Abstract

Purpose: Efficient freshwater management is critical in cargo ship operations, yet current practices often involve fixed refilling strategies that ignore price differences across ports and fail to predict actual consumption accurately. These inefficiencies lead to unnecessary operational costs. To address this, the study introduces a combined approach using XGBoost for predict freshwater usage and Particle Swarm Optimization (PSO) to minimize refilling costs through optimal port selection. Methods: Freshwater demand was predicted using an XGBoost regression model trained on real operational data from 2024, which included historical voyage distances and freshwater consumption records from cargo ships. Based on these predictions, Particle Swarm Optimization (PSO) was applied to identify cost-efficient refilling locations along each ship’s route, minimizing total water procurement cost while satisfying operational constraints. The proposed framework was validated through simulated voyage scenarios to evaluate its impact on cost efficiency and planning effectiveness. Result: The integration of XGBoost and PSO effectively optimized freshwater refilling strategies, achieving a relative prediction error of 9.48% in freshwater consumption prediction and cost savings from 9 to 40% from across 3 ships sample through strategic port selection based on consumption patterns and price variability. Novelty: Unlike prior works focused on fuel or generic logistics optimization, aim of this study is to combine XGBoost and PSO for optimizing freshwater refilling on cargo ship voyages using actual operational data. The results demonstrate practical, scalable improvements in cost efficiency, making a novel contribution to maritime resource planning.

Abstract

Single Sign-On atau SSO merupakan metode autentikasi tunggal dimana pengguna cukup melakukan autentikasi sekali untuk mengakses beberapa sistem atau aplikasi yang terdaftar. Proses autentikasi yang digunakan pada SSO menggunakan metode autentikasi klasik. Penyerang dapat mencuri data pengguna pada proses komunikasi autentikasi antara pengguna dan server, serangan ini disebut dengan Man In The Middle Attack (MITM). Nonce adalah tindakan untuk melindungi informasi pribadi dan rahasia serta nilai unik yang tidak akan diulang. Pada makalah ini mengusulkan metode autentikasi pada SSO dengan kombinasi algoritma timestamp nonce dan nilai salt. Kombinasi dari kedua algoritma tersebut akan menghasilkan sebuah nilai acak yang bersifat unik. Nilai unik yang dihasilkan tersebut akan digunakan untuk mengenkripsi nama pengguna dan kata sandi pada tahap autentikasi. Sehingga diharapkan dengan metode tersebut dapat mengamankan data pengguna dari pencurian data dan serangan MITM. Penerapan kombinasi algoritma Timestamp Nonce dan nilai salt dapat dijadikan salah satu alternatif pengamanan autentikasi pada sistem SSO. Selain itu, peneliti juga melakukan uji coba serangan MITM dengan melakukan pembacaan setiap paket data yang bertujuan mendapatkan nama pengguna dan kata sandi. Hasilnya adalah variabel nama pengguna dan kata sandi bersifat unik dan tidak bisa di dekripsi.

Abstract

Air mineral sangat penting bagi kesehatan manusia karena berperan dalam hidrasi tubuh, menjaga keseimbangan cairan, dan mendukung fungsi organ serta sistem tubuh. Untuk memenuhi kebutuhan sehari-hari, distribusi dari depo air ke pelanggan harus mempertimbangkan rute tercepat agar biaya pengiriman efisien. Mencari rute terpendek dengan alokasi depo terbaik dengan tetap mempertimbangkan keterbatasan kapasitas masing-masing depo dan kendaraan merupakan tujuan dari penelitian ini. Algoritma Hill Climbing merupakan metode yang efektif untuk menentukan rute terdekat antar titik pengiriman. Selain itu, algoritma A* dapat digunakan untuk mencari rute optimal dengan menggunakan informasi tambahan (heuristik) yang mengarahkan pencarian ke jalur yang paling efisien. Berdasarkan hasil penelitian, 450,41 merupakan rute terjauh dengan menggunakan moda transportasi penjemputan dengan satu depo. Sedangkan untuk moda transportasi penjemputan dengan dua depo, jalur terpendek adalah 257,62; sedangkan untuk menggunakan sepeda motor atau kereta api, jalur terpendek adalah 271,75.

Abstract

Agriculture is the primary sector in Indonesia for meeting people's daily food demands. One of the agricultural commodities that replace rice is potatoes. Potato growth needs to be protected from weeds that compete for nutrients. Spraying using pesticides can cause environmental pollution, affecting cultivated plants. Currently, agricultural technology is being developed using an Artificial Intelligence (AI) approach to classifying crops. The classification process using AI depends on the number of datasets obtained. The number of datasets obtained in this research is not too large, so it requires a particular approach regarding the AI method used. This research aims to use a combination of feature extraction methods with local and deep feature approaches with supervised machine learning to classify of small datasets. The local feature method used in this research is Local Binary Pattern (LBP) and Histogram of Oriented Gradients (HOG), while the deep feature method used is MobileNet and MobileNetV2. The famous Support Vector Machine (SVM) uses the classification method to separate two data classes. The experimental results showed that the local feature HOG method was the fastest in the training process. However, the most accurate result was using the MobileNetV2 deep feature method with an accuracy of 98%. Deep features produced the best accuracy because the feature extraction process went through many neural network layers. This research can provide insight on how to analyze a small number of datasets by combining several strategies
