Abstract

This training activity aims to enhance the knowledge, insights, and skills of the community regarding external medicines, specifically the skills to make liquid balm that is beneficial for health. Additionally, this activity aims to foster entrepreneurial interest among the community through home-based businesses that can increase family income. The activity is centered in Lubuk Sukon Village, Ingin Jaya District, Aceh Besar Regency. The targets of this training activity are housewives and teenage girls who spend most of their time taking care of their households and families. To facilitate this training activity, brochures about the materials and procedures for making balm, the ingredients used, introductory theory, and tips for making balm were distributed to the target community. Furthermore, demonstrations and hands-on practice in making balm were provided, resulting in products that can be used personally or become a business idea.

Abstract

Oksidasi parsial metana menjadi metanol dan formaldehida menggunakan katalis tembaga molybdenum oksida berpenyangga silica (CuMoO3/SiO2) telah dilakukan. Preparasi katalis dilakukan dengan metode impregnasi. Hasil identifikasi dengan XRD menunjukkan bahwa komponen katalis terdiri dari senyawa MoO3, CuO, dan SiO2. Uji kinerja katalis dilangsungkan dalam reactor pipa lurus berunggun tetap, beroperasi pada temperature 400, 425, 450, 475, dan 500oC, dengan waktu tinggal (W/F) 5,82, 9,7, dan 14,55 gram katalis jam/mol. Produk reaksi dianalisis menggunakan gas kromatografi dengan kolom molsieve 5A dan porapak-Q. konversi metana tertinggi sebesar 36,83% diperoleh saat menggunakan katalis dengan rasio Cu:Mo=1:1,5 pada W/F 14,55 grcatjam/mol dan temperatur reaksi 500oC. Selektivitas metanol tertinggi diperoleh 11,19 % menggunakan katalis dengan rasio Cu : Mo 1 : 3,5 pada W/F 5,82 grcat.jam/mol dan temperatur reaksi 400oC. Selektivitas formaldehida tertinggi diperoleh 20,75% menggunakan katalis dengan rasio Cu : Mo 1 : 2,5 pada W/F 9,7 grcatjam/mol dan temperatur reaksi 400oC.Keywords: formaldehida, katalis CuMoO3/SiO2, metanol, oksidasi metana
