Abstract

Fenomena pemanasan global yang disebabkan oleh efek gas rumah kaca erat kaitannya dengan aktivitas pembangunan. Oleh sebab itu diperlukan pola pembangunan yang sekecil mungkin pengaruhnya terhadap lingkungan yang kemudian disebut dengan Pembangunan Berkelanjutan yang Berwawasan Lingkungan. Salah satu bagian dari pembangunan berkelanjutan adalah konstruksi berkelanjutan, salah satu aspeknya adalah melakukan konservasi terhadap penggunaan sumberdaya alam. Disisi lain, volume limbah yang dihasilkan mencapai 19,5 kg/m2 akibat aktivitas pembangunan proyek baru sedangkan akibat pembongkaran bangunan adalah 757 kg/m2. Oleh karenanya diperlukan tindakan nyata untuk memanfaatkan limbah tersebut dengan cara reuse dan recycle. Data dan informasi diperoleh melalui wawancara langsung terhadap pelaku usaha material bekas bangunan yang berada di beberapa kota besar di pulau Jawa. Hasil yang diperoleh adalah jenis material bekas yang banyak digunakan kembali adalah bahan yang terbuat dari kayu dan besi dengan alasan hasil bongkaran bangunan mengalami kerusakan relatif kecil pada saat pembongkaran dan dapat digunakan kembali melalui proses perbaikan dan atau reproduksi. Aspek positif membeli bahan bangunan di pasar loak adalah dapat membeli material sesuai dengan kebutuhan serta mendukung konservasi sumberdaya alam sedangkan aspek negatifnya adalah kontinuitas ketersediaan jenis material kurang terjamin.

Abstract

Abstract: Surface morphology, surface material, greenery, anthropogenic heat and air pollutants are known as the elements that determine the thermal environment performance. These elements, hence, should determine the outdoor thermal comfort level. However, previous studies mentioned that the role of psychological adaptation in outdoor thermal comfort is greater than in the indoor. Therefore, exploring perceived elements, which determine the thermal environment, could enrich the perspective of a design approach of thermally comfortable open spaces. This study aims to explore the perceived elements of thermal environment, which contribute to the outdoor thermal comfort using open-ended questions of an online questionnaire. Several keywords obtained by the content analysis of 101 respondents’ answers affirm the role of the thermal environment elements in modifying the thermal environment. Tree or greenery, the most frequently appeared keyword, showed as the strongest perceived element. New keywords that significantly appeared; i.e. visual aspects, supporting facilities, and tranquility; indicate the importance of thermo-spatial perception approach in designing livable and thermally comfortable outdoor environment.Keywords: elements of thermal environment, outdoor thermal comfort, perception, psychological adaptation,Abstraksi: Morfologi permukaan, permukaan material, area hijau, panas antropogenik dan polutan udara diketahui sebagai elemen-elemen yang menentukan performansi lingkungan termal. Dengan demikian, elemen-elemen tersebut seharusnya menentukan tingkat kenyamanan termal outdoor. Namun, beberapa studi menyebutkan peranan adaptasi psikis pada kenyamanan termal outdoor yang lebih besar dibandingkan pada kenyamanan termal indoor. Oleh karenanya, eksplorasi elemen-elemen yang dipersepsikan menentukan lingkungan termal dapat memperkaya perspektif pendekatan studi ruang terbuka yang nyaman secara termal. Studi ini bertujuan untuk menggali elemen-elemen lingkungan termal yang dipersepsikan berperan pada kenyamanan termal outdoor dengan menggunakan pertanyaan-pertanyaan yang bersifat open-ended di dalam kuesioner online. Beberapa kata kunci yang dihasilkan oleh analisis konten dari 101 responden mengkonfirmasi peranan elemen-elemen lingkungan termal di dalam memodifikasi lingkungan termal. Pohon atau greenery, kata kunci yang paling sering muncul, menunjukkan sebagai elemen yang dipersepsikan paling kuat. Kata kunci baru yang muncul secara signifikan, yaitu: aspek visual, fasilitas penunjang, dan ketenangan; mengindikasikan pentingnya pendekatan persepsi termo-spasial di dalam merancang lingkungan outdoor yang hidup dan nyaman secara termal.Kata kunci: adaptasi psikis, kenyamanan termal outdoor, persepsi, unsur-unsur lingkungan termal

Abstract

Understanding the physical phenomena is extremely aided by digital simulations for understanding physical phenomena that occur, especially for students in the digital era and in this new-normal period. This paper describes heat conduction in solids using the Energy2D program, starting from general formulations for heat conduction from conductors to general solids that show the mechanism of heat conduction as a diffusion process. The thermal diffusivity parameter determines heat diffusion as the ratio between thermal conductivity and multiplication between density and thermal capacity. From the practical side, heat conduction is ordinary using thermal resistance (R-value) that combines the dimensions of the material in the direction of heat flow and thermal conductivity. By taking an analogy with Ohm's law for electrical circuits, it can be determined the equivalent resistance of several thermal resistance of the material that is composed in series or parallel. A good understanding of the heat transport process in buildings is needed for the development of technologies required for the comfort of human life and energy conservation. DOI: http://dx.doi.org/10.17977/um024v5i12020p011

Abstract

Grounded theory pada prinsipnya merupakan salah satu pendekatan penelitian kualitatif yang sangat dinamis, di mana proses yang cair dan kompleks akan memberikan hasil temuan berdasarkan inovasi dan kekokohan sudut pandang teori yang dibangun. Penerapan grounded theory dalam bidang arsitektur dan lingkungan binaan masih terbatas sehingga penelitian ini membahas tentang upaya penerapan grounded theory dalam penelitian arsitektur dan lingkungan binaan. Metode penelitian yang digunakan melalui kajian literatur dari berbagai sumber pustaka berdasarkan teori, data dan hasil penelitian di bidang arsitektur dan lingkungan binaan kemudian dikaji dengan pendekatan penelitian kualitatif grounded theory. Hasil penelitian menunjukkan bahwa dalam menghasilkan dan mengaktualisasikan konsep teori baru dalam bidang arsitektur dan lingkungan binaan, pendekatan grounded theory menjadi sangat relevan untuk dikembangkan karena sejalan dengan paradigma desain arsitektur saat ini yang berorientasi pada faktor kenyamanan psikologis, ekonomi, energi, keberlanjutan, mitigasi bencana, lingkungan hidup, dan teknologi yang terus berkembang. Sedangkan tantangan penerapan grounded theory dalam penelitian arsitektur dan lingkungan binaan adalah kesulitan penentuan level jenuh dan perbedaan latar belakang responden/informan yang memberikan hasil sebaran yang beragam sehingga perlu dianalisis dan dipahami secara rinci lebih mendalam sebagai suatu kesatuan dalam desain penelitian

Abstract

In recent decades places that use attractive urban lighting to attract visitors have emerged. This shows a shift in lighting, giving the impression of a place, nocturnal image, and attracting attention. The purpose of this paper is to explore places, activities, and impressions of attractive urban lighting to see its potential in improving city visuals at night. The data was collected through an online questionnaire distributed by a non-random snowball sampling method from 126 respondents. The analysis was carried out in stages, starting with content analysis and continued with correspondence analysis and hierarchical clustering. The results showed that places with attractive urban lighting could be grouped into seven categories of place, ten categories of activity, six categories of impression. Three models are formed from these themes, namely cognitive image, unique images, and affective image, which will form an overall image of attractive urban lighting as the new destination branding.

Abstract

This research will describe experimental research methodology using computer simulation with the case study of urban cool island research. The urban cool island is one of the urban heat island mitigation technology strategies. This technology uses a geometric and material intervention process that forms an urban cool island in an area with high urban heat island intensity. The urban cool island will expand and reduce the temperature of the hot islands so that the urban heat island gets smaller. In the research process, a series of experimental methodologies were carried out. Experimental methodology is carried out on a regional scale will be difficult and expensive. So a computer simulation is needed to facilitate urban cool island experiments in the area. The stages of experimental research with computer simulations use two process stages (1) Quasi-measurement experiments and field observations in the UCI area, (2) Validation of field measurements versus simulation models, (3) Experiments with computer simulations by creating test models and comparison models. The scope of research on the scale of urban areas with experimental methodology becomes efficient with the help of computer simulations. In Urban Cool Island, several countries have also used this methodology. Computer simulation used: ENVI-MET, CFD-Ansys, and others. Before starting the research, a clear frame or research design is needed, determining variables, replicating the real conditions, mastering the use of simulations, and always paying attention to the results, which are continuously controlled and validated to produce simulations that are close to the real conditions.

Abstract

The implementation of thermal insulation within the walls of building constitutes a pivotal strategy aimed at mitigating cooling loads and augmenting energy efficiency, particularly in tropical climate conditions. In the preceding decade, scholars have progressively utilized both empirical and computational methodologies to evaluate the efficacy of insulation under diverse environmental and material parameters. Aims:  This study undertakes a comprehensive review of methodological frameworks in the domain of thermal insulation research for building walls conducted between 2020 and 2024, with an emphasis on hybrid experimental design that integrate physical measurements with digital simulations to yield more accurate, dependable, and contextually pertinent data. Methodology and results: A systematic literature review (SLR) encompassing 52 scholarly articles was performed, categorizing the studies into four distinct classifications: field studies, laboratory-based investigations, digital methodologies (e.g., EnergyPlus, TRISCO, ABAQUS), and hybrid methodologies. Among these, digital experimentation emerged as the most predominant methodology, with EnergyPlus identified as the most frequently utilized instrument. Research employing hybrid methodologies demonstrated enhanced analytical rigor through cross-validation, versatile scenario exploration, and comprehensive thermal performance assessment. Conclusion, significance, and impact study: Combining empirical data with digital experimentation significantly improves the precision and contextual relevance of thermal insulation evaluation. Hybrid methodologies facilitate the simulation of prolonged or extreme conditions that are often impractical to physically assess. Calibrated digital instruments such as EnergyPlus, TRISCO, ABAQUS, Delphin, and COMSOL are particularly effective. Especially for tropical climates, hybrid methodologies offer a robust framework for improving the design, applicability, and performance of building insulation systems.
