Kemampuan chitosan untuk mengikat besi dapat diketahui dengan cara mengukur kadar ferritin serum dan deposit besi jantung pada tikus putih wistar (Rattus norvegicus) jantan model iron overload. Metode yang digunakan pada penelitian ini adalah eksperimen laboratorium in vivo. Tiga puluh (30) ekor tikus wistar jantan dibagi menjadi 6 kelompok, yaitu kelompok normal (N) diberi makanan standar dan tanpa perlakuan tertentu, kelompok control negative (K-) diberi makanan standar dan diinjeksikan iron sucrose 75 mg/KgBB selama lima minggu (3x seminggu) secara intraperitoneal. Kelompok perlakuan terdiri dari P1, P2, P3 diinjeksikan iron sucrose 75mg/kgBB selama lima minggu (3x seminggu) serta diberikan tambahan perlakuan yang berbeda. Selain diberikan makanan standar, kelompok P1 diberikan chitosan secara oral 16 mg/KgBB/hari, kelompok P2 diberikan chitosan secara oral 32 mg/KgBB/hari, sedangkan kelompok P3 diberikan chitosan oral 64 mg/KgBB/hari. Kelompok control positif (K+) pada penelitian ini diinjeksi iron sucrose dan diberikan deferiprone 75mg/KgBB/hari secara oral. Hasilnya menunjukkan bahwa pemberian chitosan 16mg/KgBB/hari yang diberikan secara oral tidak memiliki perbedaan secara signifikan (p>0,05) dari pemberian deferiprone oral dalam menurunkan kadar ferritin serum dan deposit besi jantung.

This research studies the influence of the type of rubber seed that is superior and local, altitude plant in South Sumatra province to the characteristic of seed, oil and biodiesel (methyl ester). Rubber plants planted from local rubber seed by seeds seedlings and superior rubber seed by selected clones. In the study, rubber plants planted at a different altitude, namely in Banyuasin district (18 m above sea level), Prabumulih District (176 m above sea level) and Lahat District (627 m above sea level). The results showed that the weight of the flour, the water content and ash content in the local rubber seeds larger than the superior rubber seed for all altitude, but oil content a large in the superior rubber seeds. The major of fatty acids in the rubber seed oil in all types and altitude are a linoleic acid with a different percentage except local rubber seed oil from Lahat district with the large percentage of octadecanoic acid. Free fatty acids in the oil from the superior seeds rubber of 13.897-15.494 % large than local rubber seed oil was found 9.786-10.399 % for all altitude. By esterification process using sulfuric acid catalyst, Free Fatty Acid (FFA) can be reduced to â‰¤ 2 %. The methyl ester made from the transesterification process of rubber seed oil after esterification using methanol and sodium hydroxide as catalyst. Analysis of methyl esters includes cetane index, flash point, kinematic viscosity, carbon residue, density, moisture content, water and sediment content and distillation compared with SNI 7182 and ASTM 6751-02.Â The result indicated that the quality of methyl ester from superior rubber seed oil in the Banyuasin and Prabumulih district better than another methyl ester. The types of rubber seed altitude affect the characteristics of the seed, oil and methyl esterÂ but the altitude are not significantly different.Keywords: rubber seed, type, altitude, oil, biodieselArticle History: Received March 21st 2017; Received in revised form May 5th 2017; Accepted June 2nd 2017; Available onlineHow to Cite This Article: Salni, S, Hariani, P.L. and Marisa, H.

Burai village is located in Tanjung Batu sub-district, Ogan Ilir district. Burai Village is a tourism mainstay village in Ogan Ilir district. This village is known as the colorful village. As an ecotourism destination, water tourism and fishing programs have been developed, as well as environmentally friendly fish farming through organic feed. Other tourism potentials, such as the existence of traditional Bari houses that are more than 200 years old, and songket crafts. As patients with the COVID-19 virus have decreased, the number of tourists visiting Burai village has also increased. Health protocols are still needed, one of which is the use of hand sanitizer. This community service activity is to provide training on making liquid hand sanitizer from lime peel extract with the target audience being the Burai village community, especially tourism service providers. Lime plant is one of the plants cultivated by the people of Burai village. Orange peel extract contains essential oils that function to inhibit the growth of bacteria. In addition, orange peel extract has a fresh aroma. Activities are carried out by giving lectures, training on making hand sanitizers and packaging them. With this activity, it is hoped that the community will be able to provide hand sanitizers for both their own needs and tourists. The results of the activity showed high community participation in activities, more than 75% of the target audience liked the aroma of lime peel extract hand sanitizer.

Bagasse is the solid waste derived from the sugar-making process. A large amount of silica in bagasse is a potential source of silica. In this study, extraction of silica from bagasse was carried out in the following steps: pretreatment of bagasse using HCl solution, followed by calcination at varying temperatures (700℃, 800℃, and 900℃) using a furnace. Furthermore, extraction using NaOH solution and precipitation using HCl. Silica characteristics were obtained using X-Ray Diffraction (XRD), Scanning Electron Microscopy-Electron Dispersive Spectrometry (SEM-EDS), and BET surface area. The results showed that calcination temperature affected the characteristics of the silica produced. The silica extracted at 700℃ produced an amorphous phase with a broad peak at an angle of 2θ = 20-24°. It contained the most considerable silica content and surface area, 42.46% and 796.89 cm2/g, respectively. The extracted silica had an average diameter of 5.67 mm and a pore volume of 1.184 cm3/g.

The iron oxide (Fe3O4) nanoparticles modified with polyethylene glycol (PEG) was synthesized by co-precipitation methods using ferric and ferrous ions as the precursors. Further, the antibacterial activity was performed against gram-positive and gram-negative bacteria. The Fe3O4-PEG was characterized using X-Ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), Scanning Electron Microscopy (SEM) with energy dispersive X-Ray analysis (EDAX) and Vibrating Sample Magnetometer (VSM). The particle size of Fe3O4-PEG calculated using XRD is 46.2 nm. The study confirmed that Fe3O4-PEG is superparamagnetic and has a saturation magnetization of 56.43 emu/g. The prepared Fe3O4-PEG gives the effect of both gram-positive and gram-negative pathogenic bacterial strains hence this material has potential utilization in the field of pharmaceutical and biomedical in the future.

Snakehead Fish Bone (SFB) is a waste from food processing in Palembang. Fish bones have calcium content so they have a potential as a source of Calcium Oxide (CaO). Calcination of fish bones was carried out at a temperature of 900oC with variations of time 1, 2, 3, and 4 hours. The Nanoparticle Calcium Oxide (NCO) was prepared using the ball milling method. This study aims to make NCO as a raw material for hydroxyapatite synthesis. The NCO was characterized using Fourier Transform Infra-Red (FTIR), X-Ray Diffraction (XRD), and Scanning Electron Microscope (SEM). Characterization using FTIR shows that NCO has functional groups O-H, CO32- and PO43- functional groups. XRD analysis shows that NCO has an average particle size of 38.9445 nm.Analysis using SEM shows particles in the form of granules of almost uniform size. The NCO produced eligible of the nanomaterial and has the potential as a raw material for synthesis of hydroxyapatite.Keywords: Nanomaterial, ball milling, calcium oxide, fish bone
