Pemanfaatan k-Means Clustering dan Analytic Hierarchy Process terhadap Penilaian Prestasi Kerja Pegawai
As a government agency related to education and culture, the Department of Education and Culture of Bengkayang Regency needs qualified employees in their performance. Clustering can be used to determine whether the employee is performing well, moderately, or poorly. The clustering method used in this study is the k-Means method. The research wasconducted by studying and understanding the k-Means method and knowing employee performance data at the Education and Culture Office of Bengkayang Regency. The results of calculations using the k-Means method and the Analytic Hierarchy Process (AHP) method are as many as six employees have good performance (where two of them got the highest score in the AHP calculation), nine employees have moderate performance, and five employees have poor performance. These results can be used as a benchmark for employees in the cluster either to be promoted or rank, while employees in the cluster less are able to begiven employee performance training, in order to be better in the future. With this, employees can become more competitive and superior in the face of increasingly rapid developments.

Serverless Named Entity Recognition untuk Teks Instruksional Pertanian Kota
The evolution of document documentation, classification, and information retrieval includes named entity recognition (NER). The implementation of NER in the agricultural domain, in particular instructional texts or transcriptions of tutorial videos, will make it easier for the general public to understand the specific concepts and terms of urban agricultural activities such as crop production processes and procedures, agricultural methods and tools, harvest cycles, and handling plant pests or diseases. Spacy is an NLP tool, has two methods of developing NER models, namely with Toc2Vec and Transformer. Both methods have advantages and disadvantages, namely different sizes, performance and prediction speeds according to needs. The NER model can be implemented into a Serverless application, using the Functional as Services (FaaS) and Backend as Services (BaaS) approaches. For the subtopic of cultivating fruit crops in agricultural instructional literature, three NER models have been built in this study. First, the IndoBERT-based model, the Toc2Vec-based model with efficiency optimization, and the Toc2Vec-based model with accuracy optimization. The most efficient toc2vec model, with a f1-score of 0.71, is followed by the effective toc2vec model, with a f1-score of 0.60. The COUNT, PERIOD, and VERIETAS entities are consistently predicted incorrectly by the Toc2Vec model, which is unable to forecast numeric entities well. In addition, the Toc2Vec Model's better efficiency optimization directly relates the size of the model to the speed of word prediction per second, and the model is simple to integrate into a FaaS- and BaaS-based Serverless. The capabilities of Serverless M have been successfully tested using the black box method.Named Entity Recognition(NER) merupakan bagian dari pengembangan perangkuman dokumen, klasifikasi dan pencarian informasi. Implementasi NER pada domain pertanian, khususnya teks instruksional atau transkripsi video tutorial, akan memudahkan masyarakat umum memahami konsep dan istilah khusus dari kegiatan pertanian kota seperti proses dan prosedur produksi tanaman, metode dan alat pertanian, siklus panen, dan penanganan hama atau penyakit tanaman. Spacy merupakan alat bantu NLP, memiliki dua metode pengembangan model NER, yaitu dengan Toc2Vec dan Transformer. Kedua metode memiliki kelebihan dan kekurangan, yaitu ukuran, performansi dan kecepatan prediksi yang berbeda beda sesuai kebutuhan. Model NER dapat diimplementasikan menjadi aplikasi Serverless, dengan menggunakan pendekatan Fungsional as Services (FaaS) dan Backend as Services (BaaS). Pada penelitian ini telah dikembangkan tiga model NER untuk data teks instruksional pertanian sub topik budidaya tanaman buah. Model berbasis Toc2Vec dengan optimasi efisiensi, Model Toc2Vec dengan optimasi akurasi dan Model berbasis IndoBERT. Model berbasis Transformer memiliki nilai f1-score terbaik sebesar 0.71 disusul Model Toc2Vec Efisiensi sebesar 0.60 dan Model Toc2Vec Efektif dan 0.57. Model Toc2Vec tidak dapat memprediksi entitas numerik dengan baik, Prediksi entitas COUNT, PERIOD dan VERIETAS selalu tertukar. Selain itu Ukuran model berbanding lurus dengan kecepatan prediksi kata per detik, dalam hal ini Model Toc2Vec optimasi efisiensi unggul, model tersebut mudah diimplementasikan menjadi Serverless berbasis FaaS dan BaaS. Fungsionalitas dari Serverless ML telah berhasil diuji menggunakan metode Blackbox

Segmentasi dan Pembentukan Model Regresi Nasabah Berbasis Analisis Recency, Frequency dan Monetary
During this pandemic, the number of customers of a securities company has increased quite high. This requires securities companies to conduct analysis related to security customer data against transaction data so that the company can find out the segmentation of registered customers and also so that companies can predict the transaction patterns of customers in the company. In processing transaction data, the RFM (Recency, Frequency, Monetary) model can be used as a way to group customers according to their business values. After doing the modeling using RFM, the data is clustered using the K-Means algorithm to find out the segmentation in the RFM model in each group. The RFM model that has been clustered will produce segments based on the RFM group. In this data, a linear regression analysis process is carried out where each group and segment is analyzed and predicted related to variables such as recency, monetary and frequency. The results of data grouping, customer segmentation and also predictions with linear regression can be one of the company's references to make a business decision. From the linear regression process carried out on the RFM attributes, a prediction of the monetary value of the existing recency value is generated and the monetary value of the frequency can also be known with a fairly good error rate.Di masa pandemi ini, peningkatan jumlah nasabah suatu perusahaan sekuritas meningkat cukup tinggi. Hal tersebut mengharuskan perusahaan sekuritas untuk melakukan analisis terkait data nasabah sekuritas terhadap data transaksi agar perusahaan tersebut dapat mengetahui segmentasi dari nasabah yang sudah terdaftar dan juga agar perusahaan dapat memprediksi terkait pola transaksi dari nasabah yang ada di perusahaan tersebut. Dalam melakukan pengolahan data transaksi dapat menggunakan model RFM (Recency, Frequency, Monetary) sebagai cara untuk pengelompokan nasabah sesuai dengan nilai bisnis yang dimiliki. Setelah melakukan pemodelan dengan menggunakan RFM , data yang tersebut dilakukan Clustering dengan menggunakan algoritma K-Means untuk mengetahui segmentasi yang ada dalam model RFM dalam setiap kelompoknya. Model RFM yang sudah dilakukan clustering akan menghasilkan suatu segmen-segmen berdasarkan kelompok RFM. Pada data tersebut dilakukan proses analisis regresi linear dimana pada setiap kelompok dan segmen dianalisis dan diprediksi terkait variabel-variabel seperti recency, monetary dan frequency. Hasil dari pengelompokan data, segmentasi pelanggan dan juga prediksi dengan regresi linear ini dapat menjadi salah satu acuan perusahaan untuk membuat suatu keputusan bisnis. Dari proses regresi linier yang dilakukan atas atribut-atribut RFM, dihasilkan suatu prediksi nilai moneter dari nilai recency yang sudah ada dan juga dapat diketahui nilai moneter dari frequency dengan tingkat error yang cukup baik
