Abstract

Permasalahan sampah semakin memburuk tiap tahun akibat pertumbuhan penduduk yang menyebabkan akumulasi   sampah dan munculnya emisi LFG (Landfill Gas) seperti gas metana, yang dapat menyebabkan pencemaran lingkungan. Untuk mengatasi ini, penelitian menggunakan model LandGEM (Landfill Gas Emission Model) di TPA Makbon dilakukan. LandGEM adalah software yang digunakan untuk mengestimasi emisi gas metana yang dihasilkan oleh TPA dengan menggunakan persamaan kinetika orde 1.Tujuannya adalah  mengukur potensi gas metana dalam penimbunan sampah di TPA Makbon. Hasil penelitian  menunjukkan bahwa rata-rata harian sampah yang dihasilkan mencapai 288 m3/hari dengan densitas rata-rata sampah di  TPA Makbon adalah 557 kg/m3. Komposisi sampah mengindikasikan 20% sampah organik (sisa makanan dan ranting). Dengan Emisi gas metana yang dihasilkan sekitar 965,3 Mg/tahun dalam skenario NSPS Applicability dan 334 Mg/tahun dalam skenario Emission Inventory. Puncak produksi gas metana diperkirakan terjadi pada 2045.

Abstract

The production of municipal solid waste is a global problem, therefore due to the large amount and environmental impacts produced, urban solid waste needs to be managed properly. The implementation of more appropriate and efficient solutions is important for sustainable development, minimizing environmental impacts and saving energy. This study aims to analyze alternative scenarios using the Waste Reduction Model (WARM) V.16 to find the best solution for solid waste management in Sorong City. Existing Scenarios, Scenario 1 (50% landfill, 25% incineration, 25% recycle), Scenario 2 (25% landfill, 50% incineration, 25% recycle) and Scenario 3 (25% landfill, 25% incineration, 50% recycle) are implemented using the WARM V.16 model. The results of this study indicate that Scenario 3 provides the best results in terms of environmental impact and energy savings (-30,443.37 MTCO2e and -784,554.96 MBTU), followed by Scenario 2 (-10,146.07 MTCO2e and -553,413.70 MBTU), Scenario 1 (-1,649.74 MTCO2e and -441,080.90 MBTU), and the Existing Scenario (35,640.31 MTCO2e and 13,725.96 MBTU).

Abstract

The rapid growth of fisheries in Sorong city has led to severe marine pollution, especially elevated Cu II concentrations that exceed water‑quality standards and threaten both ecosystems and human health. This study aimed to develop an eco‑friendly adsorbent from agricultural waste, namely citric‑acid‑activated palm‑shell powder, for the removal of Cu II from fishing‑industry effluents. The palm‑shell powder was activated by immersion in 0.1 M citric acid for 24 h, which introduced carboxyl groups, eliminated impurities, and increased porosity and surface functionality, thereby enhancing Cu II sorption capacity. A full‑factorial experimental design was employed, testing three independent variables (adsorbent mass, solution pH, and temperature) each in triplicate, with a fixed contact time of 120 min, sample volume of 50 mL, and initial adsorbent pH 6. Optimal conditions were identified as 50 mg adsorbent (capacity = 8.354 mg L⁻¹, removal efficiency = 54.14 %), pH 9 (capacity = 10.69 mg L⁻¹, efficiency = 69.28 %), and 60 °C (capacity = 7.49 mg L⁻¹, efficiency = 48.56 %). The citric‑acid‑activated palm‑shell adsorbent demonstrated significant Cu II reduction in fishing‑effluent water and presents a low‑cost, locally available, and sustainable solution for the treatment of fisheries waste streams.

Abstract

Matoa fruit is abundant in Papua and has not been optimally utilised. Matoa fruit consists of ash approximately 3.74%. The high ash and silica content make it highly suitable as a raw material for zeolite production. Zeolite can be used as a zeolite material to adsorb heavy metal Cu(II). Heavy metal pollution continues to increase with industrial growth. Heavy metals can harm human health. Innovation must continue addressing heavy metal pollution, such as Cu(II), to produce more efficient, cost-effective, and environmentally friendly technologies. This study aims to determine the ability of matoa fruit zeolite to adsorb heavy metal Cu(II). The characterization of zeolite was done using XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscope). The synthesis process involved preparing sodium aluminate and sodium silicate solutions, followed by controlled crystallisation at 105°C for 24 hours. The zeolites were tested for adsorption with the independent variable being zeolite mass, while the dependent variables were contact time of 48 hours and stirring time of 4 hours. SEM analysis confirmed the cubic morphological characteristics of matoa fruit zeolite, classifying the product as matoa fruit zeolite. The main findings of the study showed that matoa fruit zeolite can reduce Cu metal levels in sewage-polluted water with 88.85% adsorption at 0.5 g in 50 ml of test solution.
