Abstract

Pinjaman online (pinjol) banyak menuai pro dan kontra karena aksesnya yang mudah dan iklannya tersebar di media sosial. Penyelenggara pinjaman daring juga seringkali menggunakan metode penagihan yang mengganggu, memberlakukan bunga yang tinggi, dan menetapkan jangka waktu pembayaran yang pendek, terutama pada pinjaman daring ilegal. Karenanya, penelitian ini melakukan analisis sentimen pada lima aplikasi pinjol, yaitu Kredivo, Easycash, Rupiah Cepat, Kredit Pintar, dan Ada Pundi. Data ulasan aplikasi diambil dari Google Play Store menggunakan teknik scraping. Kemudian, pelabelan sentimen dilakukan secara otomatis menggunakan kamus sentimen Bahasa Indonesia (Inset). Hasil pelabelan menunjukkan bahwa semua aplikasi pinjol mayoritas memiliki sentimen negatif. Kredivo menjadi aplikasi dengan jumlah sentimen positif terbanyak (46%), sementara itu Easycash memiliki sentimen negatif terbanyak (65%). Data yang di labeli kemudian digunakan untuk pemodelan klasifikasi dengan algoritma Support Vector Machine (SVM). Hasil evaluasi menghasilkan algoritma SVM mempunyai kinerja yang cukup baik dengan rata-rata akurasi sebesar 72%, presisi 76%, dan recall 85%. Namun secara khusus, SVM sangat baik melakukan klasifikasi sentimen pada aplikasi Kredit Pintar dengan akurasi sebesar 83%. Analisis visualisasi menggunakan word cloud juga dilakukan untuk memahami konteks ulasan pengguna aplikasi pinjol. Hasil pengamatan menunjukkan bahwa pengguna hampir selalu membahas tentang limit pinjaman disetiap sentimen pada kelima aplikasi.

Abstract

Motor vehicle production in Indonesia increases every year along with increasing demand for fuel as a raw material. Generally, gas stations carry out the process of ordering fuel from Dempo on an irregular basis, the frequency of orders does not have a certain time, orders depend on sales transactions and the amount of fuel inventory available depends on the fuel in storage. Regarding prediction and control of fuel supplies, the risk at gas stations is that the volume of fuel received is different from that ordered. It is suspected that tank trucks carrying fuel during delivery from the depot to gas stations tend to experience evaporation in the tank (loses), so that the fuel quantity decreases. Requests for fuel filling are only based on monitoring without any special calculations resulting in stock being maintained and not covering consumer demand. This research is to analyze the Artificial Neural Network algorithm in predicting fuel, and determine inventory control using Economic Order Quantity. The research was conducted using data from November 2020 - October 2023. The data was processed using the ANN algorithm using Google Colab, and continued with EOQ using Microsoft Excel. The ANN parameters are 1 hidden layer with 100 units, Adam optimizer, learning rate 0.001, batch size 8 and epoch 200. Pertalite ANN test results are MSE 248852593.81 and MAE 12749.45, while Pertamax Turbo MSE 803842.94 and MAE 672, 74 provides predictions for November and December of 11,1436.82 L and 11,1960.83 L and Pertamax Turbo of 3,782.46 L and 3,660.70 L. Furthermore, in 2023 the fuel EOQ of Pertalite and Pertamax Turbo will be 8,445 L and 5,261 L, Safety Stock 3,516 L and 1,064 L, Maximum Inventory 6,042 L and 5,153 L, Re order point 2,403 L and 108 L, Order frequency 149 times and 6 times with Total Inventory Cost Rp. 178,830,302 and Rp. 7,700,459.

Abstract

Indonesia faces a serious challenge related to stunting, with rates reaching 21% in 2024, although this represents a decrease from 24% in 2021. In response, the government has launched various programs to address this issue, including nutrition education, health check-ups for pregnant women, and supplementary food provisions. Amid these efforts, the proposed free lunch program aims to improve nutritional quality for children and pregnant women. However, this program has sparked controversy over the required budget, estimated at IDR 450 trillion, which could impact the national budget balance and lead to inflation.This study analyzes public sentiment toward the free lunch program using the Naïve Bayes Classifier (NBC) and Support Vector Machine (SVM) algorithms. An analysis of 1,028 tweets revealed that negative sentiment predominates at 44.84%, followed by positive sentiment (32.39%) and neutral sentiment (22.76%). SVM outperformed NBC with an accuracy of 75.39%, compared to NBC's 68.97%. The findings provide important insights into public perceptions of the program and highlight the need for further research to improve sentiment analysis methodologies.

Abstract

Teknologi informasi telah banyak diterapkan di berbagai perusahaan, salah satunya PT XYZ yang telah menerapkan sistem informasi penjualan atau BEI sebagai otomatisasi proses bisnis perusahaan. Namun pada praktiknya manajemen risiko sistem informasi BEI belum diterapkan dengan baik, masih terdapat kendala dan insiden pengelolaan. Penelitian ini bertujuan untuk menganalisis manajemen risiko sistem informasi ISX dengan menggunakan framework FMEA (Failure Mode Effects and Analysis). FMEA dapat mengidentifikasi risiko berdasarkan tingkat keparahan suatu kejadian, seberapa sering kejadian tersebut terjadi, dan seberapa tinggi tingkat deteksinya. Dari variabel-variabel tersebut akan dihasilkan Risk Priority Number (RPN) yang dapat menentukan prioritas risiko atau permasalahan yang paling kritis. Hasil penelitian ini menunjukkan bahwa sistem ISX mempunyai 2 risiko dengan tingkat sangat tinggi, 1 risiko dengan tingkat tinggi, 1 risiko dengan tingkat menengah, 21 risiko dengan tingkat rendah, dan 5 risiko dengan tingkat sangat rendah. Risiko yang berada pada tingkat yang sangat tinggi dan tinggi merupakan risiko yang diprioritaskan dan perlu mendapatkan tindakan dan pengendalian risiko.

Abstract

Oil palm is one of the important plantation crops and a leading commodity in Indonesia. PT. XYZ is a company engaged in receiving Fresh Fruit Bunches (FFB) to be processed into Crude Palm Oil (CPO) and Palm Kernel (PK). So far, the company has conducted statistical analysis with a correction value of 5% - 12% on the production results each month in targeting production results. However, this method is still lacking, because it uses manual calculations and considers estimates from personal experience. Therefore, this research proposes a data mining technique with Support Vector Regression (SVR) and Recurrent Neural Network (RNN) algorithms to predict production output precisely. In this study, testing was carried out on SVR hyperparameters, namely Kernel, C, Gamma, and Epsilon. While in RNN, testing is carried out on the optimizer, and the learning rate. In addition, the window size is also determined through a series of experiments, namely 3, 5, and 7. The comparison results show that the RNN model outperforms SVR with an RMSE value of 0.0928, MAPE of 14.32%, and R2 of 0.6164. The RNN model was then implemented to predict the next 3-month period. The prediction results show that there will be a significant increase in production in the first month, then a slight decrease in the second month, and an increase again in the third month.

Abstract

Bazmart Pelalawan is a part of the National Zakat Agency (BAZNAS) program in Pelalawan Regency, which has implemented strategies to retain customers. However, these strategies have not yet succeeded in fully understanding customer characteristics, resulting in a decline in customer trust and their willingness to shop again. Additionally, Bazmart lacks proper guidelines for offering products that meet customer needs. This research aims to enhance product recommendations by integrating LRFM analysis into data mining techniques. The parameters considered include customer LRFM values, customer segmentation, and products frequently purchased together over a year of transaction data. Fuzzy C-Means and FP-Growth algorithms were used for segmentation and association analysis. The segmentation results identified two customer clusters with a Davies-Bouldin Index (DBI) value of 0.628, indicating good cluster quality. In the association analysis, a minimum support (minsup) of 30% and a minimum confidence (mincof) of 70% were used, resulting in 8 rules for cluster 1 and 17 rules for cluster 2. From the two association pattern results, the highest rules were obtained, namely in Drinks and Snacks and Bread with a support value of 0.426 and a confidence value of 0.926 resulting in a value of 0.394. These rules provide insights that Bazmart Pelalawan can use to develop more effective and targeted direct marketing strategies for each customer cluster. Thus, this research is expected to help Bazmart Pelalawan better understand customer characteristics and improve customer loyalty through more targeted product recommendations.

Abstract

PT X is a retail company engaged in printing. The company has not differentiated between information about profitable and unprofitable customers for the company. Transaction data is only used as profit and loss information so they do not know the characteristics of the customers they have. In addition, the lack of extensive services in the merchandise category is one of the reasons the company's revenue has not reached the predetermined target. Currently, the company has opened additional services in the merchandise field. This research aims to identify customer segmentation as well as analyze the characteristics and provide a strategy proposal that will be submitted to PT. X. Customer loyalty and characteristics have a significant impact on a company. To identify customers who show loyalty to the company, the Fuzzy C-Means algorithm is used to perform clustering, using the Davies Bouldin Index (DBI) to evaluate the clustering results. The model used is in accordance with the principles of Length, Recency, Frequency, Monetary and Diversity (LRFMD) to categorize purchasing patterns. By analyzing LRFMD variables, it is possible to identify customers who are loyal to the company and those who are not. This research produces 6 clusters with the best cluster or supestar customer in cluster 6, the second best value customer or golden customer is cluster 2, the average value customer or typical customer is cluster 4 and 5 and the lowest cluster or dormant customer is in cluster 3.
