The recent eruption of Kesongo mud volcano (MV) that occurred in 28August 2020 in Blora, Central Java was a common natural phenomenon.MV eruption occurred periodically depending on the recharge fluid systemthat interconnected to a geothermal system and hydrocarbon reservoir.During the eruption, methane and CO2 gas were emitted to theatmosphere together with rocks, muds and fluids flowing from the fractureand fault system of MV. The extruded materials could be harmful andbeneficial for the affected ecosystem. Aims: This study aimed to addressthe potential impact of the extruded mud volcano materials to theenvironment. Methodology and Results: An attempt was carried out byinvestigating gas and fluid content of every mud volcano morphology in theselected 11 areas of Kradenan, Central Java and Sidoarjo, East Java. The pristine fluids and gas of MV were sampled for chemical and toxiccompound observation. Gas composition and type was observed using gaschromatography. The result shows that methane gas content ranges from0.06 to 67.6 mol%., while the CO2 content ranges from 0.21 to 79.9 mol%.Methane gas exhibits thermogenic gas that associated with hydrocarbongeneration. Conclusion, significance and impact study: The chemicalcompound of fluids indicates high Boron (B) content above 0.5 ppm whichhas harmful effect for crops and human health, but some compounds ofCa, Na, K, Mg present as essential elements for soil nutrient. According tothe methane flux and chemical compound emitted by mud volcano, thisstudy contributes to a management practice to restore and conserve the global ecosystem.

Aims: This study aims to determine the synthesis of bagasse to form surfactants and evaluation of the performance of the sample to increase oil yield. Indonesia generates very large amounts of solid waste, without recycling or adequate management efforts to preserve the environment. Bagasse emerged as one of the most abundant biomass due to the operations of large plantations and factories. Furthermore, previous studies showed extensive uses in the fields of compost, animal feed, bioethanol energy, paper, and reinforced building materials. Methodology and Results: Lignin was extracted from bagasse to process sodium lignosulfonate surfactant (SLS surfactant). The synthesis was characterized several times, and certain examples showed significant HLB values, as a function of emulsion builder. This condition in the oil reservoir is required to reduce interface stress (IFT) and friction in the movement of particles. Another analyses involves the assessment of core flooding of specific synthetic core and crude samples. Conclusion, significance and impact of study: The results confirm the ability of surfactant bagasse to increase oil recovery, namely the HLB value of 11.6. The results also show the surfactant classification with the ability to form a middle-phase emulsion in order to increase petroleum products. Therefore, bagasse as solid waste has a performance effect on the process of increasing petroleum production.

Industrial waste that contains heavy metal can cause environmental problem because of its toxicity, persistency and accumulation level in the environment. Biosorption process is highly influenced by temperature, pH, light, contact time, and ratio of surface area. Microalgae which possess two functional groups that are able to react on metal ion in a solution can be exploited to overcome environmental pollution due to heavy metal compound. Closed cultivation system in a photobioreactor is utilized to overcome contamination and evaporation problems on open pond system. Heavy metal analysis is conducted by utilizing Atomic Absorption Spectroscopy (AAS), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscope (SEM). This article provides information on biosorption as alternative technology to overcome heavy metal in water areas with no side effects on the environment with advantages of the absence of secondary pollutants, high level of efficiency, and relatively economic compared to physic-chemical method heavy metal removal methods

Aim: The aims of this research is to determine the ability of an indigenous microbial consortium to degrade Low Density Polyethylene plastics. The plastic was cut mechanically into 1 x 1 cm2 pieces because the smaller the size of the plastic, the larger the surface area. The samples are input in an Erlenmeyer flask containing indigenous microbial consortium and fungi (20% v/v) and Stone Mineral Salt solution media (80% v/v). This research lasted 10 days with a pH of 7 controlled and temperature variations of 25, 30, 35°C. As preliminary research, the sensitivity test seeks to demonstrate that the indigenous microbial consortium and fungi are resistant or insensitive to LDPE. The degradation of LDPE plastic was analyzed using gravimetric methods, Fourier Transform Infrared, and a scanning electron microscope. Methodology and results: According to the results of gravimetric and FTIR analysis, the highest removal value was at a temperature variation of 30°C. The gravimetric analysis revealed that the weight loss in LDPE plastic was 0.0082 gr to 0,0074 gr or 9.76 %, while the FTIR analysis revealed that the intensity removal result was 6,27 %. Conclusion, significance, and impact of study: Scanning Electron Microscope (SEM) analysis revealed morphological changes on the surface of LDPE plastic samples, confirming these findings. Several factors influence the changes that occur in this study's LDPE plastic samples.

Aims: The aim of this research study is to show that the use of synthetic surfactant from bagasse is Environmentally Friendly Policies. Environmental management is an important step that needs to be taken on this immediate moment. Various human and industrial activities surely have affected the environment. Environmental management should include a number of groups from different varieties such as academics, policy makers, non-governmental organizations, corporations’ employees, government’s employees and related multidisciplinary groups. Methodology and Results: Environmental management will produce an ecological process and shapes industrial ecology which consists of four components namely; production, consumption, waste/by-products and raw materials. Bagasse as one of industrial solid wastes involved in environmental management will also produce ecological process. Bagasse which is produced from sugarcane processing can be further reprocessed into SLS surfactant that is useful for oil companies as injection fluid on reservoirs to improve oil recovery level. Conclusion, significance and impact of study: Environmental management can be applied between two industries that have mutualism symbiosis relationship through secondary production. Waste minimization can be achieved through bagasse processing. Sugarcane bagasse reprocessing into SLS surfactant is a sustainable program that supports sustainable material management effort. The action to reprocess natural waste into a valuable economical material can also alter human behavior into a more environmental friendly type of behavior.
