Abstract

Indonesia produces many types of textile products, such as clothing and custom fabrics often with unique patterns. To generate the patterns, there are many methods, including eco-printing by pounding process. However, the process, which was later referred to as eco-pounding, requires much time and energy, which can have a negative impact, such as musculoskeletal disorders, on the human body. To address this issue, the present work proposes a machine that can help the process of eco-pounding. Shigley’s method is applied to guide the design process of the machine. The design and manufacturing processes of the eco-pounding machine are presented, in which three machine design models are first introduced and then analyzed for finalization by benchmarking method. Subsequently, a machine model that uses a so-called quad-cliff mechanism is selected for manufacturing and testing. As a result, the proposed machine can achieve the design requirements that were set. Three pounding movements per second can be obtained by the machine, with possible increases by an engine upgrade. This machine can be considered a prototype for a semi-automatic eco-printing process by pounding technique.

Abstract

The depletion of petroleum reserves, rising fossil fuel demand, and increasing plastic waste pollution highlight the need for alternative fuels. This study investigated the performance and exhaust emissions of a direct-injection diesel engine fueled with waste cooking oil biodiesel blended with plastic pyrolysis oil at concentrations of 5%, 10%, 15%, and 20% (B+A5 to B+A20). Biodiesel was produced through degumming, esterification, and transesterification, while plastic pyrolysis oil was obtained via thermal cracking. Engine tests under a constant load across a range of engine speeds evaluated brake power, brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust emissions. The results indicate that increasing the proportion of plastic pyrolysis oil improved engine performance compared to pure biodiesel. The B+A20 blend provided the best overall performance, with 44.4% higher power output, 39.6% higher BTE, and 30% lower BSFC than biodiesel, although performance remained below conventional diesel. Regarding emissions, B+A20 reduced CO by 16.3% relative to biodiesel and slightly reduced CO₂ (1%), while NOx increased by 59.7%, highlighting a trade-off between improved performance and NOx control. Overall, blending waste cooking oil biodiesel with plastic pyrolysis oil enhances renewable fuel performance and valorizes plastic waste, but further measures are needed to mitigate NOx emissions.

Abstract

Biofuel production and its properties improvisation are the wide areas of research in internal combustion (IC) engines. This research derived biofuel from industrial chicken waste. Nanofuels were produced in this study by adding 40 nm-sized nanoparticles of carbon nanotube (CNT) and manganese oxide (MnO) with a variation of 100 to 200 ppm to the derived oil. Four fuel blends (biofuel (B), B with CNT, B with MnO, and B with CNT+MnO) were compared to the performance of diesel fuel in a 3.5 kW CI engine. The combustion process (peak pressure and heat release), brake thermal efficiency (BTE), and exhaust emissions (CO, HC, NOx, and CO2) were used as parameters to evaluate the fuel’s performance. The result revealed that nanofuel outperformed both diesel fuel and biofuel. The addition of 200 ppm CNT in biofuel enhanced the fuel properties, resulting in higher BTE by 28% and 9.7% compared to diesel fuel and biofuel. The CNT-biofuel also generated fewer emissions compared to diesel fuel by 26%, 9.4%, and 25% for NOx, HC, and CO gases respectively.

Abstract

Rubber Seed Biodiesel (RSB) and Plastic Pyrolysis Oil (PPO) deserve to be considered as alternative fuels for diesel engines, because of their advantages such as large raw material resources, derived from free or waste feedstock and the use of plastic waste as fuel can prevent environmental pollution. Due to their almost identical densities, RSB and PPO can be mixed homogeneously. In general, the use of a mixture of RSB and petroleum diesel in diesel engines shows positive performance, both engine performance and emissions, as well as the use of mixed PPO and diesel fuel. Although RSB has a good cetane number and flash point, on the other hand, RSB also has disadvantages in its physiochemical properties, such as low oxidation stability, high acid value, low heating value, and high viscosity. Likewise, PPO has good oxidation stability, acid value, and viscosity, but the flash point, CO, and HC emissions are also bad. This article tries to describe the opportunity to mix RSB and PPO, to find the best composition between RSB and PPO which shows the best fuel physiochemical properties and engine performance.

Abstract

Jatropha Curcas stands out as a promising plant-based feedstock, offering a non-edible oil that holds great potential as an alternative fuel to traditional diesel. Notably, Jatropha oil boasts favourable fuel properties, including a higher oil content compared to other alternatives. This attribute makes it an attractive candidate for biodiesel production. Importantly, as a non-edible oilseed feedstock, Jatropha Curcas helps mitigate concerns related to food prices and the ongoing food versus fuel debate, offering a sustainable solution to the growing energy demands. Furthermore, the plant exhibits impressive yields, with the potential to produce up to 40% oil weight per seed. This high yield not only enhances the economic viability of Jatropha-based biodiesel but also underscores its efficiency as a feedstock. The discussion extends beyond mere fuel properties, encompassing a comprehensive comparative review that delves into engine performance and emission characteristics associated with Jatropha Curcas. The novelty of this paper lies in its exploration of the crude oil aspects of Jatropha curcas, shedding light on an essential facet often overlooked. By presenting a thorough analysis of fuel properties, engine performance, and emission characteristics, the paper contributes valuable insights to the discourse on sustainable energy solutions. Moreover, it goes beyond technical aspects and provides perspectives on the current economic status, offering a holistic view of the potential impact of Jatropha Curcas in the broader context of renewable energy and economic development.

Abstract

Kegiatan pengabdian pada penerapan teknologi panel surya pada trainer rangkaian listrik untuk mendukung program kemandirian energi di SMP Swasta PGRI 3 Medan, dilatarbelakangi oleh kurangnya pemahaman guru dan siswa terhadap pemanfaatan panel surya sebagai sumber energi listrik terbarukan, serta belum tersedianya media praktik atau trainer rangkaian listrik yang memadai di sekolah mitra. Selain itu, guru dan siswa belum pernah memperoleh pelatihan teknis terkait penerapan panel surya dalam pembelajaran kontekstual, sehingga belum dapat mengintegrasikan konsep energi terbarukan secara praktis dalam kegiatan belajar mengajar. Kegiatan ini bertujuan untuk meningkatkan wawasan, keterampilan, dan kemampuan aplikatif guru dan siswa dalam memahami dan mengoperasikan sistem panel surya, serta menyediakan media pembelajaran berupa trainer panel surya sebagai sarana praktik. Metode pelaksanaan kegiatan meliputi pendekatan ceramah untuk penyampaian konsep dasar energi surya, diskusi dan tanya jawab untuk memperdalam pemahaman peserta, demonstrasi alat untuk memperlihatkan prinsip kerja sistem panel surya. Tahapan kegiatan diawali dengan survei kebutuhan mitra, perancangan dan pembuatan modul trainer panel surya dan rangkaian listrik, pelaksanaan pelatihan, dan evaluasi hasil kegiatan. Hasil kegiatan menunjukkan peningkatan pemahaman dan keterampilan peserta terhadap konsep dan penerapan panel surya dalam sistem kelistrikan sederhana. Selain itu, kegiatan ini turut menumbuhkan semangat kemandirian energi serta mendukung pengembangan pembelajaran berbasis proyek di lingkungan sekolah.
