Abstract

Wearable devices like the OH1 are increasingly used for real-time health monitoring, particularly for measuring heart rate (BPM). However, their accuracy is often compromised by motion artifacts, introducing significant noise into the measurements. This study specifically addresses the issue of noise generated by the OH1 wearable device during eleven different hand movements. To tackle this problem, we implemented a precise experimental setup involving device calibration, stable testing conditions, and participant training to ensure high consistency in hand movements. Additionally, machine learning algorithms were employed to separate noise from desired hand movement data. Our results indicate that certain hand movements, such as lifting arms and shoulder rotations, produce higher noise levels, while others, like placing hands on the table, generate minimal noise. These findings provide valuable insights for developing effective noise reduction algorithms, ultimately enhancing the accuracy and reliability of BPM measurements from wearable devices.

Abstract

Indonesia merupakan salah satu negara dengan aktivitas seismik tinggi karena terletak pada zona pertemuan tiga lempeng tektonik besar. Salah satu metode untuk memperkuat struktur bangunan agar tahan terhadap gempa adalah dengan menggunakan pengaku (bracing). Dalam penelitian ini, struktur portal bracing eksentrik (EBF) dengan eksentrisitas 25 cm dan 15 cm. Uji dilakukan dengan memberikan beban lateral yang sama pada masing-masing portal dan kemudian dibandingkan tegangan dan regangan yang terjadi. Hasil penelitian menunjukkan bahwa portal dengan eksentrisitas lebih kecil mampu mehanan beban lateral yang lebih besar, dengan regangan maksimum yang lebih kecil. Tegangan maksimum terbesar terjadi pada portal dengan eksentrisitas 25 cm, namun struktur dengan eksentrisitas 15 cm lebih optimal dalam menahan beban lateral. Penelitian ini diharapkan dapat menjadi refrensi dalam perencanaan dan perancangan struktur bangunan tahan gempa yang lebih efektif. Kata Kunci: Bracing, Eksentrisitas, Tegangan, Regangan, Beban Lateral

Abstract

This research delves into the significant role of architectural design in advancing mental well-being and its potential to address depression. In the midst of an era filled with pressure and stress, understanding the interconnection between the physical environment and mental health becomes increasingly vital. The research aims to identify architectural design principles that positively impact individual psychological aspects, encompassing elements such as natural lighting, spatial arrangement, access to nature, and art integration. The findings of this research indicate that architecturally responsive design to psychological needs has the potential to be a key factor in addressing the challenges of depression. By providing an environment that supports mental recovery, architectural design can play a crucial role in enhancing the overall well-being of society. The practical implications of this research provide impetus for architects, urban planners, and policymakers to create built spaces that are not only visually appealing but also contribute to individual psychological well-being. In summary, this research emphasizes that incorporating the dimension of mental well-being into built environment design has a significant positive impact in creating a holistically healthier society. Keywords: Architecture; Depression; Mental disorders; Mental recovery Abstrak Penelitian ini menyelidiki peran yang signifikan dari desain arsitektur dalam memajukan kesejahteraan mental dan potensinya untuk mengatasi depresi. Di tengah-tengah era yang dipenuhi tekanan dan stres, pemahaman akan keterkaitan antara lingkungan fisik dan kesehatan mental menjadi semakin penting. Penelitian ini bertujuan untuk mengidentifikasi prinsip-prinsip desain arsitektur yang memiliki dampak positif pada aspek psikologis individu, mencakup elemen-elemen seperti pencahayaan alami, pengaturan ruang, akses ke alam, dan integrasi seni. Temuan dari penelitian ini menunjukkan bahwa desain arsitektur yang responsif terhadap kebutuhan psikologis memiliki potensi menjadi faktor kunci dalam menghadapi tantangan depresi. Dengan menyediakan lingkungan yang mendukung pemulihan mental, desain arsitektur dapat berperan penting dalam meningkatkan kesejahteraan masyarakat secara keseluruhan. Implikasi praktis dari penelitian ini memberikan dorongan kepada arsitek, perencana kota, dan pembuat kebijakan untuk menciptakan ruang binaan yang tidak hanya menarik secara visual, tetapi juga berkontribusi pada kesejahteraan psikologis individu. Secara singkat, penelitian ini menegaskan bahwa memasukkan dimensi kesejahteraan mental dalam perancangan lingkungan binaan memiliki dampak positif signifikan untuk menciptakan masyarakat yang lebih sehat secara holistik.

Abstract

This article discusses the Supreme Court Decision No. 1400 K/Pdt/1986, which permits the registration of interfaith marriages in Indonesia as a response to the legal gap in the Marriage Law. Using a normative approach, a statute approach, and a comparative approach, this study finds that the Indonesian legal system emphasizes religious legitimacy before marriage registration is carried out. In contrast, the legal systems in the Netherlands and Turkey base marriage validity primarily on civil registration. Based on these findings, the study recommends adopting a European-style civil registration system to ensure legal certainty while respecting religious diversity in Indonesia.

Abstract

This thesis aims to examine and critique the concept of gender in feminist interpretations of the Qur’an through a comparative (muqarran) study of contemporary exegeses. The study’s background highlights a shift in the meaning of “gender” from a biological category of sex to a social construct that can alter perceptions of a person’s sex, and the impact of this shift on the interpretation of Qur’anic verses concerning women specifically issues of leadership (Qur’an, an-Nisaʾ 4:34), polygyny (an-Nisaʾ 4:3), and inheritance distribution (an-Nisaʾ 4:11). The author analyzes contemporary tafsirs as an effort to clarify and counteract distortions in the interpretation of these Qur’anic verses related to the concept of gender. This research uses a qualitative method with a library-based approach and comparative (muqarran) analysis to contrast different interpretations. The study maps the methods and interpretive tendencies of feminist exegetes such as Amina Wadud, Zaitunah Subhan, and Nasaruddin Umar, and compares them with contemporary tafsirs including Tafsīr al-Munīr by Wahbah az-Zuhailī, Tafsīr al-Azhar by Buya Hamka, and Tafsīr al-Misbāḥ by Quraish Shihab. The findings identify several critiques of feminist interpretations of the gender concept: (1) feminist readings consistently emphasize that women are discriminated against by men in Islamic teachings and the Qur’an—portraying Islam as perpetuating patriarchal culture—which may create the misconception that Islam is discriminatory toward women; (2) there are misconceptions about the concept of gender from an Islamic perspective, such as treating gender as a form of relativism that precludes absolute truth, and using the gender concept to justify sexual deviations (e.g., the increasing visibility of LGBT cases); and (3) several negative social impacts of feminist exegesis on Muslim communities, for example: declining marriage rates due to women’s reluctance to accept male leadership in the household, widespread rejection and moves to prohibit polygyny, and resistance to Qur’anic inheritance rules. The thesis concludes by underlining the need for critical reading of feminist gender concepts in Qur’anic interpretation and for comparing them with other contemporary tafsirs. Such balanced readings—attending both to text and context—can correct conceptual and practical deviations in the discourse on gender among Muslim communities, and prevent Islam from being perceived as discriminatory toward women. Islam, in fact, upholds the dignity and worth of every human being, both male and female, and is rahmatan lil-ʿālamīn.
