Latar Belakang: Kegagalan perawatan karies gigi dapat terjadi jika mineral intrafibrillar dentin tidak teremineralisasi secara biomimetik. Semen ionomer kaca (SIK) merupakan bahan restorasi gigi dengan kemampuan melepaskan ion kalsium yang merupakan bahan baku remineralisasi. Carboxymethyl chitosan (CMC) merupakan analog protein non-kolagen alami yang terbukti dapat menstabilkan ion kalsium fosfat dalam keadaan amorf dalam proses remineralisasi biomimetik. Pencampuran kedua bahan tersebut berpotensi menghasilkan bahan restorasi baru yang dapat meremineralisasi dentin secara biomimetik. Tujuan: Mengevaluasi hasil remineralisasi dentin yang tedemineralisasi setelah aplikasi material modifikasi SIK dengan CMC 5% dan 10% dengan memeriksa perubahan morfologi dan komposisi ion kalsium dentin. Metode: Proses remineralisasi dilakukan dengan mengaplikasikan material SIK, SIK-CMC 5% dan 10% selama 14 hari pada kavitas dentin yang terdemineralisasi dengan EDTA 17% selama 7 hari. Evaluasi morfologi dilakukan dengan Scanning Electron Microscope (SEM) dan nilai komposisi ion diperiksa dengan Energy Dispersive X-ray (EDX). Hasil: Terlihat perubahan morfologi tubulus dan permukaan dentin setelah aplikasi bahan SIK, SIK-CMC 5%, dan SIK-CMC 10% selama 14 hari yang dievaluasi dengan SEM. Hasil pemeriksaan EDX memperlihatkan peningkatan kandungan ion kalsium dan pembentukan hidroksiapatit setelah aplikasi material SIK-CMC 10%. Kesimpulan: Aplikasi modifikasi SIK dengan CMC berpengaruh terhadap perubahan morfologi dan komposisi ion kalsium pada dentin yang terdemineralisasi. ......Background: Failure of dental caries treatment can occur if intrafibrillar dentin minerals are not biomimetically mineralized. Glass ionomer cement (GIC) is a dental restoration material with the ability to release calcium ions which are the raw material for remineralization. Carboxymethyl chitosan (CMC) is a natural non-collagen protein analogue which has been proven to stabilize calcium phosphate ions in an amorphous state in a biomimetic remineralization process. Mixing these two materials has the potential to produce new restorative materials that can biomimetically remineralize dentin. Objective: To evaluate the remineralization results of demineralized dentin after application of GIC modified material with 5% and 10% CMC by examining changes in the morphology and composition of dentin calcium ions. Method: The remineralization process was carried out by applying SIK material, SIK-CMC 5% and 10% for 14 days to the demineralized dentin cavity with 17% EDTA for 7 days. Morphological evaluation was carried out using a Scanning Electron Microscope (SEM) and ion composition values were examined using Energy Dispersive X-ray (EDX). Results: Changes in tubule morphology and dentin surface were seen after application of SIK, SIK-CMC 5%, and SIK-CMC 10% for 14 days as evaluated by SEM. The EDX examination results showed an increase in calcium ion content and hydroxyapatite formation after application of 10% SIK-CMC material. Conclusion: Application of GIC modification with CMC affects changes in morphology and calcium ion composition in demineralized dentin. ​

Abstrak :
Bio-inspired design (also called biomimetics or biomimicry) is a promising approach for the development of innovative technical products – not only in mechanical engineering, but also in areas such as material science and even computer engineering. Innovations such as humanoid robots or multifunctional materials have shown the potential of bio-inspired design. However, in industrial companies, bio-inspired design remains an “exotic” approach which is rarely used in innovation practice. One reason for this is a lack of knowledge on how to implement bio-inspired design in practice. Therefore, this guide book was written to explain the application of bio-inspired design methods and tools. The target groups are professional engineers and biologists, as well as students of both disciplines. The book presents a selection of methods for specific activities in bio-inspired design, namely: planning a bio-inspired design project, abstraction, search, analysis and comparison, and transfer of analogies. Factsheets give an overview of each method, its advantages and challenges, and its suitability for different bio-inspired design approaches and scenarios. To facilitate understanding, all methods are explained with the help of the same example. In addition, ten best practice examples show the practical applicability of bio-inspired design.

Dalam beberapa tahun terakhir, desain komputasional telah mengubah paradigma desain tradisional dengan memungkinkan penciptaan desain yang lebih efisien melalui teknik digital. Salah satu permasalahan utama yang dihadapi arsitek di era digital ini adalah tantangan dalam menghasilkan desain berkelanjutan untuk menjaga keberlangsungan hidup antara manusia dan alam. Biomimetik, pendekatan yang meniru strategi dan prinsip alam, dapat menjadi solusi dalam menghadapi tantangan ini. Studi ini membahas implementasi pendekatan biomimetik dalam desain komputasional untuk menghasilkan sebuah visualisasi proses desain biomimetik hingga akhirnya dapat menghasilkan desain inovatif berbasis alam. Studi ini dilakukan melalui studi literatur, kuesioner, dan studi kasus. Studi kasus dilakukan dengan mengimplementasi pendekatan biomimetik dalam proses desain komputasional, sehingga dapat menciptakan envelope bangunan yang adaptif terhadap konteks lingkungan terutama intensitas cahaya matahari. Proses ini akan melibatkan tiga tahap utama yaitu knowledge, abstraction, dan application. Ketiga tahap ini dilewati dengan pemahaman mendalam terhadap prinsip-prinsip biologis dan adaptasinya dalam konteks desain arsitektur. Tujuan dari studi ini adalah mengivestigasi potensi integrasi pendekatan biomimetik dengan desain komputasional, serta memberikan visualisasi proses desain komputasional yang mengimplementasikan pendekatan biomimetik dalam menghasilkan sebuah envelope bangunan yang mengadaptasi prinsip alam. ......In recent years, computational design has transformed the traditional design paradigm by enabling the creation of more efficient designs through digital techniques. One of the main challenges faced by architects in this digital era is the need to produce sustainable designs to maintain the coexistence between humans and nature. Biomimetic, an approach that mimics the strategies and principles of nature, can provide a solution to this challenge. This study discusses the implementation of the biomimetic approach in computational design to produce a visualization of the biomimetic design process, ultimately leading to innovative nature-based designs. The study is conducted through literature review, questionnaires, and case studies. The case study involves implementing the biomimetic approach in the computational design process to create a building envelope that adapts to the environmental context, particularly sunlight intensity. This process involves three main stages: knowledge, abstraction, and application. These stages are undertaken with a deep understanding of biological principles and their adaptation in the context of architectural design. The aim of this study is to investigate the potential integration of the biomimetic approach with computational design and provide a visualization of the computational design process that implements the biomimetic approach in creating a building envelope that adapts natural principles.
