Abstract

Abstract. Penelitian ini menyajikan evaluasi eksperimental terhadap kinerja pompa sentrifugal tipe GP-125 pada tiga konfigurasi operasi, yaitu tunggal, seri, dan paralel. Pengujian dilakukan dengan variasi kecepatan putaran (712,5 rpm, 1.425 rpm, dan 2.850 rpm) serta pembukaan katup (1/4, 1/2, 3/4, dan penuh). Parameter utama yang dianalisis mencakup head total, debit aliran, dan efisiensi pompa. Hasil eksperimen menunjukkan bahwa konfigurasi paralel menghasilkan debit tertinggi dengan nilai maksimum 0,000967 m³/s pada kecepatan 2.850 rpm, sedangkan konfigurasi seri memberikan peningkatan signifikan pada head hingga 19,60 m. Efisiensi terbaik diperoleh pada konfigurasi paralel dengan nilai 0,34% pada katup penuh. Temuan ini menegaskan pentingnya pemilihan konfigurasi pompa yang tepat sesuai kebutuhan sistem, baik untuk aplikasi yang memerlukan debit besar maupun head tinggi.

Abstract

Corn cultivation in Indonesia continues to face challenges related to productivity and operational efficiency. According to data from the Central Bureau of Statistics, in 2023, the harvested area of corn was approximately 2.48 million hectares, with total production of 14.77 million tons, representing a decline of more than 10% compared to the previous year. This decline indicates that conventional planting methods have not fully met the demands for efficiency and sustainability in modern agricultural systems. One emerging technological innovation is the utilization of Unmanned Aerial Vehicles (UAVs) in agricultural practices. UAV technology has previously been applied for pest control and shows strong potential for expansion into fertilization and seed distribution. This study aims to design and evaluate a UAV-based system for efficient and accurate corn seed broadcasting. The research methods include hardware design, integration of an automated control software system, and field testing to assess the technology's reliability and performance. The results show that the UAV system can distribute corn seeds with an accuracy of approximately 92–96%, higher than that of conventional methods. In addition, planting efficiency significantly improved, with one hectare of land being planted within 35–45 minutes compared to 18–25 hours using manual methods. The implementation of UAV technology also reduces labor requirements, improves operational efficiency, and supports the adoption of more modern and sustainable agricultural practices.

Abstract

Modern technological progress has inspired numerous innovations that enhance efficiency in human activities, with agriculture remaining one of the most vital sectors for sustaining national economies. Appropriate technologies increase productivity while reducing dependence on traditional practices that demand excessive time and labor. This research presents the design and development of an agricultural drone created for seed spreading. The system employs a 300 Rpm DC motor that drives a propeller to ensure even seed distribution. Performance evaluation compared manual seed spreading and the drone-based method. Results demonstrated that manual spreading required an average of 3.33 hours per kilogram of seeds, whereas the drone accomplished the same task within 1 minute 20 seconds (80 seconds) per kilogram. These findings confirm that drone-assisted seeding offers an efficient and practical approach that supports the advancement of modern agriculture.

Abstract

This paper presents the experimental development and evaluation of a PIC16F877A-based intelligent controller for voltage regulation and load prioritization in standalone photovoltaic (PV) home energy systems. The proposed system integrates a photovoltaic panel, battery storage, inverter, and embedded controller into a unified platform for efficient energy management. The controller continuously monitors battery voltage using an analog-to-digital converter and implements a threshold-based control strategy to disconnect non-critical loads when the voltage drops below 11.7 V. Experimental results show that the PV system maintains stable voltage characteristics within approximately ±3%, while the output current varies significantly with solar irradiance, exhibiting fluctuations of more than 60% under varying environmental conditions. The proposed controller effectively regulates system operation by dynamically managing load distribution, thereby preventing deep battery discharge and improving overall system reliability. In addition, the integration of auxiliary subsystems, such as automatic lighting and motion detection, enhances energy efficiency by reducing unnecessary power consumption. The findings demonstrate that the proposed low-cost PIC-based controller provides a practical and effective solution for intelligent energy management in standalone PV systems, particularly in off-grid residential applications.

Abstract

Mobile robot path tracking is a fundamental problem in control systems and robotics and has been widely utilized as a platform for integrating multidisciplinary concepts in mechatronics education. This study proposes an experiential learning framework for mobile robot control using a PID-based path tracking approach. The framework integrates theoretical control principles with hands-on implementation through the development of a differential-drive mobile robot equipped with reflective sensor arrays and a microcontroller-based control unit. The PID controller is applied to regulate robot motion based on real-time feedback, and its parameters (Kp, Ki, Kd) are tuned experimentally using a structured trial-and-error procedure. Experimental results indicate that the PID controller improves tracking stability and reduces oscillatory behavior compared to proportional-only control. The optimal parameter configuration (Kp=0.8, Kd=0.32, Ki=0.2) achieves stable tracking performance across different trajectory conditions, including curved paths. From an educational perspective, the proposed framework supports experiential and project-based learning by enabling systematic analysis of control system behavior through iterative experimentation. This work provides a practical and scalable approach for integrating control theory and robotic implementation in mechatronics education.

Abstract

Abstrak. Penggunaan plastik jenis Low Density Polyethylene (LDPE) dalam kehidupan sehari-hari berkontribusi besar terhadap peningkatan limbah padat di Indonesia. LDPE sulit terurai secara alami sehingga berpotensi menimbulkan pencemaran lingkungan. Penelitian ini bertujuan menganalisis pemanfaatan limbah plastik LDPE sebagai bahan substitusi pasir dalam pembuatan paving block, serta mengetahui pengaruhnya terhadap kuat tekan. Dua sampel paving block dibuat dengan komposisi berbeda, yaitu: (1) plastik dan oli (85%:15%) dan (2) plastik, pasir, dan oli (50%:35%:15%). Metode pengujian mengacu pada SNI 03-0691-1996 mengenai bata beton. Hasil pengujian menunjukkan bahwa kuat tekan paving block sampel 1 adalah 2,07 MPa, sedangkan sampel 2 mencapai 2,37 MPa. Peningkatan kuat tekan pada sampel 2 dipengaruhi oleh densitas pasir yang lebih tinggi (1400 kg/m³) dibandingkan plastik (0,91 g/cm³) dan oli (870 kg/m³). Walaupun nilai kuat tekan belum memenuhi standar mutu D (8,5 MPa), penelitian ini membuktikan bahwa penambahan pasir pada komposisi paving block plastik dapat meningkatkan performa mekanis produk.

Abstract

Abstrak. Aluminium 1100 memiliki ketahanan korosi dan konduktivitas tinggi, namun kekerasan permukaannya relatif rendah (±22 HB). Penelitian ini bertujuan menganalisis pengaruh proses pack carburizing menggunakan arang kayu pada suhu 600°C dengan variasi waktu tahan 2 dan 3 jam terhadap kekerasan Aluminium 1100. Spesimen didinginkan menggunakan oli ISO VG 32 dan diuji dengan metode Brinell (500 kgf, Ø10 mm). Hasil menunjukkan bahwa pemanasan tanpa karbon menurunkan kekerasan hingga ±15 HB akibat rekristalisasi dan pertumbuhan butir. Sebaliknya, perlakuan dengan karbon meningkatkan kekerasan menjadi ±23,33 HB (2 jam) dan ±25 HB (3 jam). Waktu tahan 3 jam menghasilkan nilai kekerasan tertinggi. Proses pack carburizing pada suhu 600°C terbukti mampu meningkatkan kekerasan permukaan Aluminium 1100 secara moderat dibandingkan perlakuan panas tanpa karbon

Abstract

efisiensi termal dan konsumsi energi pembangkit listrik. Penerapan thermal jacket dengan material isolasi yang tepat menjadi salah satu solusi untuk meminimalkan kehilangan panas pada permukaan turbin bersuhu tinggi. Penelitian ini bertujuan menganalisis dan membandingkan kinerja termal lima jenis material isolasi, yaitu Glasswool, Silica, Needle Mat, Knitmesh, dan PTFE Fiberglass, pada aplikasi thermal jacket turbin uap. Metode penelitian menggunakan pendekatan eksperimental dan analisis teoritis berdasarkan hukum konduksi panas Fourier satu dimensi dalam kondisi tunak. Model pengujian berupa silinder baja karbon berdiameter 200 mm dan panjang 400 mm yang dipanaskan hingga 1200°C, dengan suhu lingkungan 30°C. Variasi ketebalan isolasi yang diuji adalah 50 mm, 75 mm, dan 100 mm. Hasil analisis menunjukkan bahwa laju perpindahan panas berbanding lurus dengan konduktivitas termal material dan berbanding terbalik dengan ketebalan isolasi. Knitmesh menghasilkan laju perpindahan panas terendah sebesar 2340 W pada ketebalan 50 mm dengan konduktivitas termal 0,10 W/m·K. Needle Mat menunjukkan performa yang mendekati dengan laju perpindahan panas 2808 W pada ketebalan yang sama. Sebaliknya, Glasswool dan Silica menunjukkan laju perpindahan panas yang lebih tinggi. Pemilihan material isolasi yang tepat terbukti berpengaruh signifikan terhadap reduksi kehilangan panas dan peningkatan efisiensi termal sistem. Knitmesh direkomendasikan untuk aplikasi suhu tinggi pada turbin uap, sedangkan Needle Mat dapat menjadi alternatif dengan pertimbangan optimasi biaya. biaya

Abstract

Centrifugal pumps are the main component in pumping systems that are widely applied in industry, agriculture, and practical activities in engineering laboratories. This study aims to design and build a centrifugal pump tester with single, series, and parallel configurations as a learning medium in the Mechanical Engineering Laboratory. This tool uses two National TRANS GP-125 pump units with a discharge specification of 30 L/minute and a power of 125 W. The research method includes the stages of design, fabrication, testing, and technical calculations including total head, major and minor pressure losses, and impeller dimension analysis. The test results show that the parallel configuration increases the discharge capacity, while the series configuration is superior in producing higher heads. The system efficiency reaches 69%, still within the standard range of pump efficiency (63–84%). This study produces interactive learning media that can help students understand the working principles of centrifugal pumps and the effect of system configuration on hydraulic performance.
