Abstract

Aluminum black dross is produced by the secondary smelting process of aluminum. Aluminum black dross is classified as hazardous waste because it is reactive with water and produces substances and gases that are harmful to humans and the environment. Generally, aluminum black dross is managed by landfill method, but because it is produced in large amounts every year, the aluminum black dross needs to be utilized to reduce the impact on the environment. Aluminum black dross consists of large amounts of metal oxide and salts. The amount of metal oxide content in aluminum black dross can be used as raw material. This paper review types of processes for utilizing black dross aluminum as raw material in value-added products. aluminum black dross can be used as alumina, adsorbent, zeolite, composites, geopolymers, refractories, and fillers. By utilizing aluminum black dross waste into various products that have economic value, besides being able to protect the environment, it can also reduce environmental resource use.

Abstract

Acid mine drainage (AMD), produced when sulfide minerals are subjected to oxygen and water, is one of the major issues in mining industries. Without proper management, AMD's release to the environment would cause seriously prolonged environmental and health issues, such as increases soil acidity and reduces water quality due to extremely low pH, high sulphate concentration, and heavy metal solubility. AMD treatments are divided into two categories, i.e., active treatment, conducted by applying a chemical to the AMD to neutralize pH and precipitate heavy metals; and passive treatment, which relies on biological and biochemical processes. The active treatment may provide an immediate effect, but costly and yet sustainable; meanwhile, passive treatment takes time to establish and to generate an effect, but it is more economical, sustainable, and environmentally friendly. The wetland system is an example of passive treatment. Therefore, this review focuses on passive treatments, especially the selection of organic materials used in constructed AMD wetland treatment. Organic materials play a central role in the wetland system, i.e., to chelate metal ions, remove sulphate from the solution, increase pH, and growth media for microbes, especially sulphate reducing bacteria (SRB) and plants are grown in the system. Overall, organic materials determine the effectiveness of the wetland system to neutralize AMD passively and sustainably.

Abstract

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. (TPS B3). The Depok City Regional General Hospital (RSUD) has collaborated with third parties who have permits from the government. 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.

Abstract

Air asam tambang (AAT) merupakan salah satu masalah yang ditimbulkan akibat kegiatan pertambangan. Air asam tambang terbentuk sebagai hasil oksidasi mineral sulfida yang tersingkap ke permukaan oleh air dan oksigen. Alternatif pengelolaan AAT secara berkelanjutan dan ramah lingkungan yaitu dengan membuat konstruksi wetland. Tujuan penelitian ini adalah untuk mendapatkan jenis dan komposisi bahan organik potensial yang mampu meningkatkan kualitas AAT. Penelitian ini terdiri dari tiga tahapan penelitian yang dilakukan secara bertahap, yaitu screening jenis bahan organik, kombinasi dua jenis bahan organik yang berbeda, dan kombinasi pupuk kandang sapi dan tandan kosong kelapa sawit pada berbagai komposisi. Jenis bahan organik yang digunakan yaitu pupuk kandang sapi, pupuk kandang kambing, pupuk kandang ayam, tiga jenis pupuk kompos, tandan kosong kelapa sawit, serbuk gergajian kayu, chip kayu, cacahan eceng gondok, cocopeat, limbah segar daun kayu putih, limbah kompos daun kayu putih, limbah penyulingan sereh wangi, limbah baglog jamur, dan ampas tebu. Hasil penelitian menunjukkan bahwa terdapat beberapa jenis bahan organik yang dapat meningkatkan pH AAT. Kombinasi tandan kosong kelapa sawit dan pupuk kandang sapi dengan perbandingan 2:1 menjadi pilihan yang tepat karena mampu meningkatkan pH dan menurunkan logam berat dan sulfat terlarut serta ketersediaan bahan baku yang melimpah di alam, khususnya di Indonesia.
