Abstract

Abstrak. Mendoan adalah makanan khas masyarakat Banyumas yang berbahan dasar tempe. Bagi masyarakat Banyumas makan mendoan itu sudah merupakan budaya setiap hari. Tiada hari tanpa makan mendoan. Untuk membuat mendoan yang mudah dan cepat diperlukan tepung yang praktis/instan/siap pakai. Produksi tepung mendoan instan dalam skala rumah tangga sangat terbatas dan selalu kewalahan melayani permintaan konsumen. Setiap hari hasil produksinya habis terjual, bahkan sampai menolak pesanan.. Untuk mengatasi permasalahan-permasalah tersebut tim pengabdian masyarakat Universitas Jenderal Soedirman dan Universitas Peradaban berusaha untuk membantu meningkatkan kapasitas produksi dengan cara memberikan bantuan alat-alat produksi. Selain itu juga akan dilakukan pendampingan, penyuluhan dan pelatihan meliputi: penggunaan dan perawatan alat-alat modern.

Abstract

The non-edible oil from nyamplung seed (Callophyllum inophylum L.) has been widely used as a soap ingredient. The soap production from nyamplung seed oil with the addition of antioxidant and fragrance had been carried out in this research. Ketapang (Terminalia catappa L) fruit extract and Cardamom (Amomum compactum) were used as antioxidant and fragrance substances, respectively. The variation of concentration of antioxidant and fragrance has been carried out to obtain the high quality of soap. Characterization was done to know the quality of soap in accordance with SNI 06-4085-1996. The antioxidant activity was analyzed using DPPH (1,1-diphenyl-2-picrylhydrazyl). The results showed that the addition of 1% ketapang fruit extract and 3% cardamom fragrance exhibited the best characteristics. The antioxidant activity test showed that the IC50 value of the best antioxidant soap is 79.51 ppm, indicating that the soap is a strong category

Abstract

The Ag3PO4 photocatalyst has been developed to degrade the organic pollutant due to its highly active responsive under visible light irradiation. The properties of Ag3PO4 may depend on design and preparation. Starting materials and co-precipitation conditions would significantly affect the properties of the product. The controlled defect of this photocatalyst may lead to improve catalytic activity. Here, the unique properties of phosphate deficiency in Ag3PO4 were created using the starting material of KH2PO4 and AgNO3 under a mixed solvent of water and ethanol. AgNO3 solution with the ethanol percentages of 0%, 25%, 50%, 75% and 90% was added to KH2PO4 aqueous solution. The photocatalysts were characterized using XRD, DRS, SEM, and XPS. The changes in morphology can be observed from the tetrahedral to the sphere which has smaller particles. The increased atomic ratio of Ag/P and Ag/O suggests that the silver ion enrichment in Ag3PO4 has been created. The activity of Ag3PO4 for Rhodamine B elimination increased by 4.3 times higher compared to that of the pristine Ag3PO4. The enhanced photocatalytic activity might be caused by the smaller particle size and higher silver ion content on the surface of Ag3PO4.
