Abstract

Serpentinite rock is one of the mineral sources of magnesite this is known by the considerable content of the element magnesium (Mg). Testing the physical and chemical properties of serpentinite rocks found in certain locations is considered to have considerable prospects to be utilized and developed. The research was conducted in Uekuli Village Tojo Una-Una Regency Central Sulawesi Province using X-Ray Diffraction (XRD) and X-Ray Flourescence (XRF) methods. The results of XRD analysis obtained 4 types of minerals in the ST 02 test sample namely olivine as much as 3.4% lizardite 72.4% forsterite 18.6% and orthopyroxine as much as 5.6%. While at station 09 2 minerals were obtained namely lizardite 97.5% while hematite was 2.5%. Meanwhile based on the results of XRF testing the ST 02 sample has a dominant compound of MgO as much as 42.754% and SiO2 as much as 43.185%. Similarly the ST 09 sample has a dominant compound of MgO as much as 39.314% and SiO2 as much as 40.866%. In the analysis results it can be seen that the content of Al2O3 and K2O is quite low while the content of MgO and Fe2O3 is quite high. The high content of MgO and SiO2 is a characteristic of serpentinite rocks where serpentinite rocks are rich in magnesium and silica.

Abstract

Soil erosion is a critical environmental issue that directly contributes to land degradation and reduced productivity in watershed areas. This study aims to analyze the dynamics of soil erosion hazard in the Olaya Watershed, Central Sulawesi, using the Universal Soil Loss Equation (USLE) model integrated with Geographic Information Systems (GIS). The analysis was conducted for two temporal periods, 2020 and 2023, to assess changes in erosion rates and the spatial distribution of erosion hazard. The model incorporates key parameters including rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), and land cover-management factor (CP). All spatial data were processed in raster format and analyzed using ArcGIS 10.7 software. The results indicate that the average annual soil erosion rate decreased from 333.70 tons/ha/year in 2020 to 173.57 tons/ha/year in 2023. This decline was influenced by changes in rainfall erosivity. Based on the Erosion Hazard Index (EHI) classification, most of the watershed area was categorized as having severe erosion hazard in 2020, which shifted to moderate in 2023. These findings highlight the importance of spatio temporal monitoring in watershed management and the urgent need for land conservation efforts based on prioritized zonation to mitigate erosion risks in tropical regions. Keywords: soil erosion, land conservation, USLE model, geographic information system, erosion dynamics, Olaya Watershed

Abstract

Abstract The use of plastic additives in various items such as household appliances and electronics is common in society. One type of plastic, Polyethylene, is produced through the polymerization process of ethylene gas. However, plastic is difficult to decompose naturally, requiring hundreds of years to decompose completely. Therefore, the utilization of plastic waste into building materials such as concrete is an innovative alternative, especially PET (Polyethylene Terephthalate) plastic from recycled beverage bottles. This study aims to determine the compressive strength of concrete with coarse aggregate added from PET plastic waste. In Banggai Regency, the use of plastic waste in concrete has not been carried out or tested with local materials. This study was conducted experimentally in the Banggai Regency laboratory with PET variations of 0%, 3%, 6%, and 9%. The highest results were obtained in a mixture of 3% PET with a water cement ratio (FAS) of 0.5, namely 25 MPa. Meanwhile, FAS 0.6 produced the highest compressive strength in the 0% PET variation, namely 19.9 MPa. The difference in results in the 3% PET variation between FAS 0.5 and 0.6 reached 26%. This shows that the FAS composition and PET content have a significant effect on the compressive strength of concrete.. Keywords: concrete, concrete compressive strength, PET plastic, additional materials

Abstract

Microbial self-healing concrete offers an innovative solution to address the problem of cracks in modern infrastructure, but its field application is hindered by the viability of bacteria within the harsh concrete matrix. This systematic literature review aims to explore the development of encapsulation technology as a strategy to enhance the performance of microbial self-healing concrete. The methodology includes a comprehensive search of major academic databases using a combination of specific keywords, and article selection based on strict inclusion and exclusion criteria. Analysis found that a diverse range of encapsulation technologies have been adopted, including the use of sodium silicate-coated Recycled Coarse Aggregate (RCA), fly ash, cement shell microencapsulation, biopolymer encapsulation, pH-sensitive hydrogels, and modified manufactured aggregates. These technologies significantly enhance bacterial viability and the effectiveness of the self-healing process, resulting in more efficient crack closure and improved mechanical properties and durability of the concrete. Nevertheless, significant challenges still include the long-term viability of bacteria, limitations in the scale of field application, and the high cost of encapsulation production. Future research prospects focus on developing more robust bacterial strains, more economical encapsulation strategies, comprehensive field-scale validation, and integration with sustainable materials and machine learning for design optimization. This research concludes that the development of essential encapsulation technology is crucial in advancing microbial self-healing concrete applications toward more durable and environmentally friendly construction solutions.

Abstract

The increasing risk of disasters in urban areas demands a new spatial planning paradigm that prioritizes disaster risk reduction (DRR). Public Open Spaces (POPs) not only serve as aesthetic and recreational elements but also have the potential to serve as strategic soft infrastructure in integral disaster management, as demonstrated by current literature and regulations. This study aims to analyze the role of POPs in supporting urban resilience by integrating disaster mitigation concepts into urban spatial planning in Indonesia. The study uses descriptive qualitative literature review with analysis of national regulations (Law No. 24 of 2007, Regulation of the Minister of Agrarian Affairs and Spatial Planning/National Land Agency No. 14 of 2022), international frameworks (Sendai Framework, UNDRR), and academic literature related to the disaster management cycle and risk-based urban planning. The results show that POPs have a significant role in four phases of disaster management: (1) mitigation as an ecological buffer zone; (2) preparedness as a training location and assembly point; (3) emergency response as an evacuation space and logistics center; and (4) recovery as a place for socio-psychological rehabilitation. The application of the dual-use planning concept optimizes the RTP function under both normal conditions and in crises. This research contribution strengthens academic understanding of the integral relationship between green infrastructure,spatial planning, and risk reduction and offers policy recommendations for more effective implementation at the local level. The conclusion is that integrating RTP into risk-based spatial planning is a crucial investment for building resilient, sustainable, and disaster-resilient cities in the future.
