Rendang is a traditional Minangkabau cuisine with the main ingredient of beef or buffalo meat which is cooked using coconut milk and some spices. Rendang is cooked more than 2 hours, and after that do the repeated heating. This study aimed to determine the effect of repeated heating on fatty acid profiles of beef and spices of rendang. The analysis carried out at Chemistry Lab. and Biochemistry Lab. In Fateta Unand and Integrated Lab in IPB Bogor. This study designed used a completely randomized design with 5 treatments and 3 replications. The treatments that used in this study were A (raw beef), B (freshly cooked rendang), C (first heating), D (second heating), E (third heating) where the heating was done every 2 days. Data were collected for fatty acids profile of beef and spices of rendang. Analysis of the Type of Fatty Acid by HPLC method AOAC. The results shown that repeated heating of beef and spice of rendang had significantly different effect on the type of fatty acids and an increased trans fatty Acid of rendang.

Penelitian ini bertujuan untuk mengetahui pengaruh perbandingan oxtail dan ekstrak brokoli (Brassica oleracea, L.) terhadap karakteristik kaldu instan yang dihasilkan dan mendapatkan produk terbaik berdasarkan analisis sensori. Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri dari 5 perlakuan (perbandingan oxtail dan ekstrak brokoli A (100%: 0%), B (90%: 10%), C (80%: 20%), D (70% : 30%) dan E (60%: 40%)) dengan 3 ulangan. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan Duncan New Multiple Range Test pada α 5%. Pengamatan pada produk yang dihasilkan adalah analisis kadar air, kadar abu, kadar protein, kadar nitrogen amino, kadar lemak, kadar asam lemak bebas, aktivitas antioksidan, total karoten, natrium klorida, dan analisis sensori. Berdasarkan hasil analisis sidik ragam, perbedaan oxtail dan  ekstrak brokoli berpengaruh signifikan terhadap kadar air, abu, protein, nitrogen amino, lemak, asam lemak bebas, aktivitas antioksidan, total karoten, dan analisis sensorik. Produk terbaik dalam menghasilkan stok daging sapi instan terdapat pada produk dengan perbandingan oxtail 80% dan ekstrak brokoli 20% dengan karakteristik kadar air 9,59%, abu 11,56%, protein 3,84%, nitrogen amino 0,027%, lemak 0,52%, asam lemak bebas 0,92%, aktivitas antioksidan 60,88%, total karoten 0,85 mg / 100g, analisis sensorik terhadap warna (4,00), aroma (4,15), penampilan (3,65), dan rasa (4,00).

Kabupaten Dharmasraya yang terdapat hampir disepanjang jalan lintas Sumatera belum dikenal makanan khasnya. Makanan yang biasa dijadikan oleh-oleh hanya keripik tempe. Di Nagari Lubuk Besar terdapat produk olahan khas yang biasa disajikan pada acara-acara adat dan pernikahan, yaitu Atun. Sebagian ibu-ibu dari masyarakat Nagari Lubuk Besar hanya mampu menjual produk ini sesekali pada ‘hari pasa’ (jadwal pasar tradisional), karena permasalahan umur simpan produk yang singkat yaitu 1-2 hari. Hal ini juga yang menjadi kendala Atun dijadikan sebagai oleh-oleh khas Kabupaten Dharmasraya. Teknologi pengemasan vakum adalah sistem pengemasan hampa udara sehingga memperpanjang umur simpan, sehingga produk akan lebih bertahan 2-3 kali lebih lama daripada produk yang yang disimpan dengan nonvakum.Selain itu, pembuatan produk Atun Instan dapat bertahan lebih lama dan menjadi inovasi agar Atun dapat dikonsumsi oleh konsumen yang lebih jauh. Tujuan dari kegiatan IbDM ini secara umum adalah meningkatkan pengetahuan, keterampilan, kemandirian dan semangat berwirausaha bagi anggota kelompok Wanita “Lubuk Besar Bersinar” yang tergabung dalam Kelompok PKK Nagari Lubuk Besar dengan aplikasi teknologi. Dalam pengembangan produk atun ini dilakukan transfer teknologi dalam bentuk pelatihan teknologi pengemasan hampa dan penyimpanan, pembuatan atun instan, serta penyuluhan pemasaran dan manajemen bisnis Atun dalam mengembangkan produk Atun sebagai oleh-oleh khas Nagari Lubuk Kabupaten Dharmasraya. Kata Kunci: Atun, Atun Instan, Pengemasan Vakum, Makanan Tradisional ABSTRACT Dharmasraya District, located almost along the trans-Sumatra road, is not yet known for its traditional food. Food that is used as gifts is only tempeh chips. At Lubuk Besar Village, a village of Dharmasraya, there are typically snack usually served at traditional events and weddings, namely Atun. Some woman from the community of Nagari Lubuk Besar are only able to occasionally sell this product on 'Pasa Day' (traditional market schedule) because of the short shelf life of the product, which is 1-2 days. It also became Atun's obstacle as a souvenir of the Dharmasraya District. Vacuum packaging technology is a packaging system without oxygen that extends shelf life so that products will last 2-3 times longer than non-vacuum stored products. Additionally, Instant Atun products' production can last longer and become an innovation so that more distant consumers can consume Atun. This IbDM program aims to increase knowledge, skills, independence, and an entrepreneurial spirit for members of the "Lubuk Besar Bersinar" Women group and the Lubuk Besar PKK Group with the application of technology. In developing Atun product, technology transfer is carried out in the form of training on vacuum packaging and storage technology, making instant Atun, and counseling on Atun's marketing and business management in developing Atun products as souvenirs from Dharmasraya District.ogy, making instant Atun, and counseling on Atun's marketing and business management in developing Atun products as souv Keywords: Atun, Instan Atun, Vacuum Packaging, Traditional Food

Background: The corona pandemic has wreaked havoc all across the world, especially in Indonesia. Hand washing with soap or hand sanitizer is one approach to help prevent the transmission of the corona virus. To aid in the prevention of the corona virus, a variety of hand sanitizers have been developed.  Methodology: Therefore, hand sanitizers made from alcohol with lemon aroma have been produced and distributed to the community around the residence of the academic community of Andalas University. This hand sanitizer is made independently using ingredients such as alcohol, glycerin, water, hydrogen peroxide and lemon extract. Conclusion: The distributed hand sanitizer is highly accepted by the community because of the increasing need for personal hygiene due to the increasingly massive spread of the corona virus. It is hoped that this activity can be done continuously.
