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: The development of industries such as textiles, dyes, plastics, medicines, cosmetics, and others is increasing along with a rise in production, leading to a high amount of liquid waste generated. Non-biodegradable, toxic, and carcinogenic liquid waste can cause environmental pollution to surrounding water. To address this challenge, biomass waste such as palm kernel shells can be used to treat liquid waste by compositing it with photocatalyst materials. Therefore, this research aimed to obtain ZnO/graphene-like composites to degrade liquid waste. ZnO/Graphene-like composites were synthesized using the solvothermal method, followed by calcination. The performance test was carried out by varying the types of methylene blue, methyl orange, and phenol waste with an initial concentration of 10 ppm, alongside the variations of ultraviolet (UV) and mercury lamps. Subsequently, characterization was carried out using SEM, XRD, FTIR, BET, UV-Vis DRS, and UV-Vis Spectrophotometer. The results showed that the percent degradation of methylene blue under UV and mercury were 83.42% and 84.93 % respectively, while methyl orange in the same conditions was 94.83% and 97.17%, respectively. Furthermore, the percent degradation of phenol in UV light and mercury were 86.03% and 89.62%, respectively. This showed that the use of mercury lamps on methyl orange was more effective than UV lamps on methylene blue and phenol.Abstrak: Perkembangan industri seperti industri tekstil, pewarna, plastik, obat-obatan, kosmetik, dan lain-lain semakin meningkat dengan seiring bertambahnya jumlah produksi sehingga jumlah limbah yang dihasilkan juga meningkat salah satunya limbah cair. Limbah cair yang tidak dapat terurai secara biologis, beracun, dan karsinogenik ke perairan terdekat mengakibatkan pencemaran lingkungan. Disisi lain, limbah biomassa seperti cangkang sawit dapat dimanfaatkan untuk mengolah limbah cair, salah satunya mengkompositkan dengan material fotokatalis. Penelitian ini bertujuan memperoleh komposit ZnO/graphene-like untuk mendegradasi limbah cair. Komposit ZnO/Graphene-like disintesis dengan metode solvothermal dan dikalsinasi. Uji kinerja komposit ZnO/graphene-like dilakukan dengan menvariasikan jenis limbah methylene blue, methyl orange dan fenol dengan konsentrasi awal masin-masing 10 ppm serta dengan variasi lampu UV dan lampu merkuri. Komposit ZnO/Graphene-like dikarakterisasi menggunakan SEM, XRD, FTIR, BET, UV-Vis DRS dan UV-Vis Spektrofotometer. Hasil penelitian menunjukkan bahwa persen degradasi methylene blue di bawah sinar UV dan merkuri masing-masing sebesar 83,42% dan 84,93%, sedangkan methyl orange dengan sinar UV dan merkuri masing-masing sebesar 94,83% dan 97,17%. Selanjutnya, persen degradasi fenol dengan sinar UV dan merkuri masing-masing adalah 86,03% dan 89,62%. Hal ini menunjukkan bahwa penggunaan lampu merkuri pada methyl orange lebih efektif dibandingkan lampu UV pada methylene blue dan fenol.

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.

People consider inorganic waste to be useless even though it can be turned into beautiful crafts. Examples of crafts from inorganic waste are pencil cases, flowers, key chains, vases and so on. The activities carried out by UNRI KKN students aim to convert inorganic waste into useful and economically valuable goods. This activity was carried out at village Kulim Jaya Kempas Subdistrict,Indragiri Hilir using the Learning by Doing approach. UNRI KKN students learn by practicing directly how to process inorganic waste into flower crafts from straws using prepared tools and materials. This approach is more effective in achieving outcomes in KKN activities in Kulim jaya. The result of implementing this Integrated Real Work Lecture (KKN) activity is to provide information and innovation about managing inorganic waste into crafts so that students are able to process inorganic waste into creative crafts. This activity can also be an option to reduce waste, especially inorganic waste. Most trash comes from people living in towns and cities; most of it is biodegradable (around 75 percent) and the remainder is inorganic. Briquettes, compost, and biogas are just a few of the many products that have benefited from organic waste's widespread use. However, only a small percentage of garbage is being recycled into compost or compostable materials. Meanwhile, inorganic waste is very difficult to recycle and cannoteven be recycled naturally, so it requires a very large area of land to offset the production of this waste. Garbage is one of the problems of human life. When people's perspectives of waste, which once saw waste as worthless waste, are changed into crafts that have uses and economic value, those people's perceptions of waste shift, too.

Penelitian ini bertujuan untuk mengevaluasi potensi penggunaan cutting cement, limbah yang dihasilkan dari proses pengeboran sumur minyak, sebagai material pengisi (filler) dalam komposit kampas rem. Cutting cement berasal dari pekerjaan penyemenan sumur minyak dan mengandung senyawa berbahaya dan beracun (B3). Dalam studi ini, cutting cement dianalisis menggunakan metode X-Ray Fluorescence (XRF) untuk mengidentifikasi komposisi kimianya, yang terdiri dari 66.2% calcium oxide (CaO), 18.7% silicon dioxide (SiOâ‚‚), 5.7% metal oxide (Feâ‚‚Oâ‚ƒ), 3.4% aluminium oxide (Alâ‚‚Oâ‚ƒ), dan 2.3% magnesium oxide (MgO). Hasil analisis menunjukkan bahwa cutting cement memiliki karakteristik yang serupa dengan material pengisi komposit kampas rem lainnya, seperti cement bypass dust (CBPD). Dalam penelitian ini, formulasi komposit kampas rem dibuat dengan mencampurkan cutting cement dan barium sulfat (BaSOâ‚„) dalam berbagai fraksi volume. Proses pembuatan komposit dilakukan melalui metode metalurgi serbuk, termasuk tahapan pencampuran, penekanan panas, dan post-curing. Pengujian kekerasan menunjukkan bahwa nilai kekerasan komposit meningkat seiring dengan penurunan kandungan cutting cement dan peningkatan fraksi volume BaSOâ‚„. Nilai kekerasan tertinggi dicapai oleh sampel dengan kandungan BaSOâ‚„ tertinggi, yaitu 104.72 HRR untuk kandungan 10% cutting cement dan 27% BaSO4, sementara nilai kekerasan terendah tercatat pada sampel dengan kandungan cutting cement tertinggi, yaitu 76.66 HRR dari sampel 0% cutting cement dan 37% BaSOâ‚„. Peningkatan kekerasan ini disebabkan oleh peningkatan densitas dan kekuatan ikatan antara BaSOâ‚„ dan bahan penyusun komposit selama proses post-curing. Penelitian ini menyimpulkan bahwa cutting cement memiliki potensi besar sebagai bahan pengisi dalam komposit kampas rem, memberikan manfaat lingkungan dengan memanfaatkan limbah industri dan meningkatkan performa teknis komposit. Penggunaan cutting cement dan BaSOâ‚„ sebagai bahan pengisi dapat meningkatkan performa dan daya tahan komposit kampas rem, yang sangat penting untuk aplikasi pengereman. Penemuan ini membuka peluang untuk penelitian lebih lanjut dalam mengoptimalkan formulasi komposit kampas rem dengan bahan pengisi dari limbah industri, mendukung efisiensi dan keberlanjutan dalam industri otomotif.
