Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh porositas kain tenun terhadap penyerapan zat warna menggunakan metode pengolahan citra digital. Porositas diukur melalui citra hasil pemindaian sampel kain dengan pendekatan thresholding menggunakan perangkat lunak berbasis Java. Metode statistik Kruskal-Wallis digunakan untuk menguji signifikansi perbedaan porositas dan nilai K/S antar jenis anyaman. Hasil menunjukkan korelasi negatif yang signifikan (r = - 0.858) antara porositas dan nilai K/S, dengan kontribusi porositas sebesar 73,65% terhadap variasi penyerapan warna. Jenis anyaman satin menunjukkan performa terbaik dalam penyerapan zat warna, sesuai dengan teori peningkatan kontak antar serat. Penelitian ini memberikan kontribusi pada pengembangan metode kuantitatif dalam evaluasi kualitas kain menggunakan teknologi pengolahan citra.

Abstract

Introduction : Microclimate is one of the environmental sciences related to plants in an area. This science describes the climatic conditions of the environment that have living organisms around it, either close to the surface of the earth or in confined environments such as a room, factory, and greenhouse. Measured the scale of studies of microclimate and environmental-climate vertically ranging from 1 meter to 2 meters. This research study used a field survey method by collecting environmental temperature data and observing tree architecture models growing in the campus area of Universitas Tadulako. The results of the study confirmed the most effective tree architecture models in minimizing the ambient temperature by investigating the aesthetic criteria of tree structures and characteristics in the campus environment of Universitas Tadulako.

Abstract

After the 7.4-magnitude earthquake, tsunami, and liquefaction disaster in September 2018, the Balaroa sub-district of Palu City was severely affected by liquefaction, which covered approximately 50 hectares with a perimeter of about 2.5 kilometres. This area was predominantly residential. Historically, residents of West Gunung Marawola avoided passing through this area when travelling to the Manonda Inpres Market, as the wheels of their carts would often become stuck. Consequently, the site was named Tagari Lonjo (a waterlogged and muddy area). This served as a form of natural mitigation, indicating that the site was unsuitable for habitation. This paper aims to establish a correlation between the initial conditions and the management of potential risks following the disaster. The research employs qualitative methods and utilises the Sendai Framework (as a conceptual foundation) and SWOT analysis (as a strategy formulation tool). The proposed design concept involves planning and utilisation of the former Balaroa liquefaction site, focusing not only on physical and ecological recovery but also on socio-economic revitalisation and strengthening resilience to future disasters. Based on the analysis, the geotechnical conditions of the former liquefaction site in Balaroa Village are recommended to be utilised as Ruang Natebuka Kodara (green open space) within land-use planning, with agrotourism potential that can foster economic self-reliance and help alleviate communal trauma. It is hoped that this paper will contribute particularly to education on mitigation and resilience, supporting regional sustainability through innovative post-disaster recovery strategies.

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.

Abstract

Penelitian ini bertujuan mengevaluasi efektivitas penerapan metode bantuan teman sebaya dalam meningkatkan hasil belajar gerakan sikap lilin pada pembelajaran senam lantai di SDN Sukamaju Kota Sumedang. Metode penelitian yang digunakan adalah observasi mengajar langsung dengan peserta didik dibagi dalam kelompok-kelompok kecil untuk saling membantu dan memberikan umpan balik. Hasil menunjukkan sekitar 70% peserta didik berhasil meningkatkan kemampuan mempraktikkan gerakan sikap lilin setelah menerapkan metode ini, dengan peningkatan signifikan dalam hasil belajar dan kepercayaan diri, sementara 30% lainnya masih mengalami kesulitan meskipun mendapat bantuan teman sebaya. Dapat disimpulkan bahwa metode bantuan teman sebaya efektif dalam meningkatkan hasil belajar sikap lilin, namun pendekatan tambahan atau modifikasi metode mungkin diperlukan untuk mengakomodasi kebutuhan peserta didik yang berbeda-beda, serta penelitian lebih lanjut untuk mengeksplorasi faktor-faktor lain yang mempengaruhi keefektifan metode ini dan mengembangkan strategi pembelajaran yang lebih komprehensif.
