Abstract

The community of Rangdumulya Village faces challenges in processing agricultural and household waste. Sustainable waste management can overcome these issues using biopore tubes, organic fertilizers, and plastic recycling. The purpose of this community service activity is to achieve zero waste in Rangdumulya Village in the form of a clean, healthy environment and a community that is independent in managing waste. The method used consisted of three stages: preparation, socialization, and training. The biopore tube activity on January 11, 2024, with 46 participants, increased knowledge by 39.13%, and eight out of nine groups successfully created biopores tubes. The activity of making liquid organic fertilizer on January 16, 2024, with 34 participants, increased knowledge by 33.33%, and four out of five groups successfully created liquid organic fertilizer. Plastic recycling activity on January 20, 2024, with 73 participants, increased knowledge by 34.22%, and 16 out of 18 groups successfully processed plastic recycling. This indicates that the people of Rangdumulya Village understood the activities that were taught. The Rangdumulya community has successfully carried out this environmental conservation activity independently through two monitoring sessions over two months post-activity.

Abstract

 The need for clean and safe drinking water is increasing, so innovative disinfection methods are needed. This study evaluates the effectiveness of Polysilicone coated with Chitosan-Nanosilver (PCAg) as a disinfectant for drinking water treatment. The synthesis process involves the reduction of silver nitrate (AgNO3) with sodium citrate, which is then combined with chitosan in an acetic acid solution to produce a stable mixture of nanoparticles. This solution was then impregnated into polysilicone foam to create a functional filter media. The experimental results showed that the PCAg were able to effectively remove bacterial contaminants, including Escherichia coli and Total Coliform, from the distilled drinking water samples from 4 CFU/100mL to 0 CFU/100 mL, as per the quality standard of the Ministry of Health of the Republic of Indonesia number 2 of 2023. Analysis of the SEM-EDX characterization method showed an evenly distributed Chitosan-Nanosilver coating on the polysilicone surface, evidenced by the detection of 1.31% Nanosilver and an increase in carbon percentage from 40.16% to 44.98%. In addition, analysis of the FTIR characterization method showed the presence of peaks indicating alkane vibrations, aromatic rings, ester groups, and amine groups typical of chitosan. This indicates that chitosan has been coated on polysilicone. This study concludes that the coating process enables optimal interaction between chitosan, silver nanoparticles, and polysilicone, thus enhancing the antibacterial properties of the material. Thus having a significant ability to eliminate bacteria.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan efisiensi pelaksanaan kerja, mengurangi pemborosan, serta mengembangkan kompetensi karyawan melalui penerapan pendekatan Lean Thinking pada proses produksi di perusahaan industri karet. Pelaksanaan kegiatan dilakukan melalui serangkaian tahapan yang meliputi observasi lapangan, pelatihan intensif terkait prinsip-prinsip lean, pendampingan implementasi di area produksi, serta penyusunan future state process mapping sebagai panduan perbaikan berkelanjutan. Hasil pelaksanaan kegiatan menunjukkan adanya peningkatan pemahaman karyawan terhadap konsep lean, perbaikan keteraturan dan kerapian area kerja, penurunan tingkat kecacatan produk, serta berkurangnya penumpukan aliran proses yang ditandai dengan menurunnya material menganggur dan meningkatnya kelancaran aliran kerja. Penerapan sistem kerja yang lebih terstruktur juga berdampak positif terhadap peningkatan kesadaran mutu dan kedisiplinan karyawan dalam menjalankan prosedur kerja. Berdasarkan hasil tersebut, dapat disimpulkan bahwa penerapan Lean Thinking secara sistematis dan berkelanjutan mampu meningkatkan produktivitas serta kualitas proses melalui eliminasi aktivitas tidak bernilai tambah dan penguatan budaya perbaikan berkelanjutan di lingkungan perusahaan.
