Abstract

Let commutative Semiring S. Ideal on Semiring S defined in the same way with the Ideal on the ring. On Semiring  there are special Ideals such as -ideal, -maximal Ideal and -ideal. Semiringwith a unique -maximal Ideal is called local Semiring. In This paper we will discussed that from non negative integer  we can determined a local Semiring and quotient Semiring.

Abstract

Let R commutative ring with multiplicative identity, and M is an R-module. An ideal I of R is irreducible if the intersection of every two ideals of R equals I, then one of them is I itself. Module theory is also known as an irreducible submodule, from the concept of an irreducible ideal in the ring. The set of R - module homomorphisms from M to itself is denoted by EndR(M). It is called a module endomorphism M of ring R. The set EndR(M) is also a ring with an addition operation and composition function. This paper showed the sufficient condition of an irreducible ideal on the ring of EndR(R) and EndR(M)

Abstract

Permasalahan yang sering ditemui dalam analisis pengelompokan adalah data yang berskala campuran numerik dan kategorik. Metode yang seringkali dilakukan untuk pengelompokan data berskala campuran adalah dengan mentransformasi data kategorik menjadi data numerik atau sebaliknya. Selain pengelompokan dengan metode transformasi tersebut, dikembangkan sebuah metode pengelompokan ensembel untuk data campuran. Pengelompokan ensembel adalah teknik pengelompokan untuk menggabungkan hasil pengelompokan beberapa algoritma pengelompokan dengan tujuan untuk mendapatkan hasil kelompok yang lebih baik, berdasarkan indeks validitas internal kelompok yaitu nilai SSW, Rata-rata koefisien Silhouette dan nilai Indeks Dunn yang dianalisis untuk 2,3  dan 4 Kelompok, diperoleh bahwa metode Ensembel Fuzzy lebih baik dan tepat digunakan pada data campuran yang ada pada penelitian ini daripada metode pengelompokan Ensembel ROCK.

Abstract

An academic article is acknowledged as a scholarly endeavour, encapsulating the research findings of academicians. These articles are conventionally disseminated through academic journals. In compliance with governmental directives, educators are required to draft and publish scholarly articles in such journals. To facilitate adherence to this mandate, the provision of training in academic article writing is imperative. This training aims to scrutinize and reconcile articles previously authored by educators with prevailing scholarly writing standards. The participants of this program were educators from MIS DDI Lapeo, with the goal of augmenting their proficiency in the composition of academic articles. This program saw the participation of 14 educators from MIS DDI Lapeo, encompassing both classical and individualized methodologies. The classical methodology entailed a structured training process in academic article preparation, commencing with an exposition on journals, articles, and the core principles of article creation, culminating in the actual drafting of academic articles. Conversely, the individualized approach was implemented in the context of one-on-one mentorship for article composition. The outcomes of this mentorship included an enhanced understanding among educators in the formulation of academic articles and an increased propensity towards engaging in article writing. Notable challenges encountered by these educators in the process of scholarly writing encompassed a paucity of references, constrained time allocations, and a lack of creative ingenuity, predominantly manifesting in their focus on Classroom Action Research.

Abstract

For many years, West Sulawesi's signature plant, banana pere, has only been eaten as fruit, while its peel is often discarded as waste or used as animal feed. This study provides information on the utilization of banana pere peel in order to increase its economic value through the utilization of pectin content contained in banana pere peel. This study aims to extract pectin from banana pere peel (Loka Pere) by using the citric acid solvent extraction method. The extraction process was carried out using 5 variations of time, namely 30, 60, 90, 120 and 150 minutes. The results showed that the use of extraction time for 90 minutes resulted in a yield value of 53.11%, moisture content of 1.15%, ash content of 1.56%, methoxyl content of 2.66% and galacturonic content of 30.88%.

Abstract

Assumed that (S,+,.) is a semiring. Semiring is a algebra structure as a generalization of a ring. A set I⊆S is called an ideal over semiring S if for any α,β∈I, we have α-β∈I and sα=αs∈I for every s in semiring S.  Based on this definition, there is a special condition namely prime ideal P, when for any αβ∈P, then we could prove that α or β are elements of ideal P. Furthermore, an ideal I of S is irreducible if Ia is an intersection ideal from any ideal A and B on S, then I=A or I=B. We also know the strongly notion of the irreducible concept. The ideal I of S is a strongly irreducible ideal when I is a subset of the intersection of A and B (ideal of S), then I is a subset of A, or I is a subset of B. In this paper, we discussed the characteristics of the semiring of the non-negative integer set. We showed that pZ^+ is an ideal of semiring of the non-negative integer Z^+ over addition and multiplication. We find a characteristic that 〖pZ〗^+  is a prime ideal and also a strongly irreducible ideal of the semiring Z^+ with p is a prime number.
