Abstract

Peningkatan nilai manfaat dari buah sukun salah satunya adalah melalui proses diversifikasi buah sukun menjadi tepung sukun. Proses pengolahan daging buah sukun menjadi tepung sukun harus melalui beberapa tahapan proses, satu diantara sekian tahapan yang paling krusial adalah proses pengeringan daging buah sukun. Hal ini dikarenakan proses pengeringan, khusunya pada pengeringan konvensional, sangat dipengaruhi oleh kondisi cuaca. Tujuan dari kegiatan ini adalah desiminasi teknologi tepat guna (TTG) berupa alat pengering berbahan bakar liquefied petroleum gas (LPG) guna menjawab permasalahan pengeringan konvensional yang sangat rentan terhadap perubahan cuaca. Mitra yang dilibatkan di dalam kegiatan ini adalah Kelompok Tani Sumber Rejeki Purwosari yang beralamat di Dk. Kedungjangan, Kelurahan Purwosari, Kecamatan Mijen, Kota Semarang. Metode kegiatan yang diterapkan adalah pendekatan Participatory Rural Appraisal (PRA) dengan target utama proses alih teknologi alat pengering. Hasilnya, kegiatan ini memberikan gambaran dan pengetahuan baru terhadap mitra tentang bagaimana teknologi pengeringan, mulai dari tahapan perencanaan, pembuatan, uji kinerja, dan juga perawatan peralatan. Desiminisai TTG berupa alat pengering mampu menjawab tantangan pengeringan konvensional yang bergantung pada kondisi cuaca.

Abstract

One of the best ways to reduce food loss during harvest is drying. The main challenge in the drying process is reducing energy consumption as a heat source in drying equipment. Integrating thermal energy storage (TES) into drying equipment has proven to be an effective way to enhance energy efficiency in the drying process. This research aims to explore the potential of TES material in the form of aluminium chips sourced from machining waste and integrated into a drying device. The thermal characteristics of the drying system without and with the addition of TES are compared and evaluated under two testing conditions, namely charging and discharging. The results show that the integration of TES in the drying system can reduce the percentage of temperature drop in the drying chamber due to the charging-discharging process by 58.57%, with the average percentage of temperature drop in the drying chamber without and with the addition of TES being 25.56% and 10.59%, respectively. Overall, aluminium chips obtained from machining waste can be used as an alternative TES material that is environmentally friendly, inexpensive, and readily available.

Abstract

Solar drying technology has become a vital innovation for sustainable food preservation and renewable energy utilization, offering an energy-efficient alternative to conventional drying methods. This study provides a comprehensive bibliometric analysis of research trends, influential authors, key institutions, and geographical contributions in the field of solar drying technology from 2004 to 2024. We analyzed 108 relevant publications using the Scopus database and VOSviewer software, revealing a significant increase in research output since 2010, with a marked surge after 2016. India and China emerge as leading contributors, driven by their large agricultural sectors and favorable solar conditions. Key research efforts have focused on improving energy efficiency, optimizing drying processes, and preserving product quality. Despite these advancements, critical gaps remain, particularly in scaling solar drying systems and integrating hybrid technologies that combine solar energy with other renewable sources. This study highlights the importance of interdisciplinary collaboration to advance technological innovation and address challenges in food security and energy sustainability. Future research should focus on developing hybrid systems, finding better ways to store energy, and studying how solar drying affects the taste and nutritional value of food in order to make it more useful in a wider range of climates and farming situations.

Abstract

This study explores the dynamic response of passenger cars equipped with nonlinear passive shock absorbers, emphasizing the nonlinear damping characteristics over traditional linear models in simulating real-world driving conditions. To capture the nonlinear damping behavior, experimental data from a shock absorber testing apparatus was utilized to derive an empirical formula. The damping force was modeled using a seventh-order polynomial equation, accurately representing the force-velocity relationship. This nonlinear damping model was integrated into a half-car suspension model, which was subjected to simulations involving two road profiles: a bump and an irregular sinusoidal road profile. Simulations demonstrated that the nonlinear model outperformed its linear counterpart, particularly in vibration control. It achieved significant reductions in body displacement, body acceleration, and suspension deflection, with notable improvements at resonance speeds. Root Mean Square (RMS) analysis further corroborated the nonlinear model's superior damping performance, showing lower displacement and acceleration values compared to the linear model. The findings indicate the effectiveness of nonlinear damping models in enhancing ride comfort and vehicle stability, providing a more realistic and effective framework for vehicle dynamic analysis compared to conventional linear approaches.

Abstract

This study investigates the potential of utilizing vehicle vibrations as an energy source through a regenerative shock absorber (RSA) system based on a rack-pinion mechanism and electromagnetic generator. The research comprises two main stages: experimental testing of the RSA and its implementation into a numerical half-car suspension model. Experimental data were used to establish the relationship between translational velocity, damping force, voltage, and current. The average damping coefficient obtained was 827.33 Ns/m and was applied in simulations. The results indicate that the highest voltage and current outputs occur at a speed of 90 km/h, which corresponds to the largest suspension deflection amplitude. Simulation outcomes also demonstrate that the RSA effectively functions as both a vibration damper and an energy harvester. This study confirms the dual-functionality of RSA systems in improving ride comfort while simultaneously converting mechanical energy into electrical energy.

Abstract

The utilization of solar energy to support electric vehicle charging still faces challenges related to efficiency and real-time solar radiation monitoring. Addressing this issue is critical given the importance of optimizing renewable energy to facilitate the transition toward sustainable transportation. This study offers a solution through the development of an Internet of Things (IoT)--based solar radiation monitoring system capable of measuring solar light intensity in real time. The system employs a BH1750 sensor integrated with an ESP32 microcontroller to process data, transmit it to the Firebase Realtime Database, and display it via an Android application. The methodology encompasses the design, implementation, and testing of the system on an electric vehicle placed in an open area for 10 hours of observation. Results indicate that the highest light intensity, recorded at 98,321 lux, corresponded to solar radiation of 776.74 W/m², while the lowest light intensity, 69 lux, resulted in radiation of 0.55 W/m². The implications of this research include enhanced efficiency in electric vehicle charging, the advancement of IoT-based solar energy systems, and the potential integration with energy storage technologies and predictive algorithms to improve energy sustainability.
