Abstract

Desa Sumber Sari, Kabupaten Kampar, merupakan salah satu wilayah pertanian yang masih menghadapi permasalahan berupa serangan hama tanaman, ketergantungan petani terhadap insektisida kimia, serta belum optimalnya pemanfaatan limbah organik dari aktivitas pertanian dan rumah tangga. Kondisi ini mendorong perlunya alternatif teknologi sederhana berbasis sumber daya lokal yang ramah lingkungan, murah, dan mudah diterapkan oleh masyarakat. Kegiatan pengabdian ini bertujuan untuk mengimplementasikan teknologi pembakaran sampah bebas asap dalam mengkonversi limbah organik menjadi insektisida alami di Desa Sumber Sari, Kecamatan Tapung Hulu, Kabupaten Kampar. Metode yang digunakan adalah pendekatan partisipatif-terapan melalui tahapan identifikasi kebutuhan, perancangan alat sederhana berbasis prinsip pirolisis, pelatihan produksi asap cair, serta pendampingan aplikasi di lahan pertanian. Hasil kegiatan menunjukkan bahwa proses pembakaran terkendali mampu menghasilkan cairan kondensat dengan karakteristik menyerupai wood vinegar, yang mengandung senyawa asam organik dan fenolik dengan potensi insektisida. Variasi frekuensi pembakaran mempengaruhi kualitas produk, di mana kondisi optimum diperoleh pada pH 4–5 yang sesuai untuk aplikasi pertanian setelah pengenceran. Selain menghasilkan produk fungsional, kegiatan ini juga meningkatkan kapasitas teknis petani dalam mengelola limbah biomassa secara mandiri. Implementasi teknologi ini berkontribusi terhadap pengurangan limbah, penurunan emisi dari pembakaran terbuka, serta penguatan praktik pertanian berkelanjutan di tingkat lokal.

Abstract

Carbon capture is a vital strategy for mitigating climate change by reducing industrial CO2 emissions. Adsorption technology using microporous material shows significant promise. However, significant challenges persist in developing cost-effective and sustainable adsorbents. This study addresses this issue by simultaneously enabling CO2 adsorption and plastic waste utilization through activated carbon derived from polyethylene terephthalate (PET). It was evaluated under isothermal conditions (27°C, 35°C, and 45°C) at pressures up to 3500 kPa. The maximum CO2 adsorption capacity was 0.21313 kg/kg at 27°C and 3504.39 kPa, demonstrating the effectiveness of PET-derived activated carbon in capturing CO2. The Toth isotherm model exhibited a strong fit with experimental data, with an R2 of more than 99%. The Clausius-Clapeyron equation yielded an adsorption heat of 2223.66 kJ/kg using the Toth fitting, and the Chakraborty-Saha-Koyama model yielded a heat of 2383.65 kJ/kg, confirming strong adsorption potential. These results underline PET waste as a viable precursor for sustainable carbon capture adsorbents. Furthermore, the results provide essential data for developing numerical models to optimize adsorption-based carbon capture technologies.

Abstract

The implementation of the Closed Rotary Lemang Baking Machine at Rumah Lemang MSME in Pekanbaru improved burning time efficiency by 50%–62.5% per batch. However, field evaluation revealed a critical capacity gap: machine capacity (10 bamboo/batch) was significantly lower than traditional production capacity (40 bamboo/batch), resulting in lower actual throughput (6–7 bamboo/hour vs. 10–13 bamboo/hour) and reduced daily output (20–30 vs. 40 bamboo). This study analyzed this gap through throughput analysis and identified second-generation machine requirements using Voice of Customer (VoC). Methods included in-depth interviews with the MSME owner, production performance measurement, and comparative gap analysis. VoC results identified an ideal capacity of 50 bamboo/batch, with the owner already planning an independent modification as an indication of active technology adoption. This study recommends an iterative development approach with modular second-generation machine specifications grounded in real user needs.

Abstract

Indonesia is a country rich in marine catch, especially shrimp commodities, with a production volume reaching 1.12 million tons, but only 220 thousand tons or approximately 19.64%, are exported. One contributing factor to the low export rate is poor temperature control throughout the cold chain supply process. The aim of this study to design and develop an air blast freezing system with a capacity of 25 kg, and to compare the design results with experimental data. The main focus of the research is to increase the cooling system’s capacity to meet the demands of the cold chain in the storage of marine catch, while maintaining product temperatures consistently between -18 °C and -25 °C. The design results for the low-temperature cycle (LTC) yielded evaporator load of 788.66 W, compressor power of 221.78 W, condenser load of 1317.64 W, and an evaporator surface area of 4.84 m². For the high-temperature cycle (HTC), the evaporator load was 1499.76 W, compressor power was 159.61 W, condenser load was 948.27 W, and condenser surface area was 8.98 m². Experimental tests showed that the system was able to reach product temperatures between -19.6 °C and -25.3 °C, with a design COP of 2.014 and an actual COP of 2.413 for the cascade system

Abstract

Various countries are accelerating their energy transitions due to rising greenhouse gas emissions driving global climate change. The COP26 Conference set targets to limit global temperature rise to below 1.5 °C by 2030 and achieve net-zero emissions by 2050. Hydrogen is considered a promising alternative fuel because it produces only water vapor emissions and reduces dependence on fossil fuels. This study aims to analyze the effect of hydrogen gas, produced through electrolysis, mixed with Pertalite fuel on the performance of an internal combustion engine. The electrolysis process employed an Alkaline Electrolyzer Cell of the wet cell type, using a 30%wt NaOH electrolyte, a 12V power supply, and current variations of 40 A and 50 A. Engine performance parameters were evaluated under a brake load of 0.25 kg/cm². The results showed that at 40 A, the highest HHO gas production rate reached 0.9 Lpm, resulting in a 15.3% increase in effective shaft power, 5.7% thermal efficiency, 6.7% volumetric efficiency, 1.1% AFR, and a 29.06% reduction in BSEC. At 50 A, HHO gas production also reached 0.9 Lpm, with improvements of 18.3% in effective shaft power, 8.6% thermal efficiency, 10.8% volumetric efficiency, 2.84% AFR, and a 40.7% reduction in BSEC. These findings confirm that hydrogen blending enhances engine performance while supporting emission reduction.

Abstract

The increasing demand for food delivery systems that ensure product quality, freshness, and safety has driven the development of a Smart Food Container (SFC) integrated with Internet of Things (IoT) technology, utilizing a combination of Thermoelectric Cooler (TEC) and heat pipe as the primary temperature control mechanism. The design employs a TEC2-25408 module coupled with a copper heat pipe containing water as the working fluid, which efficiently transfers heat from the hot side of the TEC to maintain temperature stability while reducing the TEC’s workload. The integration of IoT technology using a NodeMCU ESP8266 enables real-time temperature monitoring and remote system control. The research process includes design, prototype fabrication, and experimental testing to evaluate system performance. The SFC prototype, with dimensions of 63 cm × 34 cm × 37 cm, consists of two compartments: a cooling section operating at 5–10 °C and a heating section operating at 50–70 °C. Based on experimental results indicate that the system achieves a design COP of 0.383 and an average experimental COP of 0.339 with a performance deviation of 11.38%.

Abstract

One of the widely used post-harvest processing methods for aloe vera is drying, given its high water content. An effective drying method is vacuum freeze-drying, although this method has a drawback in energy efficiency. This research examines the use of paraffin wax as a Thermal Energy Storage (TES) medium to utilize waste heat from the condenser during the freezing phase in a vacuum freeze-drying system. The results of the study show that the use of TES consistently improves drying efficiency and energy savings. The system with TES was able to remove a higher moisture content compared to the test without TES, at 68% for a 2 kg load versus 58.57% without TES. In addition, the Coefficient of Performance (COP) for the system with TES was recorded at 2.23, which is higher than the 2.08 without TES. The use of TES for 2 kg also resulted in an electrical energy saving of 259 Wh. Thus, TES in a vacuum freeze-drying system is effective in enhancing energy efficiency, reducing power consumption, and improving the drying performance of aloe vera.

Abstract

Hydrocarbon pipelines play a vital role in ensuring the continuous transportation of oil and gas. However, pipeline blockages remain a major operational challenge because of their significant impacts on safety, environmental protection, and production reliability. This study presents a literature review aimed at identifying and classifying the hazards and risks associated with hydrocarbon pipeline blockages using a 5×5 risk matrix based on the MIL-STD-882B military safety standard. Historical incident data from 1970–2024 were collected from the Pipeline and Hazardous Materials Safety Administration of the US Department of Transportation to support the risk assessment process. The analysis indicates that environmental damage is the most significant consequence of pipeline blockage incidents (28%), followed by fire and explosion (22%), toxic gas exposure (17%), overpressure (13%), economic losses (11%), and production losses (9%). Furthermore, environmental recovery costs account for approximately 88.6% of the total financial impact, while the probability of severe incidents reaches 80%, with estimated economic losses up to USD 20 million or production disruptions of 25%. The findings highlight the urgent need for effective mitigation and prevention strategies to improve pipeline integrity, operational safety, and sustainability within the oil and gas industry.
