Abstract

Farmers in Sumbersalak Village, Ledokombo, Jember Regency still depend on rice as the main commodity in their business. One important component that supports the success of rice cultivation is the availability of quality seeds. One obstacle faced in rice seed production is dormancy. One effort to improve the quality of seeds that have been stored for a long time is to give rice seeds special treatment in the hope of improving germination and early growth. The method used is participatory assistance, including dissemination of information, discussion, and direct practice of seed soaking. The activity was carried out in July 2025 at the Kenconowungu Farmer Group, involving 10 participants. The rice seeds were soaked in a 3% KNO3 solution for 24 hours. The results showed that the KNO3 treatment was effective as an invigoration technique that improved the physiological characteristics of the seeds, which had deteriorated during storage. The application of this technology was proven to increase the germination rate of local rice seeds to be faster and more uniform compared to those without treatment. Additionally, this assistance successfully improved farmers' understanding and independence in managing seeds in a practical and applicable manner.

Abstract

Garlic has limited genetic variability because the offspring are phenotypically identical to the parent plant. One approach to increase variability is mutation breeding using gamma irradiation. This study aimed to evaluate the effects of different gamma-ray doses on growth characteristics, physiological traits, chromosome number, and to determine the LD₅₀ (lethal dose 50%) in Lumbu Kuning and Lumbu Hijau garlic varieties. The experiment was conducted from May to September 2021 in Ngroto Village, Pujon District, Malang Regency, using a single-plot design with observations on individual plants. Garlic bulbs were irradiated with gamma rays at doses of 0, 2, 4, 6, 8, and 10 Gy. The t-test analysis of the M0 generation indicated that gamma irradiation significantly affected growth parameters, including leaf length and width, number of leaves, and plant height, compared to the control. The lowest mean leaf length (7.81 cm), number of leaves (3.22), and plant height (12.32 cm) were observed in the Lumbu Hijau variety at 10 Gy, while the lowest leaf width (0.37 cm) occurred in Lumbu Kuning at 8 Gy, indicating phenotypic reduction at higher doses. The highest chlorophyll content (1,091 mg/g) was recorded in Lumbu Hijau treated with 8 Gy. Gamma irradiation also induced chromosomal abnormalities, including aneuploidy with chromosome numbers such as 2n=2x−1 and 2n=2x+4. These results demonstrate that low-dose gamma irradiation can generate useful variability for garlic improvement programs.

Abstract

Abstrak Industri pengolahan tembakau merupakan salah satu sektor agribisnis yang memiliki karakteristik padat karya serta melibatkan proses kerja yang kompleks dan berisiko tinggi. Selain dituntut menghasilkan produk dengan kualitas yang konsisten, industri ini juga dihadapkan pada berbagai potensi bahaya kerja seperti paparan debu organik, kelelahan akibat pekerjaan berulang, serta risiko kebakaran yang tinggi akibat sifat bahan baku tembakau kering yang mudah terbakar. Tujuan kegiatan pengabdian masyarakat adalah untuk meningkatkan pemahaman dan penguatan implementasi budaya K3 guna mendukung efektivitas dan produktivitas proses Nazien dan Namitten. Kegiatan pengabdian masyarakat dilakukan pada 22 Februari 2026 di PTPN 1 Regional 5 Kebun Tembakau. Mitra sasaran kegiatan ini adalah kelompok buruh sortir dan kemas di gudang pengolahan PTPN 1 Regional 5 Kebun Tembakau dengan total peserta yang terlibat aktif sebanyak 20 orang. Metode pelaksanaan yang diterapkan meliputi tiga tahapan utama, yaitu penyuluhan interaktif mengenai prinsip ergonomi dan K3, pelatihan praktis (coaching) postur kerja yang aman, serta pendampingan langsung pada saat proses produksi berlangsung. Hasil kegiatan pengabdian menunjukkan capaian yang sangat signifikan baik secara kualitatif maupun kuantitatif.  Secara kuantitatif, sesi penyuluhan ini terbukti efektif dalam membangun kesadaran K3 pekerja, yang ditandai dengan lonjakan nilai post-test menjadi 88,5 (mengalami kenaikan signifikan sebesar +36,0 poin atau setara dengan +68,6%). Secara kualitatif, kesadaran pekerja terhadap pentingnya alat pelindung diri (APD) dan postur kerja yang benar meningkat tajam, serta tercipta lingkungan kerja yang jauh lebih rapi, sehat, dan aman. Dengan adanya edukasi keselamatan dan kesehatan kerja (K3) sebagai pilar efektivitas proses Nazien dan Namitten, diharapkan dapat menjadi sarana penunjang untuk meningkatkan kualitas tembakau. Kata kunci: keselamatan dan kesehatan kerja; nazien; namitten; tembakau; industri. Abstract The tobacco processing industry is a labor-intensive agribusiness sector that involves complex and high-risk work processes. In addition to being required to produce products with consistent quality, this industry faces various potential occupational hazards, such as exposure to organic dust, fatigue from repetitive work, and a high risk of fire due to the flammable nature of dried tobacco raw materials. The purpose of this community service activity is to increase understanding and strengthen the implementation of OHS culture to support the effectiveness and productivity of the Nazien and Namitten processes. The target partners for this activity are the sorting and packaging workers at the PTPN 1 Regional 5 Kebun Tembakau processing warehouse, with a total of 20 actively involved participants. The implementation method used includes three main stages: interactive counseling on ergonomics and OHS principles, practical training (coaching) on safe work postures, and direct assistance during the production process. The results of the community service activity show very significant achievements both qualitatively and quantitatively. Quantitatively, this counseling session proved effective in building workers' OSH awareness, as indicated by a surge in the post-test score to 88.5 (a significant increase of +36.0 points or equivalent to +68.6%). Qualitatively, worker awareness of the importance of personal protective equipment (PPE) and correct work posture has increased sharply,and a much tidier, healthier, and safer work environment has been created. With occupational safety and health (OHS) education as a pillar of the effectiveness of the Nazien and Namitten process, it is hoped that it will serve as a supporting tool for improving tobacco quality. Keywords: occupational safety and health; nazien; namitten; tobacco; industry.
