Livestock management includes the systems of maintenance, reproduction, and waste utilization. This study aims to examine the potential of feed sources for ruminants (cows and buffaloes) and efforts to maintain continuous feed availability associated with ruminant livestock development strategies. The data used were primary and secondary data of feed sources. Furthermore, the variables observed include cattle and buffalo population, agricultural waste production, digested dry matter (DDM), and carrying capacity. The results showed that Seruway sub-district had the highest population of cattle with 8,378 cows (4,933 ST) or 20.35% while Karang Baru sub-district had the highest population of 70 buffalo (34 ST) or 40.23%. Meanwhile, Manyak Payed sub-district produced the highest agricultural waste with 5,029.32 DDM tons/year while the low district was Kuala Simpang city. Moreover, the commodity that produces the highest agricultural waste is rice which is scattered in all districts with a total of 19,370.65 DDM tons/year. Although the cassava plant was not in all districts, it has the potential of producing 48,154.5 tons/year DDM. Furthermore, the sub-district with a great opportunity was Karang Baru which produces an unutilized potential of 2,718.23 tons/year and a carrying capacity of 2,384.41 (ST/year). This showed that Kejuruan Muda subdistrict has insufficient agricultural waste for cattle and buffalo, therefore, breeders in this sub-district get feed from the plantation and other wastes. Based on the results, Aceh Tamiang district has the potential to increase the ruminants population by utilizing forage feed from agricultural waste.

The purpose of this study was to determine the capacity of agricultural crop waste for large ruminants Feed-in Bireun District. This research uses primary and secondary data sources. The observed variables consisted of beef cattle and buffalo population, production of feed crop waste, the requirement for digested dry matter (DDM), and the capacity of the DDM from food crop waste as large ruminant feed. The data is presented descriptively in the form of data processing results from secondary data with previous studies’ results. The beef cattle population in Bireun Regency is 38,151.44 livestock units (LU) and buffalo 1. 552 LU. The requirement of forage is 45,261.92 tons of DDM per year. DDM production per year from agricultural crop waste from rice, corn, and soybeans is 63,315.28 tons of DDM per year. The highest production of DDM is derived from rice crop waste amounting to 36,653.68 tons per year, while DDM originated from corn crop waste 3,637.5 tons per year and soybeans 23,024.1 tons per year. The potential of forage feed from food crop waste is 54,901.73 tons of DDM per year and can still be used for 48,159.41 LU. It was concluded that Bireun Regency could increase the population of ruminant animals by increasing the benefits of forage originating from food crop waste.

North Aceh District is one of the districts that produces ruminants and has great potential in the agricultural sector which will produce by-product so that it can be used as animal feed. The study was conducted from January to December 2018 in North Aceh district, Aceh Goverment. This study is a descriptive study. From the results of the study, it was found that the potential of agricultural by-product that could be used as feed was 5.145 rice (DDM / ton), peanuts 3.508, green beans 1.249, corn 261.530, cassava 146.332, soybean 145.420 and sweet potato 15. 077 (DDM / ton). Almost sub-districts have the potential for by-product from rice plants except for the Nisamsubdistrict. Baktiya Subdistrict is the largest producer of by-product from cassava, rice and sweet potato plants with a percentage of 12.43. The second place was followed by Sawang sub-district with potential by product from soybeans, cassava, corn, rice, and peanuts with a percentage of 9.23 and in third place was Tanah Jambo Aye sub-district with potential by-product from peanuts, cassava, soybeans, corn, sweet potatoes and rice. the percentage of 6.59 and finally the Geureudong Pase sub-district with the potential of cassava, peanuts, green beans, rice and corn with a percentage of 0.86. It can be concluded that with the increasing population of ruminants, it will require alternative feed obtained from agricultural byproduct which has potential in all sub-districts of North Aceh District.
