Abstract

This study investigates the use of nanocellulose and polyvinyl alcohol (PVA) suspension as a coating formulation on a paper substrate and its effects on the paper’s oil and water barrier properties. The PVA/nanocellulose coating suspension was prepared via a simple nanocellulose mixing procedure with various concentrations of PVA. The coating was carried out by depositing an adhesive agent and multiple layers of nanocellulose/PVA suspension on the paper surface using a bar coater. The results showed that coating up to the fourth layer decreased the opacity index and air permeability rate of the coated papers, but there was a slight increase in the air permeability at the sixth layer. The deposition of PVA/nanocellulose suspension on the paper surface also increased the water and oil barrier performance. The highest contact angle (CA) of 82° and oil kit value of 14 was obtained at the fourth layer of coating using suspension with 2 wt% of PVA content, as compared to the uncoated paper (CA 43°). It is interesting to note that coating paper using nanocellulose/PVA suspension can effectively enhance the hydrophobicity and oil barrier performances of the paper. This satisfactory results in paper properties after being coated with nanocellulose/PVA suspension can be a potential environmentally friendly material in food packaging applications.

Abstract

The batik industry in Pekalongan benefits the economy but harms the environment when untreated batik waste is discharged into rivers. The fungus Aspergillus sp. can degrade batik wastewater as an absorbent using its mycelium. Immobilizing mycelium with substrates such as loofah or oyong (Luffa cylindrical) is a practical method for waste degradation. These substrates offer unique tubular fiber structures, affordability, easy availability, environmental friendliness, high stability, and rapid adsorption ability. This study aimed to determine the decolorization of Pekalongan batik dye wastewater using Aspergillus sp. immobilized on Luffa at different incubation times and types of inoculums. This research will provide scientific information about the ability of Aspergillus sp. immobilized on Luffa to batik waste, particularly in the Pekalongan batik industry. The initial research used a dry immobilization model to study the spore and mycelium inoculum. The spore inoculum type was found to decolorize batik wastewater by 75%, which was better than the mycelium inoculum type, which achieved 37.5% decolorization. The research showed that Aspergillus sp. immobilized on Luffa without a drying process could decolorize Pekalongan batik wastewater. The most optimal decolorization results were obtained with spore inoculum treatment at an incubation time of 72 hours, achieving 99.7% decolorization. This research is supported by measurements of the dry weight of Aspergillus sp. immobilized on Luffa, pH value, DO content, TSS content, TDS content, and temperature, with respective values of 2.294-4.416 g; 5-7.14; 12-16 mg/l; 70-148 mg/l; 2013.2-3761 mg/l; and 29-31ºC.   Abstrak Industri batik di Pekalongan menguntungkan secara ekonomi bagi masyarakat, namun berdampak negatif bagi lingkungan ketika limbah batik tidak diolah dan langsung dibuang ke sungai, sehingga menyebabkan polusi. Jamur Aspergillus sp. dapat digunakan untuk mendegradasi air limbah batik karena menghasilkan enzim, dan secara non enzimatis sebagai penyerap dengan menggunakan miselium. Mengimobilisasi miselium dengan substrat, seperti buah gambas atau oyong (Luffa cylindrical), dapat menjadi metode praktis untuk degradasi limbah. Substrat ini memiliki keunggulan seperti struktur serat berbentuk tabung yang unik, harga yang terjangkau, mudah didapat, ramah lingkungan, stabilitas yang tinggi, dan kemampuan adsorpsi yang cepat. Tujuan penelitian ini adalah untuk mengetahui dekolorisasi air limbah pewarna batik Pekalongan menggunakan Aspergillus sp. yang terimobilisasi pada Luffa pada waktu inkubasi dan jenis inokulum yang berbeda. Manfaat penelitian ini untuk memberikan informasi ilmiah mengenai kemampuan jamur Aspergillus sp. terimobilisasi Luffa dalam mendekolorisasi limbah batik, khususnya industri batik di Pekalongan. Pada penelitian awal, jenis inokulum spora dan miselium dikaji dengan menggunakan model imobilisasi kering. Jenis inokulum spora ditemukan dapat mendekolorisasi air limbah batik sebesar 75%, yang lebih baik daripada jenis inokulum miselium yang mencapai 37,5% dekolorisasi. Hasil penelitian berupa perlakuan Aspergillus sp. terimobilisasi Luffa tanpa proses pengeringan yang diujicobakan dapat mendekolorisasi air limbah batik Pekalongan. Hasil dekolorisasi yang paling optimal diperoleh pada perlakuan inokulum spora dengan waktu inkubasi 72 jam, yaitu sebesar 99,7%. Penelitian ini didukung oleh pengukuran berat kering Aspergillus sp.3 terimobilisasi Luffa, nilai pH, kadar DO, kadar TSS, kadar TDS, dan nilai temperatur berturut-turut sebesar 2,294-4,416 g; 5-7,14; 12-16 mg/l; 70-148 mg/l; 2013,2-3761mg/l; dan 29-31ºC.

Abstract

The coastal area of West Kalimantan has a wealth of marine and river fishery resources that have the potential to be utilized optimally, including fishing, conservation, port activities, marine cultivation, coastal tourism, and water. Various problems in coastal areas that need to be prioritized to provide solutions include the occurrence of illegal fishing, damage to coral reef ecosystems and mangroves, coastal abrasion, not yet optimal development of ponds where utilization only reaches 40% of their potential, natural disasters which result in increased poverty and ecosystem damage, as well as the growth of corruption and injustice. The number of people living in poverty has been steadily increasing at an average rate of 6.86% over the past three years, reaching 353,350 individuals in 2023. This research aims to develop coastal areas, creating local economic development innovations to reduce poverty, unemployment, and inequality and preserve natural resources. The method developed in this study was carried out descriptively and qualitatively by developing an in-depth analysis through SWOT. The results provide solutions for improvements and innovations, which include implementing a blue economy by utilizing the modernization of fishing gear, developing a paradigm shift from land to water resources, and producing garbage filters in rivers so they do not wash away into the sea. This study will improve the quality of life economically and socially while maintaining the ecology in coastal areas.

Abstract

Increasing concern about sustainability and environmental issues caused by the massive amount of solid biomass waste in Indonesia has driven efforts to develop new products for various endues applications in energy, environment, and health sectors. This study uses coconut husk as the cellulose source to fabricate magnetic cellulose (MC) via coprecipitation with iron chloride salts. Combining cellulose with magnetite nanoparticles aims to improve the removal rate of synthetic dye as the latter provides high catalytic activity in the Fenton degradation process to eliminate persistent pollutants. The paramagnetic characteristics that MC possesses also make them quickly recovered after use. The adsorption capacity is found at 252.2 mg/g (pH 7, temperature of 30°C, the dye initial concentration of 100 ppm, and the precursor mass ratio of 1:4.8:25) for Rhodamine-B. The dye mineralization in this condition also reaches 50%, indicating that this adsorbent can be used as an efficient material to adsorb and degrade dye from an aqueous solution. This magnetic adsorbent will be of immense potential application for removing organic contaminants, particularly synthetic dyes, due to its good performance, simple separation, and ability to perform both adsorption and degradation processes simultaneously.

Abstract

Increasing greenhouse gas emissions and climate change have become urgent global challenges. Greenhouse gases, such as carbon dioxide (CO2), are primarily produced by the electricity sector, especially from burning fossil fuels. West Kalimantan Province faces specific challenges in developing its electricity sector due to the ban on bauxite exports and the increasing energy demand resulting from the expansion of smelter industries. This study aims to assess the potential reduction of CO2 emissions in West Kalimantan's electricity sector by implementing a clean energy mix, including hydropower, solar energy, and nuclear energy. A system dynamics approach is employed to model complex changes and policy impacts. The projection results indicate that developing clean energy can decrease CO2 emissions, but achieving a net-zero emission target by 2060 still requires further measures to address fossil fuel power plants.

Abstract

The increasing concentration of PM2.5, PM10, and NO2 in urban areas will impact human health. Measuring and calculating the concentration of PM2.5, PM10, and NO2 is one of the efforts to control pollution because it can obtain information on the status or category of these air pollutants. Therefore, this study aims to analyze air quality, including PM2.5, PM10, and NO2 particulates calculated based on the Air Quality Index. Pollutant measurements are carried out continuously and in real-time for 24 hours. Pollutant measurements use a continuous dichotomous aerosol chemical speciation analyzer (ACSA-14) tool placed in the BJ Habibie Science and Technology Area, Serpong, South Tangerang. Analysis of PM2.5, PM10, and NO2 concentrations were analyzed to obtain the average daily concentration during the measurement period and the ISPU method was regulated in the Regulation of the Minister of Environment and Forestry Number 14 of 2020. During the measurement period, the daily average concentrations of PM2.5, PM10, and NO2 were 40.0 μg/m3, 60.4 μg/m3, and 37.4 μg/m3, respectively, with the highest concentrations of 170.8 μg/m3, 336.0 μg/m3, 647.5 μg/m3. The moderate and unhealthy categories dominated the results of the ISPU PM2.5 analysis during the measurement period, respectively, at 55.5% and 23.0%. The good and moderate categories dominate the ISPU PM10 and NO2 analysis results, namely 38.0% and 52.2% for PM10 and 82.5% and 7.5% for NO2, respectively.
