Abstract

pendahuluan: Bahan cetak alginat merupakan bahan cetak yang sering digunakan di bidang kedokteran gigi dan dapat mengalami perubahan dimensi akibat proses sineresis dan imbibisi yang dapat menyebabkan distorsi hasil cetakan. Untuk mencegah terjadinya perubahan dimensi, maka dilakukan penambahan bahan alami seperti pati beras ketan putih pada bahan cetak alginat. Penelitian ini bertujuan untuk menganalisis perbedaan efek penambahan pati beras ketan putih konsentrasi 40%, 50%, dan 60% pada bahan cetak alginat setelah 5, 10 dan 15 menit pencetakan terhadap stabilitas dimensi hasil cetakan alginat. Metode: Rancangan penelitian ini yaitu eksperimental laboratoris. Sampel yang digunakan adalah hasil cetakan alginat yang diisi gipsum tipe III yang diperoleh dari model induk cincin dengan ukuran diameter dalam 12,55 mm dan tinggi 19 mm. Jumlah sampel yang digunakan sebanyak 60 sampel yang terdiri dari 12 kelompok perlakuan. Sampel diukur menggunakan kaliper digital kemudian dianalisis dengan uji Anova satu arah dan dilanjutkan dengan uji LSD (Least Significance Difference). Hasil: Hasil uji Anova satu arah menunjukkan ada pengaruh (p<0,05)  penambahan pati beras ketan putih konsentrasi 40, 50, dan 60% setelah 5 menit pencetakan (A1,  B1.1, B1.2, B1.3) dengan nilai p=0,043 ,setelah 10 menit pencetakan (A2, B2.1, B2.2, B2.3) dengan nilai p=0,0001, dan setelah 15 menit pencetakan (A3, B3.1, B3.2, B3.3) dengan nilai p=0,011. Hasil uji LSD menunjukkan ada perbedaan pengaruh signifikan pada seluruh kelompok dengan nilai (p<0,05). Simpulan: Penambahan pati beras ketan putih konsentrasi 40, 50, dan 60% pada bahan cetak alginat memiliki pengaruh terhadap stabilitas dimensi hasil cetakan dan penambahan pati beras ketan putih 50% menghasilkan stabilitas dimensi hasil cetakan terbaik.

Abstract

Abstract. This study aims to analyze: 1) The legal implications of notarial digitization on the validity of notarial deeds. 2) Obstacles and solutions in the notarial digitization process related to the validity of notarial deeds. This type of research falls within the scope of normative legal research. The approach method in this study is a statute approach. The type and source of data in this study are secondary data obtained from literature studies. The analysis in this study is prescriptive. The results of the study conclude: 1) The digitalization of notarial deeds has a significant impact on the validity of notarial deeds, especially because the formal requirements for authentic deeds as stipulated in Indonesian positive law have not yet been met. Although Article 5 paragraph (4) of the ITE Law recognizes electronic documents as legal evidence, the absence of explicit provisions in the Notary Law (UUJN) means that digital notarial deeds cannot yet be equated with conventional authentic deeds. As a result, electronic deeds risk losing their full evidentiary power before the law, creating legal uncertainty, and threatening the protection of the parties' rights. Therefore, regulatory reform containing specific provisions regarding electronic notarial deeds is an urgent need to guarantee validity, evidentiary power, and balanced legal protection in the digital era. 2) In its implementation, the digitalization of notarial deeds faces various obstacles such as legal vacuums, procedural uncertainty, threats to electronic data security, limited understanding of technology among notaries, and the absence of uniform operational standards. These obstacles can hinder the implementation of valid and effective digital deeds. To address this, concrete solutions are needed in the form of comprehensive regulatory updates, the development of digital-based standard operating procedures, strengthening information technology security systems, improving notary digital literacy through ongoing training, and strengthening cross-institutional collaboration.
