Abstract

This study aims to segment customers of a veterinary clinic using a combination of Recency, Frequency, Monetary (RFM) analysis and the K-Means clustering algorithm. Transactional data from December 2024 to April 2025 were processed to generate key customer features, followed by min-max normalization to ensure comparability across variables. The segmentation was conducted in AI Studio 2025, with cluster quality evaluated using cluster distance performance and Davies-Bouldin Index. The analysis resulted in four distinct customer segments: the majority were passive customers with low transaction frequency and spending, while a smaller group showed high purchasing activity and made a significant economic contribution. This study demonstrates the effectiveness of automated data mining tools in uncovering meaningful customer profiles in a veterinary service context. The results provide a practical basis for targeted marketing, customer retention strategies, and service improvement in veterinary clinics. This approach offers valuable insights for data-driven decision making and represents a novelty for veterinary service management in Indonesia. Keywords: Customer Segmentation, RFM Analysis, K-Means Clustering, Veterinary Clinic, Data Mining.

Abstract

Budidaya jangkrik merupakan salah satu alternative mata pencaharian yang semakin berkembang seiring meningkatnya permintaan jangkrik sebagai pakan burung, ikan hias, serta kebutuhan industri makanan dan farmasi. Namun demikian, masih banyak peternak yang menerapkan metode konvensional, khususnya dalam hal pengaturan suhu dan kelembapan kandang yang menjadi faktor penting dalam keberhasilan budidaya. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk memberdayakan peternak jangkrik lokal di Desa Toapaya, Kabupaten Bintan, melalui penerapan sistem monitoring lingkungan berbasis Internet of Things (IoT) menggunakan platform Blynk dan mikrokontroler Arduino. Alat yang dirancang mampu memantau suhu dan kelembapan secara real-time serta mengirimkan notifikasi langsung ke perangkat pengguna, sehingga memungkinkan peternak untuk segera melakukan tindakan korektif saat kondisi kandang berada di luar batas ideal. Kegiatan ini meliputi observasi lokasi, wawancara, studi pustaka, perakitan alat, instalasi, pengujian, hingga evaluasi pasca implementasi. Hasilnya menunjukkan bahwa sistem dapat berfungsi secara efektif dalam menjaga kestabilan lingkungan kandang, menurunkan tingkat kematian jangkrik, serta meningkatkan produktivitas budidaya. Selain menghasilkan solusi teknologi praktis, kegiatan ini juga berkontribusi dalam membangun masyarakat cerdas dengan mendorong literasi teknologi di kalangan peternak daerah.

Abstract

Penelitian ini bertujuan untuk menemukan lokasi untuk galangan kapal di Bintan Timur yang menyediakan layanan pembuatan kapal baru dengan kedalaman 5 meter dan kapasitas antara 1000 sampai 5000 GT. Dari hasil survei lapangan, dua tempat yang menjadi opsi adalah Desa Galang Batang dan Desa Sungai Enam. Metode Analytical Hierarchy Process (AHP) dipakai untuk mengevaluasi kedua lokasi tersebut berdasarkan kriterianya seperti geografi, infrastruktur, modal, dan pasar. Hasil analisis menunjukkan bahwa Desa Galang Batang mendapatkan nilai lebih tinggi dengan skor 0,82 (82%), dan menurut peraturan pemerintah tentang zona industri, lokasi ini dianggap layak.

Abstract

Maritime transportation plays a vital role in mobility within archipelagic regions, and Fast Patrol Boat are an efficient choice to meet the needs of defence and maritime patrol in Indonesia. The innovation of adding bilge keels to the vessel is expected to enhance the performance of fast patrol vessels. This study aims to identify and evaluate the motions of Fast Patrol Boat to understand their performance under various sea conditions. Fast Patrol Boat operating at high speeds require a responsive pitch motion, making them well-suited for safeguarding Indonesia's archipelagic waters. The analysis results show that patrol Boat equipped with bilge keels perform better in terms of response and manoeuvrability, especially at high speeds, compared to vessels without bilge keels, although for other degrees of freedom such as heave and roll motions, there is no significant difference between the two types of vessels

Abstract

The Riau Archipelago is one of the provinces that geographically consist of 1700 islands surrounded by sea, both small and large, with a percentage of 98% sea and 2% land. So, to support the minimal health facilities on the Riau Archipelago, an Ambulance Boat is needed to mobilize patients to hospitals with better facilities. In this study, it aims to modify the design of the High Speed Landing Craft Boat Passenger to become an Ambulance Boat with a length of 12 m, a width of 3 m, a height of 1.2 m, and a draft of 0.6 m. Then perform technical calculations including hull shape coefficient analysis, stability, seakeeping, resistance, speed, ship power, and Motion Sickness Incidence (MSI) analysis. From MSI analysis with ISO 2631 parameters, the wave heading is divided into 5 sections: 00 (Following Seas), 450 (Stern Quartering Seas), 900 (Beam Seas), 1350 (Bow Quartering Seas), and 1800 (Head Seas). The value MSI is obtained after carrying out a comprehensive analysis, the results are depicted in the MSI chart for sea state 1 calm (0-0.1 m) and sea state 2 smooth (0.1-0.5 m) conditions with the following wave directions, waves coming from the side (beam seas), and waves coming from the front (head seas).

Abstract

Perajin bambu di UMKM binaan PokDarWis Desa Pengudang Kabupaten Bintan belum memiliki daya jual yang optimal secara menyeluruh. Berdasarkan kondisi di daerah tersebut, pelaku UMKM lebih memilih menerapkan sistem Make-to-Order (MTO). Dalam jangka waktu yang ditentukan, metode tersebut belum menemukan solusi yang optimal. Dengan adanya permasalahan tersebut, perubahan diperlukan dalam penentuan rute logistik untuk mengurangi biaya transportasi. Metode Operation Chart dan Line Balancing dipilih dalam penelitian ini untuk mencapai tujuan optimal dalam implementasi line balancing sehingga setiap stasiun kerja dapat bekerja secara efektif dan efisien. Terdapat peningkatan signifikan dalam jumlah stasiun kerja setelah penelitian ini dilakukan. Setelah menerapkan metode Line Balancing, data Line Efficiency (LE) yang didapatkan adalah 71,94% dari total waktu kerja stasiun. Balance Delay (BD) memiliki nilai sebesar 35%, dan jumlah stasiun kerja yang seimbang adalah 21,46 dari total 40 elemen kerja. Oleh karena itu, perlu dilakukan beban kerja yang adil dari operator dengan menyediakan pekerjaan untuk operator tidak ditempati sehingga semua pekerjaan dapat diselesaikan.

Abstract

The development of transportation infrastructure has a multidimensional impact in driving economic growth and regional integration. The Jakarta-Bandung High-Speed Rail project is expected to reduce traffic congestion and improve connectivity and mobility efficiency. However, its success must be assessed not only from the technical aspects and physical completion, but also the effectiveness of public investment, long-term economic impacts, and environmental sustainability. The main challenges of this project include land acquisition, financial uncertainty due to debt-based financing schemes, and integration with other transportation systems. From a social perspective, this project has the potential to drive urbanization around the route, but also poses the risk of development inequality and gentrification. Ecological impacts are also a concern, especially in terms of land degradation and operational energy consumption. This study uses a literature study method with content analysis to evaluate the success of the project based on economic, social, and environmental indicators. The results of the study show that the effectiveness of this project is highly dependent on operational optimization, integration of transportation modes, and the sustainability policies implemented. With transparent governance and appropriate risk mitigation strategies, this project has the potential to provide long-term benefits for economic growth and community welfare, as well as being a model for more inclusive and sustainable transportation infrastructure development in Indonesia.
