Abstract

Changes in the river morphology require knowledge of the suite of drivers that control it, whether natural or human. The study aims to analyze the anthropogenic influences on morphological changes in the Progo River using Google Earth Images. It is essential to know the recent changes in the morphology of the Progo River so that stakeholders can make policies to control human activities that influence the morphology changes of the Progo River. The study area is located in Bantul Regency, Daerah Istimewa Yogyakarta Province, Java Island, Indonesia. The size of ​​the Progo River watershed is around 17,432 square kilometers. Google Earth Images analysis is carried out to analyze the morphological changes of the Progo River from 2012 to 2019. The result shows that land-use changes due to dam construction affected the sediment supply downstream of the dam. In addition, land-use changes around the Progo River due to the opening of agricultural land and settlement areas had an effect on decreasing the infiltration area, so that the number of trees holding the soil from erosion was reduced, producing more eroded sediment that flowed to the river. Sand mining in the river could cause the deepening of water depths and a decrease in the average height of the riverbed.

Abstract

The purpose of this study is to evaluate Corporate Social Responsibility (CSR) programs for local communities around mining companies in Kalimantan, Indonesia, based on environmental, economic, and social perspectives. We create evaluation criteria consisting of; six on the environmental perspective, three on the economic perspective, and two on the social perspective. CSR reports are collected from the company website. Each company was given a score based on whether these evaluation criteria were present (1) or absent (0). The evaluation scores of the CSR mining companies programs’ in Kalimantan, Indonesia are high in considering cleaner production, waste reduction, material flow management, and recycling, committed to managing energy and water, developing infrastructures surrounding mining companies, has good corporate ethics, and encourages employees to volunteer for social causes and provides incentives for these activities; medium in committed to following all applicable laws and policies concerning environmental standards and policies, committed to conserving biodiversity, committed to managing sound and vibration from mining activities as well as protecting the air quality around the mining area, and enhancing self-employment options for local communities; low in taking long-term factors into accounts, such as global climate change and other environmental threats, and providing jobs opportunities for local communities. From the evaluations above, access to information, public participation, and transparency in discussing areas of corporate-community issues are all things that mining companies must improve. If there is a lack of congruence between aim, activity, and effect, civil society organizations should frequently criticize mining companies' CSR operations.
