As people's consumption levels increase, the plastic waste produced will also increase. It's normal if in the future it becomes a serious environmental problem. We need a technology that is able to replace plastic waste into products that have a long life so that they do not return to waste in a short time. Making paving block products from plastic waste is another way of utilizing plastic waste over a long period of time, in order to increase utilization efficiency and reduce the environmental burden on plastic waste and form innovative products into building materials. The most important problem with plastic is plastic waste which cannot be decomposed naturally. Cleaning up plastic waste takes a very long time, and also the use of plastic can hardly be regulated. Based on the results of surveys, interviews and observations conducted on the community around Kuala Village, the community's awareness of waste processing is very minimal and there are lots of piles of plastic waste which can have a negative impact on health and disrupt the preservation of environmental functions, including residential environments, forests, rice fields, and rivers. To reduce the volume of plastic waste that is not managed properly, efforts are being made to utilize plastic waste to make paving blocks in Kuala Lemang Village. to explore the potential for using plastic waste as an alternative material in making environmentally friendly and sustainable paving blocks. Plastic waste collected from the surrounding environment is processed into mixed materials in making paving blocks. This process involves chopping, mixing with conventional materials such as sand, and testing the strength of the final product. Public acceptance of plastic-based paving blocks has proven positive, especially after trials in the local environment. This research contributes to better plastic waste management and offers new economic opportunities in the construction sector, while supporting sustainable development.

The Society 5.0 era reflects the world's transition towards a society that integrates digital technology with everyday life. In this context, traditional culinary delights, such as lemang, have the potential to evolve and maintain their relevance amidst changing times. Lemang, a traditional rice-based food prepared by steaming it in bamboo sticks, has become an inseparable part of the culinary heritage of people in several Southeast Asian countries. However, with technological developments and shifts in people's consumption patterns, there is a tendency to ignore traditional culinary delights such as lemang. Therefore, it is important to implement strategies that can promote lemang so that they remain in demand in the Society 5.0 era. Integration of digital technology in the production, distribution and promotion processes of lemang can be a solution. Using social media platforms to promote the uniqueness and deliciousness of lemang, as well as bridging traditional craftsmen with a wider market through e-commerce are some ways to introduce lemang to a new generation. Additionally, innovation in recipes and presentation, without losing its traditional essence, can also be an interesting approach. By combining traditional values and innovation in the Society 5.0 era, lemang will not only survive, but will also increasingly develop and be accepted in the hearts of global society. Culinary is an important aspect of human culture that continues to develop along with the times. The Society 5.0 era, which is marked by the integration of digital technology in everyday life, provides new opportunities and challenges in preserving and improving traditional culinary culture such as lemang. Lemang is a traditional food from Indonesia, Malaysia and several other Southeast Asian countries made from sticky rice cooked in bamboo. This study aims to explain how technology and innovation can be used to improve Lemang culinary culture in the context of the Society 5.0 Era.

Lemang Tanjung Sirih mudah mengalami kerusakan akibat mikroba sehingga hanya mampu bertahan selama satu hari pada suhu ruang. Penggunaan kemasan aktif adalah salah satu upaya untuk menambah waktu simpan Lemang. Tujuan penelitian ini adalah untuk mengetahui bagaimana pengaruh pemakaian kemasan aktif silika gel terhadap kadar air dan jumlah bakteri pada Lemang. Metode penelitian yang digunakan adalah dengan merekatkan silika gel pada ujung bambu lemang dengan berat 1 gram, 3 gram dan 5 gram, kemudian disimpan pada suhu ruang selama 3, 5 dan 7 hari. Lemang yang disimpan kemudian dihitung kadar air dan jumlah mikroba. Data kemudian dianalisis dengan RAFL ( Rancangan Acak Lengkap Faktorial ) dan dilakukan uji lanjut BNT (Beda Nyata Terkecil). Hasil penelitian menunjukkan penggunaan silika gel selama penyimpanan, berpengaruh sangat nyata terhadap kadar air dan jumlah bakteri. Kadar air perlakuan silika gel 0 gram mengalami peningkatan, sedangkan perlakuan silka gel 1,3 dan 5 gram mengalami penurunan. Jumlah bakteri yang melebihi batas maksimum adalah pada perlakuan silika gel 0 gram adalah pada hari ke-3, sedangkan perlakuan silika gel 1, 3 dan 5 gram pada hari ke-5 penyimpanan. Sehingga berdasarkan hasil tersebut dapat disimpulkan bahwa penggunaan silika gel dapat menurunkan kadar air dan memperpanjang waktu simpan Lemang.

Abstract: The number of lemang entrepreneurs typical food of Bolo Village is decreasing even from lemang entrepreneurs who are still in production, their sales volume is decreasing. The main factors that cause this condition are low business management skills, no touch of technology, unattractive product displays, dirty and dusty, unhygienic, no labels and packaging so that it has an impact on reducing people's buying interest. Another problem faced by partners is that the production of lemang does not last long, as well as the low ability of partners to make jam as a complementary product from lemang. The activity methods used in community service activities include assistance in the form of changing mindsets regarding business management, training, and practice, as well as tool design as well as design/brand and packaging development. At each stage of the activity an evaluation is carried out both process evaluation and outcome evaluation so that the output of the activity can be measured. The results of this activity: 1) there is a change in mindset regarding business management; 2) the innovation of Lemang products; and 3) the existence of a label/brand design and product packaging
