Abstract

This study discusses the concept of flexibility in Interior Design that can be applied to posyandu spaces to support the effectiveness and efficiency of providing temporary posyandu spaces. The purpose of this study is to propose more effective and efficient interior concept idea for the posyandu space, both in terms of time and effort, without compromising the function of the space itself. The implementation of routine posyandu activities has proven to have a good impact on the health status of children under five. In this case, the provision of space for posyandu activities needs to be continuously improved to improve health services in Indonesia. The research was conducted by qualitative approach with literature studies and case studies as the main sources of reference. The results of this study indicate that the posyandu space has several spatial characteristics, such as (1) independent and temporary, (2) multifunctional, (3) serving at least 5 (five) series of activities, and (4) requiring a storage area. To support these characteristics, this study carries the idea of flexibility in interior design that is collapsible/demountable and also movable. An example of this concept is also given to provide initial reference of flexibility in interior design that can be applied for posyandu.

Abstract

This study evaluates the thermal performance of the building envelope at the Banten Provincial Language Office through an analysis of the Overall Thermal Transfer Value (OTTV). The objective of this study is to calculate the OTTV value and identify the facade elements that contribute the greatest heat load to ensure compliance with the SNI 03-6389-2020 standard (maximum 35 W/m²). The primary method used was a mixed-methods approach employing a case study methodology, which involved field observations, analysis of construction drawings, and an OTTV spreadsheet calculator provided by the Ministry of Public Works and People’s Housing (PUPR). The main results show that the current OTTV value is 69.43 W/m², which does not meet the national standard. The east facade contributes the highest heat gain (85.10 W/m²) due to a window-to-wall ratio (WWR) of 54.72% and 8 mm-thick clear glass. Building orientation, materials, glass type, opening area (WWR), and the use of shading systems are critical factors in calculating the OTTV value. Modifying the glass material by using Stopray Double Glass on the east and north facades successfully reduced the total OTTV value by 50.02% to 34.70 W/m². This material intervention proved effective in meeting national energy conservation standards.
