Analysis of the Utilization of Putri Cempo Landfill Waste for Power Plants and Their Effects on the Surakarta Electric Power Distribution Network

Growth in electric energy demand, domination of use of fossil fuels, and waste problems are fundamental to this research. The purpose of this research is to find out the electrical energy potential of the Putri Cempo Landfill waste, Surakarta. The potential of electrical energy is designed for waste power plant (WPP). Penetration of WPP as a Distributed Generation (DG) to the 20 kV electrical distribution network is analyzed to determine its effect on the growth of demand for electricity, power flow, and the index of the (SAIFI and SAIDI). This research applies the technology Sanitary Landfill to produce landfill gas (LFG) as the primary energy of WPP. In calculating the growth predictions of electricity usage in the industrial, household, public, and commercial sectors from 2017 to 2025 in APJ Surakarta, the DKL Method 3.01 is applied. ETAP 12.6 was applied to analyze the power flow in the form of power losses and voltage losses and the Section method to calculate the reliability index (SAIFI, SAIDI) before and after penetration of WPP in PLR 01 and GDO 04 of Manahan Substation, Surakarta. The results showed that Trash from 5 Regencies and Cities, WPP was able to generate a maximum power of 10.1 MW. During peak load, WPP is able to reduce electricity demand of Substation for 0.920% in 2019, 0.879% in 2020, 0.838% in 2021, 0.799% in 2022, 0.760% in 2023, 0.723% in 2024, and 0.686% in 2025. The drop voltage at the tip of the feeder (No Substation Transformer BSP01005) has improved 29.4%, power losses have improved 25%, SAIFI has improved 61.36%, and SAIDI has improved 29%, after WPP penetration.

The potentials of and barriers to the utilization of advanced computer systems in remote construction projects: case of the Kingdom of Saudi Arabia

Abstract Background An extensive body of knowledge indicated the positive impact of the Advanced Computer based Management Systems (ACMS) on various aspects of project management, while highlighting barriers that hinder adoption, diffusion, and utilization of the ACMS by the construction industries around the world. Remote projects have their unique management problems and these are caused mainly by the remoteness of the project. Little research was undertaken concerning this issue, particularly in the Persian Gulf region, and it has highlighted few unique communications and management problems such as the loose control, lack of human resources, infrastructure and experience. Methods This research investigated the use of ACMS by large companies in the Eastern province, Kingdom of Saudi Arabia (KSA), and how it would help these companies sorting out a number of present projects’ management problems. Subsequently, a field study i.e. a questionnaire survey and interviews was carried out. Result The field study revealed significant association between frequent management problems with little use of ACMS and the domination of use of traditional communications and management systems. This paper argues that the use of traditional systems and the traditional way of sorting out construction problems limit the applicability of ACMS. Conclusion The present researchers recommend the use of customized ACMS associated with the application of lean and sustainable management principals as these would help overcoming barriers and providing intelligent solution for the strategic, technical, and social issues of the remote construction sites.

Swarm planning for climate change: an alternative pathway for resilience

Swarm planning is a theory and practical approach to deal with uncertain futures. By anticipating scenarios such as a ‘post-carbon’ world and a ‘pre-adaptive’ landscape, it offers an alternative pathway to prepare for medium-term incremental and step changes. The focus is on the regional scale with a planning process to move from an unstable state (i.e. due to external impacts of climate change) towards a state of higher adaptive capacity. It increases the flexibility of spatial systems in two ways: assisting change in spatial land use over time; and catalysing the emergence of autonomous and more resilient developments. Swarm planning theory is used in two pilot designs and compared with regular planning processes. The results are presented in the form of new landscapes: the ‘Zero-Fossil Region’, where the design provides a spatial framework for a complete renewable energy supply, and the ‘Net Carbon Capture Landscape’, in which adaptation and mitigation strategies are designed to become carbon positive. The comparison illuminates the potential advantage of swarm planning to tackle climate change threats. La planification en essaims est une théorie et une approche pratique visant à traiter des avenirs incertains. Au moyen de scénarios prospectifs tels que celui d'un monde « post-carbone » et d'un paysage « préadaptatif », elle offre une voie alternative pour se préparer à des changements progressifs ou radicaux à moyen terme. L'accent est mis sur l’échelle régionale, avec un processus de planification permettant de passer d'un état instable (c'est-à-dire dû aux incidences extérieures du changement climatique) à un état présentant une plus grande capacité adaptative. Cela accroît de deux manières la flexibilité des systèmes spatiaux : en favorisant le changement dans l'utilisation spatiale des terrains au fil du temps; et en catalysant l’émergence de développements autonomes et plus résilients. La théorie de la planification en essaims est utilisée dans deux conceptions pilotes et comparée aux processus de planification habituels. Les résultats sont présentés sous la forme de nouveaux paysages : la « Région Zéro Energie Fossile », dans laquelle la conception fournit un cadre spatial permettant un approvisionnement énergétique entièrement renouvelable, et le « Paysage à Séquestration Nette de Carbone », dans lequel des stratégies d'adaptation et d'atténuation sont conçues pour assurer un bilan carbone positif. Cette comparaison se révèle éclairante quant à l'avantage potentiel de la planification en essaims pour s'attaquer aux menaces posées par le changement climatique.
