Abstract

Pekerjaan pemolesan logam chrome merupakan aktivitas yang berulang dan memerlukan postur tubuh yang kurang ergonomis, sehingga berisiko tinggi menimbulkan gangguan musculoskeletal disorders (MSDs). Penelitian ini bertujuan untuk mengevaluasi postur kerja pekerja divisi pemolesan logam di CV. Jaya Makmur menggunakan metode Rapid Upper Limb Assessment (RULA), serta merancang alat bantu berupa meja kerja ergonomis untuk menurunkan tingkat risiko tersebut. Data dikumpulkan dari data yang sudah ada di perusahaan dan melalui observasi langsung terhadap tiga pekerja dan dianalisis berdasarkan pengukuran sudut tubuh saat bekerja. Hasil penilaian menunjukkan bahwa skor RULA berada pada tingkat 6, yang mengindikasikan perlunya intervensi segera terhadap kondisi kerja. Keluhan pekerja yang dominan dirasakan meliputi nyeri pada punggung dan leher. Sebagai solusi, desain meja kerja ergonomis dengan menyesuaikan postur tubuh pekerja, sehingga diharapkan dapat memperbaiki postur kerja, mengurangi keluhan MSDs, serta meningkatkan kenyamanan dan produktivitas kerja. Chrome metal polishing is a repetitive activity and requires a less ergonomic posture, thus having a high risk of causing musculoskeletal disorders (MSDs). This study aims to evaluate the working posture of workers in the metal polishing division at CV. Jaya Makmur is using the Rapid Upper Limb Assessment (RULA) method and designing an ergonomic workbench to reduce risk. Data was collected from existing company data and through direct observation of three workers and analyzed based on measurements of body angles while working. The assessment results showed that the RULA score was at level 6, indicating the need for immediate intervention to address working conditions. The dominant complaints from workers included back and neck pain. As a solution, an ergonomic workbench design that adjusts to the workers' posture is expected to improve work posture, reduce MSD complaints, and increase work comfort and productivity.

Abstract

Penjahit UMKM memiliki risiko tinggi mengalami gangguan muskuloskeletal (MSD) akibat postur kerja yang tidak ergonomis dan aktivitas berulang yang dilakukan dalam durasi lama. Studi ini bertujuan untuk menilai postur kerja dan tingkat risiko MSD pada penjahit UMKM menggunakan metode Rapid Entire Body Assessment (REBA) dan Rapid Upper Limb Assessment (RULA. Penilaian dilakukan melalui observasi langsung, dokumentasi postur kerja, dan pengukuran sudut tubuh selama aktivitas menjahit. Hasil analisis RULA menunjukkan tingkat risiko sedang hingga tinggi yang memerlukan perbaikan postur kerja, sedangkan hasil REBA menunjukkan risiko sedang hingga tinggi yang memerlukan tindakan korektif. Postur kerja berisiko tinggi terutama terjadi pada posisi duduk membungkuk, leher tertunduk, dan penggunaan lengan statis yang berkepanjangan. Oleh karena itu, perbaikan ergonomis diperlukan berupa penyesuaian fasilitas kerja dan edukasi tentang postur kerja yang benar untuk mengurangi risiko MSD pada penjahit UMKM. MSME tailors have a high risk of experiencing musculoskeletal disorders (MSDs) due to non-ergonomic work postures and repetitive activities carried out for long durations. This study aims to assess the work posture and MSD risk level in MSME tailors using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods. The assessment was carried out through direct observation, documentation of work postures, and measurement of body angles during sewing activities. The results of the RULA analysis showed a moderate to high risk level that requires work posture improvement, while the results of the REBA showed a moderate to high risk that requires corrective action. High-risk work postures mainly occur in hunched sitting positions, bowed necks, and prolonged static arm use. Therefore, ergonomic improvements are needed in the form of adjustments to work facilities and education about correct work postures to reduce the risk of MSDs in MSME tailors.

Abstract

Pemurnian etanol dari campuran alkohol dan air merupakan tahapan penting dalam produksi bioetanol, terutama untuk meningkatkan kualitas produk akhir. Penelitian ini bertujuan untuk mengevaluasi kinerja pemisahan etanol melalui kombinasi proses distilasi menggunakan kolom berkemasan dan adsorpsi menggunakan silika gel. Variasi rasio refluks distilasi sebesar 1,36; 2,86; dan 3,00 mL/min serta temperatur adsorpsi 80°C, 90°C, 100°C, dan 110°C digunakan untuk menentukan kondisi operasi optimum. Hasil penelitian menunjukkan bahwa peningkatan rasio refluks meningkatkan konsentrasi etanol hasil distilasi, dengan nilai tertinggi diperoleh pada rasio refluks 3,00 mL/min. Pada tahap adsorpsi, temperatur 80°C menghasilkan konsentrasi etanol tertinggi dan persentase penyerapan air terbesar. Selain itu, penggunaan pelarut octanol memberikan kinerja pemisahan yang lebih baik dibandingkan dodecanol. Purification of ethanol from alcohol–water mixtures is an essential step in bioethanol production to improve the quality of the final product. This study aims to evaluate the performance of ethanol separation using a combination of packed column distillation and adsorption with silica gel. Variations in distillation reflux ratios of 1.36, 2.86, and 3.00 mL/min, as well as adsorption temperatures of 80°C, 90°C, 100°C, and 110°C, were applied to determine the optimum operating conditions. The results indicate that increasing the reflux ratio enhances the ethanol concentration in the distillate, with the highest value obtained at a reflux ratio of 3.00 mL/min. In the adsorption stage, an operating temperature of 80°C produced the highest ethanol concentration and the greatest water adsorption efficiency. In addition, the use of octanol as a solvent resulted in better separation performance compared to dodecanol.

Abstract

Pencemaran udara merupakan salah satu permasalahan lingkungan yang berdampak luas terhadap kesehatan manusia, ekosistem, dan perubahan iklim. Pencemaran ini disebabkan oleh berbagai polutan seperti sulfur dioksida (SO2) dan nitrogen dioksida (NO2) yang dominan disebabkan oleh aktivitas industri dan pembakaran bahan bakar kendaraan bermotor. Oleh karena itu perlu dilakukan pemantauan kualitas udara agar bisa menentukan strategi dalam menjaga stabilitas kualitas udara. Penelitian ini untuk mengetahui tingkat kualitas udara di Kabupaten Mojokerto dan mekanisme pemantauan kualitas udara dengan metode passive sampler. Pemantauan dilakukan di 4 titik yang mewakili kondisi wilayah perkantoran, pemukiman, industri, dan transportasi. Titik pemantauan kualitas udara berlokasi di kawasan pemukiman, perkantoran, industri dan padat tranasportasi Kabupaten Mojokerto. Hasil dari pemantauan kualitas udara adalah rata-rata konsentrasi SO2 dan NO2 Kab. Mojokerto masih berada dibawah baku mutu sesuai dengan Permen LHK no 27 Tahun 2021. Air pollution is one of the environmental issues that has wide-ranging impacts on human health, ecosystems, and climate change. This pollution is caused by various pollutants such as sulfur dioxide (SO2) and nitrogen dioxide (NO2), which are predominantly generated by industrial activities and motor vehicle fuel combustion. Therefore, air quality monitoring is necessary to determine strategies for maintaining air quality stability. This research aims to determine the air quality level in Mojokerto Regency, the air quality monitoring mechanism using the passive sampler method, and the efforts undertaken to maintain air quality stability in Mojokerto Regency. Monitoring was conducted at four locations representing office areas, residential areas, industrial areas, and transportation zones. The air quality monitoring points were in residential areas, office areas, and dense transportation areas in Mojokerto Regency. The results of the air quality monitoring showed that the average concentrations of SO2 and NO2 in Mojokerto Regency were still below the quality standards stipulated by the Minister of Environment and Forestry Regulation No. 27 of 2021.
