Abstract

Parametric design is a new architectural design approach which is developing for the last decade. This development is supported by the advance of digital architecture technology, allowing designers to engage in complex geometry modelling and design optimization efficiently using parametric design software. One of parametric design software, Rhinoceros-Grasshopper, has been interconnected to several building simulation packages, which gives new usefulness for architectural design process. Parametric design is likely to be a standard skill that should be possessed by Architect in the future. This study discusses parametric design application for architectural design process and its trend for the context of architectural education in Indonesia. It aims to give a strategy and model instruction for parametric design teaching, especially in the university level. Literature review and Youtube Channel exploration were conducted to discuss the implementation of parametric design. In order to examine the trend of parametric design in Indonesia, the data analysis was conducted based on channel analytics from one of Youtube channel promoting parametric design and survey aiming architecture lecturer.

Abstract

As the world's second-largest coal exporter, Indonesia faces complex dynamics in managing its coal export realizations amid domestic policy obligations and market fluctuations. This phenomenon is increasingly significant given coal's strategic role as a major source of state revenue and its position as a primary energy supplier to Asian emerging markets, particularly China and India. This study aims to analyze the determinants affecting Indonesia's coal export realizations. The research employs a quantitative approach using quarterly time-series data from 2014 to 2023, comprising 40 observations. The analytical methods utilized are the Vector Error Correction Model (VECM) to examine both short-term dynamics and long-term equilibrium relationships among variables. The independent variables examined include coal production volume, domestic market obligation (DMO), selling price, coal reserves, and mineral and coal sector investment, with coal export realization as the dependent variable. The findings reveal that simultaneously, all independent variables significantly influence coal export realizations. Partially, coal production, selling price, coal reserves, and investment demonstrate significant positive effects on export realizations. Conversely, domestic market obligation shows a significant negative effect on Indonesia's coal export realizations, indicating that mandatory domestic supply requirements constrain export volumes.
