Publisher : Faculty of Mathtmatics and Natural Sciences

Penjelasan tentang pengaruh proses pengukusan terhadap daya awet rendang daging sapi yang dikemas telah dilakukan. Produk rendang dikemas dalam plastik tahan panas dan pengukusan dilakukan selama 60 menit. Penelitian dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL), dengan 8 taraf lama penyimpanan yaitu 0, 1, 2, 3, 7, 14, 21, 28 dan 35 hari. Analisis nilai gizi produk rendang meliputi kadar air, kadar lemak dan kadar protein. Uji organoleptik juga dilakukan untuk mengetahui tingkat kesukaan panelis terhadap produk rendang yang dikukus dan disimpan. Dari analisis keragaman terhadap kadar air, lemak dan protei, menunjukkan bahea perlakuan pengukusan memberikan pengaruh nyata (P<0,05), tapi berdasarkan uni beda nyata jujur (BNJ) antara setiap perlakuan sebagian besar menunjukkan perbedaan yang tidak nyata, ini menunjukkan bahwa proses pengukusan cukup baik untuk mempertahankan mutu rendang daging sapi.

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.

Alumina-activated carbon composite has been synthesized and studied for adsorption procion red dye. Composite was prepared by precipitation method aluminium hydroxide on the surface of activated carbon followed by calcinations. The Fourier transform Infra Red (FTIR), Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy (SEM-EDS) and Brunaeur Emmet Teller (BET) surface are being used to characterize the adsorbent. Batch adsorption experiments were carried out for the adsorption of procion red dye. Effect of the mass of composite, stirrer speed, contact times and pH of the solution on the adsorption capacity were studied. The obtained optimum conditions applied to adsorp of procion red dye from wastewater songket industry. The result showed that the adsorption optimum at mass of alumina-activated carbon composite 0.1 g, stirrer speed 150 rpm, contact times 2 hours at pH of the solution 9. The adsorption isotherm data according to Langmuir isotherm. The alumina-activated carbon composite can be removal of procion red dye from wastewater songket industry with effectiveness adsorption of 88.21 %.

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.
