the determination of Cu levels by preparing 100 ppm Cu mother liquor, making a standard series, and testing with Atomic Absorption Spectroscopy (AAS), and then determination of Langmuir and Freundlich adsorption isotherms. The results showed that the optimum conditions for the adsorption process using Response Surface Methodology (RSM) were at a contact time of 30 minutes, a temperature of 45 oC with an adsorbent weight of 0.10 grams in a 50 mL solution, in Langmuir and Freundlich isothermal adsorption. The adsorption process takes place in two directions (reversible) the values of Kf, b and n are 8331; -5.2224 and -0.4541.

Abstract

Mitra yang terlibat dalam kegiatan Pengabdian pada Masyarakat ini adalah SMP Bina Dakwah Leuwiliang Bogor. SMP Bina Dakwah merupakan suatu lembaga non-profit yang bergerak di bidang pendidikan. Masyarakat kelompok ini kami jadikan sebagai mitra untuk diberikan keterampilan membuat sabun cuci piring dengan harapan keterampilan ini mampu mengangkat masyarakat untuk berkarya dan menjadi masyarakat yang produktif sehingga dapat meningkatkan kesejahteraan ekonomi. Pelaksanaan program ini dilakukan melalui pelatihan keterampilan pembuatan sabun cuci piring untuk skala industri rumah tangga secara detail, kontinyu dan tuntas sampai dihasilkan produk sabun cuci piring dengan kualitas yang baik. Selain itu, dilakukan pelatihan pengemasan dan pelabelan produk sabun cuci piring dalam kemasan. Pelatihan dilanjutkan dengan pembinaan serta pendampingan mitra dalam memulai membuat jaringan pemasaran ke berbagai pihak yang membutuhkan produk sabun cuci piring ini. Jenis luaran yang akan dihasilkan dari program pemberdayaan masyarakat non produktif melalui keterampilan membuat sabun cuci piring ini adalah model pemberdayaan masyarakat, mencakup terbukanya wawasan masyarakat non-produktif mengenai peluang usaha pembuatan sabun cuci piring, menghasilkan tenaga-tenaga terampil, menghasilkan produk sabun cuci piring yang berkualitas baik dan siap untuk dipasarkan dan membuka peluang untuk direkomendasikan menjadi usaha kecil mandiri yang lebih potensial sehingga dapat meningkatkan pendapatan masyarakat yang berimbas pada peningkatan kesejahteraan.

Abstract

Water is an important natural resource for human survival. Groundwater in calcareous soil areas contains high levels of Ca(HCO3)2 and Mg(HCO3)2 salts and will have a negative impact if consumed continuously. In this study, an adsorption method using tea waste (Camellia sinensis) was conducted to reduce the concentration of Ca(II) ions that cause water hardness. Tea waste was activated with 0.1 N HCl for 24 hours. Tea waste was characterized by Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). Determination of optimum conditions was carried out at pH variations of 4, 6, and 8, with contact times of 30 minutes, 60 minutes and 90 minutes, and adsorbent weights were 0,5 grams, 1 gram, 1.5 grams and 2 grams. Tea waste with the best optimum conditions was tested on Ca(II) solutions of various concentrations from 30, 50, and 70 mg/L respectively to determine the maximum capacity for Ca(II) metal ions and the type of adsorption isotherm. Then applied to well water samples analyzed by Inductively Coupled Plasm (ICP) to determine the capacity of Ca(II) that can be absorbed by each adsorbent. The results showed that to utilize 0.1 N HCl-activated tea waste as an adsorbent for Ca(II) metal ions were optimum at pH 8, with a contact time of 30 minutes and an adsorbent weight of 0.5 grams. The maximum adsorption capacity was obtained at Ca(II) solution concentration of 70 mg/L with an adsorption capacity value of 6.704 mg/g. The adsorption isotherm corresponding to the tea waste adsorbent is the Freundlich isotherm (r2 = 0.9199). The highest absorption of Ca(II) metal ions in well water samples from the concentration of Ca(II) metal ions was 72.7702 mg/L to 4.877 mg/L, with adsorption efficiency of 93.3% and adsorption capacity of 6.7893 mg/g.
