Sistem Akuarium Auto Cleaning Berbasis IoT Implementasi Smart City
(Politeknik Negeri Batam, 2026-03-31) Herpiyana, Yunika; Mahdaliza, Rahmi
This research discusses the design of an Internet of Things (IoT)-based auto- cleaning aquarium system as an automated solution for monitoring and maintaining aquarium water quality. The system is designed using an ESP32 microcontroller integrated with a 4205C pH sensor, a SEN0189 turbidity sensor, and an HC-SR04 ultrasonic sensor to monitor acidity, turbidity, and water level in real-time. Sensor data is displayed on a 16x2 LCD, while the water draining and filling process is controlled automatically using a DC pump through a relay module. Test results show that the system is able to work well according to the designed logic, where the water will be drained when it is detected as cloudy or the pH is outside the ideal limit, and refilled until it reaches the specified level. This system is proven to have good accuracy and reliability in maintaining aquarium water quality, thus increasing maintenance efficiency, reducing manual intervention, and supporting the implementation of the Smart City concept through automation and IoT connectivity. The system has a good level of accuracy and reliability in maintaining aquarium water quality. The pH sensor has a low error rate (0.44%– 4.62%), the turbidity sensor shows an average error of around 1–2%, and the ultrasonic sensor has optimal accuracy in the mid-range range. Thus, the system is considered reliable in monitoring and maintaining aquarium water quality according to predetermined parameters.

PERAN CITRA MEREK DALAM MEDIASI PEMASARAN DIGITAL DAN HUBUNGAN DENGAN PELANGGAN TERHADAP KEPUTUSAN MEMILIH POLITEKNIK NEGERI BATAM SEBAGAI PERGURUAN TINGGI TUJUAN
(Politeknik Negeri Batam, 2026-03-10) Khautal, Adani; Khusniah, Riza
This study aims to analyze the influence of Digital Marketing and Customer Relationship on the decision to choose Batam State Polytechnic, with Brand Image as a mediating variable. Amidst the increasingly tight competition in higher education and the changing behavior of selective prospective students, marketing and relationship management strategies have become crucial. This research employs a quantitative explanatory approach. The sample consists of 100 new students from the class of 2025/2026, selected using the proportionate stratified sampling technique. Data were collected through questionnaires and analyzed using Partial Least Squares - Structural Equation Modeling (PLS-SEM). The results indicate that Digital Marketing has a significant direct influence on the Decision to Choose, but does not significantly affect Brand Image. Conversely, Customer Relationship has a significant influence on Brand Image but no significant direct influence on the Decision to Choose. Another key finding is that Brand Image acts as a full mediator in the relationship between Customer Relationship and the Decision to Choose. This study recommends that Batam State Polytechnic strengthen service interactions to build a positive brand image while consistently utilizing digital channels for direct persuasion.
PENGARUH AKSESIBILITAS WEBSITE POLIBATAM.AC.ID TERHADAP PERSEPSI PENERIMAAN PENGUNJUNG
(Politeknik Negeri Batam, 2026-01-21) Ferari, Abi Hakim; Sibagariang, Swono
Penelitian ini mengkaji bagaimana aksesibilitas situs web pada domain polibatam.ac.id memengaruhi persepsi pengguna secara umum. Sebagai portal informasi publik yang vital, situs web Politeknik Negeri Batam sangat penting dalam menyediakan akses yang setara, terutama bagi pengguna disabilitas. Evaluasi dilakukan menggunakan standar WCAG 2.1 dan perangkat WAVE, yang dilanjutkan dengan desain ulang strategis untuk meningkatkan pengalaman pengguna. Untuk menilai dampaknya, pendekatan kuantitatif diterapkan dengan menyertakan variabel seperti persepsi kemudahan penggunaan, kegunaan, dan sikap pengguna. Data yang dikumpulkan dari 34 responden telah divalidasi melalui uji reliabilitas yang ketat. Analisis statistik melalui uji-T menghasilkan nilai signifikansi p < 0,001, yang membuktikan bahwa aksesibilitas secara signifikan memengaruhi cara pengguna memandang sistem tersebut. Temuan ini menunjukkan bahwa memprioritaskan aksesibilitas melampaui sekadar kepatuhan teknis, hal ini secara langsung meningkatkan kenyamanan pengguna, mendorong inklusivitas, dan memperkuat reputasi digital institusi. Akhirnya, penelitian ini memberikan referensi komprehensif untuk mengembangkan platform akademik yang lebih berpusat pada pengguna dan inklusif.
Manajemen Pengelolaan Barang Dan Gudang Khususnya Material Piping Di PT Patria Maritim Perkasa
(2025-10-15) Fikri Jibran Muhammad T; Harlan Bestario Fandy
This industrial internship and study report was conducted at PT Patria Maritim Perkasa (PMP), a shipbuilding and engineering company operating in the maritime industry. The internship was carried out in the Warehouse/Main Store division, focusing on warehouse management of piping materials used in ship production. The study aims to identify storage inefficiencies caused by overstock conditions, limited pipe rack capacity, and the absence of a fixed bin location system, which resulted in extended lead time, data inaccuracies, and increased occupational safety risks. The research applied a descriptive qualitative approach supported by light quantitative analysis using stock data and storage capacity calculations. Data were collected through structured observation, semi-structured interviews with warehouse operators and administrators, and analysis of SAP ERP inventory reports. The findings revealed that several piping materials experienced overcapacity exceeding 100 units per item, while existing pipe racks could only accommodate approximately 60–70% of incoming volume. To address these issues, a warehouse relayout and structural modification of 13 piping stands (Type A and Type B) were proposed, increasing storage capacity by ≥40% without expanding the physical area. Additionally, the integration of a Fixed Bin Location system into the SAP ERP (Warehouse/Material Management Module) was recommended to improve inventory accuracy and reduce material searching lead time. A standardized Material Handling SOP aligned with Occupational Health and Safety (OHS/K3) principles was also developed to minimize manual material handling risks. The proposed solutions are expected to enhance warehouse efficiency, improve stock accuracy, reduce operational lead time, and strengthen safety compliance, thereby supporting smoother ship production activities in the long term.
