Abstract

Program Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk mendukung para pembudidaya ikan lele dalam memilih bibit unggul dengan memanfaatkan aplikasi berbasis teknologi. Kendala utama yang sering dihadapi adalah minimnya pemahaman dalam menentukan kualitas bibit yang baik, sehingga berpengaruh terhadap rendahnya tingkat keberhasilan dalam budidaya. Kegiatan ini mencakup pengembangan serta pelatihan penggunaan aplikasi yang dirancang untuk membantu proses seleksi bibit lele berdasarkan sejumlah kriteria, seperti ukuran, kesehatan, dan tingkat kelincahan ikan. Pelaksanaan program dilakukan dalam beberapa tahapan, mulai dari perancangan aplikasi, pengujian, hingga sosialisasi dan pelatihan kepada pembudidaya. Berdasarkan hasil pelaksanaan, aplikasi yang dikembangkan terbukti mampu meningkatkan efisiensi dalam pemilihan bibit serta memperluas wawasan peserta mengenai karakteristik bibit lele berkualitas. Dengan demikian, program ini diharapkan dapat memberikan kontribusi positif terhadap peningkatan produktivitas dan keberlanjutan usaha budidaya lele di kalangan masyarakat.

Abstract

Object shape recognition in digital images is a crucial aspect of image processing and computer vision. This study implements the thresholding method as a segmentation technique to identify the shape of salak fruit (snake fruit) in digital images. The thresholding technique is applied to separate the main object (salak fruit) from the background based on pixel intensity differences. The process involves image acquisition, grayscale conversion, and the application of thresholding to produce a binary image. Morphological analysis is then conducted to extract shape features from the segmented object. The results indicate that the thresholding method is effective in recognizing the shape of salak fruit, achieving good accuracy under well-contrasted lighting and background conditions. This implementation can serve as a foundation for automated fruit classification or identification systems based on digital image processing.

Abstract

This study discusses multivariate data analysis for customer segmentation using Principal Component Analysis (PCA) combined with the K-Means clustering method. The problem faced is the high dimension of customer data which makes it difficult to segment and make targeted marketing decisions. The solution offered is the implementation of PCA to reduce the data dimension without losing important information, then followed by K-Means to segment customers based on demographic attributes and shopping behavior. Using a dataset of 200 customers, three customer clusters with different characteristics in terms of age, annual revenue, and shopping score were found. The results of the PCA show that the first two main components are able to explain more than 78% of the data variation, making it easier to visualize and interpret the cluster. These findings provide the basis for a more targeted marketing strategy according to customer segments. In conclusion, the combination of PCA and K-Means is effective in simplifying complex data and resulting in meaningful customer segmentation.

Abstract

Indonesia is the third-largest country in the world with rice production reaching 83,037,000 and became the highest production in southeast Asia spread in several provinces in Indonesia The problem found that such product has not been able to cover the needs of Indonesian people with a very high population so that in the research conducted information excavation to generate potential to the pile of data that has been described and analyzed by BPS with clustering topics. Clustering will help related parties, especially the ministry of agriculture, in determining land development priorities and can minimize the shortage of rice production nationally. Grouping process by involving the K-means algorithm to group rice production with a combination of the elbow method as part of determining the number of clusters that will be recommended with attributes supporting the area of harvest, productivity, and production. Method of researching with data cleaning activities, data integration, data transformation, and application of K-means with a combination of elbow and pattern evaluation. The results achieved based on the work description with a combination of K-Means and elbow provide cluster recommendations that are the best choice or the most optimal is iteration 2 which is the lowest rice production group with a total of 22 provinces, rice production with a medium category of 9 and production with the highest category with 3 regions

Abstract

Inventory stock management is an important aspect in the laundry business to ensure smooth operations and minimize costs. Laundry Detergent shortages or overstocks can cause service disruptions and unnecessary additional costs. Therefore, a method is needed that can help predict stock needs accurately, one of which is the linear regression method. The data used includes historical data on detergent use and other factors that influence demand over several time periods. Through linear regression analysis, a predictive model can be built to estimate detergent needs in the future, so that stocks can be managed more efficiently. Research Method, namely the survey research method, is a research method carried out using surveys or direct data collection from Laundry Luch. The method/algorithm used to analyze the data is the linear regression method. The aim of this research is to apply the linear regression method in detergent inventory stock and to carry out analysis using the linear regression method in detergent inventory stock. The research results from the data that have been collected show that the predicted stock of detergent supplies for Laundry Luch in January 2025, with an estimated total usage of 111 boxes of detergent and a target usage of 95 boxes of detergent, is 129 boxes of detergent. The research conclusion is that the linear regression method provides real benefits in supporting data-based decision making.

Abstract

WhatsApp merupakan salah satu aplikasi pesan instan yang banyak di gunakan saat ini. WhatsApp memungkinkan pengguna membuat grup. Sering pesan pada grup tidak terbaca dan terabaikan oleh anggota grup. Perlu dilakukan analisa waktu yang tepat sebuah pesan direspon anggota grup dengan cepat sehingga informasi dapat disampaikan dengan baik pada semua anggota. Penelitian ini melakukan explorasi WhatSapp Group “Gurauan kita STMIK Amik” untuk menentukan waktu terbaik menyampaikan pesan dengan metode timeline serta menganalisis anggota yg berjumlah 32 orang, emoji dan sentimen. Pada Analisis sentimen dari 1095 total pesan, sentimen positif 35.53% dan sentimen negatif 64.47%. Respon emoji dari anggota sebanyak 46% menggunakan pesan emoji diatas 50% dan 34% anggota menggunakan emoji dibawah 50% sedangkan 18 % anggota tidak pernah menggunakan emoji. Dalam penelitian ini dari proses timeline dapat disimpulkan waktu terbaik untuk mengirimkan pesan pada hari selasa dan jum’at pada jam 10, 13 sampai 15 siang dan jam 20 pada malam hari.

Abstract

Accurate crop yield prediction is essential to support agricultural planning, food supply stability, and decision-making in modern precision agriculture. Agricultural production is influenced by many complex and nonlinear factors such as rainfall, temperature, humidity, soil conditions, and fertilizer usage. Traditional statistical methods often face limitations in handling high-dimensional and nonlinear agricultural datasets. Therefore, this study proposes a crop yield prediction model using Artificial Neural Network (ANN) combined with Principal Component Analysis (PCA) for dimensionality reduction. PCA is applied in the preprocessing stage to reduce redundant and correlated input variables while preserving the most important data variance. The reduced dataset is then used to train the ANN model to predict crop yield values. The model is implemented using Python with libraries including NumPy, Pandas, Scikit-learn, and TensorFlow/Keras. The dataset used in this research consists of 1000 agricultural records covering three crop commodities, namely maize, barley, and rice. Model performance is evaluated using visualization techniques including histogram error, histogram predicted, PCA explained variance, predicted vs actual plot, residual plot, and training history graph. Experimental results show that the PCA-ANN model produces accurate and stable prediction results with low prediction error and strong agreement between predicted and actual values. The integration of PCA and ANN improves prediction performance, reduces computational complexity, and minimizes overfitting risk. This research demonstrates that the PCA-ANN approach is effective for crop yield prediction and can support data-driven agricultural decision-making.
