Waste management is an important part to achieve green and sustainable campus. This study aims to evaluate waste management implementation in higher education. The methodology used in this study is a cross sectional with a non-probabilistic sampling. Data were collected using a well-structured evaluation instrument through an online focus group discussion, document review and evidence of implementation. The evaluation instrument consists of 10 elements: waste management policy, resource availability, waste segregation, waste collection, temporary waste storage, handling of general and hazardous waste, personal protective equipment (PPE), waste segregation awareness educational program, and evaluation on waste management. There were 15 faculties/schools/program were participated. Data was analysed using univariate analysis, radar plot representation, Box and Whiskers plot analysis. The level of waste management implementation amongst faculties /schools/program was varied between 52% to 98%. Higher education needs to evaluate waste management implementation and established a systematic environmental awareness program to achieve sustainability development goals (SDGs). The mean score ranking from highest to lowest level: personal protective equipment (5.6) to evaluation of waste management implementation (3.2). Indeed, to ensure a comprehensive general waste management, it was suggested that higher education need to build a centralized waste collection facility, a chemical waste treatment and competence personnel for handling laboratory waste.

Managing the environment is vital in guaranteeing beneficial effects to environmental action for oil and gas companies. This study aimed to analyze the programs and efforts to prevent environmental pollution by applying the Environmental Management System (EMS) in the oil and gas industry. The most popular, frequently applied EMS is the ISO 14001 and Amdal. This study used a literature review method from 26 literature and three databases: Google Scholar, ScienceDirect, and Scopus. Inclusion criteria in this study are articles related to the environmental management system in Indonesia’s oil and gas company. This study looked forward to giving insights to the actors in this industry in using the opportunity to invest while implementing efforts to prevent environmental damages and their impacts. Six underlying parts of the choice cycle have been created and utilized in using EMS: strategy/arranging, project appraisal, execution, technical thoroughness, interview, and institutional trustworthiness.

Hazardous waste may be an environmental and public health threat if not managed properly and may contribute to a regional multi-hazard when other natural disasters also exist. Hazardous and toxic waste may cause industrial disaster if its risks are not well identified and mitigated. This study aims to model the city/district-based risk assessment for each type of hazardous waste in Central Java Province for anticipating hazardous waste disasters and necessary responses. The concept of disaster is used as the method in this study, consisting of hazard, vulnerability, and capacity. The results showed that the generation of hazardous waste in Central Java Province was very large, amounting to 2,886,974.024 tons in 2021. The hazardous waste produced was sourced from 1233 types of businesses/activities in Central Java Province, with 4042 types of hazardous waste. The healthcare sector is identified as the sector that produces the most hazardous waste. Overall, the risk levels of the majority of hazardous waste types fall into the low category.

NDVI, suitability, and carrying capacity of Dieng Plateau Forests to sustain Dieng Kulon Village tourism. Biodiversitas 24: 282-289. Village tourism is a form of tourism that can support the conservation of an ecosystem. On the Dieng Plateau, Dieng Kulon is one of the tourism villages located in Banjarnegara district, Central Java, Indonesia. Despite the rapid growth of tourism in Dieng and its potential environmental consequences, information on tourism carrying capacity in Dieng is still limited. Here, this study aims to measure the suitability and carrying capacity of Dieng Kulon Village. The suitability for tourism is measured based on the Normalized Difference Vegetation Index (NDVI). Equation was used to calculate the carrying capacity. According to the findings, forest areas with a size of 23.9% and high NDVI values ranging from 0.87 to 0.91 were deemed very suitable for birdwatching and hiking activities. Agricultural land made up nearly half of the village (57.1%) with high NDVI values (ranging from 0.36-0.86) was deemed ideal for sightseeing activities. In comparison to other types of land, agricultural land had the highest carrying capacity, followed by forest land. Agricultural land can support 84.8-155.2 people per day for sightseeing activities. Forest areas are suitable for hiking and birdwatching activities. At least 51.6 to 334.9 people per day are allowed for hiking activities. Birdwatching in the forest is limited to 3.1-19.9 people per day. To conclude, carrying capacity information is very important for managing village tourism in a sustainable manner.

Establishing an in-situ conservation reserve is one of the strategic approaches to conserving an ecosystem and protecting it from immediate threats, including deforestation and land-use conversion. Kalimantan is one of the islands in Indonesia that is currently threatened by deforestation. To protect East Kalimantan diversity, mainly in Balikpapan, an in-situ conservation reserve has been established in Gunung Sepuluh Timur (GST) forest. In contrast, the information on tree diversity and how the presence of tree community within the forest can benefit the ecosystem are still limited. This research aims to assess the potential benefits and carbon storage of the GST conservation forest. The assessment method applied tree, pole, and sapling surveys combined with forest cover analysis using GIS and NDVI (Normalized Difference Vegetation Index) approaches. The GST contained 56 tree species, 25 pole species, and 16 sapling species. Diversity (H’) at tree stages was the highest (H’ = 0.759; 95%CI: 0.64-0.88) and H’ at sapling stages was the lowest (H’ = 0.719; 95%CI: 0.51-0.92). The carbon service potential of GST forest was 87.04 t C/ha on average. It was estimated that the economic benefits of GST in sequestering carbon based on the compliance market rate were equal to US$ 189,758/year.
