A Socio-Ecological Approach to GIS Least-Cost Modelling for Regional Mining Infrastructure Planning: A Case Study from South-East Sulawesi, Indonesia

Regional planning approaches to mining infrastructure aim to reduce the conflict associated with mining operations and existing land uses, such as urban areas and biodiversity conservation, as well as the cumulative impacts that occur offsite. In this paper, we describe a method for conducting Geographical Information System (GIS) least-cost path and least-cost corridor analysis for linear mining infrastructure, such as roads. Least-cost path analysis identifies the optimal pathways between two locations as a function of the cost of traveling through different land use/cover types. In a case study from South-East Sulawesi, Indonesia, we identify potential linear networks for road infrastructure connecting mines, smelters, and ports. The method used interview data from government officials to characterise their orientation (perceived importance and positive/negative attitude) toward the social and environmental factors associated with mining infrastructure. A cost-surface was constructed by integrating spatial layers representing the social and environmental factors to identify areas that should be avoided and areas that were compatible with linear infrastructure using the least-cost path analysis. We compared infrastructure scenario outputs from local and national government officials by the degree of spatial overlap and found broad spatial agreement for infrastructure corridors. We conclude by discussing this approach in relation to the wider social-ecological and mine planning literature and how quantitative approaches can reduce the conflict associated with infrastructure planning

Improving Students Learning Activeness in Social Studies Subjects through Student Teams Achievement Division (STAD) Cooperative Learning Model

This research is motivated by the problems found in class VII E at SMPN 2 Pamekasan, namely the low level of student learning activeness in social studies lessons, in the classroom the teacher still uses the lecture method in explaining the learning material and continued with practice questions, as a result learning activities become unvaried and limited. cooperative learning model type Student Teams Achivement Division (STAD) is used to increase student activeness. This research used classroom action research (PTK) which was carried out in two cycles, each cycle consisting of four stages, namely the planning, implementation, observation, and reflection stages. The subjects of this study were students of class VII E consisting of 32 students. The research instruments used in this study were observation guidelines for student learning activeness, and field notes. While the data collection techniques used in this research are participatory observation, interviews, and documentation. The data analysis used is qualitative data analysis, which consists of data reduction, data presentation, and conclusion drawing, and quantitative data analysis with a percentage of the assessment of student learning activeness in the application of the Student Teams Achivement Division (STAD) type cooperative learning model. Based on the results of the study it can be concluded that there is an increase in student learning activeness in social studies learning from cycle I to cycle II. Indicators pay attention to the teacher's explanation increased 12.51% from cycle I to cycle II. Indicators record or summarize the subject matter increased 28.13% from cycle I to cycle II. Indicators asking questions to teachers or friends experienced an increase of 26.57% from cycle I to cycle II. Indicators answering questions from teachers or friends increased 39.06% from cycle I to cycle II. Indicators discussing with group members in solving problems increased 21.88% from cycle I to cycle II. Indicators helping fellow group members in understanding the subject matter increased 14.07% from cycle I to cycle II. The indicator of doing tasks given by the teacher increased 28.12% from cycle I to cycle II. The indicator of doing quizzes individually increased 39.06% from cycle I to cycle II. And student learning activeness showed a score of 93.75% at the end of the cycle

Gendered informal gold trading in Indonesia: Case studies from Central Kalimantan

This paper examines the gendered aspects of informal gold trading along the artisanal and small-scale gold mining (ASGM) value chain in Indonesia. Indonesian law allows ASGM to be carried out by individuals, groups, families or cooperatives with limited investment and capital. However, only a very small percentage of ASGM activities are licensed, resulting in gold being traded predominantly within informal networks. The authors carried out a study of artisanal gold mining in two mining sites in Central Kalimantan, Indonesia. Primary data from the field were collected during COVID-19 in the form of semi-structured interviews and participatory data collection methods such as gender mapping and business analysis. This paper argues that gold trading in informal, artisanal, and small-scale gold mining is gendered as a function of unequal power relations between women and men who operate in different parts of the ASGM value chain network

Optimising government assets in Jakarta, Indonesia, post relocation of the capital city

The Indonesian government has proposed that the capital city be relocated from Jakarta, the existing capital city, to Nusantara, the new capital on Kalimantan Island. Talk of relocation has been mainly triggered by the issues of overcrowding, sinking, and high frequency floods due to climate change in Jakarta. It is anticipated that the capital city relocation will have significant impacts on central government office buildings in Jakarta, including many government officials and their associated public services being transferred to Nusantara. As a result, there will be an oversupply and underutilisation of government buildings in Jakarta.To date, there has been limited research to evaluate the consequences of the capital city relocation on the central government office buildings, especially when climate change risk is considered. Thus, this research was conducted with two key objectives:1. To investigate and to develop a deeper understanding of the social, economic, and environmental factors involved in the relocation of government building users in Jakarta, and the impacts on remaining stakeholders and built assets.2. To develop an asset lifecycle management framework that considers the concepts of sustainable building and climate change adaptation, to optimise the utilisation of the vacant and underused buildings due to the relocation of Jakarta.The main output of this research project is the development of an asset lifecycle management framework that integrates sustainable building and climate change building impacts. The framework aims to contribute to the policy development for the repurposing agenda of underutilised central government assets including office buildings, post-relocation of the capital city. The framework was also informed by the research findings, especially the views of key stakeholders on the concept of sustainable building, climate change building adaptation and building optimisation, such as the decision to repurpose vacant or underutilised buildings

Challenges and Opportunities for Promoting Sustainability in Public Buildings

The building and construction sector remains largely climate-unfriendly as a significant global greenhouse gas emitter. Public buildings can play a significant role in promoting sustainability practices. Unlike developed countries that have successfully promoted sustainable building practices, developing countries have experienced slow progress in implementing sustainable practices in public buildings. This research study investigated the challenges and opportunities for improving sustainability practices in public buildings from a multi-stakeholder perspective within the context of developing countries. Using Indonesian public buildings as a case study, a wide range of stakeholders directly involved in the public building sector such as policy-makers, building owners, building professionals, and building users were interviewed over two time periods of 2019 and 2023. The interview results show consistent findings on challenges and possible opportunities with respect to regulation, occupant behavior, and the primacy of technical intervention in the practice of sustainable buildings. Despite the importance of strong policy and the role of technology in sustainability practices in public buildings, this study advocates the need for greater intervention in occupant behavior so that sustainable practices in public buildings can be continuously promoted
