PLTU Teluk Balikpapan with a 2 x 110 MW capacity generated fly ash and bottom ash as its waste. The waste was treated by backfilling on open land or called a landfill. The landfill was not effective because it required a large area to accommodate the waste. This research aimed to analyze waste treatment's environmental impact and identify the best scenario from three fly ash and bottom ash treatment options. The first scenario was the existing treatment that used landfill, the second was utilization into paving blocks, and the third was utilization into compost. The method in this research used Life Cycle Assessment (LCA) method. The LCA stages referred to ISO 14040 of 2006 which consists of objectives and scope, inventory analysis, impact analysis, and interpretation. The results of the analysis of the contribution of impacts on the environment with Scenario 1 obtained three impacts with the highest value, namely natural land transformation with a value of 15.8 then climate change with a value of 9.5, and particulate matter formation with a value of 6.8. Furthermore, the calculation shows that the best scenario for fly ash and bottom ash waste treatment was scenario 3: processing into compost.

Kelurahan Baru Tengah, located in Balikpapan, is a densely populated area. Still, the lack of community participation and awareness in waste management is seen from the accumulation of waste outside the waste shelter (TPS). This condition has an impact on hygiene and public health. Waste accumulation outside the waste shelter can also be caused by inadequate TPS facilities or limited TPS capacity. Therefore, research was carried out to evaluate waste containers in Kelurahan Baru Tengah. This research was conducted through field observations and waste sampling per the procedures listed in the SNI. Waste sampling was conducted eight days at three residential locations based on house conditions and two waste shelter locations to determine waste generation, composition, and characteristics. The results of this study showed that waste generation for permanent housing was 0.13 kg/person/day, waste generation for semi-permanent housing was .0.13 kg/person/day, and for non-permanent housing was 0.21 kg/person/day. The waste composition in Kelurahan Baru Tengah was dominated by organic waste at 50%, consisting of food and vegetable and fruit waste. The characteristic test showed that the waste in Kelurahan Baru Tengah had a moisture content of 90% and a C/N ratio of 17.6%.

The clean water production process must be carried out effectively without harming the environment. The Regional Drinking Water Company (PDAM) Tirta Manuntung Balikpapan City produces clean water through several Drinking Water Treatment Plants (DWTP) such as Kampung Damai and Kilometer (KM) 8. Potential negative impacts can arise from the use of chemicals, processing methods and units, as well as high-power equipment. The Life Cycle Assessment (LCA) method can be used to systematically calculate the environmental impacts of an activity's input, process, and output. This study aimed to calculate the environmental impacts due to the production process at Kampung Damai DWTP and KM 8 DWTP of Balikpapan City using the LCA method, as well as formulate strategies to reduce negative impacts. The principle of this study was to calculate impacts using the ReCiPe 2016 model (midpoint H), based on software (SimaPro), with gate-to-gate data coverage (from the intake unit to the reservoir). The study's results found that every 1 m³ of production at Kampung Damai DWTP resulted in impacts in the form of human carcinogens (0.0179 pt), freshwater ecotoxicity (0.00329 pt), and freshwater eutrophication (0.00266 pt). Meanwhile, at KM 8, DWTP resulted in human carcinogenic impacts of 0.026 pt, freshwater ecotoxicity of 0.04 pt, and marine ecotoxicity of 0.03 pt. Alternative strategy to mitigate potential environmental impacts can be implemented through the substitution of aluminum sulfate (Al2SO4) chemicals with Poly Aluminum Chloride (PAC), which reduces human carcinogenicity by 28%, freshwater ecotoxicity by 12%, and freshwater eutrophication by 4% at Kampung Damai DWTP. Furthermore, substitution of chemicals with PAC and low-power electrical equipment can reduce human carcinogenicity by 8.38%, freshwater ecotoxicity by 14.09%, and marine ecotoxicity by 12.13% at KM 8 DWTP.

Institut Teknologi Kalimantan uses a solid waste disposal system for waste management. Waste is being delivered straight to the dump (TPA) without any kind of processing or recycling. The goal of this research is to analyze greenhouse gas emissions generated from the current waste management practices at Institut Teknologi Kalimantan, as well as to evaluate emissions under Three alternative scenarios. The research method complies with IPCC 2019. Scenario 1 integrated landfilling with organic waste composting and a high recycling rate (RF: 80%). Scenario 2 involved waste incineration, organic waste composting, and a moderate recycling rate (RF: 50%). Finally, Scenario 3 focused on waste incineration combined with organic waste composting. The research findings indicate that paper waste is the largest contributor to greenhouse gas emissions in Scenario 0, accounting for 52% of the total emissions produced. Among the three scenarios analyzed, Scenario 3 generated the highest overall greenhouse gas emissions. In this scenario, waste incineration emerged as the predominant source, contributing 93% of the total emissions in Scenario 3. The types of waste contributing to greenhouse gas emissions in solid waste disposal under Scenario 0 are organic waste (food scraps), paper waste, and wood waste. Among these, paper waste produces the highest greenhouse gas emissions due to its high Degradable Organic Carbon (DOC) content. Based on the three scenarios, and assuming without considering economic aspects or control measures, waste incineration was found to produce the highest emissions compared to landfill disposal and composting.

Universitas X sebagai salah satu penyelenggara pendidikan tinggi di Kota Balikpapan turut menghasilkan Limbah Bahan Berbahaya dan Beracun (LB3) sehingga wajib melakukan pengelolaan. LB3 dihasilkan dari kegiatan laboratorium (penggunaan bahan kimia, peralatan uji berbasis elektronik) serta aktifitas operasional (penggunaan peralatan elektronik). Pengelolaan LB3 yang dilakukan Universitas X saat ini masih memiliki kekurangan, khususnya pada aspek pengurangan, pengumpulan, dan penyimpanan sehingga perlu dirumuskan strategi yang tepat. Metode Analytical Hierarchy Process (AHP) dapat digunakan untuk merumuskan suatu keputusan berdasarkan kajian secara bertingkat yang terdiri dari tujuan, kriteria, sub-kriteria, hingga alternatif solusi. Penelitian ini bertujuan mengidentifikasi jenis LB3 yang dihasilkan, mengevaluasi kondisi pengelolaan LB3, serta merancang strategi pengelolaan LB3 di Universitas X, sesuai dengan Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor 06 Tahun 2021 Terkait Tata Cara dan Persyaratan Pengelolaan Limbah. Tahapan penelitian meliputi identifikasi jenis LB3 yang dihasilkan, mengevaluasi kesesuaian kondisi eksisting, dan perumusan strategi pengelolaan LB3 berdasarkan aspek jenis kemasan, lokasi penempatan TPS LB3, serta luas TPS LB3. Perumusan strategi menggunakan metode AHP juga didukung dengan software AutoCAD dan SketchUp untuk merepresentasikan desain TPS LB3 yang sesuai dengan peraturan. Hasil penelitian mendapatkan LB3 dari kegiatan Universtas X adalah berjenis asam (865 L/Tahun), basa (810 L/Tahun), organik cair (390 L/Tahun), campuran (380 L/Tahun), an-organik cair (330 L/Tahun), lampu bekas (219 L/Tahun), kaca bekas (10 L/Tahun), dan baterai bekas (6,1 L/Tahun). Kondisi eksisting pengelolaan LB3 menunjukkan tingkat kesesuaian sebesar 49,48% yang tergolong kategori cukup. Berdasarkan metode AHP, strategi terbaik pengelolaan LB3 di Universitas X adalah skenario 1 berupa pengemasan menggunakan jerigen 20 L untuk limbah cair dan drum plastik 50 L untuk limbah padat. Saran lokasi TPS LB3 berada di antara Laboratorium Terpadu 1dan 2 dengan luasan 28 m² (panjang 7 m x lebar 4 m).
