Biodegradable foam is an alternative to styrofoam packaging which is not environmental friendly and harmful to health. Various sources of starch are widely available in nature which can be used as raw material for making biodegradable foam. Several researchers found that many types of starch can be used as the main material for making biodegradable foam, including cassava starch, corn starch, sago starch, durian seed starch, jackfruit seed starch, avocado seed starch, and banana weevil starch. The production methods used from several studies that have been carried out are thermopressing, baking process, microwave assisted molding, and extrusion. Biodegradable foam based on starch is brittle, sensitive to water and requires additional treatment to increase strength, flexibility and resistance to water so that it can be used commercially. The purpose of this article is to provide information on the production of biodegradable foam from various types of starch and cellulose. Based on the results of the analysis, the characteristics of biodegradable foam using the baking process method and modified sago starch resulted in better water absorption values compared to other types of starch and production methods.

PENGARUH MINUMAN BEROKSIGEN TERHADAP SISTEM IMUN, KADAR MALONALDEHIDA DAN PERFORMA RESPONDEN MAHASISWA OLAHRAGAWAN[Effect of Oxygenated Water on Immune System, Malonaldehyde Content and Student-Athlete Performance]Cesar Welya Refdi, Fransiska Rungkat Zakaria* dan Puspo Edi GiriwonoDepartemen Ilmu dan Teknologi Pangan, Fakultas Teknologi Pertanian, Institut Pertanian Bogor, Bogor Diterima 23 Agustus 2013 / Disetujui 01 Juli 2014ABSTRACT Exercise requires more oxygen input and cannot be fully obtained through breathing. The body has a homeostatic system, when more ATP is needed, the more oxygen is required by the body. Limited supply of oxygen such as those happens in athlete’s body automatically switches the respiration from aerobic into anaerobic. This situation results in building up of lactic acid which in turn lowers the energy for cellular metabolism as well asenergy for exercise. The purpose of this study was to assess the effects of short-term and long-term drinking of oxygenated water on lactic acid and energy expenditure (EE) in exercise performance; Cluster of Differentiation-4 (CD4), CD8, CD56, Interleukin-6 (IL-6) contents; and level of malonaldehyde. During short-term intervention, 12 male student volunteers drank oxygenated (50, 80 and 130 ppm) water and normal mineral water, 15 minutes before treadmill and after treadmill (10 Kmh). The lactic acid concentration was measured before and after treadmill, and 5 minutes after the reconsumption of the oxygenated water. During long-term intervention, 17 male student volunteers drank oxygenated (100 ppm) water twice a day for 21 days. The blood plasma and lymphocyte sampled before and after intervention were analyzed for the same parameters. The results showed that oxygenated water had no effect on lactic acid accumulations and EE. Similarlyt he long-term study showed that oxygenated water did not affect CD4 and CD8, had no harmful effect on IL-6 and malonaldehyde, yet it significantly increased the CD56 content.

There is still a lack of knowledge of Andalas University inventors on the importance of the Innovation Readiness Level (KATSINOV), which is a tool to measure the level of innovation. Therefore, it is necessary to hold socialization to the inventors and SMEs of Padang City to provide information about the importance of this KATSINOV. This socialization activity was carried out through a zoom meeting by inviting experts in this field. The method used is the presentation method, namely by providing socialization about KATSINOV to the inventors and tenants of Andalas University. In addition, the methods used were observation and direct interviews with Andalas University inventors to identify and measure KATSINOV's respective products. Socialization was provided by resource persons who understand KATSINOV. Katsinov is organized into six levels and seven key aspects covering technology, market, organization, partnership, risk, manufacturing and investment. This socialization activity resulted in the measurement of the level of product innovation readiness of Andalas University research. Furthermore, it was necessary to design a website-based application to facilitate the measurement of KATSINOV research products and West Sumatra MSME products.

Activities intended for Micro, Small and Medium Enterprises (MSMEs) in West Sumatra in obtaining Halal product certificates. The activity began with socialization and registration by MSMEs for products to be registered for halal certification. MSMEs, which are generally engaged in food processing, lack knowledge of the importance of product legality. The need to obtain product certification is demanded by increasing market competition and public awareness of the importance of the safety of a product they consume. In addition, the lack of knowledge of small business actors about the procedures that must be passed is also a significant problem. So, the implementation of this activity is significant in increasing the competitiveness of partner products. This community engagement activity aimed to help partners in product and business development and become partner facilitators to obtain product Halal certificates.

This community engagement activity has located a centre for horticultural agriculture, such as fruits and vegetables, in Nagari Padang Laweh, Sungai Pua district and Agam regency, West Sumatra Province. The focus products were tomato and oyster mushrooms at the time. Besides a farmer's land for tomatoes, there is also an oyster mushroom business managed by Hoki Jamur, producing 5-7 kg of fresh mushrooms per day. The problems faced by the partner's activity were a lack of processing technology for horticultural products. Tomatoes often through away when the price is low in the market. The production of oyster mushrooms is still fluctuating because cultivation is not good enough, and oyster has high water content, so it is easy to rot and have a short shelf life. Activities that have been carried out to solve partner problems were first evaluating horticulture and oyster mushroom cultivation activities at partner locations. Then, introducing processed post-harvest of horticulture to increase the selling value and its diversification to increase the shelf life of products by making tomato sauce and oyster mushroom meatballs. This activity went well and smoothly and was attended by local farmers, members of the Family Welfare Movement (PKK), and young entrepreneurs. Participants' enthusiasm for participating in this activity was high, especially during post-harvest product processing technology. This activity is expected to improve the quality and quantity of business production, income and economic welfare of partners and communities involved in partner business activities.
