The use of mercury (Hg) in the process of extracting gold from sediments can be a source of pollution for aquatic ecosystems and organisms. The aim of this study was to analyze the macrozoobenthos community structure in the Cikondang River which was affected by Hg pollution due to small-scale gold mining. Sampling was carried out by survey method at 5 sampling points along the Cikondang River from upstream to downstream. Water quality parameters measured include temperature, transparency, current velocity, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). Hg concentrations in sediments and macrozoobenthos were measured using automatic mercury analyzer. The results showed that the concentration of Hg in sediments in the Cikondang River ranged from 0.63–52.48 mg/kg and the accumulation of Hg in macrozoobenthos ranged from 0.97 to 0.98. The macrozoobenthos diversity index was 1.50-2.17 and the dominance index was 0.16-0.30. The most group of macrozoobenthos found was from the Gastropod class, followed by the Insecta and Malacostraca classes. Macrozoobenthos in the Cikondang River were only found in the downstream of the river, at Sampling Points 4 and 5 only. This showed that Hg pollution in the Cikondang river is highly toxic, caused macrozoobenthos was not found at Sampling Point 1, 2 and 3.</span></p> Kabul Fadilah, Tika Nurmala, Tri Dewi K.P. , Yayok Suryo Purnomo, Sunardi Copyright (c) 2023 Kabul Fadilah, Tika Nurmala, Tri Dewi K.P. , Yayok Suryo Purnomo, Sunardi https://creativecommons.org/licenses/by/4.0 https://ejournal.pnc.ac.id/index.php/jppl/article/view/1788 Fri, 03 Mar 2023 00:00:00 +0700 Analisis Kinerja Pengelolaan Limbah Infeksius Selama Masa Pandemi Covid-19 Studi Kasus di RSUD Kota Depok https://ejournal.pnc.ac.id/index.php/jppl/article/view/1473 <p style="font-weight: 400;">Medical waste management is one of the important things in handling the Covid-19 pandemic. Depok City is one of the areas of West Java Province in Indonesia which in the spread of Covid 19 is in the 5 (five) highest positions. The purpose of this research is the management of infectious waste before and during the emergence of the Covid-19 pandemic. This study used a qualitative method. Stages of research is the identification of performance and assessment of the performance of the management of infectious waste using the Balanced Scorecard method, identification plan management strategies using the SWOT method and prioritizing the implementation of the strategy with the method Interpretative Structural Modeling (ISM). The results showed that the infectious waste generation at the Depok City Hospital during the Covid-19 pandemic increased to 2.75 tons per year. The hospital has made efforts to reduce and sort out, but the obstacles faced during the sorting process are the limited number of Personal Protective Equipment (PPE) so that it can increase the risk of transmitting Covid-19 to officers and the absence of cold storage in the Temporary Disposal of Hazardous and Toxic Materials.

The most influential strategy that can be carried out by hospitals is to improve waste management facilities and infrastructure and strengthen SOPs with waste management parties.</p> Fara Asifa Ulfimora, Zaenal Abidin, Andes Ismayana Copyright (c) 2023 Fara Asifa Ulfimora, Zaenal Abidin, Andes Ismayana https://creativecommons.org/licenses/by/4.0 https://ejournal.pnc.ac.id/index.php/jppl/article/view/1473 Tue, 14 Mar 2023 00:00:00 +0700 Briket Olahan Limbah Organik Sebagai Solusi Affordable Alternative Energy Dalam Upaya Mencapai Sustainable Development Goals 2030 https://ejournal.pnc.ac.id/index.php/jppl/article/view/1760 <p style="font-weight: 400;"><em>The increase in people's lifestyles raises problems of energy and waste crises. The energy crisis occurred due to a rise in energy demand due to the 4.0 industrial revolution era. Meanwhile, waste problems arise as a result of public consumption. This study aimed to create a product formulation for biomass briquettes with organic waste as the primary raw material. This study used the Experimental Design Completely Randomized Design (CRD) method with four formulations. The first formulation (V<sub>1</sub>) with the composition of rice husk: dry leaves: sawdust: cardboard, respectively 10:6:0:4, V<sub>2</sub> (10:6:4:0), V<sub>3</sub> (10:6:2:2), and V<sub>4</sub> (10:2:6:2) Briquette quality testing uses four assessment indicators, namely shrinkage, ash content, combustion rate, and flame initiation time. The results showed that the composition of V<sub>2</sub> briquettes was the best formulation with a shrinkage value of 92.52%, ash content of 7.48%, combustion rate of 0.0049 g/s, and flame initiation time of 2m 48s.

Waste management activities at the Klotok TPA generate emissions from the waste pile and heavy equipment activities. This study aims to determine the air quality at the Klotok Landfill through direct measurements to obtain results with a more accurate approach. The measurement results will then be modeled with AERMOD software to determine the distribution of these pollutants to the area around the TPA. In this study, air quality measurements were carried out at three points in the Klotok TPA to determine the level of pollution that occurred. Air quality is measured directly using a High Volume Air Sampler (HVAS), Impinger, and Sound Level Meter. Air pollutant parameters measured included Nitrogen Dioxide (NO2), Total Suspended Particulate (TSP), Sulfur Dioxide (SO2), Oxidants (O3), Carbon Monoxide (CO), Lead (Pb), Non-Methane Hydrocarbons (NMHC), Particulate Matter 2.5 (PM2.5), PM10, Ammonia (NH3), and noise.

One type of zeolite that has been synthesized at room temperature is zeolite X (ZX) within a minimum of 28 days using synthetic chemicals. The purpose of this study is to explore how ZX can be formed from waste materials and NaOH technical grade solution (TGS) at room temperature for 40 days without stirring treatments. The waste materials are rice husk ash from the traditional red brick industry, aluminum beverage cans, and food packaging aluminum waste. The materials were homogeneously mixed with the NaOH TGS in such a way as to produce a mixture with a mole ratio of 7.23Na2O : 0.26Al2O3 : 1SiO2 : 280H2O, with mole ratios of Na2O/H2O and Al2O3/SiO2 that were 30% higher than the literature for ZX synthesis, respectively. The results of characterization showed that the treatment yield was ZX along with the presence of the bayerite phase, which had been formed since the 20-day observation period. The use of excess Na2O/H2O and Al2O3/SiO2 mole ratios in this study impacts the formation of bayerite first and the ability of dissolved silica to condense, thus slowing the crystallization of ZX. The result of this study led to the new finding that zeolite-bayerite composite can be synthesized directly in a simple, inexpensive, and environmentally friendly manner, where the composite materials have been reported as catalysts and adsorbents.</p> Dede Suhendar, Luthpiansyah, Budy Frasetya Taufik Qurrohman, Yusuf Rohmatulloh Copyright (c) 2023 Dede Suhendar, Luthpiansyah, Budy Frasetya Taufik Qurrohman, Yusuf Rohmatulloh https://creativecommons.org/licenses/by/4.0 https://ejournal.pnc.ac.id/index.php/jppl/article/view/1770 Tue, 04 Apr 2023 00:00:00 +0700 Efektivitas Ukuran Blok Campuran Tanah dan Hydraulic Loading Rate Pada Multi Soil Layering Guna Menurunkan Parameter Fosfat dan Surfaktan Anionik di Usaha Binatu https://ejournal.pnc.ac.id/index.php/jppl/article/view/1776 <div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>The laundry business is one of the business that produces phosphate and anionic surfactant parameters that cause eutrophication and environmental pollution.

The materials used in this study are andosol soil, rice husk charcoal and iron powder. The permeable layer uses gravel and pearlite media. The reactor is made of acrylic with a length of 50 cm, a width of 15 cm and a height of 50 cm. Multi soil layering systems successfully reduce concentrations to 98,603% for phosphate parameters and 99.99% for anionic surfactant parameters. The decrease in phosphate parameters and anionic surfactants is caused by physical and chemical adsorption processes by soil components and rice husk charcoal. The decrease in the parameters of anionic surfactants is also helped by the process of biodegradation of microbes in the soil.</p> </div> </div> </div> Tarikh Azis Ramadani, Novi Eka Mayangsari, Mitha Amelia Anjani Copyright (c) 2023 Tarikh Azis Ramadani, Novi Eka Mayangsari, Mitha Amelia Anjani https://creativecommons.org/licenses/by/4.0 https://ejournal.pnc.ac.id/index.php/jppl/article/view/1776 Tue, 04 Apr 2023 00:00:00 +0700 Pembuatan Biobriket dari Limbah Daun dan Batang Kayu Putih (Malaleuca leucadendron) Guna Memanfaatkan Limbah Hasil Pertanian di Kecamatan Jeruklegi Kabupaten Cilacap https://ejournal.pnc.ac.id/index.php/jppl/article/view/1762 <div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>Oil reserves are increasingly decreasing in line with the use of non-renewable fossil fuels.
