Abstract

Permasalahan keterlambatan penjemputan pasien oleh ambulans dapat terjadi akibat pemilihan rute yang kurang tepat, kondisi jalan yang bervariasi, serta jarak tempuh yang tidak efisien. Penelitian ini bertujuan untuk mengimplementasikan Algoritma A dalam menentukan jalur tercepat penjemputan ambulans di RSUD Aulia Pandeglang, Banten. Metode yang digunakan adalah pendekatan pencarian jalur terpendek berbasis graf, dengan titik lokasi direpresentasikan sebagai node dan jalan sebagai edge. Algoritma A* digunakan karena mampu mencari rute optimal dengan mempertimbangkan nilai biaya perjalanan dan estimasi jarak menuju tujuan melalui fungsi heuristik. Data yang digunakan berupa titik lokasi awal ambulans, lokasi penjemputan pasien, serta hubungan antarjalur yang tersedia. Hasil dari penelitian ini adalah rancangan sistem yang mampu memberikan rekomendasi jalur tercepat bagi ambulans sehingga proses penjemputan pasien menjadi lebih efektif dan efisien. Dengan adanya penerapan Algoritma A*, diharapkan pengambilan keputusan rute ambulans dapat dilakukan secara lebih cepat, tepat, dan mendukung peningkatan kualitas pelayanan kesehatan.

Abstract

Fuel consumption reduction remains an important issue in automotive engineering because it affects vehicle operating costs, energy efficiency, and carbon dioxide emissions. One of the practical factors influencing fuel consumption is tire inflation pressure. Under-inflated tires increase tire deformation and rolling resistance, which require additional engine power to maintain vehicle motion. This study aims to analyze the effect of tire inflation pressure variation on fuel consumption and estimated CO₂ emissions in a gasoline-powered light vehicle. The experimental design used four tire pressure levels, namely 26 psi, 30 psi, 33 psi, and 36 psi. Fuel consumption was measured using the full-to-full method on a fixed driving route under controlled operating conditions, including vehicle load, fuel type, route distance, and driving behavior. CO₂ emissions were estimated using a gasoline emission conversion factor. The experimental template shows that lower tire pressure tends to increase fuel consumption. At 26 psi, the vehicle recorded the highest fuel consumption, while pressure near the manufacturer’s recommendation produced lower fuel consumption. The estimated CO₂ emissions followed the same pattern because they were directly proportional to the amount of gasoline consumed. These findings indicate that tire pressure maintenance can contribute to fuel efficiency improvement and emission reduction without requiring modification of the engine system. The main contribution of this study is the formulation of a simple experimental framework for evaluating tire pressure, fuel economy, and emission relationships in light vehicles. This research is relevant for automotive maintenance practice, energy efficiency studies, and sustainable transportation engineering.

Abstract

In mechanical engineering, the demand for lightweight and sustainable materials is gaining significant momentum, as the choice of material impacts the efficiency, energy usage, and environmental footprint of mechanical systems. Natural fiber reinforced polymer composites have many advantages like low density and renewability but they are not widely used due to moisture sensitivity and poor fiber–matrix bonding. In this study, an alkali treatment process of coconut fibers and their hybridization with E-glass fibers for structural and semi‑structural components application using an epoxy composite is investigated. The work is tested for its tensile, flexural, impact, specific strength and moisture absorption properties. Coconut fibers were processed with sodium hydroxide to increase the surface roughness and remove hydrophilic impurities from the fibers and composite laminates were prepared by a hand lay-up technique in which the fibers were cured at room temperature. Experimental study shows that the tensile and flexural strength, impact resistance and specific strength of natural fiber composites of hybridization with E‑glass fiber are significantly increased when compared to natural fiber composites without hybridization, mainly due to the bridging effect of E‑glass fiber and reduced fiber pull out and load transfer. The hybrid composite also demonstrates reduced water absorption, further enhancing its potential for lightweight applications where durability and environmental considerations are paramount. In summary, this study contributes to the progress of sustainable composite development by comprehensively uniting the fiber treatment, hybrid reinforcement, mechanical evaluation, and moisture resistance in a single experimental system.

Abstract

Drying is an important agricultural post-harvest operation which requires high energy input and produces inconsistent agricultural products quality by conventional methods. Alternatively, solar assisted heat pump drying can be provided which is more efficient by utilizing both renewable solar heat and heat pump dehumidification and heat recovery. In this study, an integrated drying kinetics, energy analysis and exergy evaluation framework are developed to evaluate the performance of solar-assisted heat pump dryer. The framework describes mathematically derived indicators to describe moisture reduction behavior, drying rate, energy consumption, coefficient of performance, specific moisture extraction rate, drying efficiency, and exergy efficiency. Illustrative results demonstrate that the system continuously reduces the moisture content while increasing the energy utilization in comparison to conventional hot-air drying, where the COP and the SMER are important transients measuring energy delivery for useful purposes and the ability to remove moisture, respectively. Exergy analysis also pinpoints the main exergy-irreversibility sources in the drying chamber and heat-transfer components. The study is overall an integrated mechanical-engineering approach that connects drying behavior, heat transfer, energy consumption and exergy losses for designing and optimizing sustainable and energy efficient dryers for agricultural and food processing applications.
