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.
