Abstract

Soeharto Forest Park is a forest area located in East Kalimantan, Indonesia. Soeharto Forest Park has an area of about 61,840 hectares and is one of the critical forest areas in Indonesia. Soeharto Forest Park primarily serves as a conservation area and nature preservation. It contains high biodiversity, including various species of flora and fauna that are protected. The research methods involve field surveys, structured interviews, and secondary data analysis. Data was collected to understand community land tenure, including tenure rights, land use, and agricultural practices. In addition, deforestation impacts are identified through mapping land cover change and vegetation density analysis. It is just that over time, the connection of the surrounding community with Soeharto Forest Park is very high. Many people use the Forest Park area to become open land. This lasted from 1957 until 2022. The total land area of Soeharto Forest Park that has been opened is 335,994 m2 or 33,6 hectares. Many communities on the outskirts of Soeharto Forest Park that cleared land and used it as settlements, plantations, and rice fields from 1957 to 2022 highlights the deforestation in land use around the area over a long period. These changes reflect social, economic, and policy dynamics that affect local communities and the surrounding environment.

Abstract

Watersheds have an important role in managing rainwater. A good watershed can provide sufficient water for the community in the dry season and does not cause flooding in the rainy season. Therefore, watershed preservation is necessary as an effort to maintain or improve its function. Rehabilitation is an effort to restore, maintain, and improve the watershed function. In this study, rehabilitation was carried out in an area of 285 ha which cuts two watersheds, Langkapa and Poleang watershed. The success of this rehabilitation can be reviewed through the runoff coefficient before and after rehabilitation. The runoff coefficient is a value that expresses the percentage of rainwater that turns into surface runoff water. That value can be an indicator of the watershed quality. The determination of the runoff coefficient in this study used the Cook Method which considers four physical parameters, land cover, slope, soil infiltration, and surface deposit/flow density. The results showed the runoff coefficient decreased after the rehabilitation from 68.54% to 65.85% which means the rehabilitation has improved the watershed quality. But those change is not significant because the rehabilitation location actually is not the priority land (critical land) that needs rehabilitation.

Abstract

Anammox activity of water and sediment taken from marine ecosistem around Semarang were investigated in anammox media agar and batch reactor. Effect of increasing salinities (3% to 5%, 7% and 9%) and decreasing salinities (3% to 2%, 1% and 0%) were  investigated. Water and sediment taken from marine ecosistem around Semarang city showed a positive result. Increasing salinity up to 9% will have a positive influence on the activity of anammox bacteria. Whereas, the decrease in salinity will negatively affect anammox bacteria. The ratio of ammonium:nitrite for anammox process ranges from 0.89 to 1.22 and ammonium removal rate varies from 0.08 to 0.59 mg-N/liter hour.

Abstract

Plastic waste has emerged as an important environmental concern. Among the various types of plastic waste, such as Polyethylene Terephthalate (PET) and Polypropylene (PP), these two contribute the most to the overall plastic waste problem need to be efficiently managed. The purpose of this research is to study the manufacture of briquettes from PET and PP plastic waste with the help of starch adhesive. This research is expected to reduce the negative impact of plastic waste. In this study, the data to be obtained were the calorific value of the briquettes, ash content, moisture content, volatile content and bound carbon content. The results show that the best raw material combination in terms of the calorific value of the resulting charcoal briquettes is the raw material mixture with the addition of PET. The results of the PET type plastic briquettes were superior with the results of the calorific value test of 10.129 cal/gram, the proximate test results of 3.11% ash content, 4.98% moisture content, 65.31% volatile matter content, and 78% bound carbon content 79%. While the PP type plastic briquettes obtained a calorific value test result of 9,949 cal/gram, the calorific value was lower than the PET type plastic briquettes.

Abstract

The quality of corporate sustainability reports in Indonesia is unfortunately found to be lacking, with a rating of only 53.6%. This is significantly lower compared to the average of other Southeast Asian countries. However, stakeholders are becoming more aware of their role in encouraging public companies to disclose sustainability information. This study intends to look at the quality of sustainability reports released by Indonesian public firms, as well as the impact of stakeholder pressure on these reports' quality. Data from annual and sustainability reports of businesses listed on the Indonesia Stock Exchange between 2016 and 2020 are used in the research, which is based on GRI's G4 guidelines and the GRI Standards 2016. The study looks at numerous stakeholder pressures, including pressure from creditors, media exposure, the Big Four accounting firms, employees, consumers, environmentally sensitive industries, and shareholders. The results show that companies with significant media coverage typically produce sustainability reports of high quality. However, pressure from other stakeholders has not been found to have a significant impact on the quality of these reports. This study provides valuable insights into the state of sustainability reporting in Indonesia and aims to encourage stakeholders to actively participate in promoting a sustainable industry.

Abstract

Mount Semeru is an active volcano and the highest on the island of Java with an altitude of 3726 meters above sea level (masl). The last major activity of Mount Semeru which occurred on 04 December 2021, there was an eruption or Hot Cloud Fall (GAP). According to the Centre for Volcanology and Geological Hazard Mitigation (PVMBG, 2021), the GAP in this incident was directed towards the southeast of Mount Semeru, namely Curah Kobokan with a glide distance of up to 11 km. The area affected by GAP is a small part of Malang Regency and Lumajang Regency. The purpose of this study is to analyze the quality of groundwater resources in the Rejali watershed after the eruption of Mount Semeru in 2021. This type of research is quantitative research. All data obtained is processed using the Pollution Index (IP) method listed in the Decree of the Minister of Environment Number: 115 of 2003 concerning Guidelines for Determining Water Quality Status. The groundwater quality parameters used are pH, BOD, DO, TDS, Fe, Mn, TSS, and COD. The results of this study are, the pollution index value in segments 1-3 is moderately polluted, and in segments 4-5 is lightly polluted.

Abstract

Plastic waste is a global environmental problem that has existed for a long time and has not been resolved. On a worldwide scale, solid waste increased to 9.1 billion tons, of which 6.9 billion tons was plastic waste. Undip is one of the largest public universities.  As one of the universities that supports the achievement of SDGs Number 12 concerning waste management, Diponegoro University has a Waste Bank, namely the Dipo Waste Bank (DWB). The method used in this study is mass balance. Based on the projected waste generation from 2021-2030, the era of inorganic waste in the composition of plastic bottles at Undip is  42,577 kg/day. DWB is expected to realize independent and sustainable waste management within Diponegoro University (UNDIP). In its course, waste management efforts are felt to be lacking due to several obstacles and participation that are not optimal. There are three scenarios of reducing inorganic waste of  plastic bottles in  the study, namely the  baseline scenario,  the  Dipo Waste Bank (DWB) scenario can achieve the  target  of 20% of waste that can be recovered by DWB and Reverse Vending Machine (RVM).

Abstract

The Sekar Lepen Keprabon River is one of the tributaries polluted by domestic waste. This study aims to determine the water quality of the Sekar Lepen Keprabon River before and after filtering using SPZ (coconut fiber, banana fronds, zeolite stone) and SPA (coconut fiber, banana fronds, coconut shell charcoal) filter media. This experiment uses SPZ and SPA filter media to purify water that is applied directly to the river. The methods used were primary and secondary data collection. The data obtained were analyzed using a descriptive quantitative approach and the effectiveness of each parameter was calculated. The results of this study indicate that the water quality before and after filtering with SPZ filter media obtained a fixed temperature value, pH increased, COD and TSS increased, and TDS decreased. Water quality before and after going through the SPA filter media obtained a fixed value in temperature, pH increased, COD and TSS decreased, and TDS increased. SPZ filter media in the water filtration process is more effective in increasing pH parameters and reducing TDS parameters in river water. In contrast, SPA filter media in the water filtration process is more effective in reducing COD and TSS parameters in river water.
