Abstract

Aims: This paper investigates the ecological functional areas of Makassar City by utilizing land cover spatial data from 1997 and 2012 to evaluate ecological connectivity through Geographic Information Systems (GIS). Methodology and results: A spatial analysis of these ecological functional areas was conducted across different patch size categories to assess the percentage distribution of each land-use type. Additionally, the comparative distribution of the Ecological Connectivity Index (ECI) map for Makassar City was simulated. The findings indicate a decline in connectivity levels in previously natural areas surrounding Makassar, particularly in the western and eastern regions of the city. The ECIs have significantly decreased from 1997 to 2012, primarily due to the impacts of urban development in low-density, dispersed suburban areas. The results suggest that optimal quantitative criteria for ecological functional areas at the city scale of Makassar can be classified within patch size spectrum III. Implementing well-designed strategies could help mitigate the loss of ecological connectivity, thereby supporting the protection and restoration of Makassar’s environmental integrity. Conclusion, Significance, and Impact of Study: from a landscape ecological perspective, a significant trend observed in Makassar City over the past fifteen years has been the rapid fragmentation and transformation of its natural landscape. This has led to the emergence of numerous habitat patches that are progressively smaller and more disconnected. A thorough understanding of the interactions between spatial patterns and ecological processes across various scales is essential for effective landscape and environmental studies.
GEOGRAPHIC INFORMATION SYSTEM-BASED ASSESSMENT OF ENVIRONMENTAL CHALLENGES AND GREEN INFRASTRUCTURE PLANNING IN THE TALLO RIVER WATERSHED, MAKASSAR CITY Indrayani, Poppy; Djamaluddin, Ibrahim; Ritnawati, Ritnawati; Anugrah, Anugrah; Baso, Darwis; Hasnawi, Mursyid; Khaer, Miftahul; Asmeati, Asmeati; Honda, Hiroyuki; Kalla, Rastina; Meneisy, Ahmed M

Abstract

Aims: This study aims to explore the key issues and potential for implementing Green Infrastructure (GI) in the Tallo River area of Makassar, the largest city in Eastern Indonesia. Given its strategic location near the city center and its extensive undeveloped wetlands, the Tallo River region presents a valuable opportunity for sustainable urban development. The research emphasizes the need for integrated planning that addresses natural, economic, and social dimensions, positioning the Tallo River as a multifunctional resource capable of delivering diverse environmental benefits. Methodology and results: Using Geographic Information Systems (GIS) as a decision support and spatial analysis tool, this study evaluates environmental and socio-economic characteristics of the Tallo River area within the Green Infrastructure framework. Spatial data were analyzed to identify and map existing ecological functions, climate adaptation potential, and flood mitigation capacities. Through this process, various GI components and their functions were classified, and priority zones for Green Infrastructure implementation were delineated based on overlapping environmental and social values. Conclusion, significance and impact study: The findings highlight the critical role of GIS in supporting integrated urban planning and environmental management. Conceptualizing the Tallo River area as a multifunctional green space offers a pathway to enhance ecological resilience, address climate risks, and improve urban livability. This study provides actionable insights for policymakers and urban planners, reinforcing the significance of spatial analysis in guiding sustainable development strategies in rapidly urbanizing regions.

Abstract

Aims: This study aims to investigate the effect of binder variations on the compressive strength of eco paving blocks composed of four layered materials-rice husk, quartz sand, gravel, and activated carbon-each with a thickness of 6 cm. Methodology and results: The application is directed toward wastewater treatment using the rain garden method. Laboratory experiments were conducted to obtain reliable performance data. The results show that cement-bonded paving blocks demonstrate superior performance compared to those using fly ash binders. Cement adhesives ensured strong cohesion between layers, with blocks maintaining integrity during demolding without signs of damage or porosity. In contrast, paving blocks with fly ash binders required longer drying times due to the high moisture absorption of quartz sand, and they exhibited brittleness caused by weak adhesion. Extended curing was necessary before fly ash could adequately bond the base materials. Conclusion, significance and impact study: Quantitative findings revealed that paving blocks with cement adhesives achieved an average compressive strength of 836.25 MPa, higher than the 696.25 MPa of fly ash-bonded blocks. These results imply that cement remains the more effective binder for eco paving blocks in rainwater runoff and wastewater treatment, while fly ash requires optimization to improve its bonding performance. Eco-paving provides a nature-based, sustainable, and cost-effective solution for urban wastewater management, achieving both structural durability and effective pollutant removal.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efek penggunaan ultrafine Palm Oil Fuel Ash (UPOFA) dan ground Palm Oil Fuel Ash (GPOFA) sebagai bahan pengganti sebagian semen terhadap kekuatan dan laju penyerapan air (sorptivity) pada mortar ramah lingkungan. Total lima variasi campuran mortar disiapkan, yaitu mortar normal sebagai benda uji control, mortar dengan 10-30%UPOFA, dan mortar dengan 20%GPOFA. Semua variasi campiuran menggunakan faktor air semen (FAS) sebesar 40%. Pengujian kuat tekan dilakukan pada umur 7, 28 dan 56 hari dan pengujian laju penyerapan air dilakukan pada umur 28 hari sesuai standar ASTM C1585. Hasil menunjukkan bahwa penggunaan 10%UPFA menghasilkan perfoma terbaik dengan kuat tekan 32,93 MPA dan nilai laju penyerapan air terendah yang menandakan peningkatan densitas mikrosuktrur akibat reaksi pozzolan aktif. Sebalikanya penggunaan 20% GPOFA menunjukkan perfoma paling rendah dikarenakan ukuran partikel yang relatif kasar dan besar serta aktifitas pozzolan yang rendah. Sedangkan, penggunaan 20-30% UPOFA cenderung menurunkan efektifitas kuat tekan karena ketidakseimbangan antara material pengisi dan air hidrasi. Sehingga ditemukan bahwa penggunaan UPOFA dengan dosis optimum dapat meningkatkan kinerja mekanik dan ketahanan terhadap penetrasi air, sekaligus mendukung pengembangan material bangunan yang ramah lingkungan. Hasil ini membuka peluang lebih luas untuk pengaplikasian POFA dalam konstruksi beton yang berkelanjutan khususnya di wilayah tropis dengan potensi limbah biomassa sawit yang melimpah.
