Abstract

Danau Sadar Village is a village located in the sub-district of Dusun Selatan, 8 km from Buntok, the capital of South Barito Regency. This village has several potentials such as rubber plantation, livestock sector, tourism, and fisheries sector. Even though this potential is quite remarkable, the citizen welfare is still in low catagories due to the lack of skill in managing it. This condition happened because not all workers are engaged in the production process. Related to the condition of the community in Danau Sadar Village, an idea emerged to empower the community, by providing training to improve their skills. The objectives of community service in Danau Sadar Village are as follows: (1) assisting the people of Danau Sadar Village in developing economic independence; (2) improving entrepreneurial skills through the training provided. The community service program has been successful by carrying out two types of training activities to improve citizen welfare: training on biogas reactors from manure and brick making to obtain optimal products in terms of production costs and quality. The citizen in Danau Sadar Village welcomes this community service program. They hope that Palangka Raya University will carry out the community service program regularly in their village.

Abstract

Clay is a natural material from crystalline silicate with layered structures, has high cation exchange capacity, and large surface area. These advantages can be used as an adsorbent for the removal of contaminants in aqueous solutions, such as heavy metals and dyes. In Indonesia, clays from Java, Sulawesi, and Sumatra islands have been used as adsorbent, furniture, and construction materials. Due to limited information about basic characteristics of clay from Kalimantan, this clay has not been utilized well. Therefore, natural clay from Kalimantan, especially in Central Kalimantan, was used as adsorbent of cationic dyes in this present study. However, the clay has difficulty for separating the solid phase from aqueous solution after adsorption process. To solve this problem, combining clay with magnetic material was opted. The objectives of this study are to synthesize the magnetic composite material from natural clay by coprecipitation method and to characterize the synthesized magnetic composite material using an x-ray diffraction method, transmission electron microscopy, and vibrating sample magnetometer. The adsorption properties of the synthesized magnetic composite material were evaluated using rhodamine B and methylene blue dyes in aqueous solution. Before magnetic composite material was synthesized, the clay was previously being activated for removing impurities. The magnetic material formed in the structure of clay had magnetite with particle size of 2.75 nm and the magnetization value of 24.91emu/g. The adsorption capacities of natural clay, activated clay, and magnetic composite of clay in rhodamine B were 34.29, 76.27, and 81.46 mg/g, respectively, while in methylene blue were 30.25, 83.92, and 133.90 mg/g, respectively. These results suggested that magnetic composite of clay can increase the adsorption capacities against dyes and accelerate the separation of the adsorbent solid phase from aqueous solution with largest adsorption capacity on methylene blue dye.
