Abstract

Increasing the production capacity of the business unit at the Mis Hubbullah charity house to develop and improve the business unit so that it is expected to increase income that supports the Education program at the Mis Hubbullah charity house, one of the sources of animal protein that is widely consumed by the public, easy to obtain is fish and the price is cheap, but Fish quickly undergo a process of decay, so it is necessary to preserve fish. Preservation of fish aims to reduce the water content in the fish body so that it does not provide an opportunity for bacteria to breed. Fish undergo the process of decay quickly compared to other foodstuffs. To increase sales value and income, it is necessary to give a touch of innovation so that it can add business units and attract public interest. Therefore, in this community service activity, counseling was carried out on the diversification of processed catfish meat products into practical and more quality catfish nugget products. In addition, training on making catfish nuggets was conducted. Potential targets who will be given counseling are students from the Al-Ansar Mis Hubbullah Foundation.

Abstract

Magnetite (Fe3O4) nanoparticles are very promising to be applied as a drug delivery system (DDS) for cancer chemotherapy. In this research, the crystal growth of hydrothermal derived magnetite particles was studied by oriented attachment (OA) model. The OA model was used to investigate the mechanism and the statistical kinetic of crystal growth. The crystal diameter change as a function of time with different concentration was measured using XRD. Firstly, 0.3248 g FeCl3 and 1.1764 g of sodium citrate, as well as 0.3604 g urea were dissolved into 40 mL of distilled water in a reactor. Subsequently, the reactor temperature was maintained at 210 °C and reaction time of 3.5–12 h in an air oven. The morphology of obtained particles was characterized using TEM, whereas VSM was used to determine the magnetic hysteresis curve. The XRD pattern showed that magnetite was obtained at temperature 210 °C and 3.5 h reaction time, as well as its intensity increased with reaction time. The crystal size of Fe3O4 was 9.44 nm at 3.5 h and appropriate with the oriented attachment model. The magnetite nanoparticles with shaped core-shell size less than 50 nm and suitable for biomedical application especially as drug delivery.

Abstract

Efforts to increase sales of car/motorcycle polish products have been carried out by the Graphene Guard business incubator. This product is a downstream research result of lecturer/researcher at the Faculty of Engineering, Riau University. As a new product and not yet known to the public, special strategies are needed to increase sales. In the initial stage, an online and offline sales strategy was carried out, but apparently it did not show encouraging results even though promotions had been carried out. It was felt that a reseller strategy needed to be implemented. The reseller strategy, especially offline resellers, was addressed to the students at Riau University with attractive prices and bonuses. This strategy generated significant sales in a relatively short time. The phenomenon where offline reseller sales results were very different from conventional sales strategies reflecting the changes in consumer behavior and increasingly complex market dynamics. Reseller marketing strategies, especially when carried out by individuals or small groups, often conveyed a strong sense of personalization and trust. In this strategy, focus was given to product advantages, customer testimonials, and real interactions. This created high levels of trust in consumers, and allowed them to feel confident in purchasing the product. This strategy can be a valuable experience for marketing of new products.
