Abstract

Bengkulu Province ranks second in the category of the highest percentage of poor people in the Sumatra region, at 14.62% in March 2022, and sixth in Indonesia, which is undoubtedly one of the fundamental problems that requires mutual attention. The phenomenon of high poverty in Bengkulu Province is inseparable from the lives of people whose main livelihood is in the agricultural sector, especially tenant farmers. Therefore, in this study, the Copula and Gaussian Copula Marginal Regression (GCMR) methods are applied to determine how the agricultural sector affects poverty in Bengkulu Province using secondary data obtained from the Bengkulu Provincial Statistics Agency (Susenas 2022). The results show that the Copula model can identify various types of dependency between the number of poor households in each district/city in Bengkulu Province in 2022 and each of the variables, namely the Number of Agricultural Business Households , the Growth Rate of the Agricultural Sector , the Human Development Index , and the Open Unemployment Rate ( ) by considering the different characteristics of dependency such as top-tail, bottom-tail, or negative dependency. Meanwhile, the GCMR model can provide the direction of influence of the independent variables on the dependent variable Y, where it can be seen that the variables , , and have a negative influence on the variable , whie the variable has a positive impact on the variable . Therefore, in general, it can be concluded that either positive or negative dependencies identified by the Copula model can influence the resulting GCMR model by providing more profound complexity regarding the relationship between the variables analyzed.

Abstract

Kredit rumah tangga di Provinsi Bengkulu berperan penting dalam mendukung kesejahteraan masyarakat, terutama dalam memenuhi kebutuhan dasar seperti perumahan, pendidikan, dan barang konsumsi. Namun tidak semua jenis pekerjaan utama memiliki kemampuan yang sama dalam memenuhi syarat pengajuan kredit. Dengan  permasalahan   tersebut  penelitian   ini   bertujuan  melihat  asosiasi jenis pekerjaan dan jenis kredit rumah tangga dengan menggunakan metode log linear 2 dimensi. Berdasarkan hasil pengujian asosiasi didapatkan hasil berupa terdapat asosiasi antara jenis pekerjaan dan kredit. Setelah melakukan pengujian dilakukan pemilihan model terbaik dengan menggunakan pengujian Goodness of fit (uji G). Berdasarkan hasil pengujian Goodness of fit (uji G) bahwa model dengan interaksi lebih baik dibandingkan model tanpa interaksi.

Abstract

The Growth of the e-commerce industry has resulted in a massive volume of transaction data, necessitating effective data analysis techniques to extract customer purchasing patterns. The Frequent Pattern Growth (FP-Growth) algorithm is one of the data mining methods that can be used to identify frequently occurring purchase patterns without explicitly generating candidate itemsets. This study aims to implement and evaluate the performance of the FP-Growth algorithm in analyzing e-commerce transaction data to identify recurring shopping patterns. The research methodology includes transaction data collection, data preprocessing, FP-Growth algorithm implementation, and result analysis. This study utilizes an e-commerce transaction dataset from an online retail store based in the United Kingdom, comprising 541,909 transaction records. The research findings indicate that the FP-Growth algorithm is efficient in identifying frequently occurring transaction patterns. Using a support threshold of 1% and a confidence level of 80%, 13 association rules were discovered, demonstrating relationships between frequently co-purchased products. Further analysis shows that these findings can be leveraged by e-commerce businesses to develop marketing strategies based on product recommendations. In conclusion, the FP-Growth algorithm is an effective approach for extracting purchasing patterns from large-scale e-commerce transaction data.
LITERASI STATISTIKA DESKRIPTIF BERBASIS WEB MENGGUNAKAN R-SHINY UNTUK SISWA SMA MUHAMMADIYAH 4 KOTA BENGKULU Sriliana, Idhia; Afandi, Nur; Dyah Pangesti, Riwi; Wijuniamurti, Susi; Fairuzindah, Athaya; M. Syarlan

Abstract

Tujuan dari kegiatan Pengabdian Kepada Masyarakat (PKM) ini adalah untuk meningkatkan literasi statistika deskriptif siswa SMA Muhammadiyah 4 Kota Bengkulu melalui pemanfaatan aplikasi berbasis web menggunakan R-Shiny. Literasi statistika deskriptif menjadi keterampilan penting dalam memahami, mengolah, dan menyajikan data secara sistematis. Tahapn-tahapan yang dilakukan antara lain perancangan, persiapan, implementasi, dan evaluasi, dengan produk utama berupa aplikasi Kalkulator Statistika berbasis R-Shiny, modul pembelajaran, implementation arrangement, dan poster edukatif. Evaluasi kegiatan dilakukan dengan pemberian pre-test dan post-test guna mengetahui peningkatan literasi siswa. Nilai rata-rata pre-test ke post-test siswa meningkat dari 46,66 menjadi 74,66 setelah pelatihan. Hal ini sejalan dengan hasil uji paired sample t-test yang menghasilkan nilai t-statistik sebesar 6,18 dengan p-value 0,00 (<0,05) yang berarti ada peningkatan signifikan antara nilai pre-test yang menggambarkan nilai sebelum pelatihan dengan nilai post test yang mencerminkan nilai sesudah pelatihan. Uji normalitas data dilakukan menggunakan statistik Kolmogorov-Smirnov dan Shapiro-Wilk yang menyimpulkan bahwa data memiliki sebaran normal (p>0,05). Dengan demikian, kegiatan literasi statistika deskriptif berbasis web menggunakan R-Shiny terbukti efektif dalam meningkatkan pemahaman konsep statistika deskriptif siswa serta berkontribusi dalam memperkuat integrasi teknologi informasi dalam pembelajaran dan menumbuhkan minat terhadap bidang statistika dan analisis data.
