Abstract

Pengertian B-aljabar telah diperkenalkan oleh J.Neggers dan H.S.Kim di tahun 2002. Selanjutnya, di tahun 2005, W. Waldenziak mendetailkan tentang karakteristik dari B-Subaljabar Normal yang dapat diasumsikan bawah struktur dari B-Aljabar memiliki kemiripan dari struktur yang dimiliki oleh suatu grup. Selanjutnya di tahun 2014, Joemar C. Endam dan Jocelyn P. Vilela mendefinisikan kondisi himpunan yang merupakan hasil kali dari B-Subaljabar dan juga membuktikan teorema Isomorfisma kedua untuk B-Aljabar yang dikenal dengan teorema Diamond. Tulisan ini membahas mengenai sifat tambahan dari Teorema Diamond untuk B-AljabarA B S T R A C TThe concept of B-algebra was introduced by J. Neggers and HSKim in 2002.Furthermore, in 2005, W. Waldenziak detailed the characteristics of B-NormalSubalgebra which can be assumed that the structure of B-Algebra has similarities tothe structure owned by a group and in 2014, Joemar C. Endam and Jocelyn P. Vilelanot only defined set conditions which are the product of B-Subalgebra but also provethe second Isomorphism theorem for B-Algebra which is known as the Diamondtheorem.This paper discusses about the additional nature of the Diamond Theoremfor B-Algebra.

Abstract

Analisis statistika multivariat yang pada akhirnya menghasilkan sejumlah gerombol. Pengelompokan dilakukan pada objek/pengamatan (baris) dalam data yang memiliki kemiripan sangat besar dengan objek/pengamatan lainnya dalam satu gerombol. Kemiripan tersebut diukur menggunakan jarak euclidean. Analisis gerombol terbagi menjadi dua yaitu hierarki dan non-hierarki. Penelitian ini menerapkan analisis gerombol non-hierarki yaitu metode k-medoid untuk menggerombolkan kabupaten/kota beserta empat sektornya yaitu transportasi, industri/agro industri, pemukiman, perkantoran/komersial di Provinsi Sulawesi Selatan berdasarkan indikator penyusun nilai Indeks Kualitas Udara (IKU) tahun 2019 dan 2020. IKU ditetapkan sebagai salah satu instrumen untuk mengukur tingkat pencemaran udara di suatu wilayah, baik secara nasional maupun di Provinsi dan Kabupaten/Kota. IKU dikategorikan berdasarkan enam status Indeks Kualitas Lingkungan Hidup (IKLH). Untuk mendapatkan hasil gerombol dari metode k-medoid dan CLARA maka dilakukan penggerombolan berdasarkan perhitungan nilai IKU yaitu k = 6. Peneliti menggunakan confusion matrix untuk membandingkan hasil gerombol berdasar hasil gerombol metode k-medoid dan CLARA.. Dari penelitian yang dilakukan diperoleh hasil algoritma k-medoid untuk data 2019 maupun 2020 memiliki presentase Accuracy, Precision dan Recall lebih tinggi dibanding metode CLARA. Hasil tersebut membuktikan bahwa metode k-medoid mempunyai performa lebih baik bila dibandingkan dengan CLARA, karena mempunyai tinngkat akurasi dan recall lebih tinggi bila dibandingkan dengan CLARA. Itu disebabkan karena CLARA tergantung pada pemilihan dan ukuran sampel.

Abstract

Cluster analysis serves to group objects with high similarity of characteristics in one cluster while objects with dissimilarity of characteristics are in different clusters. Cluster analysis is divided into two, namely hierarchical and non-hierarchical. This study applies a non-hierarchical cluster analysis, namely the k-medoid method to group districts/cities and their four sectors, namely transportation, industrial/agroindustrial, residential, office/commercial in South Sulawesi Province based on indicators that make up the 2019 Air Quality Index (AQI) value and 2020. AQI are categorized based on six Environmental Quality Index (EQI) statuses. To get the best clusters from the k-medoid process, each cluster needs to be evaluated using the silhouette coefficient value. The results of this study indicate that k = 2 clusters from the k-medoid method are the best cluster initiations with the best silhouette coefficient value of 0.56. The results of the analysis of the cluster results show that with the use of 2 clusters, for 2019 passive sampler data, cluster 1 is included in the very good EQI category with a AQI value of 84.14 and cluster 2 is in the less EQI category with an AQI value of 60.04. For the 2020 passive sampler data, cluster 1 is included in the good EQI category with a AQI value of 80.68 and cluster 2 is in the less EQI category with a AQI value of 61.53.

Abstract

The beach is a region that is often used for various human activities, however often these utilization efforts cause beach problems so that the shoreline changes. One way that can be used to determine changes in shoreline is to make a mathematical model. The shoreline change model shaped of partial differential equation can be solved analytically by using the Elzaki transform method. The Elzaki transform method is a form of integral transform obtained from the Fourier integral so that the Elzaki transform and its basic properties are obtained. Shoreline change in this research were affected by groyne. Solution of shoreline change model using Elzaki transform method is carried by applying the Elzaki transform to the shoreline change model to obtain a new shoreline change model, then applying the boundary value, then applying the inverse of Elzaki transform so obtained a solution shoreline change model. Based on the research result, it was found that there was a similiarity between the graphic patterns generated from the solution of shoreline change model using Elzaki transform method and the solution of shoreline change model using numerical method.
