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

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

Berdasarkan survei, pengetahuan masyarakat tentang bahaya formalin dan cara mendeteksinya masih terbatas karena pengujian formalin biasanya memerlukan laboratorium. Untuk itu, pelatihan diberikan dengan memanfaatkan kulit buah naga sebagai bahan alami yang sederhana dan mudah diakses. Program pengabdian masyarakat ini bertujuan meningkatkan kemampuan ibu-ibu di Majelis Taklim Permata Babul Maghfirah, Majene, dalam mendeteksi kandungan formalin pada bahan pangan secara mandiri. Kegiatan ini meliputi beberapa tahapan: persiapan melalui komunikasi dengan mitra, pelaksanaan berupa penjelasan teknik deteksi formalin dan eksperimen langsung, serta monitoring dan evaluasi untuk mengukur keberhasilan pelatihan. Hasilnya menunjukkan peningkatan pemahaman dan keterampilan peserta hingga 80%. Peserta mampu melakukan metode deteksi sederhana secara mandiri dan mengidentifikasi bahan pangan yang dicurigai mengandung formalin. Kesimpulannya, pelatihan ini berhasil meningkatkan pengetahuan dan keterampilan praktis peserta dalam mendeteksi formalin menggunakan bahan alami. Metode sederhana ini terbukti efektif dan mudah diterapkan dalam kehidupan sehari-hari. Disarankan agar program serupa diperluas dengan memanfaatkan bahan alami lain untuk mendeteksi zat berbahaya serta melibatkan peserta yang lebih beragam, termasuk laki-laki dan generasi muda, guna meningkatkan kesadaran dan keterampilan masyarakat secara luas.

Abstract

This paper is aimed to solve fractional integral equations using fixed point iterative approach. We used D-plus iteration process with nonexpansive mapping in uniformly convex Banach spaces. We start by prove weak and strong convergence theorems related for nonexpansive mapping and compare convergence rate of some iterative scheme through numerical example. Furthermore, we use this method to prove the existence and estimate the solution of fractional integral equations. The D-plus iterative method shows the good performance in solve fractional integral equations. We also give some example to illustrate main results.

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

A seminear-ring is a generalization of ring. In ring theory, if is a ring with the multiplicative identity, then the endomorphism module is isomorphic to . Let be a seminear-ring. Here, we can construct the set of endomorphism from to itself denoted by . We show that if is a seminear-ring, then is also a seminear-ring over addition and composition function. We will apply the congruence relation to get the quotient seminear-ring endomorphism. Furthermore, we show the relation between c-ideal and congruence relations. So, we can construct the quotient seminear-ring endomorphism with a c-ideal.
