Abstract

Batik is a traditional process of repeatedly applying wax and dye on fabric to produce intricate and colourful patterns. Occupational safety and health issues arise among workers due to improper positioning during the mencanting process or exposure to risk factors in the workplace. This community service aims to implement workplace climate measurement using the Wet Bulb Globe Temperature (WBGT) index, work fatigue using a reaction timer test, light intensity with a lux meter in the mencanting area, musculoskeletal pain using the Nordic Body Map (NBM) questionnaire, as well as promoting occupational safety and health materials to 8 participants whom are workers at Small and Medium-sized Enterprise (UKM) Sanggar Batik Cirebon. The measurement results showed the average (WBGT) workplace climate index was 28.13 °C; the average work fatigue was 531.48 milliseconds; the average range of light intensity was 45.20 Lux - 85.33 Lux; and the average NBM score was 47.13. During the delivery of the occupational safety and health promotion materials, the participants appeared enthusiastic and motivated.  Keywords:  Ergonomic, light intensity, musculoskeletal, work fatigue.

Abstract

Particulate matter (PM) is an air pollutant that has an impact on public health, especially in an urban area. The objective of this study was to analyze the personal concentration of PM2.5 and its composition among police working in the roadside area in Jakarta. PM measurement has done to the policeman that controlled traffic on four near highway locations in Jakarta. Sioutas impactor, Leland Legacy personal pump, and quartz fiber filter were chosen to measure the fine particles. Each PM was measured for 8-hour period. PM concentration was analyzed by the gravimetric method while tracing element and black carbon in PM0.25 by energy dispersive X-ray fluorescence (EDXRF) and EEL Smoke Stain Reflectometer. As a result, near highway PM2.5 concentration in Jakarta during weekdays and weekends measurement are 92.18 ± 10.66 μg/m3, and 78.09 ± 11.61 μg/m3. S, K, Fe, Ca, Zn, and Pb are major elements found in all locations. The black carbon concentration in all location was 17 ± 5.7 μg/m3. A high concentration of fine particles, a traffic-related trace element in PM0.25, and black carbon are showed that traffic-related source is the major contributor to a high level of fine particulate matter at near highway locations in Jakarta. The weekday's concentration of PM2.5 and PM0.25 among Jakarta Policemen was higher than in the weekend concentration. A particle with size of less than 0.25 µm dominated the fine particles concentration. Further researcher is expected to see the difference in the effects of traffic-related particulate matter exposure between traffic policeman and police who work at office.

Abstract

Keluhan muskuloskeletal adalah beragam gejala yang berkaitan dengan gangguan pada sistem muskuloskeletal, seperti nyeri, kekakuan, inflamasi, pembengkakan, serta gangguan pada fungsi atau gerakan tubuh. Keluhan ini dapat mencakup berbagai kondisi seperti nyeri punggung, nyeri pada sendi atau otot, kelemahan otot, serta keterbatasan dalam mobilitas dan aktivitas fisik. Penelitian ini bertujuan untuk mengetahui hubungan antara postur kerja, masa kerja, dan usia dengan keluhan muskuloskeletal pada pekerja bagian perawatan di PT X. Metode penelitian yang digunakan adalah survei cross-sectional dengan pengumpulan data melalui kuesioner yang diisi oleh 31 responden. Analisis data dilakukan menggunakan uji alternatif Fisher untuk mengidentifikasi korelasi antara variabel postur kerja, masa kerja, dan usia dengan keluhan muskuloskeletal. Hasil penelitian menunjukkan bahwa 25 responden (80,6%) mengalami keluhan ringan sedangkan 6 responden (19,4%) mengalami keluhan berat. Hasil uji statistik menunjukkan postur kerja tidak memiliki hubungan signifikan dengan keluhan muskuloskeletal (p-value = 0,654) sedangkan masa kerja (p-value = 0,004) dan usia (p-value = 0,002) masing-masing memiliki korelasi signifikan dengan keluhan muskuloskeletal. Berdasarkan temuan ini, perusahaan disarankan untuk memantau risiko ergonomi secara berkala terhadap seluruh pekerja bagian perawatan, mengadakan program senam sehat secara rutin seminggu sekali, menyelenggarakan pelatihan ergonomi di tempat kerja, menyesuaikan ulang jadwal kerja dan istirahat sesuai dengan kebutuhan pekerja, serta mengimplementasikan program peregangan tubuh selama jam kerja.

Abstract

This study investigates the role of anthraquinone (AQ) in decomposing coconut husk waste, specifically collected from Banten, to produce pure α-cellulose pulp. The process used sodium hydroxide (NaOH) at 10%, 15%, and 20% concentrations, with 0.1 g of AQ added as a catalyst, and a waste-to-liquid ratio of 1:8 throughout. The goal is to accelerate lignin degradation while protecting cellulose in the material, thereby yielding higher-quality pulp. The Banten coconut husk analysis showed an α-cellulose content of 30.38%. Higher NaOH concentrations reduced pulp yield but increased lignin removal, indicated by lower kappa numbers. AQ addition enhanced lignin removal and preserved cellulose compared to the absence of AQ. The optimal outcome was achieved with 15% NaOH and 0.1 g AQ, balancing lignin removal and cellulose preservation. These findings indicate that anthraquinone can support sustainable pulp production from agricultural waste. Copyright © 2026 by Authors, Published by BCREC Publishing Group.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan mengimplementasikan Keselamatan dan Kesehatan Kerja (K3) di PT Tritama Wirakarsa, perusahaan yang bergerak di bidang formulasi dan repacking pestisida. Permasalahan utama yang diidentifikasi adalah belum optimalnya kondisi lingkungan kerja fisik dan tingginya tingkat kelelahan pekerja. Metode pelaksanaan meliputi pengukuran kuantitatif terhadap parameter lingkungan kerja (pencahayaan, iklim kerja, kebisingan, dan paparan debu) sesuai standar SNI serta penilaian kelelahan kerja menggunakan Reaction Timer dan Fatigue Assessment Scale (FAS). Hasil evaluasi menunjukkan bahwa 6 dari 8 titik pengukuran pencahayaan tidak memenuhi standar Permenaker No. 5 Tahun 2018, dengan intensitas terendah 84,5 lux. Suhu dan kelembaban di Plant 2 melebihi batas nyaman (suhu 30,1-31,3°C; kelembaban 60,6-63,2%), dan konsentrasi respirable dust (3,5 mg/m³). Pengukuran kelelahan objektif mengungkapkan 65% pekerja mengalami kelelahan berat sebelum bekerja. Solusi yang direkomendasikan meliputi penambahan dan perbaikan sistem pencahayaan, instalasi ventilasi yang memadai, penerapan alat pelindung diri yang tepat, serta pengaturan beban kerja. Kegiatan PkM ini sangat penting karena memberikan rekomendasi berbasis data untuk meningkatkan kondisi kerja, mengurangi risiko kesehatan, dan mendukung produktivitas berkelanjutan di perusahaan.

Abstract

Aim: This study evaluated air quality, worker exposure, and health risks at a 3R Integrated Waste Processing Facility in Banyumas Regency, Indonesia, where waste is combusted for extended periods. Methodology and results: Over five consecutive days, concentrations of PM2.5, PM10, CO2, CO, and respirable dust were measured during morning and afternoon shifts. Results revealed persistently hazardous particulate matter levels: PM2.5 exceeded World Health Organization (WHO) limits by 10–90 times, and PM10 by 5–44 times, with no significant difference between sampling periods (p > 0.05). Respirable dust and CO remained within safe thresholds, while CO2 was consistently elevated during morning startup operations. Risk Quotient (RQ) analysis identified CO2 as the only pollutant above the safety threshold (RQ = 1.184), correlating with worker-reported symptoms such as dizziness, fatigue, and difficulty concentrating. Intake calculations confirmed high chronic health risks, particularly for respiratory and cardiovascular disease. Conclusion, Significance, and Impact: Immediate interventions are required, including improved combustion efficiency, local exhaust ventilation, strict use of personal protective equipment, and regular worker health monitoring. Long-term strategies should focus on regulatory reform, advanced emission control technologies, and transitioning toward sustainable waste management through recycling, composting, and circular economy practices. These actions align with United Nations Sustainable Development Goals for health, sustainable cities, and climate action.
