Analisis Penentuan Rute Pengiriman Sparepart Dengan Metode Ant Colony Optimization (ACO) Di PT Threelog Kencana Mandiri Batam
Get PDFRoute distribution efficiency is a crucial aspect of logistics operations, particularly for companies engaged in spare part delivery. PT Threelog Kencana Mandiri, operating in Batam, faces delivery delays due to a suboptimal route determination system, resulting in long travel distances, high operational costs, and distribution delays. This study aims to optimize delivery routes by applying the Ant Colony Optimization (ACO) algorithm, a metaheuristic method inspired by the behavior of ants in finding the shortest path. The problem is modeled as a Vehicle Routing Problem (VRP) by considering delivery destinations, distance matrices,
and vehicle capacities. The ACO algorithm constructs routes based on pheromone intensity and heuristic visibility, followed by local and global updates to obtain
more optimal solutions. The research results show a significant reduction in total travel distance compared to the company’s current routes. This optimization has an
impact on fuel efficiency, reduced delivery times, and increased customer satisfaction. This study also demonstrates that the ACO algorithm can solve real
world routing problems with dynamic variables

segmentation identified groups of loyal and at-risk customers, providing a data
driven foundation for targeted marketing strategies and supporting strategic
decision-making within the context of small and medium-sized enterprises
PENGELOMPOKAN UMKM DI KABUPATEN MALANG DENGAN METODE ENSEMBLE ROBUST CLUSTERING USING LINKS (ROCK)
No full textMicro, Small, and Medium Enterprises (MSMEs) are the backbone of Indonesia’s economy, including in Malang Regency, which has strong growth potential in the food, beverage, and souvenir sectors. However, the mapping of MSME business characteristics which involve both numerical and categorical data has not been optimally implemented, making it difficult for local governments to design targeted development strategies. This study addresses the problem of accurately clustering MSMEs while considering the complexity of their business variables. The method used is Ensemble Robust Clustering using Links (ROCK), which combines the advantages of numerical data clustering using Agglomerative Hierarchical Clustering and categorical data clustering using ROCK, enabling the effective integration of both variable types. The analytical process includes preprocessing steps such as outlier handling, numerical variable standardization using Z-score, and categorical variable encoding using Label Encoding. The urgency of this research lies in the need for accurate MSME segmentation to support business digitalization and data-driven policymaking. The innovation of this study, compared to previous research, is the application of the ensemble ROCK method to MSME data with the addition of strategic variables such as the involvement of online motorcycle taxis (ojol) as an indicator of digital readiness an aspect that has not been widely explored. This research aims to produce an informative and valid MSME clustering model for Malang Regency, as well as the development of a web-based graphical user interface (GUI) for interactive visualization of the clustering results. These findings are expected to serve as a foundation for designing more targeted and adaptive MSME development policies in response to digital economic trends

Klasifikasi Kesegaran Ikan Bandeng Berdasarkan Citra Mata Menggunakan MobileNetV3-Small Dan SVM
No full textManual freshness assessment of milkfish is often subjective and inconsistent because it depends on individual experience. This study aims to develop a freshness classification model of milkfish based on fish eye images using a combination of MobileNetV3-Small as a feature extractor and Support Vector Machine (SVM) as a classification algorithm. The dataset used consists of 340 milkfish eye images with two categories, fresh and not fresh, obtained from primary data collection as well as online sources. An augmentation process was applied to expand the variety of training data, including rotation, horizontal and vertical flip, and brightness adjustment. The images were then processed through the MobileNetV3-Small architecture to produce a 576-dimensional feature vector, which became the input for the SVM model. Evaluation was conducted with various test scenarios such as variations in data proportion, kernel, and SVM parameters (C and gamma). The results showed that the combination of MobileNetV3-Small and SVM with RBF kernel, C=10, and gamma=0.01 gave the best performance with 99,02% accuracy. This model is then implemented in a web application using the Flask framework to facilitate real-time classification of fish freshness. This research shows that MobileNetV3-Small and SVM approaches are effective and efficient for visual classification of biological objects such as milkfish
KOMUNIKASI INTERPERSONAL ORANG TUA DAN REMAJA DALAM KEPUTUSAN PERNIKAHAN DINI DI KECAMATAN BLUTO KABUPATEN SUMENEP
No full textThis study aims to find out how interpersonal communication between parents and
adolescents is related to early marriage decisions in Bluto District, Sumenep
Regency. The phenomenon of early marriage is still widely found in the area with
backgrounds such as local culture and low education. Data was collected through
in-depth interviews with 8 informants, parents, and 8 adolescents who had or were
experiencing early marriage. The Theory of Communication Accommodation by
Howard Giles is used as a theoretical foundation, focusing on strategies of
convergence, divergence, and excessive accommodation. The results of the study
show that communication that occurs is generally dominated by parents through a
one-way communication style, without providing a space for discussion for
children. In some cases, children tend to follow their parents' decisions due to social
pressure and power relations in the family. Communication adjustments also occur,
but it does not always guarantee openness and equality in communication. These
findings suggest that interpersonal communication plays an important role in early
marriage decision-making, and that communication adjustments may reflect
emotional dominance in family relationships.
