Abstract

Transaction data in the printing industry provides valuable insights into concurrently favored products by customers within a specific timeframe. Java Printing Batujajar has recorded printing transactions over the past 2 years. However, the lack of data management has led to disorganized raw material inventory, resulting in many unprocessed transaction records. The collected data consists of 704 printing transaction records from 2021 to 2022. Consequently, a solution is needed to identify patterns within this transaction data. This research aims to employ the association method with FP-Growth algorithm using the RapidMiner software. The research findings reveal an association between two products: "Buku Yasin L 208hl" (Complete/using elbow and tassel ribbon, 208 pages) and "Buku Yasin L 224hl" (Complete/using elbow and tassel ribbon, 224 pages). Both products exhibit the highest support value, accounting for 11.5% of total transactions, indicating their frequent simultaneous purchases. Moreover, the confidence value for the association between these two products reaches 100%, implying that if a customer purchases "Buku Yasin L 208hl," they will certainly buy "Buku Yasin L 224hl" as well. The test results indicate that by adjusting experimental parameters, higher support and confidence values are achieved compared to using default parameters. This signifies that experimental testing is more effective in discovering product associations and providing valuable information for optimizing the arrangement and storage of related raw materials.

Abstract

Program Keluarga Harapan (PKH) merupakan program pemberian bantuan sosial bersyarat kepada keluarga miskin yang ditujukan kepada keluarga penerima manfaat PKH. Melalui PKH, keluarga miskin didorong untuk memiliki akses dan memanfaatkan pelayanan sosial dasar di bidang kesehatan, pendidikan, pangan dan gizi, perawatan, serta pendampingan. Pada kelurahan Cibabat dan kelurahan Cipageran kecamatan Cimahi Utara terdapat 387 data penerima bantuan PKH pada tahun 2022. Namun belum adanya pengolahan data penerima bantuan PKH tersebut sehingga dalam melakukan pendampingan penerima bantuan PKH belum mendapatkan penglompokan yang sesuai dengan riwayat pendidikan. Berdasarkan latar belakang masalah yang telah dijabarkan, penulis tertarik untuk melakukan Clustering menggunakan Algoritma K-means pada data penerima bantuan PKH. Berdasarkan pengujian metode elbow pada algoritma k-means didapat nilai k yang optimal adalah k=3. Pengelompokan dataset yang digunakan menjadi 3 kelompok cluster, diantranya cluster_0 sebanyak 257 data, cluster_1 sebanyak 75 data, dan cluster_2 sebanyak 55 data. Pada cluster_0 di dominasi oleh peserta lulusan SD sebanyak 173 data, untuk cluster_1 di dominasi oleh peserta tidak sekolah sebanyak 40 data, dan untuk cluster_2 di dominasi peserta tidak sekolah sebanyak 48 data. Pada cluster tersebut didapatkan nilai performa berdasarkan rata-rata avg. within centroid distance_cluster_0 adalah 6.720, avg. within centroid distance_cluster_1 adalah 14.373, avg. within centroid distance_cluster_2 adalah 8.496 dan Davies Bouildin Index adalah 0.816. Hasil penelitian ini diharapkan menjadi acuan bagi pengurus sekretariat PPKH dalam melaksanakan pendampingan masyarakat penerima Program Keluarga Harapan.

Abstract

The problem is that the material using the "Heading" feature on the word processor application for automatic content list creation has not been submitted.  Another problem based on the observations is that the students are still not used to typing with ten fingers so it takes a long time when practicing computers.  The method used in the implementation of training activities is to display material continued with practicum. The "Heading" feature complements the material already presented by the teacher of the TIK subject, where the material has not been presented in front of the class.  As a result of ten-finger drawing training, there was an improvement in the students' ability to type although not significantly. The training material is very relevant to the curriculum used by Madrasah Aliyah Miftahussaadah and complement the materials already learned in the learning process by the teacher of the TIK subject. The participants were very enthusiastic during the training, it is proved with the participant's activity during the receipt of the training material.  For the team especially the students give a positive impact to sharpen the softskill skills of the students before plunging into the world of work and industry as well as to society.
