Abstract

PT YZ is a palm oil industry that has a processing capacity of 60 tons of FFB/hour with its main products in the form of Palm Oil (CPO) and Kernel. The palm oil industry in addition to producing the main product in the form of CPO, also produces a large amount of waste. The waste consists of solid waste, liquid waste and gas waste. The purpose of this research is to identify the flow of materials, products, and non-products in the production process of the palm oil processing industry and waste treatment processes, identify cleaner production alternatives that can be applied to the palm oil industry and determine the priority scale of cleaner production opportunities in the palm oil processing industry. The methods used include literature study, observation, mass balance analysis, technical feasibility analysis, economics (B/C and PBP), environmental, and Exponential Comparison Method (MPE). PT YZ has handled it by reusing the waste formed as boiler fuel (solid waste) and land application (treated liquid waste), but there were still waste and loss problems. The strategy for implementing cleaner production that technically, economically and environmentally feasible were 1) Modification of the process by adding a reservoir for condensate water and oil, with B/C value = 2.5 and PBP = 0.50 years, 2) Application of good housekeeping by reducing dirt on fruit with GMP (good manufacturing practice) training, with B/C value = 1.61 and PBP = 1.63 years, 3) Application of good housekeeping by controlling or supervising the use of water by adding a water meter in each unit of process and repair of leaking pipes, with B/C value = 2.16 and PBP = 4.31 years and 4) The application of good housekeeping by reducing oil spills in the digester by repairing leaks in the digester tank and pipe, with B/C value = 1.48 and PBP 6.30 years. Based on the score obtained, it shows that the implementation of good housekeeping by reducing oil spills in the digester is the main priority. Keyword: cleaner production; MPE; palm oil

Abstract

Charcoal is a coconut derivative product produced from burning coconut shells. In this study, coconut shell charcoal was obtained from the by-product of copra processing. The processing of coconut shell charcoal produces emissions that pollute the environment, which are greenhouse gas (GHG) emissions equivalent to CO2-eq. Life cycle assessment (LCA) is a method that can assess the environmental impact of a product throughout its life cycle. Net energy calculation was carried out to determine the energy efficiency of charcoal production in the form of net energy value (NEV) and net energy ratio (NER). The LCA studied was gate-to-gate, namely from coconut shell transportation to processing into charcoal with emission function units per 1 kg of coconut shell charcoal product. The study was conducted at CV X, located in Sukabumi, West Java, Indonesia. The calculation results show that the raw material transportation stage produced 0.0626 kg CO2-eq/kg charcoal, while the pyrolysis stage produced 0.212 kg CO2-eq/kg charcoal. Energy efficiency analysis showed NEV 9,398.66 MJ and NER 1.09. Recommendations for improvement that can be given are to produce charcoal in one place with a copra factory and produce liquid smoke from the combustion of charcoal. Charcoal production in one factory with a copra factory could reduce the GHG impact by 48%, increase NEV to 12,823.19 MJ, and increase NER to 1.13. Utilization of smoke into liquid smoke increased NEV and NEV to 107,715.75 MJ and 2.03. Combining the two scenarios increased NEV and NER to 211,856.62 MJ and 2.10. Keywords: coconut shell charcoal, life cycle assessment, net energy ratio, net energy value

Abstract

Removal of Heavy Metals from Liquid Laboratory Waste Using Precipitation and Adsorption Methods. Liquid laboratory waste (such as residue of chemical oxygen demand/COD analysis) contains high concentration of heavy metals (mercury/Hg, silver/Ag and chrome/Cr) and has a high potential to pollute the environment. The liquid waste generated by laboratories is generally in small quantity, but it is extremely toxic. It is urgently in need to find out an appropriate method to reduce the problems according to the liquid waste characteristics. In this research work, precipitation and adsorption methods were evaluated to remove Hg, Ag, and Cr from liquid laboratory waste, covering determination of optimum process conditions, levels of removal and achievable treated waste quality. Results showed that a Cr removal of 97% was obtained by pH 10, and Hg and Ag removals of 97-99% were reached by pH 12. Although heavy metals removals using precipitation was very significant, but the concentration of heavy metals in the treated waste was still high (0.73-2.62 mg/L) and need for further treatment. Applying activated carbon adsorption for further treatment of the effluent reduced dissolved heavy metals to 0-0.05 mg/L, depending on the type of heavy metals as well as the type and dosing of activated carbon.

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

Current business practices are no longer relevant in the VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) environment. VUCA reflects the speed of change, uncertainty, complexity, and ambiguity in the business world. Companies need to be agile to adapt to the prevailing VUCA situations. This study aims to provide an understanding of business agility from the perspective of stakeholder needs through a model. The method used is a focus group discussion involving the relevant stakeholders, with a case study conducted in an integrated chicken meat company. The results of the study reveal that an agile ecosystem stakeholder network model consists of seven stakeholder elements: academia, business, community, government, media, financial institutions, and customers as the core element of the model. The "customer" stakeholder element is the most crucial, while the other stakeholder elements influence each other in their actions, with their ultimate goal of meeting customer needs. By placing the customer element at the core of the model, the business environment can be aligned and better outcomes can be achieved. The recommendation derived from this study is the explicit formulation of company strategies in achieving business agility. Keywords: agile, business agility, customer, model, stakeholder

Abstract

Studi kasus pengelolaan sampah rumahtangga di Wedomartani (Sleman, Yogyakarta, Daerah Istimewa) dan Banjarsari (Jakarta Selatan) memberikan perspektif alternatif untuk meminimalisasi timbunan sampah yang dikelola oleh pemerintah melalui skenario daur ulang sampah dengan mengkombinasikan aspek teknis, ekologi, ekonomi, sosial budaya, kebijakan dan kelembagaan. Tujuan dari kajian ini adalah untuk mengetahui efektivitas dan efisiensi pengelolaan sampah rumahtangga dari sumbernya di Wedomartani dan Banjarsari; 2) untuk membuat sintesis pola pengelolaan sampah berbasis komunitas; 3) untuk menguji dan mengevaluasi efektivitas dan efisiensi pola dari kedua studi kasus tersebut. Penelitian ini dilakukan dari bulan Juni 2005 sampai Agustus 2006. Pengumpulan data dilakukan melalui wawancara, observasi, dan pengambilan sampel. Analisis data dilakukan secara deskriptif meliputi analisis efektivitas biaya, analisis regresi, analisis varian dan t-test. Pengelolaan sampah berbasis masyarakat memberikan beberapa keuntungan yakni : 1) mengurangi 57 persen sampah 70 persen dari total jumlah sampah; 2) efisiensi biaya sebesar 23 persen sampai 37 persen dibandingkan pengelolaan secara konvensional; 3) peningkatan nilai ekonomi dengan penjualan barang daur ulang, pelayanan pelatihan daur ulang dan bentuk-bentuk diversifikasi yang lain; 4) menciptakan harmoni sosial antar banyak pihak. Implementasi kedua pola ini di Bogor belum dapat dilakukan secara optimal karena belum terpenuhinya prasyarat untuk mencapainya. Tingkat biaya operasional juga belum dapat dicapai secara menguntungkan.

Abstract

This research comprehensively investigated the global warming potential impact of the municipal solid waste management system using bioconversion of black soldier fly (Hermetia illucens). For this purpose, the life cycle assessment methodology was applied to evaluate the global warming potential over a 100-year horizon (GWP100) for the system used by XYZ Ltd. Depok City, identify emission sources and analyze alternative strategies to mitigate environmental impacts. Data collection for this study was conducted at XYZ Ltd. in Depok City, West Java Province, between May and June 2022. This case study focused on a cradle-to-gate analysis with a functional unit of 1 ton of municipal solid waste. The impact assessment results showed that GWP100 impact from bioconversion of municipal solid waste was 3.69E+02 kg CO2 eq. Solid waste disposed through open dumping was a dominant contributor of these emissions (2.57E+02 kg CO2 eq). The GHG emissions that were the primary source of these impacts are CH4 (2.47E+02 kg CO2 eq) and CO2 (1.19E+02 kg CO2 eq). Ultimately, the improvement scenarios recommended in this study are the pretreatment of municipal solid waste, substituting photovoltaic electricity use, choosing priority clients with the closest distance, and substituting biocomposite packaging. Implementing these measures will reduce the GWP100 impact by 56.02%. Keywords: BSF bioconversion; global warming potential; Hermetia illucens; LCA; Municipal solid waste
