Data collection uses the methods of Observation, Literature, Experimentation, Documentation, Interviews, Questionnaires. The author carried out the process of using cardboard waste to make headpieces through several stages, not only that, the author also carried out experiments 3 times using different dyes. In experiment 1 using gold pilok, experiment 2 used gold pilok then sprinkled with gold glitter, then experiment 3 used wall paint coloring sprinkled with gold glitter. The author conducted a sensory test regarding the public's acceptance of headpiece products made from cardboard waste. The highest average results were obtained in experiment 3 with a total average color of 2.87 which means quite appropriate, a total average texture of 2.63 which means quite suitable, a total average design of 1.77 which is less appropriate, while the total average ease of use is 2.67, which means it is quite appropriate. So the results obtained were that as many as 30 respondents preferred product 3 with quite appropriate criteria. From the results of the products made, the coloring still needs to be improved so that they are more perfect and the designs are developed to be more varied so that they can be used as a reference for further research.

Perkembangan ilmu pengetahuan dan teknologi yang pesat di Indonesia telah mendorong pertumbuhan industri secara signifikan. Meskipun memberikan dampak positif terhadap peningkatan perekonomian masyarakat, pertumbuhan industri juga menimbulkan dampak negatif apabila tidak diiringi dengan pengelolaan lingkungan yang baik, seperti pencemaran dan kerusakan lingkungan hidup. Salah satu solusi yang dapat diterapkan dalam mengurangi dampak tersebut adalah pengelolaan limbah cair melalui sistem Instalasi Pengolahan Air Limbah (IPAL). PT. X, sebagai perusahaan BUMN, turut berkontribusi dalam pengelolaan lingkungan melalui penerapan IPAL. Fokus IPAL di PT. X meliputi perencanaan dan rekayasa instalasi, audit dan inspeksi sistem air, serta monitoring dan pengujian kualitas limbah, khususnya limbah domestik. Limbah domestik, yang berasal dari aktivitas rumah tangga seperti air bekas mandi, mencuci, dan dapur, diolah melalui metode IPAL agar dapat dimanfaatkan kembali untuk keperluan non-konsumsi, seperti penyiraman tanaman dan irigasi. Pengolahan ini menjadi langkah strategis dalam mendukung pembangunan industri yang ramah lingkungan dan berkelanjutan.

Kemuning Lor Village, Jember Regency, has significant potential in the agricultural and livestock sectors; however, the utilization of agricultural, livestock, and household waste remains suboptimal. Waste such as rice straw, animal manure, and household refuse is generally not processed effectively, leading to environmental pollution and the loss of potential economic value.

Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

Cassava is one of the strategic agricultural commodities in Indonesia, contributing significantly to national production, particularly in several major producing provinces. In addition to the challenge of declining harvested areas, cassava processing activities also generate agricultural waste that poses environmental risks. In Purwasari Village, Dramaga Subdistrict, Bogor Regency, household-scale cassava processing industries produce solid waste in the form of cassava peels, which are not optimally managed and are commonly discarded in the surrounding environment. This cassava waste has the potential to cause environmental pollution, unpleasant odours, and negative impacts on public health. One sustainable alternative for managing this cassava waste is the use of cassava peels as a raw material for composting. This study aimed to identify problems associated with cassava peel waste and to assess members of the Taruna Tani Millennial Farmer Group's interest in compost production using cassava peels. The research was conducted from December 2024 to June 2025 using a community-based assistance approach. Data was collected through interviews and questionnaires involving 20 respondents. The results showed that the main problems associated with cassava peel waste include waste accumulation, limited processing facilities, and low community awareness. Farmers’ interest in cassava peel composting was generally categorized as high, with an average score of 77%, although several indicators remained at a moderate level. Extension activities and hands-on demonstrations were proven to enhance farmers’ understanding, interest, and participation. With sustained educational support and adequate facilities, the use of cassava peel compost has strong potential to promote environmentally friendly, sustainable agricultural waste management.

Plastic waste is a form of solid waste originating from synthetic polymer materials that are difficult to decompose naturally and pose serious threats to environmental sustainability. Its accumulation continues to increase, causing pollution of soil, water, and ecosystems. In general, public attention is often limited to waste disposal and management activities without addressing preventive measures or innovative solutions at the source of the problem. This study aims to increase public awareness of plastic waste processing as an alternative approach to reducing the growing volume of plastic waste generated daily. One promising method explored in this research is the utilization of plastic waste as a raw material for producing environmentally friendly construction bricks. The study applied a simple descriptive experimental approach through direct practical activities, including the collection of plastic waste, processing and melting procedures, molding processes, and drying stages. The results demonstrate that plastic waste can be transformed into bricks with adequate physical strength and mechanical properties that comply with basic building standards. Therefore, this method has the potential to support sustainable waste management while providing alternative construction materials.
