Abstract

Dukuh Papringan, Sleman, Yogyakarta, is an urban area predominantly inhabited by university students from various institutions. These students hold a strategic role in promoting the adoption of renewable energy to reduce dependence on fossil fuels, which leads to high energy costs and significant carbon emissions. This study aims to analyze the potential of renewable energy in Dukuh Papringan, its economic, social, and environmental benefits, and the role of students in supporting the implementation of clean energy technologies. The research employs a qualitative approach through interviews, field observations, and secondary document analysis. The findings indicate that Dukuh Papringan has significant solar energy potential, with an average radiation of 4.8–5.5 kWh/m²/day, along with opportunities for organic waste processing into biogas. The implementation of renewable energy technologies can reduce energy costs by up to 30% and carbon emissions by 40%. Students act as educational agents, initiators of community projects, and researchers in clean energy technology innovation. The success of renewable energy adoption requires synergistic support from the government, universities, and the private sector. Dukuh Papringan has the potential to serve as a model for sustainable energy management in urban areas, contributing to national targets for carbon emission reduction and accelerating the transition to clean energy.

Abstract

Waste-to-Energy (WtE) technology offers an innovative solution to improve sustainable waste management, especially in areas with significant waste management challenges such as Nganjuk Regency. This study explores the opportunities for implementing WtE in Nganjuk to reduce waste volume, reduce greenhouse gas (GHG) emissions, and provide alternative energy sources. By utilizing technologies such as incineration, pyrolysis, and gasification, WtE facilities can convert waste into renewable energy, reduce dependence on landfills, and reduce methane emissions that contribute to global warming. The results show that WtE implementation can generate environmental and economic benefits, including providing energy for local communities and reducing waste management costs. Community education and active participation in recycling and waste sorting programs are also key to the success of WtE implementation. Government policy support and incentives are identified as important factors in facilitating the adoption of this technology. This study provides important insights for the development of sustainable waste management strategies in Nganjuk and can serve as a model for other areas facing similar challenges. The recommendations provided include increasing cooperation between the government, private sector, and communities to maximize the potential of WtE technology in supporting sustainable development and climate change mitigation. Considering the composition of waste which mostly comes from household waste, where 61.5% is organic waste, the right WtE technology is a biodigester

Abstract

Wood preservation aims to enhance durability against environmental degradation and extend its service life. Conventional methods often use synthetic chemicals that negatively impact the environment. This research develops a wood coating and impregnation technique using waste plastic melted in used cooking oil as a penetration medium, offering an eco-friendly and economical solution. The five types of wood tested are bengkirai, glugu, teak, sengon, and melinjo, each with different physical characteristics and porosity. Evaluation was conducted on specific gravity (SG), porosity, expansion, and shrinkage of the wood. The results showed that soaking in the plastic-oil solution increased SG and reduced porosity, particularly in highly porous woods such as sengon and glugu. The rate of plastic impregnation into the wood followed an exponential model with significant variation between wood types. ANOVA analysis confirmed that wood type and soaking duration significantly influenced changes in the physical properties of the wood. The low-carbon development concept is applied by utilizing waste plastic and used cooking oil, reducing carbon emissions from waste incineration, and supporting the circular economy. This method can become a more sustainable, recycled-based wood preservation alternative that supports environmental sustainability

Abstract

Oil palm plantation management in Indonesia faces significant challenges in terms of operational efficiency, land monitoring accuracy, and compliance with sustainability standards. With the advancement of digital technology, the use of drones or Unmanned Aerial Vehicles (UAVs) has emerged as a potential solution to enhance plantation management effectiveness. This study aims to examine the effectiveness of drones in supporting oil palm plantation management in Indonesia through a review of both national and international literature. The findings indicate that drones can provide high-resolution spatial data quickly and accurately, which can be integrated with Geographic Information Systems (GIS) for planting block mapping, crop growth monitoring, pest infestation detection, and land fertility evaluation. Several studies have reported mapping efficiency improvements of up to 60%, along with support for sustainability reporting such as ISPO and RSPO. The use of drones also supports precision agriculture approaches, particularly in variable-rate fertilization and zonal land management. Despite implementation challenges such as investment costs and a shortage of trained operators, drone technology holds significant potential for the digitalization of plantations. This review recommends enhancing UAV adoption through technical training, strengthening digital infrastructure, and formulating supportive operational regulations. The integration of drones into oil palm plantation management is believed to accelerate the transformation toward a more efficient, accurate, and sustainable precision agriculture system.

Abstract

This study aims to evaluate the efficiency of transporting Fresh Fruit Bunches (FFB) from the Harvesting Point (TPH) to the Palm Oil Mill (PKS) using a fleet of company-owned and contractor-owned dump trucks at PT Persada Sejahtera Agro Makmur. Parameters analyzed included travel time, load capacity, fuel consumption, operational costs, and estimated carbon emissions using the IPCC 2019 approach. The results show that the company's dump trucks have shorter travel times, larger load capacities, lower fuel consumption, and lower hourly operating costs than the contractor's dump trucks. Annual carbon emissions from the company's dump trucks are 27,389 kg CO₂, while the contractor's dump trucks produce 29,346 kg CO₂. Simulations of converting to B50 biodiesel and electric vehicles indicate potential energy cost savings of up to IDR 1.47 billion and emission reductions of up to 1,013 tons of CO₂ over five years. This research supports the development of a low-carbon logistics system in the palm oil plantation sector
