Abstract

Cleaner production is an environmental management strategy that is preventive, integrated and continuously applied to every process. The urea fertilizer industry certainly produces waste and allows for problems or constraints in the processing process. This study aims to obtain a cleaner production strategy to increase the efficiency of urea production. This research was studied at a urea factory in Sumatera with a high production capacity of 114,584 kg/hour. The cleaner production strategy was preventive maintenance for the CO2 compressor (B/C 1.91), cleaning demister on dust recovery prilling tower (B/C 3.62), making automatic door closer (B/C 84,54), addition wire mesh on air exhaust (B/C 91,96), add a condensate drop container overall (B/C 1,51) and make repairs to existing dehumidifier in bulk storage (B/C 30,94). Determining the priority of cleaner production alternatives using the MPE method results in the highest priority net production alternative being making automatic doors closer. If all alternatives are implemented, there will be savings in energy consumption of 2.052 kWh/tonne/day. Percentage of urea and NH3 loss can be reduced up to 20% so that the prilling unit production efficiency increased by 0.24% and the savings to be obtained range from 620 thousand - 45 billion rupiah/year.

Abstract

The increasing number of fire incidents at oil and gas facilities in recent years, along with the results of fire risk assessments at the Onshore Receiving Facility (ORF) at PT XYZ, which is still ranked as medium, necessitates efforts to reduce the risk level to low. One such effort involves evaluating and developing the fire water reservoir at the ORF facility to ensure its adequacy according to standards. This research aims to enhance operational safety and environmental protection, considering the high fire risk at gas transmission facilities. The research methods include identifying fire-fighting facilities, calculating water requirements, and evaluating the capacity of existing reservoirs. Based on the analysis, a new reservoir was designed with estimated costs, locations, and alternatives to meet the fire-fighting water needs at the ORF. The fire-fighting facility at the ORF of PT XYZ, located in a densely populated area, has a water capacity of 16 m³, but the ideal requirement is 43 m³. It is recommended to build a 30 m³ ground tank or explore other alternatives, such as panel tanks, sea water, or PLN hydrant networks, to improve readiness for major fires and protect public safety around the ORF. The level of fire risk at the ORF of PT XYZ is categorized as medium (yellow). Therefore, the solution could involve building a new reservoir or a panel tank that is more resistant to the risk of cracks or leaks due to land subsidence or shifting.

Abstract

Granulated coconut sugar is a powdered coconut sugar manufactured by Purworejo farmers from the sap of the coconut. Farmers' usage of simple technologies is the primary cause of environmental problems due to poor efficiency levels and uncontrolled emission emissions. The objectives of this research were to identify the stages of the granulated coconut sugar production farmer level process, from coconut sap to farmers' granulated coconut sugar, and then analyze the total environmental impact of granulated coconut sugar production farmer level process using the Life Cycle Assessment (LCA) approach and the CML-IA Baseline calculation method. The study's scope included an inventory of "gate-to-gate" inputs and outputs, computation of each stage of the process from sap heating to granulated coconut sugar, and interpretation of the calculation results. The amount of impact created per 1 kg of farmer-produced coconut sugar was employed as the unit of function in the analysis of the consequent environmental impact. SimaPro 9.4.0.2 software was used to calculate environmental impact analysis. The GWP impact of manufacturing 1 kilogram of farmer granulated coconut sugar was 4.76E-02 kg CO2 eq, the AP impact was 9.45E-04 kg SO2 eq, and the EP impact was 2.77E-04 kg PO4 eq. The biggest GWP effect contribution indicator was the use of LPG, which was 2.89E-02 kg CO2 eq, while the largest AP and EP impact contribution indicator was the use of firewood, which was 8.16E-04 kg SO2 eq and 2.12E-04 kg PO4 eq. The improvement scenario of the granulated coconut sugar production farmer level process, namely substituting the use of firewood with rice husks, reduces 85% of the total AP impact and reduces 93% of the total EP impact.

Abstract

Banana chip processing in Lampung province uses two different frying methods, namely conventional frying and vacuum frying. The objective of this study was to compare the number of impact emissions generated from the banana chip production process in banana chip agro-industries in Lampung. This research was conducted based on the Life Cycle Assessment (LCA) method to assess the environmental impact emissions from the banana chip industry in Lampung, focusing on the impacts of Global Warming Potential (GWP), Acidification Potential (AP) and Eutrophication Potential (EP) with a function unit of 250 g/pack. Analysis using SimaPro 9.4.2 software. Analysis using the CML-IA Baseline method shows that the banana chip industry has a significant environmental impact with the largest impact by the industry, where the conventional frying method produces a GWP impact of 1.16 kg CO2 eq/package, EP 2.08E-2 kg PO4 eq/package and AP 3.6E-3 kg SO2 eq/package, while in the vacuum frying method, the GWP is 6.3E-1 kg CO2 eq/package, AP 2.3E-3 kg SO2 eq/package and EP 6,1E-3 kg PO4 eq/package. The calculated normalization data shows that the total impact of producing banana chips per package in conventional frying is 1.9E-12 person equivalent/package with the frying stage contributing 85.45% and in vacuum frying is 6.7E-13 person equivalent/package with the frying stage contributing 77.70%. The resulting emission impact value shows that the emission impact of conventional frying is higher than the emission impact of vacuum frying. However, an economic and social assessment of both frying methods needs to be done to see the sustainability index of both. Keywords: banana chips, LCA, simapro, vacuum frying

Abstract

Canning crab is one of Indonesia's marine products that has high economic value. Canning crab has an impact on the environment that needs to be studied. This research aims to identify the life cycle of the crab canning production process and examine the environmental impacts caused throughout the product life cycle. Canning crabs start with steaming, processing, and transporting (exporting) the crabs and pushing the Life Cycle Assessment (LCA) method with the CML-IA baseline approach, which focuses on the impact of Global Warming Potential (GWP), Acidification (AP), and Eutrophication (EP) with a functional unit of 0.454 kg per packaging. Life Cycle Assessment (LCA) uses the CML-IA baseline method to calculate the global impact of the crab canning industry in Makassar with a GWP impact of 13.04317 kg CO2 eq, an EP impact of 3.02x10-2 kg PO4 eq, and an AP impact of 6.78x10-2 kg SO2 eq. The most significant impact or hotspot is the impact of GWP, which has the most significant production process contribution from using crab can packaging. Improvement scenarios to reduce this impact are replacing can packaging with plastic, replacing LPG with natural gas, efficient water use, and efficient use of diesel. Simulation results show that this scenario significantly reduces environmental impacts, especially GWP impacts, with a reduction of 86%, followed by EP impacts of 88% and AP of 75%. Future research needs to review improvement scenarios related to economic calculations as well as testing the quality and durability of crab in plastic cup packaging.

Abstract

The separation of radioactive and rare earth mineral carried out in PLUTHO produces waste that still contains thorium and uranium. The resulting waste requires further processing to be environmentally friendly. The purpose of study is to reduce thorium content and radioactivity in liquid waste of PLUTHO monazite treatment process using ferro sulphate coagulant. PLUTHO Pilot Plant is one of facility that built to dissociate uranium, thorium and light rare earth from mineral of monazite. Variations of treatments applied in the research are coagulant dosage and pH. Thorium content is measured by Spectrophotometer UV-Vis method, whereas radioactivity is measured by radiation counting meter Ludlum Model 1000 Scaler. The result shows that the optimum condition of coagulation is in pH 8,0 with concentration of ferro sulphate 225 mg/L which may reduce thorium content up to 45,20 % and reduce radioactivity to 100 % out of its initial thorium content and radioactivity as much as 0,73 mg/L and 1,35 Bq/g, respectively.
