Abstract
Existing biodiversity has potential if it can be managed optimally and sustainably. Since January 2020, Mount Tidar has officially changed its status from an urban forest to a botanical garden. This change in status has an impact on nature conservation. The purpose of this study was to identify and determine the level of diversity in the Mount Tidar Botanical Garden (MTBG). The methods used in this study are quadratic sampling, plotting, and survey techniques. Data analysis using reference calculation of Shanon Weiner index, evenness index, Simpson dominance, and Margalef species richness index. The results showed the discovery of 121 species with a total vegetation of 5,912 individuals. Then Shanon Weiner’s diversity calculation got a medium value (H’ 2.306), evenness index at the medium level (E 0.481), Simpson dominance index with a high value (IDS 0.917), and Margalef species richness with a high value around (R 13.82). So that the value of the diversity calculation is the basis that the identification and diversity of vegetation in MTBG is at a stage of rapid development at medium to high levels. This data can be a reference for managers to make it easier to assess the Sustainable Planning and management system of MTBG conservation areas.

Abstract
Mesoplastics are plastics with a diameter between 0.5 and 2.5 cm. The purpose of this study was to characterize the properties and quantity of floating mesoplastics in the water column and at the surface. Sampling was conducted using a net with a 0.5 cm square mesh dimension at five separate places selected based on the Indonesia Standard for an hour at each location. Mesoplastics were present on average at a rate of 1.586 g/h, with an abundance of 6.05 x 10−8 kg/m3. Polyethylene, which is translucent, white, or black in color, is the most common mesoplastic polymer. The structure has cracks, white regions, and an uneven surface, which illustrates that plastic breaks down into smaller particles in river water.

Abstract
The brick industry in Indonesia has been going on for a long time. This industrial practice is generally done traditionally by using biomass in the burning process. These burning activities have the potential to produce emissions. This research was conducted in the brick industry area of Mranggen District, Demak Regency. This study identifies emission sources, raw materials, burning processes, meteorological conditions, emission characteristics, and emission distribution. The results of industrial field studies show that the raw materials used are wood and rice husks for burning. Brick burning takes 2 days and one night with a flame of 750-820°C, oven heat of 320-660°C, and wind speed of 10-20 km/hour. The meteorological conditions of the location during the burning process are air temperature 31-37°C and air humidity 56-70%. Emissions from biomass burning in the brick industry are observed to not much different from biomass burning emissions in general with special content of Si, Ba, and Cl. Preliminary simulation results show that the emission can be dispersed as far as 300 m from the source area with a concentration at a range of 250 μg/m3.

Abstract
The tofu industry in Indonesia is one of the most popular industries among Indonesians. Unfortunately, almost all tofu industries in Indonesia do not treat their wastewater correctly. Tofu liquid waste contains many pollutants as organic molecules and solids in suspension. This study aims to treat tofu liquid waste using magnetic GAC thus it is safe when when discharged into bodies of water. The adsorption process in tofu wastewater research is carried out using adsorbents. The adsorbent used is Granular Activated Carbon (GAC). The adsorbent activation process applies the wet activation method, and magnetic GAC is modified green coprecipitation method synthesis. Based on the completed research, it was found that the best allowance for turbidity test was the 15 minutes adsorption time treatment given a magnetic GAC concentration of 10 g/L with the removal efficiency of 73.92% and the best TSS concentration was adsorbtion with a magnetic GAC concentration of 7.5 g/L within 30 minutes adsorption time with a removal efficiency of 56.76%.

Abstract
About 50% of single-use plastic carrier bags are discarded after one use. There has been a gradual increase in awareness of the accumulation of end-of-life plastics and their impact on the environment, which has led to interest in the development of degradable polymers. Cassava bioplastics (polylactic acid), oxo-biodegradable, and compostable plastics are often considered a potential solution to the accumulation of plastic waste, but it was unknown whether they can be biodegraded in the natural environment. Thus, this study aims to determine the fragmentation of single-use plastic bags under various natural conditions, which are declared to have biodegradable, oxo-biodegradable, or compostable properties. Four types of degradable plastic and conventional single-use plastic carrier bags were stored in natural conditions (open-air, river water, and soil). After one month, we conducted an analysis of plastic bags, specifically examining factors such as their visual attributes, load-bearing capacity, polymer identification, and microplastic generation. Surprisingly, the compostable plastic, which was expected to demonstrate enhanced degradation when buried in soil, remained stable, as indicated by its polymer composition. This finding suggests that there is a need to improve the criteria for biodegradable plastic carrier bags to ensure that they undergo biological degradation.

Abstract
The role of community participation is needed for waste management so that there is no spike in waste accumulation in abrasion areas, especially puddles, the conceptual framework of community participation in abrasion areas and communities that are not affected by abrasion disasters. The purpose of community researchers in abrasion areas is to reduce waste collection so that the environment in the area is maintained by water diota sustainability. The method used provides community understanding to manage waste using an approach referring to existing regulations in Indonesia. As a result of this research, surveys in the area show that people do not manage their waste and often throw garbage in the water and on the roadside. The concept of community participation, duty, and responsibility leads to the reduction of recycling generation with the 3R system and reuse so the responsibility of the community who dispose of waste culture to reduce the burden of handling waste in the final waste processing.

Published: December 2023

Abstract
Sampurna Kuningan is a small and medium enterprises (SMEs) specializing in creating various brass metal handicraft products. They need to improve their efficiency in producing brass door handles within their manufacturing process. The issues mainly revolve around two tasks - dipping and refining processes. At the finishing stage, the chemical solution left from brass cleaning is improperly treated and disposed of in the sewer, wasting resources. This study’s primary objective is to evaluate the eco-efficiency index (EEI) value and propose improvement strategies to reduce the environmental impact caused by their production activities. The eco-efficiency measurement involves comparing the financial performance represented by the net value and the environmental performance measured as eco-cost. The eco-cost is calculated using a life cycle assessment through the Sima-Pro software. The results of the calculations indicate an EEI value of 2.22. The production process is both economically affordable and sustainable. However, there is a relatively high environmental impact during the finishing process. Improvement scenarios for this process include implementing water treatment or substituting finishing chemicals. Using citric acid for a brass door handle yields a significant average reduction in eco-cost, reaching approximately 50%.

Abstract
Marine pollution caused by plastic waste is a problem that occurs in many places. Plastic waste is a type of waste that is difficult to decompose, requiring a very long time to decompose. Plastic degrades into smaller particles known as microplastics, which can accumulate in seawater. Microplastics can transfer to humans and are carcinogenic. This study is a preliminary investigation of microplastic pollution in beach waters surrounded by industrial activities, tourism and fishing activities. From the analysis of microplastics from the three locations above, it can be seen that the abundance of microplastics in the area is dangerous or still at the normal threshold. Determination of the research location using purposive sampling method. Identification of microplastic particles in water samples using wet filtration to obtain microplastic samples < 5 mm using a 5 mm and 0.3 mm stainless steel mesh filter that is stacked. The abundance of microplastics in the waters of Sendang Sikucing Beach was 0.01863 particles/m³, Karang Jahe Beach was 0.26315 particles/m³, and Caruban Beach was 0.05022 particles/m³. The types of microplastics found in both waters are the same, namely fragments, fibers and films.

Published: December 2023

Abstract
Biodrying is a promising method to process municipal solid waste (MSW) while generating refuse-derived fuel (RDF) output. Recent developments in the process of generating refuse-derived fuel (RDF) have led to a renewed interest in minimal pretreatment processes. Although extensive research has been carried out, one of the most significant current discussions about generating refuse-derived fuel (RDF) using biodrying methods is that it has taken a long time to process. The biodrying method using air from the atmosphere takes 21 days to convert solid waste into RDF. As a result of this, Biodrying processes need to be accelerated by flowing hot air into the biodrying reactor. The aim of this study is to analyze the biodrying process temperature profile with a hot air aeration system. The methodological approach taken in this study is to circulate the hot air that comes from the combustion of wood charcoal. Hot air is discharged into solid waste that is inserted into the biodrying reactor. The temperature and concentration of solid wastewater are analyzed every 15 minutes. The results of this study show that the initial MSW temperature of the front reactor was 40o C and that of the rear reactor was 31o C.In the first 15 minutes until 60 minutes, the temperature shows an increase. The MSW temperature of the front reactor was 47o C, and the rear reactor was 35o C.At the 30th minute of the front reactor, it was 63o C, the rear reactor was 61o C; at the 45th minute of the front reactor, it was 81o C, the rear reactor was 73o C; and at the 60th minute of the front reactor, it was 80o C, the rear reactor was 79oC. These findings have significant implications for the understanding of how circulate the hot air aeration system works well.

Abstract
Flood is a disaster that occur since ancient times until now, and even in the future. Flood can be caused by nature, humans, or both. Constructing new dams are a good method to reduce flood and losses caused by floods, one of them is Bintang Bano Dam. The purpose of this study is to analyze the capacity of the gated spillway and ungated spillway, so that the allowable return period of discharge can be estimated through the both spillways. This research activity divided into 4 (four) stages are: the identification and data processing stage, the rainfall-runoff modeling stage, the reservoir flood routing, and the simulation of the operation of opening gates on both spillways. The gated spillway can be operated at all return periods (2 years to PMF). Ungated spillway can only overflow discharge with ≥ 100 years return period. During the return period 2 years to 50 years, no runoff occurs through the ungated spillway. For the return period of 100 years to 1000 years there is runoff through the ungated spillway without any gate openings. It is recommended for floods with a return period of 2 years to 50 years, with upstream and downstream conditions of rainfall, the gate can be closed. But for floods with 100 years to 1000 years return periods, the discharge automatically overflows through the ungated spillway cannot be opened/damaged.

Published: December 2023

Abstract
The study investigated the efficiency of generating precipitated calcium carbonate (PCC) by chemical dissolution and carbonation from extracted natural asphalt solid waste residue. This residue was then further transformed into calcium carbonate through a series of steps involving calcination at a temperature of 900 °C for 5 hours and ammonium salt dissolution. Subsequently, the calcined residue is dissolved in ammonium salt solutions (2M - NH4Cl, and NH4NO3) under a temperature condition of 60°C. Next, CO2 was injected into the solution contained a high concentration of calcium sources under a predetermined pressure. Additionally, the solution’s initial pH changed to 12 to be the ideal degree of alkalinity. A flow rate of 1 L/min of acetic acid as the extracting agent would result in the highest level of carbonation efficiency. This process yielded vaterite calcium carbonate with a purity of 99.4%, as verified through X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) tests. The vaterite of polymorphic calcium carbonate has a spherical morphology, according to studies utilizing scanning electron microscopy (SEM), confirming the morphological structure of calcium carbonate. The study could add knowledge on preparing the wastes into the high value of vaterite with low processing procedures.

Published: December 2023

Abstract
Masaro plastic refinery represents an advanced technology designed to effectively manage residual waste. This innovative approach integrates the principles of incineration and pyrolysis to obtain valuable products, including fuel and flue gas washing liquid from a wet scrubber unit. The flue gas washing liquid contains ammonia, nitrates, nitrites, and phenol compounds which still do not meet the quality standards stipulated by the Ministry of Environment and Forestry. Those compounds should be reclaimed due to their toxicity towards aquatic organisms. Fortunately, they are extensively employed in the agricultural domain such as raw material for fertilizers and pesticides. This research endeavors to conduct a comprehensive analysis of the composition of the flue gas washing liquid. The objective is to evaluate the potential application of its components as main ingredients in pesticide formulations. To augment its effectiveness, supplementary active ingredients are incorporated, derived from various plant species recognized for their efficacy in combatting pests and insects. The extraction process combines flue gas washing liquid with selected plants, such as bintaro fruit, garlic, lemongrass, neem leaves, and tobacco. From the results, this research not only addresses the environmental issue but also provides a sustainable solution to meet the agricultural sector’s demand for sustainable pesticides.

AbstractGarbage has always been a major problem in the topic of conversation due to the lack of public knowledge in processing waste. One type of waste that is often used by people everyday is plastic waste. One effort that can be used to utilize plastic waste is to use it as a concrete mixture. The purpose of utilizing plastic waste in concrete mixes is to reduce the amount of plastic waste produced by the bottled mineral water beverage factory in Pangkalpinang City, the provincial capital of the Bangka Belitung Islands Province. The method used is field observation and data collection. The results obtained from this research are how useful mineral water plastic waste is when used in concrete mixtures. Mineral water plastic can be used in various aspects of construction other than concrete mixes, so it can be considered in further research. Thus, it is hoped that this research can become a reference in the processing of plastic waste both in the field of architecture and in environmental engineering.

Abstract
Many waste products cause harmful environmental problems. Due to plastic’s versatility and high demand in a wide range of uses, its environmental effect has increased to dangerous proportions. Traditional building materials usually use a lot of energy during production, which also has a negative impact on the environment. The use of various waste materials in the construction industry is required to address these environmental challenges. Utilizing waste materials in building appears to be the most cost-effective and environmentally friendly solution to this issue. However, this study has discussed further about the current practices of the uses of waste and recycled materials in the construction industry. This study aims to review the use of these waste materials to increase the properties of concrete, an eco-friendly concrete which can reduce environmental issues. The methodology in this study is qualitative review based on the literature review from accreditation journal sites. It explains that waste materials are used as resources in the manufacturing of concrete. It is concluded that, in the future, use of plastic waste and other construction materials will serve as a source for construction material.

Published: December 2023

Abstract
More than 45.7% of Indonesia’s total energy consumption in 2021 came from the transportation sector. The transportation sector needs to improve energy efficiency and apply energy conservation measures in order to reduce energy consumption. The use of electric cars as an environmentally friendly replacement for internal combustion engine (ICE) vehicles is one effort in this direction. Using electric vehicles will reduce greenhouse gas emissions in the transportation sector; however, if fossil fuels continue to dominate the power sector, this will also lead to an increase in global GHG emissions. The power sector must employ NRE as much as possible in order to cut emissions. The energy system model, which is projected to be operational until the year 2100, was created using the LEAP and NEMO tools. Power plants are optimized for electricity delivery using the BAU and NZE scenarios. As a result of the energy system’s optimization, the usage of petroleum products will be reduced by about 778.7 million BOE in 2100, and the transportation sector’s GHG emissions will be reduced by 304.4 million tons of CO2e. By promoting energy efficiency, conservation, and the environment’s impact, the use of electric vehicles can improve Indonesia’s NZE situation in the transportation sector.
