Abstract

In the current digital era, door security extends beyond traditional physical keys, requiring more sophisticated features and advantages. This research aims to design an innovative smart door lock prototype using RFID technology, biometric fingerprint sensors, vibration sensors, buzzers, and Blynk application based on the Internet of Things. The implementation of this IoT-based door security system is expected to overcome the problems of physical keys by offering an effective, secure, and adaptive solution to modern security demands. This study employs the Design Science Research Process (DSRP) method, which is a research paradigm focusing on creating designs to answer questions relevant to human problems. DSRP combines empirical, rational, and systematic aspects in data collection and hypothesis testing. The results show that the smart door lock prototype was successfully designed using the ESP32 microcontroller. Access control, monitoring, and notifications can be accessed through the Blynk application.Dalam era digital saat ini, keamanan pintu melampaui sekadar kunci fisik, menuntut fitur dan keunggulan yang lebih canggih. Tujuan penelitian ini adalah perancangan purwarupa pintu pintar (smart door lock) yang inovatif, menggunakan teknologi RFID, sensor sidik jari biometrik, sensor getar, buzzer, dan aplikasi blynk berbasis Internet Of Things. Penerapan sistem keamanan pintu berbasis IoT ini diharapkan mampu mengatasi permasalahan kunci fisik, dengan menawarkan solusi yang efektif, aman, dan adaptif terhadap tuntutan keamanan modern. Penelitian ini menggunakan metode Design Science Research Process (DSRP), yang merupakan paradigma penelitian yang fokus pada penciptaan desain untuk menjawab pertanyaan yang relevan dengan permasalahan manusia. DSRP menggabungkan aspek rasional empiris dan sistematis dalam pengumpulan data dan pengujian hipotesis. Hasil penelitian ini menunjukkan bahwa perancangan purwarupa smart door lock berhasil dibuat menggunakan mikrokontroler ESP32.  Kontrol akses, monitoring, notifikasi dapat di akses melalui aplikasi Blynk.

Abstract

Banana trees that are used as producers of natural dyes are plantains, thin skin bananas, and kapok bananas. The purpose of this study was to apply natural coloring agents from various types of banana stems such as Raja Banana, Kepok Banana,and Thin Skin Banana with various natural color pigments. Making natural dyes with stems banana and water solvent in a ratio of 1: 5. Color locking on a fabric with several fixators. Fixers used are alum (Al2 (SO4) 3), tunjung (FeSO4) and lime (CaCO3). Fabrics that have optimal fastness to washing with Gray Scale are fabrics with alum fixers and lime with grades 4-5 (Good). Fabrics that have color fastness to washing (Staining Scale) which are fabrics with alum fixers and chalk with a value of 5 (Very Good). Fabrics that have resistance to dry and wet rubbing are fabrics with alum fixers and lime with grades 4-5 (Good). Dyes on the plantain stems are sharper compared to the banana stems and thin skin banana stems, with reflectance values (R%) of 74.29.

Abstract

In general, natural dyes for textile materials are obtained from extracts part of the plants such as roots, wood, leaves, seeds, and flower. Textile industry especially batik craftsman, have known many plants that can dye textile materials, such as indigo (indigofera), soga tingi bark (Ceriops tagal), tegeran wood (Cudraina javanensis), turmeric (Curcuma), tea (The), noni root (Morinda citrifelia), soga jambal bark (Pelthophorum ferruginum), kesumba (Bixa orelana), and guava leaf (Psidiumguajava). Soga tingi bark chosen because it can produce tannins which can be used as natural dyes. The purpose of this research was to obtained tannin content in soga tingi bark as qualitatively and quantitatively. The analysis carried out is FTIR and HPLC method. FTIR analysis carried out to determine of the compounds contained in the soga tingi bark extraction. Based on FTIR analysis it can be seen that there are O-H and N-H group in the wavenumber 3375,13 cm-1. C=O bond at wavenumber 1739,16 cm-1. C=C bond at wavenumber 1624,31 cm-1. C-H bond at wavenumbers 2970,72 cm-1, 1456,39 cm-1, and 1365,74 cm-1. NO2 bond at wavenumber 1365,74 cm-1. C-N bond at wavenumbers 1228,69 cm-1 and 1217,34 cm-1. And C-O bond at wavenumbers 1228,69 cm-1, 1217,34 cm-1, and 1052,3 cm-1. While HPLC analysis carried out to determine contains tannin level in the soga tingi bark extraction. HPLC conditions used are Flowrate: 1 mL/min, Mobile phase: MeOH : H2O (50:50), λ: 271 nm and Column: C18, 250 mm. Based on HPLC analysis it is known that the contains tannin level in the soga tingi bark extraction is 22,44 ppm.
