Dyes are becoming increasingly prevalent in wastewater, and their presence caused serious threats to the environment. One of the most widely used dyes is methylene blue which has been used in the textile industry to dye cotton, wool, and silk. As a solution to this problem, using biomass (usually considered agricultural or plantation waste) as activated carbon is an important issue. Because based on previous studies, these materials are not only abundant and affordable but also have high efficiency in removing dye. Therefore, this paper will provide a further review of the latest research on the use of activated carbon from biomass as an adsorbent for methylene blue, which includes the conversion process of biomass into activated carbon, the mechanism of methylene blue adsorption, the factors that influence adsorption process, and the characteristics of activated carbon. In addition, it also reviewed the implementation of nanotechnology on activated carbon from biomass to adsorb with methylene blue.

The production and accumulation of organic matter in the mangrove ecosystem allow this area to be rich in microbes and potentially develop as a source of various extracellular enzymes. This research aims to create effective microorganisms as bioremediation agents and determine the composition of the types of bacteria found in mangrove areas, sediments, leaf litter, stems, and mangrove plants. Sediment and vegetation were obtained as samples for being diluted and isolated, then spread onto media to get a single pure colony using Zobell 2216 method. The virgin territory formed is distinguished by characterization using macroscopic observations. It was found that the composition of bacteria isolated from the mangrove area contained 59 isolates with various visible characteristics consisting of 20 isolates of sedimentary bacteria, 27 isolates of bacteria on stems, and 12 isolates of bacteria derived from mangrove leaves. Bacterial isolates S08, B27, and D04 have the potential for the bioremediation of Hg metal. Bacterial isolates S58, B35, and D13 have potential for Pb bioremediation, while bacterial isolates S27, B35, and D12 have potential as Fe bioremediation agents.

Berenyok river is one of the water sources in Tanjung Karang, Mataram city, categorised as Class 2 for its designation. Thus, preserving the quality of water in the Berenyok river is crucial. This study aims to determine the water quality, calculate the Pollution Index (PI), and set control strategies for the Berenyok river. The study uses quantitative methods such as laboratory analysis for the water quality and PI calculation using a formula based on the Decree of the Minister of Environment No.115/2003 on determining water quality status. Meanwhile, the Strengths, Weakness, Opportunities, and Threats (SWOT) analysis generates recommendations for water pollution control strategies. The sampling locations are located in two sampling points (upstream and downstream of the Berenyok river) during bright daylight and the river's normal flow. Based on analysis results, the Berenyok river is defined as lightly polluted as the concentrations of several chemical parameters exceed the maximum limit, such as BOD, and PO3-P. It is also verified by high concentration of total coliform, namely 540,000 MPN/100mL (upstream) and 1,600,000 MPN/100mL (downstream). Thus, recommendations for water pollution control strategies are substantial for the Berenyok river.

The environmental awareness of consumer has been growing along with the increase of knowledge, education and access to information. The demand from the government, media, and community has also increasingly escalated the pressure to companies to produce environmentally friendly products. This eventually encourages greenwashing practices extensively which are unfavorable to consumers because the practice is frequently included as marketing scam. In addition, the existing environmentally-based certification is primarily oriented to the planet and profit aspects of the triple bottom lines and tends to ignore the community. Hence, this study reviews a variety of green-based certifications or sustainability indicators which has existed particularly in Indonesia and their potential for the development of convenience products, products which are consumed in high frequency since they are cheap and consumed daily. This research involves explorative analysis using open secondary data from public journalism, media releases, academic references, and official webpages. Furthermore, this research describes current green-based certifications and presents the initial concept of a sustainability indicator which involved the planet and humans concurrently as well as adopt Proper label as product labelling.

Soil is a solid mineral and organic matter from weathering rocks over the years. The current condition shows many productive lands that are of low quality. Soil quality must be a top priority in land management efforts to support the sustainability of ecology. This study proposes to soil quality index (SQI) assessment of paddy fields in Jember Regency, Indonesia, using the principal component analysis (PCA) method based on spatial data. The research procedure consists of (1) making land units, (2) soil sampling, (3) laboratory analysis, (4) principal component analysis (PCA), (5) assessment of soil quality index (SQI), and (6) Thiessen polygon analysis. The correlation results show the average correlation value < 0.5 (not significant). The soil quality is determined by three main components: total P, silt fraction, and clay fraction. The results of the soil quality analysis showed that 68,888 Ha was in the very low-quality category, and 39,948 Ha was in the low-quality category. Meanwhile, paddy fields included in the medium category are only 3,513 Ha. The addition of organic matter can improve the quality of paddy fields.

Brantas Watershed and its tributaries (approximately 14,103 km2) are essential in supplying water for About 30% of the East Java province population. Management of water resources in this watershed has become a challenging issue. The modelling processes' conformity and results to mimic the existing hydrological processes are still in question. This study aims to analyze sensitive parameters of the SWAT (Soil & Water Assessment Tool) model on the significant watershed. The input model is climate and spatial (DEM, soil layer, LULC) data. The observes the hydrological processes monthly and annually from the model result. Next, Sensitivity analysis using the SWAT-CUP tool and SUFI algorithm shows 18 sensitive parameters. The nine (9) parameters have a more than 50% sensitivity level. The four (4) correlated to the soil layer's runoff generation and water movement. Then, eight (8) parameters are related to baseflow calculation. Simulation results illustrate the strong effect of climate change (especially rainfall) on water yield and sedimentation.

The most extensive textile export product and one of the nation's cultural legacies is batik cloth. However, regarding environmental quality, West Java's growing demand for batik production results in garbage contaminating the nearby waterways. The type of dye is where the harmful properties of batik waste originate. With descriptive qualitative methodologies and the Miles and Huberman model, this study intends to explain the various types of dyes used by SMEs producing batik in the batik centre region of the City and Tasikmalaya Regency and their impact for environmental health. The findings revealed that small and medium-sized enterprises (SMEs) engaged in the batik industry in Tasikmalaya City (Cipedes) utilized synthetic dyes such as indigosol, reactive Procion and Remazol, dispersion, and direct (mostly monoazo and diazo). In the meantime, batik artisans at the Tasikmalaya Batik Center (also known as Sukapura batik in Sukaraja) work with reactive Procion and Remazol (diazo), indigosol, jolawe fruit peel (Terminalia bellirica), soga jambal bark (Peltophorum pterocarpum), and tingi as natural dyes (Ceriops condolleana). The impact of used the different azo dyes can change the level of pH extremely, also improve the level of BOD, COD, TDS, and heavy metal such as chromium hexavalent ((Cr(VI)) in the waters

Sanitary landfill is the most common type of waste processing in Indonesia because it can minimize the negative impacts caused by waste and can utilize methane gas produced from the waste decomposition process. An analysis of the population projections of Kediri and waste generation was carried out to determine the waste generation at the Klotok Landfill. This study predicts methane gas emissions produced at the Klotok Landfill based on the IPCC method. This study uses two types of data: secondary and primary data. Secondary data includes the number of residents and waste entering the landfill, while the primary data used is waste composition. A sanitary landfill is needed in order to minimize the negative impact of solid waste, one of the negative impacts caused by solid waste is the formation of methane gas. This study uses the IPCC (Intergovernmental Panel Climate Change) model to calculate methane generation in the next ten years. The results show that population significantly impacts CH4 emissions from solid waste disposal facilities. Due to the city's growing urbanization and population increase, the production of waste in Kediri is increasing. Total waste production in 2032 is 723.98 m3/day or 217,195.44 Kg/day. In contrast, the total percentage of waste that goes to the Landfill is around 55%, so the waste that goes to the landfill is around 398.19 m3/day or 119.457.49 kg/day. In addition, the increase in the amount of solid waste at the Klotok landfill also produces methane gas. Based on the amount of waste that goes to the landfill, the projected methane gas formation from the IPCC model in 2032 can reach 6.148 Mg in a day.
