Abstract

 Abstrak: Aktivitas pemanenan, pemuatan dan penyortiran kelapa sawit yang dilakukan secara manual beresiko untuk menyebabkan gangguan otot rangka atau muscoleskeletal disorders (MSDs). Hal ini disebabkan pekerjaan secara manual, posisi kerja berdiri dan membungkuk dilakukan secara berulang (repetitive) selama 10 jam selama 6 hari kerja sehingga tidak sesuai dengan antropometri tubuh pekerja. Analisis kuesioner Nordic Body MAP menunjukkan keluhan terbesar yang dirasakan pekerja panen pada bagian punggung (90%), pinggang (89,3%), betis kiri (90%) dan betis kanan (83,9%). Sedangkan pada pekerja pemuatan keluhan dirasakan pada bahu kiri (85%), paha kiri (82,5%) dan betis kiri (90%). Analisis postur kerja menggunakan metode OWAS juga mendukung hasil analisis kuesioner NBM dengan hasil analisa sikap bahu membungkuk dominan dilakukan sebesar 68% (kategori 2), sikap kedua lengan berada di atas bahu 53% (kategori 2) dan sikap kaki bertumpu pada kedua lutut yang ditekuk sebesar 47% (kategori 3) dengan kombinasi kode postur pemanenan 4-2-2-2 (kategori 3). Hasil analisis beban kerja pada divisi pemanenan diperoleh hasil %CVL 51% (7,25 Kkal/menit), pemuatan 55% (8,58 Kkal/menit) dan sortase 40% (6,6 Kkal/menit) dengan kategori sedang sehingga diperlukan perbaikan karena pekerja mengalami kelelahan. Analisis korelasi menggunakan metode spearman rank test menujukkan bahwa pengaruh beban kerja pada divisi panen dan sortasi mempunyai hubungan yang signifikan, dengan nilai p-value 0,00027 (OR 10 CI 95% 1,56-64,2) pada proses pemanenan dan 0,0008 (OR 11 CI 1,7-71,28) pada proses pemuatan sehingga terdapat hubungan yang signifikan (p<0,05) antara beban kerja dengan keluhan MSDs. Kata kunci: beban kerja, kelapa sawit, muscoleskeletal disorders, Nordic Body MAP, OWAS Abstract: Harvesting, loading and sorting activities in palm oil industry that conducted manually have some risks that can cause musculoskeletal disorders (MSDs). This is happened due to repetitive of manual working, standing and bending position for 10 hours and 6 working days, this activity does not match the anthropometry of worker body. Questionnaire analysis Nordic body MAP showed that the biggest complaints from harvesting workers are on their backs (90%), waist (89.3%), left calf (90%) and right calf (89.3%) and from loading workers are on rheis left shoulder (85%), left thigh (82.5%) and left calf (90%). Ergonomic risk analysis by OWAS Method also support the questioannaire analysis with result that the shoulders stooping attitude done by 68% workers (category 2), both arms above the shoulder attitude done by 53% (category 2), and leg rest to the two knee which is bent done 47% (category 3) with harvesting ergonomic combination 4-2-2-2 (category 3). Ergonomic analysis result in harvesting activity is CVL 51% (7.25 Kkal/minutes), Loading activity 55% (8.58 Kkal/minutes) and sorting activity 40% (6.6 Kkal/minutes) with medium category. Therefore, improvement is required because workers has fatigue.

Abstract

Electroplating activities produce small quantities of waste water but the level of toxicity is very dangerous because it contains heavy metals. Chemical parameters measured in this reasearch are Cr (total), Cu, and Ni. The measurement results showed the levels of chemical parameters generally exceeded the quality standard. It is necessary to do an acute toxicity test and bioconcentration factor (BCF) which is one way to monitor the negative impacts of electroplating waste water. This research was using electroplating X wastewater in Pekanbaru City and research aims are determine the LC50 value, TUa value and analyze the relationship between the quality of electroplating X waste water and its toxicity level which is supported by data on the absorption of pollutant metals in the body of test animals (BCF). An acute toxicity test was done by static method within 96 hours using a test animal of baung fish (Hemibagrus sp). The death of baung fish (Hemibagrus sp) was analyzed using the probit method. The LC50 test results were 4,8% and the TUa value was 20,833 with category III namely the level of High Acute Toxicity and BCF values of Cr (total), Cu and Ni were 0,046; 0,000102; 0,00527 with the category of low accumulation value (BCF <1). Keywords: Acute Toxicity Test, Electroplating Waste Water, Baung Fish (Hemibagrus sp), LC50, BCF.

Abstract

Changes in land cover are the most important factors causing global environmental change. This land cover change causes an increase in gases, especially CO2 gas in the atmosphere, thus becoming one of the causes of carbon gas emissions. The study site is located in Pekanbaru City which is the capital city of Riau Province with a relatively rapid rate of regional development because it is a strategic area. The purpose of this study was to analyze the land cover change of Pekanbaru City in the period 2011–2020 and analyze the value of carbon emissions resulting from changes in land cover. The method used to analyze the value of carbon emissions is the IPCC method. In 2011, the largest land cover was dry land agriculture with an area of 27,31%, plantations covering an area of 24,76%, and settlements covering an area of 24,54% of the entire Pekanbaru City. In 2020, the area of dry land agriculture decreased drastically to 0%, while plantations experienced a fairly high increase in area to 36,07%, and settlements also experienced an increase in area to 51,32%. As a result of land cover changes in Pekanbaru City, for 10 years the estimated value of carbon sequestration is higher than the value of carbon emissions. The carbon absorption value of Pekanbaru City in the 2011–2020 period is 4,879,901,455 tons CO2-eq, while the carbon emission value of Pekanbaru City in the 2011–2020 period is 710,370,804 tons CO2-eq. The highest carbon stock value for each land cover class in Pekanbaru City for the 2011–2020 period, was in 2020 with a carbon stock value of 2,413,271 tons/year.Keywords: carbon absorption, carbon dioxide, carbon emissions, land cover change, Pekanbaru city.

Abstract

X Communal Wastewater Treatment Plant (WWTP) in Pekanbaru City is one of the solutions in processing domestic waste water so that it is safe before being discharged into waters. However, the WWTP effluent test results showed the value of COD, TSS, and Ammonia that exceed the quality standard. So there is a need for WET (Whole Effluent Toxicity) testing which is one way to monitor the performance of Wastewater Treatment Plant. This research aims to determine the value of LC50, TUa and analyze the connection between the quality of waste water and the level of toxicity in waste water. Acute toxicity tests were performed by static methods within 96 hours using Daphnia Magna test animals. Mortality of Daphnia magna were analyzed using Probit Method. The value of LC50 is 5,719% and TUa value is 17,486 with category III that means wastewater is on High Acute Toxicity. Measured COD, TSS, Ammonia, and Oil & Fat parameters affect the mortality of test animals, where the value of each of these parameters is directly proportional to the death rate of Daphnia magna. Keywords: Toxicity Test, Communal WWTP, Daphnia magna, WET, LC50.

Abstract

Microplastics are one of the major threats to ecosystems in rivers. Microplastic is the smallest part of plastic measuring <5 mm which if it enters the environment it will accumulate in the waters and is not easily removed because of its persistent nature. The abundance of microplastics is strongly influenced by their activities and pollutant sources. The Sibam River is a tributary that empties into the Siak River. The high activity along the river and the presence of settlements are thought to be the distribution route for microplastics to the river. The purpose of this study was to determine the abundance and types of microplastics in the Sibam River, Pekanbaru Riau. The abundance of microplastics obtained was based on 3 segments, which ranged from 4.444-11,555 particles/kg dry sediment. The types of microplastics found in this study were fiber (15.38%), film (40.38%), and fragments (44.24%).Keywords: microplasty, abundance, sediment, Sibam River
