Every year, population growth in Cilacap Regency inevitably results in various impacts in various fields, including transportation and solid waste. The number of motorized vehicles in the Cilacap Regency has increased from 588,283 units in 2017 to 714,533 units in 2020. On the other hand, solid waste generation in Cilacap Regency in 2020 reached 0.22 tons per capita per year. Both activities can potentially reduce the air quality of the Cilacap Regency. One of the causes of the decline in air quality is CO2, CH4, and N2O gases, which can cause global warming. This study aims to inventory and project GHG emission loads, determine mitigation strategies and design regulations related to GHG emission reduction in the transportation and solid waste sector in Cilacap Regency. The method used to inventory GHG emissions in this research is the 2006 IPCC method with Tier 1 and Tier 2 accuracy. Then it is projected for the next ten years with a Business As Usual (BAU) scenario. To determine the selected reduction strategy using SWOT and QSPM analysis. The inventory results and projected GHG emissions in the solid waste sector in 2030 are 109.29 Gg CO2e. 4 GHG emission reduction programs in the solid waste sector could reduce up to 29.49% Gg CO2-e in 2030. Then the BAU scenario GHG emissions in the transportation sector in 2030 reached 21,417 Gg CO2e. The six proposed scenarios were able to produce a percentage of GHG reduction of 7 65% in 2030 or 1,638,409 Tons of CO2e or 1,638 Gg CO2e from 2021-to 2030 with a priority strategy for reducing GHG emissions is increasing pollution buffers by building green open space and non-motorized pathways with a reduced rate of 2%.

Clinical waste is likely to include disease-causing microorganisms, chemical wastes, and other treatments used to treat different conditions, whether solid or liquid. As a result, clinical wastes have a more significant potential for pathogenicity and toxicity than most other types of waste in all of their forms. This study aims to design a strategic decision model for managing medical waste from hospitals. The method used in this research is the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The data was collected using a questionnaire distributed to three people from various fields: hospital waste management experts, academics, and the environmental service. The results show that the preference for the best hospital waste management strategy is SOP improvement with a weight of 0.6576. Furthermore, the alternative of investing in environmentally friendly technology, 3R campaigns, and outreach to employees and visitors received a weight of about 0.4885, 0.2973, and 0.3393, respectively. This study can be a reference for research related to decision-making strategies and the field of hospital waste management.

Kebun Belimbing Ngringinrejo is the leading agrotourism in Bojonegoro Regency. COVID-19 pandemic has decreased a numeral of tourist visits which caused agrotourism income to decline, business actors, to lose their jobs, and the livelihoods of starfruit farmers to be threatened. After the COVID-19 vaccination, the re-opening of agrotourism began with the application of health protocols. Agrotourism must carry out a recovery process to return to normality. The study aims to determine the condition of sustainable livelihoods for star fruit farmers and business actors and the effect of livelihood assets on disaster recovery. This research was conducted so that agrotourism can recover immediately by optimizing high assets and improving low assets. This study used the descriptive statistic and analysis of SEM-PLS. The outcome indicated that the condition of sustainable livelihoods for starfruit farmers and business actors has a high natural, social, and physical assets. At the same time, low assets are human and financial assets. Four sustainable livelihood assets are human, natural, social, and physical, significantly influencing disaster recovery. In contrast, financial assets have no significant impact on disaster recovery. The most significant indicators for the disaster recovery process in agrotourism are developing digital solutions, and the lowest indicator is designing risk communication.

Indonesia is estimated to be one of the largest plastic-producing countries in the world. The high use of plastic will cause people to become dependent on plastic. However, dependence on plastic has a destructive impact, which makes plastic potentially harmful to human health and the environment; Greenpeace shares this concern and makes it the basis for organizing a campaign. This study aims to analyze and see how the Greenpeaceid account interacts with Twitter social media accounts through mentions and hashtags used to drive for handling plastic waste in Indonesia. This study uses qualitative research, which uses Q-DAS (Qualitative Data Analysis Software) to analyze the data; the software used is Nvivo 12 Plus. The result of this research is that Greenpeaceid uses social media as a media campaign related to the issue of plastic waste pollution. The social media used by Greenpeace is twitter; on this social media, the form of a campaign is carried out by using #Pantangplastik and #Breakfreefrompalstic, which contains various documentation related to suitable actions in managing plastic waste so that the environment is not polluted again. The existence of the #Pantangplastik Campaign will gradually reduce the use of plastic waste.

Environmental performance is significant in today's era. However, the high operational activity of the company has harmed the environment. This study examines the type of industry (TI) and the audit committee (AC) on environmental performance (EP). In addition, this paper uses firm size (FS) as an intervention. The research uses 198 units of analysis. The results show that the audit committee and firm size affected environmental performance. The type of industry and audit committee affect the firm size. Furthermore, firm size can mediate the relationship of the audit committee to environmental performance. However, the type of industry does not affect environmental performance. Therefore, firm size cannot mediate the relationship between the type of industry and environmental performance. Therefore, the company has to enhance the audit committee's role. Furthermore, the government should enforce regulations related to environmental performance, especially Law No. 32 of 2009 concerning the Protection and Management of the Environment, that all forms of environmental pollution carried out by individuals, corporations or officials can be subject to criminal sanctions. This study has limitations, only focusing on companies listed in the PROPER ranking. Future research could use all companies in many sectors for better interpretation.

Red brick is a building material that can be used as a construction material. Red bricks are made of pure clay or mixed materials. This study aimed to determine the effect of fly ash and heating temperature variations on physical properties (compressive strength, density, porosity, and absorption), chemical composition, phase structure, and morphology in brick making. The addition of fly ash by 10%, 20%, 30%, 40%, and 50% of the composition of the material is 750 grams. The red bricks were printed with a size of 5 x 5 x 5 cm3, heated at 700°C and 800°C for 2 hours, and soaked for 24 hours. Physical tests include compressive strength test, density test, porosity test, and absorption test, as well as red brick characterization, namely XRF, XRD, and SEM-EDS. Red brick with sample A10 at a temperature of 700°C has the highest compressive strength value of 3.68 Mpa, while red brick with sample A10 at a temperature of 800 °C has the highest compressive strength value of 4.17 Mpa. Characterization shows that the phases formed in red brick are quartz (SiO2), hematite (Fe2O3), and anorthite (Al2O3).
