ARTICLE DETAILS ABSTRACT Article History: Received 16 February 2021 Accepted 24 March 2021 Available online 01 April 2021 The increase in the need for animal-based food consumption creates opportunities in the development of cattle farming in the future. But the problems in the field are a decrease in livestock productivity such as a decrease in livestock population and a decrease in livestock body weight, this is due to the lack of availability of sustainable animal feed. The solution offered is to use food crop waste as an alternative feed for livestock, so it is necessary to analyze the carrying capacity of food crop waste in an area. The purpose of this research is to analyze the potential resources of beef cattle feed based on food plant waste in West Sumatra Province and to analyze the nutritional content of food plant waste. The research was conducted in West Sumatra Province in January 2021. The method used was literature study and secondary data analysis. The data required consists of: (1) food crop production data, (2) beef cattle population data in West Sumatra Province. Data were analyzed by analyzing the carrying capacity of food plant waste. The results showed the availability of feed in West Sumatra Province 728,195.32 tonnes BKC / year, while the current total feed requirement is only 410,159.32 tonnes BKC / year. This shows the large potential for feed that has not been utilized, and this means that there is a large opportunity for Prov. West Sumatra in the future development of ruminants. The carrying capacity index of food plant waste (IDD) is 2.37, which means that it has a safe status where food plant waste is able to help support the needs of animal feed in West Sumatra Province. To increase the nutritional value of food plant waste, it can be overcome by giving a touch of waste processing technology innovations such as fermentation, silage, or ammonia. The results of this study are important as recommendations for the government regarding the sources of information on areas that have the potential to develop livestock business, which can be seen from the status of the area's carrying capacity index or the potential availability of abundant animal feed.

INTRODUCTION In developing a beef cattle business in an area, there are several things of concern, including human resources, natural resources, and quality and sustainable animal feed resources. what is often an obstacle is the diminishing source of animal feed. In an area of livestock development, it often fails to increase the livestock population because it is less in analyzing the carrying capacity of the area such as the availability of space for livestock and the carrying capacity of the availability of animal feed. There are many inhibiting factors in the provision of food, including the climatic factors of an area that will affect forage growth such as in the dry season the amount of forage is much reduced compared to the rainy season. In addition, there is a change in land function which was previously land as a source of food, such as pasture changing functions as residential land industry and agricultural land to meet the food supply due to the increasing population (Moniaga, 2011). At this time, the amount of intensification in the development of food crops in West Sumatra is an opportunity to overcome the lack of grass as a source of forage by utilizing agricultural waste from food crops. Syamsu states that the source of agricultural waste as an alternative source of feed for livestock is obtained from food plant commodities (Syamsu, 2011). Types of food crop waste that can be used as a source of feed are rice straw, corn straw, peanut straw, cassava shoots, soy straw, and sweet potato straw. Animal husbandry actors need to know the potential of food crop waste-based animal feed resources to support the development of beef cattle (Salami et al., 2019; Jabemat, 2018). This is also in accordance with the statement from some study (Maryono and Romjali, 2007; Tafsin, 2018). that basically the main feed for beef cattle is in the form of forage amounting to 60-70% of the total daily need for animal feed, but in reality in the field that there are limitations in the fulfillment of forage, the solution is for the development of animal husbandry, namely by integrating in the form of optimizing the use of agricultural waste from food plants as animal feed. The purpose of this study is to analyze the potential resources of beef cattle feed based on food plant waste in Prov. West Sumatra and to analyze the nutritional content of food plant waste.
