Analysis of Internal Control in the Distribution of Agricultural Business Credit

Library research, namely the authors collect data related to the theory of financing or lending to economically weak entrepreneurs. Field research, namely field research activities, in which the author looks for data that is the object of research, to obtain data the author conducts local observations and direct interviews with the leadership. Observation techniques were carried out by conducting direct observations in the process of distributing credit to economically weak entrepreneurs. Based on the description above, so the authors chose the title "Analysis of Internal Control in Distribution of Farmers Business Credit"

Subalgebra Bases in Local Rings and its Efficient Computation in Polynomial Rings

In Chapter 1, there are given some necessary definitions and results about monomial orderings, Standard basis and Sagbi basis in polynomial ring over the field along with a description on the Gr ̈obner walk algorithm and Gr ̈obner basis under composition. In Chapter 2 we develop a theory of subalgebra basis analogous to Standard basis for ideals in polynomial rings over a field. We call this basis Sasbi Basis, standing for Subalgebra Analogue to Standard Basis for Ideals. Sasbi bases may be infinite. In this chapter we consider subalgebras admitting a finite Sasbi basis and give algorithms to compute them. Sasbi basis theory is given in my paper [22]. In Chapter 3, we present an algorithm which converts the Sagbi basis with respect to one ordering to the Sagbi basis with respect to another ordering, under the as- sumption that the subalgebra admits a finite Sagbi basis with respect to all monomial orderings. We called it Sagbi walk algorithm. Sagbi Walk algorithm is given in my paper [20]. Composition is an operation of replacing variables in a polynomial by other poly- nomials. In Chapter 4, we study the behavior of Sagbi basis under composition. Some related results are from my paper [21].
