Abstract

Product diffusion of very few layers of graphene (VFLG) and its derivative (car/motorcycle polish) has been carried out by the Graphene Guard business incubator. The steps and strategies began with discussions in a discussion group forum (FGD) inviting experts in order to find the best marketing patterns. In this case the Canvas method was chosen as a marketing strategy. As a follow-up to the results of the FGD, several activities were carried out. Improvements to the system and production capacity were carried out by adding production equipment, innovating production systems and creating production automation systems. The next step was to design brand and logo activities as well as product labels. The design and manufacture of online and offline sales systems were carried out to follow up on increasing production capacity. To increase the effectiveness of marketing, promotional activities were carried out in the form of advertising, creating brochures, production videos and participating in exhibitions. The results obtained indicated that the marketing of the new intermediate product, very few layer graphene (VFLG) and its derivative products in the form of car polishes, was still experiencing diffusion problems, as evidenced by the low sales capacity. This was realized because this product was a new product and was not yet known to the public. Especially for VFLG products, the additional obstacle was that this product was an intermediate product, thus only certain groups of people need it. Evaluation steps are needed for continuous improvement in order to continue to strengthen the diffusion of this product in society.

Abstract

Experiments were carried out to determine the performance of a direct expansion solar assisted heat pump water heater (DX-SAHPWH) which mainly consists of an evaporator panel with a surface area of ​​0.23 m2, a rotary compressor with an input power of 122.5 W, an insulated water tank that has been wrapped around a condenser with a diameter of 0.024 m and a length of 15 m and a capillary tube with a diameter of 0.001 m and a length of 1.61 m. Tests were carried out in open spaces, enclosed spaces and air-conditioned rooms exposed to direct sunlight. The results of this test are that the highest coefficient of performance (COP) on the DX-SAHPWH system is obtained at 1,25 and the smallest COP is obtained at 0.60. The higher intensity of solar radiation has a positive effect on the performance of the DX-SAHPWH system, which results in the heat transfer rate at water (Q wm) increases, the time required for heating is faster, and the COP of the DX-SAHPWH system increases.

Abstract

Pyrolysis is the heating of plastic waste at high temperatures with or without oxygen, producing oil, gas, and carbon residue. The use of catalysts in the pyrolysis process can accelerate the conversion of plastics, resulting in better-quality oil. This study aims to examine the potential of oil produced from the pyrolysis of Low-Density Polyethylene (LDPE) plastic with the addition of bentonite clay catalyst as an alternative fuel. The pyrolysis process was carried out experimentally at a temperature of 450 °C with a residence time of 60 minutes, and variations of catalyst composition of 0%, 5%, 10%, 15%, and 20% were tested to obtain the optimum condition. The composition that produced the highest oil yield was then tested at lower temperatures of 350°C and 400 °C with the same residence time. The optimum composition of bentonite clay catalyst was 15% at 450 °C. Without the catalyst (0% composition), the oil yield was 54.2%, which increased to 66% from a total feedstock of 500 g, and when compared to the plastic mass of 425 g, the oil yield reached 82.5%. The density of the oil was 0.766 g/ml, the viscosity was 1.53 cP, and the calorific value was 11302.33 cal/g. LDPE pyrolysis oil with bentonite clay catalyst showed characteristics closer to diesel fuel and kerosene. Thus, LDPE pyrolysis oil has the potential to be used as an alternative substitute for diesel fuel in energy applications.

Abstract

Refrigerant is an essential working fluid in refrigeration system. However, the use of synthetic refrigerant such as R-134a is now restricted due to its high Global Warming Potential (GWP) value. As an alternative, MC-134 as hydrocarbon refrigerant offers more environmentally friendly solution. This research aims to compare the performance of R-134a and MC-134 in a vapor compression refrigeration cycle system, as well as analyze the influence of expansion devices, namely capillary pipes and Thermostatic Expansion Valves (TEV). The test results show that for R-134a, increasing the length of the capillary pipe, increases the Coefficient of Performance (COP) by 20.83% due to decrease in compression work. In contrast, for MC-134, there is  decrease in COP by 3.35%. TEV provides the best performance with an increase in refrigeration effect of 6.05% and COP of 25.07%. However, TEV is not suitable for MC-134 because the low condensing pressure inhibits the phase change to liquid. In the use of 1.25 m and 1.5 m capillary pipes, MC-134 even has a higher COP of up to 16.65% compared to R-134a. Despite this, MC-134 still shows potential as a replacement for R-134a, with 30% of the mass capable of producing twice the refrigeration effect and 7.52% lower electric current consumption.

Abstract

Thermoelectric cooler (TEC) based on the Peltier effect offers a compact, silent, and environmentally friendly portable cooling solution. It can be used to preserve perishable food, medicine on remote area with limited or no electricity. This review explores experimental and theoretical findings from studies published between 2015 and 2025, with focus on portable beverage applications. Key material advances (average ZT ≈ 1–1.4) are traced, dominant thermal management bottlenecks are identified, and emerging optimization methods including artificial intelligence-assisted design are discussed. The system coefficients of performance (COPs) reported for one-stage beverage coolers have remained modest (0.2–0.9). However, recent prototypes have demonstrated the capability to achieve drink temperatures below 5 °C from 25 °C ambient within 30 minutes. These prototypes also show promising pathways for higher efficiency through hybrid photovoltaics, advanced heat sinks, and adaptive control.

Abstract

The direct solar dryer has been tested for drying bananas under different conditions. The dryer being tested is a hybriddryer that can be used with other energy sources, in addition to using solar energy as the main energy source during theday, while LPG gas is used for drying at night. The results showed that the highest temperature, the highest decrease inwater content in the test with LPG was obtained on shelf 6, while the lowest was obtained on shelf 1, because the heatsource was at the bottom of the dryer on shelf 6, the opposite happened to dry using solar energy because the heat sourcecame from the top of the shelf 1. In testing with LPG, the highest temperature that can be achieved is 84.7 ° C, on shelf6, while the lowest temperature is 52.3 ° C on shelf 1, on the other hand, the temperature of bananas using solar poweris the highest temperature on the shelf 1 at 11.00 WIB at 62.9 ° C and the lowest on shelf 1 at 17.00 WIB at 37.1 ° C. Thetotal energy requirement for drying in the test using LPG was 4681.92 kJ, while the total energy requirement for dryingin the test using solar power was 3176.24 kJ. Drying using solar energy is more economical than using LPG gas, but thedrying time is longer than LPG. Drying using a dryer technology have better quality and hygienic than open sun drying.

Abstract

Pengujian mesin AC (Air Conditioning) hibrida (pemanfaatan sisi pendinginan dan sisi pemanasan sekaligus) pada pengoperasian standby mode (tradisional AC) dengan kondisi tanpa beban pendinginan dan dengan beban pendinginan 1000 Watt telah dilakukan pada penelitian ini. Kinerja AC hibrida pada kondisi tanpa beban dibanding kondisi dengan beban 1000W adalah rata-rata COP (Coefficient of Performance) sekitar 2,460 berbanding 2,452, PF (Performance Factor) sekitar 3,42 berbanding 3.41 dan TP (Total Performance) sekitar 5,88 berbanding 5,86. Hasil pengujian menunjukkan bahwa dengan beban pendinginan 1000 Watt mampu memberikan temperatur ruang pendingin rata-rata sebesar 28,3 °C, temperatur ruang pemanas 44,9 °C, kerja kompresor 0,5825 kW sedangkan pada kondisi tanpa beban pendinginan, temperatur ruang pendingin rata-rata sebesar 22,5 °C, temperatur ruang pemanas 38,8 °C, kerja kompresor 0,5449 kW. Hasil pengujian mesin AC hibrida dengan refrigeran HCR-22 menunjukkan bahwa kondisi tanpa beban pendinginan memiliki performansi tidak jauh berbeda dibanding dengan beban pendinginan 1000W. Hal ini menunjukkan temperatur ruang pendingin dengan beban pendinginan 1000 Watt menjadikan temperatur ruang pendingin dalam kondisi jauh dari rasa nyaman bagi penggunanya, sehingga beban pendinginnya harus dikurangi atau kapasitas pendinginannya dinaikkan
