Abstract

The management of urban plastic waste poses a significant challenge for the global environment and economy. An innovative horizontal tube pyrolysis reactor with a tiered condensation system, designed for a capacity of 50 kg, has been developed to convert mixed plastic waste into liquid fuels such as diesel, kerosene, and gasoline through an efficient and environmentally friendly pyrolysis process. The reactor, with a diameter of 760 mm and a length of 1200 mm, maximizes heat distribution to ensure uniform heating without requiring mechanical rotation or stirring. External heating is maintained at a temperature range of 300°C to 350°C under anaerobic conditions to prevent direct combustion. System trials demonstrated that the conversion of plastic waste to liquid fuel products can achieve an efficiency of up to 70% of the total input mass, yielding an average of 50% liquid fuel fractions, 15% solid residue, and 35% pyrolysis gas. Analysis of the liquid fuel quality indicates hydrocarbon content comparable to conventional fuels, with potential applications in internal combustion engines. The system is designed to be self-sufficient, utilizing pyrolysis gas to sustain the process and thereby reducing external energy requirements by up to 30%. These findings highlight the significant potential of horizontal tube-based pyrolysis systems in efficiently reducing urban plastic waste while providing alternative fuel sources. This technology can thus support sustainable waste management efforts and contribute to the transition toward renewable energy.

Abstract

Mangrove degradation and socio-economic vulnerability in the Kendal coast require an integrated approach. The study used ecological surveys (mangrove vegetation analysis, avifauna) and socio-economic (n=186 households). Integrated Coastal Management (ICM) analysis and model were developed using a dynamic approach, encompassing problem identification, conceptual model formulation, and validation preparation. 14 mangrove species (H' index = 1.58–1.80) and 61 bird species (H' = 3.50) were found. Community participation reached 97%, but women's participation was only 3%, with 58% of households being landless and 61% unproductive land. Infrastructure was severely damaged (36% of roads) and 97% of the area was flooded. The dynamic model of ICM in Kendal Regency highlighted coastal biodiversity conservation, enhanced community capacity and participation, and secure land ownership as the primary drivers of sustainable coastal governance. Despite ongoing pressures from coastal hazards and urban expansion, biodiversity conservation remained the pivotal intervention, sustaining ecosystem integrity, improving household incomes, and reinforcing socio-economic resilience through positive feedback loops within the coastal social–ecological system.

Abstract

While the experience of working abroad can provide new skills and knowledge, former migrant workers often face challenges in reintegrating into the local labor market upon returning to Indonesia. Malaysian migrant workers have a tendency to work for less than the minimum wage after returning to Indonesia. Using the August 2021 sakernas data and logit analysis, this study will discuss the probability of former Indonesian migrant workers with a destination country of Malaysia, to earn wages above or equal to the minimum wage in the place where they work. The results of the logit analysis show that former Indonesian migrant workers have a probability of earning a living wage upon returning to Indonesia. Those who have a greater probability are former migrant workers with male gender, have higher education and have a formal job after returning to Indonesia.

Abstract

Tambakrejo Village is one of the areas in Semarang City that is often affected by flooding, administratively it is included in Gayamsari District. Being in a coastal area with an elevation close to sea level means that the Tambakrejo District area has the risk of flooding and tidal problems, where tidal disasters have so far submerged more than 2.5 hectares of land with 25 residents' houses lost. Flood and tidal conditions directly or indirectly affect all aspects of people's lives. The impact of disasters results in damage to facilities and infrastructure, disruption of social activities, education and public health. If this continues, it is feared that it will increase community vulnerability and decline. The aim of the DPIK program is to increase community capacity to have the independent ability to adapt in facing potential disasters and other impacts of climate change, through the Smart and Disaster Resilient Village movement.
